The automatic sand blasting machine uses compressed air as the power to spray the sand or spray material on the surface of the product in the form of high-speed spraying, so as to achieve the effect of correcting the surface of the workpiece and changing the appearance quality of the product. This kind of equipment will inevitably have some minor faults when using it. Let's learn how to troubleshoot it.1. The problem often seen is that a large amount of abrasive enters the vacuum bag, causing the automatic sand blasting machine to malfunction. The reason for this is that the abrasive is too thin or the suction bag opening is too large. The solution is to use a coarser abrasive or to close the opening of the vacuum bag.2, the more common and more serious situation is that the abrasive sprayed by the sand blasting machine is uneven, resulting in the appearance quality of the workpiece is reduced. This may be due to too little abrasive, or blocked nozzles, or low air pressure. When this happens, you must first check which cause is caused, and then the right medicine, the problem can be solved.If you use this kind of equipment for a long time, it will inevitably have various faults. If there is a fault, you must first find out the cause of the fault, and then solve it according to your own ability. If you can't solve it yourself, ask a professional to repair it. So as not to cause serious consequences.

The blasting machine has been widely used in the foundry machinery industry. Its main function is to treat the rust layer of the metal and the oxide layer on the surface of the metal workpiece to achieve the purpose of the glazing product. So, how should I buy a sand blasting machine?First of all, considering the material, the quality of the equipment is determined by the materials used. The blasting abrasive has metal abrasives and resin abrasives. The former is strong, while the latter is soft. At the same time, dry blasting and liquid spraying are also considered. sand.Second, considering production capacity, production capacity determines production efficiency, while production efficiency directly affects economic efficiency. Automated blasting equipment is the most efficient, and everyone can choose.Finally, considering the workpiece specifications and their service life, consider the appropriate nacelle according to the size of the workpiece, so as to ensure that the equipment has enough space to complete the task. In addition, the longer the life of the equipment, the more worthy of our choice.

Sand blasting machine refers to the process of using compressed air to transport powdery particles (1~4mm in diameter) from one place to another in the pipeline. During the process of converting kinetic energy into potential energy, the high-speed moving sand scouring the surface of the object. Thereby achieving the effect of improving the surface quality of the object. (In short, it is the improvement of the surface of the product). The type of sand blasting machine is usually divided into a dry blasting machine and a wet blasting machine, and is also divided into an automatic blasting machine and a manual blasting machine.1) Dry automatic sand blasting machine is divided into conveying type automatic blasting machine and rotary type automatic blasting machine, drum type automatic blasting machine, crawler type automatic blasting machine, etc.2) Manual dry blasting machine is divided into ordinary open type mobile manual blasting machine, high pressure open type mobile manual blasting machine, general pressure box type manual blasting machine, high pressure box type manual blasting machine, etc.

Fully automatic includes automatic blasting, automatic workpiece entry and exit, automatic gun oscillating, automatic abrasive sorting, automatic dust removal, etc. He uses compressed air as the power and metal abrasive as the medium.The types of fully automatic blasting machines can be divided into:1) Conveying automatic sand blasting machineConveyor type automatic blasting machine is also called plane automatic blasting machine and pipeline blasting machine. The whole process can be completed automatically. 2) Rotary type automatic sand blasting machineThe rotary automatic sand blasting machine is also called rotary automatic sand blasting machine, gap type automatic blasting machine and continuous automatic blasting machine. It is a high-capacity, high-efficiency automatic sand blasting machine.3) Track type automatic sand blasting machineThe crawler type automatic blasting machine is also called the drum type automatic blasting machine. He belongs to a high-volume, high-efficiency automatic sand blasting machine, but has the disadvantage that the product cannot be used without fear of collision. Manually pour all the products that need sand blasting into the blasting chamber, close the door, set the blasting time, and after the blasting is completed, the machine will automatically stop and manually remove the blasted product.4) Non-standard automatic sand blasting machineA sand blasting machine that is customized according to the user's product, performance, output and other requirements. The transmission mode, sand blasting method, sorting method, dust removal method and recycling method of the blasting machine equipment can be customized according to different.

We all know that there is a close contact between the safety of the blasting machine and the success of the manufacturer. So how do you save on abrasives? First and foremost in five aspects.1 Pressure is very important, directly leading to the loss of sandblasting abrasive:To make the fastest power and the lowest abrasive loss, it is necessary to know the materials and specific accurate data of the user's products, and only need to know each other and make the best results.2 Dust collector: The blasting machine is dispatched to the best orientation before use. The filter cartridge of the dust collector is eradicated on time, and the waste sand inside is removed in time to minimize the amount of abrasive used.3 Spray gun: Before using the sand blasting machine, first check if there is any wear inside the spray gun, once you see the sand nozzle. There is wear on the nozzles and other places, and timely replacement is required to indirectly avoid the waste of abrasives.4 Sand tube: Whether the sand pipe is straight or not before the sand blasting machine 5, to see a necessary operation, assuming it is curved, it will definitely be a waste of sanding.5 Separator: It is the most important part of saving abrasives. Before purchasing a sand blasting machine, you should tell the manufacturer the exact type of abrasive before the process is judged, so that the manufacturer of the sand blasting machine can combine with you well in the planning time. The standard of demand, to achieve precise control. Abrasive materials will naturally reduce the use of measurement.Guangdong Xintai Machinery specializes in production and sales: sand blasting machine, shot blasting machine, automatic blasting machine, automatic blasting machine, double blasting machine, stainless steel blasting machine, pressure blasting machine, automatic conveying blasting Machine, automatic rotary blasting machine, shot blasting machine, through-type shot blasting machine, hook type shot blasting machine and other blasting equipment.

Abrasive losses for several major reasons: dust collectors, separators, air pressure, sandblasting tubes, abrasive recovery systems.1. Regularly clean the dust in the dust collector.2. The separator is generally divided into air sorting mode and mechanical sorting mode. The user can select the corresponding separator according to the sand material used for processing the workpiece before purchase, in order to achieve better separation effect.3. The air pressure adjustment should be appropriate, and the air pressure should be adjusted according to the hardness material of the workpiece.4. Excessive bending of the sandblasting pipe will produce certain resistance to the sand material, increase the impact of the abrasive on the sand pipe, reduce the service life of the sand pipe, and also have a certain friction between the abrasive and the abrasive.5. The wear of the spray gun will also cause the abrasive to be sprayed too much, and the abrasive loss is fast.6. The sand recycling system is also divided into pneumatic recovery and mechanical recovery. According to the sand material, the two can be used synchronously in the metal sand material.

1. When the profile is placed, it should not be too close to the edge to prevent the sand blasting from being in place; the profile and the profile should not be placed too close together to avoid uneven sandblasting on the side of the profile; in order to ensure better surface effect of the blasting material, all blasting materials must be sprayed. Sand twice. The ratio of profile spacing should be twice the height of the profile; a small shaft for special distribution between the profile and the profile should be used to separate the material from the material and keep it horizontal to enter the sand blasting machine without oscillating or close-up to avoid causing The phenomenon of uneven sand blasting and spraying is not in place.2. Before the profile enters the machine mouth, check whether the sensor indicator of the presser is illuminated to ensure the normal operation of the presser; if the indicator light is not bright, it means that the discharge distance is too far or the profile head and tail are too close, the sensor is not recognized. The distance between the profiles, at which point the sensor must be manually calibrated to properly pressurize the press before and after.3. When the profile of the profile after sand blasting is at the exit, the profile that is displaced by the first time is placed evenly to ensure that the profile is completely and evenly sprayed; the profile after the blasting must be worn with special protective gloves. In order to ensure the cleanliness of the surface of the profile, the profile cannot be touched directly by hand.

1. To see the size of the workpiece, choose a box type sand blasting machine, a mobile sand blasting machine, and an automatic blasting machine.2. To see the shape of the product, choose the specifications of the sand blasting machine. Generally, there are fixed specifications below one meter, especially for large ones or for open ones.3. The degree of product surface requirements, this specific depends on dry or wet spray, if it is dry spray, there are many choices of abrasive, wet spray is generally glass sand.4. Some accessories of the sand blasting machine should be familiar. Sandblasting guns and sandblasting gloves are often changed, because sandblasting is actually very abrasive. (1) Surface cleaning processing: metal oxide layer, carbide black skin, metal or non-metal surface rust removal, such as gravity die casting mold, rubber mold oxide or release agent removal, ceramic surface black spots, uranium color removal, Painted rebirth. (2) beautification processing: all kinds of gold, K gold jewelry, matte or surface treatment of precious metal products, crystal, glass, corrugated, acrylic and other non-metal surface processing and can make the surface of the workpiece into a metallic luster. (3) etching processing: jade, crystal, agate, semi-precious stones, seals, ya stone, antiques, marble tombstones, ceramics, wood, bamboo and other etching art. (4) pre-processing: Teflon (TEFLON), PU, ​​rubber, plastic coating, rubber roller (ROLLER), electroplating, metal spray welding, titanium plating and other pre-treatment, so that the surface adhesion increased.(5) raw edge processing: bakelite, plastic, zinc, aluminum die-casting, electronic parts, magnetic core and other raw edges. (6) stress relief processing: aerospace, defense, precision industrial parts, derusting, paint removal, finishing, and other stress relief processing. (7) Processing of electronic parts: surface and etching of silicon chips, impurity removal on the back side of wafers, overflow of electronic parts packaging, removal of printed surface of finished products, cleaning of ceramic electric heating (8) Processing of molds: sandblasting of general mold surfaces, molds Surface treatment after biting, wire cutting die, glass mold, tire mold, conductive rubber mold, shoe mold, bakelite mold, plating mold, button mold, plastic product mold. (9) Processing of large work objects: large-scale workpieces such as oil tanks, chemical tanks, hulls, copper structures, metal houses, containers, automotive industry, etc., rust removal, paint removal, maintenance and automatic surface treatment of large flat glass.
