[0031] Sand blasting is a workpiece surface treatment process, which uses compressed air as power to form a high-speed jet beam, and high-speed sand is sprayed to the surface of the workpiece to be treated, so that the appearance or shape of the workpiece surface is changed. In the related art, the sand blasting device in handheld spraying processing is usually provided with a chamber in the shell for isolating the sand blasting space from the external environment. The operator puts on gloves and operates the tool to perform sand blasting processing. The sand used for sand blasting is usually designed for one-time use or only has a simple collection structure, and it is difficult to realize the recycling of sand. There are problems of resource waste, low recovery efficiency and environmental pollution.

[0032] The sand blasting device in the conventional technology often lacks an efficient sand recycling system, resulting in low utilization rate of sand during sand blasting, and frequent replenishment of new sand, which increases the operation cost and time. In addition, some sand blasting devices usually use simple gravity sedimentation or filtration method in sand recycling. This method not only has low recovery efficiency, but also easily causes sand blockage or wear, affecting the sand blasting quality and equipment life.

[0033] The following refers to the drawings Figure 1 to the drawings Figure 4 The utility model discloses a circulating sand blasting device, and the utilization rate of sand resource is high, and the recycling efficiency is high.

[0036] The sand blasting assembly 200 comprises a sand blasting head 210, a sand supply pipe 220, a transfer bin 230 and a sand blasting driving mechanism 240. The transfer bin 230 is connected to the machine shell 100. The inlet of the sand blasting head 210 is connected to one end of the sand supply pipe 220. The other end of the sand supply pipe 220 is connected to the outlet of the transfer bin 230. The output end of the sand blasting driving mechanism 240 is connected to the inlet of the sand blasting head 210. The circulating pipe 160 is connected to the inlet of the transfer bin 230 away from the recovery bin 140 to realize the communication between the recovery bin 140 and the transfer bin 230.

[0037] The recovery auxiliary assembly 300 comprises a recovery filter screen 310, an elastic member 320, a bracket 330 and a vibration motor 340. The recovery filter screen 310 is arranged in the working cavity 110. The recovery filter screen 310 is located above the recovery bin 140 and below the observation window 120, the partition operation sleeve 130 and the sand blasting head 210. The opposite ends of the elastic member 320 are connected to the recovery filter screen 310 and the machine shell 100 respectively. The elastic member 320 enables the recovery filter screen 310 to realize small-amplitude motion in the working cavity 110 and enables the position of the recovery filter screen 310 in the working cavity 110 to realize dynamic balance. The bracket 330 is connected to the vibration motor 340. Preferably, the bracket 330 is cross-shaped and the surface of the bracket 330 is arc-shaped structure, which can effectively avoid the sand reaching the bracket 330 and stopping falling and effectively improve the effect of sand recovery and circulation. The bracket 330 is connected to the machine shell 100. The driving end of the vibration motor 340 is connected to an eccentric block 341. The bottom of the recovery filter screen 310 is provided with a vibrating member 311. The vibrating member 311 is located on one side of the eccentric block 341. The vibration motor 340 is used to drive the vibrating member 311 to move through the eccentric block 341. The top of the recovery filter screen 310 is provided with a material guide table 312. The material guide table 312 is a pyramid narrowing from bottom to top. The eccentric block 341 and the vibration motor 340 are located directly below the material guide table 312. The horizontal projections of the eccentric block 341 and the vibration motor 340 are located in the horizontal projection of the material guide table 312. Through the material guide table 312, the probability of sand falling to the structure such as the eccentric block 341 can be significantly reduced, thereby reducing problems such as jamming and collision damage.

[0038] The hands of the operator are inserted into the partition operation sleeve 130, one hand holds the jig for clamping and sandblasting products, and the other hand operates the sandblasting head 210. The sandblasting driving mechanism 240 supplies a positive pressure driving force to the sandblasting head 210, and the sand material is sprayed out of the sandblasting head 210, thereby sandblasting the sandblasting products. After sandblasting, the sand material falls into the recovery screen 310. The vibration motor 340 drives the eccentric block 341 to rotate, thereby driving the vibration piece 311 to move. Under the elastic action of the elastic piece 320, the recovery screen 310 forms vibration, thereby enabling the sandblasting sand material on the recovery screen 310 to effectively fall through the mesh of the recovery screen 310 and enter the recovery bin 140. The circulating driving mechanism 150 applies a positive pressure driving force to the circulating pipe 160, thereby driving the sand material in the recovery bin 140 to pass through the circulating pipe 160 to the transfer bin 230, which can be used in the sandblasting head 210.

[0039] By setting the recovery bin 140, the circulating driving mechanism 150 and the circulating pipe 160, the automatic recovery and recycling of sand material are realized, which greatly improves the utilization rate of sand materials such as steel balls and quartz sand, effectively saves sand material resources, is friendly to the environment, and has low sandblasting cost. At the same time, the design of the circulating driving mechanism 150 enables the sand material to be continuously and stably supplied to the sandblasting head 210, effectively ensuring the stability and continuity of the sandblasting operation, and effectively ensuring the sandblasting processing efficiency. Through the special combination design of the recovery screen 310, the elastic piece 320, the bracket 330 and the vibration motor 340, the recovery screen 310 can produce small amplitude vibration in the working cavity 110, which can promote the uniform distribution and rapid falling of the sand material, effectively reduce the probability of blockage of steel balls at the recovery screen 310, effectively improve the passing efficiency of the sand material at the recovery screen 310, thereby effectively improving the recovery efficiency of the sand material, and ensuring the sandblasting effect of the sandblasting head 210 through the recovered sand material. In addition, the design of the material guide table 312 not only optimizes the falling path of the sand material, reduces the direct contact of the sand material with the eccentric block 341 and other structures, reduces the risk of jamming and collision damage, but also improves the reliability and durability of the equipment. The design of the observation window 120 and the partition operation sleeve 130 enables the operator to clearly observe the inside of the working cavity 110 without directly contacting harmful dust, thereby enabling more accurate control of the sandblasting process, improving the safety and convenience of the operation.

[0040] It can be understood that the bottom of the recovery screen 310 is also provided with an isolation cover 350, which surrounds the eccentric block 341 and the vibration motor 340. Through the isolation cover 350, the working performance of the vibration motor 340 and the eccentric block 341 can be effectively improved, and the sand material falling through the recovery screen 310 can be effectively prevented from reaching the vibration motor 340 and the eccentric block 341, thereby effectively improving the working performance of the recovery auxiliary assembly 300.

[0041] It can be understood that the elastic member 320 is a spring, and a plurality of springs are arranged uniformly at the edge of the recovery filter screen 310, and the opposite ends of each spring are connected to the recovery filter screen 310 of the machine shell 100, which can effectively improve the stability of the action of the recovery filter screen 310 when vibrating.

[0042] Specifically, the end of the spring away from the machine shell 100 is connected to the bottom of the recovery filter screen 310, and the bottom of the recovery filter screen 310 is also provided with a lower surrounding blocking member 313 in the form of a ring, and each spring surrounds the periphery of the lower surrounding blocking member 313, and the lower surrounding blocking member 313 is used to separate the springs to the periphery of the working cavity 110, which can effectively prevent the sand falling through the recovery filter screen 310 from reaching the spring, and can effectively improve the working performance of the recovery auxiliary assembly 300.

[0043] It can be understood that the inner wall of the machine shell 100 is provided with an upper surrounding blocking member 111 above the recovery filter screen 310, which is used to block the gap between the recovery filter screen 310 and the inner wall of the machine shell 100, which can effectively prevent the sand produced during the sandblasting process from falling directly from the gap between the recovery filter screen 310 and the inner wall of the machine shell 100 to affect the recovery effect, and the overall circulating recovery action is stable and reliable.

[0044] It can be understood that the upper surrounding blocking member 111 is in the form of a ring, and the inner side of the upper surrounding blocking member 111 is in the form of a taper narrowing from top to bottom, and the inner side of the upper surrounding blocking member 111 can form a good guiding effect on the sand produced during the sandblasting process, so that the sand can smoothly reach the upper surface of the recovery filter screen 310, which can further prevent the sand produced during the sandblasting process from reaching the recovery filter screen 310 and the inner wall of the machine shell 100, and can further improve the reliability of the overall circulating recovery action.

[0045] It can be understood that the sandblasting driving mechanism 240 includes an air compressor 241 and a pressurizing pipe 242, and the opposite ends of the pressurizing pipe 242 are connected to the output end of the air compressor 241 and the inlet of the sandblasting head 210, respectively, and the sandblasting head 210 is pressurized by the air compressor 241 cooperating with the pressurizing pipe 242, which can effectively improve the kinetic energy of the sandblasting head 210, thereby effectively improving the sandblasting effect.

[0046] It can be understood that the sandblasting assembly 200 further comprises a replenishment pipe 250, one end of the replenishment pipe 250 is connected to the inlet of the transfer bin 230, the other end of the replenishment pipe 250 is used to connect an external sand replenishment bin, and the sand in the sand replenishment bin is driven by a pumping structure to enter the transfer bin 230 through the replenishment pipe 250, which can effectively supplement the amount and quality of the sand used for sandblasting, and can effectively ensure the sandblasting processing effect.
