[0057] In example 1, under the driving of the air cylinder 12, the lifting taking door 3 slides upward to open the taking port. The worker places the sewing machine parts on the placing plate 5. Under the driving of the air cylinder 12, the lifting taking door 3 descends to close the taking port. The worker inserts both hands into the operation hole 9. The worker can observe the sand blasting condition in the sand blasting shell 1 through the window 2. The worker wears a sand blasting glove. The worker holds the sewing machine parts on the placing plate 5 with one hand and takes the sand blasting gun from the sand blasting gun hook 11 with the other hand.

The dust-containing gas extracted by the branch dust extraction pipe 32 rises along the outer cylinder 27 to the inner cylinder 28, and then is output to the dust extraction main pipe 24 by the inner cylinder 28. The dust-containing gas extracted by the side air duct 29 and the branch dust extraction pipe 32 is uniformly transported to the pulse bag dust collector through the dust extraction main pipe 24.

[0064] The electric screw rod elevator 35 drives the regulating valve flap 23 to rise or fall through the valve rod 26, the regulating valve flap 23 can adjust the opening size of the dust extraction port of the inner cylinder 28 when it rises, and when it rises to the uppermost position, the regulating valve flap 23 closes the inner cylinder 28 to stop dust removal.

[0065] When the regulating valve flap 23 falls, it gradually fits the inner wall of the outer cylinder 27, closes the slag discharge port at the bottom of the outer cylinder 27, and stops dust extraction at the first dust extraction port, only dust extraction at the second dust extraction port, and the large-particle impurities generated by the cyclone dust collector 21 fall on the top surface of the regulating valve flap 23, and fall under the action of gravity when the regulating valve flap 23 rises.

[0066] After a period of use, the plug 33 is pulled out to discharge the large-particle impurities in the slag discharge funnel 31.

[0067] A group of branch dust extraction pipes 32 are evenly arranged in a ring shape on the outer wall of the lower part of the dust extraction funnel 30, and multiple branch dust extraction pipes 32 are used to make the dust extraction more uniform.

[0068] The induced draft fan 54 is started, the dust-containing gas in the sandblasting machine is sucked into the dust extraction area 53 through the dust extraction pipeline, the clean air enters the clean air area 52 after being filtered by a group of dust removal bags 49, and is output by the induced draft fan 54. When it is necessary to clean the dust removal bag 49, the electromagnetic valve is opened, the compressed air in the air storage bag 50 is output, is sprayed into the dust removal bag 49 through the nozzle, and is cleaned.

[0069] The particulate impurities separated by the dust cloth bag 49 fall on the bottom of the dust shell 48 and are discharged to the recycling box 43 through the discharge port. When the recycling box 43 is full, the L-shaped discharge plate 57 is inserted into the guide groove to close the discharge port. The worker holds the handle 47 and pulls out the recycling box 43 for dumping. After dumping is completed, the recycling box 43 is inserted into the guide groove 42 along the guide plate 44. Since the two side plates of the guide groove 42 are inwardly folded to form the elastic clamping plate 45, the side wall of the recycling box 43 can be clamped and positioned by the elastic clamping plate 45. After the recycling box 43 is pushed into position, the L-shaped discharge plate 57 is pulled out, and the particulate impurities are collected again.

[0070] The short edge of the L-shaped discharge plate 57 is upwardly raised to facilitate the worker to hold the short edge and pull out the L-shaped discharge plate 57.

[0071] Universal wheels 46 are arranged at the four corners of the bottom of the recycling box 43 to make the recycling box 43 more smooth to pull out or push in.
