[0022] According to the above technical scheme, the universal ball 10 and the sand collecting box 12 simultaneously contact the outer surface of the product to be sand blasted, the universal ball 10 rolls on the surface of the product during sand blasting, then according to the size of the product, the operation carriage 13 moves when in contact, thereby driving the main strip plate 25 to slide and rotate on the surface of the fixed rod 46, the second spring 24 is compressed in the process, thereby pushing the linkage strip plate 22 and the support frame 18 to move, at this time, the second spring 24 slides on the outer surface of the fixed rod 46, when the support frame 18 moves, it can also drive the auxiliary adjusting block 17 to move outside the spray gun 21, when the auxiliary adjusting block 17 moves, it drives the linkage seat 23 and the linkage block 34 to slide on the outer surface of the limiting rod 30, the linkage block 34 drives the wave-shaped guide vane 32 to fold and retract in the spray gun 21 during sliding, and pulls the baffle 33 to move to supplement the through opening 31, and when the linkage seat 23 slides outside the limiting rod 30, it can drive the reset rod 19 to slide in the U-shaped seat 35, further driving the pressure plate 28 to compress the first spring 20, so that the wave-shaped guide vane 32 reduces the flow rate of the sand and gas sprayed by the spray gun 21.

[0023] A further technical solution involves two U-shaped seats 35, each with a movably inserted reset rod 19 at the center of the side furthest from each other. A pressure plate 28 is welded to one end of the reset rod 19 on the inner side of the U-shaped seat 35. A first spring 20, which works in conjunction with the pressure plate 28, is fitted onto the outer surface of the inner side of the reset rod 19 on the outer side of the U-shaped seat 35.

The connecting plate 15 is rotatably connected, and the other end of the intermediate connecting plate 15 is movably connected to the pull plate 14. One side of the pull plate 14 is rotatably connected to the swing assembly 555. The swing assembly 555 includes two wave support rods 26 rotatably connected to one side of the pull plate 14. Each of the two wave support rods 26 has several protruding strips on its corresponding side. One side of the pull plate 14 is rotatably connected to the short rod 27, which is rotatably connected to the intermediate connecting plate 15. The reinforcing assembly 556 includes a cylinder 40 fixedly connected to one side of the operating slide 13. A pressure frame 39 is provided in the middle of the cylinder 40. Pressure members 38 are slidably mounted on the upper and lower sides of the pressure frame 39. A third spring 37 is mounted between the pressure member 38 and the pressure frame 39. The two pressure members 38 are fixedly connected to a protrusion 42 through the cylinder 40 on the side away from each other. The protrusion 42 is used in conjunction with the protruding strips.

[0024] Regarding the above technical solution, when the linkage plate 22 moves, it pushes the linkage plate 22 to move, causing the transfer connecting plate 15 to rotate on the support frame 18. After the process, it drives the short rod 27 to move, causing the pull plate 14 to move towards the operating slide 13, and causing the two wave support rods 26 to unfold. When the wave support rods 26 unfold, the protrusions will continuously touch the protrusions 42, causing the inner pressing member 38 of the protrusions 42 to reciprocate to compress the third spring 37. Thus, under the movement of the wave support rods 26, the sand collection box 12 is driven to slide back and forth in the operating slide 13. During the up and down sliding process, it can continuously rub against the surface of the product. At this time, under the suction conveying in the guide tube 36, the sand adhering to the surface is sucked into the back suction pump 44, and then sucked into the transfer pump 11 through the connecting pipe 43, and discharged through the guide tube 36. During the process, the internal sand is discharged through the discharge hopper 7.

[0025] In a further technical solution, a stop bar 41 corresponding to the wave support rod 26 is fixedly connected to the outer surface of the cylinder 40. The protrusion 42 is interspersed with the cylinder 40. A transfer pump 11 is provided in the middle of each of the two operating slides 13. The upper and lower walls of the two transfer pumps 11 are connected to the connecting pipes 43. A suction pump 44 is provided on the inner side of each of the two sand collection boxes 12. The connecting pipes 43 are connected to the suction pumps 44. A guide tube 36 is provided on one side wall of the operating slide 13. Universal balls 10 are provided at the four corners of one side wall of each of the two operating slides 13. A baffle 33 is connected to one end of the wave guide plate 32. Sealing doors 4 are provided on both sides of the sandblasting machine body 1. A conveyor 6 is interspersed between the two sealing doors 4. A discharge hopper 7 is provided at the bottom of the sandblasting machine body 1.

[0026] This invention discloses a sandblasting device for the surface of enamel products, the specific working principle of which includes the following steps: The entire sandblasting device is started by personnel. The sandblasting machine body 1 is fed by the sand feeder 2, and then the sand is sprayed out through the spray gun 21. In specific operation, firstly, the universal ball 10 and the sand collection box 12 simultaneously come into contact with the outer surface of the product to be sandblasted. During sandblasting, the universal ball 10 rolls on the surface of the product. Then, depending on the size of the product, the slide 13 moves when it comes into contact, thereby driving the main strip 25 to slide and rotate on the surface of the fixed rod 46. During this process, the second spring 24 is compressed, thereby pushing the linkage strip 22 and the support frame 18 to move. At this time, the second spring 24 slides along the outer surface of the fixed rod 46. When the support frame 18 moves, it can also drive the auxiliary adjustment block 17 to move outside the spray gun 21. When the auxiliary adjustment block 17 moves, it drives the linkage seat 23 and the linkage block 34 to slide on the outer surface of the limiting rod 30. During the sliding of the linkage block 34, it drives the wave guide plate 32 to retract and fold inside the spray gun 21, and pulls the baffle 33 to move to replenish the opening 31. When the linkage seat 23 slides outside the limiting rod 30, it can drive the return plate 23 to move. Position rod 19 slides within U-shaped seat 35, further driving pressure plate 28 to compress first spring 20, thereby reducing the flow rate of sand and air sprayed from spray gun 21 by wave guide plate 32. When linkage plate 22 moves, it pushes the linkage plate 22 to move, causing transfer plate 15 to rotate on support frame 18, subsequently driving short rod 27 to move, causing pull plate 14 to move towards operating slide 13, and driving two wave support rods 26 to unfold. When wave support rods 26 unfold, the protrusions continuously interact with the protrusions. When the 42 contacts, the inner pressing part 38 of the protrusion 42 reciprocates and compresses the third spring 37, thereby driving the sand collection box 12 to slide back and forth in the operating slide 13 under the movement of the wave support rod 26. During the up and down sliding process, it can continuously rub against the surface of the product. At this time, under the suction conveying in the guide tube 36, the sand adhering to the surface is sucked into the suction pump 44, and then sucked into the transfer pump 11 through the connecting pipe 43, and discharged through the guide tube 36. During the process, the internal sand is discharged through the discharge hopper 7.
