DETAILED DESCRIPTION

[0017] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings.

[0018] like Figure 1-5As shown, a display stand surface sandblasting treatment device comprises a box body 1, a box door 2 is arranged on one side of the box body 1, a material receiving hopper 3 is arranged at the lower end of the box body 1, a rolling assembly is arranged inside the box body 1, the rolling assembly comprises a gear ring 4 symmetrically arranged inside the box body 1, gear groups 5 for supporting and limiting the gear ring 4 are arranged on both sides of the inside of the box body 1, a first motor 6 for driving the gear group 5 to rotate is arranged on the outer surface of the box body 1, a circular ring 7 is arranged inside the gear ring 4, guide rods 8 are symmetrically arranged inside the circular ring 7, and two placement nets 9 are also included, the two groups of placement nets 9 are located inside the gear ring 4 and are slidably connected to the guide rod 8, a limiting rod 10 is arranged on one side of the placement net 9, and the limiting rods 10 on the two groups of placement nets 9 are arranged relatively A bidirectional screw rod 11 is arranged on one side of the ring 7, and two placement nets 9 are both threadedly connected with the bidirectional screw rod 11. A second motor 12 for driving the bidirectional screw rod 11 to rotate is also arranged on the ring 7. A side box 13 is arranged on one side of the box body 1, and a placement rack 14 is arranged inside the side box 13. A plurality of sleeves 15 are arranged inside the placement rack 14, and a sandblasting tube 16 is arranged at one end of the sleeve 15. A sandblasting nozzle 17 is arranged on the sandblasting tube 16, and a conveying pipe 18 connected to the sandblasting tube 16 is arranged inside the sleeve 15. A fixed plate 19 is arranged on one side of the sandblasting tube 16, and the sleeve 15 is rotatably connected to the fixed plate 19. A first electric telescopic rod 20 is arranged on the placement rack 14, and the output end of the electric telescopic rod is fixedly connected to the fixed plate 19.

[0019] A track 25 is provided on the outer surface of the box body 1, and the box door 2 slides in the track 25. The outer surface of the box door 2 is symmetrically provided with handles 26. The handles 26 are convenient for controlling the movement of the box door 2. When the box door 2 is made of transparent material, it is convenient to observe the processing status of the display bracket 21 on the placement net 9.

[0020] The receiving hopper 3 is used to collect materials dropped during sandblasting to facilitate the reuse of materials. A sealing cover 28 is provided at the lower end of the receiving hopper 3. The sealing cover 28 is snap-fitted to the receiving hopper 3 or connected to the receiving hopper 3 by bolts. When the sandblasting materials in the receiving hopper 3 need to be taken out, the sealing cover 28 can be opened.

[0021] The height of the fixed limit rod 10 on the placement net 9 is set according to the height of the display bracket 21. When the display bracket 21 is placed on the placement net 9, the height of the display bracket 21 when it is laid flat is slightly less than the sum of the heights of the two limit rods 10. The display bracket 21 can be clamped on the placement net 9 through the limit rod 10. The high-speed sandblasting material sprayed by the sandblasting nozzle 17 cannot cause the display bracket 21 on the placement net 9 to shake significantly. When the sandblasting stops, the display bracket 21 can be restored to the state just placed on the placement net 9. After one side of the display bracket 21 is processed, the bidirectional wire is driven by the second motor 12. The rod 11 rotates, and the two placement nets 9 on the bidirectional screw rod 11 approach each other until the limit rods 10 on the two placement nets 9 abut against each other, and then the second motor 12 stops working, and then the first motor 6 is controlled to start, and the first motor 6 drives the gear ring 4 to rotate through the gear set 5, and the gear ring 4 drives the ring 7 to rotate, and then drives the two placement nets 9 on the ring 7 to rotate. When the two placement nets 9 rotate 180°, the first motor 6 stops working. At this time, the other side of the display bracket 21 faces upward, and then the second motor 12 is controlled to reverse, so that the two placement nets 9 move away from each other, so as to facilitate sandblasting of the untreated surface of the display bracket 21.

[0022] The gear set 5 includes four gears, which are rotatably connected to the inner wall of the housing 1 and are all in external meshing with the gear ring 4. The central angle between two adjacent gears is 90°.

[0023] Through the clamping of the two placement nets 9 and the limiting of the limiting rods 10 , the display bracket 21 located on one of the placement nets 9 can be stably flipped onto the other placement net 9 .

[0024] When turning over the display bracket 21, it is necessary to first withdraw the sandblasting tube 16 from between the two placement nets 9 to prevent obstruction to the rotation of the placement nets 9. Specifically, start the first electric telescopic rod 20, which drives the fixed plate 19 to move toward the direction close to the side box 13. The fixed plate 19 also drives the sandblasting tube 16 and the sleeve 15 to move toward the side box 13, so that the sandblasting tube 16 can be completely withdrawn from the range of rotation required by the placement net 9, thereby ensuring that the placement net 9 can complete the flipping action.

[0025] The delivery pipe 18 is connected to an external sandblasting machine.

[0026] Furthermore, a bracket 21 is provided on the lower surface of the sleeve 15, and also includes a cross bar 22 for connecting multiple brackets 21. The cross bar 22 is hinged to the bracket 21. A second electric telescopic rod 23 is provided on the fixed plate 19. Two limit blocks 24 are provided at the output end of the second electric telescopic rod 23. One of the brackets 21 is located between the two limit blocks 24. When the output end of the second electric telescopic rod 23 cyclically extends and retracts, it can drive the two limit blocks 24 to move. The two limit blocks 24 can drive the bracket 21 matched with it to move forward and backward, thereby controlling the cross bar 22 to move forward and backward. At the same time, the cross bar 22 can also move up and down, thereby controlling the sleeve 15 to swing back and forth, so that the sandblasting tube 16 and the sandblasting nozzle 17 swing back and forth, which can increase the working range of the sandblasting nozzle 17 and improve the sandblasting efficiency and sandblasting effect.

[0027] Furthermore, a storage plate 27 is provided inside the box body 1 and on one side of the box door 2. When placing the display stand 21 on the placement net 9, the display stand 21 can be placed on the storage plate 27 first, which is convenient for the subsequent placement of the display stand 21. There is no need to repeatedly take the display stand 21 from the outside, thereby improving the convenience of placing the display stand 21.

[0028] Working principle: first, the display bracket 21 is placed on the placement net 9, and then the display bracket 21 on the placement net 9 is sandblasted by the sandblasting nozzle 17. After the upper surface of the display bracket 21 is sandblasted, the sandblasting nozzle 17 stops sandblasting, and then the sandblasting tube 16 is driven to withdraw from between the two placement nets 9 by the first electric telescopic rod 20. Then the first electric telescopic rod 20 stops working, and then the second motor 12 is controlled to work. The second motor 12 drives the two placement nets 9 to approach each other and clamp the display bracket 21 located on the lower placement net 9. When the two placement nets 9 complete the alignment, the display bracket 21 is clamped. After the display bracket 21 is clamped, the second motor 12 stops working and then controls the first motor 6 to work. The first motor 6 drives the ring gear 4 to rotate through the gear set 5. When the ring gear 4 rotates 180°, the display bracket 21 is turned over, the first motor 6 stops working, and then the second motor 12 controls the two placement nets 9 to move away from each other until the sandblasting tube 16 can enter between the two placement nets 9. Then the second motor 12 stops working, and then drives the sandblasting tube 16 to enter between the two placement nets 9 through the first electric telescopic rod 20 to sandblast the other surface of the display bracket 21.

[0029] After the device completes the sandblasting treatment on one side surface of multiple display brackets 21, all the display brackets 21 can be turned over uniformly, without the need for staff to turn over the display brackets 21 one by one, which greatly improves the turning efficiency of the display brackets 21, saves manual operation time, and improves the sandblasting efficiency.
