Description

Technical Field

[0001] This utility model relates to the field of lampshade production, and in particular to a surface treatment device for aluminum parts of lampshades before spraying. Background Technology

[0002] The surface treatment device for aluminum lampshade parts before spraying is a surface pretreatment equipment. It uses high-pressure jet abrasive particles to impact the surface of aluminum parts, removing oxide layers, oil stains and burrs, forming a uniform rough texture, enhancing the adhesion and corrosion resistance of the sprayed coating, and ensuring that the subsequent sprayed coating is uniform in color and not easy to peel off. It is widely used for substrate cleaning and activation treatment before coating of metal parts such as lamps and decorative aluminum materials.

[0003] Existing surface treatment devices for aluminum lampshade parts lack surface pre-cleaning functionality. Without this function, loose deposits such as dry dust, sand, and fibers may remain on the lampshade surface, causing contaminants to embed into the sandblasted surface and affecting coating adhesion.

[0004] Therefore, given that the existing surface treatment devices for aluminum lampshade parts lack surface pre-cleaning capabilities and have deposits on the lampshade surface that cause contaminants to embed and affect coating adhesion, there is an urgent need to design a new type of surface treatment device for aluminum lampshade parts before coating. Utility Model Content

[0005] To overcome the problem that existing surface treatment devices for aluminum lampshade parts lack surface pre-cleaning function, and that the presence of deposits on the lampshade surface leads to contaminant embedding and affects coating adhesion.

[0006] The technical solution of this utility model is as follows: a surface treatment device for aluminum lampshade parts before spraying, including a main chamber; it also includes a conveyor belt and an installation platform. Transport troughs are provided at both ends of the main chamber. A conveyor belt is installed at the lower end of the transport trough. An installation platform is installed on the right side of the outer surface of the conveyor belt. A first motor is installed at the lower end of the installation platform. A first drive shaft is rotatably connected to the upper left side of the installation platform. The output end of the first motor is connected to the lower end of the first drive shaft. A first drive disc is installed at the upper end of the first drive shaft. A lifting frame is installed on the upper right side of the installation platform. A second motor is installed at the upper end of the lifting frame. A lead screw is rotatably connected inside the lifting frame. The output end of the second motor is connected to the upper end of the lead screw. A connecting plate is threaded onto the outer surface of the lead screw. A sponge brush is installed at the lower end of the connecting plate. A rotating support module is provided on the upper surface of the conveyor belt. When the first motor starts, it transmits power to the rotating support module through the first drive disc, driving the rotating support module to rotate. When the second motor starts, it drives the connecting plate and the sponge brush to move closer to or away from the installation platform.

[0007] Preferably, a first motor is provided, which drives the first transmission shaft to rotate. The rotation of the first transmission shaft drives the first active disc to rotate. When the rotating support module and the first active disc are in contact, the rotation of the first active disc drives the rotating support module to rotate, causing the lampshade placed on the rotating support module to rotate. A second motor is then provided, which drives the lead screw to rotate. The rotation of the lead screw restricts the rotation of the connecting plate through the lifting frame, thereby moving the connecting plate. The movement of the connecting plate moves the sponge brush, causing it to descend as the lampshade rotates, allowing the sponge brush to clean the lampshade surface around its circumference. After cleaning, the brush rises back to avoid affecting the normal operation of the conveyor belt. This achieves the purpose of pre-cleaning the lampshade surface, solving the problem that existing surface treatment devices for aluminum lampshade parts lack surface pre-cleaning functionality. Without this function, loose deposits such as dry dust, sand, and fibers may remain on the lampshade surface, causing contaminants to embed into the sandblasted surface and affecting coating adhesion.

[0008] Preferably, the rotating support module includes a bearing, a second drive shaft, a mounting base is installed at the upper end of the conveyor belt, a bearing is installed inside the mounting base, a second drive shaft is installed inside the bearing, a driven disc is sleeved on the outer surface of the second drive shaft, and a placement frame is installed at the upper end of the second drive shaft.

[0009] Preferably, an L-shaped plate is installed on the lower front side of the main compartment, and a third motor is installed on the upper part of the interior of the L-shaped plate. The output end of the third motor is connected to a transmission module.

[0010] Preferably, the transmission module includes a drive roller and a driven roller. The output end of the third motor is connected to the drive roller. The lower end of the main compartment is rotatably connected to a third transmission shaft. The lower end of the third transmission shaft is equipped with a driven roller. The outer surfaces of the drive roller and the driven roller are fitted with transmission belts. The upper end of the third transmission shaft is provided with an output module.

[0011] Preferably, the output module includes a second drive disk, and the upper end of the third drive shaft is equipped with the second drive disk. When the third drive shaft rotates, it drives the second drive disk to rotate. When the second drive disk rotates, it can drive the rotation support module.

[0012] Preferably, a mounting bracket is installed at the rear of the main compartment, a sand box is installed at the upper end of the mounting bracket, a centrifugal pump is installed at the upper end of the sand box, and a connecting module is provided at the upper end of the centrifugal pump. When the centrifugal pump is running, it drives the sand inside the sand box to be sprayed onto the surface of the lampshade through the connecting module.

[0013] Preferably, the connecting module includes a pipe and a nozzle. The upper end of the centrifugal pump is connected to the pipe, and the end of the pipe away from the mounting bracket is connected to the nozzle. During the output process, the sand is transported to the nozzle through the pipe.

[0014] The beneficial effects of this utility model are:

[0015] 1. Through the linkage design of the first motor, the first transmission shaft and the first active disc, the rotating support module and the lamp cover are driven to rotate stably, ensuring that the sponge brush can perform continuous and uniform cleaning action along the circumference of the lamp cover. This structure uses the principle of rotation and bonding transmission to avoid the lamp cover from shifting due to single-point force, thereby improving the cleaning coverage and surface treatment quality.

[0016] 2. Through the cooperation of the second motor, lead screw and lifting frame, the vertical movement trajectory of the connecting plate and sponge brush is precisely controlled. It can actively lower the brush body to achieve precise contact during cleaning and quickly reset and detach from the lamp cover after cleaning. This structure restricts the horizontal degree of freedom through mechanical limit to prevent positional deviation during lifting, ensures reliable operation and does not interfere with the conveyor belt, and ensures the smooth continuous operation of the equipment.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please see Figures 1-5 This utility model provides an embodiment of a surface treatment device for aluminum lampshade parts before spraying, including a main chamber 1; it also includes a conveyor belt 3 and an installation platform 4. The main chamber 1 has transport troughs 2 at both its left and right ends. A conveyor belt 3 is installed at the lower end of the transport trough 2. An installation platform 4 is installed on the right side of the outer surface of the conveyor belt 3. A first motor 5 is installed at the lower end of the installation platform 4. A first drive shaft 6 is rotatably connected to the upper left side of the installation platform 4. The output end of the first motor 5 is connected to the lower end of the first drive shaft 6. A first drive disc 7 is installed at the upper end of the first drive shaft 6. A lifting frame 8 is installed on the upper right side of the installation platform 4. A second motor 9 is installed at the upper end of the lifting frame 8. A lead screw 10 is rotatably connected inside the lifting frame 8. The output end of the second motor 9 is connected to the upper end of the lead screw 10. A connecting plate 11 is threaded onto the outer surface of the lead screw 10. A sponge brush 12 is installed at the lower end of the connecting plate 11. A rotating support module is provided on the upper surface of the conveyor belt 3. When the first motor 5 is started, the first drive... The disk 7 drives the rotating support module to rotate. When the second motor 9 starts, it drives the connecting plate 11 and the sponge brush 12 to move closer to or further away from the mounting platform 4. By setting the first motor 5, the first motor 5 drives the first transmission shaft 6 to rotate. When the first transmission shaft 6 rotates, it drives the first active disk 7 to rotate. When the rotating support module and the first active disk 7 are in contact, the rotation of the first active disk 7 drives the rotating support module to rotate, causing the lampshade placed on the rotating support module to rotate. Then, by setting the second motor 9, the second motor 9 drives the lead screw 10 to rotate. When the lead screw 10 rotates, the rotation of the connecting plate 11 is restricted by the lifting frame 8, thereby driving the connecting plate 11 to move. When the connecting plate 11 moves, it drives the sponge brush 12 to move, thereby lowering the sponge brush 12 when the lampshade rotates, so that the sponge brush 12 cleans the surface of the lampshade around the circumference. After cleaning, it rises back to avoid affecting the normal operation of the conveyor belt 3, thus achieving the purpose of pre-cleaning the surface of the lampshade.

[0025] Please see Figures 1-4In this embodiment, the rotating support module includes a bearing 14 and a second drive shaft 15. A mounting base 13 is installed on the upper end of the conveyor belt 3. The bearing 14 is installed inside the mounting base 13, and the second drive shaft 15 is installed inside the bearing 14. A driven disc 16 is sleeved on the outer surface of the second drive shaft 15. A placement rack 17 is installed on the upper end of the second drive shaft 15. The placement rack 17 is used to place and fix the lampshade. The driven disc 16, after contacting the first drive disc 7, transmits power to the second drive shaft 15, causing the placement rack 17 to rotate the lampshade. An L-shaped plate 18 is installed on the lower front side of the main compartment 1. A third motor 19 is installed on the upper end of the L-shaped plate 18. The output end of the third motor 19 is connected to a transmission module, which includes a drive roller 20 and a driven roller 22. The output end of the third motor 19 is connected to the drive roller 20. A third drive shaft 22 is rotatably connected inside the lower end of the main compartment 1. 1. A driven roller 22 is installed at the lower end of the third drive shaft 21. A transmission belt 29 is sleeved on the outer surface of the drive roller 20 and the driven roller 22. An output module is provided at the upper end of the third drive shaft 21. The output module includes a second drive disc 23. The second drive disc 23 is installed at the upper end of the third drive shaft 21. When the third drive shaft 21 rotates, it drives the second drive disc 23 to rotate. When the second drive disc 23 rotates, it can drive the rotation support module. By setting a third motor 19, the third motor 19 drives the drive roller 20 to rotate. When the drive roller 20 rotates, it drives the driven roller 22 to rotate through the transmission belt 29. When the driven roller 22 rotates, it drives the third drive shaft 21 to rotate. When the third drive shaft 21 rotates, it drives the second drive disc 23 to rotate. When it is in contact with the driven disc 16, it can transmit power to the driven disc 16 to make the lampshade rotate, thereby achieving the purpose of sandblasting the surface of the lampshade more comprehensively.

[0026] Please see Figures 1-5 In this embodiment, a mounting bracket 24 is installed at the rear end of the main chamber 1. A sand box 25 is installed at the upper end of the mounting bracket 24. A centrifugal pump 26 is installed at the upper end of the sand box 25. A communication module is provided at the upper end of the centrifugal pump 26. When the centrifugal pump 26 is running, it drives the sand inside the sand box 25 to be sprayed onto the surface of the lampshade through the communication module. The communication module includes a pipe 27 and a nozzle 28. The upper end of the centrifugal pump 26 is connected to the pipe 27. The end of the pipe 27 away from the mounting bracket 24 is connected to the nozzle 28. During the output process, the sand is transported to the nozzle 28 through the pipe 27. By setting up the centrifugal pump 26, when the centrifugal pump 26 is running, it pumps the sand inside the sand box 25 into the pipe 27, and then transports it to the nozzle 28 through the pipe 27. Finally, it is sprayed out through the nozzle 28, thereby achieving the purpose of sandblasting the lampshade.

[0027] During operation, the conveyor belt 3 is started by the external controller and the lamp cover is inserted into the placement rack 17. When the lamp cover moves to the position of the installation platform 4, the conveyor belt 3 stops running and the first motor 5 and the second motor 9 are started to make the lamp cover rotate and the sponge brush 12 is lowered for cleaning. After the cleaning is completed, the sponge brush 12 is raised and the conveyor belt 3 continues to run so that the lamp cover enters the main chamber 1. After entering, the conveyor belt 3 stops and the centrifugal pump 26 and the third motor 19 are started to make the lamp cover sandblasted during rotation. After the cleaning is completed, the conveyor belt 3 resumes operation and repeats the process.

[0028] Through the above steps, by installing the first motor 5, when the first motor 5 starts, it drives the first transmission shaft 6 to generate rotational motion. When the first transmission shaft 6 rotates, it synchronously drives the first active disk 7 to rotate. When the rotating support module and the first active disk 7 form a contact surface, the rotational power of the first active disk 7 will be transmitted to the rotating support module, causing the lampshade supported on the top of the rotating support module to rotate circumferentially. At the same time, the second motor 9 is configured as a drive source. When the second motor 9 runs, it drives the lead screw 10 to generate axial rotation. Utilizing the rotational constraint effect formed by the lifting frame 8 on the connecting plate 11, the rotational motion of the lead screw 10 is converted into the linear displacement of the connecting plate 11. When the connecting plate 11 moves along a straight trajectory, it synchronously pulls... The position of the sponge brush 12 is adjusted so that it presses down during the continuous rotation of the lampshade, ensuring that the cleaning surface of the sponge brush 12 completely covers the annular surface of the rotating lampshade. After the surface cleaning process is completed, the connecting plate 11 drives the sponge brush 12 to move in the opposite direction to the initial height, eliminating interference with the working space of the conveyor belt 3. This realizes the operation process of circumferential pretreatment of the outer surface of the lampshade, which solves the problem that the existing surface treatment device for aluminum parts of the lampshade lacks the function of surface pre-cleaning. Without the function of surface pre-cleaning, there may be loose attachments such as dry dust, sand particles, and fibers on the surface of the lampshade, which will cause contaminants to be embedded in the surface after sandblasting, affecting the adhesion of the coating.
