Technical Field
[0001] This utility model relates to the field of plastic shell polishing technology, and in particular to a polishing device for producing plastic shells. Background Technology
[0002] With the continuous development of plastic processing technology, plastic shells are widely used in various electronic products, home appliances and other fields. In order to improve the appearance quality and feel of the products, the surface of plastic shells usually needs to undergo fine grinding and polishing. Traditional polishing equipment often adopts a fixed grinding method, with the grinding disc fixed, which makes it impossible to fully conform to the curved surface of the plastic shell during the grinding process, resulting in uneven grinding and rough surface. This method not only affects the grinding quality, but also increases the frequency and difficulty of manual intervention and reduces production efficiency. With the increasing demand for automated production, a new polishing device is needed that can adapt to plastic shells of different shapes and sizes and achieve precise surface treatment during the grinding process to improve production quality and efficiency. Most existing plastic shell polishing equipment adopts a mechanized polishing structure. These structures typically use a rotating polishing disc to contact the shell surface and complete the surface smoothing process with the assistance of manual labor or robotic arms. In the existing technology, traditional polishing equipment has difficulty in achieving a tight fit with the surface of plastic shells, especially when facing complex curved surfaces. The polishing disc cannot make full contact with the plastic shell, resulting in poor polishing effect and low surface smoothness. Since the equipment cannot be effectively adjusted for shells of different shapes and sizes, uneven surface polishing is prone to occur during the polishing process, affecting the final product quality. Therefore, a polishing device for plastic shell production is proposed to solve the above problems. Utility Model Content
[0003] To overcome the above shortcomings, this utility model provides a polishing device for the production of plastic shells, which aims to improve the problem that traditional grinding equipment in the prior art cannot achieve close grinding with plastic shells and has low grinding smoothness.

[0005] This utility model has the following beneficial effects: 1. In this utility model, the sliding frame and sliding column are pushed to move inside the limiting frame by the output end of the electric telescopic rod, which in turn drives the motor to move.

[0009] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0010] Reference Figure 1 and Figure 2 The present invention provides an embodiment of a polishing device for producing plastic shells, comprising a support column 1, a support platform 2 fixedly connected to the top of the support column 1, a control console 3 fixedly connected to the top of the support platform 2, a triangular block 4 fixedly connected to the side wall of the support platform 2, an electric telescopic rod 7 fixedly connected to the top of the triangular block 4, and a sliding frame 6 fixedly connected to the output end of the electric telescopic rod 7. The electric telescopic rod 7 is used to drive the sliding frame 6 to move in the horizontal plane and adjust the position of the polishing disc 5 to adapt to plastic shells of different sizes.
[0011] A sliding assembly is provided on the top of the support platform 2. The sliding assembly is used to adjust the position of the polishing disc 5 to ensure the uniformity of polishing. The sliding assembly includes a sliding column 11 and a limiting frame 12. The bottom of the limiting frame 12 is fixedly connected to the top of the support platform 2. The sliding column 11 is slidably connected inside the limiting frame 12 and fixedly connected inside the sliding frame 6. The sliding cooperation of the sliding column 11 ensures the precise movement of the sliding frame 6. A motor 8 is fixedly connected inside the sliding frame 6. The output end of the motor 8 is fixedly connected to the polishing disc 5, which drives the polishing disc 5 to perform polishing operations on the plastic shell. A support rod 10 is fixedly connected to the top of the limiting frame 12. A hollow column 9 is fixedly connected to the top of the support rod 10. The hollow column 9 is slidably connected to the output end of the motor 8. The position of the polishing disc 5 is adjusted by sliding the hollow column 9, thereby adapting to different sizes and shapes of plastic shells. A clamping assembly is provided on the top of the support platform 2. The clamping assembly is used to fix the plastic shell, ensuring that the shell is stable and does not move during the polishing process, thus improving the polishing accuracy.
[0012] Specifically, after the plastic shell is securely fixed in the equipment, the electric telescopic rod 7 is activated. The output end of the electric telescopic rod 7 pushes the sliding frame 6 and the sliding column 11 to slide smoothly along a predetermined trajectory inside the limiting frame 12. As the sliding frame 6 moves, the sliding frame 6 and the sliding column 11 interact, driving the connected motor 8 and the polishing disc 5 to move synchronously. The motor 8 transmits power to the polishing disc 5 through its output end, causing the polishing disc to begin sliding along the predetermined trajectory. The output shaft of the motor 8 passes through the hollow column 9 and gradually moves forward, eventually driving the polishing disc 5 to gradually approach the surface of the plastic shell. During this process, the electric telescopic rod 7 and the sliding frame 6 work together to ensure that the polishing disc 5 can accurately and evenly adhere to the surface of the plastic shell for polishing, thereby effectively improving the surface smoothness and ensuring the uniformity and fineness of the polishing. Through this structural design, the equipment can flexibly adjust the degree of contact between the polishing disc and the shell surface, thereby achieving a highly efficient and precise polishing effect, solving the problem that traditional polishing equipment cannot fully adhere to the plastic shell, resulting in uneven polishing effects.
[0013] Reference Figure 3 and Figure 4The clamping assembly includes a slide rail 22 and a push column 21. The bottom of the slide rail 22 is fixedly connected to the top of the support platform 2. The push column 21 is slidably connected inside the slide rail 22. A clamping plate 23 is fixedly connected to one end of the push column 21 to fix the plastic shell during polishing and ensure its stability. A central column 13 is fixedly connected to the bottom of the support platform 2. A sliding ring 14 is slidably connected to the outer wall of the central column 13. The sliding ring 14 can slide along the central column 13 to provide support and stability. A crank 15 is rotatably connected inside the sliding ring 14. The crank 15 is used to transmit power to subsequent components. A connecting rod 17 is rotatably connected to one end of the crank 15. A crank 2 18 is fixedly connected to one end of the connecting rod 17. A notch frame 19 is rotatably connected to the outer wall of the crank 2 18. The function of the crank 2 18 is to drive the rotation belt... The moving clamping device is precisely adjusted to ensure that the clamping plate 23 can be properly fixed according to the size of the plastic shell. A hydraulic rod 16 is provided at the bottom of the crank 2 18. The hydraulic rod 16 is used to provide additional force to achieve the clamping action. The bottom of the hydraulic rod 16 is rotatably connected to one end of the crank 2 18. The bottom of the crank 2 18 is fixedly connected to the output end of the hydraulic rod 16. The clamping force can be adjusted as needed. A crank 3 20 is rotatably connected to the top of the crank 2 18. The function of the crank 3 20 is to further push the clamping action. One end of the crank 3 20 is rotatably connected to the inside of the push column 21, which drives the push column 21 to move forward, ensuring that the clamping plate 23 firmly fixes the plastic shell. The side wall of the notch frame 19 is fixedly connected to the outer wall of the support platform 2, which plays a stabilizing and guiding role, ensuring the smooth operation of the clamping assembly.
[0014] Specifically, when using the plastic shell polishing device, first place the plastic shell to be processed on the support platform 2, ensuring that the shell is stably in the predetermined position. Then, the operator starts the hydraulic rod 16. The output end of the hydraulic rod 16 drives the second crank 18 to move. The movement of the second crank 18 transmits power to the first crank 15 through the connecting rod 17, causing the first crank 15 to rotate. The rotation of the first crank 15 causes the sliding ring 14 to slide smoothly on the central column 13. At the same time, the offset of the second crank 18 will cause it to rotate to a certain extent within the notch frame 19, further pushing the third crank 20 to move. The displacement of the third crank 20 drives the push column. 21 slides forward, pushing column 21 to slide stably along slide rail 22. As pushing column 21 slides, clamping plate 23 is also driven synchronously. Clamping plate 23 moves towards the center of support platform 2, thereby firmly fixing the plastic shell placed above support platform 2, ensuring that the shell will not shift in position during polishing. Through this mechanical cooperation, the polishing device can automatically adjust the clamping force and position according to the different sizes and shapes of the plastic shell, ensuring that each plastic shell is evenly and firmly fixed during polishing, thereby avoiding the problem of uneven polishing caused by shell position shift, and further improving the accuracy and efficiency of polishing operation.
[0015] Working principle: When using the plastic shell polishing device, first place the plastic shell on the support platform 2, then start the hydraulic rod 16. The output end of the hydraulic rod 16 drives the second crank 18 to move. The movement of the second crank 18 drives the connecting rod 17 to move. At the same time, the connecting rod 17 drives the first crank 15 to rotate. The rotation of the first crank 15 drives the sliding ring 14 to slide on the central column 13. Meanwhile, the position of the second crank 18 shifts and rotates inside the notch frame 19. The rotation of the second crank 18 then drives the third crank 20 to move. The movement of the third crank 20 drives the push column 21 to move forward. The push column 21 moves along the slide rail 22. The upward sliding column 21 moves the clamping plate 23 towards the center of the support platform 2, thereby fixing the plastic shells of different sizes placed on the support platform 2. After the plastic shells are fixed, the electric telescopic rod 7 is activated. The output end of the electric telescopic rod 7 drives the sliding frame 6 and the sliding column 11 to slide inside the limit frame 12. The movement of the sliding frame 6 also drives the grinding disc 5 and the motor 8 to move. The output end of the motor 8 slides downward through the hollow column 9, while driving the grinding disc 5 to move towards the surface of the plastic shell, thereby achieving the effect of adhering and polishing the surface of the plastic shell.
