Technical Field
[0001] This utility model relates to the field of plastic product manufacturing technology, specifically to a trimming device for plastic products. Background Technology
[0002] Plastic products are a general term for everyday and industrial goods made primarily from plastics. This includes products manufactured using processes such as injection molding and thermoforming. Plastics are a class of synthetic polymer materials with malleability. Together with synthetic rubber and synthetic fibers, they form the three essential synthetic materials for daily life. Specifically, plastics are materials made primarily of natural or synthetic resins, with various additives, which can be molded into specific shapes under certain temperature and pressure conditions and retain their shape at room temperature.
[0003] During the manufacturing process of plastic products, rough edges often form at the corners, affecting the appearance of the products. Therefore, these rough edges need to be repaired and removed. When the trimming device trims the rough edges of the plastic products, it generates a large amount of plastic powder, which accumulates on the trimming device and is difficult to clean and collect.
[0004] Therefore, it is necessary to design a trimming device for plastic products to improve the above-mentioned problems. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model designs an edge-trimming device for plastic products.

[0028] Example:
[0029] This utility model provides a trimming device for plastic products, which aims to solve the technical problem that a large amount of plastic powder generated during the trimming of plastic products accumulates on the trimming device and is inconvenient to clean and collect.
[0030] Please see Figures 1-4 This embodiment provides a trimming device for plastic products, including a processing table 1. A controller is installed on the outside of the processing table 1. The controller is electrically connected to an electrical control device via a wire to control the operation of the electrical control device. A pair of limiting slide grooves 101 are provided on the top of the processing table 1. Two sets of electric push rods 102 are installed on one side of the top of the processing table 1. A dust collection hood 103 is fixedly connected to the side of the processing table 1 away from the electric push rods 102. The dust collection hood 103 prevents powder from splashing everywhere. A dust collection tray 104 is slidably connected to one side of the processing table 1 and inside the dust collection hood 103. The dust collection tray 104 collects plastic powder in a concentrated manner for easy subsequent cleaning.
[0031] Please refer to Figure 1 and Figure 2 An electric push rod 102 is fixedly connected to a mounting platform 2 on the side corresponding to the dust collection hood 103. The electric push rod 102 pushes the mounting platform 2 to move and adjust as a whole. On both sides of the bottom of the mounting platform 2, and at positions corresponding to the limiting slide groove 101, directional pulleys are rotatably connected. The mounting platform 2 is slidably connected to the limiting slide groove 101 through the directional pulleys, which improves the smoothness of the movement of the mounting platform 2. A powerful fan 201 is installed on the side of the mounting platform 2 corresponding to the electric push rod 102. The powerful fan 201 blows the plastic powder generated by the grinding wheel 603 during burr repair into the dust collection hood 103, preventing the plastic powder from accumulating on the trimming table 3. A motor 202 is installed at the center of the bottom of the mounting platform 2.
[0032] For further details, please refer to Figure 1 , Figure 2 and Figure 4A trimming table 3 is installed above the motor 202 on the top of the mounting platform 2. The motor 202 drives the trimming table 3 to rotate, facilitating trimming of other sides of the plastic product.

The clamping component 404 is bolted to the end of the electric push rod 403 away from the rotating shaft 4021. An anti-slip pad is fixedly connected to one side of the push rod 3 403. The anti-slip pad improves the stability of the clamping component 404. The clamping component 404 is bolted to the electric push rod 3 403, which makes it easy to replace the clamping component 404 with a clamping end shape that matches the shape of the plastic product according to the structural requirements of the plastic product. This allows the clamping component 404 to provide stable clamping and fixing of the plastic product. The electric push rod 2 401 drives the plastic product to adjust its height, so that the plastic product fits against the grinding wheel 603 for edge trimming. The motor 2 indirectly drives the plastic product to rotate, so as to repair the burrs in different positions. The motor 2 is installed on the right side of the connecting block 402 away from the electric push rod 3 403. A dust cover 405 is installed on the outside of the motor 2 to protect the motor 2.

The movable rack 601 is slidably connected to the limiting slide groove 501 via the limiting slider 6011. The two sets of movable racks 601 are respectively meshed on the left and right sides of the gear disk 503. The bottom ends of the two sets of movable racks 601, at opposite ends, are fixedly connected to... A horizontal moving device 602 is connected, and a grinding wheel 603 is installed at the bottom of the horizontal moving device 602. The horizontal moving device 602 drives the grinding wheel 603 to move back and forth to adjust the repair position. The motor 3 502 drives the gear disk 503 to rotate, so that the two sets of moving racks 601 mesh synchronously with the two sides of the gear disk 503. Through the limit slider 6011, it is slidably connected to the limit slide groove 2 501, which drives the horizontal moving device 602 to adjust the spacing according to the size of the plastic product, so that the grinding wheel 603 can fit against the rough edge for repair.
[0035] In addition, it should be noted that the controller, electric push rod, powerful fan 201, horizontal moving device 602 and grinding wheel 603 are all existing technologies, and their internal working principles and operation procedures will not be described in detail here.
[0036] The working process of this utility model is as follows: First, the plastic product is placed on the trimming table 3. According to the structural requirements of the plastic product, the clamping end shape of the clamping component 404 is replaced and bolted to the electric push rod 403 to provide stable clamping and fixing of the plastic product. The electric push rod 102 pushes the mounting table 2 to the dust collection hood 103. The mounting table 2 is slidably connected to the limiting slide groove 101 via a directional pulley, improving the smoothness of the movement of the mounting table 2. The electric push rod 201 adjusts the height of the plastic product to fit the height of the grinding wheel 603. The motor 302 drives the gear disk 503 to rotate, causing the two sets of moving racks 601 to rotate. The two sides of the synchronous gear disk 503 mesh with each other, and the limit slider 6011 slides and the limit slide groove 501. The horizontal moving device 602 is driven to adjust the spacing according to the size of the plastic product, so that the grinding wheel 603 can fit against the burrs for repair. The powerful fan 201 blows the plastic powder generated by the grinding wheel 603 for burr repair into the dust collection hood 103 to prevent the plastic powder from accumulating on the trimming table 3. The dust collection tray 104 collects the plastic powder for easy cleaning later. The second motor indirectly drives the plastic product to rotate, so as to repair the burrs on different corners. The first motor 202 drives the trimming table 3 to rotate, so as to trim other sides of the plastic product.
[0037] The entire operation process is simple and convenient. Compared with existing plastic product trimming devices, this utility model is designed to facilitate the cleaning and collection of plastic powder generated during trimming, improve the adjustability of plastic product trimming, and enhance overall practicality.
