This utility model solves the problem that the small plastic particles generated by the plastic product edge trimming machine are blown into the surrounding air because existing plastic product polishing machines do not have a dust removal mechanism.
[0004] This invention can prevent small plastic debris generated during the operation of the trimming machine from being blown into the surrounding air. However, the existing trimming machine, which fixes the plastic product in front of the grinder and grinds it statically, is a cumbersome process. At the same time, it cannot guarantee the uniformity of the grinding and trimming, which may result in the plastic product still having raised edges and poor grinding effect. Therefore, a plastic product trimming machine is proposed to solve the above-mentioned problems. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a plastic product edge trimming machine, which has advantages such as uniformly grinding the edges of plastic products, and solves the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A plastic product trimming machine includes a machine base and a frame, wherein the inner side of the frame is provided with a trimming component for uniformly grinding the edges of plastic products;
[0008] The trimming assembly includes a servo motor fixedly mounted on the right side of the frame. The output shaft of the servo motor is fixedly connected to a bidirectional lead screw.

A positioning frame is fixedly connected to the bottom of each movable block. A grinding motor is fixedly mounted on the inner side of the positioning frame. A trimming grinding head is fixedly connected to the output shaft of the grinding motor. A rotary motor is fixedly connected to the bottom of the machine base. A grinding table is fixedly connected to the output shaft of the rotary motor. A dust collection assembly is provided on the outside of the machine base to prevent dust accumulation.
[0009] Furthermore, the dust collection assembly includes a dust collection box fixedly connected to the left and right sides of the machine, an exhaust fan fixedly connected to the outside of the dust collection box, a connecting pipe fixedly installed on the top of the dust collection box, and a filter bag provided inside the dust collection box.
[0010] Furthermore, the exhaust pipe of the exhaust fan is connected to the dust collection box, and the connecting pipe is connected to the machine base.
[0011] Furthermore, the connecting pipe is made of stainless steel, and a dustproof net is installed on the outside of the exhaust fan.
[0012] Furthermore, a sealing plate is provided on the front of the dust collection box, and a magnetic sealing strip is adhered to the back of the sealing plate.
[0013] Furthermore, there are two movable rods, and the movable block is slidably connected to the movable rods.

[0015] Furthermore, a feeding tray is fixedly connected to the top of the grinding table, and the left and right sides of the feeding tray are threaded with fixing bolts for securing the plastic products.
[0016] Compared with the prior art, this utility model provides a plastic product trimming machine, which has the following beneficial effects:
[0017] 1. This plastic product trimming machine, through the setting of trimming components, includes a grinding motor that drives the trimming grinding head to rotate at high speed. During this process, a servo motor drives a bidirectional lead screw to rotate counterclockwise continuously. This causes two movable blocks to drive the grinding motor and the high-speed rotating trimming grinding head to approach the left and right edges of the plastic product for grinding and trimming. Subsequently, a rotary motor rotates the grinding table, thereby adjusting the orientation angle of the plastic product to continuously change the grinding position, ensuring the uniformity of grinding and trimming, and achieving the effect of uniformly grinding the edges of the plastic product.
[0018] 2. This plastic product trimming machine, by setting up a dust collection component, can suck up plastic dust particles that fall inside the machine into the dust collection box through the cooperation of the exhaust pipe and connecting pipe when grinding and trimming plastic products. The dust is then intercepted by the filter screen, thereby achieving the effect of collecting plastic dust particles. Attached Figure Description

Detailed Implementation
[0023] 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.
[0024] Please see Figures 1 to 3The plastic product trimming machine in this embodiment includes a machine base 1 and a machine frame 2. The inner side of the machine frame 2 is provided with a trimming component for uniformly grinding the edges of plastic products. The trimming assembly includes a servo motor 3 fixedly mounted on the right side of the frame 2. The output shaft of the servo motor 3 is fixedly connected to a bidirectional lead screw 4. Two movable blocks 5 are threaded onto the outer surface of the bidirectional lead screw 4. A movable rod 6 is fixedly connected to the inner side of the frame 2. A positioning frame 7 is fixedly connected to the bottom of the movable block 5. A grinding motor 8 is fixedly mounted on the inner side of the positioning frame 7. A trimming grinding head 9 is fixedly connected to the output shaft of the grinding motor 8. A rotary motor 10 is fixedly connected to the bottom of the machine base 1. A grinding table 11 is fixedly connected to the output shaft of the rotary motor 10. A dust collection assembly is provided on the outside of the machine base 1 to prevent dust accumulation. The grinding motor 8 can drive the trimming grinding head 9 to rotate at high speed. During this time, the servo motor 3 can drive the bidirectional lead screw 4 to rotate counterclockwise continuously, so that the two movable blocks 5 drive the grinding motor 8 and the high-speed rotating trimming grinding head 9 to approach the left and right edges of the plastic product for grinding and trimming.
[0025] Subsequently, the rotary motor 10 can rotate the grinding table 11, thereby adjusting the orientation angle of the plastic product to continuously change the grinding position, ensuring the uniformity of grinding and trimming, and achieving the effect of uniformly grinding the edges of the plastic product.
[0026] In this embodiment, the dust collection assembly includes a dust collection box 12 fixedly connected to the left and right sides of the machine base 1. An exhaust fan 13 is fixedly connected to the outside of the dust collection box 12, and a connecting pipe 14 is fixedly installed on the top of the dust collection box 12. A filter bag 15 is provided inside the dust collection box 12. When grinding and trimming plastic products, the exhaust fan 13 can suck plastic dust particles that fall into the inside of the machine base 1 into the dust collection box 12 through the cooperation of the exhaust pipe and the connecting pipe 14. The dust is then intercepted by the filter bag 15, thereby achieving the effect of collecting plastic dust particles.
[0027] It should be noted that the exhaust pipe of the exhaust fan 13 is connected to the dust collection box 12, and the connecting pipe 14 is connected to the machine base 1.
[0028] Specifically, the connecting pipe 14 is a stainless steel pipe, and the exhaust fan 13 is equipped with a dustproof net on the outside, which can prevent debris from being sucked into the interior of the exhaust fan 13.
[0029] It should be noted that a sealing plate 16 is provided on the front of the dust collection box 12, and a magnetic sealing strip is glued to the back of the sealing plate 16. The sealing plate 16 and the magnetic sealing strip ensure the airtightness of the dust collection box 12, and at the same time, they are easy to disassemble and assemble.
[0030] Specifically, there are two movable rods 6, and the movable block 5 is slidably connected to the movable rod 6. The movable rod 6 can limit the movable block 5 and prevent the movable block 5 from being driven by the bidirectional lead screw 4 to rotate together.
[0031] It should be noted that the machine base 1 is square in shape, while the grinding table 11 is circular in shape.
[0032] Specifically, the top of the grinding table 11 is fixedly connected to a feeding tray 17, and both sides of the feeding tray 17 are threaded with fixing bolts 18 for pressing against the plastic products. The feeding tray 17 and the fixing bolts 18 achieve the effect of pressing against the plastic products to prevent them from shifting.
[0033] The working principle of the above embodiments is as follows:
[0034] In use, the operator first places the plastic product into the loading tray 17, then rotates the fixing bolt 18 clockwise, causing the fixing bolt 18 to rotate clockwise inside the threaded hole, and finally presses its front end against the plastic product. After the plastic product is fixed, the grinding motor 8 and the servo motor 3 are started in sequence. The grinding motor 8 drives the trimming grinding head 9 to rotate at high speed. During this time, the servo motor 3 drives the bidirectional lead screw 4 to rotate counterclockwise continuously, so that the two movable blocks 5 drive the grinding motor 8 and the high-speed rotating trimming grinding head 9 to approach the left and right edges of the plastic product for grinding and trimming. Finally, the rotary motor 10 is started, which makes the grinding table 11 rotate, thereby adjusting the orientation angle of the plastic product to continuously change the grinding position and ensure the uniformity of grinding and trimming.
[0035] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that achieves the desired beneficial effect can be implemented. Furthermore, all electrical components in this embodiment are electrically connected to the main controller and power supply. The main controller can be a conventional, known device such as a computer that performs control functions. Those skilled in the art can control the electrical components through simple programming, and the existing disclosed power connection technologies are common knowledge in the field. Therefore, this embodiment will not elaborate further on their specific structural composition and working principles.
