[0021] Specifically, mounting plates 401 are movably provided outside both sides of the bidirectional screw rod 202 , and the mounting plates 401 and the bidirectional screw rod 202 are connected by threaded connection.

[0022] In this embodiment, by setting a bidirectional screw rod 202 and a mounting plate 401, when the bidirectional screw rod 202 rotates, the mounting plate 401 moves on the surface of the bidirectional screw rod 202 as the bidirectional screw rod 202 rotates, so that the spacing between the mounting plates 401 on both sides is consistent with the width of the rolled rubber.

[0023] Specifically, a blade 402 is fixedly disposed on the rear portion of the mounting plate 401 .

[0024] In this embodiment, blades 402 are provided, and the blades 402 are respectively located on both sides of the rubber. When the rubber is rolled up, the blades 402 on both sides work synchronously to accurately cut the sides of the rubber, ensuring that the rubber remains flat during the rolling process, thereby improving the accuracy and consistency of the rubber products.

[0025] Specifically, a sliding rod 403 is movably provided inside the front part of the mounting plate 401, and the connection relationship between the sliding rod 403 and the mounting plate 401 is a sliding connection.

[0026] In this embodiment, by setting the sliding rod 403, since the sliding rod 403 is slidably connected to the mounting plate 401, the sliding rod 403 provides stable support and guiding effects, so that the mounting plate 401 can slide smoothly along the direction of the sliding rod 403, thereby preventing the mounting plate from shifting or shaking during movement.

[0027] Specifically, support columns 404 are fixedly provided at the four corners of the bottom of the base 1 , and anti-skid rubber pads 405 are fixedly provided at the bottom of the support columns 404 .

[0028] In this embodiment, by providing a support column 404 and an anti-slip rubber pad 405, the support column 404 bears the weight of the entire trimmer, and the provision of the anti-slip rubber pad 405 can effectively prevent the trimmer from sliding due to vibration or external force, thereby ensuring the stability and safety of the trimmer. At the same time, the anti-slip rubber pad 405 can also absorb and disperse the vibration generated during the operation of the trimmer, thereby reducing the impact of noise and vibration on the working environment and surrounding personnel, and improving work comfort.

[0029] Specifically, a dust collecting groove 406 is provided in the middle of the top of the base 1 .

[0030] In this embodiment, a dust collecting trough 406 is provided, and the dust collecting trough 406 is located below the blade 402, so as to ensure that the rubber burrs cut by the blade 402 can directly fall into the inside of the dust collecting trough 406, and the dust collecting trough 406 collects these wastes for easy processing by the staff.

[0031] When in use, the pull ring 306 is pulled, and the annular clamping plate 303 moves toward one side of the pull ring 306 under the drive of the limiting rod 305, and squeezes the reset spring 304. When one end of the limiting rod 305 moves out of the through hole 204, the restriction of the rotating handle 203 is released. At this time, the rotating handle 203 can be rotated to adjust the distance between the mounting plates 401 so that the distance between the blades 402 on both sides is consistent with the width of the rubber to be trimmed. After the adjustment is completed, the pull ring 306 is released, and the reset spring 304 is released. Under the action of force, the annular clamping plate 303 slides inside the installation box 302 toward the side away from the pull ring 306, while driving one end of the limiting rod 305 to pass through the through hole 204, thereby limiting the turning handle 203 and improving the stability of the blade 402. During the winding process, with the cooperation of the pressure roller and the turning roller, the wound rubber maintains stable transportation, and the blade 402 will cut the excess burrs on the side of the wound rubber, so that the wound rubber can be trimmed flexibly and stably, thereby enhancing the trimming effect of the trimming machine.

[0032] In summary, the trimming machine for precision rubber and plastic processing is provided with an L-shaped block 301, an installation box 302, an annular clamping plate 303, a reset spring 304, a limiting rod 305 and a pull ring 306. When the pull ring 306 is pulled, the limiting rod 305 drives the annular clamping plate 303 to move and squeezes the reset spring 304. When one end of the limiting rod 305 moves out of the through hole 204, the restriction of the rotating handle 203 is released. At this time, the rotating handle 203 can be rotated to adjust the distance between the blades 402 on both sides. The operation is convenient, which improves the convenience of the trimming machine for precision rubber and plastic processing. After the adjustment is completed, the pull ring 306 is released. Under the elastic force of the reset spring 304, the annular clamping plate 303 moves away from the pull ring 30 in the installation box 302. When one side of 6 slides, it drives one end of the limiting rod 305 to pass through the through hole 204, so as to limit the rotating handle 203 and avoid the self-rotation of the bidirectional screw rod 202, thereby improving the stability of the blade 402, enhancing the trimming effect, and improving the performance of the trimming machine for precision rubber and plastic processing. By arranging the anti-skid rubber pad 405, the anti-skid rubber pad 405 can effectively prevent the trimming machine from sliding due to vibration or external force during operation, thereby ensuring the stability and safety of the trimming machine. The rubber material also has certain elasticity and buffering performance, so that the anti-skid rubber pad 405 can absorb and disperse the vibration generated during the operation of the trimming machine, thereby reducing the impact of noise and vibration on the working environment and surrounding personnel, and improving working comfort.
