[0002] Plastic products are a general term for daily and industrial products made from plastic as the main raw material, including products made from all processes such as injection molding and blister molding. Plastic is a type of synthetic polymer material with plasticity. Together with synthetic rubber and synthetic fibers, it forms one of the three indispensable synthetic materials in daily life.

[0003] Plastic products are made of natural or synthetic resins as the main components, with various additives added. They can be molded into a certain shape under certain temperature and pressure conditions and keep the shape unchanged at room temperature. During the processing and use of plastic products, trimming operations may be required. However, the current plastic product processing generally adopts manual trimming, or a trimming disk is installed in front of the rubber mixing roller. Therefore, it is not convenient to trim according to the required width in actual use, and it is not convenient to trim accurately. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Reference Figure 1-Figure 3As shown, the trimming mechanism 3 includes a rotating rod 301 rotatably connected between two support frames 1, the rotating rod 301 is engraved with scale lines, and two moving rings 302 are slidably connected to the rotating rod 301, two sliders are symmetrically fixed inside the moving ring 302, two matching sliding grooves are provided at positions corresponding to the sliders on the rotating rod 301, the sliders are slidably connected in the sliding grooves, the moving rings 302 are threadedly connected with bolts 306, nuts are threadedly installed on the bolts 306, sleeves 303 are fixed to the moving rings 302, a fixed rod 304 is slidably connected inside the sleeve 303, a slitting disk 305 is rotatably connected to the fixed rod 304, a limiting mechanism 5 for adjusting the height of the fixed rod 304 is installed on the sleeve 303, an anti-deviating limiting strip is fixed on the fixed rod 304, and a limiting groove for matching use is provided on the inner wall of the sleeve 303. During the processing, the distance between the two movable rings 302 is adjusted according to the required width. When adjusting, the nut on the movable ring 302 is loosened, and then the bolt 306 is turned outward to move the position of the movable ring 302 on the rotating rod 301. Through the scale lines on the rotating rod 301, the slitting disk 305 can accurately control the width of the cutting edge, which is convenient for later processing.

[0026] Specifically, during the movement of the moving ring 302 , the moving ring 302 will not be rotated or deviated by means of the slider inside the moving ring 302 .

[0027] In this embodiment, refer to Figure 4-Figure 5 As shown, the limiting mechanism 5 includes a limiting cylinder 501 connected and installed on the sleeve 303, an arc-shaped limiting column 502 is movably connected inside the limiting cylinder 501, a plurality of arc-shaped grooves 503 used in conjunction with the limiting column 502 are opened on the fixing rod 304, a spring 2 504 is installed in the limiting cylinder 501, and the spring 2 504 is installed between the limiting column 502 and the inner wall of the limiting cylinder 501.

[0028] Specifically, when the trimming is completed, the slitting disk 305 has been in front of the rubber mixing roller 2, which will hinder the rubber mixing. At this time, the fixed rod 304 is pressed downward, and the limiting column 502 is subjected to the pressure of the fixed rod 304.
