[0002] Plastic woven bags are made primarily of polypropylene, which is extruded into film, slit into flat yarns, and then woven, braided, and bagged. Slitting typically involves cutting the film with a slitting blade in a slitting device. During slitting, rollers and other structures pull and move the film and flat yarns through the slitting blades.
[0003] When the wire slitting knife is in operation, wear is inevitable. After wear, maintenance is required, which requires stopping the production line and affecting the production of flat wire. At the same time, the wear of the wire slitting knife is uneven and its service life is limited. Utility Model Content

[0013] More preferably, the cutter roller is provided with prism-shaped fixed shafts on both sides, and fixed shaft sleeves are fitted on the fixed shafts. The outer side of the fixed shaft sleeve extends out of the mounting bracket and is provided with a corresponding locking plate. The locking plate is provided with a plurality of locking holes evenly distributed in relation to the mounting bracket.
[0014] Even more preferably, the plurality of locking holes are arranged in a ring with the axis of the cutter roller as the center.

Detailed Implementation
[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0030] Reference Figure 1-7 A slitting structure for processing woven fabric includes a cutter roller 1 and mounting brackets 2 on both sides of the cutter roller 1 for mounting the cutter roller 1. The cutter roller 1 has a mounting groove 12 on its annular sidewall, and a slitting mechanism 3 is provided in the mounting groove 12.
[0031] The slitting mechanism 3 includes a knife holder 31 disposed in the mounting groove 12, a plurality of slitting blades 33 evenly installed in the knife holder 31, and a locking assembly 34 disposed between the slitting blades 33 for fixing the slitting blades 33. The slitting blades 33 are fixedly installed by the knife holder 31. When slitting films of different specifications, the knife holder 31 with different spacing of slitting blades 33 can be replaced to meet the processing requirements of different flat yarns. The locking assembly 34 fixes the slitting blades 33, which facilitates the maintenance of the slitting mechanism 3.
[0032] The locking assembly 34 includes a locking block 341 disposed between the wire cutters 33, a pressing groove 343 disposed in the middle of the locking block 341, and a corresponding pressing block 344 disposed in the pressing groove 343. The pressing block 344 is provided with a locking hole 345 for locking it onto the cutter holder 31. The pressing groove 343 and the pressing block 344 are in the shape of a matching inverted trapezoid. The locking 341 can be made of hard rubber material. Bolts are used to press the pressing block 344 into the pressing groove 343 in conjunction with the locking hole 345, so that the locking block 341 is pressed to both sides to fix the wire cutter 33 between the locking blocks 341, ensuring the fixing effect of the wire cutter 33, and also facilitating replacement and maintenance after the wire cutter 33 wears out.
[0033] Based on the above technical solution, when slitting plastic film, the plastic film is driven through the cutter roller 1 by the conveyor roller, and then cut into flat filaments by the slitting blade 33. When maintenance of the slitting blade 33 is required, the locking block 341 can be removed to replace the slitting blade. When slitting different types of flat filaments, the blade holder 31 of different types can be replaced to ensure good compatibility for processing different types of flat filaments.
[0034] In this technical solution, such as Figure 1-7 As shown, the slitting blade 33 has an arc-shaped cutting edge 331, and multiple positioning holes 333 are provided at the blade heel. Positioning pins 342 are provided on both sides of the extrusion block 344 corresponding to the positioning holes 333. The arc-shaped cutting edge 331 ensures stable contact with the film, guaranteeing a good slitting effect. The positioning holes 333 fix the slitting blade 33, ensuring stable installation of the slitting blade 33 and guaranteeing the stability of slitting.
[0035] In this technical solution, such as Figure 1-3 As shown, multiple locking grooves 311 are evenly provided on both sides of the inner wall of the cutter holder 31 corresponding to the wire slitting cutter 33. Locking strips 332, matching the locking grooves 311, are integrally formed on both sides of the heel of the wire slitting cutter 33. Through the cooperation of the locking grooves 311 and the locking strips 332, the wire slitting cutter 33 is limited on both sides, ensuring the stability of the wire slitting cutter 33 in the left-right direction during wire slitting, ensuring uniform width of the flat wire, and guaranteeing good wire slitting quality.
[0036] In this technical solution, such as Figure 1-3 As shown, the annular sidewall of the cutter roller 1 is provided with two mounting grooves 12, each of which is equipped with a wire-splitting mechanism 3. By designing two sets of wire-splitting mechanisms 3, when one set of wire-splitting cutters 33 wears out, the other set of wire-splitting mechanisms 3 can be quickly replaced, ensuring the stable operation of the production line, facilitating maintenance, and increasing maintenance efficiency.
[0037] In this technical solution, such as Figure 1-3 As shown, the cutter roller 1 has prism-shaped fixed shafts 11 on both sides, and fixed bushings 21 are fitted on the fixed shafts 11. A mounting bracket 2 extends outward from the fixed bushing 21 and is correspondingly provided with a locking plate 211. Multiple locking holes 212 are evenly provided on the locking plate 211 corresponding to the mounting bracket 2. The multiple locking holes 212 are arranged in a ring around the axis of the cutter roller 1. The ring-shaped locking holes 212 facilitate adjustment of the installation angle of the cutter roller 1, thus facilitating the switching of the two slitting mechanisms 3. Simultaneously, by adjusting the angle of the cutter roller 1, different parts of the arc-shaped blade edge 331 of the slitting knife 33 can be made to contact the film, resulting in uniform wear of the slitting knife 33 and extending its service life.
[0038] When it is necessary to switch the wire cutting mechanism 3 or adjust the position of the blade 331, loosen the bolt in the locking hole 212 and adjust the angle of the locking plate 211 to drive the angle of the blade roller 1 to rotate. After the adjustment is completed, use the bolt to lock the locking hole 212 to ensure good switching efficiency, while ensuring the stability of the blade roller 1 and facilitating the installation and replacement of the blade roller 1.
[0039] In this technical solution, such as Figure 1-3 As shown, a limiting groove 121 is provided in the mounting groove 12, and a limiting strip 32 is provided on the inner side of the tool holder 31 corresponding to the limiting groove 121. The tool holder 31 is fixed by the cooperation of the limiting strip 32 and the limiting groove 121 to prevent the tool holder 31 from falling out. When it is necessary to remove the tool holder 31, it can be slid out from one side.
[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
