Description

Technical Field

[0001] This utility model belongs to the technical field of plastic flat wire processing, specifically, it relates to a plastic flat wire slitting structure. Background Technology

[0002] Shade nets are products that provide shade, sun protection, breathability, and wind protection. They are generally made from high-density synthetic fibers such as polyethylene and polypropylene, processed through drawing, weaving, and lamination. They possess a certain degree of toughness and wear resistance, and can withstand a certain amount of wind and ultraviolet radiation. The main equipment in the drawing process is a plastic flat film drawing machine, which typically includes a drawing main unit that heats and draws the polypropylene raw material into a plastic flat film, and a traction mechanism that pulls the plastic flat film and cuts it into filaments. During the drawing process, the plastic film is cut into filaments by a filament cutting device. Existing plastic strip filament cutting devices are not convenient for adjusting the blade spacing; when it is necessary to cut the plastic strip into strips of different widths, the entire blade needs to be replaced, making operation inconvenient.

[0003] In view of this, this utility model is proposed. Utility Model Content

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0026] like Figures 1 to 6As shown, a plastic flat wire slitting structure includes a slitting tool box 1 and a fixed mounting base 4. The slitting tool box 1 has through grooves 5 running through its upper and lower surfaces. Multiple tool mounting blocks 8 are arranged inside the slitting tool box 1. The upper and lower ends of the tool mounting blocks 8 extend outward from the through grooves 5. A side sliding groove 10 is provided on one side of the slitting tool box 1, and a side sliding groove 19 is provided on the other side. Side sliding blocks 11 and side sliding strips 12 are fixedly provided on both sides of the tool mounting blocks 8. A spacing adjustment block 13 is provided between adjacent tool mounting blocks 8. Flat wire slitting blades 9 are installed at the middle positions of the upper and lower surfaces of the tool mounting blocks 8. Slots are provided on both sides of the upper and lower surfaces of the tool mounting blocks 8. Mounting rods 16 are installed in the slots. A connecting spring 17 is installed between two adjacent mounting rods 16. A locking cap 18 is provided at the upper end of the mounting rod 16 to lock the mounting position of the connecting spring 17.

[0027] Among them, the size and specifications of the side sliding block 11 are adapted to the side sliding mating groove 10, and the size and specifications of the side sliding strip 12 are adapted to the side sliding mating groove 19. The side sliding mating groove 10 is a recessed groove structure, and the side sliding mating groove 19 is a through groove structure, to ensure the stability of the horizontal movement of the tool mounting block 8.

[0028] The slitting tool box 1 is provided with an adjustment plate 2 on the outside of the side sliding groove 19. The adjustment plate 2 has an insertion groove 3, which is a U-shaped opening groove structure for easy disassembly and replacement.

[0029] The width of the insertion groove 3 is compatible with the width of the side sliding groove 19. The cross-section of the spacing adjustment block 13 is an isosceles trapezoidal structure. A spacing adjustment stud 6 is provided on the outer side of the large end face of the spacing adjustment block 13. A spacing adjustment locking nut 7 and a locking sleeve 21 are installed on the spacing adjustment stud 6 to adjust and lock the position and state of the spacing adjustment block 13.

[0030] The two ends of the adjusting plate 2 are fixedly connected to the slitting tool box 1 by screws. The two ends of the slitting tool box 1 are respectively fixedly provided with mounting bases 4. The mounting bases 4 are L-shaped structures used for the fixed installation of the slitting tool box 1.

[0031] Both ends of the slitting tool box 1 are provided with threaded holes, and end rods 14 are installed in the threaded holes. One end of the end rod 14 located inside the slitting tool box 1 is provided with an end clamping seat 15 for adjusting the state by locking at both ends.

[0032] The relative position between the tool mounting block 8, located in the middle position, and the slitting tool box 1 is fixed. The mating surface of the tool mounting block 8 and the spacing adjustment block 13 is provided with an adjustment and mating inclined surface 20 to improve the stability of the adjustment support.

[0033] The working principle of this utility model is as follows: When the spacing of the flat wire slitting blades 9 needs to be adjusted, loosen the spacing adjustment locking nut 7 on the spacing adjustment stud, remove the adjustment mating plate 2, and fix an adjustment mating plate 2 of appropriate thickness on the slitting tool box 1. If the spacing between the flat wire slitting blades 9 is reduced, the end rod 14 does not need to be adjusted before adjustment. If the spacing between the flat wire slitting blades 9 is increased, the end rod 14 needs to be adjusted outward to avoid interference during the adjustment process. The connecting spring between the tool mounting blocks 8 When spring 17 is in a stretched state, the tool mounting block 8 moves towards the center position under the action of spring force during the adjustment of the spacing, ensuring effective contact between the tool mounting block 8 and the spacing adjustment block 13. The spacing adjustment locking nut 7 and the locking sleeve 21 are adjusted. The inner wall of the locking sleeve 21 is provided with an anti-slip pad, which can improve the locking state between the locking sleeve 21 and the spacing adjustment stud 6. Then, the end rod 14 drives the end clamping seat 15 to move, locking and limiting the outermost tool mounting block 8.

[0034] The spacing adjustment principle is based on the calculation method of the tangent function tanα. It is calculated by the trapezoidal base angle of the spacing adjustment block 13 section, and adjustment plates 2 with different thicknesses are set to adapt to different spacing adjustments.

[0035] The slitting tool box 1 of this utility model is provided with multiple tool mounting blocks 8. The tool mounting blocks 8 can move horizontally along the side sliding grooves on both sides of the slitting tool box 1. A spacing adjustment block 13 and a connecting spring 17 are provided between adjacent slitting tool boxes 1. The spacing between adjacent slitting tool boxes 1 can be adjusted by extending and retracting the spacing adjustment block 13. An adjustment mating plate 2 is provided on the outside of the slitting tool box 1. The adjustment mating plate 2 is provided with different thickness specifications. The adjustment mating plate 2 with the corresponding thickness specification can be replaced according to the adjustment needs to ensure the consistency of the adjustment state of the spacing adjustment block 13, thereby ensuring the consistency of the spacing between the flat wire slitting blades 9.

[0036] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
