[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] Depend on Figures 1 to 6 As shown, this utility model embodiment provides a longitudinal shearing edge wire take-up mechanism, including a bracket 1, a drive assembly 2, a rotating shaft 3, a take-up drum 4, a limiting assembly 5, and a friction assembly 6.

[0029] The rotating shaft 3 is rotatably mounted on the bearing 7 on the bracket 1, and there are two bearings 7; the take-up drum 4 is rotatably mounted on the rotating shaft 3 through two bearings 8.

[0030] Preferably, the drive assembly 2 is used to drive the rotating shaft 3 to rotate. The drive assembly 2 includes a geared motor 9, a chain 10 and two sprockets 11. The two sprockets 11 are respectively mounted on the output end of the geared motor 9 and the rotating shaft 3. The chain 10 is connected between the two sprockets 11 for transmission to drive the rotating shaft 3 to rotate.

[0031] Preferably, the friction assembly 6 includes an inner friction cam 12 and an outer friction cam 13 coaxially mounted on the rotating shaft 3. The inner friction cam 12 is fixedly connected to the take-up drum 4 by screws. The outer friction cam 13 is circumferentially fixedly connected to the rotating shaft 3. Specifically, in this embodiment, the circumferential fixation is achieved through a keyway connection, so that when the rotating shaft 3 rotates, it can drive the outer friction wheel to rotate. The keyway connection method is existing technology and will not be elaborated here. Thus, by adopting an outer loose and inner tight design for the inner friction cam 12 and an inner tight and outer loose design for the outer friction cam 13, and with their friction ends rotating against each other, a friction pair is formed. This friction pair converts the constant rotational speed of the rotating shaft 3 into a variable rotational speed for the take-up drum 4. When the tension of the take-up drum 4 changes during edge wire take-up, constant linear speed winding can be achieved.

[0032] Furthermore, the friction assembly 6 also includes a compression spring 14, a pressure cap 15, and an adjusting nut 16. The outer friction wheel and the rotating shaft 3 are connected via a keyway, allowing for axial relative sliding. The compression spring 14 is positioned between the outer friction wheel and the pressure cap 15. The adjusting nut 16 is threaded onto the rotating shaft 3 and abuts against the end of the pressure cap 15 away from the compression spring 14. The compression spring 14, mounted on the outer side of the outer friction cam 13, has its preload adjusted by the adjusting nut 16. When the diameter of the edge wire on the take-up drum 4 increases, the elastic deformation of the compression spring 14 automatically compensates for the change in friction, thereby maintaining a dynamic match between the rotational speed of the take-up drum 4 and the production line speed.

[0033] Furthermore, the take-up drum 4 is a frustum structure with a diameter that gradually decreases from the inside to the outside, which is suitable for quick unloading after the edge wires are collected.

[0034] The take-up drum 4 has multiple evenly spaced openings 17 around its circumference; in this embodiment, four openings are provided. During take-up, the tip of the edge wire is directly inserted into the opening 17 to begin winding. The trimming speed of the production line is constant. After the position pressure of the compression spring 14 is adjusted by the adjusting nut 16, the outer friction cam 13 drives the inner friction cam 12 and the drum to rotate through friction. At this time, the three are almost synchronized. As the diameter of the edge wire on the take-up drum 4 increases, its linear speed accelerates. At this time, the take-up drum 4's tendency to rotate faster will attempt to overcome the friction between it and the outer friction cam 13. When this accelerating torque exceeds the preset friction torque, slippage will occur between the friction surfaces. The outer friction cam 13 continues to rotate at a constant speed, while the rotation speed of the inner friction cam 12 and the take-up drum will decrease. After the rotation speed decreases, the linear speed of the take-up drum 4 also decreases, returning to a constant speed state that matches the trimming speed of the production line. Slippage will continue to occur, and the rotation speed of the drum is dynamically adjusted to ensure that the edge wire is automatically tightened without breaking due to excessive tension.

[0035] Preferably, the limiting component 5 includes an inner baffle 18 and an outer baffle 19, which are respectively fixed to both ends of the take-up drum 4 by screws, so as to concentrate the edge threads on the take-up drum 4 during take-up.

[0036] In this embodiment, the outer baffle 19 is fixed by two screws, one above the other. Two butterfly holes 20 for installing screws are provided on the outer baffle 19 at the positions corresponding to the screws. During unloading, after the two screws are loosened, the outer baffle 19 can be rotated and slid into the butterfly holes 20 without needing to be removed, thus saving disassembly time.

[0037] Preferably, in order to reduce weight, the inner baffle 18 and the outer baffle 19 are provided with a plurality of weight-reducing holes 21 evenly distributed around their circumferences.

[0038] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
