Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of textile machinery, in particular to a stable wire-stretching mechanism of a wire winding machine. Background Art
[0002] The winding machine, also known as the bobbin winder or yarn winding machine, is one of the equipment for post-spinning and preparation engineering. The main purpose of the winding machine is to rewind the bobbin yarn from the twisting machine or the spinning machine into a larger bobbin. The winding machine is a common winding equipment for production in the wire making industry. The tensioning frame is an accessory on the winding machine, which is responsible for managing and controlling the tension of the yarn during the winding process. The main goal of the tensioning mechanism is to ensure that the yarn passes through the winding machine with a constant and appropriate tension, so as to maintain the stability of the yarn quality and the consistency of the processing process. The tensioning mechanism plays a vital role in the winding process. If the yarn tension is too large, it may cause the yarn to break and affect the production efficiency; if the tension is too small, it may cause the yarn to relax and affect the quality of subsequent processing. Some tensioning mechanisms need to penetrate the end of the yarn from the inside, and during the adjustment process, the yarn breaks and needs to be re-inserted, which is relatively cumbersome, so improvements are made based on this.

DETAILED DESCRIPTION

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] See also Figure 1-6 The utility model provides a technical solution: a stable wire-stretching mechanism of a wire-winding machine, comprising a wire-stretching unit 1, wherein the wire-stretching unit 1 comprises:
[0026] The operating part 13 can be rotated and lifted upward;
[0027] The operating part 2 4 is arranged in cooperation with the operating part 1 3 . A fastening bolt 46 is arranged at the front end of the operating part 2 4 . The fastening bolt 46 controls the magnitude of the rotational friction force of the operating part 2 4 . The operating part 1 3 and the operating part 2 4 squeeze the yarn.
[0028] The wire-stretching unit 1 also includes a cross 2, and two oppositely arranged bayonet holes 23 are opened at the front end of the cross 2. A control ring 24 is clamped in the bayonet hole 23. The outer side of the control ring 24 is fixed to the operating part 3. The operating part 4 is arranged at the axis of the control ring 24, so that the position of the operating part 4 is relatively fixed. The position of the outer operating part 3 is changed, and the yarn can be clamped.
[0029] The operating part 13 includes an extrusion wheel 31, a support frame 34 is fixed on the outer side of the control ring 24, a connecting shaft 32 that can move up and down is clamped on the inner side of the support frame 34, a clamping opening 33 is opened on the outer wall of the connecting shaft 32, the clamping opening 33 is clamped with the support frame 34, and a telescopic shaft 35 is fixed between the connecting shaft 32 and the support frame 34. The telescopic shaft 35 can be telescopically arranged, and a spring for reset is provided inside. Under the action of the spring, the telescopic shaft 35 squeezes the connecting shaft 32, so that the extrusion wheel 31 and the matching layer 43 are squeezed;
[0030] The extrusion wheel 31 is sleeved onto the end of the connecting shaft 32 .
[0031] The operating part 2 4 includes two opposite control half layers 41, and the opposite surfaces of the two half control half layers 41 are both provided with matching layers 43. The two half control half layers 41 are arranged to cooperate with each other. A control shaft 42 is fixed on one side of the cross 2, and the two half control half layers 41 are both sleeved on the control shaft 42. The extrusion wheel 31 is squeezed with the matching layer 43 between the two half control half layers 41, and the extrusion wheel 31 is fitted with the control half layers 41 on both sides. An extrusion sheet 44 is provided on the outer surface of the outer control half layer 41, and the extrusion sheet 44 is sleeved to the end of the control shaft 42, and a fastening bolt 46 is provided on the outer side of the extrusion sheet 44, and the fastening bolt 46 is threadedly connected to the control shaft 42. A control spring 45 is fixed between the extrusion sheet 44 and the fastening bolt 46, and the friction effect of the extrusion sheet 44 on the control half layer 41 is achieved by rotating the fastening bolt 46.
[0032] The outer side of the matching layer 43 is circular, and its end face is concave and convex, and the concave and convex surfaces of the matching layers 43 on both sides are matched. Even if the two half control half layers 41 are in a loose state, the matching layers 43 on both sides can still be matched to avoid the yarn being clamped between the two matching layers 43 and avoid jamming.
[0033] A circular hole 21 is also provided on the end face of the cross 2, in which a metal ball is placed. A limiting bolt 22 is fixed at one end of the circular hole 21, and the metal ball is squeezed against the inner control half layer 41. The inner control half layer 41 is squeezed against the metal ball to realize the rotation of the metal ball, which can minimize friction and avoid jamming.
[0034] When in use, the squeezing wheel 31 is lifted upward, so that the telescopic shaft 35 is squeezed upward, and the squeezing wheel 31 moves upward, and then the yarn is squeezed inward from the outside of the squeezing wheel 31, so that the yarn is clamped between the squeezing wheel 31 and the two control half layers 41, and then under the pushing action of the telescopic shaft 35, the squeezing wheel 31 and the two control half layers 41 squeeze the yarn, and the yarn end does not need to be penetrated, which is convenient for operation. It can be operated regardless of whether the yarn is broken, which is convenient for control;
[0035] Secondly, by rotating the fastening bolt 46, the fastening bolt 46 squeezes the control spring 45, and the control spring 45 applies pressure to the squeezing plate 44, so that the squeezing effect between the squeezing plate 44 and the outer control half layer 41 is strengthened. Then, the yarn is clamped by the squeezing wheel 31 and the control half layer 41, and the movement of the yarn causes the two to rotate, and the resistance to rotation increases. The yarn becomes taut after movement, and the tautness can be adjusted by the fastening bolt 46.
[0036] The control ring 24 can be clamped into the bayonet 23 at different positions, so that the position of the control ring 24 can be changed, and the position of the operating part 1 3 can also be changed along the circumferential direction of the operating part 2 4, which is suitable for yarns moving in different directions, so that the extrusion wheel 31 and the control half layer 41 can squeeze the yarn.
