Description

Technical Field

[0001] This application relates to the technical field of straight twisting machines, and particularly to a yarn feeding wheel for a straight twisting machine. Background Technology

[0002] In the textile industry, the straight twisting machine, as an important piece of textile machinery, undertakes the key task of twisting yarn to improve its strength, toughness, and other qualities, meeting the production needs of different fabrics. The yarn feeding wheel is an indispensable core component of the straight twisting machine. Its main function is to perform twisting operations on the yarn, whether it is a single yarn or multiple yarns, the yarn feeding wheel can play its twisting role.

[0003] In the structural design of yarn feeding wheels, a yarn threading hole is set at its center. The yarn is threaded through this hole and then enters the twisting process. However, the yarn feeding methods of existing yarn feeding wheels on the market have significant limitations.

[0004] Common yarn feeding wheels have a relatively simple yarn feeding method; they can only feed yarn from top to bottom or from bottom to top, and the yarn eventually comes out from the side of the rotating disc on the yarn feeding wheel.

[0005] This single yarn-threading method limits the actual production capabilities of straight twisting machines. When faced with different types and specifications of yarn and diverse twisting process requirements, the fixed yarn-threading direction and exit position cannot be flexibly adjusted, making it difficult to meet complex and ever-changing production needs. Utility Model Content

[0006] To solve the above-mentioned technical problems, this application provides a yarn feeding wheel for a straight twisting machine.

[0007] This application provides a yarn-gathering wheel for a straight twisting machine, which adopts the following technical solution: A yarn gathering wheel for a straight twisting machine includes a yarn gathering wheel body, a rotating disk on the yarn gathering wheel body, a threading hole on the axis of the yarn gathering wheel body, and a yarn outlet hole on the side wall of the rotating disk, the yarn outlet hole communicating with the threading hole. The rotating disk is equipped with a thread guide, which is located inside the thread hole and extends toward the outlet hole. The thread guide has two guide surfaces for guiding the yarn to the outlet hole, and the two guide surfaces face the two ends of the thread hole respectively.

[0008] In one embodiment: the side wall of the rotating disk is provided with a mounting hole communicating with the wire hole, the mounting hole and the wire outlet hole are respectively provided on both sides of the wire hole, and the wire guide is installed in the mounting hole.

[0009] In one embodiment: the lead wire is axially slidably and axially fixedly mounted in the mounting hole, and the mounting hole is provided with an adjusting member for adjusting the position of the lead wire.

[0010] In one embodiment: the adjusting member is threadedly connected to the mounting hole, and the adjusting member is rotatably connected to the lead wire.

[0011] In one embodiment: the straight twisting machine yarn feeding wheel includes a pulley for driving the yarn feeding wheel body to rotate, a mounting bracket for rotating the pulley, and a brake assembly for locking the yarn feeding wheel body, the pulley being mounted on the bottom of the yarn feeding wheel body.

[0012] In one embodiment, the brake assembly includes a rotatable swing member rotatably mounted on a mounting bracket, a brake block mounted on the swing member, an elastic member for providing a force to the swing member away from the direction of the wire feed wheel body, and a control member for controlling the swing member to swing towards the direction of the wire feed wheel body.

[0013] In one embodiment, the actuator is a pneumatic cylinder or a hydraulic cylinder.

[0014] In one embodiment: the operating member includes an eccentric block rotatably mounted on the mounting frame and a hand lever connected to the eccentric block. The eccentric block is provided with a positioning plane, and the swing member is provided with a stop plate for abutting against the positioning plane. When the positioning plane abuts against the stop plate, the brake block abuts against the main body of the wire wheel.

[0015] In one embodiment: a mounting plate is adjustablely mounted on the swing member, and the brake block is fixedly mounted on the mounting plate.

[0016] In summary, this application has the following beneficial effects: 1. The yarn is guided by the yarn guide, so that the yarn can pass through the exit hole whether it is passed from top to bottom or bottom to top; 2. With the adjustable thread guide setting, the yarn that is threaded through the thread hole at the top or bottom can be either brought out through the exit hole or directly out from the other end of the thread hole. 3. The brake assembly allows for the stopping of a single wire-gear body without stopping the entire machine. Attached Figure Description
