Description

Technical Field

[0001] This utility model relates to the field of twisting machines, and in particular to a braking mechanism and a twisting machine thereof. Background Technology

[0002] A twisting machine is a piece of equipment used in the textile industry, mainly for twisting yarn. During the operation of the twisting machine, the braking mechanism is an important component. Its main function is to control the tension of the yarn and ensure the stability and quality of the yarn during the twisting process.

[0003] Braking mechanisms are generally classified into mechanical brakes, pneumatic brakes, electromagnetic brakes, and hydraulic brakes. They all brake the shaft of the twisting machine. The braking mechanism is installed on the shaft of the twisting machine. In the working environment of the twisting machine, cotton fibers will float. When the cotton fibers enter the braking mechanism, the friction of the braking mechanism will cause the cotton fibers to heat up and spontaneously combust, which will lead to spontaneous combustion and damage to the equipment, thus posing a certain safety hazard.

The end cap 5 is mounted on the top of the protective shell 3. The top of the end cap 5 has a shaft hole that matches the shaft of the twisting machine. When the end cap 5 is connected to the shaft, a sealing bushing is installed between them to prevent cotton fibers from entering between the brake disc assembly 1 and the hydraulic caliper housing 2 from between the end cap 5 and the shaft. The filter assembly 6 is installed between the protective shell 3 and the end cap 5. The filter assembly 6 can filter the air flowing inside and outside the protective shell 3 to prevent cotton fibers from entering.

The first dustproof net 62 is fixedly installed inside the mounting frame 61. The aperture of the first dustproof net 62 is 0.5mm-1mm, and the gap between the mounting frame 61 and the protective housing 3 and the end cap 5 is smaller than the aperture of the first dustproof net 62. The slider 64... 3 is fixedly connected to the side of the mounting frame 61. A sliding groove is provided at the top of the inner wall of the mounting groove. The outer wall of the slider 63 is slidably sleeved with the inner cavity of the sliding groove. The end of the positioning rod 64 is fixedly connected to the end cover 5 and the protective shell 3 respectively. Positioning grooves are provided at the top and bottom of the mounting frame 61.
