A self-braking winder for canvas processing based on the principle of quantitative winding

Abstract

The invention relates to the technical field of canvas processing, and discloses a winding machine for canvas processing causing self-braking based on quantitative winding principle. The winding machine comprises a base, and a unidirectional rod is movably connected in the base; a ratchet wheel rotates and drives a drum to rotate and wind to achieve the winding effect, a doubling thread pushes a top block to move upwards, drives a clamping block to move downwards to engage with the ratchet wheel, the movement of the ratchet wheel is blocked, when the doubling thread on the drum reaches the required specifications, the ratchet wheel is stopped, so the produced drums with inconsistent sizes are avoided, the produced bobbins with inconsistent sizes are not conducive to subsequent storage anduse, the top block moves upwards and drives a stop rod to be away from a rotating rod, the bobbins are convenient to take out, and the unidirectional rod prevents the stop rod from closing the rotating rod under the condition of no drum, so the condition that the ratchet wheel rotates again when new drums are not sleeved outside the rotating rod is avoided, the ratchet wheel is always in a stationary state when the stop rod and the rotating rod are in a separating state, and when the stop rod is in contact with the rotating rod again, the ratchet wheel rotates again.

Description

technical field [0001] The invention relates to the technical field of canvas processing, in particular to a winder for canvas processing that causes self-braking based on the principle of quantitative winding. Background technique [0002] Canvas is a thicker textile made of cotton or hemp. Canvas is divided into coarse canvas and fine canvas. Canvas has a wide range of uses. Coarse canvas is tough and has good waterproof performance. It is often used to make field tents, The material of the roof of the open-air warehouse, fine canvas is soft, and the most common fine canvas products are backpacks and shoes. The canvas is made of two or more strands of thread after twisting and then weaving through four processes of warping, weaving and dipping. At present, the canvas has the following problems in the process of twisting: [0003] Although the existing automatic winding machine has a high degree of automation, it has a complex structure, a large footprint, and high cost, a...

Problems solved by technology

[0003] Although the existing automatic winding machine has a high degree of automation, it has a complex structure, a large footprint, and high cost, and is not suitable for small factories. According to the winding situation, the equipment is turned off to replace the new reel by itself, the operation is cumbersome and the efficiency is low, and there is a large error in the size of the reel, and there are irregularities in storage, which cannot make full use of the space
