A warping machine for preventing warp damage

Abstract

The invention relates to the field of textile technology. The purpose is to provide a warping machine capable of balancing unwinding tension and preventing warp yarn damage, including a creel, the creel includes a frame body and several unwinding units arranged on the frame body; the unwinding unit includes a mounting frame, and the mounting frame includes A horizontal bottom plate and two vertical side plates, the bottom plate is a right triangle, and the side plates are fixed on the two right-angled sides of the bottom plate; two free-rotating bobbin mounting seats are symmetrically arranged on the two side plates, and the bobbin Yarn bobbins are sheathed on the installation seat, and the yarn bobbins are distributed in an inverted V shape; the area between the two yarn bobbins on the mounting plate is provided with a damping type tension drop buffer. The invention can replace the bobbins without stopping the machine, and at the same time, it can reduce the situation that the tension drops too much due to the influence of the length of the splicing section when one bobbin is unwound and switched to another bobbin for unwinding, effectively The adjustment and control of the tension is realized, and the warp and equipment damage are prevented.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a warping machine for preventing warp damage. Background technique [0002] The warping machine is a device that winds a certain number of warp yarns on the warp beam according to a certain width and evenly spaced according to the process design requirements. It mainly includes a creel, a yarn collecting board and the main body of the warping machine. Guided by the mechanism, it is evenly wound on various parts of the warp beam in turn. In the long-term practice process, the existing warping machines mainly have the following problems: [0003] 1. The traditional warping creel includes a single creel and a double creel. A yarn bobbin can be set in each unwinding unit of a single creel. When the unwinding speed and conveying speed of the bobbin are good, since the warp yarns on multiple bobbins can basically be unwound synchronously, it is also possible to unwind in batches. O...

Problems solved by technology

However, this method also has certain defects. Since the warp yarns on different bobbins have a certain length at the joint, after the last unwinding of the previous bobbin is completed, the tension will suddenly decrease, which will easily cause the equipment to misjudge as A disconnection occurs and a shutdown occurs

At the same time, the sudden and large change of the tension will easily cause the yarn to be entangled, which will cause damage to both the yarn and the equipment.

In addition, because the range of tension reduction is too large, even if the warping machine is equipped with a device for real-time tension detection and online correction, it is often impossible to quickly correct tension imbalance

[0005] 2. During the process from unwinding to winding, the warp yarn passes through the wires of several guide parts, such as: guide wheels, guide rods, guide holes, etc. In the process of warp yarn contacting these guide parts, there will inevitably be some frictional force, which in turn leads to the accumulation of static electricity on the surface of the warp yarn. The accumulation of static electricity will not only affect the quality of the warp yarn itself, but also cause certain safety hazards

However, for some pieces of cloth, due to the large width, the number of warp threads required is also large, and due to the limited capacity of a single creel, users often need to use multiple creels for warp unwinding

This results in a relatively scattered distribution of creels in the width direction, which in turn causes warp yarns to have a large bending angle when passing through the yarn collecting plate. If the bending angle is too large, it will not only wear the warp yarns, but also increase the number of broken threads. risks of
