Description

Elastic thread conveying device

Technical Field

The utility model relates to a conveyor, especially elastic wire conveyor.

Background

Currently, many fabrics with elastic properties (such as socks) are woven using elastic threads; the common elastic thread conveying device guides the thread by arranging a plurality of thread guide pipes, and pulls out the elastic thread on a winding drum by the pulling force generated when the elastic thread is used during weaving; because the elastic threads are rolled into a roll for storage, the elastic threads on the outer layer can gradually extrude the elastic threads on the inner layer, so that the elastic threads on the inner layer are compacted and clamped; when the elastic wire on the winding drum is directly used for traction, the elastic wire is easy to block, and the blocking condition is difficult to reflect to workers; the elastic thread is continuously woven after the elastic thread is clamped, the thread breakage can occur (the process from clamping to thread breakage is short, and the thread breakage is difficult to prevent even if a worker can find the thread breakage in time); before the machine is not stopped and the elastic threads are reconnected, the elastic fabrics woven subsequently are all defective products, so that the production cost is greatly increased, and great troubles are caused to enterprises; and the subsequent re-wiring operation affects the hosiery-knitting efficiency of the hosiery-knitting machine.

In addition, the loom can only ensure that the lengths of the elastic threads woven into the loom are the same every time, so that the elasticity of the elastic fabric is ensured to be uniform, but the elastic threads have certain elasticity, and due to manufacturing errors, the elasticity of each part of the whole elastic thread can be different, so that the elastic fabric of a finished product still has certain elasticity difference.

Therefore, the existing elastic thread conveying device has the problems that thread jamming is not timely found, thread breakage is easily caused, the conveying efficiency is low, and elastic errors exist in the elastic threads during conveying.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an elastic thread conveyor. The utility model discloses not only can in time discover the card line, still have the advantage of the elasticity error of difficult broken string, conveying efficiency is higher and can eliminate the elasticity line.

The technical scheme of the utility model: the elastic wire conveying device comprises a vertically arranged mounting plate, and a vertically arranged polished rod is fixed on one side of the mounting plate; the polished rod is connected with a sliding block in a sliding way, and the sliding block is connected with a guide wheel in a rotating way; the sensor is fixed at the position of the mounting plate corresponding to the middle of the polished rod, and the positions of the mounting plate corresponding to the two sides of the top of the polished rod are respectively provided with a wire inlet wheel and a wire outlet wheel.

In the elastic thread conveying device, the mounting plate is fixed with the limiting column parallel to the polish rod, and the sliding block is provided with the sliding chute in sliding clamping connection with the limiting column.

Compared with the prior art, the utility model improves the prior elastic thread conveying device, and the elastic thread forms a U shape by passing through the thread inlet wheel, the guide wheel and the thread outlet wheel in sequence; when the elastic thread is clamped, the guide wheel drives the sliding block to ascend along the polished rod along with the continuous weaving of the elastic thread, when the sensor on the mounting plate senses the sliding block, a signal is transmitted to the controller, and the controller controls the hosiery machine to stop and informs a worker to carry out troubleshooting on the thread clamping condition; even if the equipment has faster response, a certain time delay still exists in the signal transmission process, at the moment, the sliding block can continuously rise along the polished rod to play a role in buffering the time delay response, and the elastic wire is prevented from being tensioned and broken; the system can be restarted quickly after the fault of the wire clamping is eliminated, the maintenance interval is short, the wire connection is not needed again, and the conveying efficiency is high; when the elastic wire is conveyed, the sliding block is arranged on the polished rod in a sliding mode, the guide wheel can be supported by the elastic wire, and the elastic wire can be stretched by the weight of the sliding block and the weight of the guide wheel; when the elasticity of the elastic thread is increased, the sliding block moves downwards along the polished rod to stretch the elastic thread, when the elasticity of the elastic thread is decreased, the elastic thread is shortened to enable the sliding block to ascend along the polished rod (the elastic error of the elastic thread is limited, a sensor cannot be triggered to generate false alarm), and the elastic error on the elastic thread can be eliminated. In addition, the mounting plate of the utility model is fixed with a spacing post parallel to the polished rod, the slide block is clamped in the chute in a sliding way, so that the slide block can only slide along the polished rod, the sliding direction can be limited, the guide wheel can not deviate, and the conveying stability of the elastic wire is ensured to be stronger; the sensor is a Hall sensor, and the Hall sensor can be triggered by the magnet when the sliding block moves upwards excessively, so that an alarm can be given in time; a guide pillar is fixed on one side of the top of the I-shaped guide wheel in the wire inlet wheel, which is far away from the appearing wheel, and the elastic wire can drive the sliding block to move up and down along the polished rod, so that the elastic wire can jump, the guide pillar can limit the elastic wire from jumping out of the wire inlet wheel, and the conveying stability of the elastic wire is ensured; the middle parts of the guide wheel and the wire outlet wheel are provided with ceramic wear-resistant layers, so that the service life of the equipment is longer; and is not easy to generate static electricity to cause fluffing of the elastic thread. Therefore, the utility model discloses not only can in time discover the card line, still have difficult broken string, conveying efficiency is higher, can eliminate the elasticity error of elasticity line, transport stability is stronger, equipment life is longer and the difficult advantage of fluffing of elasticity line.
