Safety device for filling strainer

Abstract

The present invention relates to a safety device for a weft yarn straightening machine, in particular to a safety device installed at a suitable position of the weft yarn straightening machine, and the safety device includes: guide rods, which are fixedly installed on the weft yarns The upper and lower parts of the inner wall of the opposite right frame and left frame of the straightening machine body; the slider, which is connected with the guide rod, is used to support the stretching roller; the strong compression spring and the weak compression spring, the strong compression spring and the weak compression Springs are mounted on the front and rear of the guide rods to control the rearward movement of the slider while preventing impact; cutters, which are installed between the guide rods; cutting guide rods, to cut the fabric easily and guide rollers installed at the lower and upper portions of the safety device for guiding the fabric. When a considerable load is applied to the fabric, the cutter automatically cuts the fabric to prevent deformation and damage of peripheral mechanisms including the weft straightening machine.

Description

technical field [0001] The present invention relates to a safety device for a weft straightening machine, and more particularly to a safety device installed at a suitable location of the weft straightening machine, such as at the top, bottom or Center for preventing premature deformation or damage of various mechanisms by automatically cutting the fabric when a large load is applied, such as peripheral units or tenters including weft straightening machines or components, in order to extend the The service life of various fabric finishing machines, thereby preventing fabric damage and degradation; wherein this large load is caused by electrical errors during the transfer of fabrics, wrong operation of lines or machines, or carelessness of workers. When the fabric is reversely wound on the various rollers of the tenter frame, such as the press rollers on the same line as the weft straightening machine, the resulting large reverse load is also applied to the fabric that has passe...

AI Technical Summary

Problems solved by technology

Therefore, when a very strong tensile force is applied to the fabric, at the same time, each roller and the bearings, parts, etc. supporting the roller are easily deformed and damaged

In extreme cases, the weft straightening machine will be damaged and deformed, requiring additional repair costs

Also, the precision of the machine will be significantly reduced and a large amount of fabric will be lost

[0005] Damage to the above equipment and loss of fabrics are due to various reasons such as carelessness of the staff and wrong operation of machines or lines and electrical errors etc.

When the above damages occur one or more times, the accuracy of the machine is significantly reduced due to the impact, this reduced accuracy leads to a reduction in the quality of the fabric, in addition to loss of fabric and additional repair costs
