Double-roller non-crease winding mechanism of silk velvet gripper loom

Abstract

A double-roll no-crease reeling mechanism on velour rapier looms: A leading roll shaft is supported on a reeling shaft through two connection arms; the connection arms are arranged with notches; one end of a Chinese character ''Qi'' shaped angle regulator bar is fixed to connect with a frame; the other end is put through the notch on the connection arm; the leading roll can be rotated on the external surface along the reeling roll in a certain range; the reeling shaft can drive the leading roll shaft and the leading roll to rotate through a gear set; the leading roll is arranged to the right of the reeling roll; a center-connecting line of the leading roll and the reeling roll is in an included angle of 0 degree to 50 degrees against the horizontal level. Due to optimization of the leading roll in the double-roll reeling mechanism, the double-layer flannelette can be output along a straight line to reel on a cloth beam; because of an identical line speed in reeling process, the connection arm can be used to adjust contact between the reeling roll, the leading roll and the double-layer flannelette. Thus, the invention can effectively prevent cloth dropping off because of tension factors, guarantee reeling reliability and stability, and prevent crease from occurence.

Description

Technical field: [0001] The invention relates to a velvet loom, in particular to a velvet rapier loom improved on the basis of a flexible rapier loom. Background technique: [0002] The original velvet looms are all shuttle looms. The typical models are SGD652 (cut velvet on the machine) and SGD653 (cut velvet under the machine). These two models have complex structures and high failure rates during use. The qualification rate is low and the maintenance cost is high. With the innovation of velvet technology, this type of machine can no longer adapt to the technological requirements of modern velvet weaving. Germany and Japan have produced a velvet loom, which can well meet the current velvet weaving technology requirements, but the price is very expensive. , the single price is 300,000 yuan to 500,000 yuan / set, which requires high technical requirements for operators, which is unacceptable to domestic velvet production enterprises. The flexible rapier loom is a kind of shu...

[0002] The original velvet looms are all shuttle looms. The typical models are SGD652 (cut velvet on the machine) and SGD653 (cut velvet under the machine). These two models have complex structures and high failure rates during use. The qualification rate is low and the maintenance cost is high

With the innovation of velvet technology, this type of machine can no longer adapt to the technological requirements of modern velvet weaving. Germany and Japan have produced a velvet loom, which can well meet the current velvet weaving technology requirements, but the price is very expensive. , the price of a single unit is 300,000 to 500,000 yuan per unit, which requires high technical requirements for operators, and domestic velvet manufacturers cannot accept it.

The flexible rapier loom is a kind of shuttleless loom with a large amount of social ownership and very mature technology, but it cannot weave flannel, let alone velvet. If it is improved on the basis of the flexible rapier loom, It is people's expectation that it can be used for velvet weaving, and it is the optimal plan for the economical transformation of velvet looms in my country. Our company has carried out long-term research and exploration for it. The flexible rapier loom can meet the requirements of the velvet weaving process. It is necessary to improve the double-roller winding mechanism of the existing flexible rapier loom to ensure that the double-layer velvet does not produce creases during the winding process, so as not to affect the quality of the cut pile and dyeing. effect, reducing the quality of flannelette
