The yarn dividing device can realize simultaneous yarn dividing of a plurality of strands of knitting raw material yarns in the whole roll of cloth in a small space, yarn dividing efficiency is high, and the length of each strand of knitting raw material yarn can be cut out at will.
Meanwhile, the invention also provides a yarn dividing machine for forming the knitting raw material yarn. It makes the cloth of cutting the yarn end of a thread can automize and move back the book → divide the silk → convolute, consequently, adopt behind this branch silk machine, it not only can reduce operating personnel's working strength by a wide margin, and the output of one day can reach 1000KG moreover.
In order to solve the technical problems, the invention adopts the following technical scheme:
a yarn separator for forming knitting raw material yarn is capable of synchronously separating yarn from a cloth material formed with a plurality of strands of knitting raw material yarn ends, and comprises a first yarn dividing roller and a second yarn dividing roller which extend along the width direction of the cloth, and a driving mechanism which respectively drives the first yarn dividing roller and the second yarn dividing roller to rotate around the axis direction of the driving mechanism, wherein, the thread ends of the plurality of strands of knitting raw material yarns are distributed along the width direction of the cloth in a staggered way towards the front side and the back side of the cloth in sequence, the thread ends of the plurality of strands of knitting raw material yarns close to the front side of the cloth form a first yarn group, the thread ends of the plurality of strands of knitting raw material yarns close to the back side of the cloth form a second yarn group, the first yarn group is wound on the first yarn dividing roller, the second yarn group is wound on the second yarn dividing roller, when dividing silk, the first silk dividing roller and the second silk dividing roller rotate oppositely to tear the first yarn group and the second yarn group from the joint of the yarn ends of two adjacent knitting raw material yarns respectively.
Preferably, the cloth is wound on the first yarn dividing roller, and the second yarn dividing roller gradually tears off the second yarn group attached to the first yarn dividing roller from the first yarn group. Therefore, the position of the tearing point is positioned on the first yarn dividing roller instead of between the first yarn dividing roller and the second yarn dividing roller, so that cloth entering the yarn dividing device is relatively stable and cannot shake, the first yarn group and the second yarn group can be torn off conveniently, and the probability of yarn breakage is greatly reduced.
According to a specific implementation and a preferable aspect of the invention, the first yarn dividing roller and the second yarn dividing roller are identical in structure and uniformly comprise a roller body and a sleeve body which can be replaced and arranged on the outer periphery of the roller body, wherein the outer periphery of the sleeve body is a rough surface. The contact friction force between the cloth and the yarn dividing roller is increased through the arrangement of the sleeve body, and the first yarn group and the second yarn group can be further torn off.
