A woven bag circular spinning machine equipped with a stop device for thread breaking and missing thread

Abstract

The invention relates to a woven bag circular textile machinery with a breaking line and lacking of line stop device. The circular textile machinery main body comprises a control device, a control host and a signal projector, wherein the control device controls the operation of the circular textile machinery. A weft coil is fixed on a ring rotation mechanism of a rack via a fixed element. A tray is disposed under the weft coil, and the tray is hinged on the ring rotation mechanism. A spring block is connected to the lower surface of the tray and is fixed on the ring rotation mechanism. A switch is installed inside the spring block. When the spring block bounces, the switch is on. When the spring block retracts, the switch is off. The switch, the signal projector and a power supply are on circuit I. When the switch is on, the signal projector starts to issue stop signal to the control host. The invention has the advantages that the breaking line and lacking of line stop device is applied by the invention, if the breaking of warp is found late, the woven area will become a defective product, the material is wasted and the efficiency is reduced. If the weft is ran out of, the step of artificial threading is reduced, and a large number of labor and time is saved.

Description

technical field [0001] The invention relates to production equipment for woven bags, in particular to a woven bag circular spinning machine equipped with a stop device for thread breakage and missing thread. Background technique [0002] The current woven bag production is through a woven bag circular spinning machine. Generally speaking, multiple warp threads form a column and move from top to bottom, while the weft thread forms a circular spiral that alternately passes through the multiple warp threads to weave the warp thread and weft thread. It is a columnar braid, and then cut the braid in the middle according to the size of the woven bag, and sew the cuts at one end together with a seaming machine, and the woven bag is formed. [0003] In actual production, there are two problems. One is that the warp thread is easy to break, because there are many warp threads, and the process of moving from top to bottom is relatively far, so it is easier to break the thread. After ...

AI Technical Summary

Problems solved by technology

Another problem is that the weft thread on the weft thread coil is easy to run out, and the weft thread coil is fixed on the ring-shaped rotating mechanism to rotate with the weft thread, because in the weaving process, every time the warp thread moves down by the width of a weft thread, the weft thread will move the entire ring. One week of knitting, so the weft thread consumption is very large. Once the weft thread is used up, not to mention defective products, it is necessary to use new weft thread to manually intersperse with all the warp threads in one circle. If you pay attention, the warp thread will be broken. It is very troublesome. Even a skilled worker will take 30 minutes

Weft threads are used up quickly, so a lot of labor is wasted

Therefore, the maintenance of three such machines requires 7-9 people to operate normally.
