Braiding machine disconnection protection device

Abstract

The invention discloses a broken line protection device of knitting machine. The broken line protection device comprises a base, wherein a supporting column is arranged on the base; a winding drum isarranged at the top of the supporting column; a coaxial ratchet wheel is arranged on the side surface of the winding drum; a bent rod is hinged to the middle part of the supporting column; a pawl is arranged at one end of the bent rod; the pawl is matched with ratchets on the ratchet wheel; the other end of the bent rod is connected with a balance weight block through a spring; the balance weightblock is arranged on the supporting column in a sliding connection manner; a left fixed pulley and a right fixed pulley which are horizontally arranged are respectively arranged on two sides of the balance weight block; an L-shaped bracket is arranged on the supporting column; a lead wire hole is formed in the L-shaped bracket; a yarn on the winding drum passes through the left fixed pulley, the right fixed pulley and the lead wire hole in sequence; the side part of the balance weight block is provided with a connecting rod; the connecting rod is connected with an induction unit. The broken line protection device is high in stop sensitivity, can further realize stop protection for the winding drum to avoid the waste of the yarn and the disorder of the yarn and is relatively good in use effect.

Description

technical field [0001] The invention relates to equipment in the field of textiles, in particular to a wire breakage protection device for a knitting machine. Background technique [0002] The knitting machines used in the textile industry need to be weaved with yarn. The yarn is fed from the reel to the weaving machine for weaving. Since the yarn is easy to break, a yarn breakage sensor will be installed between the reel and the weaving machine. , so that the broken yarn can be found in time for maintenance. The conventional yarn broken sensing device generally detects and senses through infrared, and alarms and stops after the broken thread. However, such a sensing device has the following problems: not only the parking sensitivity is low, but also the reel cannot Downtime will cause yarn waste and yarn confusion, and the use effect is not ideal. Contents of the invention [0003] The purpose of the present invention is to provide a braiding machine thread break protect...
