Chenille defect-free shutdown operation auxiliary device and using method thereof

Abstract

The invention discloses a chenille defect-free shutdown operation auxiliary device and a using method thereof. The chenille defect-free shutdown operation auxiliary device comprises a rotary disc for winding yarn on a distance cutting piece, a rotating shaft is arranged on the upper part of the rotary disc, a rotary motor is connected to the upper part of the rotating shaft, the rotary motor is installed on a supporting plate, a swing arm is arranged on the lower part of the rotary disc, an output roller is arranged on the lower part of the swing arm, the distance cutting piece is arranged in the middle of the output roller, a blade is arranged on the lower part of the distance cutting piece and arranged on a knife rest, and a pair of guide wheels is arranged on the lower part of the output roller and arranged on a guide wheel support. After yarn is clamped by a yarn clamping device, downward force is generated on a sliding block due to the inertia effect, the sliding block moves downwards along the inner wall of the sleeve to compress a first spring, inertia buffering of the yarn can be achieved through the first spring, and secondary breakage of the yarn can be avoided; and in addition, tension can be adjusted when the yarn is knotted, after broken ends are connected, the yarn has the same tension as the original tension, and synchronous conveying of the yarn is guaranteed.

Description

technical field [0001] The invention relates to the technical field of textile equipment, in particular to a chenille non-defective shutdown operation auxiliary device and a use method thereof. Background technique [0002] Chenille often needs to be shut down for processing due to yarn breakage during the production process. Although each stop will cause waste of raw materials due to knotting, if the raw materials are used up, the machine must be shut down to replace the raw materials. There is bound to be an end. The patent document with application number 201810500384.1 discloses a chenille defect-free shutdown operation auxiliary device, which realizes the defect-free operation of chenille products during shutdown. Through the principle of electromagnetic adsorption, a thread lifter is installed on one side of the output roller, and the electromagnet cooperates with the yarn break detector. The action of the threader lifts the yarn. However, in actual production activ...

Problems solved by technology

However, in actual production activities, the yarn has a certain tension in the process of forward feeding and transportation. After the yarn breaks suddenly, the yarn will untwist due to the existence of inertia. Jamming is very likely to cause secondary breakage of the yarn, but no effective measures have been taken in the prior art, and in this patent document only the rotation of the rotary rod is used to realize the yarn after the yarn is jammed. In addition, in this patent document, the electromagnet is directly used to drive the rotating rod to rotate to lift the yarn, but it cannot completely control the distance of the yarn lift, so it is impossible to adjust the tension of the yarn In view of the above-mentioned many disadvantages in the chenille non-defective shutdown operation auxiliary device in the prior art, the present invention proposes a new chenille non-defective shutdown operation auxiliary device and its use method
