Covered yarn machine connection head knotting device

Abstract

The invention discloses a covered yarn machine connection head knotting device. The covered yarn machine connection head knotting device comprises a base and a knotting device; the knotting device isarranged on the base and comprises a screw rod, a three-claw knotting head, a control device and a knotting bracket connected with the base, wherein the control device controls the screw rod to reset;the screw rod is connected with the knotting bracket, the three-claw knotting head is connected to the end of the screw rod, and the knotting device also comprises a wire cutter; the wire cutter is parallel and opposite to the three-claw knotting head and is connected with the base and composed of a wire guiding rack, a blade and a spring resetting device; one end of the wire guiding rack is fixedly connected to the base, the other end of the wire guiding rack is an annular bracket with a notch, the blade is rotatably connected to the wire guiding rack and comprises a cutting part and a control part, the control part is connected to the spring resetting device, and the spring resetting device is fixed to the base. By adding the wire cutter on the knotting device, useless yarn tails afterknotting are cut off, and the influence caused by the excessively long yarn tails on the quality of covered yarn is reduced.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to the field of spinning, in particular to a knotting device for covered silk machine joints. Background technique [0002] Covered yarn machine is used to spirally wind silk, polyester and other chemical fiber filaments and cotton fibers on spandex core wire. The coated yarn that can be produced has both the elasticity of spandex and the appearance and good It provides an ideal covered silk raw material for the production of elastic fabrics and knitted fabrics. [0003] During the operation of the covering machine, when the yarn is used up, it is necessary to change the yarn joint. In the production, the manual joint is generally used. The manual joint is small and has little impact on the subsequent process, but the manual speed is difficult to keep up with the entry of the yarn. speed, which makes it unable to achieve satisfactory results under high-speed operation. When the pu...
