Abstract

The invention designs a yarn knotter. The yarn knotter comprises a rope clamping component, a knotting component, a traction component and a transmission component. Yarn ends of the new and old yarn drums are clamped by pneumatic fingers, drawn by a sliding bracket, and clamped by a lower cover and an upper cover to complete the traction and clamping of yarns. Driven by the transmission component,knotting nose pliers and knotting hook pliers complete the winding action of old yarns. Driven by an air cylinder, a rope hook completes the hooking action of new yarns. A fluted disc component tensions the yarns to realize knotting and unhooking actions. The yarn knotter has the advantages of realizing the automation of yarn knotting, solving the problems of slack yarn knotts and excessively long yarn tails, increasing the speed of yarn knotting and improving quality of yarn knotting and the efficiency of yarn tube replacement.

Description

technical field [0001] The invention relates to a yarn knotter used for connecting new and old yarns in the process of carpet weaving, in particular to an automatic yarn knotter used for replacing yarn barrels, and belongs to the technical field of carpet weaving. Background technique [0002] In the carpet weaving process, when the yarn bobbin is used up, the new yarn end must be tied with the old yarn end, so that the two yarns are connected back and forth to continue working. The methods of yarn connection include traditional mechanical knotting, glue bonding, hot-melt connection, and air splicing. Among them, glue bonding needs to match the yarn to select the glue and the knotting speed is slow; hot-melt connection is often used for joints of synthetic fibers and the connection strength is low; there are many auxiliary equipment for air splicing, and the maintenance and repair costs are high. It is suitable for thinner yarns, and the splicing effect on rovings is poor. ...
