Description

Technical Field

[0001] This utility model relates to the technical field of core-spun yarn equipment, specifically to a multifunctional high-speed guide roller core-spun yarn device. Background Technology

[0002] The core-spun yarn device is the mechanism on a ring spinning machine that spins core-spun yarn. Core-spun yarn is divided into non-elastic core-spun yarn and elastic core-spun yarn. Spinning these two types of core-spun yarn requires their own specialized devices. Moreover, the spinning speed of the core-spun yarn device on existing equipment is relatively low, and the connection between the guide rollers often fails during operation, leading to problems such as the guide rollers stopping rotating, core-spun yarn breakage, wrinkles, and defective fabric. At the same time, the guide rollers wear and deform, making repair and disassembly very difficult, causing downtime and affecting production. Utility Model Content

[0014] 2. This utility model connects the guide rollers through a cross slider and a connector, which solves the problem of wear and breakage caused by the difference in coaxiality between guide rollers while smoothly transmitting torque. At the same time, it also increases the rotational speed of the guide rollers, raising the limit speed of the guide rollers from 100 rpm to 220 rpm, thereby effectively improving the spinning speed of core-spun yarn. Furthermore, when replacing the guide rollers, they can be removed individually without affecting other guide rollers, saving time and effort and improving the efficiency of equipment maintenance.
