Description

Technical Field

[0001] The utility model belongs to the technical field of spinning equipment and relates to a wire guiding hook pull rod device. Background Art

[0002] As a special equipment for producing finished silk, the winding machine plays an important role in the production process of polyester industrial yarn. According to different product specifications, the models of conventional industrial yarn winding machines are 3-head, 4-head, 6-head, and 8-head, these 4 types. In order to meet the basic head-forming winding requirements of the machine, a movable pull rod wire guiding hook device is generally equipped above the 8-head winding machine. Its functions are, on the one hand, to assist operators in hanging the wire and switching during head formation, improving the head-forming switching efficiency; on the other hand, to provide a certain tension during the winding process, play a role in guiding the wire, and stabilize the spinning condition.

[0003] Similar to the limit schemes in a double-lock point steel window handle with positioning function provided by the patent application CN220928995U and a cylindrical pin press-fitting fixture provided by the patent application CN213319812U, the existing limit device for the wire guiding hook pull rod of the winding machine uses the ball head at the front end of the ball head spring set screw to be stuck in the groove on the surface of the pull rod for limiting. However, after the winding machine is used for a long time, the gap between the components of the wire guiding hook pull rod increases, the internal compression spring of the ball head spring set screw deforms, and the pressing force weakens; during the operation of the machine, problems often occur such as the loosening of the wire guiding hook pull rod, resulting in fluctuations in the filament bundle tension, affecting the formation of the silk cake, and even causing broken ends. To solve these problems, the machine needs to be taken off for inspection, adjustment, or even replacing the entire new ball head spring set screw and re-tightening, which greatly reduces the production operation efficiency of the equipment. In addition, during the head-forming switching, problems often occur such as the winding machine switching failure because the operator does not fully push the wire guiding hook pull rod in place, and such mistakes can only be reduced by strengthening personnel operation management and inspection.

[0004] Therefore, it is of great significance to study a new wire guiding hook pull rod device to solve the above problems. Summary of the Utility Model
