Description

Technical Field

[0001] The utility model relates to the technical field of nylon zipper processing, in particular to a nylon yarn drawing machine for nylon zippers. Background Art

[0002] The main function of the drawing machine is to apply external force in the axial direction of the tow under certain conditions to thin the single fibers (or nylon fibers) in the tow, increase the degree of orientation, and change the single fibers from a plastic state of low strength and high elongation to an elastic state of high strength and low elongation.

[0003] For example, Chinese patent CN213866524U discloses a drawing machine, including a panel, a traction roller and a self-locking wire roller, the self-locking wire roller is hollow, a rubber ring is wound on the self-locking wire roller, and the rubber ring includes a wrapping portion, a first embedded portion and a second embedded portion, the wrapping portion is wrapped around and abuts against the outer side wall of the self-locking wire roller, the first embedded portion is integrally arranged at one end of the wrapping portion, and the second embedded portion is integrally arranged at the other end of the wrapping portion, an embedding hole is opened on the self-locking wire roller, the first embedded portion and the second embedded portion are both embedded in the embedding hole and extend into the self-locking wire roller, and the first embedded portion abuts against the second embedded portion. This application has the effect that when the rubber ring is damaged, there is no need to remove the cylinder and then remove the entire rubber ring from one end of the roller. The rubber ring can be taken out from the outer side wall of the roller by only pulling the first embedded portion and the second embedded portion out of the embedding hole. The structure is simple and the operation is convenient.

[0004] However, the above scheme still has certain problems during use. The conveying roller on the drawing machine is directly exposed to the outside. When the drawing machine is running, the conveying roller will rotate at high speed. When the staff accidentally touches the high-speed rotating conveying roller, the staff is easily drawn into the drawing machine, causing casualties. Therefore, a nylon yarn drawing machine for nylon zippers is proposed to solve the above problems. Utility Model Content
