Abstract
Description
Technical Field
[0001] This utility model relates to the field of water jet loom technology, specifically a tensioning device for a water jet loom. Background Technology
[0002] A water jet loom is a shuttleless loom that uses a jet of water to guide the weft yarn through the shed. It uses water as the weft guiding medium and utilizes the force of the water jet to propel the weft yarn from the loom to the warp and weft.
[0003] During the yarn feeding process of a water jet loom, the yarn is fed through multiple traction rollers. When different types of yarn need to be transported and woven, the resistance generated between different types of yarn and the traction rollers is different, so different types of yarn may wrinkle or loosen on the traction rollers.
[0004] Therefore, a tensioning device for water jet looms is needed to improve the above-mentioned problems. Utility Model Content
[0005] The purpose of this invention is to provide a tensioning device for a water jet loom to solve the problems mentioned in the background art.

[0007] A tensioning device for a water jet loom includes a water jet loom body. Guide plates are arranged on the left and right sides of the front of the water jet loom body. A through groove is opened in the middle of the side wall of the guide plate. Tensioning rollers are symmetrically arranged on the inner side of the guide plate. External shafts are arranged at the left and right ends of the tensioning rollers. Rotating plates are arranged at the outer ends of the external shafts. Rotating seats are connected between the rotating plates. A cylinder is installed on the rear side of the rotating seats. Yarn is wound between the tensioning rollers.
[0008] As a preferred embodiment of this utility model, the external shaft passes through the through groove, and the connection between the external shaft and the through groove is a sliding connection.
[0009] As a preferred embodiment of this utility model, the connection between the external shaft and the rotating plate is a rotatable connection.
[0010] As a preferred embodiment of this utility model, the connection between the rotating plate and the rotating base is a rotatable connection.
[0011] As a preferred embodiment of this utility model, the external structure of the rotating base is designed in the shape of an "I".
[0012] As a preferred embodiment of this utility model, the cylinders are respectively installed on the left and right sides of the water jet loom body.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. In this utility model, the guide plate, through groove, external shaft, rotating plate, rotating seat and cylinder can drive the two tensioning rollers to move towards each other and outwards through linkage, so as to facilitate the tensioning operation of the yarn wound on the tensioning rollers.
