Tension-controllable weft storage unit

Abstract

The invention discloses a tension-controllable weft storage unit which comprises a shell, a tension control mechanism and a fixing device, wherein the tension control mechanism and the fixing device are arranged in the shell; the tension control mechanism is arranged in the fixing device, and comprises a yarn nose seat, a tension spring device and a sleeve; the tension spring device and the sleeve are arranged in the yarn nose seat; the tension spring device comprises a tension spring, a push plate and a fixing seat; the push plate is fixed at the left side of the tension spring; the fixing seat is fixed at the right side of the tension spring; the fixing device comprises a fixing disk, a positioning tray and a pressing crank; a fixing base plate is arranged in the shell; a moving rail is arranged on the fixing base plate; a heat dissipation groove is formed in the right side of the shell. The tension-controllable weft storage unit is high in practicability, so that the stability of the weft storage unit during working is improved; meanwhile, the tension control effect is guaranteed, the whole process is convenient to operate, the effect is obvious, and the working efficiency is improved.

Description

Technical field [0001] The invention relates to a weft feeder with controllable tension. Background technique [0002] Compared with shuttle looms, modern shuttleless looms have greatly improved the weft insertion speed. At the same time, the quality of the fabric is also more advanced. Therefore, the weft insertion tension is required to be very uniform during the weft insertion process to avoid weft insertion The tension fluctuates violently, so that the tension of each weft thread introduced into the shed remains consistent. The setting of the weft feeder can avoid large tension fluctuations when the weft yarn is pushed directly from the bobbin, so as to achieve the purpose of reducing the weft insertion ends and improving the quality of the fabric. [0003] When in use, pre-store a certain number of yarns on the weft feeder, drive them through a belt, and then supply them to the loom to ensure that all yarns have a uniform tension. It can be applied to cotton, wool, hemp, sil...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a weft feeder with controllable tension. It mainly aims at the problems existing in the work of the weft feeder in the prior art, and provides a weft feeder with simple structure, convenient operation and good working effect. The setting of the weft feeder can facilitate the user to control the tension of the weft feeder, and enhance the maneuverability. Through the setting of the fixing device, the tension of the weft feeder can be controlled evenly during the working process. Adjust the size of the tension, the whole process is easy to operate, the effect is obvious and the work efficiency is improved
