Abstract

The invention belongs to the fitting device of a loom and particularly relates to a device for controlling tension dynamic balance of warp threads of the loom. The device comprises a resistance disc (5), a resistance rope (6), a spring (9) and a fixed bracket (7); the resistance rope (6) is connected with the resistance disc (5); the fixed bracket (7) is shaped like T or 7; two ends of a transverse rod of the fixed bracket (7) are connected with a stander (1) and a guide roller (8) respectively; the lower end of a vertical rod of the fixed bracket (7) is connected with a tension balance bracket (2); the vertical rod body is connected with a displacement adjusting device (4); one end of the resistance rope (6) is connected with the displacement adjusting device (4) and the other end thereof is connected with the external end of the tension balance bracket (2); the tail end of the external end of the tension balance bracket (2) is connected with a tension balance roller (12); and the tension balance bracket (2) is connected with the fixed bracket (7) by a spring displacement adjusting device (10) and the spring (9). The device achieves the object of dynamically adjusting balance, generates an error of less than 0.25 percent during the operation process, and has small swing amplitude and stable tension control.

Description

technical field

[0001] The invention belongs to an accessory device of a loom, and relates to a warp thread tension control device, in particular to a loom warp thread tension dynamic balance control device. Background technique

[0002] The warp tension adjustment device of the existing loom, especially the warp tension adjustment device in the elastic band weaving process, mostly adopts the mode of heavy hammer suspension to control the tightness of the tension, such as tensioning the friction resistance rope by hanging the weight on the swing frame, or by The warp wheel directly hangs the weight to generate damping to achieve the purpose of controlling the tension of the warp. Since the warp head of the warp head changes from large to small during the weaving process, it is necessary for the weaver to increase or decrease the weight of the weight in a timely manner according to the weaving experience to ensure the consistency of the warp tension. However, in the process ...
