Fixed-length forming matrix warp let-off device

Abstract

The invention discloses a fixed-length forming matrix warp let-off device, which comprises a frame, a movable rack, a driving device and a plurality of toothed plates, wherein a guide rail is arrangedon the frame, and the movable rack is movably mounted on the guide rail; the driving device is mounted on the frame and used for driving the movable rack to move along the guide rail; two arc-shapedgrooved seats are arranged on the movable rack, extend in the vertical direction and are arranged at intervals in the horizontal direction; two ends of the toothed plate are clamped on the two arc-shaped grooved seats, and each toothed plate is provided with a first axis and can rotate around the first axis; each toothed plate is provided with tooth grooves; The driving device is connected to themovable rack via a pressure sensor; the pressure sensor is used for measuring pressure between the driving device and the movable rack. According to the invention, the length of a tension yarn on thetwo sides of the toothed plates is changed, so that the tension generated by the tension yarn on the two sides of the toothed plates is changed and tends to be balanced, and the tension of two warps connected with the two ends of the tension yarn tends to be balanced.

Description

technical field [0001] The invention relates to a fixed-length forming matrix warp let-off device, which belongs to the technical field of textile machinery. Background technique [0002] When developing new models of aerospace products, most of them are trial-manufactured and developed products, with various varieties but small quantities. If the continuous warp let-off is still adopted, it is easy to cause warp yarn waste and increase the raw material cost of the product, and the yarn has a long path from the warp beam to the weaving fell, and there are many accessories passing through, which is easy to cause yarn wear. At the same time, the preparation time for continuous warp feeding is long, it is difficult to meet the flexibility of multi-variety and small-batch product preparation, and the overlap between yarns is serious, which greatly limits the improvement of weaving efficiency. [0003] For multi-variety and small-batch products, the fixed-length forming method i...

AI Technical Summary

Problems solved by technology

In the existing fixed-length forming method, due to the limitation of the warp arrangement device, the uppermost layer and the lowermost layer of the tension line form a certain angle, which will cause problems such as uneven warp tension, unclear opening, and easy damage to the yarn.
