Drafting frame and operating process

Abstract

The invention relates to a drafting frame. The drafting frame comprises two underframes, warp beam supports, a drafting bracket, pull ropes, harness wire brackets, reed supporting rods, a warp thread supporting rod, reed supporting plate movable brackets and warp beam limiters, wherein a warp beam limiter is arranged at the rear end of each underframe of the drafting frame, and each warp beam support is arranged behind the warp beam limiter; warp threads are arranged in each warp beam support; the drafting bracket is arranged on the underframes; the brackets are arranged on the top of the drafting bracket, and a reed supporting plate is placed in the brackets; rear supporting rods are arranged on the rear side of the middle upper part of the drafting bracket, hooks are arranged on the rear supporting rods, and the pull ropes are arranged on the hooks of the rear supporting rods to lift up the warp thread supporting rod; the drafting bracket is supported by the supporting rods, and two harness wire brackets are sleeved on each supporting rod; and one reed supporting plate movable bracket is arranged between an upper harness wire bracket and a lower harness wire bracket on each supporting rod on the outer side of the drafting bracket. By designing the structure, compared with another drafting frame with the same type, the drafting frame is easier to operate, and is wider in application.

Description

technical field [0001] The invention relates to the field of drawing-in equipment, in particular to a drawing-in frame and an operating process. [0002] Background technique [0003] Drawing-in is an important front-end production process of fabric weaving, and the efficiency and quality of drawing-in directly affect the level of weaving efficiency. The existing heald threading device is mainly composed of a weaving beam support and a heald support. When in use, the weaving beam is placed on the weaving beam support, the heald is placed on the heald support, and then the warp yarn on the weaving beam is threaded according to the design requirements. on the heddle. Because the warp yarns of this kind of heald drawing device are in a relaxed state when drawing healds, the warp yarns are easy to be confused when drawing healds, making it difficult for the operator to identify, and the positions of the healds and the fixed warp pieces are fixed, so the heald drawing equipment...

Problems solved by technology

Because the warp yarns of this kind of heald drawing device are in a relaxed state when drawing healds, the warp yarns are easy to be confused when drawing healds, making it difficult for the operator to identify, and the positions of the healds and the fixed warp pieces are fixed, so the heald drawing equipment cannot be adjusted due to the size of the operator. Therefore, the working conditions of the operator are poor and the work efficiency is low. In addition, there are slow speed of the upper shaft and high labor intensity of the upper shaft. More than three people are required for the upper shaft, and the warp yarn is easily broken when the shaft is upper A series of defects such as, therefore urgently need to improve it, for this reason someone proposes to use application number as CN00204068.9 such as figure 1 The structure shown in the heald threading machine is used to solve these problems. The structure is composed of a movable seat, a weaving shaft support fixed on the seat, a menopause film fixed on the seat, and a heald support. , wherein the heald support is mainly composed of a pair of inverted L-shaped brackets fixed on the seat, and a beam placed on the bracket. A set of heald clips is provided on the left and right sides of the beam. There are fewer warp breakages and low labor intensity on the upper shaft, which can meet the needs of operators of different sizes. However, the reed bench used for reeding is an independent stool, so the reed to be threaded must be placed by the wall, which is easy Falling down will cause damage to the reed, and because the reed bench is set separately, it takes up a lot of space and will affect the overall environment of the drawing-in area. The reed bench must be moved to the side of the heald frame to reposition the reed, which will greatly affect the efficiency of heald threading. In addition, the screws of the heald bracket are ordinary screws, so a wrench is needed to screw the pair of healds The height of the supporting rod is adjusted, so you need to find a wrench to adjust it, which not only wastes time, but also affects the efficiency of threading
