Description

Multi-warp strand weaving method, weaving equipment and heald frame device

Technical field

The invention belongs to the technical field of textile fabrics, and particularly relates to a multi-warp strand weaving method, weaving equipment and heald frame device.

Background technique

Known as the country of silk, China has a long history of silk production and is famous for the development and evolution of various fabric structures. Chinese textiles not only reflect China's historical wisdom and culture, but also provide valuable resources for today's human fabric consumption and provide a reference for the development of functional textiles.

Gulu is an ancient textile known for its soft, thin, breathable texture and high quality. Unlike the regular cross-over of a plain weave, the warp threads are twisted and twisted into a series of figure eights, while the weft threads pass through the gaps thus formed, resulting in a strong and open mesh. Therefore, the size and structure are stable and not easy to deform, which lays the foundation for the durability of Luo clothes; the open mesh provides pores, which also allows air and light to pass through the fabric more easily, bringing a comfortable wearing experience.

Traditional leno fabrics usually have a structure of two to four twisted warp threads. In addition, webbing fabrics can be divided into webbing fabrics with fixed twisting groups and webbing fabrics without fixed twisting groups. In the weaving process of fabrics without fixed twist groups, each group of warp threads will be twisted with another group of warp threads. Among them, the four-warp twist without fixed twist groups is the most complicated. However, traditional gibbon weaving is usually done manually by weavers based on their personal skills, and most of the weaving methods and gibbet weaving equipment have been lost.

Existing weaving equipment mainly includes a bracket, a single heald frame installed on the bracket, and a beating knife. Usually, the weaving equipment can only weave winches with a single structure, and the weaver needs complicated operations during the weaving process. The speed is slow and the production efficiency is low.

The first heald wire 10 in the second heald frame 12 is fixed at the No. 3 position of the bottom bar, and the second heald wire 10 is fixed at the No. 7 position of the bottom bar.

The first heald 10 in the third heald frame 13 is fixed at the No. 2 position of the bottom pole, and the second heald 10 is fixed at the No. 6 position of the bottom pole.

The first heald 10 in the fourth heald frame 14 is fixed at the No. 4 position of the bottom pole, and the second heald 10 is fixed at the No. 8 position of the bottom pole.

It can be seen from the fixed position of each heald 10 mentioned above that two adjacent healds 10 on each heald frame are spaced 3 positions apart, and the eight healds 10 are on a plane parallel to the heald frame, such as the first heald frame. The projections do not overlap and are evenly spaced. The heald eyes of 8 healds and 10 healds are on the same straight line.

In the above description, two healds 10 are fixed on the bottom bar of each heald frame. In practical applications, the length of the bottom bar of each heald frame can be extended from left to right to the required length, such as the designed width. wide, so that more healds 10 can be added to the bottom pole, the number of added healds 10 can be a multiple of 8, and the arrangement on the bottom pole of each heald frame can be the same as the original 8 healds. 10 are arranged in the same way, then the fabric woven using such a heald frame device has the same organizational structure; on the other hand, the number of added healds does not need to be a multiple of 8, and the arrangement can also be the same as the original healds. If different, the fabric woven using such a heald frame device has a different organizational structure.

In this embodiment, a specific implementation of the heald frame device is simply explained by taking the number N of heald frames as 4 pieces and the number M of healds as 8 (M is twice N) as an example. In some other embodiments, the number N of heald frames is not limited to 4 pieces, but can also be 3 pieces, 5 pieces, 6 pieces, etc., and the number M of healds may not be a multiple of the number N of heald frames. Specifically, it can be based on The organizational structure of the gauze fabric is designed flexibly.

Referring to Figure 1, further, the heald frame device of this embodiment also includes a transverse heddle pulling device, a longitudinal heddle lifting device and a guide device.

The transverse heddle pulling devices are respectively arranged on the left and right sides of the N heald frames, and are used to push and pull the heald frames in the left and right directions respectively. As shown in Figure 1, the transverse heddle device in this embodiment includes a plurality of pull ropes 21. One ends of the plurality of pull ropes 21 are respectively connected to the left and right rods of the four heald frames. In order to facilitate the holding or horizontal connection, The driving device (not shown) is fixed, and a stopper 22 can be fixed on the other ends of the plurality of pull ropes 21 respectively.

Longitudinal heald lifting devices are respectively arranged on the top sides of the N pieces of heald frames, and are used to lift and lower the heald frames in the up and down directions respectively. As shown in Figure 1, the longitudinal heddle lifting device in this embodiment includes a plurality of elastic hanging ropes 23, and the elastic hanging ropes 23 are, for example, springs. One end of the plurality of elastic hanging ropes 23 is connected to the top rod of the four heald frames respectively. In order to facilitate holding or fixing with the longitudinal driving device (not shown), the other end of the plurality of elastic hanging ropes 23 can be connected to a hanging rod 24 . In order to prevent the heald frame from skewing during the lifting process, the two ends of the top rod of each heald frame can be connected to an elastic hanging rope 23 respectively. The other ends of the two elastic hanging ropes 23 are connected to the two ends of the same hanging rod 24. Ends.

In some other embodiments, the longitudinal heddle lifting device can also be disposed on the bottom side of the N heald frames respectively, or simultaneously on the top and bottom sides of the N heald frames, which will not be explained here.

In the heald frame device of the present invention, the moving driving mode of each heald frame can be manual, semi-automatic or fully automatic. In the absence of a transverse heddle lifting device and a longitudinal heddle lifting device, the up and down or left and right movement of the heald frame can also be realized by directly moving the heald frame.

The guide devices are arranged on the left and right sides of the N heald frames. As shown in Figure 1, the guide device in this embodiment includes two guide plates 25. The two guide plates 25 are symmetrically arranged on the left and right sides of the four heald frames. The guide plates 25 are provided with four guide plates 25 extending in the left and right directions. The left and right sides of the four heald frames, such as the left rod and the right rod, are respectively accommodated in the guide groove 26. The guide plate 25 is provided with perforations at positions corresponding to the guide grooves 26 for the pull ropes 21 in the transverse draw heddle device to pass through.

In this embodiment, the cross section of the guide plate 25 can be L-shaped, but the invention is not limited thereto. In other embodiments, the guide plate 25 can also be in other shapes, such as a flat plate, as long as it can be configured to extend left and right. The structure in which the guide groove is located is feasible.

The guide device plays a guiding role in the action process of the heald frame: when the boom 24 above the top rod of a certain heald frame is pulled upward, the elastic rope 23 connected to the boom 24 drives the heald frame to move along the guide groove 26. When the pull rope 21 on the left or right rod of a certain heald frame is pulled to the left or right, the heald frame moves to the left or right along the guide groove 26.

Referring to Figure 3, in this embodiment, the heald frame is an inverted U-shape, including a push rod and a left and right rod connected to both ends of the push rod. The healds 10 are fixed on the push rods, and the healds 10 are The silk eyes are facing downward. The height of the heald frame is 0.4-1 times the height of the heald wire 10. Preferably, the height of the heald frame is 0.5 times the height of the heald wire 10. Using a heald frame of this shape, the height of the heald frame, that is, the height of the left and right rods of the heald frame, can be relatively short.
