Problems solved by technology

[0002] The GA747 loom does not have an independent waste edge mechanism. If there is no plain weave in the fabric during weaving, it is often necessary to reserve the first two pages of the heald frame as the weaving edge. When the frame is not enough
At the same time, on the GA747 loom, the opening time of the waste edge is the same as the opening time of the ground weave, which necessarily requires the same time for the sword retraction and heald leveling time to avoid weft shrinkage, which is unfavorable for weaving weft elastic fabrics and limits the weaving process. Affect the overall performance of the loom

Embodiment

[0030] A waste edge mechanism of a loom is mainly composed of a heald frame piece chute, a heald frame piece, a heald frame piece support, a heald frame transmission shaft and a transmission mechanism.

[0031] 1. Heald frame transmission shaft and transmission part

[0032] The schematic diagram of the transmission mechanism of the independent waste edge mechanism is as follows figure 1 shown. The first gear 2 is installed on the central axis 1 of the loom, and the first gear 2 transmits the second gear 3. A connecting rod 4 is installed on the second gear 3. The other end of the connecting rod 4 is connected with the swing rod 5. On the swing rod 5 There is a long slot, and the position of the connecting rod 4 on the swing rod 5 can be adjusted. With the rotation of the central shaft 1, the gear drives the connecting rod 4 to reciprocate, thereby driving the swing rod 5 to swing up and down. The swing rod 5 is fixed on the heald frame transmission On the shaft 6, through t...

Abstract

The invention discloses a waste edge mechanism of a loom. The waste edge mechanism comprises a heald frame piece sliding groove, a heald frame piece, a heald frame piece support foot, a heald frame transmission shaft and a transmission mechanism. The waste edge mechanism is specially used for the loom GA747, and the overall performance of the loom is improved; after the independent waste edge mechanism, two heald frames are not needed to be reserved to knit a waste edge and wring the edge, in another word, the two heald frames are added on the previous basis, and the design range of a fabric tissue is broadened; for knitting broadwise elastic fabrics, the independent waste edge mechanism can effectively prevent loop weft; four heald frames in the waste edge mechanism are replaced with two heald frames, the waste edge mechanism is directly changed to be a plain weave opening mechanism, and besides, the plain weave opening mechanism belongs to an active type opening mechanism; the waste edge mechanism is simple in structure, steady and reliable in operation and capable of being used for production of a high-speed loom and knitting plain weave fabrics with less total warp roots.

Description

technical field [0001] The invention specifically relates to a waste edge mechanism of a loom, which improves the overall performance of the loom; after using the independent waste edge mechanism, it is no longer necessary to reserve 2 pages of heald frames, and weaving waste edges and twisted edges is equal to two more One-page heald frame expands the design scope of fabric weave; the independent waste edge mechanism can effectively prevent weft shrinkage for weaving elastic fabrics; replace the four heald frame pieces in the waste edge mechanism with two-page heald frames, which can be used as plain weave The shedding mechanism is used, and this plain weave shedding mechanism is a positive shedding mechanism, which has a simple structure, stable and reliable operation, and can be used in the production of high-speed looms to weave plain weave fabrics with a small total warp. Background technique [0002] The GA747 loom does not have an independent waste edge mechanism. If ...
