Description

Technical Field

[0001] The utility model relates to the field of looms, in particular to a guide pressing mechanism of a loom. Background Art

[0002] Loom, the common name for loom, the earliest loom was a squat loom (also called waist loom) that was used while sitting on the ground. The method of use was to step on the wooden stick of the loom's warp, hold the wooden knife for beating the weft in the right hand to tighten the weft, and the left hand was in the posture of throwing the weft and guiding the weft. This foot-pedal waist loom had no frame. One end of the cloth winding shaft was tied to the waist, and both feet stepped on the warp shaft at the other end to tension the fabric. The warp yarns were divided into two layers according to odd and even numbers with the warp dividing stick, and the warp yarns were lifted with the heald lifting rod to form a shed, and the weft was guided with a bone needle and the weft beating knife was used to beat the weft. The most important achievement of waist loom weaving was the use of the heald lifting rod, warp dividing stick and weft beating knife. Although this loom was very simple, it already had three directions of movement: opening the fabric opening up and down, guiding the weft left and right, and tightening front and back. It was the ancestor of the modern loom.

[0003] When the loom is working, the introduced weaving thread needs to be guided and pressed to facilitate weaving. The existing guiding and pressing mechanism has a relatively fixed and rigid structure, and its openings are mostly horizontally facing backwards. For the weaving thread introduced from an inclined direction, such as from above, it may cause wear of the weaving thread, and may cause the weaving thread to break during weaving, affecting the normal operation of the loom, and has certain limitations.
