Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of yarn clamping plates for looms, and particularly relates to a yarn clamping plate for the left rapier loom. Background Technology
[0002] Traditional looms use a rapier to guide yarn through a clamping section, causing the yarn to interweave into a fabric. Currently, rapier yarn guiding suffers from numerous errors when alternately guiding yarns with varying densities and cross-sections, resulting in low loom operating rates. During weaving, this leads to yarn stretching, deformation, breakage, and slippage. Research indicates that the insufficient elasticity caused by the thickness of the clamping plates contributes to this problem. Utility Model Content
[0003] The purpose of this invention is to propose a left rapier yarn clamping plate for a rapier loom, which aims to solve the technical problem that the existing yarn clamping plates are too thick and lack elasticity, causing the yarn to be easily stretched and deformed during weaving, resulting in breakage and slippage.

[0005] The housing comprises a housing and a first clamping piece, the housing being provided with a second clamping piece, the first clamping piece being mounted on the housing and positioned opposite to the second clamping piece, the second clamping piece being provided with a second clamping portion, forming a clamping space between the first clamping piece and the second clamping portion, the second clamping portion being 0.5 mm thick. <H<2.5mm。
[0006] Furthermore, the first clamping piece is provided with a first clamping part, and a clamping space is formed between the first clamping part and the second clamping part. The first clamping part is provided with a groove, and the second clamping part is provided with a protrusion that cooperates with the groove. When the first clamping piece is installed on the housing, the protrusion is located in the groove.
[0007] Furthermore, the first clamping part is provided with a limiting groove, and the second clamping part is provided with a limiting post that cooperates with the limiting groove. When the first clamping piece is installed on the housing, the limiting post is located in the limiting groove.
[0008] Furthermore, the second yarn clip is integrally molded with the shell.
[0009] Furthermore, the second clamping part is made of silicon manganese spring steel.
[0010] Furthermore, a guide portion is provided at one end of the second yarn clip, and the guide portion is a pointed and curved shape.
[0011] Further, a first connection hole is provided on the first yarn clamping piece, and a second connection hole matching with the first connection hole is provided on the second yarn clamping piece. A connecting piece sequentially passes through the first connection hole and the second connection hole to mount the first yarn clamping piece on the housing.
[0012] Further, a fixing column is provided on the second yarn clamping piece, and one end of the fixing column abuts against the first yarn clamping piece.
[0013] The beneficial effect achieved by the present utility model is that the thickness of the second clamping portion is set to 0.5mm < H < 2.5mm, so that the second clamping portion generates sufficient elastic force, making it difficult for the yarn to be stretched and deformed when entering or sliding out of the clamping space, and reducing the phenomena of yarn breakage and slippage.
