Abstract

A replaceable needle plate assembly, which relates to the field of textile machinery, and to a replaceable needle plate assembly in particular. A replaceable needle plate assembly with simple structure, replacement convenience and assembly convenient is provided, which comprises a base plate, wherein a plurality of through holes are arranged on the substrate; a needle seat for placing a lancet isdetachably arranged in the through hole; the needle seat comprises a seat body; the seat body is provided with a middle hole; and at least one circle of flexible ring bodies is arranged in the middlehole. The lancet comprises a needle body, wherein the head part of the needle body is provided with a needlepoint, at least one circle of ring groove is arranged at the tail part, and the ring body isadaptively arranged in the ring groove. The through hole is provided with internal threads, the seat body is provided with external threads, and the seat body is connected in the through hole throughthreads. The device is convenient to process and is labor saving.

Description

technical field [0001] The invention relates to the field of textile machinery, in particular to a replaceable needle plate assembly. Background technique [0002] Needle boards are widely used in the field of textile machinery, such as punching holes such as hemp felt boards, improving air permeability and strength, etc. In the needle board of the prior art, the needles and the base plate are not detachably connected. When the needles on the base board are damaged and broken, the needle board needs to be replaced as a whole, which costs a lot. There is also a method of manually knocking the needles into the pinholes of the substrate; however, manual knocking in and out is time-consuming and laborious, and the work intensity is high. Moreover, knocking on the pricker easily deforms the pricker and causes damage. Contents of the invention [0003] Aiming at the above problems, the present invention provides a replaceable needle plate assembly which is simple in structure,...
