Height-adjustable needle seat structure

Abstract

The invention discloses a height-adjustable needle seat structure. The height-adjustable needle seat structure comprises a base and a needle, wherein the needle is arranged on the base, and the needle comprises a needle head, a needle body and a needle connecting part; the base comprises a base body and a bottom cover, and a connecting hole which corresponds to the needle connecting part is formed in the base body; a gap is formed between the base body and the bottom cover after the bottom cover and the base body are closed, a sleeve and a bolt are arranged on the bottom cover, the sleeve is in threaded connection with the bolt, a connecting stud which corresponds to the bolt is arranged on the base body, and the gap between the base body and the bottom cover can be adjusted to be small / large by rotating the bolt to move to the inside / outside of the connecting stud. By using the scheme of the height-adjustable needle seat structure, operating personnel can conveniently replace the bent needle, the service life of a needle seat is prolonged, and additionally, the height of the needle seat structure can be freely adjusted.

Description

technical field [0001] The invention relates to the field of textile instruments, in particular to a height-adjustable needle seat structure. Background technique [0002] In the existing textile industry, when dealing with sisal, jute, and linen fabrics, single-row needle holders are generally used, and because the hardness of the needles is weak, it is easy to break or block the needles during use, which affects the use of the needle row. life. Moreover, there must be a certain gap between the needles of the existing needle row, which will easily lead to a large contact area between the needles, which will affect the quality of fabrics such as hemp slivers, such as making the carded hemp slivers uneven in thickness . In addition, the number of needle rows that need to be used in the prior art is relatively large. During the operation of textile equipment, position deviation between multiple needle rows is prone to occur, resulting in changes in the relative positional re...

Moreover, there must be a certain gap between the needles of the existing needle row, which will easily lead to a large contact area between the needles, which will affect the quality of fabrics such as hemp slivers, such as making the carded hemp slivers uneven in thickness

In addition, the number of needle rows that need to be used in the prior art is relatively large. During the operation of textile equipment, position deviation between multiple needle rows is prone to occur, resulting in changes in the relative positional relationship between needles, which may lead to fabric damage. inconsistent texture
