Description

technical field [0001] The invention relates to a metal card clothing wrapping pressing arm. Background technique [0002] The card clothing on the licker-in roller is spirally wound up by a strip-shaped metal card clothing (also called card clothing rack) with a card clothing wrapping machine. During the winding process, the metal card clothing needs to have a certain tension, and it needs to be pressed The block presses the card clothing on the outer wall of the licker-in roller, so that the card clothing is wrapped tightly and arranged neatly, prolonging the service life of the card clothing.

[0003] However, the structural design of the metal card clothing wrapping pressing arm of the currently used card clothing wrapping machine is unreasonable. During the wrapping process, the pressing block is easy to loosen, which makes it impossible to continuously press the card clothing tightly on the licker-in roller. on the outer wall, resulting in insufficient wrapping of the card clothing, and even phenomenon such as creeping teeth and uneven arrangement, which will affect the service life of the card clothing and reduce the carding effect of the licker-in roller
