A carding machine licker-in roller with cushioning needles

Abstract

The invention discloses a carding machine licker-in roller with buffer licker-in needles. The carding machine licker-in roller comprises a rotating shaft and a roller body. The outer wall of the middle of the rotating shaft is provided with spline protrusions. Spline grooves are formed in the inner side wall of a center through hole in the roller body. The rotating shaft is inserted in the center through hole of the roller body in a sleeved mode. The spline protrusions are inserted in the spline grooves in a sleeved mode. End covers are fixed to the two ends of the roller body. The spline protrusions in the middle of the rotating shaft are clamped between the two end covers. Annular grooves are formed in the two end faces of the roller body. The bottom faces of the annular grooves are provided with a plurality of connecting holes. Each end cover abuts against the corresponding end face of the roller body in a pressing mode and provided with an end cover connection annular groove. Annular sealing blocks are embedded in the annular grooves and the end cover connection annular grooves. According to the carding machine licker-in roller with the buffer licker-in needles, licker-in needle replacement and connection are convenient, the whole licker-in roller does not need to be replaced, and therefore the cost is reduced; in addition, the licker-in needles can contact and retract, so that it is ensured that the licker-in needles have the buffer effect when colliding with hard objects, damage to the licker-in needles is reduced, and the service life is prolonged.

Description

Technical field: [0001] The invention relates to the technical field of textile equipment, in particular to a carding machine licker-in roller with buffer needles. Background technique: [0002] In the existing cotton opener, carding machine and other equipment, the licker-in roller is an important part, which mainly separates the cotton wool from the lint. Generally, a rotating roller is fixed on the rotating shaft, and on the outer wall of the rotating roller The fixed needle, the needle and the rotating roller cannot be disassembled, so that after a period of use, the entire rotating roller is directly replaced when the needle is worn out, which is very troublesome and increases the cost. [0003] At the same time, the needles of the existing licker-in rollers are fixed and hard-connected. When hard objects touch the needles, the needles will be bent or worn, which will affect their service life. Invention content: [0004] The purpose of the present invention is to ad...
