Barbed nail roller assembly

Abstract

The invention discloses a barbed nail roller assembly which comprises a pipe shaft, a group of flanges and a wrapping plate, wherein the flanges are arranged along with axial direction of the pipe shaft and are coaxial with the pipe shaft; the wrapping plate is fixed on the flanges to form a cylinder; barbed nails are uniformly arranged on the wrapping plate; each flange has a regular pyramid structure; the wrapping plate comprises a plurality of split bodies which are exactly divided by the arris number of the regular pyramid; the split blocks are used for forming the side surface of the cylinder; and the barbed nails are spherical crown tapered barbed rivets. The barbed nail roller assembly has high motion precision, high reliability and long service life.

Description

technical field [0001] The invention relates to a spike roller assembly, comprising a tube shaft, a group of flanges arranged axially along the tube shaft and coaxially with the tube shaft, and cladding plates fixed on the flanges to form a column , where spikes are evenly arranged on the cladding board. Background technique [0002] The known nailing roller comprises a tube shaft, a group of circular flanges arranged axially along the tube shaft, and cladding plates connected to the flanges, wherein the cladding plates cooperate with the flanges to form flanges as the bottom, The cladding board is a cylindrical body on the side, and radial spikes are arranged on the cladding board, which is mainly used as a basic functional part for cleaning and loosening materials in the complete set of cotton and linter processing equipment. The wrapping boards are mostly preset with thorn holes, and the conical thorns are riveted on the wrapping boards. This process can easily cause def...

AI Technical Summary

Problems solved by technology

The wrapping boards are mostly preset with thorn holes, and the conical thorns are riveted on the wrapping boards. This process can easily cause deformation of the wrapping boards, and the arc surface structure of the wrapping boards makes it difficult to deform the wrapping boards. Correction, so that the radial runout error of the final nailing roller assembly is too large, and it is difficult to meet the technical requirements of the radial runout of the nailing roller assembly being less than 2.5mm

In addition, during the cladding correction process, it is easy to cause skewing or loosening of the thorns, and often the arrangement of the thorns will be very irregular after the production of a thorn roller assembly

The important thing is that once the cladding plate is deformed, the fixed holes reserved on the cladding plate do not correspond to the fixing holes on the corresponding flange, and the fixing holes have to be drilled, which reduces work efficiency and affects the structural strength and accuracy after assembly

[0003] In addition, the tapered spikes are easy to cause damage to wires and fibers, which not only affects the quality of processed cotton or linters, but also has poor opening effect
