Needle roller for carding machine and preparation method thereof

Abstract

A needle roller for carding machine belongs to a piece of equipment for carding machine in the cotton textile industry. The needle roller includes an aluminum pipe and a central axle; both ends of the aluminum pipe are sealed with flanges; the wall of the aluminum alloy pipe is opened with a aluminum hole; a steel needle is planted in the aluminum hole, which consists of a needle tip and a needle bar; the needle bar of the steel needle planted in the aluminum alloy pipe hole is adhered and integrated to the aluminum alloy pipe by super glue. The product quality is reliable; the needle roller and the needle tip have small coaxially and high co-straightness; the needle roller with the aluminum alloy as base structure is convenient in installation, has light weight, less energy consumption, high equipment manufacturing efficiency; in addition, the time for parking for maintenance is short, the carding quality is stable and unchanged, which is applicable to reconstruction of the current carding machines, and improves the performance and quality of the carding machines.

Description

technical field [0001] The invention belongs to equipment for a carding machine in the cotton spinning industry, in particular to a needle roller made of aluminum alloy, and also provides a preparation method for the needle roller for a carding machine. Background technique [0002] In the cotton spinning industry, the needle rollers of carding machines are commonly used for sawtooth licker-in rollers. The licker-in rollers are composed of racks. The teeth of the racks are easy to cause wear and have a short service life. In addition, the sharp angles of the serrated teeth are generally larger than the sharp angles of the comb needles, so it is not easy to pierce the cotton. The sharp edge of the rack will damage the fiber, the carding quality will decrease, and the production efficiency of the equipment will be low. The gear roller is made of steel plate, which is inconvenient to install, consumes a lot of energy, and takes a long time to stop for maintenance. Contents of ...
