Problems solved by technology

[0003] The roller has high requirements on the driving force. If the roller rotates too fast or the torque is too large, the fiber will be strained. If the roller rotates too slowly or the torque is too small, the processing effect will be poor and the processing efficiency will be affected.

Abstract

The invention provides a magnetic roller. The magnetic roller comprises a roller, wherein two ends of the roller are pivoted into a roller support; magnetic clutch devices are arranged at the two ends of the roller and in the roller support corresponding to the two ends; each magnetic clutch device is composed of a roller end face which is provided with a permanent magnet and a driving cake which is coaxially arranged in opposition to the roller end face, and provided with a permanent magnet; each magnetic pole connecting line of each two permanent magnets is arranged to be vertical to the axial line of the roller; and the magnetic poles at corresponding positions among the permanent magnets are opposite. By the adoption of the magnetic clutch devices which regard magnetism as a drive device of the roller, the roller when being overloaded can actively and temporarily disconnect to the drive source to prevent conveyed fibers from pulling damage caused by enforced rotation.

Description

technical field [0001] The invention relates to the field of textile machinery, in particular, a roller using a magnetic clutch device. Background technique [0002] Cylindrical rotating parts that play the roles of feeding, drafting, and output in textile machinery have the meaning of rollers and shafts. Widely used in drafting, carding, conveying and other mechanisms. According to the role played, it is divided into drafting roller, feeding roller, pressing roller, working roller and so on. The drafting roller is the main part of the drafting mechanism of the spinning machine. The upper roller and the lower roller are paired to form a roller nip, which holds the yarn for drafting. The quality of the rollers affects the uniformity of the output sliver. Most of the top rollers used in spinning machinery are covered with elastic materials, commonly known as top rollers. There are also smooth rollers, called iron rollers or lightweight rollers, and individual machines als...
