Variable-diameter anti-slip textile conveying roller

Abstract

The invention relates to the textile technical field, in particular to a variable-diameter anti-slip textile conveying roller. The conveying roller comprises a rotating shaft, an electromagnet is fixedly connected to the middle of the rotating shaft, uniformly distributed springs I are fixedly connected to the outer side of the rotating shaft, clamping blocks movably connected with the inner wallof the rotating shaft are fixedly connected to the outer sides of the springs I, magnetic blocks I are fixedly connected to the middles of the clamping blocks, the outer side of the rotating shaft ismovably connected with a conveying roller body, and clamping grooves are evenly distributed in the inner wall of the conveying roller body. According to the variable-diameter anti-slip textile conveying roller, through cooperative use of a rubber ring and piston blocks, when the conveying device is used, the electromagnet is powered on, the piston blocks can move outwards under the mutual repulsion acting force of the electromagnet and magnetic blocks II, electrorheological fluid is extruded outwards, the rubber ring is expanded, and the rotating radius of the conveying roller body is effectively increased, so that attachment of the conveying roller body and cloth can be effectively guaranteed, the effect of preventing the cloth from slipping is achieved, and wrinkling of the cloth is effectively avoided.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a variable-diameter anti-slip textile transmission roller. Background technique [0002] The materials used for coloring in ancient China can be divided into mineral pigments and plant dyes, among which the latter is the main dye in ancient times. Mineral pigments are colored by adhesives to make them adhere to the surface of the fabric, but the color is easy to fall off when it meets water. This is not the case with vegetable dyes. When dyeing, the pigment molecules change the color of the fibers through affinity with the fabric fibers. Although the dyed colors are washed by the sun, they are not easy to fall off or rarely fall off. [0003] Most of the current textile fabrics are conveyed to the next step by conveying rollers after dyeing, but because the current conveying rollers are fixed in shape, after a long time of use, the conveying rollers can no longer be closely atta...

Problems solved by technology

[0003] Most of the current textile fabrics are conveyed to the next step by conveying rollers after dyeing, but because the current conveying rollers are fixed in shape, after a long time of use, the conveying rollers can no longer be closely attached to the fabric, resulting in Looseness often occurs during the fabric process, resulting in folds in the fabric, which affects the later use of the fabric
