Description

Technical Field

[0001] The utility model relates to the field of air-changing yarn manufacturing, in particular to a guide roller component used for dyeing. Background Art

[0002] The air-transformed yarn uses special processing technology to produce the bumpy feel and soft touch of natural flax, while overcoming the wrinkle-proneness of natural flax. It is washable and easy to care for. It has a natural appearance, irregular surface tops, particles, bamboo effects and good color. It can be used for decorative fabrics (curtain fabrics, gauze fabrics, pillows, cushions, headscarves, gauze scarves, etc.) and fashion fabrics.

[0003] In the prior art, when manufacturing polyester air-change yarn products, in order to make the product color have a variety of options, the polyester air-change yarn needs to be dyed. At present, when the polyester air-change yarn is dyed, the dyeing quality is poor, and the dye is easy to precipitate after standing, which can easily lead to uneven dyeing. Application No.: CN202122597176.8 proposes a dyeing device for polyester air-change yarn production to solve the above defects. However, when it dyes the air-change yarn, the air-change yarn is simply guided by a guide roller into the dyeing box for immersion dyeing. Since the path and time of the air-change yarn in the fuel are limited, only immersion may cause the defect of incomplete dyeing. Summary of the invention

[0004] In order to make the dyeing of air-changing silk more thorough and efficient, the utility model proposes a guide roller assembly for dyeing, whose structure includes: a reciprocating traction device and a plurality of wire guide rollers arranged in sequence according to the wire path, the reciprocating traction device includes a strip plate, the strip plate is provided with a plurality of wire threading holes arranged along its length direction, and a reciprocating motion device is fixed to one end of the strip plate; the wire guide roller includes a main shaft and a roller sleeve sleeved on the outside of the main shaft, the roller sleeve is provided with a plurality of annular wire grooves, and the bottom of the wire grooves is a rough surface.

[0005] Preferably, the reciprocating motion device includes a motor as a power source and a crank-connecting rod mechanism connecting the motor and the strip.

[0006] Preferably, the roller sleeve is made of metal or plastic.

[0007] Preferably, the bottom of the wire groove has an orange peel texture or a frosted surface.

[0008] Preferably, the number of the wire threading holes is equal to the number of the wire slots, and the width of each wire slot is greater than the aperture of the wire threading hole.

[0009] When the utility model is in use, multiple strands of air-variable yarns are passed through the strips of the reciprocating traction device and are clamped in the corresponding wire grooves on each wire guide roller. During the travel of the air-variable yarns, each strand of the air-variable yarn is reciprocated and pulled in a direction perpendicular to the travel direction. Each strand of the air-variable yarn is rubbed within the limited width of each wire groove. Since the surface of the bottom of the wire groove that contacts the air-variable yarn is a rough surface, the movement simulates the process of hand twisting, thereby helping the dye to dye the air-variable yarn better and faster. The utility model realizes efficient dyeing of the air-variable yarn. BRIEF DESCRIPTION OF THE DRAWINGS
