The utility model provides a roller for fabric indigo oxidation, which is suitable for oxidation of fabric indigo with larger elasticity.
Description
Technical Field
The utility model relates to the technical field of dyeing equipment, in particular to a roller for indigo oxidation of fabrics.
Background
Denim is a traditional garment fabric which is not weak for a long time, and is manufactured by indigo dyeing, the indigo dyeing is a special dyeing process, the indigo belongs to one of the lowest affinity dyes, the indigo can be gradually deepened only by the processes of soaking the dyes for multiple times, rolling and ventilating oxidation, and the color is deepened for more times, so the basic requirement of the indigo dyeing is to use air for multiple oxidation, the oxidation method is an important link of dyeing, a plurality of conveying rollers are usually arranged on a ventilation frame, the fabric is conveyed back and forth for a long distance by the traction of the conveying rollers, the fabric is contacted with air for a long time in the conveying process to realize oxidation, the diameter of the existing conveying rollers is smaller and is not more than 120mm, the distance between the front and rear conveying rollers is far, the fabric is mainly conveyed by the traction of the tension formed during rotation, and the problem of conveying woven fabric with small elasticity is not solved, however, when a knitted fabric having a large elasticity is conveyed, problems such as deformation and curling occur, which affect the quality of the product.
Disclosure of Invention
The utility model aims to solve the technical problem of providing a roller for fabric indigo oxidation, which is suitable for oxidation of fabric indigo with larger elasticity and can solve the defects of the prior art.
The technical scheme of the utility model is as follows: the roller for the fabric indigo oxidation comprises a roller and a main shaft, wherein the main shaft and the roller are coaxially arranged to drive the roller to synchronously rotate, the roller is a hollow cylinder, the diameter of the roller is not less than 600mm, and ventilation holes are distributed in the surface of the roller.
The air suction device comprises an air suction pump, an air pipe extending into the roller through the hollow shaft, an air suction opening is formed in the air pipe, the air suction pump is connected with the air pipe, and negative pressure is formed in the roller by pumping air to the air pipe.
The air pipe is positioned in the roller and is parallel to the axial lead of the roller, the air suction opening is arranged along the length direction of the air pipe part positioned in the roller, the air suction opening is provided with a horn-shaped air suction nozzle, and the opening of the air suction nozzle faces the direction of the contact of the fabric and the roller.
Further, the outer surface of the roller is provided with uneven patterns.
Through the implementation of the utility model, the rollers are driven to rotate by the main shaft, the fabric is conveyed by winding around the surfaces of the rollers, the diameters of the rollers are larger (not smaller than 60 mm), the distance between two adjacent rollers is small, the adjacent rollers are almost tangent, the fabric is wrapped on the outer surfaces of the rollers in a large area, and enters the next roller from a front roller through a short distance, so that the fabric is driven to convey mainly by virtue of the friction force generated by the rollers, the fabric with small conveying elasticity is not influenced, meanwhile, the fabric is also suitable for the conveying of the knitted fabric with low tension and high elasticity, and due to the ventilation holes distributed on the surfaces of the rollers, when the fabric is wrapped on the outer surfaces of the rollers, air can contact with the fabric through the ventilation holes, and the oxidation of the fabric dye is not influenced.

Detailed Description
The embodiment of the utility model comprises the following steps: as shown in fig. 1 to 4, a roller for indigo oxidation of fabric comprises a roller 1 and a main shaft 2, wherein the main shaft 2 and the roller 1 are coaxially arranged to drive the roller 1 to synchronously rotate, the roller 1 is a hollow cylinder with a diameter of 600mm or 800mm or 1000mm, vent holes 3 are distributed on the surface of the roller 1, a plurality of rollers are matched for use when in use, the distance between two adjacent rollers is small, the adjacent rollers 1 are almost tangent, the fabric 4 is wrapped on the outer surface of the roller 1 in a large area, and enters the next roller from the front roller through a short distance, so that the fabric is driven to be conveyed mainly by the friction force generated by the rollers, the conveying of the fabric with small elasticity is not influenced, the conveying of the fabric with large elasticity is also suitable for the conveying of the fabric with large elasticity, because the vent holes 3 are distributed on the surface of the roller 1, air can contact with the fabric through the vent holes 3 when the fabric is wrapped on the outer surface of the roller 1, does not affect the oxidation of the fabric dye.
As an optimization, including the device that induced drafts, 1 both ends of cylinder are provided with vexed head 5, main shaft 2 is the hollow shaft of being connected with vexed head 5, the device that induced drafts includes aspiration pump 6, stretch into the tuber pipe 7 of 1 section of thick bamboo of rolling through the hollow shaft, be equipped with inlet scoop 8 on the tuber pipe 7, aspiration pump 6 links to each other with tuber pipe 7, aspiration pump 6 tuber pipe 7 is bled to forming the negative pressure in the cylinder 1, circulation of air accelerates, improve the oxidation rate of fabric dyestuff, negative pressure forms the adsorption affinity on the surface of cylinder to fabric 4 simultaneously, produce stronger frictional force when making to carry, further do benefit to the no tension of the great fabric of elasticity and carry.
Preferably, the air pipe 7 is located inside the roller 1 and is parallel to the axial lead of the roller, the air suction opening 8 is arranged along the length direction of the air pipe part located inside the roller 1, the air suction opening 8 is provided with a horn-shaped air suction nozzle 9, the opening of the air suction nozzle 9 faces the direction in which the fabric 4 is contacted with the roller 1, so that the air suction nozzle 9 sucks air opposite to the fabric 4, air is favorably concentrated to circulate to the fabric, the oxidation effect and the pressure increase of the fabric are better realized, and the effect of enhancing the surface friction force between the fabric and the roller 1 is further achieved.
Preferably, the outer surface of the roller 1 is provided with an uneven pattern, so that the friction force during conveying is further increased, and the non-tension conveying of the fabric with larger elasticity is further facilitated.
