Description

Technical Field

[0001] The utility model relates to the technical field of non-woven fabric production, in particular to a non-woven fabric dyeing device. Background Art

[0002] Non-woven fabric, also known as non-woven fabric or non-woven fabric, is a sheet, web or pad made of oriented or randomly arranged fibers combined with each other through friction, cohesion or bonding, or a combination of these methods. It is made of textile staple fibers or filaments that are oriented or randomly arranged to form a web structure, and then reinforced by mechanical, thermal bonding or chemical methods. Non-woven fabric is a new generation of environmentally friendly materials, with the characteristics of moisture-proof, breathable, flexible, lightweight, non-combustible, easy to decompose, non-toxic and non-irritating. If placed outdoors, its maximum life span is only 90 days after natural decomposition; if placed indoors, it will decompose within 8 years, and it is non-toxic and harmless when burned, and does not pollute the environment. Commonly used raw materials for the production of non-woven fabrics include chemical fibers such as polypropylene resin, polyester fiber, polyester fiber, etc. These materials can be decomposed naturally and will not pollute the environment.

[0003] A dyeing device for non-woven fabric processing described in publication number CN220724538U includes a dyeing box, one side of the dyeing box is fixedly connected to a support plate, the top of the support plate is fixedly connected to a drying box, and the top of the dyeing box is rotatably connected to two guide rollers. The utility model has a reasonable structural design. Through two left and right knocking and vibration components, the incoming non-woven fabric and the outgoing non-woven fabric can be knocked and vibrated, which can not only shake off the bubbles attached to the surface of the non-woven fabric that has just entered, and reduce the influence of the bubbles on the dyeing when it just enters, but also shake off the excess dye liquid on the outgoing non-woven fabric, which is beneficial to the subsequent drying work. Through multiple rotating rollers, the time that the non-woven fabric is located in the drying box is extended, and the front and back sides of the non-woven fabric can be fully and evenly contacted with the hot air sprayed by the nozzle, thereby greatly improving the uniformity of drying, making the drying effect better and more efficient. However, the prior art still has defects:

[0004] 1. In the prior art, two left and right knocking and vibration components are used to knock and vibrate the incoming non-woven fabric and the outgoing non-woven fabric, so that the bubbles attached to the surface of the non-woven fabric that has just entered can be shaken off, reducing the influence of the bubbles on the dyeing when it just enters. However, the shaking is not thorough enough to eliminate the bubbles, and there will still be bubbles remaining that affect the dyeing quality.

[0005] 2. In the prior art, the excess dye liquid on the non-woven fabric is shaken off by beating the vibration component, which is beneficial to the subsequent drying work. However, the efficiency of vibration in shaking off the dye liquid is low, and the effect of removing excess dye liquid is poor. Utility Model Content
