Dyeing device for non-woven fabric production

Abstract

The invention discloses a dyeing device for non-woven fabric production. The dyeing device comprises a base, a support, a machine box, an electric push rod and a top frame, wherein the support is fixedly connected to one side of the top of the base, the machine box is fixedly connected to the top of the support, the electric push rod is fixedly connected to the interior of the machine box, and anoutput shaft of the electric push rod movably penetrates through the bottom of the machine box and the top of the support and is arranged below the top of the support. According to the dyeing device,non-woven fabric can be immersed into dye through the electric push rod, and two rotating rollers can be kept rotating continuously under the driving of two stepping motors, so that the non-woven fabric is dyed more uniformly, and the problem that an existing dyeing device cannot be used for dyeing uniformly during dyeing is solved; and two extrusion rollers are driven by a linear module to move,and dye in the non-woven fabric can be extruded out, so that the situation that the drying time is prolonged due to excessive moisture in the non-woven fabric in the later drying process is avoided.

Description

technical field [0001] The invention relates to the technical field of non-woven fabric production equipment, in particular to a dyeing device for non-woven fabric production. Background technique [0002] Non-woven fabrics, also known as non-woven fabrics, are composed of oriented or random fibers. It is called cloth because of its appearance and certain properties. Non-woven fabrics are moisture-proof, breathable, flexible, light in weight, non-combustible, easy to decompose, non-toxic and non-irritating, rich in color, low in price, and recyclable. Features. For example, polypropylene pellets are mostly used as raw materials, which are produced by continuous one-step process of high-temperature melting, spinning, laying, and hot-pressing coiling. [0003] The authorized patent (publication number: CN106811887B) discloses a non-woven fabric dyeing device for garment production, including a dyeing box, a first slide rail, a first slider, a lifting mechanism, a first conne...

AI Technical Summary

Problems solved by technology

When the inventor realized this technical means, he found that the following defects were not well improved: 1. Since the non-woven fabric was directly wound on the first cylinder, the cylinder was connected with the non-woven fabric and then directly immersed in the dye, thereby dyeing , in the actual dyeing process, since the non-woven fabric layers are superimposed on each other, the non-woven fabric on the outer layer has a better dyeing effect, but the non-woven fabric on the inner layer has a poor dyeing effect when dyeing, and the colorant The entry speed is slow, which affects the dyeing effect; 2. Since the non-woven fabric needs to be dried after dyeing, and after the non-woven fabric is dyed, there is too much water inside, which greatly prolongs the drying time and increases the dyeing time. Cycle; 3. The soaking length of non-woven fabrics in the dyeing box is not adjustable. Different non-woven fabrics require variable dyeing time. The existing technology can only realize the time change by adjusting the speed of the roller. When the non-woven fabrics When the cloth needs to be dyed for a long time, the efficiency is low
