Description

Technical Field

[0001] The utility model belongs to the technical field of textile processing, and particularly relates to an impregnation device for improving the utilization rate of a flame retardant. Background Art

[0002] The original meaning of textile is the general term for spinning and weaving. Nowadays, textile is not only the traditional hand-spinning and weaving, but also includes non-woven technology, modern three-dimensional weaving technology, modern electrostatic nano-netting technology and other production of clothing, industrial and decorative textiles. Therefore, modern textile refers to a multi-scale structural processing technology of fiber or fiber assembly. In the processing of various special fabrics, such as the fabrics of fire-fighting suits, good flame retardant effect is required, which inevitably requires adding flame retardants to the fabrics during the processing, usually by impregnation, but there are still the following disadvantages in the actual impregnation process:

[0003] First, before the fabric is impregnated, there may be thread ends or floating dust on its surface. If it is directly impregnated, these thread ends and floating dust will enter the impregnation equipment and affect the impregnation effect.

[0004] Secondly, in conventional impregnation treatment, most of them are directly piled into the equipment for impregnation treatment. A large number of fabrics are piled together. Firstly, wrinkles are easily generated. Secondly, the fabrics are easily in contact with each other and cannot be fully exposed to the flame retardant.

[0005] Finally, the impregnation treatment only by immersion takes a long time, so it is faster and more efficient to carry out the impregnation treatment so that the flame retardant can enter the interior of the fabric more quickly. Utility Model Content

[0034] The scraper 202 is symmetrically distributed with the scraping teeth 2021. When the fabric 6 passes through, the upper and lower surfaces of the fabric 6 first contact the scraping teeth 2021, and then contact the side edge of the scraper 202 close to scrape off the thread ends on the surface of the fabric 6. Then the fabric 6 passes between the two brush rollers 203.

[0036] The fabric 6 passing through the guide roller 301 is first surrounded and redirected by the two redirecting rollers 405 at the bottom layer, and then wound and redirected on the two redirecting rollers 405 above it, until the fabric 6 is wound and redirected around all the redirecting rollers 405 to achieve reciprocating winding, and then placed in the impregnation box 1 for impregnation treatment. During this process, the fabric 6 always remains flat, and there is enough spacing between the multiple layers of redirected fabric 6, which is sufficient to fully contact the flame retardant and other substances in the impregnation box 1;

[0049] The nozzle 5 is located below the rollers 404 and above the redirecting rollers 405 , and in a top view, a nozzle 5 is disposed between each of two adjacent groups of rollers 404 .

[0050] The specific working principle of the utility model is as follows: first, before the fabric 6 is impregnated, it is first scraped by the scraper 202 and the scraping teeth 2021 on its side to scrape off the sticking thread ends and other debris, then the motor 204 drives a brush roller 203 to rotate, and the other brush roller 203 also rotates under the meshing transmission of two gears 2031, and the two rotate in opposite directions. At this time, the bristles 2032 on the brush roller 203 contact the upper and lower surfaces of the fabric 6 to sweep away the floating dust on its surface, first drive the ear plate 401 to rise by the cylinder 102, so that the top plate 4 rises, and the redirecting roller 405 rises to a certain height, which is convenient for winding and impregnation treatment on its surface, and the fabric 6 passing through the guide roller 301 is first surrounded and redirected by the two redirecting rollers 405 at the bottom layer, and then The fabric 6 is wound around the two redirecting rollers 405 above it and redirected until it is wound around all the redirecting rollers 405 to achieve reciprocating winding. Then the cylinder 102 works to place the redirecting rollers 405 inside the impregnation box 1. Then the fabric 6 is introduced between the rollers 404. After being rolled by a group of rollers 404, the excess flame retardant inside the fabric 6 is squeezed out and then immersed in the flame retardant in the impregnation box 1. At the same time, the water pump 103 extracts the flame retardant in the impregnation box 1, inputs it into the main pipe 502, and then inputs it into the nozzle 5, and sprays it out through the nozzle 501, so that the flame retardant is quickly stirred and quickly contacts the rolled fabric 6 in large quantities.
