Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of printing and dyeing equipment, and particularly relates to a pretreatment device for high-wettability polyester fabrics. Background Art
[0002] In order to improve the strength of fabrics, sizing treatment is usually carried out on yarns before weaving. The existence of these sizing agents affects the dyeing performance and hand feeling of the fabrics. Therefore, before dyeing, it is necessary to remove the sizing agents from the fabrics with a hot alkali solution. When the fabrics remove the sizing agents, a large amount of hot alkali solution will be carried out. The hot alkali solution has a high alkali content and a high pH value. The outflow of the hot alkali solution will cause serious environmental impacts. At the same time, the consumption of the hot alkali solution is large, and the corresponding production cost is relatively high. Summary of the Invention
[0003] The utility model mainly solves the technical problems existing in the above-mentioned prior art, and provides a pretreatment device for high-wettability polyester fabrics.
[0004] The above technical problems of the utility model are mainly solved by the following technical solutions: A pretreatment device for high-wettability polyester fabrics includes two side plates. A liquid storage tank is arranged between the two side plates. A squeezing roller is arranged between the two side plates in the liquid storage tank. The two squeezing rollers are longitudinally aligned. Above the left and right sides of the upper squeezing roller, a squeezing guide roller is symmetrically arranged on each side. Both ends of the squeezing roller and the squeezing guide roller are rotatably connected to the side plates. The top of the liquid storage tank is provided with a fabric feeding roller group and a winding roller group. Both the fabric feeding roller group and the winding roller group include two support plates arranged on the side plates. Two fabric feeding guide rollers are arranged between the two support plates in the fabric feeding roller group. Both ends of the fabric feeding guide rollers are rotatably connected to the support plates. An inclined groove is arranged on the two support plates in the fabric feeding roller group. The side of the inclined groove close to the winding roller group is higher than the other side. A gravity roller is arranged between the two inclined grooves. A fabric receiving roller is arranged between the two support plates of the winding roller group.
[0005] Preferably, a liquid receiving guide plate is arranged on one side of the liquid storage tank close to the fabric feeding roller group.
[0006] Preferably, a drain pipe is connected to the liquid storage tank.
[0007] The utility model has the beneficial effects that: By arranging two squeezing guide rollers in the liquid storage tank, the hot alkali solution in the fabric can be effectively squeezed out by the two squeezing guide rollers and collected and recycled in the liquid storage tank, so as to avoid the leakage of the hot alkali solution and affect the environment; By arranging the fabric feeding roller group, the hot alkali solution on the fabric can be preliminarily filtered out by the fabric feeding roller group, and the amount of the hot alkali solution on the fabric can be reduced in advance, so that the squeezing roller can more effectively remove the hot alkali solution in the fabric.

Specific embodiments
[0010] The technical solution of the present utility model will be further specifically described below through embodiments in conjunction with the accompanying drawings.
[0011] Embodiment: A pre-treatment device for high wettability polyester fabric, as Figure 1 shown, includes two side plates 1. A liquid storage tank 2 is provided between the two side plates 1. A squeezing roller 3 is mounted between the two side plates 1 in the liquid storage tank 2. The two squeezing rollers 3 are longitudinally aligned. Above the left and right sides of the upper squeezing roller 3, a squeezing and guiding cloth roller 4 is symmetrically mounted on each side. The two ends of the squeezing roller 3 and the squeezing and guiding cloth roller 4 are rotatably connected to the side plate 1. At the top of the liquid storage tank 2, a feeding roller group and a winding roller group are provided. Both the feeding roller group and the winding roller group include two support plates 5 provided on the side plate 1. Two feeding and guiding cloth rollers 6 are mounted between the two support plates 5 in the feeding roller group. The two ends of the feeding and guiding cloth roller 6 are rotatably connected to the support plate 5. An inclined groove 7 is provided on the two support plates 5 in the feeding roller group. The side of the inclined groove 7 close to the winding roller group is higher than the other side, and a gravity roller 8 is mounted between the two inclined grooves 7. A cloth receiving roller 9 is mounted between the two support plates 5 of the winding roller group.

[0013] Principle of the present utility model: During use, first, the fabric is passed through the upper feeding and guiding cloth roller 6 in the feeding roller group, passed between the two feeding and guiding cloth rollers 6, bypassed the lower feeding and guiding cloth roller and then wound to the inner side of the squeezing and guiding cloth roller 4 on the same side, and then passed out between the two squeezing rollers 3, bypassed the squeezing and guiding cloth roller 4 on the right side and then wound on the cloth receiving roller 9. During this period, the gravity roller 8 abuts against the inner side of the fabric. The fabric is first preliminarily removed through the feeding roller group and the gravity roller 8, and the hot alkali solution in the fabric is completely removed through the squeezing roller 3.
