Description

Technical Field

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

[0002] Knitted fabrics are made by knitting yarns into loops and then interlacing them with needles. Currently, knitted fabrics are widely used in clothing fabrics, linings, home textiles and other products.

[0003] Currently, when dyeing knitted fabrics, the knitted fabrics are usually dyed by passing them through a dye vat. However, since the knitted fabrics have many pores, the dye solution cannot penetrate quickly, resulting in low coloring efficiency. Utility Model Content

[0004] In order to solve the above technical deficiencies, the utility model provides a knitted fabric dyeing device, which can enable dye liquid to quickly penetrate the knitted fabric and achieve rapid dyeing.

[0005] The utility model discloses a knitted fabric dyeing device, which comprises a dyeing vat, wherein a first roller and a second roller are rotatably arranged in the middle of the dyeing vat, a first elastic layer is arranged on the outer surface of the first roller, a hemispherical concave structure is evenly arranged on the outer surface of the first elastic layer, the first roller and the second roller are parallel to each other, and the first elastic layer on the first roller is in pressure contact with the second roller, a pair of squeezing roller groups are arranged above the first roller and the second roller, the outer surfaces of the squeezing roller groups are both provided with the second elastic layer, a first spray pipe is arranged between the squeezing roller group and the first roller, a second spray pipe is arranged between the squeezing roller group and the second roller, the first spray pipe and the second spray pipe are connected to a water pump through a pipe, the water pump is connected to the bottom of the dyeing vat through the pipe, a cloth guide roller is arranged above the first roller and above the squeezing roller group, and a power mechanism for driving the cloth guide roller, the first roller, the second roller and the squeezing roller group is arranged outside the dyeing vat.

[0006] When in use, the knitted fabric is passed around the guide roller and the No. 1 roller in turn, and then passed between the No. 1 roller and the No. 2 roller, and then passed upward through the squeezing roller group and discharged from the guide roller. The water pump sprays the dye in the dye vat to both sides of the fabric through the No. 1 spray pipe and the No. 2 spray pipe. The dye accumulates downward along the fabric between the No. 1 roller and the No. 2 roller and flows back to the bottom of the dye vat from both ends between the No. 1 roller and the No. 2 roller. It should be noted here that the height of the dye is lower than the No. 1 roller and the No. 2 roller. Part of the dye will remain in the hemispherical concave structure on the No. 1 elastic layer when the No. 1 roller rotates, so that it can dye the fabric when it comes into contact with the fabric. One side of the fabric is wetted first, and then when the fabric is squeezed between rollers No. 1 and No. 2, the dye on the side of the fabric close to roller No. 1 is further pressed into the fabric for wetting, and the air in the hemispherical concave structure and the air in the fabric are squeezed out. When the fabric leaves rollers No. 1 and No. 2, the hemispherical concave structure recovers its elastic deformation to form a negative pressure. At the same time, the fabric recovers its deformation, and negative pressure is also formed inside the fabric, so that the dye can quickly penetrate the fabric from the unwetted side, achieving rapid dyeing. Finally, the excess dye on the fabric is squeezed out by the squeezing roller group, and the dye further penetrates the fabric while squeezing.

[0007] Furthermore, a mounting plate is provided on the dye vat on the upper side of the No. 2 roller, and an elastic scraper in contact with the No. 2 roller is installed on the mounting plate. The elastic scraper scrapes off the dye on the No. 2 roller, so that the side of the fabric in contact with the No. 2 roller remains dry when entering between the No. 1 roller and the No. 2 roller, thereby facilitating the squeezing out of the air in the fabric.

[0008] The knitted fabric dyeing device obtained by the utility model has the beneficial effects of firstly wetting one side of the fabric by means of the No. 1 elastic layer and the hemispherical concave structure thereon, and then squeezing out the air in the fabric and the air in the hemispherical concave structure by means of the cooperation of the No. 1 roller and the No. 2 roller, so that negative pressure is formed between the fabric and the hemispherical concave structure when they recover their deformation, so that the dye accumulated between the No. 1 roller and the No. 2 roller can quickly enter the fabric, and finally the excess dye on the fabric is squeezed out by the squeezing roller group, and the dye is further penetrated into the fabric during the squeezing.

A No. 1 spray pipe 5 is provided between the squeezing roller group 7 and the No. 1 roller 2, and a No. 2 spray pipe 8 is provided between the squeezing roller group 7 and the No. 2 roller 11. The No. 1 spray pipe 5 and the No. 2 spray pipe 8 are connected to a water pump through a pipe, and the water pump is connected to the bottom of the dye vat 1 through a pipe. A cloth guide roller 4 is provided above the No. 1 roller 2 and above the squeezing roller group 7. A power mechanism for driving the cloth guide roller 4, the No. 1 roller 2, the No. 2 roller 11 and the squeezing roller group 7 is provided outside the dye vat 1.

[0014] When in use, the knitted fabric is passed around the cloth guide roller 4 and the No. 1 roller 2 in sequence, and then passes between the No. 1 roller 2 and the No. 2 roller 11, and then passes upward through the squeezing roller group 7 and is discharged from the cloth guide roller 4. The water pump sprays the dye in the dye vat 1 to both sides of the fabric through the No. 1 spray pipe 5 and the No. 2 spray pipe 8. The dye accumulates downward along the fabric between the No. 1 roller 2 and the No. 2 roller 11 and flows back to the bottom of the dye vat 1 from both ends between the No. 1 roller 2 and the No. 2 roller 11. It should be noted here that the height of the dye is lower than the No. 1 roller 2 and the No. 2 roller 11. Part of the dye will remain in the hemispherical concave structure 12 on the No. 1 elastic layer 3 when the No. 1 roller 2 rotates, thereby When touching, one side of the fabric can be moistened first, and then when the fabric is squeezed between roller No. 1 and roller No. 2, 11, the dye on the side of the fabric close to roller No. 1 is further pressed into the fabric to moisten it, and the air in the hemispherical concave structure 12 and the air in the fabric are squeezed out. When the fabric leaves roller No. 1 and roller No. 2, 11, the hemispherical concave structure 12 restores its elastic deformation to form a negative pressure. At the same time, the fabric restores its deformation, and a negative pressure is also formed inside the fabric, so that the dye can quickly penetrate the fabric from the side that has not been wetted, thereby achieving rapid dyeing. Finally, the excess dye on the fabric is squeezed out by the squeezing roller group 7, and the dye further penetrates the fabric while being squeezed out.
