Description

Technical Field

[0001] The utility model relates to the field of printing and dyeing machines, in particular to a uniform dyeing mechanism of a printing and dyeing machine. Background Art

[0002] At present, printing and dyeing is a processing method, which is also a general term for pre-treatment, dyeing, printing, finishing, washing, etc. With the rapid development of science and technology, the printing and dyeing technology of textiles in my country has also been improved, and has changed from ancient manual printing and dyeing to modern mechanical printing and dyeing, and the process flow is singeing, dyeing, and drying.

[0003] In the prior art, such as a cloth dyeing and drying machine disclosed in announcement number CN 210104259 U on February 21, 2020, the dyeing mechanism simply presses the singed cloth into the dye, and then directly enters the squeezing and drying process. The hair residue still adheres to the cloth, resulting in the defect of uneven cloth dyeing. Utility Model Content

[0004] In order to overcome the shortcomings of the background technology, the utility model provides a uniform dyeing mechanism for a printing and dyeing machine with good dyeing effect.

[0005] The technical solution adopted by the utility model: a uniform dyeing mechanism of a printing and dyeing machine, which includes a first dyeing tank and a second dyeing tank, wherein the first dyeing tank and the second dyeing tank are both provided with a plurality of pressing rollers for pressing the cloth into the dye, and the first dyeing tank is provided with a brush roller at positions corresponding to the upper and lower sides of the cloth, and the second dyeing tank is also provided with a water squeezing component, wherein the water squeezing component includes a rotatably mounted first water squeezing roller, a second water squeezing roller and a fixedly mounted blowing roller, and the first water squeezing roller and the second water squeezing roller are both provided with an elastic rubber sleeve.

[0006] A soft brush is installed on the brush roller, and the rotation direction of the brush roller is opposite to the advancing direction of the cloth.

[0007] The first squeeze roller and the second squeeze roller are provided with a plurality of grooves on their circumferential surfaces, and the inner wall of the elastic rubber sleeve is provided with convex ribs embedded in the grooves.

[0008] The circumferential surface of the blowing roller is smoothly arranged and is provided with a notch arranged along the length direction. A high-pressure air duct communicating with high-pressure gas is penetrated at the center position of the blowing roller.

[0009] The surface of the high-pressure air duct is provided with air outlets arranged linearly.

[0010] Both sides of the notch are rounded.

[0011] The second squeezing roller is located in the middle and is higher than the first squeezing roller and the blowing roller on both sides, and the notch of the blowing roller is facing the first squeezing roller.

[0012] The beneficial effect of the utility model is as follows: the technical scheme divides the dyeing pool into two, primary dyeing is carried out in the first dyeing pool, and hair residues on the cloth are removed by a brush roller, and then the cloth enters the second dyeing pool for secondary dyeing, and after dyeing is completed, the cloth is squeezed by the first squeezing roller and the second squeezing roller, and the dye falls back into the second dye pool, and the cloth is finally preliminarily dried by the high-pressure air of the blowing roller, which has the advantages of uniform dyeing and high pass rate. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 1 It is a structural schematic diagram of the uniform dyeing mechanism of the printing and dyeing machine according to an embodiment of the utility model.

[0014] Figure 2 for Figure 1 A partial enlarged view of point A in the middle. DETAILED DESCRIPTION

[0015] The following is a further description of the embodiments of the present invention in conjunction with the accompanying drawings:

[0016] As shown in the figure, the uniform dyeing mechanism of the printing and dyeing machine includes a first dyeing tank 1 and a second dyeing tank 2. The first dyeing tank 1 and the second dyeing tank 2 are both provided with a plurality of pressing rollers 3 for pressing the cloth into the dye. The first dyeing tank 1 is provided with a brush roller 4 at the positions corresponding to the upper and lower sides of the cloth. The second dyeing tank 2 is also provided with a water squeezing component, and the water squeezing component includes a rotatably mounted first water squeezing roller 5, a second water squeezing roller 6 and a fixedly mounted blowing roller 7. The first water squeezing roller 5 and the second water squeezing roller 6 are both sleeved with an elastic rubber sleeve 8. The technical solution divides the dyeing tank into two, and primary dyeing is carried out in the first dyeing tank, and the hair residue on the cloth is removed by the brush roller, and then the cloth enters the second dyeing tank for secondary dyeing. After the dyeing is completed, the cloth is squeezed by the first water squeezing roller and the second water squeezing roller, and the dye falls into the second dye tank again. The cloth is finally preliminarily dried by the high-pressure air of the blowing roller, which has the advantages of uniform dyeing and high qualified rate.

[0017] Among them, the first squeezing roller 5 and the second squeezing roller 6 are rotatably installed on the side wall of the second dyeing tank, and there is soft contact between the two. The cloth will be squeezed dry when passing between the two. The circumferential surfaces of the second squeezing roller and the blowing roller are also in contact with each other, which can also play a role in squeezing out water.

[0018] In addition, the second squeezing roller is located in the middle and higher than the first squeezing roller and the blowing roller on both sides. The notch of the blowing roller faces the first squeezing roller. The moisture blown away by the high-pressure gas on the cloth can be blocked by the first squeezing roller and fall into the second dyeing tank below.

[0019] A soft brush 9 is installed on the brush roller 4, and the rotation direction of the brush roller 4 is opposite to the forward direction of the cloth. The brush roller in this embodiment is driven by a motor to rotate, and the soft brush can take away the hair residue adhering to the cloth during rotation.

[0020] The first squeezing roller 5 and the second squeezing roller 6 are provided with a plurality of grooves 10 on their circumferential surfaces, and the inner wall of the elastic rubber sleeve 8 is provided with convex ribs 11 embedded in the grooves 10. The elastic rubber sleeve can be deformed by force when squeezing the cloth, has a good squeezing effect, and can protect the cloth. In addition, the cooperation between the grooves and the convex ribs can ensure that the elastic rubber sleeve does not slip, and has the advantage of good working stability.

[0021] The circumferential surface of the blowing roller 7 is smooth and has a notch 12 arranged along the length direction. A high-pressure air duct 13 connected to the high-pressure gas is passed through the center position of the blowing roller 7. The blowing roller is fixedly installed on the side wall of the second dyeing tank, and the circumferential surface is smooth, which can reduce the friction on the cloth.

[0022] The surface of the high-pressure air duct 13 is provided with linearly arranged air outlets 14, and the air outlets are directly facing the cloth at the notch. High-pressure air is blown out from the air outlets to blow away the moisture on the cloth, which plays a role in preliminary drying. After that, the cloth will enter the drying mechanism for thorough drying.

[0023] The two sides of the notch 12 are rounded to prevent the fabric from being damaged.

[0024] In the description of the present invention, it should be noted that the terms "center", "longitudinal", "lateral", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.
