Description

A fabric dyeing and pre-drying device

Technical field:

The utility model relates to the technical field of fabric dyeing equipment, in particular to a fabric dyeing and pre-drying device.

Background technique:

Pad dyeing is a commonly used dyeing technique. The machine used is generally a continuous pad dyeing machine, which is usually used for large-scale dyeing processing of woven fabrics, and has high labor productivity. The dyeing process of pad dyeing is: pad dyeing solution, pre-drying, drying, color fixing, washing, soaping, drying.

The commonly used continuous pad dyeing machine divides the pad dyeing solution and pre-drying into two independent units. The webbing after padding cannot be pre-dried directly, the dyeing solution is prone to swimming, and the uneven distribution of dyes leads to color difference.

Drying fabrics with infrared rays is a commonly used method for pre-drying, which can heat the surface and interior of the fabric at the same time, but the commonly used infrared drying method has uneven radiation on the front and back sides of the fabric, which is prone to color difference between the front and back sides. In addition, due to the short time of dip-dyeing, the fabric travels fast, and it is difficult for the fabric to be fully dried in the heating chamber, and it is also prone to migration and color difference.

Utility model content:

The purpose of the utility model is to provide a fabric dyeing and pre-drying device aiming at the deficiencies of the prior art, which has a scientific and simple structure and can effectively prevent and reduce color difference during the fabric dyeing process.

In order to achieve the above object, the utility model adopts the following technical scheme, which includes a support, a dyeing tank, a dyeing tank roller, a roller device, and a heating chamber. The dyeing tank roller is installed in the dyeing tank, and there is a heating chamber above the dyeing tank. There is a roller device between the chamber and the dyeing tank. In the heating chamber, there are infrared emitters, belt threading guide shafts, and guide shafts. The belt threading guide shafts are arranged horizontally. There are one row above and below the heating chamber. The ribbon travel channel in the direction, this channel is also a heating channel, the infrared emitters are evenly arranged in the heating chamber, aligned with the axis of the belt threading guide shaft in the vertical direction, so that the infrared emitters are symmetrically distributed on both sides of the heating channel .

There is at least one roller in the dyeing tank.

There is a tension detection device on the roller device to detect the tension of the webbing.

The roller device includes rollers, rollers with adjustable gaps, and air cylinders. The rollers with adjustable gaps are connected to the cylinders, and the gaps between the rollers can be adjusted through the cylinders to obtain the required rejection rate.

The bottom of the heating chamber has a material inlet and a material outlet, and the distance between the material inlet and the material outlet is relatively close to reduce heat dissipation and keep the temperature in the heating chamber relatively constant.

The beneficial effects of the utility model are as follows: a roller device is installed between the heating chamber and the dyeing tank, and the gap between the rollers can be adjusted through the air cylinder to obtain the required excess rate; The guide shaft forms at least one heating channel in the heating chamber. The heating channel is in a vertical direction. The infrared emitters are symmetrically distributed on both sides of the heating channel to reduce the migration of the dye solution on the webbing before and during the infrared drying. Make the fabric fully and evenly dry, prevent and reduce the color difference in the fabric dyeing process.

Description of drawings:

Fig. 1 is a schematic structural view of an embodiment of the utility model.

Detailed ways:

As shown in Figure 1: the utility model includes a support 1, a dyeing tank 2, a dyeing tank roller 3, a roller device 4, and a heating chamber 5. A dyeing tank roller 3 is installed in the dyeing tank 2, and a heating chamber is arranged above the dyeing tank 2 5. A roller device 4 is arranged between the heating chamber 5 and the dyeing tank 2. In the heating chamber 5, there are infrared emitters 51, belt threading guide shafts 52, and guide shafts 53. The belt threading guide shafts 52 are arranged horizontally. There is a row up and down respectively, and the threading guide shaft 52 forms a plurality of vertical webbing passages. This passage is also a heating channel. The axes are aligned so that the infrared emitters 51 are symmetrically distributed on both sides of the heating channel. There are two dyeing tank rollers 3 and a tension detection device 44 on the roller device 4 to detect the tension of the webbing and judge the tightness of the webbing. Excessive tension causes webbing 6 to break, and roll device 4 contains roll 41, roll 42 with adjustable gap, and cylinder 43. Roll 42 is connected with cylinder 43, and roll 41 is connected with motor (not shown in the figure). The fabric 6 advances, and the bottom of the heating chamber 5 has a feed inlet 54 and a discharge outlet 55, which reduces heat dissipation and makes the temperature in the heating chamber 5 relatively constant.

Embodiment has two dyeing tank rollers, three rollers, and padding is two dipping and two rollings, and also embodiment is one dipping one rolling, one dipping two rollings or many dipping one rollings etc.

An example is as follows when used: 4 webbings 6 are side by side, enter the dyeing tank 2 from the left side under the traction of the roller 41 to dip in the dyeing solution, the dipping time is 4s, squeezed by the roller device 4, the dyeing solution penetrates into the fabric 6 and removes the remaining The remaining liquid flows back into the dye tank 2 along the fabric 1, the fabric 6 enters the heating chamber 5 along the feed port 54, and 10 threading guide shafts 52 form 11 heating channels in the heating chamber 5, and the heating channels are vertical , infrared emitters 51 are symmetrically distributed on both sides of the heating channel, and the webbing 6 is evenly dried, then the webbing changes direction along the guide shaft, and leaves the heating chamber 5 through the discharge port 55, and the time for the webbing 6 to pass through the heating chamber is 100s. The temperature is 120°C, and the fabric 6 quickly enters the heating chamber 5 after pad dyeing, so as to reduce the migration of the dye solution on the webbing before and during the infrared drying, so that the fabric is fully and evenly dried, and prevents and reduces the dyeing process of the fabric. Chromatic aberration occurs.

The above is only a preferred embodiment of the utility model, so all equivalent changes or modifications made according to the structure, features and principles described in the utility model patent application scope are all included in the utility model patent application scope .
