Description

Technical Field

[0001] This utility model relates to the field of fabric dyeing technology, and specifically to a fabric dyeing apparatus. Background Technology

[0002] Textile fabrics refer to various fiber materials made through textile processes. They are the basic materials used to make clothing, home furnishings, industrial products, and other textiles. There are many types of textile fabrics, including fabrics made from different raw materials such as cotton, linen, silk, wool, and chemical fibers, each with different properties and uses.

[0003] Patent CN212771393U discloses a rapid dyeing device for fabric processing, including a dyeing tank body. The dyeing tank body has an inlet on one side and an outlet on the other side. An assembly of fabric rollers is installed inside the dyeing tank body, and a dyeing pool is located at the bottom of the body. A movable door is located at the front of the dyeing tank body. This invention allows observation of the internal workings of the dyeing tank body through a glass window. The movable door can be rotated open, allowing for timely and convenient adjustments if errors occur during the dyeing process. It also facilitates the repair and cleaning of internal parts. The movable door can be easily opened and closed via a pin rod, pin hole, and pin lock. The fabric rollers guide the fabric from the inlet to the dyeing pool and then to the outlet. When the dye in the dyeing pool is insufficient, dye can be added directly through the water inlet.

[0004] The above-mentioned rapid dyeing device has the following problems: Before dyeing, the fabric will have residual fiber lint, thread ends and dust and other impurities. If the impurities are not cleaned, they will combine with the dye during the dyeing process to form color spots and defects, resulting in an increased defect rate of the fabric.

[0023] The following is a description of the embodiments and appendices. Figures 1-2 The technical solution of this utility model will be further described below.

[0024] Example 1

[0025] A fabric dyeing apparatus, comprising:

[0026] The pretreatment chamber 1 includes a guide roller group 11, a brush roller group 12, a blower 13, and a mesh 14. The brush roller group 12 is disposed between the guide roller groups 11 and its brush assembly can abut against the fabric surface. The blower 13 is disposed at one end of the pretreatment chamber 1 near the outlet, and the mesh 14 is disposed at one end of the pretreatment chamber 1 near the inlet.

[0027] The dyeing chamber 2 includes a guide roller assembly 21 and stirring blades 22.

[0028] The drying chamber 3 includes a guide roller assembly 31, a fan 32 disposed at the upper end of the guide roller assembly 31, and a drying mechanism 33 disposed at the lower end of the guide roller assembly 31.

[0029] like Figures 1-2As shown, the workflow of this utility model is as follows:

[0030] First, the fabric enters from the inlet of the pretreatment chamber 1 and moves forward smoothly under the guidance of the guide roller group 11. During the fabric's movement, the brush roller group 12 operates synchronously up and down to thoroughly clean both sides of the fabric surface, brushing off fiber lint and fine dust. At the same time, the blowers 13 on both sides of the brush roller group 12 are started, and the airflow generated blows the cleaned impurities onto the adhesive net 14 located at the inlet. The impurities are firmly adsorbed and collected by the adhesive net 14. The pretreated fabric continues to enter the dyeing chamber 2 under the guidance of the guide roller group 11.

[0031] Secondly, the fabric is guided by the second set of guide rollers 21, first passing around the first set of rollers above, and then immersed in the dye bath, where it is fully dyed in the circulating dye bath driven by the stirring blades 22.

[0032] Finally, the dyed fabric enters the drying chamber 3 and moves along the arc-shaped path of the guide roller group 31. The infrared heating tube below radiates heat to heat the fabric, while the fan 32 above blows airflow to accelerate moisture evaporation. Finally, it is sent out from the outlet of the drying chamber 3, completing the entire dyeing process.

[0033] The brush roller assembly 12 of this invention operates synchronously from top to bottom, thoroughly cleaning the fibers and fine dust on both sides of the fabric. Combined with the blower 13 blowing in a specific direction, it concentrates the impurities and sends them to the adhesive net 14 at the inlet, forming a "cleaning-collection" closed loop. This effectively avoids the impact of impurity residue on the dyeing quality and reduces problems such as color spots and defects. The stirring blades 22 drive the dye liquor circulation, preventing sedimentation and stratification, ensuring uniform dye liquor concentration, making the fabric dyed consistently, and improving the quality stability of the dyed finished product.

[0034] As a further preferred embodiment, an extrusion mechanism 4 is provided on the side of the dyeing chamber 2 near the drying chamber 3. The extrusion mechanism 4 includes an extrusion seat 41, a lower extrusion roller 42, a guide slide column 43, a top cover 44, a sliding seat 45, an upper extrusion roller 46, and an adjusting stud 47. The extrusion seat 41 is disposed in the drying chamber 3. The lower extrusion roller 42 is rotatably disposed on the extrusion seat 41. The guide slide column 43 is disposed on the upper end of the extrusion seat 41 and the top cover 44 is fixedly disposed on its top end. The sliding seat 45 is slidably disposed on the guide slide column 43. The upper extrusion roller 46 is rotatably disposed on the sliding seat 45. The threaded portion of the adjusting stud 47 is threadedly connected to the top cover 44 and its lower end is rotatably disposed in the rotating seat at the upper end of the sliding seat 45.

[0035] Specifically, first, depending on the fabric material (such as cotton, chemical fiber) and thickness, rotate the handwheel of the adjusting stud 47. The specific adjustment process is as follows: When rotated clockwise, the stud moves downward, pushing the sliding seat 45 down along the guide slide 43, and the upper extrusion roller 46 moves closer to the lower extrusion roller 42, reducing the distance between the two rollers and increasing the extrusion pressure; when rotated counterclockwise, the stud retracts upward, and the sliding seat 45 rises under the action of gravity, increasing the distance between the two rollers and decreasing the extrusion pressure.

[0036] Secondly, the dyed fabric is sent out from the guide roller group 21 of the dyeing chamber 2 and enters the space between the upper and lower extrusion rollers of the extrusion mechanism 4. During the extrusion process, the fabric moves forward under the clamping of the two rollers, and the excess dye liquid on the surface is squeezed out, so as to avoid the drying time being prolonged due to excessive moisture after entering the drying chamber 3.

[0037] As a further preferred embodiment, a guide plate 51 is provided at the lower end of the extrusion seat 41. The guide plate 51 is inclined toward the dyeing chamber of the dyeing chamber 2. A baffle 52 is provided on the side of the guide plate 51 facing the dyeing chamber. A filter screen 521 is provided on the baffle 52. The filter screen 521 is located on the upper side of the guide plate 51.

[0038] Specifically, the fabric moves forward under the clamping of two rollers, and excess dye liquor on the surface is squeezed out and drips down the roller surface onto the guide plate 51 below. Under the tilting action of the guide plate 51, the dye liquor flows towards the dyeing chamber. When passing through the filter screen 521, impurities such as fabric fibers and lint mixed in are intercepted by the filter screen. The filtered clean dye liquor flows back to the dyeing tank of the dyeing chamber 2 through the filter screen, realizing recycling.

[0039] As a further preferred embodiment, the stirring blades 22 are provided in multiple sets.

[0040] Specifically, the three-dimensional stirring mode of multiple sets of blades covers the entire area of ​​the dye bath, effectively solving the problem of blind spots in the traditional single-blade stirring, avoiding local dye precipitation or excessive concentration, making the fabric more evenly colored and significantly reducing color difference.

[0041] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
