Description

Technical Field

[0001] The utility model relates to the technical field of gauze manufacturing equipment, and particularly relates to a fabric dyeing device. Background Art

[0002] Natural dyeing uses dyes from natural plants and minerals obtained from nature, without using chemical materials, to dye fibers, threads, and fabrics into various colors, minimizing problems that occur when in contact with the skin, and improving the texture due to its excellent touch. It has been widely used in recent years. Among these natural dyes, various types of dyeing equipment have been developed and used for dyeing natural fibers.

[0003] In the existing fabric dyeing process, generally, the fabric is conveyed forward through a guide roller mechanism. During the process of the fabric being conveyed forward along with the guide rollers, the fabric enters the dyeing pool below for dyeing, and the dyed fabric then enters the subsequent drying device for drying.

[0004] For fabrics dyed with natural dyes, since natural dyes are different from chemical dyes, in the case of natural dyes, the particle size of the dyes is uneven and the natural dyes are pulverized into fine powder and become sludge during the dyeing process. If the process of using guide rollers + dyeing pool for dyeing is adopted, the granular dyes on the surface of the dyed fabric will fall downward during the forward conveying movement, resulting in uneven dyeing.

[0005] In response to this, the existing method for dyeing fabrics with natural dyes is as follows: The dyeing pool is filled with a liquid natural dyeing agent composed of natural dyes (fine - powdered natural dyes + clear water), the fabric to be dyed is immersed in the dyeing pool, and the fabric is turned over in the middle. After reaching the soaking time, it can be taken out. However, for the liquid natural dye that is statically placed in the dyeing pool, after being used for a period of time, the granular natural dyes contained in the liquid natural dye will gradually sink due to their own weight, resulting in uneven distribution of the natural dyeing agent in the dyeing pool up and down, which affects the dyeing effect of the fabric. Summary of the Utility Model

[0006] Aiming at the defects existing in the prior art, the purpose of the present utility model is to provide a fabric dyeing device to solve the problem that when the existing fabrics are dyed with natural dyes, the granular natural dyes sink due to their own weight, resulting in uneven distribution of the natural dyeing agent in the dyeing pool up and down, which affects the dyeing effect of the fabric.

[0007] To achieve the above - mentioned purpose, the technical solution adopted by the present utility model is as follows:

[0008] The present application provides a fabric dyeing device, which includes a container body for containing a dyeing solution, an end cover, a pump body, a dyeing solution supply pipe, a dyeing solution spraying assembly, a pressing plate, and a placement plate. The end cover is detachably and tightly installed on the upper end face of the container body. The dyeing solution supply pipe is vertically arranged in the inner cavity of the container body. The bottom end of the dyeing solution supply pipe is communicated with the liquid outlet of the pump body arranged outside the container body. The placement plate is horizontally installed near the upper part above the bottom end of the inner cavity of the container body. A recovery space is formed between the placement plate and the bottom end face of the container body. The pump body is communicated with the liquid inlet of the pump body through a recovery pipe provided. The pressing plate is horizontally installed near the lower part below the top end of the inner cavity of the container body. The dyeing solution spraying assembly is installed at the top end of the dyeing solution supply pipe. A plurality of spray holes are uniformly arranged along the circumferential direction on the end faces of the pressing plate and the placement plate respectively.

[0009] Further, the dyeing solution spraying assembly includes a spray plate, a top plate, a connecting pipe, and a locking assembly. The top plate is fixedly installed at the top end of the spray plate. A spray space is formed between the top plate and the spray plate. A plurality of liquid outlet holes are uniformly arranged along the circumferential direction on the end face of the top plate. The connecting pipe is arranged at the bottom end of the spray plate. The spray plate is installed at the top end of the dyeing solution supply pipe through the connecting pipe. The spray plate is fixedly installed on the dyeing solution supply pipe through the locking assembly.

[0010] Further, the locking assembly includes a locking bolt. A connecting hole penetrating up and down is formed in the center of the top plate. A fixed pipe arranged axially is provided in the inner cavity of the dyeing solution supply pipe. Internal threads connected to the locking bolt are formed on the inner wall of the top end of the fixed pipe. The locking bolt passes through the connecting hole and is fixedly connected to the internal threads of the fixed pipe.

[0011] Further, the top plate has an outer shape structure with a circular arc cross-section.

[0012] Further, the fabric dyeing device further includes a bracket, and the bracket is fixedly installed at the bottom end of the container body.

[0013] The beneficial effects of the present utility model are as follows: By containing a liquid natural dyeing solution in the inner cavity of the container body, placing the fabric above the placement plate and pressing it tightly with the pressing plate, under the suction action of the pump body, the natural dyeing solution in the inner cavity of the container body is drawn out from the bottom end of the inner cavity of the container body through the recovery pipe, and is conveyed to the dyeing solution spraying assembly through the pump body and the dyeing solution supply pipe and sprayed out in all directions. The sprayed natural dyeing solution is sprayed downward through the spray holes in the pressing plate, so that the natural dyeing solution naturally penetrates into the fabric below, and the remaining dyeing solution after the fabric is dyed falls into the recovery space through the spray holes in the placement plate, and the dyeing solution in the recovery space is conveyed to the dyeing spraying assembly under the action of the pump body, and so on in a cycle, so that the dyeing solution is always in a flowing state during the dyeing process, which can ensure that the granular dyes in the natural dyeing solution are in a uniform state, thereby ensuring the uniformity of the fabric dyeing.

[0026] Continue to refer to the attached Figure 1 to the attached Figure 3 As shown, in this embodiment, the container body 1 adopts a cylindrical outer shape structure. The end cover 2 is detachably and firmly installed at the top of the container body 1 through locking bolts, so that the fabric 200 to be dyed can be put in or the dyed fabric 200 can be taken out. A thermometer or a pressure gauge 12 is installed on the end cover 2, and an observation window can also be formed on the end cover 2 to visually confirm the state during the dyeing process. In addition, in order to keep the container body 1 away from the ground, a bracket 3 is also installed at the bottom end of the container body 1.

[0027] Refer to the attached Figure 2 and the attached Figure 3 As shown, the dyeing liquid supply pipe 9 is vertically installed in the inner cavity of the container body 1. The pump body 5 is arranged on the periphery of the container body 1, such as arranged below the bottom end of the container body 1. The liquid outlet of the pump body 5 is communicated with the bottom end of the dyeing liquid supply pipe 9, and the top end of the dyeing liquid supply pipe 9 is communicated with the dyeing liquid spraying assembly 4.

[0028] Continue to refer to the attached Figure 2 and the attached Figure 3 As shown, the placing plate 8 is horizontally installed adjacent to the upper part of the bottom end of the inner cavity of the container body 1. A recovery space is formed between the bottom end surface of the placing plate 8 and the bottom end surface of the inner cavity of the container body 1, that is, used to collect and store the natural dyeing liquid remaining after the fabric 200 is dyed and falls. The pressing plate 7 is horizontally installed adjacent to the top end of the inner cavity of the container body 1. The function of the pressing plate 7 is to press the fabric 200 to be dyed placed on the placing plate 8, that is, the fabric 200 is pressed and placed on the placing plate 8.

[0029] Refer to the attached Figure 2 and the attached Figure 3As shown, a plurality of spray holes 11 are respectively arranged on the end faces of the placement plate 8 and the pressing plate 7 along the circumferential direction, and through holes penetrating up and down are arranged at the centers of the placement plate 8 and the pressing plate 7 so that the dyeing liquid supply pipe 9 can vertically pass through. The placement plate 8 and the pressing plate 7 can be installed on the dyeing liquid supply pipe 9 by means of threaded connection, that is, internal threads are formed on the inner walls of the through holes of the placement plate 8 and the pressing plate 7, and external threads are formed at corresponding positions on the outer surface of the dyeing liquid supply pipe 9, so that the placement plate 8 and the pressing plate 7 can be detachably and firmly installed on the dyeing liquid supply pipe 9.

[0030] The recovery space is communicated with the liquid inlet of the pump body 5 through the arranged recovery pipe 6, so that the natural dyeing liquid can circulate between the pump body 5, the dyeing liquid supply pipe 9 and the recovery space. In this way, the dyeing liquid is always in a flowing state during the dyeing process, which can ensure that the granular dyes in the natural dyeing liquid are in a uniform state, thereby ensuring the uniformity of the fabric 200 during dyeing.

[0031] Refer to the appendix Figure 2 and the appendix Figure 3 as well as the appendix Figure 5 and the appendix Figure 6 As shown, the dyeing liquid spraying assembly 4 is arranged on the upper part of the dyeing liquid supply pipe 9 so as to spray the supplied natural dyeing liquid onto the fabric 200 placed in the inner cavity of the container body 1 in the form of spraying.

[0032] The dyeing liquid spraying assembly 4 includes a spraying plate 42, a top plate 41, a connecting pipe 43 and a locking assembly. The top plate 41 is arranged above the spraying plate 42, and the top plate 41 and the spraying plate 42 form an outer shape structure similar to a hemisphere or a cap. The connecting pipe 43 is connected below the center of the bottom surface of the spraying plate 42, and the connecting pipe 43 is installed at the upper end of the dyeing liquid supply pipe 9. A plurality of liquid outlet holes 44 are formed on the end face of the spraying plate 42. The liquid outlet holes 44 are formed along the axial direction of the dyeing liquid supply pipe 9, and the liquid outlet holes 44 are arranged in a structure form inclined towards the center direction.

[0033] Refer to the appendix Figure 2 and the appendix Figure 4 as well as the appendix Figure 7 As shown, the spraying plate 42 and the top plate 41 are fixed on the dyeing liquid supply pipe 9 through the locking assembly. The locking assembly includes a locking bolt. A connecting hole 45 penetrating up and down is formed in the center of the top plate 41. A fixing pipe 10 arranged along the axial direction is arranged in the inner cavity of the dyeing liquid supply pipe 9. Internal threads connected to the locking bolt are formed on the inner wall of the top end of the fixing pipe 10. The locking bolt passes through the connecting hole 45 and is fixedly connected to the internal threads of the fixing pipe 10, and the bottom end of the fixing pipe 10 is directly installed on the liquid outlet of the pump body 5 below (refer to the appendix Figure 2As shown). During installation, by sleeving the connecting pipe 43 on the outer end face of the top end of the dyeing solution supply pipe 9, the positioning of the spray plate 42 and the top plate 41 on the dyeing solution supply pipe 9 is achieved. Subsequently, the locking bolt is vertically passed through the connecting hole 45 on the top plate 41, so that the bottom end of the locking bolt extends into the inner cavity of the fixed pipe 10, and by rotating the locking bolt, the locking bolt is threadedly fixed to the inner cavity of the fixed pipe 10. At the same time, the top plate 41 is pressed and installed on the dyeing solution supply pipe 9 by using the locking bolt.

[0034] To better understand the fabric dyeing device in this embodiment, the following briefly describes its working principle:

[0035] Refer to the attached Figure 8 As shown, open the end cover 2, place the fabric 200 to be dyed on the placement plate 8 in the inner cavity of the container body 1, and stack the fabric 200 successively to the top of the dyeing solution supply pipe 9. Subsequently, pour the liquid natural dyeing solution into the inner cavity of the container body 1 (the liquid level of the natural dyeing solution is at least higher than half of the height position of the container body 1). Then, after combining the pressing plate 7 to the dyeing supply pipe, combine the dyeing solution spraying assembly 4 to the top end of the dyeing solution supply pipe 9, and press and fix the top plate 41 on the fixed pipe 10 by means of the locking bolt; Subsequently, the pump body 5 operates to draw the natural dyeing solution at the bottom end (recovery space) of the container body 1 back to the pump body 5 through the recovery pipe 6, and then convey it to the dyeing solution spraying assembly 4 through the dyeing solution supply pipe 9. During this process, the dyeing solution coming out of the dyeing solution supply pipe is reflected to the lower spray plate 42 while hitting the hemispherical top plate 41, and is sprayed downward through the liquid outlet holes 44 formed in the spray plate 42. And because the liquid outlet holes 44 are formed in a longitudinal and inclined form, the natural dyeing solution can be evenly sprayed. In this way, the dyeing solution sprayed on the pressing plate 7 is conveyed to the fabric 200 through the spray holes 11 and finally reaches the placement plate 8. And after the spray holes 11 formed on the placement plate 8 move downward, in the recovery space, the dyeing is carried out again in a circulating manner by the pump body 5. During the whole process, the dyeing solution is always in a flowing state during the dyeing process, so as to ensure that the particulate dyes in the natural dyeing solution are in a uniform state, thereby ensuring the uniformity of the fabric 200 during dyeing.
