Description

Technical Field

[0001] The utility model relates to the field related to the production of textile fabrics, in particular to a dyeing and bleaching device for processing textile fabrics. Background Technique

[0002] Textile fabrics are made by processing fiber raw materials such as cotton, linen, silk, wool, and other synthetic or artificial fibers through a series of processing procedures. Textile fabrics are widely used in various fields of people's lives. Depending on different actual needs, from daily clothing to home decoration, and then to medical, military, industrial and other fields, there are textile fabrics. Due to the different uses of the final products and the desired appearance effects, sometimes it is necessary to dye and bleach textile fabrics through a dyeing and bleaching device to prepare for further processing of the textile fabrics to obtain the required products.

[0003] Chinese Patent: CN214736628U provides a dyeing and bleaching device for processing warp-knitted mesh fabrics. Under the action of the first inlet roller and the first outlet roller, the fabric is conveyed into the dyeing and bleaching box body. After the first stirring box body fully stirs the dye, it is pumped into multiple nozzles in the dyeing and bleaching box body through the first pump body to perform the dyeing and bleaching process on the fabric, which can reduce the input of labor.

[0004] However, when dyeing and bleaching the fabric, the existing patent uses nozzles to spray the fabric with dye on one side. If double-sided dyeing and bleaching of the fabric is required, two dyeing and bleaching operations need to be carried out, which is likely to increase the workload. Moreover, the positions of the nozzles are fixed, and there are gaps between the nozzles, which is likely to cause the dye not to fully cover the fabric, reducing the uniformity of the dye on the textile fabric. At the same time, the sprayed dye is not easy to collect and reuse, and it is easy to cause waste of resources. Summary of the Invention

[0005] Therefore, in order to solve the above deficiencies, the utility model provides a dyeing and bleaching device for processing textile fabrics to solve the above technical problems.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions: A dyeing and bleaching device for processing textile fabrics, including a dyeing and bleaching box, a sewage discharge pipe arranged at the lower right end of the dyeing and bleaching box, and an electromagnetic valve installed on the sewage discharge pipe.

Detailed Description of the Embodiment

[0024] In order to further explain the technical solution of the present utility model, it will be elaborated in detail through specific embodiments below.

[0025] As Figure 1 shown, the present utility model provides a dyeing and bleaching device for processing textile fabrics, including a dyeing and bleaching box 1, a sewage discharge pipe 2 arranged at the lower right end of the dyeing and bleaching box 1, a solenoid valve 14 installed on the sewage discharge pipe 2. An opening for guiding and conveying the textile fabric is formed on each of the left and right sides of the dyeing and bleaching box 1, and a first guide roller 3 is rotatably installed in each opening for guiding and conveying the textile fabric, and the dyeing and bleaching box 1 is internally provided with a dye 4 whose liquid level is lower than the first guide roller 3;

[0026] In this embodiment, the conveying pump 7, the liquid level sensor 13, and the solenoid valve 14 are all connected to an external control device, while the cylinder 126 is connected to an external pneumatic device, which is prior art and will not be elaborated;

[0027] When dyeing and bleaching textile fabrics, the textile fabrics can be sequentially passed through the opening of the dyeing and bleaching tank 1 and then through the top surface of the left first guiding roller 3, the bottom surface of the tensioning roller 5, the top surface of the second guiding roller 10, the top surface of the supporting roller 11, and the right first guiding roller 3, and then connected to an external winding device. The dye 4 is used to dye and bleach the textile fabrics, and the external winding device tightens the textile fabrics, so that the part of the textile fabrics in contact with the tensioning roller 5 is elastically stretched by the extrusion of the tensioning roller 5. At this time, the dye 4 can better pass through the textile fabrics, improving the uniformity of the dyeing and bleaching of the textile fabrics by the dye 4.

[0028] As Figure 1 shown, in this embodiment, it is characterized in that a tensioning roller 5 immersed in the dye 4 is rotatably installed in the dyeing and bleaching tank 1, and a partition frame 6 that divides the dye 4 into two parts is installed at the inner bottom of the dyeing and bleaching tank 1. The partition frame 6 adopts a hollow structure inside, and the height of the partition frame 6 is higher than that of the dye 4. It divides the dye 4 in the dyeing tank 1 into the dye 4 in the use state and the dye 4 in the static state;

[0029] The partition frame 6 is located on the right side of the tensioning roller 5, and a second guiding roller 10 for assisting in guiding the textile fabrics is arranged above the right of the partition frame 6;

[0030] A delivery pump 7 is locked and fixed inside the partition frame 6. A delivery pipe 8 is inserted at each of the input end and the output end of the delivery pump 7. The end of the delivery pipe 8 far from the delivery pump 7 horizontally passes through the inside of the partition frame 6 and then extends into the dye 4 movably to cooperate with the delivery pump 7 to deliver the dye 4. And a filter head 9 is arranged at the end of the delivery pipe 8 far from the delivery pump 7 to filter the dye 4, reducing the continuous flow and use of impurities in the dye 4;

[0031] A supporting roller 11 for providing support for the textile fabrics is arranged on the right side of the second guiding roller 10, and an extrusion mechanism 12 is arranged above the supporting roller 11;

[0032] Among them, an electromagnetic valve 14 is installed on the delivery pipe 8, and the electromagnetic valve 14 on the delivery pipe 8 and the electromagnetic valve 14 on the sewage discharge pipe 2 are separately arranged. After the electromagnetic valve 14 on the delivery pipe 8 is opened, it is convenient for the dye 4 to flow and be delivered in the delivery pipe 8, so as to realize the recycling of the dye 4;

[0033] In this embodiment, the top surfaces of the first guiding roller 3, the second guiding roller 10, and the supporting roller 11 are flush, which is convenient for the textile fabrics to move on the second guiding roller 10 and the supporting roller 11;

[0034] A liquid level sensor 13 for detecting the liquid level height of the dye 4 is installed at each of the left and right ends inside the dyeing and bleaching tank 1. By respectively detecting the heights of the dye 4 on both sides of the partition frame 6 through the two liquid level sensors 13, it is convenient to adjust the dye 4 on both sides of the partition frame 6 subsequently;

[0035] Among them, the height of the conveying pipe 8 is greater than that of the sewage discharge pipe 2, which is convenient for the conveying pipe 8 to convey the dye 4 in the upper layer. Since there are more precipitated impurities in the lower layer of the dye 4, they can be discharged out through the sewage discharge pipe 2;

[0036] One side of the partition frame 6 and the inner side of the dyeing and bleaching tank 1 can accommodate all the dye 4, which is convenient for cleaning the precipitated impurities in the two dyeing tanks 1 after collecting the dye 4 on one side of the partition frame 6;

[0037] Specifically, after the solenoid valve 14 on the conveying pipe 8 is opened and the conveying pump 7 is started, the dye 4 on the right side of the partition frame 6 can be conveyed, so that the dye on the right side of the partition frame 6 is conveyed to the left side for recycling. When it is necessary to clean the precipitated impurities in the dyeing tank 1, the conveying pump 7 can be controlled to cooperate with the conveying pipe 8 to completely introduce the dye 4 on the right side of the partition frame 6 into the left side of the partition frame 6, and the liquid level is detected by two liquid level sensors 13. When it is detected that the dye on the right side of the partition frame 6 is lower than the preset value, the solenoid valve 14 on the sewage discharge pipe 2 can be started, so that the sewage in the dyeing and bleaching tank 1 is discharged out through the sewage discharge pipe 2.

[0038] As Figure 2 shown, in this embodiment, the filter head 9 includes a connecting sleeve 91 and a filter cover 92 arranged on the connecting sleeve 91. The connecting sleeve 91 is fixedly sleeved on the outer end of the conveying pipe 8;

[0039] The filter cover 92 is a hollow hemispherical shape with through holes, and the inner diameter of the filter cover 92 is greater than the outer diameter of the conveying pipe 8, so that the filter cover 92 can comprehensively filter the dye 4 entering the conveying pipe 8;

[0040] During use, the dye 4 entering the conveying pipe 8 is filtered by the filter cover 92, reducing the secondary pollution of the textile fabric caused by the impurities in the dye 4 during the recycling of the dye 4.

[0041] As Figure 3 shown, in this embodiment, the extrusion mechanism 12 includes an extrusion roller 121 arranged above the support roller 11. The front and rear ends of the extrusion roller 121 are each rotatably installed with a sliding block 122 through a rotating shaft. The top surface of each sliding block 122 is installed with a connecting rod 123, and the sliding block 122 is slidably connected to the inner side of the dyeing and bleaching tank 1, and the sliding block 122 can vertically move up and down along the inner side of the dyeing and bleaching tank 1;

[0042] A spring 124 is movably sleeved outside the connecting rod 123, and the connecting rod 123 movably extends into the inner side of the sleeve 125. The two ends of the spring 124 are respectively connected to the top surface of the sliding block 122 and the bottom end surface of the sleeve 125. The sleeve 125 is connected to the bottom piston rod of the cylinder 126, and the cylinder 126 is locked and fixed on the support frame 127. The support frame 127 is horizontally installed in the upper middle part of the inner side of the dyeing and bleaching tank 1;

[0043] During use, the cylinder 126 can be controlled to drive the sleeve 125, the spring 124, the connecting rod 123, the sliding block 122 and the squeezing roller 121 to move downward. The downward movement of the squeezing roller 121 cooperates with the supporting roller 11 to squeeze the dyed textile fabric, so as to squeeze the excess dye 4 in the textile fabric into the space on the right side of the partition frame 6. The setting of the spring 124 can prevent the squeezing roller 121 from applying too much pressure to the textile fabric, resulting in the inability of the textile fabric to move. After the squeezing roller 121 applies a certain pressure to the textile fabric, the connecting rod 123 moves upward under the pressure and the spring 124 is compressed, so that the textile fabric can pass through between the squeezing roller 121 and the supporting roller 121 more stably. The dye 4 enters the right side of the partition frame 6 for standing, and the impurities squeezed off from the textile fabric settle by standing, which is convenient for subsequent discharge through the sewage pipe 2 to reduce the impurities in the dye 4 and improve the dyeing quality of the textile fabric.

[0044] The above are only the preferred examples of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
