Description

Technical Field

[0001] The utility model relates to the field of fabric printing and dyeing production equipment, in particular to a water washing device for printing and dyeing fabrics. Background Art

[0002] In the process of fabric printing and dyeing, a water washing device is used to wash out some dyes and chemical agents that are not firmly attached to the surface of the fabric belt, and the excess water contained in the fabric after water washing is drained through a squeezing roller. For example, the Chinese utility model patent CN207376264U discloses a printing and dyeing water washing device, which includes a water tank and a frame. A guiding device for guiding the movement of the fabric and immersing it in the water tank and a squeezing device for squeezing out the water in the fabric are arranged on the frame. The guiding device includes a plurality of guiding rollers, and the fabric is wound around the guiding rollers. The squeezing device includes two squeezing rollers, and the fabric passes through between the two squeezing rollers, and the two squeezing rollers squeeze the fabric to squeeze out the water in the fabric. However, in the above technology, the fabric only undergoes one water wash and one squeeze in one water tank, and the utilization rate of the water tank is relatively low. When there are more dyes and chemical agents that are not firmly attached to the fabric surface, multiple sets of water washing devices need to be set up to ensure thorough cleaning, which will increase costs and usage space.

[0003] Therefore, the applicant applied for the Chinese utility model patent CN211339988U, which discloses a fabric water washing device. There are 3 squeezing rollers arranged above each water washing partition tank, namely a water washing driving roller, an upper water washing driven roller and a lower water washing driven roller. In one water washing partition tank, the fabric undergoes two water washes and two squeezes, increasing the utilization rate of each water washing partition tank and improving the cleaning effect of the fabric, and can reduce the number of water washing partition tanks to a certain extent. However, in this technology, the fabric can only be cleaned by the water in the water washing partition tank, and the water in the water washing partition tank contains dyes and chemical agents washed out from the fabric, which will also affect the cleaning effect of the fabric to a certain extent.

[0004] Therefore, it is necessary to provide a technical solution to solve the above problems. Summary of the Utility Model

Detailed implementation manner

[0027] For the convenience of understanding by those skilled in the art, the following combines embodiments with the drawings to further illustrate the present utility model. The content mentioned in the implementation manner does not limit the present utility model.

[0028] The present utility model provides a water washing device for printing and dyeing fabrics, mainly used for water washing of printed and dyed webbing; as Figures 1 to 5 shown, it includes a plurality of water washing units 100 arranged in sequence from left to right. The leftmost side of the water washing device is the fabric feeding end, and the rightmost side is the fabric discharging end. Each water washing unit 100 includes a tank body 1. A support box body 2 is arranged at the upper end of the tank body 1, and an extrusion cleaning mechanism 3 is arranged at the upper end of the support box body 2; the extrusion cleaning mechanism 3 includes a water receiving tank 31 arranged at the upper end of the support box body 2, support frames 32 arranged on the front and rear sides at the upper end of the water receiving tank 31. A plurality of pressing rollers 33 are arranged in sequence from top to bottom between the two support frames 32. Spray pipes 34 are respectively arranged at the inlet ends between adjacent pressing rollers 33. The spray pipes 34 are arranged parallel to the pressing rollers 33, and a plurality of water spraying holes are arranged on the spray pipes 34. The two ends of the spray pipes 34 are respectively arranged in the two support frames 32; a water outlet is arranged at the bottom of the water receiving tank 31, and the water outlet is connected to a water outlet pipe assembly 35. Through holes for the fabric to pass through are arranged on the left and right side walls of the water receiving tank 31 and on the left and right sides outside the water receiving tank 31. Preferably, there are three pressing rollers 33, which are the upper roller 331, the middle roller 332, and the lower roller 333 in sequence from top to bottom. Spray pipes 34 are respectively arranged at the inlet ends between the upper roller 331 and the middle roller 332, and between the middle roller 332 and the lower roller 333.

[0029] In actual use, two water washing units 100 are combined together to form an independent water washing device. The number of water washing devices is selected according to the needs of the actual production process. For example, when there are 2 water washing devices, there are a total of 4 water washing units 100, as Figure 3As shown, adjacent water washing devices are closely arranged. The fabric enters between the upper roller 331 and the middle roller 332 from the left feeding end. Since a spray pipe 34 is arranged at the inlet end between the upper roller 331 and the middle roller 332, the spray pipe 34 first sprays clear water on the fabric. Part of the clear water is adsorbed by the fabric, and the rest flows out after passing through the fabric. The flowing-out part can take away some impurities on the fabric surface (mainly dyes and chemical agents that are not firmly attached). Then the fabric enters between the upper roller 331 and the middle roller 332. The upper roller 331 and the middle roller 332 squeeze out the water adsorbed on the fabric. The squeezed-out water can also take away some impurities on the fabric surface, so that the fabric is first cleaned by the spray pipe 34 before entering the tank 1, reducing the pollution to the tank 1. And the water in the spray pipe 34 forms sewage after cleaning the fabric belt, and the sewage directly flows into the water receiving tank 31 and is discharged outwards through the water outlet pipe assembly 35, thus preventing the sewage from flowing into the tank 1. The fabric then enters the tank 1 through the through hole on the right side outside the water receiving tank 31. The water in the tank 1 conducts the second cleaning on the fabric. Then the fabric enters between the middle roller 332 and the lower roller 333 through the through hole on the right side wall of the water receiving tank 31. Since a spray pipe 34 is also arranged at the inlet end between the middle roller 332 and the lower roller 333, this spray pipe 34 first conducts the third cleaning on the fabric. Then the fabric enters between the middle roller 332 and the lower roller 333, and the sewage in the fabric is squeezed out. Similarly, the sewage also flows into the water receiving tank 31 and is discharged outwards through the water outlet pipe assembly 35. The fabric then enters the tank 1 through the through hole on the left side wall of the water receiving tank 31 for the fourth cleaning. After that, the fabric comes out through the through hole on the left side outside the water receiving tank 31, completing one loop. The fabric in this embodiment is a fabric belt. Then the fabric enters between the upper roller 331 and the middle roller 332 again for the next loop. This cycle continues until the pressing rollers 33 in one water washing unit 100 are fully wound with the fabric. Then the fabric enters the next water washing unit and conducts the water washing operation in the same winding belt manner until the winding of the last water washing unit 100 is completed and the fabric comes out of this water washing unit 100, and the entire water washing process is completed. Therefore, the fabric belt undergoes four cleanings during one loop. Compared with the prior art CN211339988U, there are two more cleaning processes in each loop. That is, in the same fabric belt travel, the completed cleaning process is twice that of the prior art, and the water sprayed out by the spray pipe 34 is clear water, and compared with the water containing impurities in the tank 1, the cleaning effect is better. Further, by arranging the water receiving tank 31 and the water outlet pipe assembly 35, the sewage generated in the squeezing and cleaning mechanism 3 does not flow into the tank 1, reducing the pollution to the water in the tank 1. With such an arrangement, the cleaning effect of the fabric can be effectively improved, the production efficiency can be increased, and the number of water washing units 100 can be effectively reduced, thereby reducing costs and the occupied space of the equipment.

[0030] In a preferred embodiment, as Figure 2 、 5As shown, a first driving member 101 is provided at the rear side of the support frame 32. Specifically, the first driving member 101 is a reduction motor, and the first driving member 101 is drivingly connected to the middle roller 332. The upper roller 331 and the lower roller 333 rotate drivenly following the middle roller 332. At the tops of the two support frames 32, second driving members 39 are provided. The second driving members 39 are used to adjust the distance between the respective pressing rollers 33 so that the distance is adapted to the thickness of the fabric.

[0031] In a preferred embodiment, as Figure 2 、 5 shown, the water outlet pipe assembly 35 includes a water outlet main pipe 352 and a plurality of water outlet branch pipes 351. The water outlet of each water receiving tank 31 is connected to a water outlet branch pipe 351. The outlet ends of the plurality of water outlet branch pipes 351 are connected in the same water outlet main pipe 352. The sewage finally flows out through the water outlet main pipe 352.

[0032] In a preferred embodiment, as Figures 3 - 4 shown, upper guide rollers 36 are symmetrically arranged on the left and right sides of the water receiving tank 31. Two lower guide rollers 37 are arranged at the lower end inside the tank body 1. The two lower guide rollers 37 are symmetrically arranged on both sides of the pressing roller 33. In this embodiment, by arranging two upper guide rollers 36 and two lower guide rollers 37, it is convenient to guide the winding process of the fabric.

[0033] In a preferred embodiment, as Figure 2 、 4 -5 shown, each water washing unit 100 further includes a manual cleaning assembly 4. The manual cleaning assembly 4 includes a cleaning water pipe 41 extending into the water receiving tank 31. The water outlet end of the cleaning water pipe 41 is connected to a cleaning spray head 42. A manual valve 43 is arranged in the middle of the cleaning water pipe 41. In actual use, since the sewage generated in the extrusion cleaning mechanism 3 flows into the water receiving tank 31, after a period of time, a large amount of impurities will be deposited and adhered to the inner surface of the water receiving tank 31. Therefore, in order to avoid affecting the use, in this embodiment, by arranging the manual cleaning assembly 4, it is convenient for the operator to regularly clean the water receiving tank 31. When cleaning is required, the manual valve 43 is opened, water enters the cleaning spray head 42 from the cleaning water pipe 41 and sprays out from the cleaning spray head 42 to clean the inner wall of the water receiving tank 31. The sewage after cleaning is discharged through the water outlet pipe assembly 35.

[0034] In a preferred embodiment, as Figure 3As shown, the heights of the tank walls on the left and right sides of the multiple tanks 1 increase sequentially from left to right; the water washing device further includes a tank inlet pipe 5, and the tank inlet pipe 5 is communicated with the tank 1 located on the rightmost side. In this embodiment, the leftmost side is the feeding end, and the rightmost side is the discharging end. The water in the tank closer to the right side is cleaner; therefore, setting the heights of the tank walls on the left and right sides of the multiple tanks 1 to increase sequentially from left to right, and the water in the tank inlet pipe 5 first enters the tank 1 on the rightmost side, can ensure that the water in the tank 1 flows from right to left, so that the cleanliness of the water in the tank 1 increases sequentially in the order from left to right.

[0035] In a preferred embodiment, as Figure 1 shown, the water washing device further includes an overflow port and an overflow tank 11 located below the overflow port. The overflow port and the overflow tank 11 are both arranged on the leftmost tank wall. The overflow port is communicated with the inside of the leftmost tank 1, and the bottom of the overflow tank 11 is connected with an overflow drain pipe 12. In this embodiment, since impurities will float on the surface of the water in the tank 1 and the water in the tank 1 flows from right to left, the surface impurities will also flow to the leftmost tank 1 along with the water. An overflow port and an overflow tank 11 are arranged on the leftmost tank wall, and the surface impurities can flow into the overflow tank 11 through the overflow port together with the water and be discharged through the overflow drain pipe 12, which can improve the cleanliness of the water in the tank 1.

[0036] In a preferred embodiment, as Figure 1 shown, the water washing device further includes a main water supply pipe. One end of all the spray pipes 34 is connected to the first pipe 38, and one end of all the cleaning water pipes 41 is connected to the second pipe 44. The first pipe 38, the second pipe 44, and the tank inlet pipe 5 are all communicated with the main water supply pipe, and the water supply requirement of the entire water washing device can be met by one main water supply pipe.

[0037] In a preferred embodiment, as Figure 3 shown, a liquid level detector 6 is arranged in each tank 1. In this embodiment, the liquid level detector 6 monitors the water volume in each tank 1. When the water level in one of the tanks 1 is lower than the set value, the liquid level detector 6 will feedback the result to the control system, and the control system will timely control the tank inlet pipe 5 to add water to the tank 1 to prevent the cleaning process of the fabric from being affected due to water shortage in the tank 1.

[0038] In a preferred embodiment, as Figures 4 - 5As shown, steam heating coils 7 are provided on the groove walls on both the left and right sides of each groove body 1, and a lower drain pipe 8 is connected to the bottom of each groove body 1. In this embodiment, by setting the steam heating coils 7 to heat the water in the groove body 1, the cleaning effect on the fabric can be improved; and since the impurities in the groove body 1 are likely to deposit at the bottom of the groove body, therefore, the steam heating coils 7 are arranged on the groove walls on both sides. On the one hand, it reduces the deposition of impurities on the surface of the steam heating coils 7, and on the other hand, it also facilitates the cleaning of the steam heating coils 7 and the entire groove body 1; further, a lower drain pipe 8 is connected to the bottom of the groove body 1, which is convenient for discharging the sewage in the groove body 1 when cleaning the groove body 1. Specifically, the intake ends of all the steam heating coils 7 are communicated with a steam inlet pipe 71, and the outlet ends of all the steam heating coils 7 are communicated with a steam exhaust pipe 72.

[0039] In a preferred embodiment, as Figure 4 shown, each water washing unit 100 further includes a tension adjusting mechanism 9, and the tension adjusting mechanism 9 is located above the squeezing and cleaning mechanism 3. In this embodiment, by setting the tension adjusting mechanism 9, it helps to adjust the tension of the fabric during operation and ensure the normal operation of the fabric. The specific structure of the tension adjusting mechanism 9 is the prior art in this field and will not be elaborated here.

[0040] In a preferred embodiment, as Figure 3 shown, the water washing device is respectively provided with vacuum water absorption mechanisms 10 at the fabric feeding end and the fabric discharging end.
