Description

Technical Field

[0001] The utility model belongs to the technical field of fabric production, and particularly relates to a fabric water washing device. Background Art

[0002] In the process of fabric production, the fabric needs to be washed with water before dyeing, so as to remove the oil agent, dirt and soil on the fabric surface through water washing.

[0003] At present, a Chinese patent with the publication number CN218372815U and the publication date of January 24, 2023 discloses a water washing device for spandex fabric, which includes a water washing tank. A plurality of fabric guide rollers are rotatably arranged in the water washing tank, and the plurality of fabric guide rollers are distributed along the length direction of the water washing tank. A first pipe is connected to the water washing tank, and a first valve is arranged on the first pipe. One end of the first pipe far away from the water washing tank is connected to a first pump, and the first pipe is connected to the negative pressure port of the first pump. The positive pressure port of the first pump is connected to a second pipe. One end of the second pipe far away from the first pump is connected to a filter tank. One side of the filter tank facing away from the second pipe is connected to a third pipe. One end of the third pipe far away from the filter tank is connected to a second pump, and the third pipe is connected to the negative pressure port of the second pump. The positive pressure port of the second pump is connected to a fourth pipe. One end of the fourth pipe far away from the second pump is connected to the water washing tank, and a second valve is arranged on the fourth pipe.

[0004] This water washing device for spandex fabric makes the fabric pass around a plurality of fabric guide rollers in turn, so that the fabric is immersed in and out of the water surface, thereby washing the fabric with water. Among them, after the fabric is washed with water, some oil stains removed from the fabric surface will float on the water surface, thus forming an oil layer on the water surface. When the fabric is washed with water and conveyed upward from below the water surface, the fabric surface passing through the water surface will pass through the oil layer again, resulting in the fabric surface being re-attached with oil liquid, which will ultimately be unfavorable for the efficient water washing of the fabric. Content of the Utility Model

[0005] The purpose of the utility model is to provide a fabric water washing device, which can reduce the possibility of the fabric coming into contact with the oil layer on the water surface when being conveyed upward from below the water surface.

[0010] A further setting of the present utility model is: A flexible filter screen with one side edge connected to the iron plate and the other side edge connected to the inner wall of the washing tank is provided on the upper side of the iron plate.

[0011] A further setting of the present utility model is: The bottom wall of the washing tank extends obliquely downward towards the side of the inlet pipe.

[0012] A further setting of the present utility model is as follows: A pressing roller for pressing the fabric against the second fabric guiding roller is provided on the upper side of the water washing box. Both ends of the pressing roller are rotatably connected to mounting arms located at the side walls of the water washing box. A guiding column extending in the horizontal direction is provided on the mounting arms. A guiding sleeve for the guiding column to pass through is provided at the side of the water washing box. A connecting disc is provided at the end of the guiding column away from the mounting arm. A connecting spring with one end connected to the connecting disc and the other end connected to the guiding sleeve is sleeved on the guiding column.

[0013] In summary, the present utility model has the following beneficial effects:

[0014] 1. The fabric enters the water washing box between two fabric feeding rollers, and then the fabric is transmitted along multiple first fabric guiding rollers. At this time, the fabric can be washed under the water surface. After the washing is completed, the fabric needs to pass through the third fabric guiding roller and the second fabric guiding roller, and then be transmitted out between the two fabric discharging rollers. When the fabric passes through the third fabric guiding roller and the second fabric guiding roller, the fabric is in a vertical transmission state. At this time, spray pipes are provided at the left and right sides of the fabric under the second fabric guiding roller on the inner wall of the water washing box. The two spray pipes can sandwich the fabric in the middle, and then the spray pipes use nozzles to spray the fabric. Since the position where the nozzles spray on the fabric is at the position where the fabric leaves the water surface, the water sprayed down will agitate the water surface around the fabric, thereby washing away the oil layer on the water surface around the fabric, avoiding the spread of the oil layer to the fabric position, and finally reducing the possibility of the fabric coming into contact with the oil layer on the water surface when being conveyed upward from below the water surface.

[0015] 2. By using a water pump provided outside the water washing box, the water pump extracts the water at the bottom of the water washing box through the water inlet pipe. Since the oil stains in the water washing box float on the water surface to form an oil layer, the water at the bottom of the water washing box does not contain oil. Then, the water is sent into the two spray pipes through the water outlet pipe. At this time, the spraying operation can be carried out with the water at the bottom of the water washing box, which is beneficial to the efficient utilization of the water in the water washing box.

[0016] 3. When the fabric is washed and the waste water in the water washing box needs to be discharged, close the first control valve of the water outlet pipe and open the second control valve of the sewage discharge pipe. Then, the water pump can discharge the water in the water washing box through the sewage discharge pipe, which is finally beneficial to the rapid discharge of the water in the water washing box.

[0017] 4. When the water inlet pipe draws water from the bottom of the water washing tank for spraying, the operator pushes the iron plate to swing through the threaded shaft and the magnet ball, thereby driving the swing plate to swing downward, so that the rubber blocking block on the lower side presses tightly against the bottom wall of the water washing tank. At this time, the swing plate can block the dirt at the bottom of the water washing tank, preventing the dirt from being drawn by the water inlet pipe for spraying; at the same time, when the water inlet pipe draws the waste water in the water washing tank and discharges it through the sewage pipe, the operator pushes the iron plate to swing in the reverse direction through the threaded shaft and the magnet ball, thereby driving the swing plate to swing upward, so that the rubber blocking block on the lower side is separated from the bottom wall of the water washing tank. Subsequently, the dirt blocked by the swing plate can cross the swing plate and be drawn away by the water inlet pipe. Finally, it is beneficial to clean the dirt on the bottom wall of the water washing tank;

[0018] 5. One side edge of the flexible filter net is connected to the iron plate, and the other side edge is connected to the inner wall of the water washing tank. When the water inlet pipe draws water from the bottom of the water washing tank for spraying, the flexible filter net can filter the water entering the water inlet pipe to prevent impurities in the water from blocking the nozzle;

[0019] 6. The bottom wall of the water washing tank extends obliquely downward toward the water inlet pipe. At this time, it is beneficial for the dirt on the bottom wall of the water washing tank to converge toward the water inlet pipe under the action of its own gravity, which is beneficial for the water inlet pipe to efficiently draw the dirt on the bottom wall of the water washing tank;

[0020] 7. When the fabric is conveyed out of the water washing tank and passes through the position of the second fabric guide roller, the pressing roller is pressed against the fabric by the elastic force of the connecting spring. At this time, the pressing roller and the second fabric guide roller can squeeze the fabric in the middle, thereby squeezing out the water on the surface of the fabric. At the same time, the squeezed water falls back into the water washing tank under the action of its own gravity. Description of the Drawings

A second cloth guiding roller 141 is rotatably connected to the fixed arm 14 through a bearing. Inside the water washing box 1 and at a position below the second cloth guiding roller 141, a third cloth guiding roller 15 is rotatably connected through a bearing. The fabric transmitted between the third cloth guiding roller 15 and the second cloth guiding roller 141 is in a vertical transmission state. At the same time, a pressing roller 5 for pressing the fabric against the second cloth guiding roller 141 is arranged on the upper side of the water washing box 1. Both ends of the pressing roller 5 are rotatably connected through bearings to mounting arms 51 located at the side walls of the water washing box 1. A guide post 52 extending in the horizontal direction is welded on the mounting arm 51. A guide sleeve 17 for the guide post 52 to pass through is fixed by bolts at the side of the water washing box 1. At the end of the guide post 52 far from the mounting arm 51, a connecting disc 521 is welded. A connecting spring 522 with one end welded to the connecting disc 521 and the other end welded to the guide sleeve 17 is sleeved on the guide post 52.

[0028] Refer to Figure 1 , on the inner wall of the water washing box 1 and at the left and right sides of the fabric below the second cloth guiding roller 141, spray pipes 2 are fixed by bolts. A plurality of spray nozzles 21 evenly spaced along the extension direction of the spray pipe 2 are installed on the lower side of the spray pipe 2. The position where the spray nozzles 21 spray on the fabric is at the position where the fabric leaves the water surface. A water pump 3 is arranged outside the water washing box 1. The water inlet of the water pump 3 is connected with a water inlet pipe 31 communicated with the bottom of the water washing box 1. At the same time, the water outlet of the water pump 3 is connected with a water outlet pipe 32 communicated with the ends of the two spray pipes 2. A first control valve 321 is installed on the water outlet pipe 32. A sewage discharge pipe 322 is also connected to the water outlet pipe 32. A second control valve 3221 is installed on the sewage discharge pipe 322.

[0029] Refer to Figure 1 , Figure 2 , the bottom wall of the water washing box 1 extends obliquely downward towards the water inlet pipe 31. Inside the water washing box 1 and near the water inlet pipe 31, a swing plate 4 with its upper side hinged inside the water washing box 1 is arranged. A rubber blocking block 41 for pressing against the bottom wall of the water washing box 1 is bonded to the lower side of the swing plate 4. At the same time, an iron plate 42 is welded on the upper side of the swing plate 4. An internal thread sleeve 16 is welded on the side wall of the water washing box 1 at the position corresponding to the iron plate 42. A threaded shaft 161 is threadedly connected inside the internal thread sleeve 16. A magnet ball 162 attracted to the iron plate 42 is bonded and fixed at the end of the threaded shaft 161. At the same time, a flexible filter net 421 with one side side bolted to the iron plate 42 and the other side side bolted to the inner wall of the water washing box 1 is arranged on the upper side of the iron plate 42.

[0030] Principle: The fabric enters the water washing box 1 between two fabric feeding rollers 12, and then the fabric is transported along multiple first fabric guiding rollers 11. At this time, the fabric can be washed under the water surface. After the washing is completed, the fabric needs to pass through the third fabric guiding roller 15 and the second fabric guiding roller 141, and then be transmitted out between two fabric discharging rollers 13. When the fabric passes through the third fabric guiding roller 15 and the second fabric guiding roller 141, the fabric is in a vertical transmission state. At this time, spray pipes 2 are arranged at the left and right sides of the fabric on the inner wall of the water washing box 1 and below the second fabric guiding roller 141. The two spray pipes 2 can clamp the fabric in the middle. Then, the spray pipes 2 use the nozzles 21 to spray the fabric. Since the position where the nozzles 21 spray on the fabric is at the position where the fabric leaves the water surface, the water sprayed down will agitate the water surface around the fabric, thereby washing away the oil layer on the water surface around the fabric, avoiding the spread of the oil layer to the fabric position, and finally reducing the possibility of the fabric contacting the water surface oil layer when being conveyed upward from below the water surface.

[0031] Among them, the water pump 3 uses the water inlet pipe 31 to extract the water at the bottom of the water washing box 1. Since the oil stains in the water washing box 1 float on the water surface to form an oil layer, there will be no oil liquid in the water at the bottom of the water washing box 1. Then, the water is sent into the two spray pipes 2 through the water outlet pipe 32. At this time, the spraying operation can be carried out through the water at the bottom of the water washing box 1, which is beneficial to the efficient utilization of the water in the water washing box 1.

[0032] At the same time, when the water inlet pipe 31 extracts the water at the bottom of the water washing box 1 for spraying, the first control valve 321 of the water outlet pipe 32 is opened and the second control valve 3221 of the sewage discharge pipe 322 is closed. The operator pushes the iron plate 42 to swing through the threaded shaft 161 and the magnet ball 162, thereby driving the swing plate 4 to swing downward, so that the lower rubber blocking block 41 abuts against the bottom wall of the water washing box 1. At this time, the swing plate 4 can block the dirt at the bottom of the water washing box 1 to avoid the dirt being extracted by the water inlet pipe 31 for spraying. At the same time, when the water inlet pipe 31 extracts the waste water in the water washing box 1 and discharges it through the sewage discharge pipe 322, the first control valve 321 of the water outlet pipe 32 is closed and the second control valve 3221 of the sewage discharge pipe 322 is opened. The operator pushes the iron plate 42 to swing in the reverse direction through the threaded shaft 161 and the magnet ball 162, thereby driving the swing plate 4 to swing upward, so that the lower rubber blocking block 41 is separated from the bottom wall of the water washing box 1. Then, the dirt blocked by the swing plate 4 can cross the swing plate 4 and be drawn away by the water inlet pipe 31. Finally, it is beneficial to clean the dirt on the bottom wall of the water washing box 1.
