[0020] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0021] like Figure 1-Figure 3 As shown, an embodiment of the present application provides a water-based artificial leather production cleaning device, comprising: A conveying frame 1, on which a conveying roller 101 and an extruding coating roller 102 are rotatably mounted, wherein the extruding coating roller 102 is arranged on the upper side of the conveying roller 101, and the conveying roller 101 is used for conveying the cloth, and is mainly connected to an external motor for rotating conveying, while the extruding coating roller 102 is used as an auxiliary conveyor to simultaneously extrude the cloth and the slurry coated thereon, so as to ensure the close adhesion of the materials, avoid the materials from falling off during the conveying process, and improve the coating quality, and the conveying roller 101 and the extruding coating roller 102 are connected by a gear transmission; The material hopper 2 includes a hollow frame 201 fixedly connected to one side of the conveying frame 1, a material trough 202 is constructed in the hollow frame 201, a discharge frame 203 connected to the bottom of the material trough 202 is arranged on the side of the material trough 202 opposite to the conveying frame 1, and a stirring scraper 3 is arranged in the material trough 202. The hollow frame 201 is connected to one side of the conveying frame 1 as a whole and wrapped around the bottom of the conveying roller 101, and the material trough 202 is a frustum-shaped structure with a small bottom and a large top, one side of which is wrapped around part of the conveying roller 101. When the slurry is injected into the material trough 202, it will cover a part of the conveying roller 101, which is convenient for the contact and coating of the material and the cloth. The interior of the hollow frame 201 is a hollow structure, and its body is a metal shell, such as steel, which is convenient for heat conduction, and the stirring scraper 3 is used to stir the material to ensure the continuous flow of the material, avoid static deposition, reduce the probability of solidification, and increase safety; The heating jet component 4 has a water storage chamber 204 in the hollow frame 201, and an air inlet 205 connected to the water storage chamber 204 is configured at the bottom of the material tank 202. The heating jet component 4 includes a water inlet pipe 401 connected to the hollow frame 201 and connected to the water storage chamber 204. A heating strip 402 is fixedly connected to the bottom of the water storage chamber 204. A suspension bracket 403 is fixedly connected to the bottom of the water storage chamber 204. A floating valve assembly 5 for controlling the opening and closing of the air inlet 205 is installed on the suspension bracket 403. It should be noted that the air inlet 205 is normally opened by the floating valve. The component 5 is sealed to prevent the loss of materials, and the water storage chamber 204 in the hollow frame 201 is used to store water. The water source can be used to heat the hollow frame 201, thereby indirectly increasing the temperature of the materials, further preventing the materials from solidifying and increasing safety. At the same time, in the early stage of cleaning the material tank 202, the heating strip 402 can be used to heat the water in the water storage chamber 204 to boiling to generate steam, and then the floating valve component 5 is used to open the air inlet 205, so that the steam is sprayed on the inner wall of the material tank 202 to soften the solidified materials, thereby improving the cleaning efficiency; The spray assembly 6 includes a flap 601 hinged at the top corner of the hollow frame 201, the flap 601 is used to cover the material tank 202 and the coating roller 102, a water spray pipe 602 is fixedly connected to the inner side of the flap 601, a movable hose 603 is installed at one end of the hollow frame 201, and the movable hose 603 is used to connect the water spray pipe 602 and the water storage chamber 204. The water source in the hollow frame 201 can not only be used to heat the material, but also can be used as the water source of the water spray pipe 602, thereby reducing the waste of water resources. When replacing new materials, the old materials need to be completely cleaned to avoid affecting the color and coating quality of the new materials. The personnel only need to snap the flip cover 601 onto the hollow frame 201, then open the movable hose 603 and start the conveying roller 101 to rotate it, and then use the water spray pipe 602 to spray and clean the material trough 202 and the extrusion coating roller 102 comprehensively, and finally use the discharge frame 203 to discharge the sewage. There is no need for manual hand-held water pipes to flush, which saves a lot of manpower and time and increases the convenience of the device.

[0022] like Figure 5 As shown, in some embodiments, an adjusting member 7 for controlling the thickness of the coating on the fabric is also included. The conveying frame 1 is U-shaped and has vertical grooves 103 at both ends of its top. The adjusting member 7 includes a spring slider 701 slidably inserted in the vertical groove 103. The coating extrusion roller 102 is rotatably installed between the two spring sliders 701. A mounting block 702 covering the vertical groove 103 is connected to the top of the conveying frame 1. An adjusting screw 703 rotatably connected to the spring slider 701 is installed through a thread on the mounting block 702. It should be noted that the spring slider 701 includes an upper slider and a lower slider. The coating roller 102 is connected to the lower slider in a sliding fit with a support spring connected therebetween, and the adjusting screw 703 is connected to the upper slider. The position of the upper slider can be adjusted by using the threaded fit of the adjusting screw 703 and the mounting block 702, so that the distance between the coating roller 102 and the conveying roller 101 can be changed over a large range to adapt to the thickness of different fabrics. By setting a support spring, the position of the upper slider can be adjusted in a small range by adjusting the screw 703, so as to change the squeezing force of the coating roller 102 on the fabric, thereby controlling the coating thickness of the material and increasing the flexibility of the device.

[0023] like Figure 5As shown, in some embodiments, the bottom of the conveying frame 1 is constructed with two extension grooves 104 inclined toward the vertical groove 103, and a moving block 105 is slidably installed in the extension groove 104, and an auxiliary shaft 106 is rotatably installed between the two moving blocks 105. A buckle plate 107 is connected to the open end of the extension groove 104, and an adjusting screw 108 rotatably connected to the moving block 105 is installed through a thread on the buckle plate 107. It should be noted that the auxiliary shaft 106 is arranged between the conveying roller 101 and the extrusion coating roller 102, and can be moved and adjusted along the extension groove 104 to change the height difference with the extrusion coating roller 102, thereby adjusting the tension of the cloth, increasing the flexibility of the device, and the strength of the cloth against the surface of the extrusion coating roller 102. In conjunction with the spring slider 701, the pressure of the extrusion coating roller 102 on the coating layer can be more flexibly adjusted to improve the coating accuracy.

[0024] like Figure 6 As shown, in some embodiments, the discharge frame 203 includes a plurality of horizontal frames 2031 arranged in an array along the length direction of the hollow frame 201, one end of the horizontal frame 2031 is connected to the bottom of the material trough 202 and the other end is fixedly connected to the horizontal frame 2032, and the horizontal frame 2032 is sleeved with a rake plate 2033 inserted in the plurality of horizontal frames 2031. The arrangement of the plurality of horizontal frames 2031 can increase the drainage volume, the horizontal frame 2031 passes through the water storage cavity 204 and is connected to the bottom of the material trough 202, and the port is arranged on the bottom surface of the material trough 202, which makes it easier to discharge the sewage, the rake plate 2033 includes a rectangular frame with an opening at one end, and a plurality of plug-in plates are connected to the opening of the rectangular frame, the rectangular frame can be buckled and sleeved on the port of the horizontal frame 2032, and the plug-in plate can be inserted in each horizontal frame 2031 and its port is tightly sealed, so as to increase the contact area between the two and increase the sealing performance. At the same time, the structure only relies on plug-in cooperation, which can be easily pulled out and conveniently drained.

[0025] like Figure 1-Figure 2As shown, in some embodiments, the stirring scraper 3 includes a scraper frame 301 slidably installed in the material tank 202, the scraper frame 301 is trapezoidal in shape, and one end is configured with an arc groove for wrapping the conveying roller 101 and squeezing the coating roller 102, the edges of the scraper frame 301 are configured with bevels to reduce the contact area with the inner wall of the material tank 202 and ensure the scraping quality, a bearing ring 302 is rotatably installed on the scraper frame 301, and a stirring rod 303 suspended in the material tank 202 is slidably installed between the two bearing rings 302, and a push screw 304 is threadedly installed at both ends of the hollow frame 201, and the end of the push screw 304 is configured with a connecting hole 305 slidably sleeved on both ends of the stirring rod 303. It should be noted that one end of the push screw 304 is connected to a rotating handle, and the other end of the push screw 304 can be connected to an external motor (not shown in the figure), so that the device can be controlled not only manually but also electrically, increasing the flexibility of the device. When the equipment performs a coating operation, The two scraper frames 301 are moved synchronously relative to each other, and the materials can be concentrated toward the blades of the stirring rod 303, thereby improving the stirring effect. In this process, the scraper frame 301 can also scrape the inner wall of the material trough 202 and the surfaces of the conveying roller 101 and the extruding coating roller 102 to avoid material deposition on the edge of the cloth, increase safety, and ensure the quality of subsequent coating. At the same time, the distance between the two scraper frames 301 can also change with the width of the cloth, always contacting the edge of the cloth, limiting the wrapping of the cloth coating, reducing the diffusion of the slurry toward the two sides of the cloth, and further reducing the edge deposition of the slurry on the conveying roller 101 and the extruding coating roller 102.

[0026] like Figure 7-Figure 8 As shown, in some embodiments, ring blocks 2011 are rotatably installed at both ends of the hollow frame 201, the push screw 304 threads through the ring block 2011, and a plurality of slots 2012 are constructed along the circumferential array of the outer side of the ring block 2011, and a clamping column 2013 for engaging with the slot 2012 is slidably installed on the upper side of the hollow frame 201, and a limiting spring 2014 is connected between the top of the clamping column 2013 and the top surface of the hollow frame 201, the ring block 2011 and the push screw 304 are threadedly matched, and the ring block 2011 and the hollow frame 201 are limitedly connected by the clamping column 2013 and the slot 2012, and the stirring rod 303 can be flexibly switched between the state of single rotation of the stirring rod 303 and the state of simultaneous movement of the stirring rod 303 and the scraper frame 301 to adapt to different scenarios and increase the adaptability of the device.

[0027] like Figure 4 , Fig. 9 and Fig.10 As shown, in some embodiments, the floating valve assembly 5 includes a horizontal plate 501 arranged in parallel above the suspended bracket 403, and a plurality of sealing columns 502 for blocking the air inlet 205 are connected to the horizontal plate 501 in an array along its length direction. The bottom end of the sealing column 502 slides through the suspended bracket 403, and a plurality of tightening springs 503 sleeved on the sealing column 502 are connected between the horizontal plate 501 and the suspended bracket 403. A floating member 5 for driving the horizontal plate 501 to move up and down is installed on the suspended bracket 403. 04. It should be noted that under normal circumstances, the tightening spring 503 always exerts a downward pulling force on the horizontal plate 501, and the floating member 504 is a floating plate set up on the suspended bracket 403. Only when the water level exceeds the suspended bracket 403 will the floating plate move up, thereby driving the sealing column 502 to move up synchronously, so as to control the opening and closing operation of the air inlet 205. No additional electric drive is required, and only the amount of water entering the water storage chamber 204 needs to be controlled, which increases the convenience of the device, saves electricity consumption, and increases environmental protection and energy saving.

[0028] like Figure 2 , Figure 4 and Fig.10As shown, in some embodiments, an upper conical groove 2051 is constructed at one end of the air inlet 205 located in the material tank 202, and a lower conical groove 2052 is constructed at one end of the air inlet 205 located in the water storage chamber 204, which is arranged opposite to the upper conical groove 2051. The sealing column 502 includes a column rod 5021 that passes through the horizontal plate 501, and a lower conical block 5022 connected to the horizontal plate 501 is constructed on the column rod 5021. A nail rod 5023 is threadedly inserted at the upper end of the column rod 5021, and an upper conical block 5024 inserted into the upper conical groove 2051 is constructed on the nail rod 5023. The floating member 504 is inserted between the suspended bracket 403 and the horizontal plate 501. It should be noted that the floating valve assembly 5 has three states, one of which is The first is that the upper cone block 5024 is located in the upper cone groove 2051. At this time, the tightening spring 503 is in a contracted state, and the column rod 5021 is always pulled downward to seal the air inlet 205. The second is that the upper cone block 5024 is separated from the upper cone groove 2051, and the lower cone block 5022 has not entered the lower cone groove 2052. At this time, the column rod 5021 is active in the middle of the air inlet 205, and the air inlet 205 is in an open state. The third is that the lower cone block 5022 enters the lower cone groove 2052. At this time, the buoyancy of the floating member 504 is used to push the cross plate 501 upward to fit the inner wall of the water storage chamber 204, and the air inlet 205 is closed again. These three states are used for different stages of the cleaning equipment, specifically, when it is needed When cleaning the material tank 202, firstly, the liquid slurry needs to be completely discharged through the discharge frame 203. During this period, the floating valve assembly 5 is in the first state. Then, water is injected into the water storage chamber 204. At this time, the water level is below the suspended bracket 403. At the same time, the heating strip 402 is used to heat the water source until it boils and generates steam. The steam will continuously push the upper cone block 5024 to intermittently detach from the upper cone groove 2051 through air pressure, so that the steam is intermittently sprayed on the inner wall of the material tank 202 to soften the solidified material on the inner wall of the material tank 202. Then, water is continuously injected into the water storage chamber 204 until the floating valve assembly 5 is in the third state. The air inlet 205 is blocked again. Because the interior of the hollow frame 201 is U-shaped, The water storage chamber 204 will therefore experience a second state during this process, and at the same time, due to the water pressure, part of the water source will be squeezed out of the air inlet 205 into the material trough 202 to further soak and soften the material, until it is completely in the third state. At this time, the water storage chamber 204 is full of water, and the floating member 504 uses buoyancy to always resist the upward movement of the horizontal plate 501, effectively blocking the air inlet 205. At this time, the flip cover 601 can be buckled, and the movable hose 603 can be used to provide water for the water spray pipe 602 to spray the material trough 202.
