In the process of realizing the utility model, the inventor found that at least the following problems in the prior art have not been solved, and the effect of controlling multiple coatings can be achieved by using multiple coating assemblies and built-in scrapers. The assembly and disassembly of the coating assembly and the number of uses can be controlled by the positioning assembly, so it is flexible to use and convenient to assemble and disassemble. During use, in the traditional fabric coating process, the coating in the storage hopper has poor fluidity, which causes the coating to be discharged slowly, thereby affecting the efficiency of the fabric coating, and the discharge is prone to unevenness, thereby affecting the quality of the fabric coating. For this reason, it is necessary to design a new technical solution to solve it. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings of the prior art, meet actual needs, and provide a fabric coating machine with multiple sets of scrapers to solve the current technical problems that during fabric coating processing, the coating in the storage hopper has poor fluidity, resulting in a slow coating discharge speed, which in turn affects the efficiency of fabric coating, and the coating discharge is prone to unevenness, which in turn affects the quality of fabric coating.

[0005] In order to achieve the purpose of the utility model, the technical solution adopted by the utility model is as follows: a fabric coating machine with multiple groups of scrapers is designed, including an L-shaped frame, a mounting frame is installed on one side of the L-shaped frame, the number of the mounting frames is multiple, the inner side of the mounting frame is rotatably connected to a limiting roller, a driving motor is installed on one side of the mounting frame, and the driving end of the driving motor is connected to the limiting roller; a connecting frame is installed on one side of the mounting frame, a material storage box is installed on the inner side of the connecting frame, a discharge hole is opened at the bottom of the material storage box, and one side of the material storage box is connected to the limit roller.

[0006] Preferably, baffles are fixedly connected to both sides of the surface of the scraper, and opposite ends of the two baffles correspond to the two sides of the discharge hole respectively.

[0007] Preferably, a sealing gasket is installed at one end of the box cover close to the telescopic rod, and the sealing gasket is elastic.

[0008] Preferably, an unwinding frame is installed on the top of the L-shaped frame, and a winding frame is installed on the surface of the L-shaped frame.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The utility model combines structures such as an installation frame, a limiting roller, a connecting frame, a material storage box, a material discharge hole, a scraper, a pressure plate, a spring, a telescopic rod, a box cover, an air pressure pump and an air inlet pipe. By arranging multiple groups of installation frames, multiple different limiting rollers and multiple material storage boxes for storing different coatings can be installed, so that the effect of controlling multiple coatings can be achieved. By starting the air pressure pump box, gas is rushed into the material storage box above the pressure plate to increase the air pressure in the material storage box above the pressure plate, thereby pushing the pressure plate to move downward, so that the pressure plate squeezes the coating to accelerate the coating to be evenly discharged through the material discharge hole for fabric coating, thereby avoiding the slow flow speed of the coating to affect the efficiency of the fabric coating, and avoiding the uneven discharge of the coating to affect the quality of the fabric coating. When the pressure plate moves downward, the pressure plate can clean the coating adhered to the inner wall of the storage box, thereby making the coating in the storage box completely used, thereby avoiding the waste caused by the adhered coating remaining in the storage box. At the same time, the spring is stretched during the downward movement of the pressure plate, so that when the box cover is removed, the tension of the spring pulls the pressure plate to reset and be used again.

[0017] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0018] Example 1: A fabric coating machine with multiple sets of scrapers, see Figures 1 to 3, including an L-shaped frame 1, a mounting frame 2 is installed on one side of the L-shaped frame 1, the number of the mounting frames 2 is multiple, the inner side of the mounting frame 2 is rotatably connected to a limit roller 21, a driving motor 22 is installed on one side of the mounting frame 2, and the driving end of the driving motor 22 is connected to the limit roller 21; a connecting frame 23 is installed on one side of the mounting frame 2, a material storage box 24 is installed on the inner side of the connecting frame 23, a discharge hole 27 is opened at the bottom of the material storage box 24, a scraper 28 is installed at one end of the material storage box 24, a box cover 25 is installed at the top opening of the material storage box 24, and bolts 26 are rotatably penetrated at the four corners of the surface of the box cover 25, and The four bolts 26 are all threadedly connected to the surface of the storage box 24, and an air pressure pump 3 is installed on the top of the box cover 25. The air outlet end of the air pressure pump 3 is connected to an air inlet pipe 31, and the air inlet pipe 31 runs through the box cover 25. Telescopic rods 32 are fixedly connected to both sides of the bottom of the box cover 25, and a pressure plate 34 is fixedly connected between the bottoms of the two telescopic rods 32, and springs 33 are sleeved on the outer sides of the two telescopic rods 32. The two ends of the two springs 33 are respectively connected to the box cover 25 and the pressure plate 34. By setting up multiple groups of mounting frames 2, multiple different limiting rollers 21 and multiple storage boxes 24 storing different coatings can be installed, so that To achieve the effect of controlling multiple coatings, before coating the fabric, the fabric is placed between the limiting roller 21 and the scraper 28, and then the paint in the storage box 24 is discharged from the discharge hole 27, so that when the fabric moves, the paint can be applied to the fabric through the gap between the scraper 28 and the limiting roller 21, thereby completing multi-layer coating feeding. When the amount of paint in the storage box 24 becomes smaller, the air pressure in the storage box 24 above the pressing plate 34 is increased by starting the air pressure pump 3 to rush air into the storage box 24 above the pressing plate 34, thereby pushing the pressing plate 34 to move downward, so that the pressing plate 34 can squeeze the paint to speed up The paint is discharged through the discharge hole 27 for fabric coating, thereby avoiding the slow flow of the paint affecting the efficiency of the fabric coating, and avoiding the uneven discharge of the paint affecting the quality of the fabric coating. When the pressing plate 34 moves downward, the pressing plate 34 can clean the paint adhered to the inner wall of the storage box 24, so that the paint in the storage box 24 can be completely used, thereby avoiding the waste caused by the adhered paint remaining in the storage box 24. At the same time, the spring 33 is stretched during the downward movement of the pressing plate 34, so that when the box cover 25 is removed, the tension of the spring 33 pulls the pressing plate 34 to reset and use it again.

[0019] For details, see Figure 2 Baffles 29 are fixedly connected to both sides of the surface of the scraper 28, and the opposite ends of the two baffles 29 correspond to the two sides of the discharge hole 27 respectively. Through the setting of the baffles 29, it is possible to prevent the paint from flowing out from both sides of the scraper 28 when coating the fabric, which not only prevents the overflowed paint from affecting the quality of the fabric coating, but also prevents the overflowed paint from causing waste.

[0020] For further information, see Figure 3A sealing gasket 210 is installed at one end of the box cover 25 close to the telescopic rod 32, and the sealing gasket 210 is elastic. Through the setting of the sealing gasket 210, the sealing performance of the connection between the box cover 25 and the storage box 24 is increased, thereby preventing air leakage from affecting the downward movement of the pressing plate 34.

[0021] It is worth noting that see Figure 1 A reeling frame 11 is installed on the top of the L-shaped frame 1 for reeling the required fabric, and a reeling frame 12 is installed on the surface of the L-shaped frame 1 for reeling the coated fabric.

[0022] It is worth noting that see Figure 2 A rubber pad 35 is fixedly connected to the outer side of the pressing plate 34, and the rubber pad 35 is arranged in contact with the inner wall of the storage box 24. The setting of the rubber pad 35 not only increases the sealing line between the pressing plate 34 and the inner wall of the storage box 24, but also increases the pressure plate 34 to clean the paint adhered to the inner wall of the storage box 24.

[0023] It is worth noting that see Figure 3 The pulling force of the spring 33 is greater than the friction between the pressing plate 34 and the inner wall of the storage box 24, which is used to ensure that the pulling force of the spring 33 can pull the pressing plate 34 to reset.

[0024] In addition, the components designed in the present invention are all universal standard parts or components known to technical personnel in the field. Their structures and principles can be known to technical personnel through technical manuals or through conventional experimental methods. They can be fully implemented by technical personnel in the field, and there is no need to elaborate.
