Description

Technical Field

[0001] This utility model relates to the field of coating, and more specifically, it relates to a low-energy coating machine. Background Technology

[0002] During the fabric production process, a surface coating treatment is required. Organic coatings are sprayed onto the fabric surface through a coating device to form a coating that adheres evenly to the fabric surface and protects it.

[0003] Common coating processes require the assistance of a coating machine. When fabric enters the coating machine for coating, because the yarn of the woven fabric is made of twisted short fibers, some short fibers are exposed during the twisting of the yarn and the weaving of the fabric, and some short fibers may even detach directly. This results in some short fiber impurities adhering to the surface of the fabric. These impurities will enter the coating machine along with the fabric, causing defects such as particles and pits on the coated surface, thus reducing the quality of the finished fabric. Generally, coating machines use brushes to clean the surface. However, because the brushes generate static electricity during the brushing of the fabric surface, when the dry brush removes impurities from the fabric surface, the static electricity will cause the impurities to remain adsorbed on the brush or the fabric. In the next brushing process, the impurities adsorbed on the brush will be transferred to the fabric, thus affecting the subsequent coating process.

[0004] Therefore, a new technical solution is needed to address the above problems. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a low-energy-consumption micro-emission coating machine.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: It includes a housing, within which a fabric transfer device is installed, through which fabric is transferred. The fabric transfer device includes two fabric pulling rods and two fabric transfer rollers. A coating device is installed at the upper end of the housing located at the center of the fabric transfer device. The coating device is perpendicular to the fabric surface between the two fabric transfer rollers. A cleaning box is installed on the inner wall of the housing at the upper right end of the fabric transfer device. Several steam ports are installed at the lower end of the cleaning box, with the openings of the steam ports facing the fabric. Several air suction ports are installed on the side wall of the cleaning box facing the fabric. A brush plate is fixedly connected to the top of the housing, with several brush bristles installed at the bottom end of the brush plate. The bristle heads are located at the left end of the air suction ports and abut against the fabric.

[0007] By adopting the above technical solution, the coating machine mainly consists of a conveying device and a coating device installed inside the housing. The conveying device transports the fabric from one end to the other. Before coating the fabric, the surface of the fabric needs to be pre-cleaned. When the fabric is conveyed into the housing, it passes through the steam port at the bottom of the cleaning chamber. The steam port sprays the water vapor generated in the cleaning chamber onto the fabric. The water vapor comes into contact with the solid impurities on the fabric, eliminating the electrostatic adsorption between the solid impurities and the fabric, and increasing the adsorption effect between solid impurities. After the fabric is sprayed with water vapor, it is brushed by the brush bristles to remove the solid particles. The brush bristles separate the solid particles from the fabric and then suck them into the cleaning chamber through the air inlet to complete the cleaning. When the fabric is transported to the middle position by the conveying device, the coating device installed at the top of the conveying device coats the fabric.

[0008] The present invention is further configured such that: the cleaning box contains water, and the cleaning box heats the water in the inner cavity.

[0009] By adopting the above technical solution, water in the cleaning box is heated to generate steam, and the heated steam is sprayed onto the surface of the fabric. A small amount of water is sprayed onto the fabric from the steam outlet, which can reduce the impact of moisture on the fabric and more effectively eliminate static electricity on small solid particles on the fabric surface.

[0010] The present invention is further configured such that: each of the left and right side walls of the housing has a fabric outlet, the two fabric outlets are located on opposite sides of the housing and at the same height.

[0011] By adopting the above technical solution, the fabric enters the housing through the right-side outlet, and after cleaning and coating, it is produced from the left-side outlet. In order to coordinate with the operation of other components, the outlets of the housing are set at the same height to facilitate the control of fabric transportation.

[0012] The present invention is further configured such that an exhaust pipe is installed at the top of the shell.

[0013] By adopting the above technical solution, when the coating device coats the fabric, the coating part will generate a large amount of organic waste gas, which will affect the workshop. The waste gas will be discharged to the waste gas treatment device through the waste gas pipe.

[0014] The present invention is further configured such that: the vertical position of the two transfer rollers is located above the two pull rods, the two transfer rollers are located between the two pull rods, and the two transfer rollers are located at the same height.

[0015] By adopting the above technical solution, the fabric is first stretched onto the coating on the guide roller by the fabric pulling rod. The fabric pulling rod ensures that the fabric transported to the guide roller is straight, which can increase the cleaning efficiency and the coating quality.

[0016] The present invention is further configured such that: the coating device includes a coating tank and a coating container, the coating container is slidably connected to the coating tank, the bottom of the coating tank has an opening, and the opening of the coating tank is connected to the coating container.

[0017] By adopting the above technical solution, the paint box slides on the paint tank, applying paint evenly to the fabric.

[0018] In summary, this utility model has the following beneficial effects: when the fabric is cleaned before coating, the fine water mist of water vapor can eliminate static electricity and improve the adsorption capacity between the lint and other solid particles on the fabric. When the brush cleans the surface of the fabric, it can clean those solid impurities more efficiently. The low-energy water vapor cleaning method results in a higher quality coating.

[0024] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Example

[0025] A low-energy micro-emission coating machine, such as Figures 1 to 3 As shown, a low-energy-consumption micro-emission coating machine includes a housing 1 and a cloth 6. A cloth transfer device is installed inside the housing 1. A coating device is installed at the upper part of the housing 1 at the center of the cloth transfer device. A cleaning box 4 is installed on the inner wall of the housing 1 at the upper right end of the cloth transfer device. Several steam ports 41 are installed at the lower end of the cleaning box 4, with the opening end of the steam port 41 facing the cloth 6. Several air intake ports 42 are installed on the side wall of the cleaning box 4 facing the cloth 6. A brush plate 5 is fixedly connected to the top of the housing 1. Several brush bristles 51 are installed at the bottom end of the brush plate 5. The head end of the brush bristles 51 is located at the left end of the air intake port 42 and abuts against the cloth 6. Cloth outlets 11 are opened on the left and right side walls of the housing 1. An exhaust pipe 12 is installed at the top of the housing 1.

[0026] like Figure 2 As shown, the cleaning box 4 produces heated water vapor, which is sprayed onto the surface of the fabric 6 through the opening of the steam port 41. The fabric transfer device includes two fabric pulling rods 21 and two fabric transfer rollers 22. The coating device includes a coating tank 31 and a coating box 32, with the coating box 32 slidably connected to the coating tank 31.

[0027] The nozzle of the coating device and the opening at the bottom of the coating tank 31 are the same opening.

[0028] The coating machine mainly consists of a fabric conveying device and a coating device installed inside the housing 1. The fabric conveying device transports the fabric 6 from one end outlet 11 to the other end outlet 11. The fabric conveying device includes a fabric conveying roller 22 and a fabric pulling rod 21. The fabric 6 is first stretched by the fabric pulling rod 21 and then conveyed to the fabric conveying roller 22 for coating. The fabric pulling rod 21 ensures that the fabric 6 transported to the fabric conveying roller 22 is straight, which can increase the cleaning efficiency and the coating quality. The fabric 6 enters the housing 1 through the right outlet 11 and is cleaned... After processing and coating, the fabric is produced from the left-side outlet 11. To coordinate with the operation of other components, the outlet 11 of the housing 1 is set at the same height for easy control of the transport of the fabric 6. Before coating the fabric 6, the surface of the fabric 6 needs to be pre-cleaned. When passing through the lower end of the cleaning box 4, if the heating tube in the cleaning box 4 is heating water, the water vapor generated by the heated water will cause the water vapor to be sprayed onto the surface of the fabric 6 due to the increased temperature and pressure of the water in the cleaning box 4. A small amount of water will be released from the steam outlet. The water vapor is sprayed onto the fabric 6. The water vapor comes into contact with the solid impurities on the fabric 6, increasing the conductivity and eliminating the electrostatic adsorption between the solid impurities (including detached short fibers and small dust particles adsorbed on the fabric 6) and the fabric 6. At the same time, it increases the adsorption effect between solid impurities (small particles adsorb together under the action of water). After the fabric 6 is sprayed with water vapor, it is brushed by the brush bristles 51 installed at the lower end of the brush plate 5, causing the solid particles to fall off. The brush bristles 51 separate the solid particles from the fabric 6, and then suck them into the cleaning box 4 through the air intake 42 to complete the cleaning. When the fabric 6 is transported to the middle position by the conveying device, the coating device installed at the upper end of the conveying device coats the fabric 6. The paint box 32 slides on the paint tank 31 to coat the fabric 6 evenly. The exhaust pipe 12 at the top of the shell 1 generates a large amount of organic waste gas when the coating device coats the fabric 6, which affects the workshop. It needs to be discharged to the waste gas treatment device through the exhaust pipe 12.
