Description

Technical Field

[0001] This application relates to the field of coating equipment technology, and more particularly to a nonwoven fabric coating equipment. Background Technology

[0002] The published patent document CN215197952U discloses a nonwoven fabric coating machine for continuous production. The technical solution includes a substrate, a support frame fixedly connected to the top of the substrate, a first roller at one end of the support frame, a second roller at the end of the support frame away from the first roller, limiting support components at the bottom of both the first and second rollers, and a limiting coating component at the top of the support frame. The limiting coating component includes a coating box and a drying box. A first square groove is formed on the surface of one end of the top of the support frame. The beneficial effects of this nonwoven fabric coating machine for continuous production are: it reduces the inconvenience for operators and avoids the common problem in existing continuous production nonwoven fabric coating machines where the position of the nonwoven fabric on the roller easily shifts after coating for a period of time, causing wrinkles in the nonwoven fabric and preventing coating in the wrinkled areas, thus affecting the coating quality and efficiency.

[0003] During the coating process, the coating box may apply excessive coating to the nonwoven fabric. This unused coating may drip, causing waste and pollution. Furthermore, oversaturated coating on the nonwoven fabric will increase the drying difficulty in the drying box, resulting in poor drying effect and affecting the coating quality. Therefore, this application provides a nonwoven fabric coating device. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a nonwoven fabric coating device that overcomes these deficiencies. The device aims to solve the problems that, during the coating process, the coating box may apply excessive coating to the nonwoven fabric, resulting in unused coating that may drip, causing waste and pollution. Furthermore, oversaturated coating on the nonwoven fabric increases the drying difficulty in the drying box, leading to poor drying results and affecting the coating quality.

[0005] To achieve the above objectives, this application provides the following technical solution: a nonwoven fabric coating device, comprising a first roller frame and a second roller frame, with fabric roll rollers rotatably connected above both the first and second roller frames. A coating box is placed on one side of the first roller frame, and a drying box is placed on one side of the second roller frame. A support is placed between the coating box and the drying box. A paint recovery mechanism is provided on the top of the support. The paint recovery mechanism includes a paint recovery box, which is fixedly installed on the top of the support. Guide tubes are fixedly connected to both sides of the paint recovery box. The paint recovery box is connected to the coating box and the drying box respectively through two sets of guide tubes. A rotating roller is rotatably connected inside the paint recovery box. An adjustment groove is provided on the inner wall of the paint recovery box. An adjustment block is movably connected to the adjustment groove. A squeezing roller is rotatably connected to one side of the adjustment block. Two sets of springs are installed on the top of the adjustment block, and a rectangular block is installed on the top of the springs. The rectangular block is located at the adjustment groove.

[0006] By adopting the above technical solution, driven by external equipment, the nonwoven fabric sequentially passes through the coating box, the coating recovery mechanism, and the drying box. Two sets of fabric roll rollers guide the nonwoven fabric, which is then coated with coating material in the coating box. When the coated nonwoven fabric passes between the rotating roller and the extrusion roller, the adjusting block connected to the extrusion roller has a range of elastic movement under the action of two sets of springs. This allows the extrusion roller to work in conjunction with the rotating roller to extrude the coating material from the nonwoven fabric, reducing coating loss. Simultaneously, the extrusion roller and the rotating roller rotate synchronously through the nonwoven fabric during the coating process, ensuring that the movement of the nonwoven fabric is not affected. This effectively recovers excess coating material generated during the coating process in the coating box, reducing coating waste, improving the drying effect of the subsequent drying box, and enhancing the coating quality of the nonwoven fabric.

[0007] As a preferred technical solution of this application, a pressure regulating mechanism is provided on the top of the paint recycling bin. The pressure regulating mechanism includes a rotating rod, which is rotatably connected to the top of the paint recycling bin. A bearing is installed at the connection between the rotating rod and the paint recycling bin. A thread is provided at the bottom of the rotating rod, and the rectangular block is threadedly connected to the rotating rod through the thread.

[0008] By adopting the above technical solution, the rectangular block moves up and down under the action of the screw by rotating the rotating rod, thereby adjusting the compression degree of the spring between the rectangular block and the adjusting block, thus adjusting the squeezing force of the extrusion roller on the non-woven fabric coating, improving the practicality during use.

[0009] As a preferred technical solution of this application, a collection box is fixedly installed in the middle of the bracket, the collection box is connected to the paint recycling box through a feeding pipe, a receiving pump is fixedly installed inside the collection box, and a conveying pipe is connected to the coating box through the receiving pump.

[0010] By adopting the above technical solution, the paint squeezed in the paint recycling box enters the collection box through the feeding pipe. When a certain amount is collected, the collection pump is started to transport the recycled paint back to the coating box through the conveying pipe for reuse. This helps to reduce costs and improve economic efficiency.

[0011] As a preferred technical solution of this application, a first filter layer is slidably connected to the top of the collection box, and a second filter layer is slidably connected to the inside of the collection box below the first filter layer.

[0012] By adopting the above technical solution, the paint falling through the feed pipe passes through the first filter layer and the second filter layer for double filtration, effectively removing impurities such as lint and debris contained in the paint, and improving the cleanliness of the reused paint.

[0013] As a preferred technical solution of this application, a liquid level sensor is fixedly installed at the bottom of the collection box below the second filter layer, a controller is fixedly installed on one side of the paint recovery box, and the controller is signal-connected to the liquid level sensor and electrically connected to the control terminal of the receiving pump.

[0014] By adopting the above technical solution, when the level sensor detects that the paint in the collection box has reached the preset amount, the level sensor sends a signal to the controller, which then controls the start of the receiving pump to transport the filtered paint back to the coating box through the conveying pipe, thus completing the automated reuse of the paint, reducing the workload of workers, and improving the automation level of the device.

[0015] As a preferred embodiment of this application, the spring is provided with a telescopic guide rod inside, one end of the telescopic guide rod is installed at the bottom end of the rectangular block, and the telescopic end of the telescopic guide rod is installed at the top end of the adjusting block.

[0016] By adopting the above technical solution, the telescopic guide rod plays a guiding role in the elastic extension and contraction of the spring, which helps to extend the service life of the spring.

[0017] As a preferred technical solution of this application, guide blocks are fixedly installed on both sides of the rectangular block, and the inner wall of the paint recycling box is provided with guide grooves that match the guide blocks.

[0018] By adopting the above technical solution, when the vertical displacement of the rectangular block is adjusted, the guide block moves in conjunction with the rectangular block. The guide block moves along the guide groove to guide the displacement of the rectangular block, thereby improving the stability of the rectangular block during movement.

[0019] As a preferred technical solution of this application, the inner bottom wall of the paint recycling bin is inclined.

[0020] By adopting the above technical solution, the inclined design of the inner bottom wall of the paint recycling box facilitates the rapid sliding of the squeezed paint to the discharge pipe, thereby improving the paint collection efficiency.

[0021] The beneficial effects of this application are:

[0022] 1. Driven by external equipment, the nonwoven fabric sequentially passes through the coating box, the coating recovery mechanism, and the drying box. Two sets of fabric roll rollers guide the nonwoven fabric. The coating box coats the nonwoven fabric with coating. As the coated nonwoven fabric passes between the rotating roller and the extrusion roller, the adjusting block connected to the extrusion roller has a range of elastic movement under the action of two sets of springs. This allows the extrusion roller to work in conjunction with the rotating roller to squeeze the coating off the nonwoven fabric, reducing coating loss. Simultaneously, the extrusion roller and the rotating roller rotate synchronously through the nonwoven fabric during the coating process, ensuring that the movement of the nonwoven fabric is not affected. This effectively recovers excess coating generated during the coating process in the coating box, reducing coating waste, improving the drying effect of the subsequent drying box, and enhancing the coating quality of the nonwoven fabric.

[0023] 2. By rotating the rotating rod, the rectangular block moves up and down under the action of the screw, thereby adjusting the compression degree of the spring between the rectangular block and the adjusting block, thus adjusting the squeezing force of the extrusion roller on the non-woven coating, improving the practicality during use.

[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] Reference Figure 1-4 A nonwoven fabric coating device includes a first roller frame 1 and a second roller frame 2. Fabric roll rollers 3 are rotatably connected above both the first roller frame 1 and the second roller frame 2. A coating box 6 is placed on one side of the first roller frame 1, and a drying box 7 is placed on one side of the second roller frame 2. A support 8 is placed between the coating box 6 and the drying box 7. A paint recovery mechanism 9 is provided on the top of the support 8. The paint recovery mechanism 9 includes a paint recovery box 901, which is fixedly installed on the top of the support 8. Guide tubes 902 are fixedly connected to both sides of the paint recovery box 901. The paint recovery box 901 is connected to the coating box 6 and the drying box 7 respectively through two sets of guide tubes 902. The material recycling bin 901 is rotatably connected to a rotating roller 903. The inner wall of the paint recycling bin 901 is provided with an adjustment groove 906. An adjustment block 905 is movably connected to the adjustment groove 906. A squeezing roller 904 is rotatably connected to one side of the adjustment block 905. Two sets of springs 907 are installed on the top of the adjustment block 905. A rectangular block 908 is installed on the top of the springs 907. The rectangular block 908 is located at the adjustment groove 906. A collection box 12 is fixedly installed in the middle of the bracket 8. The collection box 12 is connected to the paint recycling bin 901 through a discharge pipe 11. A receiving pump 13 is fixedly installed inside the collection box 12. A conveying pipe 14 is connected to the coating box 6 through the receiving pump 13.

[0031] Driven by external equipment, the nonwoven fabric sequentially passes through the coating box 6, the coating recovery mechanism 9, and the drying box 7. Two sets of fabric roll rollers 3 guide the nonwoven fabric, and the coating box 6 coats it with coating material. After coating, the nonwoven fabric passes between the rotating roller 903 and the pressing roller 904. The adjusting block 905 connected to the pressing roller 904 has a range of elastic movement under the action of two sets of springs 907, allowing the pressing roller 904 to work in conjunction with the rotating roller 903 to press the coating material onto the nonwoven fabric, reducing coating loss. Simultaneously, the pressing roller 904 and the rotating roller 903... During the coating extrusion process, the nonwoven fabric is linked to rotate synchronously, thus not affecting the movement of the nonwoven fabric. This effectively recovers excess coating generated during the coating process in the coating box 6, reducing coating waste, improving the drying effect of the subsequent drying box 7, and enhancing the coating quality of the nonwoven fabric. The coating extruded in the coating recovery box 901 enters the collection box 12 through the feeding pipe 11. When a certain amount is collected, the receiving pump 13 is activated to transport the recovered coating back to the coating box 6 through the conveying pipe 14 for reuse, thereby helping to reduce costs and improve economic efficiency.

[0032] Reference Figure 1-3 The top of the paint recycling bin 901 is provided with a pressure regulating mechanism 10. The pressure regulating mechanism 10 includes a rotating rod 1001, which is rotatably connected to the top of the paint recycling bin 901. A bearing 1002 is installed at the connection between the rotating rod 1001 and the paint recycling bin 901. A thread 1003 is provided at the bottom of the rotating rod 1001. A rectangular block 908 is threadedly connected to the rotating rod 1001 through the thread 1003. The top of the collection bin 12 is slidably connected with a first filter layer 15, and the inside of the collection bin 12, located below the first filter layer 15, is slidably connected with a second filter layer 16.

[0033] By rotating the rotating rod 1001, the rectangular block 908 moves up and down under the action of the thread 1003, thereby adjusting the compression degree of the spring 907 between the rectangular block 908 and the adjusting block 905, thus adjusting the squeezing force of the extrusion roller 904 on the non-woven fabric coating, improving its practicality during use; the coating falling through the feed pipe 11 passes through the first filter layer 15 and the second filter layer 16 for double filtration, effectively removing impurities such as lint and debris contained in the coating, improving the cleanliness of the reused coating.

[0034] Reference Figure 2-4A liquid level sensor 17 is fixedly installed at the bottom of the collection box 12, below the second filter layer 16. A controller 18 is fixedly installed on one side of the paint recovery box 901, and the controller 18 is signal-connected to the liquid level sensor 17. The controller 18 is also electrically connected to the control terminal of the receiving pump 13. Guide blocks 20 are fixedly installed on both sides of the rectangular block 908. A guide groove 21 matching the guide block 20 is opened on the inner wall of the paint recovery box 901. When the liquid level sensor 17 detects that the paint in the collection box 12 has reached the preset amount, the liquid level sensor 17 sends a signal to the controller 18. The controller 18 controls the receiving pump 13 to start, and the filtered paint is transported back to the coating box 6 through the conveying pipe 14, completing the automated reuse of paint, reducing the workload of workers, and improving the automation level of the device. When the vertical displacement of the rectangular block 908 is adjusted, the rectangular block 908 moves in conjunction with the guide block 20. The guide block 20 moves along the guide groove 21 to guide the displacement of the rectangular block 908, improving the stability of the rectangular block 908 during movement.

[0035] Reference Figure 2-4 The spring 907 has a telescopic guide rod 19 inside. One end of the telescopic guide rod 19 is installed at the bottom of the rectangular block 908, and the telescopic end of the telescopic guide rod 19 is installed at the top of the adjusting block 905. The bottom wall of the paint recycling box 901 is inclined. The telescopic guide rod 19 guides the spring 907 during its elastic extension and contraction, which helps to extend the service life of the spring 907. The inclined bottom wall of the paint recycling box 901 facilitates the rapid sliding of the squeezed paint to the discharge pipe 11, improving the collection efficiency of the paint.

[0036] Working principle: Driven by external equipment, the nonwoven fabric passes sequentially through the coating box 6, the coating recovery mechanism 9, and the drying box 7. The nonwoven fabric is guided by two sets of fabric roll rollers 3. The coating box 6 coats the nonwoven fabric with coating. When the coated nonwoven fabric passes between the rotating roller 903 and the extrusion roller 904, the adjusting block 905 connected to the extrusion roller 904 has a range of elastic movement under the action of two sets of springs 907. This allows the extrusion roller 904 to work with the rotating roller 903 to extrude the coating on the nonwoven fabric. By rotating the rotating rod 1001, the rectangular block 908 moves up and down under the action of the thread 1003, thereby adjusting the compression degree of the spring 907 between the rectangular block 908 and the adjusting block 905, and thus adjusting the extrusion force of the extrusion roller 904 on the coating of the nonwoven fabric.

[0037] The paint squeezed in the paint recycling box 901 enters the collection box 12 through the feed pipe 11. When a certain amount is collected, the collection pump 13 is started to transport the recycled paint back to the coating box 6 through the conveying pipe 14 for reuse. The paint falling through the feed pipe 11 passes through the first filter layer 15 and the second filter layer 16 for double filtration.

[0038] Meanwhile, when the liquid level sensor 17 detects that the amount of paint in the collection box 12 has reached the preset amount, the liquid level sensor 17 sends a signal to the controller 18, and the controller 18 controls the start of the receiving pump 13 to transport the filtered paint back to the coating box 6 through the conveying pipe 14; the telescopic guide rod 19 plays a guiding role when the spring 907 is elastically extended and retracted.

[0039] In addition, when the rectangular block 908 is adjusted up and down, the rectangular block 908 moves in conjunction with the guide block 20, and the guide block 20 moves along the guide groove 21 to guide the displacement of the rectangular block 908; the inclined design of the inner bottom wall of the paint recycling box 901 facilitates the rapid sliding of the squeezed paint to the discharge pipe 11.
