[0001] The utility model relates to the technical field of coating processing equipment, in particular to a coating baking device. Background Art

[0002] Coating refers to a method of coating a paste polymer, a molten polymer or a polymer solution on a substrate such as paper, cloth or a plastic film to obtain a composite material (film). Due to different coating thicknesses produced according to different requirements, the same machine needs to slow down the movement speed of the substrate when producing a thicker coating, so as to ensure that the thickness of the coating increases when the substrate passes under the liquid outlet, so that the coating thickness after baking is thicker, but the slow movement speed of the substrate will undoubtedly lead to a decrease in production efficiency. In view of this, the utility model proposes a coating and baking device. Utility Model Content

[0031] Example

[0032] like Figure 1 As shown, a coating and baking device proposed by the utility model includes a material transport mechanism 1, which includes a base 11, and a plurality of groups of moving rollers 12 for supporting a substrate are rotatably connected in the base 11, and the moving rollers 12 support the substrate when the substrate moves.

[0033] For further information, see Figure 2-Figure 4 The coating and baking device includes a coating mechanism 2 for discharging liquid, which is arranged on the material transport mechanism 1. The coating mechanism 2 includes a mounting frame 20, a limit block 21, a slider 22, a material box 23, and a discharge port 24. The U-shaped mounting frame 20 is installed on the top of the base 11, and the position of the mounting frame 20 is fixed. Two groups of limit blocks 21 are symmetrically installed on the inner side of the mounting frame 20, and the positions of the limit blocks 21 are also fixed. The two groups of sliders 22 are respectively slidably connected to the two groups of limit blocks 21, and the material box 23 is fixedly connected between the two groups of sliders 22. The material box 23 moves smoothly under the action of the sliders 22 and the limit blocks 21, and the limit blocks 21 and the sliders 22 are connected in a T-shaped structure, which makes the connection more stable. The material box 23 is filled with coating material, and the discharge port 24 is installed at the bottom of the material box 23 to facilitate the discharge of the coating material for coating operation. The coating mechanism 2 also includes a liquid inlet pipe 25 installed on one side of the material box 23. The liquid inlet pipe 25 is connected to a liquid delivery pipeline to facilitate adding coating materials to the material box 23. A one-way valve is installed to prevent the coating material from flowing back. The inner wall of the material box 23 is also provided with a liquid level sensor 5 for sensing the liquid level of the coating material to prevent the liquid level from being too low. The coating mechanism 2 also includes a servo motor 26, a threaded rod 27, a threaded sleeve 28, and a fixed rod 29. The servo motor 26 is installed on the top of the mounting frame 20. The output end of the servo motor 26 passes through the mounting frame 20 and is fixedly connected to the threaded rod 27. The servo motor 26 drives the threaded rod 27 to rotate after starting. The threaded sleeve 28 installed on the outer ring of the threaded rod 27 is threadedly connected to the threaded rod 27. When the threaded rod 27 rotates, it drives the threaded sleeve 28 to move. The fixing rod 29 installed on the top of the material box 23 is fixedly connected to the threaded sleeve 28. When the threaded sleeve 28 moves, it drives the material box 23 to move synchronously through the fixing rod 29, and the material box 23 moves under the limiting action of the slider 22 and the limiting block 21.

[0034] Furthermore, the above-mentioned coating and baking device also includes a baking oven 3 installed on the material transport mechanism 1 for drying the coating after drainage. After the substrate passes under the discharge port 24, the coating material is coated on the substrate. When the substrate passes through the baking oven 3, the baking oven 3 can be provided with a heating wire and a fan to bake the coating to dry it, thereby helping the coating to form quickly.

[0035] Specifically, Figure 4 and Figure 5 As shown, the coating and drying device includes an acceleration component 4 arranged on the coating mechanism 2 for controlling the discharge speed, and the acceleration component 4 includes an air cylinder 40, an air inlet pipe 41, and a barometer 42. Multiple groups of air cylinders 40 are installed on the coating mechanism 2, and the air cylinders 40 are connected to the inside of the material box 23, and the pressure is equal. The air inlet pipe 41 is arranged on one side of the air cylinder 40, and the air inlet pipe 41 is connected to the inflation device, which is convenient for inflating the air cylinder 40 to balance the pressure. At the same time, a high-pressure one-way valve is installed to prevent gas backflow. A barometer 42 is also installed on the side of the air cylinder 40 to detect the pressure in the air cylinder 40. The acceleration assembly 4 also includes a push rod motor 43, a connecting rod 44, a piston 45, and a limiting ring 46. Multiple push rod motors 43 are installed at the bottom of the mounting frame 20. The output end of the push rod motor 43 is fixedly connected to the connecting rod 44. The end of the connecting rod 44 away from the push rod motor 43 is installed with a piston 45. The push rod motor 43 drives the piston 45 to move through the connecting rod 44. The piston 45 is slidably connected to the air cylinder 40. When the piston 45 moves, it compresses the space in the air cylinder 40, thereby increasing the pressure and speeding up the discharge of the coating material at the discharge port 24. A limiting ring 46 is installed on the inner wall of each group of air cylinders 40 to limit the piston 45.

[0036] Finally, a control center 6 is also installed on one side of the base 11 in the above-mentioned coating and drying device. The liquid level sensor 5, servo motor 26, barometer 42 and push rod motor 43 are all electrically connected to the control center 6 for automatically controlling the acceleration of the discharge speed and replenishing the gas in the material box 23.

[0037] In this embodiment, the paper tape is passed between the material box 23 and the moving roller 12, and then passed between the baking oven 3 and the moving roller 12, and the paper tape is pulled and moved by the traction machine. At the same time, the servo motor 26 is started, and the servo motor 26 drives the threaded rod 27 to rotate, thereby driving the threaded sleeve 28 threadedly connected to the threaded rod 27 to move along its own length direction, and at the same time drives the material box 23 to move. The material box 23 moves synchronously under the limiting action of the slider 22 and the limit block 21, and at the same time adjusts the distance between the discharge port 24 and the paper tape. When the distance is appropriate, the traction machine is started to drive the paper tape to move. At this time, the push rod motor 43 is started to drive the piston 45 to slide downward in the gas cylinder 40 through the connecting rod 44, so that the pressure in the gas cylinder 40 and the material box 23 increases, so that the coating material at the bottom of the material box 23 is affected by the pressure and discharged faster, so that when the paper tape passes under the discharge port 24 at a uniform speed, the coating thickness can be thickened. When the liquid level sensor 5 senses that the coating material is insufficient, the coating material is injected into the material box 23 through the liquid inlet pipe 25 for replenishment. At the same time, the push rod motor 43 contracts to drive the piston 45 to move upward, and at the same time, the air inlet pipe 41 is filled with gas to ensure the stability of the pressure, so as to facilitate continuous coating operation.

[0038] The above specific embodiment is only an optional embodiment of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above embodiment, those skilled in the art can make various alternative improvements and combinations to the above specific embodiment.
