[0002] A coating machine is a device that coats a roll of base material with a specific functional glue, coating, ink, etc., dries it, and then cuts it into sheets or rewinds it. It is mainly used for surface coating of films, papers, fabrics, textiles, electronic products, etc. to change the properties, appearance or functions of the base material. The preheating device of the diaphragm coating machine is a crucial part of the coating process. Its main function is to increase the temperature of the coating material (such as the diaphragm) to improve its fluidity and coating performance, thereby ensuring the smooth progress of the coating process and the improvement of the coating quality.

[0003] Currently, for the preheating device of the diaphragm coating machine, the preheating method is single. During preheating, mostly only the coating material can be preheated, and the preheating is insufficient. Problems often occur frequently during production, resulting in a decline in the coating quality. Moreover, only preheating the coating material will also cause bubbles during coating, and the uniformity of coating cannot be guaranteed, which is not conducive to production.

[0004] Therefore, it is very necessary to propose a new preheating device for the diaphragm coating machine to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a preheating device for a diaphragm coating machine to solve the problems proposed in the above background technique.

Detailed Embodiments

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0018] As Figures 1 - 3 shown, the present invention provides a preheating device for a diaphragm coater, including a conveyor 1. A steam generator 2 is provided on the side wall of the conveyor 1. A preheating shell 3 is fixedly connected to the top surface of the conveyor 1. A preheating assembly 4 is arranged inside the preheating shell 3. The preheating assembly 4 includes a preheating box 41 fixedly connected to one side of the inner wall of the preheating shell 3, a moving frame 43 arranged on the other side of the inner wall of the preheating shell 3. A serpentine tube 42 is arranged inside the preheating box 41. A storage cavity 47 is formed inside the serpentine tube 42. An exhaust pipe 22 and a connecting pipe 46 are fixedly connected and communicated on both sides of the serpentine tube 42. A rotating roller 44 is rotatably connected in a groove on the bottom surface of the moving frame 43. A cylindrical cavity 45 is formed inside the rotating roller 44. An intake pipe 21 and a connecting pipe 46 are rotatably connected on both sides of the rotating roller 44. The intake pipe 21 and the exhaust pipe 22 are fixedly connected and communicated with the steam generator 2; the preheating assembly 4 can preheat the coating material and the diaphragm. The preheating method is diverse, the preheating is sufficient, and problems are not likely to occur during production, avoiding the decline of coating quality. By controlling the steam generator 2, the temperature can be accurately adjusted, reducing temperature fluctuations and ensuring the coating quality. The steam generator 2 transports steam through the intake pipe 21 into the cylindrical cavity 45 of the rotating roller 44. The cylindrical cavity 45 is preheated by the steam. When coating, the rotating roller 44 is adjusted to contact the conveyor belt of the conveyor 1. At this time, the rotating roller 44 can preheat the diaphragm conveyed by the conveyor belt. During the preheating process, the diaphragm can also be flattened. After the diaphragm is preheated, its bonding force can be enhanced, the bubbles generated during the coating process can be reduced, and the uniformity of the coating can be improved, ensuring the coating quality. The steam flows through the cylindrical cavity 45 into the connecting pipe 46 and is transported by the connecting pipe 46 into the serpentine tube 42. The serpentine tube 42 can preheat the coating material in the storage cavity 47. After the heated coating material becomes more fluid, its adhesion is also enhanced, and it can be better bonded to the diaphragm, improving the coating quality. The used steam is transported back to the steam generator 2 through the exhaust pipe 22, facilitating the recovery of the subsequent waste heat.

[0019] In this embodiment, a cylinder 32 is fixedly connected to the top surface of the preheating shell 3. The end of the piston rod of the cylinder 32 is fixedly connected to the moving frame 43; when the cylinder 32 is opened, the piston rod of the cylinder 32 drives the piston rod to move, so that the moving frame 43 moves up and down. After the moving frame 43 moves to contact the diaphragm, the diaphragm can be preheated and flattened.

[0020] Further, a storage box 33 is fixedly connected to the top surface of the preheating shell 3. A feeding pump 34 is fixedly connected to the side wall of the storage box 33. A feeding pipe 35 is fixedly connected and communicated at the discharge port of the feeding pump 34. The feeding pipe 35 is communicated with the storage cavity 47. The storage box 33 stores coating materials. When coating work needs to be carried out, the feeding pump 34 is turned on. The feeding pump 34 transports the coating materials in the storage box 33 into the storage cavity 47 through the feeding pipe 35 and waits for preheating.

[0021] It should be noted that the air inlet pipe 21 movably passes through the side wall of the preheating shell 3, and the serpentine pipe 42 is located outside the storage cavity 47 and is conveyed by the conveyor 1. The air inlet pipe 21 movably passes through the preheating shell 3. When the moving frame 43 moves up and down, the air inlet pipe 21 can also normally convey steam to the rotating roller 44. The serpentine pipe 42 can heat the coating materials inside the storage cavity 47 to improve the adhesion of the coating materials.

[0022] It should also be noted that a plurality of nozzles 48 are fixedly connected and communicated at the bottom of the preheating box 41. The nozzles 48 are communicated with the storage cavity 47. The nozzles 48 are equipped with solenoid valve structures. The solenoid valves on the nozzles 48 can better control the flow rate of the coating materials in the storage cavity 47, which is convenient for better coating work.

[0023] In this embodiment, two openings 31 are opened at the bottom of both sides of the preheating shell 3. The diaphragm enters the preheating shell 3 through the openings 31 for preheating.

[0024] In this embodiment, a coating machine is also disclosed, which includes a fixed block 5 fixedly connected to the side wall of the preheating shell 3, a threaded rod 51 threadedly connected to the fixed block 5, a scraping strip 52 rotatably connected to the bottom end of the threaded rod 51, two cylindrical rods 53 fixedly connected to the top surface of the scraping strip 52, and the cylindrical rods 53 are slidably connected to the fixed block 5. By rotating and adjusting the threaded rod 51, the threaded rod 51 moves up and down on the fixed block 5. The rotation of the threaded rod 51 drives the scraping strip 52 to move up and down, and the cylindrical rods 53 assist the scraping strip 52 to move up and down. The staff adjusts the height of the scraping strip 52 according to the use requirements. After adjustment, the cooperation between the conveyor 1 and the scraping strip 52 can carry out the coating work.
