Description

Technical Field

[0001] This utility model relates to the field of insulation board coating, and more specifically, to a pressure plate coating mechanism for insulation board production. Background Technology

[0002] Polyurethane insulation material is a high-performance synthetic material with advantages such as high specific strength and low thermal conductivity. It is mainly used as a thermal insulation material, and secondarily as a structural material. Polyurethane insulation material is often used to make exterior wall insulation boards to meet the thermal insulation requirements of buildings. In the production process of insulation boards, an aluminum film is covered on a color steel plate sprayed with polyurethane material, so that after the polyurethane foams, it covers the surface of the polyurethane layer, thus serving as the inner side of the insulation board.

[0003] The utility model patent with authorization announcement number CN216914827U belongs to the technical field of pigsty equipment processing. Specifically, it discloses a film coating device for insulation boards, including a heating box set above a roller conveyor. The heating box has a channel that runs through it and extends along the conveying direction of the roller conveyor. The outlet of the channel is connected to a film coating mechanism. The heating box is equipped with a temperature sensor and a heat generation unit. The temperature sensor is electrically connected to the heat generation unit through a controller. Heat conduction holes are evenly distributed on the side of the heating box facing the roller conveyor. The heating box is also connected to a blower. This device preheats the aluminum film and heats the polyurethane sprayed on the color steel plate, keeping the polyurethane at a suitable temperature. This is conducive to the rapid foaming of polyurethane and ensures that the residual heat of the aluminum film can be used to promote the continued foaming of polyurethane after it comes into contact with the aluminum film, so as to ensure that the polyurethane fully contacts the aluminum film and eliminates hollow defects.

[0004] In the aforementioned publicly available results, the protective film is preheated by an external heating box before being pressed and coated. This method is prone to cooling during transport, which can affect the stability of the coating and makes it difficult to accurately control the temperature. The lack of a hollow coating roller for directly mounting the heating rod also makes it impossible to directly press and coat the film at the preheating position. This results in poor adaptability, insufficient stability, and is also not conducive to separate installation and maintenance. These methods need to be improved. Utility Model Content

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a pressing and film-coating mechanism for the production of insulation boards. The insulation board and protective film are fed by conveying rollers on the frame. The hollow shaft and hollow film-coating roller are mounted on the second bracket, which can be combined and aligned for pressing and film-coating. Furthermore, the support rod and heating rod are hinged and mounted through the internal mounting tube, which can be combined and positioned.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1 , Figure 3 and Figure 5A pressure plate coating mechanism for producing insulation boards includes a frame 1. A support roller 11 is rotatably mounted on one end of the frame 1. First supports 12 are provided on both sides of the frame 1. Conveyor rollers 13 are rotatably mounted on both ends of the first supports 12. Insulation boards 14 are slidably connected to the surface of the conveyor rollers 13, allowing for combined installation and conveying, facilitating continuous coating processing, and ensuring high efficiency and stability. A protective film 15 is fixedly connected to the surface of the insulation board 14. Second supports 16 are fixedly connected to both sides of the other end of the frame 1. A hollow shaft 17 is rotatably mounted on one end of the second support 16. One end is connected to a special pipe 2, while the other end can be connected to a motor for driving, facilitating rotation adjustment for uniform heating, and rotating to press the protective film 15, allowing for hot-pressing lamination onto the insulation board 14, which is beneficial for coating processing and positioning. One end of the hollow shaft 17 is fixed. A hollow coating roller 18 is connected, and an installation tube 2 is inserted into the center of the hollow coating roller 18. A hinge seat 21 is fixedly connected to the side of the installation tube 2. A support rod 22 is hinged to one end of the hinge seat 21, and a heating rod 23 is hinged to one end of the support rod 22. A pressing spring 24 is fixedly connected to one side of the support rod 22 and is pressed against the outer surface of the installation tube 2. The heating rods 23 are evenly distributed at equal angles inside the hollow coating roller 18. Through the internal installation of the heating rods 23, electricity can be applied to heat the hollow coating roller 18. After the hollow coating roller 18 is heated, the heat is transferred to the surface, which can preheat the protective film 15 in contact. Combined with the extrusion and conveying of the roller below, it can directly perform pressing, lamination and positioning, which is convenient and efficient. Lamination is performed directly at the heating position, reducing heat loss, improving lamination stability, and facilitating installation and use.

[0027] Please see Figure 2 and Figure 4 The surface of the mounting tube 2 is provided with a through hole 25. A pull rope 26 is slidably connected inside the through hole 25. One end of the pull rope 26 is fixedly connected to one side of the heating rod 23, and a connecting ring 27 is fixedly connected to the other end of the pull rope 26. The connecting ring 27 is located at the end of the mounting tube 2. The pull rope 26 is slidably connected inside the mounting tube 2. By installing the pull rope through the through hole and connecting it with the connecting ring at the end, it can be pulled and adjusted uniformly, thereby pulling the heating rod to retract, avoiding interference, facilitating installation and disassembly, and making it highly adaptable. By tightening the pull rope 26 through the connecting ring 27, the heating rod 23 can be retracted. At the same time, the support rod 22 is hinged and flipped, compressing the top spring 24, which can reduce the opening gap, thereby retracting to the inside of the support ring 31, avoiding interference, and can be pulled out from inside the hollow shaft 17 for easy disassembly and cleaning, or partial replacement for maintenance, making it highly adaptable.

[0028] Please see Figure 3 and Figure 4One end of the mounting tube 2 is fixedly connected to a mounting bracket 3, which is fixedly connected to one side surface of the second bracket 16. The other end of the mounting tube 2 is fixedly connected to a support ring 31, which is rotatably connected to the inside of the hollow shaft 17. The surface of the support ring 31 is provided with a vent hole 32, which is located at one end inside the hollow shaft 17. By connecting the mounting bracket through the mounting tube and combining it with the support ring, the tube can be assembled and positioned to avoid interference with the rotation of the film coating, ensuring safety and stability, and facilitating adjustment and use. In use, the support ring 31 can be inserted into the hollow shaft 17 to assist in supporting the mounting tube 2. The vent hole 32 allows air to pass through, preventing internal heating and pressure expansion, thus improving safety. The mounting bracket 3 is installed on the second bracket 16 with screws to assist in positioning the mounting tube 2. It can be suspended and positioned inside the hollow shaft 17 and the hollow film coating roller 18 to avoid interference with rotation and facilitate heating and use.
