Description

Technical Field

[0001] This utility model belongs to the technical field of sheet metal lamination machine, and specifically relates to a sheet metal surface lamination machine with heating function. Background Technology

[0002] The surface laminating machine for sheet metal with heating function is a core piece of equipment in furniture manufacturing, building decoration and other fields. It uses electromagnetic heating rollers to heat and pressurize the sheet metal and the veneer material, so that the adhesive can be fully cured and the two can be firmly bonded together. Compared with traditional heat-conducting oil heating rollers, electromagnetic heating rollers have become the mainstream choice for wide sheet metal processing due to their advantages such as built-in coils, low bearing temperature and low failure rate.

[0003] However, to ensure a safe distance between the end cap and the bearing, existing electromagnetic heating rollers typically leave a 40-100mm blank area between the induction coil and the edge of the roller. Even with optimization through magnetic density compensation, the edge temperature of the roller surface is still lower than that of the middle area due to problems such as rapid heat dissipation from the end cap and insufficient compensation, resulting in an ineffective heating edge. This problem is particularly prominent in the processing of wide sheet materials. Due to insufficient temperature at the edge of the sheet material, the adhesive does not cure completely, and edge curling or rolling is prone to occur after bonding. The scrap rate can reach 5%-12%, requiring additional manual rework and repair, which seriously affects production efficiency.

[0004] In summary, existing sheet metal surface laminating machines with heating functions face the technical challenge of insufficient edge temperature of the electromagnetic heating roller, leading to bonding defects. How to accurately direct the recovered residual heat to the edge area of ​​the sheet metal for preheating compensation has become a key technical requirement for improving the bonding quality of wide sheet metal and reducing energy consumption.

[0023] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0024] like Figures 1-4 As shown, a sheet metal surface laminating machine with heating function includes a base plate 1, a mounting frame 2 is mounted on the top of the base plate 1, a movable plate 3 is slidably connected to the bottom of the mounting frame 2, a drive structure is mounted on the mounting frame 2, an electric push rod 7 is mounted on the bottom of the movable plate 3, and an installation frame 8 is fixed vertically downward on the stroke rod of the electric push rod 7. When the sheet metal is placed on the base plate 1, the movable plate 3 is driven to move left and right by the drive structure, which in turn drives the electric push rod 7 and the installation frame 8 to move. The electric push rod 7 is also driven so that the stroke rod of the electric push rod 7 drives the installation frame 8 to move downward.

[0025] A partition 9 is fixed inside the mounting frame 8, dividing the interior of the mounting frame 8 into a first mounting chamber 10 and a second mounting chamber 11. The first mounting chamber 10 and the second mounting chamber 11 are respectively located on one side and the other side of the partition 9. An electromagnetic heating roller 12 is installed inside the first mounting chamber 10. When the mounting frame 8 moves down, it can drive the electromagnetic heating roller 12 to move and stick to the plate on the base plate 1, thereby heating the plate through the electromagnetic heating roller 12. A pressing structure is installed inside the second mounting chamber 11, and the plate and the film, wood grain paper, metal sheet and other materials pressed on the plate are pressed together by the pressing structure. The user can also use other methods, such as hydraulic cylinders, to press it. A conveyor belt can be set on the base plate 1 to transport the plate.

[0026] See attached document Figure 2 The drive structure includes a threaded rod 4 and a limiting rod 5 installed inside the mounting frame 2. The threaded rod 4 is rotatably connected to the mounting frame 2, the limiting rod 5 is fixedly connected to the mounting frame 2, the threaded rod 4 is threadedly connected to the moving plate 3, and the limiting rod 5 is slidably connected to the moving plate 3. A motor 6 is installed at one end of the mounting frame 2, and the output end of the motor 6 passes through the mounting frame 2 and is connected to one end of the threaded rod 4.

[0027] When the motor 6 is driven, it can drive the threaded rod 4 to rotate, and through the threaded connection between the threaded rod 4 and the moving plate 3, and through the sliding connection between the moving plate 3 and the limiting rod 5, the moving plate 3 can move left and right at the bottom of the mounting frame 2, thereby driving the electric push rod 7 and the mounting frame 8 to move, so that the electromagnetic heating roller 12 in the mounting frame 8 can move.

[0028] A heat-conducting structure is installed on the mounting frame 8, and the heat-conducting structure is connected to the inside of the first mounting chamber 10;

[0029] See attached document Figure 4 The heat-conducting structure includes a connecting pipe 16, which is inserted into the first mounting chamber 10. A heat-conducting pipe 17 is installed at the end of the connecting pipe 16 away from the mounting frame 8, and both ends of the heat-conducting pipe 17 extend to the two sides of the top of the base plate 1. When the electromagnetic heating roller 12 heats up, it can not only heat the plate below, but also heat the internal space of the first mounting chamber 10. At this time, the heat is conducted to the heat-conducting pipe 17 through the connecting pipe 16. The electromagnetic heating roller 12 can conduct heat to both ends of the top of the base plate 1, that is, to the two ends of the electromagnetic heating roller 12, so that the heat can be dissipated from both ends of the heat-conducting pipe 17, thereby heating both sides of the plate and reducing the phenomenon of curling of the film, wood grain paper, metal sheet and other materials pressed on the plate due to insufficient heating of the two sides of the plate by the electromagnetic heating roller 12.

[0030] A fan 18 is installed inside the connecting pipe 16. The fan 18 can quickly draw the heat inside the first installation chamber 10 into the connecting pipe 16 and quickly transfer it to the heat conduction pipe 17 through the connecting pipe 16. The heat conduction pipe 17 can then quickly transfer the heat to both sides of the plate.

[0031] See attached document Figure 4 A first inclined surface 19 is provided on the inner wall of the first installation chamber 10 and at the bottom of the connecting pipe 16. A second inclined surface 20 is provided on the inner wall of the first installation chamber 10 and at a position symmetrical to the first inclined surface 19. The first inclined surface 19 and the second inclined surface 20 enable the first inclined surface 19 to quickly rise and guide the heat into the connecting pipe 16, and the second inclined surface 20 enable the second inclined surface 20 to guide the heat to a position close to the connecting pipe 16.

[0032] See attached document Figures 3-4 The pressing structure includes at least one pressure roller 13, which is disposed inside the second mounting chamber 11. Sliding blocks 14 are rotatably connected to both ends of the pressure roller 13. The two sliding blocks 14 are respectively assembled at both ends of the inner wall of the second mounting chamber 11. Through the setting of the pressure roller 13, the pressure roller 13 can press the heated board and the film, wood grain paper, metal sheet and other materials on the board, thereby squeezing out and removing air bubbles in the gaps between the board and the materials. The sliding blocks 14 are slidably connected to both ends of the inner wall of the second mounting chamber 11. A spring 15 is fixed to the top of the sliding block 14 and is fixedly connected to the top of the second mounting chamber 11. Through the setting of the spring 15, the spring 15 can continuously press the sliding block 14 down, and the sliding block 14 drives the pressure roller 13 to continuously exert stronger pressure on the board and materials, thereby making it easier to expel air bubbles.

[0033] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
