[0002] Cardboard, also known as board paper, is a thick paper sheet made by processing various pulp and composed of interwoven fibers. The difference between cardboard and paper is usually distinguished by basis weight and thickness. Composite cardboard is a cardboard with a certain thickness formed by hot pressing and laminating multiple single-layer cardboards with glue.

[0003] In the document with the application number CN201720524473.0, the cardboard to be hot-pressed and laminated is placed between the upper plate and the bottom plate. The bottom plate moves upward, and the upper plate moves downward to perform hot pressing on the cardboard. After hot pressing, the upper plate moves upward, and the bottom plate moves downward to take out the hot-pressed cardboard. Then, the cardboard to be hot-pressed is placed again. Each time hot pressing is performed, it is necessary to take out the hot-pressed cardboard, which takes a certain amount of time. Therefore, when hot-pressing and laminating multiple composite cardboards, the hot-pressing speed of the composite cardboard is reduced. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the defect that each time hot pressing is performed, it is necessary to take out the hot-pressed cardboard, which takes a certain amount of time and reduces the hot-pressing speed of the composite cardboard in the prior art, and to propose a hot pressing and laminating device for composite cardboard.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0021] Embodiment 1: Refer to Figures 1-4 , a composite cardboard hot pressing and laminating device, including a housing 1. An inlet is provided on one side of the housing 1, and an outlet is provided on the other side of the housing 1. A first hot pressing mechanism 2 is fixedly connected to the bottom end inside the housing 1. A support table 3 is fixedly connected to the bottom end inside the housing 1. A mounting plate 4 is fixedly connected to the upper end of the housing 1. An electric telescopic rod 5 is fixedly connected to the mounting plate 4. The telescopic end of the electric telescopic rod 5 is fixedly connected to a connecting rod. One end of the connecting rod extends into the housing 1 and is fixedly connected to a second hot pressing mechanism 6. The second hot pressing mechanism 6 is located directly above the first hot pressing mechanism 2;

[0022] The second hot pressing mechanism 6 includes a fixing frame 61. The fixing frame 61 is fixedly connected to the connecting rod. The fixing frame 61 is a heat-insulating frame. A guide plate 7 is fixedly connected to the upper end of the fixing frame 61. The guide plate 7 passes through the housing 1. A hot pressing roller 62 is rotatably connected to the fixing frame 61. A through hole 63 is provided on the hot pressing roller 62, and a heating tube 64 is inserted into the through hole 63.

[0023] Working process: Stack the cardboard that needs to be hot pressed and laminated together. One side of the cardboard passes through the inlet and enters the housing 1. The lower surface of the cardboard contacts the first hot pressing mechanism 2. At the same time, according to the thickness of the cardboard, after the electric telescopic rod 5 is started, it drives the connecting rod to move downward by a set distance. The connecting rod drives the fixing frame 61 to move downward, and the fixing frame 61 drives the hot pressing roller 62 to move downward. The hot pressing roller 62 moves downward by a set distance to squeeze the upper end surface of the cardboard;

[0024] After the first hot pressing mechanism 2 is powered on, it heats up. At the same time, the heating tube 64 is powered on and started. After the heating tube 64 is started, it heats up the hot pressing roller 62. During the movement of the cardboard, the hot pressing roller 62 makes rolling contact with the upper surface of the cardboard, and the first hot pressing mechanism 2 makes rolling contact with the lower surface of the cardboard to hot press and laminate the stacked cardboard. When hot pressing and laminating the cardboard, the cardboard is in a moving state. Continuously introduce the cardboard that needs to be hot pressed from the inlet. After hot pressing, the lower surface of the cardboard contacts the upper surface of the support table 3 and is released from the outlet. There is no need to separately take out the hot-pressed cardboard, and the cardboard can be continuously hot pressed and laminated, thereby improving the speed of cardboard hot pressing.

[0025] Embodiment 2: In Embodiment 1, when introducing the stacked cardboard from the inlet, relative sliding is likely to occur between the stacked cardboard, resulting in misalignment between the cardboard. Refer to Figure 2, as another preferred embodiment of the present utility model, the difference from Embodiment 1 is that a limiting mechanism 8 for limiting the cardboard is connected to the housing 1. The limiting mechanism 8 includes two symmetrically arranged mounting blocks 81, and the two symmetrically arranged mounting blocks 81 are fixedly connected to the housing 1. A bidirectional screw 82 is rotatably connected between the two symmetrically arranged mounting blocks 81. Two parallel moving blocks 83 are slidably connected to the housing 1. A threaded hole is provided on each moving block 83, and the threaded hole is matched with the bidirectional screw 82. A rotating roller 84 is rotatably connected to the bottom end of each moving block 83. An elastic sleeve is sleeved on each rotating roller 84, and the elastic sleeve is a rubber sleeve. Rotate the bidirectional screw 82. After the bidirectional screw 82 rotates, the two moving blocks 83 move towards each other. The two moving blocks 83 drive the rotating rollers 84 to move. Stop rotating the bidirectional screw 82 after the two rotating rollers 84 contact the side of the cardboard. During the movement of the cardboard, the two rotating rollers 84 limit the two sides of the cardboard, so that there is no relative sliding between the stacked cardboard, and the cardboard will not be misaligned.

[0026] The above is only the preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent replacements or changes, and should be covered within the protection scope of the present utility model.
