[0002] Plywood is a three-layer or multi-layer board material made by peeling wood segments into veneers or planing wood blocks into thin wood, and then gluing them with adhesive. It is usually made of an odd number of veneers, and the fibers of adjacent veneers are glued perpendicular to each other. It is one of the commonly used materials for furniture and one of the three major artificial boards. It can also be used for airplanes, ships, trains, cars, buildings and packaging boxes. A group of veneers are usually assembled and glued in such a way that the grain directions of adjacent layers are perpendicular to each other. Usually, the surface board and the inner board are symmetrically arranged on both sides of the center layer or the core of the board. The veneers coated with glue are staggered in the direction of the grain to form a blank, which is pressed under heating conditions.

[0027] Example:

[0028] Reference Figure 1-Figure 4 A plywood hot press with a lateral pressing function includes a base 1, a support frame 101 is fixedly connected to the base 1, a support plate 102 is arranged on the top of the support frame 101, and two groups of symmetrical hydraulic cylinders 103 are arranged on the support plate 102, and a hot pressing plate 2 is fixedly connected to the output end of the hydraulic cylinder 103 through a connecting rod 301, an electric heater 201 is arranged on the hot pressing plate 2, and an upper pressing block 3 is fixedly connected to the bottom of the hot pressing plate 2. The heat energy is generated by electric energy, and the hot pressing plate 2 is heated by converting the electric energy into heat energy, thereby achieving a heating effect.

[0029] In addition, a supporting platform 401 is fixedly connected to the base 1, and a lower pressing block 4 is fixedly connected to the supporting platform 401, and the upper pressing block 3 cooperates with the lower pressing block 4, so that the plywood can be placed on the surface of the lower pressing block 4, and the glue is filled on the plywood, and then another plywood is placed on the glue, and then subsequent processing is carried out. An electric heater 201 is also arranged in the supporting platform 401 for electrically heating the lower pressing block 4.

[0030] In addition, a guide cylinder 5 is fixedly connected to the base 1, and a guide rod is slidably connected to the guide cylinder 5. A piston is provided at one end of the guide rod, and the piston fits against the inner wall of the guide cylinder 5.

[0031] Here, start the switch of the hydraulic cylinder 103, so that the connecting rod 301 on the hydraulic cylinder 103 drives the hot pressing plate 2 to move. At this time, the upper pressing block 3 at the bottom of the hot pressing plate 2 will move toward the lower pressing block 4, and the upper pressing block 3 will press the plywood on the surface of the lower pressing block 4. At this time, drive the switch of the electric heater 201 to solidify the glue and shape it at the same time.

[0032] It needs to be explained that a boost cylinder 8 is fixedly connected to the base 1, and a boost rod 801 is slidably connected to the boost cylinder 8. A sealing plug is provided at one end of the boost rod 801, and the sealing plug fits against the inner wall of the boost cylinder 8. The other end of the boost rod 801 extends to the outside of the boost cylinder 8 and is fixedly connected to a pressure plate.

The guide cylinder 5 is connected to the boost cylinder 8 through a pipeline, and the boost cylinder 8 is filled with hydraulic oil.

[0033] When the hot pressing plate 2 moves toward the lower pressing block 4, the bottom of the hot pressing plate 2 will be against the pressing plate at the top of the boosting rod 801, and then in the process of the hot pressing plate 2 descending, the boosting rod 801 will drive the sealing plug to move and press the hydraulic oil in the boosting cylinder 8. At this time, the spring 802 is compressed, and the hydraulic oil will be transported to the guide cylinder 5 through the pipeline. At this time, the guide rod in the guide cylinder 5 will drive the limit seat 501 to move upward, and the limit seat 501 is set on the side wall of the lower pressing block 4. At this time, the contact surface of the limit plate 7 will fit with the gap between the upper pressing block 3 and the lower pressing block 4, and the top of the limit seat 501 can be stuck in the clamping plate 202 for limiting.

[0034] At this time, the switch of the electric telescopic rod 6 is started, and the limit plate 7 will move toward the gap between the upper pressing block 3 and the lower pressing block 4, thereby pressing one side of the plywood, and the position of the limit seat 501 can be firmly limited by the locking plate 202, thereby ensuring the stable operation of the electric telescopic rod 6.

[0035] At the same time, the limiting plate 7 can limit and fit one side of the plywood, thereby preventing the two sides of the plywood from deforming and opening outward during hot pressing, preventing the two sides of the plywood from shifting, pressing the two sides of the plywood, and improving the quality of hot pressing of the plywood.

[0036] After the plywood is hot-pressed and formed, the hydraulic cylinder 103 will drive the hot-pressing plate 2 to reset. At this time, the spring 802 in the booster cylinder 8 is reset, so that the limit seat 501 is moved out of the clamping plate 202.
