[0022] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0023] Reference Figure 1-5 The utility model embodiment is an energy-saving plywood hot pressing device, which includes a base 1, a fixing frame 2 and a box body 3 are fixedly connected to the top of the base 1, the box body 3 is covered on the outside of the fixing frame 2, two box doors 10 are symmetrically hinged on the front side of the box body 3, a heater 11 is arranged on the inner wall of the rear side of the box body 3, a plurality of guide grooves 5 are symmetrically and equidistantly provided inside the fixing frame 2, a slide plate 6 is slidably connected inside the plurality of guide grooves 5, a placement plate 4 is fixedly connected between every two relative slide plates 6, the plurality of placement plates 4 are all set to a structure with openings at both ends and a hollow interior, and a plurality of through holes 9 are provided inside the plurality of placement plates 4, and a driving component for pushing the placement plates 4 to move upward is arranged at the bottom of the base 1;

[0024] The plywood to be hot-pressed is placed on the placement plate 4, and the box door 10 is closed so that the box body 3 is in a closed state. The interior of the box body 3 can be heated and heated under the action of the heater 11, so that the plywood can be heated to the required temperature. The hollow structure of the placement plate 4 and the provided through holes 9 can make the heat flow inside the box body 3 smoother, so that the uniformity of heating multiple plywood can be improved. After the plywood is heated, the bottom placement plate 4 can be pushed upward by the driving component. The placement plate 4 moving upward drives the slide plate 6 to slide inside the guide groove 5 to ensure the stability of the placement plate 4. The plywood hot pressing work can be completed by squeezing the plywood and the placement plate 4 together through the moving placement plate 4. The operation is simple and multiple plywood can be hot-pressed synchronously, which has higher production efficiency.

[0025] The driving assembly includes four hydraulic cylinders 7 equidistantly and symmetrically fixedly connected to the bottom of the base 1 and a pressure plate 8 movably connected to the top of the base 1 and located below the placement plate 4. The tops of the piston rods of the four hydraulic cylinders 7 all penetrate the interior of the base 1 and are fixedly connected to the bottom of the pressure plate 8. After the operation of the hydraulic cylinders 7 drives the pressure plate 8 to move upward and fit the bottom of the placement plate 4, the continuous operation of the hydraulic cylinders 7 can better drive the placement plate 4 and the plywood to fit each other to complete the hot pressing work.

[0026] A temperature sensor 12 is provided on the inner wall of the box body 3 , and the temperature sensor 12 can well monitor the temperature inside the box body 3 , so as to control the operating state of the heater 11 according to the temperature inside the box body 3 .

[0027] The multiple placement boards 4 are all made of aluminum material. The placement boards 4 made of aluminum have better thermal conductivity, which is conducive to increasing the temperature of the placement boards 4 after the placement boards 4 absorb heat, so as to better heat the plywood.

[0028] The bottom of the base 1 is configured as an L-shaped structure. The base 1 increases the contact area with the ground through the L-shaped structure, and can stably support the fixing frame 2.

[0029] The two doors 10 are fixedly connected to a handle on one side away from the hinge, which makes the door 10 easier and more convenient to open and close. The temperature sensor 12, the four hydraulic cylinders 7 and the heater 11 are all electrically connected to the external control device, and the operating state of the hydraulic cylinder 7 and the heater 11 can be easily controlled by the external control device according to the monitoring temperature of the temperature sensor 12.

[0030] Working principle: Place the plywood to be hot-pressed on the placement plate 4, close the box door 10 to make the box body 3 in a closed state, and heat the inside of the box body 3 under the action of the heater 11, so that the plywood can be heated to the required temperature, and the hollow structure of the placement plate 4 and the set through holes 9 can make the heat flow inside the box body 3 smoother, thereby improving the uniformity of heating multiple plywood sheets;

[0031] After the plywood is heated, the hydraulic cylinder 7 drives the pressing plate 8 to move upward and fit with the bottom of the placement plate 4. Under the continuous operation of the hydraulic cylinder 7, the placement plate 4 and the plywood can be better driven to fit each other to complete the hot pressing work. The operation is simple and multiple plywood can be hot pressed synchronously, which has higher production efficiency.

[0032] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
