First, connect the gas pipe 7 to the gas transmission equipment, then put the two wooden boards coated with glue into the box 1, then control the vacuum pump 3 to extract the gas in the box 1 to keep the box 1 in a vacuum state, and then control the electric The push rod 4 pushes the lifting frame 5 to move downward with the pressure air bag 6 and the clamp 82, so that the bottom of the pressure air bag 6 fits on the upper wooden board, and the bottom of the clamp rod 825 on the clamp 82 is in contact with the inner bottom of the box 1 When the bottom of the clamping rod 825 is in contact with the inner bottom of the box 1, the clamping rod 825 cannot continue to move downward, so the movable block 823 continues to move downward to stretch the tension spring 826, which can be applied to plates of different thicknesses. Lamination. The lifting frame 5 moves downward and drives the connecting plate 86, the lower pressure plate 89 and the frame rod 810 to move downward. The connecting plate 86 moves downward and pushes the L-shaped push rod 87 downward through the compression spring B88. When the L-shaped push rod 87 moves downward to the position After the block 85 contacts, the L-shaped push rod 87 cannot continue to move downward, so the connecting plate 86 continues to move downward to compress the compression spring B88. The L-shaped push rod 87 cannot move downward and the lower pressure plate 89 continues to move downward, so that the rear of the lower pressure plate 89 The front part of the lower pressure plate 89 swings downward to push the frame rod 810 to move downward on the lifting frame 5, and the return rod on the frame rod 810 moves downward to push the four The inclined rods 822 are close to each other, so that the four U-shaped sleeve rods 821 can drive the four movable blocks 823 to be close to each other, so that the four clamping rods 825 are close to each other to correct the upper and lower plates so that the upper and lower plates are aligned centrally. When the upper and lower plates are aligned in the center, the four clamping rods 825 are in close contact with the plates and cannot continue to approach each other, and the four movable blocks 823 cannot continue to approach each other, so the four U-shaped sleeve rods 821 continue to approach each other to compress the buffer springs 824. In this way, plates of different sizes can be limited, so that the upper and lower plates can be effectively limited through the four clamping rods 825 to avoid displacement and misalignment of the plates during the pressure process, thereby avoiding damage to the plates, and can Improving the quality of finished plate products can increase the pass rate of plate lamination. When the upper and lower plates are limited by the clamping rod 825, the gas transmission equipment will input high-temperature and high-pressure gas into the pressure airbag 6 through the gas transmission pipe 7, so that the pressure airbag 6 expands and exerts pressure on the plates to complete the pressing of the plates. And the expansion of the pressure air bag 6 to press the plates can make the pressure more uniform, thereby improving the lamination effect of the plates, and the high-temperature and high-pressure gas can provide enough pressure and heat to make the plates closely fit together and make the glue completely Curing, thereby further improving the lamination effect of the panels.

The cross-shaped guide rod 81, clamp 82, connecting plate 86, lower pressure plate 89 and frame rod 810 are driven to move upward. Since the compression spring B88 is compressed, the L-shaped push rod 87 will not immediately follow the connecting plate 86 and the lower pressure plate 89. Move upward, thereby causing the lower pressure plate 89 to move upward and disengage from the L-shaped push rod 87. Under the reset action of the compression spring A83, the four clamps 82 are moved away from each other, and the inclined rods 822 on the clamps 82 are moved away from each other to push the The return-shaped rod moves upward, so that the entire frame rod 810 moves upward on the lifting frame 5. The frame rod 810 moves upward on the lifting frame 5 and pushes the lower pressure plate 89 to swing upward to a horizontal state, so that the lower pressure plate 89 reconnects with the L-shaped push plate. The rod 87 contacts, and when the compression spring B88 returns to its original state, the connecting plate 86 continues to move upward and pulls the L-shaped push rod 87 through the compression spring B88 to move upward and reset.

Since this device uses high-temperature and high-pressure gas to pressurize and heat the plates, so that the plates fit closely together and the glue is completely solidified, the temperature inside the box 1 is relatively high, so the worker can put his hand into the box 1 to perform It is easy to be burned when taking out materials. Please refer to Figure 2 and Figure 7. In some preferred embodiments, in order to avoid the problem of workers' hands being burned, a discharging mechanism is also included. The discharging mechanism is provided in the box 1. The discharging mechanism includes two guide rails 91 symmetrically connected to the bottom of the box 1.

Controlling the rotation of the belt transport assembly 94 can cause the pull rod 95 to drive the push plate 92 to move forward to push the pressed plate forward. Controlling the reverse rotation of the belt transport assembly 94 can cause the pull rod 95 to drive the push plate 92 to move backward. Reset, so that the unloading of the plate can be automatically completed, so that there is no need for workers to extend their hands into the box 1 to take out the materials, and thus the hands can be avoided from being burned.

When loading and unloading the board, the board is not supported and suspended in the air. The suspended board can easily cause the center of gravity of the board to deform, causing difficulty in loading and unloading and causing problems such as board deformation.

When the push plate 92 moves forward to push out the pressed plate, The support plate 101 is pulled forward by the pull rope 104 and the push plate 105 is moved forward from the box 1. The compression spring C102 is compressed accordingly, and the support plate 101 is moved out of the box 1 to support the pressed plates. , and after the pushing plate 105 is moved out of the box 1, the pushing plate 105 can be driven to rotate upward to a vertical state under the reset action of the torsion spring 106. After the pressed plate is pushed out, remove the pressed plate from the support plate 101 and reposition the plate that needs to be pressed. When the push plate 92 moves backward to reset, relax the pull rope 104 and compress the spring. Under the reset effect of C102, the support plate 101 drives the push plate 105 to move backward into the box 1.
