The sheet is moved out from the interior of the cooling buffer box 10, thereby making the process of taking and placing the semi-cured sheet more convenient. During the pressing process of the sheet, the conveying and heating mechanism 5 can achieve the effect of blocking the openings on the left and right ends of the cooling buffer box 10, thereby being able to quickly heat and heat the interior of the cooling buffer box 10, thereby avoiding the situation where the existing sheet is quickly cooled after the pressing is completed, thereby causing it to shrink and deform. By starting the electric hydraulic rod 11 to drive the pressing plate 7 to move downward, the sheet can be pressed under the action of the conveying and heating mechanism 5.

[0029] Four limiting rods 8 are fixedly connected to the upper side of the pressure plate 7. The upper ends of the four limiting rods 8 pass through the upper side wall of the cooling buffer box 10 and are respectively connected to the four L-shaped tooth plates 12. The four L-shaped tooth plates 12 are respectively engaged with the two blocking mechanisms 13 for transmission. The relatively close ends of the two blocking mechanisms 13 are respectively fixedly connected to the front and rear ends of the cooling buffer box 10. The setting of the limiting rods 8 can increase the stability of the pressure plate 7 during movement. The setting of the blocking mechanism 13 and the cooperation of the L-shaped tooth plates 12 can achieve the effect of blocking the heat dissipation holes opened on the cooling buffer box 10 when the plate is pressed, so that the temperature inside the cooling buffer box 10 can be rapidly increased. After the pressing is completed, the blocking mechanism 13 no longer blocks the several heat dissipation holes opened on the cooling buffer box 10, so that the temperature inside the cooling buffer box 10 can gradually drop to room temperature.

[0030] Furthermore, a spring 9 is sleeved on each of the four limiting rods 8, and a plurality of heat dissipation holes are provided at the front and rear ends of the cooling buffer box 10.

The left and right sides of the T-shaped support block 55 are fixedly connected to two fixed cross plates 54, and the relatively far ends of the four fixed cross plates 54 are fixedly connected to the two baffles 52, respectively. The plate 52 is adapted to the cooling buffer box 10 with openings on both ends. A heating plate 53 is provided at the relatively close ends of the two baffles 52. The two baffles 52 are slidably connected to the threaded rod 57 and the two fixing rods 58 through three through holes opened inside the lower ends. The two baffles 52 can seal the openings opened on both ends of the cooling buffer box 10. Then, by starting the two heating plates 53, the temperature inside the cooling buffer box 10 can be rapidly increased. At this time, it effectively avoids the situation where the plate is quickly cooled and shrinks and deforms during the process of being taken out after the pressing is completed. The rotation of the sprocket 4 drives the threaded rod 57 to rotate, and then the placement plate 56 can be driven to move out of the interior of the cooling buffer box 10, thereby driving the plate to move out of the interior of the cooling buffer box 10 after the cooling is completed.

[0032] The two blocking mechanisms 13 each include two gears 137, and the four gears 137 are respectively meshed with the four L-shaped toothed plates 12 for transmission. The four gears 137 are respectively fixedly connected to the two ends of the two worm gears 139, and the two worm gears 139 are movably connected to two support plates 138. The relatively close ends of the four support plates 138 are respectively fixedly connected to the front and rear ends of the cooling buffer box 10, and the two worm gears 139 are respectively meshed with the two worm wheels 1310 for transmission. The two worm wheels 1310 are respectively fixedly connected to one end of the two rotating rods 135, and the other ends of the two rotating rods 135 are respectively fixedly connected to the cams 134. The relatively close ends of the two cams 134 are overlapped with the blocking plates 131, and the two blocking plates 131 are respectively movably connected to the four limiting rods 132 132 through the two limiting holes opened therein.

The two support plates 2 136 are fixedly connected to the cooling buffer box 10. In the process of driving the pressure plate 7 to move downward, the four L-shaped toothed plates 12 can be driven to move downward under the action of the set limiting rod 18. At this time, the two worm gears 139 can be driven to rotate under the action of the set gear 137. The rotation of the two worm gears 139 can drive the two rotating rods 135 to rotate under the action of the set worm gears 1310. The rotation of the two rotating rods 135 can drive the two blocking plates 131 to approach each other under the action of the set cam 134 until they are respectively overlapped at the front and rear ends of the cooling buffer box 10. At this time, the blocking effect of the several heat dissipation holes opened on the cooling buffer box 10 can be achieved, thereby ensuring the sealing of the cooling buffer box 10 inside during the pressing of the plate.

[0033] The working principle of this utility model is:

[0034] When the device is used to press the semi-cured sheet material, the sheet material is first placed on the placement plate 56, and then the motor 2 is started, and then the placement plate 56 is driven to move to the inside of the cooling buffer box 10 under the action of the provided sprocket 1 4, sprocket 2 3, threaded rod 57 and fixed rod 58. In this process, the openings on the left and right ends of the cooling buffer box 10 can be blocked under the action of the provided two baffles 52. Then the electric hydraulic rod 11 is started to drive the pressure plate 7 to move downward. In the process of driving the pressure plate 7 to move downward, the two worms 139 can be driven to rotate under the action of the provided limiting rod 1 8, L-shaped tooth plate 12 and gear 137. Through the rotation of the two worms 139, the two sealing plates 131 can be driven to move closer to each other under the action of the provided worm gear 1310, rotating rod 135 and cam 134, thereby The cooling buffer box 10 is sealed with the heat dissipation holes provided on the cooling buffer box 10. As the pressing plate 7 moves downward, the plate can be pressed together with the cooperation of the placement plate 56. In the process of pressing the plate, the heating plate 53 is started to quickly heat the interior of the cooling buffer box 10 to a certain temperature, thereby buffering the cooling process of the plate after the pressing is completed. In the process of driving the pressing plate 7 to reset after the pressing is completed, the two sealing plates 131 can be driven to reset under the action of the limiting rod 1 8, L-shaped tooth plate 12, gear 137, worm 139, worm wheel 1310, rotating rod 135 and spring 2 133. At this time, the temperature inside the cooling buffer box 10 will gradually decrease through the several heat dissipation holes provided thereon. After it drops to a certain temperature, the pressed plate can be taken out to avoid shrinkage of the plate.
