[0089] Embodiment 2:

[0090] According to the appendix Figure 1-7 as shown,

[0091] The first limiting unit 45 and the second limiting unit 46 are connected to the lifting unit 5. The lifting unit 5 includes:

[0092] The air cylinder 51 is fixedly installed on the base 41. When the second connecting seat 43 is not parallel to the hot pressing plate 31, by adjusting the lifting height of the plurality of air cylinders 51, the second connecting seat 43 is adjusted to ensure that the density board is not affected by floating and to ensure the hot pressing effect;

[0094] The telescopic assembly 53 is located above the fixed seat 52, and the telescopic assembly 53 is fixedly connected to the corresponding first limiting unit 45 or second limiting unit 46.

[0095] The telescopic assembly 53 includes:

[0096] The sleeve 531 is fixedly connected to the fixed seat 52. The sleeve 531 is used to cooperate with the cylinder 51 to push the second connecting seat 43 to move and adjust the position of the density board.

[0097] The fixed column 532 is fixedly installed on the fixed seat 52.

[0098] The connecting rod 533 is slidably connected to the inner wall of the fixed column 532. The top end face of the connecting rod 533 is fixedly connected to the corresponding first limiting seat 451 or second limiting seat 461.

[0099] The spring 534 is sleeved on the outer peripheral wall of the fixed column 532. The two ends of the spring 534 are respectively fixedly connected to the fixed seat 52 and the first limiting seat 451.

[0100] Working principle: When the density board is placed on the second connecting seat 43, the cylinder 51 is started to drive the fixed seat 52 to move. Under the movement of the fixed seat 52, the sleeve 531 is pushed upward until the sleeve 531 contacts the bottom of the second connecting seat 43.

[0101] At this time, the spring 534 is compressed. Under the push of the spring 534, the corresponding first limiting seat 451 and second limiting seat 461 generate an upward thrust. At this time, the first limiting seat 451 and the second limiting seat 461 move upward. At the same time, one end of the density board contacts the first horizontal slope 452 and the second horizontal slope 462. Under the action of gravity, the density board slides until the density board is in the horizontal center position.

[0102] When the density board is at the first longitudinal slope 453 and the second longitudinal slope 463, under the action of gravity, the density board slides until the four corners of the density board are respectively between the first limiting groove 454 and the second limiting groove 464 to adjust the position of the density board.

[0103] At this time, the driving mechanism drives the driving roller 21 to rotate. Under the rotation of the driving roller 21, the driving roller 21 drives the corresponding transmission belt 22 to rotate accordingly. Under the action of the transmission belt 22, a plurality of driving rollers 21 are driven to rotate simultaneously to drive the impregnated paper to be transmitted onto the density board.

[0104] The first limit seat 451 and the second limit seat 461 are used to determine whether the positioning of the impregnated paper and the density board is skewed. At this time, the hydraulic pump 32 is started to push the hot pressing plate 31 to move, so that the hot pressing plate 31 moves downward, and the hot pressing plate 31 is squeezed against the first limit seat 451 and the second limit seat 461, pushing the first limit seat 451 and the second transverse slope 462 to slide along the inner wall of the second connecting seat 43, and pushing the connecting rod 533 to slide along the fixed column 532;

[0105] At this time, the impregnated paper can be pushed to contact and squeeze the density board, avoiding skewing of the impregnated paper and the density board during the lamination of the impregnated paper and the density board, which affects the processing effect. Under the action of the hot pressing plate 31, hot pressing is performed on the impregnated paper and the density board. (The hot pressing plate 31 can be heated to the set temperature by means such as electric heating, heat-conducting oil circulation or steam heating. The system is internally equipped with a temperature-sensing probe to monitor the temperature in real time, and the heating power is adjusted through an electronic control module to ensure stable temperature);

[0106] Pressure is applied to the impregnated paper and the density board through the hot pressing plate 31 to eliminate air bubbles and voids between the materials and promote close bonding at the molecular level. The pressure parameters need to be adjusted according to the material characteristics, and the pressure increase time and the pressure holding time are adjusted according to the actual situation;

[0107] When the hot pressing is completed, the hot pressing plate 31 moves to separate from the impregnated paper and the density board, and then the cylinder 51 drives the second connecting seat 43 to move downward, so that the second connecting seat 43 contacts and squeezes the support frame 42, facilitating the removal of the density board laminated on the second connecting seat 43.

[0108] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments.
