When the turntable 21 is in a hot-pressing state, one upper partition plate 13 corresponds to one lower partition plate 22, and the connection part is sealed in a sliding manner, so as to separate the spaces of the feeding area 10a, the hot-pressing area 10b, the cooling area 10c and the discharging area 10 d. The hot-pressing area 10b is positioned in the closed space, so that heat loss after hot pressing in the hot-pressing area 10b is reduced, influence on the external environment is reduced, and the energy-saving and environment-friendly support is met.

Because the hot pressing plate 62 and the hot pressing process are both performed within the range of the hot pressing area 10b, the raw material 100 in the hot pressing box 31 is hot pressed and molded by the hot pressing plate 62 to obtain the plate 200, and then the plate 200 is transported to the range of the cooling area 10c to be independently cooled, so that the mutual interference of environments among the areas is avoided, the hot pressing plate 62 does not need to be discharged after being completely cooled, the loss of heat energy is reduced, and the waiting time in the production process is saved.

Referring to fig. 3, 6 and 7 in combination, the mounting shell 1 further includes an arc-shaped cover 14, the arc-shaped cover 14 is fixedly arranged on the support tube 12, and the arc-shaped cover 14 is blocked at the top of three connection plates 34.

In this embodiment, one of the connecting plates 34 located in the discharging area 10d is not in contact with the arc-shaped cover 14, and the other three connecting plates 34 are blocked and limited by the arc-shaped cover 14.

The stability of the hot pressing box 31 when not discharging is improved, the material returning plate 32 is prevented from shaking in the adjusting and transferring process, and the quality of hot pressing forming is ensured.

Referring to fig. 2, 3 and 11 in combination, the rotating mechanism 2 further includes a correcting device 23, the correcting device 23 includes a fixing rod 231 and a docking cover 232, the top end of the fixing rod 231 is fixed to the turntable 21, the bottom end of the fixing rod 231 is fixed to the docking cover 232, a guiding chute 233 is formed in the docking cover 232, and one guiding chute 233 is disposed towards the T-shaped rod 77.

When the rotation angle of the turntable 21 is slightly deviated, the T-shaped rod 77 can automatically correct the position of the turntable 21 after passing through the guide chute 233, so as to adaptively align the hot press box 31 with the hot press plate 62.

Because the hot pressing box 31 on the turntable 21 needs to ensure that the hot pressing box 31 and the hot pressing plate 62 are in an aligned state before hot pressing, if the hot pressing plate 62 and the hot pressing box 31 cannot be normally abutted due to slight deviation, the turntable 21 after station switching needs to be corrected.

Before the hot pressing plate 62 moves down and is in butt joint with the hot pressing box 31 for hot pressing, the T-shaped rod 77 moves up and drives the material returning plate 32 to automatically return the formed plate 200, the T-shaped rod 77 passes through the guide chute 233 and pushes the butt joint cover 232 in a slightly offset state to rotate, the butt joint cover 232 drives the turntable 21 to rotate through the fixing rod 231, and the turntable 21 drives the hot pressing box 31 to rotate for correction, so that the hot pressing box 31 in the hot pressing area 10b and the hot pressing plate 62 are automatically aligned in the hot pressing process.

In this embodiment, the material returning plate 32 moves upwards to push the molded and cooled polyester fiber board to leave the hot pressing box 31.

The transfer equipment and the mechanical arm can be provided, the polyester fiber board is transferred to the upper part of the conveying equipment through the mechanical arm, and the polyester fiber board is transferred to the next procedure through the conveying equipment, so that the subsequent treatment of the polyester fiber board after hot press molding is facilitated.
