When the door panels to be hot-pressed are placed on the top surfaces of the hot-pressing plates 3, each transverse motor 902 drives the corresponding transverse screw 904 to rotate, so that the adjacent transverse sliding frames 901 approach each other, each connecting shaft 604 slides in the corresponding transmission groove 903 and approaches each other, each adjacent connecting rod 603 also swings around the corresponding connecting shaft 604 and the hinge point, the angle between each adjacent connecting rod 603 is reduced, each group of rollers 701 descends, and then the corresponding blocking cover 8 blocks the corresponding notch 702 until the hot-pressing top plate 2 and each hot-pressing plate 3 are closed, and each door panel is clamped between the hot-pressing top plate 2 and each hot-pressing plate 3, the hot-pressing top plate 2 and each hot-pressing plate 3 generate heat, and the door panels are hot-pressed;

[0079] After completing the hot pressing operation on the door panel, each transverse motor 902 starts operating, each adjacent transverse sliding frame 901 moves away from each other, each connecting shaft 604 in the same transmission groove 903 moves away from each other, the angle between adjacent connecting rods 603 increases, the hot pressing top plate 2 and each hot pressing plate 3 separate from each other, and at the same time, each sealing cover 8 is disengaged from the slot 702, and then each group of rollers rises to lift up the door panel that has completed hot pressing on the corresponding hot pressing plate 3, and the discharging device 5 starts operating to move the door panel that has completed hot pressing out.

[0080] Embodiment 2:

[0081] like Figure 1 As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, the feeding device 4 and the discharging device 5 both include a lifting shell 4501, which can be lifted and installed at the front end or the rear end of the frame 1; a plurality of rollers 4502, which can be rotatably installed in the lifting shell 4501; a lifting screw 4503, which is driven by a lifting motor 4504 and is connected to the lifting shell 4501 through a screw hole; a feed / discharge motor 4505, which is used to drive one of the rollers 4502 to rotate.

[0083] In this embodiment of the present application, due to the adoption of the above-mentioned structure, during the loading operation, the door panel to be hot-pressed is placed on the rollers 4502 in the lifting shell 4501, and the lifting motor 4504 is operated, so that the lifting screw 4503 drives the lifting shell 4501 to rise and fall to a suitable height, and then the feed / discharge motor 4505 is operated, and the corresponding rollers 4502 rotate to send the door panel to be hot-pressed to the hot pressing plate 3 at the corresponding height. As the door panel moves onto the hot pressing plate 3, the front end pushes the push plate 405 toward the hot pressing plate 3, so that the push plate 405 swings around the hinge point between it and the connecting plate 403 until the outer end of the door panel moves to the push plate 405. Between the shift plate 405 and the hot pressing plate 3, at this time, the door panel can rotate the roller 4502, and the push plate 405 returns to a vertical state under the action of gravity, and its lower end height is lower than the upper surface of the door panel. Then the pushing cylinder 402 runs, the pushing piston 404 extends, the connecting plate 403 and the push plate 405 approach the hot pressing plate 3, and the push plate 405 contacts the outer end of the door panel to push the door panel to the top of the hot pressing plate 3. Then the pushing cylinder 402 resets, the pushing piston 404, the connecting plate 403 and the push plate 405 retract, the lifting motor 4504 runs, and the lifting screw 4503 drives the lifting shell 4501 to drop to the initial position, which is convenient for loading.

[0084] During unloading, the lifting motor 4504 and the lifting motor 4504 operate synchronously, so that the lifting shell 4501 and the lifting shell 4501 are lifted to the same height, and then the pushing cylinder 402 operates, the pushing piston 404 extends, the connecting plate 403 and the pushing plate 405 approach the hot pressing plate 3, and the pushing plate 405 contacts the outer end of the door panel, pushing the door panel toward the lifting shell 4501, so that the outer end of the door panel contacts the roller 4502 that can be actively rotated by the feed / unload motor 4505, the pushing cylinder 402, the pushing piston 404, the connecting plate 403 and the pushing plate 405 are reset, and then the feed / unload motor 4505 operates, and the roller 4502 rotates, so that the door panel is separated from the hot pressing plate 3, and the lifting motor 4504 and the lifting screw 4503 cooperate to make the lifting shell 4501 descend, and the unloading is completed.

[0085] Embodiment 3:

[0086] like Figure 3 and Figure 6 As shown, in the present embodiment, in addition to the structural features of the aforementioned embodiments, the rolling device 7 also includes a pair of equipment cavities 703, which are respectively arranged inside the front and rear sides of the corresponding hot pressing plate 3 and are respectively connected to each slot 702; a pair of opening and closing drive units 10, which are used to drive the corresponding blocking cover 8 to disengage / block the corresponding slot 702; a pair of lifting drive units 11, which are used to drive the corresponding groups of rollers 701 to rise and fall; a pair of transmission frames 12, which are used to connect the opening and closing drive unit 10 with the lifting drive unit 11 and the transverse sliding frame 901.

[0088] Furthermore, the blocking cover 8 includes a cover body 801, which can be movably inserted in the groove 702; a baffle 802, which is arranged on the side wall of the cover body 801 facing the transmission frame 12; a plurality of guide blocks 803, which are fixedly installed on the side wall of the equipment cavity 703 away from the transmission frame 12; a plurality of baffles 804, which are fixedly installed at intervals on the side wall of the cover body 801 away from the transmission frame 12, and are staggered with each guide block 803, and the left and right side walls of the groove 702 and the cover body 801 are inclined, and the lower end is inclined toward the transmission frame 12, and the side wall of each guide block 803 is smoothly connected to the corresponding side wall of the groove 702.

[0089] Furthermore, the lifting drive unit 11 includes a pair of side panels 1101, which are fixedly installed in the equipment cavity 703; a lifting block 1102, which can be lifted and installed between the pair of side panels 1101 and is located below the slot 702; a through slot, which is arranged at the bottom of the side panel 1101 close to the transmission frame 12; a transverse slide 1103, which can be slidably installed in the through slot and driven to move horizontally by the transmission frame 12; a plurality of swing arms 1104, the upper ends of which are hinged to the bottom surface of the lifting block 1102 and the lower ends of which are hinged to the top surface of the transverse slide 1103, and each roller 701 can be rotatably installed on the top of the lifting block 1102.

[0090] Furthermore, the transmission frame 12 includes a transverse push plate 1201, which can be laterally slidably installed on the bottom inner wall of the equipment cavity 703; a transmission surface, which is arranged on the top of the transverse push plate 1201, including a descending surface 1202, a connecting surface 1203 and an ascending surface 1204; a plurality of transmission blocks 1205, the inner ends of which are fixedly installed on the transverse push plate 1201 and the outer ends extend out of the hot pressing plate 3; a plurality of guide slopes 1206, which are arranged on the side of the outer end of each transmission block 1205 facing the adjacent transverse sliding frame 901; the lower end of the lifting push rod 1011 is in transmission cooperation with the transmission surface.

[0091] In this embodiment of the present application, due to the adoption of the above-mentioned structure, when the hot pressing top plate 2 and the hot pressing plate 3 are separated, a pair of transverse sliding frames 901 move away from each other and move toward each transmission block 1205 of the corresponding transmission frame 12. As the hot pressing top plate 2 and the hot pressing plate 3 are gradually separated, a pair of transverse sliding frames 901 move further away from each other, and cooperate with the corresponding guide inclined surfaces 1206 on each transmission block 1205 to push the transverse push plate 1201 to move in the direction of the transverse slide plate 1103. In this process, the lifting push rod 1011 slides from the descending surface 1202 to the connecting surface 1203, and finally slides to the ascending surface 1204, during this process, the transmission piston 1005 rises in the transmission cylinder 1004, and the hydraulic oil in the inner cavity of the transmission cylinder 1004 is squeezed into the transverse cylinder 1001 through the connecting oil pipe 1006, so that the transverse piston 1002 and the transverse push rod 1003 move away from the slot 702. Correspondingly, the transverse slider 1008 slides in the transverse slide groove 1007 toward the transmission frame 12, and through the cooperation of the transmission column 1010 and the linkage groove 1009, the cover body 801 is dragged to move in the direction of the transmission frame 12. Due to the left and right sides of the cover body 801 of the slot 702 The walls are all inclined, and the cover body 801 gradually drops below the notch 702 during the movement of the transmission frame 12. As the transverse piston 1002 and the transverse push rod 1003 continue to move, the cover body 801 eventually completely leaves the notch 702, and then the inner end of the transverse push plate 1201 contacts the transverse slide plate 1103, pushing the transverse slide plate 1103 to move between the pair of side plates 1101. During this process, the lower end of the lifting push rod 1011 only slides on the rising surface 1204 and will no longer drop. The position of the cover body 801 is fixed, and the transverse slide plate 1103 continues to move toward the pair of side plates. 1101, so that each swing arm 1104 swings around the hinge points at both ends, and lifts up the lifting block 1102, so that the lifting block 1102 rises until the top of each roller 701 extends out of the slot 702. At this time, the hot pressing top plate 2 and the hot pressing plate 3 are separated to the maximum distance, and the outer wall of each transverse sliding frame 901 abuts against the outer end surface of the corresponding transmission block 1205. In this state, the lower surface of the door panel passing the top of the hot pressing plate 3 can only contact with each roller 701, and rolling friction occurs, which reduces the friction loss on the lower surface of the door panel when moving, and improves the aesthetics and quality of the finished product.

[0092] A spring 1 may be provided between the outer side plate 1101 and the transverse push plate 1201. When the transverse push plate 1201 approaches the side plate 1101, the spring 1 is compressed to store elastic potential energy.

[0093] A second spring is arranged between the top of the transmission piston 1005 and the top of the inner cavity of the transmission cylinder 1004. When the transmission piston 1005 rises, the second spring is compressed to store elastic potential energy.

[0094] When the hot pressing top plate 2 and the hot pressing plate 3 are closed, a pair of transverse sliding frames 901 approach each other and move in the direction away from the corresponding transmission block 1205 until each transverse sliding frame 901 is separated from the corresponding transmission block 1205. Spring 1 exerts elastic potential energy to push the transverse push plate 1201 in the direction away from the side plate 1101. Under the action of gravity, the lifting block 1102 descends, and each roller 701 retracts into the equipment cavity 703 through the slot 702. Each swing arm 1104 swings around the hinge points at both ends and pushes the transverse slide plate 1103 to the outside of a pair of side plates 1101. During this process, the lower end of the lifting push rod 1011 is still in contact with the rising surface 1204 until each roller 701 falls below the transverse sliding block 1008, and the transverse push plate 1201 continues to move. The lower end of the lifting push rod 1011 moves to the descending surface 1202 through the connecting surface 1203, and the spring 2 exerts elastic potential energy. The transmission piston 1005 is moved downward, and the hydraulic oil in the lateral cylinder 1001 is returned to the inner cavity of the transmission cylinder through the connecting oil pipe 1006. The lateral piston 1002 and the lateral push rod 1003 move toward the notch 702. During this process, the lateral slider 1008 moves toward the notch 702, and the cover 801 also moves toward the notch 702 under the cooperation of the linkage groove 1009 and the transmission column 1010. The left end of the cover 801 Restricted by the contact with each guide block 803, as the cover body 801 continues to move toward the slot 702, its left end side wall cooperates with each guide block 803, so that the cover body 801 rises into the slot 702 during the movement until the top surface of the cover body 801 is flush with the top surface of the hot pressing plate 3. At this time, the top surfaces of the stop bar 802 and each stop block 804 are in contact with the top surface of the equipment cavity 703. At this time, the hot pressing top plate 2 and each hot pressing plate 3 are closed, and the hot pressing operation on the door panel can be carried out.

[0095] When the roller 701 extends out of the slot 702 to lift the door panel, the swing arms 1104 and the transverse sliding plate 1103 are not perpendicular to each other, and the lower end of each swing arm 1104 is inclined toward the transverse sliding slider 1008, so that when the transverse sliding slider 1008 moves outward from the side panel 1101, the lifting block 1102 is reset under the action of gravity.
