[0064] A connecting seat 816 is fixedly installed on the transmission chain 815, and the other end of the connecting seat 816 is fixedly connected to the side of the base plate 3; the rotating shaft 82 is fixedly installed on both ends of the bottom surface of the base plate 3 through brackets, and the two ends of the rotating shaft 82 are rotatably installed with gears 83 through bearings; a number of spur plates 84 are fixedly installed on the inner wall of the frame 2, and the gear 83 is meshed and connected with the spur plates 84 in opposite positions; the rotation of the transmission chain 815 drives the connecting seat 816 to move up and down, and then drives the base plate 3, the hot pressing plate 4 and the load-bearing part 5 to move up and down; the up and down movement of the base plate 3 drives the rotating shaft 82 to move, and then the gear 83 rotates on the spur plates 84, assisting the movement of the base plate 3 while limiting the moving direction of the base plate 3.

[0065] There are several mounting frames 91, which are located on both sides of the hot pressing plate 4, and the bottom end of the mounting frame 91 is fixedly connected to the frame 2; there are several cylinders 92, which are respectively fixedly installed on the top of the mounting frame 91, and the output end of the cylinder 92 faces the hot pressing plate 4; the limit block 93 is fixedly connected to the output end of the cylinder 92; there are several limit grooves 94 on both sides of the hot pressing plate 4, and the position of the limit groove 94 is opposite to the limit block 93; the limit block 93 is driven to move by the output end of the cylinder 92, and the limit block 93 is installed in the limit groove 94 corresponding to the hot pressing plate 4, thereby providing limit support for the hot pressing plate 4 and the load-bearing part 5.

[0066] Rotating shafts are fixedly installed on both sides of the load-bearing member 5, and transmission wheels are rotatably installed on both ends of the rotating shafts through bearings. The transmission wheels are meshed and connected with the spur plates 84 in the frame 2, so that the load-bearing member 5 is supported while also limiting its moving direction.

[0067] When the door panel is hot-pressed, the limit block 93 on the cylinder 92 is movably installed in the limit groove 94 of the bottom hot pressing plate 4. The cylinder 92 is started, and the output end of the cylinder 92 is extended back, and drives the limit block 93 to disengage from the limit groove 94. At this time, the hot pressing plate 4 is released from the locked state; then the motor 811 is started, and the motor 811 drives the driving wheel 812 to rotate clockwise, and the driving wheel 812 drives the driven wheel 814 and the transmission chain 815 to rotate clockwise. During the clockwise rotation of the transmission chain 815, the transmission chain 815 drives the bottom plate 3 to move downward, and the hot pressing plate 4 and the load-bearing part 5 move downward synchronously. At the same time, the gear 83 and the transmission wheel rotate on the spur plate 84.

[0068] The transmission chain 815 drives the hot pressing plate 4 above the bottom layer to move to the side of the limit block 93, that is, the second-to-last hot pressing plate 4 moves to the side of the limit block 93, the transmission chain 815 stops moving, and the cylinder 92 is started. The output end of the cylinder 92 moves the limit block 93 to the limit groove 94 again, and limits and fixes part of the hot pressing plate 4 and the load-bearing part 5; then the motor 811 is started again, and the transmission chain 815 drives the bottom plate 3 and the bottom hot pressing plate 4 to move downward. At this time, a gap is generated between the bottom hot pressing plate 4 and the hot pressing plate 4 above it. At this time, the loading mechanism 1 can transfer the door panel to the bottom hot pressing plate 4.

[0069] Then the motor 811 drives the transmission chain 815 to rotate counterclockwise, and at this time the transmission chain 815 drives the bottom plate 3, the bottom hot pressing plate 4 and the door panel to move upward, until the door panel abuts the second-to-last hot pressing plate 4 and the motor 811 stops working; at this time, the cylinder 92 is started, and the cylinder 92 drives the limit block 93 to disengage from the limit groove 94, and at the same time, the motor 811 drives the bottom plate 3, the hot pressing plate 4, the door panel and the load-bearing piece 5 to move downward again, until the third-to-last hot pressing plate 4 moves to the side of the limit block 93 and stops working, and so on, until a door panel is placed between adjacent hot pressing plates 4, and finally the door panel is hot-pressed and glued together through the load-bearing piece 5 and the hot pressing plate 4.

[0076] In this embodiment of the present application, due to the adoption of the above-mentioned structure, the fixed plate 102 is fixedly installed on the frame 2 and is located on the opposite side of the input end of the frame 2; the fixed plate 102 is laterally fixedly installed with a slide rail 101 on the side facing the frame 2, and the opening of the slide rail 101 faces the hot pressing plate 4; the opposite surface of the slide rail 101 is movably provided with a slide rail 2 103, and the openings of the slide rail 101 and the slide rail 2 103 are opposite to each other and perpendicular to each other, that is, the slide rail 2 103 is relatively perpendicular to the hot pressing plate 4; at the same time, the slide rail 101 and the slide rail 2 103 are rotatably connected, and the two ends of the slide rail 101 are open, while the two ends of the slide rail 2 103 are closed, which is used to prevent the limit member 104 in the slide rail 2 103 from sliding out of the slide rail 2 103.

[0077] The limiting member 104 includes a slider, a fixing rod and a connecting plate. The two pairs of sliders are slidably arranged in the slide rail 101 and the slide rail 2 103 respectively, and the slide rail 101 and the slide rail 2 103 are provided with a return spring 106. The sliders are located at both ends of the return spring 106 and are fixedly connected to the return spring 106. At the same time, the outer side of each slider is fixedly connected with a connecting plate through a fixing rod, and the connecting plate is slidably installed in the slide rail 101 and the slide rail 2 103.

[0078] The top of the slider and the outer sides of the slide rail 101 and the slide rail 2 103 are all provided with rotating seats, and two pairs of hinged rods 107 are provided, and the two pairs of hinged rods 107 are respectively rotatably connected to the outer side of the slide rail 101 and the rotating seat on the slider inside the slide rail 2 103, and the slider inside the slide rail 101 and the rotating seat on the outer side of the slide rail 2 103, so that the slide rail 101 and the slide rail 2 103 are rotatably connected, and by pushing the slide rail 2 103 to move toward the direction of the slide rail 101, the slider and the connecting plate are driven to slide in the slide rails 101 and the slide rail 2 103, and the reset spring 106 is deformed at the same time.

[0079] The fixed plate 102 is fixedly provided with a plurality of limit seats 111, and the limit seats 111 are located on the side of the slide rail 101; a small hole is provided at the bottom of the slide rail 101, and a pair of limit rods 112 are movably provided on both sides of the slide rail 101, and the top ends are movably installed in the small holes. At the same time, connecting rods 113 are movably provided on both sides of the slide rail 101, and the bottom ends of the connecting rods 113 are rotatably connected to the connecting rods 113, and the top ends are rotatably installed on the sides of the sliders in the slide rails 103, so that the movement of the slider can drive the connecting rods 113 to rotate, and then the rotation of the connecting rods 113 drives the movement of the limit rods 112; at the same time, the limit seats 111 are opposite to the connecting plate and the limit plates, and can limit the moving distances of the connecting plate and the limit rods 112.

[0080] The mounting plate 121 is movably arranged below the hot pressing plate 4, and a number of elastic members 122 are arranged between the hot pressing plate 4 and the mounting plate 121, and the two ends of the elastic member 122 are fixedly connected to the bottom plate 3 of the hot pressing plate 4 and the top surface of the mounting plate 121; the elastic member 122 includes a fixed sleeve, a movable rod, a limiting plate and an elastic spring; the top end of the fixed sleeve is fixedly connected to the hot pressing plate 4, the limiting plate is movably arranged in the fixed sleeve, and the diameter of the mounting hole at the bottom of the fixed sleeve is smaller than the diameter of the limiting plate, which is used to limit the position of the limiting plate; the top end of the movable rod is fixedly connected to the limiting plate, and the bottom end of the movable rod extends to the outside of the fixed sleeve and is fixedly connected to the mounting plate 121; the elastic spring is sleeved outside the fixed sleeve and the movable rod, and the two ends are fixedly connected to the hot pressing plate 4 and the mounting plate 121.

[0081] An arc-shaped flexible metal pressing sheet 123 is arranged below the mounting plate 121. The material of the flexible metal pressing sheet 123 is flexible metal to prevent the flexible metal pressing sheet 123 from being damaged when the hot pressing plates 4 on both sides are pressed together; the two ends of the flexible metal pressing sheet 123 are detachably mounted on the two ends of the hot pressing plate 4 by fixing parts (such as screws and bolts); a plurality of telescopic rods 124 are fixedly arranged between the mounting plate 121 and the flexible metal pressing sheet 123, and the telescopic rods 124 can be telescoped and extended to support the flexible metal pressing sheet 123; a buffer spring 125 is sleeved on the outside of the telescopic rod 124, and the two ends of the buffer spring 125 are fixedly connected to the hot pressing plate 4 and the flexible metal pressing sheet 123, and the buffer spring 125 is sleeved with a spring soft cover 126, and the two ends of the spring soft cover 126 are fixedly connected to the hot pressing plate 4 and the flexible metal pressing sheet 123, and the telescopic rod 124 and the buffer spring 125 are protected by the spring soft cover 126.

[0082] The door panel is conveyed to the hot pressing plate 4 by the feeding mechanism 1. If the position of the door panel moves out of the working range of the hot pressing plate 4, the side of the door panel abuts against the second slide rail 103 and pushes the second slide rail 103 close to the first slide rail 101. At the same time, the distance between the first slide rail 101 and the second slide rail 103 is shortened by the movement of the second slide rail 103. The hinged rods 107 on both sides rotate synchronously and push the sliders in the first slide rail 101 and the second slide rail 103 to move away from each other. The movement of the slider drives the connecting plate to slide in the first slide rail 101 and the second slide rail 103, and at the same time, the reset spring 106 is pulled and deformed.

[0083] By sliding the slider in the slide rail 101, the connecting plates on both sides can be pushed into the corresponding limit seats 111. By sliding the slider in the slide rail 2 103, the connecting rods 113 on both sides are driven to rotate. The rotation of the connecting rods 113 drives the limit rods 112 to slide in the small holes. At the same time, the limit rods 112 can be moved to the corresponding limit seats 111, thereby limiting the moving distance of the slide rail 2 103. If the force on the slide rail 2 103 is unbalanced, that is, one side of the slide rail 2 103 is pushed by the door panel, the slide rail 2 103 approaches the slide rail 101, and the slides in the slide rail 101 and the slide rail 2 103 also slide. At the same time, the connecting block or the limit rod 112 on the corresponding side is installed in the limit seat 111 to limit the deviation of the slide rail 2 103, and the limit part 10 is protected.

[0084] After the door panel loses the thrust, the return spring 106 restores its deformation, driving the sliders in the slide rail 101 and the slide rail 2 103 to move closer to each other, and driving the hinged rods 107 on both sides to rotate, while pushing the slide rail 2 103 to move away from the slide rail 1 101. The movement of the slide rail 2 103 drives the door panel to move into the working range of the hot pressing plate 4. At this time, the connecting plate and the limit rod 112 also synchronously disengage from the limit seat 111.

[0085] When the hot pressing plate 4 performs hot pressing on the door panel, the hot pressing plate 4 is powered on for heating, and at the same time, the hot pressing plate 4 heats the flexible metal pressing sheet 123; when the hot pressing plate 4 is working, the bottom of the flexible metal pressing sheet 123 first contacts the door panel, and as the flexible metal pressing sheet 123 gradually approaches the door panel, the flexible metal pressing sheet 123 gradually deforms, and at the same time, pressure is exerted on the internal telescopic rod 124 and the buffer spring 125, and the telescopic rod 124 and the buffer spring 125 are extended and retracted, so as to buffer the pressure exerted on the door panel to a certain extent; as the flexible metal pressing sheet 123 gradually fits the door panel completely, The telescopic rod 124 inside the door panel reaches the deformation limit, and at the same time, the flexible metal pressing plate 123 is supported by the telescopic rod 124, and the buffer spring 125 is also supported to prevent the buffer spring 125 from plastic deformation; the hot pressing plate 4 continues to move toward the door panel, and pushes the movable rod and the fixed sleeve to slide relative to each other, and at the same time, pressure is generated on the elastic spring, which is deformed. Through the deformation of the buffer spring 125 and the elastic spring, the pressure on the door panel is buffered in layers to prevent the door panel from being subjected to excessive pressure and causing damage to the door panel.
