[0014] The beneficial effects of the present invention are: 1. By installing a rotatable quadrangular prism, the four sides of which are all equipped with a first placement plate, the polystyrene EPS dyed plastic sheet can be placed on the first placement plate in the loading and unloading area, and then the composite sheet to be composited can be inserted into the installation opening of the second placement plate to complete the loading process, which is convenient for loading.

By installing the vacuum mechanism and starting the air pump, the air inside the pressing plate can be simultaneously extracted through the suction pipe, the hollow shaft, and the four branch pipes to generate negative pressure, so that the composite sheet can be adsorbed on the surface of the pressing plate. After the pressing is completed, the composite sheet can be rotated 90° to a vertical state with the pressing plate to facilitate the subsequent cooling and unloading process.

[0017] 4. By installing multiple air blowing pipes in the cooling zone, the air pump inhales air while exhausting it at the other end. The exhausted gas is blown toward the composite board through the air outlet holes on the multiple air blowing pipes, which can effectively cool down the board.

[0018] 5. By installing the opening and closing mechanism, when the laminated sheet returns to the loading and unloading area again, the magnetic block and the magnetic slider have the same poles that repel each other, which can push the baffle plate upward to close the branch pipe, interrupt the air extraction, and eliminate the negative pressure. The laminated sheet can automatically fall out of the installation port, completing the automatic unloading process. BRIEF DESCRIPTION OF THE DRAWINGS

A hollow shaft 5 is rotatably connected to the workbench 1, and a quadrangular prism 4 is fixed to the upper end of the hollow shaft 5. The four sides of the quadrangular prism 4 correspond to the loading and unloading area, the pressing area, the cooling area, and the heating area, respectively. The bottom of the four sides of the quadrangular prism 4 is fixed with a first placement plate 3 for placing the polystyrene EPS dyed plastic sheet. The four A second placement plate 7 that can rotate 90° is also installed on the side, which is used to place the plate material composited with the polystyrene EPS dyed plastic sheet. The second placement plate 7 is provided with an installation opening, and a pressing plate 8 that can move along its thickness direction is installed in the installation opening. The pressing plate 8 is hollow and has a plurality of negative pressure holes 24 evenly distributed on the surface. The hollow pressing plate 8 is connected to the hollow shaft 5 through a branch pipe 6. An exhaust mechanism that can extract the air in the pressing plate 8 is installed at the bottom of the workbench 1, and a heating plate 2 located above the first placement plate 3 is installed in the heating zone.

[0024] Furthermore, a motor 18 is installed at the bottom of the workbench 1, and the lower end of the hollow shaft 5 extends from the bottom of the workbench 1. The extended end of the hollow shaft 5 is connected to the output end of the motor 18 through a pair of first gears 19. When the motor 18 is started, the hollow shaft 5 is driven to rotate through the pair of first gears 19, and then the quadrangular prism 4 is driven to rotate, passing through the loading and unloading area, heating area, pressing area and cooling area in sequence.

[0025] Furthermore, two fixed blocks are fixed on the four sides of the quadrangular prism 4, and the second placement plate 7 is rotatably connected between the two fixed blocks through a rotating rod. The second gear 13 is fixed on both ends of the rotating rod. Two sliding grooves 29 are provided on the four sides of the quadrangular prism 4.

The conductive block 12 is externally connected to a power supply, and the first spring 14 is energized and contracts, pulling the gear plate 15 upward, and driving the second placement plate 7 to rotate 90° through the second gear 13 and the rotating rod. The plate is adsorbed during the rotation process, so that the plate is bonded to the melted surface of the polystyrene EPS dyed plastic sheet.

[0027] Furthermore, mounting grooves 23 are provided at the four corners of the mounting opening, and a connecting plate is elastically installed in the mounting groove 23 through the second spring 22. The connecting plate is fixedly connected to the pressure plate 8, and a trigger switch 16 cooperating with the tooth plate 15 is installed on the inner wall of the slide groove 29. The trigger switch 16 is electrically connected to the first spring 14 and the second spring 22. While fitting, the tooth plate 15 moves up to the extreme position and contacts the trigger switch 16, thereby turning on the circuit of the second spring 22. The second spring 22 is energized and contracts, and the pressure plate 8 is pulled to move through the connecting plate, so that the plate material and the polystyrene EPS dyed plastic sheet can be pressed.

[0028] Specifically, the vacuum mechanism includes an air pump 21 installed at the bottom of the workbench 1. The suction end of the air pump 21 is connected to the suction pipe 20. The end of the suction pipe 20 is connected to the lower end of the hollow shaft 5 through a rotating joint. The hollow shaft 5 does not affect the vacuum process during rotation.

[0029] Furthermore, the air outlet end of the air pump 21 is connected to an air outlet pipe 9, which extends to the cooling zone. The air outlet pipe 9 is connected to a plurality of vertically arranged air blowing pipes 10, and a plurality of air outlet holes are arranged on the side wall of the air blowing pipe 10.

[0030] Furthermore, four grooves 27 corresponding to the four branch pipes 6 are provided at the bottom of the quadrangular prism 4 , and opening and closing mechanisms are installed in the four grooves 27 for controlling the opening and closing of the branch pipes 6 .

[0031] Specifically, the opening and closing mechanism includes a magnetic slider 28 arranged in the groove 27, a baffle 25 is fixed on the upper end of the magnetic slider 28, a channel for the baffle 25 to pass through is provided between the branch pipe 6 and the groove 27, the magnetic slider 28 is elastically connected to the bottom of the groove 27 by a third spring 26, the workbench 1 is located in the loading and unloading area and is installed with a magnetic block 11 that cooperates with the magnetic slider 28, and the plate after cooling returns to the loading and unloading area, at this time the magnetic slider 28 rotates to the position corresponding to the magnetic block 11, because the opposite surfaces of the magnetic slider 28 and the magnetic block 11 repel each other with the same poles, and the repulsive force is greater than the elastic force of the third spring 26, and the baffle 25 can be pushed up into the branch pipe 6, closing the branch pipe 6, interrupting the air extraction, and the negative pressure disappearing, and the pressed plate can automatically fall out of the installation port, completing the automatic unloading process.

[0032] First, place the polystyrene EPS dyed plastic sheet on the first placement plate 3, then insert the plate to be composited into the installation port on the second placement plate 7, start the air pump 21, and extract the air inside the pressure plate 8 through the suction pipe 20, the hollow shaft 5 and the branch pipe 6. After the extraction, negative pressure is formed, and the plate to be composited is adsorbed through the uniformly distributed negative pressure holes 24. Start the motor 18, and drive the hollow shaft 5 to rotate through a pair of first gears 19, and then drive the quadrangular prism 4 to rotate, so that the first placement plate 3 loaded with the polystyrene EPS dyed plastic sheet rotates to the heating zone, and start the heating plate 2. The heat generated by the heating plate 2 is radiated to the surface of the polystyrene EPS dyed plastic sheet, so that the surface is melted, and then the heat is radiated to the surface of the polystyrene EPS dyed plastic sheet with the quadrangular prism 4. Rotate to the pressing area, at this time, the conductive head 17 on the corresponding side of the bottom of the quadrangular prism 4 contacts the conductive block 12, the circuit is turned on, and the external power supply energizes the two first springs 14 at the same time. The first spring 14 is energized and contracts, pulling the tooth plate 15 to move up, and the second placement plate 7 is driven to rotate 90° through the second gear 13 and the rotating rod. The plate is adsorbed during the rotation process, so that the plate and the melted surface of the polystyrene EPS dyed plastic sheet are bonded. At the same time, the tooth plate 15 moves up to the extreme position and contacts the trigger switch 16, turning on the circuit of the second spring 22. The second spring 22 is energized and contracts, and the pressing plate 8 is pulled to move through the connecting plate, so that the plate and the polystyrene EPS dyed plastic sheet can be pressed.

[0033] After pressing, the quadrangular prism 4 continues to rotate. At this time, the conductive head 17 leaves the conductive block 12, the circuit is disconnected, the first spring 14 and the second spring 22 are reset, and then the tooth plate 15 moves down, so that the second placement plate 7 rotates to a vertical state. Since the adsorption state is maintained, the pressed sheet will rotate to a vertical state with the pressing plate 8. After the whole rotates to the cooling zone, the air pump 21 discharges the sucked gas into the multiple blowing pipes 10 through the outlet pipe 9, and finally blows it to the pressed sheet from the multiple outlet holes to cool it down.

[0034] After cooling, the sheet returns to the loading and unloading area. At this time, the magnetic slider 28 rotates to the position corresponding to the magnetic block 11. Since the opposite surfaces of the magnetic slider 28 and the magnetic block 11 repel each other with the same poles, and the repulsive force is greater than the elastic force of the third spring 26, the baffle 25 can be pushed upward to enter the branch pipe 6, closing the branch pipe 6, interrupting the air extraction, and eliminating the negative pressure. The pressed sheet can automatically fall out of the installation port, completing the automatic unloading process.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
