[0035] The preheating assembly comprises first bellows 302, first gas conveying pipes 303, second gas conveying pipes 304, second bellows 306, third bellows 307 and a gas storage tank 308; the upper die plate 4 and the lower die plate 5 are hollow; the upper support 7 and the lower support 8 on the same connecting cylinder 6 are fixedly connected with an expansion plate 11; the first bellows 302 is communicated with the right connecting cylinder 6; the gas storage tank 308 is fixedly connected to the right upper side of the workbench 1; an electric valve is arranged in the gas storage tank 308; a pump is arranged in the gas storage tank 308; the first bellows 302 is communicated with the gas storage tank 308; the gas storage tank 308 is communicated with a plurality of first gas conveying pipes 303; the other ends of the first gas conveying pipes 303 are communicated with the upper die plate 4; the gas storage tank 308 is communicated with a plurality of second gas conveying pipes 304; the other ends of the second gas conveying pipes 304 are communicated with the lower die plate 5; the second bellows 306 is communicated with the left side of the lower die plate 5; the other end of the second bellows 306 is communicated with the outside of the protective cover 2; the third bellows 307 is communicated with the left side of the upper die plate 4; and the other end of the third bellows 307 is communicated with the outside of the protective cover 2.

[0036] The third driving member 9 is further arranged; one third driving member 9 for adjusting the distance between the lower support 8 and the upper support 7 is fixedly connected to each of the two connecting cylinders 6, and the third driving member 9 is an electric push rod; and the connecting cylinder 6 is fixedly connected with the upper support 7 through the output end of the third driving member 9.

[0037] Before the polycarbonate plate 3 is hot-pressed and bent, first, the first drive 305 on the right side wall of the protective cover 2 drives the corresponding limiting plate 301 to move to the right, compresses the corresponding first bellows 302, and drives the corresponding connecting cylinder 6, upper support 7, lower support 8, third drive 9, connecting pipe 10 and telescopic plate 11 to move to the right, so as to increase the distance between the upper support plate 7001 and the lower support plate 8001 on the left and right sides of the first drive 305. Then, the staff inserts the embedded cavity 3001 on the polycarbonate plate 3 into the upper support plate 7001 and the lower support plate 8001 on the left side, and then controls the first drive 305 to drive the upper support plate 7001 and the lower support plate 8001 on the right side to move left to reset, so as to clamp and fix the polycarbonate plate 3. Then, control the electric sliding block 202 to slide forward along the sliding rail 201 until the connecting plate 203 and the heating wire 204 move directly above the polycarbonate plate 3, and then control the heating wire 204 to work, so that the heat generated by the working heating wire 204 is radiated to the polycarbonate plate 3, so that the polycarbonate plate 3 is softened. It should be noted that the temperature radiated to the polycarbonate plate 3 needs to be controlled between eighty degrees and one hundred and twenty degrees. Specifically, a temperature sensor can be added in the connecting plate 203 and the protective cover 2 to monitor the working heating wire 204, and the time for the heat generated by the working heating wire 204 to be radiated to the polycarbonate plate 3 is set by the staff in advance according to the thickness of the polycarbonate plate 3. After the specified time for the heat generated by the working heating wire 204 to be radiated to the polycarbonate plate 3, control the electric sliding block 202 to reset the connecting plate 203 and the heating wire 204, and then control the second drive 101 to drive the fixed plate 102 and the upper mold plate 4 to move downward, so that the softened polycarbonate plate 3 is pressed on the lower mold plate 5 by the upper mold plate 4, and the polycarbonate plate 3 is adaptively bent to complete the hot-pressing and bending of the polycarbonate plate 3. It should be noted that during the process of the softened polycarbonate plate 3 being pressed on the lower mold plate 5 by the upper mold plate 4, the polycarbonate plate 3 will force the connecting cylinder 6 to follow the polycarbonate plate 3 to bend and adaptively rotate, and the torsional spring at the connecting position of the connecting cylinder 6 and the limiting plate 301 is compressed. Thus, during the hot-pressing process of the polycarbonate plate 3, the edges and corners of the polycarbonate plate 3 are supported by the upper support plate 7001 and the lower support plate 8001, so as to reduce the deformation or damage of the edges and corners of the polycarbonate plate 3.

[0038] After the hot-press bending work of the polycarbonate plate 3 is completed, the second driving member 101 is controlled to reset the fixed plate 102 and the upper mold plate 4, and at the same time, the air blower outside the protective cover 2 is controlled to blow air, so that the external air is blown from left to right into the embedded cavity 3001 of the polycarbonate plate 3 through the connecting pipe 10, the connecting cylinder 6 and the lower support plate 8001, so that the polycarbonate plate 3 is cooled and cooled under the blowing of the airflow, and the airflow circulating in the embedded cavity 3001 is discharged to the outside through the right lower support plate 8001 and the right connecting cylinder 6. It should be noted that the airflow blown from left to right into the polycarbonate plate 3 will be blocked by the right telescopic plate 11, so that the airflow gradually enters the lower support plate 8001 of the right lower support 8, and then enters the first bellows 302 along the right lower support plate 8001 and the right connecting cylinder 6. Then the airflow enters the gas storage tank 308 along the first bellows 302 and is stored, at this time, the airflow stored in the gas storage tank 308 has a certain heat, when the worker takes the hot-pressed polycarbonate plate 3 from the equipment and places the polycarbonate plate 3 again during the interval of the hot-pressing, the electric valve in the gas storage tank 308 is controlled to open, and then the pump on the gas storage tank 308 is controlled to transmit the hot air in the gas storage tank 308 to the first gas conveying pipe 303 and the second gas conveying pipe 304 respectively, so that the hot air along the first gas conveying pipe 303 enters the upper mold plate 4 and is blown out to the outside of the protective cover 2 along the upper mold plate 4 from the third bellows 307, so that the hot air flowing along the upper mold plate 4 exchanges heat with the upper mold plate 4, so that the temperature of the upper mold plate 4 rises, realizing the preheating of the upper mold plate 4. Similarly, the hot air along the second gas conveying pipe 304 will enter the lower mold plate 5 and be blown out to the outside of the protective cover 2 along the lower mold plate 5 from the second bellows 306, so that the hot air flowing along the lower mold plate 5 exchanges heat with the lower mold plate 5, so that the temperature of the lower mold plate 5 rises, realizing the preheating of the lower mold plate 5, and ensuring that the surface temperatures of the upper mold plate 4 and the lower mold plate 5 are uniform, avoiding that the temperature difference between the upper mold plate 4 and the lower mold plate 5 and the softened polycarbonate plate 3 is too large, and the surface temperature of the upper mold plate 4 and the lower mold plate 5 is not uniform, which causes the polycarbonate plate 3 to deform or crack during the hot-pressing process, affecting the quality of the polycarbonate plate 3. After the heating work of the electric heating wire 204 on the polycarbonate plate 3 is completed, the gas storage tank 308 stops conveying hot air to the first gas conveying pipe 303 and the second gas conveying pipe 304. Compared with the existing method of directly heating the upper mold plate 4 and the lower mold plate 5 by electric heating to realize the preheating of the upper mold plate 4 and the lower mold plate 5, the present application reuses the airflow for cooling the polycarbonate plate 3, so that the airflow for cooling the polycarbonate plate 3 becomes hot air, and the hot air is used to preheat the upper mold plate 4 and the lower mold plate 5, which is conducive to energy saving.

[0039] It should be noted that before placing the polycarbonate plate 3 on the upper support plate 7001 and the lower support plate 8001, the worker can control the third driving member 9 to drive the upper support 7 and the upper support plate 7001 to move upwards, so that the telescopic plate 11 is stretched, so that the distance between the adjacent upper support 7 and the lower support 8 is increased, so as to adapt to polycarbonate plates 3 of different thicknesses.

[0040] The airflow flow channel in the left lower support plate 8001 is arranged in a rightwardly tapered manner; for improving the flow speed of the airflow, and improving the cooling effect of the airflow on the polycarbonate plate 3.

[0041] Embodiment 2

[0042] On the basis of embodiment 1, as shown in Figure 2 、 Figure 3 、 Figure 9 and Figure 10 , it further comprises a cleaning assembly, the cleaning assembly comprising a fourth driving member 401, a blowing pipe 402, a blowing pipe 403 and a fourth bellow 404; two left and right symmetrical fourth driving members 401 are fixedly connected in the protective cover 2, and the fourth driving member 401 is an electric push rod; the telescopic ends of the two fourth driving members 401 are commonly fixedly connected with the blowing pipe 402; a plurality of blowing pipes 403 are communicated at the rear side of the blowing pipe 402; the blowing pipe 402 is communicated with the fourth bellow 404; the fourth bellow 404 is communicated with the gas storage tank 308.

[0043] The rear side of the protective cover 2 is provided with a sliding door 2001, which is convenient for the worker to clean the dust falling on the workbench 1.

[0044] Before the staff places another polycarbonate plate 3 to be hot-pressed on the upper support plate 7001 and the lower support plate 8001, the fourth drive member 401 is controlled to drive the air blowing pipe 402 and the air blowing pipe 403 to move downward, and the fourth bellows 404 is adaptively moved to avoid the staff placing the polycarbonate plate 3. After the staff places another polycarbonate plate 3 to be hot-pressed on the upper support plate 7001 and the lower support plate 8001, the pump in the gas storage tank 308 is controlled to blow the hot air out of the fourth bellows 404, the air blowing pipe 402 and the air blowing pipe 403, and at the same time, the fourth drive member 401 is controlled to drive the air blowing pipe 402 and the air blowing pipe 403 to move upward first to reset, and then to move up and down reciprocatingly, so that the hot air is blown to the upper surface and the lower surface of the polycarbonate plate 3, and the dust on the surface of the polycarbonate plate 3 is moved backward under the action of the airflow and then falls onto the workbench 1, thereby realizing the cleaning of the dust on the surface of the polycarbonate plate 3, avoiding the adhesion of dust on the surface of the polycarbonate plate 3, causing the appearance of dust spots on the surface of the polycarbonate plate 3 after the subsequent hot pressing, and affecting the quality of the polycarbonate plate 3. In addition, since the airflow used for cleaning is hot air, the polycarbonate plate 3 can be preheated while being cleaned, which is beneficial to the uniform softening of the polycarbonate plate 3 in the subsequent heating process. It should be noted that when the polycarbonate plate 3 is heated and softened by the electric heating wire 204, the pump in the gas storage tank 308 stops discharging hot air into the fourth bellows 404, and after the hot pressing of the polycarbonate plate 3 required for production is completed, the staff can open the sliding door 2001 at the rear side of the protective cover 2 to clean the dust falling on the workbench 1.

[0045] Except for the air blowing pipe 403 opposite to the center of the polycarbonate plate 3, the rest of the air blowing pipes 403 are inclined towards the center of the polycarbonate plate 3. When the hot air is blown to the polycarbonate plate 3 along the air blowing pipe 403, the hot air blown by the left and right air blowing pipes 403 is gathered towards the center on the polycarbonate plate 3, and then is blown backward by the air blowing pipe 403 opposite to the center of the polycarbonate plate 3, so that the hot air carries the dust away from the connecting cylinder 6 and other parts, preventing a large amount of dust from adhering to the connecting cylinder 6 and other parts, and reducing the cleaning period of the connecting cylinder 6 and other parts.

[0046] Each air blowing pipe 403 is open on the side close to the polycarbonate plate 3; the coverage area of the airflow blown out of the air blowing pipe 403 on the surface of the polycarbonate plate 3 is increased, and the cleaning effect of the airflow on the dust on the surface of the polycarbonate plate 3 is improved.

[0047] The application is described in detail above, and the principles and implementation modes of the application are described by applying specific examples. The above description of the examples is only used to help understand the method of the application and its core idea; meanwhile, for those skilled in the art, according to the idea of the application, the specific implementation modes and application ranges will have changes, and the above description should not be understood as a limitation on the application.
