[0025] It also includes a third driving member 9; each of the two connecting cylinders 6 is fixedly connected with a third driving member 9 for adjusting the space between the lower support 8 and the upper support 7, and the third driving member 9 is an electric push rod; the connecting cylinder 6 is fixedly connected to the upper support 7 through the output end of the third driving member 9.

[0026] Before the polycarbonate sheet 3 is subjected to hot pressing and bending, first, the first driving member 305 located on the right side wall of the protective cover 2 is controlled to drive the corresponding limiting plate 301 to move to the right, and compress the corresponding first corrugated tube 302, and drive the corresponding connecting tube 6, the upper support 7, the lower support 8, the third driving member 9, the connecting tube 10 and the telescopic plate 11 to move to the right, so as to increase the distance between the upper supporting plate 7001 and the lower supporting plate 8001 on the left and right sides of the first driving member 305. Then, the staff inserts the embedding cavity 3001 on the polycarbonate sheet 3 into the upper supporting plate 7001 and the lower supporting plate 8001 on the left side. 01, and then control the first driving member 305 to drive the upper support plate 7001 and the lower support plate 8001 on the right side to move to the left and reset, so as to clamp and fix the polycarbonate plate 3, and then control the electric slider 202 to slide forward along the slide rail 201 until the connecting plate 203 and the electric heating wire 204 move to the top of the polycarbonate plate 3, and then control the electric heating wire 204 to perform heating work, so that the heat generated by the electric 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 80 degrees and 120 degrees, specifically Temperature sensors can be added to the connecting plate 203 and the protective cover 2 to monitor and control the operation of the heating wire 204. The time for the heat generated by the heating wire 204 to radiate to the polycarbonate plate 3 can be set by the staff in advance according to the thickness of the polycarbonate plate 3. After the heat generated by the heating wire 204 radiates to the polycarbonate plate 3 for a specified time, the electric slider 202 is controlled to drive the connecting plate 203 and the heating wire 204 to reset, and then the second driving member 101 is controlled to drive the fixing plate 102 and the upper template 4 to move downward, so that the softened polycarbonate plate 3 is squeezed onto the lower template 5 through the upper template 4, and the polycarbonate plate 3 is softened. The ester plate 3 is adaptively bent to complete the hot pressing bending of the polycarbonate plate 3. It should be noted that in the process of the upper template 4 squeezing the softened polycarbonate plate 3 onto the lower template 5, the polycarbonate plate 3 will force the connecting tube 6 to adaptively rotate following the bending of the polycarbonate plate 3 through the upper support plate 7001 and the lower support plate 8001, and the torsion spring at the connection between the connecting tube 6 and the limit plate 301 is compressed. Therefore, in the hot pressing process of the polycarbonate plate 3, the upper support plate 7001 and the lower support plate 8001 are used to provide support for the corners of the polycarbonate plate 3, thereby reducing the deformation or damage of the corners of the polycarbonate plate 3.

[0027] After the hot pressing and bending of the polycarbonate plate 3 is completed, the second driving member 101 is controlled to drive the fixing plate 102 and the upper template 4 to reset. At the same time, the second driving member 101 controls the blower located outside the protective cover 2 to blow air, so that the outside air is blown from left to right into the embedding cavity 3001 of the polycarbonate plate 3 through the connecting pipe 10, the connecting cylinder 6 and the lower supporting plate 8001, so that the polycarbonate plate 3 is cooled down under the blowing of the airflow, and the airflow circulating in the embedding cavity 3001 is discharged to the outside through the lower supporting plate 8001 on the right side and the connecting cylinder 6 on the right side. It should be noted that the airflow blowing from left to right into the polycarbonate plate 3 will be blocked by the telescopic plate 11 on the right side. , so that the airflow gradually enters the lower support plate 8001 of the right lower support device 8, and then enters the first corrugated pipe 302 along the right lower support plate 8001 and the right connecting tube 6, and then the airflow enters the air storage box 308 along the first corrugated pipe 302 for storage. At this time, the airflow stored in the air storage box 308 carries a certain amount of heat. When the staff removes the hot-pressed polycarbonate sheet 3 from the equipment and re-places the polycarbonate sheet 3 in the interval for hot pressing, the electric valve in the air storage box 308 is controlled to open, and then the pump on the air storage box 308 is controlled to transmit the hot air in the air storage box 308 to the first gas delivery pipe 303 and the second gas delivery pipe 304 respectively, so that the hot air flows along the first gas delivery pipe 303 and the second gas delivery pipe 304. The hot air from the air pipe 303 enters the upper template 4, and is blown out from the third corrugated pipe 307 along the upper template 4 to the outside of the protective cover 2, so that the hot air exchanges heat with the upper template 4 during the flow along the upper template 4, so that the temperature of the upper template 4 is increased, and the upper template 4 is preheated. Similarly, the hot air along the second air pipe 304 will enter the lower template 5, and is blown out from the second corrugated pipe 306 along the lower template 5 to the outside of the protective cover 2, so that the hot air exchanges heat with the lower template 5 during the flow along the lower template 5, so that the temperature of the lower template 5 is increased, and the preheating of the lower template 5 is achieved, and the surface temperature of the upper template 4 and the lower template 5 is uniform, so as to avoid the upper template 4 and the lower template 5 from being heated by the softened polycarbonate. The temperature difference between the plates 3 is too large, and the surface temperatures of the upper template 4 and the lower template 5 are uneven, 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 electric heating wire 204 finishes heating the polycarbonate plate 3, the air storage box 308 is controlled to stop supplying hot air to the first air pipe 303 and the second air pipe 304. Compared with the existing method of directly heating the upper template 4 and the lower template 5 by electric heating to preheat the upper template 4 and the lower template 5, the present invention reuses the airflow that cools the polycarbonate plate 3, so that after the airflow cools the polycarbonate plate 3 and turns it into hot air, the upper template 4 and the lower template 5 are preheated by the hot air, which is beneficial to energy saving.

[0028] It should be noted that before placing the polycarbonate plate 3 on the upper support plate 7001 and the lower support plate 8001, the staff can control the third driving member 9 to drive the upper support 7 and the upper support plate 7001 to move upward, so that the telescopic plate 11 is stretched, and the distance between adjacent upper supports 7 and lower supports 8 is increased to adapt to polycarbonate plates 3 of different thicknesses.

[0029] The air flow channel in the left lower support plate 8001 is configured to be tapered to the right, so as to increase the flow velocity of the air flow and improve the cooling effect of the air flow on the polycarbonate plate 3 .

[0030] Example 2 On the basis of Example 1, Figure 2 , Figure 3 , Fig. 9 and Fig.10 As shown, a cleaning component is also included, which includes a fourth driving member 401, an air blowing pipe 402, an air blowing pipe 403 and a fourth bellows 404; two left-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 to the air blowing pipe 402; the rear side of the air blowing pipe 402 is connected to a plurality of air blowing pipes 403; the air blowing pipe 402 is connected to the fourth bellows 404; the fourth bellows 404 is connected to the air storage box 308.

[0031] A sliding door 2001 is provided at the rear side of the protective cover 2 to facilitate the staff to clean the dust dropped on the workbench 1.

[0032] 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 driving member 401 is controlled to drive the blowing pipe 402 and the blowing pipe 403 to move downward, and the fourth bellows 404 is adaptively movable to avoid the staff from placing the polycarbonate plate 3. When 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 air storage box 308 is controlled to blow the hot air backward from the fourth bellows 404, the blowing pipe 402 and the blowing pipe 403. At the same time, the fourth driving member 401 drives the blowing pipe 402 and the blowing pipe 403 to move up and reset first, and then move up and down reciprocatingly, so that the hot air is blown to the upper and lower surfaces of the polycarbonate plate 3, so that the surface of the polycarbonate plate 3 is The dust moves backwards under the action of the airflow and then falls onto the workbench 1, thereby cleaning the dust on the surface of the polycarbonate plate 3 to avoid dust adhering to the surface of the polycarbonate plate 3, which may lead to the appearance of gray spots on the surface of the polycarbonate plate 3 after the subsequent hot pressing, affecting the quality of the polycarbonate plate 3. In addition, since the airflow used for cleaning is hot air, the polycarbonate plate 3 can also be preheated during cleaning, which is beneficial to the uniform softening of the polycarbonate plate 3 after subsequent heating. It should be noted that when the polycarbonate plate 3 is heated and softened by the electric heating wire 204, the pump in the air storage box 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 on the rear side of the protective cover 2 to clean the dust dropped on the workbench 1.

[0033] Except for the blowing pipe 403 on the blowing pipe 402 which is directly opposite to the center of the polycarbonate plate 3, the other blowing pipes 403 are all inclined toward the center of the polycarbonate plate 3; when the hot air is blown toward the polycarbonate plate 3 along the blowing pipe 403, the hot air blown out from the left and right blowing pipes 403 is gathered toward the center on the polycarbonate plate 3, and then blown backward by the blowing pipe 403 which is directly opposite to the center of the polycarbonate plate 3, so that the hot air carries dust away from parts such as the connecting tube 6, prevents a large amount of dust from adhering to parts such as the connecting tube 6, and reduces the cleaning cycle of parts such as the connecting tube 6.

[0034] The side of each blowing pipe 403 close to the polycarbonate plate 3 is opened to increase the coverage area of ​​the polycarbonate plate 3 surface by the airflow blown out from the blowing pipe 403, thereby improving the cleaning effect of the airflow on the dust on the surface of the polycarbonate plate 3.

[0035] The above is a detailed introduction to the present application. Specific examples are used in this article to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method of the present application and its core idea. At the same time, for general technical personnel in this field, according to the idea of ​​the present application, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
