[0027] In this embodiment, when cooling the PC endurance plate, the PC endurance plate is placed between the first lower material guiding roller 32 and the first upper material guiding roller 33.

Embodiment 2

[0028] The difference between this embodiment and Embodiment 1 is that: the PC endurance plate cooling mechanism 5 includes a temperature sensor 51, a heat-conducting copper plate 52, a second U-shaped tube 53, a second solenoid valve 54, an air outlet pipe 55, a control component 56, a first solenoid valve 57, an air inlet pipe 58, a first U-shaped tube 59 and a cavity 510. Cavities 510 are opened at both the upper and lower ends inside the cooling box 4. A temperature sensor 51 is arranged inside the cavity 510. A heat-conducting copper plate 52 is arranged inside the cavity 510 near the feeding slot 6. A first U-shaped tube 59 is arranged on one side of the cooling box 4. The other end of the first U-shaped tube 59 is provided with an air inlet pipe 58. A first solenoid valve 57 is arranged on the side of the air inlet pipe 58. A second U-shaped tube 53 is arranged on the other side of the cooling box 4. The other end of the second U-shaped tube 53 is provided with an air outlet pipe 55. A second solenoid valve 54 is arranged on the side of the air outlet pipe 55. A control component 56 is arranged on the side of the U-shaped frame 1 near the first solenoid valve 57.

[0029] With the above technical solution, the first solenoid valve 57 is opened, and cold air is sent into the first U-shaped tube 59 through the air inlet pipe 58 and enters the cavity 510 inside the cooling box 4. Through the setting of the heat-conducting copper plate 52, heat transfer and absorption can be carried out on the upper and lower surfaces of the PC endurance plate, thereby effectively cooling the PC endurance plate. Then, the temperature sensor 51 monitors the cold air in the cavity 510. When the temperature of the cold air in the cavity 510 is too high, at this time, the temperature sensor 51 transmits a signal to the control component 56, and the control component 56 can automatically control the second solenoid valve 54 to close and the first solenoid valve 57 to open. At this time, the cold air in the cavity 510 can be replaced.

[0030] Specifically, the control component 56 includes a relay 561, a control box 562, a first partition 563, a door panel 564, a handle 565, a pin shaft 566, a second partition 567, a controller 568 and a heat dissipation slot 569. A control box 562 is arranged on the side of the U-shaped frame 1 near the first solenoid valve 57. A door panel 564 is arranged on the side of the control box 562. The control box 562 and the door panel 564 are rotatably connected through the pin shaft 566. A handle 565 is arranged at the side edge of the door panel 564. Heat dissipation slots 569 are opened on the other two sides of the control box 562. A second partition 567 is arranged at the lower end inside the control box 562. A controller 568 is arranged at the upper end of the second partition 567. A first partition 563 is arranged at the upper end inside the control box 562. A relay 561 is arranged at the upper end of the first partition 563.

[0031] With the above technical solution, the door panel 564 is driven by the handle 565 to be opened through the pin shaft 566. At this time, the relay 561 and the controller 568 at the upper ends of the first partition 563 and the second partition 567 can be overhauled and used.

[0032] The temperature sensor 51, the second solenoid valve 54, the first solenoid valve 57, the relay 561 and the controller 568 are all electrically connected by wires. By adopting this technical solution, the setting of this structure can ensure the normal operation of the device.

[0033] When this embodiment is in use, the first solenoid valve 57 is opened, and cold air is sent into the first U-shaped tube 59 through the intake pipe 58 and enters the cavity 510 inside the cooling box 4. Through the setting of the heat-conducting copper plate 52, heat transfer and absorption can be carried out on the upper and lower surfaces of the PC endurance plate, thereby effectively cooling the PC endurance plate. Then, the temperature sensor 51 monitors the cold air in the cavity 510. When the temperature of the cold air in the cavity 510 is too high, at this time, the temperature sensor 51 transmits a signal to the controller 568. After receiving the signal, the controller 568 controls the relay 561 to disconnect, and the relay 561 can automatically control the second solenoid valve 54 to close and the first solenoid valve 57 to open. At this time, the cold air in the cavity 510 can be replaced.

[0034] The temperature sensor 51 in the present invention is a publicly known technology, and the selected model is PT100.

[0035] The controller 568 in the present invention is a publicly known technology, and the selected model is Siemens S7-200.

[0036] The relay 561 in the present invention is a publicly known technology, and the selected model is Omega G2R-1A-E 5VDC.

[0038] Working principle of the present invention: When cooling the PC endurance plate, place the PC endurance plate between the lower material guiding roller 1 (32) and the upper material guiding roller 1 (33), turn on the motor (31). The motor (31) drives the rotation of the first rotating shaft (36) through the output end. The rotation of the first rotating shaft (36) drives the rotation of the lower material guiding roller 1 (32). The rotation of the first rotating shaft (36) drives the rotation of the driving gear (341). The rotation of the driving gear (341) drives the rotation of the driven gear (342). The rotation of the driven gear (342) drives the rotation of the second rotating shaft (35). The rotation of the second rotating shaft (35) drives the rotation of the upper material guiding roller 1 (33), thereby feeding the PC endurance plate into the feeding groove (6) for cooling. At the same time, the rotation of the first rotating shaft (36) drives the rotation of the first rotating gear (371). The rotation of the first rotating gear (371) drives the rotation of the synchronous belt (372). The rotation of the synchronous belt (372) drives the rotation of the second rotating gear (373). The rotation of the second rotating gear (373) drives the rotation of the third rotating shaft (310). The rotation of the third rotating shaft (310) can drive the rotation of the lower material guiding roller 2 (39) and the lower material guiding roller 2 (38), thereby automatically discharging the cooled PC endurance plate from the inside of the feeding groove (6). Open the first solenoid valve (57), send the cold air into the first U-shaped tube (59) through the air inlet pipe (58), and enter the internal cavity (510) of the cooling box (4). Through the arrangement of the heat conduction copper plate (52), heat transfer and absorption can be carried out on the upper and lower surfaces of the PC endurance plate, thereby effectively cooling the PC endurance plate. Then, monitor the cold air in the cavity (510) through the temperature sensor (51). When the temperature of the cold air in the cavity (510) is too high, at this time, the temperature sensor (51) transmits a signal to the controller (568). After receiving the signal, the controller (568) controls the relay (561) to disconnect. The relay (561) can automatically control the second solenoid valve (54) to close and the first solenoid valve (57) to open. At this time, the cold air in the cavity (510) can be replaced.
