[0026] Reference Figure 3 The hot pressing roller 203 includes a hollow roller 2031 rotatably mounted on the support plate 201. A temperature sensor 2033 and a heater 2032 are installed on the inner side of the hollow roller 2031. The temperature of the hot pressing roller 203 is accurately controlled by the temperature sensor 2033 and the heater 2032 to keep the hot pressing temperature within a suitable threshold. A covering layer 2034 is installed on the hollow roller 2031. Flexible extrusion is performed through the covering layer 2034 to prevent damage to the box plate.

[0027] Reference Figure 2The two adjacent cold press rollers 204 are connected by a guide pipe 4, the cold press roller 204 close to the hot press roller 203 is connected to the hollow roller 2021 by a guide pipe 5, and the hollow roller 2021 and the cold press roller 204 away from the hot press roller 203 are connected to the external cooling water circulation supply equipment through a connecting pipe 6, so that the water temperature from the cold press roller 204 to the hollow roller 2021 is gradually increased, reducing the power consumption and time required for the hot press roller 203 to heat the water on the drying box plate to improve the power.

[0028] Reference Figure 3 The hollow roller 1 2021, the hollow roller 2 2031 and the cold pressing roller 204 are driven by a chain transmission unit 8, wherein one of the chain transmission units 8 is connected to an external power device to realize synchronous rotation of the moistening roller 202, the hot pressing roller 203 and the cold pressing roller 204 to transport the box plate.

[0029] Reference Figure 2 , connecting seats 7 are installed at both ends of the hollow roller 1 2021, the hollow roller 2 2031 and the cold pressing roller 204, and mechanical seals are installed on the connecting surfaces of the hollow roller 1 2021, the hollow roller 2 2031, the cold pressing roller 204 and the connecting seat 7, and the guide tube 4, the conducting tube 5, the chain transmission unit 8, the heater 2032 and the temperature sensor 2033 are all installed on the connecting seat 7 to prevent the wetting roller 202, the hot pressing roller 203 and the cold pressing roller 204 from rotating and affecting the normal operation of the guide tube 4, the conducting tube 5, the chain transmission unit 8, the heater 2032 and the temperature sensor 2033.

[0030] The implementation principle of a packaging press according to an embodiment of the present application is as follows: when in use, an external power device is started, and the hollow roller 1 2021, the hollow roller 2031, and the cold pressing roller 204 are driven to start rotating synchronously through the chain transmission unit 8. The box board to be packaged enters from one end of the press, and first passes through the wetting roller 202 for wetting treatment on the upper and lower sides. At this time, 2021 rotates, and the sponge layer 2022 thereon is wetted with water in advance, so the box board is wetted through the water seepage holes thereon. The wetted box board continues to be transported forward and enters the hot pressing area. The box board passes between the hot pressing rollers 203, and the hot pressing rollers The heater 2032 in 2031 heats the roller body, and the temperature sensor 2033 monitors the temperature in real time to ensure that the hot pressing is carried out within the appropriate temperature range. The coating layer 2034 flexibly extrude the box plate, so that the box plate is quickly dried and shaped under the action of heat. The box plate after hot pressing and shaping continues to move forward and enters the cold pressing area. Between the cold pressing rollers 204, the box plate is further shaped and the possible stress is eliminated to prevent secondary bending. The water flow between the cold pressing rollers is gradually heated up through the guide pipe 4 and the conduction pipe 5 to reduce power consumption. After completing the above steps, the box plate is output from the other end of the press.
