The first unwinding component 11 is fixedly connected to the lower forming frame 12, and the lower forming roller 121 is installed on the lower forming frame 12. It can be understood that the blank of the blanking plate enters the lower forming roller 121 from the first unwinding component 11, and the driving motor starts the lower forming roller 121 to rotate. This part of the technology is the existing technology and will not be described here. After that, the lower forming roller 121 presses a groove on the blank of the blanking plate to form a blanking plate, and at the same time drives the blanking plate to move like a polyurethane casting mechanism.

[0026] The polyurethane pouring mechanism is connected to the lower molding frame 12. Specifically, the polyurethane pouring mechanism includes: a low-pressure foaming machine 21, a pouring head 22 and a feeding pipe 23. The pouring head 22 is fixedly connected to the lower molding frame 12. The pouring head 22 is connected to the low-pressure foaming machine 21 through the feeding pipe 23. It can be understood that the low-pressure foaming machine 21 feeds the two raw materials into the pouring head 22 through the feeding pipe 23, and the polyurethane obtained after the two raw materials are mixed in the pouring head 22 is evenly poured onto the blanking plate below.

[0027] The upper forming mechanism 3 includes a second unwinding assembly 31, an upper forming frame 32 and an upper forming roller 321. The second unwinding assembly 31 and the upper forming frame 32 are fixedly connected above the lower forming frame 12. The upper forming roller 321 is installed on the upper forming frame 32. It can be understood that the loading plate blank enters the upper forming roller 321 of the upper forming mechanism 3 from the second unwinding assembly 31, and enters the forming and maturation device 4 under the drive of the upper forming roller 321, and is processed flat by the upper forming roller 321 to become a loading plate.

[0028] The forming and aging device 4 is arranged behind the lower forming mechanism 1, and the forming and aging device 4 includes a forming and aging frame 41 and a forming and aging roller 42, and the forming and aging roller 42 is installed on the forming and aging frame 41. It can be understood that the lower material plate poured with polyurethane enters the forming and aging device 4 under the drive of the lower forming mechanism 1, and the upper material plate is attached to the lower material plate poured with polyurethane. Under the extrusion of the forming and aging roller 42, the lower material plate, polyurethane, and upper material plate are bonded together to form a polyurethane composite plate, and the polyurethane composite plate is driven to enter the sawing mechanism 5 at the same time.

[0029] The sawing mechanism 5 is fixedly connected to the rear of the forming and maturing device 4. Specifically, the sawing mechanism 5 includes: a sawing frame 51 and a cutting saw 52. The sawing frame 51 is fixedly connected to the forming and maturing frame 41, and the cutting saw 52 is installed at the front end of the sawing frame 51.
