The same pressure roller 14 is rotatably connected between the inner walls of the two sides of the U-shaped seat 13. Multiple second electric heating tubes 15 are embedded on both sides of the pressure roller 14. The first motor 17 drives the rectangular seat 4 to move through the double threaded screw 3. The rectangular seat 4 drives the clamping plate 7 to move and fix the corrugated paper. The first electric heating tube 8 heats the placement plate 5, so that the heat of the placement plate 5 is distributed on the corrugated paper. The electric telescopic rod 12 is started to drive the pressure roller 14 to move downward and contact the top of the corrugated paper. The second motor 19 is started, so that the connecting seat 11 drives the pressure roller 14 to move and rotate. The pressure roller 14 performs pressing and heating operations on the corrugated paper, so that the glue applied in the corrugated paperboard is heated. The corrugated paper is pressed and heated at the same time. During use, it is convenient to effectively fix the paperboard and can perform good bonding work on the corrugated paperboard. At the same time, it is convenient to perform uniform heating operations on the paperboard, thus improving the quality of the produced corrugated paperboard.

[0020] In this embodiment, specifically: two first square rods 16 are fixedly connected between the two side plates 2 that are close to each other, and the rectangular seat 4 is slidably sleeved on the outside of the two first square rods 16;

[0021] In this embodiment, specifically: the placement plate 5 is fixedly sleeved on the outside of the two first square rods 16, and the right side of one of the side plates 2 on the right side is fixedly connected to the first motor 17;

[0022] In this embodiment, specifically: the output shaft end of the first motor 17 is fixedly connected to the right end of the double threaded screw 3, and two second square rods 18 are fixedly connected to the front side of the U-shaped plate 9;

[0023] In this embodiment, specifically: the connecting seat 11 is slidably sleeved on the outside of the two second square rods 18, and the rear side of the U-shaped plate 9 is fixedly connected to the second motor 19;

[0024] In this embodiment, specifically: the output shaft end of the second motor 19 is fixedly connected to the rear end of the first screw 10, and the front end of the first screw 10 is fixedly connected to a limit block;

[0025] In this embodiment, specifically: a storage battery 20 is fixedly connected to the rear side of the U-shaped plate 9, and the storage battery 20 is electrically connected to the first electric heating tube 8 and the second electric heating tube 15 through a conduction wire. Support legs 21 are fixedly connected to the four bottom corners of the horizontal plate 1.

[0026] In operation, this invention works as follows: Corrugated paper is placed on top of the placement plate 5. Then, the first motor 17 is started, driving the double-threaded screw 3 to rotate. The rotation of the double-threaded screw 3 causes the rectangular seat 4 to slide outside the two first square rods 16. The rectangular seat 4 moves the L-shaped rod 6, which in turn moves the corresponding clamping plate 7. The two clamping plates 7 move closer together and fix the corrugated paper. The battery 20 provides power to the first electric heating tube 8 and the second electric heating tube 15 via a conductive wire. The first and second electric heating tubes 8 and 15 are energized and heated. The first electric heating tube 8 heats the placement plate 5, distributing the heat from the placement plate 5 onto the corrugated paper for preliminary preheating. Then, the electric telescopic rod 12 is started, causing the pressure roller 14 to move downwards. The machine contacts the top of the corrugated paper and then starts the second motor 19 in the forward direction. The second motor 19 drives the first screw 10 to rotate, and the rotation of the first screw 10 drives the connecting seat 11 to move forward. The connecting seat 11 slides on the outside of the two second square rods 18. The connecting seat 11 drives the pressure roller 14 to move forward and rotate. Similarly, the second motor 19 is started in the reverse direction, causing the pressure roller 14 to move backward and rotate. The pressure roller 14 performs pressing and heating operations on the corrugated paper, which heats the adhesive applied to the corrugated paperboard. The corrugated paperboard is pressed and heated at the same time, thus completing the hot pressing and bonding of the corrugated paperboard. This constitutes a hot pressing and bonding machine for paperboard production. During use, it is convenient to effectively fix the paperboard, can perform good bonding of the corrugated paperboard, and facilitates uniform heating of the paperboard, thereby improving the quality of the produced corrugated paperboard.
