[0014] In order to make the purpose, technical solutions and beneficial effects of the present invention clearer, the preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings to facilitate understanding by technicians.

[0015] like Figure 1-4 As shown, the utility model provides a high-strength, impact-resistant, composite, and environmentally friendly corrugated paper production pressing device, comprising a frame 1 and two corrugating rollers 2; the corrugating rollers 2 have a gear-shaped cross-section, and are rotatably mounted at both ends on two side plates of the frame 1. The two corrugating rollers 2 are meshed with each other; a rotating shaft 3 is mounted on the ribs of the corrugating rollers 2, and the two ends of the rotating shaft 3 are rotatably mounted on bosses 4 provided at both ends of the ribs. When the utility model is in use, a cardboard passes between the two meshing corrugating rollers 2, and the cardboard is pressed into a corrugated shape under the meshing of the two corrugating rollers 2. When the corrugating rollers 2 press the cardboard, the rotating shaft 3 is mounted on the ribs of the corrugating rollers 2, so that when the corrugating rollers 2 press the cardboard, the rotating shaft 3 contacts the cardboard, causing the rotating shaft 3 to rotate as the cardboard is pressed, thereby reducing friction between the corrugating rollers 2 and the cardboard, making the pressing of the cardboard smoother, reducing resistance during the pressing of the cardboard, and improving the efficiency of the cardboard pressing.

[0016] The inner wall of the frame 1 is rotatably mounted with a glue roller 5 and a facial paper conveying roller 6; a glue tank 7 filled with starch glue is provided at the bottom of the frame 1; the glue roller 5 contacts the starch glue in the glue tank 7, and the glue roller 5 rotates to adhere the starch glue to the surface of the glue roller 5. The starch glue on the surface of the glue roller 5 contacts the flute peaks of the corrugated core paper 9 after being pressed by the corrugating roller 2; the facial paper 10 conveyed by the facial paper conveying roller 6 contacts the glued core paper 9. The corrugated core paper 9, which has been pressed into a corrugated shape by the corrugating roller 2, rotates with the corrugating roller 2, and the flute peaks of the core paper 9 contact the starch glue on the surface of the glue roller 5. The starch glue adheres to the flute peaks, and the core paper 9 and the facial paper 10 conveyed by the facial paper conveying roller 6 are pressed and adhered together to form a single-sided paper 10 corrugated board; the cardboard pressing and pasting of the facial paper 10 are completed continuously, which is conducive to improving the production efficiency of corrugated paper.

[0017] A glue control roller 8 is also rotatably mounted on the inner wall of the frame 1. The glue control roller 8 rotates in the opposite direction to the glue application roller 5, and the distance between the glue control roller 8 and the glue application roller 5 is 2-4 mm. The glue application roller 5 rotates to adhere the starch glue in the glue tank 7 to the surface of the glue application roller 5, thereby adhering the starch glue to the core paper 9. The glue control roller 8 rotates in the opposite direction to the glue application roller 5, scraping excess starch glue on the surface of the glue application roller 5 into the glue tank 7, thereby avoiding glue waste and preventing excessive glue from being applied to the core paper 9, which would extend the glue drying time and reduce the efficiency of corrugated paper production.

[0018] The side wall of the frame 1 is equipped with a motor 11 which is respectively connected to the corrugating roller 2, the gluing roller 5, the surface paper conveying roller 6 and the glue control roller 8. The motor 11 drives the corrugating roller 2, the gluing roller 5, the surface paper conveying roller 6 and the glue control roller 8 to rotate.

[0019] Working process:

[0020] When the utility model is in use, the cardboard passes between two mutually meshing corrugating rollers 2, and the cardboard is pressed into a corrugated shape under the meshing of the two corrugating rollers 2. When the corrugating rollers 2 press the cardboard, a rotating shaft 3 is installed on the convex strip of the corrugating rollers 2, so that when the corrugating rollers 2 press the cardboard, the rotating shaft 3 contacts the cardboard, and the rotating shaft 3 rotates with the pressing of the cardboard, thereby reducing the friction between the corrugating rollers 2 and the cardboard, making the pressing of the cardboard smoother, reducing the resistance during the pressing of the cardboard, and improving the efficiency of the cardboard pressing. The core paper 9 pressed into a wavy shape by the corrugating rollers 2 rotates with the corrugating rollers 2, and the flute peaks of the core paper 9 contact the starch glue on the surface of the glue roller 5, and the starch glue adheres to the flute peaks. The core paper 9 is pressed and pasted together with the surface paper 10 transmitted by the surface paper transmission roller 6 to form a single-sided paper 10 corrugated board.

[0021] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
