The bracket 1 is provided with a second conveying unit 6 for conveying the paper core 12. The bracket 1 is provided with a first coating device 7 for applying adhesive to one side of the paper core 12 at the second conveying unit 6, so that when the mounting rod 4 moves to the second conveying unit 6, the paper core 12 is fixed on the outer peripheral surface of the first paper panel 11 in a cylindrical shape by rotating the mounting rod 4. The bracket 1 is provided with a third conveying unit 9 for moving the second paper panel 13. The bracket 1 is provided with a second coating device 7 for applying adhesive to the other side of the paper core 12 between the second conveying unit 6 and the third conveying unit 9. The wiping device 8 forms a structure in which when the mounting rod 4 moves to the third conveying unit 9, the second paper panel 13 is fixed to the outer peripheral surface of the paper core 12 in a cylindrical shape by the rotation of the mounting rod 4. During production, the first paper panel 11 is moved to a mounting rod 4 by the first conveying unit. The first paper panel 11 is fixed to the side surface of the mounting rod 4 in a cylindrical shape by the rotation of the fixing unit and the mounting rod 4. The mounting rod 4 is moved to the second conveying unit 6 by the rotation of the mounting plate 2. The adhesive is applied to the paper core 12 on the second conveying unit 6 by the first smearing device 7. The paper core 12 is adhered and fixed to the outer peripheral surface of the first paper panel 11 in a cylindrical shape by the rotation of the mounting rod 4. Continue to rotate the mounting disk 2 so that the mounting rod 4 reaches the second coating device 8. The mounting rod 4 rotates to apply adhesive to the outer circumferential surface of the cylindrical paper core 12. Then rotate the mounting disk 2 so that the mounting rod 4 reaches the third conveying unit 9. Through the rotation of the mounting rod 4, the second paper panel 13 is adhered and fixed to the outer circumferential surface of the paper core 12 in a cylindrical shape, thus completing the production of the cylindrical corrugated cardboard. During the entire production process, the lengths of the first paper panel 11, the paper core 12, and the second paper panel 13 are determined according to the circumference of each part of the cylindrical corrugated cardboard, and the cylindrical corrugated cardboard is directly formed. In addition, the entire cylindrical corrugated cardboard does not require extra corrugated paper to assist in the bonding and fixing of each part, thus saving raw materials.

[0028] In one embodiment, the joints of the first paper panel 11, the paper core 12, and the second paper panel 13 on each mounting rod 4 do not contact each other. Figure 8As shown, on the same mounting rod 4, the connection of the first paper panel 11, the connection of the paper core 12 and the connection of the second paper panel 13 are located at different positions, thereby separating the connections of the various parts of the cylindrical corrugated cardboard, effectively ensuring the compressive resistance of the entire finished product at each connection.

[0029] In one embodiment, the joints of the first paper panel 11, the paper core 12, and the second paper panel 13 on each mounting rod 4 are serrated, which facilitates the connection of the cylindrical corrugated cardboard parts and effectively ensures the compressive strength of the entire finished product at each joint.

[0030] In one embodiment, the mounting rods 4 are evenly distributed in a ring shape around the rotation axis of the mounting plate 2, so that the mounting rods 4 can be operated synchronously at each conveying unit. The number of the mounting rods 4 is a suitable number such as eight or ten.

[0031] In one embodiment, the first conveying unit includes an inclined plate 5.1, the upper surface of the inclined plate 5.1 is parallel to the rotation axis of the mounting plate 2, and the inclined plate 5.1 is fixedly connected to the bracket 1, wherein the inclined plate 5.1 and the bracket 1 are an integral structure, and can also be fixed by welding bolts. The bracket 1 is rotatably connected to the first roller 5.2 and the second roller 5.3 on the upper side of the inclined plate 5.1, and the first roller 5.2 and the second roller 5.3 are located on both sides of the first paper panel 11. The bracket 1 is installed on the inclined plate 5.1 on the lower side of the first roller 5.2 with a first cutting device 5.4 for cutting the first paper panel 11, wherein the first roller 5.2 and the second roller 5.3 are connected to the drive motor, and each drive motor is fixed to the bracket 1 with bolts. The first roller 5.2 and the second roller 5.3 cooperate to make the first paper panel 11 move downward. When the lower end of the first paper panel 11 moves to the mounting rod 4 to be matched, the lower end of the first paper panel 11 is fixed to the mounting rod 4 through the fixing unit, and the mounting rod 4 rotates so that the first paper panel 11 is rolled on the mounting rod 4. In this process, the first paper panel 11 is cut into a length equal to or slightly larger than the circumference of the side surface of the mounting rod 4 by the first cutting device 5.4. When the mounting rod 4 rotates one circle, the first paper panel 11 is cut into a length equal to or slightly larger than the circumference of the side surface of the mounting rod 4. The upper end of the first paper panel 11 is fixed to the mounting rod 4 through a fixing unit, so that the first paper panel 11 is fixed on the mounting rod 4 in a cylindrical shape, thereby forming a structure in which when the mounting rod 4 moves to the first conveying unit, the first paper panel 11 is fixed to the side surface of the mounting rod 4 in a cylindrical shape by the rotation of the mounting rod 4. The structure and principle of the third conveying unit 9 are the same as those of the first conveying unit. Through the cooperation of each roller, the second paper panel 13 moves downward. When the lower end of the second paper panel 13 moves to the mounting rod 4 to be matched, the adhesive applied on the paper core 12 makes the lower end of the second paper panel 13 and the paper core 12 adhere to each other. 12 is bonded and fixed, and the mounting rod 4 rotates so that the second paper panel 13 is rolled on the paper core 12. During this process, the second paper panel 13 is cut into a suitable length by the first cutting device 5.4. When the mounting rod 4 rotates one circle, the cut second paper panel 13 is bonded and fixed to the paper core 12 in a cylindrical shape, thereby forming a structure in which when the mounting rod 4 moves to the third conveying unit 9, the second paper panel 13 is fixed to the outer peripheral surface of the paper core 12 in a cylindrical shape through the rotation of the mounting rod 4. In the production of the existing technology, each paper panel and paper core 12 will be heated and softened to facilitate the bending of each paper panel, thereby forming a cylindrical structure.

[0032] In one embodiment, the minimum distance between the upper surface of the inclined plate 5.1 and the rotation axis of the mounting disk 2 is the sum of the maximum distance between the mounting rod 4 and the rotation axis of the mounting disk 2 and the thickness of the first paper panel 11. The distance between the first cutting device 5.4 and the foot of the perpendicular from the rotation axis of the mounting disk 2 to the upper surface of the inclined plate 5.1 is less than the circumference of the side surface of the mounting rod 4, thereby facilitating the cutting of the first paper panel 11 and its winding onto the mounting rod 4. At the third conveying unit 9, the minimum distance between the upper surface of the inclined plate 5.1 and the rotation axis of the mounting disk 2 is the sum of the maximum distance between the mounting rod 4 and the rotation axis of the mounting disk 2 and the thickness of the cylindrical corrugated cardboard. The distance between the first cutting device 5.4 and the foot of the perpendicular from the rotation axis of the mounting disk 2 to the upper surface of the inclined plate 5.1 is less than the circumference of the outer peripheral surface of the cylindrical paper core 12, thereby facilitating the cutting of the second paper panel 13 and its winding onto the paper core 12.

[0033] In one embodiment, the second conveying unit 6 includes a first embossing roller 6.1 and a second embossing roller 6.2 that cooperate with the embossed paper core 12 to form a wavy structure. The first embossing roller 6.1 and the second embossing roller 6.2 are rotatably connected to a bracket 1. A third embossing roller 6.3 that cooperates with the first embossing roller 6.1 is rotatably connected to the bracket 1. The bracket 1 is mounted on the third embossing roller 6.3 with a second cutting device 6.4 for cutting the paper core 12 on the third embossing roller 6.3. The third embossing roller 6.3 is provided with a cutting groove 6.5 that cooperates with the second cutting device 6.4. The third embossing roller 6.3 is provided with suction holes 6.6 on both sides of the cutting groove 6.5 for sucking and fixing the paper core 12. The suction holes 6.6 are connected to a negative pressure pump. By controlling this The operation of the negative pressure pump causes the third embossing roller 6.3 to adsorb and fix the paper core 12 through the suction hole 6.6. The bracket 1 is installed with the first coating device 7 at the third embossing roller 6.3, forming a structure in which the paper core 12 is molded by the first embossing roller 6.1 and the second embossing roller 6.2 and then fixed to the third embossing roller 6.3. Driven by the third embossing roller 6.3, the paper core 12 passes through the second cutting device 6.4 and the first coating device 7 in sequence and then reaches the mounting rod 4. The first embossing roller 6.1 and the second embossing roller 6.2 are identical and rotate synchronously. The first embossing roller 6.1 and the second embossing roller 6.2 mold the paper core 12 through the teeth on the outer surface, so that the paper core 12 forms a wavy structure. The first embossing roller 6.1 and the third embossing roller 6.3 are driven by the third embossing roller 6.3. 6.3 has the same module, and the third embossing roller 6.3 can also have the same structure as the first embossing roller 6.1. The first embossing roller 6.1, the second embossing roller 6.2, and the third embossing roller 6.3 are all connected to the drive motor, and each drive motor is bolted to the bracket 1. After the paper core 12 is embossed by the first embossing roller 6.1 and the second embossing roller 6.2, it is fixed to the third embossing roller 6.3 through the suction hole 6.6. As the third embossing roller 6.3 rotates, the paper core 12 first passes through the second cutting device 6.4 for cutting, and passes through the suction hole 6.6 without affecting the fixing of the cut paper core 12 to the third embossing roller 6.3. Then, the first coating device 7 applies adhesive to one side of the paper core 12, and then the paper core 12 reaches the mounting rod 4 to be matched. In this way, the paper core 12 is molded by the first molding roller 6.1 and the second molding roller 6.2 and then fixed to the third molding roller 6.3. Driven by the third molding roller 6.3, the paper core 12 passes through the second cutting device 6.4 and the first coating device 7 in sequence and reaches the mounting rod 4. At the mounting rod 4 to be matched, the paper core 12 is fixed to the first paper panel 11 on the mounting rod 4 by an adhesive. Through the rotation of this mounting rod 4, the cut paper core 12 is rolled on the first paper panel 11 in a cylindrical shape and bonded and fixed to the first paper panel 11. In this way, when the mounting rod 4 moves to the second conveying unit 6, the paper core 12 is fixed to the outer peripheral surface of the first paper panel 11 in a cylindrical shape through the rotation of the mounting rod 4.

[0034] In one embodiment, the fixing unit includes through holes 10 opened on the side surface of the mounting rod 4. The through holes 10 are arranged circumferentially along the mounting rod 4 and distributed axially along the mounting rod 4. The through holes 10 are connected to the negative pressure pump through a channel. There are two rows of through holes 10. Through the operation of this negative pressure pump, the mounting rod 4 and the first paper panel 11 are controlled to be adsorbed and fixed.

[0035] In one embodiment, the minimum distance between the first conveying unit, the second conveying unit 6, the third conveying unit 9, the first coating device 7, the second coating device 8 and the rotation axis of the mounting disk 2 is greater than the maximum distance between the mounting rod 4 and the rotation axis of the mounting disk 2, so that it does not affect the rotation of the mounting disk 2 and the mounting rod 4.

[0036] In one embodiment, after the cylindrical corrugated cardboard is manufactured, the fixing unit is first stopped, and then the cylindrical corrugated cardboard is removed from the mounting rod 4 by a clamp or other suitable device.

[0037] In one embodiment, the first coating device 7 and the second coating device 8 are suitable devices such as glue coating machines, and the first cutting device 5.4 and the second cutting device 6.4 are suitable devices such as cutting machines.

[0038] The present invention has been described in detail above by way of specific embodiments and examples, but these do not constitute limitations of the present invention. Without departing from the principles of the present invention, those skilled in the art may make many variations and improvements, which should also be considered within the scope of protection of the present invention.
