[0001] The application belongs to the technical field of paperboard and paper tube production and processing, and particularly relates to a gluing equipment for paperboard and paper tube production and processing. BACKGROUND

[0002] In the production and processing of paperboard and paper tubes, gluing is one of the key process steps, and its quality directly affects the composite strength, durability and application performance of the final product. At present, the industry generally uses automatic gluing equipment to process single-sided gluing of paperboard to meet the conventional production needs such as paper box compounding and paper tube winding.

[0003] The existing gluing equipment cannot meet the mechanical properties and durability requirements of high-performance paper products in the production and processing of paperboard and paper tubes. For example, in the production process of certain industrial packaging, heavy paper tubes and high-end paper-based composite materials, double-sided gluing of paperboard is required to enhance the interlayer bonding force and improve the overall structural stability. However, the single-sided gluing equipment cannot directly realize this function, and production enterprises usually need to purchase special double-sided gluing equipment or indirectly realize double-sided gluing through multiple coating processes, which not only increases the equipment procurement cost but also leads to the problem of reduced production efficiency of the production line.

[0004] Therefore, the application provides a gluing equipment for paperboard and paper tube production and processing to solve the above problems. SUMMARY

The semi-annular groove 572 is formed... On one side of the inner surface of the first drive gear 53, the movable rod 573, on the side away from the locking block 571, extends into the support cylinder 56 and connects to the oblique cut block 574. The oblique cut block 574 is sleeved on the surface of the guide rod 575 and can move on the surface of the guide rod 575. The guide rod 575 and the spring 576 are fixedly connected to the support cylinder 56. The spring 576 is sleeved on the surface of the guide rod 575.

The oblique cutting block 574 is pushed by the compression ball 577, causing the movable rod 573 to move. The guide rod 575 guides the direction of movement of the oblique cutting block 574, ensuring accurate action. The spring 576 provides a restoring force, keeping the locking block 571 unlocked without external force. The compression ball 577 is pushed by the threaded rod 578, compressing the oblique cutting block 574. A third cylinder 6 is fixedly connected to one side of the second vertical plate 55. A plug rod 7 is fixedly connected to the output end of the third cylinder 6. Insertion holes for the plug rod 7 are provided at the top and bottom of one side of the second support plate 48. The third cylinder 6 pushes the plug rod 7 into or out of the insertion hole, locking... The second support plate 48 is fixed or released. A horizontal plate 8 is fixedly connected to one side of the glue tank 2. A fourth cylinder 9 is fixedly connected to the bottom of the horizontal plate 8. The bottom of the fourth cylinder 9 is fixedly connected to the base 1. The horizontal plate 8 and the fourth cylinder 9 adjust the height of the glue tank 2 to facilitate cleaning the inside of the glue tank 2. A guide frame is fixedly connected to the top of the base 1. A groove is opened on the top of the guide frame. A guide roller is rotatably connected to one side of the groove. The guide roller is rotatably connected to the side of the groove through a bearing. The guide frame and the guide roller guide the cardboard into the glue application area to ensure the accurate travel path of the cardboard. A bracket is fixedly connected to one side of the motor 45. The bracket is fixedly connected to the first vertical plate 46. An installation hole is opened on the top of the base 1.

[0037] The working principle of this invention is as follows: The cardboard is guided into the gluing area by the guide frame. The motor 45 starts, driving the lower glue roller 3 to rotate clockwise, dipping it into the glue tank 2 to apply glue to the lower surface of the cardboard. At the same time, the hollow rod 52 is driven to rotate through the fixed rod 51 and the synchronous belt transmission system, which in turn drives the conveyor roller 44 to rotate counterclockwise through the first drive gear 53 and the second drive gear 54, realizing continuous conveying and single-sided gluing of the cardboard.

[0038] When switching to double-sided adhesive application, the operator turns the handwheel 579, which moves the extrusion ball 577 via the threaded rod 578. The spring 576 drives the oblique cutting block 574 to move, causing the locking block 571 to disengage from the semi-annular groove 572 of the first drive gear 53, thus releasing the mechanical lock. Simultaneously, the third cylinder 6 retracts the insertion rod 7, and the second cylinder 4117 retracts the limiting plate 4118, releasing the limit on the first limiting gear 4115. The first cylinder 4113 drives the limiting rod 4114 to insert into the limiting groove 4116. The motor 45 continues to run, and through the cooperation of the synchronous pulley, synchronous belt, drive rod 4111, turntable 4112, first cylinder 4113, and limiting rod 4114, it drives the first limiting gear 4115 to rotate. This, in turn, through the second limiting gear 4119, drives the diverter pipe 41 and its first support plate 42, the adhesive roller 43, and the conveying roller 44 to rotate half a turn, causing the adhesive roller 43 to move downwards. During the flipping process, the first drive gear 53 and the second drive gear 54 remain engaged. As the first drive gear 53 is clamped, the gear flips simultaneously while maintaining engagement. After the flipping is complete, the insert rod 7 and the limiting plate 4118 reset, and the locking block 571 re-engages into the semi-annular slot 572, completing the state locking.

[0039] The glue pump 4104 starts, conveying glue from the glue tank 2 through the threaded telescopic tube 4106, the through pipe 4105, and the guide pipe 4103 to the distribution pipe 41. The glue is then evenly coated onto the surface of the top glue roller 43 via the spreading plate 49. The cardboard passes between the conveying roller 44 and the top glue roller 43. The clockwise rotating bottom glue roller 3 and the counterclockwise rotating top glue roller 43 apply glue to the lower and upper surfaces of the cardboard respectively and convey it, achieving efficient and uniform double-sided glue coating.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
