During use, the box gluer usually stacks cardboards on a paper feed table, and then conveys the cardboards backward one by one to the next process through a conveyor belt on the paper feed table. There are two pushing mechanisms 20, which are respectively arranged on the table surfaces of the paper feed table on both sides of the conveyor belt, and push the side edges of the cardboards so that the cardboards stacked up and down can automatically fit, align and be regular, ensuring the accuracy of the position of the cardboards when they are conveyed to the subsequent process. The fixing assembly 40 fixes the pushing mechanism 20 at different positions, so that it can be adjusted according to cardboards of different models and sizes, and has strong adaptability.

[0029] Specifically, support columns 10 are provided on both sides of the paper feed table, and a rotating shaft 11 is rotatably provided between the two support columns 10. The axis direction of the rotating shaft 11 is perpendicular to the conveying direction of the conveyor belt of the paper feed table. A driving motor 12 is provided on one of the support columns 10, and the driving motor 12 drives the rotating shaft 11 to rotate. Long ring teeth 13 fixedly connected to the rotating shaft 11 are respectively sleeved at both ends of the rotating shaft 11, and the teeth on the long ring teeth 13 are arranged along the length direction of the rotating shaft 11. The rotation of the rotating shaft 11 drives the long ring teeth 13 to rotate.

[0030] The pushing mechanism 20 includes a first slide rail 21 arranged on the paper feeding table and having a length direction consistent with the axis direction of the rotating shaft 11. A sliding frame 22 is slidably arranged on the first slide rail 21, so that the sliding frame 22 can slide on the first slide rail 21. A rotating ring 23 arranged coaxially with the rotating shaft 11 is rotatably arranged on the sliding frame 22. A tooth groove is provided in the rotating ring 23 corresponding to the long ring teeth 13, so that when the rotating shaft 11 drives the long ring teeth 13 to rotate, the rotating ring 23 rotates with the rotating shaft 11. A first bevel gear 24 is coaxially arranged on the rotating ring 23, and a rotating shaft 25 with an axis direction perpendicular to the axis direction of the rotating shaft 11 is rotatably arranged on the sliding frame 22. A second bevel gear 26 is arranged on one end of the rotating shaft 25 adjacent to the rotating shaft 11. The second bevel gear 26 meshes with the first bevel gear 24. When the rotating ring 23 rotates, the first bevel gear 24 is driven to rotate, thereby driving the second bevel gear 26 and the rotating shaft 25 to rotate. A circular hole is provided in the first bevel gear 24 to allow the rotating shaft 11 and the long ring gear 13 to pass through.

[0031] The sliding frame 22 is provided with a mounting plate 30, on which a sliding rod 31 is slidably provided, whose rod core direction is perpendicular to the axis core direction of the rotating shaft 25. A pushing plate 32 is provided at one end of the sliding rod 31 away from the rotating shaft 25, and a push plate 33 is provided at one end close to the rotating shaft 25, so that the sliding rod 31, the pushing plate 32, and the push plate 33 move synchronously. A compression spring 34 is sleeved on the rod body of the sliding rod 31 located between the push plate 33 and the mounting plate 30, and a cam 27 is provided on the shaft body of the rotating shaft 25 located beside the push plate 33. The rotation of the rotating shaft 25 drives the cam 27 to rotate, so that the protruding part of the cam 27 pushes the push plate 33, and drives the sliding rod 31 and the pushing plate 32 to push the side of the cardboard, so that the cardboards stacked up and down can automatically fit and align. When pushing, the push plate 33 moves so that the compression spring 34 is compressed. After the protrusion of the cam 27 leaves the push plate 33, the compression spring 34 releases its elasticity so that the push plate 33, the slide bar 31, and the push plate 32 are reset. The sliding frame 22 slides on the first slide rail 21, so that the position of the push plate 32 can be adjusted according to different models and sizes of cardboards, with strong adaptability and more convenient use. When the sliding frame 22 slides, the tooth groove of the rotating ring 23 slides on the long ring teeth 13, so that the tooth groove always cooperates with the long ring teeth 13, so that after the sliding frame 22 moves, the rotating ring 23 can still obtain the rotation force from the rotating shaft 11. A plurality of sleeves 35 are arranged on the mounting plate 30, and a sliding rod 36 arranged parallel to the slide bar 31 is slidably arranged in the sleeve 35. One end of the sliding rod 36 is fixedly connected to the push plate 32, further improving the stability of the movement of the push plate 32.

The baffle 53 is located above the conveyor belt of the paper feeder. A mounting frame 54 is also provided between the two support columns 10. The driving assembly 60 is provided on the mounting frame 54 for driving the baffle 53 to slide, so that the distance between the bottom of the baffle 53 and the belt surface of the conveyor belt of the paper feeder can be adjusted according to the thickness of the paperboard, ensuring that the conveyor belt can only convey one paperboard at a time, and the adaptability is stronger.

[0034] The driving assembly 60 includes a threaded rod 61 rotatably disposed on the mounting frame 54 and arranged vertically, and a fixing block 62 is disposed on the baffle 53. The fixing block 62 is screwed with the threaded rod 61 through a threaded hole, so that when the threaded rod 61 rotates, the fixing block 62 is driven to move on the threaded rod 61, thereby driving the baffle 53 to move. A worm wheel 63 is disposed on the upper end of the threaded rod 61, and a worm 64 is rotatably disposed on the mounting frame 54. The worm 64 cooperates with the worm wheel 63. One end of the worm 64 passes through the support column 10 and is provided with a screwing handle 65. Screwing the screwing handle 65 drives the worm 64 to rotate, thereby driving the worm wheel 63 and the threaded rod 61 to rotate, so that the fixing block 62 moves up and down on the threaded rod 61, thereby driving the baffle 53 to slide on the second slide rail 52.
