Description

Technical Field

[0001] This invention relates to the field of corrugated cardboard box production technology, specifically to a corrugated cardboard box gluing equipment and its operating method. Background Technology

[0002] Corrugated cardboard boxes are rigid paper packaging containers made of corrugated cardboard, primarily used to protect goods during transportation and warehousing. Their core functions are to provide cushioning and compression support, while also being lightweight, easy to process, and recyclable.

[0003] A search revealed a Chinese patent with application number "CN202510401453.3", which is specifically a corrugated cardboard box gluing device. This device relates to the technical field of corrugated cardboard box processing and includes a frame, a conveying mechanism, a cleaning mechanism, and a gluing mechanism. The conveying mechanism is mounted on the frame and used to convey the corrugated cardboard box. The cleaning mechanism is mounted on a flap on the frame and used to clean the areas on the corrugated cardboard box to be glued. The gluing mechanism is mounted on the flap and located behind the cleaning mechanism, and is used to apply glue to the cleaned areas of the corrugated cardboard box.

[0004] Corrugated cardboard boxes are typically formed by die-cutting and creasing corrugated cardboard and then gluing it together. Gluing is a crucial step in the final forming process. In gluing, the flat cardboard (face paper) must be accurately adhered to the glued corrugated cardboard, using adhesive to firmly bond the two. However, currently, most gluing processes still rely on manual labor to place the flat cardboard onto the corrugated cardboard for positioning and adhesion. This manual operation not only increases the number of steps and labor intensity for workers but also results in low production efficiency, making it difficult to meet the demands of large-scale production.

[0005] Therefore, this invention proposes a corrugated cardboard box gluing device and operating method to solve the aforementioned problems. Summary of the Invention

[0033] This invention provides the following technical solutions:

[0034] Example 1

[0035] Please see Figure 1 - Figure 6 A corrugated cardboard box gluing device includes a mounting frame 1, a conveyor belt 2 on the inner side of the mounting frame 1, an adhesive application unit 3 on the upper side of the mounting frame 1, two fixing plates 4 fixedly connected to the upper side of the mounting frame 1 and the right side of the adhesive application unit 3, a top plate 5 fixedly connected to the upper side of the fixing plates 4, a discharge hole 8 in the middle of the top plate 5, a correction unit 6 on the upper side of the top plate 5, a padding unit 7 on the right side of the correction unit 6, the correction unit 6 including a top cylinder 61, the top cylinder 61 fixedly connected to the upper side of the top plate 5, and a side hole 63 on the right side of the top cylinder 61. The corrugated board is conveyed by the conveyor belt 2 and the adhesive application unit 3 performs an adhesive application operation on the corrugated board.

[0036] The padding unit 7 includes a material container 71, which is fixedly connected to the right side of the top cylinder 61. A material plate 74 is provided inside the material container 71. A rectangular hole 72 is opened on the right side of the material container 71. A bottom groove 76 is opened on the lower side of the material container 71. A baffle 75 is fixedly connected to the upper side of the top cylinder 61. A sliding rod 73 is fixedly connected to the right side of the top cylinder 61. A sliding cylinder 710 is slidably connected to the outer side of the sliding rod 73. A bottom rod 711 is fixedly connected to the lower side of the sliding cylinder 710. A movable block 712 is provided on the outer side of the bottom rod 711. A fixed connection is made to the upper side of the movable block 712. A sliding plate 713 is attached, with a lever 714 fixedly connected to its upper side. A rotating shaft 715 is rotatably connected to the rear side of a moving block 712. An L-shaped plate 716 is fixedly connected to the outer side of the rotating shaft 715. A vertical rod 717 is fixedly connected to the lower side of the L-shaped plate 716. A rotating block 718 is provided on the outer side of the vertical rod 717. A spring 719 is fixedly connected between the rotating block 718 and the L-shaped plate 716.

The moving block 712 is slidably connected to the base rod 711, and the rotating block 718 is slidably connected to the upright rod 717. The slide plate 713 is located below the material box 71. After the corrugated board is coated with glue, the motor 78 is started. The motor 78 drives the rotating rod 79 to rotate, the rotating rod 79 drives the rotating block 718 to rotate, the rotating block 718 drives the L-shaped plate 716 on the upright rod 717 to rotate, the L-shaped plate 716 drives the slide plate 713 on the moving block 712 to move to the left, and the slide plate 713 drives the lever 714 to move to the left, so that the lever... 714 moves at the bottom groove 76. The lever 714 drives the material plate 74 to move. When the material plate 74 moves to the leftmost end of the material box 71, during this process, the rotating block 718 slides along the upright 717, the moving block 712 descends, and the moving block 712 drives the lever 714 on the slide plate 713 to descend, so that the lever 714 separates from the material plate 74. Then the lever 714 moves to the right and repeats the above process, so that the material plates 74 are discharged one by one to the top cylinder 61, so that under the action of gravity, the material plates 74 fall onto the corrugated board after the glue is applied, and the bonding of the corrugated carton is completed.

[0037] A side frame 9 is fixedly connected to the right side of the fixed plate 4. A hydraulic cylinder 10 is fixedly connected to the upper side of the side frame 9. A bottom frame 11 is fixedly connected to the lower output end of the hydraulic cylinder 10. A pressure roller 12 is provided on the inner side of the bottom frame 11. When the material plate 74 is bonded to the corrugated plate, the hydraulic cylinder 10 is controlled to drive the bottom frame 11 to descend. The bottom frame 11 drives the pressure roller 12 to descend, so that the pressure roller 12 presses down on the material plate 74, which makes it easier for the corrugated plate and the material plate 74 to bond more tightly.

[0038] The glue application unit 3 includes a top frame 31, which is fixedly connected to the upper side of the mounting frame 1. A hydraulic cylinder 32 is fixedly connected to the upper side of the top frame 31. A lifting frame 33 is fixedly connected to the lower output end of the hydraulic cylinder 32.

A pump body 36 is fixedly connected to the upper side of the lifting frame 33. A delivery pipe 37 is fixedly connected between the pump body 36 and the connecting pipe 34. A glue tank 39 is fixedly connected to the outer side of the top frame 31. A fixing pipe 38 is fixedly connected between the glue tank 39 and the pump body 36. During glue application, the hydraulic cylinder 32 is controlled to drive the lifting frame 33 to descend. The lifting frame 33 drives the connecting pipe 34 to descend. The connecting pipe 34 drives the glue spraying heads 35 to descend. Then, the pump body 36 is activated. Under the action of the delivery pipe 37 and the fixing pipe 38, the glue spraying heads 35 spray glue onto the corrugated board, which is convenient for subsequent box gluing.

An electric push rod 614 that drives the U-shaped plate 613 to move is fixedly connected to the left side of the top cylinder 61. When the material plate 74 falls, the electric push rod 614 controls the U-shaped plate 613 to rise. The U-shaped plate 613 drives the guide block 612 to move. The guide block 612 drives the inclined plate 69 to rotate. The inclined plate 69 drives the moving plate 66 to move. The moving plate 66 drives the moving rod 65 to move. The moving rod 65 drives the correction plate 67 to move. The inclined plates 69 on the front and rear sides are symmetrically distributed so that the correction plates 67 on both sides are close to each other, which makes it convenient for the correction plates 67 to correct the material plate 74 and avoid the material plate 74 from shifting and affecting the bonding effect.

[0042] An operating method for a corrugated cardboard box gluing device includes the following steps:

[0043] S1. Place the corrugated board on the conveyor belt 2, and then the hydraulic cylinder 2 32 drives the glue spray head 35 to descend and apply glue to the corrugated board. Then the corrugated paper is conveyed to the bottom of the top plate 5.
