Description

Technical Field

[0001] This utility model relates to the field of inner box linerboard technology, specifically to an automatic gluing and positioning structure for inner box linerboard. Background Technology

[0002] Inner box linerboard, as a type of packaging material, is usually used for the internal packaging of products to protect them, enhance their grade, and increase their added value. There are many different types of materials for inner box linerboard, the most common of which are: white paper, coated paper, whiteboard paper, kraft paper, and specialty paper.

[0003] For example, the automatic box-making machine and process disclosed in patent CN113246532A have the following beneficial effects: 1. By compressing the sealing cover, the glue in the glue supply box can be squeezed into the pressure plate when the sealing cover is compressed, thereby quickly adjusting the glue content in the pressure plate. This ensures that a certain amount of glue is applied to the face paper when the pressure plate is pressed and glued with the face paper, so that the face paper can be stably bonded to the bottom and perimeter walls of the box, avoiding glue overflow due to excessive glue on the face paper or weak bonding due to insufficient glue on the face paper; 2. The motor drives the double-headed lead screw to rotate, thereby driving the two threaded cylinders to move in a direction away from each other. The angle between the upper and lower rotating rods located on both sides of the same threaded cylinder decreases, allowing for rapid adjustment of the distance between the upper and lower extrusion plates under the combined action of the two upper and two lower rotating rods. Furthermore, the upper extrusion plate remains parallel to the lower extrusion plate as it moves towards it, ensuring uniform glue extrusion across the pressure plate and consequently uniform glue application across the face paper, thus improving the adhesion between the face paper and the box body. 3. The torsion spring adjusts the force exerted by the scraper against the box's perimeter. As the box moves downwards, the scraper, under the torsion of the torsion spring, presses the face paper tightly against the box's perimeter, resulting in better adhesion. However, the aforementioned patent lacks a structure for positioning the face paper during gluing. If the face paper is not securely positioned during gluing, its position can easily shift unpredictably. This shift can easily cause wrinkles or air bubbles, damaging the flatness and aesthetics of the face paper and potentially affecting subsequent processing steps.

[0004] Therefore, there is an urgent need for an automatic glue-applying and positioning structure for the inner box linerboard to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide an automatic gluing and positioning structure for inner box face paper, which has the advantage of positioning the inner box face paper and solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic gluing and positioning structure for inner box linerboard, including a workbench, a gluing device fixedly connected to the top of the workbench, a conveying device provided on one side of the workbench, the conveying device being located at the bottom of the gluing device, and the inner box linerboard being provided on the top of the conveying device.

[0007] The power assembly includes a motor fixedly connected to the left side of the worktable.

Threaded blocks are threadedly connected to both sides of the surface of the threaded rod, and a connecting block is fixedly connected to the top of the threaded blocks.

[0008] The pressing assembly includes a movable frame fixedly connected to the top of the connecting block. Movable holes are provided on both sides of the movable frame. Movable rods are slidably connected to the inner cavities of the two movable holes. Both ends of the movable rods extend to the outside of the movable holes and are fixedly connected to pressure plates. Fixed plates are rotatably connected to both sides of the pressure plates. One side of the fixed plate is fixedly connected to the worktable. The fixed plate is compatible with the inner box liner.

[0009] Furthermore, as a preferred embodiment of this utility model, a support plate is fixedly connected to the bottom of the motor, and the right side of the support plate is fixedly connected to the workbench.

[0010] Furthermore, as a preferred embodiment of this utility model, sliding holes are provided on both sides of the top of the workbench, and the connecting block is located in the inner cavity of the sliding hole and is slidably connected to the sliding hole.

[0011] Furthermore, as a preferred embodiment of this utility model, a rubber block is fixedly connected to the bottom of the pressure plate, and the bottom of the rubber block is in contact with the inner box liner.

[0013] Furthermore, as a preferred embodiment of this invention, the threads on both sides of the threaded rod surface are arranged in opposite directions.

[0014] Beneficial effects: The technical solution of this application has the following advantages: This utility model has the advantage of positioning the inner box face paper. In actual use, by pressing the inner box face paper, a moderate pressure is applied to the inner box face paper, making it tightly adhere to the conveyor belt, effectively preventing displacement during gluing.

A gluing device 2 is fixedly connected to the top of the workbench 1. The gluing device 2 is existing technology, and its working principle is well known to those skilled in the art. A conveying device 3 is provided on one side of the workbench 1. The conveying device 3 is located at the bottom of the gluing device 2, and the inner box face paper 13 is provided on the top of the conveying device 3.

[0025] The power assembly includes a motor 4 fixedly connected to the left side of the worktable 1. The output shaft of the motor 4 passes through the inner cavity of the worktable 1 and is fixedly connected to a threaded rod 5. The threads on both sides of the surface of the threaded rod 5 are arranged in opposite directions. The right end of the threaded rod 5 is rotatably connected to the worktable 1. Threaded blocks 6 are threadedly connected to both sides of the surface of the threaded rod 5. A connecting block 7 is fixedly connected to the top of the threaded block 6.

[0026] The pressing assembly includes a movable frame 8 fixedly connected to the top of the connecting block 7. Movable holes 9 are provided on both sides of the movable frame 8. Movable rods 10 are slidably connected to the inner cavities of the two movable holes 9. Both ends of the movable rods 10 extend to the outside of the movable holes 9 and are fixedly connected to pressure plates 11. Fixed plates 12 are rotatably connected to both sides of the pressure plates 11. One side of the fixed plates 12 is fixedly connected to the workbench 1. The fixed plates 12 and the inner box paper 13 are compatible.

[0027] Specifically, a support plate 14 is fixedly connected to the bottom of the motor 4, and the right side of the support plate 14 is fixedly connected to the worktable 1.

[0028] In this embodiment, the support plate 14 serves to support and fix the motor 4, thereby improving the safety of the motor 4 during operation.

[0029] Specifically, sliding holes 15 are provided on both sides of the top of the workbench 1, and the connecting block 7 is located in the inner cavity of the sliding hole 15 and is slidably connected to the sliding hole 15.

[0030] In this embodiment: by setting the sliding hole 15, the connecting block 7 will slide in the inner cavity of the sliding hole 15 when it moves, thereby limiting and guiding the connecting block 7, thus preventing the threaded block 6 from rotating.

[0031] Specifically, a rubber block 16 is fixedly connected to the bottom of the pressure plate 11, and the bottom of the rubber block 16 is in contact with the inner box liner 13.

[0032] In this embodiment: by setting the rubber block 16, the rubber block 16 replaces the pressure plate 11 to contact the inner box paper 13, which improves the positioning effect and avoids damage to the inner box paper 13.

[0033] Specifically, a limiting plate 17 is fixedly connected to one side of the workbench 1. The limiting plate 17 is located in the inner cavity of the conveying device 3. Several rollers 18 are rotatably connected to the inner cavity of the limiting plate 17. The rollers 18 are used in conjunction with the conveying device 3.

[0034] In this embodiment: through the cooperation of the limiting plate 17 and the roller 18, when the pressure plate 11 drives the rubber block 16 to press the inner box paper 13 downward, the roller 18 is used to limit the belt, preventing the inner box paper 13 from moving downward under the pressing force of the rubber block 16, thereby effectively avoiding unnecessary deformation of the belt. At the same time, when the conveying device 3 is working, the belt can naturally drive the roller 18 to rotate in the inner cavity of the limiting plate 17, thereby ensuring that the operation process of the conveying device 3 is not disturbed.

[0035] The working principle and usage process of this utility model are as follows: In use, the inner box paper 13 is conveyed to the bottom of the gluing equipment 2 by the conveying device 3. Then, the motor 4 is started. The output shaft of the motor 4 drives the threaded rod 5 to rotate. When the threaded rod 5 rotates, it drives two threaded blocks 6 to move in opposite directions through the threads on its surface. The threaded blocks 6 drive the movable frame 8 to move through the transmission of the connecting block 7. At this time, the movable frame 8 pulls the movable rod 10 to move in the inner cavity of the movable hole 9. Under the transmission of the movable rod 10, the pressure plate 11 is driven to rotate around the intersection of the pressure plate 11 and the fixed plate 12. When the pressure plate 11 rotates, it drives the rubber block 16 to rotate downward. Thus, the inner box paper 13 is positioned by the rubber block 16. Then, the inner box paper 13 is glued by the gluing equipment 2, which can prevent the inner box paper 13 from shifting during the gluing process.
