Description

Technical Field

[0001] This utility model relates to the field of packaging paper creasing technology, specifically a roll-printed packaging paper creasing device. Background Technology

[0002] A creasing machine is a machine used to cut various sheet materials, such as cardboard, corrugated cardboard, plastics and leather. It is widely used in the printing, packaging, decoration and plastics industries. It is divided into manual creasing machines and automatic creasing machines, and the operating height is reasonably designed.

[0003] For example, the packaging paper creasing device with patent number CN221497290U uses a sliding rod to facilitate rapid adjustment of the blade spacing to meet different creasing requirements. It also uses a hydraulic rod to prevent the threaded rod from shifting when the blade holder moves downwards to a certain position via the threaded rod. Finally, the sliding rod facilitates rapid adjustment of the blade spacing to meet different creasing requirements.

[0004] However, existing creasing devices often have fixed blades during use, but the blades sometimes directly press and cut the packaging paper. Existing creasing devices cannot adjust the creasing depth of the packaging paper as needed.

[0005] Therefore, we need a roll-printed packaging paper creasing device to solve the creasing problem of existing packaging paper creasing devices, and also to achieve creasing depths for different packaging papers. Utility Model Content

[0006] The purpose of this utility model is to provide a roll printing packaging paper creasing device to solve the creasing problem of existing packaging paper creasing devices mentioned in the background art, and to achieve creasing depth for different packaging papers.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a roll printing packaging paper creasing device, including a workbench, the top surface of the workbench is fixedly connected to the bottom end of the side plate of a stabilizing frame, a hydraulic cylinder is fixedly connected to the inner top surface of the stabilizing frame, the end of the power output shaft of the hydraulic cylinder is fixedly connected to the top surface of a lifting frame, a rotating roller is rotatably connected between the two side plates of the lifting frame, and a compression plate is provided on the surface of the rotating roller.

[0008] Preferably, a drive motor is fixedly connected to the top surface of the lifting frame, a drive wheel is fixedly connected to the end of the power output shaft of the drive motor, the surface of the drive wheel is connected to the surface of the transmission wheel via a transmission belt, and the inner surface of the transmission wheel is fixedly connected to the end of the rotating shaft of the rotating roller.

[0009] Preferably, the side surface of the rotating roller is provided with a snap-fit ​​groove, the surface of the snap-fit ​​groove is inserted with a snap-fit ​​strip, the bottom surface of the snap-fit ​​strip is fixedly connected to the top surface of the compression plate, the surface of the rotating roller is provided with a through opening, the through opening and the snap-fit ​​groove are connected in communication, the surface of the through opening is fixedly connected to the end of the fixed rotating shaft, the surface of the fixed rotating shaft is rotatably connected to the inside of the limiting baffle, and the inner surface of the limiting baffle abuts against the surface of the snap-fit ​​strip.

[0010] Preferably, the side plate surface of the stabilizing frame has an opening that completely penetrates the side surface of the stabilizing frame.

[0011] Preferably, the snap-fit ​​groove is convex in shape, with its surface closely attached to the surface of the snap-fit ​​strip, and the snap-fit ​​groove does not completely penetrate the side surface of the rotating roller.

[0012] Preferably, the cross-section of the fixed rotating shaft is T-shaped, and the length of the fixed rotating shaft is equal to the depth of the opening.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: By rotatably connecting the end of the rotating roller to the two side plates of the lifting frame, and then setting a compression plate on the surface of the rotating roller, when the rotating roller rotates inside the lifting frame, the compression plate on its surface can indent the surface of the printed packaging paper on the top of the workbench. When the drive motor is started, the drive wheel rotates, and the transmission belt drives the drive wheel to automatically rotate the rotating roller inside the lifting frame. Therefore, the compression plate on the surface of the rotating roller can automatically indent the printed packaging paper on the top surface of the workbench. When it is necessary to press different depths of marks on the surface of the printed packaging paper, the compression plate can be removed from the surface of the rotating roller for replacement. This further solves the problem of indentation of packaging paper by existing packaging paper indentation devices, and can also achieve indentation depths for different packaging papers.

By rotatably connecting the rotating rod end of the rotating roller 6 between the two side plates of the lifting frame 5, and then providing the compression plate 7 on the surface of the rotating roller 6, when the rotating roller 6 rotates inside the lifting frame 5, the compression plate 7 on its surface can creasing the surface of the printed packaging paper on the top of the workbench 1. Example

[0021] See attached document Figures 1 to 4 Based on Embodiment 1, in order for the compression plate 7 to automatically crease the printed packaging paper on the top surface of the workbench 1, the top surface of the lifting frame 5 is fixedly connected to the drive motor 8, the end of the power output shaft of the drive motor 8 is fixedly connected to the drive wheel 9, the surface of the drive wheel 9 is connected to the surface of the drive wheel 11 through the transmission belt 10, and the inner surface of the drive wheel 11 is fixedly connected to the end of the rotating shaft of the rotating roller 6.

[0022] By fixing the inner surface of the drive wheel 9 to the end of the power output shaft of the drive motor 8, the drive wheel 9 rotates when the drive motor 8 is started. Therefore, the transmission belt 10 drives the transmission wheel 11 to drive the rotating roller 6 to rotate automatically inside the lifting frame 5. Thus, the surface compression plate 7 of the rotating roller 6 can automatically crease the top surface of the workbench 1 for printing packaging paper. Example

[0023] See attached document Figures 1 to 4 Based on Embodiment 2, in order to remove the compression plate 7 from the surface of the rotating roller 6 for replacement, a snap-fit ​​groove 15 is provided on the side surface of the rotating roller 6, and a snap-fit ​​strip 16 is inserted into the surface of the snap-fit ​​groove 15. The bottom surface of the snap-fit ​​strip 16 is fixedly connected to the top surface of the compression plate 7. A through-hole 12 is provided on the surface of the rotating roller 6, and the through-hole 12 and the snap-fit ​​groove 15 are connected. The end of the fixed rotating shaft 13 is fixedly connected to the surface of the fixed rotating shaft 13.
