[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Reference Figure 1-3 This utility model provides a creasing device for processing honeycomb cardboard, including a workbench 1. Cylinders 3 are fixedly installed on both sides of the middle part of the upper surface of the workbench 1. A support frame 301 is fixedly installed at the output end of the cylinders 3. A screw 308 is rotatably installed at one end of the support frame 301. A limit rod 309 is fixedly installed at the other end of the support frame 301. A guide plate 302 is provided between the screw 308 and the limit rod 309. One end of the guide plate 302 is threadedly connected to the screw 308, and the other end of the guide plate 302 is slidably connected to the limit rod 309. A servo motor 303 is fixedly installed on the top of the support frame 301. The output end of the servo motor 303 is fixedly connected to one end of the screw 308.

[0022] The support frame 301 is raised and lowered by the cylinder 3, thereby controlling the depth of the indentation. Under the control of the servo motor 303, the guide plate 302 is raised and lowered smoothly by the cooperation of the limit rod 309 and the screw 308. The support frame 301 is U-shaped and has a through slot in the middle, so it is not affected by the support frame 301 when the guide plate 302 is raised and lowered.

[0023] Two slide rails 304 are fixedly installed on the inner wall of the support frame 301. Symmetrical sliders 305 are slidably connected on the slide rails 304. A connecting plate 306 is fixedly connected to the outer side of each set of symmetrical sliders 305. A rotating shaft 307 is fixedly installed in the middle of the connecting plate 306. Multiple sets of symmetrical guide grooves are opened through the surface of the guide plate 302. The rotating shaft 307 is slidably connected to the corresponding guide groove.

[0024] The up-and-down movement of the guide plate 302 causes the rotating shaft 307 to move within the guide groove opened in the guide plate 302. The guide grooves have different lengths but the same longitudinal height. The closer the guide groove is to the center of the guide plate 302, the smaller the inclination angle. This allows the rotating shaft 307 to move within the guide groove, thereby controlling the distance between the connecting plate 306 when it is in contact with the slider 305 and the slide rail 304.

[0025] The workbench 1 has a through slot running from front to back. Drive shafts 202 are rotatably mounted at both ends inside the workbench 1. A conveyor belt 2 is driven between the outer sides of the two drive shafts 202. A drive motor 201 is fixedly mounted on the outer side of the workbench 1, and the output end of the drive motor 201 is fixedly connected to one end of the drive shafts 202. The upper surface of the workbench 1 is flush with the through slot. The width of the conveyor belt 2 is the same as the opening on the upper surface of the workbench 1, allowing the conveyor belt 2 to transport honeycomb cardboard to the maximum extent. Through the design of the workbench 1 running from front to back and through the through slot on its upper surface, the conveyor belt 2 and drive shafts 202 can be installed inside the workbench 1, working in conjunction with the drive motor 201 to transport the honeycomb cardboard.

[0026] Mounting seats 101 are fixedly installed on both sides of the workbench 1. A bidirectional screw 103 is rotatably mounted between the mounting seats 101 at one end. A servo motor 105 is fixedly mounted on the outside of the mounting seat 101, and the output end of the servo motor 105 is fixedly connected to one end of the bidirectional screw 103. A slide rod 104 is fixedly installed between the mounting seats 101 at the other end. Limiting plates 102 are symmetrically arranged on both sides of the workbench 1. Protrusions are fixedly connected to both ends of the limiting plates 102. One end of the two limiting plates 102 is threadedly connected to the bidirectional screw 103 through the protrusions, and the other end of the two limiting plates 102 is slidably connected to the slide rod 104 through the protrusions. The distance between the limiting plates 102 can be adjusted by controlling the servo motor 105, which helps to limit and fix honeycomb cardboard of different sizes, preventing displacement and uneven indentation. The bidirectional screw 103 and the slide rod 104 are far from the conveyor belt 2, so they do not affect the transportation of the honeycomb cardboard.

[0027] The limiting plate 102 is close to the upper surface of the conveyor belt 2, and the limiting plate 102 does not contact the conveyor belt 2, so as to better limit the conveyed honeycomb cardboard.

[0028] A creasing mechanism is fixedly installed at the lower end of the connecting plate 306. The creasing mechanism includes a mounting frame 4, a pressure roller 401, and a locking bolt 402. The connecting plate 306 is L-shaped, and the mounting frame 4 is provided on the lower surface of the connecting plate 306. The connecting plate 306 is fixedly connected to the mounting frame 4 by the locking bolt 402. The pressure roller 401 is fixedly installed in the mounting frame 4. The installation of the mounting frame 4 and the pressure roller 401 with the connecting plate 306 is controlled by the locking bolt 402, thereby further meeting the creasing requirements of the honeycomb paperboard.

[0029] When the guide plate 302 moves to its lowest position, its bottom surface does not contact the protruding part at the lower end of the connecting plate 306. This prevents the guide plate 302 from affecting the control spacing between the pressure rollers.

[0030] The working principle of this utility model is as follows: First, according to the creasing requirements, the installation of the pressure roller 401 is controlled by the locking bolt 402. Then, in accordance with the size of the honeycomb paperboard, a servo motor 105 is set up to control the limiting plate to limit the honeycomb paperboard and prevent deviation. Next, a servo motor 303 is set up to control the guide plate 302 to rise and fall, so that the rotating shaft 307 moves along the guide groove. With the cooperation of the slider 305 and the slide rail 304, the connecting plate 306 is moved synchronously, thereby adjusting the spacing of the pressure rollers 401 fixedly connected below the connecting plate 306 to match the honeycomb paperboard. Finally, the drive motor 201 is turned on to transport and creasing the honeycomb paperboard.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. This utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
