Description

Technical Field

[0001] This utility model relates to the field of cardboard box processing technology, specifically to a creasing device for producing folding cardboard boxes. Background Technology

[0002] Folding cartons refer to products packaged in paper boxes during the distribution process to protect the product, facilitate storage and transportation, and promote sales. A common flat layout of folding cartons shows four vertical crease lines and two horizontal crease lines. These crease lines need to be created by crease equipment during production. Some existing crease machines require a second vertical crease operation when performing horizontal creases on the cartons.

[0003] Chinese patent CN217258717U discloses a carton creasing device, including an operating table. A housing is fixedly connected to the top of the operating table, and a working chamber is formed inside the housing. A drive mechanism is arranged inside the working chamber, and a pre-pressure buffer mechanism is arranged on the bottom left side of the drive mechanism. The drive mechanism includes a bidirectional hydraulic cylinder, a piston rod, a gear, a rotating shaft, a threaded rod, a lifting column, a knife holder, and a pressure knife. The bottom of the bidirectional hydraulic cylinder is fixedly connected to the middle of the bottom of the working chamber, and the right end of the piston rod is telescopically connected to the left end of the bidirectional hydraulic cylinder. When this carton creasing device is used, the cardboard is placed in the middle of the top of the operating table, and then the knife holder is raised and lowered by the drive mechanism, thereby pressing down the pressure knife. Before the pressure knife contacts the cardboard, the pre-pressure buffer mechanisms on both sides press against the cardboard in advance, keeping the cardboard stable and ensuring the accuracy of the creasing.

[0004] However, in actual use, the pressure knife of this device can only perform vertical creases. When the folded carton needs to be creased horizontally, the device can only manually remove the folded carton, put it back in place, and then crease it again, which increases the workload.

[0018] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0019] Please see Figures 1-4 This utility model provides a technical solution: a creasing device for producing folded cartons, including a folded carton 3 placed on the upper end of a workbench 2. The creasing device includes a fixed frame 1 and a connecting plate 7. The fixed frame 1 can support the entire device. The workbench 2 can hold materials such as the folded carton 3. The inner wall of the fixed frame 1 is slidably connected to both ends of a transmission plate 5, thereby limiting the transmission plate 5 to prevent it from shaking. A cylinder 4 is fixedly connected to the upper end of the fixed frame 1, and the output end of the cylinder 4 is fixedly connected to the transmission plate 5. The cylinder 4 is an integral power unit. The cylinder (4) drives the transmission plate 5 to move up and down. The two ends of the transmission plate 5 are fixedly connected to the transmission rods 6. The two ends of the connecting plate 7 are respectively sleeved on the surfaces of the two transmission rods 6. At this time, the connecting plate 7 can slide on the surface of the transmission rods 6. The connecting piece 19 is fixedly connected at the midpoint of the connecting plate 7. The lower end of the connecting piece 19 is fixedly connected to the pressure knife 9. The pressure knife 9 moves with the connecting plate 7. Several ear seats 10 are fixedly connected to the side of the pressure knife 9. The ear seats 10 can make the two sides balanced.

[0020] After placing the folded cardboard box 3 on the workbench, the cylinder 4 will be activated. At this time, the transmission plate 5 will move vertically, so that the transmission rod 6 will also move synchronously.

[0021] The surfaces at both ends of the connecting plate 7 are slidably connected to the pressure knife 8. Fixed posts 16 penetrate both ends of the connecting plate 7, and the fixed posts 16 can guide the connecting plate 7. The fixed posts 16 are sleeved in the connecting plate 7. The upper end of the fixed post 16 is fixedly connected to the limit plate 18, which can prevent the fixed post 16 from coming off the connecting plate 7. The lower end of the fixed post 16 is fixedly connected to the fixed plate 17, which is fixedly connected to the lower end of the transmission rod 6. When the transmission rod 6 starts to move, the fixed post 16 can be driven to move synchronously through the fixed plate 17. The upper end of the fixed plate 17 is fixedly connected to the spring 12, and the other end of the spring 12 is fixedly connected to the connecting plate 7. The spring 12 can prevent the connecting plate 7 from sliding downward too early. The fixed post 16 is located at the midpoint of the spring 12, thereby improving the stability of the spring 12.

[0022] When the transmission rod 6 moves downward, the limiting plate 18 gradually contacts the connecting plate 7. Subsequently, the limiting plate 18 drives the connecting plate 7 to move downward, thereby causing the pressure knife 9 to move downward and contact the folded carton 3.

[0023] The two ends of the pressure knife 18 are threadedly connected to the threaded cylinder 15. The inner wall of the threaded cylinder 15 contacts the lower end of the fixed plate 17. When the threaded cylinder 15 is installed, the pressure knife 18 and the threaded cylinder 15 can be regarded as a closed whole on the lower side. Several lugs 10 are fixedly connected to both sides of the pressure knife 18. The pressure knife 18 and the pressure knife 2 9 are perpendicular to each other, so as to facilitate the simultaneous horizontal and vertical creasing operations. Several lugs 10 are slidably connected to guide posts 11. The lower end of the guide post 11 is fixedly connected to the pad 14. The pad 14 can be used to fix the folded carton 3 before the creasing operation. The upper end of the pad 14 is fixedly connected to the spring 2 13. The other end of the spring 2 13 is fixedly connected to the lug 10. The guide post 11 passes through the center of the spring 2 13. The spring 2 13 can enhance the pressure of the pad 14 and facilitate its reset.

[0024] When the threaded cylinder 15 is installed at both ends of the pressure knife 9, the transmission rod 6 moves down and contacts the inner wall of the threaded cylinder 15. The threaded cylinder 15 allows the pressure knife 8 to crease the folded carton 3. When the threaded cylinder 15 is removed, the pressure knife 8 will be supported by the connecting plate 7 during the downward movement of the transmission rod 6. When the pressure knife 8 contacts the folded carton 3, the next transmission rod 6 continues. At this time, the connecting plate 7 will drive the pressure knife 9 to approach the folded carton 3. When the two contact, the transmission rod 6 applies pressure to the connecting plate 7 through the spring 12, causing the connecting plate 7 to drive the pressure knife 8 and the pressure knife 9 to start the crease operation.

[0025] In actual use, after verifying that the device is correct, place the folded carton 3 on the upper end of the workbench 2. When unidirectional creasing is required, start the cylinder 4 to drive the pressure knife 8 through the threaded cylinder 15 to perform the creasing operation. When bidirectional creasing is required, remove the threaded cylinder 15. At this time, when the pressure knife 8 and the pressure knife 9 come into contact with the folded carton 3, the transmission rod 6 will apply pressure to the pressure knife 8 and the pressure knife 9 simultaneously through the connecting plate 7, thereby completing the bidirectional creasing operation.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
