Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of carton production equipment, in particular to a carton creasing device for carton production. Background Art
[0002] The carton creasing devices widely used in the current carton production industry play an important role in improving production efficiency and ensuring the basic forming quality of cartons. However, the existing carton creasing devices generally lack a flexible and effective creasing depth adjustment structure. This defect directly leads to the difficulty in accurately controlling the creasing depth when facing carton boards of different thicknesses and materials in practical applications, thus making it difficult to meet diverse production needs. Specifically, carton products from different customers or different batches of the same customer often have different requirements on the compressive strength, foldability and other properties of the carton due to differences in design specifications, load-bearing requirements or packaging contents. The indentation is too shallow, which may cause the carton to deform or break during folding or stacking, affecting the packaging effect and product protection; while the indentation is too deep, which may weaken the overall strength of the carton, and even damage the internal structure of the carton in some cases, reducing its performance. Most of the existing carton indentation devices adopt a fixed indentation mold design, which cannot accurately adjust the depth according to the actual thickness and material characteristics of the carton. This "one-size-fits-all" production method not only limits the flexibility and adaptability of the production line, but also increases the defective rate and production costs. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. The following is an explanation of the embodiments of the present utility model based on the overall structure of the present utility model.
[0020] Reference Figures 1 to 4In the embodiment of the utility model, a carton creasing device for carton production includes: a workbench 1, a side plate 2 is fixedly connected to the top of the workbench 1, a screw rod 3 is arranged inside the side plate 2, an operating handle 4 is arranged above the side plate 2, a lifting plate 5 is screwed to one end of the screw rod 3, a receiving plate 6 is fixedly connected to the side of the lifting plate 5, a top plate 7 is fixedly connected to the side of the side plate 2, a damping rod 8 is arranged below the top plate 7, a spring 9 is sleeved on the outer side of the damping rod 8, a movable plate 10 is fixedly connected to the lower side of the damping rod 8, a connecting plate 11 is fixedly connected to the side of the movable plate 10, a servo motor 12 is installed on the side of the connecting plate 11, a rotating rod 13 is arranged on the other side of the connecting plate 11, a pressing wheel 14 is fixedly connected to the outer side of the rotating rod 13, and the side plate 2. There are two groups of screw rod 3, operating handle 4, lifting plate 5, receiving plate 6, top plate 7, movable plate 10 and connecting plate 11, and the rotating rod 13 is arranged between the two groups of connecting plates 11 and connected to the servo motor 12. The screw rod 3 is connected to the operating handle 4. A threaded hole matching the external thread of the screw rod 3 is opened on the top of the lifting plate 5. There are four groups of damping rods 8 and springs 9, and the movable plate 10 is placed on the receiving plate 6. The operator rotates the screw rod 3 by operating the handle 4, and the screw rod 3 cooperates with the threaded hole on the lifting plate 5 to realize the up and down movement of the lifting plate 5. This step is used to adjust the height of the indentation device to adapt to different thicknesses. At the same time, the combination of the damping rod 8 and the spring 9 provides a buffer and stabilizing effect for the movable plate 10, ensuring that the movable plate 10 can smoothly descend and apply uniform pressure during the creasing process. When the lifting plate 5 is adjusted to an appropriate position, the servo motor 12 is started, and the servo motor 12 drives the rotating rod 13 to rotate through the connecting plate 11, thereby driving the pressing wheel 14 to perform a circular motion. The pressing wheel 14 is the core component of the creasing device. Its material and shape are carefully designed to ensure that clear folds can be formed during the creasing process without causing excessive damage to the cardboard. The control of the creasing depth is achieved through the precise control of the servo motor and the fine adjustment of the lifting plate 5. The servo motor can adjust the rotation speed and downward pressure of the pressing wheel 14 according to the preset program or the operator's instructions, so as to achieve precise control of the indentation depth. At the same time, the fine-tuning function of the lifting plate 5 allows the operator to make fine adjustments according to actual conditions during the indentation process to ensure the uniformity and consistency of the indentation depth. During the indentation process, the combination of the damping rod 8 and the spring 9 plays an important buffering role. They can absorb the impact force generated when the pressing wheel 14 is pressed down, reduce vibration and noise, and protect the equipment from damage. At the same time, after the indentation is completed, the elastic force of the spring 9 helps the movable plate 10 to quickly reset and prepare for the next indentation operation.
[0021] Reference Figure 1 to Figure 2A rotating plate 15 is rotatably connected above the workbench 1, and a cardboard limiting plate 16 is hinged at one end of the rotating plate 15. There are two groups of rotating plates 15 and cardboard limiting plates 16, and locking bolts are provided at the rotating positions of the rotating plates 15 and cardboard limiting plates 16, and the tightness can be controlled by the locking bolts. First, the carton cardboard to be indented is placed on the workbench 1, and the precise positioning of the cardboard is achieved through the combination of the rotating plate 15 and the cardboard limiting plate 16. The rotating plate 15 can be adjusted according to the width of the cardboard and fixed in position by the locking bolts to ensure that the cardboard remains stable and does not move during the indentation process. The cardboard limiting plate 16 further limits the lateral movement of the cardboard to improve the accuracy of indentation.
[0022] Reference Figure 1 to Figure 2 A supporting leg 17 is fixedly connected to the bottom of the workbench 1, a reinforcing rod 18 is fixedly connected to the side of the supporting leg 17, a material unloading chute 19 is opened on one side of the workbench 1, and four groups of supporting legs 17 and reinforcing rods 18 are provided, which are symmetrically arranged at the four ends below the workbench 1, and the reinforcing rod 18 is fixedly connected between the workbench 1 and the supporting legs 17. The carton paperboard that has completed the indentation can automatically slide to the collection area through the unloading chute 19 on one side of the workbench 1, so as to realize fast unloading and continuous production. The design of the unloading chute 19 takes into account the size and weight of the paperboard to ensure that the paperboard can slide smoothly without getting stuck.
[0023] The working principle of the utility model is as follows: first, the carton paperboard to be indented is placed on the workbench 1, and the precise positioning of the paperboard is achieved through the combination of the rotating plate 15 and the paperboard limiting plate 16. The rotating plate 15 can be adjusted according to the width of the paperboard, and the position is fixed by the locking bolt to ensure that the paperboard remains stable and does not move during the indentation process. The paperboard limiting plate 16 further limits the lateral movement of the paperboard to improve the accuracy of the indentation. The operator rotates the screw rod 3 by operating the handle 4, and the lifting plate 5 is moved up and down by the cooperation between the screw rod 3 and the threaded hole above the lifting plate 5. This step is used to adjust the height of the indentation device to adapt to carton paperboards of different thicknesses. At the same time, the combination of the damping rod 8 and the spring 9 provides a buffer and a stabilizing effect for the movable plate 10, ensuring that the movable plate 10 can smoothly descend and apply uniform pressure during the indentation process. When the lifting plate 5 is adjusted to the appropriate position, the servo motor 12 is started, and the servo motor 12 drives the rotating rod 13 to rotate through the connecting plate 11, thereby driving the pressing wheel 14 to perform a circular motion. The pressing wheel 14 is the core component of the indentation device, and its material and shape are carefully designed. The design is to ensure that clear creases can be formed during the creasing process without causing excessive damage to the cardboard. The control of the creasing depth can be achieved through the precise control of the servo motor and the fine adjustment of the lifting plate 5. The servo motor can adjust the rotation speed and downward pressure of the pressing wheel 14 according to the preset program or the operator's instruction, so as to achieve precise control of the creasing depth. At the same time, the fine adjustment function of the lifting plate 5 allows the operator to make fine adjustments according to the actual situation during the creasing process to ensure the uniformity and consistency of the creasing depth. During the creasing process, the combination of the damping rod 8 and the spring 9 plays an important buffering role. They can absorb the impact force generated when the pressing wheel 14 is pressed down, reduce vibration and noise, and protect the equipment from damage. At the same time, after the creasing is completed, the elastic force of the spring 9 helps the movable plate 10 to quickly reset and prepare for the next creasing operation. The carton cardboard that has completed the creasing can automatically slide to the collection area through the unloading chute 19 on one side of the workbench 1, so as to achieve fast unloading and continuous production. The design of the unloading chute 19 takes into account the size and weight of the cardboard to ensure that the cardboard can slide smoothly without blocking.
