DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The following will further describe the specific embodiments of the present utility model in conjunction with the drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solutions of the present utility model and cannot be used to limit the protection scope of the present utility model.

[0018] As Figures 1-3As shown in the figure, the utility model is a creasing device for carton processing, including a workbench 1. A motor 2 is fixedly arranged at the side end of the workbench 1. A lead screw 21 is arranged at the output end of the motor 2. A slider 22 is threadedly connected to the lead screw 21. By turning on the switch of the motor 2, the output end of the motor 2 drives the lead screw 21 to rotate. When the lead screw 21 on one side of the workbench 1 starts to rotate, the slider 22 threadedly connected to the lead screw 21 starts to move back and forth on the workbench 1, and then can drive the creasing knife 32 to move back and forth on the workbench 1. Place the carton to be creased on the workbench 1. The position of the required crease can be adjusted by adjusting the front and back position of the workbench 1. When it is necessary to perform creasing work on another position of the carton after a crease is completed at one place of the carton, it is not necessary to fix the carton again. The front and back position of the creasing knife 32 can be adjusted, and then the creasing work can be performed on the remaining position of the carton again, which is convenient for workers to operate.

[0019] A hydraulic cylinder 24 is fixedly arranged at the top of the slider 22. A support plate 25 is fixedly arranged at the output end of the hydraulic cylinder 24. A connecting rod 26 is fixedly arranged at the lower end of the support plate 25. The bottom end of the connecting rod 26 is connected to a fixed block 3. When starting the creasing work, by turning on the external power supply switch of the hydraulic cylinder 24, the hydraulic cylinder 24 drives the support plate 25 to start moving downward, driving the creasing knife 32 to start moving downward to perform creasing work on the surface of the carton.

[0020] A positioning groove 31 is arranged in the fixed block 3. A creasing knife 32 is installed in the positioning groove 31. A second screw 34 is threadedly connected in the fixed block 3. When it is necessary to replace and repair the creasing knife 32, by turning the handle outside the second screw 34, because the second screw 34 is threadedly connected to the thread groove in the fixed block 3, when the second screw 34 starts to rotate, the second screw 34 can move outwards from the fixed block 3. An insertion port 33 is arranged on one side of the creasing knife 32. The second screw 34 is slidably connected to the insertion port 33. During the process of the second screw 34 starting to move outwards, the second screw 34 can slide outwards from the insertion port 33 on the side of the creasing knife 32, releasing the restrictive effect on the creasing knife 32, and sliding the creasing knife 32 outwards from the positioning groove 31, then the creasing knife 32 can be taken out, which is convenient for replacing and repairing the creasing knife 32.

[0021] A sleeve 4 is provided at the lower end of the fixed block 3. A slide plate 41 is slidably connected inside the sleeve 4. A spring 43 is provided on one side of the slide plate 41, and a positioning plate 42 is provided on the other side. When the support plate 25 drives the creasing knife 32 to start moving downward, before the creasing knife 32 touches the surface of the cardboard box, the positioning plate 42 first contacts the surface of the cardboard box. One end of the spring 43 is connected to the inner wall of the sleeve 4, and the other end is connected to the upper end of the slide plate 41. After the positioning plate 42 contacts the surface of the cardboard box, the support plate 25 continues to move downward. The positioning plate 42 drives the slide plate 41 to slide, and the slide plate 41 squeezes the spring 43. On the one hand, it can stabilize the cardboard box during the creasing operation of the cardboard box, avoid fluctuations in the creasing position of the cardboard box during the creasing process, and affect the creasing effect. On the other hand, it can avoid excessive instantaneous impact force when the positioning plate 42 moves downward, causing damage to the cardboard box.

[0022] In the above solution, legs 11 are provided at the lower end of the workbench 1.

[0023] In the above solution, a fixed frame 12 is provided on the workbench 1. A first screw rod 13 is threadedly connected to the fixed frame 12. A limiting plate 14 is provided at the bottom of the first screw rod 13. Place the cardboard box to be creased on the workbench. By rotating the first screw rod 13, the rotation of the first screw rod 13 can drive the limiting plate 14 to move downward to fix the cardboard box to be creased, which can initially fix the cardboard box and further ensure the stability during the creasing process of the cardboard box.

[0024] In the above solution, two second screw rods 34 and sleeves 4 are provided on the side of the fixed block 3. The two second screw rods 34 can ensure the stability of the creasing knife 32 fixed in the fixed block 3. Through the two sleeves 4 provided, the cardboard box to be creased can be pressed and stabilized.

[0025] In the above solution, a slide rod 23 is provided on the other side of the workbench 1. Another slider 22 slides on the slide rod 23. The tops of the two sliders 22 are both connected to hydraulic cylinders 24. Through the slide rod 23 provided, it can play a role in limiting and guiding the sliding of the slider 22, ensuring that the two sliders 22 stably drive the two hydraulic cylinders 24 to move back and forth.

[0026] Working principle:

[0027] For the indentation device used in carton processing, during specific operation, place the carton that requires creasing on the workbench. By rotating the first screw rod 13, the rotation of the first screw rod 13 can drive the limiting plate 14 to move downward to fix the carton that requires creasing. By turning on the external power switch of the hydraulic cylinder 24, the hydraulic cylinder 24 drives the support plate 25 to start moving downward, driving the creasing knife 32 to start moving downward to perform the creasing work on the surface of the carton. Before the creasing knife 32 touches the surface of the carton, the positioning plate 42 first contacts the surface of the carton. The positioning plate 42 drives the sliding plate 41 to slide, and the sliding plate 41 squeezes the spring 43. On the one hand, it can stabilize the carton during the creasing work of the carton, avoiding fluctuations in the creasing position of the carton during the creasing process and affecting the creasing effect. On the other hand, it can avoid excessive instantaneous impact force when the positioning plate 42 moves downward and cause damage to the carton. When creasing work needs to be performed on another position of the carton, by turning on the switch of the motor 2, the slider 22 threadedly connected to the lead screw 21 starts to move back and forth on the workbench 1, and then can drive the creasing knife 32 to move back and forth on the workbench 1, so as to perform the creasing work on the remaining positions of the carton again, which is convenient for workers to operate.

[0028] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
