[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0025] Example 1:

[0026] Please see Figures 1-5 A slotting device for bending a cardboard box includes an operating table 1. A pusher 2 is provided at one end of the top of the operating table 1. Fixed plates 3 are provided on both sides of the operating table 1. A lifting frame 4 is fixedly installed on the top of the fixed plate 3. A lifting rod 41 is fixedly installed inside the lifting frame 4. The lifting rod 41 is slidably connected to the connecting blocks 71 fixed at both ends of the adjusting frame 7. Multiple connecting holes 72 are provided on both sides of the adjusting frame 7. An adjusting groove 73 is provided inside the adjusting frame 7. An installation frame 8 is slidably installed in the adjusting groove 73. The bottom of the installation frame 8 is connected to the slotting component 9 by connecting bolts 83.

[0027] The mounting bracket 8 has a movable groove 85 inside, and a connecting plate 87 is fixedly installed in the movable groove 85. Springs 86 are connected to both sides of the connecting plate 87. The connecting plate 87 is connected to the movable block 84 through the springs 86. A connecting rod 82 is provided on the side of the movable block 84 away from the springs 86. The connecting rod 82 is adapted to the connecting hole 72.

[0028] Specifically, the cardboard box is slotted using the slotting component 9, which includes a motor and a slotting blade. During slotting, the motor controls the rotation of the slotting blade to achieve the desired slotting. When different slotting sizes are required, the moving block 84 moves along the moving groove 85, causing the connecting rod 82 to move out of the connecting hole 72 and compressing the spring 86, retracting the connecting rod 82 into the moving groove 85. This allows the mounting frame 8 to move along the adjusting groove 73. When the mounting frame 8 reaches the appropriate position, the spring 86... 6. Restore the original state, causing the connecting rod 82 to enter the moved connecting hole 72, thereby completing the fixation of the mounting bracket 8 and adjusting the spacing between the slotted parts 9. Use the connecting bolt 83 to connect the mounting bracket 8 and the slotted parts 9 to achieve a detachable connection between the mounting bracket 8 and the slotted parts 9. When it is necessary to replace the slotted parts 9 of different specifications to adapt to different sizes of cartons, the original slotted parts 9 can be quickly removed and the new slotted parts 9 can be installed, which can improve production efficiency. When fewer slots are needed, the required slotted parts 9 can be removed to avoid affecting the slotting of the cartons.

[0029] Example 2:

[0030] To facilitate the movement of moving block 84, please refer to [link / reference]. Figures 1-5 Based on embodiment 1, a movable frame 81 is provided on the top of the mounting frame 8, and a second spring 813 is fixedly provided inside the movable frame 81. The top of the second spring 813 is connected to the movable plate 815, and the movable plate 815 is slidably disposed in the movable frame 81.

[0031] A button 812 is fixedly connected to the top center of the movable plate 815. One end of the button 812 passes through the top of the movable frame 81. Slide rods 814 are fixedly connected to both sides of the bottom of the movable plate 815.

[0032] The movable block 84 has slots 841 on both sides, and the slots 841 are inclined. The slots 841 at both ends of the movable groove 85 are symmetrically arranged. The bottom ends of the slide rod 814 are provided with protrusions, and the protrusions at both ends of the bottom of the slide rod 814 are slidably arranged in the slots 841.

[0033] Handles 811 are fixedly connected to both sides of the movable frame 81.

[0034] Specifically, the protrusions at both ends of the bottom of the slide rod 814 are slidably disposed in the groove 841, so that when the slide rod 814 moves downward, the protrusions move along the groove 841. The groove 841 is inclined, so that when the protrusions move, they squeeze the groove 841, causing the moving block 84 to move inward along the moving groove 85, thereby controlling the connecting rod 82 to enter the moving groove 85. By pressing the button 812, the moving plate 815 is controlled to press down on the slide rod 814. During this process, spring 813 is compressed and undergoes elastic deformation. When the mounting bracket 8 moves to the appropriate position, the operator releases the pressure on button 812, causing spring 813 to lose its external force restriction and return to its original state. This pushes button 812 and moving plate 815 upward, thereby driving slide rod 814 to control protrusion to move upward. This, in turn, causes moving block 84 to be pushed by spring 86 and protrusion, controlling connecting rod 82 to enter connecting hole 72, thus completing convenient control of moving block 84.

[0035] When pressing button 812, the operator can press the button 812 with their thumb and place the other fingers under the grip plate 811. This operation method conforms to the ergonomic principle and is a natural and comfortable hand action. It can reduce the operator's hand fatigue, enable convenient control of the mounting bracket 8 to move, and improve work efficiency.

[0036] Example 3:

[0037] To perform slotting on the cardboard box, please refer to [link / reference]. Figures 1-5 Based on Embodiment 1 and Embodiment 2, a frame 6 is fixedly installed on the top of the adjusting frame 7, and an electric telescopic rod 5 is installed in the middle of the top of the frame 6. The electric telescopic rod 5 is fixed on the lifting frame 4.

[0038] Multiple springs 31 are connected to the inner side of the fixed plate 3. The fixed plate 3 is connected to the clamping plate 32 through the springs 31. The clamping plate 32 is slidably set on the top of the operating table 1.

[0039] Specifically, after the spacing between the slotted parts 9 is adjusted, the operator places the carton in the middle of the clamping plate 32. The carton will first contact the clamping plate 32. Since the clamping plate 32 and the fixing plate 3 are connected by spring 31, the presence of the carton will exert a squeezing force on the clamping plate 32, causing the spring 31 to be compressed. When the carton is completely placed in the middle of the clamping plate 32, the restoring force of the spring 31 will continue to act on the clamping plate 32, so that the clamping plate 32 tightly clamps the carton.

[0040] During slotting, the electric telescopic rod 5 extends to control the frame 6 and pushes the adjusting frame 7 to move along the lifting rod 41. The lifting rod 41 is used to guide the lifting of the adjusting frame 7, making the lifting of the adjusting frame 7 more stable. By extending the electric telescopic rod 5 to different lengths, the slotting part 9 makes different slotting depths on the carton. The pushing part 2 pushes the carton to move, so that the slotting part 9 can open long strip bending grooves on the carton.

[0041] Working principle: When the equipment is in use, in order to meet the slotting requirements of different sized cartons, the connecting rod 82 is first moved into the moving groove 85 by pressing the button 812, so that it can be disengaged from the original connecting hole 72. This makes it easy for the operator to move the slotting part 9 along the adjusting groove 73 by using the mounting frame 8, thereby adjusting the spacing between different slotting parts 9 to suit the slotting of cartons of special sizes. When slotting, the carton is first placed in the middle of the clamping plate 32. The clamping plate 32 stably clamps the carton by using the spring 31. At the same time, the electric telescopic rod 5 in the equipment drives the adjusting frame 7 to descend along the lifting rod 41 through the extension control frame 6, so that the slotting part 9 can contact the carton. The pushing part 2 pushes the carton to move, so that the slotting part 9 can slot along the bend.
