The following embodiments are used to illustrate this utility model.

[0017] like Figures 1 to 4 As shown, a cardboard slotting cutter includes a frame 1.

[0018] A V-groove knife 6 is vertically inserted on the frame 1, a connecting post 7 is installed on the V-groove knife 6, and a locking rod 8 is rotatably installed on the connecting post 7; A positioning plate 10 is installed on the frame 1, and a through groove 11 is formed on the positioning plate 10. The through groove 11 is elliptical. Several pairs of locking components are installed on the frame 1, and the locking components include a pair of vertically arranged clamping plates 12. The shape of the clamping plates 12 is adapted to the shape of the through groove 11. A notch 17 is provided between the clamping plates 12. When the clamping plates 12 and the through groove 11 are staggered and aligned, the notch 17 is engaged in the through groove 11. The locking components are used to position the V-shaped groove cutter 6 extending out of the frame 1, thereby controlling the grooving depth. Through the cooperation of the above structure, not only can the position of the V-shaped groove cutter 6 be stably locked by the interaction of the locking components, the through groove 11, and the clamping rod 8, ensuring that the grooving depth is accurate and controllable, but also a convenient structural basis is provided for subsequent depth adjustment.

[0019] like Figures 1 to 4 As shown, in a specific embodiment, the frame 1 is U-shaped, and a connecting frame 2 is bolted to the top of the frame 1. A pair of bosses 3 are mounted on the connecting frame 2, and lifting rings 4 are mounted on the pair of bosses 3. The lifting rings 4 are used to connect with the output end of the grooving machine. The U-shaped frame 1 has a stable structure and can provide reliable support for each component. The connection with the grooving machine is achieved through the connecting frame 2, bosses 3, and lifting rings 4, which is convenient to install and has a firm connection, ensuring the stability of power transmission.

[0020] like Figures 1 to 4 As shown, a pressure plate 5 is further installed at the bottom of the frame 1. The connection between the pressure plate 5 and the frame 1 is straight, and the other end is curved to guide and press the paper. The curved end of the pressure plate 5 can effectively guide and stably press the paper, preventing the paper from shifting during slotting and ensuring the accuracy of the slotting position. The straight connection ensures the stability of the connection with the frame 1.

[0021] like Figures 1 to 4As shown, furthermore, a limiting plate 9 is installed on the top of the locking rod 8. The diameter of the limiting plate 9 is larger than the inner diameter of the through groove 11. The bottom of the locking rod 8 is rotatably installed in a groove opened on the surface of the connecting post 7. A coil spring 13 is provided inside the groove, with one end of the coil spring 13 connected to the connecting post 7 and the other end connected to the locking rod 8. The coil spring 13 is used to position the locking plate 12 in an interlocked position with the through groove 11 when no external force is applied. The limiting plate 9 can prevent the locking rod 8 from coming out of the through groove 11, ensuring structural integrity; the coil spring 13 can keep the locking plate 12 in an interlocked locked state with the through groove 11 when no external force is applied, ensuring the stability of the V-shaped groove knife 6 and improving the reliability of the structure.

[0022] like Figures 1 to 4 As shown, a sliding plate 14 is further installed on the side wall of the connecting column 7. A limit rod 15 is vertically slidably mounted on the sliding plate 14. The top of the limit rod 15 is installed on the bottom of the positioning plate 10, and the bottom of the limit rod 15 is installed on the frame 1. A return spring 16 is sleeved on the limit rod 15. One end of the return spring 16 is engaged with the sliding plate 14, and the other end of the return spring 16 is engaged with the bottom of the positioning plate 10. The cooperation between the sliding plate 14 and the limit rod 15 provides stable guidance for the up and down movement of the connecting column 7 and the V-groove cutter 6, preventing deviation. The return spring 16 can assist the components in resetting after adjustment, further improving the stability of the structure operation and the convenience of adjustment.

[0023] The implementation principle of a cardboard slotting cutter in this embodiment is as follows: When the cardboard slotting cutter is in use, it is first connected to the output end of the slotting machine through the lifting ring 4 on the top connecting frame 2 of the frame 1, so as to realize the power connection between the cutter and the slotting machine. The Z-shaped frame 1 provides a stable installation foundation for each component. In the initial state, under the action of the coil spring 13, the clamping plate 12 and the through groove 11 on the positioning plate 10 are in an interlocked position, and the notch 17 is engaged in the through groove 11, thereby firmly locking the position of the V-groove knife 6. At this time, the length of the V-groove knife 6 extending out of the frame 1 has been preset according to the required grooving depth and remains fixed during subsequent use. At the same time, the return spring 16 is in the natural state, and the slide plate 14 is in the initial position on the limit rod 15 corresponding to the position of the V-groove knife 6. When the slotting machine starts and the entire cutter moves downward, the pressure plate 5 at the bottom of the frame first contacts the cardboard. Its curved end acts as a guide, pressing the cardboard firmly and preventing it from shifting during the slotting process. As the cutter continues to move downward, the fixed-position V-shaped slotting knife 6 contacts the cardboard and begins slotting. Throughout this process, the V-shaped slotting knife 6 remains in a fixed position, and the slotting operation on the cardboard is achieved solely through the downward movement of the entire frame. After slotting is completed, the slotting machine moves the cutter upwards, and the pressure plate 5 moves upwards accordingly, releasing the pressure on the cardboard. The V-groove cutter 6 also moves upwards with the frame, detaching from the cardboard, completing one slotting cycle. During this process, the V-groove cutter 6 remains in its initial position and does not move up or down. If the grooving depth needs to be adjusted, it can be achieved by adjusting the locking assembly. Rotate the locking lever 8 to align the locking plate 12 with the through groove 11, releasing the lock on the V-groove cutter 6. At this time, the V-groove cutter 6 can be moved up and down to change its length extending out of the frame 1. After adjusting to the appropriate position, release the locking lever 8. Under the action of the coil spring 13, the locking plate 12 and the through groove 11 interlock again, and the notch 17 engages and fixes, and the V-groove cutter 6 is locked again to allow for a new grooving operation.
