[0002] In the corrugated cardboard manufacturing process, slotting is one of the key steps determining the quality of the formed cardboard and its subsequent performance. This step requires precisely cutting slots into the corrugated cardboard to facilitate folding, allowing the cardboard to be folded into the box body, lid, and other structures according to preset dimensions. Simultaneously, it ensures that the slot edges are smooth, preventing problems such as cardboard breakage and misalignment during folding. With the rapid development of industries such as logistics and e-commerce, the market demand for cardboard boxes continues to rise, placing higher demands on the diversity of cardboard box specifications, dimensional accuracy, and production efficiency. As the equipment that completes this core process, the performance of the slotting machine directly affects the production capacity and product competitiveness of cardboard box manufacturers.

[0003] In the existing technology, during the slotting process of carton production, the cardboard is usually transferred manually to the slotting machine for automatic slotting. After slotting, the cardboard can be replaced. However, the existing equipment can generally only slot the cardboard of one type of carton. When it is necessary to change to a different cardboard, professional mechanics are required to adjust the position of the cutter, which greatly increases the workload and reduces production efficiency. Therefore, a slotting machine for carton production and processing was designed. Utility Model Content

The cutting mechanism 3 away from the L-shaped positioning plate 5 can be operated as needed. When not in use, it can be moved to the far side, and the lever 311 is pulled to compress the spring 309 of the pressure plate 310, which will separate the locking block 312 from the locking slot 103, thus realizing the movement of the strip block 301. After moving to the desired position, the lever 311 is released to fix the cutting mechanism 3. The reduction motor 201 is connected to the mains power through the controller. In use, the reduction motor 201 drives the rotating rod 203 to rotate through the L-shaped rod 202. Due to the setting of the L-shaped rod 202, the rotating rod 203 makes a circular motion at the top. Through the sliding sleeve 306 and the connecting rod 305, the rotating plate 303 carries the U-shaped cutter 304 and moves cyclically during the rising and falling process. Figure 2 In the upward position, the user picks up the cardboard for producing cartons, so that one end abuts against the L-shaped positioning plate 5 and the other side abuts against multiple positioning blocks 404, thus positioning the cardboard. When the rotating plate 303 descends with the U-shaped cutter 304, one side of the cardboard can be slotted. When it is necessary to slot different types of cardboard, by pulling the lever 311, the locking block 312 can be separated from the locking slot 103, realizing the rapid movement of the strip block 301. This facilitates slotting different types of cartons. If professional staff need to make complicated adjustments, they can make adjustments.
