[0002] Paper cups, as common food packaging containers, are typically produced by cutting rolls or sheets of raw paper into specific fan-shaped sheets for subsequent forming into cup bodies. In this production process, cutting precision, efficiency, and operational safety are crucial. Currently, common cutting methods include stamping using fixed molds or continuous or step-by-step cutting with rotary cutting tools. Rotary cutting, due to its higher efficiency, is widely used in mass production. These devices typically include a worktable, drive mechanism, cutting blades, and components for positioning the raw materials to achieve precise segmentation.

[0003] However, existing rotary cutting devices for paper cup raw materials still have some problems that urgently need to be solved in practical applications. First, the high-speed rotating cutting blades are directly exposed, posing a significant safety hazard to operators, and the flying debris generated during cutting can easily contaminate the working environment or affect equipment operation. Second, when cutting raw materials of different specifications or thicknesses, how to quickly and stably adjust the cutting position (height and horizontal feed) and ensure the smoothness of the cutting process, while also considering ease of operation, is key to improving the adaptability and efficiency of the equipment. Furthermore, effective positioning and clamping of the raw material during the cutting process is crucial to ensuring the neatness of the cut edges; some existing positioning and clamping structures may be cumbersome to operate or lack adaptability. In addition, the ease of equipment maintenance, especially the observation and cleaning of key cutting components, is also an important factor affecting the continuous and stable operation of the equipment. These problems, to some extent, restrict further improvements in production efficiency and operational safety. Utility Model Content

A lead screw 4 rotatably mounted between the bearing seats 3 rotates under the action of a drive motor 19, driving a threaded nut seat 5 to move horizontally along a fixed slide rod 18, achieving precise lateral feed positioning of the cutting wheel 9. An electric push rod 6 installed in front of the nut seat 5 can independently drive the mounting plate 7 and the right-angle mounting seat 8 to rise and fall, enabling the cutting wheel 9 to quickly adapt to the cutting depth requirements of materials of different thicknesses. The cutting wheel 9 is rotatably mounted on the outside of the right-angle mounting seat 8 and driven by its own motor for efficient operation. Rotary cutting; a transparent protective cover 10 covers the area of ​​the cutting wheel 9, and its top is fixed to the nut seat 5 by a connecting piece 11 and bolts, forming a closed space to block flying debris and prevent operation contact, while facilitating observation of the internal operation; the front and rear positioning plates 12 fixed on the worktable 1 form a cutting groove 13 to accommodate the downward movement of the cutting wheel 9, and the guide rod 14 on the positioning plate 12 guides the pressure strip 15 to slide. The pressure strip 15 is constrained by the limit block 16 at the top of the guide rod 14 and is provided with continuous downward pressure by the spring 17. With the help of the handle 20, the material can be easily pressed to ensure neat cutting edges.

[0019] As a technical optimization of this utility model, the protective cover 10 is a rectangular cover structure with openings at both the rear and bottom ends, and the protective cover 10 is made of transparent material.

[0020] In this embodiment, the protective cover 10 is a rectangular transparent cover with openings at the rear and bottom. The transparent material allows the operator to clearly observe the working status of the cutting wheel 9 and the accumulation of debris without opening the protective cover, which ensures operational safety and greatly facilitates equipment operation monitoring and preliminary fault diagnosis.

[0021] As a technical optimization of this utility model, two positioning base plates 12 distributed in the front and back are fixedly connected to the upper end surface of the workbench 1, and the two positioning base plates 12 form a cutting groove 13 for avoiding the cutting wheel 9.

[0022] In this embodiment: two positioning base plates 12 are fixed on the worktable 1 to form a cutting groove 13, which provides a dedicated channel for the downward cutting movement of the cutting wheel 9, avoids the cutting wheel 9 from directly contacting the main body of the worktable 1, protects the worktable 1 from damage, ensures smooth cutting action and accurate cutting depth, and helps guide the raw material.

[0023] As a technical optimization of this utility model, two guide rods 14 distributed on the left and right are fixedly connected to the upper end face of the positioning base plate 12. Pressure strips 15 are slidably connected to the outer walls of the two guide rods 14. Limiting blocks 16 are fixedly connected to the top ends of the two guide rods 14. Springs 17 located between the limiting blocks 16 and the pressure strips 15 are sleeved on the outer walls of the guide rods 14. A handle 20 is fixedly connected to the upper end face of the pressure strips 15.

[0024] In this embodiment: a guide rod 14 with a limiting block 16 is provided on the positioning base plate 12, and a pressure strip 15 is slidably connected and pressure is provided by a spring 17. The pressure strip 15 has a handle 20. The elastic deformation of the spring 17 automatically adapts to raw materials of different thicknesses and provides a constant clamping force, which simplifies the positioning and clamping operation of the raw materials, ensures that the raw materials are stable and do not shift during cutting, guarantees the quality of the cut, and has strong adaptability.

[0025] As a technical optimization of this utility model, a connecting piece 11 is fixedly connected to the top of the protective cover 10, and the protective cover 10 is detachably connected to the front end face of the nut seat 5 through the connecting piece 11 and bolts.

[0026] In this embodiment, the protective cover 10 is detachably connected to the nut seat 5 via the top connecting piece 11 and bolts, realizing the modular connection between the protective cover 10 and the moving parts. This allows the protective cover 10 to move with the cutting unit as a whole, maintaining the continuity of protection. More importantly, the bolt connection facilitates the quick disassembly of the protective cover 10, greatly simplifying the operation of cleaning, maintaining or replacing the cutting tools inside the cutting wheel 9 and the protective cover 10.

[0027] As a technical optimization of this utility model, two slide rods 18 symmetrically distributed on both sides of the lead screw 4 are fixedly connected between the two shaft seats 3, and the nut seat 5 is slidably connected to the two slide rods 18.

[0028] In this embodiment: two shaft seats 3 are fixedly connected to slide rods 18 located on both sides of the lead screw 4, and nut seat 5 is slidably connected to slide rods 18. The slide rods 18 guide and constrain the nut seat 5, ensuring that the nut seat 5 can only move smoothly in a predetermined horizontal direction under the drive of the lead screw 4, eliminating the possibility of rotation or deviation, and improving the stability and accuracy of the cutting feed.

[0029] As a technical optimization of this utility model, a drive motor 19 is installed on the outer wall of one of the bearing seats 3, the output end of the drive motor 19 is fixedly connected to the lead screw 4, and a motor for driving the cutting wheel 9 to rotate is installed on the rear end face of the vertical section of the right-angle mounting seat 8.

[0030] In this embodiment: the drive motor 19 is mounted on the shaft seat 3 to drive the lead screw 4, and the cutting wheel 9 is driven by the motor mounted on the right-angle mounting seat 8, which respectively provides the power source for horizontal feed and tool rotation, realizing the precise and controllable movement of the cutting wheel 9 in the horizontal direction and its own high-speed rotation cutting function, providing a power basis for efficient and automated cutting.

[0031] The working principle and usage process of this utility model are as follows: Paper cup raw materials are laid flat on the workbench 1 and placed on the front and rear positioning base plates 12. The pressure strip 15 is lifted by the handle 20, and after aligning the front edge of the raw material with the positioning reference, the pressure strip 15 is lowered. The elastic force of the spring 17 pushes the pressure strip 15 downwards to automatically press the raw material. The equipment is started, and the drive motor 19 drives the lead screw 4 to rotate, causing the nut seat 5 to move horizontally along the slide rod 18 to the predetermined cutting start position. The electric push rod 6 extends according to the thickness of the raw material, pushing the mounting plate 7, the right-angle mounting seat 8, and the cutting wheel 9 down to the set cutting depth, so that part of the cutting wheel 9 enters the cutting groove 13. The drive motor of the cutting wheel 9 is started. The machine operates with the cutting wheel 9 rotating at high speed. The drive motor 19 restarts, driving the nut seat 5 and the entire cutting unit (including the cutting wheel 9 and the protective cover 10) to move horizontally along the slide bar 18 at a set path and speed. The high-speed rotating cutting wheel 9 continuously cuts the raw material that is stably pressed by the pressure strip 15 below, forming the required sheet material. The debris generated during the cutting process is effectively blocked by the transparent protective cover 10 and collected in its internal space. After the cutting is completed, the electric push rod 6 retracts and lifts the cutting wheel 9, and the drive motor 19 can reset the cutting unit. When cleaning or maintenance is required, the bolts can be loosened to remove the protective cover 10 for internal cleaning or to operate the cutting wheel 9.
