Accurate positioning and cutting not only improves efficiency, but also minimizes the waste of paper materials. The accuracy of the cutting process ensures the maximum utilization of paper and helps to reduce production costs. Through the linkage of the controller and multiple actuators (such as feeding mechanism, feed roller, positioning plate, push rod, etc.), the entire process of paper positioning and cutting is automatically completed, reducing manual intervention, improving production efficiency and automation level, and reducing operation complexity.
[0017] 3. The present invention proposes a cutting machine for processing PLA degradable paper cups. By rationally designing the layout of the receiving rod and baffle of the receiving assembly, the collection efficiency and convenience of the cut fan-shaped paper can be effectively improved. The arrangement of the receiving rod conforms to the shape of the fan-shaped cutting hole and can better adapt to the shape of the cut paper. By setting receiving rods at all four corners and arranging them rationally according to the characteristics of the inner and outer arcs, it is ensured that the paper can fall smoothly into the collection rack to avoid the paper from being scattered or stacked unevenly. By setting multiple receiving rods at both ends of the inner arc and below the middle position, the paper can be effectively prevented from sliding or dislocating due to gravity or external interference during the collection process. This design makes the collection rack more stable and can better accommodate the cut paper. The receiving collection rack adopts a fan-shaped design, which can collect the cut paper in an orderly manner to the designated position, which is convenient for subsequent removal. The reasonable spacing and stability of the design ensure that the paper is not easily damaged when it is taken out. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0026] See also Figure 1-Figure 2 and Figure 4-Figure 5 , this embodiment provides the following technical solutions:
[0027] A cutting machine for processing PLA degradable paper cups comprises a box body 1, wherein a feed inlet 101 is provided at one end of the box body 1, and the other end of the box body 1 is open so as to take out the cut fan-shaped paper 10, a guide roller 2 is provided on one side of the box body 1, and the guide roller 2 is close to the feed inlet 101, a controller 3 is provided at the front end of the box body 1, a cutting mechanism 4 is provided inside the box body 1, a positioning platen 5 is provided on one side of the cutting mechanism 4, a fixed template 6 is provided on one side of the positioning platen 5, and a material receiving component 7 is provided on one side of the fixed template 6, the cutting mechanism 4 comprises two cutting plates 404 of different sizes for facilitating the cutting of cups of different sizes, and further comprises an optical module 405, and the optical module 405 is electrically connected to the controller 3, the optical module 405 is located inside the cutting plate 404, the optical module 405 comprises a receiving end and a transmitting end, the receiving end is arranged near the transmitting end to ensure that a reflected light signal can be received, and an optical isolator is used between the receiving end and the transmitting end for optical shielding.
[0028] It also includes paper 10, which enters the box 1 through a feeding mechanism for cutting. A pattern area 1001 is printed on the paper 10, and an infrared marking pattern 1002 is arranged inside the pattern area 1001. The infrared marking pattern 1002 is a specific part of the pattern area 1001 of the paper 10, such as the logo, and an infrared reflective coating or material is added to form a specific mark.
[0029] Specifically, the paper 10 is continuously conveyed under the action of the feeding mechanism. When the pattern area 1001 moves to the position of the cutting hole 602, the transmitting end of the optical module 405 emits infrared light to illuminate the infrared marking pattern 1002 on the paper 10. The infrared marking pattern 1002 is reflective. The receiving end of the optical module 405 is used to receive the light reflected back by the infrared marking pattern 1002 and transmit the signal to the controller 3. The controller 3 controls the feeding mechanism and the first feed roller 8 and the second feed roller 11 to stop running, so that the pattern area 1001 corresponds to the position of the fan-shaped cutting hole 602 without offset, thereby ensuring the consistency and aesthetics of the pattern area 1001 and the paper cup molding effect.
[0030] In this embodiment, the cutting plate 404 is fixedly connected to the movable plate 403 through a connecting rod 406, a fixed plate 401 is provided on the side of the movable plate 403 away from the cutting plate 404, and the fixed plate 401 is fixedly connected to the box body 1, an electric push rod 1 402 is installed on the upper end of the fixed plate 401, and the electric push rod 1 402 is fixedly connected to the movable plate 403. A pressing hole 504 matching the cutting plate 404 is provided inside the positioning pressing plate 5, and a cutting hole 602 matching the cutting plate 404 is provided inside the fixed template 6.
[0031] Specifically, by driving the electric push rod 402, the movable plate 403 drives the connecting rod 406 and the cutting plate 404 to reciprocate, and the cutting plate 404 sequentially penetrates the pressing hole 504 and the cutting hole 602 to cut the paper 10 fixed between the positioning pressing plate 5 and the fixed template 6.
[0032] In this embodiment, the second feed roller 11 is installed at the upper and lower ends of the positioning pressure plate 5, the first feed roller 8 is installed at the upper and lower ends of the fixed template 6, and the first feed roller 8 and the second feed roller 11 rotate towards each other through a driving device, and a discharge plate 9 is arranged below the fixed template 6, and the discharge plate 9 is arranged at an angle and fixedly connected to the box body 1.
[0033] Specifically, through the cooperation of the first feed roller 8 and the second feed roller 11, it can be ensured that the paper 10 is evenly squeezed and pushed during the conveying process, and the accumulation or uneven sliding of the paper 10 can be effectively avoided, thereby greatly improving the conveying efficiency. The discharge plate 9 is set to an inclined state. This design can not only effectively guide the outflow of the paper 10, but also avoid the retention or jamming of the paper 10 during the discharge process, ensuring that the paper 10 flows smoothly into the subsequent processing links.
[0034] In this embodiment, an electric push rod 2 601 is provided on the fixed template 6, and the telescopic end of the electric push rod 2 601 is fixedly connected to the positioning pressure plate 5, and a guide rod 501 is provided on the positioning pressure plate 5, one end of the guide rod 501 is fixedly connected to the fixed template 6, and the other end of the guide rod 501 extends to the outside of the positioning pressure plate 5 and is connected to the limiting plate 502, and a spring 503 is provided on the outer wall of the guide rod 501, and the two ends of the spring 503 are respectively fixedly connected to the limiting plate 502 and the positioning pressure plate 5, by driving the electric push rod 2 601, the movement of the positioning pressure plate 5 can be controlled to make it approach the fixed template 6 and position the paper 10, combined with the structural design of the guide rod 501 and the limiting plate 502, it can ensure that the positioning pressure plate 5 is stable and straight during the movement, avoids offset or uneven positioning, thereby improving the positioning accuracy of the paper 10, and ensuring the accurate position of the paper 10 during the cutting process, and the spring 503 can effectively play a buffering role during the working process.
[0035] See also Figure 3 and Figure 6 In this embodiment, the material receiving assembly 7 includes a material receiving rod 701 and a baffle 702 , one end of the material receiving rod 701 is fixedly connected to the fixed template 6 , and the other end of the material receiving rod 701 is fixedly connected to the baffle 702 .
[0036] Specifically, receiving rods 701 are provided at the four corners of the fan-shaped cutting hole 602, wherein only one receiving rod 701 is provided at both ends of the outer arc of the fan-shaped cutting hole 602, two receiving rods 701 are provided at both ends of the inner arc, and another receiving rod 701 is provided below the middle position of the inner arc. The seven receiving rods 701 form a fan-shaped paper 10 collection rack to collect the cut fan-shaped paper 10 and facilitate taking it out.
[0037] The working principle of the above technical solution is:
[0038] 1. Paper feeding and positioning: The paper 10 printed with patterns is fed into the device through the feeding mechanism, and under the guidance of the guide roller 2, enters the cutting box 1 from the feeding port 101. The paper 10 first passes through the positioning platen 5 and the feeding roller group at the upper end of the fixed template 6. During the feeding process, the paper 10 enters between the positioning platen 5 and the fixed template 6 to ensure the stable positioning of the paper 10 during the cutting process;
[0039] 2. Pattern recognition and mark detection: When the paper 10 moves to the predetermined position, the pattern area 1001 begins to approach the cutting hole 602. At this time, the optical module 405 inside the cutting plate 404 starts to work, and the transmitting end of the optical module 405 emits infrared light to illuminate the infrared mark pattern 1002 on the paper 10. The infrared mark pattern 1002 is usually a special identification mark printed on the paper 10. The receiving end of the optical module 405 receives the reflected infrared light signal and transmits the received signal to the controller 3. In this way, the device can accurately locate the pattern area 1001 on the paper 10;
[0040] 3. Positioning and cutting preparation: According to the information fed back by the optical module 405, the controller 3 controls the feeding mechanism, the first feeding roller 8, and the second feeding roller 11 to stop running, ensuring that the pattern area 1001 and the cutting hole 602 are accurately aligned. The controller 3 also drives the electric push rod 2 601 to make the positioning plate 5 approach the fixed template 6, thereby accurately positioning the paper 10 and ensuring that it is stable and motionless;
[0041] 4. Cutting process: After the paper 10 is positioned, the controller 3 drives the electric push rod 402 to drive the movable plate 403, the connecting rod 406 and the cutting plate 404 to reciprocate. The cutting plate 404 is driven by the movable plate 403 to pass through the pressing hole 504 and the cutting hole 602 in sequence to cut the paper 10 positioned between the fixed template 6 and the positioning pressure plate 5. The cutting plate 404 accurately cuts out the fan-shaped area of the paper 10 to ensure high cutting accuracy each time;
[0042] 5. Paper collection and discharge: After cutting, the cut fan-shaped paper 10 will be directly pushed into the receiving assembly 7 for subsequent collection and removal. The paper 10 is guided to flow out through the feed roller group and the discharge plate 9 at the lower end of the positioning plate 5 and the fixed template 6, while avoiding the retention or jamming of the paper 10 during the discharge process, ensuring that the paper 10 flows smoothly into the subsequent processing link.
[0043] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
