[0003] The existing patent (publication number: CN210308098U) discloses a feeding device for a circular knife die cutting machine, which relates to the technical field of die cutting machines. The feeding device for a circular knife die cutting machine includes a substrate, a motor, and an air shaft assembly, and further includes a longitudinal displacement adjusting mechanism for adjusting the longitudinal displacement of the air shaft assembly. The longitudinal displacement adjusting mechanism includes a mounting plate and a lead screw for driving the mounting plate to move longitudinally. The lead screw is threadedly installed on the substrate, and a rotating bearing is provided on the mounting plate. The lead screw passes through the substrate and is fixedly installed in the rotating bearing.

[0030] Please refer to Figure 1 、 Figure 2 and Figure 3 In this embodiment, an upper discharging mechanism of a circular knife film cutting machine includes a machine body 1. A first rotating rod 2 is rotatably connected to the inner wall of the machine body 1. First threaded grooves 3 are formed at the other ends of the first rotating rod 2. The two first threaded grooves 3 are symmetrical. Two sliding members 4 are provided inside the machine body 1. The two sliding members 4 are threadedly connected to the first threaded grooves 3 close to them respectively. Elastic scraping plates 5 are fixedly connected to the bottom surfaces of the two sliding members 4. A second rotating rod 6 is rotatably connected to the inner wall of the machine body 1. Second threaded grooves 20 are formed at both ends of the second rotating rod 6. The two second threaded grooves 20 are symmetrical. Two correcting frames 7 are provided inside the machine body 1. The two correcting frames 7 are threadedly connected to the second threaded grooves 20 close to them respectively. By installing the correcting frames 7, the materials can be limited, so that they can be conveyed within a limited range. And through the cooperation of the sliding members 4 and the elastic scraping plates 5, the materials can be combed to avoid the materials from shifting or stacking together, thereby improving the stability of material conveying.

[0031] Please refer to Figure 1 、 Figure 2 and Figure 3, on the inner wall of the machine body 1, a material air shaft 8 and a waste air shaft 9 are installed. Installing the waste air shaft 9 can collect waste materials, facilitating their recycling. On the inner wall of the machine body 1, a conveying mechanism 10 is installed. The conveying mechanism 10 is driven by an external motor. Installing the conveying mechanism 10 can facilitate the conveying of materials. At the same time, the inner wall of the conveying mechanism 10 is in contact with the machine body 1, which can prevent the impact force from damaging the conveying mechanism 10 when cutting the materials. A rotating column 11 is rotatably connected to the inner wall of the machine body 1. A servo motor 12 is installed on the back of the machine body 1. The output end of the servo motor 12 is fixedly connected to the rear end of the rotating column 11. A cam 13 is fixedly connected to the outer surface of the rotating column 11. A shearing member 14 is provided inside the machine body 1. The shearing member 14 is in contact with the cam 13. A belt and pulley drive connection is arranged between the first rotating rod 2 and the rotating column 11. Installing the cam 13 and the shearing member 14 can cooperate to cut the materials, and after cutting, the waste air shaft 9 can collect the waste materials. The upper surface of the shearing member 14 is set as an arc-shaped protrusion. The upper surface of the shearing member 14 being set as an arc-shaped protrusion can facilitate its contact with the cam 13 and cut the materials on the conveying device under the push of the cam 13. Two sliding rods 17 and two springs 18 are fixedly connected to the upper surface of the shearing member 14. Both of the two sliding rods 17 are slidably inserted into the machine body 1. The other ends of the two springs 18 are fixedly connected to the inner wall of the machine body 1. Installing the springs 18 can drive the shearing member 14 to reset through the deformation force of the springs 18, enabling it to separate the materials and facilitating the conveying of the materials.

[0032] Please refer to Figure 1 , Figure 2 and Figure 3 , two auxiliary rods 15 are fixedly connected to the inner wall of the machine body 1. Limiting members 16 are fixedly connected to the sides of the two correcting frames 7. Both of the two limiting members 16 are in contact with the auxiliary rods 15 close to them. Installing the auxiliary rods 15 can limit the materials, enabling the materials to be in a horizontal state and facilitating the cutting of the materials. Two shock-absorbing members 19 are fixedly connected to the bottom surface of the machine body 1. Both of the two shock-absorbing members 19 are made of rubber. Installing the shock-absorbing members 19 can reduce the vibration generated when the machine body 1 works and reduce the noise generated by the vibration.

[0033] The upper discharging mechanism of a circular cutting film machine in this embodiment can limit the materials by installing the correcting frame 7, enabling them to be conveyed within a limited range, and can comb the materials through the cooperation of the sliding member 4 and the elastic scraper 5, preventing the materials from shifting or stacking together, thereby improving the stability of material conveying.

[0034] It should be noted that the waste air shaft 9 is driven by an external motor.

[0035] The working principle of the above embodiments is as follows: First, the external motor starts to rotate the waste air shaft 9 to wind up the waste. During this process, the material air shaft 8 can be driven to rotate to release the material. At this time, the correction frame 7 can be adjusted by rotating the second rotating rod 6 so that the correction frame 7 can limit the material, enabling it to be conveyed within a limited range and making the material more stable. At this time, the servo motor 12 starts and drives the rotating column 11 to rotate. During the rotation of the rotating column 11, the first rotating rod 2 can be driven to rotate through the belt. During the rotation of the first rotating rod 2, two elastic scraping plates 5 can be driven to comb the material through the cooperation of the first thread groove 3, avoiding the deviation or stacking of the material, thereby improving the stability of material conveyance. The combed material passes through the two auxiliary rods 15, and the installation of two limit members 16 can improve the stability of material conveyance. When the rotating column 11 rotates, the shear member 14 can slide up and down in the machine body 1 and shear the material through the push of the cam 13 and the cooperation of the spring 18. The sheared material can be discharged through the conveying mechanism 10, and the waste is collected by the waste air shaft 9 for easy recycling and utilization.
