Specific embodiments

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0025] Refer to Figures 1-5, A cutting machine for processing PLA degradable paper cups, including a base 1. A support column 2 is fixedly connected to the outer wall of the top of the base 1. A first support plate 3 and a third support plate 24 are fixedly connected to the outer wall of the top of the support column 2. A bidirectional screw 7 is rotatably connected to the first support plate 3. A first motor 8 is fixedly connected to the top of the third support plate 24 by screws. The output end of the first motor 8 is fixedly connected to one end of the bidirectional screw 7. A connecting plate 5 and a fixing plate 9 are respectively threadedly connected to the bidirectional screw 7. The connecting plate 5 and the fixing plate 9 are symmetrically located on both sides of the bidirectional screw 7. A connecting block 11 is fixedly connected to the outer wall of the fixing plate 9. A suction hole 12 is opened on the outer wall of the connecting block 11. An air pump 14 is provided on the outer wall of the first support plate 3. The air pump 14 is communicated with the suction hole 12 through an air vent hose 13. A through hole 17 is provided inside the first support plate 3. A cutting knife 6 is provided on the connecting plate 5. The first motor 8 drives the connecting plate 5 and the fixing plate 9 to move in opposite directions by driving the bidirectional screw 7, so that the cutting knife 6 and the connecting block 11 move in opposite directions, making the cut paper complete and without damage.

[0026] In the cutting machine for processing PLA degradable paper cups of the present utility model, a telescopic rod 4 is fixedly connected to the outer wall of the connecting plate 5, and the other end of the telescopic rod 4 is fixedly connected to the first support plate 3. A fixing block 10 is connected through the fixing plate 9, and the other end of the fixing block 10 is fixedly connected to the first support plate 3. The installed telescopic rod 4 and fixing block 10 can prevent the connecting plate 5 and the fixing plate 9 from rotating when the bidirectional screw 7 rotates.

[0027] In the cutting machine for processing PLA degradable paper cups of the present utility model, the through hole 17 matches the structure and size of the cutting knife 6, and the cutting knife 6 matches the structure and position of the connecting block 11, which can enable the cutting knife 6 and the connecting block 11 to move in opposite directions smoothly.

[0028] In the cutting machine for processing PLA degradable paper cups of the present utility model, a support block 18 is fixedly connected to the outer wall of the top of the support column 2. A hollow groove is opened on the support block 18. A rotating shaft 19 is provided on the hollow groove. A paper roll 21 is nested on the rotating shaft 19, which can enable the rotating shaft 19 to rotate smoothly on the hollow groove.

[0029] In the cutting machine for processing PLA degradable paper cups of the present utility model, a second motor 20 is installed on one side outer wall of the support block 18. The output end of the second motor 20 is fixedly connected to the rotating shaft 19. The second motor 20 can drive the rotating shaft 19 to rotate, and then make the paper roll 21 rotate.

[0030] A cutting machine for processing PLA degradable paper cups of the present utility model. A conveying roller 15 and a paper winding roller 16 are rotatably connected to the outer wall of the first support plate 3. A driving motor is provided on the paper winding roller 16. A second support plate 22 is fixedly connected to the top outer wall of the support column 2. A first paper pressing wheel 23 is provided on the second support plate 22. A second paper pressing wheel 25 is provided on the outer wall of the third support plate 24. By installing the paper winding roller 16, the cut waste paper can be wound up, facilitating the further processing of the waste paper by the staff. The installed paper pressing wheels can play a role in limiting the paper.

[0031] A cutting machine for processing PLA degradable paper cups of the present utility model. A rectangular tube 27 is fixedly connected to the outer wall of the first support plate 3. A rectangular groove is opened on the rectangular tube 27. The connecting block 11 is located inside the rectangular tube 27. The fixing plate 9 is fitted and connected with the rectangular groove. A finished product storage box 26 is provided on the top outer wall of the base 1. The discharging end of the rectangular tube 27 corresponds to the opening end of the finished product storage box 26. By installing the finished product storage box 26 and the rectangular tube 27, the cut paper will not float randomly in the air and can smoothly enter the finished product storage box 26.

[0032] In the present utility model, when the paper needs to be cut, first install the paper roll 21 and the rotating shaft 19 on the support block 18, and then start the second motor 20 to rotate, driving the rotating shaft 19 to rotate. Since the rotating shaft 19 is embedded inside the paper roll 21, the rotating shaft 19 will drive the paper roll 21 to rotate, making the head of the paper first enter the first paper pressing wheel 23 fixedly connected to the top of the second support plate 22, which plays a role in limiting the paper, and then enter the second paper pressing wheel 25 fixedly connected to the top of the third support plate 24, which plays a role in limiting the paper again. Then it enters the conveying roller 15. After passing through the cutting knife 6, at this time, turn on the first motor 8, so that the output end of the first motor 8 drives the bidirectional screw rod 7 to rotate. Since the connecting plate 5 is fixedly connected with the telescopic rod 4 and the fixing plate 9 is penetrated and connected with the fixing block 10, the connecting plate 5 and the fixing plate 9 will not rotate, and the bidirectional screw rod 7 is threadedly connected with the connecting plate 5 and the fixing plate 9. Therefore, the bidirectional screw rod 7 will drive the connecting plate 5 and the fixing plate 9 to move in opposite directions. Since the cutting knife 6 is provided on the connecting plate 5, the connecting block 11 is provided on the fixing plate 9, and the suction hole 12 is provided on the connecting block 11, the cutting knife 6 will move in the opposite direction to the suction hole 12, and the suction hole 12 is communicated with the air pump 14 fixedly connected to the first support plate 3 through the ventilation hose 13. When the cutting knife 6 moves towards the suction hole 12 and the suction hole 12 contacts the paper cut by the cutting knife 6, the suction hole 12 will suck the paper to the surface of the suction hole 12. When the suction hole 12 moves away from the cutting knife 6, the suction hole 12 will lose the attraction force, making the paper do a free fall movement inside the rectangular tube 27 and finally fall into the finished product storage box 26. The waste paper generated after cutting will be wound up by the paper winding roller 16, facilitating the further processing of the waste paper by the staff.

[0033] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
