A die-cutting knife for cooperating with the die-cutting opening 42 for die-cutting is protruding from the bottom of the upper die base 5.
[0033] The four corners of the upper die seat 5 are vertically fixed with guide rods 51, which are installed on the top seat 2. The guide rods 51 can ensure that the upper die seat 5 will not be misaligned during the up and down adjustment process during operation.
[0034] Furthermore, a cleaning assembly 6 for assisting paper cleaning and pressing is installed on the side of the upper die seat 5. The cleaning assembly 6 includes a protruding block 13 symmetrically and vertically fixed at the middle section of the top of the upper die seat 5. A sliding cavity is opened on the protruding block 13. A sliding rod 14 is vertically fixed in the sliding cavity. A slider 16 is slidably arranged on the sliding rod 14. A hinge seat 17 is fixed on the outer side of the slider 16. A hinge plate 18 is symmetrically hingedly installed on the hinge seat 17. A rotating roller 7 is rotatably arranged between the two hinge plates 18. The outer edge of the rotating roller 7 is A cleaning brush 8 is protrudingly provided at the rotating roller 7, and the cleaning brush 8 is two sets of threads with opposite spiral directions. The cleaning brush 8 is protrudingly provided at the outer edge of the rotating roller 7. An air guide cavity is opened inside the rotating roller 7, and an air suction hole 9 is opened on the outer edge of the rotating roller 7.

[0035] Through the cleaning components 6 arranged on both sides of the upper die base 5, the hinged plate 18 is driven to be opened and the tension spring 19 is driven to be pulled open during the downward movement of the upper die base 5, and the slider 16 rises along the slide rod 14 and drives the compression spring 15 to be compressed as a whole. At the same time, the meshing gear plate 11 and the meshing gear 12 are meshed and transmitted, so that the meshing gear 12 rotates. During the rotation of the meshing gear 12, the rotating roller 7 is driven to rotate as a whole, and the cleaning brush 8 is driven to rotate as a whole. During the rotation of the cleaning brush 8, the impurities on the top of the paper are driven to perform auxiliary rotation cleaning. At the same time, during the downward movement of the upper die base 5, the hinged plate 18 is driven to be opened and the tension spring 19 is driven. The sliding block 16 is pulled open, and the sliding block 16 rises along the sliding rod 14 and drives the pressing spring 15 to be compressed as a whole. At the same time, the meshing tooth plate 11 and the meshing gear 12 are meshed and transmitted, so that the meshing gear 12 rotates. In the process of the meshing gear 12 rotating, the rotating roller 7 is driven to rotate as a whole, and the cleaning brush 8 is driven to rotate as a whole. In the process of the cleaning brush 8 rotating, the impurities on the top of the paper are driven to perform auxiliary rotation cleaning, so that before the upper die base 5 die-cutting, the overall downward pressure of the upper die base 5 can realize the stable rotation of the rotating roller 7 on the top of the paper and the subsequent dust suction cleaning, so as to avoid the impurities remaining adsorbed on the paper after cutting, causing the impurities to be adsorbed on the inner wall of the paper cup.
[0036] Meshing gears 12 are fixed at both ends of the rotating roller 7, and meshing tooth plates 11 are protrudingly provided on both sides of the lower mold base 4. The meshing tooth plates 11 are meshed with the meshing gears 12 for transmission.

Due to the obstruction of the concave part of the clamping groove 41, the rotating roller 7 cannot continue to push to both sides. At this time, the slider 16 rises along the slide rod 14 and drives the clamping spring 15 to be further compressed, thereby assisting in clamping the two ends of the paper, thereby avoiding the loosening of the paper as much as possible during the die-cutting process.
[0041] A method for using a die-cutting device comprises the following steps:
[0042] S1: Prepare the paper for die-cutting, and place the paper to be die-cut horizontally on the top of the lower die base 4;
[0043] S2: During the initial die-cutting operation, the hydraulic rod 22 drives the upper die base 5 to move downward as a whole, and in the process of the upper die base 5 moving downward, the rotating roller 7 is driven to move downward as a whole, and after the rotating roller 7 moves downward, the outer edge of the meshing gear 12 is attached to the top of the meshing gear plate 11;
[0044] S3: When the work continues, the upper die base 5 continues to move downward, and in the process of the upper die base 5 moving downward, the hinge plate 18 is pushed open and the tension spring 19 is pulled open, and at the same time, the slider 16 rises along the slide rod 14 and drives the compression spring 15 to be compressed as a whole, and at the same time, the meshing gear plate 11 and the meshing gear 12 are meshed and transmitted, so that the meshing gear 12 rotates, and in the process of the meshing gear 12 rotating, the rotating roller 7 is driven to rotate as a whole, and the cleaning brush 8 is driven to rotate as a whole, and in the process of the cleaning brush 8 rotating, the impurities on the top of the paper are driven to perform auxiliary rotation cleaning;
[0045] S4: Vacuuming work, during the cleaning process of the cleaning brush 8 rotating, the conduit 10 is connected to the vacuum cleaner, so that the suction hole 9 is sucked as a whole, and during the suction process of the suction hole 9, the impurities on the paper are driven to rotate and clean up, and can be stably sucked and filtered;
[0046] S5: Pressing process: As the hinged plate 18 continues to unfold, the rotating roller 7 is driven to unfold. When the rotating roller 7 reaches the pressing groove 41, the rotating roller 7 is pressed on the pressing groove 41. Due to the obstruction of the concave part of the pressing groove 41, the rotating roller 7 cannot continue to push to both sides. At this time, the slider 16 rises along the slide bar 14 and drives the pressing spring 15 to be further compressed, thereby assisting in pressing the two ends of the paper. At the same time, the upper die base 5 continues to press down, so that the die-cutting knife on the upper die base 5 assists in die-cutting the paper at the die-cutting opening 42 at the top of the lower die base 4, and then die-cuts a paper cup.
[0047] S6. During the die-cutting operation, the hydraulic rod 22 rises and the device is restored to its original state under the action of the stretched tension spring 19 and the compressed hold-down spring 15.
