[0030] In the specific implementation process, Figure 1 As shown, the full-cut structure of the printer includes a reduction gear set 2 respectively mounted on a mounting frame 1, a driving assembly 3 for driving the reduction gear set 2 to rotate, a cutter pressure gear 4 and a full-cut assembly. The reduction gear set 2 is meshed with the cutter pressure gear 4, and the full-cut assembly is driven to rotate when the cutter pressure gear 4 rotates.
[0031] Specifically, refer to Figure 3 As shown, the driving assembly 3 includes a damping gear set, a micro motor 22 and a main gear 23. The micro motor 22 is fixedly mounted on the mounting frame 1. The output end of the micro motor 22 is fixedly connected to the main gear 23, and the main gear 23 is meshed with the damping gear set.
[0032] refer to Fig.10 As shown, the damping gear set includes a large end gear 24, a small end gear 25, a torsion spring and a fixed rod 9. The fixed rod 9 is fixedly mounted on the mounting frame 1. The large end gear 24 and the small end gear 25 are rotatably mounted on the outer surface of the fixed rod 9 respectively. The large end gear 24 and the small end gear 25 are connected by a torsion spring, and the torsion spring is sleeved on the outer surface of the fixed rod 9.
[0033] The main gear 23 is driven to rotate by the micro motor 22, and the main gear 23 transmits power to the damping gear set, and the damping effect is achieved by the clamping force of the torsion spring. When the torsion spring torque increases to the clamping state, the large end gear 24 idles, and the torque will not be transmitted to the small end gear 25. When the torsion spring torque increases to the clamping state, the large end gear 24 drives the small end gear 25 to rotate, and drives the knife pressure gear 4 to rotate through the reduction gear set 2.
[0034] It should be noted that a push block is fixed to the bottom of the knife pressing gear 4, and the push block drives the full-cutting assembly to rotate.
[0035] refer to Figure 5-Figure 9 As shown, the full-cut assembly includes a full-cut push rod 5, a paper flying assembly 6, a full-cut blade 7, and a torsion spring lever 8 for driving the paper flying assembly 6 to rotate. The full-cut blade 7 is rotatably mounted on the mounting frame 1 through a shaft 26. An elastic reset member 10 is provided at one end of the full-cut blade 7. A connecting column 11 is inserted into the slot at the other end of the full-cut blade 7. One side of the full-cut blade 7 extends outward and is fixed with a connecting plate 12. The connecting plate 12 is fixedly connected to one end of the full-cut push rod 5. The top of the connecting column 11 is connected to one end of the torsion spring lever 8. When the pressure cutter gear 4 rotates counterclockwise, the push block at the bottom of the pressure cutter gear 4 presses down the full-cut push rod 5 of the full-cut cutter assembly, and drives the full-cut blade 7 to rotate clockwise to complete the full-cutting action of the printing paper.
[0036] In a specific embodiment, reference Figure 4-Figure 9 As shown, the flying paper assembly 6 includes a flying paper mounting seat 13, a flying paper mounting cover 14 and a flying paper gear set. The flying paper mounting seat 13 is fixed to one side of the mounting frame 1, and the flying paper mounting cover 14 is movably mounted on the top of the flying paper mounting seat 13. The flying paper gear set is located in the flying paper mounting cover 14. A driving column 15 is provided at the bottom of the flying paper mounting cover 14. When the torsion spring lever 8 rotates, the flying paper gear set is driven to rotate.
[0037] Specifically, the flying paper gear set includes a rotating shaft 16, a connecting shaft 17, a flying paper wheel 18 and a small rubber wheel 19. The rotating shaft 16 and the connecting shaft 17 are respectively rotatably mounted in the flying paper mounting cover 14. The outer surface of the rotating shaft 16 is sleeved with a power torsion spring 20. One end of the power torsion spring 20 is against one end of the torsion spring lever 8. The rotating shaft 16 and the connecting shaft 17 are driven by gears. The flying paper wheel 18 is fixedly mounted on the outer surface of the connecting shaft 17. The small rubber wheel 19 is rotatably mounted on the flying paper mounting seat 13, and the small rubber wheel 19 is positioned with the flying paper wheel 18. Corresponding to the position, the torsion spring pull rod hooks the driving column 15 at the bottom of the flying paper installation cover 14, and compresses the power torsion spring 20 counterclockwise and drives the flying paper wheel 18 to rotate clockwise. After the torsion spring pull rod rotates a corresponding angle, the pull rod hooks the flying paper installation cover 14 to move forward and makes the flying paper wheel 18 press the small rubber wheel 19. When the flying paper installation cover 14 continues to move forward, the guiding inclined surface on the flying paper installation seat 13 presses down the torsion spring limit position to make it separate from the torsion spring pull rod. The torsion spring quickly resets and drives the flying paper wheel 18 to rotate counterclockwise quickly to bring the cut paper out to complete the flying paper action.
[0038] A mounting bracket 21 is also provided at the bottom of the flying paper mounting seat 13. The two ends of the elastic reset member 10 are respectively connected to one end of the full-cut blade 7 and one end of the mounting bracket 21. One end of the mounting bracket 21 matches the blade end of the full-cut blade 7. It should be noted that the elastic reset member 10 is preferably a tension spring. Under the action of the restoring force of the tension spring, the consumables stuck on the full-cut blade 7 can be popped outward, thereby preventing the consumables from sticking to the full-cut blade 7.
[0039] The working principle provided by the utility model is as follows: when the device is used, the main gear 23 is driven to rotate by the micro motor 22, and the main gear 23 transmits power to the damping gear set, and the damping effect is achieved by the clamping force of the torsion spring. In the process of the torsion spring torque increasing to the clamping state, the large end gear 24 idles, and the torque will not be transmitted to the small end gear 25. When the torsion spring torque increases to the clamping state, the large end gear 24 drives the small end gear 25 to rotate, and drives the pressure cutter gear 4 to rotate through the reduction gear set 2. When the pressure cutter gear 4 rotates counterclockwise, the push block at the bottom of the pressure cutter gear 4 presses down the full-cut push rod 5 of the full-cutting knife assembly, and drives the full-cutting blade 7 to rotate clockwise to complete the full-cutting action of the printing paper.
[0040] When the full-cut blade 7 rotates, the slot at one end of the full-cut blade 7 clamps the connecting column 11 with the torsion spring pull rod, driving the torsion spring pull rod to rotate together, and the torsion spring pull rod hooks the driving column 15 at the bottom of the flying paper installation cover 14, and compresses the power torsion spring 20 counterclockwise and drives the flying paper wheel 18 to rotate clockwise. After the torsion spring pull rod rotates a corresponding angle, the pull rod hooks the flying paper installation cover 14 to move forward and makes the flying paper wheel 18 press the small rubber wheel 19. When the flying paper installation cover 14 continues to move forward, the guiding inclined surface on the flying paper installation seat 13 presses down the torsion spring limit position to make it disengage from the torsion spring pull rod, and the torsion spring quickly resets and drives the flying paper wheel 18 to rotate counterclockwise quickly to bring the cut paper out to complete the flying paper action.
