Detailed Description
Referring to fig. 2 and 3, the invention discloses a card arranging structure of a thermal printer with a cutter, which comprises a cutter gear 3, a cutter resetting ratchet gear 32, a retracting pawl 4 and a retracting pull rod 6 capable of moving relative to the cutter gear 3, wherein the cutter resetting ratchet gear 32 is coaxially connected with the cutter gear 3, the retracting pawl 4 is connected with the retracting pull rod 6, the retracting pull rod 6 and the retracting pawl 4 are both connected with a resetting device, and the retracting pawl 4 is meshed with the cutter resetting ratchet gear 32 under the action of the retracting pull rod 6.
Referring to fig. 4, the above-mentioned card arranging structure is connected to the base 1 of the movable knife group, the cutter gear 3 is rotatably connected to the base 1, the cutter gear 3 is connected to a driving shaft 31 cooperating with the movable knife group 2, when the motor drives the cutter gear 3 to rotate, the driving shaft 31 drives the movable knife group 2 to move, so as to cooperate with the fixed knife group 10 to realize the cutting motion. When the cutter is jammed, the cutter can be withdrawn through the cooperation of the cutter withdrawal pull rod 6, the cutter withdrawal pawl 4 and the cutter resetting ratchet gear 32.
The retracting lever 6 is connected to the base 1, and the retracting lever 6 is movable relative to the base 1, so that the retracting lever 1 is also movable relative to the cutter gear 3. The reset device on the retracting pull rod 6 can be realized by a reset spring 7, one end of the reset spring 7 is fixed on the base 1, and the other end is connected on the retracting pull rod 6. When external force is applied to the retracting pull rod 6, the retracting pull rod 6 can compress or stretch the return spring 7 thereof, so that the return spring 7 generates elastic potential energy; when the external force disappears, the elastic potential energy of the return spring 7 can act on the retracting pull rod 6, so that the retracting pull rod 6 returns to the initial position.
The reset device of the tool retracting pawl 4 can be realized through a reset spring 5, the tool retracting pawl 4 is connected to a tool retracting pull rod 6, and when the tool retracting pull rod 6 moves relative to the base 1 and the cutter gear 3, the tool retracting pawl 4 also moves relative to the base 1 and the cutter gear 3. The tool retracting pawl 4 is provided with a ratchet, under the action of external force and the tool retracting pull rod 6 and the return spring 5, the ratchet of the tool retracting pawl 4 transversely moves and longitudinally moves towards the cutter gear 3 to be meshed with the ratchet of the cutter returning ratchet gear 32, the cutter returning ratchet gear 32 is reversely rotated, and therefore the cutter gear 3 is driven to reversely rotate, and tool retracting action of the movable cutter group 2 is achieved. When the external force disappears, the tool retracting pull rod 6 returns to the initial position under the action of the return spring 7, and simultaneously drives the tool retracting pawl 4 to transversely move, and the return spring 5 of the tool retracting pawl 4 enables the tool retracting pawl 4 to longitudinally move, so that the tool retracting pawl 4 returns to the initial position. That is to say, when the retracting pawl 4 resets along with the retracting pull rod 6, the retracting pawl 4 elastically bounces off the cutter resetting ratchet gear 32; when the retracting pawl 4 retracts along with the retracting pull rod 6, the elastic force of the return spring 5 enables the retracting pawl 4 to be meshed with the cutter return ratchet gear 32, and the repeated application of external force can realize multiple retracting actions.
The arrangement clamping structure can further comprise an external shifting block 15, the shifting block 15 is connected with the retracting pull rod 6, external force can be directly applied to the retracting pull rod 6 through the shifting block 15, the shifting block 15 also has a limiting effect, and the moving distance of the retracting pull rod 6 is limited.
Referring to fig. 4 to 8, the card arranging structure may further include a movement main body set 13, a shift lever 8 and a retracting rotary handle rod 9, the shift lever 8 and the retracting rotary handle rod 9 are disposed on a side surface of the movement main body set 13, the shift lever 8 is provided with a shift portion 81 acting on the retracting rotary handle rod 9 and a reset device, and the reset device may be implemented by using a torsion spring 12. The tool retracting rotary handle rod 9 is provided with a connecting part 91, the tool retracting pull rod 6 is provided with a bending part 61, and the connecting part 91 is matched with the bending part 61 to realize the connection of the tool retracting rotary handle rod 9 and the tool retracting pull rod 6. The shifting rod 8 is rotated, the shifting part 81 thereof is pulled outwards to drive the tool retracting rotating handle rod 9, the tool retracting rotating handle rod 9 drives the tool retracting pull rod 6, and the tool retracting pull rod 6 drives the tool retracting pawl to realize the single tool retracting movement. When the driving force disappears, the shift lever 8 is reset under the potential energy of the torsion spring 12. The uncovering rotary deflector rod 8 is repeatedly poked in this way, so that multiple retracting movements can be realized until the movable knife group 2 returns to the initial position.
The above-mentioned deflector 8 has a rotation portion 83, the rotation portion 83 can be connected with the lid-opening rotation handle 14, the rotation portion 83 of the deflector 8 is driven by the lid-opening rotation handle 14 to rotate, and the deflector 8 is driven to rotate.
The fixed cutter set 10 is connected to the core main body set 13, the fixed cutter set 10 is provided with a rubber roller bearing 102 connected to the core main body set 13, and the shift lever 8 can be provided with an ejection part 82 matched with a disengagement force-bearing part 101 of the fixed cutter set 10. The push-out part 82 of the shift lever 8 pushes out the releasing stress part 101 of the fixed cutter group 10 upwards in the rotation process, so that the rubber roller bearing 102 is released from the clamping part of the machine core main body group 13, and the rubber roller fixed cutter group 10 is quickly separated from the machine core main body group 13.
Because the rubber roller cutter fixing group is fixedly arranged on the cover opening 11 of the terminal equipment such as a POS machine and the like, the combination of the card discharging action and the cover opening action can be realized when the cutter clamps the cutter.
The key point of the invention is that the retracting pull rod 6 is driven by external force, then the retracting pull rod 6 drives the retracting pawl 4 to move, so that the retracting pawl 4 is meshed with the cutter resetting ratchet gear 32 and pushes the cutter resetting ratchet gear 32 to rotate reversely, thereby driving the cutter gear 31 coaxially connected with the cutter resetting ratchet gear 32 to realize retracting action, when the driving force disappears, the retracting pull rod 6 returns to the initial position under the action of the resetting device, the retracting pawl 4 returns to the initial position under the action of the resetting device and the retracting pull rod 6, namely, the retracting pawl 4 is quickly meshed with and separated from the cutter resetting ratchet gear 32, so that the quick switching between the feeding and retracting of the movable cutter group 2 is realized.
The above description is only exemplary of the present invention and is not intended to limit the technical scope of the present invention, so that any minor modifications, equivalent changes and modifications made to the above exemplary embodiments according to the technical spirit of the present invention are within the technical scope of the present invention.
