Embodiment Construction

[0027] refer to figure 2 and image 3 As shown, the present invention discloses a card discharge structure for a thermal printer with a cutter, which includes a cutter gear 3, a cutter reset ratchet gear 32, a retracting pawl 4, and a retracting ratchet that can move relative to the cutter gear 3. Knife pull bar 6, cutter reset ratchet gear 32 is coaxially connected to cutter gear 3, knife retract pawl 4 is connected to retract knife pull bar 6, and both retract knife pull rod 6 and knife retract ratchet 4 are connected with a reset device. Under the effect of 6, the knife retraction pawl 4 engages 32 with the cutter reset ratchet gear.

[0028] refer to Figure 4 As shown, the above-mentioned card row structure is connected on the base 1 of the moving knife group, the cutter gear 3 is rotatably connected on the base 1, and the cutter gear 3 is connected with a driving shaft 31 matching the moving knife group 2, and the motor drives the cutter When the knife gear 3 rotates...

Abstract

The invention relates to a stuck eliminating structure of a thermal printer with a cutter, the structure comprises a cutter gear, a cutter reset ratchet, a retract pawl and a retract pull rod which can move relative to the cutter gear, the cutter reset ratchet is coaxially connected with the cutter gear, the retract pawl is connected with the retract pull rod, the retract pull rod and the retract pawl are connected with a reset device, and the retract pawl is engaged with the cutter reset ratchet under the function of the retract pull rod. According to the invention, the retract pull rod is driven by outside force, the retract pawl is driven by the retract pull rod, so that the retract pawl is engaged with the cutter reset ratchet and pushes the cutter reset ratchet to rotate in reverse direction, then the cutter gear coaxially connected with the cutter reset ratchet is driven to realize retract action, when the driving force disappears, the retract pull rod turns back to an initial position under the function of the reset device, the retract pawl turns back to the initial position under the function of the reset device and the retract pull rod, and fast feed-retract switching of a moving cutter group is realized.

Description

technical field [0001] The invention relates to the field of printers, in particular to a card discharge structure of a thermal printer with a cutter. Background technique [0002] At present, most thermal printers are equipped with a cutter, and after the thermal print head completes the printing work, the paper is cut by the cutter. When the cutter is cutting paper, it is inevitable that the cutter will be stuck. For the situation of the cutter being stuck, the traditional ways of retracting the knife with a thermal movement with a cutter on the market are as follows: [0003] The blade drive wheel is external, and the user manually toggles the reset method of the external drive wheel, such as figure 1 As shown, the cutter reset ratchet gear C connected to the blade set a includes an outer part C1 and a screwdriver cross groove C2 in the middle. The reset gear C rotates with the gear train during normal operation. When a knife jam occurs, the knife can be retracted by tu...
