Detailed Description
The present invention will be described in further detail below with reference to the accompanying drawings by way of examples, which are illustrative of the present invention and are not intended to limit the present invention.
Referring to fig. 1 to 4, the unidirectional rotation gear set mechanism for a printer of the present embodiment includes a first gear 1 and a second gear 2, the first gear 1 is rotatably disposed on a first shaft 7 fixed to a printer frame 5, one end of a driving plate 6 is rotatably disposed on the first shaft 7 at a certain angle, the other end of one end of the driving plate 6 is rotatably disposed with the second gear 2, and the first gear 1 is engaged with the second gear 2.
The product is applied to a transmission part of a continuous printer, and aims to obtain the effect that after the printer continues to print, the printing paper is retracted by the reverse rotation of the driving shaft part, so that the printing head prints on the top of the printing paper, and the phenomenon that a ribbon shaft cannot synchronously reverse is avoided, thereby ensuring the improvement of the printing effect,
specifically, the product is introduced into a printer, wherein a first gear 1 is meshed with a driving gear 3 of a printer driving shaft, a second gear 2 is meshed with a ribbon gear 4 of a ribbon shaft, in a paper discharging state, due to the fact that the driving gear 3 rotates clockwise, the first gear 1 rotates anticlockwise synchronously to drive the second gear 2 to rotate clockwise, due to the fact that the first gear 1 is meshed with the second gear 2, the first gear 1 rotates to act on gear teeth of the second gear 2 to give a leftward tangential force to the gear teeth of the second gear 2, and due to the fact that a driving plate 6 is in rotating connection with a first shaft body 7, the driving plate 6 is driven to deflect towards the left side, so that the second gear 2 is meshed with the ribbon gear 4 to drive the ribbon gear 4 to rotate, when printing is completed, the ribbon gear 4 needs to be kept to not rotate, the driving gear 3 rotates to drive the paper outlet roller to rotate, the printing paper is driven to retract for a certain distance, the paper is restarted, the first gear 1 synchronously rotates clockwise to drive the second gear 2 to rotate anticlockwise, the first gear 1 is meshed with the second gear 2, the first gear 1 rotates to act on the gear teeth of the second gear 2 to give a right tangential force to the gear teeth of the second gear 2, the driving plate 6 is rotatably connected with the first shaft body 7 and is used for driving the driving plate 6 to deflect to the right side, the second gear 2 is deviated from the ribbon gear 4, the second gear 2 is separated from being meshed with the ribbon gear 4, the ribbon gear 4 is kept to be not rotated (namely, the ribbon is not rotated), the driving gear 3 rotates to drive the printing paper to retract for a certain distance, the ribbon is not easy to damage, and the service life of the printer is prolonged.
In this embodiment, the drive plate 6 is rotated by 5 ° to 8 ° on the first shaft 7, in a specific structure, the second gear 2 is rotatably disposed on the drive plate 6 through the second shaft 9, the second shaft 9 is slidably disposed on the arc-shaped shaft hole 8 of the printer frame 5, an arc center of the arc-shaped shaft hole 8 coincides with a rotation axis of the drive plate 6, an arc center angle of the arc-shaped shaft hole 8 is 5 ° to 8 °, and the drive plate 6 is rotated within an angle of 5 ° to 8 ° by the limitation of the arc-shaped shaft hole 8 in the structure.
In this embodiment, one end of the connecting plate 10 is fixedly connected to the first shaft, the other end of the connecting plate 10 is rotatably connected to a driving shaft of the printer, and the connecting plate 10 is fixed to the first shaft through a fastening bolt 11.
