Description
Technical Field
The utility model relates to the field of printers, in particular to a double-rubber-roll transmission structure for a printer.
Background
When a printer prints, a paper feeding rubber roller and a printing rubber roller are usually arranged to convey consumables in the printing process.
However, the existing double-rubber-roller transmission structure has great defects in the use process: 1) in the normal printing process, because the distance from the printing head to the paper outlet is long, particularly after a subsequent module is additionally arranged, the distance from the printing head to the paper outlet of the subsequent module is longer, so that blank consumable materials can appear before printing tasks start every time, and the utilization rate of the consumable materials is reduced; 2) because there are two rubber rolls in the transmission structure, the rotational speed between the two must not absolutely unanimous, at the printing in-process, under the condition that paper feed rubber roll rotational speed is less than or equal to printing rubber roll rotational speed, after the printing of certain time, can appear piling up of consumptive material to influence printing quality.
SUMMERY OF THE UTILITY MODEL
Utility model purpose: the utility model aims to provide a double-rubber-roller transmission structure for a printer, which solves the problems of the double-rubber-roller transmission structure in the using process.
The technical scheme is as follows: the utility model provides a double-rubber-roll transmission structure for a printer, which comprises an installation frame, a motor, a gear set transmission structure, a printing rubber roll structure and a paper feeding rubber roll structure, wherein the motor is arranged at one end of the installation frame; the gear set transmission structure comprises a first gear, a second gear, a third gear, a fourth gear, a fifth gear, a sixth gear, a seventh gear, an eighth gear and a ninth gear, wherein the first gear is connected with the motor shaft and is meshed with the second gear, the third gear is connected with the end part of the printing rubber roll structure and is meshed with the second gear, the fourth gear is arranged below the third gear and is meshed with the second gear, the fourth gear, the fifth gear and the sixth gear are sequentially arranged in parallel in a meshed manner, the seventh gear is arranged below the eighth gear in an inclined manner and is respectively meshed with the sixth gear, the ninth gear is arranged at the end part of the paper feeding rubber roll structure, and drives the paper feeding structure to rotate clockwise under the meshing action of the seventh gear when the printing rubber roll structure rotates clockwise, and drives the rubber roll structure to rotate clockwise under the meshing action of the eighth gear when the printing rubber roll structure rotates anticlockwise, the paper feeding rubber roller structure is driven to rotate anticlockwise.
