Embodiment Construction

[0026] The principles and features of the present invention are described below, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0027] Such as figure 1 As shown, a paper driving device includes a driving roller 11, a pinch roller 2 and an adjustment mechanism 3, and the driving roller 11 and the pinch roller 2 are parallel to each other and are correspondingly arranged on both sides of the printing medium. The adjustment mechanism 3 includes a lever mechanism 31 and an adjustment drive mechanism 32, the pinch roller 2 is rotationally connected with one end of the lever mechanism 31, and the adjustment drive mechanism 32 drives the other end of the lever mechanism 31 to move and make the The pinch roller 2 is close to or away from the driving roller 11 .

[0028] Specifically, the printing medium may be printing paper, the base paper in a thermal transfer printer, or other printing medi...

Abstract

The invention relates to a paper feeding driving device and a printer comprising the same. The paper feeding driving device comprises a driving roller, a pressing roller and an adjusting mechanism, the driving roller and the pressing roller are mutually parallel and correspondingly arranged on two sides of a printing medium, the adjusting mechanism comprises a lever mechanism and an adjusting driving mechanism, the pressing roller is rotatably connected with one end of the lever mechanism, and the adjusting driving mechanism drives the other end of the lever mechanism to move and enables the pressing roller to be close to or far away from the driving roller. The paper feeding driving device and the printer comprising the same have the beneficial effects that the adjusting driving mechanism drives the pressing roller to press or be far away from the driving roller through the lever mechanism, so that the printing medium and the driving roller are pressed or loosened, the pressing roller presses the printing medium in the printing process, the driving roller provides power for moving the printing medium, the pressing roller is loosened when the printing medium needs to be withdrawn, the printing medium is withdrawn, and the power can be saved by reasonably setting the length ratio of force arms on the two sides of the fulcrum of the lever mechanism.

Description

technical field [0001] The invention relates to the field of printers, in particular to a paper-feeding driving device and a printer comprising the same. Background technique [0002] During the printing process of the printer, after the printing medium is printed, the printing medium needs to be provided with driving force during the traveling process. In the prior art, rotating rollers are usually arranged below or above the printing medium to drive the printing medium to move through friction, but this transmission method is prone to slipping and is unreliable. Contents of the invention [0003] The technical problem to be solved by the invention is how to drive the printing medium to move. [0004] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: a paper-feeding driving device, including a driving roller, a pinch roller and an adjustment mechanism, the driving roller and the pinching roller are parallel to ...
