Abstract
Disclosed is a printer transmission mechanism, comprising a support, wherein the support is provided with a driving motor, a transmission gear, a first synchronization gear, a second synchronization gear, a first drive roller, and a second drive roller; the driving motor comprises an output shaft; the output shaft is provided with an output gear; the output gear is engaged with the transmission gear simultaneously engaged with the first synchronization gear and the second synchronization gear; the tooth number of the first synchronization gear is equal to that of the second synchronization gear. and the first drive roller and the second drive roller are respectively connected with the first synchronization gear and the second synchronization gear. The printer transmission mechanism of the utility model is capable of improving the operation reliability of a printer and allowing the control over the printing paper conveniently.
Description
Technical field
The utility model relates to a kind of printer transmission mechanism.
Background technology
When printer is printed, needs control printing paper advances or retreats, the existing practice is: drive a driven roller by drive motors and rotate, and then the drive printing paper advances, but existing printer is low to the control accuracy of printing paper, the situations such as printing paper is crooked, paperboard often occur, the reliability of printer work is low, can't control easily the paper feed of printer and move back paper simultaneously.
Summary of the invention
Based on this, the utility model is to overcome the defective of prior art, and a kind of printer transmission mechanism is provided, and the utility model can improve the functional reliability of printer, and can control printing paper easily.
Its technical scheme is as follows:
A kind of printer transmission mechanism, comprise support, be provided with drive motors, travelling gear, the first synchromesh gear, the second synchromesh gear, the first driven roller and the second driven roller at support, drive motors includes output shaft, this output shaft is provided with output gear, output gear and travelling gear engagement, travelling gear meshes with the first synchromesh gear, the second synchromesh gear simultaneously, the number of teeth of the first synchromesh gear, the second synchromesh gear equates that the first driven roller, the second driven roller are connected with described the first synchromesh gear, the second synchromesh gear respectively.
The below describes further technical scheme:
Described travelling gear comprises the first train of reduction gears, the second train of reduction gears and third wheel, the first train of reduction gears, the second train of reduction gears include driving tooth and driven tooth, the number of teeth of driving tooth is more than the number of teeth of driven tooth, the driving tooth engagement of output gear and the first train of reduction gears, the driving tooth engagement of the driven tooth of the first train of reduction gears and the second train of reduction gears, the driven tooth of the second train of reduction gears and third wheel engagement.
The axial connecting line level of described the first synchromesh gear, the second synchromesh gear.
The below describes advantage or the principle of aforementioned techniques scheme:
1, when printer is worked, drive motors drives the first synchromesh gear, the rotation of the second synchromesh gear by output gear, travelling gear, the first synchromesh gear equates with the rotating speed of the second synchromesh gear, so that the first driven roller, the second driven roller rotate synchronously, printing paper is by the first driven roller, when the second driven roller drives, it moves more reliable, can realize easily the paper feed of printing paper and move back paper, and printing paper is difficult for crooked and paperboard;
2, travelling gear comprises the first train of reduction gears, the second train of reduction gears and third wheel, can realize slowing down by the first reduction gearing and the second reduction gearing, makes the printer paper feed and move back paper more steady;
3, the axial connecting line level of described the first synchromesh gear, the second synchromesh gear can guarantee that printing paper is in the state of basic horizontal.
