Problems solved by technology

[0002] The transmission mechanism of the printer is used to drive the corresponding printing roller to rotate, thereby driving the paper forward. In the traditional printer, by increasing the pressure of the printing head relative to the roller, when the roller is driven, it will form a pulling force on the paper, pulling the paper, and the traditional printer It can only control the advance of the paper, but cannot control the advance speed of the paper roll at the end of the shaft. In addition, in the traditional printer, the control accuracy of the paper transmission is low, and it is easy to cause the printing paper to be skewed, jammed, etc., and the printing reliability is low, and the paper is returned. Unable to rewind the unrolled paper

Embodiment Construction

[0028] Embodiments of the present invention are described in detail below in conjunction with accompanying drawings:

[0029] Such as Figure 1-4 As shown, the printer of the present invention includes a housing 100, a transmission structure (not shown in the figure) respectively located in the housing 100, a fixed frame 101, and a rotating shaft 102, and the fixed frame 101 is provided with a paper feeding channel 200, the paper feeding channel 200 is provided with paper feeding pressure rollers (not shown in the figure), and the transmission structure is respectively connected to the rotating shaft 102 and the paper feeding pressure rollers.

[0030] The transmission structure of the printer described in the present invention is not only connected to the paper feed roller, but also to the rotating shaft 102. When the paper feed roller moves forward or reverse, the rotating shaft 102 moves forward or reverse synchronously, and the paper roll In the process of entering the pr...

Abstract

The invention discloses a printer, which comprises a casing, a transmission structure, a fixing frame and a rotating shaft respectively located in the casing, a paper feeding channel is arranged in the fixing frame, and a paper feeding pressure roller is arranged in the paper feeding channel. The transmission structure is respectively in transmission connection with the rotating shaft and the paper-feeding pressure roller. The transmission structure of the printer described in the present invention is not only connected with the transmission of the paper feeding roller, but also with the rotating shaft at the same time. When the rotating shaft, the paper inlet of the fixed frame, and the area to be printed enter the printing area, the transmission structure can control the paper feeding roller and the rotating shaft to move synchronously in the forward or reverse direction, which can overcome the speed of the paper end of the rotating shaft in the prior art. It can be seen that the transmission control effect of the printer roll paper in the present invention is good, the quality of the printer is reliable, and the printing quality of the roll paper is high.

Description

technical field [0001] The invention relates to the technical field of roll paper printing, in particular to a printer. Background technique [0002] The transmission mechanism of the printer is used to drive the corresponding printing roller to rotate, thereby driving the paper forward. In the traditional printer, by increasing the pressure of the printing head relative to the roller, when the roller is driven, it will form a pulling force on the paper, pulling the paper, and the traditional printer It can only control the advance of the paper, but cannot control the advance speed of the paper roll at the end of the shaft. In addition, in the traditional printer, the control accuracy of the paper transmission is low, and it is easy to cause the printing paper to be skewed, jammed, etc., and the printing reliability is low, and the paper is returned. Unable to rewind the unrolled paper. Contents of the invention [0003] Based on this, the present invention overcomes the ...
