[0002] The structure of the commonly used printers is usually to set up an eccentric rotating guide shaft between the two side plates, install the carriage on the guide shaft, and then mount the print head on the carriage, when it is necessary to adjust the printing according to the thickness of the paper When adjusting the gap between the printing head and the printing roller, the guide shaft of the character car is usually rotated at a certain angle to drive the printing head to move up and down to achieve the purpose of adjustment. As a result, the printing accuracy of the printer is affected. At the same time, the rotation of the guide shaft of the character car requires a large torque, which requires a high-power motor

Embodiment Construction
[0014] refer to figure 1 , figure 2 , the first embodiment of the present invention, there are two upper and lower character car guide shafts 4, 41 passing through the long hole-shaped guide holes 5, 51 between the two side plates 20 in the printer, and the character car 3 is installed on the character car guide On the shaft, it can move back and forth in the up and down direction. The print head 1 is mounted on the character carriage 3, and the print head 1 cooperates with the printing roller 2 to complete the printing of characters on the printing paper. Bearing 6 and cylinder 6a are respectively fixed on the lower word car guide shaft 41, and the peripheral top of bearing 6 contacts with cam 7, and cam 7 has long diameter part and short diameter part, and long and short diameter part connects smoothly and forms cam curve. The lower part of the periphery of the drum 6a is connected to the lower part of the "L" shaped lever 8. The lever 8 is supported by a shaft 81 fixed on...

The invention discloses a printer; in the printers commonly used in the past, the guide shaft of the character carriage is usually rotated at a certain angle to drive the print head to move up and down, and the gap between the print head and the print roller is adjusted. The left and right yaw phenomenon will also occur while moving, which will affect the printing accuracy. At the same time, the rotation of the guide shaft of the character car also requires a large torque; the present invention adopts the upper and lower guide shafts of the car , the lower long guide hole passes through; or the guide shaft of the lower character car passes through the long guide hole opened on the side plate, the guide shaft of the upper character car is fixed on the two side plates, the upper part of the character car is equipped with a shaft, and the shaft is fixed by a sleeve frame, torsion spring and bearing, the bearing is set on the shaft installed on the fixed frame, and the fixed frame has a long guide hole that can move left and right relative to the shaft; the invention can adjust the print head and Print roller gap.
Description
technical field [0001] The invention relates to a printer, in particular to a printer capable of adjusting the gap between a printing head and a printing roller. Background technique [0002] The structure of the commonly used printers is usually to set up an eccentric rotating guide shaft between the two side plates, install the carriage on the guide shaft, and then mount the print head on the carriage, when it is necessary to adjust the printing according to the thickness of the paper When adjusting the gap between the printing head and the printing roller, the guide shaft of the character car is usually rotated at a certain angle to drive the printing head to move up and down to achieve the purpose of adjustment. Thereby the printing accuracy of the printer is affected, and at the same time, the rotation of the guide shaft of the character car requires a large torque, which requires a high-power motor. Contents of the invention [0003] In order to overcome the deficie...
