Description

Technical Field

[0001] The utility model relates to the technical field of rotating shafts, in particular to a torque limiter sliding clutch damping rotating shaft. Background Art

[0002] In order to convert electronic information files into paper information files, a printer is often needed. A printer is one of the output devices of a computer and is used to print the results of computer processing on relevant media. There are three indicators to measure the quality of a printer: print resolution, print speed and noise. There are many types of printers. Depending on whether the printing element has an impact on the paper, they are divided into impact printers and non-impact printers. According to the structure of printed characters, they are divided into full-width character printers and dot matrix character printers. According to the way a line of characters is formed on paper, they are divided into serial printers and line printers. According to the technology used, there are cylindrical, spherical, inkjet, thermal, laser, electrostatic, magnetic, light-emitting diode and other printers.

[0003] Currently, all printers have a paper feed mechanism, which usually uses a paper feed rotating shaft to feed paper. However, since the paper feed rotating shaft is generally directly connected to the motor, when the torque generated by the paper feed rotating shaft is too large, the paper feed rotating shaft cannot be overload protected, which can easily cause damage to the paper feed rotating shaft. For this reason, we propose a torque limiter sliding clutch damping shaft. Utility Model Content

[0004] The purpose of the utility model is to provide a torque limiter sliding clutch damping shaft. By setting a damping shaft structure, a rotating sleeve and a fixing ring are assembled with a spring and its fixed base, and then the rotating sleeve is connected to the paper feed rotating shaft. When the paper feed rotating shaft generates a large torque, the entire damping shaft structure will slip, thereby providing overload protection for the paper feed rotating shaft.

[0005] To achieve the above-mentioned object, the present utility model provides the following technical solutions: a torque limiter sliding clutch damping shaft, comprising a damping shaft structure, wherein the damping shaft structure is composed of a fixed ring, a spring, a fixed base and a rotating sleeve;

[0006] The spring is sleeved on the outer surface of the rotating sleeve, and the rotating sleeve is inserted into the interior of the fixed base;

[0007] One end of the rotating sleeve passes through the middle of the fixed base and is fixedly connected to the fixed ring.

[0008] Preferably, the fixed base includes a base sleeve, a first mounting circular groove opened at one end of the base sleeve, and a second mounting circular groove opened at the other end of the base sleeve.

[0009] Preferably, the rotating sleeve includes a connecting sleeve plugged into the interior of the base sleeve, a connecting ring fixedly connected to one end of the connecting sleeve, and two grooves opened on one side of the connecting ring.

[0010] Preferably, the connecting ring is located inside the first installation circular groove, and the fixing ring is located inside the second installation circular groove.

[0011] Preferably, the fixed base further includes two connecting protrusions, the two connecting protrusions are connected to the end surface of the base sleeve, and the connecting protrusions and the base sleeve are integrally formed.

[0012] Technical effects and advantages of this utility model:

[0013] The entire damping shaft structure is assembled by putting the spring on the rotating sleeve, then inserting the rotating sleeve into the fixed base, and then connecting the fixed ring to the rotating sleeve. The paper feed rotating shaft of the printer is then passed through the rotating sleeve, and the paper feed rotating shaft is connected to the rotating sleeve. The fixed base is connected to the output end of the motor, and the damping shaft structure and its paper feed rotating shaft are driven to rotate by the motor. When the paper feed rotating shaft generates a large torque, slippage occurs between the rotating sleeve and the fixed base, thereby providing overload protection for the paper feed rotating shaft.
