Description

Printer output structure

technical field

The invention relates to a printer, in particular to a printer film output structure.

Background technique

A printer is a device used to print paper, film, etc. Printers that print film are mostly used in medical settings. The quality of film is heavier than that of paper. When outputting printed films, the printer needs to provide more Large output force.

A common printer on the market is shown in FIG. 1 , which includes a printer main body 1 on which a film outlet 2 for outputting films is opened. In order to support the film, a film output pallet 3 is provided at the film output port 2; after the film is printed and output, it is output from the film output pallet 3. However, because the quality of the film is significantly greater than that of the paper, the possibility of the film being stuck or difficult to be pushed out during the output of the film is greater than that of the paper.

Contents of the invention

The purpose of the present invention is to provide a printer film output structure, which can apply an external force to the film to drive the film output on the basis of the original film output by the printer, so as to bring out the printed film.

Above-mentioned technical purpose of the present invention is achieved through the following technical solutions:

A printer film output structure, comprising a printer main body and a film output port located on the printer main body. A transmission member for pushing the film out is also embedded on the sheet-out pallet.

By adopting the above-mentioned technical scheme, when the film is printed, the main body of the printer itself has the power to push the film out. The driving function facilitates the output of the film from the output pallet.

It is further provided that the transmission member is set as a roller hinged on the sheet-discharging pallet, the roller runs through the sheet-discharging pallet, and the diameter of the roller is larger than the thickness of the sheet-discharging pallet.

By adopting the above-mentioned technical scheme, during the operation of the transmission member, the roller rotates, and the film that interferes with the roller moves linearly with the rotation of the roller. The diameter of the roller is greater than the thickness of the supporting plate so that the roller must have a part protruding from the supporting plate, so as to interfere with the film.

It is further provided that a number of limit teeth are arranged on the sheet output pallet, and the tips of the limit teeth are set in a circular arc shape.

By adopting the above-mentioned technical scheme, when the film is outputting, when the film moves for a certain distance, the side of the film close to the main body of the printer will easily fall on the output pallet. Possibility of slipping back into the printer after full output.

It is further provided that the position-limiting teeth are arranged symmetrically on both sides of the sheet-discharging pallet, and the roller is located at the center of the sheet-discharging pallet.

By adopting the above technical solution, both sides of the film can be subjected to the same limit force; the location of the roller at the center of the film output pallet facilitates the transmission of the driving force applied to the film to various positions of the film.

Further setting: the side of the roller facing the film outlet and the side facing away from the film outlet are both provided with balls embedded in the side of the film output pallet facing away from the ground.

By adopting the above technical solution, the ball can reduce the frictional force between the film and the film output pallet, reducing the possibility of the film being worn.

Further setting: the roller is driven by a gear pair, the gear pair is meshed with the side of the ball facing the ground, the gear pair is located in the main body of the printer, the gear pair includes a driving wheel and at least one driven wheel, and the driving wheel is driven by rotation The device drives.

By adopting the above technical scheme, the rotation driving device rotates to drive the driving wheel, the driving wheel drives the driven wheel, and the driven wheel drives the roller, so as to realize the active rotation of the roller and drive the film.

It is further provided that a first transmission rod is connected to the output shaft of the rotary driving device, the driving wheel is passed through the first transmission rod, the driven wheel is passed through a second transmission rod, and the first transmission Both the rod and the second transmission rod are rotatably connected in the main body of the printer.

By adopting the above technical solution, during the rotation process, the relative position between the driving wheel and the driven wheel and the main body of the printer remains unchanged, and the effect of free rotation can be achieved.

It is further provided that the diameter of the driving wheel is smaller than that of the driven wheel.

By adopting the above technical solution, when the driving wheel rotates, the rotational speed of the driven wheel is lower than that of the driving wheel, thereby achieving the effect of deceleration.

It is further provided that: the end of the first transmission rod away from the output shaft and the two ends of the second transmission rod are provided with bearings, and the bearings are embedded in the main body of the printer.

By adopting the above technical solution, the bearing can reduce the frictional resistance caused by the driving wheel and the driven wheel during actual rotation.

As a preference, the main body of the printer is also provided with a lifting device for adjusting the inclination of the output pallet, and the lifting device includes a piston pushing device on the side facing the ground of the rotary drive device, and a piston pushing device on the side facing away from the ground of the output pallet. As for the elastic part on one side, an active groove is provided in the main body of the printer, and the ends of the first transmission rod and the second transmission rod both fall into the movable groove.

By adopting the above-mentioned technical scheme, adjusting the height of the piston pushing device can jack up the gear pair, and at the same time can jack up the sheet-discharging pallet, which plays a role in adjusting the inclination of the pallet.

To sum up, the present invention has the following beneficial effects: the film can be driven by the roller; the ball reduces the frictional resistance between the film and the film output pallet; the piston pushing device can also play the role of adjusting the height of the film output pallet.
