Abstract
A paper feeding mechanism of a paper sheet printer comprises a plurality of rubber rollers, wherein the rubber rollers are sequentially arranged in parallel along the horizontal direction, and a synchronous transmission mechanism is arranged between the rubber rollers; the cross section of each rubber roller is in a gear shape when being seen from the cross section vertical to the central axis of the rubber roller. The utility model discloses the during operation, the scraps of paper are put on the rubber roll, because the surface of rubber roll is formed with the tooth's socket, therefore big with scraps of paper coefficient of friction, scraps of paper self has great weight, can rub the scraps of paper with the hands simultaneously by many rubber rolls in addition, consequently can drive the paper and advance fast and the phenomenon of skidding can not appear, improve the speed of form advancing, do not receive the restriction of scraps of paper thickness moreover.
Description
Technical Field
The utility model belongs to the technical field of printing apparatus, concretely relates to paper feeding mechanism of scraps of paper printer.
Background
The common printing stocks such as labels, identifiers, product labels, tickets, product serial codes, two-dimensional codes, business cards and the like can be printed by using a paper printer, and the paper printer is not necessarily limited to printing paper printing stocks and can also be used for printing sheet printing stocks made of other materials such as plastic sheets and the like.
During printing, the paper printer needs to push the paper forward by the paper feeding mechanism. Most traditional paper feeding mechanism adopts a rotating rubber roller to naturally place paper sheets on the rubber roller, however, the paper feeding mode has the following defects: when the printing speed is high and the paper feeding speed is high, the paper feeding speed is limited due to the slip phenomenon on the surfaces of the paper sheets and the rubber rollers.
In order to improve the paper feeding speed, people also design a clamping and conveying mode of an upper rubber roller and a lower rubber roller or an upper conveying belt and a lower conveying belt, namely, the upper rubber roller 1 and the lower rubber roller 1 which rotate pinch the paper sheets 3 to advance as shown in figure 1, or the upper conveying belt 5 and the lower conveying belt 5 which rotate pinch the paper sheets 3 to advance as shown in figure 2, and the defects of the paper feeding mode are as follows: 1. because the paper feeding mechanism adopts upper and lower double-layer rubber rollers or upper and lower conveying belts, the vertical size of the occupied space of the paper feeding mechanism is large, and the arrangement of the whole machine is influenced; 2. the vertical clearance between the upper and lower rubber rollers (or the upper and lower conveyer belts) is fixed or adjusted inconveniently, so that the paper slip roller is difficult to adapt to paper slips with different thicknesses.
SUMMERY OF THE UTILITY MODEL
An object of the present invention is to overcome the above disadvantages and to provide a paper feeding mechanism for a paper sheet printer, which is fast in paper feeding speed and free from the limitation of the thickness of paper sheets.
The purpose can be realized according to the following scheme: a paper feeding mechanism of a paper sheet printer comprises a plurality of rubber rollers and is mainly characterized in that the number of the rubber rollers is multiple, the rubber rollers are sequentially arranged in parallel along the horizontal direction, and a synchronous transmission mechanism is arranged between the rubber rollers; the cross section of each rubber roller is in a gear shape when being seen from the cross section vertical to the central axis of the rubber roller.
The synchronous transmission mechanism is a synchronous belt.
The utility model has the advantages of it is following and effect:
one, the utility model discloses the during operation, the scraps of paper are put on the rubber roll, because the surface of rubber roll is formed with the tooth's socket, therefore big with scraps of paper coefficient of friction, scraps of paper self has great weight (relative paper), can rub the scraps of paper by many rubber rolls simultaneously in addition, consequently can drive the paper and advance fast and the phenomenon of skidding can not appear, improve the speed of form advancing.
And secondly, because a clamping and conveying form is not needed, the device is not limited by the thickness of the paper sheets, saves the space of the device and is beneficial to reducing the volume of the printer.
Drawings
Fig. 1 is a schematic view showing an operating state of a sheet feeding mechanism of a conventional first sheet printer.
Fig. 2 is a schematic view showing an operating state of a sheet feeding mechanism of a conventional second sheet printer.
Fig. 3 is a schematic view of the working state of the embodiment of the present invention.
Fig. 4 is a schematic view of the structure of the rubber roller in fig. 3.
Detailed Description
Fig. 3 and 4 show a paper feeding mechanism of a paper sheet printer, which includes three rubber rollers 1, each rubber roller 1 is arranged in parallel in sequence along the horizontal direction, a synchronous belt 2 is arranged between each rubber roller 1 for synchronous transmission, a tooth groove 10 is formed on the surface of each rubber roller 1, and the extending direction of the tooth groove 10 is parallel to the central axis direction of the rubber roller 1; the cross-sectional shape of each rubber roller 1 is gear-shaped when viewed from a cross-section perpendicular to the central axis of the rubber roller 1, as shown in fig. 4.
In the above embodiment, the number of the rubber rollers can be changed to four, or two, and so on.
In the above embodiment, the synchronous transmission of the gears can be changed among the rubber rollers.
Claims (2)
1. The utility model provides a paper feeding mechanism of scraps of paper printer, includes the rubber roll, its characterized in that: the rubber rollers are sequentially arranged in parallel along the horizontal direction, a synchronous transmission mechanism is arranged between the rubber rollers, a tooth groove is formed on the surface of each rubber roller, and the extending direction of the tooth groove is parallel to the direction of the central axis of the rubber roller; the cross section of each rubber roller is in a gear shape when being seen from the cross section vertical to the central axis of the rubber roller.
2. A paper feeding mechanism for a paper sheet printer according to claim 1, characterized in that: the synchronous transmission mechanism is a synchronous belt.
