Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Examples

As shown in fig. 1 to 5, a leveling device for a feeding end of a printer comprises a printer body 1, wherein a paper placing plate 2 is arranged on the printer body 1, and a rotating assembly 3 is arranged on the paper placing plate 2;

the rotating assembly 3 comprises connecting plates 301 located on two sides of the paper placing plate 2, rotating grooves 302 are formed in the connecting plates 301, pressing rollers 304 are arranged between the connecting plates 301, two ends of each pressing roller 304 are rotatably connected with connecting shafts 303, and rotating shafts 305 fixedly connected with the rotating grooves 302 are slidably connected in one of the connecting shafts 303.

As shown in fig. 1, fig. 2, fig. 3 and fig. 4, furthermore, the equal fixedly connected with lagging 5 in both sides of putting cardboard 2, set up and two fixedly connected with springs 7 in the lagging 5 is embedded, the spring 7 other end and connecting plate 301 bottom fixed connection, make the setting of accessible spring 7, when the paper is more, when thickness is higher, drawing of accessible spring 7 rises, make compression roller 304 can improve the height, be convenient for adapt to the different thickness of paper, and simultaneously, spring 7 still can make compression roller 304 laminate with the upper surface of paper, be convenient for increase certain pressure to the paper.

As shown in fig. 3 and 4, a bolt 8 is further slidably connected to one side of the other connecting plate 301 through the connecting shaft 303, so as to fix the connecting shaft 303 in the connecting plate 301, that is, fix the pressing roller 304.

As shown in fig. 1, 2, 3 and 5, a handle 6 is further fixedly connected to one end of the latch 8 located outside the connecting plate 301, so as to facilitate taking the latch 8.

As shown in fig. 1, fig. 2 and fig. 3, further, a rubber layer 4 is sleeved outside the pressing roller 304, so that a certain friction force is generated between the pressing roller 304 and the paper, and the wrinkled paper can be rolled out better.

The working principle is as follows: when the paper feeding device is used, a user pulls the bolt 8 through the handle 6 to separate the bolt 8 from the connecting shaft 303 at one end, so that the connecting shaft 303 at one end is separated from the corresponding connecting plate 301, then the pressing roller 304 is rotated to separate the surface of the pressing roller 304 from the upper surface of the paper placing plate 2, the required paper can be placed on the paper placing plate 2, then the pressing roller 304 is rotated to recover the paper and restore the bolt 8, the connecting shaft 303 is fixed on the connecting plate 301, at the moment, if the height of the paper is higher, the lower end of the pressing roller 304 is in contact with the paper to drive the connecting shaft 303 to move upwards, the connecting plate 301 is driven to move upwards in the sleeve plate 5, the spring 7 is stretched, the tension force of the spring 7 can form a certain pressure on the paper, at the moment, the end with the wrinkles of the paper is placed at one end of the pressing roller 304, the printer is started, a paper feeding roller of the printer works, and the paper enters the paper feeding roller, the rotation of the pressing roller 304 can be driven, so that the folded paper can be flattened by the pressing roller 304, and the phenomenon of blocking caused again when the paper enters the paper conveying roller can be avoided.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
