Description

Sign feeding rubber roller mechanism of sign printer

Technical Field

The utility model relates to a sign printer field, more specifically say, relate to a sign rubber roll mechanism is advanced to sign printer.

Background

In the prior art, the sign feeding rubber rollers of the sign printer are all of cylindrical structures, and when the signs are conveyed, the rubber rollers are always in a rotating state, so that when all the signs to be printed are stacked together and conveyed, all the signs can continuously enter, no gap exists between the signs, equipment only can recognize the continuous signs as one sign, and therefore continuous printing of multiple signs cannot be realized. Meanwhile, when a plurality of labels are stacked and printed, due to the accumulation of the weight of the labels, the labels generate great friction with a conveying plane in the conveying process, so that the rubber roller possibly slips in the conveying process, namely the conveying distance of the labels is smaller than the rotating length of the rubber roller.

Disclosure of Invention

The to-be-solved technical problem of the utility model lies in providing a tablet rubber roll mechanism is advanced to sign printer, can realize advancing the tablet in-process in succession and let and produce the clearance between sign and the sign.

The utility model provides a technical scheme that its technical problem adopted is: the structure provides a tablet rubber roll mechanism is advanced to sign printer, including advancing the tablet rubber roll, advance the tablet rubber roll and be equipped with the bellying and the gentle portion that the interval set up in turn on the surface, the bellying is greater than the distance of flat portion of slowing and advancing between the tablet rubber roll the central axis apart from advancing tablet rubber roll central axis, when advancing the tablet rubber roll and rotate and send the sign, the bellying contacts with the sign, and flat portion of slowing and sign contactless.

In the above scheme, the protruding portion is provided with four sections, and the central angle corresponding to each section of protruding portion is 30 °.

In the above scheme, the convex part is provided with four sections, and the central angle corresponding to each section of the gentle part is 60 degrees.

In the above scheme, the arc diameter corresponding to the convex part is 20 mm.

In the scheme, the arc diameter corresponding to the flat part is 18 mm.

In the above scheme, the device further comprises a front auxiliary roller and a rear auxiliary roller, wherein the front auxiliary roller is higher than the rear auxiliary roller.

Implement the utility model discloses a sign rubber roll mechanism is advanced to sign printer has following beneficial effect:

1. the utility model designs some gaps on the outer surface of the cylindrical rubber roller to form a convex part and a flat part, so that the contact between the outer surface of the rubber roller and the label is intermittent, thereby ensuring that the label is paused for a certain time in the process of conveying, so that a gap is formed between the label and the label, and the machine can conveniently identify a plurality of labels;

2. the utility model discloses a set up two supplementary rollers and become rolling friction with carrying the planar sliding friction with the sign, effectively reduced the sign and carried the frictional force between the plane.

Drawings

The invention will be further explained with reference to the drawings and examples, wherein:

FIG. 1 is a schematic structural view of a card feeding rubber roller;

FIG. 2 is a cross-sectional view of the card feed roller;

fig. 3-5 are flow charts of the label feeding rubber roller mechanism of the label printer for conveying labels;

fig. 6 is a schematic view of the front auxiliary roller and the rear auxiliary roller.

Detailed Description

In order to clearly understand the technical features, objects, and effects of the present invention, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown in fig. 1-2, the utility model discloses a sign printer advances tablet rubber roll mechanism, including advancing tablet rubber roll 1. The tile feeding rubber roller 1 is provided with protruding parts 2 and flat buffering parts 3 which are alternately arranged at intervals on the surface, the distance between the protruding parts 2 and the central axis of the tile feeding rubber roller 1 is larger than the distance between the flat buffering parts 3 and the central axis of the tile feeding rubber roller 1, when the tile feeding rubber roller 1 rotates to convey a sign 4, the protruding parts 2 are in contact with the sign 4, and the flat buffering parts 3 are not in contact with the sign 4.

The boss 2 is the arc, and it is provided with four sections, and every section boss 2 corresponds central angle is 30, and the circular arc diameter that the boss 2 corresponds is 20mm, can bulge when rotating and carry plane 7, can carry sign 4. The boss 2 is provided with four sections, the central angle corresponding to each section of the flat and gentle portion 3 is 60 degrees, the diameter of the arc corresponding to the flat and gentle portion 3 is 18mm, the circular arc cannot protrude out of the conveying plane 7 when the circular arc rotates, and the label 4 cannot be conveyed.

As shown in fig. 3-5, after one label 4 is completely separated from the card feeding rubber roller 1, the label 4 above the label 4 falls off, because the card feeding rubber roller 1 rotates, the lower part of the label 4 is a flat part 3, and the label 4 stops in the conveying process, so that a gap is formed between adjacent labels in the conveying process.

Further, a front auxiliary roller 5 and a rear auxiliary roller 6 are included, and the front auxiliary roller 5 is higher than the rear auxiliary roller 6. The angle of the tangent line at the top of the front auxiliary roller 5 and the rear auxiliary roller 6 to the conveying plane 7 is 0.6 °. When the label 4 is conveyed forwards, the gravity of the label 4 generates a component force in the conveying direction to help the label 4 roll forwards; meanwhile, the original sliding friction of the label 4 is changed into rolling friction, so that the friction coefficient is reduced, and the force required by the rubber roller for conveying the label 4 is effectively reduced.

While the embodiments of the present invention have been described with reference to the accompanying drawings, the present invention is not limited to the above-described embodiments, which are merely illustrative and not restrictive, and many modifications may be made by one skilled in the art without departing from the spirit and scope of the present invention as defined in the appended claims.
