Description

An anti-jamming structure of a cardboard printing die-cutting machine

technical field

The invention relates to the technical field of a cardboard printing die-cutting machine, and more particularly relates to an anti-jamming structure of a cardboard printing die-cutting machine.

Background technique

At present, during the working process of our printing machine, when the cardboard is conveyed from the paper feeding platform to the vacuum box by the paper feeding tire, the cardboard must pass through a set of paper pulling rollers and then be sent to the small paper feeding wheel. The vacuum box needs a large vacuum negative pressure to suck the cardboard, and the small paper feed wheel can continuously convey the cardboard; but there must be a gap between the paper pulling roller and the vacuum box guide plate to prevent interference and wear paper roll. But in this way, when printing relatively thin cardboard, the thin cardboard will occasionally be sucked into the vacuum box by vacuum suction, causing paper jams. Paper jams can seriously reduce customer productivity; it can also increase product scrap rates.

Contents of the invention

In order to overcome at least one of the above-mentioned defects in the prior art, the present invention provides an anti-jam structure for a cardboard printing and die-cutting machine, which can completely eliminate paper jams, improve production efficiency, effectively reduce product scrap rate, and reduce labor costs.

In order to solve the above-mentioned technical problems, the technical solution adopted by the present invention is: an anti-jamming structure of a cardboard printing and die-cutting machine, including a paper feeding platform, from which the cardboard enters the die-cutting machine, and also includes a puller for transferring the cardboard. The lower paper roller and the upper paper pull roller, the other side of the lower paper pull roller and the upper paper pull roller are provided with a small paper feed wheel, and the upper part of the small paper feed wheel is provided with a vacuum box;

Wherein, the anti-jamming structure further includes a paper guide plate, and the paper guide plate and the paper-drawing upper roller are embedded into a shuttle-shaped structure.

In the present invention, both the paper-drawing upper roller and the paper-guiding plate are made into a shuttle structure, and the two parts can be inserted into each other without interference, which is equivalent to connecting the paper-drawing upper roller and the paper-guiding plate as a In one piece, there is no gap, thus eliminating the phenomenon of paper jams. This structure also does not affect the function of the vacuum box to absorb the cardboard and continuously feed paper.

Further, the paper guide plate is a plate-shaped structure, and the edge of the paper guide plate is fitted with the upper roller of the drawing paper.

The paper guide plate is entirely set on the side of the paper upper roller, and the two are inserted into each other, which is equivalent to connecting the paper upper roller and the paper guide plate as a whole, without gaps, thereby eliminating the phenomenon of paper jams.

Further, the paper pulling upper roll includes an upper roll main body, and upper roll grooves are arranged between each upper roll main body;

The edge of the paper guide plate is provided with a paper guide convex part, and each paper guide convex part is provided with a paper guide concave part, the main body of the upper roller is embedded in the concave part of the paper guide, and the convex part of the paper guide is embedded in the concave part of the upper roller. in the slot.

Through the cooperation of the above structures, the paper-drawing upper roller and the paper-guiding plate are integrated into one body, and there is no gap.

Further, the small paper feed roller is installed in the paper guide plate.

Compared with the prior art, the beneficial effect is that the present invention makes both the paper-drawing upper roller and the paper guide plate into a shuttle structure, and these two parts can be inserted into each other without interfering, which is equivalent to putting The paper-drawing upper roller is integrated with the paper guide plate, and there is no gap, thereby eliminating the phenomenon of paper jams. This structure also does not affect the function of the vacuum box to absorb the cardboard and continuously feed paper.

It can improve production efficiency, effectively reduce product scrap rate, and reduce labor costs.

detailed description

The accompanying drawings are for illustrative purposes only, and should not be construed as limitations on this patent; in order to better illustrate this embodiment, certain components in the accompanying drawings will be omitted, enlarged or reduced, and do not represent the size of the actual product; for those skilled in the art It is understandable that some well-known structures and descriptions thereof may be omitted in the drawings. The positional relationship described in the drawings is for illustrative purposes only, and should not be construed as a limitation on this patent.

As shown in Figures 1-5, an anti-jamming structure of a cardboard printing die-cutting machine includes a paper feeding platform 1 from which cardboard 7 enters the die-cutting machine, and also includes a paper puller for conveying cardboard 7 The roller 2 and the paper-drawing upper roller 3, the other side of the paper-drawing lower roller 2 and the paper-drawing upper roller 3 are provided with a small paper feed wheel 4, and the upper part of the small paper feed wheel 4 is provided with a vacuum box 6;

Wherein, the anti-jamming structure further includes a paper guide plate 5, and the paper guide plate 5 and the paper pulling upper roller 3 are embedded into a shuttle-shaped structure.

In this embodiment, the paper guide plate 5 is a plate-shaped structure, and the edge of the paper guide plate 5 is fitted with the upper roller 3 for drawing paper. The paper guide plate 5 is entirely arranged on the side of the paper-drawing upper roller 3, and the two are inserted into each other, which is equivalent to connecting the paper-drawing upper roller and the paper guide plate as a whole, without gaps, thereby preventing paper jamming.

Specifically, the paper pulling upper roller 3 includes an upper roller main body 31, and an upper roller groove 32 is arranged between each upper roller main body 31;

The edge of the paper guide 5 is provided with a paper guide protrusion 51, and each paper guide protrusion 51 is provided with a paper guide recess 52, the upper roller main body 31 is embedded in the paper guide recess 52, and the paper guide protrusions 51 is embedded in the upper roller groove 32. The small paper feed roller 4 is installed in the paper guide plate 5 .

During normal operation, the cardboard 7 is conveyed to the lower roller 2 and the upper roller 3 by the tire on the paper feeding platform 1, and then the lower roller 2 and the upper roller 3 relay the cardboard to the small paper feeding roller. Wheel 4, forming continuous paper feeding. And when the printing die-cutting machine is printing relatively thin cardboard, when the cardboard 7 passes through the paper-drawing lower roller 2 and the paper-drawing upper roller 3, it will occasionally be sucked by the vacuum negative pressure between the paper-drawing upper roller 3 and the paper guide plate 5. Suction into the vacuum box 6, causing paper jams.

In this embodiment, both the paper-drawing upper roller 3 and the paper guide plate 5 are made into a shuttle structure, and these two parts can be inserted into each other without interfering, which is equivalent to the paper-drawing upper roller and the guide plate 5. The cardboard is connected as a whole, there is no gap, thus eliminating the phenomenon of paper jam. This structure also does not affect the function of the vacuum box to absorb the cardboard and continuously feed paper.
