Furthermore, the terms "first," "second," and the like, are used for descriptive purposes only and are not to be construed as indicating or implying a relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature. In the description of the present utility model, the meaning of "a plurality" is two or more, unless explicitly defined otherwise.

Examples

As shown in fig. 1 to 5, the present embodiment provides a slitting knife device including: the automatic paper feeding device comprises a driving roller 1 and a driven roller 2 arranged right below the driving roller 1, wherein a plurality of driving cutters 11 are arranged on the driving roller 1 at equal intervals, a plurality of gaskets 21 are arranged on the driven roller 2 at equal intervals, knife grooves 22 are formed between the gaskets 21 in an abutting mode, the driving cutters 11 are arranged right above the knife grooves 22, the gaskets 21 and the driving cutters 11 are staggered, the situation that the driving cutters 11 cut the gaskets 21 is avoided, the gaskets 21 are arranged on the driven roller 2 through fixing pieces 23, namely the driven roller 2 drives the gaskets 21 to rotate together, the fixing pieces 23 are preferably in threaded connection, the disassembly is convenient, the fixing effect is good, the thickness and the width of the gaskets 21 are adjustable, namely the size of paper plates can be guaranteed by replacing different gaskets 21 according to actual production needs, the gaskets 21 can not only be cut on the driven roller 2, but also can be cut paper plates with different thicknesses and different widths, and the operation is simple and convenient to use.

The sum of the length of the knife slot 22 and the length of the gasket 21 is equal to the distance between the adjacent driven knives, so that the sizes of the paperboards of each cut part are the same, and the situation that the paper boxes are different due to different sizes and the using look and feel and experience are affected is avoided.

Meanwhile, the driving knife 11 is arranged on the driving roller 1 through the knife holder 12, the knife holder 12 is fixedly connected to the driving roller 1 through the bolts 13, the fixing effect of the connection of the bolts 13 is good, the installation and the disassembly are convenient, the driving knife 11 drives the knife holder 12 to rotate together, and the knife holder 12 further drives the driving knife 11 to rotate for cutting operation.

Of course, the diameter of the cutter holder 12 is smaller than the diameter of the active cutter 11, so that the cutter holder 12 does not affect the cutting of the active cutter 11.

In addition, the driven roller 2 and the driving roller 1 rotate in opposite directions, so that the driving knife 11 can cut conveniently, one side of the driven roller 2 is provided with a subsidiary roller 24, the subsidiary roller 24 is arranged close to the gasket 21, and a small gap is reserved between the subsidiary roller 24 and the driven roller 2, so that no bulge exists on the surface of the paperboard or the bulge is flattened through the subsidiary roller 24, the cigarette paperboard can be cut smoothly without wrinkles, and the quality of the paperboard is guaranteed.

In this embodiment, be provided with briquetting 14 between the adjacent initiative sword 11, briquetting 14 sets up on the initiative roller 1, briquetting 14 pushes down on cigarette cardboard, briquetting 14 bottom appearance with driven voller 2 looks adaptation can guarantee that the cardboard can not be pressed into concave form down when briquetting 14 pushes down for the cardboard is smoother, just briquetting 14 can avoid the cigarette cardboard to appear protruding or flatten protruding, avoids appearing because of the protruding big or small-size difference of the cardboard that leads to the cardboard of cutting out and the condition that the cigarette case is installed in place, and then leads to the quality of cigarette case not good.

The working process of the embodiment is as follows: the power supply provides power to drive the driving roller 1 to rotate, the driving roller 1 drives the driven roller 2 to rotate, meanwhile, the driving roller 1 drives the driving knife 11 to rotate together, the paper board firstly passes through the auxiliary roller 24 and then moves onto the driven roller 2 to move right below the driving roller 1, and then the driving knife 11 cuts the paper board.

The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the utility model.
