Problems solved by technology

[0011] However, when cutting paper, the cutting knife and the lower knife need to be fully matched together to complete the function of paper cutting. There are slight deviations, such as: the cutting knife is not rotated in place, the lower knife is not adjusted in place, and the edge of the cutting knife and the lower knife are not meshed. And so on will lead to paper cutting failure

Embodiment Construction

[0029] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0030] Such as figure 1 As shown, a hydraulic paper cutting device includes two mutually matched paper feed rollers 1 and two mutually matched paper output rollers 2, and a paper cutting mechanism 3 is arranged between the paper feed roller 1 and the paper output roller 2, The paper cutting mechanism 3 includes a cutter 4 and a rubber roller 5 arranged directly below the cutter 4. The cutter 4 is arranged on the free end of the piston rod 7 of the hydraulic cylinder 6. The cutter 4 Under the driving action of hydraulic cylinder 6, it moves up and down.

[0031] The rotation direction of the rubber roller 5 is consistent with the paper output direction.

Abstract

The invention discloses a hydraulic paper cutting device comprising two paper feed rollers matched with each other and two paper delivery rollers matched with each other. A paper cutting mechanism is arranged between the paper feeding rollers and the paper delivery rollers and comprises a cutter and a rubber roller arranged under the cutter, the cutter is arranged at the free end of a piston rod of a hydraulic cylinder, and the cutter is driven by the hydraulic cylinder to move up and down. Compared with the prior art, the hydraulic paper cutting device has the advantages of accurate paper cutting position, small noise and high working efficiency.

Description

technical field [0001] The invention relates to a hydraulic paper cutting device. Background technique [0002] Paper cutters are used to cut paper rolls into pieces. There are many kinds of paper cutters, such as the gate knife for cutting up and down, the swing knife for intermittent cutting, etc. Although the cutting quality of the paper edge is relatively poor Good, but the paper must be stopped, and the paper can continue to be fed after cutting. The paper feeding speed cannot be fast, and the production efficiency is very low; although the swinging knife can feed the paper continuously, the mechanical impact at the moment of cutting is relatively large, which may easily cause damage to the mechanical equipment. Damage and noise pollution, at the same time, the speed of paper feeding should not be too fast, and the length of paper sheets should not be too short, otherwise there is no time to stop the knife in the middle, resulting in inaccurate length of paper cutting. ...
