Problems solved by technology

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

Embodiment Construction

[0030] 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.

[0031] Such as figure 1 As shown, a paper cutting device includes two paper feed rollers 1 that cooperate with each other and two paper output rollers 2 that cooperate with each other. A paper cutting mechanism 3 is provided between the paper feed roller 1 and the paper output roller 2. The paper cutting mechanism 3 includes an upper knife 4 and a rubber roller 5 arranged directly below the upper knife 4, the upper knife 4 is arranged at the lower end of a vertically arranged rack 6, and the rack 6 is positioned at the bottom of the gear 7 to move up and down, and the gear 7 is set on the output shaft of the motor through a coupling.

Abstract

The invention discloses a paper cutting unit comprising two feed rollers and two discharge rollers. The feed rollers fit each other; the discharge rollers fit each other. A cutting device is disposed between the feed rollers and the discharge rollers and comprises an upper blade and a rubber roller disposed right under the upper blade. The upper blade is disposed at the lower end of a rack vertically arranged. The rack is driven by a gear to move up and down. The gear is disposed on an output shaft of a motor through a coupling. Compared with the prior art, the paper cutting unit has the advantages that cutting position of paper is accurate, noise is low, and operating efficiency is high.

Description

technical field [0001] The invention relates to a 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.
