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] like figure 1 As shown, a ratchet 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. The cutter 4 is driven to move up and down by a ratchet 6 and a ratchet lever 7. The cutter 4 is vertically It is arranged at one end of the ratchet lever 7, and the other end of the ratchet lever 7 is matched with the ratchet 6. The middle part of the ratchet lever 7 is provided with a po...

Abstract

The invention discloses a ratchet wheel paper cutting device, which comprises two paper feeding rollers which are mutually cooperated, and two paper discharging rollers which are mutually cooperated, wherein a paper cutting mechanism is arranged between the paper feeding rollers and the paper discharging rollers; the paper cutting mechanism comprises a cutter and a rubber roller just below the cutter; the cutter vertically moves by being driven by a ratchet wheel and a pawl rod; the cutter is vertically arranged on one end of the pawl rod; the other end of the pawl rod is cooperated with the ratchet wheel; the middle of the pawl rod is provided with a positioning structure; the ratchet wheel is driven by a motor. Compared with the prior art, the ratchet wheel paper cutting device has the beneficial effects of precise paper cutting position, small noise and high working efficiency.

Description

technical field [0001] The invention relates to a ratchet 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. ...
