Abstract
A paper cutting apparatus is composed of an upper disc-shaped knife and its axle, a lower tubular knife and its rotary drive axle, a wheel-shaped lower tubular knife holder made of rubber, and with two installation holes, and an elastic unit for pushing upper knife toward lower knife. The side of upper knife is perpendicularly contacted with the lower knife and driven by the lower knife to rotate.
Description
Technical field
The present invention relates to employed plant equipment in a kind of paper industry, especially a kind of paper cutter that is used for cut paper
Background technology
In the prior art, the employed paper cutter of paper industry is many to be made of last lower round knife, and last dise knife is a disc, is provided with blade along the week edge of last dise knife, lower round knife is short tubular metal, inwardly becomes the blade of the formation lower round knife of chamfering shape with end face along tube wall at the outer surface two ends.In use, last lower round knife contacts and is fitted in the dise knife side in same plane, and lower round knife rotates under the drive of actuating unit, and by with position interlock that last dise knife contacts on dise knife rotate, paper passes through between last lower round knife, realizes the cut paper operation.But this paper cutter in use for some time, when wearing and tearing acquired a certain degree, especially the influence that is subjected to of the sharp situation of the blade of lower round knife was bigger, like this when when carrying out cut paper at the blade of last lower round knife, the side cut of lower round knife cut paper paper is easily unedged, makes paper become defective work.At this moment just need unload lower round knife at grinding machine down and carry out sharpening, and whenever carry out sharpening again, the lower round knife width reduces, and this has accelerated the consumption of cutter, and at every turn to the dismounting of lower round knife also unusual inconvenience, has seriously influenced production efficiency.
Summary of the invention
The technical problem to be solved in the present invention has provided a kind of paper cutter, and its lower round knife can use for a long time and not need the frequent dismounting sharpening that carries out.
For solving the problems of the technologies described above, technical scheme of the present invention is: paper cutter, comprise discoid dise knife and the light wall pipe shape lower round knife gone up, the rotatable rotating shaft that the pivot of dise knife is set and can drives the lower round knife rotation, the described cutter side that goes up dise knife can be rotated under the drive of lower round knife with vertical the contact also of blade of lower round knife, described paper cutter comprises that also one is fixed on the colyliform tool rest of being made by elastomeric material in the rotating shaft, described lower round knife suit is fixed on tool rest, and the wheel of described colyliform tool rest is provided with the installing hole that is communicated with the tool rest both sides along the place; Described paper cutter also comprises and can push the elastic device of lower round knife to going up dise knife.
As a kind of optimal way, described pivot is provided with two tingles, and the described dise knife of going up is by being arranged on the pivot that two tingles rotate.
As another kind of optimal way, described elastic device is for being arranged on the pivot upper spring.
As another kind of optimal way, the described discoid discoid dise knife of going up that dise knife is thickness 0.4~1.2mm of going up, the lower round knife of described light wall pipe shape is that pipe thickness is the light wall pipe shape lower round knife of 0.4~1.2mm.
Adopt the said structure paper cutter, owing to adopted the lower round knife of sheet steel pipe shape, the thickness of the edge of a knife is as the thickness of the lower round knife of sheet steel pipe shape in the time of so just can adopting the dise knife that is equivalent to use in the prior art to be fit to cut paper, make not rust of lower round knife, so need not carry out sharpening to it with wearing and tearing.And the last dise knife of this paper cutter just carries out contact wear at cutter hub up and down dise knife, does not have the wearing and tearing of sword, so do not need it is carried out sharpening, has made things convenient for production.And adopt the colyliform tool rest of making by elastomeric material and be provided with the installation that the installing hole that is communicated with the tool rest both sides can make things convenient for lower round knife; With the steadiness of last dise knife by two tingle rotational fixation dise knife on can strengthening on the pivot; And promote spring and dise knife is remained with the stable of lower round knife contact being provided with on the pivot.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present invention is further described:
Fig. 1 is the structural representation of paper cutter of the present invention;
Fig. 2 is the lower round knife of paper cutter of the present invention and the mounting structure schematic diagram of tool rest.
The specific embodiment
With reference to Fig. 1, a kind of paper cutter of the present invention is: rotating shaft 8 that is provided with on body and pivot 2, pivot 2 rotate be provided with discoid on dise knife 1, and in order to strengthen the steadiness of going up dise knife 1, can establish two tingles 3 at pivot 2, last dise knife 1 is by being arranged on the pivot 2 that two tingles 3 rotate.In rotating shaft 8, be provided with light wall pipe shape lower round knife 6 by the colyliform tool rest 5 that is fixed with, the cutter side of last dise knife 1 can be rotated under the drive of lower round knife 6 with vertical the contact also of the blade of lower round knife 6, thereby rotating shaft 8 can drive colyliform tool rest 5 and drive lower round knife 6 rotations, this colyliform tool rest 5 can be made by elastomeric material, and lower round knife 6 suits are fixed on the tool rest 5.And the convenience in order to install, as shown in Figure 2, can be provided with the installing hole 7 that is communicated with tool rest 5 both sides at the wheel of colyliform tool rest 5 along the place, and make the internal diameter size of lower round knife 6 be slightly less than the external diameter of colyliform tool rest 5, when mounted, adopt in the installing hole 7 on the kelly insertion lower round knife 6 colyliform tool rest 5 is inwardly pushed, thereby colyliform tool rest 5 radial dimension that deforms is diminished, lower round knife 6 is put, unclamp kelly, colyliform tool rest 5 recovers, and lower round knife 6 can be fixed on the colyliform tool rest 5; Contact for dise knife is remained with the stable of lower round knife, also can be provided with one and will go up the elastic device 4 that dise knife 1 is pushed lower round knife 6 to, and for simply, elastic device 4 will be gone up the direction that dise knife 1 is pushed lower round knife 6 to for being located at pivot 2 upper springs by spring.
Paper cutter of the present invention is simple in structure, and it is easy to use, in when, in lower round knife 6 uses wearing and tearing taking place, all the time will go up dise knife 1 and promote to be in contact with it by being installed in spring on the pivot, when wear phenomenon becomes big, because what lower round knife 6 adopted is the light wall pipe shape, its tube wall can be arranged to roughly and being of uniform thickness of the blade of last dise knife 1, as be 0.4~1.2mm, at this moment, only need colyliform tool rest 5 inwardly tighten, lower round knife 6 dise knife 1 direction that makes progress is moved certain size and gets final product with kelly, equally, the thickness of last dise knife 1 also can be arranged to identical thickness, when when wearing and tearing take place last dise knife 1, only needs to go up dise knife 1 and moves down and get final product, promptly convenient, practical again.
