Drive device is provided with above shape projection；Drive device includes being connected with two shoes being set up in parallel on belt pulley, belt pulley
Band；It is provided between two crawler belts on space, space and is connected with multiple fixing screws, arc is respectively connected with each fixing screws
Shape projection.
In a kind of foregoing printing machine cutting means easy to adjust, the position of the arc lower projection is located at upper arc
On the mobile route of projection, and size of the size less than upper arc bump of arc lower projection, arc lower projection can be more preferable
Moved down by the effect of upper arc bump.
In a kind of foregoing printing machine cutting means easy to adjust, in the middle part of the side of the belt pulley correspondence space
Annular groove is provided with position.
In a kind of foregoing printing machine cutting means easy to adjust, on the material conveying platform at the position of correspondence cutting knife
Provided with groove, the auxiliary cutting knife of the edge of a knife upward is provided with groove；Aid in the cut angle phase of the cut angle and cutting knife of cutting knife
Together, the bottom of auxiliary cutting knife is provided with second spring.
Compared with prior art, present invention improves over existing cutting means structure, by setting upper arc bump, lower arc
Shape projection, crawler belt and belt pulley are cut to drive cutting knife to move down, and by the first spring that the cutting knife moved down is quick
Retract, prevent cutting knife from blocking printed matter；The mobile of cutting knife can be oriented to by guide rail bracket, so that it is guaranteed that cutting knife can be erected
Directly move back and forth, but also spacing, arc bump driving arc lower in counteracting can be carried out to cutting knife from the left and right ends of cutting knife
The horizontal applied force produced during projection, prevents cutting knife from receiving off normal after the impulsive force of arc bump, it is to avoid the damage of cylinder class
Consumption, it is ensured that cut stable accuracy；During regulation, by adjusting the distance between two neighboring upper arc bump or adjusting belt pulley
Rotating speed, you can the adjacent printed matter for declining the time interval cut twice, cutting out different length of regulation cutting knife, or even can also
The alternating for a variety of different length printed matters is cut simultaneously, convenient regulation, and improves regulation efficiency.In addition, the present invention is also
There is provided annular groove, can use same group of belt pulley while transmitting two crawler belts for leaving gap each other, and can be square
Just the fixing screws of upper arc bump are fixed as crawler belt is moved together；By setting groove, auxiliary cutting knife and second spring,
Breaking out cut can be carried out below printed matter, second spring can also enter row buffering to cutting knife after the completion of cutting, prevent from cutting
Knife edge of a knife impact injury, improves and cuts effect, and extend service life.Therefore, the present invention can not only ensure to cut essence
Degree is stable, additionally it is possible to convenient regulation, improves regulation efficiency, has the advantages that to cut that effect is good and service life is long.

Embodiment
The present invention is further illustrated with reference to the accompanying drawings and examples, but be not intended as to the present invention limit according to
According to.
Embodiment.A kind of printing machine cutting means easy to adjust, are constituted as shown in Fig. 1 to 5, including material conveying platform 1,
The top of material conveying platform 1 sets organic frame 2；The lower section of frame 2 is connected with cutting knife 4 by the first spring 3, and the two ends of cutting knife 4 are all connected with
There is guide rail bracket 5, the two ends of guide rail bracket 5 are connected with material conveying platform 1 and frame 2 respectively；The side of the cutting knife 4 is provided with arc lower
Projection 6, the top of arc lower projection 6 is provided with drive device；Drive device includes being connected with two on belt pulley 7, belt pulley 7
The crawler belt 8 being set up in parallel；It is provided between two crawler belts 8 on space 9, space 9 and is connected with multiple fixing screws 10, it is each fixed
Arc bump 11 is respectively connected with screw 10.
The position of the arc lower projection 6 is located on the mobile route of upper arc bump 11, and the size of arc lower projection 6
Less than the size of upper arc bump 11, arc lower projection 6 can be moved down preferably by the effect of upper arc bump 11；Institute
State and be provided with annular groove 12 at the position in correspondence space 9 in the middle part of the side of belt pulley 7；The position of correspondence cutting knife 4 on the material conveying platform 1
Put to locate to be provided with groove 13, groove 13 and be provided with the auxiliary cutting knife 14 of the edge of a knife upward；Aid in the cut angle and cutting knife 4 of cutting knife 14
Cut angle it is identical, auxiliary cutting knife 14 bottom be provided with second spring 15.
Operation principle：In use, cutting knife 4 is hanging under the pulling force effect of the first spring 3；Material conveying platform 1 send printed matter
To the lower section of cutting knife 4, belt pulley 7 is driven using motor, and belt pulley 7 drives two crawler belts 8 to move simultaneously after rotating, mobile form with
Toothed belt transmission is identical；Upper arc bump 11 is connected behind gap of the fixing screws 10 through two crawler belts 8, so that upper arc
Shape projection 11 is fixed on crawler belt 8 and as crawler belt 8 is moved；Upper arc bump 11 is moved when being contacted as arc lower projection 6, meeting
Thrust in one thrust and a horizontal direction straight down is produced to arc lower projection 6；Arc lower projection 6 vertically to
Under thrust under drive cutting knife 4 moved down along guide rail bracket 5, cut；Power in horizontal direction is acted on to cutting knife 4
