Abstract
The utility model relates to a paper cutting device for a printing machine. The paper cutting device comprises a paper cutter, a connecting base, a cutter shaft, a driving member and a cutter box, wherein the paper cutter is arranged on the connecting base; the connecting base is connected with the cutter shaft and can rotate along with the cutter shaft together with the paper cutter under the action of the driving member; when at a non-paper cutting state, the paper cutter is pushed into the cutter box to be hidden under the action of the driving member, and the cutter box is positioned on the side of a paper tape on the printing machine. The paper cutting device has the advantages of simple and compact structure, simple and convenient operation, good safety, high reliability and the like.
Description
Technical field
The utility model is mainly concerned with printing mechanism field, refers in particular to a kind of disconnected paper apparatus for rotary press that is applicable to folding machine.
Background technology
Business rotary press two maximum features compared with common sheet-fed press are exactly: the first, and print speed printing speed is fast, can reach the soonest 18m/s; The second, the raw material using in printing process is by the paper tape to front haulage continuously, finally by folding machine, breaks to go out to paste.From above 2: printing machine is the in the situation that of high speed printing, the phenomenons such as subsides are not smooth if folding machine rear end goes out, paperboard, the consequence causing is beyond imagination, only need several seconds time at a large amount of paper of folding apparatus inner accumulated, when this paper jam phenomenon is serious, can cause destructive destruction to corresponding equipment.As shown in Figure 1, while normally printing, paper tape 10 is drawn by upper draw rollers group 11, lower draw rollers group 12, in a direction indicated by the arrow from top to bottom rapidly through disconnected paper apparatus.Existing disconnected paper cutter mechanism comprises tool rest 1, fixing edge bearing 2, disconnected paper cutter 3, Connection Block 4, cutter shaft 5 and cylinder 6, fixing edge bearing 2 coordinates with disconnected paper cutter 3 realizes disconnected paper, disconnected paper cutter 3 is installed on Connection Block 4, Connection Block 4 is connected with cutter shaft 5 and can rotates with cutter shaft 5, and the telescopic end of cylinder 6 is connected with Connection Block 4 and can drives Connection Block 4, cutter shaft 5 and disconnected paper cutter 3 to rotate.In above-mentioned this structure, employing be the mode that rigidity is cut off, be easy to cause personal injury, the paper simultaneously cutting off is not because in time guide away problems such as being easy to cause secondary winding.
Utility model content
The technical problems to be solved in the utility model is just: the technical problem existing for prior art, the utility model provides a kind of printing machine simple and compact for structure, easy and simple to handle, that security is good, reliability is high disconnected paper apparatus.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
Disconnected paper apparatus for a kind of printing machine, comprises disconnected paper cutter, Connection Block, cutter shaft, actuator and cutter box, and described disconnected paper cutter is installed on Connection Block, and described Connection Block is connected with cutter shaft and can under the effect of actuator, with disconnected paper cutter, with cutter shaft, rotates; In being pushed into cutter box under the effect of disconnected paper cutter at actuator described in when non-disconnected paper state, hide, described cutter box is positioned at a side of printing machine tape loading.
As further improvement of the utility model:
A side of cutting off paper tape at described disconnected paper cutter is provided with slips cardboard, described in slip cardboard and cut off after operation disconnected paper cutter and form one and lead paper plane with completing.
Described cutter box is a semiclosed box being made by panel beating bending.
Compared with prior art, the utility model has the advantage of: the utility model is simple and compact for structure, easy and simple to handle, can just initiatively cut off paper tape in the moment of paper jam, stop follow-up paper tape to enter folding apparatus, thereby play the object of protection folding machine.When normally printing, cylinder, in elongation state, in cutter box, avoids accidentally injuring operator by hidden cutter.When breaking paper operation, cylinder shrinks, and by cutter pull-out, cutter contacts with paper tape, is cut off, and whole cutting-off process does not have rigidity edge bearing, so there will not be the rigid phenomenon of chopping off, reduces extent of injury.The utility model is after cutting off paper, and cylinder keeps duty, and knife face and the cardboard that slips form one and lead paper plane, and paper is discharged to folding apparatus, avoids secondary to be wound around.Compare traditional disconnected paper apparatus, design of the present utility model, manufacture, assembling and adjustment are more simple and convenient.

Fig. 2 is the structural representation of the utility model in concrete application example.
Marginal data:
1, tool rest; 2, fixing edge bearing; 3, disconnected paper cutter; 4, Connection Block; 5, cutter shaft; 6, cylinder; 7, slip cardboard; 8, cutter groove; 9, cutter box; 10, paper tape; 11, upper draw rollers group; 12, lower draw rollers group.
The specific embodiment
Below with reference to Figure of description and specific embodiment, the utility model is described in further details.
As shown in Figure 2, disconnected paper apparatus for printing machine of the present utility model, comprise disconnected paper cutter 3, Connection Block 4, cutter shaft 5, actuator (as cylinder 6) and cutter box 9, disconnected paper cutter 3 is installed on Connection Block 4, Connection Block 4 is connected with cutter shaft 5 and can under the effect of actuator, with cutter shaft 5, rotates, thereby rotates with disconnected paper cutter 3.During non-disconnected paper state, disconnected paper cutter 3 is pushed in cutter box 9 under the effect of actuator, and cutter box 9 is positioned at a side of paper tape 10.
In specific embodiment, this cutter box 9 can be a semiclosed box, by panel beating bending, is made, and conventionally paints yellow warning coloration, is provided with cutter groove 8 in cutter box 9.
As preferred embodiment, the side that the utility model cuts off paper tape 10 at disconnected paper cutter 3 is provided with slips cardboard 7, and this slips cardboard 7 and cuts off after operation disconnected paper cutter 3 and form one and lead paper plane with completing.
During normal printing, paper tape 10 is drawn by upper draw rollers group 11, lower draw rollers group 12, in a direction indicated by the arrow from top to bottom rapidly through disconnected paper apparatus.Now, cylinder 6, in stretching out state, pushes the disconnected paper cutter 3 being fixed on cutter shaft 5 in cutter box 9, and disconnected paper cutter 3 is hidden in cutter box 9 in the thrust of cylinder 6, plays safeguard protection effect.
When cylinder 6 is received disconnected paper signal, contraction bands movable arbor 5 rotates rapidly, and the paper cutter 3 that will break pulls out from cutter box 9.Because paper tape 10 itself has certain tension force, now again in fast state, so contacting the moment of paper tape 10, the paper cutter 3 that breaks just can be cut off, without there being edge bearing to coordinate; After cut-out, cylinder 6 state that remains retracted, this moment disconnected paper cutter 3 with slip cardboard 7 and form one and lead paper plane, this plane guide away follow-up paper tape 10, avoids being wrapped in lower draw rollers group 12 or other equipment, causes secondary winding.
As can be seen here, in whole course of action, disconnected paper knife system of the present utility model, when cutting off paper tape 10, can also be discharged folding apparatus by follow-up paper tape 10, thereby plays the object of protection folding apparatus.
Below be only preferred embodiment of the present utility model, protection domain of the present utility model is also not only confined to above-described embodiment, and all technical schemes belonging under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, in the some improvements and modifications that do not depart under the utility model principle prerequisite, should be considered as protection domain of the present utility model.
