Abstract
The utility model belongs to the technical field of packaging machines, and particularly relates to a four-cutter roll cutting device which comprises a barrel body. Four cutter sliding grooves are evenly formed in the barrel body, cutters are arranged in the cutter sliding grooves respectively, the two ends of each cutter are connected with screw rods respectively in the length direction, each screw rod is connected to the inside of an inner threaded hole of a turbine in a threaded mode, and the turbine is matched with a worm rod arranged in the axial direction of the barrel body. Four screw rods of two cutters in the same straight line of the radial direction of the barrel body are parallel and staggered. A screw rod accommodating cavity is formed in the portion, corresponding to the connection end of each screw rod and the turbine, of each cutter. The four-cutter roll cutting device is simple in structure and reasonable in design, when the roll cutting device is used for processing paper, paper cutting speed can be effectively increased, paper with regulated lengths can be cut according to needs, and the application range of the roll cutting device is greatly expanded.
Description
Technical field
The utility model belongs to packing machinery technology, specifically a kind of four blade rolling cutting device.
Background technology
In packaging industry, can energy-efficient be eternal topic all the time, improve cut paper speed, will play decisive role to overall performance; In addition, cut paper length range is also extremely important.
In prior art, the cutting knife that exceedes 200 cuttves per minute, under the requirement of random length, can't realize the paper that cuts out as requested the length that conforms with the regulations preferably, i.e. 200 cuttves/minute above cut paper speed cannot realize.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of simple in structure, ingenious, rational four blade rolling cutting device is provided, and this rolling cutting device not only can improve cut paper speed, can also cut out as requested the paper conforming with the regulations.
The technical scheme providing according to the utility model: a kind of four blade rolling cutting device, it is characterized in that: comprise cylindrical shell, uniformly on described cylindrical shell offer four cutting knife chutes, in each described cutting knife chute, be provided with a cutting knife, described cutting knife along its length two ends connects respectively a rhizoid bar, every described screw mandrel is all threadedly connected in the internal thread hole of a turbine, described turbine with match along the axial arranged worm screw of cylindrical shell; Along four rhizoid bars on two cutting knifes on the radially same straight line of cylindrical shell be parallel to each other, interlaced arrangement; On each cutting knife, be connected corresponding section, turbine one end with screw mandrel and all offer screw mandrel container cavity.
As further improvement of the utility model, when described screw mandrel shrinks completely in screw mandrel container cavity, the cutting knife being connected with described screw mandrel shrinks in cylindrical shell.
As further improvement of the utility model, described turbine rotation is spacing to be fixed in cylindrical shell.
The utility model compared with prior art, advantage is: the utility model product structure is simple, reasonable in design, use the utility model product processing paper, not only can effectively improve cut paper speed, can also cut out as requested the paper of the length that conforms with the regulations, greatly widen the scope of application of this product.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is cross-sectional view of the present utility model.
Detailed description of the invention
Below in conjunction with concrete drawings and Examples, the utility model is described in further detail.
As shown in Figure 1 and Figure 2, comprise cylindrical shell 1, cutting knife 2, screw mandrel 3, worm screw 4, turbine 5, screw mandrel container cavity 6 etc.
As shown in Figure 1 and Figure 2, a kind of four blade rolling cutting device of the utility model, comprise cylindrical shell 1, uniformly on described cylindrical shell 1 offer four cutting knife chutes, in each described cutting knife chute, be provided with a cutting knife 2, cutting knife 2 all can relatively move in each self-corresponding cutting knife chute, stretches out the length of cylindrical shell 1 according to the length adjustment cutting knife 2 of wanted cut paper; Described cutting knife 2 along its length two ends connects respectively a rhizoid bar 3, being connected between screw mandrel 3 and cutting knife 2 can connect or other can, by mode fixed with each other to screw mandrel 3 and cutting knife 2, can drive cutting knife 2 to stretch out or contractile motion to realize screw mandrel 3 by welding manner; Every described screw mandrel 3 is all threadedly connected in the internal thread hole of a turbine 5, described turbine 5 with match along the axial arranged worm screw 4 of cylindrical shell 1, and turbine 5 rotary spacings are fixed in cylindrical shell 1, be that turbine 5 is merely able to rotate in cylindrical shell 1, and can not produce the movement of position, because turbine 5 endoporus are provided with the screw thread matching with screw mandrel 3, therefore the rotation of turbine 5 is stretched out natural zone movable wire bar 3 or contractile motion; Along four rhizoid bars 3 on two cutting knifes on the radially same straight line of cylindrical shell 1 be parallel to each other, interlaced arrangement; On each cutting knife 2, be connected turbine 5 corresponding sections, one end with screw mandrel 3 and all offer screw mandrel container cavity 6, in the time that screw mandrel 3 shrinks completely in screw mandrel container cavity 6, the cutting knife 2 being connected with described screw mandrel 3 shrinks in cylindrical shell 1, this just can ensure in the time cutting minimum length paper or do not need cut paper, cutting knife can be drawn in completely or not exclusively in cylindrical shell 1.
Operation principle of the present utility model is as follows: the length of short paper that the utility model product can cut out is 1/4th of cylindrical shell 1 girth, cut out the paper of above-mentioned dimensions, only four cutting knifes 2 need be reduced to minimum bit, that is, the cutting edge of cutting knife 2 has just stretched out cylindrical shell 1.The length of the paper cutting out when needs is greater than four of cylindrical shell 1 girth/for the moment, can regulate four cutting knifes 2 to stretch out cylindrical shell 1 with equal length; In the time needing the length of cut paper to exceed four cutting knifes 2 all to stretch out maximum length, when the length of the paper that can cut out, the quantity that can stretch out the cutting knife 2 of cylindrical shell 1 by minimizing realizes the object of the corresponding expansion of cut paper length, common way is that contracting is fallen along two corresponding cutting knifes 2 of cylindrical shell 1 diametric(al), makes to only have two cutting knifes to carry out cut paper operation in paper cutter.The maximum length of the paper that the utility model product can cut out is, realization while only cutting knife being carried out to cut paper with one, that is, general wherein three shrinks in cylindrical shell 1 all or part of cutting knife, and only retain one, cutting knife is stretched out to cylindrical shell 1, and this cutting knife is all stretched out to cylindrical shell 1.
In when work, coordinate that the utility model four blade rolling cutting device is also corresponding is equipped with a lower roll, uniformly on this lower roll periphery be provided with four slide blocks, four slide blocks play the effect of edge bearing, and this slide block matches and carries out work with four blade rolling cutting device; In the course of work, corresponding idle slide block can a little less than work the edge of a knife, that is to say, idle cutting knife (slide block) needn't all be reduced to the end.
