A kind of subpackage cutter sweep
The utility model relates to packaging facilities, more particularly, relates to a kind of with packaging bag string cutting device separately.
The mode of existing cutting packaging bag string mostly is at the two ends of packaging bag and is provided with the mouth that cuts that can supply cutting, utilize cutter that subpackage is cut in packaging bag in transport process; Or utilize the velocity contrast of delivery wheel and output wheel that packaging bag is torn apart subpackage.No matter above-mentioned the sort of mode is all destroyed the structure of packaging bag easily, causes breakage, and packing material is overflowed.
The purpose of this utility model can be cut difform packaging bag string in providing a kind of, and is not easy to destroy packaging bag, and can totally cut off bonded assembly Subcontracting device between packaging bag and the packaging bag up hill and dale.
The utility model is achieved by the following technical solution: construct a kind of subpackage cutter sweep, the packaging bag delivery wheel and the packaging bag output wheel that mainly comprise paired setting, it is characterized in that, two pairs of wheels are respectively by two electric machine control, an electric machine control is carried the crop rotation continuous rotation, another electric machine control output crop rotation is intermittently rotated, and is provided with between two pairs of wheels and can discerns the photoelectric switch that identifies in the packaging bag, is respectively arranged with cutter sweep on two output wheels.
Subpackage cutter sweep of the present utility model, its feature are that also described delivery wheel is two friction wheels that rotate in the same way.
Subpackage cutter sweep of the present utility model, its feature are that also the cutter sweep on the described output wheel is that cutter blades is installed respectively on the outer circumferential edges of two wheels, and one of output wheel is rotating, and another is a stationary wheel.
Subpackage cutter sweep of the present utility model, its feature is that also described output wheel is an eccentric wheel, cutter sweep on the output wheel is, the part of the outer circumferential edges of a wheel is set to the profile of tooth edge of a knife, and the outer circumferential edges of another wheel is set to have a spring leaf.
Subpackage cutter sweep of the present utility model, its feature are that also described photoelectric switch can be reflective, also can be correlations.
Adopt subpackage cutter sweep of the present utility model, can cut different sizes, difform packaging bag easily, and after cutting, can keep the integraty of packaging bag.
The utility model is described in further detail below in conjunction with drawings and Examples.
Accompanying drawing 1 is the front view of a kind of embodiment of the utility model.
Accompanying drawing 2 is the utility model birds-eye view.
Accompanying drawing 3 is the block diagram of stationary wheel for output wheel.
Accompanying drawing 4 is the front view of another embodiment of the utility model.
Subpackage cutter sweep of the present utility model, as shown in Figure 1 and Figure 4, packaging bag delivery wheel A, the C and packaging bag output wheel B, the D that mainly comprise paired setting, two pairs of wheels are respectively by two electric machine control, motor 1 control delivery wheel A, C make continuous rotation, and motor 2 control output wheel B, D do intermittently to rotate, and are provided with photoelectric switch 3 between two pairs of wheels, on two output wheel B, D, be respectively arranged with cutter sweep, be provided with sign 6 between packaging bag 7 and the packaging bag 7 for photoelectric switch 3 identifications.
A kind of embodiment of the present utility model is seen accompanying drawing 1, and delivery wheel A, C are friction wheel, photoelectric switch 3 is reflective, and cutter blades 4,5 is installed on the outer circumferential edges of output wheel B, D, and D is a stationary wheel, between packaging bag, need not cut the hole, but be provided with sealing about 10MM.As motor 1 driving delivery wheel A, when C rotates in the same way, the packaging bag string is forwarded, when packaging bag 7 is taken between B, the D wheel by the rotation of A, C wheel, photoelectric switch 3 reads the blackspot (stamping during printing) that is printed in the packaging bag 7, controller will seal 6 edge of a knife 5 places that just deliver to stationary wheel D, at this moment, motor 2 drives the B wheel and rotates, make the cut-out edge of a knife 4 on the B wheel just in time turn over the D wheel on the cut-out edge of a knife 5 tangent, just cut off the packaging bag string from sealing 6, make it to form single packaging bag 7, finish the branch packet procedures of packaging bag string.
Another embodiment of the present utility model is, sees accompanying drawing 4, and output wheel B, D are eccentric wheel, and the part of the wheel outer circumferential edges of B wheel is set to the profile of tooth edge of a knife 8, on the outer circumferential edges of another wheel D wheel a spring leaf 9 arranged.As motor 1 driving delivery wheel A, when C rotates in the same way, the packaging bag serial connection is even constantly transferred to eccentric runner B, D, this moment, B, D wheel was also done to rotate in the same way under the driving of motor 2, when photoelectric switch was ganged up in packaging bag, at this moment, if photoelectric switch is set to correlation, the light path of photoelectric switch has been blocked in packaging bag 7, photoelectric switch begins counting, 10 is the receiving unit of photoelectric switch, after if A, C wheel accurately turns over n circle, seal 6 off-positions that just arrive eccentric wheel B, D on the packaging bag string.The sealing of packaging bag arrives the eccentric wheel B edge of a knife when cutting, B wheel and D wheel rotate by direction as shown simultaneously, the B wheel edge of a knife is with the most of cut-out of packaging bag, spring leaf 9 on the D wheel is in pressured state at this moment, along with the rotation of wheel, spring leaf 9 pressurizeds on the D wheel finish, and recover elastic force packaging bag 7 bullets are fallen, tear fracture again after promptly being equivalent to cut off, thoroughly fine disconnected packaging bag.
