Detailed description of the invention
Circular fly cutter in this utility model be refer in particular to be arranged on Polywoven Bag (film) cold cut cutting bag machine automatically can the circular industrial blade of rotation, the mechanism that fixing circular industrial blade realizes rotation cutting is referred to as fly knife device.Fly knife device in this utility model has four kinds, and optional any of which is implemented.
Embodiment one
See figures.1.and.2, this utility model it include support 1;The top of described support 1 is provided with the drivewheel 6 and follower 3 connected by synchronous belt 4 horizontal conveyor;Described drivewheel 6 is in transmission connection with the servomotor 2 of support 1 side;Described support 1 is provided with between drivewheel 6 and follower 3 and corresponding with its level line slideway 8;Slide on described line slideway 8 and be provided with the top slide block 5 that be connected fixing with synchronous belt 4;Described slide block 5 is connected by connecting plate 7 is fixing with the bearing block 14 outside it;It is rotationally connected a rubber tire 15 on described bearing block 14, and the outside of rubber tire 15 is fastenedly connected with circular fly cutter 9 by bolt;The bottom of described rubber tire 15 is provided with up and down the most corresponding with it and fixes, with support 1, the rubber tire guide rail 10 being connected;Described support 1 is provided with the horizontal cutter groove 11 corresponding with circular fly cutter 9.
Embodiment two
Can be rotationally connected with gear 17 with reference to the bearing block 14 in Fig. 3 this utility model, gear 17 engages each other with the tooth bar 16 being fixedly connected on support 1 and is in transmission connection, and circular fly cutter 9 is fixing with gear 17 to be connected;Therefore, when gear 17 moves horizontally on tooth bar 16, circular fly cutter 9 can be driven to move horizontally and circular fly cutter 9 also moves in a circle simultaneously;Owing to the diameter of circular fly cutter 9 is more than the diameter of gear 17, therefore, the linear velocity of the linear velocity gear to be far longer than 17 of circular fly cutter 9, the resistance being run into fly cutter 9 circular in cutting process is negligible, thus without installing bag compression framework additional, structure simplifies.
Embodiment three
19 can be rotationally connected with Tong Bu wheel with reference to the bearing block 14 in Fig. 4 this utility model, and synchronize wheel 19 and engage each other with Timing Belt 18 and be in transmission connection;Timing Belt 18 and synchronous belt 4 the most synchronized mutual transmission;Synchronizing wheel 19 to move horizontally under being in transmission connection of Timing Belt 18, circular fly cutter 9 is fixing with Tong Bu wheel 19 again to be connected, and diameter is more than synchronizing wheel 19;Therefore, the linear velocity of circular fly cutter 9 to be far longer than the linear velocity synchronizing wheel 19, and the resistance being run into fly cutter 9 circular in cutting process is negligible.
Embodiment four
Fixing with connecting rod 20 can be connected with reference to the connecting plate 7 in Fig. 5 this utility model, and the bottom of connecting rod 20 is provided with motor 21;The rotating shaft 22 of motor 21 is fixing with circular fly cutter 9 to be connected;Motor 21 is connected by connecting rod 20 is fixing with connecting plate 7, can move along with slide block 5 level of synchronization, and the rotating shaft 22 of motor 21 also moves in a circle, thus drive the circular fly cutter 9 being secured to connect to rotate, and the linear velocity of the linear velocity rotating shaft to be far longer than 22 of circle fly cutter 9, the resistance being run into fly cutter 9 circular in cutting process is negligible.
The two sides of the circular fly cutter 9 in this utility model are respectively equipped with clip plate 13 and outer plate 12, primarily serve and circular fly cutter 9 is added the effect fastened, and prevent circular fly cutter influence of crust deformation cutting effect;The diameter of circular fly cutter 9 is all higher than rubber tire 15, gear 17, synchronizes wheel 19 and the diameter of rotating shaft 22, and circular fly cutter rotates the linear velocity produced and is greatly improved, hence it is evident that reduce the Cutting Drag run in cutting process.
Operation principle: servomotor 2 can rotating drive drivewheel 6 to rotate, drivewheel 6 drives follower 3 to rotate by synchronous belt 4, is connected owing to slide block 5 is fixed with synchronous belt 4, and therefore slide block 5 can move horizontally on line slideway 8;Slide block 5 is connected further through connecting plate 7 is fixing with bearing block 14, and the rubber tire 15 that bearing block 14 is rotationally connected can be synchronized with the movement with slide block 5, and rubber tire 15 is horizontal movement the rotation that rubs on rubber tire guide rail 10;The outside of rubber tire 15 is fixing with circular fly cutter 9 to be connected, and therefore circular fly cutter 9 can move in a circle while doing horizontal reciprocating movement.Circular fly cutter 9 is industrial blade, and diameter is more than rubber tire 15 external diameter, thus the linear velocity i.e. rotary speed of circle fly cutter cutting, all the time several times higher than the linear velocity of the rubber tire of horizontal direction simultaneous displacement, so, plastic sheeting or woven bag are when cut, and the resistance of cutting is negligible for the rotary speed of circular fly cutter completely, and therefore material to be cut plastic sheeting or woven bag will not be subjected to displacement.
The beneficial effects of the utility model are: one, negligible to the resistance of circular fly cutter during cutting, without presser feet bag pressing during work, save bag compression framework;Two, Cutting Drag is small, reduces motor load and inertia, and motor itself can improve speed, thus improves cutting efficiency;Three, without bag compression framework, save the time of bag pressing action, and then improve complete machine work efficiency and capacity and output;Four, using circular fly cutter circumgyration incision, for the most all kinds of fixing, semifixed cutters (moving knife and stationary knife), in the unit interval, blade shortened with the time of contact of material to be cut, and the degree of wear of cutter is greatly reduced;Five, circular fly cutter does not contact as unsettled cutting with horizontal cutter groove 11, hard to soft cutting edge can autogenous grinding, be greatly prolonged the service life of cutter;Six, circular fly cutter belongs to the easy-consumed goods of low value, and installation is changed simple and easy, used manpower and material resources sparingly, and reduces cost.
Finally, in addition it is also necessary to it is noted that listed above is only several specific embodiments of the present utility model.Obviously, this utility model is not limited to above example, it is also possible to have many deformation.All deformation that those of ordinary skill in the art can directly derive from this utility model disclosure or associate, are all considered as protection domain of the present utility model.
