Description
Technical field
The utility model relates to the disk rewinding cutting means of reel material printing machine, or rather, relates to a kind of reversible cut-off knife device of reel material printing machine.
Background technology
Rewinding cut-off knife device is the indispensable important component part of reel material printing machine material-receiving system.At present, reel material printer field adopts swing arm to cut more at home, and the position that connects material preestablishes, and cuts big arm and arrives the position that connects material by the cylinder drive, and collecting shaft is turned back to the position that connects material by the rewinding frame, and positive and negative cutting by upper and lower two cut-off knives finished respectively.Along with continuous progress in science and technology, rhythm of production is constantly accelerated, the user is to the requirement trend variation of printing machine, the requirement press speed improves constantly, stability, unfailing performance strengthen, and the operation of above-mentioned technology can not meet the demands, and just must develop a kind of high-speed press that can adapt to and stablize cutting mechanism.
Summary of the invention
The purpose of this utility model is to provide a kind of reversible cut-off knife device of reel material printing machine, this kind reversible cut-off knife device can realize cutting function in fast and stable ground, and a cutter can reversible, and the success rate that connects material height is not only saved cost but also raised the efficiency.
The purpose of this utility model is achieved through the following technical solutions: a kind of reversible cut-off knife device of reel material printing machine, comprise the support and the cutting mechanism that are fixed on the material-receiving system frame, the line slideway that leads for cutting mechanism is fixed on the support, described cutting mechanism provides power by reducing motor, realize motion by rack-and-pinion, spacing before and after the cutting mechanism by finishing near switch; The cutting mechanism front end is provided with the binder rubber roll, and the both-end cylinder is equipped with in the rear end; Self-locking cuts the air cylinder driven cut-off knife, and this cylinder front end is provided with swing arm, and cut-off knife adopts the dual-purpose cutting knife of double end; Described cutting mechanism carries out position probing by potentiometer.
In the such scheme, in order to realize the detection conversion between 3 " and 6 " rewinding tube core, describedly be provided with different positions near switch.
Compared with prior art, the utlity model has following beneficial effect:
1, a cutter can reversible, has saved cost, has improved operating efficiency;
2, under high speed, cut stable, operate steadily, the success rate that connects material reaches 100%;
3, dependable performance, practicality.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the vertical view of Fig. 1.
Among the figure: 1. guide roller, 2. reducing motor, 3. self-locking cuts cylinder, 4. cut-off knife position when cutting (on cut-off knife position), 5. binder rubber roll, 6. cut-off knife position (cut-off knife position when cutting down), 7. cut support, 8. support, 9. both-end cylinder, 10. line slideway, 11. gears, 12. tooth bars, 13. near switch, 14. cut-off knives, 15. system frame, 16. swing arm, 17. potentiometers.
The specific embodiment
Below in conjunction with drawings and the specific embodiments the utility model is done detailed explanation.
By Fig. 1, guide roller 1 (two) is the material guiding, the reducing motor 2 that has brake provides power for cutting mechanism, the cutting mechanism front end is equipped with binder rubber roll 5, cut-off knife 14 cuts cylinder 3 by self-locking and drives, and self-locking cuts cylinder 3 front ends and has swing arm 16, and the rectilinear motion that self-locking is cut cylinder 3 becomes swing, cut-off knife 14 adopts the dual-purpose cutting knife of double end, realizes reversible by adjusting cutting mechanism position 4,6.
By Fig. 2, support 8 (one of operating surface, one of driving face) is fixed on the disk material-receiving system frame 15, and line slideway 10 (two) be separately fixed on the support, the sliding part of line slideway 10 links to each other with cutting mechanism, and line slideway 10 moves forward and backward guiding for cutting mechanism; The reducing motor 2 that has brake provides power for cutting mechanism, realize that by gear 11, tooth bar 12 cutting mechanism seesaws, the cutting mechanism front end is equipped with binder rubber roll 5, cutting knife is driven by self-locking cylinder 3, self-locking cylinder 3 front ends have swing arm 16, and the rectilinear motion of self-locking cylinder 3 is become swing.Cutting mechanism carries out position probing with the distance between assurance binder rubber roll and material volume within the limits prescribed by potentiometer 17, realizes the function of automatic backlash rewinding, guarantees that the rolling end face is neat under high speed.3 "-6 " conversion of rewinding tube core is by different detecting near switch 13.
This programme implementation procedure is as follows: cut ready signal when sending---and cut support 7 and under reducing motor 2 drives, travel forward, arrive desired location (by detecting 3 "-6 " respectively establish a position), cut and be ready to complete near switch.When send cut signal after---both-end cylinder 9 front ends stretch out, binder rubber roll 5 compresses the material axle, self-locking cylinder 3 stretches out, to expect severing when cut-off knife 14 is in cut-off knife position 4 or cut-off knife position 6 under self-locking cylinder 3 front end swing arms 16 drive, self-locking cylinder 3 retractions, both-end cylinder 9 front ends retraction, continue rewinding, when both-end cylinder 9 rear ends retract to the inductive switch position, cut support 7 and under reducing motor 2 drives, move rearwards to setpoint distance, realize the gap rewinding, rewinding arrives when setting coil diameter, it is spacing after moving rearwards under reducing motor 2 drives to cut support 7, and the rewinding reversing frame unlocks, and finishes a circulation.
