Compared with the prior art, the utility model has the beneficial effects of being capable of keeping constant tensions during the whole unreeling process and being hard to be damaged as the utility model is provided with the variable frequency motor and the closed ring vector control device.
Description
Technical field
The utility model relates to a kind of packing Fabricating machinery, more specifically to a kind of active unwinding device.
Background technology
In the blister-pack industry, the packing Fabricating machinery, as: equipment such as coating machine, cutting machine, aluminum-spraying machine all can have the step that unreels.For the whole process that guarantees to unreel is all enough stablized, overtension, phenomenon loose when rouleau starts take place when avoiding rolling up greatly, and traditional unwinding device all is to adopt the mechanical drive electromagnetic power brake.
As Chinese patent literature CN2221582 " Winder's Tension Control device ", just adopted electromagnetic power brake to control tension force.But its shortcoming is: the crankshaft drive of machinery is very serious to the wearing and tearing of mechanical part, and the inner friction heating of electromagnetic power brake seriously makes tension fluctuation bigger, has influenced the product design of finished product.In general, the mean life that is used for the mechanical part of crankshaft drive part is about 1 year basically.
In addition, electromagnetic power brake often heating excessively burns out, and causes stopping production, often needs when therefore using to safeguard.It safeguards very trouble, not only waste of manpower, and also maintenance cost is very high, has had a strong impact on normal production.Especially aluminize, cut, equipment such as rewinding are not allow stop off after the start basically, need parking can cause very big waste as something unexpected happened.
Summary of the invention
The purpose of this utility model is that prior art is improved, and a kind of active unwinding device is provided, and can all keep constant tension force in the whole process that unreels, and is not easy to damage, and the technical scheme of employing is as follows:
Active unwinding device of the present utility model, comprising that two supports, two ends are rotating respectively is fixed on two spools between the support, spool is provided with ring gear, it is characterized in that: a described support is provided with variable-frequency motor and closed-loop vector control setup, the output shaft of variable-frequency motor is provided with a driving gear, driving gear and ring gear engagement.
Described closed-loop vector control setup comprises converter plant, coder, coil diameter sensor and calculation control module, the signal output part of the signal output part of coder and coil diameter sensor is connected two signal input parts of calculation control module respectively, the signal output part of calculation control module connects converter plant, the signal output part of converter plant connects variable-frequency motor, and the rotation shaft coupling of coder is connected with variable-frequency motor; Coder sends counting pulse signal to calculation control module, coder detects and calibrates the rotating speed of variable-frequency motor, the coil diameter sensor sends the coil diameter signal to calculation control module, calculation control module is carried out computing to the signal that sends, and export suitable dtc signal and speed signal and give converter plant, converter plant drives variable-frequency motor and rotates.Calculation control module is constantly calculated in real time to coil diameter, and changes the suitable dtc signal of output according to coil diameter and drive variable-frequency motor to converter plant, and the level and smooth performance that therefore can guarantee to unreel motor output torque is good.Because the rotor inertia of unwinding device is very big, coil diameter if operating personal quickens, slows down, stops, is easy to when activating cause again quick-fried loosing and loose phenomenon, will directly influence the quality that unreels of film from large to small the time.Can cause to draw high such as radium-shine film to make version, more make the loose sideslip of rolling apart from changing etc.After having adopted the closed-loop vector control setup,, also can guarantee the stable and constant tension force that unreels even run into similar above-mentioned situation.And,, therefore be not easy to damage owing to there is not the mechanical wear of similar electromagnetic power brake.
Described coil diameter sensor is a ultrasonic transduter.
Described coil diameter sensor also can adopt near switch.
The utility model beneficial effect against existing technologies is owing to be provided with variable-frequency motor and closed-loop vector control setup, therefore can all keep constant tension force in the whole process that unreels, and be not easy to damage.
