Film take-up process: film is received after reaching from top to down, by entering tightening folder after angle tension-adjusting gear 71
Rod 72, the tightening folder closure of rod 72 drive film to advance, enter friction roller by guide roller group 74, after being flattened by nip rolls and wind.
It is in isosceles triangle between guide roller group 74 and nip rolls, is conducive to detect the tune after the tension precision convenience of film in this way
Section.By the setting to PLC, when the tension in guide roller group 74 is beyond setting numerical value, PLC will be by controlling angle tension
Low rubbing cylinder in regulating device 71 is adjusted, then by pivot angle gear and angle positioner feedback, precision is greatly increased to more preferable
Control membrane tension.
After wind operation workflow: winding cylinder moves Scroll by winding armband, moves to its Scroll and gives directions position, it
Start pressure roller cylinder afterwards and pressure roller is affected to open, restarts pivoted arm and live-roller is driven to rise in place, live-roller is in pressure roller and closes
Conjunction state；Then winding arm falls into place its Scroll, and starts cutter assembly cutting film, while Scroll starts to receive
Volume, then cylinder 733 is released by center arm, center winding roller 734 is pushed to exit in place, and center winding cylinder clutch is separated,
Center winding motor B732 is simultaneously stopped running, and the film after winding is moved to and unloads film pedestal, is affected by unloading film cylinder and unloads film bottom
Seat decline, other assemblies and roller group all reset, and center winding motor A731 starts operation, center winding cylinder clutch closure,
Film is normally collected.
When film collects diameter equal to 800mm, center winding motor B732 brings into operation, under the control of PLC in
The synchronous fortune of heart winding motor A731.When center winding motor B732 cylinder clutch is closed, center winding motor A731 moment point
Open form is normally wound at fast turnaround (FTA), film.Film, which collects diameter, under center winding motor B732 drive can receive 2000mm.
Certainly, illustrated above is only the preferred embodiment of the utility model, and the use of the utility model is not limited with this
Range, therefore, it is all made in the utility model principle it is equivalent change should be included in the protection scope of the utility model.
