The operation principle of the utility model is：In use, pressing lower air valve, first fixed in the inflation with fast aeration handle
Air-filled pore on seat is passed through compressed air, and compressed air is entered by main shaft gas channels, air admission hole pushes seat and skeleton oil
The confined space formed is sealed, compressed air pushes outside framework oil seal, pushes seat movement, compresses ejector spring, expanding block return will be rolled up
Core is put among modular gas expansion shaft；Fast aeration handle is used to release the compressed air in gas expansion shaft again, ejector spring return pushes away
Dynamic pushing block, outside framework oil seal movement, expanding block eject swelling core, complete feeding, unreeled；It unreels completion or needs to change object
When material, compressed air is passed through in the air-filled pore in inflation fixed seat with fast aeration handle, compressed air push outside framework oil seal,
Pushing block moves, and compresses ejector spring, and expanding block return carries out material replacement.
The utility model has the beneficial effects that：Be passed through compressed air push outside framework oil seal, push ring, compression retracteding position spring,
To push expanding block return, replacement barrel is carried out.Air is released, spring return function holds out against barrel.In wrapup procedure, swelling
Power is always consistent, and any influence will not be generated to winding tension, and the jacking block on same station finishes for the same workpiece
It forms, can ensure concentricity when core swelling well, the tension force between each station and main shaft is controlled by jacking block, it can be with
Ensure the consistency of each station tension force well and do not have an impact between each other, and then can be with high quality, efficient life
Production, ensure that the performance and yield of product.
