polyimide film taping and sintering machine

polyimide film taping and sintering machine

polyimide film taping and sintering machine

polyimide film taping and sintering machine,taping polyimide film to magnetic wire and sintering.
Flat wire: 6x20mm

polyimide film taping and sintering machine,taping polyimide film to magnetic wire and sintering.

This machine is designed special for taping and sintering polyimide films to copper wires, round or rectangle.

The machine is duplicated with two same sections for higher productivity.

Each section has two mechanical constant-tension taping heads, one prograde and one obverse;

Take-up station is tension-trackslip type with damping. By this special take-up device, the wire will not be drawn smaller or thinner. The tension is manually adjustable.

Full closed shield, cover open/close driven by pneumatic.

If don’t use sintering machine, it can be used as normal paper wrapping machine.

Line Buildup

1) Pay-off: vertical or horizontal, chosen by Buyer

2) Main taping & sintering unit (inverter control speed)

- Operation worktable: covered by stainless steel

- Wire straightener: straightening rollers are made by MC Nylon

- Wire polisher: polishing upper and lower surface of the wire, to increase the surface adhesion capability.

- Film taping heads, two (one prograde and one obverse); The film disk is equipped with mechanical constant-tension device; It will automatically stop when film breaks off; Each wrapping head can load two film disks

- Shield for taping section: full-sealed structure, driven by pneumatic, with view window

-Towing device: towed by thickened synchronizing pedrail; Pressing wheels are circular-arc-tooth synchronized wheels.

- High frequency sintering machine: interlocked with main machine

- High-temperature resistant pressing wheel: stainless steel framework, silicon rubber coated

- Radiating stove: electric heating tube made by stainless steel, movement driven by linear rail

- Cooling water tank: welded by stainless steel

-Transmitting belt: synchronizing tooth-shape belt

3) Take-up device

-Take-up power: moment motor

- Wire-ordering: slick-rod wiring

Specifications

1) Main driving motor: 2 x 2.2kW inverter controlled motor, constant torque.

2) Suitable copper wire:

Flat wire: max. 6x20 mm

Round wire: diameter 1-6mm

3) Max. film disk diameter: 300mm, film disk inner diameter 75mm

4) Suitable film width: 8-20mm

5) Pay-off wire reel: diameter max. 800mm, width max. 650mm

6) Take-up wire reel: diameter max. 630mm, width max. 300mm

7) Taping pitch: 4~16mm, stepless adjustment

8) Rotating speed of the taping head: 0~560 rpm, stepless adjustment, wrapping heads are driven by synchronization belt.

9) Traction wheel diameter: 390mm.

10) Taping layers: each taping head can wrap two layers, each wire can be taped with 4 layers film.

11) High-frequency sintering machine: 2 x 40kW

12) Radiating stove: 1500mm long, two sets, heating power 3.6kW per set
