2, Functional description of each part:
1. Unwinding section:
1. The unwinding adopts a shaftless hydraulic cone top, which is
convenient for single person operation. Adopting a special conical
top form, it does not damage the inner wall of the pipe core. The
3-inch and 6-inch mechanical expansion sleeve locking devices are
sturdy and durable. The left and right clamping arms are
hydraulically controlled by a dovetail groove linear guide rail.
Two hydraulic clamping cylinders, left to right, separate
simultaneously, making clamping operation extremely convenient.
2. Two hydraulic powered loading and unloading oil cylinders can
withstand a weight of 3 tons of raw materials, saving manpower and
shortening loading and unloading time.
3. The unwinding diameter is automatically detected by the
proximity switch at the unwinding transmission shaft, and there is
no need to input material thickness. The residual unwinding
diameter can be set to automatically slow down and stop, making it
easy to receive the next roll of material. The unwinding tension
adopts a sensor closed-loop automatic taper tension control mode
through Siemens PLC.
4. Equipped with a mechanism for manually adjusting the release and
tightening edges, with an adjustment range of ± 20mm.
5. The material is automatically corrected by the automatic
deviation correction system. The entire frame adopts a guide rail
type left and right movement, and the moving part adopts a threaded
screw rod, which is pushed left and right by a servo motor to
achieve automatic deviation correction.
8. The unwinding adopts pneumatic brakes.
It should be controlled by SMC precision proportional valve.
4, Host part:
1. The rack adopts 80 # high-quality castings in a frame structure,
and the entire machine is supported by seamless hollow steel pipes.
The horizontal and straight beams are segmented in the middle for
easy disassembly and transportation.
2. The host adopts a combination of servo motor and synchronous
wheel speed ratio for transmission.
3. The traction device adopts active traction and pneumatic
compression method. The servo motor drives the mirror roller to
actively pull.
4. The entire machine adopts closed-loop servo motor control.
5, Roll up section:
1. The winding adopts a dual structure of surface winding and
center winding, with front and rear winding in the form of A/B axis
winding. The motor drives the reducer to wind (or single axis
rewinding is also possible)
2. The winding mechanical arm adopts an imported dovetail groove
linear guide rail structure form
3. Principle of surface winding form, with the winding shaft
tightly attached to the steel shaft for synchronous winding (the
steel shaft is driven passively)
4. Each winding shaft is driven by a 15kw servo motor, and the
winding tension is adjusted based on the current material winding
diameter by Siemens PLC automatic control frequency converter to
adjust the tension of the expansion shaft, so that there is no
thickness factor in multiple cut materials, and all coil end faces
are flat.
The flatness of the disc surface is freely selected by switching
between pneumatic pressure and self weight pressure, and the
tightness of the inner and outer layers of the finished coil is
controllable. As the winding diameter continues to increase,
Siemens automatically controls the speed of the winding servo motor
by PLC, greatly extending the service life of the servo motor.
5. When single axis rewinding is required, the full axis tension
can also be selected on the touch screen, and the winding servo
motor is used as the rotating cone control mode.
6. Winding and unloading form: hydraulic automatic unloading
7. Waste edge recycling device: The edge collection device collects
waste edges
