Rotary Arm Pallet Wrapper With Top Sheet Dispenser
Arm rotary wrapper with sheet dispenser to apply top sheet onto pallet. The pallet is wrapped on 5 sides for better water-proof and dust-proof. Arm wrapper with top sheet dispenser is excellent choice for pallet loads that need long term storage or long distance transportation. Especially for high speed production line.
Rotary arm stretch wrapper with sheet dispenser, the sheet dispenser is combined into pallet wrapper to apply top sheet onto pallet during wrapping progress. Save space and more functional.The pallet is wrapped on 5 sides for better water-proof and dust-proof. Arm wrapper with top sheet dispenser is excellent choice for pallet loads that need long term storage or long distance transportation. Especially for high speed production line.
Top sheet dispenser applies film sheet inside layers when palletising. For better protection of pallet loads.

Driving device for rotary arm
Frequency control motor with brake, power rated: 1.5KW
Rotary arm speed: n=15rpm (frequency motor with brake)
Two position limits equipped on two ends of rotary arm
Film carriage
Open-door type pre-stretch film carriage, stretch ratio 200% (1m to 3m)
Film carriage lifting driving: chain driving, good stability and high reliability
Driving reducer: worm gear reducer
Motor power: 0.37kw
Film carriage delivery device
The photoelectric switch is installed on the film carriage, automatic detect the height of the pallet
Driving motor: AC motor, speed adjustable
Power rated of film delivery driving motor: 0.37KW
Film delivery following up mechanism
The film delivery following up the rotary arm rotating, the proximity switch control the start/stop of film delivery motor to follow up the rotary arm
Film auto feeding and cutting device
When stretch wrapping finish, the film will be cut and clamped automatically.
When the film tail is released from the clamp, the air shooter will blow the film tail up, then the film tail will be wrapped by stretch film and keep it tightly with the pallet to ensure no film tail produced.
Film hot melt cutting adopts electrical heating wire to cut the film.
After film being cut, the hot sealer will seal the film tail automatically to ensure no film tail come out.

Film roll is placed upper ground, auto film cutting;
Pneumatic control system
Air source required: the compressed air shall be supplied by end user to the inlet of the stop valve.
The pneumatic cylinder is controlled by control box.
Safety interlock device
Start-up of the rotary arm & conveyor
The safety fence has the function of power cut when the door be opened. (For option of safeguard fence)
Electrical control system
PLC control system, the wrapping layers, the wrapping cycles, and the time of top wrapping.
8 programs can be set in the PLC system for different packing options.
The safety command can be added on the control program, add PLC extension module to ensure the safety of the machine.
The operating parameter can be set on Siemens touch screen, more convenient for operation.
Photo eye will detect the height of the pallet automatically.
Slewing bearing driving the rotary arm, high precision positioning.
The driving speed of rotary arm, roll conveyor, film carriage lifting are adjustable individually, the film delivery speed is also adjustable, equipped alarm for film break.
The wrapping machine is powered with pause/manual/automatic wrapping switch function, in order to ensure the better operating.
The machine is equipped with running warning light.
The machine is equipped with Ethernet interface, used for outputting the related information of the wrapping machine (Include the production quantity, mechanical efficiency, fault information etc.)
