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.)
1. Machine main frame
Gantry type frame, made of square steel tube, material: Q235 steel.
Driving motor base is installed on the frame.
The rotary arm is fixed on the frame connecting with slew bearing.
Frame size: (to be confirmed by drawing)
2. Driving device for rotary arm
Frequency control motor with brake
Brand of motor: Local famous brand, Power rated: 1.5KW
Rotary arm speed: n=25rpm (frequency motor with brake)
3. Film carriage
The film carriage is a dynamic pre-stretching mechanism, and the pre-stretching can reach 250% (1m to 3.5m).
The combination of the brand-new film carriage design and the unique encapsulation technology makes the stretching effect of the stretch film more uniform.
The rise and down speeds of the film holder and the film feeding speed can be adjusted separately.
The number of top and bottom wrappings are separately controlled.
Stretch film system follow-up mechanism, just pull it.
AC motor stretch film frame, frequency converter to adjust stretch film tension.
Film-out deceleration motor: domestic high-quality (frequency conversion speed regulation)
Motor power: 0.37 KW, local famous brand.
4. Film carriage lift 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, Local famous brand. Turbo worm reducer.
Film delivery following up mechanism.
The film delivery following up the rotary arm rotating, the proximity switch controls the start/stop of film delivery motor to follow up the rotary arm.
5. 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.
