5.2 General Description
1. Packaging line composition
A. 1 set of control system
B. 1 set of roller conveying stretch winding packaging machine
C. 1 set of automatic film feeding and breaking system
Package product specification: 1000 * 1000 * 1200 weight: 600kg
2. Packaging line action process
(1) The conveying line conveys the product to the winding machine position, manually thread the film and lead it out into the film feeder to clamp the film (only the first cycle requires manual film feeding, and the equipment will automatically apply the film later), set the parameters and start the winding machine for packaging.
(2) After packaging, the automatic film feeding and breaking system will automatically feed, break and brush the product, and the whole process is completed,
(3) When the roller conveying system is started, the products will be transported out automatically to complete a cycle. Repeat the above actions for continuous packaging.
(1) Technical parameters
Wrapping specification: 1000 * 1000 * 1200mm
Packing efficiency: 20-50 Torr / h
Power / voltage: 2.3 kW / AC 220V
Bearing capacity: 600kg
Overall weight: About 800kg
(2) Equipment composition
a) Turntable components
It is composed of chassis and turntable and adopts roller to transport goods
Turntable height: 400mm (height or customized)
Turntable rotation diameter: 2000mm
Turntable speed: 0-12rpm, speed variable frequency adjustable, turntable can be accurately positioned
Roller conveying speed: 10M / min
Rotary table reducer: Power: 0.75KW, reduction ratio: 1:40
b) Lifting column:
Double chain structure, the chain adopts 08B standard roller chain
Lifting speed: 0-56mm / s, frequency conversion adjustable
Lifting reducer (turbine reducer) power: 0.37kw
c) Membrane support system
Pre stretched film frame: the stretching ratio is 1:2.5, automatic film feeding, and the film feeding speed is adjustable.
It is convenient to pull out the film, and the film breaking frame will automatically stop running.
DC film feeding motor, power: 0.23kw
d) Automatic film feeding and breaking system
e) Electric control system:,
PLC programmable control, winding layers and times are adjustable, and the height of goods is automatically sensed.
Stepless frequency conversion speed regulation is adopted for turntable rotation, roller conveying and membrane frame lifting, which is convenient to operate
Easy to control the packaging effect.
