The principle and characteristics of shrink packaging machine

Abstract: the contraction packing machine is a kind of highly automated equipment, the products are widely used in food and beverage and household industries, application of shrinkable film packaging machine can greatly reduce the box packing materials and artificial cost, has the vital significance. Automatic shrink packaging machine is a kind of pneumatic components and the combination of mechanical device, is controlled by PLC and other peripheral circuit of automatic packaging equipment. The equipment of the air cylinder is is, by two five-way solenoid valve control the forward and backward, the working position of cylinder by the magnetic switch and proximity switch testing and feedback to the PLC, made by PLC programmed control command to the appropriate electromagnetic valve, cylinder to control the motion of the cylinder. Characteristic: the contracting process, does not affect the quality of packing materials, and can shrink rapidly perfect, can seal products, moistureproof, prevent collision tight packing, suitable for multiple items and pallet packaging. 1, using far infrared heating directly; 2, equipment, small size, short preheating time, save electricity; 3, the electronic stepless temperature adjustment; 4, contract does not affect the quality of the item packaging can shrink packaging perfect; 5, suitable for regular or irregular goods packaging
