PVC heat shrink a traction rotary (printing grade) film blowing machine.
The novel film blowing machine was developed in 2013.A traction rotation is to rotate the original membrane through a displacement of 180~320 degrees.Make sure that the product is smooth without crepe, and it is not easy to produce sudden reinforcement in summer.After two years of normal production.After upgrading and renovation in 2016, we successfully applied for the technical patent product in 2017, which is called "the first traction rotary second generation film blowing unit".
Our company improves the design of screw and barrel, improves plasticization, increases extrusion, and reduces the difference of water temperature control. The new generation of SCR intelligent digital power adjustment control is adopted to achieve the balance of three-phase power grid, and the energy saving is 10-15% more effectively. It can also extend the service life of electric heating rod.
PVC thermal shrinkage and traction rotation is to rotate the original film through four levels of displacement, equipped with deviation correction device, so that the second blowing maintains a better straightness, the product thickness is more uniform, and the finished product will not produce sudden reinforcement, improve the printing speed.The printing can reach 260-280 meters/min, which is the most reasonable machine for "PVC thermal shrinkage printing grade film blowing machine" at present.
The machine technical indicators advanced, high precision, rational layout, novel structure, convenient operation with the international advanced level, is currently the most ideal and advanced PVC printing film blowing equipment. Choose different models can be born finished width: 600-1200mm±2mm, the thickness: 0.02-0.07mm±3mm, shrinkage rate: longitudinal: 3-5±1%, transverse: 45-50±2%, the unit production of shrink film is mainly used for label printing, after printing labels can be used in all kinds of drinks, skin care products, cosmetics and so on the thermal contraction close to packaging of all kinds of goods.
