PVC热收缩(一牵引旋转)吹膜机组

PVC thermal shrinkage (first traction) film blowing machine
  PVC热收缩一牵引旋转(印刷级)吹膜机组.是2013年研制成功的新颖吹膜机组,一牵引旋转是将原膜经过180~320度变位旋转.使制品保证平整无绉,夏天不易产生暴筋其目的,经过二年的正常生产,于2016年经过更新换代改造,2017年成功申请技术专利产品,称为“一牵引旋转第二代吹膜机组”(实用新型专利:专利号:ZL201620854318.0)

我公司从新对螺杆,机筒的改进设计,提高塑化增加挤出量,减小水温控制的互差,采用新一代可控硅智能数位功率调整控制,达到三相电网平衡,更有效在节能10~15%.还能延长电热棒使用寿命。
  PVC热收缩一牵引旋转是将原膜经过四级变位旋转,配备纠偏装置,使二次吹张保持直线度更好,制品厚薄更均匀,并达到了成品不会产生暴筋,提高了印刷速度。印刷可达到260-280米/分,是目前“PVC热收缩印刷级吹膜机组”工艺合理的机械。
  该机器技术指标先进、精度高,布局合理,结构新颖,操作方便 PVC印刷膜的吹膜设备.选用不同机型可生成品宽度:600-1200mm±2mm,.成品厚度:0.02-0.07mm±3mm,收缩率:纵向:3-5±1% 横向:45-50±2%,该机组生产的收缩膜主要用于标签等的印刷,印刷后的标签可以用于各类饮料、护肤品、化妆品等等各类商品的热收缩紧贴包装。


    
PVC thermal shrinkage a traction rotating (printing) blown film line. Was successfully developed in 2013 novel blown film machine, a rotating traction is the original film after 180 ~ 320 degree rotation displacement. Make products to ensure smooth crepe, summer is not easy to generate critical reinforced its purpose, after two years of normal production, after upgrading transformation in 2016, 2017 successful application technology patent product, known as "the second generation of blown film rotary unit

Our company has improved the design of screw and barrel, improved the plasticization, increased the amount of extrusion, reduced the temperature difference, adopted the new generation of SCR intelligent digital power adjustment control, reached the three-phase power grid balance, more effective in energy saving 10-15%, also can extend the service life of the electric heating rod.

PVC heat shrinkage traction rotation is the original film through four levels of displacement rotation, equipped with deviation correction device, so that the second blowing to maintain a better straightness, product thickness more uniform, and to achieve the finished product will not produce a burst, improve the printing speed.Printing can reach 260-280 meters/min, is the current "PVC thermal shrinkage printing stage film blowing machine" process reasonable machinery.

The technical indicators advanced machine, high precision, rational layout, novel structure, convenient operation of PVC printing film blowing equipment. Choose different models can be born finished width: 600-1200 - mm + 2 mm, thickness: 0.02 0.07 mm + / - 3 mm, shrinkage rate: longitudinal: 3-5 plus or minus 1% transverse: 45 to 50 plus or minus 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.
