真空袋制作加工

　　自封袋印刷吹膜机的生产流程及生产原理：将干燥的聚乙烯粒子加入下料斗中，靠粒子本身的重量从料斗进入螺杆，当粒料与螺纹斜棱接触后，旋转的斜棱面对塑料产生与斜棱面相垂直的推力，将塑料粒子向前推移.

　　The production process and production principle of printing bag blowing machine: dry with polyethylene particles under the hopper, by weight of the particles from the hopper into the screw thread, when the aggregate and the oblique edge contact, oblique edge rotating plastic face and oblique edges face vertical thrust, the plastic particle goes forward.

　　推移过程中，由于塑料与螺杆、塑料与机筒之间的摩擦以及粒子间的碰撞磨擦，同时还由于料筒外部加热而逐步溶化。熔融的塑料经机头过滤去杂质从模头模口出来，经风环冷却、吹胀经人字板,牵引辊,卷取将成品薄膜卷成筒。用途与特点该设备采用双变频调速，可为你节约电能，本机组挤出机，机筒、螺杆均采用优质合金钢，紧氮化处理和精密加工，具有的硬度和耐腐蚀性，特殊设计的螺杆产量高，塑化好。适用于吹制低密度聚乙烯（HDPE）线性低密度聚乙烯（LLDPE）等塑料薄膜，广泛应用于食品、服装、垃圾袋、背心袋子等民用及工业包装。

　　In the course of migration, the friction between plastic and screw, plastic and barrel and the collision and friction between particles are also caused by the gradual melting of the outer heating of the barrel. The molten plastic is filtered through the head of the machine to remove impurities from the die head, cooling through the wind ring, blowing through the herringplate, pulling roller, and winding the finished film into the tube. Use and characteristics of the equipment adopts double frequency conversion, it can save energy for you, an extruder, cylinder and screw rods are made of high quality alloy steel, compact nitriding and precision machining has the best hardness and corrosion resistance, special designed screw with high yield, good plasticizing. It is suitable for blowing low density polyethylene (HDPE), linear low density polyethylene (LLDPE) and other plastic film. It is widely used in food, clothing, garbage bags, vest bags and other civil and industrial packaging.

　　低压聚乙烯（HDPE）和线形低密度聚乙烯（JJDPE）是国际市场上近年来大量生产的聚乙烯新品种。由于它具有优良的抗冲击强度，耐穿刺性，耐环境应力开裂，耐低温度性能，特别是可以制微薄膜（1.5丝厚的薄膜强度足可以抵提上3丝厚的高压聚乙烯薄膜）。使用成本低，因此大量用于吹塑薄膜。可吹制低压，高压，线形低密度三种聚乙烯薄膜，不但适应它们的新料吹膜，还适用于它们的再生塑料吹膜，性能稳定，质量可靠，本吹膜机采用特殊结构的螺旋杆挤出机，先进的螺旋模头，调节灵活的冷却风环，合理的光圈式稳泡结构，从而保证上三种聚乙烯及不同比例的混合塑料化均匀。

　　Low pressure polyethylene (HDPE) and linear low density polyethylene (JJDPE) are the new varieties of polyethylene produced in the international market in recent years. Because of its excellent impact strength, puncture resistance, environmental stress cracking resistance, resistance to low temperature performance, especially for micro film (to put on the thick wire 3 high pressure polyethylene film can be strong enough to 1.5 thick wire). Low cost of use, so a lot of use is used to blow plastic film. Can be blown low pressure, high pressure, three kinds of linear low density polyethylene film, not only to adapt to the new film blowing them, recycled plastic blown film, is also suitable for their stable performance, reliable quality, the special structure of film blowing machine adopts a screw rod extruder, screw die advanced, adjustable cooling wind ring flexible. Reasonable aperture type foam structure, so that the mixed plastic three polyethylene and different proportion uniform.
