1, screw extruder, spiral tube-based company 2, by matching the high reliability of the hardened gear box, low noise, "jingcheng" DM series of plastic film blow molding unit, by the extruder, single-layer blow die, cooling wind ring, traction machines, coiling machines, temperature and electric control systems, mainly used in the production of LDPE agricultural plastic film , the replacement of the necessary components, but also produces HDPE, LLDPE film. The family unit has the following structure, complementary features: 1, screw extruder, spiral tube-based company2, by matching the high reliability of the hardened gear box, low noise, high transmission efficiency, smooth operation, durable. 3, using the cylinder-type filters, for network cycle than ordinary nets for 7-8 times longer, not only to make up for a quick network device for easy leak material defects, can effectively extend the time for networks. 4, the first use of center-mode feed-type spiral flow channel, head for the high-quality carbon steel materials, multi-channel by heat-treatment process after deformation to a minimum. 5, traction roller, roller coiling Balancing all of detection, correction, precision grinding.6, on the use of short-chain rotational traction, not only solved the Direct-coupled anti-not easy, the problem of short life, but also to overcome the long chain of vibration, noise higher defects. 7, and automatic equipment in the autopsy of a long device. 8, with a double sprocket to facilitate the operation speed. 9, supporting the domestic electrical appliances are well-known brands
