About the three-tier co-extrusion blown film machine equipment considerations must know

Three-tier co-extrusion blown film machine in the production of PE heavy packaging film has the excellent properties of single-layer PE membrane can't compare with. On the applications of the materials have a wide range of selective, can fully reflect the different levels of function, has good strength and toughness, open sex, moisture resistance, transparency, and heat sealing performance. Widely used in chemical raw materials, packaging, food, fertilizers and other commodities are suitable for all kinds of bags, bags, garbage pickup bag production, also can be used as a basic material printing, compound, has a large market. Domestic existing companies launched plastic packaging film equipment, mainly including three layers co-extrusion blow molding packaging film line and five layers co-extrusion heavy package film. Three of the thin film production technology is mature, have adopted conical stack and flat nose, level of traction rotator, automatic winder, corona processor, and rectifying device in cold system, etc. Adopt automatic weighing and feeding system, the domestic most online thickness and automatic wind ring and PLC control system, some manufacturer with five layers co-extrusion heavy package film.

Three-tier co-extrusion blown film machine in the process of heating equipment 3 to 4 hours should check whether each heating part and voltage ammeter pointer is normal, normal maintenance in time if you have any questions. Starts, the host at a speed of 15 to 20 RPM boot, observing the situation of material plastication, the pressure of the host, current is normal, it is forbidden to heat to forcibly boot (such as heating is not enough to lead to mold dislocation and film thickness). Operators in the process of production may not be far away from the winding area, to prevent accidental situation is not timely detection and treatment, and pay attention to the placement of knife and winding, safety first. 4. Clean mouth and change the screen, good protective gloves should be worn, pay attention to the nose section of the terminal with bare parts, to avoid being electrically damaging; Cleaning membrane mouth and change the screen must be used when copper shovel, in order to avoid injury and membrane mouth and change the screen, at the same time when the outage of net pay attention to efficiency, the grasp of time, temperature is unfavorable to avoid affecting blown film work next time. In boot membrane in the process of attention not to put his hand into the roller, and banned gloves.
