Keep in mind the attention of the film unit

Double - layer coextruding film extruder is a double - double - extruded plastic thin film extruder, which is used to blow down the plastic composite film, such as LDPE, HDPE and LLDPE. Widely used in liquid packaging, printing base material, export product packaging, industrial packaging, etc.

The energy saving of the film blowing machine can be divided into two parts: the power part and the heating part. Energy-saving power parts: mostly adopts frequency converter, motor energy saving way is by saving more energy, the real power of the motor is 50 hz, for example, and in production, in fact, you only need 30 hz enough production, that extra energy is wasted, the inverter is to change the motor power output to achieve the effect of energy saving. Heating part energy saving: most of the energy saving is energy saving with electromagnetic heater, the energy saving rate is about 30% to 70% of the old resistance circle.

The operator can not stand in front of the operation machine of the dalian blower, so as to avoid accidental injury and operator. In the feed, the hard material with metal impurities and small tools in the raw material will fall into the cylinder. Gloves are not allowed when operating rotating machines in case of injury. Check and add the lubricating oil in the gearbox and air compressor to check the lubrication of each mechanical transmission parts. Avoid drying and damaging machinery and making noise.

When starting up operation, check whether the power connection of each circuit is disconnecting and leakage. Check whether the equipment is damaged or not. Ensure the safety of all parts before starting up, so as not to affect production and accidents. In the condition of film forming, the forming temperature, cooling air temperature and blowing ratio are improved. Then the film turbidity increases, the gloss decreases; Instead, improve.

Die discharge uniform, can wear gloves slowly lift tube billet, pipe end will be closed at the same time, the micro into gas regulator, from central hole of the plug in a small amount of compressed air, and then carefully stiff foam frame, plates, and wear into the traction roller, guide roller and coiling (e.g., to be embossed after embossing roll). The compressed air pressure of the billet should be proper, so as to ensure the symmetrical stability of the tube and ensure the production of quality. Copper knife, rod or compressed air can be used to clean extruder and die, but avoid damage to screw and screw surface.
