The actual working temperature of three-layer co-extrusion film blower in each region is compared according to the temperature control parameters. Secondly, we should adjust the formula, speed, production environment and staff's working skills. We should improve and maintain the equipment carefully and carefully. It is the foundation to ensure the qualified and ideal products. Whether it is related to some gears or not is very important for judging the transmission failure, if a certain gear rings.
It must be related to the parts that affect the transmission of this gear; if all gears are noisy, it is often the fault of the gear shaft with constant mesh or the oil shortage of the transmission. Whether it is related to specific actions, such as adding, reducing gear, starting, accelerating, decelerating and turning, are all effective means of judging abnormal sound. Among them, changing speed and direction is particularly important for judging rear axle fault. If the abnormal noise of the transmission is obvious, it is recommended to send the professional maintenance plant to check out the faulty parts.
Then replace it. In the process of pushing, the melted material is gradually melted by extrusion, friction, heating and external heating. The melted material is extruded from the die mouth, and then is blown, cooled by air ring, pulled up by the traction frame, pulled up by the traction roll and rolled up by the reeling frame to form thin film barrel material. By adjusting the speed of main motor and traction motor to produce different specifications of products to reduce the impact of starting on the grid, starting current can be controlled within the rated current does not constitute a voltage impact.
hanging material, the temperature should be adjusted according to material property (there is difference between the temperature of return material and pure material). After changing mesh, the extrusion quantity of paste should be increased. That's to loosen the thin side and tighten the thick side. This is called inversion. There are four or six adjusting bolts in the die head, which are usually hexagonal. At the upper edge of the die, adjusting them can be done, as to whether it is tight or loose.
