ABA film blower enters the screw from the hopper. When the raw material contacts with the screw rib, the rotating oblique edge pushes the raw material particles forward. During the pushing process, the raw material gradually melts through the extrusion friction heating and external heating. The melted raw material is extruded from the die mouth, and then it is blown, cooled by the air ring, pulled up by the traction frame, pulled roll and passed through. Rewinding frame is rolled into thin film cylinder material.
In order to avoid accidental injuries to operators. When feeding, it is strictly prevented that hard materials with metal impurities and operating tools that damage the machine fall into the barrel. Never wear gloves when operating a rotating machine to prevent involvement. Check whether the instrument is damaged abnormally. Make sure all parts are safe and normal before starting, so as not to affect production and cause accidents.
Film blowers are divided into high-pressure blowers and low-pressure blowers according to raw materials. There are many kinds of film blowing machines, such as high and low pressure polyethylene double-purpose film blowing machine, high and low pressure polyethylene double-purpose film blowing machine, rotary machine head film blowing machine, high and low pressure ultra-thin film blowing machine, film blowing gravure printing connecting machine and so on. The problem of leakage caused by die rotation is avoided, and the quality problems such as the size of film coil head and the loose edge are overcome.
The smoothness of film winding is guaranteed. High precision die head and high efficiency double-tuyere air ring cooling system ensure the uniformity of film thickness, resulting in a high yield of qualified products. To learn more, depending on the weight of the particle itself, it enters the screw from the hopper. When the particle contacts the screw oblique edge, the rotating oblique edge produces a thrust perpendicular to the plastic oblique edge.
The plastic particles are pushed forward. During the pushing process, because of the friction between the plastic and the screw, the plastic and the barrel, and the collision and friction between the particles, the cooling system of the film blower should be strengthened in order to be more efficient. If the cooling is not enough, the internal cooling or water cooler or other cooling equipment should be used.
