Description
Technical Field
The utility model relates to a wind ring controlling means, in particular to blown film wind ring automatic control device.
Background
The air ring is an important component of a plastic processing machinery film blowing machine set and is responsible for cooling and shaping blown film bubbles. The wind ring has a great influence on both the quality and the yield of blown film articles. The device is also widely applied to labyrinth type drip tube belt units in recent years; the wind ring is in a circular ring structure and is cast by aluminum alloy. Due to the casting difficulty and the cast aluminum strength problem, the large-scale wind ring adopts a method of welding an embedded cast aluminum part by a shell steel plate. The wind ring is structurally divided into: the air inlet, the air exchange body, the rotator and the upper and lower lips (air outlet). The air inlets are even number, are uniformly distributed at the lower part or the side surface of the air ring, and are connected with the fan air distribution bag through air pipes. The wind trades the main part for hollow casing, and the cross-section is labyrinth, and built-in guide vane plays the effect that the homogenization air current established the atmospheric pressure. An air outlet is arranged between the upper lip and the lower lip, and air flow is blown out in 360 degrees. The lip is angled to control the angle of contact of the air stream with the bubble. The upper lip is fixed on the rotating body and can rotate up and down to adjust the size of the air outlet.
The original film blowing machine generally improves the air quantity of an air ring and the position adjustment of the air ring of the film blowing through manual observation, has strong technical dependence on production workers, needs the film blowing workers to have rich production experience and technical capability, has unstable production condition, and has longer time for adjusting film bubbles and poor stability; the swing, the shape and the size of the blown film bubble are generally judged by the experience of a film blowing worker, manual adjustment is carried out, and the requirements on the technical requirements and the capability of the user are higher.
