Description

Technical Field

[0001] The utility model relates to the technical field of film blowing waste treatment, in particular to a film blowing machine waste recycling device. Background Art

[0002] At present, the existing film blowing equipment will produce some excess scraps during the production process, but directly discarding them will not only produce more garbage and cause pollution, but also cause waste of resources. The recycling granulation device can effectively reuse the resources and has higher economic value.

[0003] The problem with the existing technology is that the waste of film blowing is recycled after being crushed, but the crushed waste has the phenomenon of flying due to its small size and light weight. In particular, when the crushed waste and plastic particles enter the extruder for secondary film blowing together, the crushed waste is difficult to be evenly mixed with the plastic particles. During the stirring and conveying process, the crushed waste will fly and concentrate on the upper layer of the mixed material, resulting in uneven density distribution of the molten material extruded by the extruder, and stratification of new plastic particles and crushed waste, which in turn leads to uneven quality of the blown film.

[0004] Therefore, in the secondary utilization of blown film waste, it is necessary to design a device to evenly mix the crushed waste and new plastic particles and input them into the extruder to ensure the uniform quality of the blown film output. Utility Model Content
