Abstract

This utility model belongs to the field of waste plastic film recycling technology, specifically a waste plastic film impurity separator. It includes a separation component that continuously separates different impurities of varying mass and volume from the plastic film. A feeding component is provided on one side of the separation component to cut the plastic film fed into the separator. Inside the separation component is a crushing component that segments the plastic film and impurities during its movement. This utility model facilitates the use of a screening element on the outer side of the rotating drum and a spiral guide plate inside the drum. This allows the rotating drum, driven by a drive unit, to continuously rotate and laterally move the segmented plastic film fed by the feeding component. Combined with the collection component and crushing component, different types of impurities contained in the plastic film can leave the rotating drum sequentially when they reach the positions of the first and second filter plates. This allows the separator to continuously process plastic film while ensuring effective impurity removal.

Description

Waste plastic film impurity separator

Technical Field

The utility model belongs to the technical field of waste plastic film recovery, and particularly relates to a waste plastic film impurity separator.

Background

The greenhouse film is a plastic film material for covering an agricultural greenhouse, and is not only beneficial to environmental protection, but also can generate great economic value if the greenhouse film can be recycled when the greenhouse film is aged and waste after being subjected to sun-drying and rain-spraying and can not be used. However, the plastic film of the greenhouse is usually used outdoors, and the edges of the plastic film are buried by soil, so that in the recycling process, the plastic film can carry a lot of soil and stones besides dust and dirt attached to the surface of the plastic film, and the impurities are difficult to separate after being mixed with the plastic film.

The chinese patent document with the publication number CN221021920U discloses a waste plastic film recycling device, which puts the recycled plastic film into the device body from the feeding port, and simultaneously starts the servo motor, the blower, the dust collector and the unidirectional motor to crush, winnow and screen the falling plastic film, thereby reducing the residual soil in the plastic film and reducing the influence of dust generated by crushing and screening on human body.

However, in the prior art, the recycling device can separate impurities such as floating ash, soil particles and the like with lighter mass from the plastic film, but impurities such as soil clusters, stones and the like with heavier mass are difficult to separate effectively, and the device has limited capacity, and when more plastic films need to be treated, the recycling device can be used only after batch, so that the waste plastic film impurity separator is provided.
