Waste plastic film impurity separating machine

Abstract

The invention discloses a waste plastic film impurity separating machine which comprises a machine frame. The waste plastic film impurity separating machine further comprises a screening drum, a pushing main shaft, a feeding mechanism and an impurity discharging device, wherein openings are formed in the two ends of the screening drum. The screening drum is axially and horizontally installed on the machine frame in a rotary mode, one end of the screening drum is a feeding end, the other end of the screening drum is a discharging end, a plurality of screening holes are formed in the circumferential wall of the screening drum, a spiral pushing blade is arranged on the inner circumferential wall of the screening drum, the screening drum is in transmission connection with a screening drum rotation power device, the pushing main shaft is installed on the machine frame in a rotary mode and axially penetrates through the center of the screening drum, a spiral auxiliary pushing blade is arranged on the pushing main shaft, the pushing main shaft is driven by a main shaft rotary device, the feeding mechanism is arranged at the feeding end of the screening drum, and the impurity discharging device is arranged at the bottom of the screening drum. According to the waste plastic film impurity separating machine, automatic and continuous separation of film impurities can be achieved, the efficiency for separating films from the impurities is accordingly improved, the waste plastic film impurity separating machine can be used in a film recycling production line, and the mechanical degree is high.

Description

technical field [0001] The invention relates to a plastic machine, in particular to a waste plastic film impurity separator. Background technique [0002] In the current plastic machinery industry, how to remove impurities in films has always been a difficult problem, especially the removal of impurities in agricultural films. Agricultural film refers to the film used in agricultural production. For example, a large number of films are required in vegetable greenhouses. These films are aged and unusable after being exposed to the sun and rain. However, the amount of agricultural film is very large. If the agricultural film can be recycled and reused Membrane, it is not only beneficial to environmental protection, saving materials and energy, but also can generate great economic value. However, since the agricultural film is generally buried with soil at the edge to cover the greenhouse, a lot of soil and stones will be carried during the recycling process of the agricultura...

AI Technical Summary

Problems solved by technology

However, since the agricultural film is generally buried with soil at the edge to cover the greenhouse, a lot of soil and stones will be carried during the recycling process of the agricultural film. These impurities are difficult to clean after being mixed with the agricultural film, thus becoming a part of the agricultural film recycling process. major problem

At present, there are two commonly used methods: one is manual selection, and the other is intermittent screening by using a screen. The degree of automation of these two methods is very low, and it is impossible to achieve rapid and continuous separation. Unable to apply to agricultural film recycling production line
