[0002] Plastic films are widely used in people's daily lives. Most of the films are made of polymer materials, which are difficult to degrade after being discarded, causing great pollution to the environment. Therefore, the films need to be recycled after use.

[0003] A large number of plastic films are used in agricultural production, such as agricultural films and sunshade nets used in vegetable greenhouses, and mushroom stick packaging films used in mushroom cultivation. These plastic films are usually mixed with sand and various humus after being damaged and abandoned, making them very difficult to sort. Therefore, the films need to be recycled and reused. Since there are a large number of impurities in the films, impurity removal operations are required before secondary use. Although it is currently possible to separate the films from impurities by blowing air on the films to achieve the effect of impurity removal, there are still some defects in actual use. Since the films are relatively thin, the films are scattered everywhere after separation, causing the staff to collect the impurity-free films one by one. This process is rather cumbersome, and the scattered films are prone to secondary impurities.

[0004] Therefore, there is an urgent need to provide a film recovery and impurity removal device that can automatically collect the film. Utility Model Content

[0007] Furthermore, it also includes a connecting rod, a push plate and a second elastic member. The push plate is slidably arranged on the impurity removal frame, the push plate is connected to the connecting rod, and two second elastic members are connected between the push plate and the impurity removal frame.
