Environment-friendly film blowing machine for plastic production

The environment-friendly film blowing machine for plastic production comprises a rack, a feeding hopper, a film blowing mechanism and a fan, the feeding hopper is arranged at the upper end of the rack, a filtering mechanism, a smashing and impurity removing mechanism and a collecting mechanism are arranged in the feeding hopper, a motor is arranged in the rack, an auger is arranged on the side face of the motor, and the film blowing mechanism is arranged on the side face of the auger. The auger is arranged in the rack; in the process of feeding materials into the feeding hopper, the filtering mechanism can filter and collect the materials, so that the phenomenon that the materials cannot be completely melted due to the fact that the large granular materials flow into the device is avoided, defects in finished products are avoided, and after feeding is completed, the filtering mechanism can drive the large granular materials to move, so that the defects in the finished products are avoided. And the crushing an
