[0019] 1. The dust removal mechanism in this invention is the key to controlling dust pollution during the film crushing process. The transmission shaft is driven by a hydraulic motor to rotate, driving the fan to suck the dust generated by the film crushing in the box into the air outlet duct and discharge it into the factory exhaust gas treatment system to prevent dust from overflowing and polluting the working environment. The filter prevents the film fragments from entering the air outlet duct to ensure the normal operation of the exhaust gas treatment system. At the same time, when the transmission shaft rotates, the cam pushes the movable plate to drive the scraper to move left and right to clean the film fragments adsorbed on the bottom of the filter; the spherical top block, spiral slide rail, bracket and first spring cooperate with each other to insert the ejector pin into the filter hole to eject the blocked impurities, ensure the smooth flow of the filter, maintain a good dust removal effect, and ensure the stable operation of the equipment.

[0020] 2. The invention reduces the impact of static electricity on film crushing through the combined action of the spraying mechanism and the swinging mechanism. In the spraying mechanism, the transmission shaft drives the stirring rod to rotate, and intermittently pushes the slider to make the antistatic additive in the material tank fall evenly into the water tank. After mixing with water, the electric nozzle is swung through the first gear, the second gear and the torsion spring, and sprayed onto the surface of the electric crushing roller through the electric nozzle. The conductivity of water and the antistatic additive work together to conduct static electricity on the surface of the electric crushing roller, prevent plastic film fragments and dust from adhering to the surface of the electric crushing roller, reduce film entanglement and dust adhesion caused by static electricity, and improve the crushing effect.

[0021] 3. The swing mechanism in the invention ensures uniform feeding of the film and improves the crushing efficiency and quality. The transmission shaft rotates to drive the first bevel gear, which meshes with the second bevel gear, drives the third horizontal axis to rotate, and drives the second horizontal axis to rotate through the pulley, so that the push plate rotates, and the film at the feed port is evenly pushed onto the electric crushing roller to avoid insufficient crushing caused by film accumulation or uneven feeding. At the same time, the first gear on the third horizontal axis cooperates with the second gear on the first horizontal axis to swing the electric nozzle, spraying antistatic agent on the film during the feeding process, further reducing static electricity on the film surface, optimizing the crushing process, and improving crushing efficiency and product quality.

At this time, the slider 609 cannot block the bottom end of the feed pipe 607, and the antistatic additive in the material tank 606 will fall into the water tank 601 through the feed pipe 607. As the stirring rod 6012 continues to rotate, it will be out of contact with the protrusion 6011.
