With the wide variety of plastics and the rapid increase in quantity, the amount of waste plastic films is also increasing. Therefore, the recycling of plastic films has received widespread attention from all over the world. The recycling of waste plastic films can not only save a lot of raw materials and energy, but also help prevent environmental pollution. During the recycling process of waste plastic film, the waste plastic film itself will be stained with oil, dust, sand and printed marks to varying degrees, and if these impurities are not cleaned up, it will affect the quality of recycled products, so it must be Clean up. The usual cleaning process is to put the waste plastic film in a sink for rinsing or cleaning, use manual stirring to remove the impurities attached to the surface, and then clean it. If the plastic film is not cleaned cleanly, it will affect the regeneration quality. In recent years, mechanical cleaning and ultrasonic cleaning have appeared. The cost of ultrasonic cleaning is too high, and its popularization and application are limited. Mechanical cleaning generally uses mechanical cleaning machines, which also add chemical reagents to the body by stirring, which will cause Secondary environmental pollution, and the cleaning efficiency is not high, and the promotion is also limited.

For this reason, Chinese invention patent application number CN201110367786.7 provides an energy-saving and high-efficiency plastic cleaning machine, including a body, a screw rod is arranged inside the body, the screw rod is connected to a motor outside the body, a feed inlet is arranged on the upper part of the body, and a sewage discharge is arranged on the lower part of the body The right side of the body is equipped with a material guide pipe, and a water tank is installed under the material guide net.
