Description

Technical Field

[0001] The utility model relates to the technical field of plastic film production, and specifically relates to a crushing device used in the production process of plastic films. Background Technique

[0002] A plastic film crushing device with the authorization announcement number of "CN213290992U" includes multiple horizontal first crushing knives, at least one mounting rod, multiple vertical second crushing knives and a mounting component. The rotating shaft vertically penetrates through the top of the crushing box and is arranged inside the crushing box. Multiple first crushing knives are all fixed on the rotating shaft. The mounting rod is arranged on the rotating shaft and is located below the first crushing knives. One end of the mounting rod is rotatably connected to the rotating shaft. The mounting component is arranged between the other end of the mounting rod and the inner wall of the crushing box to be used for enabling the mounting rod to rotate synchronously with the rotating shaft and driving the mounting rod to rotate self. Multiple second crushing knives are all fixedly connected with the mounting rod. The structure of the utility model is simple and is mainly used for crushing and processing plastic films.

[0003] This device can achieve sufficient cutting and crushing of plastic films. However, due to different materials of plastic films, during the crushing process, the plastic films may adhere to the surfaces of the crushing knives, resulting in poor subsequent crushing effects. Moreover, this device does not have a cooling structure. During use, certain friction will occur between the cutting knives and the plastic, causing the temperature of the cutting knives to rise, affecting the service life of the cutting knives. And during the cutting process of the overheated cutting knives, the crushing quality of plastic films with relatively low melting points will decline, and a good crushing effect cannot be achieved, resulting in certain limitations in the use of the device and low practicality and applicability of the device.
