The utility model discloses a crushing device for
high polymer material
processing, which belongs to the technical field of
high polymer material
processing and comprises a crushing box, a first motor is mounted at the top of one side of the crushing box, a
transmission belt structure is arranged on the first motor through an output shaft, and the
transmission belt structure penetrates through the crushing box and is provided with two cams. According to the crushing device for
high polymer material
processing, by arranging a first motor, a
cam, a fan and a ventilation net, a movable frame drives a processing
barrel to move up and down outside a sliding rod, so that a high
polymer material in the processing
barrel is driven to move in the processing
barrel and is
cut by a crushing blade, and meanwhile, the fan drives air to flow towards the processing barrel; and air penetrates through the ventilation net outside the processing barrel to enter the processing barrel, so that the high
polymer material moving in the processing barrel is cooled, the high
polymer material is prevented from being melted and adhered to the crushing blades, and the crushing efficiency of the device on the high polymer material is ensured.
