<p>A rubber kneading machine, comprising two rolls (1, 2) horizontally and closely disposed in vertical direction, speed reducers (16a, 16b) and variable speed motors (15a, 15b) for variably rotating these rolls, a screw extruder (3) for supplying rubber lumps charged into a hopper (4) at a base end between the rolls, a rubber circulating mechanism having a scraper (33) and a belt conveyor (34) or a belt conveyor (35) over the upper roll (1) for feeding a rubber sheet delivered from the rolls (1, 2) to the hopper (4), and a screw extruder (3) opening mechanism to open and expose the inside of the closed part of a rubber feeding mechanism for facilitating cleaning, whereby a worker must not bring a rotating roll surface into contact with rubber for rubber kneading operation, unmanned operation is also allowed substantially safely, a productivity can be increased in a rubber kneading process, the quality of kneaded rubber can be stably assured, and the rubber feeding mechanism of closed structure can be easily opened and exposed for facilitated cleaning.</p> |
