Raw material batching device for plastic plate production capable of reducing backflow

The raw material batching device for plastic plate production capable of reducing backflow comprises a locking plate, locking frames are arranged on the two sides of the upper surface of the locking plate, the locking frames are arranged in an arc shape, and the arc opening directions of the locking frames face the circle center position of the locking plate; at least three supporting frames are vertically arranged outside the locking plate, an obliquely-arranged feeding plate is arranged at the upper ends of the supporting frames, the feeding plate is obliquely upwards arranged in the direction away from the locking plate with the fixedly-connected positions of the supporting frames and the feeding plate as the starting point, a plurality of feeding holes are formed in the feeding plate, and materials can be fed through the feeding holes. The feeding device has the effect that the backflow probability of materials passing through the feeding hole is reduced. 本申请涉及一种减少回流的塑料板生产用原料配料装置，其包括锁位板，锁位板上表面两侧均设置有锁位架，锁位
