In order to achieve the above purpose, the technical scheme of the utility model is that:

an open mill with a circulating feeding function comprises a first frame, wherein a pair of counter rollers are rotatably arranged on the first frame, and a first motor reducer in transmission connection with the counter rollers is arranged beside the first frame; a receiving disc which is inclined downwards is arranged below the counter roller, and an automatic feeding mechanism is arranged on the lower side of the receiving disc; the automatic feeding mechanism comprises a second rack, a first rotating roller is horizontally arranged in the second rack in a rotating mode, a second motor speed reducer is arranged beside the second rack, and one end of the first rotating roller is coaxially and fixedly connected with the output end of the second speed reducer; the inboard setting of second frame is arranged the leading truck of first commentaries on classics roller both ends in branch, the leading truck is facing incorgruous roller one side bending, and the lower extreme and the first roller fixed connection that changes of leading truck, the roller is changeed to the rotatable second that sets up in upper end, and the second is changeed the one end of roller and is connected with the third motor reducer transmission that sets firmly in the leading truck side, and the symmetry sets up the guide way on the medial surface of leading truck, and first commentaries on classics roller, second change and have the material loading area of coarse granule around establishing the surface on the roller, and the edge of material loading area inlays to be located in the guide.

Furthermore, the cross-section of guide way is the L type, and the lateral margin of material loading area is provided with the flange with the guide way adaptation.

Furthermore, barbs which are inclined along the advancing direction of the feeding belt are uniformly distributed on the surface of the feeding belt.

The working principle is as follows: when rubber and plastic are required to be mixed, a worker drives the second motor reducer to rotate, so that the guide frame is driven to be turned upwards to enable the material belt to be close to the counter roller. Then the second motor reducer stops rotating and the guide frame keeps the posture. The first motor reducer and the third motor reducer are then started. The rubber/plastic is extruded to the receiving disc from the upper part of the counter roller under the driving of the counter roller rotating in the opposite direction, then flows to move downwards along the inclined receiving disc to be contacted with the upward advancing feeding belt, the rubber/plastic is upwards carried by the feeding belt by a certain height because the surface of the feeding belt is provided with rough particles, when the feeding belt is closest to the counter roller, the rubber/plastic is extruded from the feeding belt and the counter roller to increase the friction force with the feeding belt, and then the rubber/plastic is driven to the upper part of the counter roller by the feeding belt. At this time, since the guide frame is bent toward the different-direction rollers, the rubber/plastic finally falls between the two different-direction rollers under the action of gravity. Whereupon the rubber/plastic returns to the original position for repeated rubber mixing operations. After the rubber/plastic connection is completed, the second motor reducer is driven to rotate and drive the guide roller to rotate to the horizontal state, and at the moment, the rubber/plastic on the receiving disc is taken out of the receiving disc by the advancing feeding belt to an external receiving mechanism (not shown in the figure).

Has the advantages that: through the structure, the feeding in the rubber mixing process of the open mill can be automatically completed through the automatic feeding mechanism, and the working strength of workers is greatly reduced.
