Figure 2 The slotting area of the No. 1 slot 11 can be larger than the plastic, but the large damp and caked plastic can be blocked, so that the effect of preventing large caked materials from falling can be achieved. The plurality of No. 1 slots 11 are distributed in a circumferential array. The lower side of the No. 1 blocking plate 10 is provided with a No. 2 blocking plate 13 fixedly connected to the inner side of the feeding barrel 1.

The upper side of the No. 1 blocking plate 10 is provided with five forward rake teeth 9 fixedly connected to the side surface of the transmission rod 8. The five forward rake teeth 9 are distributed in a circumferential array. When the caked plastic particles are blocked on the upper side of the No. 1 blocking plate 10 by the No. 1 slot 11, the rotating forward rake teeth 9 can push the caked materials to the side. In the process of repeatedly pushing and colliding the materials, the effect of crushing can be achieved. The upper side of the No. 2 blocking plate 13 is provided with five reverse rake teeth 12 fixedly connected to the side surface of the transmission rod 8. The five reverse rake teeth 12 are distributed in a circumferential array. One side of the cover plate 2 is provided with a transmission rod driving mechanism for rotating the transmission rod 8. The upper side of the cover plate 2 is provided with a material adding mechanism. The upper side of the forward rake tooth 9 is provided with a turbine flow guide mechanism.

[0021] Please combine Figure 1 The transmission rod driving mechanism comprises a No. 2 bevel gear 5 fixedly connected to the upper end of the transmission rod 8. One side of the No. 2 bevel gear 5 is provided with a motor driving mechanism for rotating the No. 2 bevel gear 5.

[0022] The motor drive mechanism includes a servo motor 3 fixedly connected to the upper side of the cover plate 2. The output end of the servo motor 3 is fixedly connected to a first bevel gear 4, which meshes with a second bevel gear 5.

[0023] Please combine Figure 1 As shown, the material adding mechanism includes a material inlet 6 opened on the cover plate 2. A sealing cover 7 is provided on one side of the material inlet 6 and is rotatably connected to the upper side of the cover plate 2. Plastic granules and other materials required for injection molding can be added from the material inlet 6. Then, the sealing cover 7 is closed by pushing the pull rod on the sealing cover 7.

[0024] Please combine Figure 3 As shown, the turbine diversion mechanism includes a retaining ring 17 fixedly connected to the inner side of the feeding barrel 1.

Under the action of gravity, the plastic granules initially flow downwards through the center of the turbine 15, reaching the upper side of the first baffle plate 10 and gradually being blocked. When the servo motor 3 is started, the servo motor 3 drives the second bevel gear 5 to rotate through the first bevel gear 4, which in turn directly drives the transmission rod 8 to rotate. The rotation of the transmission rod 8 directly drives the turbine 15, the forward rake tooth 9, and the reverse rake tooth 12 to rotate together. Under the action of the turbine 15 rotation, its… The plastic granules in the upper part of the barrel can fall at a certain speed to the center of the first baffle plate 10. At the same time, the forward rake teeth 9 use their own structure to push the plastic at the center of the first baffle plate 10 from near the center to the first slot 11 on the periphery of the first baffle plate 10. At this time, the plastic granules can fall from the first slot 11 and fall into the edge of the second baffle plate 13. Meanwhile, the rotating reverse rake teeth 12 use their own structure to push the plastic granules located on the outer edge to the center of the second baffle plate 13. At this time, the plastic can flow down from the second slot 14 of the second baffle plate 13, thereby achieving the purpose of feeding material into the injection molding machine chamber.
