[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] like Figure 1-5 As shown, in this embodiment, a high-efficiency feeding device of an extruder includes a sealing cover 2, a transmission shaft 7 is embedded and installed on the inner side of the sealing cover 2, a guide plate 701 is fixedly installed on the inner side of the transmission shaft 7, a second guide plate 702 is fixedly installed on the outer side of the transmission shaft 7, a mixing port 703 is symmetrically provided below the transmission shaft 7, and the mixing port 703 is connected to the transmission shaft 7, an extrusion disk 9 is provided on the inner side of the sealing cover 2, and the extrusion disk 9 is movably connected to the transmission shaft 7, a plurality of fan disks 901 are embedded and installed on the inner side of the extrusion disk 9, a telescopic rod 902 is embedded and installed on the inner side of the fan disk 901, and the telescopic rod 902 is fixedly connected to the extrusion disk 9, the transmission shaft 7 passes through the inner side of the docking tube 6, and the transmission shaft 7 extends out of one side of the docking tube 6, and the fan disks 901 are arranged in a fan shape to fit each other;

[0025] Specifically, through this arrangement, when in use, the transmission shaft 7 extending from one side of the docking tube 6 is fitted with the screw of the extruder. When the extruder is in operation, the screw rotates, and the threads on the screw are meshed with the threads on the transmission shaft 7 for transmission (similar to the connection relationship of bevel gears), thereby driving the transmission shaft 7 to rotate in the sealing cover 2. When the transmission shaft 7 rotates in the sealing cover 2, the mixing agent in the middle of the transmission shaft 7 is pushed to the mixing port 703 through the guide plate 701 under rotation and discharged, thereby mixing the mixing agent with the material in the feed hopper 1. Secondly, when the transmission shaft 7 rotates, the second guide plate 702 moves in the sliding groove 10, so that the extrusion disk 9 is moved in the sealing cover 2. The second guide plate 702 rotates and slides downwardly toward the bottom of the feed hopper 1. When the extrusion disk 9 slides, the fan disk 901 gradually contracts toward the inside of the extrusion disk 9. At the same time, the material in the feed hopper 1 is pressed down by the extrusion disk 9 and the fan disk 901, and then the material is transported from the docking tube 6 to the extruder. At the same time, the fan disk 901 prevents the material from hanging on the wall, so as to prevent the poor feeding effect of relatively thick materials and the uneven feeding caused by the material adhering to the inner wall of the feed hopper 1. When the extrusion is completed and the equipment stops operating, the fan disk 901 extends toward the outside of the extrusion disk 9 under the push of the telescopic rod 902, so that the fan disk 901 extends to the inner wall of the feed hopper 1 and slides upward to return to the upper position.

[0026] like Figure 1-5 As shown, in this embodiment, the sealing cover 2 is connected with the feeding hopper 1, and the upper sides of the feeding hopper 1 are fixedly installed with lock buckles 3, and the lock buckles 3 are connected with the sealing cover 2, and the lower side of the feeding hopper 1 is fixedly installed with a butt joint pipe 6, and the two sides of the butt joint pipe 6 are symmetrically installed with mounting blocks 4, and one side of the mounting block 4 is penetrated with a mounting hole 5;

[0027] Specifically, through this arrangement, when in use, the sealing cover 2 and the feed hopper 1 are fixed by the lock buckle 3 to prevent the sealing cover 2 from being lifted up by the operation of the screw of the extruder and the transmission of the transmission shaft 7. Secondly, the material in the feed hopper 1 is transported to the extruder through the docking tube 6 for mixing, stirring and extrusion. The feed hopper 1, the docking tube 6 and other equipment are installed and used with the extruder through the mounting block 4 and the mounting hole 5.

[0028] like Figure 1-5 As shown, in this embodiment, the guide plate 701 and the second guide plate 702 are equidistantly arranged around the inner and outer sides of the transmission shaft 7, the inner side of the extrusion plate 9 is provided with a sliding groove 10, the second guide plate 702 is movable through the inner side of the sliding groove 10, and a shaft cover 8 is fitted on the upper side of the transmission shaft 7;

[0029] Specifically, through this arrangement, when the transmission shaft 7 is rotated by the screw drive of the extruder, the mixing aid in the transmission shaft 7 is transported to the mixing port 703 through the guide plate 701 and discharged, and then mixed with the material. At the same time, the second guide plate 702 rotates in the sliding groove 10 to make the extrusion disk 9 gradually slide downward of the transmission shaft 7, and then the material in the feed hopper 1 is extruded and transported to the extruder. Secondly, the transmission shaft 7 is sealed by the shaft cover 8.

[0030] It should be noted that when the utility model is used as an efficient feeding device for an extruder, firstly, the feeding hopper 1 and the docking tube 6 and other equipment are installed and used with the extruder through the mounting block 4 and the mounting hole 5, and the sealing cover 2 is fixed to the feeding hopper 1 through the lock buckle 3 to prevent the sealing cover 2 from being lifted up by the transmission of the transmission shaft 7 when the screw of the extruder is in operation. Secondly, the material in the feeding hopper 1 is transported to the extruder through the docking tube 6 for mixing, stirring and extrusion. By fitting the transmission shaft 7 extending from one side of the docking tube 6 with the screw of the extruder, when the extruder is in operation, the screw rotates, and the threads on the screw and the threads on the transmission shaft 7 are meshed and driven, thereby driving the transmission shaft 7 to rotate in the sealing cover 2. When the transmission shaft 7 rotates in the sealing cover 2, the mixing agent in the middle of the transmission shaft 7 is pushed to the mixing port 703 through the guide plate 701 under rotation and discharged, and then The mixing aid is mixed with the material in the feed hopper 1. Secondly, when the transmission shaft 7 rotates, the second guide plate 702 moves in the sliding groove 10, so that the extrusion disk 9 slides toward the bottom of the feed hopper 1 under the rotation of the second guide plate 702. When the extrusion disk 9 slides, the fan disk 901 gradually shrinks toward the inner side of the extrusion disk 9. At the same time, the material in the feed hopper 1 is pressed down by the extrusion disk 9 and the fan disk 901, and then the material is transported from the docking tube 6 to the extruder. At the same time, the fan disk 901 prevents the material from hanging on the wall to prevent the poor feeding effect of the thicker material and the uneven feeding caused by the material adhering to the inner wall of the feed hopper 1. When the extrusion is completed and the equipment stops operating, the fan disk 901 extends to the outside of the extrusion disk 9 under the push of the telescopic rod 902, so that the fan disk 901 extends to the inner wall of the feed hopper 1 and slides upward to return to the upper position for continued feeding and use.
