[0020] The embodiment of the present application discloses a feeding device for an injection molding machine. Refer to Figure 1, including a transfer pipe 1 that can transfer raw materials. The upper end of the transfer pipe 1 is fixedly connected to a mixing tank 2 that can mix raw materials. The inner wall of the transfer pipe 1 is rotatably connected to a screw conveyor 3 that can drive the raw materials to move when rotating, facilitating feeding. The lower end of the transfer pipe 1 is provided with a mounting plate 5. The inner walls of the mixing tank 2 are all rotatably connected to a plurality of rotating shafts 9. The rod bodies of the rotating shafts 9 are all fixedly connected to a plurality of stirring fan blades 10 that can stir and mix the raw materials inside the mixing tank 2 when rotating. The upper ends of the plurality of rotating shafts 9 are all fixedly connected to secondary gears 11. The upper surface of the mixing tank 2 is rotatably connected to a rotating rod 12. The rod body of the rotating rod 12 is fixedly connected to a main gear 13. The main gears 13 are all meshed with the plurality of secondary gears 11. When the main gear 13 rotates, it can drive the plurality of secondary gears 11 to rotate, facilitating the rotating shaft 9 to drive the stirring fan blade 10 to rotate. The upper end of the mixing tank 2 is fixedly connected to a fixing plate 14. The upper end of the fixing plate 14 is fixedly connected to a second motor 15. The output end of the second motor 15 is fixedly connected to the rotating rod 12. One side of the transfer pipe 1 is provided with a transmission assembly;

[0021] Specifically, referring to Figure 1 , the transmission assembly includes a synchronous pulley 4, a first motor 6, and a synchronous belt 7. The upper surface of the mounting plate 5 is fixedly connected to the first motor 6. The output end of the first motor 6 and one side of the screw conveyor 3 are both fixedly connected to the synchronous pulley 4. The outer walls of the two synchronous pulleys 4 are both meshed with the synchronous belt 7. The first motor 6 can drive the synchronous pulley 4 on one side to rotate. Under the action of the synchronous belt 7, the two synchronous pulleys 4 can rotate synchronously through the first motor 6, thereby driving the screw conveyor 3 inside the transfer pipe 1 to rotate.

[0022] Referring to Figure 1 , the upper ends of the mounting plate 5 are all fixedly connected to a plurality of support frames 8 that can support the transfer pipe 1. The lower surface of the transfer pipe 1 is fixedly connected to the plurality of support frames 8.

[0023] Referring to Figure 3 , the inner wall of the mixing tank 2 is fixedly connected to a triangular rod 16 that can support the lower ends of the plurality of rotating shafts 9. The lower ends of the plurality of rotating shafts 9 are all rotatably connected to the triangular rod 16.

[0024] Referring to Figure 4 , one outer wall of the mixing tank 2 is fixedly connected to a feed hopper 17 to facilitate pouring raw materials into the interior of the mixing tank 2.

[0025] The implementation principle of a feeding device for an injection molding machine in an embodiment of the present application is as follows: During use, raw materials are poured into the interior of the mixing tank 2 through the feed hopper 17. The second motor 15 drives the rotating rod 12 to rotate. The rotation of the rotating rod 12 causes the main gear 13 to rotate. At the same time, the main gear 13 meshes with multiple sub-gears 11, thereby driving multiple rotating shafts 9 to rotate through the sub-gears 11. The rotating shafts 9 can mix the raw materials inside the mixing tank 2 through the stirring blades 10 on the outer wall. Then, the mixed raw materials fall into the interior of the transfer pipe 1. The first motor 6 drives the synchronous pulley 4 to rotate. Under the action of the synchronous belt 7, the two synchronous pulleys 4 can rotate synchronously through the first motor 6, thereby driving the auger 3 inside the transfer pipe 1 to rotate, facilitating the transfer of the raw materials inside the transfer pipe 1. The raw materials inside the transfer pipe 1 can be discharged through the discharge hopper at the lower end of the transfer pipe 1.
