[0025] The specific embodiments are given below.

[0026] As Figures 1-3As shown, a feeding mechanism for injection molding machine, including feeding machine body 1, the middle part of the feeding machine body 1 is installed with storage box 11, the outer wall of the storage box 11 is fixedly connected with speed reducer motor 12, the output end of the speed reducer motor 12 is fixedly connected with half gear 13, the inner wall of the storage box 11 is slidably connected with first push plate 14, and the middle part of the first push plate 14 is meshed with half gear 13, the top of the storage box 11 is fixedly connected with frame 16, the inner wall of the first push plate 14 is fixedly connected with first elastic rope 15, and the other end of the first elastic rope 15 is fixedly connected on the middle part of the frame 16, when working, the worker needs to install the feeding machine body 1 in the designated position, align the output end of the feeding machine body 1 with the hopper position of the injection molding machine, then transfer the material to be transported to the inside of the storage box 11, start the feeding machine body 1 switch, continuously transport the material, when the storage box 11 is used for a long time and the material accumulated inside gradually decreases, the worker can start the speed reducer motor 12 switch, the output end of the speed reducer motor 12 drives the half gear 13 to rotate, the first push plate 14 meshed with the half gear 13 gradually moves to the feeding port position, and the material accumulated at the bottom of the storage box 11 is pushed to the position close to the feeding port, at the same time, the middle part of the first elastic rope 15 is elongated and generates a reaction force during the movement of the first push plate 14, when the teeth of the middle part of the half gear 13 and the first push plate 14 are separated, the first push plate 14 can be quickly pulled back to the original position under the action of the first elastic rope 15, and the above steps are repeated, the reciprocating first push plate 14 is arranged to push the material accumulated on the side wall of the storage box 11 together and discharge along the feeding port position, reduce the amount of material accumulated in the storage box 11, and improve the flowability of the material in the storage box 11.

[0027] As Figure 1 、 2As shown in , 4 and 5, the torsion spring in the middle of the first push plate 14 is connected to two groups of rotating rods 2; the top of the rotating rod 2 is fixedly connected to a first top piece 21; the middle of the rotating rod 2 is fixedly connected to a second push plate 22; the middle of the frame 16 is fixedly connected to a first connecting rod 23; the end of the first connecting rod 23 is threadedly connected to a screw 24; the end of the screw 24 is fixedly connected to a second top piece 25, and the second top piece 25 is conically set; the second top piece 25 and the two groups of first top pieces 21 are set on the same horizontal plane; when working, by arranging two groups of rotating second push plates 22 in the middle of the first push plate 14, when the first push plate 14 moves, the fixed second top piece 25 will gradually approach the position of the two groups of first top pieces 21, and then the conical The chute 5 will continue to push the two groups of first top pieces 21, causing the rotating rod 2 to rotate as a whole, and expand the two groups of second push plates 22, so that the expanded second push plates 22 can push the materials in the middle and collect them together. The screw 24 can be adjusted by rotating the second top piece 25 and expanding the second push plates 22. This step, combined with the setting of two groups of expanded second push plates 22, can further stack the materials together, thereby improving the fluidity of the materials inside the storage box 11. The two groups of rotating rods 2 set with torsion springs can reset the first top piece 21 and the second top piece 25 when they are separated. At the same time, the screw 24 can enhance the flexibility of the two groups of second push plates 22 when they are working.

[0028] like Figure 5 As shown, the inner wall of the second push plate 22 is provided with a storage groove 3; the inner wall of the storage groove 3 is fixedly connected to the second elastic rope 31; the end of the second elastic rope 31 is fixedly connected to the shielding cloth 32, and the other end of the shielding cloth 32 is fixedly connected to the middle part of the first push plate 14; when working, by opening the storage groove 3 on the inner wall of the second push plate 22, when the second push plate 22 is unfolded, the end of the shielding cloth 32 is fixed to the middle part of the first push plate 14, and the middle parts of the two sets of second elastic ropes 31 will be stretched, and the shielding cloth 32 will be stretched. The cloth 32 will unfold the inner wall of the second push plate 22 for shielding. At the same time, when the second push plate 22 is reset, and under the action of the two sets of second elastic ropes 31, the shielding cloth 32 can be stored again. This step is combined with the setting of the shielding cloth 32 to reduce the problem that part of the material is transferred to the inner wall of the second push plate 22 when the second push plate 22 is unfolded, making it difficult for the end of the unfolded second push plate 22 to fit together with the middle of the first push plate 14, thereby improving the stability of the second push plate 22 in subsequent use.

[0029] like Figure 4As shown, the first connecting rod 23 top is fixed with a spring column 4; the spring column 4 output end top is fixed with an elastic plate 41; during operation, by setting the spring column 4 on the top of the first connecting rod 23, when the external material is poured into the storage box 11, part of the material will be blocked by the elastic plate 41 and be positionally transferred, at the same time, the vibration force generated during the operation of the storage box 11 can make the spring column 4 output end move up and down and vibrate and clean the dust in the middle of the elastic plate 41, which can reduce the adsorption of part of the impurities or granular material in the groove of the screw 24, so that the subsequent staff can rotate the second top piece 25 without jamming, and the spring column 4 can reduce the period of attachment of more impurities in the middle of the elastic plate 41.

[0031] As shown in the figure, Figure 3 The first push plate 14 is fixed with a gasket 6 at the end, and the gasket 6 inner wall is in contact with the first elastic rope 15; during operation, the gasket 6 can make the first push plate 14 contact the inner wall of the frame 16 first when it is quickly reset, which can reduce the damage to the end of the first push plate 14 caused by impact, and the gasket 6 in contact with the first elastic rope 15 can improve the neatness of the middle of the first elastic rope 15.

[0032] As shown in the figure, Figure 5 The first top piece 21 is fixed with a friction piece 7 in the middle; during operation, by setting the friction piece 7 in the middle of the first top piece 21, the second top piece 25 will first contact the first top piece 21 when it is close to the first top piece 21, which can increase the friction between the first top piece 21 and the second top piece 25 and reduce the problem of slipping between them.
