DETAILED DESCRIPTION

[0023] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0024] like Figure 1-Figure 4 As shown, the embodiment of the utility model provides an injection molding machine feeding structure, comprising:

[0025] Base 1, two No. 1 electric push rods 2 and two No. 2 electric push rods 3 are fixedly arranged on the surface of the base 1 through a bracket, a material loading and unloading component, the material loading and unloading component includes a bearing plate 4 arranged above the base 1, two T-shaped slide grooves 5 are arranged on the bottom surface of the bearing plate 4, and T-shaped slide plates 6 are slidably connected in the two T-shaped slide grooves 5. The output ends of the two No. 1 electric push rods 2 are hinged to the bottom surface of the bearing plate 4, and the output ends of the two No. 2 electric push rods 3 are hinged to the bottom surface of the T-shaped slide plate 6. A material unloading box 7 is fixedly connected to the upper surface of the bearing plate 4. The two No. 1 electric push rods 2 and the two No. 2 electric push rods 3 are hinged to the bottom surface of the T-shaped slide plate 6. The No. 1 electric push rod 2 is respectively arranged in parallel with the two No. 2 electric push rods 3, so that the bearing plate 4 is always in a stable state. The two No. 1 electric push rods 2 and the two No. 2 electric push rods 3 are parallel to each other to provide a sufficiently stable support for the bearing plate 4. The two No. 1 electric push rods 2 and the two No. 2 electric push rods 3 cooperate with each other to make the bearing plate 4 and the base 1 in a parallel state when not in use. When the two are in use, the movement frequency is also the same, and they can run synchronously to drive the bearing plate 4 to rise steadily for loading;

[0026] A cleaning assembly is arranged above the base 1, and the cleaning assembly includes a sleeve shell 8 fixedly connected to the side wall of the dump box 7, the inner wall of the sleeve shell 8 is rotatably connected to a rotating shaft 9 through a bearing, and the rotating shaft 9 is fixedly connected to one end of the dump box 7 with a blowing fan blade 10, and a spring spring 11 is fixedly connected between the circumferential side wall of the rotating shaft 9 and the circumferential inner wall of the sleeve shell 8, and a rope 12 is wound around the rotating shaft 9, a fixing plate 13 is fixedly connected to the upper surface of the base 1, and a wire drawing roller 14 is fixedly connected to the side wall of the fixing plate 13, and the other end of the rope 12 is fixed to the surface of the wire drawing roller 14, a through hole 15 is provided on the bottom surface of the sleeve shell 8, and the rope 12 is located in the through hole 15, and the side walls on both sides of the dump box 7 are provided with through holes. Slot 16, two through slots 16 are each provided with a protective mesh cover 17, the casing 8 is fixed outside the through slot 16 on one side of the dump box 7, through the through slot 16, the airflow generated by the blowing fan blade 10 can enter the dump box 7 and flow between the raw materials, and the dust and impurities on the surface of the raw materials are taken away by the flowing airflow, and discharged through the through slot 16 on the other side. The pores of the protective mesh cover 17 are very small and will not cause leakage of the raw materials, and will not block the removal of dust and impurities. The side wall of the casing 8 is equidistantly provided with a plurality of air inlets 18, and a filter screen is provided in the plurality of air inlets 18 for the flow of airflow, while ensuring that the airflow blown into the dump box 7 through the blowing fan blade 10 is clean enough.

[0027] The detailed working process of the utility model is as follows:

[0028] When in use, first pour the raw materials into the dumping box 7, then start the two No. 1 electric push rods 2 and the two No. 2 electric push rods 3 at the same time, and through the synchronous movement of the four, drive the carrying plate 4 to move upward, and then drive the dumping box 7 to move upward. When the edge of the dumping box 7 moves to the feeding port where the material can be loaded, the two No. 1 electric push rods 2 stop, and the two No. 2 electric push rods 3 continue to move, and then the two No. 2 electric push rods 3 continue to move upward, which will drive the two T-shaped slide plates 6 to slide in the two T-shaped chutes 5, and the dumping box 7 will also tilt, so that when the dumping box 7 is loaded, a dumping action can be attached to ensure that the raw materials in the dumping box 7 can be completely poured in. When the raw materials in the dumping box 7 are completely poured in, the output ends of the two No. 1 electric push rods 2 and the two No. 2 electric push rods 3 are returned to facilitate the next loading;

[0029] During the loading process, the supporting plate 4 moves upward, driving the dump box 7 to move upward, and then driving the casing 8 to move upward, so that the wire pulling roller 14 gives the rope 12 a pulling force, so that the rope wrapped around the rotating shaft 9 is continuously pulled out. When the rope 12 is pulled out, the rotating shaft 9 will rotate under the action of friction, and then drive the fan blades 10 to rotate, generating a certain amount of flowing airflow, and the flowing airflow is used to take away the dust and impurities on the surface of the raw material, so as to achieve a simple cleaning treatment of the surface of the raw material inside the dump box. When the supporting plate 4 drives the dump box 7 and the casing 8 to reset, under the action of the clockwork spring 11, the rotating shaft 9 gradually rewinds the pulled ropes 12, which is similar to the working principle of the steel tape measure. In this way, the work is repeated all the time and is carried out synchronously with the loading operation, which is more efficient and convenient.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
