[0014] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments (for the convenience of description and understanding, the upper part of Figure 2 is described as the upper part below). Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0015] Please refer to Figures 1-3 , the present utility model provides a technical solution: An aluminum powder flow control structure, including a fixed box 2, a screw rod 3 and a baffle 5. The fixed box 2 is fixed at the upper end of the chute 1. The inside of the fixed box 2 is communicated with the inside of the chute 1. A baffle 5 is arranged inside the fixed box 2. The size of the baffle 5 is adapted to the internal size of the chute 1. The upper end of the baffle 5 is rotatably connected to the lower end of the screw rod 3 through a bearing. The upper end of the screw rod 3 passes through the fixed box 2 and the screw rod 3 is in threaded connection with the fixed box 2. By rotating the screw rod 3, the up and down movement of the baffle 5 can be controlled, thereby adjusting the gap between the baffle 5 and the bottom of the chute 1 and controlling the feeding amount of the aluminum powder;

[0016] A fixing block 6 is arranged at the upper end of the outer side surface of the screw rod 3. A bearing ring 7 is arranged on the outer side surface of the fixing block 6. An indicating rod 9 is fixed on the outer side surface of the bearing ring 7. The arrow end of the indicating rod 9 faces the scale rod 8. The scale rod 8 is fixed at the upper end of the fixing box 2. Scales 10 are evenly distributed on the scale rod 8. The "0" position in the scales 10 is located at the upper end of the scale rod 8. When the lower surface of the baffle 5 is flush with the upper end of the inner side surface of the chute 1, the indicating rod 9 is just located at the "0" position in the scales 10. When the screw rod 3 is rotated, the descending dimension of the baffle 5 is displayed through the scales 10. Combining with the internal height dimension of the chute 1, the gap between the baffle 5 and the bottom of the chute 1 can be judged, so as to accurately control the feeding amount of the aluminum powder.

[0017] Furthermore, in order to prevent the aluminum powder from flowing out from the side surface of the baffle 5, both sides of the baffle 5 are attached to the inner side surfaces of both sides of the chute 1.

[0018] Furthermore, in order to facilitate the worker to rotate the screw rod 3, a rotating handle 4 is arranged at the upper end of the screw rod 3.

[0019] Furthermore, in order to improve the sealing performance and prevent dust and other sundries from entering the chute 1, the contact surfaces between the fixing box 2 and the chute 1 are all connected by welding.

[0020] During use: when it is necessary to adjust the feeding amount of the aluminum powder, the screw rod 3 is rotated to make the arrow of the indicating rod 9 align with the "0" position in the scales 10. At this time, the surface baffle 5 is flush with the upper end of the inner side surface of the chute 1. According to the required feeding amount to be controlled, the screw rod 3 is continuously rotated until the indicating rod 9 stops at the corresponding scale 10 position, that is, the gap between the baffle 5 and the bottom of the chute 1 is determined, so as to accurately control the feeding amount of the aluminum powder.

[0021] The utility model accurately controls the feeding amount of the aluminum powder. At the same time, the baffle 5 is arranged at the upper middle position of the chute 1, which can control the feeding amount in advance, reduce the labor intensity of workers, and facilitate the operation and use of workers.

[0022] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
