[0027] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0028] Example

[0029] like Figure 1-3 As shown, an automatic loading device proposed by the utility model comprises a base 1, a plurality of columns 2 and a support frame 10 are fixedly installed on the top of the base 1, a frame plate 3 is fixedly installed on the top of the above-mentioned columns 2, a hopper 4 is rotatably installed on the frame plate 3, the bottom end of the hopper 4 passes through a circular opening cut on the frame plate 3 and extends to the bottom thereof, a bracket 7 is fixedly installed on the frame plate 3, a motor 6 is fixedly installed on the bracket 7, a circular gear 8 is fixedly installed on the output end of the motor 6, an annular gear ring 5 is fixedly installed on the outer wall of the above-mentioned hopper 4, the annular gear ring 5 is meshedly connected with the circular gear 8 to ensure that the motor 6 can drive the hopper 4 to rotate; the top of the above-mentioned support frame 10 is fixed A feed box 9 is installed, and a connecting seat 91 is fixedly installed on the top of the feed box 9. The bottom end of the hopper 4 is inserted into the groove on the top of the connecting seat 91 and is rotatably connected thereto, so that the hopper 4 in a rotating state can be stably docked with the feed box 9, ensuring that the powder in the hopper 4 can be transported to the inside of the feed box 9; a number of groups of guide structures are fixedly installed on the inner side wall of the feed box 9, each group of guide structures consists of two symmetrically arranged guide plates 94, and a notch is reserved at one end of the two guide plates 94 close to each other, so that the powder in the feed box 9 can be centrally processed, and the inclined guide plates 94 are conducive to the self-sliding of the powder, reducing the probability of the powder adhering to the inner wall of the feed box 9.

[0030] Furthermore, a curved cover 42 is fixedly installed on the inner bottom of the feed hopper 4. During the process of pouring a large amount of powder into the hopper 4, the curved cover 42 can serve as an impact-bearing structure to protect the discharge cover 92 inside the hopper 4; a dustproof net 41 is fixedly installed on the inner top of the feed hopper 4 by bolts. During the process of the hopper 4 rotating to discharge materials, dust formed by the powder can be prevented from floating out of the hopper 4, thereby reducing the waste of powder materials.

[0031] Secondly, a lower material cover 92 is fixedly installed in the groove on the top of the connecting seat 91. The lower material cover 92 is inserted into the hopper 4 and rotatably connected thereto, which can enhance the stability of the connection between the hopper 4 and the feed box 9. In addition, a plurality of feed ports are opened on the wall panel of the lower material cover 92 to ensure that the powder in the hopper 4 can enter the lower material cover 92 and then be transported to the feed box 9.

[0032] Furthermore, annular grooves are bored at the bottom of the annular gear ring 5 and the top of the frame plate 3, the two annular grooves are symmetrically arranged at the upper and lower parts, and a plurality of steel balls 31 are placed in the two annular grooves. During the rotation of the hopper 4, the friction between the annular gear ring 5 and the frame plate 3 can be reduced by the steel balls 31, thereby effectively improving the rotation efficiency of the hopper 4; a plurality of limit blocks 43 are fixed on the outer wall of the hopper 4 by bolts, and the limit blocks 43 are all arranged below the frame plate 3. At this time, the frame plate 3 is arranged at a position between the limit blocks 43 and the annular gear ring 5, which can prevent the hopper 4 from moving in the vertical direction, thereby improving the stability of the hopper 4 during rotation.

[0033] In this embodiment, a large amount of powder is first temporarily stored by the hopper 4 to provide a sufficient amount of powder material for the subsequent loading operation; in the loading stage, the hopper 4 is driven to rotate by the motor 6. During the rotation of the hopper 4, the lower cover 92 rotates relatively on the inner side of the outlet of the hopper 4. At this time, the powder material enters the lower cover 92 from the feed port cut on the lower cover 92, and then is discharged into the feed box 9. Since the lower cover 92 and the hopper 4 maintain a relative rotation state, the feed port can be prevented from being blocked, thereby improving the anti-blocking performance of the charging device; when the powder material enters After entering the feed box 9, the powder slides along the guide plate 94 to the opening reserved in the middle of the guide structure. At this time, the guide structure composed of the two guide plates 94 can concentrate the powder, speed up the sliding speed of the powder, and avoid a large amount of powder adhering to the inner wall of the feed box 9; the present application solves the problem that the powder material is easy to agglomerate inside the feed box 9 and a large amount of accumulated powder is easy to agglomerate at the outlet end of the hopper 4. During the loading operation, there is no need to clear the loading device, which avoids interruption during powder transportation and effectively improves the efficiency of the loading operation.

[0034] The above-mentioned specific embodiments are only several optional embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
