DETAILED DESCRIPTION

[0017] In order to facilitate the understanding of those skilled in the art, the utility model will be further described below in combination with examples and drawings, and the content mentioned in the implementation manner is not a limitation on the utility model. The utility model will be described in detail below in combination with the drawings.

[0018] Please refer to Figures 1-3The specific implementation of a hardware automatic weighing device includes a rack 1, a weighing host 2 and a rotary material feeding and shaking disc 5. The weighing host 2 is arranged at the middle part of the rack 1, and the two sides of the rack 1 are respectively provided with a first material falling area 3a and a second material falling area 3b. The top weighing part of the weighing host 2 is provided with a feeding mechanism 4. The feeding mechanism 4 transports materials to the first material falling area 3a or the second material falling area 3b through forward rotation or reverse rotation. The rotary material feeding and shaking disc 5 is arranged at the rear end of the rack 1 close to the weighing host 2. The output end of the rotary material feeding and shaking disc 5 is provided with a transportation track 6. The end of the transportation track 6 away from the rotary material feeding and shaking disc 5 is arranged above the feeding mechanism 4.

[0019] The rotary material feeding and shaking disc 5 and the transportation track 6 can transport hardware one by one to the feeding mechanism 4 above the weighing host 2. The weight of the feeding mechanism 4 is removed, and the total amount of hardware materials in the feeding mechanism 4 is continuously detected. When the weight meets the error interval, the hardware materials can be transported to the first material falling area 3a through the feeding mechanism 4. Conversely, when the weight is greater than the error interval, the hardware materials can be transported to the second material falling area 3b through the feeding mechanism 4. High-precision weighing and shunting are realized, the precision of hardware weighing and packaging is improved, and the efficiency of hardware weighing and packaging is improved.

[0020] In a further scheme, as shown in Figures 2-3 The feeding mechanism 4 includes a transportation belt rack 41 and a first synchronous belt 42 arranged on the surface of the transportation belt rack 41. The first synchronous belt 42 is horizontally movably arranged between the first material falling area 3a and the second material falling area 3b. The two sides of the transportation belt rack 41 are vertically arranged side plates 43. The surface of the side plates 43 is provided with a second synchronous belt 44 which can be horizontally moved. The middle part of the second synchronous belt 44 is provided with two inwardly protruding horizontal baffles 441. The two sides of the second synchronous belt 44 can be located above the first synchronous belt 42 to form a material waiting area 8. The middle part of the first synchronous belt 42 is provided with two upwardly protruding vertical protrusions 421. The two vertical protrusions 421 respectively abut the inner side walls of the horizontal baffles 441.

[0021] When the small hardware is transported and separated, it is easy to be jammed between the embedded transport belt frame 41 and the side plate 43, so the surface of the side plate 43 is provided with a horizontally movable second synchronous belt 44, so that the hardware can be smoothly transported, and when a plurality of small hardware falls into the feeding mechanism 4, the position is easy to disperse, the middle part of the second synchronous belt 44 is provided with two inwardly protruding horizontal baffles 441, which can be located above the first synchronous belt 42 to form a material waiting area 8, so that the position of the hardware is more concentrated, and when the separated material falls, it is not easy to remain in the feeding mechanism 4, and the middle part of the first synchronous belt 42 is provided with two upwardly protruding vertical protrusions 421, which abut against the inner side wall of the horizontal baffle 441, so that the horizontal baffle 441 is touched by the first synchronous belt 42 and drives the second synchronous belt 44 to move, so that the first synchronous belt 42 drives the second synchronous belt 44 to move synchronously, which can effectively reduce the driving part for driving the second synchronous belt 44 to move, and optimizes the structure of the feeding mechanism 4.
