a weighing device comprises the weighing box.

The working principle of the invention is as follows: an article to be weighed is placed on the weighing plate 42, the article presses down the weighing plate 42, when the weighing plate 42 moves downwards, the pressing arm 44 moves downwards to press the lower swing arm 45, at the moment, the gear 46 rotates to drive the racks 47 to linearly displace, at the moment, the two racks 47 move towards the direction of mutual approach under the drive of the two gears 46, and then the two baffles 3 are driven to move towards the direction of mutual approach through the connecting frame 5, at the moment, the discharge pipe at the bottom of the hopper 2 is gradually blocked by the baffles 3, so that the discharge amount is gradually reduced, when the weight of the weighed article reaches the preset weight, the discharge pipe at the bottom of the hopper 2 is completely sealed by the baffles 3, so that the quantitative discharging effect is realized, and the limit toothed plate 421 descends along with the descending process of the weighing plate 42, because the clamping plates on the limit toothed plate 421 are arranged obliquely upwards, and then can push away ejector pin 422 when cardboard and ejector pin 422 contact, so weighing plate 42 can freely descend, and when the goods takes off from weighing plate 42, spring I43 can jack up weighing plate 42, but ejector pin 422 can block the cardboard in spacing toothed plate 421 side, and then avoid weighing plate 42 directly kick-back, so baffle 3 still can continue to plug up the discharging pipe of 2 bottoms of hopper, avoid weighing the article that does not weigh after the completion at last time and fall down, take out ejector pin 422 when needing to weigh article once more, make ejector pin 422 break away from spacing toothed plate 421, so rebound that weighing plate 42 can be free, and then return to initial position. The blanking amount of the process object weighed by the quantitative blanking is gradually reduced, and the weighing weight can be accurately controlled.

The weight of quantitative blanking is adjusted through the damping adjusting assembly 48, specifically, the bidirectional screw 481 is rotated, then the two clamping rings 482 are far away from the gear 46 or are close to the gear 46, when the clamping rings 482 are far away from the gear 46, the rotating friction force of the gear 46 is reduced, further, the rotating damping of the gear 46 is reduced, then, when the weight of an article placed on the weighing plate 42 is light, the gear 46 can be directly driven to rotate to reach the discharge pipe at the bottom of the plugging hopper 2, and when the weight of the article placed on the weighing plate 42 is heavy, the gear 46 can be driven to rotate, and further, the weight of quantitative blanking is adjusted.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
