Weighing box and weighing device thereof

Abstract

The invention provides a weighing box and a weighing device thereof. The weighing box comprises a box body, a hopper, baffle plates, a quantitative weighing mechanism and a connecting frame. The hopper is arranged on the box body, and the two baffle plates are oppositely arranged in a discharge pipe at the bottom of the hopper, so that the two baffle plates can plug or open the discharge pipe; the quantitative weighing mechanism comprises a supporting plate, a weighing plate, a spring I, a lower pressing arm, a lower swing arm, a gear, a rack and a damping adjusting assembly. The weighing plate is pressed down by an object to be weighed, the gear can be driven to rotate under the action of the pressing arm and the lower swing arm, the gear can drive the rack to linearly move, and therefore after the weighing plate moves downwards by a certain distance, the rack can drive the baffle plates to block the discharge pipe, and then the quantitative weighing and discharging effect is achieved. Manual control is not needed in the whole quantitative weighing process, the discharge pipe can be automatically blocked after the weight of the weighed object reaches the preset weight, and operation is convenient.

Description

technical field [0001] The invention relates to the technical field of weighing, in particular to a weighing box and a weighing device thereof. Background technique [0002] The publication number is CN209649078U, which discloses an automatic metering distributing machine, including a distributing machine body, a weighing box, a feeding bin and a mixing bin. The top of the distributing machine body is fixedly connected with a weighing box, and the weighing box is slidingly connected with a weighing The bottom end of the weighing bin is fixedly connected with a discharge pipe, and the bottom end of the weighing bin is fixedly connected with a return spring between both sides of the discharge pipe and the inner bottom surface of the weighing box.

Problems solved by technology

[0003] The above prior art achieves quantitative feeding through the rotation of the screw feed roller, but when the weighed item reaches the preset weight, it is necessary to manually close the rotation of the screw feed roller, and then the whole process is equivalent to a semi-automatic process, which is not easy to operate
