Three material door blanking device

Abstract

The invention discloses a discharging device with three doors. The discharging device with the three doors comprises a seat, a first air cylinder, an electric push rod, a first connecting rod, a second connecting rod, a third connecting rod, a hopper, a first door, a second door, a third door, a first door spindle, a second door spindle and a third door spindle, wherein a first discharging opening is formed in the bottom of the hopper; a second discharging opening is formed in a side wall of the hopper; one end of the first connecting rod is fixedly connected with the third door spindle; the other end of the first connecting rod is hinged to the second connecting rod; the other end of the second connecting rod is hinged to the third connecting rod; one end of the third connecting rod is fixedly connected with the second door spindle; the other end of the third connecting rod is hinged to the electric push rod; a spindle of the first air cylinder drives the first door spindle to rotate so that the first discharging opening is opened or closed; and the electric push rod drives the third door so that the second discharging opening is opened or closed. The discharging device with the three doors has the advantages that the sizes of the first discharging opening and the second discharging opening are controlled to control flow velocity and flow of materials, so that weighing speed and precision are improved; and the discharging device with the three doors is suitable for different range sections and is suitable for weighing different materials.

Description

technical field

[0001] The invention relates to a blanking and feeding device, in particular to a three-gate blanking device. Background technique

[0002] After the material door of the free-fall feeding device is opened, the material is added to the meter by its own weight, wherein the closing and opening of the material door is controlled by a cylinder. When the cylinder controls the material door to open, the hopper adds material to the meter, and when the material in the meter is added to the predetermined weight range, the cylinder controls the material door to close. Since the stroke of the cylinder is fixed, when the initial position of the cylinder is not adjusted, the opening of the material door remains unchanged each time, and the material is under the action of gravity. If the initial position of the cylinder is not suitable, the weight of the material may fall into the meter instantly. If the measuring range is exceeded, or because the opening is too small, it...
