Problems solved by technology

[0002] Constant-volume metering plate is a commonly used weighing device, which has the characteristics of simple structure, convenient operation, high weighing efficiency and high weighing accuracy, so it is widely used in the weighing of powders, tiny particles, etc., but due to There are tiny gaps that cannot be eliminated between the metering plate and the upper and lower plates, so during the weighing process, powder or tiny particles will enter these tiny gaps with the linear motion of the metering plate, and accumulate more and more, causing the metering plate to It gets tighter and tighter and eventually gets stuck and can't move
In order to prevent the metering board from being stuck, it is necessary to clean the metering board at regular intervals, which seriously affects the weighing efficiency
In particular, explosive agents weighed by constant-volume metering plates often have high friction sensitivity, and there is a danger of being ignited or detonated during the weighing process. Once ignited or detonated, the consequences are disastrous

Embodiment 1

[0027] This embodiment provides a kind of anti-floating drug device for constant volume metering plate, such as figure 1 As shown, including the lower plate 1 of the metering plate, the upper plate 2 of the metering plate and the metering plate 3, a side surface extending along the moving direction of the metering plate is arranged between the upper plate surface of the lower plate 1 of the metering plate and the lower plate surface of the plate 2 of the metering plate The guide member, the lower plate 1 of the metering plate, the upper plate 2 of the metering plate and the side guides form a chamber, and the metering plate 3 moves back and forth in the chamber under the drive of external force; the metering plate 3 is provided with metering holes 4. An installation groove is provided on the upper surface of the lower plate 1 of the metering plate, and an elastic block 5 and a compression block 6 are arranged in the installation groove sequentially from bottom to top, and the c...

Embodiment 2

[0030] Further improvement on the basis of Embodiment 1, the elastic limiter 8 adopts a spring; the inner wall of the port facing the metering plate 3 on the leakage hole is provided with an annular limiter groove 9 along the circumference, and the inner diameter of the annular limiter groove 9 is larger than The inner diameter of the drug leakage hole; the upper leakage pipe 7 is provided with an annular pressure plate 10 along the circumference on the outer wall of the bottom end port of the metering plate 3, and the outer diameter of the annular pressure plate 10 is greater than the inner diameter of the drug leakage hole and smaller than the inner diameter of the annular limit groove 9 ; The spring is set on the upper leakage pipe 7, and the axial ends are clamped between the annular pressure plate 10 and the bottom surface of the annular limiting groove 9, respectively. The annular pressing plate 10 is integrally formed by flanging at the port of the upper leakage pipe 7 ....

Embodiment 3

[0032] Further improvement on the basis of embodiment 2, taking the installation substrate as the center reference, the metering plate lower plate 1 is installed on the installation substrate 11 through the positioning pins, the metering plate 2 is installed on the metering plate lower plate 1 through the positioning pins, and The groove of the plate 2 on the metering plate and the groove of the lower plate 1 of the metering plate form a rectangular groove structure. The metering plate 3 is placed in the rectangular groove and can move back and forth in the rectangular groove; The connected medicine funnel 12. The plate 2 on the metering plate is provided with a feed hopper 13, and the output end of the feed hopper 13 communicates with the top port of the upper leakage material pipe 7; The switch 14 that communicates between the leakage pipe 7.

Abstract

The invention discloses an anti-floating-powder device for a constant-volume meter plate. Meter plate upper and lower plates and side guide plates form a chamber, and the meter plate can move back andforth in the chamber; the upper surface of the meter plate lower plate is provided with an installation groove; the installation groove is provided with an elastic block and a press block from the bottom up in sequence; the meter plate upper plate is provided with a powder leak hole; the powder leak hole is equipped with an upper material leakage pipe arranged along the same axis; the upper material leakage pipe is provided with an elastic limit member; and the elastic limit member allows the upper material leakage pipe to move up and down along the axis of the powder leak hole. During the forward and backward movement of the meter plate, the elastic block is in a compressed state, and the press block is in press contact with the lower surface of the meter plate; and under the action of the elastic limit member, the output port of the upper material leakage pipe is in press contact with the upper surface of the meter plate. The anti-floating-powder device for the constant-volume meterplate can improve weighing accuracy and efficiency of the constant-volume meter plate.
