Description

Technical Field

[0001] The utility model relates to the technical field of spiral metering scales, in particular to a spiral metering scale with a material leakage prevention function. Background Art

[0002] Spiral metering scales are divided into single-tube single-layer and double-tube double-layer. The single-tube single-layer can complete metering and conveying at the same time. The double-tube double-layer structure completes flow stabilization and conveying on the upper layer, and metering and conveying on the lower layer. It has better flow stabilization effect and saves space. The length of the spiral feeder can be determined by actual conditions. According to the user, a double-tube structure is generally used to complete material metering, that is, a screw conveyor is required, which is used together with a spiral metering scale to complete material metering. It is mainly used for the metering of powder materials or small particles.

[0003] According to a leakage-proof metering scale disclosed on the patent website (authorization announcement number: CN213209226U), "The utility model discloses a leakage-proof metering scale, which belongs to the technical field of metering devices. It solves the problem that materials in the metering scale in the prior art are prone to wear of the sealing ring and cause leakage. The utility model includes a weighing platform, a motor, a reducer, a screw conveyor, a metering scale hopper and a metering scale lower hopper. A connector is provided between the screw conveyor and the reducer, and a sealing ring and a reducer power output shaft are provided in the connector. The screw conveyor includes a screw conveyor housing and a screw rod, and the reducer power output shaft is fixedly connected to the screw rod. A connector barrel is provided at one end of the connector, and the connector barrel is located on the side close to the screw rod. The outer diameter of the connector barrel is the same as the outer diameter of the connector, and one end of the screw rod is located in the connector barrel. The utility model can prevent or reduce the contact between the accumulated materials in the metering scale and the sealing ring, thereby eliminating or reducing the wear of the sealing ring and extending the normal working time of the metering scale without leakage."

[0004] Based on the above, the applicant believes that there are the following defects:

[0005] The anti-leakage weighing scale includes a weighing platform, a motor, a reducer, a screw conveyor, a weighing scale hopper and a weighing scale lower hopper.
