Description

Technical Field

[0001] The present invention relates to the technical field of metal detection equipment, and particularly relates to a high-speed online metal detection and weighing integrated machine. Background Art

[0002] In the prior art, an automatic weighing machine is generally arranged at the middle position of a section of production line. It is equipped with a conveyor belt that rotates to convey articles. The two ends of its upper surface respectively connect to the production line. The weighing principle is basically that weight sensors are installed under the conveyor belt, and the weight sensors detect the weight change of the entire conveyor belt and then transmit the weight signal to a computer. The weight sensors are basically strain-type sensors, which move downward a certain distance under gravity and emit an electrical signal.

[0003] For example, in the patent: CN201621424885.9, an online full-automatic weighing and labeling machine, its components are a most common automatic weighing machine. Conventional automatic weighing generally sets a conveying support plate at the bottom of the conveyor belt to sense the weight. In this structure, during the conveying process, the conveyor belt cannot be completely in close contact with the support plate, which is likely to cause measurement errors, especially for light-quality products such as sanitary products. If the conveyor belt is completely in close contact with the support plate, it is likely to cause excessive wear of the belt or the support plate, and the weighing equipment cannot be used for a long time.
