Weight-losing type minim scale micro material weighing device

Abstract

The invention relates to a load weighting device for feeding materials, in particular to a microscale load weighting device for feeding materials of a weight-loss type microbalance. A weighting hopper is vertically mounted at one lateral side of a mounting lateral plate, a weighting sensor is arranged on a lateral wall of the back of the mounting lateral plate which is equipped with the weighting hopper, the bottom end of the weighting hopper is equipped with a discharge hole, the discharge hole extends to a groove of feeding materials which is arranged below the weighting hopper, and the tail portion of the groove of feeding material is equipped with an electromagnet. The invention is characterized in that a mounting clamp plate is disposed at the lateral side of the weighting hopper, the electromagnet is connected with the mounting lateral plate which is arranged on the weighting hopper, the wall side of the mounting lateral plate is equipped with a bending plate, and the mounting clamp plate is equipped with a vibration absorber. The load weighting device for feeding materials has the advantages of decreasing vibration, reducing the impact of the device of materials and feeding materials to the load weighting device, adding the accuracy of measuring, and then, can be completely used to weight feeding materials of graininess material, the weight of which is lower than 50 grams. Further, the load weighting device for feeding materials is accurate in weighting and fine in vibration isolation effect, and the load weighting sensor has little interruption.

Description

technical field [0001] The invention relates to a feeding material weighing device, in particular to a micro-feeding weighing device in a weight-reducing micro scale. Background technique [0002] In the prior art, the feeding and weighing device adopts a scale hopper to be installed on the sensor, and an electromagnet and a feed trough are installed at the lower end of the scale hopper, and the electromagnet is directly installed on the electromagnet mounting frame on the scale hopper, and the feed trough It is connected with the scale bucket through a spring plate. [0003] This structure has obvious limitations. The vibration of the vibrating trough driven by the electromagnet will generate a large vibration force. Only by relying on the vibration isolation of the scale bucket can the load cell be protected from the impact. The heavier the scale bucket, the better the vibration isolation effect. . When used on weighing and packaging equipment weighing more than 500 gram...

AI Technical Summary

Problems solved by technology

However, for weighing and packaging equipment below 50 grams, due to the small scale and light weight of the scale bucket, the scale bucket cannot play the role of vibration isolation, and the load cell is greatly affected by the vibration of the electromagnet, and the accuracy cannot be guaranteed, so it cannot be used.

Therefore, this kind of device can only be used on weighing and packaging equipment above 500 grams, and cannot be used on weighing and packaging equipment below 50 grams, which has certain limitations in use.
