Embodiment Construction
[0029] An electronic belt scale proposed by the present invention has a belt, at least including a belt of a material transmission part and a belt of a return part; a plurality of support rollers are arranged at the lower part of the belt, wherein two support brackets arranged at the lower part of the belt of the material transmission part A metering section is arranged between the rollers, and a belt hardness detection mechanism is provided at the lower part of the belt at the return part, and the belt hardness detection mechanism at least includes a supporting roller supporting the belt at the return part. A load sensor; a meter connected to the metering section and the load sensor respectively. By installing a belt hardness detection mechanism on the existing electronic belt scale, the detected change in belt hardness is transmitted to the measuring instrument, and the measuring instrument performs real-time compensation for the weighing result at any time according to the d...

The invention relates to an electronic belt scale and a metering precision compensating method for the electronic belt scale. The electronic belt scale is provided with a belt; the belt at least comprises a material transportation part belt and a return part belt; a plurality of support rollers are arranged at the lower part of the belt; and a metering section is arranged between the two support rollers at the lower part of the material transportation part belt. The electronic belt scale is characterized in that the lower part of the return part belt is provided with a belt hardness detectingmechanism; the belt hardness detecting mechanism at least comprises a support wheel and a metering instrument, wherein support wheel is used for supporting the return part belt; the lower part of thesupport wheel is provided with a load sensor; and the metering instrument is respectively connected with the metering section and the load sensor. By measuring the temperature change of the belt and the hardness change of the belt at any time and carrying out real-time compensation on the precision offset generated by the change of the temperature and hardness of the belt at any time, the invention can effectively improve the metering precision and stability of the electronic belt scale.
Description
technical field [0001] The invention relates to an electronic belt scale, in particular to an electronic belt scale capable of real-time compensation of measurement accuracy according to changes in belt hardness, and a method for compensating measurement accuracy of the electronic belt scale according to the detected belt hardness. Background technique [0002] The electronic belt scale is used in the production line to measure solid and broken materials. figure 1 It is a structural schematic diagram of a known electronic belt scale. Such as figure 1 As shown, the working principle of the electronic belt scale 1 is: the material falls from the hopper to the belt 3, driven by the transmission wheel, the belt 3 advances in the direction shown by the arrow 2. Due to the forward movement of the belt 3, the materials on the belt 3 are driven forward. A plurality of supporting rollers 11, 12, 13, 14 etc. are arranged between the two transmission wheels to ensure the smooth oper...
