Belt weigher

Abstract

The invention discloses a belt weigher which comprises a base, a support and a conveying belt. The support is mounted on the base, the support is provided with a laser sensor, and a motor is mounted at the tail position of the support. A plurality of supporting rollers are mounted on the base, and the supporting rollers are provided with the conveying belt. A plurality of sensing devices are mounted on the conveying belt, and the conveying belt is provided with a weight meter. A hopper is mounted at the upper end of the conveying belt, and the hopper is not in contact with the conveying belt. A control panel is mounted on the base, a processing chip is arranged in the control panel, and the processing chip is connected with the motor, the weight meter and the laser sensor through wires. Through the above mode, according to the belt weigher, the laser sensor which is mounted on the support and the sensing devices which are mounted on the belt are matched, so that the metering speed of the belt is calculated, the condition that inaccurate speed metering can likely happen in the prior art is reduced, and weighing accuracy is higher.

Description

technical field [0001] The invention relates to the field of measurement, in particular to a belt scale. Background technique [0002] Belt scales are widely used in industrial production to weigh materials. In the process of conveying materials, belt scales often need to determine the amount of feed per unit time, so as to control the amount of feed in process production. There are two main types of speed measuring devices commonly used in belt scales in production, one is "contact type", which installs a speed measuring sensor and directly measures speed through the sensor; the other is "non-contact type", that is, installs Hall elements or reducer gears Speed ​​measurement, the common disadvantages of the two speed measurement devices are: because the installation parts are all on site, and the site environment is relatively harsh, there are many human and non-human factors, the speed measurement part is often damaged, such as gear jumping; It will cause inaccurate speed...

If the on-site management is not in place, the batching system may not operate normally
