Continuous dynamic weighing chain belt type feeding machine

Abstract

The invention discloses a continuous dynamic weighing chain belt type feeding machine. The continuous dynamic weighing chain belt type feeding machine is composed of a driving device, a drive sprocket group, a tension sprocket group, a combined chain belt, a base, a fixed material guide groove, a weight body, a weighing sensor, a rotating speed sensor and a weight body guide post, wherein the driving device drives the combined chain belt to do circulatory motion through the drive sprocket group; the tension sprocket group is used for tensioning the combined chain belt; the weight body is composed of a weight platform, a weighing sprocket group, a hanging post and a weight groove; the weighing sprocket group is engaged with a sleeve roller chain at two sides of the combined chain belt at the weighing section so as to support the combined chain belt at the weighing section; and the weight groove is arranged on the weight platform through the hanging post. The weight body is connected to the base through the weighing sensor; the weight groove and the fixed material guide groove compose a material conveying groove; and the weight body guide post is used for vertically guiding the weight body. The weighing feeding machine has a compact structure, can prevent a conveyor belt from deviating and slipping, works reliably and has high weighing precision, good accuracy and wide application foreground.

Description

technical field [0001] The invention relates to a weighing chain-belt feeder, in particular to a continuous dynamic weighing chain-belt feeder suitable for reloading and feeding of bulk materials. Background technique [0002] Continuous feeders such as belt feeders and chain belt feeders are widely used in bulk material transportation systems due to their large feeding volume and continuous and uniform feeding. Weighing feeder can be developed by adding weighing device on the basis of original feeder. However, the principle of the weighing device of the current feeder with weighing function is to simply and directly adopt the weighing principle of the belt conveyor, that is, to install a weighing sensor under the supporting roller of the conveyor belt, or to support it with a weighing roller. For the conveyor belt, install the weighing rollers on the scale frame, and then install the load cell under the scale frame to sense the weight of the continuously passing materials....

AI Technical Summary

Problems solved by technology

[0005] Furthermore, the belt feeder has the problems of slipping, belt deviation and tearing, while the first belt feeder has different elongation between the first belt and the conveying belt, resulting in slippage between the transmission belt and the first belt and tension issues

Due to the inherent problems of the conveyor belt, the tape or a belt feeder has disadvantages such as large maintenance and inconvenient maintenance in use, which have affected its actual production and application.

If a weighing feeder is developed on the basis of an adhesive tape and a belt feeder, it will inevitably carry the defects of the original feeder. In addition to the complicated link of the weighing device, it will cause weighing tape and a belt feeder. The feeder creates more problems in use
