Problems solved by technology

When the environment temperature and humidity change or the material sticks on the belt and the tare value changes, the system does not know the change of the actual tare weight, which leads to errors in the measurement during the actual production process. Before the weight value is re-calibrated, the measurement accuracy of the belt scale is difficult to ensure good stability

Embodiment 1

[0018] Embodiment one, as attached figure 2 As shown, the present invention provides an electronic belt scale with an online tare function, comprising a belt scale feed area 1, a driven drum 2, a driving drum 7, a tare detection scale platform 4, a material weighing scale platform 6 and a discharge In zone 8, the tare detection weighing platform 4 and the material weighing weighing platform 6 are in the same plane, and the driving roller 7 is driven by the drive motor 9 through the sprocket pair to drive the conveyor belt 3 to move. An isolation belt conveyor 16 is set below the feed area 1, and the isolation belt conveyor 16 includes a forward roller 10 and a turning roller 11, and the forward roller 10 and the turning roller 11 are connected through a belt, and the forward roller 10 and the turning roller 11 are connected by a belt. The driven roller 2 is connected to the roller 10 .

[0019] Open up the installation space for the online tare weighing platform, see attache...

Embodiment 2

[0020] Embodiment two, as attached image 3 , in the feed area 1, there are forward rollers 10 and folding rollers 11 (with antistatic and anti-adhesive coatings), and the belt runs along the image 3 The direction shown in , is wound back along the "S" shape of the folding roller, so as to open up the installation space of the online tare weighing platform under the unloading area, realize the online detection function of tare weight, and maintain the traditional belt scale. The way of feeding and discharging remains unchanged.

[0021] as attached figure 1 As shown, the driving motor 9 drives the driving drum to rotate through the sprocket pair, thereby driving the belt to move. The front-end equipment feeds from the feeding area at the tail of the scale. The material reaches the top of the weighing platform after being folded towards the roller. The weighing platform detects the gross weight of the material, and the gross weight minus the weight below the feeding area Th...

Abstract

The invention discloses a belt weigher. The belt weigher comprises a feeding area, a driven roller, a driving roller, a material weighing platform, a conveying belt, a discharging area, a driving motor and a frame, wherein the driving motor is in driving connection with the driving roller; the driving roller is connected with the driven roller through the conveying belt; a tare weight detection weighing platform is arranged at a feed end of the material weighing platform; an isolated belt conveyer is arranged below the feeding area, and comprises a forward direction roller and a bending direction roller; the forward direction roller is connected with the bending direction roller through a belt; and the forward direction roller is also connected with the driven roller. An S-shaped back-winding type belt mounting mode is adopted, and the tare weight detection weighing platform is arranged right below the feeding area, an online peeling function is achieved, and a mode that feeding is performed on the tail part of the conventional belt weigher and discharging is performed on the head part of the conventional belt weigher is kept unchanged. The belt weigher has the characteristics of accurate weighing and stability.

Description

technical field [0001] The invention relates to a belt scale, in particular to a belt scale with an online tare detection function. Background technique [0002] The belt scales currently used in the market generally only have a weighing platform for detecting gross weight (including tare weight and net material weight). The belt scale measures a tare value in a non-production no-load state, and then the tare weight The value should be used in the calculation of meter accumulation during the production process. When the environment temperature and humidity change or the material sticks on the belt and the tare value changes, the system does not know the change of the actual tare weight, which leads to errors in the measurement during the actual production process. Before the weight value is re-calibrated, the measurement accuracy of the belt scale is difficult to ensure good stability. Contents of the invention [0003] The purpose of the present invention is to provide ...
