Embodiment Construction

[0027] This embodiment is used to realize the synchronous peeling belt scale of belt scale weighing synchronous peeling method such as Figure 2 to Figure 5 As shown, a group of metering rollers 4 and a loop conveyor belt 2 are installed on the frame 10 . During the loop-back operation, the conveyor belt 2 can be divided into a positive process section carrying materials and an empty return section. The positive process section is carried on the weighing roller 4, and the measuring roller 4 is carried on the load cell 3 installed on the frame to form a weighing platform. In order to realize the weighing synchronous tare method of the belt scale, the frame 10 is fixedly installed with the base plate 5-1 of the tare load cell 5 at the predetermined distance from the load cell of the positive process segment in the return section of the conveyor belt. The upper bears the scale frame 5-2 whose two ends extend downwards from the support plate, and the two support plates support th...

Abstract

The invention relates to a belt weigher weighing synchronous skinning method and a belt weigher which realizes the method, belonging to the weighing measurement technical field. In the method, as a tare weight sensing device is arranged at the position of the prearranged distance from the delivery belt returning section of a belt weigher frame to a positive advancing section belt weighing sensor, after the weighing of the belt weigher runs, the gross weight data that the bearing delivery belt passes through the positive advancing section weighing sensor and the tare data that the empty-loaded delivery belt passes through the returning section tare weight sensing device are recorded; the lagged time of the delivery belt running from the weighing sensor to the tare weight sensing device is worked out according to the running speed of the delivery belt and the prearranged running distance; finally, the skinned net weight data is obtained by taking away the tare weight data recorded in the lagged time from the real-time recorded gross weight data. As the method of the invention realizes deducting the synchronous tare weight during the skinning, whether the delivery belt is abraded or bonded to material, the net weight data with enough precision can be obtained; compared with the prior art, the method of the invention has outstanding practical characteristics and obvious progress.

Description

technical field [0001] The invention relates to a tare method for weighing with a belt scale, in particular to a synchronous tare method for weighing with a belt scale, and also relates to a belt scale for realizing the method, belonging to the technical field of weighing and measurement. Background technique [0002] The belt scale is the most efficient and widely used among all kinds of bulk material automatic accumulative weighing instruments at present. Its typical structure and principle are: the weighing mechanism of the belt scale is installed on the frame of the belt conveyor, and placed on the conveyor The belt is below the belt, and the material is conveyed above the conveyor belt. When the conveyor belt carries the material through the weighing platform of the belt scale, the load sensor is affected by the gravity of the material, the self-weight of the mechanical components of the force measuring device and the weight of the conveyor belt on the weighing platform...
