Weighing body for double row hopper

Abstract

The invention discloses a weighing device which is used in a double-row hopper and which comprises a driving system and a weighing system. The driving system consists of an upper hopper driving mechanism, a lower hopper driving mechanism, an upper hopper driving cam and a lower hopper driving cam; the upper hopper driving cam and the lower hopper driving cam are arranged on a same shaft; the upper hopper driving cam and the lower hopper driving cam, which are driven by a same motor, are respectively used for driving the upper hopper driving mechanism and the lower hopper driving mechanism. The weighing system comprises a weighing sensor; one end of the sensor is fixed on the base of the weighing device through the mounting base of the sensor, and the other end is connected with a load-bearing component. The weighing device integrates the driving system with the weighing system and overcomes the difficulty of complex structural and driving control in the weighing device which is respectively driven by two hoppers. The combination of the driving system and the weighing system of the weighing hopper overcomes the defects of time consumption and poor accuracy when the weighing system is stabilized, and achieves the technical effects of simplifying the structure, reducing the space for installation, simplifying the control, decreasing the tare, and improving the weighing accuracy.

Description

technical field [0001] The invention relates to a weighing device, in particular to a weighing body for a double-row hopper. Background technique [0002] Combination scales have been widely used in automatic packaging systems. The commonly used double-row bucket combination scale, the two rows of buckets are installed according to the upper and lower positions, the upper row of buckets is the collecting bucket, and the lower row of buckets is the weighing bucket. The material is put in the weighing hopper through the collecting hopper, and its weight is weighed by the weighing system, and then it is packaged and other operations. The opening and closing of the collecting hopper and the weighing bucket door are controlled and completed by the driving mechanism. [0003] In the weighing system, the weighing sensor mainly adopts the resistance strain type load cell. When installing, one end of the sensor is fixed, the other end is movable, and the movable end is installed wi...
