Weighing body for double opening door hopper

Abstract

The invention discloses a weighing device which is used in a double-door hopper and which comprises a driving system and a weighing system. The driving system comprises a left driving cam and a right driving cam which are arranged on two sides of a motor. Respectively through the linkage mechanism consisting of a left pull rod, a right pull rod, a left connecting rod, a right connecting rod, a left swing link, a right swing link, a left deflector rod and a right deflector rod, the left driving cam and the right driving cam drive the left deflector rod and the right deflector rod to swing and drive the hopper to open or close.. The weighing system comprises a weighing sensor; one end of the sensor is fixed on a machine foundation, and the active end is connected with a connecting frame so that the driving system can be arranged on the connecting frame. The driving system is integrated with the weighing system to form one body. In the proposal which integrates the driving system with the weighing system, the spring on the weighing hopper is built in the driving system. 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-door hopper. Background technique [0002] Combination scales have been widely used in automatic packaging systems, and three-row bucket combination scales have been widely used due to their advantages. In the three-row hopper combination scale, there is a weighing hopper in the middle, a collecting hopper on the top, and a memory hopper on the bottom. The materials are distributed through the collecting hopper and weighed in the weighing hopper. The materials in the weighing hopper can be directly discharged and packaged. operation, it can also be discharged into the memory bucket to participate in the next combined discharge. In the three-row bucket combination scale system, the weighing bucket uses a double-door hopper. The so-called double-door bucket mainly refers to a storage container with two doors at the bottom, and any one of the doors can be independen...
