Dynamic load weighing module

Abstract

The invention discloses a dynamic load weighing module, which comprises an upper top plate, an upper ball socket, a lower ball socket bearing rod, a lower ball socket cover, a weighing sensor and a lower bottom plate, the upper ball socket is fixedly connected to the bottom of the upper top plate, a cavity is formed in the upper ball socket, the bottom of the upper ball socket is open, the top of the lower ball socket force bearing rod is located in the cavity of the upper ball socket, semicircular concave ball sockets are arranged on the top of the lower ball socket force bearing rod and the top of the cavity of the upper ball socket, and a steel ball is arranged between the two concave ball sockets. A bottom opening of the upper ball socket is connected with a lower ball socket cover, and the bottom of a lower ball socket force bearing rod is connected with a load bearing end of a weighing sensor; the diameter of the top of the lower ball socket force-bearing rod is larger than that of other parts, a downward step surface is formed between the top of the lower ball socket force-bearing rod and the other parts, and when the top of the lower ball socket force-bearing rod and the inner concave ball sockets at the top of the upper ball socket cavity are both attached to the steel ball, the step surface of the lower ball socket force-bearing rod and the top of the lower ball socket cover are arranged in a clearance mode; the fixed end of the weighing sensor is fixedly connected with the lower bottom plate, and the weighing sensor and the lower bottom plate are arranged in a spaced mode.

Description

technical field [0001] The invention belongs to the field of weighing sensors and relates to a dynamic load weighing module. Background technique [0002] In chemical industry, petroleum, metallurgy, paint and other industries, there are a large number of liquid raw materials. During the production process of these industries, the raw materials need to be weighed, measured and mixed to ensure that the finished product is qualified. These reaction kettles and mixing tanks generally have a stirring function, which will inevitably generate internal stirring force, and the use of the motor will also cause vibration. If the material tank exists in an outdoor environment, it may also be affected by uncontrollable external forces such as wind load and air flow. These factors will affect to the accuracy of weighing. [0003] The existing traditional weighing module includes upper plate, sensor, lower base plate, load-bearing bolts, etc. This structural product is weighed through ri...

These reaction kettles and mixing tanks generally have a stirring function, which will inevitably generate internal stirring force, and the use of the motor will also cause vibration. If the material tank exists in an outdoor environment, it may also be affected by uncontrollable external forces such as wind load and air flow. These factors will affect to the accuracy of weighing

[0003] The existing traditional weighing module includes upper plate, sensor, lower base plate, load-bearing bolts, etc. This structural product is weighed through rigid force-transmitting parts, and its advantage is that it can adapt to the on-site material tank by adjusting the height of the bolts. Supporting legs, but the disadvantages are also more obvious: the weighing accuracy can be guaranteed only when it is subjected to vertical force, but when it is subjected to horizontal force and lateral force, the weighing accuracy cannot be guaranteed

When the lateral force is too large, it may also cause damage to the sensor
