A full-degree-of-freedom hanging electronic quantitative packaging scale weighing device

Abstract

The invention discloses a weighing device of a suspension type electronic quantitative packing scale with all degrees of freedom. The weighing device comprises a weighing container; three fixed seats are respectively arranged at an opening of the weighing container along three directions; the distances among the fixed seats are equal to one another, and the fixed seats are arranged in an equilateral triangle; each fixed seat is provided with a sensor component; the sensor component comprises a sensor bracket; each sensor bracket is provided with a weighing sensor; the lower ends of the sensor brackets are respectively provided with an adjusting connecting rod; the bottom ends of the adjusting connecting rods are respectively provided with a cylindrical horseshoe hanging ring; the cylindrical horseshoe hanging rings are respectively connected and matched with cylindrical pin shafts respectively arranged at the outer ends of the fixed seats; the middle parts of the cylindrical pin shafts are respectively provided with a waist-shaped groove, and the waist-shaped grooves are respectively matched with the cylindrical horseshoe hanging rings; signal output lines of the three weighing sensors are arranged in parallel and then can transmit signals into a controller. According to the weighing device, the cylindrical horseshoe hanging rings are in point contact with the cylindrical pin shafts, so that the frictional force is minimum or can be neglected, the possibility that force is suppressed can not be caused, and the accuracy of weighing is indirectly guaranteed.

Description

technical field [0001] The invention relates to a weighing device of a full-degree-of-freedom hanging electronic quantitative packaging scale. Background technique [0002] The extensive application of electronic quantitative packaging scales in material packaging enterprises has prompted the continuous advancement and innovation of electronic quantitative packaging scales. [0003] With the development of the material packaging industry, the competition is becoming more and more fierce, and most enterprises are pursuing high production efficiency. The requirements for packaging speed and accuracy of electronic quantitative packaging weighing are getting higher and higher. However, the mature technology of electronic quantitative packaging scales has been used for a long time, and it is very difficult to increase the speed a little while ensuring the accuracy. [0004] There are two aspects that affect the weighing speed, one is the batching speed of the batcher (commonly ...

Problems solved by technology

For example: joint bearings (commonly known as fish-eye joints) are used to connect the adjustable sensor components and weighing containers. The adjustable range of joint bearings is limited, and the middle bearing hub and bearings are arc-fitted. There is a surface contact between the arc and the arc, and the friction is relatively large. The degree of flexibility between them directly limits the stable speed of the weighing container.
