Description

Technical Field

[0001] This utility model relates to the field of metering device technology, and in particular to an online metering device for weighing systems. Background Technology

[0002] Weights are an indispensable component of weighing systems. As a standard measuring instrument for transferring mass values, they play a crucial role in determining the mass of an unknown object. Weights are typically metal blocks or sheets with a known and calibrated mass. By comparing them with the object being measured on a balance or scale, the mass of the object is determined. The accuracy of the weights directly affects the measurement results of the weighing equipment and is fundamental to ensuring the precision of the weighing system. In industrial production, scientific research, and commercial trade, weights are not only used for routine mass measurement but also for calibrating other measuring instruments and equipment, such as balances and load cells, ensuring that these instruments and equipment achieve the required measurement accuracy.

[0003] As a standard measuring instrument for transmitting mass values, the accuracy of weights directly affects the measurement results of weighing equipment. Therefore, they need to be calibrated. During long-term use, the mass value of weights may change due to factors such as wear and corrosion. Therefore, they must be calibrated and verified regularly to ensure the accuracy and consistency of mass value transmission, as well as to ensure product quality and compliance. Existing technologies lack fast, effective, and accurate measuring devices. Therefore, this utility model proposes an online measuring device for weighing systems to solve the problems existing in the prior art. Utility Model Content

This device uses a support to hold weights, rollers to guide a steel wire rope, and a sliding block connected to one end of the rope. A cylinder applies force to rotate a connecting rod, which in turn rotates a connecting rod, which in turn moves the sliding block, pulling the steel wire rope and thus the weights at the other end. The reaction force data generated by the cylinder's applied force is used to measure the weights, enabling calibration—a fast, effective, and accurate process.

[0005] To achieve the purpose of this utility model, the utility model is implemented through the following technical solution: an online measuring device for a weighing system, including a first profile and a second profile, the second profile being disposed on one side below the first profile, rollers being provided on both sides of the first profile, and steel wire ropes being wound on the rollers, one end of the steel wire ropes being connected to a support member, and the support member being used to place weights.

[0010] A further improvement is that a cylinder seat is provided on the upper side of one side of the second profile, and a hinge joint is provided on one side of the cylinder seat, and the cylinder is hinged to the hinge joint.

[0011] A further improvement is that a support is provided on the lower side of one side of the second profile, and one end of the connecting rod is hinged to the support.

[0012] A further improvement is that a linear slide rail is provided at the bottom of one side of the second profile, and the sliding block is slidably installed with the linear slide rail.
