Description

Technical Field

[0001] The utility model mainly relates to the field of dynamic scales, and in particular to a rejecting device used in conjunction with dynamic scales. Background Art

[0002] The dynamic detection scale uses a microcomputer super chip from the American AD company, featuring 24-bit output without missing codes and AD conversion 2000 times / second, ensuring dynamic weighing. It also has built-in FIVDSP™ anti-vibration technology to ensure accurate weighing even under vibration conditions. It has a built-in power supply filter and the circuit adopts multi-stage digital filtering and other anti-interference designs. The large-capacity ferroelectric memory has sufficient capacity to record detection data and permanently store the data. The speed regulation module adopts a closed-loop constant speed control method, with button setting and digital display of speed. Once the conveyor belt speed is set, it can ensure that each belt section runs at a constant speed and the speed of each conveyor belt section is consistent. The use of a detachable conveyor belt facilitates maintenance. Strict high and low temperature tests and anti-interference tests ensure that the instrument can adapt to various complex on-site environments.

[0003] When dynamic weighing is used to weigh objects, a rejection device is required to transport unqualified objects to avoid mixing qualified and unqualified objects.

[0004] During the operation of the specific embodiment, the inventors found the following defects:

[0005] When the rejection device rejects the object, it directly pushes the object to slide on the top of the dynamic scale. The bottom of the object and the contact surface of the dynamic scale are rubbed, which can easily cause damage to the bottom of the object. The push will affect the weighing balance of the dynamic scale, resulting in inaccurate weighing of the dynamic scale in the later stage.
