Description

Technical Field

[0001] The utility model relates to a multi-scale online weighing scale protection device. Background Art

[0002] The existing online weighing scale protection method is that the scale head is fixed and there is a protection platform above the scale head. Each time weighing, the protection platform needs to be lowered, and then the weighing scale head protrudes for online weighing. However, this method can only protect a single scale separately and cannot protect multiple scales at the same time. There is also a problem that when the object I weigh is overloaded, the downward pressure is too large and there is no overload protection, which makes the scale easily damaged. In addition, when the object is transmitted during online weighing, it is in a moving state. There is a possibility that the object may tilt and collide with the scale laterally, causing the scale to be subjected to lateral force, thereby causing the scale to be damaged. Therefore, a multi-scale online weighing scale protection device is proposed to address the above problems. Utility Model Content
