Description

Technical Field

[0001] The utility model belongs to the technical field of weighing machines, in particular to a fruit weighing device. Background Art

[0002] Weighing machines are tools that use Hooke's law or the principle of lever balance to measure the mass of objects. They are widely used in supermarkets, convenience stores, and all walks of life. Weighing machines are mainly composed of three parts: a load-bearing system (such as a tray, a scale body), a force conversion system (such as a lever force transmission system, a sensor), and a value display system (such as a dial, an electronic display instrument). When weighing fruits, existing weighing machines put the fruits directly on the tray for weighing. However, when weighing a large number of fruits, the fruits are easy to roll off the tray, causing inconvenience. Utility Model Content
