Technical Field

The invention relates to the field of detection equipment, in particular to a weight sensor constructed on a linear transmission mechanism.

Background

The weight sensor is one of important members in a sensor family and is widely applied to various fields. Which is more indispensable as an integral part of the screening line. For example, a poultry slaughtering production line usually adopts a chain conveying mode, a large chain conveying loop is constructed in a working area, workers are configured at each working procedure stage of the loop to cut a working object, and then the working object is screened for subsequent operation.

In the existing chain type conveying mechanism, most of the screening means need to take the articles on the conveying chain off and then place the articles on the weighing mechanism for weighing and screening. This form is mainly limited by the fact that the existing weight sensors are basically built on the pressure sensing principle, and the weight of the article is determined by the pressure in the vertical direction. This also results in the need to weigh and sort the items on the chain, which requires removal of the chain, such as duck necks, and the need to remove each duck neck from the chain to weigh separately when weighing is required. For the traditional weighing application of the pressure sensor, if the traditional weighing application of the pressure sensor is directly combined with a chain conveying mode, the pressure sensor needs to be arranged at each article bearing position of a chain, the equipment cost is increased undoubtedly, and the maintenance is inconvenient, so that the scheme provides the sensor which can be suitable for feeding back the weight of the articles in the chain conveying process.
