As can be seen, the top surface of each vertical plate 32 in this embodiment constitutes the support portion.
The horizontal plate 31 may be a plastic plate, and the vertical plate 32 may be an aluminum alloy plate or a nylon plate.
As shown in fig. 1, a base 4 is arranged below the roller conveying section, and the weighing frame is fixedly arranged on the base 4 through a connecting piece. The pressure sensor is specifically arranged between the connecting piece and the weighing frame.
Referring to fig. 3, the structure of the driving mechanism includes a cylinder 5, a cylinder body of the cylinder 5 is fixedly arranged on a frame 8, and a piston rod of the cylinder 5 is fixedly connected with the supporting side plate 2 through a connecting piece.

under normal operating condition, the roller transmission section is located and stops the position, and product (parcel or receiver etc.) is carried to being in from the upper reaches on the roller transmission section of stopping the position, the roller transmission section is driven down to stopping the position down at the cylinder, because the supporting part stretches out in the clearance between the adjacent cylinder, can make the product fall on the supporting part and be weighed by pressure sensor. After weighing, the roller transmission section is driven by the air cylinder to rise to an upper stop position, and the product is supported by the roller again and is conveyed to the downstream direction because the top end of the roller is higher than the supporting part.
Unlike conventional dynamic weighing using a belt scale, the lifting type dynamic scale of the embodiment actually performs static weighing in the dynamic conveying process, even if a product is separated from a conveying transmission roller and is in a temporary static state when being weighed, thereby avoiding weighing errors caused by movement acceleration and greatly improving the accuracy of a weighing result.
