Problems solved by technology

The frame-type weighing platform is heavy and requires a large number of sensors, which is uneconomical. In order to improve stability and accuracy, the traditional roller-type weighing platform uses at least two sets of weighing units, and the number of sensors required for weighing will not be less than four. According to the belt scale error theory E=±2KdFp / nqa 2 , if more rollers n are used to reduce the error, more weighing units and sensors are required, the structure is complex and uneconomical, and it cannot meet the requirements of some old-fashioned roller scales transform

Abstract

The self-linking double roller weighing device is characterized in that it includes a rectangular frame composed of two parallel rollers (7) and two parallel connecting plates (1), which are respectively installed in the middle of the two connecting plates The two small shafts (9), the two small shaft fixing seats (3) respectively arranged on the outside of the connecting plate, and the two small shaft fixing seats are respectively connected with the load cell (2). The invention can make the weighing device simple in structure, light in weight, compact in structure and high in weighing accuracy under the condition that the installation size of the original single roller weighing unit remains unchanged and the number of sensors remains unchanged.

Description

technical field [0001] The invention relates to the technical field of electronic belt scales. Background technique [0002] At present, the weighing devices of electronic belt scales widely used in the tobacco industry basically have the following types: single-sensor lever scale, double-sensor lever scale, double-sensor single-roller direct pressure scale, four-sensor double-roller straight Weighing platform and so on. Due to too many intermediate link factors, the leverage weighing platform has gradually been eliminated; the direct pressure weighing platform, if a frame weighing platform is used, more than three sensors must be used to support a weighing platform, and the existing general The minimum weighing unit of the idler type is a single idler, and one or two (must be two when the bandwidth is wide) sensors must be used to support a weighing roller. Two or more weighing units must be used. Use more sensors to support it. The frame-type weighing platform is heavy ...
