Abstract

The invention relates to an on-line steel billet weighting device which has the technical scheme that a weighting rack (7) is provided with 3-6 conveying rollers (3) and a driving motor (5); a motor control relay (25) and a brake control relay (26) which are respectively corresponding to the driving motor (5) and a brake (10) are respectively connected with a digital output channel DO of a PLC (24); 2-5 electromagnetic directional valves (20) are connected with a locating piston rod type hydraulic cylinder (9) by pipelines which are provided with pressure sensors (22), and each electromagnetic directional valve (20) and each pressure sensor (22) are respectively connected with the digital output channel DO and an analogue input channel AI of the PLC (24); four weighing sensors (15) and infrared receivers (2) the analogue input channel AI and a digital input channel DI of the PLC (24); control software is written into an internal memorizer of the PLC (24), and configuration software is written into an internal memorizer of a touch screen (23). The line steel billet weighting device has the characteristics of rapid on-line weighting, accuracy, small impact and low cost.

Description

technical field [0001] The invention belongs to the technical field of weighing devices. In particular, the utility model relates to an online billet weighing device for a plate or wire production line in the iron and steel industry. Background technique [0002] As an important means of measurement in the modern iron and steel industry, billet weighing is the basis for evaluating production indicators. The continuous production of modern iron and steel industry is strong, and there is an urgent need for an online weighing device, which can quickly and accurately weigh the weight of each billet directly on the production line, and upload the data at the same time. [0003] The online billet weighing device is mainly used for billet weight measurement on the production line, and the existing billet weighing device is separated from the conveying device, which will cause the following problems: ①Weighing takes a long time and affects the production rhythm; ②For The conveying...
