In the production process of the rod and wire, a diameter measuring instrument is generally used for carrying out on-line detection on products, the diameter measuring instrument is mainly used for detecting and screening abnormal products in the rolling process in the prior art, timely and effective data can not be provided for automatic control, and the measuring accuracy of the diameter measuring instrument is easy to be influenced by the environment to generate fluctuation. The high temperature of the rod and wire during rolling produces a hot gas flow and vibration while running at high speed. The higher the running speed, the faster the vibration frequency, and the harder the measurement accuracy is ensured. Traditional deformed steel bar is complicated in appearance, and the diameter measuring instrument cannot detect the deformed steel bar in a high-speed movement state. The screw-thread steel is generally inspected by sampling, i.e. the finished product is taken off the production line and measured by a special external diameter measuring tool. If manual monitoring is not timely carried out, defective waste products with defects in appearance quality are caused.
For this purpose, systems have been developed which use visual recognition techniques to identify the sheared material produced during the rolling of the rod and wire. Firstly, the sheared materials are collected and conveyed to a specified detection platform through a sheared material collecting device arranged under a flying shear chute. After the shearing materials are visually identified on the detection platform, the length, the outer diameter, the cracks, the groove shape and the like of the shearing materials are included, the processed data information is finally transmitted to the control system, high-precision detection of the rod shearing materials is achieved, and finally the rod shearing materials are conveyed to the waste frame through the chute. However, in the process of falling the sheared materials, a gate capable of being opened and closed in a controlled manner is required to be designed for cooling and cleaning; in the process of multiple use, a general vertical lifting flashboard can be impacted by falling shearing materials, and the problems of flashboard deformation, driving connecting rod deformation, unsmooth lifting of the flashboard, incapability of opening or closing and the like can be caused along with the increase of the impact times.
