Abstract

The patent provides a hub wheel and filter rod composite forming machine with filter rod detection function, comprising a hub wheel main body, a filter rod anti-blocking induction assembly, a filter rod missing induction assembly and a filter rod length induction assembly. The three filter rod induction assemblies monitor different transport parts of the hub wheel main body, and the three filter rod induction assemblies work independently in parallel, so that any abnormal signal can independently trigger the control mechanism to stop or alarm, realizing rapid response of multiple fault modes. The patent is different from the anti-blocking design of the traditional mechanical fork structure. Through the synergistic effect of the anti-missing inlet and the anti-blocking outlet, the stable conveying of the filter rod in high-speed circular motion is ensured, and the filter rod sticking rate is greatly reduced. At the same time, a straight pipe joint capable of automatically cleaning the sensor is arranged on the three filter rod induction assemblies, which avoids dust interference with detection accuracy, further prevents blockage and ensures long-term operation reliability.
