Aiming at the problem of low efficiency of manual binding of anchor nets in coal mine tunneling faces, a mine anchor net binding device is proposed. The handheld actuator is the terminal actuator of the mine anchor net binding device. In order to deeply understand its working mechanism and verify the design reliability, the wire feeding, wire cutting and wire twisting processes of the binding mechanism were simulated and analyzed by using SolidWorks software and ANSYS software, respectively. It was concluded that the peak torque of the wire feeding gear during operation was 0.19 N·m, the peak torque of the slicing sheet was 0.54 N·m, and the peak torque of the wire twisting shaft was 0.40 N·m. The multi-body dynamics simulation for the transmission system of the binding mechanism was carried out by using ADAMS software, and the speed characteristic curve of the transmission components during operation and the load characteristic curve of gear meshing transmission were obtained. Based on the ANSYS software, the finite element simulation analysis for the gear meshing motion of the binding mechanism was carried out, and the stress distribution cloud maps of the gear mating surface during the meshing process were obtained. The contact fatigue strength and bending fatigue strength of the gears were checked and verified according to the calculated allowable stress. Finally, an anchor net binding device prototype and a handheld actuator input test platform were built, and the binding performance verification experiments were carried out. The experimental results showed that the performance of the handheld actuator was basically consistent with the simulation analysis results. The binding action was continuous and efficient, and the time for a single binding operation cycle was 1.8 s. The binding effect met the design requirements and actual application needs. The research results provide a theoretical basis for the optimal design and engineering application of the mine anchor net binding device.
