The invention relates to a tension control device for winding of a glass fiber reinforced plastic anchor rod. The tension control device comprises a winding motor, a left paying-off motor and a right paying-off motor, which are all arranged on a rack, a main driving axle system arranged on the rack, a left paying-off axle, a right paying-off axle, a winding motor, a left paying-off axle sprocket wheel and a right paying-off axle sprocket wheel, wherein a turntable is fixed at the right end of the main driving axle system, the left paying-off axle and the right paying-off axle are symmetrically arranged on the turntable, a winding output sprocket wheel, a left paying-off output sprocket wheel and a right paying-off output sprocket wheel are arranged on the output shafts of the left paying-off motor and the right paying-off motor respectively, the left paying-off axle sprocket wheel and the right paying-off axle sprocket wheel are arranged on the left paying-off axle and the right paying-off axle respectively, and the sprocket wheels are connected with a sprocket wheel group on the main driving axle system. In a preformed glass fiber reinforced plastic anchor rod transferring process, a forming filament is symmetrically and helically wound on the preformed glass fiber reinforced plastic anchor rod and the forming filament winding operation can be directly finished.
Description
technical field [0001] The invention relates to a tension control device, in particular to a tension control device for winding and forming in the production of glass fiber reinforced plastic anchor rods. Background technique [0002] Bolt support is a safe and economical support method. It binds the surrounding rock of the roadway together, so that the surrounding rock can support itself. It is the most basic component of the roadway support in contemporary coal mines. At present, bolts are not only used in mines, but also in engineering technology to actively reinforce slopes, tunnels, and dams. There are different types of anchor rods, and the commonly used fiberglass anchor rods are all provided with threads. [0003] The forming process of the FRP anchor rod is to wind the preformed FRP anchor rod with a constant tension forming wire to outline the thread. The turntable carries the molding wire and revolves around the mandrel, and at the same time the molding wire rot...
