Embodiment Construction
[0037] In this example, first combine Figure 5 ~ Figure 7 Explain the working principle of the double guide wheel tensioner, for the convenience of explanation, Figure 5 ~ Figure 7 Four fixed wheels are adopted in the present embodiment, but in the actual embodiment, the fixed wheels on the outside of both sides are realized by crimping rods and guide wheels.
[0038] Such as Figure 5As shown, the rocker shaft is fixed at the center of the length direction of the rocker, and the rocker shaft is installed on the support. The drive energy is released and stored during the rotation of the direction. Rocker guide wheels are installed at both ends of the rocker.
[0039] Four fixed wheels are arranged in pairs, and among the two fixed wheels in each group of fixed wheels, one is positioned at the outside of the rocker guide wheel's circle of revolution, and one is positioned at the inside of the rocker guide wheel's circle of revolution.
[0040] Such as Figure 5 As shown,...
