我们对竹编工匠用的手摇劈篾机进行了两点改进,结果,一是劈平薄形竹篾时功效可提高一倍,二是可加工出用途广泛的方形竹篾。 1.增加一对变速齿轮,出篾速度提高一倍改前如图1,手摇手轮转动一圈,上下滚筒各转动一圈,出篾长度为πD(圆周率乘以滚筒直径)。改后 We made two improvements to the hand-cleavers used by bamboo weaving craftsmen. As a result, the effect of doubling and thinning the bamboo can be doubled, and the square can be processed to a wide range of uses. 1. Add a pair of speed change gears, double the speed of change. As shown in Figure 1, the handwheel rotates one turn, and the upper and lower rollers rotate one turn each. The length of the output is πD (pi multiplied by the diameter of the roller). After the change
