Example 2

[0024] Figure 1-4The present invention shows a concrete anti-cracking fiber positioning and cutting device according to an embodiment of the present invention, which includes: a support platform 1: the surface of the support platform 1 is fixedly connected to the support frame 2 by bolts, the top of the support frame 2 is fixedly connected to the motor 3 by bolts, the left and right sides of the support platform 1 are fixedly connected to the support vertical plates 4 by bolts, the opposite sides of the two support vertical plates 4 are fixedly connected to the guide grooves 5 by bolts, the surfaces of the two guide grooves 5 are slidably connected to the guide heads 6, a support horizontal plate 7 is fixedly connected between the two guide heads 6, the top of the support horizontal plate 7 is rotatably connected to the connecting rod 8, the output shaft of the motor 3 is fixedly connected to the cam 9 by a flange, the top of the connecting rod 8 is connected to the surface of the cam 9 The bottom of the supporting cross plate 7 is fixedly connected to the cross bar 10 by bolts, and a pressure structure 11 is provided on the front and rear sides of the cross bar 10.
