Embodiment
[0021] Such as figure 1 with figure 2 The shown is a polymer non-asphalt-based coiled material sand setting equipment, including a feeding system that drives the coiled material to run, and a sand leakage mechanism is provided above the coiled material. When it is necessary to place a layer of patterned sand on the coiled material The sand is placed while the coil is running. The sand leakage mechanism includes an outer cylinder 1, an inner cylinder 2 and a rotating shaft 3. The inner cylinder 2 has a space for containing sand, and the inner cylinder 2 is placed in the outer cylinder 1. The inner cylinder 2 can be Relative to the rotation of the outer cylinder 1, the inner cylinder 2 and the rotating shaft 3 are driven and coordinated, and the rotating shaft 3 is driven by the driving mechanism to drive the rotating shaft 3 to rotate through the driving mechanism. There are sand leakage points 4 on the inner cylinder 2, wherein the sand leakage points 4 on the inner cylinder...
