The first driving mechanism 24 is a screw rod, and the spacing is changed by driving the first driving mechanism 24. One is to adapt to rubber waterstops of different thicknesses, and the other is to apply a certain pre-pressure to the upper rubber waterstop. The pre-pressure can make the winding tighter. In addition, by applying the pre-pressure, it can be transported backward under the drive of the motor 26.

[0022] Specifically, the second movable roller 33 is slidably connected to the top of the second fixed roller 32 through a sliding column 35. The second driving mechanism 34 is a cylinder. The second driving mechanism 34 drives the change of the spacing. First, it can adapt to rubber waterstops of different thicknesses. Second, it can apply a certain pre-pressure to the lower rubber waterstop. The pre-pressure can make the winding tighter.
