AI Technical Summary
When the existing unwinding device is retracted, the waterproof coil is prone to wrinkles and unstable, resulting in lower roll quality.
An unwinding device including a base, a fixing plate, a drive motor, a rotating shaft, a rolling roller, a chain, a slider, a slider, a support rod and a rotating roller are designed. By driving the motor to rotate the chain and the shaft, the unwinding roller winds the waterproof coil. As the roll becomes larger and larger, the roll roll presses the rotating roller downward, and the rotating roller drives the slider and limit block to slide through the side plate, support rod and slide block to achieve stable extrusion of the roll.
It effectively prevents wrinkles from occurring during rolling of waterproof rolls, and improves the rolling quality of rolls through extrusion mechanism.

[0002] Waterproof membrane refers to a waterproof material product made by impregnating asphalt or polymer waterproof materials on a carcass. It is provided in the form of a roll and is called waterproof membrane. Waterproof membrane is mainly used for building walls, roofs, tunnels, roads, landfills, etc. It is a kind of flexible building material product that can be rolled into a roll to resist the seepage of external rainwater and groundwater. As a leak-free connection between the project foundation and the building, it is the first barrier to waterproofing the entire project and plays a vital role in the entire project. The products mainly include asphalt waterproof membrane and polymer waterproof membrane.
[0003] However, when the unwinding device currently on the market is working, the waterproof membrane is generally directly wound on the winding roller. The waterproof membrane will be wrinkled when winding, and since there is no squeezing device, the waterproof membrane will be unstable when winding, resulting in low quality of the waterproof membrane roll. For this reason, we propose an unwinding device for waterproof membrane production. Utility Model Content
