[0002] Lenses are transparent materials with one or more curved surfaces made of optical materials such as glass or polyurethane. They are often used in the fields of optics, photography, or lasers. Currently, the molds for making polyurethane lenses usually use two molds (one mold A and one mold B). After wrapping with tape, polyurethane is poured into the cavity formed by the two molds and the tape to make polyurethane lenses. The tape is used to seal the edges of the poured polyurethane mold.

[0003] During the production process of the tape, it is processed by multiple equipments, among which unwinding is one of the processes. When unwinding the tape, a special unwinding mechanism is usually used, and the unwinding operation is realized by driving the unwinding roller to rotate. The unwinding roller includes a tube core 7 and a film 8 wound on the tube core 7.

However, this method is inconvenient to operate and reduces the efficiency of disassembly and assembly of the unwinding roller. Utility Model Content

The support tube 10 is used to guide the sliding block 16, the sliding block 16 is fixedly connected to the moving block 18, and the electric telescopic rod 19 is used to drive the moving block 18 to move back and forth. When the unwinding roller is in a fixed state, the gravity exerted on the unwinding roller acts on the support tube 10, providing support for the unwinding roller, reducing the vertical pressure exerted on the electric telescopic rod 19, and extending the service life of the electric telescopic rod 19.

[0022] The electric telescopic rod 19 can drive the moving block 18 to move, and synchronously drive multiple sliding blocks 16 to reciprocate along the length direction of the support tube 10.
