Description
Technical Field
[0001] The utility model relates to the technical field of rubber roller production, in particular to a film wrapping device for a rubber roller. Background Art
[0002] The rubber roller is a cylindrical object made of rubber material, with a diameter usually between tens of millimeters and one meter and a length between tens of centimeters and several meters. According to different uses and materials, rubber rollers can be subdivided into many types, such as electrical insulation rubber rollers, rubber rollers for plastic processing, rubber rollers for rubber processing, rubber rollers for printing, etc., as well as special rubber rollers used in various industries such as steel, mining, chemicals, textiles, papermaking, and medicine. After the rubber roller is manufactured, it is usually necessary to use a film wrapping device to wrap a protective film on the outer cylindrical surface of the rubber roller. The protective film can protect the outer cylindrical surface of the rubber roller; the existing film wrapping equipment includes a lathe and a round rod inserted in the inner hole of the protective film roll. The film wrapping step is to install the rubber roller on the lathe, and the round rod is inserted in the inner hole of the protective film roll. The worker holds the round rod and moves it. As the lathe works, the rubber roller is driven to rotate, and the protective film is spirally wrapped on the outer cylindrical surface of the rubber roller.
[0003] With respect to the above-mentioned related technologies, the inventors found that when workers hold the round rod and move it, the speed of the protective film roll is easily uneven, which in turn makes the thickness of the protective film wrapped on the outer cylindrical surface of the rubber roller different, reducing the wrapping effect. In addition, the workers need to drive the protective film roll to move back and forth for a long time, which increases the labor intensity of the workers. After the wrapping work of the rubber roller is completed, the workers usually tear off the protective film by hand, making the broken part of the protective film uneven, reducing the use effect.

The protective film is wrapped around the outer cylindrical surface of the rubber roller in a state, which enhances the uniformity of the protective film wrapped around the outer cylindrical surface of the rubber roller and the wrapping effect. After the wrapping work of the rubber roller is completed, the protective film is held and moved toward the cutting component and pushed hard. The cutting component can cut the protective film without the need for workers to tear the protective film by hand. The broken part of the protective film is relatively flush, which improves the use effect. The clamping component is used to fix one broken part of the protective film to prevent the end of the protective film from floating at will, which is convenient for workers to disassemble and assemble the rubber roller. The workers completely wrap the other broken part of the protective film on the rubber roller and fix the broken part of the protective film to achieve the purpose of wrapping the rubber roller with the protective film.
