Description

Technical Field

[0001] This utility model belongs to the field of unwinding technology, specifically relating to a fiber roll unwinding mechanism. Background Technology

[0002] Fibers are substances composed of continuous or discontinuous filaments. In plants and animals, fibers play a vital role in maintaining tissue structure. Fibers have a wide range of uses; they can be woven into fine threads, yarns, and ropes. In papermaking or felt weaving, they can also be woven into fiber layers. Fiber rolls are formed by winding a restraining layer, such as thermal insulation and flame-retardant fiber rolls, and polyester restraining thermal insulation and sound-absorbing rolls. Some fiber rolls are mounted outside a central support cylinder, while others are directly wound without a central support cylinder. Restraining rolls without a central support cylinder cannot use existing unwinding devices; therefore, it is crucial to develop a restraining roll unwinding mechanism that overcomes these shortcomings. Utility Model Content

[0003] To solve at least one of the above-mentioned technical problems, the present invention provides a fiber roll unwinding mechanism, including a placement platform, wherein an arc-shaped recess is provided on the placement platform for placing the fiber roll, and an outlet is formed on the first side of the arc-shaped recess. An unwinding assembly is installed on the placement platform on the side of the outlet. The unwinding assembly includes at least one rolling assembly and at least one driving assembly that cooperates with the rolling assembly. The rolling assembly includes a rolling bracket and a first roller rotatably connected to the outside of the rolling bracket.

[0004] The drive assembly includes an electric telescopic rod and a guide vertical rod parallel to the electric telescopic rod. A drive motor is fixed to the end of the electric telescopic rod. A rotating rod parallel to the first roller is fixed on the output shaft of the drive motor. A second roller is connected to the outside of the rotating rod. The fiber layer extending from the fiber roll is clamped between the first roller and the second roller.

[0005] A guide block is fitted onto the guide vertical rod, and a rotating groove is formed on the guide block. The end of the rotating rod is inserted into the rotating groove through a rotating bearing.

[0006] The guide block has a channel for the guide vertical rod to pass through, and a linear bearing that cooperates with the guide vertical rod is fixed on the inner wall of the channel.

[0007] The above technical solution reduces friction by using linear bearings.

[0008] An elastic connector is connected between the rotating rod and the second roller. The elastic connector includes an outer ring, an inner ring, and several connecting pieces connecting the inner ring and the outer ring. A first ring groove for installing the outer ring is formed on the inner wall of the second roller, and a second ring groove for installing the inner ring is formed on the outer wall of the rotating rod.

[0009] Through the above technical solution, the first and second annular grooves can achieve the installation stability of the elastic connector. The elastic connector is made of one-piece molded silicone or rubber material, which can realize the stable pressing of the fiber cloth by the two rollers and adapt to the thickness of various limiting parts.

[0010] Compared with the prior art, the advantages of this utility model are: the utility model has a simple structure and can be adapted to fiber rolls without a central support cylinder, and the fiber roll will always be in the arc-shaped depression due to gravity. Attached Figure Description
