Description

Technical Field

[0001] This utility model relates to the field of unwinding equipment technology, specifically to a dust-free paper unwinding device. Background Technology

[0002] Cleanroom wipes are widely used in hygiene products, specialty medical supplies, and industrial wiping products. Unwinding is a crucial step in the production of cleanroom wipes.

[0003] During the unwinding process, as the diameter of the paper roll gradually decreases, it becomes difficult to ensure the stability of the unwinding, which can easily cause slippage. Traditional unwinding equipment does not have an anti-slip structure, which affects the unwinding efficiency. Furthermore, if the unwinding speed is too fast, the clean paper may not be fully unrolled, resulting in wrinkles. Existing equipment does not have a wrinkle removal structure. Utility Model Content

[0004] The main objective of this invention is to provide a dust-free paper unwinding device to solve the aforementioned technical problems.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a dust-free paper unwinding device, comprising a base, on which a first frame and a second frame are provided, and on the first frame and the second frame respectively, an unwinding roller and a take-up roller are provided, and on one side of both the first frame and the second frame, a first motor is provided; a limiting mechanism is provided on the first frame; and a wrinkle removal mechanism is provided between the first frame and the second frame.

[0006] Based on the above scheme and as a preferred embodiment of the above scheme: the limiting mechanism includes a cylinder hinged to the first frame, the output end of the cylinder is hinged to a limiting rod, one end of the limiting rod is hinged to the first frame, and the other end of the limiting rod is movably provided with a limiting wheel.

[0007] Based on the above scheme and as a preferred embodiment of the above scheme: the number of the limiting mechanism is 4 sets, and the limiting wheel can contact the upper and lower positions of both sides of the dust-free paper roll.

[0008] Based on the above scheme and as a preferred embodiment of the above scheme: the wrinkle removal mechanism includes two sets of mounting plates symmetrically arranged on the base. Each mounting plate is fixed with two sets of second motors. The output end of the second motor is provided with inclined wrinkle removal rollers, one of which is located above the dust-free paper and the other is located below the dust-free paper.

[0009] Based on the above scheme and as a preferred embodiment of the above scheme: the angle between the inclined depletion roller and the axis of the dust-free paper along its length is 45°.

[0010] The beneficial effects of this utility model are as follows: The limiting mechanism in this equipment consists of a cylinder, a limiting rod, and a limiting wheel 80, and the number of these components is set. It can contact the upper and lower positions of both sides of the dust-free paper roll, and can stably constrain the dust-free paper roll from multiple directions, effectively preventing the paper roll from shifting or shaking due to uneven force or external interference during the unwinding process. The slanted roller pressing action of the wrinkle removal mechanism can effectively stretch the paper and eliminate wrinkles caused by curling stress and conveying friction during the unwinding process, ensuring that the dust-free paper remains flat and smooth after processing.

[0013] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. However, the specific implementation methods and embodiments described below are for illustrative purposes only and are not intended to limit the present invention.

[0014] See attached diagram. Figures 1 to 2 The dust-free paper unwinding device in this embodiment includes a base 1, a first frame 2 and a second frame 3 on the base 1, an unwinding roller 20 and a take-up roller 30 respectively on the first frame 2 and the second frame 3, a first motor 4 on one side of the first frame 2 and the second frame 3, a limiting mechanism on the first frame 2, and a wrinkle removal mechanism between the first frame 2 and the second frame 3.

[0015] Furthermore, the limiting mechanism includes a cylinder 7 hinged to the first frame 2, a limiting rod 8 hinged to the output end of the cylinder 7, one end of the limiting rod 8 hinged to the first frame 2, and a limiting wheel 80 movably provided at the other end of the limiting rod 8.

[0016] Furthermore, there are 4 sets of limiting mechanisms, and the limiting wheels 80 can contact the upper and lower positions of both sides of the dust-free paper roll.

[0017] Furthermore, the wrinkle removal mechanism includes two sets of mounting plates 5 symmetrically arranged on the base 1. Each mounting plate 5 is fixed with two sets of second motors 50. The output end of the second motor 50 is provided with inclined wrinkle removal rollers 6, one of which is located above the dust-free paper and the other is located below the dust-free paper.

[0018] Furthermore, the angle between the inclined de-folding roller 6 and the axis along the length of the dust-free paper is 45°.

[0019] The limiting mechanism in this equipment consists of a cylinder 7, a limiting rod 8, and a limiting wheel 80, and there are 4 sets of them. They can contact the upper and lower positions of both sides of the clean paper roll, and can stably constrain the clean paper roll from multiple directions, effectively preventing the paper roll from shifting or shaking due to uneven force or external interference during the unwinding process.

[0020] The wrinkle removal mechanism uses two sets of symmetrically arranged mounting plates 5. Each set of mounting plates 5 is equipped with two sets of inclined wrinkle removal rollers 6 driven by a second motor 50. The inclined wrinkle removal rollers 6 form a 45° angle with the axis of the cleanroom paper along its length. One set is located above the cleanroom paper, and the other set is located below it. This symmetrical and inclined arrangement can apply uniform tension to the cleanroom paper. The inclined roller action effectively stretches the paper and eliminates wrinkles caused by curling stress and conveying friction during unwinding, ensuring that the cleanroom paper remains flat and smooth after processing.

[0021] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
