Description

Technical Field

[0001] The utility model relates to the technical field of adhesive tape winding, in particular to an adjustable winding device. Background Art

[0002] Tape production winding refers to the process of transferring tape material from the mother roll to the sub-roll. This process is usually completed on the tape production line. The entire tape production winding process requires close monitoring and control of various parameters to ensure that the tape products that meet quality standards and customer needs are produced.

[0003] For example, a Chinese utility model patent (CN219688853U) discloses an adjustable winding device for producing transparent tape, which records: "A plurality of first sleeves are fixed on the toothed disc in a circular shape; a first slide rod is slidably arranged in the first sleeve; the utility model effectively prevents the roll core from sliding during winding and affecting its production quality, and effectively prevents the roll core from being stretched and deformed." It also records: "The roll core is fixed by three adjustable clamping plates. Since most of the roll cores are made of paper, there may be insufficient tension or excessive tension. When the tension is insufficient, the roll core may slide and fail to wind the tape. When the tension is excessive, the roll core may be unevenly wound and wrinkled." Technical problems.

[0004] In summary, it can be seen that the prior art uses the adjustment of the tensioning plate to achieve the restriction of the winding core, but this method has the following technical problems: but when the mother roll is directly inserted into the rotating shaft, it is impossible to determine whether the position of the mother roll is flush with the sub-roll, and as the winding proceeds, the movement between the components may cause the position of the mother roll to shake, and then cause wrinkles in the winding, affecting the final winding effect. For this reason, the present application proposes an adjustable winding device to provide a new technical solution to solve the technical problems mentioned in the above patents.

After that, as the limiting plate descends, the position of the mother-child roll can be restricted to avoid the shaking of the mother roll during the winding process, which causes wrinkles in the winding. The lifting method can make the device adapt to the processing of mother-child rolls of various lengths, thereby improving the applicability of the device.
