Description

Technical Field

[0001] The utility model relates to the technical field of winding racks, in particular to a winding rack with a limiting structure. Background Art

[0002] Packaging has two major functions: one is to protect goods from damage and deterioration during the manufacturing, transportation, warehousing and sales processes; the other is to decorate, beautify, promote and add value to the goods. It also beautifies people's lives, meets the growing material and cultural needs of consumers, and promotes and stimulates consumption.

[0003] Publication No. CN219929132U discloses a winding mechanism for a setting machine. A winding mechanism for a setting machine comprises a cloth rolling trolley, the cloth rolling trolley comprising a base and a bracket arranged on the base, a winding roller arranged on the bracket, a driving device arranged on the bracket and used to drive the winding roller to rotate, and a roller arranged at the bottom of the base, wherein the mechanism further comprises a storage device arranged between the roller and the base and used to store the roller in the base. The beneficial effect of this application is that the roller can be stored in the base or pushed out from the base by the storage device. When the roller is stored in the base, the movement of the cloth rolling trolley caused by the winding roller winding the cloth can be reduced, thereby improving the winding efficiency. When the cloth rolling trolley needs to move, the storage device can push the roller out, thereby facilitating the movement of the cloth rolling trolley. Although the rewinding device has an automatic roller to facilitate the movement of the rewinding device, it does not have a limiting effect during the rewinding process. The wrapping paper is prone to deviate during rewinding, and manual limiting operations are required. The worker's hand may be rolled into the wrapping paper, which is not only dangerous but also time-consuming and labor-intensive, and needs to be improved. Utility Model Content
