Description

Technical Field

[0001] The utility model belongs to the technical field of adhesive tape winding devices, in particular to a lifting type roll changing mechanism. Background Art

[0002] The tape is composed of two parts: a base material and an adhesive. The adhesive is attached to the surface of the base material. When in use, two or more unconnected objects are connected together through the adhesive.

[0003] The tape needs to be rolled and formed during the production process. In the specific implementation process, the base material needs to be rolled onto the receiving roller first, and then one end of it is extended into the interface of the roll-changing mechanism, and finally the tape is pulled out at the interface as needed. However, when the rolled tape needs to be replaced, since the upper and lower plates of the roll-changing mechanism are fixedly set and the gap is small, manual threading is time-consuming and labor-intensive, and the threading efficiency is low, which affects the subsequent processing progress and cannot meet the fast-paced production requirements.
