Description

Technical Field

[0001] The utility model relates to the technical field of rewinding machines, in particular to a self-adhesive striping rewinding machine. Background Art

[0002] Self-adhesive stickers are a type of sticky sticker material that is usually made up of a backing paper, an adhesive, and a surface coating. It is also called self-adhesive stickers or tapes because its adhesive can adhere to a variety of surfaces without external pressure.

[0003] The self-adhesive paper stripping and rewinding machine is a device used to cut and rewind the self-adhesive paper roll into strips. The paper roll placement device loads and supports the self-adhesive paper roll to be cut. The strip cutting system is used to cut the self-adhesive paper roll into multiple narrow strips. The control system is responsible for controlling the electronic or computer system of the entire machine operation, such as by setting parameters such as cutting width, length and tension. The rewinding device rewinds the strip-cut paper roll into a roll or flat plate according to the required specifications. The tension control system is used to ensure that the tension of the paper roll is stable during the entire cutting and winding process to prevent the paper roll from loosening or being over-tightened.

[0004] During the use of the equipment, the self-adhesive tape can be effectively cut and wound, but the existing equipment does not have the problem of re-adjusting the dislocation of the self-adhesive winding. The dislocation of the winding after the self-adhesive tape is cut requires stopping the machine, flipping the winding device, and re-tightening the winding. During this process, manual support is required for the self-adhesive tape at the reverse winding position, which may cause contamination and damage of the self-adhesive tape, and the winding equipment has a tight structure, so manual support poses a safety hazard. For this reason, we propose a self-adhesive striping and rewinding machine to solve the existing problem. Utility Model Content
