Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, specifically to a processing equipment for highly waterproof tearable nonwoven tape. Background Technology

[0002] In existing tape production processes, the tape to be processed is typically unwound and slit into narrow strips of the required width. These narrow strips are then rewound onto cores corresponding to their widths to form the finished tape. However, this method suffers from several drawbacks. Due to the large width of the tape, the unwinding process is prone to causing the tape to jump and become unstable during unwinding, resulting in inconsistent tension and impacting production quality. Furthermore, as the tape is processed, the outer diameter of the rewound tape gradually increases, increasing the likelihood of contact with the nearest drive roller. Additionally, current production methods struggle to combine easy-tear processing and waterproofing processes, and the tape inevitably becomes loose during these processes, affecting the overall processing outcome.

[0003] To address the shortcomings of existing technologies, people have conducted long-term explorations and proposed various solutions. For example, Chinese patent literature discloses a tape processing equipment [CN201410280350.8], which includes an unwinding core fixing shaft that gradually unwinds the tape to be processed as the unwinding core fixing shaft rotates; a conveying system for conveying the unwound tape to be processed; a slitting system for slitting the tape to be processed into several tapes with smaller widths in the opposite direction of the conveying direction; a rewinding system for rewinding the slit tapes onto the core to form finished tapes; and a rewinding protection system.

[0004] The above solution has solved to some extent the problems of unstable tape tension and easy contact between tape rollers during tape processing in the prior art. However, the solution still has many shortcomings, such as the difficulty in combining multiple processes and the tendency for loosening, which affects the processing quality.
