AI Technical Summary
Existing stretch film slitting and rewinding machines require manual operation when fixing the rewinding core, which results in large positional errors and inconvenience in handling. Furthermore, the insertion method can easily lead to wear or detachment of the stretch film.
The system uses a stop block and a grooved cylinder to be inserted and fixed to the rewinding shaft. Automatic positioning is achieved by using a plug to engage the fixing groove. The combination of a limit strip and a limit groove ensures that the stretch film is rolled up neatly. The stop block prevents the rewinding shaft from rotating to prevent the stretch film from being worn or falling off.
It enables rapid and accurate positioning and convenient retrieval of the rewound core, avoiding wear and tear and detachment of the stretch film, and ensuring the neatness of the stretch film winding.
