AI Technical Summary
The existing winding machines have fixed winding roller diameters, which cannot adapt to sleeves with different inner diameters, resulting in poor equipment compatibility and an inability to quickly respond to changes in the production line.
A biodegradable plastic film winding device was designed. Through a support base, a drive mechanism, a winding roller, and an adjustment mechanism, the roller diameter can be adaptively adjusted to accommodate plastic film cores with different inner diameters.
It enables adaptive adjustment of the winding roll diameter to accommodate sleeves with different inner diameters, improving equipment compatibility and response speed, and saving costs.
