Feeding unit for plastic film in packaging machines
The granted patent (Publication Number: US11964786B2) discloses a feeding unit designed for packaging machines used in packaging paper rolls. The feeding unit includes an unwinding unit, a cutting device, a transfer device, and a positioning device. The unwinding unit consists of motorized horizontal rollers that facilitate the unwinding of the plastic film from a reel. A cutting device is positioned downstream of the unwinding unit to incise the film transversely, allowing for the creation of sheets of predetermined length. The transfer device and positioning device both feature a specific number of drive belts on each side of the feeding unit to engage the upper and lower faces of the film effectively.
Moreover, the feeding unit incorporates independent actuators, such as electric motors, to control various components of the unit. The patent also mentions a support base for the reel with horizontal axis support rollers, connected to electric motors, to facilitate the rotation of the reel for unwinding the film. Additionally, the feeding unit includes features where the distance between the belts of certain pairs of belts varies cyclically between minimum and maximum values. Furthermore, the feeding unit is capable of producing sheets from the film with lengths ranging from 240 mm to 1100 mm, catering to different packaging requirements efficiently. Overall, the patent highlights a specialized feeding unit tailored for packaging paper rolls, offering precise control and flexibility in the packaging process.
