[0001] The utility model relates to the technical field of film material winding equipment, in particular to a machine-used stretch film winding device capable of preventing deviation. Background Art

[0002] Machine stretch film is a packaging film that can be used with large-scale stretch wrapping machines to quickly package various goods or pallets. It is usually made of PE material and is self-adhesive. The self-adhesive adhesive will not adhere to the surface of the wrapped items, but only exists on the surface of the film.

[0003] During the production process of PE machine stretch film, the extruded film needs to be quickly reeled up by a reeling device to facilitate subsequent reeling and transportation. Currently, the reeling devices used for machine stretch film are mostly similar in structure. The motor drives the paper drum to rotate at high speed. The extruded film is guided by the guide roller and reeled on the outside of the paper drum. In actual use, there are some functional deficiencies and there is room for improvement. For example, during the process of winding and guiding and conveying, a small deviation is prone to occur. If it is directly reeled up, wrinkles will be formed, affecting the final product image. It does not have the function of preventing film deviation.

The adhesive-coated paper roll is clamped by the first and second paper roll chucks 11, 13. The servo motor 12 drives the roll to rotate at high speed, allowing the film to be wound. During the winding process, a visual inspection camera 9 at the bottom of the camera mounting plate 8 captures real-time image information of the film below. If deviation is detected, the first electric cylinder 7 advances or retracts based on the feedback. The sliding plate 4 supporting the concave frame 6 then moves forward or backward along the T-shaped guide rail 3, fine-tuning the position of the paper roll and offsetting the film's deviation. During the winding process, the wrapping film pressing roller 19 presses against the bottom of the film roll. The pressure sensor 22 at the bottom of the connecting plate 20 senses the pressure from the roller frame 18 in real time. The third electric cylinder 21 retracts or extends in response to the feedback, maintaining a constant pressure value. By adjusting this pressure, the tightness of the film can be controlled. Connect the vacuum cleaner docking bayonet 27 to the industrial vacuum cleaner.
