Description

Technical Field

[0001] The utility model relates to the technical field of production equipment, in particular to a PE heat shrink film rolling device. Background Art

[0002] PE heat shrink film is a surface protective film that can be used to wrap around goods, minimizing moisture damage to packaging caused by rain and other factors. PE heat shrink film is an industrial packaging film product characterized by high tensile strength, high elongation, good self-adhesion, and high transparency. It can be used for both manual and machine wrapping, and is widely used for the centralized packaging of various goods. PE heat shrink film is primarily extruded from a blend of several different grades of polyethylene resin. It is puncture-resistant, extremely strong, and high-performance. It is used to wrap goods stacked on pallets, providing a more stable and neat packaging and enhanced waterproofing. PE heat shrink film roll-up devices roll the finished PE heat shrink film onto paper rolls for easy transportation and use. However, existing roll-up devices require manual removal and installation, and lack the ability to automatically and quickly replace rolled rolls or replace empty rolls. This production method not only wastes labor but also slows production, significantly reducing efficiency. Utility Model Content

The movement of the third transmission belt 19 drives the transmission shaft fixedly connected to the other end of the third transmission belt 19 to rotate. The rotation of the transmission shaft 20 drives the fixed block 17 fixedly connected to the transmission shaft 20 to rotate, thereby providing rotational force for the film roll assembly.

The movement of the fourth transmission belt 22 drives the rotating shaft 23 fixedly connected to the other end of the fourth transmission belt 22 to rotate. The rotation of the rotating shaft 23 drives the rotating cylinder 3 fixedly connected to the rotating shaft 23 to rotate. The limiting bracket 15 that is slidably connected to the rotating cylinder 3 by the rotating belt of the rotating cylinder 3 rotates, so that the fixed column 16 that is rollingly connected to the limiting bracket 15 can rotate and thus escape from the restriction range of the limiting column 9.

[0087] Working principle: Refer to Figures 1 to 5, start the third drive motor 18, and while the output shaft of the third drive motor 18 rotates, it drives the third transmission belt 19 fixedly connected to the output shaft of the third drive motor 18 to move. The movement of the third transmission belt 19 drives the transmission shaft fixedly connected to the other end of the third transmission belt 19 to rotate. The rotation of the transmission shaft 20 drives the fixed block 17 fixedly connected to the transmission shaft 20 to rotate. The rotation of the fixed block 17 drives the fixed column 16 fixedly connected to the fixed block 17 to rotate, thereby performing the film rolling work. When the work is completed, the third drive motor 18 is turned off, and the first drive motor 4 is started. The output shaft of the first drive motor 4 rotates while driving the first transmission belt 5 fixedly connected to the output shaft of the first drive motor 4 to move. The movement of the first transmission belt 5 drives the screw rod 7 fixedly connected to the other end of the first transmission belt 5 to rotate. The rotation of the screw rod 7 drives the first slider 8 threadedly connected to the screw rod 7 to slide outward. The outward sliding of the first slider 8 drives the limiting column 9 fixedly connected to the first slider 8 to move outward. When the limiting column 9 does not hinder the limiting bracket 15 from performing subsequent work, the first drive motor 4 is turned off, and the fourth drive motor 21 is started. The output shaft of the fourth drive motor 21 rotates while driving the fourth transmission belt 22 fixedly connected to the output shaft of the fourth drive motor 21 to move. The movement of the fourth transmission belt 22 drives the rotating shaft 23 fixedly connected to the other end of the fourth transmission belt 22 to rotate. The rotation of the rotating shaft 23 drives the The rotating cylinder 3 fixedly connected to the rotating shaft 23 rotates, and the limiting bracket 15 that is slidably connected to the rotating cylinder 3 through the rotating belt of the rotating cylinder 3 rotates. When the limiting bracket 15 rotates to the lowest position, the fourth drive motor 21 is turned off and the second drive motor 10 is started. While the output shaft of the second drive motor 10 rotates, it drives the second transmission belt 11 fixedly connected to the output shaft of the second drive motor 10 to move. The movement of the second transmission belt 11 drives the bidirectional threaded rod 13 fixedly connected to the other end of the second transmission belt 11 to rotate. The rotation of the bidirectional threaded rod 13 drives the second slider 14 threadedly connected to the bidirectional threaded rod 13 to slide outward, and the outward sliding of the second slider 14 drives the limiting bracket 15 fixedly connected to the second slider 14 to slide outward. The clamping of the limiting bracket 15 is lost, and the film winding drum 2 and the fixed column 16 with the rolled film fall together, thereby realizing that the PE heat shrink film winding device automatically and quickly unloads the rolled film.
