[0002] Stretch film is a plastic film used for packaging and protecting items. It is usually made of polyethylene (PE) material and has good elasticity and strength. Stretch film can tightly wrap products. By using stretch film to tightly wrap items, it can prevent dust, moisture, and damage, and is commonly used in the logistics and warehousing processes.
[0003] When stretch film is used to package items, the width of the stretch film fixed on the reel is limited. When the item has a large volume, it may cause some positions on the surface of the item to not be fully wrapped with the film. People need to adjust the placement position of the item multiple times and repeatedly wrap the film around the outer surface of the item. This not only affects the overall wrapping efficiency of the item but also causes a certain waste due to the repeated wrapping of the film, increasing the labor intensity during people's operation.
[0004] In view of the above-related technologies, the inventor believes that there is a defect that the item is too large in volume to be suitable for the fixed-width film when winding the stretch film. Therefore, a stretch film packaging device is proposed to solve the above problems. Utility Model Content

[0019] The following further elaborates on this application Figures 1 - 4 in conjunction with the attached drawings.
[0020] An embodiment of this application discloses a winding film packaging device. Refer to Figures 1 - 4 A winding film packaging device includes a packaging bracket 1. One side edge at the top of the packaging bracket 1 is fixedly installed with a fixed bracket 2. A groove 3 is opened at the bottom of one side of the fixed bracket 2. A first packaging film 4 is rotatably installed in the groove 3 through a reel. On the other side of the fixed bracket 2, a guide rod 5 is fixedly installed. A movable sleeve 6 is movably installed on the outer surface of the guide rod 5. On one side of the outer surface of the movable sleeve 6, a support frame 8 is fixedly connected. A second packaging film 9 is rotatably installed in the support frame 8 through a reel. On the other side of the outer surface of the movable sleeve 6, a rack plate 7 is fixedly installed. At the middle positions of the front and rear ends of the fixed bracket 2, fixed plates 10 are welded. A gear 11 is rotatably installed between the two fixed plates 10. One side of the rack plate 7 movably approaches the outer surface of the gear 11. The rack plate 7 and the gear 11 are meshed with each other. One end of the gear 11 extends outside the fixed plate 10 and is installed with a knob 12. A limiting mechanism is also provided on the outer surface of the fixed plate 10 for limiting and fixing the rotating gear 11.
[0021] By placing an object on the upper surface of the object placing plate 21, rotating the knob 12 drives the gear 11 to rotate, causing the gear 11 to drive the rack plate 7 to move up and down, and further causing the movable sleeve 6 to move up and down along the outer surface of the guide rod 5, adjusting the overall placement height of the second packaging film 9 inside the support frame 8, and adjusting the overall winding width after the combination of the second packaging film 9 and the first packaging film 4, so that one ends of the first packaging film 4 and the second packaging film 9 are placed on the outer surface of the object, and the rotation of the object drives the first packaging film 4 and the second packaging film 9 to wind and package it, reflecting the overall width adjustment effect after the combination of the first packaging film 4 and the second packaging film 9.
[0022] Refer to Figure 3 and Figure 4, the limiting mechanism includes a connecting plate 13. The connecting plate 13 is fixedly installed at the middle of the other end of the gear 11 and extends outside the fixing plate 10. Limiting rods 14 are welded equidistantly on the outer surface of the connecting plate 13. A limiting sleeve frame 15 is fixedly installed on the outer surface of the fixing plate 10 near the connecting plate 13. A T-shaped movable rod 16 is movably installed inside the limiting sleeve frame 15. A spring 17 is sleeved on the outer surface of the T-shaped movable rod 16 inside the limiting sleeve frame 15. One end of the T-shaped movable rod 16 extends outside the limiting sleeve frame 15 and is welded with a limiting plate 18. A number of limiting holes 19 are opened at one end of the limiting plate 18. The number of the limiting rods 14 is the same as that of the limiting holes 19 and they are aligned with each other. One side of the outer surface of the limiting rod 14 is inside the limiting hole 19, and the limiting rod 14 and the limiting hole 19 are fitted with each other.
[0023] By pulling the limiting plate 18, the T-shaped movable rod 16 moves along the inside of the limiting sleeve frame 15, canceling the limitation of the limiting plate 18 on the limiting rod 14, so that the gear 11 can rotate normally. After the adjustment is completed, the T-shaped movable rod 16 moves inside the limiting sleeve frame 15 under the reset of the spring 17, and then the limiting plate 18 movably clamps on the outer surface of the limiting rod 14, limiting and fixing the rotated and adjusted gear 11, and then keeping the second packaging film 9 fixed at a certain height, reflecting the limiting and fixing effect of the limiting plate 18 on the gear 11 at different angles.
[0024] Refer to Figure 1 and Figure 2 , a brake motor 20 is arranged at a position inside the packaging bracket 1 far from the fixing frame 2. The output end on the upper surface of the brake motor 20 extends above the packaging bracket 1 and is installed with a placing plate 21. By starting the brake motor 20, the items on the placing plate 21 are driven to rotate, and then the first packaging film 4 and the second packaging film 9 are driven to wind and package the items, so that the first packaging film 4 and the second packaging film 9 are evenly wound on the outer surface of the items, reflecting the overall packaging effect of the items.
[0025] The implementation principle of a winding film packaging device according to an embodiment of the present application is as follows: Place an item on the upper surface of the placing plate 21, rotate the knob 12 to drive the gear 11 to rotate, so that the gear 11 drives the rack plate 7 to move up and down, and then the movable sleeve 6 moves up and down along the outer surface of the guide rod 5, adjusting the overall placement height of the second packaging film 9 inside the support frame 8, and adjusting the overall winding width after the combination of the second packaging film 9 and the first packaging film 4. At the same time, pull the limiting plate 18 to make the T-shaped movable rod 16 move inside the limiting sleeve frame 15, so that the limiting plate 18 cancels the limitation on the limiting rod 14, enabling the gear 11 to rotate normally. After the adjustment is completed, the T-shaped movable rod 16 moves inside the limiting sleeve frame 15 under the reset of the spring 17, and then the limiting plate 18 is movably clamped on the outer surface of the limiting rod 14 to limit and fix the rotated and adjusted gear 11, thereby keeping the second packaging film 9 fixed at a certain height. Place one end of the first packaging film 4 and the second packaging film 9 on the outer surface of the item, and start the brake motor 20 to drive the item on the placing plate 21 to rotate. The input end of the power supply of the brake motor 20 is electrically connected to the output end of an external power supply, thereby driving the first packaging film 4 and the second packaging film 9 to wind and package the item; compared with the prior art, this solution has the effect of facilitating the winding film for items of different sizes, improving the applicability of the combination of the first packaging film 4 and the second packaging film 9 for item packaging, solving the problem of inconvenience when repeatedly adjusting the winding position due to large items, and improving the overall packaging efficiency of the item.
