This utility model achieves the advantage of good applicability through the coordinated use of a motor, a first gear, a gear plate, a second gear, a drive shaft, a rotating shaft, and a rotating shaft, thereby addressing the poor applicability of existing film wrapping machines for paper product packaging. The utility model can be adjusted at multiple angles without affecting the packaging effect of paper products, thereby improving paper product packaging efficiency and meeting user needs.

[0004] The film wrapping machine for paper product packaging disclosed in the aforementioned reference document has the following drawbacks: each time a paper product is wrapped with film, it is necessary to manually attach the film to the paper product before wrapping it, which is cumbersome and requires manual assistance each time. Moreover, after wrapping, the film still needs to be manually cut short, which increases the workload.

[0005] For this purpose, we have designed a film wrapping machine for paper product packaging. Utility Model Content

[0006] The technical problem solved by the utility model is to provide a film wrapping machine for paper product packaging that is highly practical, can be easily operated, and has a relatively simple structure, thereby solving the problem in the above-mentioned background technology that manual assistance is required for each film wrapping.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions: a film wrapping machine for paper product packaging, comprising a U-shaped rod, the bottom of the U-shaped rod is fixedly connected to a base plate, one side of the top of the base plate is fixedly connected to a fixed block, both sides of the top of the fixed block are provided with inclined surfaces, the surface of the inclined surfaces is provided with a slide groove, the inside of the slide groove is slidably connected to a slider, the top of the slider is fixedly connected to a fixed rod, one side of the fixed rod is fixedly connected to a rubber pad, one side of the slider is fixedly connected to a cylinder, the surface of the cylinder is movably connected to a movable ring, the bottom of the movable ring is fixedly connected to a first hydraulic rod, the bottom of the first hydraulic rod is fixedly connected to the base plate, and one side of the fixed block is slidably connected to a cutter.

[0010] Optionally, a cavity is opened inside the L-shaped rod, and a second servo motor is fixedly installed on the inner wall of the cavity. The output end of the second servo motor is spline-connected to a second transmission rod, and one end of the second transmission rod is fixedly connected to a threaded rod. The second servo motor can drive the threaded rod to rotate through the second transmission rod.

[0011] Optionally, a movable block is slidably connected to the surface of the second threaded rod, a placement plate is fixedly connected to one side of the movable block, and a first round block is fixedly connected to the surface of the placement plate.

The film is then pulled out to the middle of the two fixed rods and the first hydraulic rod is opened to push the movable ring upward to drive the slider to slide on the inclined surface of the fixed block, thereby causing the two fixed rods to rise and approach each other so that the rubber pads on their surfaces clamp the film. The first servo motor is then turned on to drive the L-shaped rod to rotate with the first transmission rod as the axis, and the second servo is then turned on. The motor drives the threaded rod to rotate through the second transmission rod, and then drives the clamped film cylinder to move from bottom to top to wrap the paper product. After wrapping the paper product several times, the first hydraulic rod is closed, and it is driven to slide down through the movable ring, so that the film is no longer clamped. At this time, the film wrapping work can still operate normally. When the film wrapping is about to be finished, the fixed rod is first clamped to hold the film, and the second hydraulic rod is opened to push the cutter to cut the film, which reduces the labor required for manual wrapping each time and improves the convenience of the device.
