Description

Technical Field

[0001] This utility model relates to the field of packaging machine technology, and more specifically, to a cam-type folding sealing device for a transparent three-dimensional film packaging machine. Background Technology

[0002] Heat shrink film packaging machines use shrink film to wrap around products or packages. After heating, the shrink film shrinks and tightly wraps the product or package, fully displaying the appearance of the item, improving its marketability, and increasing its aesthetic appeal and perceived value. Items packaged by a heat shrink machine are sealed, moisture-proof, and pollution-proof, and protect the goods from external impacts, providing a certain degree of cushioning. Especially when packaging fragile items, it can prevent the contents from scattering when the container breaks. In addition, it can reduce the possibility of products being opened or stolen.

[0003] Currently used heat shrink film packaging machines require the packaging box to be sealed before being placed in the wrapping area for heat sealing. Obviously, manually sealing the packaging box is labor-intensive. This utility model proposes a new solution to the above problems. Summary of the Invention

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0020] Example: Please refer to Figures 1 to 3 A cam-type downward folding sealing device for a transparent three-dimensional film packaging machine includes a mounting frame 1, a drive unit 2, and a downward folding angle plate 3. The drive unit 2 is mounted on the mounting frame 1. A table is bolted to the mounting frame 1, and a through groove 4 is formed on the table. The downward folding angle plate 3 is fitted into the through groove 4. A mounting plate 5 is provided on the mounting frame 1, and a mounting seat 6 is provided on the mounting plate 5. The drive unit 2 is bolted to the mounting seat 6. A swing rod 7 is connected to the output end of the drive unit 2. An adjusting rod 8 is rotatably connected to the end of the swing rod 7, and a bottom slider 9 is rotatably connected to the top of the adjusting rod 8. A bolt along the vertical direction is provided on the mounting seat 6. A vertical track 10 is connected, a bottom slider 9 is slidably connected to the vertical track 10, a top slider 11 is slidably connected to the vertical track 10, a transmission rod 12 is provided for the bottom slider 9 and the top slider 11, and the bottom slider 9 and the top slider 11 are connected by transmission rod 12. The upper thread of the transmission rod 12 is connected to a limit seat 13 and an adjusting nut 14. An adjusting seat 15 is bolted to one side of the top slider 11. The adjusting seat 15 is slidably connected to the transmission rod 12, and one end of the adjusting seat 15 is located between the limit seat 13 and the adjusting nut 14. A lower angle plate 3 is installed on the top slider 11.

[0021] The design of the lower folding plate 3, bottom slider 9, top slider 11, transmission rod 12, and adjusting seat 15 utilizes the transmission rod 12 to adjust the distance between the bottom slider 9 and the top slider 11, thereby controlling the position of the lower folding plate 3 and the vertical working space. This allows for the bending processing of different packaging boxes, making it more flexible and convenient to use, reducing manual labor intensity, and improving processing efficiency.

[0022] In this embodiment, two sets of protective wing plates 16 are provided on one side of the mounting base 6; the protective wing plates 16 are used to protect the drive part 2 on the mounting base 6, thereby reducing the impact on the drive part 2.

[0023] In this embodiment, the drive unit 2 is one of a servo motor, a stepper motor, or a rotary cylinder; the above design allows for flexible selection of the drive unit 2, making its use more flexible.

[0024] In this embodiment, a first T-shaped seat 17 is bolted to the top slider 11, and a second T-shaped seat 18 is bolted to the first T-shaped seat 17. The second T-shaped seat 18 is bolted to the lower angle plate 3. By increasing the connection point between the top slider 11 and the lower angle plate 3 through the first T-shaped seat 17 and the second T-shaped seat 18, the lower angle plate 3 can run more smoothly.

[0025] In this embodiment, a reducer 19 is provided between the drive unit 2 and the swing rod 7, and a base plate 20 is bolted to the reducer 19. The reducer 19 is bolted to the drive unit 2, and the base plate 20 is bolted to the mounting base 6.

[0026] In this embodiment, the mounting base 6 has a through hole 21; the through hole 21 on the mounting base 6 provides a mounting position.

[0027] The working process of this utility model is as follows:

[0028] The operator installs the device on the packaging machine, transports the packaging box to the processing area, and then starts the drive unit 2. The drive unit 2 drives the bottom slider 9 and the top slider 11 to swing up and down through the swing rod 7, thereby controlling the up and down movement of the lower folding plate 3. This controls the sealing edge of the packaging box. The design of the lower folding plate 3, the bottom slider 9, the top slider 11, the transmission rod 12, and the adjusting seat 15 allows the transmission rod 12 to adjust the distance between the bottom slider 9 and the top slider 11, thereby controlling the position of the lower folding plate 3 and the vertical working space. This meets the bending processing requirements of different packaging boxes, making it more flexible and convenient to use, reducing manual labor intensity, and improving processing efficiency.
