[0027] Specifically, the motor 2 is fixedly connected to one side of the winding machine 1, and there are two of them, which provide rotational force inside it. The rotating shaft 3 is movably connected to one side of the motor 2. A rotating roller 5 is fixedly connected to one side of the rotating shaft 3. The rotating roller 5 is driven by the motor 2 to rotate the rotating shaft 3. The two groups of rotating rollers 5 rotate alternately, so that the product can be packaged inside while being manufactured. The unloading rollers 4 are movably connected to the inside of the winding machine 1, and there are two of them, which fix the plastic film for easy pulling.

[0028] Specifically, the fixing frame 6 is fixedly connected to one side of the winding machine 1 to facilitate the fixing of other parts. The upper end of the fixing frame 6 is fixedly connected to a cylinder 7, the lower end of the cylinder 7 is fixedly connected to a connecting rod 8, and the lower end of the connecting rod 8 is fixedly connected to a cutting blade 9. The cutting blade 9 pushes the connecting rod 8 through the cylinder 7 to cut. The plastic film is stretched to a specified length and cut automatically, which saves manual labor and also reduces material consumption.

[0029] Specifically, the hot press 10 is fixedly connected to one end of the fixed frame 6, and a first hydraulic cylinder 12 is fixedly connected to the upper end thereof, a connecting rod 8 is fixedly connected to the lower end of the first hydraulic cylinder 12, and a pressing plate 11 is fixedly connected to the lower end of the connecting rod 8. The pressing plate 11 pushes the connecting rod 8 downward through the first hydraulic cylinder 12 to make the seal tighter, and a heating pad 13 is fixedly connected to the lower end of the pressing plate 11 to heat the plastic film, making it easier to bond after melting.

[0030] Specifically, the heating block 14 is movably connected to one side of the heating pad 13, which is pressed down by the upper cylinder 7 to reserve a position for internal inflation. At the same time, the hole is sealed after the inflation is completed. The air pipe 15 is fixedly connected to one side of the fan 16, and the fan 16 is fixedly connected to the upper end of the fixed plate 17. The fan 16 inflates through the inside of the air pipe 15, thereby improving its inflation efficiency. The cylinder 7 is fixedly connected to one side of the fixed plate 17, which is contracted by the connecting rod 8 to facilitate the extraction of the air pipe 15 after inflation and bond it through the heating block 14.

[0031] Specifically, the load-bearing plate 18 is fixedly connected to the lower end of the pressure plate 11, and is equal in size to the upper pressure plate 11, making it more stable while being adhered. The second hydraulic cylinder 19 is fixedly connected to the lower end of the load-bearing plate 18. A cutting groove 20 is provided at the upper end of the load-bearing plate 18. The outer diameter of the cutting groove 20 matches the inner diameter of the upper heating pad 13 to ensure stability during cutting. The cutting groove 20 is pushed upward by the second hydraulic cylinder 19 to manufacture a large number of parts at one time, which greatly improves production efficiency.

[0032] Working principle and process: The staff fixes the plastic film on the upper end of the unloading roller 4, drives the rotating shaft 3 through the motor 2, and the rotating shaft 3 drives the rotating roller 5 to pull it. After pulling it to a certain length, the cylinder 7 pushes the cutting blade 9 through the connecting rod 8 to cut it off. The rotating roller 5 rotates alternately, cutting the bottom film first and then the upper film. The staff puts the plastic film on the load-bearing plate 18 stably, starts the hot press 10, and the upper pressure plate 11 pushes the connecting rod 8 down through the first hydraulic cylinder 12 to squeeze the plastic film. At the same time, the heating pad 13 heats the plastic film to melt it, and the cylinder 7 pushes the fixed plate 17 to press the air pipe 15 extends into the packaging bag and is inflated by the fan 16. When the air is inflated to a certain level, the cylinder 7 retracts it. The upper cylinder 7 quickly pushes down the heating block 14 to adhere the inflation port. After the adhesion is completed, the lower second hydraulic cylinder 19 pushes the cutting groove 20 through the connecting rod 8 to cut. The cutting groove 20 is surrounded by the heating pad 13. After the plastic film is fixed and cut, it is adhered in time. For example, if an object is placed in the packaging bag, the cutting groove 20 is raised before heating, the plastic film is placed on its upper end, and the object is placed through the cutting groove 20, so that the object is sealed inside. When packaging large objects, the cutting groove 20 can be stopped from rising.

[0033] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
