[0023] Working principle: When using the utility model, first install the wrapping film roll on the wrapping film seat 1 on the film frame shell 17, open the protection door 12 through the handle 18 to carry out the film threading work, when the protection door 12 is opened, the proximity sensor 9 control circuit is disconnected, and the machine is kept in a shutdown state to ensure the safety of the operator. When the film is wound, the wrapping film passes through the rubber-coated roller 13, and then the double sprocket 2 and the single sprocket 3 make the wrapping film sent out at a ratio of one to two. Since the friction force on the surface of the rubber-coated roller 13 is large, the width will basically not be narrowed when the film is discharged, which can save the wrapping film to a great extent. When winding, the main sprocket 10 is driven by the DC motor 11, and the main sprocket 10 drives the rubber-coated roller 1 on the double sprocket 2 and the single sprocket 3 through the chain. 3 is used for film feeding, and is guided by the guide roller 5. When the wrapping film is sent out, the swing roller 6 presses the weight sensor 7, and the weight sensor 7 is perpendicular to the guide roller 5 and the film discharge roller 8. During the wrapping process, the speed of the DC motor 11 is continuously adjusted according to the walking speed and tension of the wrapping machine, so that the force on each corner during the wrapping is the same. When the wrapping is about to end, the film is cut by the film cutting mechanism 14. Specifically, the electromagnet 16 is extended by the current control, and the electromagnet 16 drives the film-piercing breaking shaft 15 to be pushed out of the shell 19 to pierce the wrapping film. Under the tension of the rubber-coated roller 13 at different speeds, the wrapping film is pulled off and left outside the film frame roller for convenient use next time. The guide wheel 4 is used for guiding, and the mounting plate 20 is used for installing the film cutting mechanism 14.
