[0040] In order to realize the automatic film breaking function, a pressing mechanism 22 for pressing the wrapping film on the wrapping film frame is installed on the rack corresponding to the position of one side of the wrapping film frame 4. The pressing mechanism 22 includes a telescopic pressing plate 221, wherein a driving cylinder I 222 is installed on the rack corresponding to the position of the pressing plate, the driving end of the driving cylinder I 222 is connected to the back of the pressing plate, and the driving cylinder I 222 drives the pressing plate to extend or retract towards the wrapping film frame to press the wrapping film.

[0041] The design of the above structure has the following advantages: (1) high-efficiency automatic film cutting is realized, and production efficiency is improved. The driving cylinder one drives the top pressing plate to extend and retract, which can quickly and accurately press the wrapping film. When the film needs to be cut after packaging is completed, the top pressing plate quickly acts, preparing for the subsequent cutting of the wrapping film by the cutting knife. The driving cylinder two drives the cutting knife to extend and retract, which can timely and cleanly cut the wrapping film. This automatic film cutting process does not require manual intervention, greatly shortens the time required for film cutting, avoids the instability and inefficiency of manual operation, makes the entire packaging process more coherent, significantly improves production efficiency, and is especially suitable for large-scale and high-yield production scenarios. (2) The reliability and stability of film cutting are ensured, and the packaging quality is improved. The cooperation of the top pressing mechanism and the cutting mechanism ensures the reliability and stability of film cutting. The top pressing plate tightly presses the wrapping film, so that the wrapping film does not shift or wrinkle when being cut by the cutting knife, thereby realizing neat and clean film cutting. At the same time, the multiple tensioning rods of the tensioning mechanism provide good tensioning effect on the wrapping film, so that the wrapping film maintains appropriate tension, which is beneficial to the cutting of the wrapping film by the cutting knife, avoids the problem of incomplete film cutting or residual film caused by loose wrapping film, and effectively improves the overall quality and aesthetics of the packaging. (3) The adaptability and flexibility of the equipment are enhanced. The multiple tensioning rods of the tensioning mechanism can be adjusted according to different types and thicknesses of wrapping film to provide appropriate tensioning force. This enables the equipment to adapt to wrapping films of various specifications, expanding the application range of the equipment. Moreover, the extension and retraction of the driving cylinder one and the driving cylinder two can be accurately adjusted by the control system, which can flexibly adjust the force, time and other parameters of the top pressing and cutting according to the packaging requirements and process requirements of different products, further enhancing the adaptability and flexibility of the equipment. (4) Production costs are reduced, and maintenance is simple. The automatic film cutting function reduces the manual operation link and reduces labor costs. At the same time, since the film cutting effect is good, the waste of wrapping film is reduced, and the cost of raw materials is reduced. In addition, the top pressing mechanism, the tensioning mechanism and the cutting mechanism have relatively simple structures, and the maintenance and replacement of components such as driving cylinders are convenient, which reduces the difficulty and cost of equipment maintenance, improves the service life and running stability of the equipment.

[0042] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, the scope of the utility model is defined by the appended claims and their equivalents.
