As shown in fig. 1, the web sealing machine further comprises a discharging device 5, the discharging device 5 comprises a discharging frame 51, a second conveying belt 52 and a hot air blower 53, the second conveying belt 52 is installed on the discharging frame 51, and the second conveying belt 52 is driven by a fifth power source to convey towards a fixed direction. The hot air blower 53 comprises a body 531 and an air outlet pipe 532, wherein the body 531 is arranged on the discharging frame 51, and the pipe orifice of the air outlet pipe 532 is positioned below the second conveyor belt 52. The film can be made of heat shrinkage materials, the film is shrunk after being blown and baked by the hot air fan 53, the wrapping of the film on the roll 6 is more compact, and the film sealing quality is further improved.
Before operation, two rolls of film are placed on the rotating idlers 32 of the first film placing module and the second film placing module of the film feeding device 3, respectively. The web 6 enters the web film sealing machine after being rewound by the rewinding machine, and the position of the winding head of the web 6 is controlled to be changed by the winding head positioning device 1 and is driven to a proper position by the first driving belt 11, as shown in fig. 1.
At this time, the roll stock pushing device 2 pushes the roll stock 6 to the film, and at the same time, the film stock roll 7 is driven to rotate by the feeding roller 341 and is fed forward passively, and after the roll stock pushing device is pushed to a proper position, the feeding roller 341 stops feeding, and thus the film stock roll 7 stops feeding in rotation, and at the same time, the pushing die 21 is retracted, and the stock roll 6 is not shifted.
Finally, the film cutter device 4 cuts the film and bonds the head of the film produced by the cutting at the same time as the cutting, as shown in fig. 8. The film is tensioned by the film tensioning assembly 33 as shown in fig. 9. The next web 6 repeats the above process to complete the continuous film sealing of the web 6.
Thus, the film sealing operation is realized stably and continuously on the roll material 6, the production efficiency is improved, the film sealing is compact, and the film sealing quality is good.
In summary, the foregoing description is only of the preferred embodiments of the invention, and is not intended to limit the invention to the particular embodiments disclosed, but on the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the invention.
