[0001] The utility model relates to the technical field of large-diameter PE pipeline production and packaging, in particular to a pipeline port winding sealing film plugging device with an exhaust function. Background Art

[0002] During the automatic production and packaging process, large-diameter PE pipes need to be wrapped with a layer of film and sealed at the end to prevent dust and flying insects from entering the pipe during the subsequent transportation and storage process, making the inside of the pipe unclean and affecting the subsequent welding and installation of the pipe. And after the port is automatically wrapped and sealed, in order to ensure the beauty of the port, the wrapped and sealed sealing film needs to be inserted into the pipe. Since the pipe port wrapping is carried out online after the pipe is extruded, produced and cut, the pipe is still at a certain temperature at this time, and there is a large amount of high-temperature gas inside. The pipe is inflated, and forced insertion can easily break the entire sealing film, thereby making the subsequent dust and insect prevention functions ineffective. Utility Model Content

[0019] The membrane-poking mechanism includes a membrane-poking cylinder fixing frame 4, a membrane-poking cylinder 5, a membrane-poking head 6, a hollow air-conducting membrane-poking needle 7 and a vacuum generator 9. The telescopic rod of the membrane-poking cylinder 5 is connected to the membrane-poking head 6. The membrane-poking head 6 is provided with a hollow air-conducting membrane-poking needle 7. The interior of the hollow air-conducting membrane-poking needle 7 adopts a hollow design for gas transportation. The membrane-poking head 6 is provided with a PU air pipe quick connector 8. The PU air pipe quick connector 8 is connected to the vacuum generator 9 through a PU spring air pipe. The PU air pipe quick connector 8 is connected to the hollow air-conducting membrane-poking needle 7. The vacuum generator 9 is fixed to the overall mechanism fixing plate 3 by two hexagon socket screws.

[0020] The film-piercing cylinder 5 is fixed on the film-piercing cylinder fixing frame 4, and the film-piercing cylinder fixing frame 4 is connected to the movable block of the lifting cylinder 10. The film-piercing cylinder fixing frame 4 is made of a thickened steel plate that is bent, welded, and punched, and the film-piercing cylinder fixing frame 4 is fixedly connected to the movable block of the lifting cylinder 10 by four hexagonal screws.

[0021] The right side of the film-poking cylinder 5 and the film-poking cylinder fixing frame 4 are locked and fixed by threads and a nut, and the left side is locked and fixed by the film-poking cylinder fixing frame 4, the film-poking cylinder auxiliary fixing plate 11 and two groups of bolts and nuts, so that the film-poking cylinder 5 is fixed on the film-poking cylinder fixing frame 4 more firmly, ensuring that the film-poking cylinder 5 does not swing when working.

[0022] The membrane-piercing head 6 is made of a polytetrafluoroethylene block by cutting, punching and grinding. A threaded hole is respectively opened on the left and right sides and the upper left side of the membrane-piercing head 6, wherein the threaded hole on the upper left side is connected with the threaded hole on the right side. The membrane-piercing head 6 is fixedly connected with the telescopic rod of the membrane-piercing cylinder 5 through the threaded hole on the left side and is locked twice through a nut. The hollow air-conducting membrane-piercing needle 7 is connected with the threaded hole on the right side of the membrane-piercing head 6 through a threaded connection. The PU air pipe quick socket 8 is fixed with the threaded hole on the upper left side of the membrane-piercing head 6 through a threaded connection, and the PU air pipe quick socket 8 is connected with the vacuum port of the vacuum generator 9 through a PU spring air pipe.

[0023] The specific working process of the utility model device in the production process is as follows: first, two utility model devices are fixed to the winding devices at both ends of the pipe through the overall mechanism fixing plate 3 and the hexagon socket screws. The two devices are mirror-set and located at both ends of the pipe respectively, and then the devices are started. When the winding equipment at both ends of the pipe wraps the winding film around the two ends of the large-diameter PE pipe 1 and completes the sealing to form a wound and sealed sealing film 2, the lifting cylinder 10 works to drive the film-piercing cylinder fixing frame 4 and the film-piercing cylinder 5 fixed thereon to move downward. At this time, the hollow air-conducting film-piercing needle 7 is just located at the center of the large-diameter PE pipe 1. Then the film-piercing cylinder 5 works to drive the film-piercing head 6 and the hollow air-conducting film-piercing needle 7 thereon to move right. The polytetrafluoroethylene film-piercing head 6 pokes the wound and sealed sealing film 2 to the right into the interior of the large-diameter PE pipe 1. At the same time, the hollow air-conducting film-piercing needle 7 pierces a small hole in the wound and sealed sealing film 2. At the same time, the vacuum generator 9 generates a vacuum negative pressure to draw out the gas inside the large-diameter PE pipe 1 along the hollow air-conducting film-piercing needle 7, the film-piercing head 6, and the PU spring air pipe to avoid normal film-piercing due to inflation. After the film is poked, the vacuum generator 9 stops running, the film poking cylinder 5 drives the polytetrafluoroethylene film poking head 6 to return to its original position, and finally the lifting cylinder 10 moves up and returns to its original position to make way for the next winding action. During the overall film poking process, the mirror image device on the other side performs the same action in a mirror image manner to poke the wrapped and sealed sealing film into the port on the other side of the large-diameter PE pipe 1. At this time, the wrapped and sealed sealing films at both ends of the large-diameter PE pipe 1 have been completed, and the pipes with completed poking at both ends are grabbed by the next automatic grabbing mechanism, and then the device waits for the port of the next large-diameter PE pipe 2 to be wrapped and sealed.

[0024] The utility model has novel design, reasonable conception, simple operation and convenient use. During the plugging process, a small hole is poked in the sealing film wrapped and sealed at both ends of the large-diameter PE pipe to discharge part of the internal gas in time, so as to prevent the sealing film from being unable to be plugged in due to bulging, and to avoid the entire sealing film being broken due to forced plugging due to bulging inside the pipe, thereby making the subsequent dust and insect prevention functions invalid. Moreover, the small hole of the plugging can ensure that dust and flying insects do not enter, so that the pipe will not be burst due to thermal expansion of gas during the subsequent stacking process in a high-temperature environment.

[0025] The above description is only a preferred implementation mode of the utility model, and does not impose any form of limitation on the utility model. Any simple modification, equivalent change or modification made to the above embodiments based on the technical principle of the utility model still falls within the scope of the technical solution of the utility model.
