The connecting shaft 16 inside the side, the other end of which is fixedly connected to a film-collecting fixing square tube 17, and both ends of the film-collecting fixing square tube 17 are connected to a film-collecting shaft 18; the fuse mechanism 8 is composed of a fuse fixing shaft 19 and rocker arms 20 fixed at both ends, and a fuse wire 21 and an electrostatic rod 22 are connected between the rocker arms 20; the feeding mechanism 5 is located above the feeding belt channel 10 and is provided with a feeding push plate 23 pushed toward the film-collecting mechanism 7, and the other end of the feeding push plate 23 is connected to a feeding push cylinder 24 for controlling the movement; the unloading mechanism 9 is located on one side of the right bracket 2 and is provided with a unloading push plate 25 extending to the film-collecting shaft 18 and connected to one end of the film-collecting fixing square tube 17, and the other end of the unloading push plate 25 is connected to a unloading push cylinder 26 for controlling the movement; the right bracket 2 is equipped with a lifting cylinder 27 for simultaneously controlling the lifting and lowering of the feeding belt channel 10 and the unloading belt channel 11.

[0033] The film-raising mechanism 12 includes cantilevers 28 fixed on both sides of the left bracket 1, and the cantilevers 28 are respectively connected with a rotating shaft 29 and an inflatable shaft 30 located at both ends of the cantilever 28. The inner side of the left bracket 1 is also equipped with a film-raising cylinder 31 for pulling the cantilever 28 up and down. Manually, only the inflatable shaft 30 loaded with materials is placed on the cantilever 28, and then the inflatable shaft 30 is driven to rise to a specified height through the traction force of the film-raising cylinder 31.

[0034] The cutter film-cutting mechanism 13 is provided with a tool holder auxiliary shaft 32 fixed on both sides of the left bracket 1, and the tool holder auxiliary shaft 32 is evenly distributed with a plurality of tool holders 34 with blades 33. The tool holder 34 is also equipped with an adjustment handle 35. The tool holder 34 can be appropriately adjusted to different positions on the tool holder auxiliary shaft 32 and fixed by the adjustment handle 35. It can be flexibly adjusted to cut films of different sizes.

[0035] The rotating mechanism 6 also includes a tightening cylinder 36 for controlling the movement of the rubber-coated shaft 15. The left bracket 1 is equipped with a three-phase asynchronous motor 37 for controlling the rotation of the driving shaft 14. After the film is cut, it passes through the rubber-coated shaft 15 and the driving shaft 14 in turn. The tightening cylinder 36 pushes the rubber-coated shaft 15 toward the driving shaft 14, so that the film is in contact with the two shafts at the same time to maintain flatness.

[0036] The left bracket 1 is equipped with a micro reduction motor 38 for controlling the rotation of the film collecting mechanism 7. The micro reduction motor 38 drives the film collecting shafts 18 at both ends to exchange positions, so that the film collecting shafts 18 at both ends can simultaneously complete the work of tube entry and film collection, and the flipping angle of the film collecting shafts 18 at both ends is 180 degrees.

[0037] The fusing mechanism 8 is also provided with a fusing rotating cylinder 39 connected to one side of the fusing fixed shaft 19 and controlling the shaking. The fusing rotating cylinder 39 drives the rocking arm 20 to make the fuse wire 21 reach a specified height and fuse the film. The static electricity on the electrostatic rod 22 blows the film toward and adsorbs it on the receiving tube.

[0038] The right bracket 2 is provided with upper tube mechanisms 40 on both sides that are respectively connected to the upper and lower feeding belt channels 10. An inclined material plate 41 is provided inside the upper tube mechanism 40. The material plate 41 is controlled to rise and be delivered forward by the bottom upper tube cylinder (not marked). The material is manually placed in the upper tube mechanism 40 and is leveled in order by the material plate 41. After the inner material plate 41 rises, it is delivered upward step by step due to its inward inclination until it enters the feeding belt channel 10.

[0039] Compared with the traditional technology, this technical solution adopts double workstations distributed up and down to jointly complete the automatic slitting and rewinding of the film. Compared with the operation of a single workstation, it greatly improves the overall production speed and achieves a greater output in the same time. The film collection mechanism 7 can better complete the film collection process with the assistance of the rotating mechanism 6 and the fusing mechanism 8. When the film collection is converted to each other, the fusing mechanism 8 flattens and fuses and effectively prevents static electricity. The rotating mechanism 6 strengthens the fit of the film to prevent wrinkles in the film. The tube loading mechanism 40 automatically loads the tube throughout the process without manual operation. In addition, the film size is flexibly adjustable, the overall degree of automation is high, and the practicality is stronger. Specific embodiment:

[0041] When in use, pipes of the same size are manually loaded into the upper pipe mechanism 40, and the pipes on both sides roll forward in the upper pipe mechanism 40 with the help of the inclined material plate 41. The inner material plate 41 is controlled by the upper pipe cylinder (not marked) to rise, and the internal pipes are gradually delivered forward until they enter the progressive feeding belt channel 10. The tightening cylinder 36 pushes the rubber-coated shaft 15 toward the active shaft 14, and the feeding push cylinder 24 in the feeding mechanism 5 pushes the feeding push plate 23 to push the pipes limited on the feeding belt channel 10 onto the film collecting shaft 18.

[0042] The film material is manually loaded onto the inflatable shaft 30 and placed on the cantilever 28. The upper film cylinder 31 drives the cantilever 28 to rise so that the inflatable shaft 30 rises to a specified height. The film material on the inflatable shaft 30 passes through the cutter film separation mechanism 13. When the film material passes through the specified point, it is cut into several parts by the internal blade 33. The lengths of the parts are the same as the length of the tube material. After the film is cut, it is transmitted to the rotating mechanism 6. In the rotating mechanism 6, it first passes through the rubber-coated shaft 15 and then the driving shaft 14, so that the film material runs at a uniform and stable speed. The three-phase asynchronous motor 37 drives the driving shaft 14 to rotate and drives the film material forward at the same time.

[0043] The material tube is transported to the film collecting shaft 18 through the feeding belt channel 10. When the film collecting shaft 18 receives the specified quantity, the micro-reduction motor 38 drives the film collecting shafts 18 on both sides to exchange positions, and the material tube continues to enter the other film collecting shaft 18 until it is full. When they exchange positions, the film material will enter one of the film collecting shafts 18 through the rotating mechanism 6 for collection until the specified weight is received. The three-phase asynchronous motor 37 stops running, and the micro-reduction motor 38 drives the film collecting shaft 18 to flip 180 degrees to horizontal. During the flipping process, the fuse 21 of the fuse mechanism 8 will rotate and rise, contact the film, and cause the film to fuse.

[0044] After the fuse 21 melts the film material, the lifting cylinder 27 starts to rise and raises the loading belt channel 10 and the unloading belt channel 11 by 200mm. The unloading push cylinder 26 in the unloading mechanism 9 controls the unloading push plate 25 to push the material tube that has collected the film into the unloading belt channel 11 for unloading. After unloading is completed, the lifting cylinder 27 controls the descent to restore the loading belt channel 10 and the unloading belt channel 11 to their original points.

[0045] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
