A rotating shaft is passed through the packaging film roll, and the rotating shaft is horizontally supported by the two placement racks.

[0035] A cutting seat 4 is provided on one side of the packaging rack 2. The cutting seat 4 is installed on a rod body on one side of the packaging rack 2 or on an auxiliary rod body for installing the rotating rack 5. The installation position of the cutting seat 4 is fixed. A cutting cylinder 41 is horizontally installed on the cutting seat 4. An electric cutter 42 for cutting the packaging film is installed on the end of the cutting cylinder 41 facing the packaging rack 2. The electric cutter 42 is a circuit wire. The circuit wire is heated after being energized. The cutting cylinder 41 drives the energized circuit wire to cut off the packaging film; a positioning cylinder 43 is installed at the bottom of the cutting seat 4. The positioning cylinder 43 is parallel to the cutting cylinder 41. An electromagnet 44 is installed on the end of the cutting seat 4 facing the packaging rack 2. The electromagnet 44 has the ability to absorb metal after being energized. Magnetism disappears after power is cut off. A guide cap 45 made of metal is arranged directly above the placement seat 13 through an electromagnet 44. The top of the guide cap 45 is conical, the inside of the guide cap 45 is hollow and the bottom is open. The guide cap 45 can be sleeved on the top of the gypsum line to be packaged. After the electromagnet 44 adsorbs the guide cap 45, the top of the gypsum line is positioned by extending and retracting the positioning cylinder 43. When the electromagnet 44 is powered off, the exhaust fan can adsorb the guide cap 45 through the two film-wrapping ends 32. During packaging, the guide cap 45 is located at the open end of the packaging bag. During the film-wrapping process, the guide cap 45 is located in the packaging bag and covers the top of the gypsum line, so that the packaging film can be stretched open during the film-wrapping.

[0036] When the device is used to package the gypsum wire by a vertical film packaging method for gypsum wire, firstly, multiple gypsum wires to be packaged are placed on the placement seat 13. After the multiple gypsum wires are neatly arranged, their bottom ends are supported on the placement seat 13, and the middle part is located between two swing rods 14 of the multiple swing material parts. The multiple gypsum wires are vertically placed through the support of the multiple rollers 16 of the swing material parts. At this time, the film assembly 3 is located at the top of the gypsum wire, the two film ends 32 are in a position close to each other, and the guide cap 45 is located in the packaging The film is loaded and adsorbed by the exhaust fan through the two film sleeve ends 32. The film sleeve motor drives the film sleeve seat 31 to move downward. During the downward movement, the guide cap 45 and the bottom end of the packaging film are synchronously moved downward. When the guide cap 45 is buckled on the top of the gypsum line, the film sleeve seat 31 continues to move downward and only drives the packaging film to move downward. The guide cap 45 buckled on the top of the gypsum line is used to open the packaging film. When the film sleeve end 32 passes through the swing material part, it will toggle the swing rod 14. After the film sleeve end 32 leaves the swing material part, the swing rod 14 is restored under the action of the spring 15. At this time, the plaster line between the two swing rods 14 has been put in the packaging film. When the film sleeve seat 31 moves to the bottom, the two film sleeve ends 32 are lower than the placement seat 13, the positioning cylinder 43 extends and the electromagnet 44 is energized to adsorb the guide cap 45, and then the two horizontal cylinders 33 on the film sleeve seat 31 act synchronously to drive the two film sleeve ends 32 away from each other, and the film sleeve motor drives the film sleeve seat 31 to move up. When the film sleeve seat 31 moves to the height of the guide cap 45, the two film sleeve ends 32 are close to each other. The exhaust fan uses the two film ends 32 to absorb the guide cap 45, and at the same time the electromagnet 44 is powered off, the positioning cylinder 43 shrinks, and the film seat 31 continues to rise to drive the guide cap 45 to move above the gypsum line. Then the cutting cylinder 41 extends to drive the energized electric cutter 42 to pass over the gypsum line, cut off the packaging film, and then the cutting cylinder 41 is reset. At this point, the film of the gypsum line is completed. After blowing hot air to the surface of the gypsum line after the film is wrapped, the packaging film shrinks due to the heat, that is, it shrinks to the surface of the gypsum line, and the packaging work is completed.

[0037] Furthermore, there are multiple placement components 1, and the multiple placement components 1 are all installed on the rotating frame 5 and are evenly spaced along the circumferential direction with the central axis of the rotating frame 5 as the center. The rotating frame 5 can be rotatably installed on one side of the packaging frame 2. The rotating frame 5 is driven to rotate by a rotating motor, and the rotating motor is a servo motor. The angle of each rotation of the rotating frame 5 can be adjusted according to the number of placement components 1, so that the placement seats 13 of the multiple placement components 1 can be located below the two sleeve film ends 32 in sequence. The placement components 1 are preferably 4, and at this time, the angle of each rotation of the rotating frame 5 is 90° or an integer multiple of 90°. A horizontal crossbar is fixed on the film sleeve seat 31, and a hot air box 34 is installed on the crossbar. The hot air box 34 moves synchronously with the film sleeve seat 31. The hot air box 34 is hollow inside and has multiple heating tubes installed inside. A heat sealing groove is provided on the side of the hot air box 34 facing the rotation center of the rotating frame 5. The hot air box 34 is concave in top view. The heat sealing groove is located on the side of the hot air box 34 facing the rotating frame 5. There are multiple air holes on the groove wall of the heat sealing groove. An induced draft fan is installed on the hot air box 34.
