[0030] The swing arm assembly comprises a second rotating shaft 5, a swing arm pressure rod 8, a swing arm 9 and a swing arm rotating shaft 10, as Figure 3As shown. The swing arm 9 is located between the rear main body 6 and the front main body 7. A swing arm pivot 10 is connected to the lower bearing of the swing arm 9. The swing arm pivot 10 passes through the rear main body 6, the swing arm 9, and the front main body 7 sequentially from back to front, and is movably connected to the rear main body 6 and the front main body 7. A swing arm pressure rod 8 is threaded to the top of the swing arm 9, and the swing arm pressure rod 8 can drive the swing arm 9 to move. The second pivot 3 is located above the swing arm pivot 10. The second pivot 3 passes through the rear main body 6, the swing arm 9, and the front main body 7 sequentially from back to front, and extends to the outer sides of the rear main body 6 and the front main body 7 respectively. Both the rear main body 6 and the front main body 7 have elliptical holes 14. The minor axis of the elliptical hole 14 is larger than the diameter of the second pivot 3, providing sufficient space for the second pivot 3 to move within the elliptical hole 14. Figure 4 As shown. The second rotating shaft 3 is in contact with the elliptical hole 14, the second rotating shaft 3 is connected to the swing arm 9 by a bearing, the second film-pulling wheel 5 is connected to the bearing at one end of the second rotating shaft 3 extending to the outside of the rear main body 6, and the second driven wheel 12 is connected to the bearing at one end of the second rotating shaft 3 extending to the outside of the front main body 7.

[0031] In the main assembly, the first rotating shaft 2 is located beside the second rotating shaft 3. The first rotating shaft 2 passes through the rear main body 6 and the front main body 7 from back to front and extends to the outer sides of the rear main body 6 and the front main body 7 respectively. The first rotating shaft 2 is connected to the main body 6 and the main body 7 by bearings. The first rotating shaft 2 and the second rotating shaft 3 have a symmetrical structure. The first film-pulling wheel 4 is connected to the bearing at the end of the first rotating shaft 2 extending to the outer side of the rear main body 6, and the first driven wheel 11 is connected to the bearing at the end of the first rotating shaft 2 extending to the outer side of the front main body 7. Specifically, the second driven wheel 12 is located beside the first driven wheel 11, and the first driven wheel 11 and the second driven wheel 12 are meshed together.

[0032] Specifically, the second film-pulling roller 5 is located beside the first film-pulling roller 4.

[0033] The motor 1 is located on one side of the main body component. Specifically, the motor 1 is located on the outside of the front main body component 7. The output shaft of the motor 1 is connected to the drive wheel 13 by a bearing. The motor 1 can drive the drive wheel 13 to rotate. The drive wheel 13 is fixedly installed on the outside of the front main body component 7. The drive wheel 13 is located below the first driven wheel 11. The drive wheel 13 and the first driven wheel 11 are meshed together.

[0034] Working principle and usage: When the operator presses down on the swing arm pressure rod 8, the second rotating shaft 3 rotates around the swing arm rotating shaft 10, causing the swing arm 9 to change position between the rear main body 6 and the front main body 7. This further causes the second driven wheel 12 to separate from the first driven wheel 11, and the second film-pulling wheel 5 to separate from the first film-pulling wheel 4. Then, the packaging film is placed at the position where the second film-pulling wheel 5 and the first film-pulling wheel 4 are tangent. Similarly, when the swing arm pressure rod 8 is pulled up, the second rotating shaft 3 rotates in the other direction around the swing arm rotating shaft 10, causing the swing arm 9 to change position between the rear main body 6 and the front main body 7. This further causes the second driven wheel 12 to engage with the first driven wheel 11, and the second film-pulling wheel 5 to engage with the first film-pulling wheel 4. The packaging film in the middle is pressed tightly by the second film-pulling wheel 5 and the first film-pulling wheel 4. Start motor 1, which drives drive wheel 13 to rotate, which in turn drives first driven wheel 11 to rotate. First driven wheel 11 drives second driven wheel 12 to rotate, first rotating shaft 2 and second rotating shaft 3 to rotate, first film pulling wheel 4 and second film pulling wheel 5 to rotate. At this time, the compressed packaging film can be fed vertically.
