[0029] In the film feeding assembly of the present embodiment, the film feeding mechanism can feed the film, and the film enters the film material driving mechanism after passing through the film storage mechanism. The film is stored between the first driven wheel 132 and the first tensioning wheel 14 in the film storage mechanism. The output end of the film feeding mechanism is located between the film storage mechanism and the film material driving mechanism, so that the material can be wrapped on three sides by the film after being pushed. While the material is being pushed, the film moves rapidly outward, and the first connecting plate 131 rapidly rotates in the direction close to the first tensioning wheel 14, so that the film can be rapidly extended. In the process of transporting the next material to the packaging position, the film feeding mechanism feeds the film, and under the action of the first connection and the gravity of the first driven wheel 132, the distance between the first driven wheel 132 and the first tensioning wheel 14 is gradually lengthened, so as to store the film for the next material packaging, thereby improving the packaging efficiency.

[0030] The film feeding assembly 1 includes a film feeding mechanism, a film storage mechanism and a film material driving mechanism, and the film feeding assembly 1 is connected to the support frame 2. The film feeding mechanism includes a first driving member 11, a first driving wheel 111 and a second driven wheel 112. One end of the first driving wheel 111 is connected to the output end of the first driving member 11, and the other end is rotatably connected to the support frame 2. The first driving member 11 is connected to the support frame 2, and the first driving member 11 can drive the first driving wheel 111 to rotate. The second driven wheel 112 is rotatably connected to the support frame 2, and the second driven wheel 112 is parallel to and horizontally arranged with the first driving wheel 111, and there is a gap between the second driven wheel 112 and the first driving wheel 111. The feed roll 3 is located between the first driving wheel 111 and the second driven wheel 112, and the diameter of the feed roll 3 is greater than the gap between the second driven wheel 112 and the first driving wheel 111. The first driving member 11 drives the first driving wheel 111 to rotate, thereby driving the feed roll 3 to rotate. The feed roll 3 can drive the second driven wheel 112 to rotate while rotating, so that the feed roll 3 can transport the film. Preferably, a baffle 32 connected to the support frame 2 is provided on the side of the feed roll 3 away from the film storage mechanism, and the baffle 32 can prevent the feed roll 3 from falling off between the second driven wheel 112 and the first driving wheel 111.

A take-up roll 31 is provided between the second driving wheel 121 and the third driven wheel 122. The fifth driving member 12 drives the second driving wheel 121 to rotate, thereby driving the take-up roll 31 to rotate, so that the take-up roll 31 can recycle the film. The film feeding mechanism and the film material driving mechanism form a moving path for the film.

[0031] The film storage mechanism includes a first rotating shaft 13 and two first tensioning wheels 14. The first rotating shaft 13 and the first tensioning wheel 14 are both rotatably connected to the support frame 2. A first connecting plate 131 is sleeved on the first rotating shaft 13. The first connecting plate 131 can rotate with the first rotating shaft 13. The first connecting plate 131 extends away from the film feeding assembly 1. Two first connecting plates 131 are provided and are arranged in parallel. A first driven wheel 132 is rotatably connected between the first connecting plates 131. Compared with the first tensioning wheel 14, the first connecting plate 131 is located closer to the output end of the film feeding assembly 1. The film output by the film feeding mechanism passes through the two first tensioning wheels 14 and enters the film material driving mechanism. The film between the two first tensioning wheels 14 is connected to the first driven wheel 132, so that the film between the first tensioning wheel 14 and the first driven wheel 132 is V-shaped, and the film can be stored between the first tensioning wheel 14 and the first driven wheel 132. When the material is packaged, the film is pulled quickly, and the first connecting plate 131 rotates quickly toward the first tensioning wheel 14, thereby reducing the distance between the first driven wheel 132 and the first tensioning wheel 14, so that the film can be quickly pulled to the packaging position. After packaging is completed, the first driving member 11 drives the feed roll 3 to rotate, and the feed roll 3 starts to feed out the film. At the same time, the fifth driving member 12 drives the reel 31 to recycle the film. The length of the film fed out by the feed roll 3 is greater than the length of the film recycle by the reel 31. Under the action of the gravity of the first connecting plate 131 and the first driven wheel 132, the first connecting plate 131 rotates away from the first tensioning wheel 14 until the film is tensioned, thereby completing the storage of the film. During the film storage process, the material is transported, thereby improving the overall packaging efficiency. Preferably, a connecting rod 133 is also sleeved on the first rotating shaft 13, and the extension direction of the connecting rod 133 is opposite to the extension direction of the first connecting plate 131. A counterweight 134 is provided on the connecting rod 133. The counterweight 134 can rotate with the first rotating shaft 13. The counterweight 134 is used to balance the weight of the first connecting plate 131 and the first driven wheel 132, thereby avoiding damage to the film due to the overweight of the first connecting plate 131 and the first driven wheel 132. Preferably, there are multiple first driven wheels 132 and first tensioning wheels 14, and the first driven wheels 132 are located between the first tensioning wheels 14, and compared with the first tensioning wheels 14, the first driven wheels 132 are located closer to the output end of the film feeding assembly, and the film between two adjacent first tensioning wheels 14 is connected to the first driven wheels 132, so that the moving path of the film is a plurality of connected V-shaped. By setting different numbers of first driven wheels 132 and first tensioning wheels 14, the length of the film stored in the film storage mechanism can be changed, thereby adjusting the packaging size of the film, and by changing the weight of the counterweight block 134, the film storage length can be fine-tuned, thereby making the film feeding assembly 1 of this embodiment suitable for material packaging of different sizes. Preferably, multiple first tensioning wheels 14 are arranged in a straight line and horizontally, and the film between two adjacent first tensioning wheels 14 is at an acute angle.Preferably, the film storage mechanism is arranged in parallel on both sides of the output end of the film feeding assembly 1, and a second tensioning wheel 15 rotatably connected to the support frame 2 is arranged between the film storage mechanisms. The second tensioning wheels 15 are symmetrically arranged on both sides of the output end of the film feeding assembly 1, and two second tensioning wheels 15 are arranged on each side. The two tensioning wheels are connected to the support frame 2 through a connecting seat 151. The second tensioning wheels 15 are arranged in parallel and vertically, and the film passes through the two second tensioning wheels 15 in an S shape, so that the film at the output end of the film feeding assembly 1 can be tensioned. Preferably, a plurality of third tensioning wheels 16 are also arranged between the first driving wheel 111 and the film storage mechanism. In this embodiment, two third tensioning wheels 16 rotatably connected to the support frame 2 are arranged, and the third tensioning wheel 16 is used to tension the film between the first driving wheel 111 and the film storage mechanism. Preferably, a plurality of fourth tensioning wheels 17 are also arranged between the second driving wheel 121 and the film storage mechanism, and the fourth tensioning wheel 17 is rotatably connected to the support frame 2, and the fourth tensioning wheel 17 is used to tension the film between the second driving wheel 121 and the film storage mechanism.

[0032] In another embodiment, a feed roll 3 is arranged between the second driving wheel 121 and the third driven wheel 122, and the first driving wheel 111 and the second driving wheel 121 drive the feed roll 3 to output a film connected to the output end of the film feeding assembly 1. When packaging the material, the sealing and cutting knife thermoplasticizes and cuts the film, and after the packaging is completed, the second driving wheel 121 and the first driving wheel 111 both drive the feed roll 3 to transport the film until the film storage mechanism completes the film storage. In this embodiment, the first driving wheel 111 and the second driving wheel 121 both drive the feed roll 3 to output the film, which can save materials and improve packaging efficiency.

[0033] When in use, during the material packaging process, the film is pulled quickly, and the first connecting plate 131 quickly rotates toward the first tensioning wheel 14, thereby reducing the distance between the first driven wheel 132 and the first tensioning wheel 14, and the film can be quickly pulled to the packaging position. After the packaging is completed, the first driving member 11 drives the feeding roll 3 to rotate, and the feeding roll 3 starts to feed the film. At the same time, the fifth driving member 12 drives the receiving roll 31 to recycle the film. The length of the film fed by the feeding roll 3 is greater than the length of the film recovered by the receiving roll 31. Under the action of the gravity of the first connecting plate 131 and the first driven wheel 132, the first connecting plate 131 rotates away from the first tensioning wheel 14 until the film is tensioned, thereby completing the storage of the film.
