[0069] With this design, the second cylinder 808 drives the paper guide block 804 and the second support block 805 away from the fourth support block 809, making it easier for the packaging paper tape 10 to pass through the paper hole 803.

[0070] In addition to this embodiment, the number of the second paper guides 810 may also be one, two, three or more than four.

[0071] A first air chamber groove 8091 is provided on the side of the fourth support block 809 close to the positioning plate 801, and the first air chamber groove 8091 and the top surface of the positioning plate 801 together form a first air chamber, and the first air chamber is connected to the air source. A plurality of fourth air blowing holes 8011 are provided on the positioning plate 801 close to the paper feeding hole 803, and the fourth air blowing holes 8011 are connected to the first air chamber.

[0072] A second air chamber groove 8051 is provided on the side of the second support block 805 close to the paper guide block 804. The second air chamber groove 8051 and the top surface of the paper guide block 804 together form a second air chamber. The second air chamber is connected to the air source. A plurality of fifth air blowing holes 8041 are provided on the paper guide block 804. The fifth air blowing holes 8041 are connected to the second air chamber.

[0073] With this design, the airflow blown out from the fourth air hole 8011 and the fifth air hole 8041 forms airflow walls on both sides of the packaging paper tape 10, and a third channel is formed between the two airflow walls, which effectively guides the packaging paper tape 10 and ensures that the packaging paper tape 10 moves smoothly downward.

[0074] The adjusting component 9 includes a third connecting block 901, which is fixedly connected to the support frame 701, and a second guide rod 902 is slidably connected inside the third connecting block 901. A threaded rod 903 is threadedly connected inside the third connecting block 901, and the threaded rod 903 and the second guide rod 902 are arranged in parallel. A fourth connecting block 904 is arranged above the third connecting block 901, and the fourth connecting block 904 is fixedly connected to its corresponding third support plate 802, the second guide rod 902 is fixedly connected to the fourth connecting block 904, the threaded rod 903 is rotatably connected to the fourth connecting block 904, and the top of the threaded rod 903 passes through the fourth connecting block 904 and is fixedly connected to a second hand wheel 905.

[0075] With this design, turning the second hand wheel 905 facilitates adjusting the upper paper support assembly 8 to be closer to or farther from the lower paper support assembly 7, thereby facilitating different specifications of paper strips to pass through the cavity between the support plate 703 and the positioning plate 801 and enter the next process.

[0076] Thumb screws 906 are installed at both ends of the support frame 701. After the position of the upper paper support assembly 8 is adjusted by the adjustment assembly 9, tightening the thumb screws 906 facilitates the third support plate 802 and the support frame 701 to be fixed together, thereby fastening the upper paper support assembly 8 and the lower paper support assembly 7 together.

[0077] When in use, the packaging paper belt 10 coming from the paper placing mechanism is Figure 3 As shown, it is wound on the first paper guide roller 205, the first driven roller 5022, the active roller 5012, the second paper guide roller 5052 and the second driven roller 5032. The active roller 5012 rotates to drive the packaging paper belt 10 to move downward. The rational design of the first driven roller assembly 502 facilitates the packaging paper belt 10 to pass between the first driven roller 5022 and the active roller 5012. The rational design of the second driven roller assembly 503 facilitates the packaging paper belt 10 to pass between the second driven roller 5032 and the active roller 5012. The rational design of the paper stop assembly 504 facilitates the packaging paper belt 10 to pass between the paper stop board 5041 and the multiple paper stop blocks 5043, which plays a good guiding role for the packaging paper belt 10.

[0078] The wrapping paper belt 10 continues to go down through the first channel and the second channel. When the wrapping paper belt 10 passes through the paper hole 803 , the paper guide block 804 and the second support block 805 move away from the fourth support block 809 , making it easier for the wrapping paper belt 10 to pass through the paper hole 803 .

[0079] The wrapping paper tape 10 continues to go down through the third channel. When the wrapping paper tape 10 passes through the flap hole, the flap 704 moves away from the flap hole, thereby increasing the space for the wrapping paper tape 10 to pass through the flap hole and facilitating the wrapping paper tape 10 to pass through the flap hole.

[0080] When the packaging paper belt 10 reaches the specified position, the flap 704 swings to block the flap hole and forms a lifting surface together with the support plate 703, which is convenient for effectively supporting the long paper strips pushed from the conveyor belt mechanism. At this time, the paper guide block 804 and the second support block 805 also move and approach the fourth support block 809, leaving only a gap for the packaging paper belt 10 to pass through.

[0081] Then, the cutting knife shaft 604 rotates and drives the cutting knife 606 to move. The cutting knife 606 cooperates with the fixed knife 602 to cut the packaging paper tape 10. The pushing mechanism pushes the packaging paper tape 10 and the long paper strip to the next process for paper pressing and hot sealing. In the process of the packaging paper tape 10 and the long paper strip passing through the cavity between the support plate 703 and the positioning plate 801, the packaging paper tape 10 forms an effective wrapping for the forward surface, top surface and bottom surface of the long paper strip through the limiting of the support plate 703 and the positioning plate 801.

[0082] Embodiment 2: Four blowing plates 611 are fixedly connected to the bottom surface of the fixed knife holder 601. The blowing plates 611 replace the first paper guide 608 and form a second channel together with the airflow blown out of the third blowing hole, thereby ensuring that the packaging paper strip 10 moves downward smoothly.

[0083] In addition to this embodiment, the number of the blowing plates 611 can also be one, two, three or more than four.

[0084] like Fig.18 As shown, two blowing components are arranged on the blowing plate 611 .

[0085] In addition to this embodiment, the number of the blowing components can also be one or more than two.

[0086] The blowing assembly includes an air cavity 6111 opened in the blowing plate 611, the air cavity 6111 is connected to the air source, and an air outlet surface 6112 and an air guide surface 6114 are provided on the side of the blowing plate 611 close to the third blowing pipe 610, and a plurality of sixth blowing holes 6113 are opened on the air outlet surface 6112, and the sixth blowing holes 6113 are connected to the air cavity 6111.

[0087] With this design, the airflow blown out of the sixth air hole 6113 and the airflow blown out of the third air hole together form a second channel, and the packaging paper belt 10 is guided through the second channel, ensuring that the packaging paper belt 10 moves downward smoothly.

[0088] A plurality of air leakage holes 6115 are provided on the air guide surface 6114 .

[0089] With this design, when the airflow blown out of the sixth blowing hole 6113 is too large, it can be discharged from the vent hole 6115, so that the airflow on both sides of the packaging paper belt 10 is more balanced and stable, further ensuring that the packaging paper belt 10 moves downward smoothly.

[0090] For those skilled in the art, according to the teachings of the present invention, without departing from the principles and spirit of the present invention, changes, modifications, substitutions and variations made to the implementation methods are still within the protection scope of the present invention.
