[0012] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0013] like Figures 1 to 3 As shown, a cutting knife air blowing assembly includes: a knife holder 2, a knife body 3, a nozzle 4, and an elbow connector 5. The knife holder 2 has a first side 21, a second side 22, and a bottom surface 23. An air passage 24 is provided on the knife holder 2. One end of the air passage 24 passes through the bottom surface 23 of the knife holder 2, and the other end of the air passage 24 passes through the first side 21 of the knife holder 2. The knife body 3 is installed on the second side 22 of the knife holder 2. The nozzle 4 is installed on the bottom surface 23 of the knife holder 2 and communicates with the air passage 24. The elbow connector 5 is installed on the first side 21 and communicates with the air passage 24.

[0014] The cleverly designed ventilation channel 24 on the cutter holder 2 has one end connected to the nozzle 4 through the bottom surface 23, and the other end connected to the elbow pipe 5 on the first side 21, forming an airflow ventilation channel 24. When an external air source inputs compressed air through the elbow pipe 5, the airflow quickly reaches the nozzle 4 along the ventilation channel 24 and is ejected from the nozzle 4 at high speed. After the cutting operation is completed, this strong airflow can quickly blow the waste paper generated by cutting away from the vicinity of the bottom surface 23 of the cutter holder 2, which helps to reduce the waste paper residue around the cutting components, reduces the waste paper stuck at the book outlet, greatly improves the stability and continuity of equipment operation, reduces downtime caused by cleaning paper jams, and improves work efficiency.

[0015] The application is installed near the book outlet of the device.

[0016] Specifically, the first side 21 of the tool holder 2 is provided with a number of countersunk holes 25, and a through hole 26 is provided at the bottom of the countersunk hole 25. The tool holder 2 is connected to the tool body 3 by a bolt 6 passing through the through hole 26. The bolt 6 is located inside the countersunk hole 25.

[0017] In this application, bolt 6 is an internal hex bolt or a hex bolt 6.

[0018] Specifically, the elbow connector 5 is an L-shaped threaded elbow, and the elbow connector 5 is threadedly connected to the tool holder 2.

[0019] Specifically, the tool holder 2 is provided with a limiting part 27, the limiting part 27 has a lower limiting surface 271, the lower limiting surface 271 is connected to the second side surface 22, and the upper end of the tool body 3 abuts against the lower limiting surface 271.

[0020] When the upper end of the blade body 3 abuts against the lower limit surface 271, the installation height of the blade body 3 in the vertical direction can be quickly determined, making the installation of the blade body 3 more accurate.

[0021] Specifically, the air outlet of nozzle 4 is directed toward the blade of blade body 3.

[0022] Specifically, the nozzle 4 has two nozzles located in the middle of the blade of the blade body 3.

[0023] Considering the issue of uniform force distribution, cutting is generally performed by placing the nozzle in the middle position. Therefore, the nozzle 4 should be aligned with the middle position of the blade body 3.

[0024] It should be noted that all directional indications in the embodiments of the present invention, such as up, down, left, right, front, back, etc., are only used to explain the relative positional relationship and movement of the components in a specific posture, as shown in the attached figure. If the specific posture changes, the directional indication will also change accordingly.

[0025] Furthermore, the use of terms such as "first" and "second" in this invention is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Meanwhile, the word "and / or" throughout the text means including three solutions; for example, "A and / or B" includes solution A, solution B, or a solution that simultaneously satisfies A and B. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them.
