They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0015] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0016] This utility model provides a printer paper cutting nozzle anti-clogging structure and a printer, wherein the printer paper cutting nozzle anti-clogging structure includes a guide block 13; the guide block 13 is disposed at the paper cutting inlet 15 and on one side of the moving blade movable hole 14; the guide block 13 is in contact with the paper surface of the printing paper.

[0017] In specific implementation, such as Figures 1-3 As shown, a movable blade abutment 14 is provided below the fixed blade 11; the movable blade 12 is disposed within the movable blade abutment 14; a paper feed inlet 15 is located on one side of the movable blade abutment 14; a guide block 13 is provided on the side of the movable blade abutment 14 located at the paper feed inlet 15; the guide block 13 is in contact with the paper surface of the printing paper; as shown... Figure 2As shown, the guide block 13 increases the height difference between the front end (cutting end) of the printing paper and the moving blade movable hole 14, thereby raising the paper feed end and making it less likely for the front end of the printing paper to droop into the moving blade movable hole 14. In this embodiment, the fixed blade 11, moving blade 12, moving blade movable hole 14, and paper cutting inlet 15 are all existing technologies and will not be described in detail here.

[0018] The anti-clogging structure for the printer paper cutting nozzle provided in this embodiment solves the problem of printing blockage caused by the paper cutting nozzle falling into the moving blade hole by providing a guide block on the side of the moving blade hole located at the paper cutting inlet. This is achieved by raising the paper feed end, making it less likely for the front end of the printing paper to droop into the moving blade hole.

[0019] Furthermore, the guide block 13 is arranged along the length direction of the moving knife movable hole 14 and partially blocks the moving knife movable hole 14.

[0020] In specific implementation, such as Figure 2 , Figure 3 As shown, the guide block 13 is arranged along the length of the moving tool movable hole 14 and partially blocks the moving tool movable hole 14, thereby reducing the size of the moving tool movable hole 14 while ensuring the normal movement of the moving tool 12 (e.g., Figure 2 The width of the paper feed hole 14 in the paper feeding direction (as shown) further reduces the probability of the front end of the printing paper falling into the moving blade hole 14. In this embodiment, the approach addresses both increasing the height of the front end (cutting end) of the printing paper and decreasing the width of the moving blade hole 14 in the paper feeding direction. The combination of these two approaches significantly alleviates the paper clogging problem in this area, resulting in better performance.

[0021] Furthermore, a ramp 131 is provided on one side of the guide block 13.

[0022] In specific implementation, such as Figure 2 As shown, a ramp 131 is provided on one side of the guide block 13. Through the ramp structure, when the printing paper is cut and waiting for the next cut, the paper output direction of the front end of the printing paper can be changed by the combination of the ramp 131 and the paper feed port 15, so that it is closer to the fixed blade 11. Combined with the above-mentioned anti-clogging structure of the printer paper cutting port, it effectively solves the problem of printing paper clogging at the cutting blade.

[0023] Furthermore, the guide block 13 extends along the side wall of the moving tool chamber 16 and is connected to the moving tool chamber 16 via the side plate 132.

[0024] In specific implementation, such as Figure 3As shown, the guide block 13 extends downward along the side wall of the moving tool chamber 16 and is connected to the side wall of the moving tool chamber 16 via the side plate 132. The connection structure includes, but is not limited to, bolt connection, snap-fit ​​connection, etc. In this embodiment, by extending the guide block 13 to the side wall of the moving tool chamber 16 and by the mounting structure of the side plate 132, the interference of the installation of the newly added guide block 13 structure on the operation of the cutting tool and other components can be reduced.

[0025] This utility model also provides a printer that uses the anti-clogging structure for the printer paper cutter as described above.
