[0015] This utility model embodiment provides a novel printer cutter pressure structure and printer, wherein, as shown in the following example... Figures 2-7 As shown, the new printer cutter pressure structure includes: The first cutting blade 11 is fixedly mounted on the housing of the printer body 10; The second cutter 12 has a V-shaped cutting edge, and its cutting edge is set opposite to the cutting edge of the first cutter 11. The cutter support 13 is connected to the second cutter 12. The cutter support 13 is connected to a drive device (drive motor, etc.) and the second cutter 12 is driven by the drive device to reciprocate relative to the first cutter 11 so that the blades of the two cutters mesh with each other to cut. Spring 14, usually made of metal, is connected to the blade holder 15 on both sides, and its middle part abuts against the back of the second cutter 12. A pressure protrusion 16 is provided on the printer housing. The pressure protrusion 16 corresponds to the cutting position of the middle section of the second cutter 12 to increase the meshing pressure of the middle section of the second cutter 12 on the first cutter 11. In this embodiment, the structure and working principle of the first cutter 11, the second cutter 12, the cutter bracket 13, the spring 14, and the blade holder 15 are all prior art and will not be described in detail here.

[0016] During operation, the first cutter 11 is fixed in position, and the second cutter 12 is moved from its retracted state (e.g., under the action of the cutter holder 13) Figure 6 As shown, the second cutter 12 moves towards the side of the first cutter 11. When the middle part of the second cutter 12 moves to the cutting position with the first cutter 11 (as shown), Figure 7 As shown in the figure, the pressure protrusion 16 located on one side of this position applies vertical pressure to the middle of the spring piece 14, causing the spring piece 14 to press against the middle of the second cutter 12, thereby increasing the meshing pressure of the middle section of the second cutter 12 on the first cutter 11. The printer using the novel printer cutter pressure structure provided in this embodiment has a good paper cutting effect and solves the problem of incomplete cutting of the middle of the paper in the existing cutter structure.

[0017] The novel printer cutter pressure structure provided in this embodiment of the invention effectively solves the problem of incomplete cutting of the middle of the paper in existing cutter structures by combining the pressure protrusion with the first cutter, the second cutter, the cutter bracket, the spring, and the blade holder, thus achieving a good paper cutting effect.

[0018] In a specific implementation, it also includes a cutter box, which contains the second cutter 12, a cutter support 13, a spring piece 14, and a drive structure for the second cutter 12. A pressure protrusion 16 is located on the side wall of the cutter box cover 17 at the center of the spring piece 14 (e.g., Figure 4 , Figure 5 (As shown); the pressure protrusion 16 is supported by, but is not limited to, integrally formed with the cutter box cover 17, or connected to the cutter box cover 17 by an adhesive structure. In this embodiment, by integrating the pressure protrusion 16 into the side wall of the cutter box cover, it can be ensured that the protrusion automatically aligns with the center of the spring piece when the box cover is closed, avoiding assembly errors.

[0019] In practice, the thickness of the pressure protrusion 16 is 1.5mm-2mm, and the thickness range ensures that the protrusion generates sufficient deformation pressure.

[0020] In practice, the length of the pressure protrusion 16 perpendicular to the blade direction is 5mm-6mm. The length range design ensures that the pressure evenly covers the weak cutting area and avoids excessive interference with the reciprocating motion trajectory of the cutter support, thus maintaining the smoothness of the cutting action.

[0021] In specific implementation, the spring piece 14 is provided with an extended support protrusion 142 in the middle (e.g., Figure 8 As shown), the position of the support protrusion 142 corresponds to that of the pressure protrusion 16. In this embodiment, the laterally extending support protrusion 142 allows the pressure applied by the pressure protrusion 16 to be transmitted more directly to the cutting part of the second cutter 12 (e.g., ...). Figure 7 As shown in the figure, the pressure transmission path has been optimized, and the meshing pressure of the middle part of the second cutter 12 on the first cutter 11 has been enhanced, resulting in better and smoother paper cutting.

[0022] Furthermore, the spring piece 14 is arc-shaped with several asymmetrical notches 141. To accommodate other functional designs, the spring piece 14 in this embodiment has several asymmetrical notches 141. These asymmetrical notches result in an irregular, non-formed shape, leading to uneven stress distribution and insufficient spring force. This can cause the central portion of the cutter to fail to completely cut the paper during full paper cutting. In this embodiment, the asymmetrical spring piece 14 is combined with the aforementioned pressure protrusion 16, significantly solving the problem of incomplete cutting during full paper cutting caused by the shape of the spring piece 14. The printer using this embodiment offers good paper cutting performance, is practical, and has a simple structure, making it widely applicable in the printing industry.

[0023] This utility model also provides a novel printer that adopts the novel printer cutter pressure structure described above.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
