[0013] Preferably, in order to facilitate the centralized processing of cut waste paper, a storage box is placed below the outlet of the deflector.

[0014] (III) Beneficial effects

[0015] The printing paper cutting mechanism can automatically drop the scattered waste paper into the guide cover through the design of the leakage plate, and the waste paper flows out from the outlet of the guide cover, thereby eliminating the step of manual cleaning and improving the processing efficiency.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-Figure 4 The utility model provides a technical solution: a printing paper cutting mechanism, including a paper shearing machine chassis 1, a knife disc frame 2 fixedly mounted on the paper shearing machine chassis 1, a knife frame 3 longitudinally moving on the knife disc frame 2, a driving mechanism A4 fixedly mounted on the paper shearing machine chassis 1 for driving the knife frame 3 to move, a rear support plate 5 fixedly mounted on the paper shearing machine chassis 1 for supporting a stack of printing paper, an ejection baffle 6 laterally moving on the rear support plate 5 for ejecting the paper stack, a driving mechanism B7 fixedly mounted on the rear support plate 5 for driving the ejection baffle 6 to move, and a front support plate 8 arranged at a position on the paper shearing machine chassis 1 corresponding to a feed port.

[0025] One end of the front support plate 8 close to the rear support plate 5 is hinged with a downwardly opened leakage plate 81, and the bottom of the front support plate 8 is fixedly connected to a deflector 82 fixedly connected to the rear support plate 5. The leakage plate 81 is connected to the tool holder 3 through a sling 32, wherein a connecting column 811 is provided on the side of the leakage plate 81, and a fixed column 31 is provided at an upper position corresponding to the connecting column 811 on the tool holder 3, and both ends of the sling 32 are respectively wrapped around the connecting column 811 and the fixed column 31.

[0026] When in use, the printed paper stack is placed on the front support plate 8, then pushed under the knife holder 3 and the ejection baffle 6 is pushed close to the paper stack by the driving mechanism B7, and finally the position to be cut is adjusted by pushing the paper stack by the ejection baffle 6. When cutting, the knife holder 3 is driven to fall by the driving mechanism A4, so as to perform cutting. As the knife holder 3 falls, since the leakage plate 81 is connected by the sling 32, the leakage plate 81 gradually opens downward under the action of its own weight. When the knife holder 3 falls completely and cuts the paper stack, the scattered waste paper will fall into the air guide cover 82 because the leakage plate 81 is opened, and flow out from the outlet of the air guide cover 82, eliminating the manual cleaning step and improving the processing efficiency. After that, when the driving mechanism A4 resets the knife holder 3 again, the leakage plate 81 will be closed again by the sling 32, keeping the front support plate 8 and the leakage plate 81 flat, making it convenient to organize the paper stack for subsequent cutting.

[0027] Furthermore, a bracket 83 fixedly connected to the bottom of the air deflector 82 is provided; the air deflector 82 is further fixed to the paper shearing machine chassis 1 through the bracket 83, thereby providing sufficient supporting force to ensure stability.

[0028] It should be noted that a groove 821 is provided on the side of the air deflector 82 to accommodate the movement of the connecting column 811; since the leakage plate 81 is connected to one end of the sling 32 through the connecting column 811, the leakage plate 81 will also move with the connecting column 811 when it is opened. The existence of the groove 821 allows the connecting column 811 to move freely, thereby ensuring the normal opening of the leakage plate 81.

[0029] Furthermore, a storage box 9 is placed below the outlet of the deflector 82; the waste paper flowing out through the deflector 82 is collected by the storage box 9, which is convenient for subsequent centralized processing, further saving time and improving efficiency.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
