Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope protected by the present utility model.

[0024] Please refer to Figure 1 - Figure 2 , an embodiment provided by the present utility model: An automatic paper cutting device for a thermal printer, including a workbench 1, the workbench 1 is used for fixedly carrying and installing the paper cutting device, a mounting block 2 is fixedly connected to the top of the workbench 1, a chute is opened on the left side of the mounting block 2, a shredder 3 is fixedly connected to the right side of the mounting block 2, the shredder 3 is a prior art and is used for crushing paper, which will not be elaborated here, a horizontal plate 4 is fixedly connected to the left side of the mounting block 2, the horizontal plate 4 is used for installing and carrying the cylinder 5, the cylinder 5 is installed on the top of the horizontal plate 4, an alignment mechanism 6 is arranged at the bottom of the horizontal plate 4, and a combing mechanism 7 is arranged on the left side of the mounting block 2;

[0025] Please refer to Figure 1 - Figure 3, the alignment mechanism 6 includes a transmission plate 601, a first roller 602, a first linkage rod 603, a second linkage rod 604, and a second roller 605. The transmission plate 601 is installed at the output end of the cylinder 5. The cylinder 5 is located at the top of the cross plate 4 and outputs pressure downward, causing the transmission plate 601 to press down. The first roller 602 is slidably connected to the inner wall of the transmission plate 601. The first linkage rod 603 is rotatably connected to the surface of the first roller 602. When the transmission plate 601 presses down, the first linkage rod 603 contacts the paper, causing the first roller 602 to slide. The second roller 605 is slidably connected to the inner wall of the transmission plate 601. The second linkage rod 604 is rotatably connected to the surface of the second roller 605. The first linkage rod 603 and the first roller 602 simultaneously drive the second linkage rod 604 and the second roller 605 to move. One end of the first linkage rod 603 away from the first roller 602 is hinged to one end of the second linkage rod 604 away from the second roller 605. The surface of the second roller 605 after moving contacts the telescopic rod 606.

[0026] Please refer to Figure 1 - Figure 3 , the alignment mechanism 6 further includes a telescopic rod 606, a vertical plate 607, and a retractable plate 608. The telescopic rod 606 is slidably connected to the inner wall of the transmission plate 601. During the sliding of the second roller 605, it contacts the telescopic rod 606. The vertical plate 607 is fixedly connected to one end of the telescopic rod 606 away from the second roller 605. The telescopic rod 606 drives the vertical plate 607 and the retractable plate 608 to expand and align with the bottom paper. Then, by slightly raising the cylinder 5, the vertical plate 607 and the retractable plate 608 are slightly reset to contact the edge of the paper. The retractable plate 608 is slidably connected to the inner wall of the vertical plate 607, facilitating the subsequent cutting work, eliminating the need for manual frequent adjustment of the paper position, saving operation time, and accelerating the entire printing and cutting process.

[0027] Please refer to Figure 4, the combing mechanism 7 includes a connecting rod 701, a transmission rod 702, and a connecting frame 703. The transmission rod 702 is fixedly connected to the surface of the air cylinder 5, the connecting rod 701 is fixedly connected to the surface of the transmission rod 702. When the air cylinder 5 resets, it drives the transmission rod 702 to move upward. The connecting frame 703 is fixedly connected to the bottom of the connecting rod 701. One end of the transmission rod 702 away from the air cylinder 5 is slidably connected to the left side of the mounting block 2. The upward movement of the transmission rod 702 drives the connecting frame 703 to move upward. The combing mechanism 7 further includes a pressing rod 704, a side sliding frame 705, and a pushing plate 706. The pressing rod 704 is hinged to the inner wall of the connecting frame 703. The connecting frame 703 enables the pressing rod 704 hinged to the inner wall of the connecting frame 703 to slide relatively within the inner wall of the side sliding frame 705. The side sliding frame 705 is fixedly connected to the top of the workbench 1. The pushing plate 706 is slidably connected to the inner wall of the side sliding frame 705. One end of the pressing rod 704 away from the connecting frame 703 is slidably connected to the inner wall of the side sliding frame 705. The pressing rod 704 drives the pushing plate 706 to move relatively, pushing the cut paper waste to the inlet of the paper shredder 3. The bottom of the pushing plate 706 is in contact with the top of the workbench 1, facilitating the operator to push the waste paper into the paper shredder 3 for shredding. The shredded paper scraps occupy less space, being convenient for storage and disposal.

[0028] Working principle: During use, when the staff cuts papers of different sizes, the paper is placed on the top of the workbench 1. Through the air cylinder 5, the air cylinder 5 outputs downward pressure at the top of the cross plate 4, causing the transmission plate 601 to press down. When the transmission plate 601 presses down, the first linkage rod 603 at its bottom contacts the paper to be cut, causing the first linkage rod 603 to drive the second linkage rod 604 to slide through the first roller 602 and the second roller 605 in the chute opened at the bottom of the transmission plate 601. During the sliding process of the second roller 605, it contacts the telescopic rod 606, causing the telescopic rod 606 to drive the vertical plate 607 and the retractable plate 608 to unfold and align with the bottom paper. Then, by slightly lifting the air cylinder 5, the vertical plate 607 and the retractable plate 608 are slightly reset to contact the paper edge, aligning the paper, achieving adaptive adjustment of paper alignment according to different paper areas, thus facilitating the subsequent cutting work, eliminating the need for manual frequent adjustment of paper position, saving operation time, accelerating the entire printing and cutting process. At the same time, when the paper cutting is completed, the air cylinder 5 resets, driving the transmission rod 702 to move upward. The upward movement of the transmission rod 702 drives the connecting frame 703 to move upward, causing the pressing rod 704 hinged to the inner wall of the connecting frame 703 to slide relatively within the inner wall of the side sliding frame 705. The pressing rod 704 drives the pushing plate 706 to move relatively, pushing the cut paper waste to the inlet of the paper shredder 3, facilitating the operator to push the waste paper into the paper shredder 3 for shredding. The shredded paper scraps occupy less space, being convenient for storage and disposal, reducing garbage accumulation.
