Description

Technical Field

[0001] The utility model belongs to the technical field of printing machines, and in particular relates to a typesetting printing machine. Background Art

[0002] A typesetting printing press is a device used to print typeset graphic content onto paper or other materials. With the development of technology, typesetting printing presses have undergone a transformation from traditional mechanical printing presses to digital printing presses. A printing press is a device that presses the inked surface onto paper. A printing press is generally composed of mechanisms such as plate loading, inking, embossing, and paper feeding. In order to increase the printing processing rate, the multiple printing processes are designed to be completed in the form of an assembly line, and each process requires a certain amount of operation time. For continuously working printing presses, some processes need to be paused to complete subsequent processes to avoid paper stacking when the paper feeding mechanism continuously feeds paper.

[0003] The spacing between the vertical baffles on both sides of the conveyor belt of the current printing press cannot be adjusted, so it can only process one size of paper, which has low applicability. At the same time, due to the thickness of the printed paper stack, it is not convenient to transport the paper stably. The paper is easily offset under the influence of wind and other factors. In the paper conveying process, due to the height difference of the paper, there is a gap between the bottom of the paper and the feed board. When feeding the paper, the air at the bottom of the paper may cause the paper to wrinkle, resulting in equipment failure.

[0004] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to those skilled in the art.

Sliding springs 15 are provided between the sliding grooves 13 and the sliding blocks 14, and feeding rollers 16 are provided between the sliding blocks 14. A feeding motor 17 is provided on one side of the feeding roller 16. A feeding rod 25 is slidingly provided at the bottom of the loading rack 2, and a loading plate 26 is fixedly provided at one end of the loading rod 25. A supporting slide 27 is fixed on the loading plate 26. A supporting slide 28 cooperating with the supporting slide 27 is provided on the loading rack 2, and a limit block 29 is provided at one end of the loading rod 25. A limit groove 30 cooperating with the limit block 29 is provided at the bottom of the loading rack 2.

[0029] In this embodiment, when feeding paper, a stack of paper is moved to the position of the loading plate 26 according to its size, and the loading rod 25 slides at the bottom of the loading rack 2, and the limit block 29 slides in the limit groove 30 to limit the moving direction and position of the loading plate 26. The supporting slide 27 moves in the supporting slide groove 28 to support the paper. The loading plate 26 makes the printed paper neatly arranged on the loading rack 2 and extends under the feeding roller 16, squeezing the sliding block 14 and the sliding spring 15 upward to raise the height of the feeding roller 16 and the feeding motor 17. The printing paper is pressed by the pressing rod 6 and the pressing plate 7 on the pressing frame 5 to prevent it from moving. When feeding paper, the drive motor is started. 12. The driving motor 12 drives the cam 10 to rotate. When the long axis end of the cam 10 contacts the clamping ring 11, the clamping ring 11 drives the clamping rod 6 end of the clamping frame 5 to rotate upward, and then starts the feeding motor 17. The feeding motor 17 drives the feeding roller 16 to rotate, driving the top sheet of printing paper to move. At the same time, as the cam 10 continues to rotate, the clamping frame 5 drives one end of the clamping rod 6 to rotate downward under the action of the torsion spring, and cooperates with the clamping plate 7 and the clamping spring 9 to continue to clamp the remaining printing paper to prevent deviation. With the elastic force of the sliding spring 15, the sliding block 14 moves downward along the sliding groove 13, so that the feeding roller 16 continues to stably contact the top sheet of printing paper to feed paper.

[0030] In this embodiment, the adjustment frame 4 is equipped with an adjustment motor 18, with an adjustment roller 19 at the output end of the adjustment motor 18. A feed roller 20 is also rotatably mounted on the adjustment frame 4. Multiple rubber rings 21 are axially mounted between the feed roller 16 and the adjustment roller 19. A hinged adjustment plate 22 is hingedly mounted on the adjustment frame 4. The adjustment plate 22 is curved, with an adjustment spring 23 interposed between the adjustment plate 22 and the adjustment frame 4. The adjustment plate 22 is also provided with vent holes 24. As the printing paper moves, it moves onto the curved adjustment plate 22. Air between the printing paper and the adjustment plate 22 is evacuated through the vent holes 24, preventing warping at one end of the printing paper. Supported by the adjustment spring 23, the printing paper extends between the adjustment plate 22 and the adjustment roller 19, activating the adjustment motor 18. This drives the adjustment roller 19 to rotate, which in turn drives the printing paper onto the feed roller 20, resulting in smooth and stable movement at a fixed height, followed by printing.

[0031] In summary, when using, when feeding paper, a stack of paper is moved to the position of the loading plate 26 according to its size, and the loading rod 25 slides at the bottom of the loading rack 2, and the limit block 29 slides in the limit groove 30 to limit the moving direction and position of the loading plate 26, and the supporting slide 27 moves in the supporting slide groove 28 to support the paper, and the printing paper is neatly arranged on the loading rack 2 through the loading plate 26, and extends under the feeding roller 16, squeezing the sliding block 14 and the sliding spring 15 upward to raise the height of the feeding roller 16 and the feeding motor 17, and the printing paper is pressed by the pressing rod 6 and the pressing plate 7 on the pressing frame 5 to prevent it from moving, and when feeding paper, the drive motor is started. 12. The driving motor 12 drives the cam 10 to rotate. When the long axis end of the cam 10 contacts the clamping ring 11, the clamping ring 11 drives the clamping rod 6 end of the clamping frame 5 to rotate upward, and then starts the feeding motor 17. The feeding motor 17 drives the feeding roller 16 to rotate, driving the top sheet of printing paper to move. At the same time, as the cam 10 continues to rotate, the clamping frame 5 drives one end of the clamping rod 6 to rotate downward under the action of the torsion spring, and cooperates with the clamping plate 7 and the clamping spring 9 to continue to clamp the remaining printing paper to prevent deviation. With the elastic force of the sliding spring 15, the sliding block 14 moves downward along the sliding groove 13, so that the feeding roller 16 continues to stably contact the top sheet of printing paper to feed paper.

[0032] As the printing paper moves, it moves onto the arc-shaped adjustment plate 22. The air between the printing paper and the adjustment plate 22 is evacuated through the exhaust holes 24 to prevent one end of the printing paper from warping. Supported by the adjustment spring 23, the printing paper extends between the adjustment plate 22 and the adjustment roller 19. The adjustment motor 18 is started, and the adjustment motor 18 drives the adjustment roller 19 to rotate, thereby driving the printing paper to move onto the conveying roller 20, and then move smoothly and stably at a fixed height, and then printing is carried out.
