Description

Technical Field

[0001] This utility model relates to the field of printing press components, specifically a high-efficiency paper feeding and correction mechanism for printing presses. Background Technology

[0002] A printing press is a device that uses specific processes to copy text, images, and other content onto paper, plastic, metal, or other substrates. Therefore, it is used in fields such as publishing and packaging printing.

[0003] In the prior art, such as Chinese patent application number CN201920104846.8, a paper feeding structure for a printing press is provided. This paper feeding structure can adjust the paper feeding speed through a set of housings, and the set of control mechanisms can control the transmission mechanism, which facilitates paper feeding, improves paper feeding efficiency, and the set of paper suction trays can ensure the quality of paper feeding.

[0004] In existing printing presses, paper misalignment and edge skew during paper feeding can easily lead to misalignment of printed patterns, affecting print quality. Traditional paper feeding correction mechanisms rely on fixed guide rails or manual adjustment of side baffles, which are inefficient and difficult to achieve dynamic correction, especially at high-speed printing where the misalignment is more severe. Therefore, a high-efficiency paper feeding correction mechanism for printing presses is proposed to address these issues. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0019] This embodiment discloses a high-efficiency paper feeding and straightening mechanism for a printing press. (Refer to...) Figures 1-5The system includes a frame 1 and a receiving frame 6. A monitor 7 is fixedly connected to the bottom of the receiving frame 6. A pair of automatic push rods 8 are installed in the middle of the bottom of the receiving frame 6. A reinforcing frame 9 is installed at the transmission end of the automatic push rods 8. A photoelectric sensor 5 is installed at the front end of the reinforcing frame 9. An actuator motor 13 is fixedly connected to one side of the inner end of the reinforcing frame 9. A bidirectional screw 14 is installed at the transmission end of the actuator motor 13. Symmetrically distributed moving blocks 15 are threaded to the outer end of the bidirectional screw 14. A straightening frame 16 is fixedly connected to the front end of the moving blocks 15. A guide roller 17 is installed at the outer end of the straightening frame 16. By installing the photoelectric sensor 5 and the straightening frame 16, when the equipment... During paper feeding, photoelectric sensor 5, in conjunction with monitor 7, monitors the paper edge position and paper feeding status in real time. When a deviation occurs, the signal is fed back to the control system, and the actuator motor 13 starts to drive the bidirectional screw 14 and a pair of moving blocks 15 to perform threaded action. The moving blocks 15 move in opposite directions, driving the connected straightening frame 16 and guide roller 17, thereby achieving dynamic straightening. The guide roller 17 is covered with rubber material, which allows the mechanism to easily straighten the conveyed material while the flexible guiding structure avoids damage to the material during straightening, thus improving the practicality of the paper feeding straightening mechanism in printing presses.

[0020] Reference Figures 1-3 The bottom of the straightening frame 16 is fixedly connected with anti-slip rubber pads 18, and the bottom of the anti-slip rubber pads 18 is fixedly connected with protrusions 19 that are evenly distributed. By installing anti-slip rubber pads 18 and protrusions 19, the guiding effect of the straightening frame 16 can be increased. It can guide flexibly while preventing paper material from falling off, making the straightening work smoother. Reference Figure 2 and Figure 3 The bottom end of the guide roller 17 is fixedly connected to the arc-shaped guide component 20, which is located at the outer end of the straightening frame 16. By installing the arc-shaped guide component 20, the guide area of ​​the guide roller 17 can be increased, thus avoiding the situation where the guide roller 17 does not provide complete guidance and further improving the guiding effect of the device. Reference Figure 2 The upper end of the correction frame 16 is fixedly connected with a guide rod 21. By installing the guide rod 21, the structural stability of the correction frame 16 can be increased. Reference Figure 1 A drive unit 2 is installed at the outer end of the frame 1, and a conveyor belt 3 is installed at the transmission end of the drive unit 2. A controller 4 is installed at the left end of the frame 1. By installing the frame 1, the frame 1 can form a support connection structure at the outer end of the drive unit 2 and the conveyor belt 3, thereby improving the stability of the connection of the device structure. Reference Figure 1 and Figure 5A support frame 6 is installed at the upper end of the frame 1. By installing the support frame 6, the support frame 6 can form a connection structure outside the automatic push rod 8 and other drive correction components, which further improves the stability of the connection between the components of the mechanism. Reference Figure 2 and Figure 3 Guide blocks 10 are installed at both ends of the reinforcing frame 9. The inner end of the guide block 10 is slidably connected to the slide rod 11. By installing the guide block 10 and the slide rod 11, when a pair of automatic push rods 8 are activated, they can drive the reinforcing frame 9 and the connected correction components to adjust their positions. With the help of the moving block 15, the mechanism can be conveniently adjusted and corrected according to the distance or thickness of the paper. When the height of the reinforcing frame 9 is adjusted, the guide block 10 moves with it and slides outside the slide rod 11. The slide rod 11 guides it, which makes the structure easy to adjust and more stable to move, further improving the correction effect of the mechanism. Reference Figure 2 and Figure 3 The top end of the slide rod 11 is fixedly connected to the bottom end of the support frame 6. The bottom end of the slide rod 11 is equipped with a limit head 12. The inside of the reinforcing frame 9 is provided with a guide groove 22. The guide groove 22 is slidably connected to the connecting block at the top of the moving block 15. By setting the guide groove 22, the guide groove 22 can guide the adjusted moving block 15 and prevent the moving block 15 from flipping when it moves.

[0021] Working principle: The paper is conveyed by the conveyor belt 3. During the conveying process, the photoelectric sensor 5, together with the monitor 7, monitors the edge position of the paper and the paper feeding status in real time. When a deviation occurs, the signal is fed back to the control system, and the actuator motor 13 is started to drive the bidirectional screw 14 and a pair of moving blocks 15 to perform threaded action. The moving blocks 15 move in opposite directions, driving the connected straightening frame 16 and guide roller 17, thereby realizing dynamic correction. In addition, during adjustment, a pair of automatic push rods 8 can be activated according to the paper thickness. After the pair of automatic push rods 8 are activated, they can drive the reinforcement frame 9 and the connected straightening components to adjust their positions. With the help of the moving blocks 15, the mechanism can be easily adjusted and corrected according to the distance or thickness of the paper. When the height of the reinforcement frame 9 is adjusted, the guide block 10 moves with it and slides outside the slide rod 11. The slide rod 11 guides it, which makes the structure easy to adjust and more stable in movement. Multiple adjustment components are activated to adjust the position of the straightening frame 16 and the guide roller 17, thereby achieving dynamic straightening. The guide roller 17 is covered with rubber material, which allows the mechanism to easily straighten the conveyed material while the flexible guiding structure avoids damage to the material during the straightening process. Anti-slip rubber pads 18 and protrusions 19 are set at the bottom of the straightening frame 16 to increase the guiding effect of the straightening frame 16 adjustment. While providing flexible guidance, it also prevents the paper material from falling off, making the straightening work smoother.
