Description

Technical Field

[0001] The present application relates to the field of printing equipment, and in particular to an automatic paper feeding device for a printing press. Background Art

[0002] A printing press is a device specifically designed for paper printing. Currently, commercially available printing units are often limited to single offset, gravure, or flexographic printing. Depending on the printing requirements, multiple offset, gravure, or flexographic printing passes may be required, and the order of printing may vary. Printing presses are categorized as sheet-fed or web-fed, depending on the format of the printed material. Existing cardboard printing equipment is relatively large, resulting in a high cardboard feed area. This requires manual loading of cardboard onto the feed area, a labor-intensive process. Furthermore, due to labor limitations, workers can only place a few cardboard sheets at a time, preventing large quantities from being placed at once.

[0003] An automatic paper feeding device for a printing press is now provided. Utility Model Content

[0053] Working or installation process:

[0054] The stacked cardboard is placed on the top wall of the placement plate 20 and the cardboard is located between the two clamping plates 28. Then, the two drive motors 26 are started at the same time, and one of the drive motors 26 is started in the forward direction and the other drive motor 26 is started in the reverse direction. The output shaft of the drive motor 26 drives the clamping screw 27 to rotate. The two clamping screws 27 rotate in the forward direction and the reverse direction respectively, and are threadedly connected to the clamping plates 28 through the clamping screws 27. The two clamping plates 28 move toward each other and move toward the side close to the cardboard until the clamping plates 28 on both sides contact the side of the cardboard. Then, the drive motor 26 stops starting, and the clamping plates 28 limit the cardboard to prevent it from sliding during the conveying process.

[0055] Afterwards, the lifting motor 13 is started, and the output shaft of the lifting motor 13 drives the lifting screw 15 to rotate. The lifting screw 15 is threadedly connected to one of the lifting blocks 16 and drives the lifting block 16 to move upward along the groove wall of the lifting groove 14. The lifting block 16 drives the rack 18 to move upward. The rack 18 pushes the first connecting block 19 and synchronously drives the first connecting block 19 to move upward. The first connecting block 19 drives the placement plate 20 to move upward. The placement plate 20 drives the cardboard stacked on the placement plate 20 to move upward; after the placement plate 20 drives the cardboard to move upward and moves until the bottom wall of the placement plate 20 is in smooth contact with the top wall of the frame 11, the lifting motor 13 stops working and controls the placement plate 20 to stay at this height;

[0056] Afterwards, the conveying motor 23 is started, and the output shaft of the conveying motor 23 drives the driving gear 24 to rotate. The driving gear 24 engages with the rack 18 and drives the first connecting block 19 to move along the extension direction of the rack 18. The first connecting block 19 drives the placement plate 20 to move along the extension direction of the rack 18 until the placement plate 20 is moved to the cardboard feed position of the printing press; there is no need to manually transport the cardboard to the cardboard feed position of the printing press.
