Description

Technical Field

[0001] This utility model relates to the field of printing press technology, specifically to a feeding mechanism for a printing press. Background Technology

[0002] Printing refers to the technology of mass-producing copies of original manuscripts such as text, pictures, and photographs by transferring ink to the surface of materials such as paper, textiles, and leather through processes such as plate making, inking, and pressure application. In traditional paper printing, printing presses are frequently used to print on the paper surface. A printing press typically consists of four parts: a paper feeding device, a positioning and conveying device, a printing device, and a paper receiving device. The operation of a printing press requires a continuous input of the material to be printed, such as paper. The feeding mechanism ensures that these materials are delivered into the printing area of ​​the printing press in an orderly and stable manner, thereby improving processing efficiency.

[0003] Chinese Utility Model Patent Publication No. CN 213037336 U discloses a feeding mechanism for a printing press. This feeding mechanism, when multiple sheets of paper need to be stacked on a stacking platform, first places the paper on a moving platform. A power component drives the moving platform and the paper upwards, and a drive component pushes the paper onto the stacking platform. This can replace manual handling by workers, reducing labor costs and improving efficiency. However, this feeding mechanism lacks longitudinal and transverse alignment components, which can easily lead to material misalignment during the feeding process, resulting in poor printing quality and a high number of defective prints, thus reducing its practicality. Summary of the Invention

[0013] Through the above technical solution, the sliding design of the slide bar in the slide groove enables the horizontal alignment component to flexibly adjust the printing material in the horizontal direction, further improving the accuracy of material alignment and ensuring the precise position of the printed pattern in the horizontal direction.

[0014] Preferably, a grip is fixedly installed at the end of the slide rod away from the slide sleeve, and a positioning seat and an alignment rod are fixedly installed at the end of the slide rod away from the grip.

[0033] Specifically, the longitudinal alignment component 6 includes a slider 601, an alignment rod 602 fixedly mounted on the outer surface of the slider 601, and an extension block 603 and a positioning block 604 fixedly mounted on the other end of the alignment rod 602 away from the slider 601. The alignment rod 602 is adapted to the tray 15. The advantage is that the longitudinal alignment component 6 can effectively align the material to be printed in the longitudinal direction, ensuring that the longitudinal position of the material is accurate when it enters the printing press, avoiding printing quality problems caused by longitudinal position deviation. At the same time, the sliding design of the slider 601 makes adjustment convenient and flexible, and can be quickly adjusted according to the different sizes of the material to be printed.

[0034] Specifically, an insert rod 605 is inserted and installed on the outer surface of the extension block 603. The insert rod 605 is adapted to the positioning groove 8 and the positioning groove 16. The advantage is that the adaptation design of the insert rod 605 with the positioning groove 8 and the positioning groove 16 can fix the longitudinal alignment component 6 in the adjusted position, prevent the longitudinal alignment component 6 from moving during the printing process, ensure the stability and accuracy of the longitudinal alignment, and further improve the printing quality.

[0035] Specifically, the inner surface of the mounting sleeve 10 is provided with an adjustment groove 12, and an adjustment bolt 13 is provided through the inner surface of the adjustment groove 12. The slot 11 and the horizontal alignment component 14 are installed by plugging in. The adjustment bolt 13 passes through the adjustment groove 12 and extends to the inner surface of the horizontal alignment component 14. The advantage is that, through the design of the adjustment groove 12 and the adjustment bolt 13, the position of the horizontal alignment component 14 can be easily adjusted to adapt to different widths of printing materials, which enhances the versatility and adaptability of the feeding mechanism. At the same time, it can firmly fix the horizontal alignment component 14 to ensure that it will not loosen during operation.

[0036] Example 2: Figure 2-7 As shown, this is an improvement on the previous embodiment.

[0037] Specifically, the horizontal alignment component 14 includes an insert 1401, a sliding sleeve 1402 fixedly mounted on the outer surface of the insert 1401, a groove 1403 formed on the inner surface of the sliding sleeve 1402, and a sliding rod 1404 slidably connected to the inner surface of the groove 1403.

[0039] Specifically, there are two identical longitudinal alignment components 6 and transverse alignment components 14. The two longitudinal alignment components 6 and transverse alignment components 14 are symmetrically distributed about the center line of the tray 15. The advantage is that the symmetrical distribution design makes the alignment of the printing material more uniform and accurate, and can better ensure that the center position of the material in the longitudinal and transverse directions is aligned with the printing center of the printing press, further improving the printing quality and avoiding printing defects caused by material position deviation.

[0040] Working principle: During use, the slider 601 of the longitudinal alignment component 6 slides on the outer surface of the fixed post 5, driving the alignment rod 602 to move. The alignment rod 602 contacts the material to be printed on the tray 15. By pushing the alignment rod 602, the material to be printed is aligned in the longitudinal direction. After adjusting to the appropriate position, the insert rod 605 is inserted into the positioning slot 8 or the positioning slot 16 to fix the position of the longitudinal alignment component 6. The insert strip 1401 of the transverse alignment component 14 is inserted into the slot 11 of the mounting sleeve 10. The position of the transverse alignment component 14 is adjusted by moving the adjusting bolt 13 in the adjusting slot 12 to accommodate materials of different widths to be printed. After adjustment, tighten the adjusting bolt. With the bolt 13 fixed, the operator holds the handle 1405 and pushes or pulls the slide bar 1404. The slide bar 1404 slides in the groove 1403 of the slide sleeve 1402, driving the positioning seat 1406 and the alignment rod 1407 to perform a lateral alignment operation on the material to be printed. The slide seat 2 on the slide rail 1 supports the tray 15 and allows it to slide along the slide rail 1. The positioning frame 3, positioning rod 4 and other structures provide the installation and positioning foundation for the longitudinal and lateral alignment components 14. The two symmetrically distributed longitudinal alignment components 6 and lateral alignment components 14 work together to align the material to be printed placed on the tray 15 from the longitudinal and lateral directions, respectively, to ensure that the material enters the printing machine in the accurate position.
