Description

Technical Field

[0001] The utility model relates to the technical field of plate-mounting by plate rollers, in particular to a plate-mounting driving device which is suitable for different plate rollers. Background Art

[0002] Flexographic printing press is a printing equipment with many advantages, including its flexibility, easy maintenance and high-speed operation capability. It is suitable for a variety of printing materials, can produce high-quality printing, and is easy to operate, reducing the cost of use.

[0003] At present, when a flexible printing plate made of resin (called flexographic plate) is attached to the surface of a plate roller, manual plate mounting is mostly adopted. Manual plate mounting has the problems of poor mounting accuracy and low mounting efficiency. To solve the above problems, some automatic plate mounting machines are used instead of manual plate mounting. However, there are many types of plate rollers with mechanical structures on the market. The mainstream plate rollers are the following two types:

[0004] First, the plate roller is hollow inside, and a transmission shaft needs to penetrate into the plate roller to drive the plate roller to rotate; there is no completely unified standard specification for the size of the hollow part;

[0005] Second, the center of the plate roller has a fixed shaft, and limit rings are located at both ends of the shaft according to the size of the plate roller; a driving gear is set at one end of the plate roller, and the plate roller is driven to rotate by the driving motor driving the gear;

[0006] The above two types of plate rollers need to be driven by different drive devices. However, even if the plate rollers are of the same structure, the size specifications will be inconsistent because they are purchased from different equipment manufacturers; the same plate mounter cannot take all of them into account. There are automatic plate mounters for the above two types of plate rollers on the market. At present, for enterprises, considering the equipment purchase period and cost issues, the equipment they may purchase may have several models from several suppliers, which will result in a variety of different specifications of plate rollers for the production of different products. However, for small and medium-sized enterprises, purchasing multiple devices is costly and increases the floor space.

[0007] In view of this, the inventor specially designed a plate mounting drive device that is suitable for different plate rollers, and this case was thus generated. Utility Model Content

[0053] Loosen the first fixing member 424 and the second fixing member 52, adjust the movable limit plate 51 and the sleeve 22 according to the length of the plate roller to adjust the spacing of the sleeve 22. After the adjustment is completed, tighten the first fixing member 424 and the second fixing member 52, place the plate roller above the two driving wheels 20, and align and place the flexographic plate on the plate roller. Then, drive the cylinder 70 to drive the plate pressing rubber roller 60 to press the flexographic plate and the plate roller. At the same time, in order to adapt to plate rollers with different outer diameters, the two support plates 11 can be slidably connected to the frame 10. Specifically, a vertical slide rail is set on the frame 10, and a slider matched with the slide rail is fixedly set on the support plate 11. At the same time, a lifting cylinder can be set on the frame 10 to drive the two support plates 11 to slide along the vertical direction.
