Description
Technical Field
[0001] The utility model relates to the technical field of ink-stirring roller gears, in particular to an ink-stirring roller gear of a printing machine. Background Art
[0002] Modern printing presses are generally composed of mechanisms such as plate loading, inking, embossing, and paper feeding. Ink rollers, ink-splitting rollers, and gears are the most common structures in printing machinery. The ink-splitting roller provides power for the ink roller. Among all the ink rollers, only the ink-splitting roller is the active roller. Driven by the gear, the ink-splitting roller drives the other rubber roller and the plate cylinder to roll synchronously under the action of friction, ensuring that the plate roller can transfer the ink to the printing plate synchronously. At the same time, the ink-splitting roller can also better spread the ink evenly.
[0003] The teeth of the ink roller gear of a printing machine are usually fixedly connected to the toothed disc and cannot be disassembled. When the teeth are damaged and cannot work, the entire gear is usually disassembled and replaced, which increases the maintenance cost of the printer. Therefore, an ink roller gear of a printing machine is proposed to address the above problem. Utility Model Content

[0022] Unless otherwise specifically stated, the relative arrangement, numerical expressions and numerical values of the parts and steps described in these embodiments do not limit the scope of the utility model. At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the accompanying drawings are not drawn according to the actual proportional relationship. The technology, methods and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be regarded as a part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once a certain item is defined in one drawing, it does not need to be further discussed in subsequent drawings.
[0023] In the description of the present utility model, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present utility model; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.
[0024] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.
[0025] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the utility model.
