[0020] The following detailed description is presented to aid the reader in gaining a comprehensive understanding of the methods, apparatuses, and / or systems described herein. However, various changes, modifications, and equivalents can be used, and thus particular embodiments described herein are not intended as being exhaustive of what the present disclosure can provide. For example, although processes are described with regard to particular operational flows, various changes can be made within the scope of the present disclosure. For example, the order of operations can be changed, or certain operations can be performed in parallel, or operations can be added or omitted. Moreover, although description of features can be directed to particular embodiments, one skilled in the art will understand that alterations and / or

[0021] The features described herein can be implemented in different forms and should not be construed as limited to the examples described herein. Rather, these examples are provided as illustration of some of the many possible forms in which the methods, apparatuses, and / or systems described herein can be implemented.

[0022] Throughout the specification, when an element (such as a layer, region, or substrate) is referred to as being "on" another element, "connected to" another element, "coupled to" another element, "adjacent to" another element, "on top of" another element, or "covering" another element, it can be directly on, connected to, coupled to, adjacent to, on top of, or covering the other element, or one or more other elements can be interposed therebetween. In contrast, when an element is referred to as being "directly on," "directly connected to," "directly coupled to," "directly adjacent to," "directly on top of," or "directly covering" another element, there are no other elements interposed therebetween.

[0023] As used herein, the term "and / or" includes any and all combinations of one or more of the associated items.

[0024] Although terms such as "first," "second," and "third" can be used herein to describe various elements, components, regions, layers, or sections, these elements, components, regions, layers, or sections should not be limited by these terms. Rather, these terms are only used to distinguish one element, component, region, layer, or section from another element, component, region, layer, or section. Thus, the first element, component, region, layer, or section referred to in the examples described herein can also be referred to as the second element, component, region, layer, or section without departing from the teachings of the examples.

[0025] For ease of description, spatial terms, such as "on", "upper", "below", and "lower" can be used herein with respect to the orientation of one element relative to another element as shown in the drawings. Such spatial terms are intended to encompass different orientations of the device in use or operation, in addition to the orientation depicted in the drawings. For example, if the device in the drawings is turned over, then a component that was described as on or above other components would then be oriented on or below the other components.

[0026] Therefore, the term "on" encompasses both "on" and "under" depending on the spatial orientation of the device. The device can be oriented in other ways (e.g., rotated 90 degrees or at other orientations) and the spatial terms used herein will be interpreted accordingly.

[0027] The terminology used herein is for the purpose of describing various examples only and is not intended to be limiting of the disclosure. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. The terms "comprises", "comprising", "includes", "including" and "has", "having" as used herein, are specifically intended to be construed as open-ended terms (i.e., the terms do not exclude the presence of other elements or steps).

[0028] Variations in shapes that are shown in the drawings can occur as a result of manufacturing processes and / or tolerances. Therefore, the examples described herein are not limited to the precise shapes shown in the drawings, but include variations in shapes that occur as a result of manufacturing processes.

[0031] Example One

[0032] As Figure 1 , Figure 2 , Figure 3As shown, the dust removal mechanism for a printing press proposed in this utility model includes a mounting frame 1, a motor 2, and a suction hood 4. The mounting frame 1 has two sets of slide rails 101 inside. The output end of the motor 2 is equipped with a lead screw 201. A movable seat 3 is slidably arranged outside the mounting frame 1. An ultrasonic generator 301 is installed on one side of the front of the movable seat 3. The suction hood 4 is fixedly installed on the front of the movable seat 3. A brush 401 is installed on the front of the suction hood 4. Air filters 402 are installed at both ends of the suction hood 4, and a fan 403 is arranged outside the air filters 402.

[0033] The working principle of the dust removal mechanism of the printing press based on Embodiment 1 is as follows: The brush 401 in this device is made of a special material, which has the characteristics of wear resistance and ink corrosion resistance. Driven by the motor 2, the brush 401 can automatically reciprocate to clean the print head. At the same time, the external control unit controls the fan 403 to be powered on and run, so that the suction hood 4 generates negative pressure. The dust swept down will enter from the inside of the brush 401 and be filtered by the air filter element 402 under the action of the fan 403 to prevent secondary pollution. During the cleaning process, the ultrasonic generator 301 is powered on and runs. The ultrasonic generator 301 emits ultrasonic waves, which cause dust and stubborn stains to be peeled off from the print head under the action of ultrasonic waves. It can thoroughly remove dust and impurities from the surface of the print head, ensuring printing quality and efficiency. This device does not require the use of chemical cleaning agents, reducing environmental pollution. It can thoroughly remove ink, dust and other impurities from the print head and ensure printing quality.

[0034] Example 2

[0035] like Figure 1 , Figure 3 As shown, the dust removal mechanism for a printing machine proposed in this utility model, compared with Embodiment 1, further includes: a slider 302 extending through the top and bottom of the movable seat 3, a screw hole 303 inside the movable seat 3, the slider 302 being slidably connected to the slide rail 101, the screw hole 303 being threadedly engaged with the lead screw 201, the fan 403 being threadedly installed with the air filter element 402, and two sets of fixing feet 102 being fixedly installed on both sides of the back of the mounting bracket 1.

[0036] In this embodiment, as Figure 1 As shown, the slider 302 provides a through-hole position for the slide rail 101, and the screw hole 303 provides a through-hole position for the lead screw 201, allowing the movable seat 3 to be installed with the internal components of the mounting bracket 1; as Figure 1As shown, because the sliding block 302 is in sliding connection with the sliding rail 101, the stability of the moving seat 3 when moving outside the mounting frame 1 can be improved, and through the engagement of the screw hole 303 and the screw thread of the screw rod 201, the moving seat 3 can be moved when the screw rod 201 is rotated by the motor 2, the motor 2 is controlled by an external control unit, the reciprocating rotation of the motor 2 is controlled, and the moving seat 3 is reciprocatingly moved; as Figure 3 As shown, because the fan 403 is in threaded installation with the air filter element 402, the fan 403 can be disassembled after being used for a period of time to clean and maintain the air filter element 402, so that the filtering performance of the air filter element 402 on dust can be maintained; as Figure 1 As shown, the device can be installed at a specified position through the fixing foot 102, so that the device can be installed at a position that needs to be cleaned by the printer.

[0037] The above specific embodiments are only several preferred embodiments of the utility model, based on the technical scheme of the utility model and the related inspiration of the above embodiments, the person skilled in the art can make various alternative improvements and combinations on the above specific embodiments.
