Description

Technical Field

[0001] This utility model belongs to the field of printer technology, specifically relating to a dust collector, a body assembly, and a printer. Background Technology

[0002] A printer is a computer peripheral device that outputs electronic documents or images to paper or other media. It receives digital signals from a computer, mobile phone, or other device and uses printing technology to "print" physical copies of text, graphics, or photographs. There are various types of printers, such as line marker printers, label printers, and invoice printers.

[0003] In printing technologies such as wire marking machines, the media to be printed needs to be dust-removed before printing. However, in actual use, the dust removal effect of existing products still cannot meet expectations. Utility Model Content

[0004] The purpose of this application is to provide a dust collector, a body assembly, and a printer to solve the technical problem that existing printer products cannot achieve the expected dust removal effect on the media.

[0005] This application is achieved through the following means: In a first aspect, embodiments of this application provide a dust collector for use in a printer. The dust collector includes a mounting frame and two dust collector components. The dust collector components are flexible structural components. The two dust collector components are mounted on the mounting frame. Each of the two dust collector components has a first through hole for media to pass through, and the two dust collector components are arranged sequentially on the mounting frame along the media conveying path.

[0006] Secondly, embodiments of this application provide a body assembly, including the printer body and the dust collector provided in the first aspect embodiment, wherein the dust collector is installed on the body.

[0007] Thirdly, embodiments of this application provide a printer, including the body assembly provided in the second aspect embodiment.

[0008] The technical solution provided in this application can achieve the following beneficial effects: In this application, two dust collectors are provided, each with a first through-hole for the media to pass through. The media passes through the first through-hole, and the flexible structure of the dust collectors can clean the surface of the media. Simultaneously, the two dust collectors are arranged sequentially along the media conveying path, cleaning the media in turn, thus improving the cleaning effect. During the specific cleaning process, the dust collector that contacts the media first removes most of the dirt, while the dust collector that contacts the media later removes the remaining dirt, which helps improve the dust collector's dust removal effect on the media, correspondingly improving the printer's printing effect. Furthermore, the media passes through the dust collectors, and the dust collectors limit the media in the circumferential direction, fixing the relative position of the media and the printer.

Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Furthermore, in the claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following related objects are in an "or" relationship.

[0014] This application provides a dust collector 100, which is applied to a printer to pre-clean the media 200 to be printed in the printer, so as to ensure the printing effect of the printer on the media 200.

[0015] For reference Figure 1 and Figure 2 As shown, the dust collector 100 provided in this embodiment includes a mounting frame 110 and a dust collector component 120. The mounting frame 110 serves as the mounting base, facilitating the installation of the dust collector 100 onto the printer. The dust collector component 120, as the main component for cleaning the media 200, is a flexible structural component, facilitating dust removal and cleaning of the media 200 surface while avoiding damage to the media 200 surface. There are two dust collector components 120, both mounted on the mounting frame 110. Both dust collector components 120 have a first through hole 121 for the media 200 to pass through, as shown in the reference. Figure 3 and Figure 5 As shown, two dust removal components 120 are arranged sequentially on the mounting frame 110 along the conveying path of the medium 200.

[0016] During the dust removal process of medium 200, medium 200 passes through the first through hole 121. The cooperation between medium 200 and dust collector 100 can be referred to... Figure 6 As shown, the dust removal component 120 performs dust removal on the circumferential sidewalls of the medium 200. The two dust removal components 120 are arranged along the conveying path of the medium 200, allowing them to sequentially remove dust from the medium 200. The dust removal component 120 that contacts the medium 200 first removes most of the dirt, while the dust removal component 120 that contacts the medium 200 later further removes any remaining dirt from the surface of the medium 200. This improves the dust removal effect of the dust collector 100 on the medium 200, resulting in a better dust removal effect compared to existing dust collectors 100, and also correspondingly improves the printing effect of the printer on the medium 200.

[0017] In addition, the media 200 is disposed in the dust removal component 120, which limits the media 200 in the circumferential direction, thereby fixing the relative position of the media 200 and the printer.

[0018] The dust removal component 120 provided in this embodiment is a flexible structural component. The diameter of the first through hole 121 can be set to be less than or equal to the diameter of the medium 200, so that the dust removal component 120 can press against the surface of the medium 200, thereby improving the dust removal effect on the medium 200.

[0019] During the dust removal process of the medium 200, the medium 200 passes sequentially through the first through holes 121 of the two dust removal components 120. In some preferred embodiments, along the conveying direction of the medium 200, the diameter of the downstream first through hole 121 is larger than the diameter of the upstream first through hole 121. It can be understood that upstream and downstream are relative to the conveying of the medium 200; of the two first through holes 121, the first through hole 121 through which the medium 200 passes first is located upstream, and the first through hole 121 through which the medium 200 passes second is located downstream.

[0020] The medium 200 first passes through the smaller diameter first through hole 121. To accommodate the size of the medium 200, the first through hole 121 is more deformable, resulting in stronger pressure on the surface of the medium 200 and thus better removal of dirt from the surface of the medium 200. When the medium 200 passes through the dust collector 120, its surface is untreated and heavily soiled when it comes into contact with the upstream dust collector 120. By making the first through hole 121 of the upstream dust collector 120 even smaller, most of the dirt on the surface of the medium 200 can be removed. The downstream dust collector 120 removes the remaining small amount of dirt on the surface of the medium 200. The two dust collectors 120 work together to further improve the dust removal effect.

[0021] There are multiple ways to connect the dust collector 120 to the mounting frame 110, such as snap-fit, fastening, or adhesive bonding. Adhesive bonding makes the connection between the dust collector 120 and the mounting frame 110 more stable, simplifies their structure to some extent, avoids making them too complex, and is easy to operate, thus improving the production efficiency of the dust collector 100.

[0022] In some preferred embodiments of this application, reference may be made to Figure 2 As shown, the dust collector 120 has a plurality of slits 122 distributed circumferentially along the first through hole 121, and the slits 122 communicate with the first through hole 121. Due to the presence of multiple slits 122, the expandable size of the first through hole 121 is increased, allowing media 200 with larger diameters to pass through. The dust collector 100 can handle media 200 of various diameters, improving the flexibility of use of the dust collector 100.

[0023] In some embodiments provided in this application, reference can be made to Figure 4 As shown, the mounting frame 110 also includes a baffle 112, and the baffle 112 is provided with a second through hole 112a. The two dust collectors 120 are respectively located on both sides of the baffle 112. The presence of the baffle 112 increases the contact area between the dust collector 120 and the mounting frame 110, making the connection between the dust collector 120 and the mounting frame 110 more stable. Furthermore, the second through hole 112a provided on the dust collector 120 will not affect the normal conveying of the medium 200. In addition, when the medium 200 passes through the dust collector 120, the friction between the medium 200 and the dust collector 120 tends to drive the dust collector 120 to move. For the dust collector 120 located upstream, the baffle 112 also has a limiting effect, preventing it from moving towards the other dust collector 120 and maintaining its positional stability.

[0024] Preferably, the second through hole 112a and the two first through holes 121 are coaxially arranged, so that the medium 200 maintains a stable and consistent conveying direction. Furthermore, the radial dimension of the second through hole 112a is larger than the radial dimension of the medium 200, so as to avoid the medium 200 scraping against the inner wall of the second through hole 112a and causing damage to the surface of the medium 200.

[0025] The mounting frame 110 serves as the specific mounting structure for the dust collector 120. The mounting frame 110 can be a semi-enclosed structure or a fully enclosed structure. (See reference...) Figure 3 As shown, the mounting frame 110 is a ring-shaped structural component, and an mounting channel 111 is formed inside it. The dust removal component 120 is installed in the mounting channel 111, and the mounting frame 110 protects the circumferential sidewalls of the dust removal component 120.

[0026] When the mounting frame 110 also includes a baffle 112, the baffle 112 is located within the mounting channel 111, and the baffle 112 and the inner wall of the mounting channel 111 form a groove structure for mounting the dust collector 120, further improving the protective effect of the mounting frame 110 on the dust collector 120. In some preferred embodiments, it is necessary to limit the height of the dust collector 120 so that after the dust collector 120 is installed in the mounting channel 111, the axial surface of the dust collector 120 is flush with the axial surface of the mounting frame 110, avoiding the situation where part of the dust collector 120 is exposed outside the mounting channel 111, which would affect the protective effect of the mounting frame 110 on the dust collector 120.

[0027] For reference Figures 1 to 4 As shown, the outer peripheral sidewall of the mounting frame 110 is provided with a first snap-fit ​​protrusion 113, which is used to snap into the printer body 300 to fix the dust collector 100 to the body 300. The printer includes a top cover 400 and a body 300. The top cover 400 is rotatably connected to the body 300 and can cover and shield the body 300 to prevent external dust and impurities from falling into the body 300.

[0028] The dust collector 100 and the body 300 are connected by a snap-fit ​​mechanism. The mounting frame 110 has a frame structure, and the first snap-fit ​​protrusion 113 is located on the outer peripheral side wall of the mounting frame 110. During the installation of the dust collector 100 to the body 300, the first snap-fit ​​protrusion 113 is subjected to external pressure, which makes the mounting frame 110 more prone to deformation, thereby improving the ease of installation of the dust collector 100. At the same time, the snap-fit ​​mechanism between the dust collector 100 and the body 300 also makes it easier to disassemble and replace the dust collector 100.

[0029] In some embodiments, reference may be made to Figures 1 to 4As shown, the outer peripheral sidewall of the mounting frame 110 is also provided with a limiting protrusion 114. Along the assembly direction of the dust collector 100 and the printer body 300, the limiting protrusion 114 and the body 300 are limited and matched to determine the installation position of the dust collector 100 on the body 300, so as to avoid the situation that the conveying direction of the medium 200 passing through the dust collector 100 is deviated due to the offset of the installation position of the dust collector 100.

[0030] In some preferred embodiments, reference may be made to Figure 3 and Figure 4 As shown, the mounting frame 110 has an operating end 115 and an abutment end 116 positioned opposite each other. The operating end 115 is driven by external force, and the abutment end 116 is used to abut against the printer body 300. During the installation of the dust collector 100 onto the printer body 300, the operator presses the operating end 115 to drive the dust collector 100 to move until the abutment end 116 abuts against the printer body 300. When the mounting frame 110 is provided with a limiting protrusion 114, the abutment end 116 and the limiting protrusion 114 simultaneously abut against the printer body 300 to achieve limiting.

[0031] The abutment end 116 has an arc-shaped structure, and the center of the arc corresponding to the abutment end 116 is located on the axis of the first through hole 121. Because the abutment end 116 has an arc-shaped structure, even if the abutment end 116 rotates relative to the body 300, the position of the first through hole 121 corresponding to the center of the abutment end 116 will not change. This avoids the situation where the position of the first through hole 121 shifts due to an unexpected shift in the relative position of the abutment end 116 and the body 300, effectively ensuring the stability of the conveying direction of the medium 200 passing through the dust collector 100. It should be noted that it is best if the two first through holes 121 are coaxially arranged, so that the positions of the two first through holes 121 relative to the body 300 can be kept stable simultaneously.

[0032] This application provides a fuselage 300 component, which can be referred to as [reference needed]. Figures 7 to 10 As shown, the printer includes a printer body 300 and a dust collector 100 provided in any of the above embodiments, with the dust collector 100 mounted on the body 300.

[0033] With a first snap-fit ​​protrusion 113 provided on the outer peripheral side wall of the mounting frame 110, the body 300 is provided with a mounting groove 310 for mounting the dust collector 100, and the groove wall of the mounting groove 310 is provided with a second snap-fit ​​protrusion 320, as can be seen from [reference]. Figure 12 and Figure 13As shown, the second snap-fit ​​protrusion 320 is located on the insertion path of the first snap-fit ​​protrusion 113. The second snap-fit ​​protrusion 320 is configured to deform under the pressure of the first snap-fit ​​protrusion 113 during the insertion of the dust collector 100 into the mounting slot 310, so that the first snap-fit ​​protrusion 113 passes over at least part of the second snap-fit ​​protrusion 320, and the two mutually limit each other to prevent the dust collector 100 from dislodging from the mounting slot 310.

[0034] The body 300 and the dust collector 100 are engaged through the cooperation of the first locking protrusion 113 and the second locking protrusion 320. During the insertion of the dust collector 100 into the mounting slot 310 of the body 300, after the first locking protrusion 113 and the second locking protrusion 320 come into contact, they deform under external force, allowing the first locking protrusion 113 to move partially or completely below the second locking protrusion 320. When it is necessary to remove the dust collector 100 from the body 300, the operator can forcefully pull the dust collector 100 outwards. The first locking protrusion 113 and the second locking protrusion 320 will then press against each other again, allowing the first locking protrusion 113 to pass over the second locking protrusion 320 and move above it, releasing the constraint between the first locking protrusion 113 and the second locking protrusion 320.

[0035] In some preferred embodiments, reference may be made to Figure 11 As shown, two inclined surfaces are provided on the second snap-fit ​​protrusion 320. One inclined surface is used to guide the first snap-fit ​​protrusion 113 to move downward toward the second snap-fit ​​protrusion 320, so that the dust collector 100 can be inserted into the mounting slot 310. The other inclined surface is used to guide the first snap-fit ​​protrusion 113 to move upward toward the second snap-fit ​​protrusion 320, so that the dust collector 100 can be removed from the mounting slot 310.

[0036] The second latching protrusion 320 can be fully engaged with the first latching protrusion 113 for limiting, or only a portion of the second latching protrusion 320 can be engaged with the first latching protrusion 113 for limiting. (See reference.) Figure 11 As shown, the end of the second snap-fit ​​protrusion 320 near the bottom of the mounting groove 310 is fixed to the groove wall of the mounting groove 310, while the end of the second snap-fit ​​protrusion 320 away from the bottom of the groove is used to limit the engagement with the first snap-fit ​​protrusion 113. There is a gap between this end and the groove wall of the mounting groove 310. This gap can serve as a space for the movement and deformation of the second snap-fit ​​protrusion 320, making it easier for the second snap-fit ​​protrusion 320 to deform and easier for the dust collector 100 to be assembled into the mounting groove 310.

[0037] In some embodiments of this application, the fuselage 300 is further provided with a guide surface 330, which is disposed adjacent to the mounting groove 310, as can be referred to. Figure 12 and Figure 13As shown, the guide surface 330 is located on the output side of the medium 200 corresponding to the dust collector 100. The guide surface 330 is used to cooperate with the medium 200 corresponding to the dust collector 100 to adjust the moving direction of the medium 200, so that the medium 200 moves away from the bottom of the mounting groove 310. That is, after the medium 200 moves from the dust collector 100 to the guide surface 330, it contacts the guide surface 330. The guide surface 330 guides the medium 200 to move upward, so as to avoid excessive friction between the medium 200 and the surface of the machine body 300, which would affect the quality of the medium 200, and also prevent the surface of the medium 200 from re-adhering dust during the friction with the surface of the machine body 300.

[0038] In some other embodiments of this application, the downstream first through hole 121 along the conveying direction of the medium 200 is closer to the opening of the mounting groove 310 than the upstream first through hole 121. During the conveying process of the medium 200 passing through the two first through holes 121 sequentially, because the downstream first through hole 121 is higher, the moving direction of the medium 200 can be appropriately changed, giving the medium 200 a tendency to rise, and also preventing the medium 200 from rubbing against the surface of the housing 300. The conveying direction of the medium 200 can be referenced... Figure 10 The dashed arrows in the diagram indicate the direction.

[0039] This application also provides a printer, the overall structure of which can be referred to... Figure 7 and Figure 9 As shown, the printer includes the body assembly provided in any of the above embodiments.

[0040] It should be noted that, in this document, the term "comprising" or any other variation thereof is intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0041] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
