Abstract
Description
Technical Field
[0001] This utility model relates to the field of digital printing machine technology, specifically to a camera mechanism and its digital printing machine. Background Technology
[0002] Digital inkjet printers are high-tech products that have gradually emerged with the continuous development of computer technology, integrating mechanical, computer electronic, and information technologies. The core of this technology is the conversion of image data from a computer into printing instructions, which are then precisely sprayed onto the fabric surface through the printhead of the inkjet printer to form the desired pattern.
[0003] Existing digital inkjet printers include a frame, a conveyor mechanism mounted on the frame, an inkjet printing device, and several cameras. The cameras capture digital images of the printing media and input the captured digital images into a computer, which then controls the inkjet printing device to print the media.
[0004] However, the image captured by the camera on the printing medium has a significant impact on printing accuracy. Specifically, in dim lighting conditions, the camera may not receive enough light, resulting in poor image quality (clarity). This leads to inaccurate edge recognition of the pattern during inkjet printing, thus reducing printing accuracy.
[0005] Therefore, there is an urgent need to provide a camera mechanism that can provide supplementary lighting for the camera and improve the image acquisition effect. Utility Model Content

A second mounting hole for fixing the camera is provided on the limiting plate. The opening direction of the second mounting hole is perpendicular to the opening direction of the first mounting hole.
[0013] Optionally, a hollow protective shell is also installed on the outer wall of the mounting block, and the camera is located inside the hollow protective shell.

[0020] Compared with the prior art, this utility model provides a camera mechanism and its digital printing machine, which has the following beneficial effects:
[0021] This camera mechanism and its digital printing machine, through the setting of a supplementary light, and with the camera movably mounted on the supplementary light mounting structure, allow for free adjustment of the angle between the light and the fabric surface.

[0035] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, illustrates the present invention. Numerous specific details are set forth in the description below to provide a thorough understanding of the invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0036] The camera mechanism and digital printing machine of this application can be applied to occasions in digital printing machines where a camera is needed for shooting, and of course, it can also be used in other similar application scenarios. The following is a detailed description of the camera mechanism and digital printing machine.
[0037] Example 1
[0038] See appendix Figure 1 — Figure 8 The diagram shows a preferred embodiment of a camera mechanism according to this application. The camera mechanism is mounted on the inkjet mechanism of a digital printing machine and moves synchronously with the inkjet mechanism. The camera mechanism includes a camera 3, a supplementary light 4 that illuminates the printing medium to provide supplementary lighting for the camera 3, a camera mounting structure 1 for mounting the camera 3 on the inkjet mechanism, and a supplementary light mounting structure 2 for mounting the supplementary light 4 on the inkjet mechanism.
[0039] This utility model provides installation and adjustment for camera 3 through the camera mounting structure 1; camera 3 is used to scan the printing medium; supplementary light mounting structure 2 provides installation conditions for supplementary light 4; supplementary light 4 is used to irradiate the fabric medium and supplement the light captured by camera 3.
[0040] See appendix Figure 5 — Figure 8As shown in this invention, on the cross-section of the printing medium, the illumination direction of the supplementary light 4 forms an obtuse angle with the printing surface of the printing medium, with the opening facing the camera 3. This angle ensures that the light generated by the supplementary light 4 can illuminate the fabric medium, and the illuminated area is located within the scanning area of the camera 3, thereby improving the image acquisition effect of the camera and improving the printing accuracy.
[0041] See appendix Figure 5 — Figure 8 As shown, in this utility model, the minimum distance between the supplementary light 4 and the printing medium is less than or equal to the minimum distance between the camera 3 and the printing medium, and the angle between the illumination direction of the supplementary light 4 and the surface of the printing medium can be adjusted by the supplementary light mounting structure 2.
[0042] This invention compares the distance between the supplementary light 4 and the surface of the printing medium with the distance between the camera 3 and the connector 5 to ensure that the supplementary light 4 can provide supplementary lighting to the fabric medium and increase the light intake of the camera 3. By adjusting the angle of the supplementary light 4, the angle between the supplementary light 4 and the fabric medium can be changed, allowing the supplementary light 4 to be adjusted according to the reflectivity of the fabric, thus avoiding overexposure due to excessive light intake of the camera 3 caused by excessive fabric reflection.
[0043] See appendix Figure 2 — Figure 4 As shown, in this utility model, the camera mounting structure 1 includes a mounting block 11 mounted on the inkjet mechanism 200, a groove 12 provided on the mounting block 11, a connecting mounting hole 13 provided on the top surface of the mounting block 11, and a first mounting hole 14 provided on the side of the mounting block 11 for mounting the camera 3. It should be noted that the connecting mounting hole 13 can be a round hole or an oblong hole, which facilitates the horizontal adjustment of the camera 3 and ensures that the supplementary lighting area of the supplementary light 4 is located within the shooting area of the camera 3.
[0044] This utility model provides installation conditions for the camera 3 through the setting of the mounting block 11; the setting of the groove 12 facilitates the operator to fix the mounting block 11 on the inkjet mechanism 200; the setting of the connecting mounting hole 13 provides installation conditions for the mounting block 11, and the mounting block 11 can be installed on the inkjet mechanism 200 by bolting through the connecting mounting hole 13; the setting of the first mounting hole 14 provides installation conditions for the camera 3, and the camera 3 can be installed on the side of the mounting block 11 by bolting through the first mounting hole 14.
[0045] See appendix Figure 2 — Figure 4As shown, in this utility model, a limiting plate 111 is provided on the side of the mounting block 11, and a mounting groove 112 is formed between the two limiting plates 111. The camera 3 is located in the mounting groove 112. A second mounting hole 113 for fixing the camera 3 is provided on the limiting plate 111. The opening direction of the second mounting hole 113 is perpendicular to the opening direction of the first mounting hole 14.
[0046] This invention uses a limiting plate 111 to limit both ends of the camera 3, ensuring the accuracy of the camera 3's position on the mounting block 11. A second mounting hole 113 connects the side of the camera 3 to the limiting plate 111. Since the opening direction of the second mounting hole 113 is perpendicular to the opening direction of the first mounting hole 14, connecting and limiting adjacent vertical surfaces of the camera 3 through the first mounting hole 14 and the second mounting hole 113 ensures that the plane of the area captured by the camera 3's lens is parallel to the horizontal plane, thus ensuring that the image captured by the camera 3 will not be distorted.
[0047] See appendix Figure 2 — Figure 4 As shown, in this utility model, a hollow protective shell 114 is installed on the outer wall of the mounting block 11, and the camera 3 is located inside the hollow protective shell 114. By installing the camera 3 on the outer wall of the mounting block 11, the camera 3 can be protected to prevent the camera 3 from being damaged by collisions during operation, thus avoiding problems such as adjustment of the shooting angle of the camera 3, affecting the shooting accuracy, or even damage to the camera 3.
[0048] See appendix Figure 5 — Figure 8 As shown, in this utility model, the fill light mounting structure 2 includes a mounting post 21 mounted on the inkjet mechanism 200 and a mounting frame 22 mounted on the mounting post 21, wherein the fill light 4 is mounted inside the mounting frame 22.
[0049] This utility model provides an installation position for the mounting frame 22 through the setting of the mounting column 21, and at the same time, the installation height of the mounting frame 22 can be lower than the installation height of the camera 3. The mounting frame 22 is used to provide an installation position for the supplementary light 4, and at the same time, it protects the supplementary light 4 and allows the supplementary light 4 to be installed movably, so that the angle of the light from the supplementary light 4 shining on the fabric can be adjusted. While providing supplementary lighting for the camera 3, it reduces light reflection and reduces overexposure caused by the camera 3 when shooting.
[0050] See appendix Figure 5 — Figure 8As shown, in this utility model, the mounting frame 22 is provided with a rotating hole 221, and a rotating column 222 movably connected to the supplementary light 4 is installed in the rotating hole 221; wherein, the inner wall of the mounting frame 22 is provided with an arc-shaped groove 223, the center of the arc-shaped groove 223 coincides with the center of the rotating hole 221, the supplementary light 4 is provided with a guide column 224 corresponding to the arc-shaped groove 223, and a locking member 225 is installed on the guide column 224. The rotating hole 221 is a blind hole, the arc-shaped groove 223 is a blind groove, and both the rotating hole 221 and the arc-shaped groove 223 are provided on the inner wall of the mounting frame 22. The mounting column 21 is provided with a third mounting hole 211 for mounting the mounting frame 22; it should be noted that in this application, the mounting frame 22 is composed of multiple plates connected to each other.
[0051] This invention provides installation conditions for the rotating column 222 and rotation conditions for the fill light 4 through the rotating hole 221, allowing the fill light 4 to rotate around the rotating column 222. The arc groove 223, in conjunction with the guide column 224, guides and limits the rotation of the fill light 4. Since the center of the arc groove 223 coincides with the center of the rotating hole 221, it effectively ensures that the guide column 224 can move around the rotating column 222 within the arc groove 223, thereby adjusting the angle of the fill light 4. The locking component 225 is used to lock the guide column 224, fixing the angle of the fill light 4 after it is adjusted to the specified angle, ensuring that the angle of the fill light 4 will not be adjusted during printing, thus guaranteeing the shooting effect and printing effect. It should be noted that the locking component 225 can be a hand-tightened nut, hand-tightened bolt, etc.
[0052] See appendix Figure 1 — Figure 9 As shown, this utility model also provides a digital printing machine, including a printing machine body 100 and an inkjet mechanism 200 installed on the printing machine body 100. The inkjet mechanism 200 is equipped with the aforementioned camera mechanism. It should be noted that the fabric medium passes through the camera mechanism and then through the inkjet mechanism 200 during the movement process.
[0053] Example 2
[0054] See appendix Figure 10 As shown, the difference between this embodiment and the above embodiment is that in this embodiment, a connector 5 is installed on the camera mounting structure 1 and the fill light mounting structure 2. The connector 5 is installed on the inkjet mechanism 200 and can be a connecting plate.
[0055] In this embodiment, the camera 3 and the fill light 4 are connected and installed through the setting of connector 5. In the subsequent installation process, it is only necessary to install connector 5 on inkjet mechanism 200, which improves installation efficiency.
[0056] Example 3
[0057] See appendix Figure 11 As shown, the difference between this embodiment and the above embodiment is that, in this embodiment, the arc-shaped groove 223 provided on the inner wall of the mounting frame 22 is a through groove, and the rotating hole 221 is a through hole.
[0058] In this embodiment, by having both the arc-shaped groove 223 and the rotating hole 221 penetrate the mounting frame 22, the mounting frame 22 can be integrally machined, which improves the strength of the mounting frame 22, facilitates the processing of the mounting frame 22, and allows the locking member 225 to be located on the outer wall of the mounting frame 22 to facilitate the adjustment of the angle of the supplementary light 4.
[0059] Example 4
[0060] See appendix Figure 12 As shown, the difference between this embodiment and the above embodiment is that, in this embodiment, the third mounting hole 211 is an oblong hole.
[0061] In this embodiment, by setting the third mounting hole 211 as an oblong hole, the mounting frame 22 can move along the oblong hole, and the mounting height of the mounting frame 22 can be adjusted. This ensures that after the supplementary light 4 is adjusted, the area illuminated by the supplementary light 4 is located directly below the camera 3, thereby further enhancing the supplementary lighting effect, improving the shooting effect of the camera 3, and improving the printing accuracy.
[0062] The above embodiments are illustrative of this application and are not intended to limit this application. Any simple modifications to this application are within the protection scope of this application.
