Description

Technical Field

[0001] The utility model relates to the field of pressing components, and particularly relates to a pressing component for an inkjet printer. Background Art

[0002] An inkjet printer is a device that uses software control to perform non-contact marking on products. Generally, it refers to continuous inkjet technology, abbreviated as CIJ. An inkjet printer operates on the principle of deflecting charged ink particles by a high-voltage electric field to spray patterns, characters, and numbers on the surfaces of various objects. It is a high-tech product integrating mechanical and electrical integration. The products are widely used in the food industry, cosmetics industry, pharmaceutical industry, parts processing industries such as automobiles, wire and cable industries, aluminum-plastic pipe industries, tobacco and alcohol industries, and other fields, and can be used for spraying production dates, batch numbers, barcodes, trademark patterns, anti-counterfeiting marks, and Chinese characters.

[0003] In the prior art, during the actual use of the pressing component on the existing inkjet printer, when the inkjet printer performs inkjet printing on flexible items, due to the uneven surface of the flexible items and the presence of many wrinkles on the surface of the flexible items, the pressing component cannot flatten the wrinkles on the surface of the flexible items, resulting in the patterns sprayed on the surface of the flexible items being unclear and discontinuous, thereby reducing the inkjet printing effect of the inkjet printer on flexible items.

The drive motor 10 is fixedly connected to the rear end of the concave plate 5, and the output end of the drive motor 10 is fixedly connected to the first rotating rod 9. The two moving plates 11 are respectively movably connected to the bidirectional adjustment screw 8 through the threaded holes 12 on the front end walls, and the electric push rod 15 is fixedly connected to the bottom end of the mounting plate 14 on the right side of the moving plate 11. The L-shaped connecting rod 16 is fixedly connected to the output end of the electric push rod 15, and the pressing roller 19 is movably connected to the left end of the L-shaped connecting rod 16 through the second rotating rod 20 at the right end.

[0021] As Figure 1 - Figure 4As shown, in this embodiment, in order to improve the inkjet printing effect of the inkjet printer body 2 when printing on flexible articles through the pressing mechanism 4, the concave plate 5 is fixedly installed at the top of the right side wall of the workbench 1, and rotating holes 6 are respectively formed in the front and rear end walls of the concave plate 5. A limiting sliding groove 7 is formed in the left side wall of the concave plate 5. The front and rear ends of the bidirectional adjustment screw rod 8 are respectively fixedly installed with a first rotating rod 9, and the first rotating rod 9 is movably installed in the rotating hole 6. The driving motor 10 is fixedly installed on the rear end wall of the concave plate 5, and the output end of the driving motor 10 is fixedly installed with the first rotating rod 9 at the rear end. A threaded hole 12 is formed in the front end wall of the moving plate 11 and is threadedly connected with the bidirectional adjustment screw rod 8 through the threaded hole 12. A limiting slider 13 is fixedly installed on the left side wall of the moving plate 11, and the limiting slider 13 is movably installed in the limiting sliding groove 7. An installation plate 14 is also fixedly installed at the top of the right side wall of the moving plate 11.

[0022] The specific working principle of the pressing mechanism 4 in cooperation with the inkjet printer body 2 is as follows: Place the flexible article to be inkjet-printed on the top surface of the workbench 1 and directly below the inkjet head 3, and make the pressing rollers 19 symmetrically arranged on the top surface of the workbench 1 located above the flexible article. Turn on the electric push rod 15 installed on the bottom surface of the mounting plate 14 on the right side of the moving plate 11. The output end of the electric push rod 15 will retract, driving the L-shaped connecting rod 16 installed at the top to move downward. During the downward movement of the L-shaped connecting rod 16, the pressing roller 19 at the left end will be driven to move downward and press tightly on the surface of the flexible article. Then, turn on the driving motor 10 installed at the rear end of the concave plate 5 on the right side of the workbench 1. The driving motor 10 will drive the first rotating rods 9 at the front and rear ends of the bidirectional adjustment screw rod 8 at the output end to rotate in the rotation holes 6 opened on the front and rear end walls of the concave plate 5. The first rotating rod 9 will drive the bidirectional adjustment screw rod 8 to rotate within the concave plate 5. When the bidirectional adjustment screw rod 8 rotates, the symmetric moving plates 11 will respectively perform relative movement operations along the bidirectional adjustment screw rod 8 through the threaded holes 12 opened on the front end walls. During the movement, the limit sliding blocks 13 installed on the left side walls of the moving plates 11 will slide within the limit sliding openings 7 opened on the left side wall of the concave plate 5. At this time, the symmetric pressing rollers 19 will roll in opposite directions while pressing tightly on the surface of the flexible article. When rolling, the second rotating rod 20 installed at the right end of the pressing roller 19 will rotate within the bearing 18 installed in the installation hole 17 opened at the left end of the L-shaped connecting rod 16, so as to achieve the purpose of smoothing the wrinkles on the surface of the flexible article, ensuring that the surface of the flexible article is relatively smooth during inkjet printing. Furthermore, by using the pressing mechanism 4 in cooperation with the inkjet printer body 2, the inkjet printing effect of the inkjet printer on the flexible article can be improved. Finally, the inkjet printer body 2 completes the inkjet printing operation on the surface of the flexible article through the inkjet head 3.
