Description

Technical Field

[0001] The utility model relates to a pad printing mechanism and a handicraft pad printer thereof. Background Art

[0002] In modern handicraft production, pad printing technology is a widely used printing method, often used for printing complex patterns and texts on the surfaces of various materials. One of the core components of a pad printer is the pad printing mechanism, whose function is to transfer ink from the printing plate to the surface of the handicraft through a rubber head. However, there are some technical problems in the actual operation of existing pad printers, especially in the coordinated work between the scraper and the rubber head during the pad printing process.

[0003] Specifically, the design requirement of the pad printing mechanism of traditional pad printers is that the scraper scrapes back and forth at the ink-adding position of the rubber head during the process of the rubber head reaching the position of the handicraft for pad printing, so as to ensure that the rubber head can evenly pick up ink and prepare for the subsequent pad printing process. This process requires the movements of the scraper and the rubber head to be highly synchronized to avoid uneven ink distribution or a decline in printing quality. However, in actual use, the programs of the movements of the scraper and the rubber head often malfunction, resulting in the inability of the two to move synchronously. Such malfunctions may stem from various factors such as errors in the mechanical control system, improper programming, or equipment wear.

[0004] The occurrence of program malfunctions not only affects the accuracy and quality of pad printing, but may also lead to the interruption of the production process and reduce production efficiency. In addition, frequent malfunctions will increase the equipment maintenance cost and the operation burden of workers. In order to ensure the stability and efficiency of the pad printing process, it is urgent to improve the existing pad printing mechanism.

[0005] To solve the above problems, this application proposes a new design of the pad printing mechanism, aiming to reduce the occurrence of program malfunctions and improve the reliability and efficiency of the pad printing process by optimizing the coordinated control of the scraper and the rubber head.

Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0021] In the description of the present utility model, "a plurality of" means two or more unless otherwise specifically defined. In the present utility model, unless otherwise clearly specified and defined, terms such as "installed", "connected", "connected to", "fixed" and other terms should be understood in a broad sense.

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0022] The present utility model will be further described in detail below with reference to the drawings.

[0023] As Figure 1 shown, a pad printing mechanism includes a frame 1. A guide rail 2 is provided in the middle of the frame 1. A rubber seat 3 is slidably connected to the guide rail 2. The rubber seat 3 slides horizontally on the guide rail 2. A driving cylinder 4 is provided at the top of the rubber seat 3. An output shaft 5 is provided at the bottom of the driving cylinder 4. The output shaft 5 is connected to a rubber head 6. A cylinder (not shown in the figure) for pushing the rubber seat 3 to slide is provided in the frame 1 within the rubber seat 3. During use, the rubber seat 3 is driven by the cylinder to move above the handicraft. Then, under the action of the driving cylinder 4, the rubber head 6 moves downward, and the rubber head 6 performs printing treatment on the handicraft.

[0024] The core technical solution of this application is as follows:

[0025] As Figure 2 、 Figure 3 、 Figure 4As shown in the figure, in order to reduce the programming steps and improve the overall operation stability, a driving rod 7 is fixedly connected to one side of the rubber base 3 in this application. A gear 8 is engaged below the driving rod 7. A rotating shaft is fixedly connected to the middle of the gear 8. The rotating shaft is connected to the frame 1 by a bearing. One end of the rotating shaft is connected to a turntable 10. Among them, a connecting rod 11 is hinged at the edge position of the turntable 10. The connecting rod 11 is hinged to a connecting rod 12. The connecting rod 12 is hinged to a tool rest 13. A scraping knife 14 is arranged at the bottom of the tool rest 13. A positioning rod 15 is connected to one side of the scraping knife 14. The positioning rod 15 passes through the frame 1 and is used to limit the moving direction of the scraping knife 14.

[0026] Correspondingly, an ink tray 9 is correspondingly arranged at the bottom of the scraping knife 14. Corresponding inks of corresponding colors are added to the ink tray 9. And corresponding patterns are arranged at the end of the ink tray 9 corresponding to the shape to be printed. The inks fill the patterns and facilitate the rubber head 6 to pick up the ink.

[0027] As described above, when the rubber base 3 slides so that the rubber head 6 moves out of the ink tray 9 and enters above the handicraft, the rubber head 6 moves down to print the handicraft under the action of the driving cylinder 4. In this process, the driving rod 7 moves Figure 1 to the left side. When the driving rod 7 moves, it drives the gear 8 to rotate, and then the rotating shaft rotates. The rotating shaft drives the turntable 10 to rotate. When the turntable 10 rotates, the connecting rod 11 and the connecting rod 12 make reciprocating motions, thereby driving the scraping knife 14 to reciprocate back and forth in the ink tray 9 once, so that the pattern is refilled with ink.

[0028] Correspondingly, when the rubber base 3 slides so that the rubber head 6 resets, the scraping knife 14 also reciprocates back and forth in the ink tray 9 once, thereby ensuring the uniformity of the ink and improving the printing effect. When the rubber head 6 moves above the pattern, the rubber head 6 contacts the pattern under the action of the driving cylinder 4, adsorbs the pattern ink and then repeats the above printing process.

[0029] Under the above settings, the movement processes of the rubber head 6 and the scraping knife 14 can be synchronized, reducing the programming process and improving the stability of the overall working process, with the characteristics of low failure rate and high reliability.

[0030] Correspondingly, the pad printing mechanism described in this application can be installed on a suitable handicraft pad printer for application.

[0031] As described above, it should be noted that the number of teeth of the gear 8 and the driving rod 7 can be adjusted according to the actual situation, so that when the driving rod 7 moves horizontally once, it can drive the gear 8 to rotate one week, and the scraping knife 14 reciprocates back and forth once.

[0032] It should be noted that, in order to prevent possible physical interference between the rubber head 6 and the squeegee 14 during movement, the sizes, heights and specifications of the rubber head 6 and the squeegee 14 are adjusted according to the actual situation, which will not be elaborated here.

[0033] This specific embodiment is only an interpretation of the present invention, and it is not a limitation of the present invention. After reading this specification, those skilled in the art can make modifications to this embodiment without creative contributions as needed, but as long as it is within the scope of the claims of the present invention, it is protected by the Patent Law.
