[0002] A pad printer is a printing device dedicated to pad printing technology. It is mainly used for printing on curved or irregularly shaped surfaces, such as toys, electronic product casings, ceramics and glass. The pad printer sprays ink on the printing template and then uses a silicone pad to transfer the pattern or text to the surface of the target object. Pad printer ink spraying is a common printing technology used to evenly spray ink on the printing template during the printing process.

[0003] The existing pad printing machine ink spraying is to spray ink on the printing template, and then use a scraper to scrape off the excess ink on the surface. Since some products need to be printed in multiple colors, each color is put into the corresponding ink box and then sprayed through the corresponding nozzle, the production cost is relatively high.

[0004] Therefore, it is necessary to design an ink spraying device for a pad printer that can quickly change inks of different colors for spraying, reduce production costs, and improve production flexibility. Utility Model Content

[0005] In order to overcome the disadvantage of existing pad printing machine ink spraying that some products need to be printed in multiple colors, each color is placed in a corresponding ink cartridge, and then ink is sprayed through a corresponding nozzle, resulting in high production cost. The utility model provides a pad printing machine ink spraying device that can quickly change inks of different colors for spraying, thereby reducing production costs and improving production flexibility.

[0006] An ink spraying device for a pad printer comprises a moving assembly, a mounting frame, a connecting plate, a feeding pipe and a hose. The moving assembly is connected to the mounting frame, a connecting plate is connected to the middle of the left side of the mounting frame, the feeding pipe is connected to the connecting plate, and the right side of the feeding pipe is connected to the hose.

[0007] To further explain, the moving assembly includes a rodless cylinder and a moving block. The rodless cylinder is provided with two front and rear ones. The rodless cylinder is connected to a moving block, and the moving blocks are connected to the mounting frame.

[0008] Further explanation: both the left and right parts of the rodless cylinder are provided with mounting seats.

[0009] Further description, it also includes a spraying part, the lower part of the hose is connected to the spraying part, and the spraying part is connected to the connecting plate.

[0010] Further description, it also includes a connecting block and a scraper, the left and right parts of the lower side of the connecting plate are connected to the connecting block, and the connecting block is connected to the scraper.

[0011] Further description, it also includes a connecting disk, a rotating rod, a rotating disk and a connecting nozzle. The feeding pipe is connected to the connecting disk, the left side of the connecting plate is rotatably connected to the rotating rod, the connecting disk is rotatably connected to the rotating disk, the rotating disk is connected to the rotating rod, and three connecting nozzles are evenly distributed on the left side of the rotating disk according to the circumference.

[0012] The beneficial effects are as follows: 1. The utility model drives the rotating disk to rotate on the connecting disk by rotating the rotating rod, so that the connecting nozzles connected to the ink material tubes of different colors are docked with the feeding tubes, and then the ink is sprayed through the spraying parts, thereby achieving the effect of being able to quickly change the inks of different colors for spraying, reducing production costs and improving production flexibility.

[0013] 2. The utility model moves the moving block left and right, and at this time the ink is sprayed on the printing template through the spraying part, and the ink flows into the groove on the printing template. At the same time, the scraper scrapes the ink on the surface. After the scraping is completed, the ink in the groove of the printing template is transferred to other products through the printing head, so that the ink jetting and scraping operations can be performed at the same time, saving time and improving the effect of ink printing efficiency.

DETAILED DESCRIPTION

[0018] The preferred technical solution of the present utility model is described in detail below with reference to the accompanying drawings.

[0019] An ink spraying device for a pad printer, such as Figure 1-Figure 3As shown, it includes a rodless cylinder 12, a moving block 13 and a mounting frame 1. The rodless cylinder 12 is provided with two front and rear parts, and the left and right parts of the rodless cylinder 12 are provided with mounting seats for easy installation and fixation. The rodless cylinder 12 is connected with a moving block 13, and the mounting frame 1 is connected between the moving blocks 13. It also includes a connecting plate 2, a feeding pipe 3 and a hose 4. The middle part of the left side of the mounting frame 1 is connected with a connecting plate 2, and the feeding pipe 3 is connected to the connecting plate 2. The right side of the feeding pipe 3 is connected to the hose 4. It also includes a spraying part 5, and the lower part of the hose 4 is connected with Spraying part 5, spraying part 5 is connected to connecting plate 2, and also includes connecting block 6 and scraper 7, both left and right parts of the lower side of connecting plate 2 are connected with connecting block 6, both connecting blocks 6 are connected with scraper 7, also includes connecting disk 8, rotating rod 9, rotating disk 10 and connecting nozzle 11, connecting disk 8 is connected to feeding pipe 3, rotating rod 9 is rotatably connected to the left side of connecting plate 2, rotating disk 10 is rotatably connected to the connecting disk 8, rotating disk 10 is connected to rotating rod 9, and three connecting nozzles 11 are evenly distributed on the left side of rotating disk 10 according to the circumference.

[0020] When using the device, firstly, the rodless cylinder 12 is installed in the ink spraying area of ​​the pad printer through the mounting seat, so that the scraper 7 contacts the printing template, and then the connecting nozzle 11 is docked with the material tube filled with ink, and then the rodless cylinder 12 is started, and the rodless cylinder 12 operates to drive the moving block 13 to move left and right.
