The surface of the ink wheel 42 is provided with a scraping assembly 50, and the scraping assembly 50 includes a scraping plate 51 which is slidably connected to the surface of the ink wheel 42. When rotating, the scraping assembly 50 scrapes off the excess ink on the surface through the scraping plate 51, and the character groove with ink continues to rotate. The surface of the ink wheel 42 is connected to the transfer wheel 43 by rotation. The ink wheel 42 is located on one side of the transfer wheel 43, and the ink cartridge 41 is located below the ink wheel 42. The transfer wheel 43 is arranged on one side so that the ink cartridge 41 is above the rubber product, which can avoid blocking the ink cartridge. The surface of the transfer wheel 43 is provided with an elastic belt 44. When the inking wheel 42 contacts the transfer wheel 43, the ink in the shape of the characters in the character groove adheres to the transfer wheel 43, and is printed on the rubber product after the transfer wheel 43 contacts the rubber product. The elastic belt 44 made of elastic material can be deformed when in contact with the character mold, which is convenient for adhering ink. A wheel spacing adjustment component 60 is provided on one side of the support frame 40. The wheel spacing adjustment component 60 is used to adjust the contact pressure between the inking wheel 42 and the transfer wheel 43.

[0027] See also Figure 4 A second linkage shaft 70 is fixedly installed at the axis center of the transfer wheel 43, one end of the second linkage shaft 70 passes through the support frame 40 and is fixedly installed with a driving sprocket 71, the transfer wheel 43 rotates through the second linkage shaft 70 to drive the driving sprocket 71 to rotate, the other end of the first linkage shaft 64 passes through the support frame 40 and is fixedly installed with a linkage sprocket 72, the surfaces of the driving sprocket 71 and the linkage sprocket 72 are connected by a chain 73 for transmission, the diameter ratio between the driving sprocket 71 and the linkage sprocket 72 is the same as the diameter ratio between the transfer wheel 43 and the inking wheel 42, the driving sprocket 71 rotates through the chain 73 to drive the linkage sprocket 72 to rotate, the linkage sprocket 72 rotates through the first linkage shaft 64 to drive the inking wheel 42 to rotate, so that the inking wheel 42 and the transfer wheel 43 rotate synchronously, avoiding slipping during transfer, resulting in unclear fonts and excess ink stains affecting the appearance.

[0028] See also Figure 4 A regulating groove 74 is provided on one side of the support frame 40, and an regulating shaft 75 is installed inside the regulating groove 74. One end of the regulating shaft 75 is rotatably connected to an regulating gear 76. The regulating gear 76 is transmission-connected to the chain 73. When the chain 73 is installed, the chain 73 is meshed outside the regulating gear 76, and the position of the regulating shaft 75 inside the regulating groove 74 is adjusted. A nut is screwed on the surface of the regulating shaft 75, and the adjustment is completed after locking. The chain 73 can be set to a suitable tightness. The regulating shaft 75 whose position can be adjusted can also facilitate the disassembly and assembly of the chain, making it more convenient to use.

[0029] See also Figure 5The scraping assembly 50 also includes a support shaft 52 and an angle frame 53 fixedly installed with one end of the connected rod 66. A scraper frame 54 is rotatably arranged on the surface of the support shaft 52. The scraper frame 54 rotates with the support shaft 52. One side of the scraper plate 51 is fixedly installed with the scraper frame 54. A clamping stud 55 is threadedly connected to the top of the angle frame 53.

One end of the clamping spring 56 is fixedly installed with the scraper frame 54, so that the scraper frame 54 is close to the inking wheel 42. The pressure of the clamping spring 56 makes the scraper plate 51 always maintain a certain pressure when in contact with the inking wheel 42, so as to ensure the removal rate of ink on the surface of the inking wheel 42, so that the printing on the surface of the rubber product after printing by the printing device remains clean and tidy.

[0030] Beneficial effects:

[0031] 1. Driven by external power, the rubber product moves on the transmission shaft 11, and the rubber product contacts the transfer wheel 43, driving the transfer wheel 43 to rotate. The transfer wheel 43 drives the inking wheel 42 to rotate through the active sprocket 71, the chain 73 and the linkage sprocket 72. The inking wheel 42 rotates inside the ink cartridge 41 to adhere to the ink, and the ink enters the character groove on the surface of the inking wheel 42. When rotating, the excess ink scraping component 50 on the surface is scraped off by the scraping plate 51, and the character groove with ink continues to rotate. When the inking wheel 42 contacts the transfer wheel 43, the ink in the character shape in the character groove adheres to the transfer wheel 43. The transfer wheel 43 is on the rubber product after the transfer wheel 43 contacts the rubber product and prints on the rubber product. The device prints the transfer wheel 43 by rotating the inking wheel 42 in the ink cartridge 41. Since the inking wheel 42 is located on one side of the transfer wheel 43, the ink cartridge 41 can be set on one side of the transfer wheel 43, so that the ink cartridge 41 is above the rubber product, which can avoid blocking the ink cartridge, and can facilitate timely observation of ink consumption and replenishment of ink. The imprint of the rubber product is at the top, and the ink stain does not rub against other structures, so as to avoid rubbing the undried ink and make the printing clear.

[0032] 2. In a natural state, the linkage sleeve 63 is pulled to move under the restoring force of the tightening spring 65, so that the inking wheel 42 contacts the transfer wheel 43 with the tightest contact pressure, and the adjusting rod 68 is rotated. The adjusting rod 68 rotates and extends to push the connected rod 66 to rotate. The connected rod 66, the linkage sleeve 63 and the connecting rod 62 all rotate around the connecting rod shaft 61. The movement of the linkage sleeve 63 drives the inking wheel 42 to move, so that the contact pressure between the inking wheel 42 and the transfer wheel 43 can be adjusted, avoiding the problem of unclear fonts due to less ink adhesion or ink leakage caused by too little pressure on different sizes of character grooves during printing, so that a more appropriate amount of ink can be printed on rubber products during printing, and the drying time can be controlled.
