Detailed Implementation

[0019] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0020] like Figure 1-5 As shown, a multi-color pad printing device includes a base 1, with at least two printing slots 2 arranged side-by-side on the upper surface of the base 1. It also includes a horizontal plate 3, with the same number of through slots as the printing slots 2 on the horizontal plate 3. An ink storage cavity 5 is disposed inside each through slot, and an annular and compressible sealing ring 6 is disposed at the lower end of the ink storage cavity 5. Two vertical rods 7 are disposed on the lower surface of the horizontal plate 3. A long groove for moving the vertical rods 7 is provided on the base 1, and a base plate 8 is disposed at the lower end of the two vertical rods 7. The device also includes a fixing plate 9, located between the base 1 and the base plate 8 and slidably connected to the vertical rods 7. Bolts 10 are also included, with one end rotatably connected to the fixing plate 9 and the bolts 10 threadedly connected to the horizontal plate 3. A moving assembly for moving the fixing plate 9 is disposed on the lower surface of the base 1. A mounting frame 11 is disposed on the upper surface of the horizontal plate 3, with the same number of pad printing components as the printing slots 2 disposed on the mounting frame 11. Each pad printing component includes components that slide against the mounting frame 11. The support column 12 is dynamically connected. The lower end of the support column 12 is provided with a pad printing head 13. The support column 12 is provided with a bottom ring 14 and a top plate 15. The bottom ring 14 and the top plate 15 are respectively located on both sides of the mounting frame 11. The support column 12 is also provided with a spring 16, which is sleeved on the support column 12 and is located between the mounting frame 11 and the top plate 15. The support plate 17 is also provided with a pressure plate 17, which is located above the pad printing head 13 and is slidably connected to the support column 12. The support column 1 is provided with a fixed seat 18 on one side. The fixed seat 18 is slidably connected with a movable plate 19. The movable plate 19 is provided with a vertical plate 20 on one side. The vertical plate 20 is provided with a handle 21 on one side. The vertical plate 20 is slidably connected with a positioning rod 22. One end of the positioning rod 22 is set as a hemispherical shape. The other end of the positioning rod 22 is provided with a side plate 23. An elastic block 24 is provided between the side plate 23 and the handle 21. The side of the fixed seat 18 has the same number of positioning slots 25 as the printing slot 2.

[0021] Before pad printing, each color ink is first added to each ink storage cavity 5. Then, the object to be pad printed is fixed to the fixture, and the fixture is fixed to the movable plate 19 by means of locking bolts, etc. At this time, the front end of the positioning rod 22 will enter the interior of the positioning groove 25 under the action of the elastic block 24. At this time, the position of the movable plate 19 is fixed, and the position of the fixture and the object on the fixture is also fixed, which facilitates accurate pad printing in the future.

[0022] The sealing ring 6 located at the bottom of the ink storage chamber 5 can prevent ink from seeping out from the bottom of the ink storage chamber 5. In order to improve the sealing performance between the sealing ring 6 and the upper surface of the base 1, the bolt 10 can be rotated. When the bolt 10 is rotated, it can drive the base plate 8 and the vertical rod 7 to move downward through the threaded connection between the bolt 10 and the base plate 8. When the vertical rod 7 moves downward, it will drive the horizontal plate 3 to move downward. When the horizontal plate 3 moves downward, it will drive the ink storage chamber 5 to move downward. When the ink storage chamber 5 moves downward, it will compress the sealing ring 6, thereby increasing the sealing performance between the sealing ring 6 and the upper surface of the base 1. In order to prevent the sealing ring 6 from being unable to move on the base 1, it is necessary to control the degree of compression of the sealing ring 6 so that the sealing ring 6 can both prevent ink from overflowing from the ink storage chamber 5 and allow the sealing ring 6 to move relatively freely on the upper surface of the base 1.

[0023] During pad printing, the fixed plate 9 is first moved by the moving component, which in turn moves the ink storage cavity 5 above it. The ink storage cavity 5 then moves to the position of the printing groove 2. Once in the printing groove 2, the ink in the ink storage cavity 5 can enter the printing groove 2. The moving component then controls the ink storage cavity 5 to reset. After resetting, the pad printing head 13 is directly above the printing groove 2. The pressure plate 17 is then moved downwards, simultaneously moving all the pad printing heads 13 downwards. During this downward movement, the ink in the printing groove 2 is transferred to the pad printing head 13. The moving component then pushes the ink storage cavity 5 back to the position of the printing groove 2, filling the printing groove 2 with ink. At this point, one of the pad printing heads 13 is directly above the object to be printed. The top plate 15 then presses against the column 12 where the pad printing head 13 is located. The pad printing head 13 is moved downwards, and the ink on the pad printing head 13 is transferred onto the object. After completing the single-color pad printing, the operator holds the handle 21 with one hand and hooks the side plate 23 with the fingers of that hand. Then, the side plate 23 is pulled to compress the elastic block 24 and move the positioning rod 22 out of the positioning groove 25. Then, the movable plate 19 is moved. After the positioning rod 22 moves away from the position of the positioning groove 25, the side plate 23 is released. Then, the movable plate 19 is moved. When it encounters the next positioning groove 25, the positioning rod 22 can quickly enter the positioning groove 25 under the action of the elastic block 24. At this time, the movable plate 19 can no longer move. At this time, the object to be printed is located directly below another pad printing head 13. Then, the pad printing head 13 is pushed downwards by the upright rod 34 and the top plate 15, thereby transferring the image on the pad printing head 13 onto the object, thus realizing two-color or even multi-color pad printing.

[0024] After the ink transfer of all colors of the object is completed, the ink storage chamber 5 is reset, and then the ink in the printing tank 2 is transferred to the printing head 13 to continue printing the next object.

[0025] The bottom ring 14 can keep the pad printing head 13 at a certain height, thereby reducing the distance that the pad printing head 13 moves downward each time.

[0026] Furthermore, the moving assembly includes two vertical plates 26 disposed on the lower surface of the base 1, and two guide rods 27 disposed between the two vertical plates 26. The guide rods 27 are slidably connected to the fixed plate 9. A lead screw 28 is disposed between the two vertical plates 26 and is threadedly connected to the fixed plate 9. A motor 29 for driving the lead screw 28 to rotate is disposed on the lower surface of the base 1. When controlling the movement of the ink storage cavity 5, the motor 29 is started, and the motor 29 drives the lead screw 28 to rotate. Through the threaded connection between the lead screw 28 and the fixed plate 9, and through the slidable connection between the guide rods 27 and the fixed plate 9, the fixed plate 9 can be moved, thereby moving the vertical rod 7, the horizontal plate 3, the ink storage cavity 5, and the sealing ring 6.

[0027] Furthermore, a cover plate 30 is rotatably connected to the upper surface of the horizontal plate 3, and a handle 31 is provided on the upper surface of the cover plate 30 to facilitate keeping the ink storage cavity 5 in a relatively closed state, so as to reduce the entry of impurities.

[0028] Furthermore, a handle 32 is provided on the upper surface of the top plate 15, which allows the user to hold the handle 32 and push the corresponding column 12 downward.

[0029] Furthermore, a fixing cylinder 33 is provided on the mounting frame 11, and the column 12 is slidably connected to the fixing cylinder 33 to improve the stability of the column 12 when it moves up and down.

[0030] Furthermore, the mounting frame 11 is provided with a vertical pole 34, and the pressure plate 17 is slidably connected to the vertical pole 34 to improve the stability of the pressure plate 17 when it moves up and down and reduce the possibility of the pressure plate 17 tilting.

[0031] Furthermore, handles 35 are provided at both ends of the pressure plate 17, which facilitates the downward movement of the pressure plate 17.
