[0030] The pad printing machine is a common printing machine that can print on irregular object surfaces.

[0031] Chinese invention application CN118238508A discloses a pad printing machine that forms an ink taking station, a drying station, a cleaning station and a pad printing station respectively below four pad printing heads. The pad printing heads are respectively rotated to different stations to complete different processes.

[0032] But the above implementation still has defects. The working time of the pad printing head at the pad printing station is obviously longer than that of the pad printing head at other stations (because before pad printing, the pad printing head at the pad printing station needs to be precisely positioned, and in order to ensure the fineness of the pad printing pattern, the pad printing speed is also slower), so that the pad printing heads at other stations can only rotate to the next station after the pad printing head at the pad printing station completes the pad printing work. The pad printing heads at other stations do not effectively utilize the time waiting for the pad printing work, and because other stations, pad printing heads at other stations and corresponding components are set, and the components are distributed relatively scattered, the overall space occupied by the rotary pad printing mechanism is relatively large, and it is difficult to reduce the volume of the equipment under the premise of realizing the same function, ensuring the same pad printing quality and efficiency.

[0033] In order to solve the above problems, the present application provides a pad printing machine, which aims to make the overall space occupied by the pad printing machine smaller.

[0034] For the convenience of understanding, the specific embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0035] Please refer to Figure 1-3 A pad printing machine includes two pad printing heads 100, which can rotate according to a preset path, which can be circular, and the two pad printing heads 100 rotate relative to the center of the circle. A workbench 200 is formed with a pad printing station 300 and an ink taking station 400. The pad printing head 100 performs printing on the material at the pad printing station 300 and stains ink at the ink taking station 400. One pad printing head 100 is located at the pad printing station 300, and the other pad printing head 100 is located at the ink taking station 400. A cleaning assembly 500 and an ink supply assembly 600 are provided at the ink taking station 400. The cleaning assembly 500 includes a cleaning plate 510, and the ink supply assembly 600 includes an ink taking plate 610. The cleaning plate 510 and / or the ink taking plate 610 can be moved to below the pad printing head 100 located at the ink taking station 400. In this embodiment, how the cleaning plate 510 and / or the ink taking plate 610 are moved to below the pad printing head 100 located at the ink taking station 400 is not limited, and preferably, the cleaning plate 510 and / or the ink taking plate 610 can be moved through a sliding rail 800 and a sliding block 900. In this embodiment, how the pad printing head 100 is moved downward is not limited, and preferably, it can be driven by a motor 1000 or a hydraulic cylinder.

[0036] When the pad printing head 100 located on the ink taking station 400 needs to be cleaned and ink is taken, the cleaning plate 510 can be moved to the bottom of the pad printing head 100, the pad printing head 100 moves downward to contact the cleaning plate 510 to complete the cleaning, the pad printing head 100 moves upward to leave the cleaning plate 510, the cleaning plate 510 leaves the bottom of the pad printing head 100, the ink taking plate 610 moves to the bottom of the pad printing head 100, the pad printing head 100 moves downward to contact the ink taking plate 610 to complete the ink taking; or the cleaning plate 510 can be set under the pad printing head 100, the pad printing head 100 moves downward to contact the cleaning plate 510 to complete the ink taking. After cleaning is completed, the pad printing head 100 moves upward to leave the cleaning plate 510, the ink extraction plate 610 moves to the top of the cleaning plate 510, and the pad printing head 100 moves downward to contact the ink extraction plate 610 to complete ink extraction; alternatively, the ink extraction plate 610 may be disposed below the pad printing head 100, the cleaning plate 510 moves to the top of the ink extraction plate 610, the pad printing head 100 contacts the cleaning plate 510 downward to complete cleaning, the pad printing head 100 moves upward to leave the cleaning plate 510, the cleaning plate 510 leaves the top of the ink extraction plate 610, and then the pad printing head 100 moves downward to contact the ink extraction plate 610 to complete ink extraction. In other embodiments, the cleaning plate 510 and the ink extraction plate 610 may also contact the pad printing head 100 by moving upward, thereby enabling the pad printing head 100 to clean and extract ink, and the pad printing head 100 may also leave the cleaning plate 510 or the ink extraction plate 610 by moving horizontally.

[0037] In this embodiment, the time taken by the pad printing head 100 located on the pad printing station 300 to complete the pad printing work is longer than the time taken by the pad printing head 100 located on the ink collection station 400 to complete the ink collection and cleaning work. Compared with the implementation method of dividing the ink collection and cleaning into two stations, the implementation method of this embodiment effectively utilizes the characteristic that the pad printing head 100 on the pad printing station 300 takes a long time to complete the pad printing work, and merges the ink collection and cleaning work into one station to complete, which can reduce the number of pad printing heads 100 and stations, and effectively reduce the overall space occupied by the pad printing machine.

[0038] In order to ensure that the ink can be firmly attached to the surface of the product and achieve the expected printing effect,

[0039] The present invention also proposes another embodiment, see Figure 1-3 The ink taking station 400 is also provided with a drying component, which includes a drying member 700 for drying the pad printing head 100 located on the ink taking station 400 after taking ink.

Specifically, the cleaning plate 510 and the drying member 700 move together toward the top of the ink extraction plate 610. After the movement, the cleaning plate 510 is located above the ink extraction plate 610, and the drying member 700 is located next to the cleaning plate 510 so as not to hinder the cleaning of the pad printing head 100. The pad printing head 100 moves downward to contact the cleaning plate 510 to complete the cleaning. The pad printing head 100 moves upward to leave the cleaning plate 510, and then the cleaning plate 510 and the drying member 700 move in a direction away from the ink extraction plate 610 until the cleaning plate 510 and the drying member 700 are aligned. 00 is not located above the ink collection plate 610, the pad printing head 100 moves downward to contact the ink collection plate 610 to complete ink collection, the pad printing head 100 moves upward to leave the ink collection plate 610, and then the cleaning plate 510 and the drying component 700 move together to above the ink collection plate 610.

There are two options afterwards, one is that the drying component 700 moves to above the ink removal plate 610, and the pad printing head 100 moves downward to where the drying component 700 blows out hot air to complete drying, and the other is that the ink removal plate 610 leaves above the cleaning plate 510, the drying component 700 moves to above the cleaning plate 510, and the pad printing head 100 moves downward to where the drying component 700 blows out hot air to complete drying.

[0046] In another embodiment of the above, further, the drying member 700 may be arranged on one side of the ink collecting plate 610, or the ink collecting plate 610 may be arranged on one side of the drying member 700; the drying member 700 and the ink collecting plate 610 may move synchronously. Specifically, the pad printing head 100 moves downward to contact the cleaning plate 510 to complete cleaning, the pad printing head 100 moves upward to leave the cleaning plate 510, and then the drying component 700 and the ink removal plate 610 move together to above the cleaning plate 510. After the movement, the ink removal plate 610 is located above the cleaning plate 510, and the drying component 700 is located next to the ink removal plate 610 so as not to hinder the pad printing head 100 from removing ink. The pad printing head 100 moves downward to contact the ink removal plate 610 to complete ink removal, the pad printing head 100 moves upward to leave the ink removal plate 610, and then the ink removal plate 610 and the drying component 700 move together again so that the drying component 700 is located above the cleaning plate 510, and the ink removal plate 610 is located next to the drying component 700 so as not to hinder the pad printing head 100 from drying. The pad printing head 100 moves downward to where the drying component 700 blows out hot air to complete drying.

[0047] Method three: the drying member 700 is disposed below the pad printing head 100 located at the ink taking station 400 , and both the cleaning plate 510 and the ink taking plate 610 can be moved above the drying member 700 .

[0048] There are two options to choose from. One is that the cleaning plate 510 first moves to the top of the drying part 700, the pad printing head 100 moves downward to contact the cleaning plate 510 to complete cleaning, the pad printing head 100 moves upward to leave the cleaning plate 510, and then the ink removal plate 610 moves to the top of the cleaning plate 510, the pad printing head 100 moves downward to contact the ink removal plate 610 to complete ink removal, the pad printing head 100 moves upward to leave the ink removal plate 610, and then the cleaning plate 510 and the ink removal plate 610 both leave the top of the drying part 700, and the pad printing head 100 moves downward to where the drying part 700 blows out hot air to complete drying. Another method is that the cleaning plate 510 first moves to the top of the drying part 700, the pad printing head 100 moves downward to contact the cleaning plate 510 to complete cleaning, the pad printing head 100 moves upward to leave the cleaning plate 510, then the cleaning plate 510 leaves the top of the drying part 700, the ink removal plate 610 moves to the top of the drying part 700, the pad printing head 100 contacts the ink removal plate 610 downward to complete ink removal, the pad printing head 100 moves upward to leave the ink removal plate 610, the ink removal plate 610 leaves the top of the drying part 700, then the pad printing head 100 moves downward to the place where the drying part 700 blows out hot air to complete drying.

[0049] In another embodiment of the above, the cleaning plate 510 may be provided on one side of the ink extraction plate 610, or the ink extraction plate 610 may be provided on one side of the cleaning plate 510; the cleaning plate 510 and the ink extraction plate 610 may move synchronously. Specifically, the cleaning plate 510 and the ink extraction plate 610 move together toward the top of the drying member 700. After the movement, the cleaning plate 510 is located above the drying member 700, and the ink extraction plate 610 is located next to the cleaning plate 510 so as not to hinder the cleaning of the pad printing head 100. The pad printing head 100 moves downward to contact the cleaning plate 510 to complete the cleaning. The pad printing head 100 moves upward to leave the cleaning plate 510, and then the cleaning plate 510 and the ink extraction plate 610 move together again so that the ink extraction plate 610 is located above the drying member 700. Above, the cleaning plate 510 is located next to the ink collection plate 610 which does not hinder the pad printing head 100 from collecting ink. The pad printing head 100 moves downward to contact the ink collection plate 610 to complete the ink collection. The pad printing head 100 moves upward to leave the ink collection plate 610. Then the cleaning plate 510 and the ink collection plate 610 move together in the direction away from the drying part 700 until both the cleaning plate 510 and the ink collection plate 610 are no longer above the drying part 700. The pad printing head 100 moves downward to where the drying part 700 blows out hot air to complete the drying.

[0050] In this embodiment, the time taken by the pad printing head 100 located on the pad printing station 300 to complete the pad printing work is longer than the time taken by the pad printing head 100 located on the ink collection station 400 to complete the ink collection, cleaning and drying work. Compared with the implementation method of dividing the ink collection, cleaning and drying into three stations, the implementation method of this embodiment combines the ink collection, cleaning and drying work into one station by utilizing the characteristic that the pad printing head 100 on the pad printing station 300 takes a long time to complete the pad printing work, thereby reducing the number of pad printing heads 100 and stations, and effectively reducing the overall space occupied by the pad printing machine.

[0051] It should be noted that there are many ways to implement the drying unit 700. This embodiment provides the following implementations. Figure 4 The drying member 700 is provided with a groove 710, which is adapted to the pad printing head 100; a through hole for blowing out hot air is provided in the groove 710, so that the pad printing head 100 can be extended into the groove 710 for heating to obtain a uniform heating effect.
