[0002] A pad printing device is a printing equipment applicable to plastics, toys, glass, metal, ceramics, electronics, IC packaging, etc. Pad printing is an indirect concave rubber head printing technology and has become a main method for printing and decorating various object surfaces.

[0003] In a pad printing device, an oil cup is usually used to coat the ink on an etched plate and scrape off the excess ink. In order to make the seal between the oil cup and the etched plate better, a magnet is provided on the existing oil cup, and the magnet adsorbs on the etched plate.

[0004] The light-chasing printing effect of magnetic ink is a special printing effect. It utilizes the characteristics of magnetic ink and, through the action of an external magnetic field, makes the printed pattern or text present different colors or effects at different angles. This effect mainly depends on the directional arrangement of magnetic particles in the magnetic ink under the action of the magnetic field, thereby generating specific optical changes.

[0005] In order to make the printed substrate present a light-chasing effect of multiple colors, the current production method is to print multiple layers of magnetic ink of different colors on the substrate. Specifically, after applying or spraying a layer of magnetic ink of one color on the substrate, the substrate is moved to a cat's eye machine for magnetic positioning and curing, and then another layer of magnetic ink of another color is used to make the second layer of magnetic ink.

[0006] However, the existing manufacturing method wastes magnetic ink and has low efficiency. Summary of the Utility Model

[0038] The following describes a multi-color pad printing device with a light-chasing printing effect of magnetic ink according to an embodiment of the present utility model in conjunction with the accompanying drawings.

[0039] The present utility model aims to provide an embodiment of a multi-color pad printing device with a light-chasing printing effect of magnetic ink.

[0040] Refer to Figure 1 In this embodiment, a multi-color pad printing device with a light-chasing printing effect of magnetic ink mainly includes a frame 100, an inking mechanism 130, a pad printing mechanism 140, and a curing mechanism 150.

[0041] Refer to Figure 2 For the frame 100, a turntable 110 is rotatably arranged on the frame 100, and a plurality of carriers 120 are arranged on the turntable 110. The plurality of carriers 120 are arranged at equal intervals along the circumferential direction of the turntable 110. The carriers 120 are used for loading and positioning the printing substrates. Thus, when the turntable 110 rotates, it can drive the plurality of carriers 120 on the turntable 110 to move between various processes simultaneously, enabling each process on the pad printing device to be processed simultaneously, and further improving the processing efficiency of the pad printing device.

[0042] Specifically, a second motor is arranged on the frame 100, and the second motor is used to drive the turntable 110 to rotate.

[0043] In some specific embodiments, the number of carriers 120 is at least one more than the sum of the numbers of the pad printing mechanisms 140 and the curing mechanisms 150. Thus, when the pad printing mechanism 140 and the curing mechanism 150 are respectively printing and curing the substrates on the carriers 120 on the turntable 110, at least one carrier 120 is idle, so that workers can load and unload substrates on the idle carriers 120 when the pad printing mechanism 140 and the curing mechanism 150 are working, thereby eliminating the time of stopping to wait for loading and unloading, thereby improving the working efficiency of the pad printing device.

[0044] In some specific embodiments, the number of carriers 120 is two more than the sum of the numbers of the pad printing mechanism 140 and the curing mechanism 150. Thus, when the pad printing mechanism 140 and the curing mechanism 150 are respectively printing and curing the substrates on the carriers 120 on the turntable 110, two carriers 120 are idle, so that workers can load and unload the substrates on the two idle carriers 120 simultaneously when the pad printing mechanism 140 and the curing mechanism 150 are working, eliminating the time for stopping to wait for loading and unloading and further reducing the time for loading and unloading, thereby further improving the working efficiency of the pad printing device.

[0045] Reference Figure 1 and Figure 3 As for the ink spreading mechanism 130, at least two ink spreading mechanisms 130 are provided, and at least two ink spreading mechanisms 130 are arranged outside the turntable 110 along the circumference of the turntable 110. The ink spreading mechanism 130 is used to spread the magnetic ink, so that the pad printing device can provide at least two different colors of magnetic inks for printing on the substrate, and further, the pad printing device can print at least two colors of magnetic ink on the substrate, so as to realize multi-color printing with light tracking printing effect on the substrate and improve efficiency.

[0046] Reference Figure 4 In some specific embodiments, the ink spreading mechanism 130 includes a mounting seat 200, an etching plate 210 arranged on the mounting seat 200, an oil cup 220 slidably arranged on the etching plate 210, and a pressing plate 230 for pressing the oil cup 220 toward the etching plate 210. Two first magnetic strips 240 parallel to the moving direction of the oil cup 220 are arranged on the mounting seat 200. The two first magnetic strips 240 are respectively located on both sides of the etching plate 210. The first magnetic strips 240 are used to adsorb the pressing plate 230 so that the pressing plate 230 drives the oil cup 220 to press the etching plate 210.

[0047] It can be understood that by setting the first magnetic strip 240, the length direction of the first magnetic strip 240 is parallel to the moving direction of the oil cup 220. Thus, the first magnetic strip 240 can be continuously distributed along the path of the moving direction of the oil cup 220. Furthermore, the magnetic force of the first magnetic strip 240 is uniform and uninterrupted along the moving path of the oil cup 220, avoiding the situation that during the movement of the oil cup 220, the magnetic force of the first magnetic strip 240 is intermittent and non-uniform in the moving path of the oil cup 220, which may cause the movement of the oil cup 220 to be stuck. Additionally, by arranging two first magnetic strips 240 on both sides of the etching plate 210 respectively, the first magnetic strip 240 can be far away from the magnetic ink on the etching plate 210, preventing the first magnetic strip 240 from adsorbing and taking away the magnetic ink on the etching plate 210 when the oil cup 220 moves on the etching plate 210, ensuring the printing effect of the pad printing device using magnetic ink. Thus, the pad printing device can transfer the magnetic ink with a light-chasing printing effect to the printing substrate. Compared with the existing coating method with low efficiency and the spraying method with waste of magnetic ink, the pad printing device of the present utility model can improve efficiency and avoid waste of magnetic ink.

[0048] Referring to Figure 5 , further, a first magnetic component 250 is provided at the bottom of the pressing plate 230. The first magnetic component 250 and the first magnetic strip 240 adsorb each other. Thus, the suction force between the first magnetic component 250 and the first magnetic strip 240 is stronger. Furthermore, the pressure of the pressing plate 230 on the oil cup 220 is strengthened, making the sealing effect between the oil cup 220 and the etching plate 210 better, and reducing the risk of magnetic ink leakage between the oil cup 220 and the etching plate 210.

[0049] In some specific embodiments, the ink spreading mechanism 130 further includes a translation member and a first driving member for driving the translation member to translate. The translation member is slidably connected to the frame 100, and the translation member is connected to the pressing plate 230. The translation member translates to drive the pressing plate 230 to move.

[0050] Referring to Figure 1 and Figure 6 , for the pad printing mechanism 140, the pad printing mechanism 140 is correspondingly arranged with the ink spreading mechanism 130. The pad printing mechanism 140 is located between the ink spreading mechanism 130 and the turntable 110. The pad printing mechanism 140 is used to transfer the magnetic ink on the ink spreading mechanism 130 to the printing substrate on the carrier 120. Thus, the pad printing mechanism 140 can adhere and transfer the magnetic ink pre-spread according to the printing pattern to the printing substrate by the pad printing method. Furthermore, compared with the existing spraying method with waste of magnetic ink, the pad printing device of the present utility model can avoid waste of magnetic ink and save magnetic ink.

[0051] In some specific embodiments, the pad printing mechanism 140 includes a first translation frame 260 horizontally slidably connected to the frame 100, a first lifting frame 270 vertically slidably connected to the first translation frame 260, and a rubber head 280 disposed at the bottom of the first lifting frame 270. The rubber head 280 is used to adsorb the magnetic ink on the ink spreading mechanism 130 and print the magnetic ink on the printing substrate on the carrier 120. The first translation frame 260 and the first lifting frame 270 cooperate to drive the rubber head 280 to move back and forth between the ink spreading mechanism 130 and the carrier 120. Thus, it is convenient to transfer the magnetic ink spread on the ink spreading mechanism 130 to the printing substrate on the carrier 120, improving the printing efficiency.

[0052] Specifically, a third motor and a first screw rod are disposed on the frame 100. The first screw rod is rotatably arranged on the frame 100 and is threadedly connected to the first translation frame 260. The third motor is used to drive the first screw rod to rotate, and the rotation of the first screw rod drives the first translation frame 260 to translate.

[0053] Further, a first cylinder is disposed on the first translation frame 260, and the first cylinder drives the first lifting frame 270 to move up and down.

[0054] Referring to Figure 7 In some specific embodiments, the frame 100 is further provided with a cleaning assembly 290. The cleaning assembly 290 is located between the ink spreading mechanism 130 and the turntable 110. The cleaning assembly 290 includes a support plate 300, a tape unwinding roller 310 located at one end of the support plate 300, a tape winding roller 320 located at the other end of the support plate 300, and a first motor 330 for driving the tape winding roller 320 to wind. The tape unwinding roller 310 is used to support the unwinding of the tape roll, the tape winding roller 320 is used to support the winding of the tape roll, the support plate 300 is used to support the tape, and the rubber head 280 abuts against the tape on the support plate 300 so that the tape adheres to the residual magnetic ink on the rubber head 280.

[0055] It can be understood that after the rubber head 280 prints the magnetic ink onto the substrate, magnetic ink may remain on the rubber head 280, and the remaining magnetic ink will affect the effect of the next pad printing of the rubber head 280. By setting up a cleaning mechanism, after the rubber head 280 prints the magnetic ink onto the substrate and during the process of returning to the inking mechanism 130, the first lifting frame 270 and the first translation frame 260 cooperate to drive the rubber head 280 to abut against the tape on the support plate 300, so that the tape adheres to the remaining magnetic ink on the rubber head 280. Thus, it is convenient to clean the remaining magnetic ink on the rubber head 280. At the same time, the winding roller 320, the unwinding roller 310 and the first motor 330 cooperate to drive the tape to move, so that the tape on the support plate 300 that adheres to the remaining magnetic ink on the rubber head 280 can be wound by the winding roller 320 and a new section of tape can move from the unwinding roller 310 to the support plate 300. Thus, it is avoided that the tape adhering to the remaining magnetic ink repeatedly contacts the rubber head 280, resulting in the magnetic ink on the tape re-adhering to the rubber head 280.

[0056] Further, the support rod plate is fixed on the frame 100, and two mounting plates are respectively arranged at both ends of the support plate 300. The winding roller 320 and the unwinding roller 310 are respectively rotatably arranged on the two mounting plates.

[0057] Referring to Figure 1 and Figure 8 and, for the curing mechanism 150, the curing mechanism 150 is correspondingly arranged with the inking mechanism 130. The curing mechanism 150 is used for magnetic positioning and curing of the magnetic ink on the substrate. The inking mechanism 130 and the curing mechanism 150 are arranged alternately and equidistantly in sequence along the circumferential direction of the turntable 110. Thus, after each pad printing mechanism 140 transfers a certain color of magnetic ink on an inking mechanism 130 onto the substrate, the turntable 110 can drive the corresponding carrier 120 to move into the curing mechanism 150 for magnetic positioning and curing of the magnetic ink, so that the curing mechanism 150 can produce a light chasing printing effect on the magnetic ink on the substrate and accelerate the curing speed of the magnetic ink. Furthermore, the production efficiency of the pad printing device is improved.

[0058] In some specific embodiments, the curing mechanism 150 includes a light shield 160, an electromagnet 170, and a UV curing lamp 180. The light shield 160 has a first channel 190 that penetrates from left to right. The first channel 190 allows the carrier 120 to pass through. The electromagnet 170 and the UV curing lamp 180 are arranged in the first channel 190. The electromagnet 170 is used for magnetic positioning of the magnetic ink on the printing substrate, and the UV curing lamp 180 is used for irradiating and curing the magnetic ink on the printing substrate. Thus, the light shield 160 can block the light of the UV curing lamp 180, avoiding the UV curing lamp 180 from harming the operator when irradiating and curing the magnetic ink. In addition, by providing the first channel 190 that penetrates from left to right in the light shield 160, it is convenient for the carrier 120 to enter the light shield 160 from one end of the first channel 190 for magnetic positioning and curing of the magnetic ink and leave the light shield 160 from the other end of the first channel 190.

[0059] Specifically, the electromagnet 170 is fixed to the top wall of the first channel 190.

[0060] It can be understood that the electromagnet 170 is fixed to the top wall of the first channel 190, so that the electromagnet 170 is arranged above the printing substrate. The electromagnet 170 magnetically adsorbs the magnetic ink on the printing substrate for magnetic positioning of the magnetic ink. Thus, the electromagnet 170 can avoid the turntable 110 and the carrier 120, preventing the electromagnet 170 from interfering with the arrangement of the turntable 110 and the carrier 120.

[0061] Furthermore, there are two UV curing lamps 180, which are respectively arranged on both sides of the first channel 190. The height position of the UV curing lamp 180 is between the electromagnet 170 and the carrier 120, so that the light of the UV curing lamp 180 can irradiate the printing substrate through the gap between the printing substrate and the electromagnet 170. Thus, the irradiation and curing speed of the UV curing lamp 180 on the magnetic ink is increased, and the curing efficiency of the magnetic ink is improved.
