Description

Technical Field

[0001] The utility model relates to the technical field of pad printing equipment, in particular to a pad printing device with reflective printing effect of magnetic ink. Background Art

[0002] The reflective printing effect of magnetic ink is a special printing effect. It uses the characteristics of magnetic ink and the external magnetic field to make the printed pattern or text show different colors or effects at different angles. This effect mainly depends on the directional arrangement of magnetic particles in magnetic ink under the action of magnetic field, thus producing specific optical changes.

[0003] Pad printing machine is a kind of printing equipment, which is suitable for plastics, toys, glass, metal, ceramics, electronics, IC seals, etc. Pad printing is an indirect printing technology with a concave rubber head, and has become a major method for printing and decorating the surfaces of various objects.

[0004] In the related art, a pad printer usually uses an oil cup to apply ink on an etched plate and scrapes off excess ink during movement. In order to achieve a better seal between the oil cup and the etched plate, a magnet is provided on the existing oil cup, and the magnet is adsorbed on the etched plate.

[0005] Since magnetic ink contains metal, the magnet can easily absorb the magnetic ink when the ink cup moves on the etched plate, resulting in poor pad printing effect. Therefore, the current reflective printing effect of magnetic ink is generally produced by applying or spraying magnetic ink on the substrate and then moving the substrate to the cat's eye machine for magnetic positioning and curing.

[0006] However, existing methods for producing reflective printing effects with magnetic inks are inefficient and prone to waste magnetic inks. Utility Model Content

[0008] A pad printing device for the reflective printing effect of magnetic ink according to an embodiment of the present invention includes a frame, an ink spreading mechanism, a carrier, a pad printing mechanism, and a curing mechanism. The ink spreading mechanism is arranged on the frame and includes a fixed seat, an etching plate arranged on the fixed seat, an ink cup slidably arranged on the etching plate, and a pressing plate for pressing the ink cup towards the etching plate. Two magnetic adsorption components are arranged between the pressing plate and the fixed seat, and the two magnetic adsorption components are respectively located on both sides of the etching plate. The magnetic adsorption components are used to adsorb the pressing plate on the fixed seat; the carrier is used to support and position the printing substrate; the pad printing mechanism is arranged on the frame and includes a rubber head and a first moving component.

The second moving component is used to drive the carrier to move back and forth between the pad printing mechanism and the curing component.

The second moving component is used to drive the carrier to move back and forth between the pad printing mechanism and the curing component.

Thus, it eliminates the need for manual movement of the printing substrate to the curing mechanism, and further improves the efficiency.

[0036] The following describes a pad printing device for the reflective printing effect of magnetic ink according to an embodiment of the present utility model with reference to the accompanying drawings.

[0037] Refer to Figure 1 , the present utility model aims to provide an embodiment of a pad printing device for the reflective printing effect of magnetic ink.

[0038] In this embodiment, a pad printing device for the reflective printing effect of magnetic ink mainly includes a frame 100, an ink spreading mechanism, a carrier 160, a pad printing mechanism and a curing mechanism.

[0039] Refer to Figure 2 , Figure 3 and Figure 4 , for the ink spreading mechanism, the ink spreading mechanism is arranged on the frame 100. The ink spreading mechanism includes a fixed seat 110, an etched plate 120 arranged on the fixed seat 110, an ink cup 130 slidably arranged on the etched plate 120, and a pressing plate 140 pressing the ink cup 130 against the etched plate 120. There are two magnetic adsorption components 150 arranged between the pressing plate 140 and the fixed seat 110. The two magnetic adsorption components 150 are respectively located on both sides of the etched plate 120, and the magnetic adsorption components 150 are used to adsorb the pressing plate 140 on the fixed seat 110.

[0040] It can be understood that the two magnetic adsorption components 150 are respectively arranged on both sides of the etching plate 120, so that the magnetic adsorption components 150 will not contact and adsorb the etching plate 120, thereby enabling the magnetic adsorption components 150 to be far away from the magnetic ink on the etching plate 120, avoiding the magnetic adsorption components 150 from adsorbing and taking away the magnetic ink on the etching plate 120 when the ink cup 130 moves on the etching plate 120, ensuring the printing effect of the pad printing device using magnetic ink. Furthermore, the pad printing device can transfer the magnetic ink with a reflective printing effect onto the printing substrate. Compared with the low efficiency of the existing smearing method and the waste of magnetic ink in the spraying method, the pad printing device of the present utility model can improve efficiency and avoid wasting magnetic ink.

[0041] In some specific embodiments, the magnetic adsorption component 150 includes a first magnetic strip 210 and a first magnetic force member 220. The first magnetic strip 210 is arranged on the fixed seat 110, and the length direction of the first magnetic strip 210 is parallel to the moving direction of the ink cup 130. The first magnetic force member 220 is arranged at the bottom of the pressing plate 140. Thus, the first magnetic strip 210 can be continuously distributed in the path of the moving direction of the ink cup 130. Furthermore, the magnetic force of the magnetic strip is uniform and uninterrupted in the moving path of the ink cup 130, avoiding the magnetic force of the first magnetic strip 210 being intermittent and uneven in the moving path of the ink cup 130, which may cause the ink cup 130 to move stuck.

[0042] In some specific embodiments, the top surface of the first magnetic strip 210 is used to support the first magnetic force member 220, and the height of the top surface of the first magnetic strip 210 is 3 mm - 5 mm higher than the height of the top surface of the etching plate 120. Thus, the height distance between the first magnetic force member 220 and the etching plate 120 is increased, avoiding the first magnetic force member 220 from adsorbing the etching plate 120.

[0043] In some specific embodiments, the ink spreading mechanism further includes a first translation assembly 230, and the first translation assembly 230 is used to drive the pressing plate 140 to translate. Thus, the first translation assembly 230 can automatically drive the pressing plate 140 to translate so that the pressing plate 140 drives the ink cup 130 to translate on the etching plate 120. Furthermore, the efficiency is improved.

[0044] For the carrier 160, the carrier 160 is used to support and position the printing substrate. Thus, the printing substrate is more stable and accurate in position during printing. Furthermore, the printing accuracy is improved.

[0045] Refer to Figure 5, For the pad printing mechanism, the pad printing mechanism is arranged on the frame 100. The pad printing mechanism includes a rubber head 170 and a first moving component 180. The first moving component 180 is used to drive the rubber head 170 to reciprocate between the etching plate 120 and the carrier 160. The rubber head 170 is used to adsorb the magnetic ink on the etching plate 120 and print the magnetic ink on the printing substrate, thereby facilitating the transfer of the magnetic ink arranged on the etching plate 120 to the printing substrate on the carrier 160 and improving the printing efficiency.

[0046] In some specific embodiments, the first moving component 180 includes a first translation seat 240 slidably connected to the frame 100, a first screw rod 250 driving the first translation seat 240 to translate, a first motor 260 driving the first screw rod 250 to rotate, a lifting frame 270 slidably connected to the first translation seat 240 up and down, and a first air cylinder 280 driving the lifting frame 270 to lift. The rubber head 170 is installed at the bottom of the lifting frame 270.

[0047] It can be understood that the first motor 260 and the first screw rod 250 cooperate to drive the rubber head 170 to translate, so that the rubber head 170 can move back and forth between the upper part of the etching plate 120 and the upper part of the carrier 160 to transfer the magnetic ink. At the same time, it is convenient to control the pause position and pause time of the rubber head 170. In addition, the first air cylinder 280 drives the rubber head 170 to lift, so that the rubber head 170 can abut against the etching plate 120 to adhere to the magnetic ink and abut against the printing substrate to print the magnetic ink.

[0048] In some specific embodiments, a blower 290 is further arranged on the frame 100. The blower 290 is located between the fixed seat 110 and the carrier 160. The top of the blower 290 has an air outlet 300. The blower 290 is used to blow air on the magnetic ink at the bottom of the rubber head 170.

[0049] It can be understood that by arranging the blower 290 to blow air on the magnetic ink on the rubber head 170, it is convenient to control the dryness and humidity of the magnetic ink on the rubber head 170. Thus, the magnetic ink on the rubber head 170 is more likely to completely detach from the rubber head 170 and adhere to the printing substrate, making the printed pattern clearer.

[0050] Furthermore, in order to control the dryness and humidity of the magnetic ink on the rubber head 170, the rubber head 170 can be paused above the blower 290, and the pause time of the rubber head 170 above the blower 290 can be adjusted according to requirements.

[0051] Furthermore, hot air or cold air can be introduced into the blower 290 to adapt to the drying requirements of different magnetic inks.

[0052] Refer to Figure 6, for the curing mechanism, the curing mechanism is arranged on the frame 100. The curing mechanism includes a second moving component 190 and a curing component 200. The second moving component 190 is used to drive the carrier 160 to move back and forth between the pad printing mechanism and the curing component 200. The curing component 200 is used for magnetically positioning and curing the magnetic ink on the printing substrate.

[0053] It can be understood that after the magnetic ink is printed on the printing substrate on the carrier 160, the second moving component 190 can automatically drive the carrier 160 to move to the curing mechanism, so that the curing mechanism can complete the magnetic positioning and curing of the magnetic ink, making the cured magnetic ink have a reflective effect. Thus, it eliminates the need for manual movement of the printing substrate to the curing mechanism, and further improves the efficiency.

[0054] In some specific embodiments, the curing component 200 includes a light-shielding protective cover 310, an electromagnet 320, and a UV curing lamp 330. The electromagnet 320 and the UV curing lamp 330 are arranged inside the light-shielding protective cover 310. The electromagnet 320 is used for magnetically positioning the magnetic ink on the printing substrate, and the UV curing lamp 330 is used for irradiating and curing the magnetic ink on the printing substrate. One side of the light-shielding protective cover 310 has a first inlet and outlet 340, and the first inlet and outlet 340 facilitates the carrier 160 to enter the light-shielding protective cover 310. Thus, the light-shielding protective cover 310 can block the light of the UV curing lamp 330, avoiding the UV curing lamp 330 from hurting the operator when irradiating and curing the magnetic ink. In addition, by having the first inlet and outlet 340 on one side of the light-shielding protective cover 310, it is convenient for the carrier 160 to enter the light-shielding protective cover 310 from the first inlet and outlet 340 for magnetic positioning and curing of the magnetic ink.

[0055] In some specific embodiments, the electromagnet 320 is arranged on the inner wall of the top of the light-shielding protective cover 310, and the electromagnet 320 magnetically positions the magnetic ink on the printing substrate above the printing substrate. The UV curing lamp 330 is arranged on the inner side wall of the light-shielding protective cover 310, and the UV curing lamp 330 irradiates the magnetic ink on the printing substrate through the gap between the printing substrate and the electromagnet 320.

[0056] It can be understood that the electromagnet 320 is arranged above the printing substrate, and the electromagnet 320 magnetically positions the magnetic ink by magnetically adsorbing the magnetic ink on the printing substrate. Thus, the electromagnet 320 can avoid the guide rail 350 and prevent the electromagnet 320 from interfering with the setting of the guide rail 350. At the same time, the light of the UV curing lamp 330 can irradiate the printing substrate through the gap between the printing substrate and the electromagnet 320, thereby improving the irradiation and curing speed of the UV curing lamp 330 on the magnetic ink and improving the curing efficiency of the magnetic ink.

[0057] In some specific embodiments, the second moving component 190 includes a guide rail 350, a second translation seat 360, and a power component 370. The guide rail 350 is arranged on the frame 100. One end of the guide rail 350 is located below the pad printing mechanism, and the other end of the guide rail 350 passes through the first inlet / outlet 340 and extends into the light-shielding protective cover 310. The second translation seat 360 is slidably arranged on the guide rail 350, and the carrier 160 is arranged on the second translation seat 360. The power component 370 is used to drive the second translation seat 360 to move back and forth below the pad printing mechanism and within the light-shielding protective cover 310.

[0058] It can be understood that the power component 370 drives the second translation seat 360 to move on the guide rail 350, so that the second translation seat 360 can drive the carrier 160 to move back and forth below the pad printing mechanism and within the light-shielding protective cover 310. Thus, when the printing of the printed matter is completed in the printing area, the power component 370 can automatically drive the second to drive the printed matter to move into the light-shielding protective cover 310 for magnetic positioning and curing of the magnetic ink. Furthermore, the curing mechanism can automatically convey the printed printed matter and automatically complete magnetic positioning and curing, with simple operation and improved efficiency. In addition, when the magnetic positioning and curing of the magnetic ink on the printed matter are completed within the light-shielding protective cover 310, the power component 370 can automatically drive the second to drive the printed matter out of the light-shielding protective cover 310, facilitating blanking and replacing the next printed matter, thereby improving efficiency.

[0059] In some specific embodiments, two photoelectric sensors 380 are arranged on the guide rail 350. One photoelectric sensor 380 is located below the pad printing mechanism, and the other photoelectric sensor 380 is located within the light-shielding protective cover 310. The photoelectric sensors 380 are used to sense and position the second translation seat 360, so that the pause positions of the second translation seat 360 below the pad printing mechanism and within the light-shielding protective cover 310 are more accurate.
