[0025] Embodiment

[0026] As Figures 1-5 shown, a pad printing hot air device for a printing press includes a printing table 1. A housing 2 is movably connected to the outer surface of the printing table 1. A fan 3 is fixedly connected to the middle of the inner bottom wall of the housing 2. Air guide plates 4 are fixedly connected to both sides of the inner bottom wall of the housing 2. An electric heating pipe 5 is fixedly connected to the top of the inner side surface of the housing 2. An air outlet pipe 6 is fixedly connected to the upper surface of the housing 2. A control valve 7 is fixedly connected to the outer surface of the air outlet pipe 6. A hose 8 is inserted into the air outlet pipe 6. One end of the hose 8 is fixedly connected to a connector 9. A bending and shaping pipe 10 is fixedly connected to the outer surface of the connector 9. One end of the bending and shaping pipe 10 is fixedly connected to a spray head 11.

[0027] During specific use, through the settings of the fan 3, the electric heating pipe 5, the air outlet pipe 6, the hose 8, the bending and shaping pipe 10 and the spray head 11, multiple air outlet pipes 6 are evenly fixed on the upper surface of the housing 2 in a horizontal array form. The control valve 7 can be used to control the opening and closing state of the air outlet of the air outlet pipe 6. Different air outlet pipes 6 can be selected according to requirements. The hose 8 is inserted into the air outlet pipe 6. The connector 9 is fixed to the area to be dried through bolts. The hose 8 can adapt to the position change of the connector 9. The bending and shaping pipe 10 can be easily bent and maintain a fixed shape during use, so as to adapt to different installation environments and space limitations, and the adjustability is enhanced, enabling the spray head 11 to dry the product more accurately. The spray head 11 can expand the air outlet range of the pipeline, further improving the drying efficiency. When the fan 3 operates, external air is drawn into the housing 2. The air guide plates 4 guide the air flow, thereby expanding the wind force range. The electric heating pipe 5 heats the passing air. The heated air is conveyed through the air outlet pipe 6, the hose 8 and the bending and shaping pipe 10, and finally blows hot air to the designated area for drying under the action of the spray head 11. The number and installation positions of the hose 8 and the bending and shaping pipe 10 can be selected according to requirements. The device can not only dry the printed product, so that the ink on the pattern can be quickly dried, maintaining the integrity and clarity of the pattern, but also evenly heat the rubber head 30 of the pad printing mechanism, making the ink on the rubber head 30 solidify to a certain extent, so that the ink removal is more complete during printing and the ink layer thickness is more uniform, greatly improving the printing effect of the pattern.

[0028] In this embodiment, support seats 12 are movably connected to both sides of the outer surface of the housing 2. An installation plate 13 is fixedly connected to the outer surface of the support seat 12, and the installation plate 13 is fixedly connected to the printing table 1 by bolts.

[0029] During specific use, through the settings of the support seats 12 and the installation plate 13, the two support seats 12 support both sides of the housing 2, and then the installation plate 13 is fixed to the outer surface of the printing table 1 by bolts. The distance between the two support seats 12 can be adjusted according to the size of the housing 2, enhancing the applicability and making the installation and disassembly of the housing 2 more convenient.

[0030] In this embodiment, a through hole 14 is formed in the lower surface of the housing 2, and a clamping seat 15 is fixedly connected to one side of the lower surface of the housing 2 close to the through hole 14. A mesh plate 16 is clamped inside the clamping seat 15.

[0031] During specific use, through the setting of the mesh plate 16, the through hole 14 facilitates the intake of external air into the interior of the housing 2 when the fan 3 operates. The mesh plate 16 is clamped inside the clamping seat 15, with convenient installation and disassembly, facilitating cleaning and replacement after long-term use. When the fan 3 extracts air, large particulate impurities in the air can be filtered and blocked, which helps to reduce the situation where the rubber head 30 becomes dirty due to a large amount of dust in the air being blown onto the rubber head 30.

[0032] In this embodiment, a base 17 is fixedly connected to the middle of the inner bottom wall of the printing table 1. A first motor 18 is fixedly connected to the upper surface of the base 17. The output end of the first motor 18 is fixedly connected to a rotating rod 19, and one end of the rotating rod 19 is fixedly connected to a turntable 20.

[0033] During specific use, through the setting of the turntable 20, the base 17 is used to support and fix the first motor 18. The first motor 18 drives the rotating rod 19 to rotate, causing the turntable 20 to rotate, realizing the continuous conveyance of printed products and improving work efficiency.

[0034] In this embodiment, a fixing block 21 is fixedly connected to the edge of the upper surface of the turntable 20, and a T-shaped groove 22 is formed in the upper surface of the fixing block 21.

[0035] During specific use, through the setting of the T-shaped groove 22, multiple T-shaped grooves 22 are formed on the surface of the fixing block 21. Different jigs can be installed according to the shape of the product to clamp the workpiece to be printed, ensuring stability during printing.

[0036] In this embodiment, a support 23 is fixedly connected to the edge of the upper surface of the printing table 1, and a cross beam 24 is fixedly connected to the middle of the inner side surface of the support 23.

[0037] During specific use, through the setting of the support 23, the support 23 is used to support the pad printing mechanism, and the cross beam 24 strengthens the structural strength of the support 23, making it more firm and stable during use.

[0038] In this embodiment, a second motor 25 is fixedly connected to the middle of the outer surface of the cross beam 24. The output end of the second motor 25 is fixedly connected to a lead screw 26, and a slide plate 27 is threadedly connected to the outer surface of the lead screw 26.

[0039] During specific use, due to the arrangement of the lead screw 26, the second motor 25 drives the lead screw 26 to rotate, causing the slide plate 27 on its outer surface to move back and forth, thereby adjusting the front and back positions of the rubber head 30, facilitating the ink dipping and printing of the rubber head 30, and further improving the efficiency of pad printing.

[0040] In this embodiment, air cylinders 28 are fixedly connected to both sides of the upper surface of the slide plate 27. The output ends of the air cylinders 28 are fixedly connected to a support plate 29, and a rubber head 30 is fixedly connected to the lower surface of the support plate 29. An ink cup 31 is fixedly connected to one side of the upper surface of the printing table 1.

[0041] During specific use, due to the arrangement of the air cylinders 28, the support plate 29 is used to support the rubber head 30. The rubber head 30 and the ink cup 31 are used in cooperation to dip and print the ink. The output ends of the air cylinders 28 can be telescoped to control the height of the rubber head 30, thereby being applicable to the printing of products with different heights and improving the applicability of the device.

[0042] Working principle: During use, a fixture is installed inside the T-shaped groove 22 according to the shape of the printed matter, and then the printed matter is placed inside the fixture. The first motor 18 drives the rotating rod 19 to rotate, causing the turntable 20 to rotate, continuously conveying the printed matter. After printing, the printed product can also be taken out, and a new printed matter to be printed can be replaced. The output end of the air cylinder 28 extends to control the rubber head 30 to dip the ink through the ink cup 31, and then the rubber head 30 is reset. When the fan 3 operates, external air is drawn into the interior of the housing 2. The mesh plate 16 filters and blocks dust and impurities in the air. The air guide plate 4 guides the flow of air. The electric heating tube 5 heats the passing air. The heated air is conveyed through the air outlet pipe 6, the hose 8, and the bending and shaping tube 10, and finally, under the action of the nozzle 11, hot air is blown to a specified area for drying. One group of the hose 8 and the bending and shaping tube 10 allows the ink on the rubber head 30 to solidify to a certain extent faster through the nozzle 11, making the ink removal more complete during printing. Then, the second motor 25 drives the lead screw 26 to rotate, causing the slide plate 27 to move the rubber head 30 above the printed matter. The output end of the air cylinder 28 extends to make the rubber head 30 print. After printing, the rubber head 30 repeats the above operations. The turntable 20 moves the printed product, and the other group of the hose 8 and the bending and shaping tube 10 dries the printed product through the nozzle 11, enabling the ink on the pattern to be quickly dried.
