Description

Technical Field

[0001] This utility model belongs to the field of pad printing machine technology, and specifically relates to a pad printing machine for printing. Background Technology

[0002] Pad printing machines, as efficient and precise industrial printing equipment, are widely used in the manufacturing of electronic products, medical devices, and toys, and are especially suitable for printing graphics on curved, irregular, or non-standard surfaces. Their core principle involves a flexible silicone printing head that absorbs pre-designed ink patterns and then precisely transfers the ink to the surface of the target object. This technology, thanks to the high adaptability of the printing head and controllable pressure, enables high-resolution printing on complex surfaces, while also offering advantages such as flexible operation and high production efficiency.

[0003] During long-term continuous operation, the printing pads on pad printing machines are prone to accumulating residual paint on their surface due to repeated contact with ink and the substrate, resulting in uneven paint distribution on the pad surface. This problem directly affects the clarity and consistency of the printed pattern, especially in scenarios with fine patterns or high precision requirements, where it can easily lead to quality issues such as localized missing prints and blurred edges.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a pad printing machine for printing to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a pad printing machine for printing, including a pad printing machine body, a printing component is provided on the top of the inner wall of the pad printing machine body, a cleaning frame is fixedly connected to the bottom of the inner wall of the pad printing machine body, a movable wiping component is provided inside the cleaning frame, a squeezing component is provided on the outer side of the wiping end of the movable wiping component, and a rinsing component is provided inside the cleaning frame.

[0008] By moving the printing end of the printing component into the interior of the movable wiping component, the movable wiping component wipes the ink on the printing end of the printing component. The squeezing component is used to squeeze the wiping end of the movable wiping component so that the wiping end completely wraps around the printing end. The rinsing component is used to clean the ink adhering to the wiping end.

[0009] Furthermore, the printing assembly includes a position adjustment device, which is disposed on the top of the inner wall of the pad printing machine body. An installation block is fixedly installed on the adjustment end of the position adjustment device, a connecting rod is fixedly connected to the bottom of the installation block, and a printing pad is fixedly connected to the bottom end of the connecting rod.

[0010] Furthermore, the movable wiping assembly has a rotating roller, which is rotatably connected inside the cleaning frame. The outer surface of the rotating roller is provided with a moving belt, and the outer surface of the moving belt is provided with a plurality of socket grooves. Wiping cloths and wiping sponges are respectively fitted inside the plurality of socket grooves. The wiping sponges are provided on both sides of the wiping cloths. A drive motor is fixedly installed on the outside of the cleaning frame, and the output end of the drive motor is fixedly connected to the rotating roller.

[0011] Furthermore, the extrusion assembly includes a guide frame, which is fixedly connected to the outside of the cleaning frame. A movable frame is movably connected to the outer surface of the guide frame, and an L-shaped support plate is fixedly connected to one end of the movable frame. An extrusion roller is rotatably connected inside the L-shaped support plate.

[0012] Furthermore, a spring is fixedly connected between the cleaning frame and the movable frame, a push rod is fixedly connected to one side of the L-shaped support plate, a fixed rod is fixedly connected to the outer surface of the connecting rod, and push wedges are fixedly connected to both ends of the fixed rod corresponding to the push rod.

[0013] Furthermore, the rinsing assembly includes a rinsing box, which is fixedly installed on the inner wall of the cleaning frame. Several nozzles are fixedly connected to the front of the rinsing box, a transport pipe is fixedly connected to the outer side of the cleaning frame corresponding to the rinsing box, and a discharge pipe is fixedly connected to the outer side of the cleaning frame.

[0014] Furthermore, the cleaning frame is rotatably connected to several rotating shafts, and scraping plates are fixedly connected to the outer surfaces of the rotating shafts. A storage tube is fixedly connected to the outer side of the cleaning frame corresponding to the rotating shaft. The rotating shaft and the storage tube are rotatably connected, and a torsion spring is fixedly connected between the rotating shaft and the storage tube.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model moves the printing end of the printing component to the inside of the movable wiping component. At this time, the wiping end on the movable wiping component forms a dynamic wrap around the surface of the printing end under the pressure of the squeezing component. At the same time, by driving the movable wiping component, the wiping end is displaced along the contour of the printing end. The above setting, through the dual effect of wrap-around contact and dynamic friction, enables the movable wiping component to fully conform to the curved surface of the rubber head and efficiently remove residual ink, thereby significantly reducing defects such as printing blur and edge loss caused by ink residue, and achieving a two-way improvement in cleaning efficiency and printing quality.

[0017] 2. When the printing head is moved between the two sets of wiping sponges by the position adjustment device, the push wedge pushes the moving frame through the fixed rod, thereby causing the two sets of extrusion rollers to apply radial pressure to the wiping sponge, forcing the sponge to adaptively conform to the outer contour of the printing head to form a wrapping state; after cleaning, the printing head returns upward, pushing the wedge to disengage from the fixed rod, the spring drives the moving frame to reset, and the extrusion rollers release the compression on the sponge, allowing the sponge to return to its initial spacing; the above settings ensure that the printing head is not obstructed when moving between the two sets of wiping sponges, and that the two sets of wiping sponges can properly wrap the printing head.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0029] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0030] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0031] Please see Figures 1-7 As shown, this utility model is a pad printing machine for printing, including a pad printing machine body 1. A printing component 2 is provided on the top of the inner wall of the pad printing machine body 1. A cleaning frame 3 is fixedly connected to the bottom of the inner wall of the pad printing machine body 1. A movable wiping component 4 is provided inside the cleaning frame 3. A squeezing component 5 is provided on the outer side of the wiping end of the movable wiping component 4. A rinsing component 6 is provided inside the cleaning frame 3.

[0032] By moving the printing end of the printing component 2 into the interior of the movable wiping component 4, the movable wiping component 4 wipes the ink on the printing end of the printing component 2. The squeezing component 5 is used to squeeze the wiping end of the movable wiping component 4 so that the wiping end completely wraps around the printing end. The rinsing component 6 is used to clean the ink adhering to the wiping end.

[0033] After the printing component 2 has been working for a period of time, it is driven so that the printing end of the printing component 2 can move into the interior of the movable wiping component 4. At this time, the squeezing component 5 can squeeze the movable wiping component 4, so that the movable wiping component 4 can wrap the printing end. At the same time, the wiping end of the movable wiping component 4 moves to wipe the residual ink on the surface of the printing end. When the wiping end moves into the interior of the cleaning frame 3, the rinsing component 6 rinses the ink adhering to the wiping end.

[0034] By moving the printing end of the printing component 2 into the interior of the movable wiping component 4, the wiping end on the movable wiping component 4 can wrap around the printing end under the pressure of the squeezing component 5. At the same time, the wiping end moves continuously, thereby wiping away the residual ink on the printing end. In the above setting, since the wiping end can wrap around the printing end and can move continuously, the residual ink on the printing end can be better cleaned. At the same time, it avoids quality problems such as partial missing printing and blurred edges caused by residual ink on the printing end during pattern printing.

[0035] In one embodiment, the printing component 2 includes a position adjustment device 201, which is disposed on the top of the inner wall of the pad printing machine body 1. An installation block 202 is fixedly installed on the adjustment end of the position adjustment device 201, and a connecting rod 203 is fixedly connected to the bottom of the installation block 202. A printing pad 204 is fixedly connected to the bottom end of the connecting rod 203.

[0036] The position adjustment device 201 can move horizontally and vertically. This is existing technology and will not be described in detail here. The position adjustment device 201 drives the mounting block 202, so that the mounting block 202 drives the printing head 204 to adjust its position through the connecting rod 203. This allows the printing head to automatically adjust its position between the pattern ink, the cleaning frame 3 and the target object.

[0037] In one embodiment, for the aforementioned movable wiping assembly 4, the movable wiping assembly 4 has a rotating roller 401, which is rotatably connected inside the cleaning frame 3. The outer surface of the rotating roller 401 is provided with a moving belt 402, and the outer surface of the moving belt 402 is provided with a plurality of fitting grooves 403. Wiping cloths 404 and wiping sponges 405 are respectively fitted inside the plurality of fitting grooves 403. The wiping sponges 405 are provided on both sides of the wiping cloths 404. A drive motor 406 is fixedly installed on the outer side of the cleaning frame 3, and the output end of the drive motor 406 is fixedly connected to the rotating roller 401.

[0038] By driving the position adjustment device 201, the printing head 204 can be moved to the top of the cleaning frame 3, while the bottom of the printing head 204 contacts the wiping cloth 404, and the wiping sponge 405 contacts the outer surface of the printing head 204. At this time, the drive motor 406 drives the rotating roller 401, which in turn drives the moving belt 402 to move. Under the movement of the moving belt 402, the wiping cloth 404 and the wiping sponge 405 can move along the printing head 204. The outer side of the 404 moves to wipe the ink remaining on the printing head 204. Since the wiping cloth 404 and the wiping sponge 405 are movable, they wipe the ink remaining on the printing head 204, which makes the cleaning effect of wiping the ink better. At the same time, the inside of the wiping cloth 404 and the wiping sponge 405 can be provided with elastic bands, which can be used to fit the two into the corresponding socket 403. This setting makes it convenient to replace the wiping cloth 404 and the wiping sponge 405.

[0039] In one embodiment, the extrusion assembly 5 includes a guide frame 501, which is fixedly connected to the outside of the cleaning frame 3. A movable frame 502 is movably connected to the outer surface of the guide frame 501. An L-shaped support plate 503 is fixedly connected to one end of the movable frame 502. An extrusion roller 504 is rotatably connected inside the L-shaped support plate 503.

[0040] After the printing head 204 moves between the wiping cloth 404 and the wiping sponge 405, the moving frame 502 is moved, causing the moving frame 502 to move along with the L-shaped support plate 503 and the squeezing roller 504 under the drive of the guide frame 501. This allows the squeezing roller 504 to squeeze the wiping sponge 405. Since there are two squeezing rollers 504 on each side of the cleaning frame 3, the wiping sponge 405 can fully contact the outer surface of the printing head 204 under the squeezing of the squeezing rollers 504, thus ensuring the effectiveness of cleaning residual ink. At the same time, since the squeezing roller 504 is rotatably connected to the L-shaped support plate 503, the wiping sponge 405 will not be unable to move due to the squeezing force generated by the squeezing roller 504.

[0041] In one embodiment, for the cleaning frame 3, a spring 505 is fixedly connected between the cleaning frame 3 and the movable frame 502, a push rod 506 is fixedly connected to one side of the L-shaped support plate 503, a fixing rod 507 is fixedly connected to the outer surface of the connecting rod 203, and push wedges 508 are fixedly connected to both ends of the fixing rod 507 corresponding to the push rod 506.

[0042] When the printing head 204 moves between the two wiping sponges 405 under the drive of the position adjustment device 201, the two pushing wedges 508 on the fixing rod 507 come into contact with the fixing rod 507. At this time, the printing head 204 continues to move downward, and at the same time, the fixing rod 507 pushes the moving frame 502 under the squeezing of the pushing wedges 508, so that the two squeezing rollers 504 can squeeze the wiping sponge 405. When the bottom of the printing head 204 comes into contact with the wiping cloth 404, the wiping sponge 405 also completes the wiping of the surface of the printing head 204 under the squeezing of the squeezing rollers 504. The printing head 204 is wrapped with ink. After the ink residue on the printing head 204 is cleaned, as the printing head 204 moves upward, the pushing wedge 508 continuously disengages from the fixed rod 507. At this time, the spring 505 can push the moving frame 502 outward, so that the moving frame 502 can drive the squeezing roller 504 to continuously reset, and at the same time, the squeezing roller 504 no longer squeezes the wiping sponge 405. The above settings allow the printing head 204 to move normally between the two wiping sponges 405, and the two wiping sponges 405 can automatically wrap the printing head 204.

[0043] In one embodiment, the rinsing assembly 6 includes a rinsing box 601, which is fixedly installed on the inner wall of the cleaning frame 3. A plurality of nozzles 602 are fixedly connected to the front of the rinsing box 601. A transport pipe 603 is fixedly connected to the outer side of the cleaning frame 3 corresponding to the rinsing box 601, and a discharge pipe 604 is fixedly connected to the outer side of the cleaning frame 3.

[0044] The transport pipe 603 is connected to the outer cleaning fluid storage container. After the wiping cloth 404 and wiping sponge 405 have finished wiping and are moved into the cleaning frame 3 by the moving belt 402, the cleaning fluid inside the storage container flows into the rinsing box 601 through the transport pipe 603. At this time, the nozzle 602 can spray the cleaning fluid inside the rinsing box 601 onto the continuously moving wiping cloth 404 and wiping sponge 405, so that the ink adhering to the wiping cloth 404 and wiping sponge 405 can be washed away. The wastewater generated during the cleaning process can flow out from the inside of the cleaning frame 3 through the discharge pipe 604. The above configuration ensures that when the wiping cloth 404 and wiping sponge 405 wipe the printing head 204 again, the surfaces of both can remain clean, thus ensuring the cleaning effect.

[0045] In one embodiment, for the cleaning frame 3, a plurality of rotating shafts 605 are rotatably connected inside the cleaning frame 3, and scraping plates 606 are fixedly connected to the outer surfaces of the plurality of rotating shafts 605. A storage tube 607 is fixedly connected to the outer side of the cleaning frame 3 corresponding to the rotating shafts 605. The rotating shafts 605 and the storage tube 607 are rotatably connected, and a torsion spring 608 is fixedly connected between the rotating shafts 605 and the storage tube 607.

[0046] The torsion spring 608 can drive the scraper 606 to rotate upward via the rotating shaft 605, so that the scraper 606 can tilt and squeeze the corresponding wiping cloth 404 and wiping sponge 405. Under the squeezing of the scraper 606, the cleaning fluid and ink waste inside the wiping cloth 404 and wiping sponge 405 can fall directly into the cleaning frame 3. This setting makes the wiping cloth 404 and wiping sponge 405 wipe the printing head 204 again, and the rinsing effect when wiping the printing head 204 is better. At the same time, the two can keep relatively dry, effectively preventing the cleaning fluid from adhering to the surface of the printing head 204.

[0047] Through the above technical solution, 1. By moving the printing end of the printing component 2 into the interior of the movable wiping component 4, the wiping end on the movable wiping component 4 forms a dynamic wrap around the surface of the printing end under the pressure of the squeezing component 5. At the same time, by driving the movable wiping component 4, the wiping end is displaced along the contour of the printing end. The above setting, through the dual action of wrap-around contact and dynamic friction, enables the movable wiping component 4 to fully conform to the curved surface of the printing head and efficiently remove residual ink, thereby significantly reducing defects such as printing blurring and edge loss caused by ink residue, and achieving a two-way improvement in cleaning efficiency and printing quality; 2. The printing head 204 is moved to the position adjustment device 201. When the two sets of wiping sponges 405 are in contact, the pushing wedge 508 pushes the moving frame 502 through the fixing rod 507, thereby causing the two sets of squeezing rollers 504 to apply radial pressure to the wiping sponge, forcing the sponge to adaptively conform to the outer contour of the printing head to form a wrapping state; after cleaning, the printing head returns upward, pushing the wedge 508 to disengage from the fixing rod 507, the spring 505 drives the moving frame 502 to reset, and causes the squeezing rollers 504 to release the compression of the sponge, so that the sponge returns to the initial spacing; the above settings ensure that the printing printing head 204 is not obstructed when moving between the two sets of wiping sponges 405, and the two sets of wiping sponges 405 can normally complete the wrapping of the printing printing head 204.
