Description

Technical Field

[0001] The present invention relates to the technical field of printing machines, in particular to a UV special printing machine. Background Art

[0002] A printing press is a mechanical device that presses the inked surface against the media surface to form an image. Its working principle is: first, the text and image to be printed are made into a printing plate and installed on the printing press. Then, ink is applied to the areas with text and images on the printing plate by humans or the printing press, and then directly or indirectly transferred to paper or other printing materials, thereby reproducing a printed product identical to the printing plate. The invention and development of the printing press has played an important role in the dissemination of human civilization and culture, and UV printing press is also a type of printing press.

[0003] The core of a UV printer is the nozzle. The ink used in UV printers is generally quick-drying and pigment-based. The ink and pigment are easily precipitated, causing the nozzle to become clogged. When the nozzle is clogged with pigment and ink, ultrasonic cleaning can be used to clean the nozzle. However, the nozzle needs to be removed from the UV printer and then placed in an ultrasonic cleaning machine for cleaning. Regarding the above technical solution, the inventors found that the nozzle disassembly process is cumbersome, which makes it inconvenient to clean the nozzle when the nozzle is clogged.

[0004] To address the above shortcomings, China's authorized invention publication number: CN216761222U discloses a UV printer. The UV printer is provided with a cleaning box and a lifting mechanism. The lifting mechanism drives the cleaning box to move up and down. When the nozzle is clogged, the driving device drives the printing nozzle to the position of the cleaning box. The cleaning box can be raised by the lifting mechanism to clean the printing nozzle. Therefore, there is no need to disassemble the printing nozzle for cleaning, which is convenient to operate and easy to clean.

[0005] However, the structural design of the above-mentioned prior art does not have the function of wiping the moisture off the printing nozzle after cleaning. Residual moisture will remain in the printing nozzle. If the residual moisture cannot be removed in time, the printing efficiency of the UV printer will be affected.

[0031] The water absorption mechanism 10 is provided on the second circular gear 94 and includes an inclined plate 105 and a water-absorbing sponge 106 for absorbing water;

[0032] The cleaning mechanism 8 is arranged on the water absorption device control mechanism 9. The cleaning mechanism 8 includes a movable plate 83 threadedly connected to the outer surface of the threaded rod 92, and a cleaning box 81 fixed on the movable plate 83. An ultrasonic generator 82 is arranged on the front side of the cleaning box 81.

[0033] The water absorption mechanism 10 also includes an elastic member 101, the top of the elastic member 101 is rotatably connected to the bottom of the connecting plate 102, the bottom of the elastic member 101 is rotatably connected to the top of the second circular gear 94, and a short rod 12 is fixed to the bottom of the second circular gear 94. The bottom of the short rod 12 is connected to the inner bottom wall of the connecting hole 14 through a rotating device. For example, the bottom of the short rod 12 is connected to the inner bottom wall of the connecting hole 14 through a bearing, which limits the short rod 12 while allowing the short rod 12 to rotate. The elastic member 101 is stretched.

[0034] The water absorption mechanism 10 further includes a long plate 103 , one side of which is fixed to one side of the connecting plate 102 . A baffle 11 is fixed to the top left end of the bottom plate 7 , and a connecting hole 14 is provided at the front end of the upper left side of the baffle 11 .

[0035] The water absorption mechanism 10 also includes a connecting frame 104, and a water-absorbing sponge 106 is arranged inside the connecting frame 104. The top of the water-absorbing sponge 106 is higher than the top of the connecting frame 104, and the top of the connecting frame 104 is slightly higher than the bottom of the printing nozzle 6, so that the elastic member 101 generates elastic force when the bottom of the printing nozzle 6 contacts the water-absorbing sponge 106, so that the water-absorbing sponge 106 contacts the bottom of the printing nozzle 6 more closely.

[0036] The cleaning mechanism 8 includes a drain pipe 84 fixed to the bottom of the cleaning box 81, and a valve is provided in the middle of the drain pipe 84. The top of the drain pipe 84 is connected to the interior of the cleaning box 81. There is a gap between the lower part of the printing head 6 and the slide rail 3 that allows the rear wall thickness of the cleaning box 81 to pass through, allowing the printing head 6 to enter the interior of the cleaning box 81.

[0037] The inclined plate 105 is fixed to the rear side of the connecting frame 104, and the top of the connecting frame 104 is flush with the top of the inclined plate 105. The side of the connecting plate 102 close to the connecting plate 102 is set in an arc surface. When the inclined plate 105 contacts the printing nozzle 6, the inclined plate 105 will drive the connecting plate 102 to move downward.

[0038] A limit rod is fixed to the left end of the top of the bottom plate 7, and the outer surface of the limit rod is slidably connected to the middle of the movable plate 83. A collection box 13 is placed on the top of the bottom plate 7. The collection box 13 is located directly below the valve and is used to collect waste liquid discharged from the cleaning box.

[0039] It also includes a slide rail 3 and a screw rod 5 arranged inside the slide rail 3. A first motor 4 that drives the screw rod 5 to rotate is fixed to the right side of the slide rail 3. The outer surface of the screw rod 5 is connected to the printing nozzle 6 through a sliding block. The screw rod 5 and the sliding block are threadedly connected, and the rear side of the sliding block is slidably connected to the rear inner wall of the slide rail 3, which can limit the movement of the printing nozzle 6.

[0040] The working principle of this embodiment is as follows: when cleaning the print head 6 in the printing press, the first motor 4 is started, which drives the screw 5 to rotate, and the print head 6 moves to the top of the cleaning box 81. After that, the first motor 4 is stopped, and then the second motor 91 is started, which drives the threaded rod 92 to rotate. The threaded rod 92 drives the cleaning box 81 to move upward. At the same time, the threaded rod 92 drives the first circular gear 93 to rotate, and the first circular gear 93 drives the second circular gear 94 to rotate, thereby driving the water absorption mechanism 10 on the second circular gear 94 to rotate clockwise. When the print head 6 enters the interior of the cleaning box 81, the water absorption sponge 106 rotates into the connecting hole 14. Then, the ultrasonic generator 82 is started to clean the print head 6. After the cleaning is completed, the second motor 91 is reversed, thereby driving the water absorption mechanism 10 to move counterclockwise, so that the water absorption sponge 106 moves to the bottom of the print head 6 to absorb the residual water in the print head 6. The above is the working process of the entire device, and the content not described in detail in this specification belongs to the prior art known to professionals in this field.
