Technical Field

[0001] The present invention relates to the technical field of printer nozzle cleaning, and particularly to a cleaning device for multiple nozzles of a digital inkjet printer. Background Art

[0002] During the use of a digital inkjet printer, ink is ejected from the nozzles of the print head under the control of an inkjet controller at a certain pressure and then printed on the substrate. However, affected by factors such as air bubbles, dust in the ink, and ink solidified on the nozzle surface, the nozzles are prone to clogging, which will seriously affect the printing quality of the inkjet printer. Therefore, it is necessary to clean the print head regularly.

[0003] The patent with the patent announcement number CN219312330U relates to the technical field of printer nozzle cleaning. This application discloses an inkjet printer nozzle cleaning system, which includes a cleaning joint and a liquid storage tank. One end of the cleaning joint is communicated with the liquid storage tank, and the other end of the cleaning joint is communicated with the print head. The liquid storage tank is used to store the cleaning liquid. This application has the effect of flushing the ink in the print head and on the printing surface of the print head, ensuring the cleanliness of the print head.

[0004] In the above patent, there is an effect of flushing the ink in the print head and on the printing surface of the print head to ensure the cleanliness of the print head. However, the current equipment has the following problems: When the flushing pressure is too high, it may damage the precise structure inside the print head, and if the print head is already clogged, direct flushing with water may not effectively remove the blockage. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a cleaning device for multiple nozzles of a digital inkjet printer, which solves the problems raised in the above background art.

[0006] To achieve the above objectives, the present invention is realized through the following technical solutions: A cleaning device for multiple nozzles of a digital inkjet printer, including a bottom plate and a print head for cleaning the print head, comprising: A sliding rod frame, which is fixedly installed on the top of the bottom plate; A fixing ring, which is fixedly installed on the circumferential surface of the sliding rod frame; An arc block, which is fixedly installed on the inner wall of the fixing ring; An eccentric circle, which is rotatably installed on the surface of the bottom plate; A driving sleeve, which is fixedly installed on the left side of the eccentric circle; A pulley ring, which is fixedly installed on the circumferential surface of the driving sleeve. The pulley ring is used to generate vibrations when it comes into contact with the arc block; Placement plate, the placement plate is fixedly installed on the left side of the drive sleeve. After the bottom of the nozzle is in contact with the immersion liquid, the eccentric circle is rotated by the motor. The rotation of the eccentric circle causes the drive sleeve to rotate, and the rotation of the drive sleeve drives the placement plate to rotate. The rotation of the placement plate makes the nozzle perform eccentric circular motion; Threaded rod, the threaded rod is rotatably installed on the top of the placement plate; Clamping piece, the clamping piece is threadedly installed on the circumferential surface of the threaded rod; Elastic telescopic rod, the fixed end of the elastic telescopic rod is slidably installed on the surface of the slide bar frame, and the movable end of the elastic telescopic rod is fixedly installed on the top of the placement plate; the elastic telescopic rod is used to make the device adapt to the rotation of the eccentric circle.

[0007] According to the above technical solution, the pulley ring contacts the arc block. When the drive sleeve rotates, it drives the pulley ring to rotate. The rotation of the pulley ring will contact the arc block, causing the drive sleeve to vibrate; Among them, an immersion device for immersing the nozzle and a wiping device for cleaning are provided on the bottom plate; According to the above technical solution, the immersion device includes an immersion box, a pressing rod and an ink-absorbing cloth. The immersion box is slidably installed on the circumferential surface of the slide bar frame. The pressing rod is slidably installed on the inner wall of the immersion box. A first spring is provided between the pressing rod and the immersion box. The first spring is used to drive the pressing rod to reset. The ink-absorbing cloth is arranged on the surface of the pressing rod. A docking groove is opened on the outer wall of the immersion box. When the nozzle is immersed, the immersion box moves upward to contact the inclined surface of the plug, causing the plug to move to the right and compress the second spring at the same time. When the docking groove overlaps with the plug, the second spring resets to drive the plug to insert into the docking groove, and at this time the position of the immersion box is fixed.

[0008] According to the above technical solution, the immersion device further includes a stirring rod and a sliding plate. The stirring rod is rotatably installed on the inner wall of the immersion box. A reciprocating spiral groove is opened on the circumferential surface of the stirring rod. The sliding plate is threadedly installed on the circumferential surface of the stirring rod. The motor drives the stirring rod to rotate, so that the medicament is mixed. While the stirring rod rotates, the sliding plate performs left-right reciprocating movement through the opened reciprocating spiral groove.

[0009] According to the above technical solution, the soaking device further includes a chemical agent tank, a hollow block, a telescopic pipe, and a plug. The chemical agent tank is fixedly installed on the surface of the slide rod frame. The hollow block is fixedly installed at the bottom of the chemical agent tank. One side of the telescopic pipe is fixedly installed at the bottom of the chemical agent tank, and the other side of the telescopic pipe is fixedly installed on the inner wall of the soaking box. When the plug moves, it drives the Y-shaped rod to move, and when the Y-shaped rod moves, it drives the sealing plug to move, so that the chemical agent in the chemical agent tank enters the telescopic pipe and then enters the soaking box. The plug is slidably installed on the inner wall of the hollow block. The bottom of the plug is provided with an inclined surface. A second spring is arranged between the plug and the hollow block. The second spring drives the plug to fix and disassemble the soaking box.

[0010] According to the above technical solution, the soaking device further includes a Y-shaped rod and a sealing plug. The Y-shaped rod is fixedly installed at the top of the plug. One side of the sealing plug is slidably installed on the inner wall of the telescopic pipe, and the other side of the sealing plug is fixedly installed on the surface of the Y-shaped rod close to the soaking box. When the Y-shaped rod moves, it drives the sealing plug to move.

[0011] According to the above technical solution, the wiping device includes a moving pulley frame, a slide rail frame, and an electric push rod. The moving pulley frame is arranged on the top of the bottom plate. The slide rail frame is fixedly installed on the top of the bottom plate. The fixed end of the electric push rod is slidably installed on the circumferential surface of the slide rail frame. The moving pulley frame enables the fixed end of the electric push rod to move forward along the slide rail frame.

[0012] According to the above technical solution, the wiping device further includes a rope and a wiping cotton. One side of the rope is arranged at the fixed end of the electric push rod, and the other side of the rope is arranged at the rear side of the soaking box. The rope contacts the moving pulley frame. The wiping cotton is fixedly installed at the output end of the electric push rod. The output end of the electric push rod drives the wiping cotton to move back and forth to wipe the nozzle.

[0013] The present invention provides a cleaning device for multiple nozzles of a digital inkjet printer. It has the following beneficial effects: (1) In this invention, through the setting of the cleaning device, by clamping the nozzle after disassembling it, the position of the nozzle is fixed. During the cleaning process, the nozzle needs to maintain a stable position to ensure the consistency of the cleaning effect. After the bottom of the nozzle contacts the soaking liquid, by making the nozzle perform an eccentric circular motion, due to the irregularity of the eccentric circular motion, the cleaning blind area on the surface of the nozzle is reduced, ensuring that the entire surface of the nozzle can be effectively cleaned. At the same time, when the driving sleeve rotates, it drives the pulley ring to rotate, and the pulley ring rotation will contact the arc block, causing the driving sleeve to vibrate. The vibration can make the nozzle generate a more complex motion trajectory in the soaking liquid, accelerating the dissolution and shedding of dirt and blockages, thereby improving the cleaning efficiency.

[0014] (2) In this invention, through the setting of the soaking device, when the nozzle is soaked, the agent in the agent tank enters the telescopic pipeline through the movement of the soaking box, and then enters the soaking box. The function of automatically dispensing the agent can reduce manual intervention and improve the automation degree of the cleaning process, thereby improving production efficiency. During the soaking process, the cleaning liquid decomposes the ink, causing the ink to float on the surface of the cleaning liquid. At this time, the circular motion of the placement plate contacts the pressing rod, causing the pressing rod to drive the ink-absorbing cloth to move up and down reciprocally, so that the ink-absorbing cloth adsorbs the floating ink, preventing this ink from causing secondary pollution.

[0015] (3) In this invention, through the setting of the wiping device, after soaking, by releasing the fixation of the soaking box and moving it downward, there may be residual liquid attached to the surface of the nozzle at this time. When the soaking box moves, the rope is pulled. The rope causes the fixed end of the electric push rod to move forward along the slide rail through the movable pulley frame. After reaching a certain position, the output end of the electric push rod drives the wiping cotton to move back and forth, so as to wipe the nozzle. After wiping, the excess water can be removed, preventing the ink on the surface of the nozzle from drying up again and keeping the nozzle in a moist state, which helps to maintain the normal working state of the nozzle.

Detailed implementation manner

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figures 1 - 5 , an embodiment of the present invention is: A cleaning device for multiple spray heads of a digital inkjet printer, including a bottom plate 1 and a spray head 2, for cleaning the spray head 2, including: A slide bar frame 3, which is fixedly installed on the top of the bottom plate 1; A fixed ring 4, which is fixedly installed on the circumferential surface of the slide bar frame 3; An arc block 5, which is fixedly installed on the inner wall of the fixed ring 4; An eccentric circle 6, which is rotatably installed on the surface of the bottom plate 1; A driving sleeve 7, which is fixedly installed on the left side of the eccentric circle 6, so that due to the irregularity of the eccentric circular motion of the spray head 2 in the soaking liquid, the cleaning blind area on the surface of the spray head 2 is reduced, ensuring that the entire surface of the spray head 2 can be effectively cleaned; A pulley ring 8, which is fixedly installed on the circumferential surface of the driving sleeve 7, and the pulley ring 8 is used to generate vibrations when contacting the arc block 5; A placing plate 9, which is fixedly installed on the left side of the driving sleeve 7; A threaded rod 10, which is rotatably installed on the top of the placing plate 9; A clamping piece 11, which is threadedly installed on the circumferential surface of the threaded rod 10, so that the position of the spray head 2 is fixed. During the cleaning process, the spray head 2 needs to maintain a stable position to ensure the consistency of the cleaning effect; An elastic telescopic rod 12, the fixed end of the elastic telescopic rod 12 is slidably installed on the surface of the slide bar frame 3, and the movable end of the elastic telescopic rod 12 is fixedly installed on the top of the placing plate 9; The elastic telescopic rod 12 is used to make the device adapt to the rotation of the eccentric circle 6.

[0020] The pulley ring 8 contacts the arc block 5, and the jitter can cause the spray head 2 to generate a more complex movement trajectory in the soaking liquid, accelerating the dissolution and shedding of dirt and blockages, thereby improving the cleaning efficiency.

[0021] When this embodiment works, after removing the spray head 2 and placing it on the top of the placement plate 9, the clamping piece 11 is driven by rotating the threaded rod 10 to clamp it, so that the position of the spray head 2 is fixed. During the cleaning process, the spray head 2 needs to maintain a stable position to ensure the consistency of the cleaning effect. After contacting the bottom of the spray head 2 with the soaking liquid, the eccentric circle 6 is rotated by the motor. The rotation of the eccentric circle 6 causes the driving sleeve 7 to rotate. The rotation of the driving sleeve 7 drives the placement plate 9 to rotate. The rotation of the placement plate 9 causes the spray head 2 to perform eccentric circular motion. Due to the irregularity of the eccentric circular motion, the cleaning blind area on the surface of the spray head 2 is reduced, ensuring that the entire surface of the spray head 2 can be effectively cleaned. At the same time, when the driving sleeve 7 rotates, it drives the pulley ring 8 to rotate. The rotation of the pulley ring 8 contacts the arc block 5, causing the driving sleeve 7 to vibrate. The vibration can cause the spray head 2 to generate a more complex movement trajectory in the soaking liquid, accelerating the dissolution and shedding of dirt and blockages, thereby improving the cleaning efficiency.

[0022] Please refer to Figures 1 - 9 , on the basis of the above embodiment, in another embodiment of the present invention, a soaking device for soaking the spray head 2 and a wiping device for cleaning are provided on the bottom plate 1. The soaking device includes a soaking box 20, a pressing rod 21 and an ink-absorbing cloth 22. The soaking box 20 is slidably installed on the circumferential surface of the sliding rod frame 3. The pressing rod 21 is slidably installed on the inner wall of the soaking box 20. A first spring is provided between the pressing rod 21 and the soaking box 20 to drive the pressing rod 21 to reset by the first spring provided. The ink-absorbing cloth 22 is arranged on the surface of the pressing rod 21. A docking groove is opened on the outer wall of the soaking box 20. During soaking, the cleaning liquid decomposes the ink, causing the ink to float on the surface of the cleaning liquid. At this time, the circular motion of the placement plate 9 contacts the pressing rod 21, causing the pressing rod 21 to drive the ink-absorbing cloth 22 to move up and down reciprocally, so that the ink-absorbing cloth 22 adsorbs the floating ink, preventing this ink from causing secondary pollution.

[0023] The soaking device further includes a stirring rod 23 and a sliding plate 24. The stirring rod 23 is rotatably installed on the inner wall of the soaking box 20. A reciprocating spiral groove is opened on the circumferential surface of the stirring rod 23. The sliding plate 24 is threadedly installed on the circumferential surface of the stirring rod 23, which can cause the cleaning liquid in the soaking box 20 to flow and fluctuate, thereby increasing the contact frequency and contact area between the cleaning liquid and the surface of the spray head 2.

[0024] The soaking device further includes a medicine tank 25, a hollow block 251, a telescopic pipe 26 and a plug 27. The medicine tank 25 is fixedly installed on the surface of the slide bar frame 3. The hollow block 251 is fixedly installed at the bottom of the medicine tank 25. One side of the telescopic pipe 26 is fixedly installed at the bottom of the medicine tank 25, and the other side of the telescopic pipe 26 is fixedly installed on the inner wall of the soaking box 20. The plug 27 is slidably installed in the inner wall of the hollow block 251. The bottom of the plug 27 is set to be inclined. A second spring is arranged between the plug 27 and the hollow block 251. The second spring drives the plug 27 to fix and disassemble the soaking box 20.

[0025] The soaking device further includes a Y-shaped rod 28 and a sealing plug 29. The Y-shaped rod 28 is fixedly installed at the top of the plug 27. One side of the sealing plug 29 is slidably installed in the inner wall of the telescopic pipe 26, and the other side of the sealing plug 29 is fixedly installed on the surface of the Y-shaped rod 28 close to the soaking box 20. The function of automatically dispensing medicine can reduce manual intervention and improve the automation degree of the cleaning process, thereby improving production efficiency.

[0026] The wiping device includes a movable pulley frame 30, a slide rail frame 31 and an electric push rod 32. The movable pulley frame 30 is arranged on the top of the bottom plate 1. The slide rail frame 31 is fixedly installed on the top of the bottom plate 1. The fixed end of the electric push rod 32 is slidably installed on the circumferential surface of the slide rail frame 31. After soaking, by releasing the fixation of the soaking box 20 and moving it downward, there may be residual liquid attached to the surface of the nozzle 2 at this time.

[0027] The wiping device further includes a rope 33 and a wiping cotton 34. One side of the rope 33 is arranged at the fixed end of the electric push rod 32, and the other side of the rope 33 is arranged at the rear side of the soaking box 20. The rope 33 contacts the movable pulley frame 30. The wiping cotton 34 is fixedly installed at the output end of the electric push rod 32. After wiping, it can remove excess moisture, prevent the ink on the surface of the nozzle 2 from drying up again, keep the nozzle 2 in a wet state, and help maintain the normal working state of the nozzle 2.

[0028] During the operation of this embodiment, when the nozzle 2 is soaked, the soaking box 20 moves upward to contact the inclined surface of the insertion block 27, causing the insertion block 27 to move to the right while compressing the second spring. When the docking groove overlaps with the insertion block 27, the second spring resets to drive the insertion block 27 to insert into the docking groove. At this time, the position of the soaking box 20 is fixed. When the insertion block 27 moves, it drives the Y-shaped rod 28 to move. The movement of the Y-shaped rod 28 drives the sealing plug 29 to move, allowing the medicament in the medicament tank 25 to enter the telescopic pipeline 26 and then enter the soaking box 20. The function of automatically dispensing the medicament can reduce manual intervention and improve the automation level of the cleaning process, thereby improving production efficiency. During the soaking process, the stirring rod 23 is rotated by the motor to mix the medicament. While the stirring rod 23 rotates, the sliding plate 24 moves left and right reciprocally through the reciprocating spiral groove provided, which can cause the cleaning liquid in the soaking box 20 to flow and fluctuate, thereby increasing the contact frequency and contact area between the cleaning liquid and the surface of the nozzle 2. When soaking, the cleaning liquid decomposes the ink, causing the ink to float on the surface of the cleaning liquid. At this time, the circular motion of the placement plate 9 contacts the pressing rod 21, causing the pressing rod 21 to drive the ink-absorbing cloth 22 to move up and down reciprocally, enabling the ink-absorbing cloth 22 to adsorb the floating ink and prevent this ink from causing secondary pollution; After the soaking is completed, the soaking box 20 is moved downward after being unfixed. At this time, there may be residual liquid attached to the surface of the nozzle 2. When the soaking box 20 moves, the rope 33 is pulled. The rope 33 causes the fixed end of the electric push rod 32 to move forward along the slide rail frame 31 through the movable pulley frame 30. After reaching a certain position, the output end of the electric push rod 32 drives the wiping cotton 34 to move back and forth, so as to wipe the nozzle 2. After wiping, the excess water can be removed, preventing the ink on the surface of the nozzle 2 from drying up again and maintaining the wet state of the nozzle 2, which helps to maintain the normal working state of the nozzle 2.

[0029] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and deformations can be made to these embodiments without departing from the principles and spirit of the present invention.
