Description

Technical Field

[0001] The present invention relates to the technical field of cleaning devices, and particularly relates to an efficient drum cleaning device for a carton printing machine. Background Art

[0002] As is well known, the efficient drum for a carton printing machine plays important roles such as transferring ink, applying pressure, and conveying cartons during the carton printing process. It can be said that the efficient drum for a carton printing machine is the key to forming carton printing. To ensure the quality of carton printing, when ink adheres and accumulates on the efficient drum for a carton printing machine, it is necessary to clean the efficient drum for a carton printing machine. To facilitate the cleaning of the efficient drum for a carton printing machine, we propose an efficient drum cleaning device for a carton printing machine.

[0003] After retrieval, the patent with the Chinese patent publication number CN215473871U discloses an efficient cleaning structure for a printing drum of a printing machine, which is generally described as including a cleaning box, a guide rail, an electric sliding table, a dry ice injector, a motor, gear a, gear b, a first vertical plate, cleaning roller a, cleaning roller b, a second vertical plate, and a drain pipe. A guide rail is provided on one side of the cleaning box, and an electric sliding table is slidably connected to the guide rail. The end of the electric sliding table away from the guide rail is fixedly connected to the dry ice injector. A motor is fixedly installed on one side wall of the cleaning box through a base, and the output end of the motor is connected to gear a. Gear a is meshed with gear b, and gear a and gear b are respectively connected to cleaning roller a and cleaning roller b. When in use, the printing drum of the printing machine is placed in the gap between cleaning roller a and cleaning roller b, and the electric sliding table moves to make the dry ice injector move and spray the surface of the printing drum of the printing machine, achieving the effect of automatic cleaning. The patent with the Chinese patent publication number CN210652333U discloses a printing drum cleaning device for a printing machine, which is generally described as including a frame, a traveling device, and a cleaning device. The frame is located on the right side of the printing drum. The traveling device includes a stepping motor, a slide rail, and a pallet. The slide rail is arranged parallel to the printing drum, and the pallet is slidably connected to the frame. The pallet is electrically connected to the stepping motor. The cleaning device includes a spray gun, a water tank, and a cleaning chamber. The spray gun is fixed at the top of a vertical connecting plate. A partition is horizontally arranged in the middle of the cleaning chamber. A scraping plate is arranged on the upper surface of the left side of the partition. The nozzle cover plate of the spray gun enters the interior of the cleaning chamber. A dehumidifying roller that contacts the printing drum is arranged at the bottom of the cleaning chamber, and a heating rod is arranged inside the dehumidifying roller. When in use, direct spraying and cleaning are formed relative to the printing drum through the spray gun.

[0004] Although the above-mentioned existing technical solutions can perform a cleaning operation on the printing cylinder of a printing press, the former requires that the printing cylinder of the printing press be removed from the printing press and placed in the gap between cleaning roller a and cleaning roller b for cleaning, and the cleaning preparation work needs to be further simplified. The principle of the latter is to clean the printing cylinder directly by spraying water, but considering the characteristic of the printing cylinder sticking to powder, it is difficult to effectively clean the printing cylinder if the water spray pressure is too small, and too high a water spray pressure will cause the printing cylinder to consume itself, and its practicality needs to be further enhanced.

[0037] For the embodiment, please refer to Figures 1 - 15A high-efficiency roller cleaning device for a carton printing machine includes a printing roller 1, shoulder shafts 2 are provided at both ends of the printing roller 1, and a dust sticking and transferring component. The dust sticking and transferring component includes two side plate frames 3. The two side plate frames 3 are quickly assembled relative to the two shoulder shafts 2 through an access component. The two side plate frames 3 are fixedly connected by a synchronous frame 4. A cleaning roller 5, a driving roller 6 and two outer rollers 7 are rotatably connected between the two side plate frames 3. A dust sticking and transferring belt 8 is transmission-connected between the cleaning roller 5, the driving roller 6 and the two outer rollers 7.

A driving shaft 10 is used to drive the driving roller 6 to rotate, and an elastic pressure piece is installed between the driving shaft 10 and the driving roller 6. The elastic pressure piece is used for the operation control of the servo motor 9. Through the design of the dust sticking and transferring component, the matching printing roller 1 forms an effective erasing and cleaning, and the cleaning reliability is good while the impact on the printing roller 1 itself is small. The elastic pressure piece includes a ridge 14, and the ridge 14 is fixedly connected to the driving shaft 10. A ridge groove 15 is provided in the driving roller 6.

Matching, the two pressure sensors 17 are electrically connected to the controller of the servo motor 9, and the elastic pressure piece is equipped to adjust the matching speed of the servo motor 9 according to the movement trend of the dust-sticking transfer belt 8 relative to the printing roller 1, so that the dust-sticking transfer belt 8 can form a suitable speed matching movement relative to the printing roller 1, avoiding damage to the surface of the printing roller 1 due to excessive relative movement of the dust-sticking transfer belt 8 relative to the contact point of the printing roller 1. The two side plate frames 3 are rotatably connected to the cleaning box 11, and a circulating pump 12 is installed outside the cleaning box 11. The suction end of the circulating pump 12 is connected to the cleaning box 11, and the pump outlet end of the circulating pump 12 is connected to the cleaning roller 5. The cleaning roller 5 is rotatably matched with a covering sealing plate 13, and the covering sealing plate 13 is fixedly connected between the two side plate frames 3, and the ends of the two side plate frames 3 that are away from each other are respectively connected with a swivel shaft 19 and a swivel pipe 20. Two circular branch holes 21 are provided on the cleaning box 11. The swivel shaft 19 is connected to a circular branch hole 21 located on the rear side, and the swivel pipe 20 is connected to a circular branch hole 21 located on the front side. The swivel pipe 20 is connected to the pump outlet end of the circulating pump 12, and the swivel pipe 20 is rotatably connected to the cleaning roller 5, and the cleaning roller 5 is connected to the swivel pipe 20. Through the cooperation of the circulating pump 12, the cleaning roller 5 and the covering sealing plate 13, the matching dust sticking transfer belt 8 forms a corresponding cleaning operation, so that the dust sticking transfer belt 8 has better self-cleaning performance, and the cleaning stability of the dust sticking transfer belt 8 relative to the printing roller 1 is also better.

[0038] It should be further noted that the access component includes a synchronous shaft 22. Both side plate frames 3 are fixedly connected to the synchronous shaft 22. Two bent arm frames 23 are rotatably connected to the synchronous shaft 22. Limiting and clamping structures are installed on both bent arm frames 23. The two limiting and clamping structures respectively match the two shoulder shafts 2. Both bent arm frames 23 are rotatably connected with telescopic support cylinder 24. Threaded support rods 25 are threadedly connected to both telescopic support cylinder 24. The bottom ends of both threaded support rods 25 are rotatably connected with hinge blocks 26. Both hinge blocks 26 are rotatably connected with bottom supports 27. Adjusting tension structures are installed on both bent arm frames 23. The two adjusting tension structures are respectively connected to the two side plate frames 3. Both limiting and clamping structures include arc support frames 28 and synchronous drive frames 29. The two arc support frames 28 are respectively fixedly connected to the two bent arm frames 23. An upper swing limiting frame 30 and a lower swing limiting frame 31 are rotatably connected to both arc support frames 28. The two synchronous drive frames 29 are respectively slidably connected to the two bent arm frames 23. Two outer extension auxiliary operation rings 48 are provided on both synchronous drive frames 29, which is convenient for the operation and force application of pulling and pushing the synchronous drive frame 29. An upper connecting shaft 32 and a lower connecting shaft 33 are fixedly connected to both synchronous drive frames 29. The two upper connecting shafts 32 are respectively rotatably connected to the two upper swing limiting frames 30. The two lower connecting shafts 33 are respectively rotatably connected to the two lower swing limiting frames 31. Through the design of the access component, it is convenient for the dust adhesion and rotation component to be positioned and installed relative to the target printing cylinder 1 to be cleaned, so that the printing cylinder 1 does not need to be disassembled relative to its installation position during the cleaning operation, the operation is more convenient, and the versatility is also better. Support rollers 34 are fixedly connected inside both arc support frames 28. Adjusting rollers 35 are rotatably connected inside both upper swing limiting frames 30 and both lower swing limiting frames 31, so that the contact movement between the arc support frame 28 and the shoulder shaft 2, the contact movement between the upper swing limiting frame 30 and the shoulder shaft 2, and the contact movement between the lower swing limiting frame 31 and the shoulder shaft 2 are all rolling movements. Using rolling movement to replace frictional movement reduces the frictional loss of the shoulder shaft 2. Both synchronous drive frames 29 are equipped with elastic double limiting mechanisms. The two elastic double limiting mechanisms are respectively installed on the two bent arm frames 23. Both elastic double limiting mechanisms include external mounting seats 36. The external mounting seats 36 are respectively fixedly connected to the mutually close ends of the two bent arm frames 23. External rotating blocks 37 are rotatably connected inside both external mounting seats 36. Both external rotating blocks 37 are fixedly connected with double-direction limiting springs 38. Both double-direction limiting springs 38 are fixedly connected with internal rotating blocks 39. Central openings 40 are provided on both synchronous drive frames 29. The two internal rotating blocks 39 are respectively rotatably connected inside the two central openings 40. When the synchronous drive frame 29 moves away from the arc support frame 28 on the bent arm frame 23, and when the double-direction limiting spring 38 moves through the extreme compression position, the double-direction limiting spring 38 will, under the trend of its own elastic elongation, make the synchronous drive frame 29 have a further tendency to move away from the arc support frame 28. When the synchronous drive frame 29 moves away from the arc support frame 28,Under the connection action of the upper connecting shaft 32, a rotational adjustment of the corresponding upper swing limiting frame 30 relative to the corresponding arc support frame 28 is formed. Under the connection action of the lower connecting shaft 33, a rotational adjustment of the corresponding lower swing limiting frame 31 relative to the corresponding arc support frame 28 is formed, so as to achieve the synchronous relative rotational movement of the upper swing limiting frame 30 and the lower swing limiting frame 31, and make the corresponding two adjusting rotating wheels 35 move away from each other relatively. Similarly, when the synchronous driving frame 29 moves on the bent arm frame 23 in a direction close to the arc support frame 28, and when the two-way limiting spring 38 moves through the extreme compression position again, under the tendency of its own elastic elongation, the two-way limiting spring 38 will make the synchronous driving frame 29 have a tendency to move closer to the arc support frame 28. When the synchronous driving frame 29 approaches the arc support frame 28, under the connection action of the upper connecting shaft 32, a rotational adjustment of the corresponding upper swing limiting frame 30 relative to the corresponding arc support frame 28 is formed. Under the connection action of the lower connecting shaft 33, a rotational adjustment of the corresponding lower swing limiting frame 31 relative to the corresponding arc support frame 28 is formed, so as to achieve the synchronous relative rotational movement of the upper swing limiting frame 30 and the lower swing limiting frame 31, and make the corresponding two adjusting rotating wheels 35 move closer to each other relatively.,

[0039] It should be further explained that both of the two adjusting tension structures include a rotating connecting block 41 and a rotating connecting cylinder 42. The two rotating connecting blocks 41 are respectively rotatably connected inside the two bent arm frames 23. The two rotating connecting cylinders 42 are respectively rotatably connected to the two side plate frames 3. A stepped block 43 is slidably connected inside each of the two rotating connecting cylinders 42. A tension spring 44 is fixedly connected to each of the two stepped blocks 43. The two tension springs 44 are respectively fixedly connected to the two rotating connecting blocks 41. A threaded rod 45 is rotatably connected inside each of the two rotating connecting cylinders 42. The two threaded rods 45 are respectively threadedly connected to the two stepped blocks 43, which can assist in limiting the relative angle between the bent arm frame 23 and the side plate frame 3. When the bent arm frame 23 is installed as a support relative to the printing cylinder 1, the relative acting force at the contact between the dust sticking belt 8 and the printing cylinder 1 can be adjusted. An operating inner bent rod 46 is fixedly connected to each of the two bent arm frames 23. Two operating outer bent rods 47 are fixedly connected to the synchronous shaft 22. The two operating inner bent rods 46 respectively match the two operating outer bent rods 47. By adjusting the relative distance between the adjacent operating outer bent rod 47 and the operating inner bent rod 46, the rotational angle of the side plate frame 3 and the synchronous shaft 22 can be assisted in controlling and adjusting. An auxiliary rotating cap 49 is fixedly connected to both the threaded rod 45 and the threaded support rod 25, which facilitates the respective rotational adjustment of the threaded rod 45 and the threaded support rod 25.

[0040] The circulation pump 12, servo motor 9, and pressure sensor 17 in this embodiment are all conventional devices well-known to those skilled in the art and purchased on the market. In the present invention, we only use them without improving their structures and functions. Their setting methods, installation methods, and electrical connection methods can be debugged and operated by those skilled in the art according to the requirements of their user manuals, and thus will not be elaborated here.

[0041] In summary, the working principle of the high-efficiency drum cleaning device for the carton printing machine is as follows: during use, first carry the high-efficiency drum cleaning device for the carton printing machine to the location where it is needed and install it as a bracket relative to the target printing drum 1 that needs cleaning operation. During the bracket installation process, the operator first pulls the synchronous drive frame 29 away from the arc support frame 28 relative to the bent arm frame 23, so that the bidirectional limit spring 38 first enters the compressed state. And when the bidirectional limit spring 38 is compressed past the shortest compression position, release the pulling force acting on the synchronous drive frame 29. Under the driving action of the elastically extending bidirectional limit spring 38, the synchronous drive frame 29 has a tendency to continue moving relative to the bent arm frame 23 until the synchronous drive frame 29 moves to the limit position relative to the bent arm frame 23, realizing the mutual separation of the two adjusting rotating wheels 35 corresponding up and down, so as to facilitate the subsequent smooth entry of the shoulder shaft 2 into the area enclosed by the corresponding arc support frame 28, upper swing limit frame 30, and lower swing limit frame 31. Similarly, complete the adjustment of the two synchronous drive frames 29. Then, the operator's palms of both hands respectively hold the two operating outer bent rods 47, and respectively form the hook grip of the two operating inner bent rods 46 through the fingers of both hands, and adjust the relative positions between the two operating inner bent rods 46 and the two operating outer bent rods 47 by adjusting the bending degrees of the fingers of both hands, so as to achieve the relative angle adjustment of the two bent arm frames 23 relative to the synchronous shaft 22. Since the two side plate frames 3 are both fixedly connected to the synchronous shaft 22, the relative angle between the side plate frame 3 and the bent arm frame 23 can be adjusted, so as to facilitate the adaptive adjustment and insertion of the installation position of the bent arm frame 23 matching the printing drum 1. After the insertion is completed, the operator retains the relative grip and posture maintenance between a set of the mutually cooperating operating inner bent rod 46 and operating outer bent rod 47 with one hand, and pushes the synchronous drive frame 29 closer to the arc support frame 28, so that the bidirectional limit spring 38 passes through the extreme compression position again. Thereafter, the bidirectional limit spring 38 will have a tendency to push the synchronous drive frame 29 closer to the arc support frame 28 further. In this way, the mutual approaching movement of the two adjusting rotating wheels 35 corresponding up and down can be formed, so as to achieve the effect of tightly holding the matching shoulder shaft 2 and realize the relative position limitation between the arc support frame 28 and the shoulder shaft 2. Then, adjust the height of the bracket formed by the cooperation of the telescopic support cylinder 24 and the threaded support rod 25, so that one end of the bent arm frame 23 is supported by the shoulder shaft 2 and the other end is supported by the telescopic support cylinder 24. The specific state is as shown in the appendix Figure 1As shown in the figure, to facilitate the combination of the dust adhesion belt 8 with the printing drum 1, the overall bent arm frame 23 after the completion of the bracket presents an inclined posture with the bottom end near the printing drum 1 being lower and the end far from the printing drum 1 being higher.

[0042] Furthermore, after the installation of the bent arm frame 23 bracket is completed, under the action of the self - gravity of the two side plate frames 3, the synchronous shaft 22 will rotate and adjust relative to the two bent arm frames 23 to achieve the contact adaptation between the dust adhesion belt 8 and the printing drum 1. According to the external space of the printing drum 1, the bottom end of the dust adhesion belt 8 is appropriately adjusted to incline towards the end far from the printing drum 1, so that the dust adhesion belt 8 can rest on the printing drum 1 by its own gravity, and the two out - reaching rollers 7 can also provide a protruding part for the dust adhesion belt 8 to ensure the contact effect between the dust adhesion belt 8 and the printing drum 1, enabling the dust adhesion belt 8 to form a better penetration with the installation space of the printing drum 1. Then, first add cleaning liquid into the cleaning box 11. The amount of cleaning liquid added should cover the communication port of the suction elbow of the circulation pump 12 and not contact the cleaning roller 5, which can ensure the normal extraction of the cleaning liquid by the circulation pump 12 and also ensure the effective cleaning of the dust adhesion belt 8 by the cleaning roller 5. Then, start the servo motor 9 and the driving system of the printing drum 1 simultaneously. The movement of the servo motor 9 drives the driving roller 6 to rotate through the driving shaft 10, and the rotation of the driving roller 6 drives the dust adhesion belt 8 to move, so that the dust adhesion belt 8 can move synchronously relative to the printing drum 1, that is, the dust adhesion belt 8 moves closer to and then contacts and separates from the printing drum 1, adhering to the sundries on the printing drum 1 to achieve the purpose of cleaning the printing drum 1. And the sundries transferred to the dust adhesion belt 8 will be cleaned when the dust adhesion belt 8 passes through the cleaning roller 5 to ensure the adhesion cleaning effect when the dust adhesion belt 8 moves to contact the printing drum 1 again. To reduce the damage of the printing drum 1 during the cleaning process, the dust adhesion belt 8 should be made of a soft material. And to ensure the effective cleaning of the dust adhesion belt 8 by the cleaning roller 5, the dust adhesion belt 8 should be made of a material that can be infiltrated by the cleaning liquid.

[0043] Furthermore, during the cleaning operation, due to the shielding effect of the side plate frame 3 on the cleaning roller 5, the cleaning liquid sent into the cleaning roller 5 by the circulation pump 12 will not be ejected in the area covered by the side plate frame 3, which can ensure the smooth cleaning of the dust adhesion belt 8. During the movement of the dust adhesion belt 8 driven by the servo motor 9, when the dust adhesion belt 8 has good synchronism with the printing cylinder 1, the relative deviation of the detection values of the two pressure sensors 17 is relatively small. When the rotational synchronism between the dust adhesion belt 8 and the printing cylinder 1 is poor, that is, when a large relative movement trend is formed at the contact between the dust adhesion belt 8 and the printing cylinder 1, it will cause a large deviation in the detection values of the two pressure sensors 17. According to the real-time detection values of the two pressure sensors 17, the rotational speed of the servo motor 9 will be adjusted in a follow-up manner. For example, if the detection value of one pressure sensor 17 in the forward rotation direction of the servo motor 9 increases while the detection value of the other pressure sensor 17 decreases, it indicates that the dust adhesion belt 8 has a faster movement trend relative to the printing cylinder 1, and the servo motor 9 will reduce its rotational speed to decelerate the dust adhesion belt 8. When the detection value of one pressure sensor 17 in the forward rotation direction of the servo motor 9 decreases while the detection value of the other pressure sensor 17 increases, it indicates that the printing cylinder 1 has a faster movement trend relative to the dust adhesion belt 8, and the servo motor 9 will increase its rotational speed to accelerate the dust adhesion belt 8, forming an adaptive movement between the dust adhesion belt 8 and the printing cylinder 1. And by rotating the threaded rod 45, the relative position between the stepped block 43 and the rotating connecting cylinder 42 can be adjusted, and the overall size formed by the cooperation of the stepped block 43, the rotating connecting block 41, the rotating connecting cylinder 42 and the tension spring 44 can be adjusted, thereby achieving the limitation of the relative angle between the side plate frame 3 and the bent arm frame 23. Finally, through the deformation tension of the tension spring 44, the mutual force at the relative contact between the dust adhesion belt 8 and the printing cylinder 1 is further controlled, forming a better cleaning effect relative to the printing cylinder 1.

The scope of the present invention is defined by the appended claims and their equivalents.
