Description

Technical Field

[0001] The invention relates to the technical field of cleaning devices, and in particular to a high-efficiency roller cleaning device for a carton printing machine. Background Art

[0002] As we all know, the high-efficiency rollers for carton printing machines play an important role in transferring ink, applying pressure and conveying cartons during the carton printing process. It can be said that the high-efficiency rollers for carton printing machines are the key to carton printing. In order to ensure the quality of carton printing, when ink accumulates on the high-efficiency rollers for carton printing machines, the high-efficiency rollers for carton printing machines need to be cleaned. In order to facilitate the cleaning of the high-efficiency rollers for carton printing machines, we propose a high-efficiency roller cleaning device for carton printing machines.

[0003] After searching, the Chinese patent publication number CN215473871U discloses a high-efficiency cleaning structure for the printing roller of a printing press, which is roughly described as comprising a cleaning box, a guide rail, an electric slide, a dry ice blaster, a motor, a gear a, a gear b, a first vertical plate, a cleaning roller a, 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 the guide rail is slidably connected to the electric slide. The end of the electric slide away from the guide rail is fixedly connected to the dry ice blaster. A motor is fixedly installed on one side wall of the cleaning box through a base. The output end of the motor is connected to gear a, and gear a is meshed with gear b. Gear a and gear b are respectively connected to cleaning roller a and cleaning roller b. When in use, the printing roller of the printing press is placed in the gap between cleaning roller a and cleaning roller b, and the electric slide moves to move the dry ice blaster and clean the printing roller of the printing press. The surface of the brush roller is sprayed to achieve the effect of automatic cleaning. The Chinese patent announcement number CN210652333U discloses a printing roller cleaning device for a printing machine, which is roughly described as including a frame, a traveling device and a cleaning device. The frame is located on the right side of the printing roller, the traveling device includes a stepping motor, a slide rail and a support plate, the slide rail is arranged parallel to the printing roller, the support plate frame is slidably connected, the support plate 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 on the top of the vertical connecting plate, a partition is horizontally arranged in the middle of the cleaning chamber, a scraper is arranged on the upper surface of the left side of the partition, the nozzle cover of the spray gun enters the cleaning chamber, a dehumidification roller that contacts the printing roller is arranged at the bottom of the cleaning chamber, and a heating rod is arranged inside the dehumidification roller. When in use, the spray gun directly forms a spray cleaning relative to the printing roller.

[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.

[0023] For examples, see Figure 1-Figure 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.

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.

[0024] It should be further explained that the access component includes a synchronous shaft 22, and the two side plate frames 3 are fixedly connected to the synchronous shaft 22. The synchronous shaft 22 is rotatably connected to two bending arm frames 23, and the two bending arm frames 23 are installed with limited clamping structures, and the two limited clamping structures are respectively matched with the two shoulder shafts 2. The two bending arm frames 23 are rotatably connected to the telescopic support tube 24, and the two telescopic support tubes 24 are threadedly connected to the threaded support rods 25. The bottom ends of the two threaded support rods 25 are rotatably connected to the hinge blocks 26, and the two hinge blocks 26 are rotatably connected to the bottom supports 27. The two bending arm frames 23 are installed with adjustable tension structures, and the two adjustable tension structures are respectively connected to the two side plate frames 3. The two limited clamping structures include an arc support frame 28 and a synchronous drive frame 29. The two arc supports The frame 28 is fixedly connected to the two bending arm frames 23 respectively, and the two arc support frames 28 are rotatably connected with an upper swing limit frame 30 and a lower swing limit frame 31. The two synchronous drive frames 29 are respectively slidably connected to the two bending arm frames 23. The two synchronous drive frames 29 are provided with two extended auxiliary operation rings 48 to facilitate the pulling and pushing operation of the synchronous drive frames 29. The two synchronous drive frames 29 are fixedly connected with an upper connecting shaft 32 and a lower connecting shaft 33. The two upper connecting shafts 32 are rotatably connected to the two upper swing limit frames 30 respectively, and the two lower connecting shafts 33 are rotatably connected to the two lower swing limit frames 31 respectively. Through the design of the access component, it is convenient for the dust sticking component to form a relative bracket positioning installation relative to the target printing roller 1 to be cleaned, so that the printing roller 1 can be cleaned. During cleaning operations, there is no need to disassemble the shoulder shaft 2 relative to its installation position, which makes the operation more convenient and the versatility better. The two arc support frames 28 are fixedly connected with support wheels 34, and the two upper swing limit frames 30 and the two lower swing limit frames 31 are rotatably connected with adjustment wheels 35, so that the contact between the arc support frame 28 and the shoulder shaft 2, the contact between the upper swing limit frame 30 and the shoulder shaft 2, and the contact between the lower swing limit frame 31 and the shoulder shaft 2 are all rolling motions, and the rolling motion is used instead of the friction motion to reduce the friction loss of the shoulder shaft 2. The two synchronous drive frames 29 are both equipped with elastic double limiting mechanisms, and the two elastic double limiting mechanisms are respectively installed on the two bending arm frames 23. The two elastic double limiting mechanisms include external mounting seats 36, and the external mounting seats 36 are respectively connected to the two The ends of the two bending arm frames 23 that are close to each other are fixedly connected, and the two external mounting seats 36 are both rotatably connected with external rotating blocks 37, and the two external rotating blocks 37 are both fixedly connected with two-way limit springs 38, and the two two-way limit springs 38 are both fixedly connected with internal rotating blocks 39. The two synchronous driving frames 29 are both provided with center openings 40, and the two internal rotating blocks 39 are respectively rotatably connected in the two center openings 40. When the synchronous driving frame 29 moves on the bending arm frame 23 in a direction away from the arc support frame 28, and when the two-way limit spring 38 moves through the limit compression position, the two-way limit spring 38 will make the synchronous driving frame 29 have a tendency to move further away from the arc support frame 28 under the tendency of its own elastic extension. When the synchronous driving frame 29 is away from the arc support frame 28,Under the connection action of the upper connecting shaft 32, the corresponding upper swing limit frame 30 is formed to rotate and adjust relative to the corresponding arc support frame 28, and under the connection action of the lower connecting shaft 33, the corresponding lower swing limit frame 31 is formed to rotate and adjust relative to the corresponding arc support frame 28, so as to achieve the synchronous relative rotation movement of the upper swing limit frame 30 and the lower swing limit frame 31, so that the corresponding two adjusting wheels 35 move away from each other. Similarly, when the synchronous driving frame 29 moves on the bending arm frame 23 in the direction close to the arc support frame 28, and when the two-way limit spring 38 moves through the limit compression position again, the two-way limit The position spring 38 will make the synchronous drive frame 29 have a tendency to move closer to the arc support frame 28 under the tendency of its own elastic extension. When the synchronous drive frame 29 is close to the arc support frame 28, the corresponding upper swing limit frame 30 is rotated and adjusted relative to the corresponding arc support frame 28 under the connection action of the upper connecting shaft 32, and the corresponding lower swing limit frame 31 is rotated and adjusted relative to the corresponding arc support frame 28 under the connection action of the lower connecting shaft 33, so as to achieve the synchronous relative rotation movement of the upper swing limit frame 30 and the lower swing limit frame 31, so that the corresponding two adjusting wheels 35 move closer to each other.

[0025] It should be further explained that the two tension adjustment structures include a rotating connecting block 41 and a rotating connecting tube 42. The two rotating connecting blocks 41 are respectively rotatably connected to the two bending arm frames 23. The two rotating connecting tubes 42 are respectively rotatably connected to the two side plate frames 3. The two rotating connecting tubes 42 are slidably connected with step blocks 43. The two step blocks 43 are fixedly connected with tension springs 44. The two tension springs 44 are respectively fixedly connected to the two rotating connecting blocks 41. The two rotating connecting tubes 42 are rotatably connected with threaded rods 45. The two threaded rods 45 are respectively threadedly connected to the two step blocks 43, which can assist in limiting the relative angle between the bending arm frame 23 and the side plate frame 3. When the bending arm frame 23 is relative to When the printing roller 1 is installed in the form of a bracket, the relative force of the dust-adhesive transfer belt 8 at the contact point with the printing roller 1 can be adjusted. The two bending arm frames 23 are fixedly connected with operating inner bending rods 46, and the synchronous shaft 22 is fixedly connected with two operating outer bending rods 47. The two operating inner bending rods 46 are respectively matched with the two operating outer bending rods 47. By adjusting the relative distance between the adjacent operating outer bending rods 47 and the operating inner bending rods 46, the auxiliary control and adjustment of the rotation angle of the side panel frame 3 and the synchronous shaft 22 can be achieved. Auxiliary rotation caps 49 are fixedly connected to the threaded rod 45 and the threaded support rod 25, which facilitates the separate rotation adjustment of the threaded rod 45 and the threaded support rod 25.

[0026] The circulation pump 12, servo motor 9 and pressure sensor 17 in this embodiment are all conventional equipment purchased on the market and known to those skilled in the art. In the present invention, we only use them without improving their structure and function. For those skilled in the art, their setting method, installation method and electrical connection method only need to be debugged and operated according to the requirements of their instruction manual, and will not be described in detail here.

[0027] To sum up, the working principle of the high-efficiency roller cleaning device for a carton printing machine is as follows: when in use, the high-efficiency roller cleaning device for a carton printing machine is first carried to the desired location, and is mounted in a bracket relative to the target printing roller 1 that needs cleaning. During the bracket installation process, the operator first pulls the synchronous drive frame 29 relative to the bent arm frame 23 in a direction away from the arc support frame 28, so that the bidirectional limit spring 38 first enters a compressed state, and when the bidirectional limit spring 38 is compressed and passes through the shortest compression position, the pulling force acting on the synchronous drive frame 29 is released, and the elastically stretched bidirectional limit spring 38 Under the driving action, the synchronous driving frame 29 has a tendency to continue to move relative to the bending arm frame 23 until the synchronous driving frame 29 moves to the extreme position relative to the bending arm frame 23, so that the two upper and lower corresponding adjusting wheels 35 are separated from each other, so as to facilitate the subsequent shoulder shaft 2 to smoothly enter the area surrounded by the corresponding arc support frame 28, the upper swing limit frame 30 and the lower swing limit frame 31. Similarly, the adjustment of the two synchronous driving frames 29 is completed, and then the operator's palms of both hands respectively hold the two operating outer bending rods 47, and use the fingers of both hands to form a hook grip of the two operating inner bending rods 46, and adjust the hands The bending degree of the fingers forms the adjustment of the relative positions between the two operating inner curved rods 46 and the two operating outer curved rods 47, so as to achieve the relative angle adjustment of the two curved arm frames 23 relative to the synchronous shaft 22. Since the two side plate frames 3 are fixedly connected to the synchronous shaft 22, the relative angle adjustment between the side plate frames 3 and the curved arm frames 23 can be achieved, so as to facilitate the adaptation and insertion of the installation position of the matching printing cylinder 1 of the curved arm frames 23. After the insertion is completed, the operator retains one hand to maintain the relative grip and posture between the mutually coordinated set of operating inner curved rods 46 and operating outer curved rods 47, and pushes The synchronous driving frame 29 is moved closer to the arc support frame 28, so that the two-way limit spring 38 passes through the limit compression position again. Thereafter, the two-way limit spring 38 will have a tendency to push the synchronous driving frame 29 to further approach the arc support frame 28, so that the two upper and lower corresponding adjusting wheels 35 can move closer to each other, thereby achieving the effect of hugging the matching shoulder shaft 2, realizing the relative position limitation of the arc support frame 28 and the shoulder shaft 2, and then adjusting the height of the bracket formed by the telescopic support tube 24 and the threaded support rod 25, so that one end of the curved arm frame 23 is supported by the shoulder shaft 2 and the other end is supported by the telescopic support tube 24. The specific state is shown in the attached figure. Figure 1As shown, in order to facilitate the combination of the dust-adhesive transfer tape 8 with respect to the printing cylinder 1, the bent arm frame 23 after the completion of the bracket is generally inclined with one end close to the bottom of the printing cylinder 1 and one end away from the printing cylinder 1 being high.

[0028] Furthermore, after the installation of the bent arm bracket 23 is completed, under the action of the self-gravity of the two side plate brackets 3, the synchronous shaft 22 will rotate and adjust relative to the two bent arm brackets 23 to achieve the contact adaptation between the dust sticking belt 8 and the printing roller 1. According to the external space of the printing roller 1, the bottom end of the dust sticking belt 8 is appropriately adjusted to be inclined toward the end away from the printing roller 1, so that the dust sticking belt 8 can be pressed against the printing roller 1 by its own gravity, and the two outer protruding rollers 7 can also provide the dust sticking belt 8 with an outward protruding part to ensure the contact effect between the dust sticking belt 8 and the printing roller 1, so that the dust sticking belt 8 can form a better penetration with the installation space of the printing roller 1, and then first add cleaning liquid into the cleaning box 11, and the amount of cleaning liquid added is suitable to cover the connecting port of the suction elbow of the circulating pump 12 and not to form contact with the cleaning roller 5, so as to ensure that the cleaning liquid is normally extracted by the circulating pump 12, and also ensure that the cleaning roller 5 For effective cleaning of the dust-sticking transfer belt 8, the servo motor 9 and the driving system of the printing cylinder 1 are then started synchronously. The servo motor 9 moves through the driving shaft 10 to drive the driving roller 6 to rotate. The driving roller 6 rotates to drive the dust-sticking transfer belt 8 to move, so that the dust-sticking transfer belt 8 can form a synchronous movement relative to the printing cylinder 1, that is, the dust-sticking transfer belt 8 first moves close to the printing cylinder 1 until it contacts and then separates, forming adhesion to the debris on the printing cylinder 1, so as to achieve the purpose of cleaning the printing cylinder 1, and the debris transferred to the dust-sticking transfer belt 8 will be cleaned when the dust-sticking transfer belt 8 passes through the cleaning roller 5, so as to ensure the adhesion and cleaning effect when the dust-sticking transfer belt 8 moves again to contact with the printing cylinder 1. In order to reduce the damage of the printing cylinder 1 during the cleaning process, the dust-sticking transfer belt 8 should be made of a soft material, and in order to ensure the effective cleaning of the dust-sticking transfer belt 8 by the cleaning roller 5, the dust-sticking transfer belt 8 should be made of a material that can be soaked and penetrated by the cleaning liquid.

[0029] 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 circulating pump 12 will not be sprayed in the area covered by the side plate frame 3, which can ensure the smooth cleaning of the dust-sticking belt 8. During the movement of the dust-sticking belt 8 driven by the servo motor 9, when the dust-sticking belt 8 and the printing cylinder 1 have good synchronization, the relative deviation of the detection values ​​of the two pressure sensors 17 is small. When the rotation synchronization of the dust-sticking belt 8 and the printing cylinder 1 is poor, that is, the dust-sticking belt 8 and the printing cylinder 1 form a large relative movement trend at the contact point between the two pressure sensors 17, the detection values ​​of the two pressure sensors 17 will form a large deviation. According to the real-time detection values ​​of the two pressure sensors 17, the rotation speed of the servo motor 9 will be adjusted accordingly. For example, 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 means that the dust-sticking belt 8 has a relative deviation with respect to the printing cylinder 1. When the servo motor 9 has a faster movement trend, the servo motor 9 will reduce its speed to slow down the dust-sticking belt 8. When the detection value of a pressure sensor 17 in the forward direction of the servo motor 9 decreases and the detection value of the other pressure sensor 17 increases, it means that the printing roller 1 has a faster movement trend relative to the dust-sticking belt 8. The servo motor 9 will increase its speed to increase the speed of the dust-sticking belt 8, thereby forming an adaptive movement of the dust-sticking belt 8 and the printing roller 1. By rotating the threaded rod 45, the relative position between the step block 43 and the rotating connecting tube 42 can be adjusted, and the overall size of the step block 43, the rotating connecting block 41, the rotating connecting tube 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. The deformation tension of the tension spring 44 finally further controls the adjustment of the interaction force at the relative contact point between the dust-sticking belt 8 and the printing roller 1, thereby forming a better cleaning effect relative to the printing roller 1.
