A cyclic offset press cleaning and maintenance device

Abstract

The present invention discloses a cyclic offset printing machine cleaning and maintenance device, specifically relating to the technical field of offset printing machine maintenance. By setting up an ink printing device and a first installation cover, with the operation of the motor, the water pump in the water tank injects high-pressure liquid into the interior of the first installation cover through a first conduit, thereby treating the water entering the stirring device. The water entering the stirring device, after being treated, will return to the interior of the water tank along the third conduit again. This enables the maintenance device to achieve the cyclic use of liquid simply by starting the driving device and the high-speed centrifuge during use, and can recycle the ink washed off, thus improving the environmental protection effect of the maintenance device, avoiding the situation of a large amount of water resources and ink waste, and effectively reducing the damage of the ink printing cylinder through the liquid flushing method, thereby ensuring the cleaning efficiency of the maintenance device and the service life of the ink printing cylinder.

Description

Technical Field

[0001] The present invention relates to the technical field of offset press maintenance, and more specifically, the present invention relates to a circulating offset press cleaning and maintenance device. Background Art

[0002] Offset presses have been widely used in China and have now become the mainstream of the printing industry in China. When offset presses print, they first transfer the printed graphics and texts from the printing plate to the rubber cylinder, and then transfer them from the rubber cylinder to the paper, thereby improving the printing efficiency and quality.

[0003] Currently, when cleaning and maintaining an offset press, it is often necessary to remove the blanket from the rubber cylinder, or the blanket can be left on, and the rubber cylinder can be jogged or slowly rotated directly for cleaning. When cleaning manually, generally, first wipe with a water cloth, then wipe the blanket with a gasoline cloth, and finally wipe with a clean cloth. Manual cleaning is rather troublesome, with low efficiency and potential safety hazards. If there are operation errors, it is easy to cause additional damage to the blanket. Therefore, currently, expensive offset presses use automatic cleaning devices. However, automatic cleaning devices usually use an automatic cleaning cloth to continuously rub the blanket to achieve the cleaning effect. Long-term rubbing cleaning or improper pressure adjustment may cause irreversible damage to the blanket. For relatively small impurity particles, it is difficult to achieve a thorough cleaning effect, resulting in not only the risk of damage to the offset cylinder and the blanket, but also the difficulty in timely collecting the ink and impurities washed off. This not only easily causes economic losses due to the damage of the offset cylinder, but also makes it difficult to ensure the cleaning quality and achieve the effect of circulating cleaning. Therefore, it causes a waste of resources. Summary of the Invention

[0014] The beneficial effects of the present invention are as follows:

[0015] 1. The present invention is provided with an ink printing device, a stirring device, a driving device, a transmission device and a first mounting cover. As the motor operates, the water pump in the water tank injects high-pressure liquid into the interior of the first mounting cover through the first conduit, and then injects it into the outer shell of the ink printing machine through a number of water injection holes, so as to clean the surface of the ink printing cylinder by discharging the high-pressure liquid.

When the fan assembly operates, the fan assembly discharges air by injecting gas into the sealed connection shell, so that the air pressure inside the sealed connection shell rises rapidly. And when the gas enters the innermost second sliding plate through the through hole, the stain cleaning plates on both sides of the first sliding plate and the second sliding plate will turn outwards under the action of the elastic force of the spiral spring, so that the stain cleaning plates are attached to the surface of the ink printing cylinder.

Detailed implementation manners

[0027] 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 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.

[0028] As Figure 1-8As shown in the figure, the present invention provides a cyclic offset press cleaning and maintenance device, including a printing rubber device 1. Both sides of the printing rubber device 1 are fixedly connected with first mounting covers 2, and one side of each of the two first mounting covers 2 away from each other is fixedly connected with a sealing cover 3. The first mounting cover 2 is communicated with a first conduit 4 through the sealing cover 3. The two sides of the printing rubber device 1 are respectively fixedly connected with the opposite surfaces of two second mounting covers 5, and one side of each of the two second mounting covers 5 away from each other is fixedly connected with a plurality of sub-connecting pipes 6. A plurality of sub-connecting pipes 6 on the same side are communicated with the bottom end of the same second conduit 7. The second mounting cover 5 is communicated with the same second conduit 7 through a plurality of sub-connecting pipes 6. Due to the provision of the sub-connecting pipes 6 and the second conduit 7, when the liquid enters the second mounting cover 5 along the water pumping holes 102, it can enter the interiors of a plurality of sub-connecting pipes 6 simultaneously, avoiding the situation that the liquid is difficult to enter the high-speed centrifuge 8 along the second conduit 7 due to the viscosity of the liquid or blockage by impurities, thereby ensuring the stability of the high-maintenance device during operation;

[0029] A plurality of sub-connecting pipes on the same side and the other ends of the two second conduits 7 are communicated with the feed inlet of the same high-speed centrifuge 8. The printing rubber device 1 is fixedly connected to a base 17, and the high-speed centrifuge 8 is fixedly connected to the base 17. The printing rubber device 1 includes a printing rubber machine housing 101. A plurality of water pumping holes 102 are provided on both the left and right sides of the printing rubber machine housing 101. The two sides of the printing rubber machine housing 101 are respectively fixedly connected with the two second mounting covers 5. The position of the second mounting cover 5 corresponds to the position of the water pumping holes 102. A plurality of water injection holes 103 are provided on both sides of the printing rubber machine housing 101. The two sides of the printing rubber machine housing 101 are respectively fixedly connected with the opposite surfaces of the two first mounting covers 2. The position of the first mounting cover 2 corresponds to the position of the water injection holes 103;

[0030] Due to the provision of a plurality of water injection holes 103, when the water pump discharges the liquid, it is blocked by the printing rubber machine housing 101, causing the pressure of the liquid flow to increase rapidly. When the liquid is discharged along the water injection holes 103 with a smaller aperture, the pressure of the liquid discharge will increase, enabling the pressure of the liquid discharge to be effectively increased when the liquid is pumped and discharged through the water pump in the base 17, thereby ensuring the flushing effect of the printing rubber cylinder 106 by the liquid discharge method of the maintenance device and avoiding the situation of impurity residue on the surface of the printing rubber cylinder 106;

[0031] The outer shell 101 of the glue printing machine is provided with mounting holes 104, and the inner wall of the mounting holes 104 is fixedly connected to the sealing connection shell 20. The front surface of the outer shell 101 of the glue printing machine is provided with a feeding hole 105. Both sides of the inner wall of the feeding hole 105 are fixedly connected with electric regulators 37. The outer shell 101 of the glue printing machine is connected to the door panel 38 through the electric regulators 37. The outer shell 101 of the glue printing machine is fixedly connected with a sensor 36. The sensor 36 receives the signal sent by the driving device 12. The sensor 36 sends out a signal, and the electric regulator 37 receives the signal sent by the sensor 36. A number of glue printing cylinders 106 are arranged inside the outer shell 101 of the glue printing machine. When the motor 121 operates, the sensor 36 will receive the signal sent by the motor 121, so that when the fan assembly 13 operates and the inside of the outer shell 101 of the glue printing machine is cleaned by liquid, the liquid is not likely to overflow, and at the same time, the sealing performance of the outer shell 101 of the glue printing machine during use is improved;

[0032] The liquid discharge port of the high-speed centrifuge 8 is connected to the stirring device 9 through a pipeline. The output shaft of the stirring device 9 is drivingly connected to the bottom end of the driving shaft 10. The top end of the driving shaft 10 is fixedly connected with a transmission device 11. The driving shaft 10 is drivingly connected to the driving device 12 through the transmission device 11. A liquid injection valve 34 is arranged on the stirring device 9. A one-way valve 35 is arranged on the back surface of the outer shell 101 of the glue printing machine. An inclined groove 39 is opened on the base 17. A placement groove 40 is opened on one side of the base 17. The position of the placement groove 40 corresponds to the position of the oil outlet pipe 19;

[0033] Due to the setting of the one-way valve 35, when the motor 121 runs in reverse, the fan assembly 13 will extract the gas inside the outer shell 101 of the glue printing machine through the first slide plate 24 and the second slide plate 28. At this time, the outside gas will enter the inside of the maintenance device along the one-way valve 35, avoiding the situation that the fan assembly 13 is damaged due to the difficulty in meeting the operation of the fan assembly 13 with the gas inside the outer shell 101 of the glue printing machine;

[0034] The transmission device 11 includes a first transmission wheel 111. The first transmission wheel 111 is fixedly connected to the outside of the driving device 12. A transmission belt 112 is adjusted outside the first transmission wheel 111. The first transmission wheel 111 is drivingly connected to a second transmission wheel 113 through the transmission belt 112. The second transmission wheel 113 is fixedly connected to the top end of the driving shaft 10;

[0035] Due to the setting of the first transmission wheel 111 and the second transmission wheel 113, when the driving device 12 operates, the stirring device 9 can operate together with the fan assembly 13 and the driving device 12, thus ensuring the operation effect of the maintenance device, eliminating the need for manual startup or adjustment of the stirring device 9, and thus reducing the difficulty in using the maintenance device;

[0036] The driving device 12 includes a motor 121. The bottom end of the motor 121 is in transmission connection with the fan assembly 13. The output end of the motor 121 is in transmission connection with the first transmission wheel 111. An installation frame 122 is fixedly connected to the outside of the motor 121. The bottom end of the installation frame 122 is fixedly connected to the fan assembly 13;

[0037] A water tank 16 is fixedly connected inside the base 17. The other end of the first conduit 4 is communicated with the water tank 16. The stirring device 9 is communicated with the connector 15 through the third conduit 14 from the water outlet. The connector 15 is fixedly connected to the outside of the water tank 16. The oil outlet of the high-speed centrifuge 8 is communicated with the control valve 18. The other end of the control valve 18 is communicated with the oil outlet pipe 19. Due to the provision of the high-speed centrifuge 8 and the water tank 16, during the use of the maintenance device, only the driving device 12 and the high-speed centrifuge 8 need to be started to realize the recycling of the liquid, and the ink washed off can be recovered, thereby improving the environmental protection effect of the maintenance device, avoiding a large amount of waste of water resources and ink, and effectively reducing the damage of the printing rubber cylinder 106 through the liquid flushing method. The bottom end of the driving device 12 is in transmission connection with the output end of the fan assembly 13. The driving device 12 is fixedly connected above the fan assembly 13. The fan assembly 13 is communicated with the sealed connection shell 20. The sealed connection shell 20 is fixedly connected to the printing rubber device 1;

[0038] A plurality of first installation grooves 21 are formed inside the sealed connection shell 20. Both sides of the inner walls of the plurality of first installation grooves 21 are provided with first sliding grooves 22. A first sliding block 23 is slidably arranged in the first sliding groove 22. The opposite surfaces of the two first sliding blocks 23 located in the same first sliding groove 22 are fixedly connected to both sides of the same first sliding plate 24. A plurality of second sliding plates 28 are arranged inside the first sliding plate 24. The plurality of second sliding plates 28 are sequentially sleeved inside the first sliding plate 24. Two second sliding grooves 26 are formed inside each of the plurality of second sliding plates 28;

[0039] Due to the provision of the second sliding groove 26, the second sliding block 27, the first sliding groove 22 and the first sliding block 23, the first sliding plate 24 and the second sliding plate 28 are not easily separated during the moving process, ensuring the stability of the connection between the first sliding plate 24 and the sealed connection shell 20, and at the same time restricting the moving distance of the first sliding plate 24 and the second sliding plate 28;

[0040] A second sliding block 27 is fixedly connected inside the second sliding groove 26. The second sliding plate 28 on the outer side is slidably connected to the second sliding plate 28 on the inner side through the second sliding groove 26 and the second sliding block 27. Through holes 25 are formed in both the first sliding plate 24 and the second sliding plate 28. Second mounting grooves 29 are formed in the front and back surfaces of the first sliding plate 24 and the second sliding plate 28. Bearings 30 are clamped on both sides of the inner wall of the second mounting groove 29. The same rotating shaft 31 is sleeved in the two bearings 30 in the same second mounting groove 29. A coil spring 32 is sleeved outside the bearing 30. The two ends of the coil spring 32 are fixedly connected to the bearing 30 and the rotating shaft 31 respectively. A stain cleaning plate 33 is fixedly connected outside the bearing 30. The stain cleaning plate 33 is clamped in the second mounting groove 29. Due to the arrangement of the coil spring 32, the second sliding plate 28 and the stain cleaning plate 33, when the gas enters the innermost second sliding plate 28 through the through hole 25, the stain cleaning plates 33 on both sides of the first sliding plate 24 and the second sliding plate 28 will flip outwards under the action of the elastic force of the coil spring 32, so that the stain cleaning plate 33 fits on the surface of the printing rubber cylinder 106. During the use of the maintenance device, not only can the printing rubber cylinder 106 be rinsed with high-pressure liquid, but also the remaining impurities on the surface of the printing rubber cylinder 106 can be diluted by contact, avoiding the situation of impurity residue, and thus improving the cleaning and maintenance effect of the maintenance device on the printing rubber cylinder 106.

[0041] Working principle of the present invention:

[0042] When it is necessary to clean and maintain the printing machine, only need to start the motor 121. When the motor 121 runs, the inductor 36 will receive the signal sent by the motor 121. At this time, the inductor 36 will transmit the signal to the electric regulator 37, so that the two electric regulators 37 quickly drive the door plate 38 to move, so that the two door plates 38 flip towards each other along the electric regulator 37 and seal the feeding hole 105.

[0043] And as the motor 121 operates, the motor 121 will drive the fan assembly 13 and the first driving wheel 111 to rotate simultaneously. Since the first driving wheel 111 rotates, it will drive the second driving wheel 113 to rotate at high speed through the transmission belt 112. At the same time, the water pump in the water tank 16 will inject high-pressure liquid into the interior of the first mounting cover 2 through the first conduit 4, and then inject it into the printing rubber machine housing 101 through a number of water injection holes 103, so as to clean the surface of the printing rubber cylinder 106 through the discharge of high-pressure liquid. After the liquid enters the interior of the printing rubber machine housing 101 and cleans the printing rubber cylinder 106, it will drip above the base 17 under the action of gravity. And due to the operation of the fan assembly 13, the pressure inside the printing rubber machine housing 101 rises rapidly, so that the liquid will enter the sub-conduit 6 and the second conduit 7 along the water extraction hole 102, and be quickly injected into the high-speed centrifuge 8 along the second conduit 7. At this time, the high-speed centrifuge 8 is started, so that the high-speed centrifuge 8 centrifuges the liquid entering its interior. And because the mass specific gravity of the printing ink and water is different, the printing ink can be quickly separated from the water, so that the liquid enters the stirring device 9 along the pipeline, and the printing ink will be discharged through the control valve 18. By injecting an appropriate amount of precipitant and disinfectant into the stirring device 9, the water entering the stirring device 9 is treated, and the water entering the stirring device 9 will return to the water tank 16 again along the third conduit 14 after being treated;

[0044] Since the fan assembly 13 discharges air by injecting gas into the interior of the sealed connection housing 20 during operation, the air pressure inside the sealed connection housing 20 rises rapidly. And when the gas enters the innermost second slide plate 28 through the through hole 25, the innermost second slide plate 28 will move downward. And as the second slide plate 28 moves to the limit position, the innermost second slide plate 28 will drive the remaining second slide plates 28 and the first slide plate 24 to move downward. And when the remaining second slide plates 28 and the first slide plate 24 both move to the limit position, the stain cleaning plates 33 on both sides of the first slide plate 24 and the second slide plates 28 will flip outward under the elastic force of the coil spring 32, so that the stain cleaning plates 33 are attached to the surface of the printing rubber cylinder 106;

[0045] When it is necessary to recycle the first slide plate 24 and the second slide plates 28, just reverse-start the motor 121, so that the fan assembly 13 runs in reverse. When the fan assembly 13 extracts the air inside the first slide plate 24 and the second slide plates 28, it will drive the second slide plates 28 and the first slide plate 24 to reset. The stain cleaning plates 33 will contact the adjacent second slide plates 28 or the first slide plate 24 and be recycled into the second installation groove 29. And as the second slide plates 28 and the first slide plate 24 gradually move, the outer second slide plates 28 and the sealed connection housing 20 can scrape the water stains and stains remaining on the surface of the stain cleaning plates 33 so that they drip onto the base 17.
