Description

Technical Field

[0001] The invention relates to the field of printing presses, and in particular to an ink adding device and a method for the ink adding device of a printing press. Background Art

[0002] In the printing industry, the ink filling device of the printing press plays a vital role in the printing quality and efficiency. The ink filling method of early printing presses was relatively simple, mostly using the method of manually pouring ink. This method is not only inefficient, but also difficult to ensure the accuracy of the amount of ink added each time, which can easily lead to ink waste or insufficient ink filling, affecting the printing effect. With the development of printing technology, some automatic ink filling devices have emerged, but these early devices have many problems. In terms of ink quality assurance, traditional ink filling devices lack an effective impurity filtering mechanism. Ink often contains impurities such as pigment particles that are not fully dissolved, dust mixed in during the production process, etc. After these impurities enter the printing machine, they are easy to clog the nozzle, causing defects in the printed pattern and reducing the printing quality. In addition, the ink in the traditional device is prone to precipitation during the ink filling process, making the ink concentration uneven and affecting the consistency of the printed color. In terms of ink tube maintenance, traditional ink refilling devices do not take into account the problem that ink tubes need to be cleaned due to impurities attached during long-term use. Once a large amount of impurities adhere to the inner wall of the ink tube, it will not only hinder the flow of ink and reduce the efficiency of ink refilling, but may also cause ink leakage and damage the equipment. When the ink tube needs to be replaced or cleaned, the operation process of the traditional device is cumbersome and requires manual removal and installation of the ink tube, which consumes a lot of time and manpower. In addition, traditional ink filling devices also have deficiencies in power transmission and equipment stability. For example, the mechanism that drives the ink tube to move or switch is often underpowered, unstable in operation, prone to jamming or failure, affecting the continuity and accuracy of ink filling. Moreover, there is a lack of effective collaborative working mechanism between the various components of the device, and it cannot be flexibly adjusted according to the characteristics of the ink and printing requirements, which reduces the versatility and adaptability of the device. As the printing market's requirements for printing quality and efficiency continue to increase, it is urgent to develop an efficient, intelligent and stable ink-filling device for printing presses.

DETAILED DESCRIPTION

[0017] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0018] refer to Figures 1 to 8 , an ink adding device for a printing press, comprising a printing press body 1, an ink storage box 2 arranged beside the printing press body 1, an ink adding box 3 arranged beside the ink storage box 2, and a fixed plate 14 fixedly arranged on a side of the ink storage box 2 close to the ink adding box 3, and further comprising: The ink tank 3 is provided with a stirring mechanism 4, and a plurality of ink tubes 10 are formed in an array at equal angles along the circumferential direction of the fixed plate 14. A filter screen 11 is fixedly connected to one end of each ink tube 10 close to the ink tank 2 (refer to Figure 8 ,because Figure 8 The ink tube 10 in the figure has been rotated 90 degrees, so the filter 11 in the figure can be directly seen from the end of the ink tube 10). The lower end of the ink tank 3 is provided with a fan 12 (such as Figure 3As shown in the figure, a rotation mechanism 13 for driving a plurality of ink tubes 10 to move along the center direction of the fixed plate 14 is arranged on the fixed plate 14, and the rotation mechanism 13 includes a rotating drum 21 coaxially arranged to rotate with the fixed plate 14, and the rotating drum 21 drives the plurality of ink tubes 10 to move along the center direction of the fixed plate 14 when rotating, and a dust removal mechanism 30 is arranged beside the rotating drum 21, and the dust removal mechanism 30 includes an adapter frame 31 for providing support and two claws 49 for clamping and positioning the ink tubes 10, each claw 49 is respectively fixedly connected to a claw seat 35, and the two claws Sliding frames 41 are slidably arranged above and below the seat 35, respectively. The sliding frame 41 located above the two claws 49 is fixedly connected with a water spray pipe 42, and the sliding frame 41 located below the two claws 49 is rotatably arranged with a roller brush 48. After the ink tube 10 is clamped by the two claws 49, the water spray pipe 42 approaches the ink tube 10 from top to bottom and sprays water to the filter screen 11 to ensure that impurities blocked in the filter holes of the filter screen 11 can be washed away, while the roller brush 48 approaches the ink tube 10 from bottom to top, and brushes the impurities remaining on the inner wall of the ink tube 10 during the rotation process.

[0019] When the device is in operation, ink is slowly injected from the ink tube 10 into the ink storage tank 2. The filter 11 provided in the ink tube 10 is made of high-precision material, and its mesh size is accurately calculated, which can effectively intercept impurities in the ink (such as incompletely dissolved pigment agglomerates, tiny particles mixed in during production and transportation, etc.) without hindering the normal flow of ink. As the ink is continuously added, impurities in the ink continue to adhere to the inner wall of the ink tube 10 and the filter 11. Although the filter 11 intercepts impurities to ensure the quality of the ink in the ink storage tank 2, the accumulation of impurities gradually increases until the filter holes of the filter 11 are blocked, and the rotation mechanism 13 on the fixed plate 14 starts to switch the ink tube 10.

[0020] After the ink tube 10 is switched, the two claws 49 of the impurity removal mechanism 30 move closer to the ink tube 10 and hold it tightly (the inner side of the claws 49 is a non-slip rubber pad to ensure that the ink tube 10 is firmly clamped without damaging it). Then the sliding frame 41 located above the two claws 49 drives the water spray pipe 42 to dock with the ink tube 10. After the docking is completed, the water spray pipe 42 sprays out high-pressure water to preliminarily rinse the ink tube 10 and the filter 11, washing away most of the attached impurities. Then, the roller brush 48 rotatably set on the sliding frame 41 located below the two claws 49 begins to rotate. The roller brush 48 is made of soft material and has strong adsorption. In conjunction with the water sprayed from the water spray pipe 42, the inner wall of the ink tube 10 is further rolled and cleaned, and the residual impurities on the inner wall of the ink tube 10 and the filter 11 are completely removed.

[0021] After the cleaning process is completed, the cleaned ink tube 10 continues to move to the side of the fan 12 under the drive of the rotation mechanism 13. The fan 12 adjusts the wind speed and temperature in advance according to the material and residual moisture of the ink tube 10. The hot air blown by the fan 12 blows evenly on the inner wall of the ink tube 10, quickly evaporates the residual moisture, and prepares for the next ink filling, ensuring that the entire ink filling process is smooth and efficient, and ensuring the stable operation of the printing machine body 1.

[0022] In order to facilitate the two ends of the ink tube 10 to be connected to the ink adding tank 3 and the ink storage tank 2 respectively, the following features are also specifically provided: The output end of the ink adding box 3 and the input end of the ink storage box 2 are respectively connected to the corrugated cover 7 (the corrugated cover 7 at the ink adding box 3 and the ink storage box 2 has the same structure, so Figure 5 Only the corrugated cover 7 at the ink storage tank 2 is shown), the side where the ink adding tank 3 and the ink storage tank 2 are close to each other is fixedly connected with a rod seat 6, the ends where the two corrugated covers 7 are close to each other are respectively fixedly connected with a card plate 8, and the ends where the two card plates 8 are far away are respectively provided with two electric push rods 5, the movable ends of the two electric push rods 5 are fixedly connected to the card plate 8, and the fixed ends of the two electric push rods 5 are fixedly connected to the rod seat 6. When the electric push rods 5 are started, the movable ends of the electric push rods 5 push the card plate 8 to move. Since the output end of the ink adding tank 3 and the input end of the ink storage tank 2 are respectively fixedly connected to the card plate 8 through the corrugated cover 7, the movement of the card plate 8 drives the corrugated cover 7 to extend or contract (when the ink tube 10 is switched, the corrugated cover 7 will contract to avoid the moving ink tube 10), so that the two ends of the ink tube 10 can accurately dock with the ink adding tank 3 and the ink storage tank 2. The bellows 7 has good flexibility, which can not only adapt to the fine adjustment of the position when the ink tube 10 is connected, but also effectively prevent ink leakage, ensure the sealing of the ink filling process, ensure the smooth progress of the ink filling operation, and provide a reliable connection basis for subsequent ink delivery.

[0023] In order to drive the drum 21 to rotate, the following features are also specifically provided: The rotation mechanism 13 also includes a fixed seat 15, a main motor 16, a main pulley 17, a secondary pulley 18, a main gear 19 and a main gear ring 20. The fixed seat 15 is arranged on a side of the fixed plate 14 close to the ink storage box 2 (such as Figure 6 As shown in the figure, the fixed seat 15 is fixedly connected to the fixed plate 14, the main motor 16 is fixedly connected to the lower end of the ink storage box 2, the main pulley 17 is fixedly connected to the output end of the main motor 16 coaxially, the secondary pulley 18 is arranged above the main pulley 17 and is rotatably connected to the side wall of the ink storage box 2, the main pulley 17 is connected to the secondary pulley 18 through a belt drive, and the main gear 19 is fixedly connected to the secondary pulley 18 coaxially (as shown in the figure). Figure 8As shown in the figure, the main gear ring 20 is rotatably connected to the fixed seat 15 and is coaxially fixedly connected to the rotating drum 21. The main gear ring 20 is meshed with the main gear 19. After the main motor 16 is started, the main motor 16 drives the secondary pulley 18 to rotate through the main pulley 17, and the secondary pulley 18 drives the main gear ring 20 to rotate through the main gear 19. When the main gear ring 20 rotates, it drives the rotating drum 21 to rotate, thereby realizing the movement of the ink tube 10 along a predetermined trajectory, meeting the requirements of the ink adding device for switching and positioning the ink tube 10.

[0024] In order to achieve that when the ink tube 10 moves to the side where the two claws 49 are close to each other, the following features are also provided: The rotation mechanism 13 further includes a main arc-shaped tooth 28, a secondary arc-shaped tooth 29, a plurality of tooth seats 22, a plurality of first bevel teeth 23, a plurality of second bevel teeth 24, a plurality of pipe racks 25 and a plurality of driving gears 27. The tooth seat 22 is fixedly connected to the rotating drum 21, and the main arc-shaped tooth 28 is fixedly connected to one side of the edge of the fixed disk 14 (such as Figure 8 As shown in the figure, the secondary arc-shaped teeth 29 are fixedly connected to one side of the center of the fixed plate 14, one end of a plurality of tube racks 25 are respectively fixedly connected to a plurality of ink tubes 10, a plurality of first bevel teeth 23 are respectively rotatably connected to a plurality of tooth seats 22, the first bevel teeth 23 are coaxially fixedly connected to the tube rack 25, a plurality of second bevel teeth 24 are respectively rotatably connected to a plurality of tooth seats 22, the second bevel teeth 24 are meshed with the first bevel teeth 23, a plurality of driving gears 27 are respectively rotatably connected to a plurality of tooth seats 22, the driving gear 27 is coaxially fixedly connected to the second bevel teeth 24, and the driving gear 27 is meshed with the primary arc-shaped teeth 28 and the secondary arc-shaped teeth 29 in sequence when the tooth seat 22 moves. When the ink tube 10 moves with the rotating drum 21, the driving gear 27 is meshed with the primary arc-shaped teeth 28 and the secondary arc-shaped teeth 29 in sequence. When the driving gear 27 is meshed with the main arc-shaped teeth 28, the driving gear 27 drives the first bevel teeth 23 to rotate through the second bevel teeth 24, thereby causing the tube holder 25 and the ink tube 10 to rotate. At this time, the ink tube 10 is changed from a horizontal setting to a vertical setting (such as Figure 5 When the driving gear 27 is meshed with the secondary arc-shaped teeth 29, the ink tube 10 is changed from a vertical setting to a horizontal setting, in preparation for the subsequent ink filling work.

[0025] In order to improve the stability of the pipe rack 25, the following features are also specifically provided: A magnetic ring 26 is rotatably provided on the tooth seat 22. The magnetic ring 26 is fixedly connected to the first bevel tooth 23 and is attracted to the tooth seat 22 by magnetic force. Due to the magnetic attraction between the magnetic ring 26 and the tooth seat 22, when the first bevel tooth 23 rotates under the action of power, the magnetic force of the magnetic ring 26 can suppress the shaking of the first bevel tooth 23 and the tube holder 25 connected thereto during the rotation process. During the movement and rotation of the ink tube 10, this magnetic adsorption effect ensures that the tube holder 25 always maintains a relatively stable posture, avoiding the ink tube 10 from colliding with other components due to shaking, improving the stability of the ink tube 10 during the movement and cleaning process, ensuring the reliability of the ink adding device, and extending the service life of the equipment.

[0026] In order to drive the two claws 49 to approach the ink tube 10 in a vertical state so as to facilitate the cleaning of the ink tube 10, the following features are also specifically provided: The impurity removal mechanism 30 also includes an auxiliary motor 32, an auxiliary gear 33 and two power gears 34. The auxiliary motor 32 is fixedly connected to the middle part of the adapter frame 31 (such as Figure 7 As shown in the figure, the auxiliary gear 33 is rotatably connected to the middle of the adapter frame 31 and is coaxially fixedly connected to the output end of the auxiliary motor 32. The two power gears 34 are rotatably arranged in the middle of the adapter frame 31 and mesh with each other. The power gear 34 close to the auxiliary gear 33 meshes with the auxiliary gear 33. The two power gears 34 are respectively fixedly connected to the two claw seats 35. After the auxiliary motor 32 is started, the auxiliary motor 32 drives the power gear 34 to rotate through the auxiliary gear 33. When the power gear 34 rotates, it drives another power gear 34 meshed with it to rotate. The two power gears 34 rotate in opposite directions, that is, when the power gear 34 rotates, it drives the two claw seats 35 to move toward each other, so that the two claws 49 are close to the ink tube 10 in a vertical state.

[0027] In order to drive the two sliding frames 41 to move, so that after the two claws 49 hold the ink tube 10 tightly, the water spray pipe 42 and the roller brush 48 can cooperate with each other to achieve thorough cleaning of the ink tube 10, the following features are specifically provided: The impurity removal mechanism 30 also includes two connecting frames 36, two secondary motors 37, two screw rods 38, two screw sleeves 39 and two limit rods 40, one end of the limit rod 40 is fixedly connected to the claw seat 35 (such as Figure 3As shown in the figure), the other end is fixedly connected to the connecting frame 36, the secondary motor 37 is fixedly connected to the side of the connecting frame 36 away from the claw seat 35, one end of the screw rod 38 is rotatably connected to the connecting frame 36, and the other end is rotatably connected to the claw seat 35, the output end of the secondary motor 37 is fixedly connected to the screw rod 38 coaxially, the screw sleeve 39 is threadedly connected to the screw rod 38 and fixedly connected to the sliding frame 41, and the sliding frame 41 is slidably connected to the limiting rod 40. When the secondary motor 37 is started, the secondary motor 37 will drive the screw sleeve 39 to move through the screw rod 38, and the screw sleeve 39 will drive the sliding frame 41 to move. During the movement of the sliding frame 41, it will be limited by the limiting rod 40 to ensure that the sliding frame 41 can only move linearly along the direction of the limiting rod 40. After the two claws 49 hold the ink tube 10, the movement of the sliding frame 41 enables the water spray pipe 42 and the roller brush 48 to approach the ink tube 10 and cooperate in cleaning. By accurately controlling the rotation of the secondary motor 37, the positions of the water spray pipe 42 and the roller brush 48 can be flexibly adjusted to improve the cleaning efficiency and effect.

[0028] In order to provide clean water to the water spray pipe 42, the following features are also specifically provided: The impurity removal mechanism 30 further includes a water tank 44 and a buffer pipe 43. The buffer pipe 43 is fixedly connected to the upper portion of the adapter frame 31 and is slidably connected to the water spray pipe 42 (eg, Figure 2 As shown in FIG. 1 , the water tank 44 is fixedly connected to the adapter frame 31 and is connected to the buffer tube 43 through a hose. When the filter screen 11 needs to be flushed, the water tank 44 delivers clean water to the buffer tube 43. When the water spray pipe 42 flushes the ink tube 10, the buffer tube 43 can adapt to the position change of the water spray pipe 42 during the movement process, ensuring the continuous supply of clean water, providing sufficient water source guarantee for the efficient cleaning of the ink tube 10, and ensuring that the impurity removal mechanism 30 can successfully complete the task of cleaning the ink tube 10.

[0029] In order to drive the roller brush 48 to rotate and collect the sediment after cleaning, the following features are also specifically provided: The impurity removal mechanism 30 also includes a collection barrel 45, a collection cover 46 and a motor 47. The motor 47 is fixedly connected to the sliding frame 41 near the roller brush 48. The output end of the motor 47 is fixedly connected to the roller brush 48 coaxially. The collection cover 46 is coaxially arranged with the roller brush 48 and fixedly connected to the sliding frame 41. The lower end of the collection cover 46 is connected to the collection barrel 45. When the motor 47 is started and drives the roller brush 48 to rotate at a high speed, the roller brush 48 cleans the ink tube 10 during the rotation process, brushes off the impurities on the inner wall of the ink tube 10 and the filter screen 11, and the collection cover 46 can effectively collect the sediment brushed off by the roller brush 48 when cleaning the ink tube 10. The lower end of the collection cover 46 is connected to the collection barrel 45, so that the sediment can fall smoothly into the collection barrel 45. This design realizes the integration of the rotation cleaning of the roller brush 48 and the collection of sediment, avoids the sediment scattered everywhere to pollute the working environment, and also facilitates the centralized treatment of the sediment, improving the convenience of cleaning and maintenance of the equipment.

[0030] A method for operating an ink adding device of a printing press, further comprising the following operating steps: S1: When ink needs to be added, the stirring mechanism 4 in the ink tank 3 is started and the ink in the ink tank 3 is stirred (such as Figure 3 As shown), to prevent different ink concentrations due to precipitation of impurities when the ink enters the ink storage tank 2; S2: During the ink adding process, the filter 11 intercepts impurities in the ink to improve the quality of the ink in the ink storage tank 2. During this process, the impurities in the ink will adhere to the inner wall of the ink tube 10; S3: When the filter holes of the filter screen 11 are blocked, the rotation mechanism 13 starts and drives the ink tube 10 to move, and the uncleaned ink tube 10 moves to the side where the two claws 49 are close to each other. The two claws 49 hold the ink tube 10 tightly under the action of the impurity removal mechanism 30, and then the water spray pipe 42 and the roller brush 48 are close to each other and cooperate with each other to clean the ink tube 10 and the filter screen 11; S4: The cleaned ink tube 10 is dried by the fan 12 when it moves to the side of the fan 12, so as to prepare for the next ink filling.

[0031] The working principle of the device is that when the printer body 1 needs to be filled with ink, the stirring mechanism 4 in the ink tank 3 is first started. The stirring mechanism 4 continuously stirs the ink in the ink tank 3 to prevent the impurities from settling due to long-term static ink, and ensures that the concentration of the ink entering the ink tank 2 is uniform, thereby providing a guarantee for high-quality printing operations. Subsequently, the ink flows from the ink adding tank 3 to the ink storage tank 2 through the ink tube 10. The filter 11 at one end of the ink tube 10 near the ink storage tank 2 plays an important role. Its high-precision material and precisely designed mesh can effectively intercept various impurities in the ink, such as undissolved pigment agglomerates, tiny particles mixed in during production and transportation, etc., and significantly improve the quality of the ink in the ink storage tank 2. However, as the ink adding process continues, impurities gradually adhere to the inner wall of the ink tube 10, especially the position of the filter 11. When the filter holes of the filter 11 are blocked to a certain extent, affecting the normal flow rate of the ink, the rotation mechanism 13 on the fixed plate 14 is activated.

[0032] The main motor 16 in the rotation mechanism 13 drives the rotating drum 21 to rotate through the transmission of the main pulley 17, the secondary pulley 18, the main gear 19 and the main gear ring 20, thereby moving the ink tube 10 along the center direction of the fixed plate 14 to achieve the switching of the ink tube 10. During the movement of the ink tube 10, the driving gear 27 meshes with the main arc-shaped teeth 28 and the secondary arc-shaped teeth 29 in sequence, so that the ink tube 10 rotates when moving, and the angle of the ink tube 10 is adjusted. When the uncleaned ink tube 10 moves between the two claws 49, the impurity removal mechanism 30 starts to work. The auxiliary motor 32 drives the auxiliary gear 33 and the power gear 34 to make the two claws 49 hold the ink tube 10 tightly. Then, the secondary motor 37 drives the screw 38 to drive the sliding frame 41 to move, so that the water spray pipe 42 and the roller brush 48 are close to the ink tube 10. The water spray pipe 42 sprays high-pressure water to preliminarily rinse the ink tube 10 and the filter screen 11, and then the roller brush 48 rotates under the drive of the motor 47, and cooperates with the water flow to further clean the inner wall of the ink tube 10 and the filter screen 11. The sediment produced by cleaning is collected by the collection cover 46 and falls into the collection bucket 45 through the lower end of the collection cover 46. After the cleaning process is completed, the cleaned ink tube 10 moves to the side of the fan 12, and the hot air blown by the fan 12 quickly dries the ink tube 10 to prepare for the next ink filling.
