Description

Technical Field

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

[0002] In the printing industry, the ink filling device of a printing press plays a crucial role in printing quality and efficiency. In the early days, the ink filling method of printing presses was relatively simple, mostly using the method of manually pouring ink. This method not only has low efficiency, but it is also very difficult to ensure the accuracy of the ink filling amount each time, easily causing ink waste or insufficient ink filling, affecting the printing effect. With the development of printing technology, some automated ink filling devices have emerged, but these early devices have many problems.

[0003] In terms of ink quality assurance, traditional ink filling devices lack an effective impurity filtering mechanism. Ink often contains impurities such as undissolved pigment particles and dust mixed in the production process. When these impurities enter the printing press, they are likely to clog the nozzles, resulting in defects in the printed pattern and reducing the printing quality. Moreover, the ink in traditional devices is prone to precipitation during the ink filling process, making the ink concentration uneven and affecting the consistency of printing colors.

[0004] In terms of ink tube maintenance, traditional ink filling devices do not consider the problem that the ink tube needs to be cleaned due to impurity attachment 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 ink flow, reduce the ink filling efficiency, but may also cause ink leakage and damage the equipment. When the ink tube needs to be replaced or cleaned, the operation process of traditional devices is cumbersome, requiring manual disassembly and installation of the ink tube, consuming a lot of time and manpower.

[0005] In addition, traditional ink filling devices also have deficiencies in power transmission and equipment stability. For example, the mechanism that drives the movement or switching of the ink tube often has insufficient power and unstable operation, prone to jamming or malfunction, affecting the continuity and accuracy of ink filling. Moreover, there is no effective collaborative working mechanism between the various components of the equipment, and it cannot be flexibly adjusted according to the characteristics of the ink and printing requirements, reducing the versatility and adaptability of the equipment.

[0006] With the continuous improvement of the requirements for printing quality and efficiency in the printing market, it is urgent to develop an efficient, intelligent, and stable ink filling device for printing presses. Summary of the Invention

[0019] A method for operating an ink filling device of a printing press further includes the following operating steps:

[0020] S1: When ink needs to be added, the stirring mechanism in the ink tank is activated to stir the ink in the ink tank to prevent the ink from having different concentrations due to precipitation of impurities when the ink enters the ink storage tank;

[0021] S2: During the ink filling process, the filter intercepts impurities in the ink to improve the ink quality in the ink tank. During this process, impurities in the ink will adhere to the inner wall of the ink tube;

[0022] S3: When the filter holes are clogged, the rotation mechanism starts and drives the ink tube to move. The uncleaned ink tube moves to the side where the two claws are close to each other. The two claws clamp the ink tube under the action of the impurity removal mechanism. Then the water spray pipe and roller brush approach and cooperate with each other to clean the ink tube and filter.

[0023] S4: The cleaned ink tube is dried by the fan when it moves to the side of the fan, so as to prepare for the next ink filling.

[0024] The beneficial effects of the present invention compared with the prior art are as follows:

[0025] First: By setting a high-precision filter on the ink tube, this device can effectively intercept impurities in the ink, significantly improve the quality of the ink in the ink storage tank. Compared with traditional ink filling devices, it greatly reduces the printing pattern defects caused by nozzle blockage due to impurities, improves the printing quality. At the same time, the setting of the filter prolongs the service life of the printer nozzle, reduces the equipment maintenance cost, saves capital investment for printing enterprises, and improves the economic benefits of the enterprises;

[0026] Second: The stirring mechanism in the ink filling tank continuously stirs the ink during the ink filling process to prevent the ink from precipitating and ensure the uniformity of the ink concentration. This makes the colors more stable and consistent during the printing process, avoids the printing color deviation problems caused by uneven ink concentration. Compared with the traditional ink filling method without stirring the ink, it greatly improves the color quality of the printed products, meets the market demand for high-quality printed materials, helps printing enterprises enhance product competitiveness, and wins more customer orders;

[0027] Third: The coordinated work of the rotation mechanism and the impurity removal mechanism realizes the automatic switching and cleaning of the ink tube. When the ink tube filter is blocked, the rotation mechanism automatically drives the ink tube to move, sending the uncleaned ink tube to the impurity removal mechanism for cleaning. The impurity removal mechanism can efficiently remove impurities on the inner wall of the ink tube and the filter through the cooperation of the water spray pipe and the rotary brush. This design greatly improves the work efficiency, reduces the labor cost compared with the traditional manual cleaning of the ink tube, and at the same time ensures the cleaning effect of the ink tube, ensuring the smooth progress of the ink filling process.

[0038] To further understand the features, technical means, specific purposes and functions achieved by the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0039] Refer to Figures 1 to 8 , an ink adding device for a printing press, including a printing press body 1, an ink storage tank 2 arranged beside the printing press body 1, an ink adding tank 3 arranged beside the ink storage tank 2, and a fixed disk 14 fixedly arranged on one side of the ink storage tank 2 close to the ink adding tank 3. It further includes:

[0040] A stirring mechanism 4 is arranged inside the ink adding tank 3. A plurality of ink pipes 10 are formed by equiangular array along the circumferential direction of the fixed disk 14. One end of each ink pipe 10 close to the ink storage tank 2 is fixedly connected with a filter screen 11 (here refer to Figure 8 [[ID=, because the ink pipe 10 in Figure 8 has been rotated by 90°, so the filter screen 11 in this figure can be directly seen from the end of the ink pipe 10). A fan 12 for drying the ink pipe 10 is arranged at the lower end of the ink adding tank 3 (as shown in Figure 3As shown in FIG. 1 , a rotation mechanism 13 is provided on the fixed plate 14 for driving the plurality of ink tubes 10 to move along the center direction of the fixed plate 14. The rotation mechanism 13 includes a rotating drum 21 coaxially rotatable with the fixed plate 14. When the rotating drum 21 rotates, the plurality of ink tubes 10 are driven to move along the center direction of the fixed plate 14. A dust removal mechanism 30 is provided beside the rotating drum 21. 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 fixedly connected to a claw seat 35. The two claws Sliding frames 41 are slidably provided above and below the seat 35, respectively. A water spray pipe 42 is fixedly connected to the sliding frame 41 located above the two claws 49, and a roller brush 48 is rotatably provided on the sliding frame 41 located below the two claws 49. 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 on 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 impurities remaining on the inner wall of the ink tube 10 during the rotation process.

[0041] During operation, ink is slowly injected from the ink tube 10 into the ink reservoir 2. The filter 11 within the ink tube 10 is constructed of high-precision materials, with precisely calculated mesh size. This effectively intercepts impurities in the ink (such as incompletely dissolved pigment clumps and tiny particles introduced during production and transportation) without obstructing the normal flow of ink. As ink is added, impurities in the ink continuously adhere to the inner wall of the ink tube 10 and the filter 11. While the filter 11 intercepts these impurities, ensuring the quality of the ink in the ink reservoir 2, the accumulation of these impurities gradually increases until the pores of the filter 11 become clogged, at which point the rotation mechanism 13 on the fixed plate 14 activates to switch the ink tubes 10.

[0042] After the ink tube 10 is switched, the two claws 49 of the impurity removal mechanism 30 move toward the ink tube 10 and securely grip it. (The inside of the claws 49 is lined with non-slip rubber pads, ensuring a secure grip without damaging the ink tube 10.) The sliding frame 41, located above the claws 49, then directs the water pipe 42 to dock with the ink tube 10. Once docked, the water pipe 42 sprays a high-pressure stream of water, initially flushing the ink tube 10 and filter 11 and removing most adhering impurities. Next, the rotating roller brush 48, mounted on the sliding frame 41 below the claws 49, begins to rotate. Made of a soft, highly absorbent material, the roller brush 48, combined with the water from the water pipe 42, further cleans the inner wall of the ink tube 10 and filter 11, thoroughly removing any remaining impurities.

[0043] After the cleaning process is completed, the cleaned ink tube 10 continues to move to the side of the blower 12 under the drive of the rotation mechanism 13. The blower 12 adjusts the wind speed and temperature in advance according to the material of the ink tube 10 and the residual moisture condition. The hot air blown by the blower 12 evenly blows the inner wall of the ink tube 10, quickly evaporating the residual moisture, preparing for the next ink filling, ensuring the smooth and efficient operation of the entire ink filling process, and guaranteeing the stable operation of the printing press body 1.

[0044] In order to facilitate the connection of both ends of the ink tube 10 to the ink filling box 3 and the ink storage box 2 respectively, the following features are specifically set:

[0045] Corrugated covers 7 are respectively fixedly connected to the output end of the ink filling box 3 and the input end of the ink storage box 2 (the corrugated covers 7 at the ink filling box 3 and the ink storage box 2 have the same structure, so Figure 5 only the corrugated cover 7 at the ink storage box 2 is shown). A rod seat 6 is fixedly connected to the side of the ink filling box 3 and the ink storage box 2 close to each other. At the ends of the two corrugated covers 7 close to each other, clamping plates 8 are respectively fixedly connected. At the ends of the two clamping plates 8 away from each other, two electric push rods 5 are respectively arranged. The movable ends of the two electric push rods 5 are fixedly connected to the clamping plates 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 clamping plates 8 to move. Since the output end of the ink filling box 3 and the input end of the ink storage box 2 are respectively fixedly connected to the clamping plates 8 through the corrugated covers 7, the movement of the clamping plates 8 drives the corrugated covers 7 to stretch or contract (when the ink tube 10 is switched, the corrugated covers 7 will contract to facilitate avoiding the moving ink tube 10), enabling both ends of the ink tube 10 to accurately dock with the ink filling box 3 and the ink storage box 2. The corrugated covers 7 have good flexibility, can not only adapt to the position fine-tuning during the connection of the ink tube 10, but also effectively prevent ink leakage, guarantee the sealing performance during the ink filling process, ensure the smooth progress of the ink filling operation, and provide a reliable connection basis for the subsequent ink delivery.

[0046] In order to drive the rotating drum 21 to rotate, the following features are specifically set:

[0047] The rotation mechanism 13 further includes a fixed seat 15, a main motor 16, a main belt pulley 17, a secondary belt pulley 18, a main gear 19 and a main gear ring 20. The fixed seat 15 is arranged on the side of the fixed disk 14 close to the ink storage box 2 (as Figure 6 shown), the fixed seat 15 is fixedly connected to the fixed disk 14, the main motor 16 is fixedly connected to the lower end of the ink storage box 2, the main belt pulley 17 is coaxially fixedly connected to the output end of the main motor 16, the secondary belt pulley 18 is arranged above the main belt pulley 17 and is rotatably connected to the side wall of the ink storage box 2, the main belt pulley 17 and the secondary belt pulley 18 are connected by belt drive, and the main gear 19 is coaxially fixedly connected to the secondary belt pulley 18 (as Figure 8As shown in the figure, the main gear ring 20 is rotatably connected to the fixed seat 15 and fixedly connected to the rotating cylinder 21 coaxially. The main gear ring 20 meshes with the main gear 19. After the main motor 16 is started, the main motor 16 drives the auxiliary pulley 18 to rotate through the main pulley 17. The auxiliary 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 cylinder 21 to rotate, thereby realizing the movement of the ink tube 10 along a predetermined trajectory and meeting the requirements of the ink filling device for switching and positioning the ink tube 10.

[0048] In order to realize that when the ink tube 10 moves to the side where the two clamping claws 49 are close to each other, it can change from a horizontal setting to a vertical setting, the following features are specifically set:

[0049] The rotation mechanism 13 further includes a main arc tooth 28, a secondary arc tooth 29, a plurality of tooth seats 22, a plurality of first bevel gears 23, a plurality of second bevel gears 24, a plurality of pipe racks 25 and a plurality of drive gears 27. The tooth seats 22 are fixedly connected to the rotating cylinder 21. The main arc tooth 28 is fixedly connected to one side of the edge of the fixed disk 14 (as Figure 8 shown), the secondary arc tooth 29 is fixedly connected to one side of the center of the fixed disk 14. One ends of the plurality of pipe racks 25 are respectively fixedly connected to the plurality of ink tubes 10. The plurality of first bevel gears 23 are respectively rotatably connected to the plurality of tooth seats 22. The first bevel gear 23 is fixedly connected to the pipe rack 25 coaxially. The plurality of second bevel gears 24 are respectively rotatably connected to the plurality of tooth seats 22. The second bevel gear 24 meshes with the first bevel gear 23. The plurality of drive gears 27 are respectively rotatably connected to the plurality of tooth seats 22. The drive gear 27 is fixedly connected to the second bevel gear 24 coaxially. The drive gear 27 meshes with the main arc tooth 28 and the secondary arc tooth 29 in sequence when the tooth seat 22 moves. When the ink tube 10 moves with the rotating cylinder 21, the drive gear 27 meshes with the main arc tooth 28 and the secondary arc tooth 29 in sequence. When the drive gear 27 meshes with the main arc tooth 28, the drive gear 27 drives the first bevel gear 23 to rotate through the second bevel gear 24, thereby causing the pipe rack 25 and the ink tube 10 to rotate. At this time, the ink tube 10 changes from a horizontal setting to a vertical setting (as Figure 5 shown), preparing for subsequent cleaning work; when the drive gear 27 meshes with the secondary arc tooth 29, the ink tube 10 changes from a vertical setting to a horizontal setting, preparing for subsequent ink filling work.

[0050] In order to improve the stability of the pipe rack 25, the following features are specifically set:

[0051] A magnetic ring 26 is rotatably mounted on the tooth holder 22. This ring is securely connected to the first bevel gear 23 and magnetically attracted to the tooth holder 22. Due to the magnetic attraction between the ring 26 and the tooth holder 22, when the first bevel gear 23 rotates under power, the magnetic force of the ring 26 suppresses any wobbling of the first bevel gear 23 and the connected tube holder 25. This magnetic attraction ensures that the tube holder 25 maintains a relatively stable position during the movement and rotation of the ink tube 10, preventing the ink tube 10 from colliding with other components due to wobbling. This improves the stability of the ink tube 10 during movement and cleaning, ensures the reliability of the ink refilling mechanism, and extends the service life of the device.

[0052] In order to drive the two claws 49 to approach the ink tube 10 in a vertical state so as to facilitate cleaning of the ink tube 10, the following features are specifically provided:

[0053] The impurity removal mechanism 30 further includes an auxiliary motor 32, a auxiliary gear 33 and two power gears 34. The auxiliary motor 32 is fixedly connected to the middle of the adapter frame 31 (eg, Figure 7 As shown, the auxiliary gear 33 is rotatably connected to the center of the adapter frame 31 and coaxially fixedly connected to the output end of the auxiliary motor 32. Two power gears 34 are rotatably mounted in the center of the adapter frame 31 and mesh with each other. The power gear 34 closest to the auxiliary gear 33 meshes with the auxiliary gear 33, and the two power gears 34 are respectively fixedly connected to two claw seats 35. After the auxiliary motor 32 is started, the auxiliary motor 32 drives the power gears 34 to rotate via the auxiliary gear 33. The rotation of the power gear 34 also drives the other meshed power gear 34 to rotate. The two power gears 34 rotate in opposite directions, that is, the rotation of the power gears 34 drives the two claw seats 35 to move toward each other, thereby causing the two claws 49 to approach the vertical ink tube 10.

[0054] 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 also provided:

[0055] The impurity removal mechanism 30 further includes two connecting frames 36, two secondary motors 37, two screws 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, 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 38 is rotationally connected to the connecting frame 36, and the other end is rotationally connected to the claw seat 35. The output end of the secondary motor 37 is coaxially fixedly connected to the screw 38. The screw sleeve 39 is threadedly connected to the screw 38 and fixedly connected to the sliding frame 41. The sliding frame 41 is slidingly connected to the limit rod 40. When the secondary motor 37 is started, the secondary motor 37 drives the screw sleeve 39 to move via the screw 38, and the screw sleeve 39 drives the sliding frame 41 to move. During the movement of the sliding frame 41, the limit rod 40 limits the position of the sliding frame 41, ensuring that the sliding frame 41 can only move linearly along the direction of the limit 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 precisely 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.

[0056] In order to provide clean water to the water spray pipe 42, the following features are also provided:

[0057] 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, a water tank 44 is securely connected to the adapter frame 31 and communicates with the buffer tube 43 via a hose. When the filter 11 needs to be rinsed, the water tank 44 delivers clean water to the buffer tube 43. As the water spray pipe 42 flushes the ink tubes 10, the buffer tube 43 adapts to the positional changes of the water spray pipe 42 during movement, ensuring a continuous supply of clean water. This provides an adequate water source for efficient cleaning of the ink tubes 10 and ensures that the impurity removal mechanism 30 can successfully complete its cleaning task.

[0058] In order to drive the roller brush 48 to rotate and collect the sediment after cleaning, the following features are also provided:

[0059] The impurity removal mechanism 30 also includes a collection bucket 45, a collection hood 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 coaxially with the roller brush 48. The collection hood 46 is coaxially arranged with the roller brush 48 and fixedly connected to the sliding frame 41. The lower end of the collection hood 46 is connected to the collection bucket 45. When the motor 47 is activated and drives the roller brush 48 to rotate at high speed, the roller brush 48 cleans the ink tube 10 during rotation, brushing off impurities on the inner wall of the ink tube 10 and the filter 11. The collection hood 46 effectively collects the sediment removed by the roller brush 48 during cleaning. The lower end of the collection hood 46 is connected to the collection bucket 45, allowing the sediment to fall smoothly into the collection bucket 45. This design integrates the rotational cleaning of the roller brush 48 with the sediment collection, preventing the sediment from scattering and polluting the working environment. It also facilitates centralized sediment processing and improves the cleaning and maintenance convenience of the equipment.

[0060] A method for operating an ink filling device of a printing press further includes the following operating steps:

[0061] S1: When ink needs to be added, the stirring mechanism 4 in the ink tank 3 is started and stirs the ink in the ink tank 3 (such as Figure 3 As shown), to prevent the ink from having different concentrations due to precipitation of impurities when the ink enters the ink storage tank 2;

[0062] S2: During the ink filling 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, impurities in the ink will adhere to the inner wall of the ink tube 10;

[0063] S3: When the filter holes of the filter screen 11 are clogged, the rotation mechanism 13 is activated and drives the ink tube 10 to move. The uncleaned ink tube 10 moves to the side where the two claws 49 are close to each other. The two claws 49, under the action of the impurity removal mechanism 30, hold the ink tube 10 tightly. 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.

[0064] S4: The cleaned ink tube 10 is dried by the blower 12 when it moves to the side of the blower 12, so as to prepare for the next ink filling.

[0065] The working principle of this device is that when the printer body 1 needs to be refilled with ink, the stirring mechanism 4 in the ink tank 3 is first activated. By continuously stirring the ink in the ink tank 3, the stirring mechanism 4 prevents impurities from settling due to long-term static ink, ensuring that the ink entering the ink storage tank 2 has a uniform concentration, providing a guarantee for high-quality printing.

[0066] Subsequently, the ink flows from the ink filling box 3 to the ink storage box 2 through the ink tube 10. The filter screen 11 at one end of the ink tube 10 close to the ink storage box 2 plays an important role. Its high-precision material and precisely designed mesh holes can effectively intercept various impurities in the ink, such as undissolved pigment agglomerates, tiny particles mixed in during production and transportation, etc., significantly improving the quality of the ink in the ink storage box 2. However, as the ink filling process continues, impurities gradually adhere to the inner wall of the ink tube 10, especially at the position of the filter screen 11. When the filter holes of the filter screen 11 are blocked to a certain extent and affect the normal flow rate of the ink, the rotation mechanism 13 on the fixed plate 14 is activated.

[0067] In the rotation mechanism 13, the main motor 16 drives the rotation of the rotating cylinder 21 through the transmission of the main belt pulley 17, the auxiliary belt pulley 18, the main gear 19 and the main gear ring 20, and then makes the ink tube 10 move along the direction of the center of the fixed plate 14, realizing the switching of the ink tube 10. During the movement of the ink tube 10, the driving gear 27 meshes with the main arc tooth 28 and the secondary arc tooth 29 in sequence, causing the ink tube 10 to rotate self - when moving, adjusting the angle of the ink tube 10.

[0068] When the uncleaned ink tube 10 moves between the two clamping 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 clamping claws 49 clamp the ink tube 10. Then, the secondary motor 37 drives the screw rod 38 to move the sliding frame 41, making the water spray pipe 42 and the rolling brush 48 approach the ink tube 10. The water spray pipe 42 sprays high - pressure water to initially wash the ink tube 10 and the filter screen 11. Subsequently, the rolling brush 48 rotates under the drive of the motor 47, cooperating with the water flow to further clean the inner wall of the ink tube 10 and the filter screen 11. The sediment generated by the cleaning is collected by the aggregate cover 46 and falls into the collection bucket 45 through the lower end of the aggregate cover 46.

[0069] After the cleaning process is completed, the cleaned ink tube 10 moves to the side of the blower 12, and the hot air blown by the blower 12 quickly dries the ink tube 10, preparing for the next ink filling.

[0070] The above embodiments only represent one or several implementation manners of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention should be subject to the appended claims.
