Description

Technical Field

[0001] This invention belongs to the field of ink blending technology, specifically a smart ink blending and anti-condensation device and method for cigarette box printing. Background Technology

[0002] Ink is mainly composed of pigments, binders, additives, and solvents, and is used in various printing applications such as books, packaging, and architectural decoration. Ink contains main and auxiliary components that are uniformly mixed and repeatedly rolled to form a viscous, colloidal fluid. After ink production, it needs to be stored in ink drums. However, during storage, the ink surface is prone to condensation, forming a skin that affects its later use. Therefore, anti-condensation devices are used during storage to prevent surface condensation.

[0003] Chinese patent CN112705066A discloses a UV ink heating device, including a device body with an ink tank inside and a heating liquid tank outside. A base plate is located at the bottom of the device body, and a motor is located at the top center. A connecting block is located below the motor, and a rotating shaft is located below the connecting block. By adding a motor, rotating shaft, and stirring blades, the UV ink is stirred, ensuring that the ink is fully heated and preventing uneven heating that could lead to solidification. This guarantees a certain level of fluidity, uniformity, and purity for the UV ink. The addition of a detachable heating tube allows the heat to be evenly distributed on the outer wall of the ink tank, preventing heat from being concentrated only at the bottom. This ensures uniform heating of the UV ink in the ink tank, reducing heating time. After heating, the ink flows out through an ink outlet pipe.

[0004] In current technology, ink flows out through the ink outlet tube after heating. However, ink is usually a viscous gel-like fluid. If it is not scraped off, ink will adhere to the inner wall and bottom of the ink tank. Moreover, the heating temperature of the inner wall and bottom of the ink tank is too high, which may cause uneven heating. If a scraper-type scraper is used for scraping, long-term wear may cause debris to fall off, contaminating the ink and eventually no longer contacting the ink tank.

[0005] Therefore, the present invention provides an intelligent ink mixing and anti-condensation device and method for cigarette box printing. Summary of the Invention

[0010] Preferably, the lifting mechanism includes a protective box fixed to the top of the cover plate, a first motor fixed to the top of the protective box, a reciprocating screw fixed to the output shaft of the first motor, and the two ends of the reciprocating screw being rotatably connected to the cover plate and the protective box respectively through bearings; a lifting plate is threaded onto the reciprocating screw, and a second motor is fixed to the bottom of the lifting plate.

[0011] Preferably, two guide rods are fixedly connected between the protective box and the cover plate, and the lifting plate is slidably connected to the two guide rods.

[0012] Preferably, one end of an infusion tube is fixedly connected to the bottom of the ink reservoir, and the other end of the infusion tube is fixedly connected to the top of the ink reservoir. A circulation pump is installed on the infusion tube, and the circulation pump is fixedly connected to the outer wall of the ink reservoir via a mounting plate. A viscosity sensor is provided at the top of the circulation pump, and the viscosity sensor is electrically connected to the second motor and the electric push rod respectively.

[0013] Preferably, a filter cylinder is fixedly connected to the bottom end of the infusion tube, a filter plate is fixedly connected inside the filter cylinder, a rotating shaft is rotatably connected to the filter plate, an impeller is fixedly connected to one end of the rotating shaft near the circulating pump, one end of the rotating shaft passes through the filter plate and is fixedly connected to a scraper, the scraper is in contact with the surface of the filter plate; a discharge bin is fixedly connected to the bottom of the filter cylinder near the scraper, and multiple baffles are fixedly connected to the inner wall of the discharge bin.

[0014] Preferably, multiple fixing blocks are fixedly connected to the side wall of the ink reservoir, and each fixing block is rotatably connected to a fixing tube via a pin. Each fixing tube is rotatably connected to a threaded rod via a bearing. Each threaded rod has a rotating block fixedly connected to its top, and a pressure plate is threadedly connected to each threaded rod. Each pressure plate has two vertical rods fixedly connected to its bottom, and the vertical rods are slidably connected to the fixing tube. Each pressure plate has a groove on its side wall near the cover plate, and the groove fits snugly against the top of the cover plate. The bottom of the cover plate fits tightly against a sealing ring, and the sealing ring is embedded in the top of the ink reservoir.

[0015] Preferably, the ink reservoir has a heating chamber inside, and multiple heating tubes are evenly arranged inside the heating chamber. A temperature sensor is fixedly connected to one of the side scrapers and is electrically connected to the heating tubes; a liquid level sensor is fixedly connected to the other side scraper.

[0016] Preferably, a smart ink mixing and anti-condensation method for cigarette box printing includes the following steps: S1. The ink is fed into the ink storage cylinder through the inlet pipe for mixing. At the same time, the second motor and the heating tube are turned on. The second motor drives the rotating rod to rotate, which drives the stirring paddle to stir the ink. The temperature of the ink in the ink storage cylinder is monitored in real time by the temperature sensor. When the temperature reaches the preset value, the heating tube is controlled to stop heating. S2: During the settling process, the circulation pump is turned on periodically to circulate the ink in the ink reservoir through the infusion tube to prevent the ink from settling at the bottom of the ink reservoir. During the circulation process, the ink is filtered through the filter plate. S3: When the ink is circulated in the conveying pipe, the viscosity of the ink is monitored by a viscosity sensor. If the viscosity reaches the preset value, the second motor is started to drive the rotating rod to rotate, so that the stirring paddle stirs the ink.

The limit plate drives the side scraper to rotate, which is used to scrape the ink on the inner wall of the ink storage cylinder. S5: The ink is discharged from the drain pipe, and the ink level in the ink reservoir is continuously monitored by the liquid level sensor. When the liquid level is too low, new ink is added in time.

[0017] The beneficial effects of this invention are as follows: 1. The present invention discloses an intelligent ink mixing and anti-condensation device and method for cigarette box printing. Through the cooperation of a limiting plate and a rotating plate, when the temperature or viscosity of the ink reaches a set value or ink needs to be discharged, two electric push rods are simultaneously activated. The retraction of the output end of the electric push rod drives the push plate to move towards the rotating rod. The push plate then drives the limiting plate to move towards the rotating rod until the output end of the electric push rod is fully retracted. Then, a second motor is activated, and its output shaft drives the rotating rod to rotate. The rotating rod then drives the rotating plate to rotate. When the rotating plate rotates to one side of the limiting plate, it squeezes and pushes the limiting plate to rotate. The limiting plate then drives the side plate to rotate, which in turn drives the side scraper to rotate. During rotation, the side scraper removes ink from the inner wall of the ink storage cylinder.

[0018] 2. The intelligent ink mixing and anti-condensation device and method for cigarette box printing described in this invention uses a stirring paddle and an arc-shaped scraper. The output shaft of a second motor drives a rotating rod to rotate, which in turn drives the stirring paddle and the arc-shaped scraper to rotate, thus stirring the ink to ensure its fluidity and prevent it from condensing. Simultaneously, stirring during heating facilitates uniform heating of the ink. During operation, a lifting mechanism is activated, causing the rotating rod, stirring paddle, and arc-shaped scraper to reciprocate up and down. This facilitates thorough mixing and uniform blending of the ink, while also preventing the arc-shaped scraper from constantly contacting and wearing down the bottom inner wall of the ink reservoir.

[0019] 3. The intelligent ink mixing and anti-condensation device and method for cigarette box printing described in this invention involves setting up a delivery pipe and a filter cylinder, and periodically activating a circulation pump. The circulation pump delivers ink from the ink storage cylinder through a liquid delivery pipe, filters it, and then recirculates it back into the ink storage cylinder. During the flow, a viscosity sensor monitors the viscosity of the ink. When the viscosity reaches a set value, there is a risk of condensation, requiring timely signal transmission and control of a second motor and electric push rod to activate for scraping. During the circulating delivery of the ink, it passes through a filter plate for filtration. As the ink flows from the filter cylinder to the liquid delivery pipe, the ink flow rate increases, driving the impeller to rotate. The impeller drives the rotating shaft to rotate, which in turn drives the scraper to rotate. The scraper removes impurities from the surface of the filter plate during rotation, preventing blockage.

[0022] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0023] like Figures 1 to 9As shown in the embodiment of the present invention, an intelligent ink mixing and anti-condensation device for cigarette box printing includes an ink storage cylinder 1, with a cover plate 2 installed on the top of the ink storage cylinder 1; a drain pipe 12 is fixedly connected to the bottom end of the ink storage cylinder 1; an inlet pipe 5 is fixedly connected to the top of the cover plate 2; a second motor 26 is installed on the top of the cover plate 2 via a lifting mechanism, and a rotating rod 261 is fixedly connected to the output shaft of the second motor 26, the rotating rod 261 slidingly passing through the cover plate 2; two rotating plates 266 are rotatably connected to the bottom of the cover plate 2 via bearings, and the two rotating plates 266 are slidably sleeved with the rotating rod 261 via limiting sleeves; the ink storage cylinder... Two rotating ring plates 264 are rotatably connected to the inner wall of 1 via bearings; two side scrapers 265 are fixed between the two rotating ring plates 264; a side plate 2651 is fixedly connected to the side wall of each side scraper 265 near the rotating plate 266, an electric push rod 2653 is fixedly connected to the side wall of each side plate 2651, a push plate 2654 is fixedly connected to the output end of each electric push rod 2653, a limit plate 2652 is fixedly connected to the side wall of each push plate 2654, and the limit plates 2652 are slidably connected within the side plate 2651; the horizontal central axis of the limit plate 2652 is at the same height as the horizontal central axis of the rotating plate 266.

[0024] In the prior art, after the ink is heated, it flows out through the drain pipe 12. However, ink is usually a viscous colloidal fluid. If it is not scraped off, ink will adhere to the inner wall and bottom of the ink reservoir 1. Moreover, the heating temperature of the inner wall and bottom of the ink reservoir 1 is too high, which may cause uneven heating. If a scraper-type scraper is used for scraping, long-term wear may cause debris to fall off, contaminating the ink, and eventually no longer contacting the ink reservoir 1.

[0025] The side scraper 265 provided by this invention is used to scrape off the ink on the inner wall of the ink reservoir 1. When the temperature or viscosity of the ink reaches a set value or when ink needs to be discharged, the ink on the inner wall of the ink reservoir 1 needs to be scraped off. By controlling the simultaneous opening of two electric push rods 2653, the retraction of the output end of the electric push rod 2653 drives the push plate 2654 to move towards the rotating rod 261. The push plate 2654 drives the limiting plate 2652 to move towards the rotating rod 261 until the output end of the electric push rod 2653 is fully retracted. Then, the second motor 26 is turned on, and the output shaft of the second motor 26 drives the rotating rod 261 to rotate. The rotating rod 261 drives the rotating plate 266 to rotate. Since the horizontal center axis of the limiting plate 2652 is at the same height as the horizontal center axis of the rotating plate 266, the rotating plate 266 rotates to the position of the limiting plate 2652. When the ink is rotated to one side, the limiting plate 2652 is squeezed and rotated. The limiting plate 2652 drives the side plate 2651 to rotate, which in turn drives the side scraper 265 to rotate. During the rotation, the side scraper 265 scrapes off the ink on the inner wall of the ink reservoir 1. This prevents the ink from being heated unevenly due to the high temperature on the inner wall of the ink reservoir 1, and also prevents the ink from sticking to the inner wall of the ink reservoir 1, which would affect the next mixing. Moreover, the side scraper 265 is driven to rotate on demand, and it does not rotate continuously with the rotation of the rotating rod 261, which significantly reduces the working time of the side scraper 265 and helps to extend its service life. During the service life, it will not cause incomplete scraping due to wear. The temperature or viscosity setting value is within the preset range, which serves as the signal for the side scraper 265 to work.

[0026] like Figure 4 As shown, multiple stirring paddles 262 are fixedly connected to the outer wall of the rotating rod 261, and multiple arc-shaped scrapers 263 are fixedly connected to the bottom of the rotating rod 261. The arc-shaped scrapers 263 have the same curvature as the bottom inner wall of the ink storage cylinder 1.

[0027] The stirring paddle 262 and arc-shaped scraper 263 provided by this invention are used to stir ink. When the second motor 26 is turned on, the output shaft of the second motor 26 drives the rotating rod 261 to rotate, which in turn drives the stirring paddle 262 and arc-shaped scraper 263 to rotate, thus stirring the ink to ensure its fluidity and prevent it from stagnating and solidifying. Stirring during heating also facilitates uniform heating of the ink. When the rotating rod 261 is working, the lifting mechanism is also activated, causing the rotating rod 261, stirring paddle 262, and arc-shaped scraper 263 to move up and down reciprocally. This facilitates thorough stirring and uniform mixing of the ink, and also prevents the arc-shaped scraper 263 from constantly contacting and wearing against the bottom inner wall of the ink storage cylinder 1. When the side scraper 265 is working, the arc-shaped scraper 263 also moves downwards under the action of the lifting mechanism to contact the bottom inner wall of the ink storage cylinder 1, scraping away the ink and separating it from the bottom inner wall.

[0028] like Figure 6 As shown, two limiting grooves 269 are provided on the outer wall of the rotating rod 261, and the two rotating plates 266 are respectively fixed to the limiting sleeve, and the limiting sleeve is slidably connected in the limiting groove 269.

[0029] The limiting groove 269 provided by the present invention is used to keep the limiting sleeve slidably connected in the limiting groove 269 during the up and down movement. The side walls of the rotating plate 266 are all fixed to the limiting sleeve, and the top is rotatably connected to the cover plate 2 through the bearing. Therefore, the rotating plate 266 maintains the same height and rotates with the rotating rod 261, and can cooperate with the limiting plate 2652 to rotate at any time.

[0030] like Figure 3 As shown, the lifting mechanism includes a protective box 21 fixed to the top of the cover plate 2. A first motor 22 is fixed to the top of the protective box 21. A reciprocating screw 23 is fixed to the output shaft of the first motor 22. The two ends of the reciprocating screw 23 are rotatably connected to the cover plate 2 and the protective box 21 respectively through bearings. A lifting plate 24 is threaded onto the reciprocating screw 23. A second motor 26 is fixed to the bottom of the lifting plate 24.

[0031] The lifting mechanism provided by this invention is used to drive the stirring paddle 262 and the arc-shaped scraper 263 to reciprocate up and down. By turning on the first motor 22, the output shaft of the first motor 22 rotates forward and backward, driving the reciprocating screw 23 to rotate forward and backward. The reciprocating screw 23 drives the lifting plate 24 to reciprocate up and down. The lifting plate 24 drives the second motor 26 to reciprocate up and down. The second motor 26 drives the rotating rod 261 to reciprocate up and down. The rotating rod 261 drives the stirring paddle 262 and the arc-shaped scraper 263 to reciprocate up and down. This facilitates the control of the working state of the stirring paddle 262 and the arc-shaped scraper 263 under different temperatures and viscosities, achieving the effect of thorough stirring or scraping.

[0032] like Figure 3 As shown, two guide rods 25 are fixedly connected between the protective box 21 and the cover plate 2, and the lifting plate 24 is slidably connected to the two guide rods 25.

[0033] The guide rod 25 provided by the present invention is used to limit the lifting plate 24 during use. When the lifting plate 24 moves, the lifting plate 24 slides on the guide rod 25, and the guide rod 25 keeps the lifting plate 24 moving axially in the vertical direction.

[0034] like Figure 2 and Figure 7 As shown, the bottom of the ink storage cylinder 1 is connected to one end of the infusion tube 3, and one end of the infusion tube 3 is connected to the top of the ink storage cylinder 1. A circulation pump 31 is installed on the infusion tube 3, and the circulation pump 31 is fixed to the outer wall of the ink storage cylinder 1 through a mounting plate. A viscosity sensor 32 is provided at the top of the circulation pump 31, and the viscosity sensor 32 is electrically connected to the second motor 26 and the electric push rod 2653 respectively.

[0035] The infusion tube 3 and circulation pump 31 provided by this invention are used to maintain the circulation flow of ink. During the ink settling process, in order to prevent local ink deposition, the circulation pump 31 needs to be turned on at regular intervals. The ink in the ink storage cylinder 1 is transported through the infusion tube 3 by the circulation pump 31, filtered, and then circulated back into the ink storage cylinder 1. During the flow, the viscosity of the ink is monitored by the viscosity sensor 32. When the viscosity reaches the set value, there may be a risk of coagulation. It is necessary to send out a signal in time and control the second motor 26 and the electric push rod 2653 to start for scraping.

[0036] like Figure 7 and Figure 8As shown, the bottom end of the infusion tube 3 is connected to and fixedly connected to a filter cylinder 33. A filter plate 34 is fixedly connected inside the filter cylinder 33. A rotating shaft 35 is rotatably connected to the filter plate 34. An impeller 37 is fixedly connected to one end of the rotating shaft 35 near the circulating pump 31. One end of the rotating shaft 35 passes through the filter plate 34 and is fixedly connected to a scraper 36. The scraper 36 is in contact with the surface of the filter plate 34. A discharge bin 38 is connected to and fixedly connected to the bottom of the filter cylinder 33 near the scraper 36. Multiple baffles 39 are fixedly connected to the inner wall of the discharge bin 38.

[0037] The filter plate 34 provided by the present invention is used to filter ink during use. In order to prevent small particulate impurities in the ink, the ink passes through the filter plate 34 during circulation and is filtered by the filter plate 34. During the process of the ink flowing from the filter cylinder 33 to the liquid delivery pipe 3, the ink flow rate increases, driving the impeller 37 to rotate. The impeller 37 drives the rotating shaft 35 to rotate, and the rotating shaft 35 drives the scraper 36 to rotate. When the scraper 36 rotates, it scrapes off the impurities on the surface of the filter plate 34 to prevent blockage. During the static process, the impurities will be deposited in the discharge bin 38. Under the action of the baffle plate 39, the disturbance of the impurities by the scraper 36 is reduced.

[0038] like Figure 1 and Figure 9 As shown, multiple fixing blocks 4 are fixedly connected to the side wall of the ink storage cylinder 1. Each fixing block 4 is rotatably connected to a fixing tube 41 via a pin. Each fixing tube 41 is rotatably connected to a threaded rod 46 via a bearing. Each threaded rod 46 is fixedly connected to a rotating block 45 at its top. Each threaded rod 46 is threadedly connected to a pressure plate 42. Each pressure plate 42 is fixedly connected to two vertical rods 44 at its bottom. Each vertical rod 44 is slidably connected to the fixing tube 41. Each pressure plate 42 has a groove 43 on its side wall near the cover plate 2. Each groove 43 fits snugly against the top of the cover plate 2. The bottom of the cover plate 2 is tightly fitted with a sealing ring 13. The sealing ring 13 is embedded in the top of the ink storage cylinder 1.

[0039] The pressure plate 42 provided by this invention is used to fix the cover plate 2. When fixing is required, the screw block and the fixing tube 41 are rotated upwards. The screw block and the fixing tube 41 rotate around the pin to one side of the cover plate 2. Then, the screw block is rotated clockwise. The screw block drives the threaded rod 46 to rotate. The threaded rod 46 drives the pressure plate 42 to move downwards. When the pressure plate 42 moves, the pressure plate 42 drives the vertical rod 44 to slide on the fixing tube 41. The vertical rod 44 keeps the pressure plate 42 moving vertically downwards until it reaches the top of the groove 43. The cover plate 2 is fixed by fitting the wall against it. Then, the other screw blocks are rotated in sequence to install the cover plate 2, so that the top inner wall of the cover plate 2 fits tightly against the sealing ring 13, thus sealing the ink reservoir 1. When it is necessary to open, the screw blocks are rotated in the opposite direction, which drives the pressure plate 42 to move upward, releasing the fixation of the cover plate 2. At this time, the screw blocks are rotated downward around the pin shaft, which will not hinder the opening of the cover plate 2. Moreover, because it is integrated with the ink reservoir 1 by the fixing block 4, it will not fall off, thus realizing the function of quick opening and closing.

[0040] like Figure 2 As shown, the ink storage cylinder 1 has a heating chamber inside, and multiple heating tubes 11 are evenly arranged inside the heating chamber. A temperature sensor 267 is fixedly connected to one of the side scrapers 265, and the temperature sensor 267 is electrically connected to the heating tube 11. A liquid level sensor 268 is fixedly connected to another side scraper 265.

[0041] The temperature sensor 267 provided by this invention is used to monitor the temperature of the ink in real time. When the temperature is higher than the maximum preset value, the heating tube 11 is stopped. When the temperature is lower than the minimum preset value, the heating tube 11 is turned on to continue heating. At the same time, the second motor 26 is turned on to drive the stirring paddle 262 to rotate. By setting a liquid level sensor 268, the ink level in the ink storage cylinder 1 is continuously monitored. When the liquid level is too low, new ink is added in time.

[0042] like Figure 10 As shown, a smart ink mixing and anti-condensation method for cigarette box printing includes the following steps: S1. The ink is fed into the ink storage cylinder 1 through the liquid inlet pipe 5 for mixing. At the same time, the second motor 26 and the heating tube 11 are turned on. The second motor 26 drives the rotating rod 261 to rotate, which drives the stirring paddle 262 to stir the ink. The temperature of the ink in the ink storage cylinder 1 is monitored in real time by the temperature sensor 267. When the temperature reaches the preset value, the heating tube 11 is controlled to stop heating. S2: During the settling process, the circulation pump 31 is turned on periodically to circulate the ink in the ink storage cylinder 1 through the infusion pipe 3 to prevent the ink in the ink storage cylinder 1 from settling at the bottom. During the circulation process, the ink is filtered through the filter plate 34. S3: When the ink is circulated in the conveying pipe, the viscosity of the ink is monitored by the viscosity sensor 32. If the viscosity reaches the preset value, the second motor 26 is started, which drives the rotating rod 261 to rotate, so that the stirring paddle 262 stirs the ink. S4: When the temperature or viscosity reaches the set value, the electric push rod 2653 and the second motor 26 are activated. The output end of the electric push rod 2653 drives the limit plate 2652 to extend. The output shaft of the second motor 26 drives the rotating plate 266 to rotate. When the rotating plate 266 rotates, it pushes the limit plate 2652 to rotate. The limit plate 2652 drives the side scraper 265 to rotate, which is used to scrape the ink on the inner wall of the ink storage cylinder 1. S5: The ink is discharged from the drain pipe 12 and the ink level in the ink reservoir 1 is continuously monitored by the liquid level sensor 268. When the liquid level is too low, new ink is added in time.

[0043] Working principle: When the temperature or viscosity of the ink reaches a set value, or when ink needs to be discharged, the ink on the inner wall of the ink reservoir 1 needs to be scraped off. By controlling the simultaneous activation of two electric push rods 2653, the retraction of the output end of the electric push rod 2653 drives the push plate 2654 to move towards the rotating rod 261. The push plate 2654 then drives the limiting plate 2652 to move towards the rotating rod 261 until the output end of the electric push rod 2653 is fully retracted. Then, the second motor 26 is activated, and its output shaft drives the rotating rod 261 to rotate. The rotating rod 261 then drives the rotating plate 266 to rotate. Since the horizontal centerline of the limiting plate 2652 is at the same height as the horizontal centerline of the rotating plate 266, the rotating plate 266 rotates to the position of the limiting plate. When one side of 2652 is engaged, it will squeeze and push the limiting plate 2652 to rotate. The limiting plate 2652 drives the side plate 2651 to rotate, and the side plate 2651 drives the side scraper 265 to rotate. During the rotation, the side scraper 265 scrapes off the ink on the inner wall of the ink reservoir 1. This prevents the temperature of the inner wall of the ink reservoir 1 from being too high, which would cause uneven heating between the center and the edge of the ink. It also prevents the ink from sticking to the inner wall of the ink reservoir 1 and affecting the next mixing. Moreover, the side scraper 265 is driven to rotate on demand, and it will not rotate continuously with the rotation of the rotating rod 261. This significantly reduces the working time of the side scraper 265 and helps to extend the service life of the side scraper 265. During the service life, it will not cause incomplete scraping due to wear.

[0044] When the second motor 26 is turned on, the output shaft of the second motor 26 drives the rotating rod 261 to rotate, which in turn drives the stirring paddle 262 and the arc-shaped scraper 263 to rotate, stirring the ink to ensure its fluidity and prevent it from stagnating and solidifying. Stirring during heating also facilitates uniform heating of the ink. Simultaneously, the lifting mechanism is activated while the rotating rod 261 is in operation, causing the rotating rod 261, stirring paddle 262, and arc-shaped scraper 263 to move up and down reciprocally. This facilitates thorough stirring and uniform mixing of the ink, while also preventing the arc-shaped scraper 263 from constantly contacting and wearing against the bottom inner wall of the ink reservoir 1. When the side scraper 265 is in operation, the arc-shaped scraper 263, under the action of the lifting mechanism, moves downwards to contact the bottom inner wall of the ink reservoir 1, scraping away the ink and separating it from the bottom inner wall.

[0045] During the ink settling process, to prevent local ink deposition, the circulation pump 31 needs to be turned on periodically. The circulation pump 31 transports the ink in the ink storage cylinder 1 through the liquid delivery pipe 3. After filtration, the ink is circulated back into the ink storage cylinder 1. During the flow, the viscosity of the ink is monitored by the viscosity sensor 32. When the viscosity reaches the set value, there may be a risk of coagulation. The signal needs to be sent out in time, and the second motor 26 and the electric push rod 2653 are controlled to start for scraping. To prevent small particulate impurities from entering the ink, the ink passes through filter plate 34 during circulation. As the ink flows from filter cylinder 33 to infusion pipe 3, the ink flow rate increases, driving impeller 37 to rotate. Impeller 37 drives rotating shaft 35 to rotate, which in turn drives scraper 36 to rotate. When rotating, scraper 36 scrapes away impurities from the surface of filter plate 34 to prevent clogging. During settling, impurities will deposit in discharge bin 38. Under the action of baffle plate 39, the disturbance of impurities by scraper 36 is reduced.

[0046] When fixing is required, rotate the rotating block and fixing tube 41 upwards. The rotating block and fixing tube 41 rotate around the pin shaft to one side of the cover plate 2. Then rotate the rotating block clockwise. The rotating block drives the threaded rod 46 to rotate. The threaded rod 46 drives the pressure plate 42 to move downwards. When the pressure plate 42 moves, the pressure plate 42 drives the vertical rod 44 to slide on the fixing tube 41. The vertical rod 44 keeps the pressure plate 42 moving vertically downwards until the top inner wall of the groove 43 is in contact with the cover plate 2, fixing the cover plate 2. Then rotate the other rotating blocks in sequence to install the cover plate 2, so that the top inner wall of the cover plate 2 is in close contact with the sealing ring 13, thus sealing the ink storage cylinder 1. When opening is required, rotate the rotating block in the opposite direction. The rotating block drives the pressure plate 42 to move upwards, releasing the fixing of the cover plate 2. At this time, rotating the rotating block downwards around the pin shaft will not hinder the opening of the cover plate 2. And because the fixing block 4 is integrated with the ink storage cylinder 1, it will not fall off, realizing the function of quick opening and closing.
