Description

Technical Field

[0001] The invention relates to the field of ink storage, in particular to a storage tank device capable of improving ink discharge uniformity. Background Art

[0002] Ink packaging is the process of packaging the ink in a storage tank into packaging bottles or bags of specified capacity. Since packaging needs to be carried out continuously, the volume of the storage tank is usually very large, which results in a large amount of ink being stored in the storage tank for a long time. After a long time, it is easy to cause some ink raw materials to settle, resulting in uneven content of components in each bottle of ink after packaging, which in turn affects the quality and uniformity of the ink after packaging. The ink raw materials accumulated at the bottom after sedimentation will also clog the packaging head, affecting the smooth progress of ink packaging. The existing solution is usually to set a stirring device in the storage tank to keep the ink in a continuous flow state to prevent the sedimentation of the ink raw materials. However, continuous stirring will affect the stability of the components in the ink and easily generate a large number of bubbles, resulting in the ink being not full in the packaging bottles or bags, and the product properties being unstable, which affects the quality of the ink after packaging.

Both the main liquid inlet hole and the secondary liquid inlet hole are provided with filter screens. A block for closing the secondary liquid inlet hole is provided on the floating plate. A liquid outlet pump is provided on the top of the outer side of the tank body. The liquid outlet pipe is connected with the liquid outlet pump. A sedimentation sensor is provided at a position below the floating plate in the liquid outlet cavity. When the filter screen on the main liquid inlet hole is blocked, the floating plate descends with the liquid level in the liquid outlet cavity to contact the sedimentation sensor. The sedimentation sensor is electrically connected to the power component and the stirring motor.

[0005] Furthermore, the power assembly includes a winding roller and a winding motor that drives the winding roller to rotate, the winding roller is rotatably connected to the inside of the tank body, the pull rope is wound around the winding roller, and the sedimentation sensor is electrically connected to the winding motor.

[0006] Furthermore, a bracket is provided inside the tank body, and a rotating shaft is rotatably connected to the bracket. The winding roller is fixed on the rotating shaft. A sliding seat and a telescopic rod driving the sliding seat to slide laterally are provided inside the tank body. The sedimentation sensor is electrically connected to the winding motor and the telescopic rod.

[0010] Furthermore, the filter screen on the secondary liquid inlet hole is a cylindrical structure, and filter holes are provided on the top and sides of the cylindrical structure.

[0011] Furthermore, a through hole is provided on the top of the tank body, and the liquid outlet pipe is connected to the liquid outlet pump after passing through the through hole. A roller is symmetrically rotatably connected in the through hole, and the roller is in rolling contact with the liquid outlet pipe.

[0012] Furthermore, a partition net is provided in the tank body for separating the liquid outlet pipe from the stirring shaft.

[0013] Furthermore, the liquid outlet seat is connected to a position on the side of the floating wing close to the bottom.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. The structure of the present invention is to arrange a liquid outlet seat in the tank body. The ink in the tank body is discharged through the liquid outlet seat and the liquid outlet pipe on the liquid outlet seat under the action of the liquid outlet pump, so as to realize the quantitative discharging and packaging of the ink. Since the ink flow rate entering from the main liquid inlet hole per unit time is greater than the ink flow rate discharged from the liquid outlet pipe, the liquid outlet cavity is always in a full state, so that the floating plate in the liquid outlet cavity is at the top of the liquid surface under the action of buoyancy, and the blocking block closes the secondary liquid inlet hole. During the packaging process, the liquid outlet seat is bound to the bottom of the tank body by a drawstring, so that the ink at the bottom of the tank body is discharged first. When the ink settles, the settled ink raw materials will block the filter screen of the main liquid inlet hole on the liquid outlet seat, causing the ink flow rate entering the liquid outlet cavity to be less than the ink flow rate discharged from the liquid outlet pipe, thereby causing the liquid level in the liquid outlet cavity to drop, causing the float plate to drop with the liquid level until it contacts the sedimentation sensor below. The electrical signal emitted by the sedimentation sensor drives the stirring motor to rotate, causing the stirring shaft to drive multiple stirring rods to stir the ink in the tank, thereby causing the settled ink raw materials to dissolve quickly, preventing clogging of the dispensing head, and ensuring the uniformity and quality of the ink dispensing discharge; 2. Floating wings are symmetrically arranged on both sides of the liquid outlet seat, and a secondary liquid inlet hole is also arranged on the liquid outlet seat. A blocking block for closing the secondary liquid inlet hole is arranged on the floating plate. When the liquid level in the liquid outlet cavity drops, the blocking block is separated from the secondary liquid inlet hole, thereby opening the secondary liquid inlet hole. At the same time, when the sedimentation sensor sends an electrical signal, the power component electrically connected to it loosens the pull rope after receiving the electrical signal, so that the liquid outlet seat automatically floats up under the action of the floating wings after losing its restraint, and then floats on the liquid surface in the tank body, so that the ink on the top of the liquid surface that does not contain the sedimentation raw materials can enter the liquid outlet cavity through the secondary liquid inlet hole, so that the ink dispensing and discharging can still be carried out smoothly, ensuring the continuity of the dispensing and discharging. However, since the aperture of the secondary liquid inlet hole is smaller than that of the main liquid inlet hole, the ink in the liquid outlet cavity still cannot be filled, the liquid outlet seat still floats on the liquid surface in the tank body, and the stirring motor continues to operate until the sedimented ink raw materials are fully dissolved and the blocking block is closed. The ink raw materials on the filter screen of the main liquid inlet hole are also dissolved, so that the ink can smoothly pass through the main liquid inlet hole into the liquid outlet cavity, so that the liquid outlet cavity is filled with ink, and the float plate automatically floats up under the action of buoyancy, so that the blockage on the float plate closes the secondary liquid inlet hole, and the float plate is separated from the sedimentation sensor, so that the stirring motor stops stirring, avoiding the instability of ink composition and excessive bubbles caused by long-term stirring, thereby ensuring the stability of the ink being packaged and discharged. At the same time, the power component tightens the pull rope, so that the liquid outlet seat moves downward under the pull of the pull rope until it is bound to the bottom of the tank again. The next time the ink settles again, the sedimentation sensor can still be triggered in time, so that the stirring operation is only performed when the ink settles, thereby ensuring the stability of the ink composition. The ink packaging operation will not stop during the whole process, thereby ensuring the continuity of the ink packaging, and ensuring the quality and uniformity of the ink after packaging.

[0024] The present invention will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms fall within the scope limited by the application equally.

[0025] Reference Figure 1 and Figure 2The present invention discloses a storage tank device for improving the uniformity of ink discharge. The main structure includes a tank body 1. The tank body 1 has a large volume, so that the ink stored therein can be continuously packaged and discharged, thereby realizing the continuous packaging operation of the ink. The interior of the tank body 1 is rotatably connected with a stirring shaft 2 through a bearing. The tank body 1 is provided with a stirring motor 3 for driving the stirring shaft 2 to rotate. The stirring motor 3 can be welded or bolted to the top of the inner side or outer side of the tank body 1. Its output shaft is welded or bolted to a rotating shaft 20 to realize the rotation drive of the stirring shaft 2. A plurality of stirring rods 4 are fixed to the stirring shaft 2 by welding or bolts. The stirring shaft 2 is used to drive the plurality of stirring rods 4 to rotate, thereby realizing the rotation stirring of the ink in the tank body 1, so that the settled ink raw materials are quickly dissolved. The interior of the tank body 1 is vertically slidably connected with a liquid outlet seat 5. Specifically, a vertical guide column is arranged in the tank body 1, and a liquid outlet pipe 12 is vertically slidably connected to the guide column. The two sides of the liquid outlet seat 5 are symmetrically fixed by welding or bolts. There is a floating wing 6, the overall density of the floating wing 6 is less than the density of the ink, and specifically, the floating wing 6 can be made of a low-density material or the floating wing 6 adopts a hollow structure, so that the floating wing 6 and the liquid outlet seat 5 can float on the ink liquid surface under the action of buoyancy, and the inside of the tank body 1 is provided with a drawstring 7 for tying the liquid outlet seat 5 to the bottom of the tank body 1. By tightening the drawstring 7 to pull the liquid outlet seat 5 downward, the buoyancy of the floating wing 6 is overcome, and the liquid outlet seat 5 is tied to the bottom of the tank body 1, so that the tank body 1 can be filled and discharged. 1 The ink at the bottom is discharged first. The tank body 1 is provided with a power component for controlling the tightening or loosening of the drawstring 7. The drawstring 7 is tightened by the power component to bind the liquid outlet seat 5 to the bottom of the tank body 1, or the drawstring 7 is loosened and the liquid outlet seat 5 automatically floats to the surface of the ink under the buoyancy of the floating wing 6. When the drawstring 7 is loosened, the liquid outlet seat 5 floats in the tank body 1 under the action of the floating wing 6. Preferably, the liquid outlet seat 5 is completely immersed in the ink, so that the ink can be discharged more smoothly through the liquid outlet seat 5. A liquid outlet cavity 8 is provided inside the liquid outlet seat 5, and the ink in the tank body 1 first enters the liquid outlet cavity 8. A float plate 9 is vertically slidably connected to the liquid outlet cavity 8, and the overall density of the float plate 9 is also smaller than that of the ink. Under the action of the buoyancy of the ink in the liquid outlet cavity 8, the float plate 9 floats in the liquid outlet cavity 8. A main liquid inlet hole 10, an auxiliary liquid inlet hole 11, and a liquid outlet pipe 12 are connected to the liquid outlet cavity 8. The liquid outlet pipe 12 is connected to the bottom of the liquid outlet cavity 8. Preferably, the liquid outlet pipe 12 is made of a flexible plastic material, so that it can follow the up and down movement of the liquid outlet seat 5 to maintain the continuity of ink discharge during the up and down movement of the liquid outlet seat 5. The aperture of the main liquid inlet hole 10 is larger than the diameter of the liquid outlet pipe 12, so that the ink flow rate entering the liquid outlet cavity 8 per unit time is greater than the ink discharged from the liquid outlet pipe 12. The ink flow out, so that the liquid outlet chamber 8 is always in a full state, and the floating plate 9 in the liquid outlet chamber 8 is always at the top of the liquid outlet chamber 8. The aperture of the secondary liquid inlet hole 11 is smaller than the aperture of the main liquid inlet hole 10, and the aperture of the secondary liquid inlet hole 11 is smaller than or equal to the diameter of the liquid outlet pipe 12, so that the liquid outlet chamber 8 cannot be filled with ink when only the secondary liquid inlet hole 11 is filled with liquid. The main liquid inlet hole 10 and the secondary liquid inlet hole 11 are both provided with a filter screen 13. The setting of the filter screen 13 can be used to filter the raw materials settled in the ink to ensure the quality of the ink packaged into the ink bottle or ink bag. When the ink settles, the ink raw materials will block the filter screen 13. The floating plate 9 is provided with a blocking block 14 for closing the secondary liquid inlet hole 11. The floating plate 9 is at the top of the liquid outlet chamber 8. When the ink is blocked, the block 14 closes the auxiliary liquid inlet hole 11, so that the ink only enters the liquid outlet cavity 8 through the main liquid inlet hole 10. The auxiliary liquid inlet hole 11 is used as a backup liquid inlet after being blocked. A liquid outlet pump 15 is provided on the top of the outer side of the tank body 1. The liquid outlet pipe 12 is connected to the liquid outlet pump 15. The ink in the tank body 1 is pumped out by the liquid outlet pump 15, so as to accurately and quantitatively pack and discharge the liquid. A sedimentation sensor 16 is provided at a position below the float plate 9 in the liquid outlet cavity 8. When the packaging is normal, the float plate 9 is at the top of the liquid outlet cavity 8 and is separated from the sedimentation sensor 16. The liquid outlet seat 5 is located at the bottom of the tank body 1. Once the ink settles, the filter screen 13 on the main liquid inlet hole 10 will be blocked in the first time. When the filter screen 13 on the main liquid inlet hole 10 is blocked, the float plate 9 As the liquid level in the liquid outlet chamber 8 drops to contact with the sedimentation sensor 16, such a setting allows the sedimentation sensor 16 to be triggered immediately when the ink sediments. The sedimentation sensor 16 is electrically connected to the power component and the stirring motor 3. The signal emitted by the sedimentation sensor 16 is transmitted to the stirring motor 3, so that the stirring motor 3 drives the stirring shaft 2 and the stirring rod 4 to stir the ink, so that the raw material components in the ink are quickly dissolved, and the distribution of the ink components at various positions inside the tank body 1 is more balanced, thereby ensuring the uniformity of the ink discharged by the packaging. At the same time, the signal emitted by the sedimentation sensor 16 is also transmitted to the power component, so that the power component loosens the pull rope 7, and the liquid outlet seat 5 automatically floats to the top of the tank body 1 under the action of the floating wing 6.And because the floating plate 9 descends, the block 14 is separated from the auxiliary liquid inlet hole 11 and the auxiliary liquid inlet hole 11 is opened, so the ink without sedimentation components on the top can enter the liquid outlet seat 5 through the auxiliary liquid inlet hole 11 for discharge, ensuring the continuity of ink dispensing and discharge. Since the aperture of the auxiliary liquid inlet hole 11 is not larger than the diameter of the liquid outlet pipe 12, the liquid outlet cavity 8 cannot be filled all the time, so the floating plate 9 maintains contact with the sedimentation sensor 16 until the raw material components in the ink are fully dissolved by stirring, and the ink raw materials on the filter screen 13 of the main liquid inlet hole 10 are also dissolved, and the ink flow rate entering the liquid outlet cavity 8 after the main liquid inlet hole 10 is opened increases , so that the ink fills the liquid outlet cavity 8, and the float plate 9 rises under the action of buoyancy and separates from the sedimentation sensor 16. At this time, the stirring motor 3 stops stirring to avoid the continuous stirring that causes the stability of the ink components to deteriorate, prevents the appearance of excessive bubbles, and ensures the stability of the ink after packaging. At the same time, the power component tightens the pull rope 7, and pulls the liquid outlet seat 5 down again and binds it to the bottom of the tank body 1. When the ink settles next time, the sedimentation sensor 16 can still be triggered in the first time, effectively avoiding the influence of ink sedimentation on the uniformity of the discharge, making the proportion of each component in the ink more balanced, and ensuring the quality and uniformity of the ink after packaging. ,

[0026] Preferably, the power assembly includes a winding roller 17 and a winding motor 18 for driving the winding roller 17 to rotate, the winding roller 17 is connected to the output shaft of the winding motor 18, so that the winding motor 18 drives the winding roller 17 to rotate, the winding roller 17 is rotatably connected to the inside of the tank body 1 through a bearing, the pull rope 7 is wound around the winding roller 17, and the sedimentation sensor 16 is electrically connected to the winding motor 18. Such a structure enables the sedimentation sensor 16 to transmit an electrical signal to the winding motor 18 after being triggered, and the pull rope 7 is wound around the winding roller 17 or loosened from the winding roller 17 through the forward and reverse rotation of the winding motor 18, so that the tightening or loosening control of the pull rope 7 is more convenient and accurate.

[0027] Preferably, refer to Figure 5 and Figure 6The inside of the tank body 1 is fixed with a bracket 19 by welding or bolts, and the bracket 19 plays a supporting role. The bracket 19 is rotatably connected with a rotating shaft 20 through a bearing. The winding roller 17 is fixed to the rotating shaft 20 by welding or bolts. When the rotating shaft 20 rotates, it can drive the winding roller 17 to rotate. The inside of the tank body 1 is provided with a slide 21 and a telescopic rod 22 driving the slide 21 to slide horizontally. When the telescopic rod 22 performs a telescopic movement, it can drive the slide 21 to slide horizontally. The settlement sensor 1 6 is electrically connected to the winding motor 18 and the telescopic rod 22. The winding motor 18 is fixed on the slide 21 by welding or bolts. A plug block 23 is welded or bolted on the output shaft of the winding motor 18. The end of the rotating shaft 20 is provided with a slot 24 movably plugged with the plug block 23. The specific longitudinal sections of the plug block 23 and the slot 24 are polygonal, so that the rotating shaft 20 can keep synchronous rotation with the winding motor 18 after the two are plugged and matched. When the sedimentation sensor 16 is triggered, the telescopic rod 22 contracts after receiving the electrical signal, driving the slide 21 and the winding motor 18 to slide in the direction away from the winding roller 17, so that the plug block 23 on the output shaft of the winding motor 18 is disengaged from the slot 24, and then the pull rope 7 is automatically loosened after the rotating shaft 20 loses the restriction of the winding motor 18, so that the liquid extraction seat 5 can automatically float under the buoyancy of the floating wing 6 after losing the restraint, so that the winding motor 18 does not need to be reversed to realize the loosening operation of the pull rope 7, making the rotation control of the winding motor 18 simpler. The utility model is convenient and convenient. After the floating plate 9 is separated from the sedimentation sensor 16, the telescopic rod 22 drives the slide 21 and the winding motor 18 to slide toward the winding roller 17, so that the plug block 23 is reinserted into the slot 24, so that the winding motor 18 and the rotating shaft 20 become one. The winding motor 18 drives the winding roller 17 to rotate to tighten the pull rope 7, thereby pulling the liquid outlet seat 5 downward until it is bound to the bottom of the tank body 1, which greatly simplifies the control steps of the up and down movement of the liquid outlet seat 5, and improves the accuracy and timeliness of the up and down movement of the liquid outlet seat 5.

[0028] Preferably, a slide groove 25 is provided in the tank body 1. Specifically, a channel steel is fixed in the tank body 1 by welding or bolts, and the groove on the channel steel serves as the slide groove 25. The slide seat 21 is connected in the slide groove 25 along the lateral sliding, providing a guide for the lateral sliding of the slide seat 21, ensuring the accuracy of the lateral sliding of the slide seat 21 and the winding motor 18. A compression spring 26 is provided between the slide seat 21 and the side wall of the slide groove 25. A shift block 27 is fixed at the movable end of the telescopic rod 22 by welding or bolts, and the shift block 27 is in contact with the slide seat 21. When the telescopic rod 22 is retracted, such a structure can use the shift block 27 to pull the slide seat 21 to slide, so that the plug block 23 is smoothly separated from the slot 24. This process The compression spring 26 is compressed, and when the plug block 23 needs to be re-engaged with the slot 24, the telescopic rod 22 is extended, releasing the restriction of the slide block 27 on the slide seat 21. Under the action of the compression spring 26, the slide seat 21 and the winding motor 18 automatically slide toward the rotating shaft 20. At this time, the plug block 23 may not be completely aligned with the slot 24, but the plug block 23 fits the end of the slot 24 under the action of the compression spring 26. When the winding motor 18 rotates, the plug block 23 rotates accordingly until the plug block 23 is aligned with the slot 24. Under the elastic force of the compression spring 26, the plug block 23 on the winding motor 18 is automatically inserted into the slot 24, so that the plug-in cooperation between the plug block 23 and the slot 24 is smoother and more accurate.

[0029] Preferably, refer to Figure 3 The bracket 19 is located on the inner wall of the tank body 1 near the top, so that the bracket 19 and the components thereon will not be immersed in the ink, ensuring the normal operation of each component thereon and avoiding the service life being affected by the erosion of the ink. The bottom of the tank body 1 is rotatably connected to the steering wheel 28 through a bearing, and the pull rope 7 is connected to the liquid outlet seat 5 after passing around the steering wheel 28. With such a structure, the pull rope 7 can pull the liquid outlet seat 5 downward under the action of the steering wheel 28 when tightened upward, so that the liquid outlet seat 5 is smoothly bound to the bottom of the tank body 1, and the accuracy of the control of the up and down movement of the liquid outlet seat 5 is improved while ensuring the normal operation of each component on the bracket 19.

[0030] Preferably, refer to Figure 7 and Figure 8 The filter screen 13 on the main liquid inlet hole 10 is located inside the main liquid inlet hole 10, and the filter screen 13 on the secondary liquid inlet hole 11 is located outside the secondary liquid inlet hole 11. The blocking block 14 is movably connected to the secondary liquid inlet hole 11. Such a structure allows the blocking block 14 to be inserted into the secondary liquid inlet hole 11, so that the closure of the secondary liquid inlet hole 11 is tighter, and after the blocking block 14 is inserted into the secondary liquid inlet hole 11, it will not contact the filter screen 13 outside it, thereby preventing damage to the filter screen 13. The filter screen 13 of the main liquid inlet hole 10 is arranged inside so that it is not easy to contact with the floating plate 9, thereby ensuring the smoothness of the ink entering the liquid outlet cavity 8 from the main liquid inlet hole 10.

[0031] Preferably, the filter screen 13 on the secondary liquid inlet hole 11 is a cylindrical structure, and filter holes are provided on the top and sides of the cylindrical structure. Such a structure makes the filter area on the filter screen 13 larger, and the filter screen 13 is not easy to be blocked, thereby ensuring the smoothness of the ink entering the liquid outlet cavity 8 from the secondary liquid inlet hole 11 and ensuring the continuity of the ink packaging and discharge.

[0032] Preferably, a through hole 29 is provided on the top of the tank body 1, and the liquid outlet pipe 12 is connected to the liquid outlet pump 15 after passing through the through hole 29. A roller 30 is symmetrically connected to the through hole 29 through a bearing, and the roller 30 is in rolling contact with the liquid outlet pipe 12. Such a structure enables the liquid outlet pipe 12 to be in rolling contact with the roller 30 as the liquid outlet seat 5 moves up and down, thereby preventing the liquid outlet pipe 12 from being easily scratched by the side wall of the through hole 29, and at the same time improving the smoothness of the liquid outlet pipe 12 moving up and down with the liquid outlet seat 5, avoiding bending of the liquid outlet pipe 12, and further ensuring the stability of ink packaging and discharge.

[0033] Preferably, refer to Figure 4 The tank body 1 is provided with a partition net 31 for separating the liquid outlet pipe 12 from the stirring shaft 2. The partition net 31 can block the liquid outlet pipe 12 when the liquid outlet seat 5 moves up and down, preventing it from bending toward the stirring shaft 2 and interfering with the stirring rod 4 on the stirring shaft 2, thereby preventing the stirring rod 4 from damaging the liquid outlet pipe 12, thereby ensuring the integrity of the liquid outlet pipe 12 when the liquid outlet pipe 12 moves up and down.

[0034] Preferably, the liquid outlet seat 5 is connected to the side of the floating wing 6 near the bottom. Such a structure allows the liquid outlet seat 5 connected to the side of the floating wing 6 near the bottom to be completely immersed in ink when the floating wing 6 floats on the liquid surface under the action of buoyancy, so that the main liquid inlet hole 10 or the auxiliary liquid inlet hole 11 on the liquid outlet seat 5 can be completely immersed in the ink, thereby ensuring the stability and continuity of the ink discharging from the liquid outlet seat 5.

[0035] Working principle: The structure of the present invention is provided with a liquid outlet seat 5 in the tank body 1. The ink in the tank body 1 is discharged through the liquid outlet seat 5 and the liquid outlet pipe 12 on the liquid outlet seat 5 under the action of the liquid outlet pump 15, so as to realize the quantitative discharging and subpackaging of the ink. Since the ink flow rate entering from the main liquid inlet hole 10 per unit time is greater than the ink flow rate discharged from the liquid outlet pipe 12, the liquid outlet cavity 8 is always in a full state, so that the floating plate 9 in the liquid outlet cavity 8 is at the top of the liquid surface under the action of buoyancy, and the blocking block 14 closes the auxiliary liquid inlet hole 11. During the subpackaging process, the liquid outlet seat 5 is bound to the bottom of the tank body 1 by the drawstring 7, so that the ink at the bottom of the tank body 1 enters first. When the ink settles, the settled ink raw material will block the filter screen 13 of the main liquid inlet hole 10 on the liquid outlet seat 5, causing the ink flow rate entering the liquid outlet cavity 8 to be less than the ink flow rate discharged from the liquid outlet pipe 12, thereby causing the liquid level in the liquid outlet cavity 8 to drop, so that the float plate 9 drops with the liquid level to contact the sedimentation sensor 16 below, and the electrical signal emitted by the sedimentation sensor 16 drives the stirring motor 3 to rotate, so that the stirring shaft 2 drives the multiple stirring rods 4 to stir the ink in the tank body 1, so as to promote the rapid dissolution of the settled ink raw material, prevent the dispensing head from being blocked, and ensure the uniformity and quality of the ink dispensing discharge;Floating wings 6 are symmetrically arranged on both sides of the liquid outlet seat 5, and an auxiliary liquid inlet hole 11 is also arranged on the liquid outlet seat 5. A blocking block 14 for closing the auxiliary liquid inlet hole 11 is arranged on the floating plate 9. When the liquid level in the liquid outlet cavity 8 drops, the blocking block 14 separates from the auxiliary liquid inlet hole 11, thereby opening the auxiliary liquid inlet hole 11. At the same time, when the sedimentation sensor 16 sends an electrical signal, the power component electrically connected to it loosens the pull rope 7 after receiving the electrical signal, so that the liquid outlet seat 5 automatically floats up under the action of the floating wings 6 after losing its restraint, and then The ink floating on the liquid surface in the tank body 1 allows the ink without sedimentation raw materials on the top of the liquid surface to enter the liquid outlet cavity 8 through the auxiliary liquid inlet hole 11, so that the ink dispensing and discharging can still be carried out smoothly, ensuring the continuity of dispensing and discharging. However, since the aperture of the auxiliary liquid inlet hole 11 is smaller than the aperture of the main liquid inlet hole 10, the ink in the liquid outlet cavity 8 cannot be filled, the liquid outlet seat 5 still floats on the liquid surface in the tank body 1, and the stirring motor 3 continues to operate until the sedimentation ink raw materials are fully dissolved. After that, the ink raw material on the filter screen 13 blocking the main liquid inlet hole 10 also dissolves, so that the ink can smoothly pass through the main liquid inlet hole 10 into the liquid outlet cavity 8, so that the liquid outlet cavity 8 is filled with ink, and the floating plate 9 automatically floats up under the action of buoyancy, so that the block 14 on the floating plate 9 closes the secondary liquid inlet hole 11, and the floating plate 9 is separated from the sedimentation sensor 16, so that the stirring motor 3 stops stirring, avoiding the instability of the ink composition and the appearance of excessive bubbles caused by long-term stirring, and ensuring the stability of the ink after dispensing. At the same time, the power component tightens the pull rope 7, so that the liquid outlet seat 5 moves downward under the pull of the pull rope 7 until it is bound to the bottom of the tank body 1 again. When the ink settles again next time, the sedimentation sensor 16 can still be triggered in time, so that the stirring operation is only performed when the ink settles, ensuring the stability of the ink composition, and the ink dispensing operation will not stop during the whole process, ensuring the continuity of the ink dispensing, and ensuring the quality and uniformity of the ink after dispensing. ;
