[0030] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. The same parts are represented by the same reference numerals. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the accompanying drawings, and the words "bottom surface" and "top surface", "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0031] At present, the ink is often wasted due to ink slurry deposition in decorative paper production enterprises, resulting in high economic losses. The existing solution is manual management and stirring, and strictly controlling the purchase quantity of ink. However, this method is still prone to ink being wasted due to unused slurry deposition, which is difficult to meet the needs of enterprises with large printing volumes. Therefore, the present invention designs such an ink slurry storage method, such as Figure 1 As shown, including:

[0032] All the storage barrels 1, the stirring barrels 2 and the storage barrels 3 are divided into regions, and the storage barrels 1, the stirring barrels 2 and the storage barrels 3 are paired, and the ink in each storage barrel 1 is extracted into the corresponding stirring barrel 2, and the amount of ink extracted from each stirring barrel 2 is obtained by flow rate. The amount of ink reflects the liquid level of the ink extracted into the stirring barrel 2 in the stirring barrel 2. A flow meter is set on the pipeline of each storage barrel 1 and the stirring barrel 2, and the flow rate is recorded by the flow meter. Then, the liquid level can be obtained by converting the volume and flow rate of the stirring barrel 2. Correspondingly, the way to obtain the amount of ink can also be to set a weighing meter at the bottom of the stirring barrel 2, obtain the weight by weighing, and then calculate the amount of ink according to the relationship between the weight and the flow rate ratio of the ink, and finally, the liquid level can be obtained by converting the volume and flow rate of the stirring barrel 2;

[0033] Obtain the corresponding number of the storage barrel 1, the number reflects the characteristic data of the ink stored in each storage barrel 1, and obtain the characteristic data of the ink in the storage barrel 1 according to the number, the characteristic data includes the ink category, ink viscosity, ink storage time and ink composition, the ink category reflects water-based ink, UV curing ink or plant ink, etc., the ink viscosity reflects the viscosity of the ink in the storage barrel 1, the ink storage time reflects the placement time of the ink in the storage barrel, and the ink composition reflects the composition ratio of the original pulp, stabilizer, pigment and water in the storage barrel;

[0034] The stirring rate and stirring cycle of the ink are calculated by matching the ink volume and characteristic data. The stirring cycle reflects the stirring interval time of the stirring barrel 2 and the time of each stirring. The stirring rate and stirring cycle of the stirring barrel are obtained by matching and calculating according to the ink volume in the stirring barrel and the type, viscosity, storage time and composition of the ink. The specific matching calculation method is a preset table, and the stirring work is performed through the corresponding data of the table index;

[0035] Each mixing barrel 2 is stirred until the specified time and then transferred to the storage barrel 3. The specified time reflects a certain time of the day. When all mixing barrels 2 in the mixing barrel 2 area are stirring until the working time of the workers the next day, the mixing barrel 2 transfers the ink to the storage barrel 3 for storage, and the workers carry it to the decorative paper printing equipment for use.

[0036] Since the time when the ink is placed in the stirring barrel 2 may vary, in order to avoid the phenomenon of slurry settling during the unstirring period, the present invention first determines the stirring position according to the amount of ink in the stirring barrel, extracts part of the ink at the stirring position, and obtains the viscosity based on the extracted part of the ink analysis. In normal printing, the slurry is dissolved in water, but when the ink is stationary, the ink slurry will sink to form flocs. The flocs generally sink in the middle to the lower part of the ink, and the upper part is water. Therefore, when extracting, it is necessary to first obtain an extraction position, which is a position where flocs are formed faster, that is, the stirring position. When it is detected that the flocs have reached a limit, stirring is required. Therefore, it is most appropriate to extract the ink at the stirring position. The viscosity of the ink slurry of the flocs is greater than the viscosity of the ink after stirring.

[0037] The cycle threshold is obtained by judging the viscosity that is not within the stirring cycle period. A limit threshold is first preset when the ink becomes flocculent. When the limit threshold is exceeded, it means that the ink is about to produce slurry. The time interval between the most recent stirring and the ink viscosity reaching the limit threshold is obtained as the cycle threshold. The specific comparison is to compare the cycle threshold with the stirring cycle period to re-determine the actual stirring cycle. When the cycle threshold is less than the stirring cycle period, the stirring cycle period is updated and replaced with the cycle threshold, and the cycle threshold is used to control stirring in the future. When the viscosity of the ink is analyzed to be equal to the initial viscosity of the ink during the non-stirring cycle period, or is less than the limit threshold of the viscosity, the stirring cycle period continues to be used as the actual stirring cycle.

[0038] Assume: the stirring cycle is 30 minutes, and the time from stopping stirring to the ink viscosity reaching the limit threshold is 27 minutes. This means that after 27 minutes, the ink will settle and cause damage to the ink. That is, it is necessary to start stirring at 27 minutes, and change the 30-minute stirring cycle to a stirring cycle of 27 minutes. If the ink viscosity is detected to be below the limit threshold within 30 minutes of the stirring cycle, it means that the ink has not immediately settled within a stirring cycle, and the 30-minute stirring cycle can continue to be used.

[0039] Since the ink in the mixing barrel 2 needs to be transferred to the storage barrel 3 the next day, and the ink in the pipeline group will adhere and remain, when the storage barrel 1 is input into the mixing barrel 2 for stirring and then transferred out, inks of different specifications and different components are prone to be contaminated. Therefore, it is necessary to clean the pipeline and the mixing barrel 2, and determine the cleaning position according to the amount of ink. The cleaning position reflects the liquid level of the ink in the mixing barrel 2. After the transfer is completed, the mixing barrel 2 is flushed from the cleaning position to the bottom of the mixing barrel. Assuming that the liquid level of the ink in the mixing barrel 2 is two-thirds from the bottom to the top of the mixing barrel 2 when it is still, this position is defined as the cleaning position. During cleaning, the initial cleaning position is two-thirds from the bottom to the top of the mixing barrel 2, and then cleaning is performed toward the bottom of the barrel in sequence.

[0040] Since the ink at the edge of the stirring barrel 2 will be higher than the initial liquid level when the ink is stirred, the inner wall of the stirring barrel 2 will be stained with ink at a position higher than the liquid level when the ink is stationary, that is, the splashing position of the ink in the stirring state is determined by the ink amount, stirring rate and stirring position, and the cleaning position is updated with the splashing position. The splashing position is determined by a table analysis strategy and an estimation strategy. The table analysis strategy includes presetting an analysis table. The analysis table includes several different ink reference amounts, stirring reference rates, stirring reference positions and splashing reference positions. The splashing reference position corresponding to the ink amount, stirring rate and stirring position is indexed in the analysis table as the splashing position. The analysis table is obtained by an initial training model. There is a lot of data in the analysis table, and the corresponding parameter information is obtained by substituting the training model into the data.

[0041] The estimation strategy includes calculating the splashing height value by using the vortex force generated by the agitator 5 during stirring according to the ink amount, stirring rate and stirring position. The agitator 5 is stationary at the center of the stirring barrel 2 for stirring. The vortex generated by the ink in the stirring barrel 2 is regular. The splashing height value can be calculated by force conversion. The splashing position can be obtained by adding the splashing height value to the liquid level height when the ink is stationary. The splashing height can also be calculated by a flow diagram.

[0042] A flushing table is preset, which includes several different viscosity reference values ​​and water pressure reference values. The viscosity is indexed in the flushing table to obtain the water pressure reference value as the flushing water pressure, and flushing is performed with the flushing water pressure. The viscosity reference value is directly proportional to the flushing water pressure. The greater the viscosity, the more firmly the ink adheres to the side wall of the mixing barrel 2, and therefore the greater the flushing water pressure.

[0043] like Figure 2 As shown, an ink slurry storage system includes an ink pairing group taking module 101, which is used to pair a storage barrel 1, a mixing barrel 2 and a storage barrel 3, extract the ink in each storage barrel 1 into the corresponding mixing barrel 2, and obtain the amount of ink extracted from each mixing barrel 2;

[0045] A stirring information processing module 103 is used to calculate the stirring rate and stirring cycle of the ink according to the ink volume and characteristic data matching;

[0046] The control module 104 is used to control the operation of the pipeline components between the material storage barrel 1, the mixing barrel 2 and the material storage barrel 3.

[0047] It also includes a stirring feedback module 105, which is used to determine the stirring position based on the amount of ink, analyze the viscosity of the portion of ink extracted at the stirring position, obtain a cycle threshold by determining the viscosity that is not within the stirring cycle, and compare the cycle threshold with the stirring cycle to re-determine the actual stirring cycle.

[0048] It also includes a mixing drum cleaning module 106, which is used to determine the cleaning position according to the amount of ink, determine the splashing position of the ink in the stirring state through the ink amount, stirring rate and stirring position, and update the cleaning position according to the splashing position.

[0050] like Figure 4 As shown, the stirrer 5 includes a stirring shaft 51 and a driver 52, the stirring shaft 51 includes a shaft, a primary blade 512 and a secondary blade 513, the shaft includes an inner rod 5111 and an outer rod 5112 sleeved outside the inner rod 5111, the inner rod 5111 is slidably connected in the outer rod 5112 (the inner rod 5111 is slidably connected in the slideway of the inner side wall of the slide rod through a slider), the extraction structure 6 includes a viscosity sensor, the viscosity sensor is located at the bottom end of the secondary blade 513, and the cleaning structure 6 includes a viscosity sensor. The structure includes a first slip ring 71 and a second slip ring 72 which are sleeved on the outer rod 5112. The first slip ring 71 includes a hydraulic chamber 711 and a fluid chamber 712. A slide seat 8 is also rotatably sleeved on the outer rod 5112. The slide seat 8 is slidably connected to the hydraulic chamber 711. The slide seat 8 is provided with a hydraulic pipe 7 which is connected to the external hydraulic oil. The side wall of the outer rod 5112 is provided with a plurality of oil holes which are connected to the hydraulic chamber 711. The secondary blade 513 is fixedly sleeved on the bottom of the inner rod 5111.

[0051] The connection relationship between the slide 8 and the first slip ring 71 is as follows: a protruding connecting edge is provided at the bottom of the slide 8, and the connecting edge is annular. A connecting groove matching the connecting edge is provided on the upper surface of the hydraulic cavity 711 of the first slip ring 71. The slide 8 is inserted into the connecting groove through the connecting edge, and a sealing ring is used to achieve sealing between the two.

[0052] The driving principle is as follows: hydraulic oil is filled into the hydraulic chamber 711 through the slide seat 8, and then filled into the outer rod 5112 from the oil outlet hole of the hydraulic chamber 711. The hydraulic oil can push the inner rod 5111 downward, and the rotation of the outer rod 5112 drives the inner rod 5111 to rotate. The inner rod 5111 can be extended and retracted up and down and can be grasped. When it is necessary to adjust the stirring position and extract ink at different heights, the hydraulic oil is used to drive the inner rod 5111 to extend and retract up and down for adjustment.

[0053] The first-stage blade 512 is fixed at the bottom end of the outer rod 5112, the second slip ring 72 is sleeved on the outer rod 5112 above the first-stage blade 512, a plurality of vertical water supply pipes 9 are connected between the first slip ring 71 and the second slip ring 72, a water supply pipe 10 connected with external flushing water is provided on the hydraulic chamber 711 of the first slip ring 71, a plurality of water supply channels connected with the second slide rod are provided on the side wall of the outer rod 5112, a water inlet channel is provided on the upper side wall of the inner rod 5111, a liquid path connected with the water inlet channel is provided in the inner rod 5111, when the inner rod 5111 extends a certain distance outside the outer rod 5112, the water inlet channel of the inner rod 5111 is connected with the water supply channel, a water spray channel 11 is provided on both the first-stage blade 512 and the second-stage blade 513, the liquid path is connected with the water spray channel 11 of the second-stage blade 513, and a liquid supply channel is also provided between the second slip ring 72 and the water spray channel 11 of the first-stage blade 512.

When the water supply pipe 10 fills the cleaning water into the cleaning cavity of the first slip ring 71, the cleaning water enters the second slip ring 72 from the water supply pipe 9, and then passes into the primary blade 512 and the secondary blade 513 respectively from the second slip ring 72, and is sprayed out from the corresponding water spray channel 11. When the hydraulic oil stops driving the inner rod 5111 to extend and retract, the inner rod 5111 and the outer rod 5112 rotate synchronously. Under the rotation of the primary blade 512 and the secondary blade 513, the greater the pressure of the cleaning water sprayed on the inner wall of the mixing barrel 2, the better the cleaning effect. When the hydraulic oil drives the inner rod 5111 to extend downward, the inner rod 5111 and the outer rod 5112 can still rotate synchronously, but the inner rod 5111 can be cleaned from top to bottom in sequence, and the cleaning efficiency is greatly improved.
