Description

TECHNICAL FIELD

[0002] In the production process of mixing slurry and coating, the solid content and viscosity of the mixing slurry play a decisive role in the coating quality. The solid content directly affects the thickness, hardness, adhesion and other properties of the coating; the viscosity is related to the uniformity, leveling property of the coating and the fluidity in the coating process. If the solid content of the mixing slurry fluctuates, it will lead to uneven coating thickness, affecting the appearance and performance of the product; abnormal viscosity may cause problems such as foil leakage, bubbles and inconsistent coating thickness during coating, which may even cause the product to be scrapped, increasing production cost.

[0003] At present, the detection of the solid content and viscosity of the mixing slurry in the industry mostly adopts offline manual sampling and inspection method. The on-site operator regularly samples the mixing slurry sample from the main screw or the discharge of the dispersion kettle, and then uses the viscosity detector and the solid content detector for detection. This method has obvious disadvantages. Offline detection requires personnel participation, regular sampling and detection, increasing labor cost, and there are differences in sampling operation and detection operation by different personnel, resulting in low repeatability of detection data of the same batch of materials, and the sample may settle during transportation or storage, resulting in errors in the data.

DETAILED DESCRIPTION

[0018] The embodiments described below with reference to the drawings are exemplary and are used only to explain the present application and cannot be explained as a limitation of the present application.

[0019] Referring to Figures 1-4 As shown in the drawings, the embodiment provides a slurry mixing detection device, which comprises a sampling mechanism 10, a sampling cup 11, a viscosity detection mechanism 20 and a solid content detection mechanism 30, wherein: The sampling mechanism 10 is arranged at a discharge port of a slurry mixing system, and is used for obtaining a slurry sample. The discharge port of the slurry mixing system can be a discharge port of a main screw or a dispersion kettle. Multiple sampling points can also be arranged to increase the coverage rate of sampling inspection and improve the accuracy of data. The sampling cup 11 is arranged below the sampling mechanism 10. The sampling cup 11 can move along a preset path after receiving the slurry sample. The viscosity detection mechanism 20 is arranged on the preset path, and comprises a viscosity detector 21 and a first driving assembly 22. When the sampling cup 11 moves to the viscosity detector 21, the first driving assembly 22 is used to drive the viscosity detector 21 to move up and down relative to the sampling cup 11, so that a rotor 210 on the viscosity detector 21 is immersed in the slurry sample. The solid content detection mechanism 30 is arranged on the preset path, and comprises a solid content detector 31 and a second driving assembly 32. When the sampling cup 11 moves to the solid content detector 31, the second driving assembly 32 is used to obtain the slurry sample and drive it to move to the solid content detector 31. The sampling mechanism 10 is used to automatically obtain the sample. The sampling cup 11 moves along the preset path, and the driving assembly of the detection mechanism is used to complete automatic detection, thereby replacing the steps of manual sampling and operating the detection equipment, and reducing the labor input. In the embodiment, the slurry samples obtained in the same batch pass through different detection mechanisms in sequence on the preset path. The obtained detection data has consistency, and the time for sample submission and waiting for detection is reduced, the sample standing time is reduced, the detection precision is improved, and the detection error is effectively reduced. It should be noted that the slurry mixing detection device is mainly used for detecting viscosity data and solid content data. Of course, other data detection mechanisms can also be added, and the order of the viscosity detection mechanism 20 and the solid content detection mechanism 30 is not limited.

[0020] Referring to Figure 1As shown, in some embodiments of this application, a conveyor belt 12 is provided on a preset path, and a sampling cup 11 is disposed on the conveyor belt 12. The conveyor belt 12 is arranged in a circular loop to drive the sampling cup 11 to move cyclically along the preset path. An identification sensor is provided near each detection mechanism. When the sampling cup 11 is detected to have moved to a preset position, the sampling cup 11 can stop and be detected. After the detection is completed, it continues to move along the preset path. The identification and positioning technologies are based on existing technologies, and those skilled in the art can understand this technical solution based on common knowledge, so it will not be elaborated upon here. In another embodiment, the conveyor belt 12 can also be replaced with a spiral guide rail. Furthermore, the conveyor belt 12 or guide rail is provided with a limiting device, such as a fixed seat with a certain protrusion height. The sampling cup 11 is placed in the fixed seat and is movably connected to the fixed seat. During the movement of the sampling cup 11, the fixed seat is used to prevent the sampling cup 11 from tipping over. When the sampling cup 11 needs to be removed, it can be freely moved out of the fixed seat.

[0021] See Figure 1 As shown, in this embodiment, the sampling mechanism 10 includes a sampling pipeline 100 and a solenoid valve 101. The sampling pipeline 100 is connected to the outlet of the slurry mixing system, and the solenoid valve 101 is used to control the opening and closing of the sampling pipeline 100. The sampling cup 11 is initially placed at the outlet of the sampling pipeline 100. The solenoid valve 101 can be set to open the sampling pipeline 100 at regular intervals and in a quantitative manner, so that the sampling cup 11 can obtain new slurry samples for testing at regular intervals and in a quantitative manner.

[0022] See Figure 2 As shown, in some embodiments of this application, a cleaning component 23 is provided on one side of the viscosity meter 21. The cleaning component 23 includes a first driving member 230 and a wiping part 231. The wiping part 231 is located at the output end of the first driving member 230. After the viscosity meter 21 completes the test, the first driving member 230 drives the wiping part 231 to move to the rotor 210 and clean the slurry sample on the rotor 210. After the rotor 210 of the viscosity meter 21 enters the sampling cup 11 to obtain the slurry sample, there will be residue. If it is not cleaned in time, it may affect the accuracy of the next test. At the same time, in order to improve the automation of this device and reduce manual intervention, the automatic cleaning by the cleaning component 23 can reduce the interference caused by such residue and ensure the accuracy of the test. Of course, the wiping part 231 can be set to be disposable or have a self-cleaning function to ensure the cleaning effect each time the rotor 210 is wiped. In another embodiment, the viscosity meter 21 can also be set to be rotatable so that the rotor 210 can be moved to the cleaning component 23 for cleaning.

[0023] See Figure 3As shown, in this embodiment, the second driving component 32 includes a second driving member 320 and a sampling section 321 disposed at the output end of the second driving member 320. The second driving member 320 drives the sampling section 321 to obtain a pulp sample from the sampling cup 11 and move it to the solids content analyzer 31. The solids content analyzer 31 only needs to add a certain amount of pulp sample during testing. Therefore, the second driving member 320 drives the sampling section 321 to extend into the sampling cup 11 to obtain a portion of the pulp sample, and then moves it to the detection surface of the solids content analyzer 31. The sampling section 321 can be a spoon-shaped structure to ensure that a quantitative amount of pulp sample is obtained each time. When the sampling section 321 moves to the solids content analyzer 31, the second driving member 320 also includes a flipping function to place the pulp sample on the detection surface. The second driving member 320 can use a robotic arm or similar device to perform multiple actions, which are not limited here.

[0024] See Figure 3 As shown, after the slurry sample is tested by the solids content analyzer 31, there will be some residue, which will affect the results of the next test. To solve this technical problem, the solids content detection component in this embodiment also includes a foil feeding position 33 and a third driving component 34. The foil feeding position 33 is located on one side of the solids content analyzer 31, and multiple foils are placed on the foil feeding position 33. The third driving component 34 drives the foils to move onto the solids content analyzer 31. The foils are preferably placed in a stacked manner at the foil feeding position 33, with a maximum of 50 sheets stacked at a time, reducing the number of manual feedings. The foils are placed first, followed by the slurry sample. The foils serve as a support, and after the test is completed, the slurry residue is on the foils, which can prevent contamination of the detection surface of the solids content analyzer 31. In addition, the foils will not burn during the test, making it easy to remove the slurry sample residue along with the foils after the test is completed.

[0025] Further, see Figure 3 As shown, the third driving component 34 includes a third driving element 340 and an adsorption section 341 located at the output end of the third driving element 340. The adsorption section 341 is used to adsorb foil material, and the third driving element 340 drives the adsorption element to move to the solid content analyzer 31. Since the foil material is relatively thin, the adsorption section 341 ensures that only one sheet of foil material is adsorbed at a time, guaranteeing the consistency of the test results. It should be noted that the solid content analyzer 31 is also equipped with a recognition sensor. When the foil material and the paste sample are detected to be placed in the preset position, the solid content analyzer 31 is automatically turned off for testing. After the testing is completed, the solid content analyzer 31 can be automatically turned on.

[0026] See Figure 1 and Figure 3As shown, in this embodiment, a material recovery box 35 is provided on one side of the solid content analyzer 31. After the solid content analyzer 31 completes the test, the third driving member 340 drives the adsorption unit 341 to pick up the foil material located on the solid content analyzer 31 and move it into the material recovery box 35. Preferably, there are two adsorption units 341, which are used to adsorb the foil material before and after the test, respectively, to avoid the adsorption unit 341 being contaminated by the residue of the slurry sample and affecting the test effect.

[0027] See Figure 4 As shown, the detection of this device adopts cyclic automated detection. After completing one cycle of detection, the inner wall of the sampling cup 11 may be adhered with slurry residue. If it is directly used for the next round of sampling, the residue will mix with the new sample, resulting in distortion of subsequent viscosity and solid content detection data. Therefore, in this embodiment, the slurry detection device also includes a cleaning mechanism 40. The cleaning mechanism 40 is located at the rear end of the solid content detection mechanism 30 along a preset path. The cleaning mechanism 40 includes a cleaning component 41 and a fourth driving component 42. The output end of the fourth driving component 42 is provided with a clamping part 43. When the sampling cup 11 moves to the cleaning component 41, the fourth driving component 42 drives the clamping part 43 to clamp the sampling cup 11 and flip the sampling cup 11 to the cleaning component 41. After all tests are completed, the sampling cup 11 moves to the beginning of the preset path to await the next sampling. Before this, the sampling cup 11 is cleaned. The sampling cup 11 is moved to the cleaning component 41 by the conveyor belt 12. No manual transfer is required, and the cleaning action is automatically executed by the fourth drive unit 42. This includes clamping the sampling cup 11, moving it to the cleaning component 41, flipping it over, pouring out the slurry sample, and cleaning it through the cleaning component 41. This reduces manual intervention, achieves automated cleaning, and avoids the safety risks associated with manual cleaning. It should be noted that the fourth drive unit 42 can be executed by multiple execution units, or by a highly automated robotic arm. No limitation is made here.

[0028] See Figure 4 As shown, the cleaning assembly 41 further includes a cleaning tank 410 and a spray head 411. The bottom of the cleaning tank 410 is provided with a waste liquid return tank 412. The spray head 411 is located inside the cleaning tank 410, and a water source flows through the spray head 411. After the tested slurry sample is poured into the cleaning tank 410, it flows to the waste liquid return tank 412. A sensing device is provided at the spray head 411; upon sensing the sampling cup 11, the spray head 411 sprays water onto the sampling cup 11, thoroughly cleaning it. The spray head 411 can be a liquid gun nozzle to increase cleaning pressure and achieve a more thorough cleaning.

[0029] Since the entire process, from sampling to obtaining test results, is conducted offline, the coating die 52 experiences fluctuations or anomalies in coating quality when switching between dispersion tanks during the coating process, due to changes in slurry parameters in different dispersion tanks. On-site personnel then manually adjust parameters such as the coating die gap, flow choke, and pump speed based on observed anomalies. This adjustment method is not only inefficient but also lacks precision, with varying adjustment results among different operators, making it difficult to meet the demands of high-precision coating production.

[0030] In this embodiment, the detection data of the viscosity meter 21 and the solid content meter 31 can be uploaded to the MES system 50 of the coating device in real time, and the MES system 50 and the coating die 51 form a feedback closed loop. Specifically, the signal output terminals of the viscosity meter 21 and the solid content meter 31 are respectively connected to the data input terminal of the MES system 50. The MES system 50 is also connected to the coating die 51. The detection results of viscosity and solid content can be fed back to the MES system 50 in real time as a reference for judging the adjustment of coating parameters, so that the die can be adjusted accordingly based on the real-time parameters. Compared with the method of detection and then relying on manual observation and adjustment, this method can effectively improve coating accuracy and reduce adjustment errors. The MES system 50 is existing technology and is mainly used for real-time control, tracking and optimization of the production process to ensure that the production plan is implemented and the data is transparent and traceable. It can generate clear die adjustment suggestions or instructions based on the collected production data. It should be noted that the working principle of the MES system 50 and the adjustment of the coating die 51 by the MES system 50 based on the detection data are existing technologies in this application. This application does not make any improvements to these aspects and will not elaborate further here.

[0031] Based on the above embodiments, the working principle of the paste detection device of this utility model is as follows: Initially, the sampling cup 11 is located below the sampling pipeline 100. The solenoid valve 101 opens the sampling pipeline 100 at regular intervals and in a quantitative manner to obtain the slurry sample. Under the conveyor belt 12, the sampling cup 11 moves along a preset path. When it moves to the viscosity detection mechanism 20, the first drive component 22 drives the viscosity detector 21 to descend to a preset height so that the rotor 210 is immersed in the sampling cup 11. After obtaining the slurry sample, the viscosity detector 21 rises to leave the sampling cup 11. The cleaning component cleans the rotor 210 and wipes away the residual slurry sample. When the sampling cup 11 moves to the solid content detection mechanism 30, the third driving component 340 moves to the foil feeding position 33. After the adsorption part 341 adsorbs the foil, the third driving component 340 drives it to move to the solid content detector 31. The second driving component 320 drives the sampling part 321 to obtain a quantitative amount of mixed pulp sample from the sampling cup 11 and move it to the foil. After the solid content detector 31 senses the mixed pulp sample and the foil, it automatically closes to perform the detection. After the detection is completed, the solid content detector 31 automatically turns on. The third driving component 340 drives another adsorption part 341 to move to the solid content detector 31. The other adsorption part 341 absorbs the foil and mixed pulp sample residue after the detection. The third driving component 340 drives it to move to the material recovery box 35 for recycling. When the sampling cup 11 moves to the cleaning mechanism 40, the fourth drive unit 42 clamps the sampling cup 11 to the cleaning tank 410 and flips the sampling cup 11 to pour out the slurry sample. The spray head 411 sprays and cleans the sampling cup 11. After cleaning, the fourth drive unit 42 drives the sampling cup 11 back to the conveyor belt 12 and is transported by the conveyor belt 12 to the initial position to wait for the next cycle.

[0032] The data from the completed test is uploaded to the MES system 50 in real time for data storage or feedback to the coating die head 51, and adaptive adjustments are made according to the existing methods, which are not limited here.

[0033] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0034] The above description, based on the embodiments shown in the drawings, details the structure, features, and effects of this utility model. The above description is only a preferred embodiment of this utility model, but the scope of implementation of this utility model is not limited to what is shown in the drawings. Any changes made in accordance with the concept of this utility model, or modifications to equivalent embodiments, that do not exceed the spirit covered by the specification and drawings, shall be within the protection scope of this utility model.
