Description

Technical Field

[0001] The invention relates to the technical field of paint mixing monitoring, and in particular to a mixing monitoring device for paint processing. Background Art

[0002] Before using the paint, the viscosity of the paint needs to be adjusted by adding diluent. The barrels of paint and diluent are drawn into the mixing barrel according to the proportion and fully stirred and blended.

[0003] During the blending process, viscosity testing needs to be carried out in accordance with the standard. The current detection method is to use a Ford cup and a timer. The worker opens the mixing barrel and then uses the Ford cup to scoop up the paint. The scooped paint will flow out from the nozzle at the bottom of the Ford cup, and then the timer is started to obtain the outflow time. If the time meets the standard, the viscosity is qualified. However, the above operation has the following defects: 1. Opening the mixing barrel will cause dust to enter the interior; 2. The Ford cup is located in the air during paint leakage detection, so it will also cause dust adsorption; 3. The paint cannot be monitored manually in real time. Continuing to mix after meeting the standard will result in a waste of time and cost; 4. The paint cannot be evenly scooped when scooping. Summary of the invention

[0054] A controller is fixed on one side of the box body 1 , and the controller is electrically connected to the motor 21 , the electromagnet 540 and the laser detector 520 .

[0055] Working principle:

[0056] The monitoring program is started by the controller, the controller starts the motor 21 to drive the gear 1 22 to rotate, and the gear 1 22 drives the gear 2 35 and the gear 4 42 to rotate;

[0057] The rotation of gear 2 35 drives the rotating shaft 1 34 to rotate, the rotating shaft 1 34 drives the gear 3 36 to rotate, the rotation of gear 3 36 drives the inner gear ring 33 to rotate, the inner gear ring 33 drives the sampling detection mechanism 5 to rotate and move through the telescopic rod 46, the sampling detection mechanism 5 drives the pulley 526 to move inside the annular slide groove 524, the rotation of gear 42 drives the reciprocating screw 1 41 to rotate, the rotation of the reciprocating screw 1 41 causes the threaded sleeve 1 43 to drive the connecting plate 521 to move downward, the connecting plate 521 drives the ring plate 2 527 and the ring plate 3 522 to move downward, the ring plate 3 522 passes through the The pulley 526 drives the sampling and testing mechanism 5 to move downward to pull the inner rod of the telescopic rod 46 out, and the ring plate 2 527 and the ring plate 3 522 drive the sampling and testing mechanism 5 to move downward synchronously so that the tooth block group 1 528 and the tooth block group 2 529 are always located at the same horizontal plane with the gear 6 55, and the tooth block group 3 523 is always located at the same horizontal plane with the gear 5 519, which is convenient for meshing transmission during the rotation process. The rotating structure 3 and the lifting structure 4 operate simultaneously to drive the sampling and testing mechanism 5 to rotate downward, and the materials at multiple positions of the paint in the mixing process are evenly obtained in a step-by-step manner, and the detection result is more accurate;

[0058] The gear 6 55 first meshes with the tooth block group 1 528, and then drives the shaft 2 54 to rotate. The rotation of the shaft 2 54 drives the gear 8 56 to drive the gear 7 58 to rotate. The gear 7 58 drives the sealing plate 510 to rotate through the shaft 3 57, so that the connecting port 2 541 coincides with the feed port. The gear 6 55 is disengaged from the tooth block group 1 528, and the paint enters the interior of the box body 1 through the feed port and falls on the partition 52. After rotating a certain angle, the gear 6 55 is meshed with the tooth block group 2 529. At this time, the top of the partition 52 is already filled with paint. The gear 6 55 is meshed with the tooth block group 2 529 to make the gear 7 58 and the sealing plate 510 rotate, the sealing plate 510 rotates to disengage the feed port from the second connecting port 541, and the feed port is blocked again, while the connecting port 1 59 overlaps with the discharge nozzle 53, and then the gear 6 55 disengages from the gear block group 2 529, and the paint leaks downward through the discharge nozzle 53, the laser detector 520 obtains the time when the paint initially flows out of the discharge nozzle 53, and then performs real-time detection to obtain the time when the paint last flows out of the discharge nozzle 53, and transmits the time data to the controller, which then calculates the total outflow time, and then calculates the blending viscosity of the paint according to the total outflow time;

[0059] The blending material will all leak onto the scraper 511 during the rotation process, and then pass through the discharge port 512 along the slope and fall onto the baffle plate 2 516. When the baffle plate 2 516 is subjected to a certain pressure, it pulls the spring 2 515 and the discharge pipe 513 to create a gap, and the tested paint material enters the bottom of the box body 1. When all the paint material falls on the top of the box body 1, the pressure is less than the pulling force of the spring 1 532, so the baffle plate 1 533 is in a closed state, and then the gear 5 519 is meshed with the gear block group 3 523. The rotation of the gear 5 519 drives the reciprocating screw 2 518 to rotate, so that the threaded sleeve 2 517 drives the moving plate The second baffle 539 moves downward to push the scraper 511 downward. When the material on the top of the second baffle 516 is exhausted, the second baffle 516 closes the discharge pipe 513 and then applies pressure to the paint material below. After the paint material applies pressure to the first baffle 533, the spring 1 532 is pulled to open the discharge pipe 530, and the paint material is sprayed out from the discharge pipe 530. The scraper 511 pushes the material out and then moves upward to reset. When it moves upward to reset, negative pressure is generated at the bottom, and then the air above passes through the second baffle 516 and the discharge pipe 513 and enters the bottom. When the scraper 511 moves downward to push out the paint, negative pressure is generated on the top of the scraper 511 because of the material being pushed out. The negative pressure will make the next When the paint is fed and the paint drips are detected, the flow rate of the paint will increase, which will affect the flow rate of the paint. Therefore, after the negative pressure is generated above the scraper 511, the pressure will pull the piston plate 537 to squeeze the spring three 538 to push the gas inside the cylinder 535 to the inside of the sampling tube 51 through the elbow 534. The controller determines the movement of the piston plate 537 according to the number of rotations of the motor 21, and starts the electromagnet 540 to absorb the moving piston plate 537 after the piston plate 537 moves to a specified distance, thereby solving the problem of negative pressure in the box 1. After the gear five 519 is disengaged from the gear block group three 523, the gear six 519 continues to rotate. 5 meshes with the gear block group 1 528 to carry out a new round of paint mixing, feeding, unloading detection and discharging steps. When the feed port is reopened, the number of rotations of the motor also reaches the number of electromagnet 540 closing, so the electromagnet 540 is synchronously closed, and the spring 3 538 pushes the piston plate 537 to reset. When resetting, negative pressure is generated on the top of the partition plate 52 to suck the external material into the interior of the sampling tube 51. As the material gradually increases, the negative pressure disappears, and the gas replaced by the material is sucked into the cylinder body 535 by the reset piston plate 537 for temporary storage, so as to avoid the gas from being discharged from the feed port and prepare for the next feeding detection gas supply;

[0060] The rotating downward uniform sampling mechanism and the sampling detection mechanism 5 continuously monitor during the paint mixing process. When the viscosity meets the standard, the controller stops mixing and the paint mixing process is completed.

[0061] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
