Description

Technical Field

[0001] The present invention relates to the technical field of viscosity detection, and particularly to a method and device for detecting the viscosity of an automotive protective wax material. Background Art

[0002] Automotive protective wax (also known as car wax) is a commonly used product for protecting car paint and enhancing gloss. Correct use can effectively prevent damage to car paint caused by ultraviolet rays, acid rain, dirt, etc.

[0003] During the production process of automotive protective wax, it is necessary to determine its viscosity and further process it after reaching the viscosity standard. In the prior art, the viscosity of thick liquids is detected by taking a specified amount of material with a sampling cup, then opening the discharge port and timing. When the material has leaked out, the timing is stopped, and then the viscosity of the material is judged based on the flow time of the material and the total amount of the sampled material. However, because the material is relatively viscous, it is easy for the material to stick to the inner wall of the sampling cylinder, resulting in residue of the material. Therefore, it is difficult to control the accuracy of the detection. Summary of the Invention

[0004] The present invention provides a method and device for detecting the viscosity of an automotive protective wax material to solve the above deficiencies in the prior art.

[0012] Preferably, the support mechanism includes a base, an L-shaped support frame is fixed on the top of the base, a placement groove is formed on the top of the base, and a sample cylinder is placed inside the placement groove.

[0013] Preferably, the support mechanism includes a base, an L-shaped support frame is fixed on the top of the base, a placement groove is formed on the top of the base, and a sample cylinder is placed inside the placement groove.

[0014] Preferably, the timing flow acquisition mechanism includes a feed cylinder fixed to the bottom of the L-shaped moving frame. A plurality of rows of feed holes are formed in the cylinder wall of the feed cylinder. One side of each row of feed holes is provided with a first mounting plate. A plug corresponding to each row of feed holes is sleeved inside the first mounting plate. The plug is sleeved inside the feed hole. A plurality of springs are fixed to the side of the first mounting plate away from the feed cylinder. One ends of the plurality of springs are fixed to a second mounting plate. The plurality of plugs are fixed to the side of the second mounting plate close to the first mounting plate;

[0015] The outer wall of the top of the feed cylinder is rotatably connected with a mounting ring. The plurality of first mounting plates are fixed to the bottom of the mounting ring. A first gear is fixed to the outer wall of the mounting ring;

[0016] The top of the base is rotatably connected with a rotating shaft. A one-way second gear is installed outside the rotating shaft. A third gear is fixed to the middle section of the rotating shaft. A fourth gear is fixed to the top end of the rotating shaft.

[0017] Preferably, the driving mechanism includes a motor fixed to the top of the base. The output end of the motor is fixed with a first gear. A one-way first gear is meshed on one side of the first gear. A one-way second gear is meshed on the other side of the first gear.

[0018] Preferably, the bubble elimination mechanism includes a mounting disc fixed to the middle section of the rotating shaft. A plurality of rubber strips are fixed to the outer ring of the mounting disc.

[0019] Preferably, the flow optical reading mechanism includes a hollow cylinder sleeved inside the L-shaped support frame. A limit ring is fixed to the top end of the hollow cylinder. A scale pattern is formed on one side of the hollow cylinder;

[0020] A scraper is fixed to the bottom of the limit ring. An air outlet hole is formed at the center position of the scraper. The air outlet hole is communicated with the hollow cylinder;

[0021] An exhaust valve is installed inside the hollow cylinder.

[0022] Preferably, the flow optical reading mechanism further includes a controller fixed to one side of the L-shaped support frame. An optical camera is fixed to one side of the controller. The optical camera faces the scale pattern.

[0023] A method for detecting the viscosity of an automotive protective wax material, which is applicable to the above-mentioned automotive protective wax material viscosity detection device, includes the following steps:

[0024] Step 1: Start the viscosity detection program through the controller. The controller drives the motor to drive Gear 1 to rotate forward. The forward rotation of Gear 1 meets the rotation direction of the one-way Gear 1 driving the reciprocating screw, causing the L-shaped moving frame to move downward. The downward movement of the L-shaped moving frame drives the timing flow acquisition mechanism to move downward and insert into the interior of the sample cylinder. The liquid in the sample cylinder wraps the feed cylinder. The L-shaped moving frame stops moving after moving to the end of the screw tail at the bottom of the reciprocating screw. Gear 3 meshes with Gear 2.

[0025] Step 2: After waiting for the liquid inside the sample cylinder to calm down, start the motor to drive Gear 1 to rotate in reverse. The reverse rotation of Gear 1 meets the rotation direction of the one-way Gear 2 driving the rotating shaft. The rotating shaft drives Gear 3, the bubble elimination mechanism, and Gear 4 to rotate. Gear 3 drives Gear 2 to rotate. The rotation of Gear 2 drives the mounting ring and Mounting Plate 1 to rotate. The rotation of Mounting Plate 1 drives multiple blocking blocks, springs, and Mounting Plate 2 to move. Since one end of the blocking block is rounded, when the blocking block rotates, the relative force when one end contacts the wall of the feed hole will cause the blocking block to be pulled out. When the blocking block is pulled out, it pushes Mounting Plate 2 to stretch the spring. When rotating, the blocking block contacts the outer wall of the feed cylinder and stops after rotating a certain angle. At this time, the pulled-out blocking block rotates to the side position of another row of feed holes.

[0026] Step 3: After the blocking block in the feed hole is removed, start timing. Liquids at different heights outside the feed cylinder will enter the interior of the feed cylinder through feed holes at different heights. Liquids at different heights have different flow rates due to pressure.

[0027] Step 4: After the feeding time arrives, the motor drives Gear 1 to rotate in reverse, causing Gear 3 to drive Gear 2 to rotate, making the blocking block opposite to one side of the feed hole. The spring pulls Mounting Plate 2 to drive the blocking block to insert into the interior of the feed hole, sealing the feed hole and pushing the material in the feed hole into the interior of the feed cylinder at the same time.

[0028] Step 5: Start the motor to drive Gear 1 to rotate forward, causing the L-shaped moving frame that has moved to the screw tail to drive the timing flow acquisition mechanism and the material inside to move upward. When moving upward, the scraper sleeve enters the interior of the feed cylinder to scrape the inner wall of the feed cylinder. The scraped material is located below the scraper. The gas below the scraper enters the air hole of the hollow cylinder through the exhaust valve and is discharged. As the feed cylinder moves upward, the bottom of the scraper contacts the liquid surface. Continuing to move upward, the scraper presses on the liquid surface, forcing the gas between them out through the air outlet. However, when the liquid enters the air outlet, it will be blocked by the exhaust valve. The L-shaped moving frame stops moving after moving to the specified position.

[0029] Step 6: Start the motor to drive Gear 1 to rotate in reverse, causing the rotating shaft to drive the mounting disc and multiple rubber strips to rotate. The rotating rubber strips pump the feed cylinder. The vibration of the feed cylinder causes the gas in the liquid to rise upward, enter the exhaust valve through the air outlet, and then be discharged through the air outlet of the hollow cylinder.

[0030] Step 7: The motor drives Gear 1 to rotate forward, causing the L-shaped moving frame to move upward to the top thread end of the reciprocating screw. Since there is liquid inside the feed cylinder, when moving upward, it will push the scraper and the hollow cylinder upward. The distance that the hollow cylinder moves upward is the height of the liquid in the feed cylinder. Then, the controller controls the optical camera to obtain the scale pattern on one side of the hollow cylinder, obtain the amount of liquid entering the liquid, and calculate the viscosity of the liquid.

[0031] Step 8: After the L-shaped moving frame moves upward to the thread end, Gear 2 meshes with Gear 4. After obtaining the liquid volume, the motor is started to drive Gear 1 to rotate reversely, causing Gear 4 to drive the mounting plate 1 and the plug to rotate, reopening the feed hole. The gravity of the scraper itself presses on the liquid below, causing the liquid to be discharged through the feed hole, and the material to return to the interior of the sample cylinder to complete the detection.

[0032] Compared with the existing technology, the beneficial effects of the present invention are:

[0033] 1. By installing a timed flow acquisition mechanism, the present invention simultaneously acquires liquids at different heights in the sampling cylinder within a specified time, avoiding the influence of liquid pressure differences at different heights on the material flow during detection, thereby affecting the viscosity result. Moreover, the material in the feed hole and the material to be measured are combined together to avoid residue affecting the detection accuracy.

[0034] 2. By installing a bubble elimination mechanism, the present invention eliminates the bubbles generated during material acquisition, avoiding the increase in liquid height caused by bubbles and improving the detection accuracy.

[0035] 3. By installing a flow optical reading mechanism, the present invention scrapes the material on the inner wall of the feed cylinder and the material to be measured below together for comprehensive detection, avoiding the residue of the material on the cylinder wall from affecting the accuracy of the flow data. Then, the scraper is in close contact with the liquid surface and applies pressure to the liquid surface, making the liquid surface in a horizontally pressured state, avoiding the unevenness of the viscous liquid from affecting the accuracy of the detection data. Then, the distance that the scraper rises is obtained to determine the amount of liquid in the feed cylinder, thereby determining the concentration of the liquid. BRIEF DESCRIPTION OF THE DRAWINGS

[0054] The timing flow acquisition mechanism 3 includes a feed cylinder 31 fixed to the bottom of the L-shaped moving frame 24. A plurality of rows of feed holes 32 are formed in the cylinder wall of the feed cylinder 31. One side of each row of feed holes 32 is provided with a first mounting plate 35. A plug 38 corresponding to each row of feed holes 32 is sleeved inside the first mounting plate 35. The plug 38 is sleeved inside the feed hole 32. A plurality of springs 36 are fixed to the side of the first mounting plate 35 away from the feed cylinder 31. One ends of the plurality of springs 36 are fixed to a second mounting plate 37. The plurality of plugs 38 are fixed to the side of the second mounting plate 37 close to the first mounting plate 35;

[0056] A rotating shaft 39 is rotatably connected to the top of the base 11. A one-way second gear 310 is installed outside the rotating shaft 39. A third gear 311 is fixed to the middle section of the rotating shaft 39. A fourth gear 312 is fixed to the top end of the rotating shaft 39.

[0057] The driving mechanism 4 includes a motor 41 fixed to the top of the base 11. A first gear 42 is fixed to the output end of the motor 41. A one-way first gear 22 is meshed with one side of the first gear 42. The one-way second gear 310 is meshed with the other side of the first gear 42.

[0058] The bubble elimination mechanism 5 includes a mounting disc 51 fixed to the middle section of the rotating shaft 39. A plurality of rubber strips 52 are fixed to the outer ring of the mounting disc 51.

[0059] The flow optical reading mechanism 6 includes a hollow cylinder 63 sleeved inside the L-shaped support frame 12. A limit ring 66 is fixed to the top end of the hollow cylinder 63. A scale pattern 69 is formed on one side of the hollow cylinder 63;

[0060] A scraping plate 61 is fixed to the bottom of the limit ring 66. An air outlet hole 62 is formed at the center position of the scraping plate 61. The air outlet hole 62 is communicated with the hollow cylinder 63;

[0061] An exhaust valve 64 is installed inside the hollow cylinder 63.

[0062] A viscosity detection method for an automotive protective wax material, which is applicable to the above-mentioned viscosity detection device for an automotive protective wax material, includes the following steps:

[0063] Step 1: Start the viscosity detection program through the controller 67. The controller 67 drives the motor 41 to drive the first gear 42 to rotate forward. The forward rotation of the first gear 42 meets the rotation direction of the one-way first gear 22 to drive the reciprocating screw 21 to rotate, causing the L-shaped moving frame 24 to move downward. The downward movement of the L-shaped moving frame 24 drives the timing flow acquisition mechanism 3 to move downward and insert into the interior of the sample cylinder 7. The liquid in the sample cylinder 7 wraps the feed cylinder 31. The L-shaped moving frame 24 stops moving after moving to the bottom thread end of the reciprocating screw 21, and the third gear 311 meshes with the second gear 34.

[0064] Step 2: After the liquid inside the sample cylinder 7 becomes calm, start the motor 41 to drive the first gear 42 to rotate in reverse. The reverse rotation of the first gear 42 meets the rotation direction of the one-way second gear 310 to drive the rotating shaft 39 to rotate. The rotating shaft 39 drives the third gear 311, the bubble elimination mechanism 5, and the fourth gear 312 to rotate. The third gear 311 drives the second gear 34 to rotate. The rotation of the second gear 34 drives the mounting ring 33 and the first mounting plate 35 to rotate. The rotation of the first mounting plate 35 drives a plurality of blocking blocks 38, springs 36, and the second mounting plate 37 to move. Since one end of the blocking block 38 is rounded, when the blocking block 38 rotates, the relative force when one end contacts the wall of the feed hole 32 will cause the blocking block 38 to be pulled out. When the blocking block 38 is pulled out, it pushes the second mounting plate 37 to stretch the spring 36. When rotating, the blocking block 38 contacts the outer wall of the feed cylinder 31 and stops after rotating a certain angle. At this time, the pulled-out blocking block 38 rotates to the side position of another row of feed holes 32.

[0065] Step 3: After the blocking block 38 in the feed hole 32 is removed, start timing. The liquids at different heights outside the feed cylinder 31 will enter the interior of the feed cylinder 31 through the feed holes 32 at different heights. The flow rates of the liquids at different heights are different. By feeding at multiple heights simultaneously, the difference in liquid flow rate caused by the pressure difference is solved.

[0066] Step 4: After the feeding time arrives, the motor 41 drives the first gear 42 to rotate in reverse, causing the third gear 311 to drive the second gear 34 to rotate, making the blocking block 38 opposite to one side of the feed hole 32. The spring 36 pulls the second mounting plate 37 to drive the blocking block 38 to insert into the interior of the feed hole 32, sealing the feed hole 32 and pushing the material in the feed hole 32 into the interior of the feed cylinder 31 at the same time, avoiding residue from affecting the detection data.

[0067] Step 5: Start the motor 41 to drive the first gear 42 to rotate forward, so that the L-shaped moving frame 24 that has moved to the end of the wire drives the timing flow acquisition mechanism 3 and the material inside to move upward. When moving upward, the scraper 61 is sleeved into the inside of the feed cylinder 31 to scrape the inner wall of the feed cylinder 31. The material after scraping is located below the scraper 61. The gas below the scraper 61 enters the air holes of the hollow cylinder 63 through the exhaust valve 64 and then is discharged. As the feed cylinder 31 moves upward, the bottom of the scraper 61 contacts the liquid surface. Continuing to move upward, the scraper 61 presses on the liquid surface to force the gas between them out through the air outlet 62. However, when the liquid enters the air outlet 62, it will be blocked by the exhaust valve 64 to prevent liquid loss. After moving upward to the specified position, the L-shaped moving frame 24 stops moving;

[0068] Step 6: Start the motor 41 to drive the first gear 42 to rotate in reverse, so that the rotating shaft 39 drives the mounting disk 51 and multiple rubber strips 52 to rotate. The rubber strips 52 rotate to pump the feed cylinder 31, and the gas in the vibrating liquid in the feed cylinder 31 rises upward, then enters the exhaust valve 64 through the air outlet 62, and then is discharged through the air outlet 62 of the hollow cylinder 63;

[0069] Through vibration, the bubbles generated when entering the feed cylinder 31 are discharged, so that the scraper 61 always contacts the liquid surface, avoiding the influence of gas on the accuracy of the material flow measurement;

[0070] Step 7: The motor 41 drives the first gear 42 to rotate forward to move the L-shaped moving frame 24 upward to the end of the wire at the top of the reciprocating screw 21. Because the inside of the feed cylinder 31 contains liquid, when moving upward, it will push structures such as the scraper 61 and the hollow cylinder 63 upward. The upward movement distance of the hollow cylinder 63 is the height of the liquid in the feed cylinder 31, that is, the amount of liquid entering through the feed hole 32 within a specified time. The viscosity of the liquid is judged according to the time and the amount of material. Then the controller 67 controls the optical camera 68 to obtain the scale pattern 69 on one side of the hollow cylinder 63, obtain the amount of liquid entering the liquid, and calculate the viscosity of the liquid;

[0071] Step 8: After the L-shaped moving frame 24 moves upward to the end of the wire, the second gear 34 meshes with the fourth gear 312. After obtaining the liquid volume, start the motor 41 to drive the first gear 42 to rotate in reverse, so that the fourth gear 312 drives structures such as the first mounting plate 35 and the plug 38 to rotate, and reopen the feed hole 32. The gravity of the scraper 61 itself presses on the liquid below, so that the liquid is discharged through the feed hole 32, and the material returns to the inside of the sample cylinder 7 to complete the detection.

[0072] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.

The rotation of the first mounting plate 35 drives a plurality of blocking blocks 38, springs 36, and the second mounting plate 37 to move. Since one end of the blocking block 38 is rounded, when the blocking block 38 rotates, the relative force when one end contacts the wall of the feed hole 32 will cause the blocking block 38 to be pulled out. When the blocking block 38 is pulled out, it pushes the second mounting plate 37 to stretch the spring 36. When rotating, the blocking block 38 contacts the outer wall of the feed cylinder 31 and stops after rotating a certain angle. At this time, the pulled-out blocking block 38 rotates to the side position of another row of feed holes 32. Step 3: After the blocking block 38 in the feed hole 32 is removed, start timing. Liquids at different heights outside the feed cylinder 31 will enter the interior of the feed cylinder 31 through the feed holes 32 at different heights. The liquids at different heights have different flow rates due to pressure. Step 4: After the feeding time arrives, the motor 41 drives the first gear 42 to rotate in reverse, causing the third gear 311 to drive the second gear 34 to rotate, making the blocking block 38 opposite to one side of the feed hole 32. The spring 36 pulls the second mounting plate 37 to drive the blocking block 38 to insert into the interior of the feed hole 32, sealing the feed hole 32 and pushing the material in the feed hole 32 into the interior of the feed cylinder 31. Step 5: Start the motor 41 to drive the first gear 42 to rotate forward, causing the L-shaped moving frame 24 that has moved to the thread end to drive the timing flow acquisition mechanism 3 and the material inside to move upward. When moving upward, the scraper 61 is sleeved into the interior of the feed cylinder 31 to scrape the inner wall of the feed cylinder 31. The scraped material is located below the scraper 61. The gas below the scraper 61 enters the air holes of the hollow cylinder 63 through the exhaust valve 64 and is discharged. As the feed cylinder 31 moves upward, the bottom of the scraper 61 contacts the liquid surface. Continuing to move upward, the scraper 61 presses on the liquid surface, forcing the gas between them out through the air outlet hole 62. However, when the liquid enters the interior of the air outlet hole 62, it will be blocked by the exhaust valve 64. The L-shaped moving frame 24 stops moving after moving to the specified position. Step Six: Start the motor 41 to drive the first gear 42 to reverse, so that the rotating shaft 39 drives the mounting plate 51 and multiple rubber strips 52 to rotate. The rotating rubber strips 52 pump the gas in the liquid in the feeding cylinder 31 upward. The gas then enters the exhaust valve 64 through the air outlet hole 62 and is discharged through the air outlet hole 62 of the hollow cylinder 63; Step Seven: The motor 41 drives the first gear 42 to rotate forward, causing the L-shaped moving frame 24 to move upward to the top thread end of the reciprocating screw 21. Since there is liquid inside the feeding cylinder 31, when moving upward, it will push the scraper 61 and the hollow cylinder 63 upward. The upward movement distance of the hollow cylinder 63 is the height of the liquid in the feeding cylinder 31. Then, the controller 67 controls the optical camera 68 to obtain the scale pattern 69 on one side of the hollow cylinder 63, obtain the amount of liquid entering the liquid, and calculate the viscosity of the liquid; Step Eight: After the L-shaped moving frame 24 moves upward to the thread end, the second gear 34 meshes with the fourth gear 312. After obtaining the liquid volume, start the motor 41 to drive the first gear 42 to reverse, so that the fourth gear 312 drives the first mounting plate 35 and the plug 38 to rotate, reopening the feeding hole 32. The gravity of the scraper 61 itself presses on the liquid below, causing the liquid to be discharged through the feeding hole 32, and the material returns to the inside of the sample cylinder 7 to complete the detection.
