Description

TECHNICAL FIELD

[0001] The present application relates to the viscosity detection technical field, especially to a kind of automobile protective wax material viscosity detection method and equipment. BACKGROUND

[0002] Automobile protective wax (also known as car wax or car wax) is a commonly used product to protect car paint and improve gloss. Correct use can effectively prevent damage to car paint from ultraviolet rays, acid rain and dirt.

[0003] During the production of automobile protective wax, its viscosity needs to be determined so that it can be further processed after meeting the viscosity standard. In the prior art, the viscosity of thick liquid is detected by taking a sample cup to take out a specified amount of material, then opening the discharge port and timing. When the material is completely discharged, the timing is stopped. Then, the viscosity of the material is determined according to the flow time and the total amount of the material sample. However, because the material is quite viscous, the material is easily stuck to the inner wall of the sampling cylinder, resulting in material residue, which makes it difficult to control the accuracy of the detection.

[0070] Step seven, the motor 41 drives the gear one 42 to rotate forward to make the L-shaped moving frame 24 up to the top of the reciprocating screw 21, because the feeding cylinder 31 contains liquid, so when up, the scraper 61 and the hollow cylinder 63 and other structures are pushed up, the up distance of the hollow cylinder 63 is the height of the liquid in the feeding cylinder 31, that is, the amount of liquid entering the liquid through the feeding hole 32 in the specified time, according to the time and the amount of material to judge the viscosity of the liquid, then the controller 67 controls the optical camera 68 to acquire the scale pattern 69 on one side of the hollow cylinder 63, the amount of liquid entering the liquid is acquired, and the viscosity of the liquid is calculated;

6. A method for detecting the viscosity of automotive protective wax materials, applicable to the viscosity detection equipment for automotive protective wax materials as described in claim 5, characterized in that, Includes the following steps: Step 1: Start the viscosity detection program through the controller (67). The controller (67) drives the motor (41) to drive the gear one (42) to rotate forward. The forward rotation of the gear one (42) satisfies the direction of rotation of the one-way gear one (22) driving the reciprocating screw (21) to rotate, so that the L-shaped moving frame (24) moves down. The L-shaped moving frame (24) moves down and drives the timing flow acquisition mechanism (3) to move down and insert into the sample tube (7). The liquid in the sample tube (7) surrounds the feed tube (31). The L-shaped moving frame (24) moves to the bottom end of the reciprocating screw (21) and then stops moving. The gear three (311) meshes with the gear two (34). Step 2: After the liquid inside the sample cylinder (7) has calmed down, start the motor (41) to drive gear one (42) to reverse. The reverse rotation of gear one (42) satisfies the direction of rotation of the one-way gear two (310) driving the rotating shaft (39). The rotating shaft (39) drives gear three (311), the bubble elimination mechanism (5) and gear four (312) to rotate. Gear three (311) drives gear two (34) to rotate. The rotation of gear two (34) drives the mounting ring (33) and mounting plate one (35) to rotate. The rotation of mounting plate one (35) drives multiple plugs to rotate. The block (38), spring (36) and mounting plate two (37) move. Because one end of the block (38) is rounded, when the block (38) rotates, the relative force after one end contacts the wall of the feed hole (32) will cause the block (38) to be pulled out. When the block (38) is pulled out, it pushes the mounting plate two (37) to stretch the spring (36). When rotating, the block (38) contacts the outer wall of the feed cylinder (31). After rotating a certain angle, it stops. At this time, the pulled-out block (38) rotates to the side of another row of feed holes (32). Step 3: After the block (38) inside 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 feed holes (32) at different heights. Liquids at different heights have different flow rates due to pressure. Step 4: After the feeding time is reached, the motor (41) drives the gear one (42) to reverse, causing the gear three (311) to drive the gear two (34) to rotate, so that the block (38) is opposite to the feed hole (32) on one side. The spring (36) pulls the mounting plate two (37) to drive the block (38) to insert into the inside of the feed hole (32), sealing the feed hole (32) while pushing the material in the feed hole (32) into the inside of the feed cylinder (31); Step 5: Start the motor (41) to drive gear 1 (42) to rotate forward, so that the L-shaped moving frame (24) 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 inserted into the inside of the feed cylinder (31) to scrape the material on 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 hole 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. If it continues to move upward, the scraper (61) applies pressure to the liquid surface and forces 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). After moving upward to the specified position, the L-shaped moving frame (24) stops moving. Step 6: Start the motor (41) to drive gear 1 (42) to reverse, so that the rotating shaft (39) drives the mounting plate (51) and multiple rubber strips (52) to rotate. The rubber strips (52) rotate and beat the feed cylinder (31). The gas in the liquid in the feed cylinder (31) vibrates and rises upward. It enters the exhaust valve (64) through the air outlet (62) and is then discharged through the air outlet (62) of the hollow cylinder (63). Step 7: The motor (41) drives the gear 1 (42) to rotate forward, causing the L-shaped moving frame (24) to move up to the top of the reciprocating screw (21). Because the feed cylinder (31) contains liquid, it will push the scraper (61) and the hollow cylinder (63) to move up when it moves up. The distance that the hollow cylinder (63) moves up is the height of the liquid in the feed 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 8: The L-shaped moving frame (24) moves up to the end of the screw thread, where gear 2 (34) meshes with gear 4 (312). After obtaining the liquid volume, the motor (41) is started to drive gear 1 (42) to reverse, causing gear 4 (312) to drive mounting plate 1 (35) and block (38) to rotate, reopening the feed hole (32). The scraper (61) applies pressure to the liquid below due to its own weight, causing the liquid to be discharged through the feed hole (32), allowing the material to return to the inside of the sample tube (7), thus completing the detection.
