Description

Technical Field

[0001] The invention relates to the technical field of viscosity testing, and in particular to a device for testing the viscosity of an art pigment. Background Art

[0002] Art pigments are one of the most important materials in painting, which give the works rich colors and expressiveness. The viscosity test of art pigments is an important part of evaluating the fluidity and performance of pigments. It is crucial to ensure the effect of pigments in painting, printing, coatings and other applications. The viscosity test is designed to measure the flow resistance of pigments under specific conditions, thereby evaluating their fluidity and coating performance. Pigments with high viscosity may be difficult to distribute evenly when applied, while pigments with low viscosity may flow easily, affecting the picture effect.

[0003] At present, the viscosity test of art paint mainly adopts the outflow method. During the test, the paint needs to be poured into a flow cup and the time for the paint to flow out from the specified aperture is recorded. The longer the time, the higher the viscosity. During the viscosity test, multiple measurements are required to obtain the average value of the outflow time. The staff needs to first block the outflow hole of the flow cup with their hands, fill the flow cup with paint, then scrape the liquid surface, and finally release their fingers to allow the paint to flow out of the outflow hole of the flow cup. Use a timing tool to time it, and finally repeat the above steps. The operation steps are cumbersome, and the test results are greatly affected by the staff's operation.

[0039] As attached Figure 2 As shown, the upper part of the circular shell 1 is rotatably connected with a horizontal shaft 35 located between the liquid storage barrel 2 and the turntable 14 and axially left and right, the left end of the horizontal shaft 35 is provided with a driving bevel gear 36, the upper end of the vertical shaft 13 is provided with a driven bevel gear 37 meshing with the driving bevel gear 36, the front end of the circular shell 1 is provided with two upper and lower opposite limiting holes 38, the right end of the horizontal shaft 35 extends out of the circular shell 1 between the two limiting holes 38 and is laterally slidably connected with a sleeve 39, the left end of the sleeve 39 is provided with two upper and lower opposite limiting blocks 40, the limiting blocks 40 can be inserted into the limiting holes 38, and the right end of the horizontal shaft 35 is provided with a stopper located in the sleeve 39 The circular plate 41 and the transverse axis 35 are provided with a third spring 42 located between the circular plate 41 and the left end of the sleeve 39. When the limit block 40 is located in the limit hole 38, the sleeve 39 cannot rotate freely. When the staff pulls the sleeve 39 forward, the two limit blocks 40 move out of the limit hole 38. At this time, the sleeve 39 can drive the transverse axis 35 to rotate, the transverse axis 35 drives the active bevel gear 36 to rotate, the active bevel gear 36 drives the driven bevel gear 37 to rotate, and the driven bevel gear 37 drives the vertical axis 13 to rotate, which is convenient for the staff to operate the rotation of the vertical axis 13, and the limit block 40 can realize automatic limit.

[0040] As attached Figures 1 to 3 As shown, the upper end of the liquid storage barrel 2 extends out of the circular housing 1 and is detachably connected to a rubber plug 43 . The staff only needs to open the rubber plug 43 to add pigment into the liquid storage barrel 2 .

[0041] As attached Figure 3 As shown, a liquid outlet pipe 44 is provided at the lower end of the overflow bucket 16, and a pipe plug 45 is detachably connected to the free end of the liquid outlet pipe 44. When the overflow bucket 16 is located directly above the waste liquid bucket 11, the staff only needs to open the pipe plug 45 to allow the waste liquid in the overflow bucket 16 to flow into the waste liquid bucket 11 through the liquid outlet pipe 44.

[0042] As attached Figure 8 As shown, a plurality of anti-skid pads 46 evenly distributed along the circumferential direction are provided at the bottom of the circular housing 1 to prevent the circular housing 1 from moving during the test.

[0043] When the present invention is in use, the staff places the circular housing 1 on a horizontal table, and the multiple anti-skid pads 46 at the bottom of the circular housing 1 are in contact with the table, which can prevent the circular housing 1 from moving during the test. In the initial state, the circular hole 21 is not connected to the opening at the lower end of the quantitative cup 17, and the overflow bucket 16 and the quantitative cup 17 are both directly below the liquid outlet 3. At this time, the raised plate 27 is in contact with the lower end of the arc plate 26, and the baffle 5 is in a separated state from the liquid outlet 3. The staff first pulls the sleeve 39 to the right, and the left end of the sleeve 39 squeezes the third spring 42 between the circular plate 41 to the right. At the same time, the sleeve 39 drives the two limit blocks 40 to leave the limit hole 38, and then the sleeve 39 is rotated by a certain angle to make the limit block 40 misaligned with the limit hole 38. The sleeve 39 drives the horizontal shaft 35 to rotate a certain angle, the horizontal shaft 35 drives the active bevel gear 36 and the driven bevel gear 37 to rotate a certain angle, the driven bevel gear 37 drives the vertical shaft 13 to rotate a certain angle, the vertical shaft 13 drives the rotating disk 14 to rotate a certain angle, the rotating disk 14 drives the raised plate 27 to rotate a certain angle, the raised plate 27 is separated from the arc plate 26, at this time the slider 6 is acted upon by the first spring 23 and moves downward, the slider 6 slides downward along the two cylindrical rods 22 and drives the two pressure rods 7 to move downward, the two pressure rods 7 jointly drive the rear end of the pressure plate 4 to swing downward, the front end of the pressure plate 4 drives the baffle 5 to swing upward, the baffle 5 gradually completely blocks the liquid outlet 3; The staff removes the rubber stopper 43 to expose the opening at the upper end of the liquid storage barrel 2, and then adds the pigment whose viscosity needs to be tested into the liquid storage barrel 2. Since the baffle 5 blocks the liquid outlet 3, the pigment cannot flow out of the liquid outlet 3. The staff rotates the sleeve 39. When the sleeve 39 rotates, it can drive the turntable 14 to rotate. The turntable 14 drives the overflow barrel 16 and the quantitative cup 17 to rotate. The overflow barrel 16 and the quantitative cup 17 are rotated to the bottom of the liquid outlet 3. The raised plate 27 rotates with the turntable 14 and contacts the arc plate 26. The raised plate 27 The arc plate 26 is driven to move upward, and the arc plate 26 drives the slider 6 to slide upward along the two cylindrical rods 22. The slider 6 presses the two first springs 23 upward, and at the same time, the slider 6 drives the two pressure rods 7 to move upward. The two pressure rods 7 jointly drive the rear end of the pressure plate 4 to swing upward, and the front end of the pressure plate 4 drives the baffle 5 to swing downward. The baffle 5 gradually separates from the liquid outlet 3, and the sleeve 39 is released. The sleeve 39 moves to the left under the action of the third spring 42, and the sleeve 39 drives the two limit blocks 40 to move to the left and insert into the limit hole 38; After losing the shielding of the baffle 5, the pigment in the liquid storage barrel 2 gradually flows out from the liquid outlet 3 and then flows into the quantitative cup 17. Since the circular hole 21 is not connected to the opening at the lower end of the quantitative cup 17, the pigment is stored in the quantitative cup 17. The staff can see the liquid level of the pigment in the quantitative cup 17 through the transparent plate 8 and can understand the volume of the pigment in the quantitative cup 17 in real time. When the pigment fills the quantitative cup 17, the pigment begins to overflow from the quantitative cup 17. The overflowed pigment in the quantitative cup 17 flows into the overflow bucket 16 which directly flows to the outside. The staff After seeing the pigment overflowing, the staff first pulls the sleeve 39 to the right to move the limit block 40 out of the limit hole 38, and then rotates the sleeve 39 half a circle, the sleeve 39 drives the horizontal shaft 35 to rotate half a circle, the horizontal shaft 35 drives the active bevel gear 36 and the driven bevel gear 37 to rotate half a circle, the driven bevel gear 37 drives the vertical shaft 13 and the turntable 14 to rotate half a circle, the raised plate 27 rotates with the turntable 14 and separates from the arc plate 26, the first spring 23 drives the baffle plate 5 to move upward and completely block the liquid outlet 3, and the pigment in the liquid storage barrel 2 stops flowing downward; The turntable 14 drives the overflow bucket 16 and the quantitative cup 17 to rotate to the top of the waste liquid bucket 11. When the quantitative cup 17 rotates with the turntable 14, the upper end surface of the quantitative cup 17 contacts the lower end surface of the scraper 15. The scraper 15 scrapes off the excess pigment, so that the liquid surface of the pigment is flush with the upper end surface of the quantitative cup 17, replacing the manual quantitative operation, reducing the influencing factors, and making the test results more accurate. The sleeve 39 is loosened and the two limit blocks 40 are reinserted into the limit holes 38 under the action of the third spring 42; The overflow bucket 16 drives the connecting plate 30 and the pressure column 31 to rotate, and the end of the pressure column 31 slides along the outer edge of the cam 33. When the overflow bucket 16 rotates to the top of the waste liquid bucket 11, the end of the pressure column 31 contacts the raised end of the cam 33, and the raised end of the cam 33 drives the pressure column 31 to move. The stepped end of the pressure column 31 compacts and squeezes the second spring 34. At the same time, the pressure column 31 drives the two guide columns 32 to move. Since the two guide columns 32 are both located in the spiral groove 29, the guide columns 32 will drive the rotating drum 28 to rotate through the spiral groove 29 when they move. The rotating drum 28 drives the pin 19 and the ball 20 to rotate, and the ball 20 drives the round hole 21 around the pin 19. When the guide column 32 moves to the end of the spiral groove 29, the circular hole 21 is connected to the opening at the lower end of the quantitative cup 17, and the pigment in the quantitative cup 17 flows into the waste liquid bucket 11 through the circular hole 21.
