Description

Technical Field

[0001] The present invention relates to the technical field of ink production, and in particular to a viscosity detection device used in ink production. Background Art

[0002] Ink refers to a viscous colloidal fluid composed of resins, pigments, fillers, additives, and solvents. It is mainly used for printing various products such as books and periodicals, packaging and decoration, architectural decoration, and electronic circuit boards. After the ink is prepared, it is usually tested with a viscosity tester to determine whether the ink's fluidity, coating properties, printing effect, and drying speed are qualified.

[0003] Existing viscosity detection devices use various methods to detect ink viscosity. For example, an online ink viscosity detection device with publication number CN115046919A includes a housing, a washer, a dryer, a bidirectional ink conveying mechanism, and a detection probe. The interior of the housing is divided into upper and lower working chambers A and B by a partition. A test vessel is located at the center of the upper portion of the partition, and a three-way joint is installed on the bottom of the partition. A longitudinal drive assembly is provided along the length of the top inner wall of the working chamber. A sliding plate is connected to the lower portion of the longitudinal drive assembly. The washer, dryer, and detection probe are each connected to the lower portion of the sliding plate via a lifting drive assembly.

[0004] When testing ink viscosity, existing viscosity testing devices usually insert a testing probe into the ink and directly test the viscosity through the testing probe. This testing method cannot detect multiple groups of inks and has low testing efficiency. For example, the above-mentioned prior art device places ink in a test vessel and uses a testing probe to detect it. This testing method can only detect the ink once. After the test, the ink needs to be replaced before it can be tested again. The detection efficiency is low. At the same time, the testing probe adopts a static testing method, which causes the relative position of the ink and the testing probe to remain unchanged. Therefore, dynamic viscosity testing cannot be achieved, resulting in low accuracy of the ink viscosity test results and certain limitations.

[0005] Therefore, it is urgent to design a viscosity detection device for ink production to solve the above problems. Summary of the Invention

DETAILED DESCRIPTION

[0046] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0047] Example 1: Reference Figure 1-Figure 2A viscosity detection device for ink production includes a support base plate 2 and a control box 3 provided on a detection host 1. The detection host 1, the support base plate 2 and the control box 3 play an integral supporting role, thereby improving the stability of the viscosity detection process. At the same time, a driving source is provided inside the detection host 1 for driving the effective operation of the viscosity detection device.

[0048] The support base plate 2 and the lower portion of the detection host 1 are both provided with shock-absorbing pads for improving the stability of the viscosity detection process.

[0049] The viscosity detection device also includes:

[0050] The detection unit is provided on the control box 3. The detection unit is provided with a viscosity detector 11 for detecting the concentration. The viscosity detector 11 is a device commonly used in the prior art for detecting the viscosity of liquids, and will not be described in detail here.

[0051] The detection unit is used to adjust the height of the viscosity detector 11 so that the viscosity detector 11 can penetrate into the ink to perform viscosity detection. At the same time, the detection unit can also drive the viscosity detector 11 to rotate during the detection process, thereby changing the operating state between the viscosity detector 11 and the ink, realizing dynamic viscosity detection of the ink, and making it easier to detect the viscosity of the ink.

[0052] The placement unit is arranged on the supporting base plate 2. A plurality of liquid storage cylinders 7 for storing ink are arranged in the placement unit. The placement unit is used to realize the positioning of the plurality of liquid storage cylinders 7 and adjust the positions of the liquid storage cylinders 7 after the detection is completed, so that different liquid storage cylinders 7 can cooperate with the viscosity tester 11, thereby realizing the detection of multiple groups of inks, effectively increasing the number of samples tested, and improving the accuracy of the test results.

[0053] The auxiliary unit operates under the drive of the detection unit, which plays a role in saving energy consumption. After operation, it cooperates with the placement unit to realize the rotation of the liquid storage cylinder 7 to be detected, thereby assisting the rotation of the liquid storage cylinder 7, further improving the fluidity of the ink, and further improving the effect of dynamic detection.

[0054] A control panel 4 is provided on the control box 3, which is used to control the opening and closing and operating status of the detection unit, placement unit and auxiliary unit, to achieve automated high-precision detection, improve detection efficiency, realize intelligent and automated detection, and improve detection accuracy.

[0055] Example 2: Reference Figure 2-Figure 7 The technical solution of this embodiment is different from that of the first embodiment in that the detection unit includes a driving component, a positioning component and a viscosity detector 11. The positioning component is used to install and position the viscosity detector 11, and the driving component is used to drive the viscosity detector 11 to rotate and adjust its height position to realize the detection of ink viscosity.

[0056] The driving assembly includes a hydraulic push rod 6 disposed in the control box 3, a lifting plate 8 is fixedly mounted on the driving end of the hydraulic push rod 6, and a steering motor 13 is disposed on the lifting plate 8;

[0057] The hydraulic push rod 6 is started to drive the lifting plate 8 to adjust its height, which can drive the steering motor 13 on the lifting plate 8 to move up and down.

[0058] In a further embodiment, the positioning assembly includes a positioning sleeve 15 fixedly mounted on the driving end of the steering motor 13, and the positioning sleeve 15 is rotatably connected to the lifting plate 8, and a positioning column 14 is provided on the upper part of the viscosity tester 11 to cooperate with the positioning sleeve 15;

[0059] Two engaging blocks 17 are fixedly mounted on the positioning column 14, and two engaging ring grooves 16 are provided in the positioning sleeve 15 to match the corresponding engaging blocks 17;

[0060] The engaging ring groove 16 is composed of a vertical groove, a transverse ring groove and a positioning groove, and the vertical groove, the transverse ring groove and the positioning groove are interconnected;

[0061] When installing the viscosity tester 11, first engage the positioning column 14 on the upper part of the viscosity tester 11 into the positioning sleeve 15, and during the engagement process, insert the two engaging blocks 17 on the positioning column 14 vertically upward through the corresponding engaging ring grooves 16, and then insert the engaging blocks 17 into the vertical grooves;

[0062] When the engaging block 17 is inserted to the top of the vertical groove, the positioning column 14 is rotated as a whole to drive the engaging block 17 to rotate horizontally in the transverse ring groove. After rotating to the farthest position of the transverse ring groove, the positioning column 14 is pulled down to drive the engaging block 17 to move downward, and then the engaging block 17 is driven to move downward into the positioning groove. At this time, the engaging and positioning of the engaging block 17 is completed (forming a position as shown in the appendix of the specification). Figure 6 As shown in the state), the positioning column 14 and the positioning sleeve 15 are engaged and positioned. At this time, the engagement and installation of the viscosity tester 11 are completed, and the viscosity tester 11 will rise and fall with the lifting and lowering of the positioning sleeve 15 and rotate with the rotation of the positioning sleeve 15.

[0063] During the test, the hydraulic push rod 6 drives the lifting plate 8 to move downward, which will drive the steering motor 13, the positioning sleeve 15 and the viscosity detector 11 to move downward together, so that the viscosity detector 11 moves down into the liquid storage cylinder 7 and penetrates into the ink inside the liquid storage cylinder 7. When the test starts, the steering motor 13 can be started to drive the positioning sleeve 15, the positioning column 14 and the viscosity detector 11 to rotate together, so that the viscosity detector 11 rotates in the ink, and the viscosity detector 11 can be started to start the dynamic viscosity test of the ink.

[0064] Example 3: Refer to 2- Figure 4 、 Figure 8-Figure 9 as well as Figure 14-15 The technical solution of this embodiment is different from that of the second embodiment in that the placement unit includes a steering assembly and a placement assembly. The placement assembly is provided with a plurality of liquid storage cylinders 7 for storing ink. The steering assembly is used to adjust the angular position of the liquid storage cylinders 7 and cooperate with the viscosity tester 11 to realize the diverse detection of ink.

[0065] The steering assembly includes a servo motor 12 fixedly mounted on the supporting base plate 2, a driving roller 24 fixedly mounted on the driving end of the servo motor 12, a one-way bearing 25 provided on the driving roller 24, and the one-way bearing 25 cooperates with the positive rotation of the driving roller 24, and a positioning plate 5 fixedly mounted on the one-way bearing 25;

[0066] When the servo motor 12 is started, it will drive the driving roller 24 to rotate. When the servo motor 12 drives the driving roller 24 to rotate in the forward direction, the forward rotation of the driving roller 24 will drive the one-way bearing 1 25 to rotate. When the one-way bearing 1 25 rotates, it will drive the adjustment and placement disk 5 to rotate together.

[0067] In a further embodiment, the placement assembly includes a plurality of placement boxes 22 fixedly mounted on the positioning placement plate 5, each placement box 22 is fixedly mounted with a positioning plate 34 for placing the liquid storage cylinder 7, and each positioning plate 34 is provided with a plurality of locking elastic blocks 35, and the plurality of locking elastic blocks 35 cooperate to achieve the locking position of the liquid storage cylinder 7;

[0068] When testing the ink, first pour a proper amount of ink into the multiple liquid storage cylinders 7, and then snap the multiple liquid storage cylinders 7 into the corresponding placement boxes 22 in sequence;

[0069] When placing the liquid storage cylinder 7, it is first engaged in the positioning plate 34, and the liquid storage cylinder 7 is moved downward so that its sides and bottom squeeze the multiple locking elastic blocks 35 in the positioning plate 34. Under the locking and resetting action of the locking elastic blocks 35, the liquid storage cylinder 7 can be elastically clamped, thereby completing the automatic fixation of the liquid storage cylinder 7.

[0070] When the ink in the liquid storage cylinder 7 directly below the viscosity tester 11 is tested, the servo motor 12 will start to drive the driving roller 24 to rotate forward, and then drive the adjustment placement plate 5 to rotate forward through the one-way bearing 25, and then drive multiple liquid storage cylinders 7 thereon to rotate, and rotate the tested liquid storage cylinder 7 to the next position, and rotate the next untested liquid storage cylinder 7 to directly below the viscosity tester 11. At this time, the viscosity tester 11 will continue to move down to the next liquid storage cylinder 7 to test the ink again, which can effectively improve the detection efficiency, increase the number of test samples and make the test results more accurate.

[0071] Example 4: Reference Figure 2-Figure 4 as well as Figures 8-14 The technical solution of this embodiment is different from that of the third embodiment in that the auxiliary unit includes a linkage assembly, a driven assembly, and a friction disc 18. The linkage assembly cooperates with the driving assembly to adjust the height of the friction disc 18. The liquid storage cylinder 7 cooperates with the friction disc 18 and rotates under the drive of the driven assembly to adjust the position of the ink during the detection process.

[0072] The linkage component includes a vertical slide groove opened on the detection host 1, and a sliding block 36 is slidably installed in the vertical slide groove, and a linkage plate 19 is fixedly installed on the sliding block 36. The vertical slide groove and the sliding block 36 are used to enable the linkage plate 19 to slide up and down stably on the detection host 1 without any deviation.

[0073] A linkage rod 9 is fixedly installed between the linkage plate 19 and the lifting plate 8, and a trigger mechanism is installed between the linkage plate 19 and the supporting base plate 2. The trigger mechanism includes a built-in groove 10 opened in the supporting base plate 2, and a telescopic support column 28 and a return spring 30 are fixedly installed between the bottom wall of the built-in groove 10 and the linkage plate 19;

[0074] When the linkage plate 19 is in the initial position, the reset spring 30 is in a natural state. At this time, the height of the linkage plate 19 is relatively high. When the hydraulic push rod 6 drives the lifting plate 8 and the viscosity tester 11 to move downward for testing, the lifting plate 8 moves downward and drives the linkage rod 9 to move downward. When the linkage rod 9 moves downward, it drives the linkage plate 19 to move downward as a whole.

[0075] A control button 29 is fixedly installed in the built-in slot 10, and the control button 29 cooperates with the servo motor 12. A touch spring rod 31 that cooperates with the control button 29 is fixedly installed at the bottom of the linkage plate 19. When the linkage plate 19 moves downward, it squeezes the return spring 30 and the telescopic support column 28 at its lower part to cause them to contract, while driving the touch spring rod 31 downward. When the touch spring rod 31 moves downward to contact the control button 29, the touch spring rod 31 continues to move downward, squeezing the control button 29 downward, thereby automatically triggering the control button 29 to start.

[0076] When the control button 29 is activated, the servo motor 12 is automatically started, and the servo motor 12 is started and drives the driving roller 24 to rotate in the opposite direction. When the driving roller 24 rotates in the opposite direction, the one-way bearing 25 will not rotate, that is, at this time, the adjustment placement plate 5 and the liquid storage cylinder 7 thereon will not rotate, and thus will not affect the normal detection of the ink in the liquid storage cylinder 7.

[0077] In a further embodiment, the driven assembly includes a driven roller 21 rotatably mounted on the supporting base plate 2, a second one-way bearing 26 is provided on the driving roller 24, and the second one-way bearing 26 cooperates with the reverse rotation of the driving roller 24, a driving wheel is provided on the second one-way bearing 26, a driven wheel is provided on the driven roller 21, and a transmission belt 20 is provided between the driving wheel and the driven wheel;

[0078] When the driving roller 24 rotates in the opposite direction, it drives the one-way bearing 26 to rotate. When the one-way bearing 26 rotates, it drives the driving wheel thereon to rotate. When the driving wheel rotates, it drives the driven wheel to rotate with the cooperation of the transmission belt 20, and then drives the driven roller 21 to rotate together.

[0079] A positioning mechanism is provided between the linkage plate 19 and the driven roller 21. The positioning mechanism includes a transmission roller 27 rotatably mounted on the linkage plate 19, and a friction disc 18 fixedly mounted on the upper end of the transmission roller 27. A driving gear 33 is fixedly mounted on the driven roller 21, and a transmission gear column 32 that is always meshed with the driving gear 33 is fixedly mounted on the transmission roller 27.

[0080] Attached to the instruction manual Figure 12 With the instruction manual Figure 13 It can be seen that the length of the transmission gear column 32 is much longer than the length of the driving gear 33. At the same time, since the transmission roller 27 is set on the linkage plate 19, when the linkage plate 19 moves downward, it will drive the transmission roller 27 to move downward together. When the transmission roller 27 moves downward, it will drive the transmission gear column 32 thereon to move downward together. Due to the long length of the transmission gear column 32, the transmission gear column 32 will not separate from the driving gear 33 when it moves downward (see the attached manual). Figure 13 The position of the transmission gear column 32 shown is the lowest point of downward movement, at which time the transmission gear column 32 is still not separated from the driving gear 33, that is, no matter what position the transmission gear column 32 is in, the driving gear 33 and the transmission gear column 32 are in a meshing state.

[0081] A friction ring 23 is fixedly sleeved on the outside of each placement box 22, and the friction ring 23 cooperates with the friction disc 18. When the linkage plate 19 moves downward, it drives the transmission roller 27 to move downward together. When the transmission roller 27 moves downward, it drives the friction disc 18 thereon to move downward. When the linkage plate 19 moves downward to the lowest position, the friction disc 18 also moves downward to the lowest position. At this time, the friction disc 18 contacts and squeezes the friction ring 23 on the outside of the placement box 22 at the corresponding position.

[0082] When the driven roller 21 rotates, it drives the driving gear 33 to rotate. When the driving gear 33 rotates, it drives the transmission gear column 32 to rotate. When the transmission gear column 32 rotates, it drives the transmission roller 27 to rotate. The rotation of the transmission roller 27 drives the friction disk 18 to rotate. When the friction disk 18 rotates, it drives the friction ring 23 to rotate slowly under the action of friction force, and then drives the placement box 22 to rotate, realizing the slow reverse rotation of the liquid storage cylinder 7 in the placement box 22.

[0083] The reverse rotation of the liquid storage cylinder 7 can cooperate with the rotating viscosity detector 11 during viscosity testing to adjust the relative position of the ink and the viscosity detector 11, and further adjust the contact position between the ink in the liquid storage cylinder 7 and the viscosity detector 11, thereby further improving the effect of dynamic testing and improving the accuracy of the test results.

[0084] The specific detection principle of the viscosity detection device is as follows: When installing the viscosity detector 11, first, the positioning column 14 on the upper part of the viscosity detector 11 is engaged with the positioning sleeve 15. During the engagement process, the two engaging blocks 17 on the positioning column 14 are respectively inserted vertically upward through the corresponding engaging ring grooves 16, and the engaging blocks 17 are inserted into the vertical grooves;

[0085] When the engaging block 17 is inserted to the top of the vertical groove, the positioning column 14 is rotated as a whole to drive the engaging block 17 to rotate horizontally in the transverse ring groove. After rotating to the farthest position of the transverse ring groove, the positioning column 14 is pulled down to drive the engaging block 17 to move downward, and then the engaging block 17 is driven to move downward into the positioning groove, completing the engaging and positioning of the engaging block 17, thereby achieving the engaging and positioning between the positioning column 14 and the positioning sleeve 15. At this time, the engaging and installation of the viscosity tester 11 is completed;

[0086] When testing the ink, first pour a proper amount of ink into the multiple liquid storage cylinders 7, and then snap the multiple liquid storage cylinders 7 into the corresponding placement boxes 22 in sequence;

[0087] When placing the liquid storage cylinder 7, it is first engaged in the positioning plate 34, and the liquid storage cylinder 7 is moved downward so that its sides and bottom squeeze the multiple locking elastic blocks 35 in the positioning plate 34. Under the locking and resetting action of the locking elastic blocks 35, the liquid storage cylinder 7 can be elastically clamped, thereby completing the automatic fixation of the liquid storage cylinder 7.

[0088] During testing, the hydraulic push rod 6 drives the lifting plate 8 to move downward, which drives the steering motor 13, the positioning sleeve 15 and the viscosity tester 11 to move downward together, so that the viscosity tester 11 moves down into the liquid storage cylinder 7 and penetrates into the ink inside the liquid storage cylinder 7. When testing begins, the steering motor 13 can be started to drive the positioning sleeve 15, the positioning column 14 and the viscosity tester 11 to rotate together, so that the viscosity tester 11 rotates in the ink, and the viscosity tester 11 can be started to start the dynamic viscosity test of the ink;

[0089] When the hydraulic push rod 6 drives the lifting plate 8 and the viscosity tester 11 to move downward for testing, the downward movement of the lifting plate 8 will drive the linkage rod 9 to move downward, and when the linkage rod 9 moves downward, it will drive the linkage plate 19 to move downward as a whole, and when the linkage plate 19 moves downward, it will drive the touch spring rod 31 to move downward. When the touch spring rod 31 moves downward and contacts the control button 29, the touch spring rod 31 continues to move downward, squeezing the control button 29 downward, thereby automatically triggering the control button 29 to start;

[0090] When the control button 29 is activated, the servo motor 12 is automatically activated, and the servo motor 12 is activated and drives the driving roller 24 to rotate in the opposite direction. When the driving roller 24 rotates in the opposite direction, it drives the second one-way bearing 26 to rotate. When the second one-way bearing 26 rotates, it drives the driving wheel thereon to rotate. When the driving wheel rotates, it drives the driven wheel to rotate with the cooperation of the transmission belt 20, and then drives the driven roller 21 to rotate together.

[0091] When the driven roller 21 rotates, it drives the driving gear 33 to rotate. When the driving gear 33 rotates, it drives the transmission gear column 32 to rotate. When the transmission gear column 32 rotates, it drives the transmission roller 27 to rotate. The rotation of the transmission roller 27 drives the friction disk 18 to rotate. When the friction disk 18 rotates, it drives the friction ring 23 to rotate slowly under the action of friction force, and then drives the placement box 22 to rotate, realizing the slow reverse rotation of the liquid storage cylinder 7 in the placement box 22.

[0092] The reverse rotation of the liquid storage cylinder 7 can cooperate with the rotating viscosity detector 11 during viscosity testing to adjust the relative position of the ink and the viscosity detector 11, and further adjust the contact position between the ink in the liquid storage cylinder 7 and the viscosity detector 11, thereby further improving the effect of dynamic testing and improving the accuracy of the test results.

[0093] When the ink in the liquid storage cylinder 7 directly below the viscosity tester 11 is tested, the servo motor 12 will start to drive the driving roller 24 to rotate forward, and then drive the adjustment placement plate 5 to rotate forward through the one-way bearing 25, and then drive multiple liquid storage cylinders 7 thereon to rotate, and rotate the tested liquid storage cylinder 7 to the next position, and rotate the next untested liquid storage cylinder 7 to directly below the viscosity tester 11. At this time, the viscosity tester 11 will continue to move down to the next liquid storage cylinder 7 to test the ink again, which can effectively improve the detection efficiency, increase the number of test samples and make the test results more accurate.

[0094] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
