Description

Technical Field

[0001] This utility model relates to the field of water-based acrylic resin detection technology, and in particular to an automatic titration detection device for water-based acrylic resin. Background Technology

[0002] Currently, water-based acrylic resin coatings are the fastest-growing and most diverse type of pollution-free water-based coatings. Titration is a quantitative analysis method that involves adding a standard solution (titrant) of known concentration to the solution to be tested until the reaction reaches completeness or equivalence point. The content of the analyte is then calculated based on the volume of standard solution consumed. Titration is widely used in the field of chemical analysis and has the advantages of accuracy, speed, and simplicity.

[0003] Chinese utility model patent CN211453514U discloses an automatic titration detection device for water-based acrylic resin. While this prior art can improve the accuracy of titration detection of water-based acrylic resin, the titration process still requires shaking or stirring after the titrant and the water-based acrylic resin solution to be tested are placed in the titration bottle. This is because shaking and stirring ensure thorough mixing of the reactants, making the titration reaction more uniform and rapid, thus accelerating the titration detection efficiency. Currently, shaking or stirring is done manually by the testing personnel. Due to the rapid development of water-based acrylic resin coatings, the number of samples requiring testing is very large, and all of these are manually shaken by the testing personnel. Prolonged shaking can cause wrist pain and potentially lead to tenosynovitis, and wrist fatigue can also reduce testing efficiency. Therefore, it is necessary to design an automatic titration detection device for water-based acrylic resin that can automatically perform shaking and mixing. Utility Model Content

[0004] To address the technical problem that the titrant and the water-based acrylic resin solution to be tested require manual shaking and mixing by the testing personnel, this invention provides an automatic titration testing device for water-based acrylic resin.

[0005] This utility model is achieved using the following technical solution: an automatic titration and detection device for water-based acrylic resin, comprising a detection base, a detection platform mounted on the detection base, a titration bottle for mixing liquids on the detection platform, a burette on one side of the titration bottle, multiple clamping assemblies for fixing the burette on the detection platform, multiple shaking components for shaking the titration bottle on the detection platform, a driving assembly for driving the multiple shaking components to operate inside the detection base, multiple detection slots on the detection platform, each shaking component including a rotatable platform inside the detection slot and a driving gear fixedly mounted on the platform, the driving assembly including a servo motor inside the detection base and a connecting rod fixedly mounted on the driving end of the servo motor, one end of the connecting rod penetrating the detection platform and extending into the adjacent detection slot and fixedly mounted to the bottom of the adjacent platform.

[0006] With the above technical solution, the burette is placed on the shaking component. After the titrant and the sample to be tested are added, the driving component will drive the shaking component to shake, thereby accelerating the mixing of the titrant and the sample. The entire shaking process does not require manual operation by the testing personnel, avoiding the risk of wrist injury caused by prolonged shaking.

[0007] As a further improvement to the above solution, a belt hole is provided between every two adjacent detection slots, and a timing belt is fitted on the multiple drive gears to enable the multiple drive gears to drive synchronously, and each belt hole is adapted to the timing belt.

[0008] Using the above technical solution, the synchronous belt movement will cause all the drive gears to rotate together, thereby causing all the placement platforms to rotate.

[0009] As a further improvement to the above solution, each of the placement platforms has two sliding holes on both sides, each of the placement platforms has a clamping plate on both sides, each of the sliding holes has a sliding rod inside, one end of each sliding rod is fixedly installed to the adjacent clamping plate, and a rubber block is fixedly installed on one side of each clamping plate.

[0010] With the above technical solution, the position of the clamping plate is restricted by the sliding rod, which allows the rubber block to better clamp and fix the titration bottle.

[0011] As a further improvement to the above solution, each of the clamping plates is arc-shaped and each of the clamping plates is adapted to the placement platform.

[0012] The above technical solution allows the curved design of the clamping plate to avoid its excessive size affecting the detection slot.

[0013] As a further improvement to the above scheme, each rubber block is arranged in an arc shape, and the arc surface of each rubber block is in contact with the outer surface of the adjacent titration bottle.

[0014] Through the above technical solution, the arc shape of the rubber block can better clamp and fix the titration bottle, preventing the titration bottle from detaching from the placement table and becoming unable to move.

[0015] As a further improvement to the above solution, connecting blocks are fixedly installed on both sides of each rubber block, and two retraction springs are provided between every two adjacent rubber blocks, with both ends of each retraction spring fixedly installed to the adjacent connecting block.

[0016] With the above technical solution, the retraction spring will continuously pull the two rubber blocks to clamp the titration bottle, preventing the two rubber blocks from loosening.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This invention, by setting up a shaking component and a driving component, allows the titrant and the solution to be tested to be placed in the titration bottle. After placing the titration bottle on the shaking component, activating the driving component will cause the shaking component to rotate, thereby causing the fixed titration bottle to rotate as well. The rotation will cause the two liquids inside to shake and mix. This setup can complete the titration test of water-based acrylic resin without requiring the tester to manually shake and mix the liquids, thus avoiding injury to the wrist from prolonged shaking.

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0026] Please combine Figures 1-4 An automatic titration testing device for water-based acrylic resin according to this embodiment includes a testing base 1, a testing platform 2 mounted on the testing base 1, a titration bottle 3 for mixing liquids on the testing platform 2, a burette 4 on one side of the titration bottle 3, multiple clamping assemblies 5 for fixing the burette 4 on the testing platform 2, and multiple shaking components that allow the titration bottle 3 to shake. The testing base 1 has a driving assembly inside to drive the multiple shaking components. The testing platform 2 has multiple testing slots. Each shaking component includes a rotatable platform 601 inside the testing slot and a driving gear 602 fixedly mounted on the platform 601. The driving assembly includes a servo motor 701 inside the testing base 1 and a drive gear 602 fixedly mounted on the servo motor 701. The connecting rod 702 at the end passes through the detection platform 2 and extends into the adjacent detection slot, where it is fixedly installed at the bottom of the adjacent placement table 601. A belt hole is provided between each pair of adjacent detection slots. A timing belt 8 is fitted on multiple drive gears 602 to enable synchronous transmission of the multiple drive gears 602. Each belt hole is adapted to the timing belt 8. The burette 4 is placed on the shaking assembly. After the titrant and the sample to be tested are added, the drive assembly will drive the shaking assembly to shake, thereby accelerating the mixing of the titrant and the sample. The entire shaking process does not require manual operation by the testing personnel, avoiding damage to the testing personnel's wrists due to prolonged shaking. The movement of the timing belt 8 will cause all the drive gears 602 to rotate together, thereby causing all the placement tables 601 to rotate.

[0027] Combination Figures 2-4Each display stand 601 has two sliding holes on both sides, and each display stand 601 has a clamping plate 9 on both sides. Each sliding hole contains a sliding rod 10, one end of which is fixedly installed to the adjacent clamping plate 9. Each clamping plate 9 has a fixedly installed rubber block 11 on one side. Each clamping plate 9 is arc-shaped and fits the display stand 601. Each rubber block 11 is arc-shaped, and the arc-shaped surface of each rubber block 11 is flush with the adjacent... The outer surfaces of the titration bottle 3 are in contact with each other. Each rubber block 11 has a connecting block 12 fixedly installed on both sides. There are two retraction springs 13 between every two adjacent rubber blocks 11. Both ends of each retraction spring 13 are fixedly installed with the adjacent connecting block 12. The position of the clamping plate 9 is restricted by the sliding rod 10. This allows the rubber blocks 11 to better clamp and fix the titration bottle 3. The retraction springs 13 will continuously pull the two rubber blocks 11 to clamp the titration bottle 3, preventing the two rubber blocks 11 from loosening.

[0028] The implementation principle of the automatic titration detection device for water-based acrylic resin in this embodiment is as follows: The titrant is placed in the burette 4, and then the water-based acrylic resin solution to be tested is placed in the titration bottle 3. Two clamping plates 9 are pushed, and under the restriction of the sliding rod 10, the two clamping plates 9 can only move horizontally away from each other. Then, the titration bottle 3 is placed on the placement table 601, and the two clamping plates 9 are released. The return spring 13 pulls the connecting blocks 12 on both sides, causing the two clamping plates 9 to move closer together. This allows the two rubber blocks 11 to clamp the titration bottle 3, preventing it from loosening and separating from the placement table 601. Finally, the servo motor 701 is started, causing the connecting rod 702 to drive the drive gear 602 in a true reverse rotation. This causes the synchronous belt 8 to drive all the drive gears 602 in a true reverse rotation, resulting in the titration bottle 3 on the placement table 601 reversing, thus mixing the internal solution. This setup can complete the titration detection of water-based acrylic resin without requiring manual shaking and mixing by the testing personnel, avoiding wrist injury from prolonged shaking.

Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
