Abstract
Description
Technical Field
[0001] This utility model relates to the field of viscosity detection technology, specifically a glue viscosity detection device. Background Technology
[0002] Adhesive viscosity is an important indicator for measuring the flow properties of adhesives. It directly affects the application effect and scope of use of adhesives. In the process of adhesive production and use, accurate measurement of adhesive viscosity is of great significance for ensuring product quality and optimizing process parameters. Traditional adhesive viscosity testing methods mainly rely on manual operation of rotational viscometers, calculating the viscosity value by measuring the rotation speed of the rotor in the adhesive.
[0003] However, the commonly used method of adjusting the rotor position by lowering the main unit is inconvenient and can easily cause the horizontal angle of the main unit to deviate, affecting the measurement accuracy. In addition, since the main unit is relatively heavy compared to the support structure, repeated adjustments can easily increase the gap between the support structure and the main unit, affecting the stability of the main unit. Furthermore, when manually adjusting the lowering range of the main unit, the rotor scale is easily subjected to large errors when viewed at an angle, as it is flush with the glue surface. These factors limit the accuracy and convenience of rotational viscometers in practical applications. Therefore, a glue viscosity testing device is needed to overcome the existing shortcomings. Utility Model Content
[0004] The purpose of this invention is to provide a glue viscosity testing device. By setting a clamping mechanism, the rotor is prevented from rotating inside the sample cup, which would cause slight displacement of the sample cup, thereby improving the accuracy of the measurement. By setting a lifting mechanism, the length of the rotor inserted into the sample cup is appropriate, reducing the error caused by manual adjustment.

[0007] The present invention is further configured such that the clamping mechanism includes a clamping block, a moving rod, a guide rod, and a return spring.

The inner side of the drive ring has an inclined surface, the bottom end of the moving rod has an inclined surface, and the inclined surface of the moving rod is in contact with the inclined surface of the drive ring.
[0010] The present invention is further configured such that a sleeve is fixedly connected to the outer side of the fixed base, and a push block is movably connected inside the sleeve. The front side of the push block has a beveled surface, and the beveled surface of the push block is in contact with the bottom end of the drive ring. An adjusting rod is threadedly connected to the end of the sleeve. The front end of the adjusting rod is in contact with the tail end of the push block. A compression spring is sleeved on the outer side of the adjusting rod. One end of the compression spring is fixedly connected to the tail end of the push block, and the other end of the compression spring is fixedly connected to the inside of the sleeve.
[0011] The present invention is further configured such that the lifting mechanism includes a guide column, a connecting block, and a driving column. The driving column is movably connected to the inside of the guide column via a bearing. The connecting block passes through the guide column and is movably connected to the guide column. The guide column is movably connected to the bottom inner side of the fixed seat. The outer side of the connecting block is fixedly connected to the inner side of the fixed seat. The outer side of the driving column is threaded. The driving column passes through the connecting block and is threadedly connected to the connecting block.

[0014] This utility model has the following beneficial effects:
[0015] 1. The present invention uses a clamping mechanism in which the bottom inclined surface of the moving rod abuts against the inner inclined surface of the drive ring, thereby pushing the moving rod closer to each other along the slide groove. This causes the return spring to compress and shorten, thereby controlling the clamping blocks to move closer to each other, thus providing a strong clamping grip on the outside of the sample cup. This helps to maintain the stability of the sample cup and prevents the rotor from rotating inside the sample cup, which could cause slight displacement of the sample cup, thereby improving the accuracy of the measurement.

The sensor at the bottom of the main unit automatically controls the distance the sample cup rises, ensuring that the length of the rotor inserted into the sample cup is appropriate and reducing errors caused by manual adjustment.

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0026] like Figure 1-6 As shown, this utility model provides a technical solution: an adhesive viscosity testing device, including a bracket 1, a support rod 2 fixedly connected to the top of the bracket 1, and a main unit 3 fixedly connected to the top of the support rod 2. The rotor is typically lowered by lowering the main unit 3, but this method is inconvenient and easily causes the main unit 3 to deviate horizontally. Furthermore, the main unit 3 is relatively heavy compared to the support structure, and repeated adjustments can easily increase the gap between the support structure and the main unit 3, affecting the support effect of the main unit 3. Manually adjusting the lowering range of the main unit 3 also results in a large error, particularly when the rotor scale is observed obliquely and aligned with the adhesive surface. A connecting box 4 is fixedly connected to the inner side of the bracket 1, and a base plate 5 is fixedly connected to the other end of the connecting box 4. A fixing seat 6 is provided at the top of the base plate 5, and a sample cup 7 is placed at the top of the fixing seat 6. A clamping mechanism 8 is movably connected inside the fixing seat 6 and is movably connected to the outer side of the sample cup 7. A lifting mechanism 9 is provided at the bottom of the main unit 3 and is connected to the bottom of the fixing seat 6.
[0027] like Figure 1 , Figure 3 , Figure 5 and Figure 6As shown, the clamping mechanism 8 includes a clamping block 801, a moving rod 802, a guide rod 803, and a return spring 804. The clamping block 801, moving rod 802, guide rod 803, and return spring 804 are all arranged in a circular array. The top ends of the moving rods 802 are fixedly connected to the bottom ends of the clamping blocks 801. The guide rods 803 pass through the moving rods 802 and are movably connected to them. The return springs 804 are sleeved on the outer sides of the guide rods 803. The top end of the fixed base 6 has several sliding grooves 10. The guide rods 803 are fixedly connected to the inside of the sliding grooves 10. One end of the return spring 804 is fixedly connected to the inside of the sliding groove 10, and the other end is fixedly connected to the outer side of the moving rod 802. The inner side of the clamping block 801 is in contact with the outer side of the sample cup 7. The clamping mechanism 8 also includes a drive ring 805. The fixed base 6 has an annular groove 11 inside. The drive ring 805 is movably connected to the inside of the annular groove 11, and the sliding groove 10 is connected to the annular groove 11. The inner side of the drive ring 805 has a bevel, and the bottom end of the moving rod 802 has a bevel. The bevel of the moving rod 802 fits against the bevel of the drive ring 805. The outer side of the fixed base 6 is fixedly connected to a sleeve 12. The inside of the sleeve 12 is movably connected to a push block 13. The front side of the push block 13 has a bevel. The bevel of the push block 13 fits against the bottom end of the drive ring 805. The end of the sleeve 12 is threadedly connected to an adjusting rod 14. The front end of the adjusting rod 14 fits against the tail end of the push block 13. A compression spring 15 is sleeved on the outer side of the adjusting rod 14. One end of the compression spring 15 is fixedly connected to the tail end of the push block 13, and the other end of the compression spring 15 is fixedly connected to the inside of the sleeve 12.
[0028] The sample cup 7 is placed on the top of the fixed base 6. Then, the adjusting rod 14 is rotated inward to push the push block 13 forward, causing the compression spring 15 to stretch and lengthen. The beveled surface of the push block 13 fits against the bottom end of the drive ring 805 inside the annular groove 11, pushing the drive ring 805 to move upward inside the annular groove 11. Since the bottom bevel of the moving rod 802 abuts against the inner bevel of the drive ring 805, the moving rod 802 is pushed closer to each other along the slide groove 10, causing the return spring 804 to compress and shorten. This controls the clamping blocks 801 to move closer to each other, thereby forcefully clamping the outside of the sample cup 7, which helps to maintain the stability of the sample cup 7 and prevents the rotor from rotating inside the sample cup 7, causing slight displacement of the sample cup 7, thus improving the accuracy of the measurement.
[0029] like Figure 1 , Figure 2 and Figure 4As shown, the lifting mechanism 9 includes a guide column 901, a connecting block 902, and a drive column 903. The drive column 903 is movably connected to the interior of the guide column 901 via a bearing. The connecting block 902 passes through the guide column 901 and is movably connected to the guide column 901. The guide column 901 is movably connected to the inner bottom of the fixed base 6. The outer side of the connecting block 902 is fixedly connected to the inner side of the fixed base 6. The outer side of the drive column 903 is threaded, and the drive column 903 passes through the connecting block 902 and is threadedly connected to the connecting block 902. The bottom end of the guide column 901 is fixedly connected to the top end of the base plate 5, and the drive column 903... The bottom end of 03 is movably connected to the inside of the base plate 5. A synchronous ring 16 is fixedly connected to the outer side of the bottom end of the drive column 903. A control rod 17 is movably connected to the inside of the support rod 2. A synchronous ring 18 is fixedly connected to the bottom end of the control rod 17. A synchronous belt 19 is sleeved on the outer side of the synchronous ring 16 and the synchronous ring 18. The synchronous belt 19 is movably connected to the inside of the bracket 1, the inside of the connecting box 4, and the inside of the base plate 5, respectively. The synchronous ring 16, the synchronous ring 18, and the synchronous belt 19 constitute a belt drive structure. A servo motor 20 is fixedly connected to the inside of the main unit 3, and the output end of the servo motor 20 is fixedly connected to the top end of the control rod 17.
[0030] After installing the rotor at the bottom of the main unit 3, the servo motor 20 is started, driving the control lever 17 and the second synchronous ring 18 to rotate. Under the action of the synchronous belt 19, the first synchronous ring 16 is driven to rotate, thereby causing the drive column 903 to rotate inside the guide column 901. Since the drive column 903 is threadedly connected to the connecting block 902, and the guide column 901 restricts the movement direction of the connecting block 902, the connecting block 902 drives the fixed seat 6 to move upward synchronously, thereby lifting the sample cup 7 upward until the rotor is inserted into the sample cup 7. At the same time, the scale on the outside of the rotor is flush with the surface of the glue, avoiding the need to lower the rotor by operating the main unit 3. The sensor at the bottom of the main unit 3 automatically controls the distance the sample cup 7 rises, so that the length of the rotor inserted into the sample cup 7 is appropriate, reducing the error caused by manual adjustment.
[0031] Working principle: In use, first, add glue to the inside of the sample cup 7 until the surface of the glue is flush with the scale on the inside of the sample cup 7. Then, place the sample cup 7 on the top of the fixing base 6. Next, rotate the adjusting rod 14 inward to push the push block 13 forward, causing the compression spring 15 to stretch and lengthen. The beveled surface of the push block 13 fits against the bottom end of the drive ring 805 inside the annular groove 11, pushing the drive ring 805 upward inside the annular groove 11. Since the beveled surface at the bottom of the moving rod 802 abuts against the beveled surface inside the drive ring 805, the moving rod 802 is pushed closer together along the slide groove 10, causing the return spring 804 to compress and shorten. This controls the clamping blocks 801 to move closer together, thereby controlling the sample cup 7. The rotor is then firmly clamped from the side. Next, the rotor is installed at the bottom of the main unit 3. Then, the servo motor 20 is started, driving the control lever 17 and the second synchronous ring 18 to rotate. Under the action of the synchronous belt 19, the first synchronous ring 16 is driven to rotate, thereby causing the drive column 903 to rotate inside the guide column 901. Since the drive column 903 is threadedly connected to the connecting block 902, and the guide column 901 restricts the movement direction of the connecting block 902, the connecting block 902 drives the fixed seat 6 to move upward synchronously, thereby lifting the sample cup 7 upward until the rotor is inserted into the sample cup 7. At the same time, the scale on the outside of the rotor is flush with the surface of the glue, and the sample cup 7 is stopped. Then, the main unit 3 is used to control the rotor to rotate, and the viscosity parameters of the glue are obtained through the display screen.
