Description

Technical Field

[0001] This utility model relates to the field of measurement and metrology technology, specifically to a calibration device for an outflow cup viscometer. Background Technology

[0002] Viscosity, also known as viscosity, refers to the resistance a fluid exhibits to flow. Measuring viscosity yields the viscosity value of a fluid, allowing for the assessment of its flowability and performance. An outflow cup is a tool used to measure the viscosity of liquids, typically for rapid viscosity measurements in workshops or on-site. The working principle of an outflow cup is to calculate the viscosity of the liquid by measuring the time it takes for the liquid to flow out of the cup. It is widely used in industries such as coatings, inks, adhesives, and petrochemicals. Viscosity is crucial for production processes and quality control in these industries, making viscosity measurement essential. When calibrating an outflow cup, adjust the stand to be level and place the outflow cup on it. Block the outflow hole with your finger, pour the pre-temperatured standard solution along the inner wall of the outflow cup until the liquid overflows, let it stand until air bubbles escape, and immediately use a straight-edged scraper to smooth the liquid surface until it is level with the upper edge of the outflow cup. Start timing when you remove your finger from the outflow tube. The liquid should flow out of the outflow tube in a straight line. Stop timing the moment the flow stops and record the outflow time. In real-world work, the time lag between finger removal and stopwatch timing will inevitably affect the measurement results. Furthermore, when one hand's fingers are used to block the outlet, steps such as pouring liquid, leveling, and timing can only be performed with the other hand, making the process more cumbersome and reducing work efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a calibration device for an outflow cup viscometer, which solves the problem that the time interval between the removal of the finger and the stopwatch timing during measurement affects the measurement results. It also solves the problems of cumbersome measurement steps and low work efficiency.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an effluent cup viscometer calibration device, comprising a base and a vertical rod fixed on the base, a fixing block fixedly connected to the vertical rod, a rotating motor mounted on one end of the fixing block, a rotating rod connected to the output end of the rotating motor, a baffle fixedly connected to the side end of the rotating rod, a slider with a fixing screw slidably connected to the vertical rod, a support rod fixedly connected to one end of the slider, a platform mounted on the other end of the support rod, a through groove opened on the platform, a clamping assembly installed in the through groove, an effluent cup fixedly fixed in the clamping assembly, the baffle fitting against the bottom of the effluent cup, a beaker placed on the base, the beaker located directly below the effluent cup.

[0005] With the above structural design, this utility model uses a baffle to block the outlet hole of the outlet cup, so that the steps of pouring liquid and scraping can be completed by both hands, making the outlet cup calibration process simpler and more convenient, and reducing the reaction time error of the process of removing the finger and starting the timer.

[0006] Preferably, the clamping assembly includes a drive motor fixedly connected to the side wall of the shelf, the output end of the drive motor extending into the through groove and fixed at the middle position of the rotating rod, push-pull rods rotatably connected to both ends of the rotating rod, and movable blocks rotatably connected to the other end of the push-pull rods, with arc-shaped clamps fixedly connected to the opposite sides of the two movable blocks, and a sliding groove provided on the inner side wall of the through groove, with the movable blocks slidably connected to the sliding groove.

[0007] The above design allows the clamping assembly to adjust two arc-shaped clamps to accommodate different types of dispensing cups, avoiding the need to change the shelf and readjust the level for multiple dispensing cups, thus improving work efficiency.

[0008] Preferably, a timer is installed on one side of the fixing block.

[0009] The above design incorporates a timer linked to a rotating motor. When the motor starts, the rotating rod moves clockwise, causing the liquid to flow out and simultaneously triggering the timer, resulting in more accurate timing.

[0010] Preferably, the base is provided with leveling feet at the four corners of its lower end, and a level bubble is installed at the upper end of the base.

[0011] With the above structural design, the base can be leveled by adjusting the level feet, and the level bubble can be used to observe whether the base is level.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model sets up a timer linked to a rotating motor. When the rotating motor starts, the rotating rod moves clockwise, causing the liquid to flow out, and at the same time triggers the timer to start timing. This reduces the reaction time error between the removal of the finger and the start of timing, making the timing more accurate. At the same time, a baffle is used to block the outlet hole of the outlet cup, so that the steps of pouring liquid and scraping can be completed by both hands, making the outlet cup calibration process simpler and more convenient.

[0014] 2. The clamping assembly has two adjustable arc-shaped clamps to accommodate different models of dispensing cups, avoiding the need to change the shelf and readjust the level after multiple dispensing cups are used, thus improving work efficiency. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figs. 1 to 4 This utility model provides a technical solution: an effluent cup viscometer calibration device, including a base 1 and a vertical rod 2 fixed on the base 1. A fixing block 3 is fixedly connected to the vertical rod 2. A rotating motor 5 is installed at one end of the fixing block 3. A rotating rod 9 is connected to the output end of the rotating motor 5. A baffle 10 is fixedly connected to the side end of the rotating rod 9. A slider 15 with a fixing screw 12 is slidably connected to the vertical rod 2. A support rod 11 is fixedly connected to one end of the slider 15. A platform 4 is installed at the other end of the support rod 11. A through groove 17 is opened on the platform. A clamping assembly 6 is installed in the through groove 17. An effluent cup 7 is fixed in the clamping assembly 6. The baffle 10 is in contact with the bottom of the effluent cup 7. A beaker 8 is placed on the base 1. The beaker 8 is located directly below the effluent cup 7. A rubber pad 606 is provided on the side of the arc-shaped clamp 603 near the outflow cup 7. The rubber pad 606 acts as a buffer when the arc-shaped clamp 603 clamps the outflow cup 7, preventing the arc-shaped clamp 603 from directly contacting the outflow cup 7 and causing damage to the outflow cup 7. At the same time, the rubber pad 606 increases the friction when clamping the outflow cup 7, making it easier to fix the outflow cup 7.

[0021] The clamping assembly 6 includes a drive motor 601 fixedly connected to the side wall of the platform 4. The output end of the drive motor 601 extends into the through groove 17 and is fixed at the middle position of the rotating rod 604. Both ends of the rotating rod 604 are rotatably connected to push-pull rods 605. The other end of the push-pull rod 605 is rotatably connected to a movable block 602. The two movable blocks 602 are fixedly connected to the opposite sides of an arc-shaped clamping plate 603. A sliding groove 607 is provided on the inner side wall of the through groove 17. The movable block 602 is slidably connected to the sliding groove 607.

[0022] A timer 16 is installed on one side of the fixing block 3, and the timer 16 is electrically connected to the rotating motor 5. The timer 16 is linked to the rotating motor 5. When the rotating motor 5 is started, the rotating rod 9 moves clockwise, causing the liquid to flow out, and at the same time, the timer 16 is triggered to start the time, making the timing more accurate.

[0023] The base 1 is equipped with horizontal adjustment feet 13 at the four corners of its lower end, and a horizontal bubble 14 is installed on the upper end of the base 1.

[0024] Working principle: Before viscosity measurement, the operator needs to adjust the leveling foot 13 to make the level bubble 14 in the middle position, place the outflow cup 7 on the stage 4, start the drive motor 601 to drive the rotating rod 604 to rotate, thereby pulling the two arc-shaped clamps 603 closer to each other, thus clamping the outflow cup 7 and ensuring that the upper edge of the outflow cup 7 is horizontal. Adjust the height of the stage 4 so that the baffle 10 is in contact with the bottom of the outflow cup 7, and use the baffle to block the outflow hole of the outflow cup. Fix the height of the stage 4 with the fixing screw 12. Place a clean beaker 8 on the base 1 so that the outflow hole of the outflow cup 7 is aligned with the center of the beaker 8. According to the standard requirements, pour the standard solution that has reached the test temperature of ±0.1℃ into the inner wall of the outflow cup 7 until the liquid overflows. After standing until there are no more bubbles, immediately use a scraper to scrape the liquid surface until it is level with the upper edge of the outflow cup. Start the rotating motor 5 to make the baffle 10 rotate clockwise and trigger the timer 16. At the moment when the liquid flow stops, start the rotating motor 5 to rotate the baffle 10 counterclockwise and the timer 16 stops.
