Description

Technical Field

[0001] This utility model belongs to the field of optical testing equipment technology, and in particular relates to an adjustable carbon black tester. Background Technology

[0002] Carbon black is a black powdery substance composed of carbon elements. It possesses excellent coloring, reinforcing, and electrical properties, and is widely used in industries such as rubber, plastics, coatings, and inks. It is an indispensable functional filler in the production of these products—improving wear resistance in rubber products, providing light-blocking and anti-aging properties in plastic products, and primarily serving a coloring function in coatings and inks. To ensure that carbon black meets application standards, its key properties such as blackness, hue, and dispersion uniformity need to be tested. A carbon black tester is the core equipment that precisely acquires optical signals from samples to achieve quantitative analysis of these properties, directly impacting the quality control and production stability of downstream products.

[0003] Currently available carbon black testing instruments have significant drawbacks during testing: Because carbon black samples need to be manufactured in different thicknesses for various applications, when the instrument's testing port is directly aligned with the sample, the end of the instrument closest to the testing port is prone to tilting due to the sample's thickness, creating a gap between the testing port and the sample. Ambient light can then enter the testing area through this gap, interfering with the instrument's accurate acquisition of the sample's optical signals. This leads to distortion of key test data such as blackness and hue difference, failing to provide reliable data for carbon black performance evaluation and product manufacturing adjustments, and severely impacting the accuracy and consistency of the test results. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable carbon black tester, which solves the problem that existing carbon black testers have a problem with the carbon black sample thickness. When the instrument is directly aligned with the sample, the test port end is prone to warping and forming a gap, which leads to interference from external ambient light, data distortion, and possible damage to the sample due to excessive pressure.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to an adjustable carbon black tester, comprising a base, a lifting assembly, and a loading platform. The lifting assembly includes a hollow column fixedly installed on the top of the base. The loading platform includes a clamping sleeve fixedly installed on the periphery of the hollow column. A base plate is fixedly installed on one side of the clamping sleeve. Two limiting bushings are fixedly connected to the top of the base plate. A connecting shaft is slidably fitted inside each of the two limiting bushings. The loading plate is fixedly connected to the top of both connecting shafts. A hydraulic buffer located below the loading plate is also fixedly installed on the top of the base plate.

[0007] The present invention is further configured such that a lower sleeve is slidably fitted on the inner circumferential side of the hollow column, and a screw is fixedly connected to the inner circumferential side of the lower sleeve, and two symmetrical limiting grooves are opened on the circumferential side of the screw.

[0008] The present invention is further configured such that a connecting sleeve is rotatably installed on the top of the hollow column, and the connecting sleeve is threadedly connected to the screw.

[0009] The present invention is further configured such that a connecting ring is fixedly installed on the periphery of the hollow column, and two symmetrical locking teeth are fixedly connected to the inner periphery of the connecting ring, and the two locking teeth slide in cooperation with the two limiting grooves respectively.

[0010] The present invention is further configured such that a handwheel is fixedly connected to the peripheral side of the connecting sleeve.

[0011] The present invention is further configured such that an upper sleeve is fixedly connected to the top of the screw, an mounting plate is fixedly connected to the periphery of the upper sleeve, and the tester body is fixedly mounted on one side of the mounting plate.

[0012] This utility model has the following beneficial effects:

[0013] This invention utilizes the cooperation of the screw, connecting sleeve, handwheel, connecting ring, locking teeth, and limiting groove in the lifting assembly, as well as the cooperation of the limiting bushing, connecting shaft, and hydraulic buffer in the platform. When the handwheel is turned, the locking teeth and limiting groove restrict the screw to rotate with the connecting sleeve, converting the rotation of the connecting sleeve into linear lifting of the screw, which drives the tester body to rise and fall smoothly. This solves the problem that the carbon black sample thickness causes the instrument's test port end to warp and fail to adhere to the sample. At the same time, when the test port is pressed down, the connecting shaft guides the platform along the limiting bushing, and the hydraulic buffer buffers the pressure to prevent sample damage or data distortion. Furthermore, the state of its telescopic rod allows for quick judgment of whether the fit is in place, eliminating the need for repeated adjustments. This ensures stable test conditions, shortens test preparation time, and improves efficiency.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0022] 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 skilled in the art without creative effort are within the protection scope of the present utility model. Specific Implementation

[0024] Please see Figure 1-4 This utility model is an adjustable carbon black tester, including a base 1, a lifting component 2 and a platform. The lifting component 2 includes a hollow column 3 fixedly installed on the top of the base 1. The platform includes a clamping sleeve 4 fixedly installed on the side of the hollow column 3. A base plate 5 is fixedly installed on one side of the clamping sleeve 4. Two limiting bushings 6 are fixedly connected to the top of the base plate 5. A connecting shaft 7 is slidably fitted inside the two limiting bushings 6. A platform 8 is fixedly connected to the top of the two connecting shafts 7. A hydraulic buffer 19 located below the platform 8 is also fixedly installed on the top of the base plate 5.

[0025] The clamping sleeve 4 is used to fix the stage to the hollow column 3 to ensure the stability of the stage position; the base plate 5 provides a mounting carrier for the limiting bushing 6 and the hydraulic buffer 19; the limiting bushing 6 slides with the connecting shaft 7 to limit and guide the up and down movement of the stage 8, preventing the stage 8 from shifting after the carbon black sample is placed; the stage 8 is used to place the carbon black sample, providing a flat testing platform for the sample; the hydraulic buffer 19 can buffer the stage 8 when it is squeezed, preventing the test port of the test instrument body 18 from excessively squeezing the sample, and by observing the extension and retraction state of the telescopic rod of the hydraulic buffer 19, it can be determined whether the test port and the sample are properly fitted.

[0026] Specifically, a lower sleeve 9 is slidably fitted on the inner circumferential side of the hollow column 3, and a screw 10 is fixedly connected to the inner circumferential side of the lower sleeve 9. Two symmetrical limiting grooves 12 are opened on the circumferential side of the screw 10. A connecting sleeve 11 is rotatably installed on the top of the hollow column 3. The connecting sleeve 11 is threadedly connected to the screw 10. A handwheel 15 is fixedly connected to the circumferential side of the connecting sleeve 11. A connecting ring 13 is fixedly installed on the circumferential side of the hollow column 3. Two symmetrical locking teeth 14 are fixedly connected to the inner circumferential side of the connecting ring 13. The two locking teeth 14 are slidably fitted with the two limiting grooves 12 respectively.

[0027] The lower sleeve 9 slides with the hollow column 3 and is fixedly connected to the screw 10. It can move up and down with the screw 10, providing auxiliary guidance for the movement of the screw 10. The screw 10 is the core component for realizing the lifting function. Through the threaded engagement with the connecting sleeve 11, it converts the rotational motion of the connecting sleeve 11 into its own linear motion. The limiting groove 12 slides with the locking tooth 14 to prevent the screw 10 from rotating with the connecting sleeve 11 during the up and down movement, ensuring that the screw 10 only performs linear lifting and lowering motion. The connecting sleeve 11 is threadedly connected to the screw 10. Rotating the connecting sleeve 11 can drive the screw 10 to move up and down. The handwheel 15 facilitates the operator to apply force. By rotating the handwheel 15, the connecting sleeve 11 can be easily rotated, thereby controlling the lifting and lowering of the screw 10. The connecting ring 13 is used to fix the locking tooth 14, providing installation support for the locking tooth 14 and ensuring that the locking tooth 14 can stably engage with the limiting groove 12.

[0028] The top of the screw 10 is fixedly connected to an upper sleeve 16, and a mounting plate 17 is fixedly connected to the side of the upper sleeve 16. The tester body 18 is fixedly mounted on one side of the mounting plate 17. The upper sleeve 16 connects the screw 10 to the mounting plate 17, so that the lifting and lowering movement of the screw 10 can be transmitted to the mounting plate 17. The mounting plate 17 provides an installation position for the tester body 18, ensuring that the tester body 18 can be stably fixed and can move up and down together with the mounting plate 17. The tester body 18 is used to test carbon black samples. By lifting and lowering the screw 10, the distance between its test port and the sample on the carrier plate 8 can be adjusted to achieve contact between the test port and the sample, ensuring test accuracy.

[0029] The operation process in this embodiment is as follows: First, place the carbon black sample on the carrier plate 8. Then, the operator turns the handwheel 15, which drives the connecting sleeve 11 to rotate at the top of the hollow column 3. Since the connecting sleeve 11 is threadedly connected to the screw 10, and the screw 10 cannot rotate because it is engaged with the retaining teeth 14 on the connecting ring 13 through the limiting groove 12, the rotation of the connecting sleeve 11 is converted into the downward linear motion of the screw 10. When the screw 10 moves down, it drives the mounting plate 17 and the tester body 18 to move down together through the upper sleeve head 16. As the test port of the tester body 18 gradually approaches the sample on the carrier plate 8... Continue turning handwheel 15. The test port will contact the sample and exert downward pressure on the carrier plate 8. The carrier plate 8 will drive the connecting shaft 7 to slide downward within the limiting sleeve 6, while simultaneously squeezing the hydraulic buffer 19. When the telescopic rod of the hydraulic buffer 19 begins to retract, it indicates that the test port has been properly aligned with the sample. Stop turning handwheel 15 and start the tester body 18 for testing. After the test is completed, turn handwheel 15 in the opposite direction to drive the connecting sleeve 11 to rotate in the opposite direction, causing the screw 10 to move upward, which in turn drives the tester body 18 to rise and reset. Then, remove the sample that has been tested.
