Description

Technical Field

[0001] This application relates to the field of pigment carbon black performance testing technology, and in particular to an automatic sample loading device for pigment carbon black volatiles and its usage method. Background Technology

[0002] Carbon black is an important industrial raw material, widely used in rubber, plastics, inks, coatings, and other fields. Pigment carbon black is a general term for carbon black products used as coloring pigments in inks, paints, coatings, plastics, and other products. It is generally classified into four types according to coloring strength (or blackness) and particle size: high-pigment carbon black, medium-pigment carbon black, ordinary pigment carbon black, and low-pigment carbon black.

[0003] In the testing of pigment carbon black, volatile matter is an important indicator for measuring the content of easily volatile components in carbon black. It represents the mass ratio of substances volatilized when carbon black is heated under specified conditions. The higher the volatile matter content, the worse the quality of the pigment carbon black.

[0004] Currently, the filling of volatile matter samples used to test the volatile matter content of pigment carbon black often relies on manual weighing and filling. This method is time-consuming, and carbon black powder is prone to floating into the air during the filling process, polluting the air and being difficult to clean. Furthermore, the need for long-term manual operation can lead to fatigue of the testing personnel, reducing work efficiency and easily causing errors, which affects the final test results and makes automation difficult.

[0022] Both the feed hopper and the conveying pipe are equipped with vibrating motors, and an adjustable rotary valve is also provided at the connection between the feed hopper and the conveying pipe.

[0023] The adjustable rotary valve is a perforated pin with a through hole on its surface. The perforated pin is rotatably positioned at the connection between the feed hopper and the conveying pipe, and one end of the perforated pin passes through the outer surface of the feed hopper and is connected to the output end of the drive motor.

[0024] Preferably, the quantitative feeding mechanism is a spiral feeding mode, wherein:

[0025] A spiral pin with spiral blades is also provided between the feed hopper and the conveying pipe.

[0040] The technical solutions of this application will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0041] The following is combined with Figures 1-2This application describes the automatic filling device for pigment carbon black volatile matter samples and its usage method provided in the embodiments of this application.

[0042] Reference Figure 1 As shown in the embodiment of this application, the automatic filling device for pigment carbon black volatile matter samples includes a dustproof box 100, a quantitative feeding mechanism 200, a weighing and measuring module 300, a multi-stage vibration module 400, a clamping and positioning module 500, and a laser detection module 600. The dustproof box 100 is equipped with a crucible device for holding pigment carbon black powder. The dustproof box 100 is also equipped with a dustproof cover. The filling operation can only begin when the dustproof cover is closed. The bottom of the dustproof box 100 is also equipped with an operation screen 700 for displaying the measurement results.

[0043] The quantitative feeding mechanism 200 is equipped with pigment carbon black powder to be filled, which can quantitatively feed the pigment carbon black powder to be filled into the crucible to be filled.

[0044] The quantitative feeding mechanism 200 includes a feeding hopper and a conveying pipe. The feeding hopper is located at the top of the dustproof box 100, and one end of the conveying pipe is fixedly connected to the output end of the feeding hopper. The feeding hopper has a funnel-shaped structure that is larger at the top and smaller at the bottom. The inside of the feeding hopper is filled with pigment carbon black powder to be filled. The input end of the feeding hopper extends to the outside of the dustproof box 100 so that the pigment carbon black powder can be added later. The output end of the conveying pipe is located below the multi-stage vibration module 400, which can directionally transport the pigment carbon black powder in the feeding hopper to the crucible to be filled, which is placed above the multi-stage vibration module 400.

[0045] The weighing and measuring module 300 is located at the bottom of the dustproof box 100 and can accurately weigh the crucible placed on it.

[0046] The multi-stage vibration module 400, located below the quantitative feeding mechanism 200, can perform graded vibration on the filling crucible to compact the pigment carbon black powder filled therein.

[0047] The clamping and positioning module 500 is located between the weighing and measuring module 300 and the multi-stage vibration module 400. It is used to clamp the crucible to be filled to the multi-stage vibration module 400 for filling or to clamp the crucible after filling so as to transport it to the weighing and measuring module 300 for weighing and recording.

[0048] The quantitative feeding mechanism 200, in conjunction with the weighing and measuring module 300, achieves the quantitative filling effect of pigment carbon black powder, thereby realizing the automatic filling effect of volatile sample required for testing and reducing its reliance on manual labor.

[0049] The amount of pigment carbon black added is controlled by the quantitative feeding mechanism 200, and the weighing and measuring module 300 automatically weighs the crucible body and the entire crucible after adding pigment carbon black powder. At the same time, the multi-stage vibration module 400 vibrates and compacts the pigment carbon black powder filled into the crucible, and the laser detection module 600 detects the degree of filling. The clamping and positioning module 500 clamps and displaces it, thereby achieving the purpose of automatically filling volatile sample. This solves the problems of long operation time and easy error due to human factors in the existing technology, which leads to reduced accuracy of test results. It improves the detection efficiency and provides a guarantee for the accuracy of the final detection effect.

[0050] Meanwhile, the dustproof box 100 ensures that the entire automatic filling operation is carried out within the dustproof box 100, thus avoiding the problem of carbon black powder floating into the air during operation, polluting the air, and being difficult to clean.

[0051] In some specific embodiments, both the multi-stage vibration module 400 and the weighing measurement module 300 are provided with fixed bases 800 for limiting the crucible, and the top of both fixed bases 800 is provided with limiting grooves that are adapted to the shape of the bottom of the crucible. A horizontal calibration bubble meter is also provided inside the fixed base 800 provided at the multi-stage vibration module 400.

[0052] Specifically, the fixed base 800 facilitates the positioning of the crucible during transport by the clamping and positioning module 500. The limiting groove, which matches the shape of the crucible bottom, is located above the fixed base 800, providing basic limiting for the placement and installation of the crucible. This allows the clamping and positioning module 500 to quickly limit the crucible by simply clamping it to the appropriate location, facilitating quick installation or removal. At the same time, by adding a leveling bubble leveler to the fixed base 800 of the multi-stage vibration module 400, the crucible placed on it can be leveled, providing a measurement basis for the laser measurement module to measure the flatness of the material surface inside the crucible and the distance from the material surface to the rim of the cup.

[0053] In some specific embodiments, the weighing and measuring module 300 includes an integrated electronic balance capable of precisely measuring items placed thereon, with a fixed base 800 disposed above the integrated electronic balance.

[0054] The bottom of the weighing and measuring module 300 is also equipped with an air cushion vibration isolation base to ensure weighing stability. Specifically, before filling begins, the weighing and measuring module 300 can measure and record the weight of the empty crucible placed on it to be filled. After filling is completed, the weighing and measuring module 300 can measure the total weight of the crucible transported on it and the filling material inside. Based on the recorded weight of the empty crucible before filling and the measured total weight after filling, it automatically calculates and saves the actual weight of the filled pigment carbon black powder for later comparison with the weight of the pigment carbon black powder after volatilization, providing data support for the measurement of its volatile matter.

[0055] In some specific embodiments, the multi-stage vibration module 400 includes:

[0056] Low-frequency vibration mode disperses the pigment carbon black powder filled into the crucible through low-frequency vibration;

[0057] The high-frequency vibration mode eliminates the gaps between the pigment carbon black powders dispersed inside the crucible through high-frequency vibration;

[0058] Specifically, the multi-stage vibration module 400 can disperse the pigment carbon black powder filled into the crucible through low-frequency vibration, so that it can be evenly distributed in the internal space of the crucible. It can also eliminate the gaps between the pigment carbon black powders filled into the crucible through high-frequency vibration, making the pigment carbon black powder filled into the crucible more compact. For example, a low-frequency vibration of 10Hz can be used to disperse the sample when dispersing the pigment carbon black powder, while a high-frequency vibration of 50Hz can be used to eliminate gaps when compacting it. At the same time, the amplitude of the vibration device is adjustable so that it can handle pigment carbon black samples of different qualities. Generally speaking, the amplitude for vibrating fine objects can be selected between 0.01-0.5mm to maintain its vibration effect.

[0059] In some specific embodiments, the clamping and positioning module 500 includes a crucible clamp for clamping the crucible and a displacement track for transferring the clamped crucible, wherein the crucible clamp can slide on the displacement track.

[0060] The crucible clamp and the displacement track are each equipped with a corresponding driving device to drive the crucible clamp to hold the crucible or to drive the crucible clamp to slide on the displacement track. The crucible clamp, displacement track and corresponding driving device used are all commonly used facilities in commercially available movable clamping mechanisms. In addition to being able to smoothly drive the filled crucible to move smoothly, there are no additional restrictions. Therefore, they will not be described in detail and will not affect the operation of those skilled in the art.

[0061] Specifically, after the weighing and measuring module 300 measures and records the weight of the empty crucible to be filled, the clamping and positioning module 500 can clamp and transport the weighed empty crucible through the crucible clamp to the multi-stage vibration module 400 located below the quantitative feeding mechanism 200 for filling. After filling is completed, the crucible is clamped and transported back to the weighing and measuring module 300 through the displacement track to measure and record the overall weight of the filled crucible and its filling material.

[0062] In some specific embodiments, the laser measurement module is located at the top of the dustproof box 100. The laser measurement module can monitor the flatness of the material surface formed by the pigment carbon black powder filled into the crucible and the distance between the material surface and the edge of the crucible.

[0063] The laser measurement module includes a laser detector for detecting the material surface and a connecting support rod for providing connection support. The laser detector is located directly above the multi-stage vibration module 400, and one end of the laser detector is fixedly connected to the bottom of the connecting support rod, while the top of the connecting support rod is fixedly connected to the inner wall of the dustproof box 100.

[0064] Specifically, the laser measurement module can monitor and detect the actual filling height of the pigment carbon black powder in the crucible during the filling process and the surface flatness of the material surface formed by it through a laser detector. When the laser detector detects that the material surface formed by the pigment carbon black powder reaches 2mm from the edge of the crucible, the quantitative feeding mechanism 200 will be gradually closed. When the surface of the material surface is detected to be flat, the quantitative feeding mechanism 200 and the multi-stage vibration module 400 will be completely closed to complete the addition and filling of the pigment carbon black powder. Then, the clamping and positioning module 500 will clamp and transport the crucible after filling to the weighing and measurement module 300 for measurement and recording.

[0065] In some specific embodiments, the quantitative feeding mechanism 200 is also equipped with an ultrasonic vibrating plate, which can break up the carbon black powder to be filled loaded inside the quantitative feeding mechanism 200 to avoid powder agglomeration and transportation blockage.

[0066] In some specific embodiments, the quantitative feeding mechanism 200 is a vibration-type feeding mode, wherein:

[0067] Vibration motors are installed at both the feed hopper and the conveying pipe, and an adjustable rotary valve is also installed at the connection between the feed hopper and the conveying pipe;

[0068] The adjustable rotary valve is a perforated pin with a through hole on its surface. The perforated pin is rotatably set at the connection position between the feed hopper and the conveying pipe, and one end of the perforated pin passes through the outer surface of the feed hopper and is connected to the output end of the drive motor.

[0069] Specifically, during operation, the pin can rotate inside the feed hopper under the drive of the drive motor. The rotation amplitude inside the feed hopper is controlled by the drive motor, thereby controlling the opening size of the through hole starting at its surface in the feed hopper, so as to control the degree of opening and closing, and thus achieve the purpose of quantitative feeding.

[0070] In some specific embodiments, the quantitative feeding mechanism 200 is a spiral feeding mode, wherein:

[0071] A spiral pin with spiral blades is also installed between the feed hopper and the conveying pipe. The spiral pin is rotated along the axial direction of the conveying pipe and is installed inside the conveying pipe. One end of the spiral pin protrudes out of the conveying pipe and extends into the inside of the feed hopper.

[0072] Specifically, the spiral pin can be driven by a corresponding drive motor to rotate inside the conveying pipe, thereby conveying the pigment carbon black powder loaded inside the feed hopper to the inside of the conveying pipe. The conveying speed of the spiral pin can be controlled by controlling the speed of the drive motor, thereby achieving the purpose of quantitative feeding.

[0077] Step S3: Monitor the material surface formed by the pigment carbon black powder already filled in the crucible using the laser measurement module. When the material surface reaches 2mm from the edge of the crucible and its surface is flat, turn off the quantitative feeding mechanism 200 and the multi-stage vibration module 400 to stop feeding.

[0078] Step S4: The crucible after filling is clamped by the crucible clamp and then clamped to the weighing measurement module 300 for weighing.
