Description

Technical Field

[0001] This application relates to the technical field of material testing, and in particular to an oil injection system for determining the oil absorption value of powder. Background Technology

[0002] Powder materials are widely used in industrial production, and the oil absorption value of powders, as an important indicator of their performance, plays a crucial role in product quality control and process optimization. Accurate understanding of the oil absorption value helps companies rationally adjust production formulas, improve product quality stability, reduce production costs, and ultimately enhance market competitiveness. Therefore, the development of powder oil absorption value measurement technology is of great significance for the efficient and stable operation of industrial production. With the continuous development of industry, the requirements for the accuracy and efficiency of powder oil absorption value measurement are also increasing.

[0003] Currently, in the determination of oil absorption value of powders, the oiling operation is mostly done manually, although mechanical devices are sometimes used. However, both manual operation and existing mechanical oiling methods generally suffer from inaccurate control of the oiling speed and amount, resulting in insufficient and uneven mixing of the powder and oil. This deficiency directly affects the accuracy of the final oil absorption value measurement result, causing data deviation and reducing the overall measurement precision. Utility Model Content

[0004] To address the problem of inaccurate control of oil injection speed and volume, which affects the accuracy of the final oil absorption value measurement, this application aims to provide an oil injection system for the powder oil absorption value measurement process. The technical solution adopted is as follows: Includes an injection pump and a three-axis fine-tuning platform; The injection pump includes an actuator and a syringe. The syringe is mounted on the actuator and is used to apply pressure to the bottom of the syringe intermittently. The injection nozzle of the syringe is connected to one end of a hose, and the other end of the hose is an injection port located at the oil filling port above the expansion zone of the tank. The three-axis fine-tuning platform is used to clamp and control the position of the injection port.

[0005] By adopting the above technical solution, combining the injection pump with a three-axis fine-tuning platform, the oil injection process is automated and precisely controlled. The injection pump's actuator applies pressure intermittently, ensuring that the oil is injected into the powder at a stable and controllable speed, avoiding measurement errors caused by oil droplets being too fast or too slow. Simultaneously, the three-axis fine-tuning platform allows for fine-tuning of the injection port position, ensuring the injection point is accurately located at the injection port in the tank's expansion zone. This improves the accuracy and repeatability of powder oil absorption value measurement and reduces the impact of human operation.

[0006] Optionally, the actuator includes a base, a first telescopic rod, and a fixing assembly for fixing the syringe, wherein the first telescopic rod is disposed within the base.

[0007] By adopting the above technical solution, the actuator is defined as including a base, a first telescopic rod, and a fixing component, providing a stable support structure. The base serves as the basic platform, the first telescopic rod is responsible for pushing the syringe, and the fixing component ensures that the syringe remains fixed during the injection process, preventing the syringe from shaking or shifting, thereby enhancing the stability and reliability of the system and reducing measurement deviations caused by equipment vibration.

[0008] Optionally, the end of the first telescopic rod is provided with an abutment plate, which abuts against the bottom of the syringe, and the syringe and the first telescopic rod are located on the same side of the abutment plate.

[0009] By adopting the above technical solution, uniform pressure is applied to the syringe. This design avoids syringe damage or uneven oil dispensing caused by pressure concentration, ensures that the oil flows at a constant speed, and improves the control accuracy and consistency of the oil injection process.

[0010] Optionally, the fixing component includes a buckle and a second telescopic rod, wherein the buckle is fixedly connected to one end of the second telescopic rod and the other end is disposed in the base.

[0011] By adopting the above technical solution, rapid fixation and release of the syringe are achieved. The buckle, in conjunction with the second telescopic rod, allows for flexible adjustment of the clamping force, facilitating syringe replacement or cleaning, improving the system's operational convenience and maintenance efficiency, and reducing downtime.

[0012] Optionally, the inner side of the buckle is arc-shaped, corresponding to the shape of the outer wall of the syringe, and the inner side of the buckle abuts against the outer wall of the syringe.

[0013] By adopting the above technical solution, the inner side of the buckle is designed to be arc-shaped, corresponding to the shape of the syringe's outer wall, thus enhancing the fixing effect. The arc-shaped buckle fits tightly against the syringe's outer wall, providing a larger contact area and preventing the syringe from sliding or rotating under pressure, further ensuring the stability and safety of the injection process.

[0014] Optionally, the three-axis fine-tuning platform includes a lead screw, a guide rail, a slider, and a coupling. The lead screw, guide rail, slider, and coupling form a set of moving units. There are three sets of moving units, which are set and connected in the XYZ direction. The couplings of each set are connected to a servo motor.

[0015] By adopting the above technical solution, high-precision three-dimensional positioning is achieved. This design allows for micron-level adjustment of the injection port in the X, Y, and Z directions, enabling the injection point to be precisely aligned with the target area. This improves the flexibility and adaptability of the measurement, making it suitable for testing different powder samples.

[0016] Optionally, the three-axis fine-tuning platform is also equipped with grippers, which are used to hold the injection port of the tubing.

[0017] By adopting the above technical solution, a gripper is installed on the three-axis fine-tuning platform to hold the injection port of the tubing, ensuring the stability of the injection port during movement. The gripper effectively prevents oil injection position deviation caused by tubing shaking or bending, thereby ensuring accurate injection of oil into the designated point and improving the repeatability and accuracy of the measurement.

[0018] Optionally, the injection port is composed of a rigid needle, which is sealed to the tubing via a connector and is moved by the three-axis fine-tuning platform.

[0019] By adopting the above technical solution, using a rigid needle as the injection port and sealing it with a hose via a connector, and moving it using a three-axis fine-tuning platform, the directionality and sealing of the oil injection are improved. The rigid needle reduces vibration and deviation during oil injection, and the sealed connection prevents oil leakage, ensuring accurate and efficient injection of oil into the powder, reducing waste and the risk of contamination.

[0020] In summary, this application includes at least one of the following beneficial technical effects: 1. By combining an injection pump with a three-axis fine-tuning platform, the oil injection process is automated and precisely controlled. The injection pump's actuator applies pressure intermittently, ensuring that the oil is injected into the powder at a stable and controllable rate, avoiding measurement errors caused by oil droplets being too fast or too slow. Simultaneously, the three-axis fine-tuning platform allows for fine-tuning of the injection port position, ensuring the injection point is accurately located at the injection port in the tank's expansion zone. This improves the accuracy and repeatability of powder oil absorption value measurement and reduces the impact of human operation. 2. The system features targeted designs in its actuator and fixing components to ensure the stability and reliability of the oil injection process. The actuator applies pressure evenly through the abutment plate, while the fixing components use arc-shaped clips to tightly fit the syringe, jointly preventing shaking, slippage, or uneven pressure during operation. This structure also facilitates the quick installation and replacement of the syringe, improving the ease of operation and maintenance efficiency, and providing hardware support for continuous and stable testing. 3. The system further enhances performance through gripper fixation and a rigid needle design. The grippers ensure the stability of the tubing injection port during movement, preventing positioning inaccuracies caused by tubing sway; the rigid needle provides better directionality and rigidity, and together with the sealing connector, effectively prevents oil leakage and drip deviation. These optimizations in terminal details collectively ensure that every drop of oil is accurately and efficiently injected into the target powder, thereby improving overall measurement precision and reducing waste.

[0022] The following is in conjunction with the appendix Figure 1 -Appendix Figure 2 This application will be described in further detail below.

[0023] An oil injection system for determining the oil absorption value of powder, referring to Figure 1 It includes an injection pump 1 and a three-axis fine-tuning platform 2. The injection pump 1 is used to inject oil into the expansion zone of the tank, and the three-axis fine-tuning platform 2 is used to precisely control the position of the injection port 131. This combination can achieve precise oil injection and improve the accuracy of the measurement. The expansion zone is the annular part of the tank with a large space between the rotating cylinder and the fixed cylinder.

[0024] Specifically, refer to Figure 1The syringe pump 1 includes an actuator 11 and a syringe 12. The actuator 11 includes a base 111, a first telescopic rod 112, and a fixing assembly 113 for fixing the syringe 12. The base 111 is typically made of metal or high-strength plastic and has a stable structure that provides support for the entire actuator 11. The first telescopic rod 112 can be an electrically operated or hydraulically operated telescopic rod and is located within the base 111. The end of the first telescopic rod 112 has an abutment plate 114, which is generally a round or square metal plate with a smooth surface. It abuts against the bottom of the syringe 12, and the syringe 12 and the first telescopic rod 112 are located on the same side of the abutment plate 114. When the first telescopic rod 112 extends or retracts, the abutment plate 114 applies pressure to the bottom of the syringe 12, thereby squeezing out the oil inside the syringe 12. Alternatively, the first telescopic rod 112 can be replaced by a cylinder, which can also achieve the function of applying pressure to the bottom of the syringe 12.

[0025] Furthermore, the fixing component 113 includes a buckle and a second telescopic rod. The inner side of the buckle is arc-shaped, corresponding to the shape of the outer wall of the syringe 12, and is usually made of an elastic material, such as rubber or plastic. Its inner side abuts against the outer wall of the syringe 12, which can firmly fix the syringe 12. The second telescopic rod can be an electric or hydraulic telescopic rod similar to the first telescopic rod 112, which is set in the base 111 and fixedly connected to the buckle at one end. By extending and retracting the second telescopic rod, the position of the buckle can be adjusted to accommodate syringes 12 of different sizes. The buckle can also be replaced by a clamp, which is fastened by bolts and can also serve to fix the syringe 12.

[0026] Furthermore, the syringe 12 is mounted on the actuator 11, with its injection nozzle 121 connected to one end of the tubing 13. The tubing 13 is typically made of rubber or plastic, possessing a certain degree of flexibility for easy connection and position adjustment. The other end of the tubing 13 is the injection port 131, located at the oil filling port 3 above the expansion zone of the tank. The injection port 131 is composed of a rigid needle, typically made of stainless steel or other metals, possessing a certain degree of hardness and corrosion resistance. The rigid needle is sealed to the tubing 13 via a connector, which can be a threaded connector or a quick connector, ensuring a tight seal. The rigid needle is clamped and moved by the three-axis fine-tuning platform 2.

[0027] The fixing assembly 113 first fixes the syringe 12 to the actuator 11. Then, the first telescopic rod 112 applies pressure to the bottom of the syringe 12 through the abutment plate 114, causing the oil in the syringe 12 to be injected into the tank through the hose 13 and the injection port 131. This combination method can realize intermittent oil injection. By controlling the extension frequency and amplitude of the first telescopic rod 112, the amount of oil injected can be precisely controlled.

[0028] Specifically, refer to Figure 2The three-axis fine-tuning platform 2 includes a lead screw 21, a guide rail 22, a slider 23, and a coupling 24. The lead screw 21 is generally a ball screw, characterized by high precision and efficiency. The guide rail 22 is usually made of metal with a precision-machined surface to ensure smooth sliding of the slider 23. The slider 23 cooperates with the lead screw 21, achieving linear motion through the rotation of the lead screw 21. The coupling 24 connects the lead screw 21 and the servo motor, transmitting power from the servo motor to the lead screw 21.

[0029] Furthermore, refer to Figure 1 The lead screw 21, guide rail 22, slider 23, and coupling 24 form a moving unit. There are three moving units, which are set and connected in the XYZ directions. The coupling 24 of each group is connected to a servo motor. By controlling the rotation of the servo motors of different groups, the injection port 131 can be moved precisely in three directions.

[0030] Furthermore, the three-axis fine-tuning platform 2 is also equipped with grippers 25, which are typically made of metal or plastic and possess a certain degree of elasticity and clamping force. These grippers are used to hold the injection port 131 of the tubing 13. The gripping action of the grippers 25 ensures that the injection port 131 moves stably with the three-axis fine-tuning platform 2. Alternatively, the grippers 25 can be replaced with clamps, which are secured with bolts and also serve the same purpose of holding the injection port 131.

[0031] The three sets of moving units control the movement of the injection port 131 in the X, Y, and Z directions respectively. A servo motor drives the lead screw 21 to rotate, causing the slider 23 to slide on the guide rail 22, thereby achieving precise position adjustment of the injection port 131. This combination method allows for flexible adjustment of the injection port 131's position according to actual needs, improving the accuracy of oil injection.

[0032] The implementation principle of this application embodiment is as follows: intermittent oil injection is achieved through the injection pump 1, which can precisely control the oil injection volume. Simultaneously, the position of the injection port 131 is precisely controlled using the triaxial fine-tuning platform 2, avoiding the problems of inaccurate oil injection position and unstable oil injection volume in traditional oil injection methods. Compared with traditional manual oil injection methods, the accuracy of oil injection is improved, thereby improving the accuracy of powder oil absorption value determination. Furthermore, the system's structural design is reasonable, and the materials and connection methods of each component ensure the system's stability and reliability, reducing the probability of failure, extending the system's service life, and meeting the needs of modern industrial production for efficient and accurate testing.

Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
