Description

Technical Field

[0001] This utility model relates to the technical field of carbon black testing equipment, specifically to an automatic lifting door device for a carbon black iodine absorption value measuring instrument. Background Technology

[0002] Carbon black, as an important industrial raw material, is widely used in various industries such as rubber, plastics, inks, and coatings. Its iodine absorption value is one of the key indicators for evaluating the quality and performance of carbon black. The iodine absorption value reflects the specific surface area and surface activity of carbon black, significantly impacting its performance in various applications. For example, in the rubber industry, carbon black with a high iodine absorption value can impart better reinforcing properties to rubber, effectively improving the strength and abrasion resistance of rubber products. In the ink industry, the iodine absorption value affects the tinting strength and dispersibility of carbon black, thus affecting the printing effect of the ink. Therefore, accurately measuring the iodine absorption value of carbon black is crucial for ensuring product quality, optimizing production processes, and promoting industry development. However, current carbon black iodine absorption value measuring instruments on the market have many structural design flaws, especially in the door design, which severely restricts the user experience and measurement efficiency. Most existing carbon black iodine absorption value measuring instruments use a manually opening and closing door structure, requiring operators to manually open and close the door before and after measurement. In frequent measurement work, manual operation is not only time-consuming and labor-intensive, increasing the workload of operators, but also prone to human error leading to incomplete door closure, affecting the stability of the measurement environment and the accuracy of measurement results. For example, when continuously measuring multiple carbon black samples, operators may fail to fully close the manual door due to fatigue, allowing external dust and other impurities to enter the measuring instrument, interfering with the measurement process and causing deviations in the measurement data. Existing automatic lifting doors mostly use chain drives or ordinary screw-nut drives. After long-term use, chain drives are prone to chain elongation due to wear, leading to unstable operation of the lifting door and even chain derailment, affecting the normal use of the instrument. Furthermore, chain maintenance and replacement are costly, requiring regular lubrication, increasing maintenance workload. While ordinary screw-nut drives are relatively simple in structure, their transmission efficiency is low, consuming a lot of energy during frequent opening and closing of the lifting door. Simultaneously, the friction between the nut and the screw is high, easily causing wear on components and shortening service life. Therefore, this utility model provides an automatic lifting door device for a carbon black iodine absorption value measuring instrument to address the shortcomings of existing technologies. Summary of the Invention

[0003] This utility model addresses the aforementioned shortcomings of existing technologies by providing an automatic lifting door device for a carbon black iodine absorption value measuring instrument. It includes: a lifting door device, a through-type lead screw stepper motor, a driver, and lifting / lowering door buttons. The lifting door device comprises: a door, an inner lining, and a slide rail.

[0004] The inner lining is installed and fixed on the main body of the carbon black iodine absorption value tester, serving to fix and support it. It provides a mounting base for components such as slide rails and through-type lead screw stepper motors, and firmly connects these components to the main body of the carbon black iodine absorption value tester, ensuring the structural stability and integrity of the entire automatic lifting door device and the main body of the measuring instrument.

[0005] The slide rails are installed on both sides of the inner lining to provide precise guidance for the up and down sliding of the valve, enabling the valve to run smoothly along the fixed track. This effectively prevents the valve from shaking or deviating during the lifting and lowering process, ensuring the smoothness and reliability of the valve's opening and closing action. At the same time, it can also reduce friction between the valve and other components to a certain extent.

[0006] The valve is mounted on the liner via a slide rail. As one of the core components of the device, the valve is a key component for switching between the sealed and open states of the measuring instrument. During measurement, when the valve is closed, it isolates the inside of the measuring instrument from the external environment, preventing dust and other external impurities from entering the instrument and maintaining the stability of the measurement environment, thus providing a reliable guarantee for accurate measurement of the iodine absorption value of carbon black. When it is necessary to place or remove the carbon black sample, the valve opens to facilitate the relevant operations by the operator.

[0007] The valve, lining, and slide rail work together to form a lifting door device.

[0008] The through-type lead screw stepper motor is mounted on the inner liner, while the lead screw is installed at both ends of the valve. The through-type lead screw stepper motor is the power source for the automatic lifting and lowering of the valve. After receiving the electrical signal transmitted by the driver, the motor can rotate precisely according to predetermined instructions. The lead screw converts the rotational motion of the motor into linear motion, thereby driving the valve to rise and fall along the slide rail. Due to the through-type design, the lead screw is directly connected to the upper and lower ends of the valve, reducing transmission links and improving transmission efficiency and control precision. Compared with traditional transmission methods, it can more accurately control the lifting position and speed of the valve.

[0009] The driver connects the through-type lead screw stepper motor to the lifting and lowering door button. The driver is a bridge connecting the through-type lead screw stepper motor and the lifting and lowering door button. It can process and amplify the operation signal from the lifting and lowering door button, and transmit the appropriate electrical signal to the motor to control the motor's start, stop, forward rotation, reverse rotation and speed, thereby achieving precise control of the door's lifting and lowering action.

[0010] The door raising and lowering buttons serve as human-machine interface components, acting as the entry point for operators to issue control commands. By pressing the door raising or lowering button, operators send corresponding operation signals to the actuator, thereby controlling the door's raising and lowering actions. The operation is simple and intuitive, greatly reducing the workload of operators.

[0011] Compared with existing technologies, the automatic lifting door device of this carbon black iodine absorption value measuring instrument can better meet the needs of carbon black testing and provide efficient, stable and reliable technical support for carbon black quality testing.

[0017] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. The present invention is not limited to the specific embodiments disclosed below.

[0018] First, securely install the inner liner 11 onto the main body of the carbon black iodine absorption value analyzer using bolts, ensuring a tight connection between the inner liner 11 and the analyzer body without any shaking or displacement, thus laying a solid foundation for the installation of subsequent components. Next, install the two slide rails 12 on both sides of the inner liner 11, ensuring that the slide rails 12 fit tightly against the inner liner 11 and that the two slide rails 12 are parallel. After completing the installation of the inner liner 11 and slide rails 12, assemble the valve 10 to the inner liner 11 via the slide rails 12 on both sides, allowing the valve 10 to slide freely along the slide rails 12. During assembly, a small amount of lubricant can be applied to the surface of the slide rails 12 to further reduce friction between the valve 10 and the slide rails 12, improving the smoothness of the valve 10's lifting and lowering.

[0019] Next, the through-type lead screw stepper motor 2 is installed. The stepper motor 20 is fixedly installed on the inner liner 11 at the pre-set installation position, ensuring that the stepper motor 20 is firmly installed and will not loosen due to vibration generated by the motor operation. At the same time, both ends of the lead screw 21 are connected to the upper and lower ends of the valve 10 respectively. The connection method is a threaded connection, ensuring that the connection between the lead screw 21 and the valve 10 is tight, so that the lead screw 21 can effectively drive the valve 10 to move up and down.

[0020] When installing driver 3, place it in a location that facilitates operation and maintenance, and connect driver 3 to stepper motor 20 of through-type lead screw stepper motor 2, door raising button 4, and door lowering button 5 via wires. During the connection process, it is essential to strictly follow the electrical wiring diagram to ensure correct wiring and avoid malfunctions or safety hazards caused by incorrect wiring.

[0021] Once the device is installed and inspected, it can be put into use. When a door-raising operation is required, the operator presses the door-raising button 4. The operation signal from the door-raising button 4 is transmitted to the driver 3. When the driver 3 receives the operation signal from the door-raising button 4, it processes the signal and generates a corresponding control pulse sequence, driving the stepper motor 20 to rotate in a preset direction and number of steps. The rotational motion of the rotor inside the stepper motor 20 is converted into linear motion through the lead screw 21 connected to it. Since the lead screw 21 is directly connected to the upper and lower ends of the valve 10, the linear motion of the lead screw 21 will directly and synchronously drive the valve 10 to rise along the slide rail 12 until it reaches the preset position, completing the door-raising operation.

[0022] When a door lowering operation is required, the operator presses the door lowering button 5. Button 5 sends an operation signal to the driver 3. Upon receiving the signal, the driver 3 processes it and generates a corresponding control pulse sequence, controlling the stepper motor 20 to reverse. The rotational motion of the rotor inside the stepper motor 20 is converted into linear motion via the lead screw 21 connected to it. Since the lead screw 21 is directly connected to the upper and lower ends of the valve 10, its linear motion directly and synchronously drives the valve 10 to descend along the slide rail 12 until the valve 10 is completely closed, isolating the measuring instrument from the external environment and completing the door lowering operation.
