Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of material conveying, and in particular to a carbon black weighing and feeding device. Background Technology
[0002] In the production of aircraft tires, raw materials such as rubber and carbon black need to be added to an internal mixer for internal mixing. Before adding carbon black to the mixer, a weighing device is required to quantitatively weigh the carbon black. A feeding device is then used to add the carbon black to the weighing device during quantitative weighing. In the prior art, a utility model patent with patent application number 202023148458.1 discloses a carbon black feeding device, which mainly consists of a hopper and rollers. During use, carbon black particles are added to the rollers through the hopper, and the rotation of the rollers transports the carbon black particles. However, this device has the following problems: due to its extremely high specific surface area and rich microporous structure, carbon black easily absorbs moisture from the air. During movement or storage, the carbon black particles with absorbed moisture are easily compressed into clumps. Large clumps of carbon black are inconvenient to mix in the internal mixer, affecting the mixing effect. Therefore, a weighing and feeding device that can break up clumps of carbon black is needed. Utility Model Content
[0003] To solve the above-mentioned technical problems, this utility model provides a carbon black weighing and feeding device that can not only transport carbon black particles, but also crush agglomerated carbon black particles, making it convenient to add carbon black particles to the internal mixer for internal mixing. It is easy to use, reliable and practical.
[0004] This utility model discloses a carbon black weighing and feeding device, comprising a base plate, an electronic scale, and a cylinder. The electronic scale is mounted on the base plate, and the cylinder is placed on the weighing end of the electronic scale. It also includes a screw conveyor, a feed hopper, a conveying mechanism, and a crushing mechanism. The screw conveyor is inclinedly mounted on the base plate, with its output end located above the cylinder. The input end of the screw conveyor is equipped with a feed hopper. The crushing mechanism is mounted on the base plate and has a crushing function. The conveying mechanism has a material conveying function. When weighing and feeding carbon black particles, the carbon black particles are first added to the crushing mechanism. The crushing mechanism then breaks up large clumps of carbon black into smaller particles. These smaller particles are then conveyed to the screw conveyor via the conveying mechanism, and finally fed into the cylinder via the screw conveyor. Simultaneously, the carbon black particles in the cylinder are weighed by the electronic scale. This device not only conveys carbon black particles but also crushes clumps of carbon black, facilitating the addition of carbon black particles to the internal mixer for internal mixing. It is convenient to use and has high reliability and practicality.
[0005] Preferably, the crushing mechanism includes a crushing cylinder, a support, a breaking mechanism, a guiding mechanism, and a transfer mechanism. The crushing cylinder is fixedly mounted on the base plate by the support. A chamber is provided inside the crushing cylinder, and multiple through holes communicating with the chamber are provided at the bottom of the crushing cylinder. The breaking mechanism is mounted on the base plate and the crushing cylinder and has a crushing function. The guiding mechanism is located below the crushing cylinder and has a guiding function. The transfer mechanism is located below the guiding mechanism and has a transfer function. When feeding crushed carbon black particles, the carbon black particles are first added into the crushing cylinder chamber. Then, the carbon black particles fall through the through holes at the bottom of the crushing cylinder onto the guiding mechanism, and then through the guiding mechanism onto the transfer mechanism for transport to the screw conveyor. When the carbon black particles contain agglomerated particles, the breaking mechanism is opened to break the agglomerated particles into smaller particles. The smaller carbon black particles are discharged through the through holes at the bottom of the crushing cylinder and fall onto the guiding mechanism for continued transport, facilitating the crushing of agglomerated carbon black.
[0006] Preferably, the crushing mechanism includes a fixed frame, a drive motor, a rotating shaft, a base, and multiple crushing rods. The fixed frame is fixedly mounted on the base plate, and the drive motor and the base are both fixedly mounted on the upper end of the fixed frame. The output end of the drive motor is provided with a rotating shaft, which is rotatably mounted on the base and the crushing cylinder. The multiple crushing rods are all fixedly mounted on the rotating shaft and are located in the chamber of the crushing cylinder. When the drive motor is turned on, the drive motor causes the multiple crushing rods to rotate through the rotating shaft. During the rotation, the multiple crushing rods crush the agglomerated carbon black particles in the chamber of the crushing cylinder, thus facilitating the crushing of carbon black particles.
[0007] Preferably, the guiding mechanism includes multiple fixed columns, multiple sliding columns, a spring, a guide platform, and a vibration motor. The fixed columns are all fixedly mounted on the base plate. The lower parts of the sliding columns are slidably mounted on the fixed columns. The lower end of the spring is fixedly mounted on the base plate. The guide platform is fixedly mounted on the upper ends of the spring and sliding columns. The upper end of the guide platform is an inclined surface. The guide platform is located below the crushing cylinder. The vibration motor is fixedly mounted on the guide platform. When the carbon black particles are discharged through the through-hole at the bottom of the crushing cylinder, the carbon black particles fall onto the upper end of the guide platform. Then, the carbon black particles slide down the upper end of the guide platform into the transfer mechanism. Simultaneously, the vibration motor is activated. The inertial force generated by the vibration motor during operation drives the guide platform to vibrate up and down, preventing carbon black particles from adhering to the upper end of the guide platform.
[0008] Preferably, the transfer mechanism includes a transfer cylinder, a servo motor, a rotating shaft, a vacuum grain suction machine, and a conveying pipe. The transfer cylinder is fixedly mounted on a base plate, and the servo motor is fixedly mounted on the transfer cylinder. A cavity is provided inside the transfer cylinder, and the upper end of the transfer cylinder is open. The transfer cylinder is located below the front end of the guide platform. The rotating shaft is rotatably mounted on the transfer cylinder, and the power output end of the servo motor is connected to the rotating shaft. Spiral blades are provided on the rotating shaft. The input end of the vacuum grain suction machine is connected to the right side of the cavity in the transfer cylinder through the conveying pipe, and the output end of the vacuum grain suction machine is located above the feed hopper. The vacuum grain suction machine is fixedly mounted on a support frame in the workshop. When the carbon black particles fall into the transfer cylinder via the guide platform, the servo motor is turned on, driving the rotating shaft to rotate, which in turn causes the spiral blades on the rotating shaft to rotate, causing the carbon black particles in the transfer cylinder to be conveyed closer to the conveying pipe. Then, the vacuum grain suction machine is turned on, allowing the carbon black particles in the transfer cylinder to be sucked in by the vacuum grain suction machine and discharged into the feed hopper. The carbon black particles then fall into the screw conveyor via the feed hopper for further conveying. This facilitates the transfer of carbon black particles.
[0009] Preferably, baffles are provided at both ends of the guide platform; this prevents carbon black particles from falling off the upper part of the guide platform.
[0010] Preferably, the drive motor is equipped with a leakage current protector.
[0011] Preferably, the pulverizing cylinder is provided with a transparent observation window; this feature facilitates the observation of the pulverization state of the carbon black particles in the pulverizing cylinder by the staff.
[0012] Compared with the prior art, the advantages of this utility model are: it can not only transport carbon black particles, but also crush agglomerated carbon black particles, which facilitates the addition of carbon black particles to the internal mixer for internal mixing. It is convenient to use and has high reliability and practicality. Attached Figure Description

The crushing mechanism is installed on the base plate 1 and has a crushing function. The conveying mechanism has a material conveying function. The device is used for weighing and feeding carbon black particles. When feeding carbon black granules by weighing, the carbon black granules are first added to the crushing mechanism. Then, the crushing mechanism breaks down the large clumps of carbon black granules into small granules. The small carbon black granules are then conveyed to the screw conveyor 4 by the conveying mechanism. The screw conveyor 4 then conveys the carbon black granules into the cylinder 3. At the same time, the carbon black granules in the cylinder 3 are weighed by the electronic scale 2. This system can not only convey carbon black granules but also crush clumps of carbon black granules, making it convenient for adding carbon black granules to the internal mixer for internal mixing. It is easy to use and has high reliability and practicality.
[0022] like Figure 1 and Figure 3The crushing mechanism includes a crushing cylinder 7, a support 8, a breaking mechanism, a guiding mechanism, and a transfer mechanism. The crushing cylinder 7 is fixedly installed on the base plate 1 via the support 8.

The breaking mechanism is installed on the base plate 1 and the crushing cylinder 7 and has the function of crushing. The guiding mechanism is located below the crushing cylinder 7 and has the function of guiding. The transfer mechanism is located below the guiding mechanism and has the function of transferring. When feeding carbon black particles, the carbon black particles are first added into the chamber of the crushing cylinder 7. Then, the carbon black particles fall onto the guiding mechanism through the through holes at the bottom of the crushing cylinder 7. After that, the carbon black particles fall onto the transfer mechanism through the guiding mechanism and are transferred to the screw conveyor 4 for conveying. When there are agglomerated particles mixed in with the carbon black particles, the breaking mechanism is opened, and the agglomerated particles are broken into small particles. The small carbon black particles are discharged through the through holes at the bottom of the crushing cylinder 7 and fall onto the guiding mechanism for continued conveying, which facilitates the crushing of agglomerated carbon black.

The output end of the drive motor 11 is provided with a rotating shaft 12. The rotating shaft 12 is rotatably installed on the base 13 and the crushing cylinder 7. Multiple crushing rods 14 are all fixedly installed on the rotating shaft 12. Multiple crushing rods 14 are all located in the chamber of the crushing cylinder 7.

The upper end of the guide platform 18 is an inclined surface. The guide platform 18 is located below the crushing cylinder 7. The vibration motor 19 is fixedly mounted on the guide platform 18. When the carbon black particles are discharged through the through hole at the bottom of the crushing cylinder 7, the carbon black particles fall onto the upper end of the guide platform 18. Then, the carbon black particles slide down through the upper end of the guide platform 18 into the transfer mechanism. Simultaneously, the vibration motor 19 is turned on. The inertial force generated by the vibration motor 19 during operation drives the guide platform 18 to vibrate up and down, preventing carbon black particles from adhering to the upper end of the guide platform 18.

The output end is located above the feed hopper 5; the vacuum grain suction machine 23 is fixedly installed on the support frame of the workshop; after the carbon black particles fall into the transfer cylinder 20 through the guide table 18, the servo motor 21 is turned on, the servo motor 21 drives the rotating shaft 22 to rotate, and then the spiral blades on the rotating shaft 22 rotate, so that the carbon black particles in the transfer cylinder 20 are transported to a position close to the conveying pipe 24. Then the vacuum grain suction machine 23 is turned on, so that the carbon black particles in the transfer cylinder 20 are sucked in by the vacuum grain suction machine 23 and discharged into the feed hopper 5.
