Description

Technical Field

[0001] This utility model belongs to the technical field of high-temperature fire-tracing composite materials, and relates to a fire-tracing filament bundle, particularly a biomimetic continuous pendulum machine for fire-tracing long filament bundles. Background Technology

[0002] With the large-scale upgrading of manufacturing industries both domestically and internationally, and considering factors such as energy consumption, manufacturing costs, production efficiency, and the high cost-effectiveness of materials, composite materials that are lightweight, have high strength, and can withstand certain temperatures have become the most sought-after market for both suppliers and consumers.

[0003] The process of creating the calcination filament bundle begins by extruding the wet gel through micropores to obtain continuous filament bundles with diameters in the micrometer range. Under normal temperature and humidity conditions, these wet gel filament bundles will absorb moisture and become sticky, or even melt upon contact with water, in a high-humidity environment, making secondary high-temperature calcination impossible. Therefore, after the rapid and continuous extrusion of the wet gel in large quantities, it is necessary to quickly disperse and collect it. This ensures both uniform dispersion and, under controlled temperature and humidity conditions, a transformation from the wet gel filament bundle state to a dry gel state, reducing its moisture content.

[0004] During high-speed collection, the collection of wet gel must ensure low curvature, and sharp angles or bends are not allowed. The wet gel should be in a large arc shape. This large arc shape is maintained after it becomes dry gel, and it will also maintain its large arc shape after calcination. Considering that this type of flaming filament bundle has high brittleness, the large arc is a prerequisite for ensuring that it has extremely high strength in the straight direction after sintering. At the same time, considering the high collection speed, the straight direction is theoretically the best. However, it is difficult to achieve equipment that can reach hundreds of meters in length in reality, so the large arc direction is the necessary path. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a biomimetic continuous spherical machine for arson filament bundles. The technical problem this invention aims to solve is: how to achieve arc bending of arson filament bundles without small angles in a wet gel state, and to continuously achieve post-processing.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A biomimetic continuous oscillating machine for fire-tracing filament bundles includes a support platform. Two rotating rods are rotatably connected to the surface of the support platform. The two rotating rods are synchronously driven by a drive motor. Guide wheels are fixedly installed on the outer walls of the two rotating rods. Positioning pins are fixedly connected inside the two guide wheels. Guide arms are rotatably connected to the outer walls of the two positioning pins.

[0008] A compression traction gun is fixedly installed at the end of the guide arm away from the guide wheel, and a receiving unit is provided below the compression traction gun.

[0009] Both rotating rods have a synchronous wheel fixedly installed at their bottom ends, and the synchronous wheel supports the bottom of the platform. The outer wall of the synchronous wheel is engaged with a meshing belt, and the inner side of the meshing belt is also engaged with a drive wheel. The drive wheel is rotatably connected to the bottom of the platform. The top of the drive wheel is fixedly installed with the output shaft of the drive motor, and the drive motor is fixedly installed on the surface of the platform.

[0010] With the above structure, the meshing belt is made of composite material hot-pressed weaving, which ensures high resistance to fatigue wear and plastic deformation. Under the action of the drive wheel and the synchronous wheel, the meshing belt is driven synchronously, ensuring that the two guide wheels rotate synchronously to control one guide arm to make a swinging motion. At the same time, the guide arm has good rigidity and resistance to tensile and compressive stress fracture, ensuring the swinging effect of the guide arm driving the compression traction gun.

[0011] The receiving unit includes a drive roller, one end of which is connected to an external motor. A transmission belt is engaged with the outer wall of the drive roller, and a driven roller is engaged with the inner wall of the other side of the transmission belt.

[0012] With the above structure, the external motor is a variable frequency motor, which can adjust the speed of the transmission belt. The speed of the transmission belt can be controlled according to requirements. If the density of the filament bundle is required to be tight, the speed of the transmission belt will be slowed down, and vice versa.

[0013] The transmission belt is located below the compression traction gun, and the transmission belt is a wear-resistant woven mesh belt with a hole diameter of 1mm.

[0014] The above structure, using a woven mesh belt, ensures ventilation and breathability of the transmission belt, improves the cooling effect of the tracing wire bundle, and prevents adhesion.

[0015] One side of the compression traction gun is connected to a compressed air inlet pipe, and the pressure of the compressed air inlet pipe is controlled by a pressure regulating valve, and the compressed air pressure is 0.03 MPa.

[0016] With the above structure, under the pressure control of the regulating valve, the speed of the tracing wire bundle under the acceleration of the airflow can be controlled to ≤200m / min. Moreover, the inner side of the compression traction gun is provided with an annular airflow distribution channel, and the jet holes at the end of the airflow are evenly arranged and facing downwards. In this way, a negative pressure state is formed at a certain distance above the jet port. When the tracing wire bundle falls to the position of the negative pressure chamber, it is instantly pulled down by the airflow.

[0017] The top of the compression traction gun has a feed port, which is polished with an arc.

[0018] Using the above structure, a zirconia ceramic ring is used at the arc-shaped feed inlet position, with a finely polished surface. Since the tracing wire bundle at this position is still in a wet gel state, its strength is not high and it is easily damaged by friction. Therefore, the feed inlet position of the traction gun needs to be finely processed.

[0019] The drive motor is a servo motor.

[0020] With the above structure, after the filament passes through the traction gun, it is required to fall vertically at a speed equal to the nominal linear velocity of the guide wheel under the acceleration of the airflow. This requires precision transmission, so a servo motor must be used for drive. Variable frequency motors or ordinary uncontrolled motors are not allowed. Moreover, this transmission is a flexible transmission, so rapid start-up is not allowed, and free stopping is required. Therefore, the motor transmission system is not allowed to have a braking system.

[0021] Compared with the prior art, the biomimetic continuous oscillating machine for arsonist filament bundles of this invention has the following advantages:

[0022] 1. In this utility model, two guide wheels are used to control one guide arm to perform a pendulum motion, realizing the continuous pendulum motion of the two guide wheels and one guide arm. The work is similar to that of a human arm. The circular motion of the guide arm requires compressed air to be introduced into the end of the guide arm as the source of kinetic energy for the airflow acceleration of the tracing wire bundle. The compressed air path is set on the guide arm, similar to the blood vessels and nerves of a human arm. Moreover, the guide arm is supported by two guide wheels in a suspended state, avoiding the problem of the compressed air path and the tracing wire bundle getting entangled due to the upper or lower support of the shaft. At the same time, it takes into account the biomimetic principle and completely eliminates the problem of entanglement of the tracing wire bundle. Through this setting, the tracing wire bundle can achieve free tension without small-angle arc bending in the wet gel state, and continuous post-processing can be achieved, which greatly improves the strength of the tracing wire bundle.

[0023] 2. In this utility model, the synchronization of the two guide wheels is ensured by the transmission connection between the two guide wheels, realizing the circular motion of the guide arm and the torque transmission between the two sets of common rail guide wheels, which is biomimetic to the inertial drive of human joints. Moreover, by connecting the guide arm and the guide wheel with the positioning pin, which is biomimetic to the elbow joint of the human body, when the two guide wheels make self-rotational motion, the self-rotational motion of the positioning pin is equivalent to the guide arm making planetary motion, which facilitates the support of the guide arm to make continuous circular motion.

[0033] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0034] Example

[0035] like Figures 1-7 As shown;

[0036] A biomimetic continuous oscillating machine for flaming filament bundles includes a support platform 1, rotating rods 2, guide wheels 3, positioning pins 4, guide arms 5, compression traction guns 6, driving rollers 7, driven rollers 8, transmission belts 9, synchronous pulleys 10, drive wheels 11, meshing belts 12, and a drive motor 13. The support platform 1 is made of thickened forged cold-rolled plate with a thickness of 10mm. The overall mounting and positioning holes are pre-machined using a machining center. Specifically, two rotating rods 2 are rotatably connected to the surface of the support platform 1. The two rotating rods 2 are synchronously driven by the drive motor 13, which is a servo motor. The bottom ends of both rotating rods 2 are fixedly mounted with synchronous pulleys 10, which are located below the support platform 1. The outer wall of the synchronous pulley 10 is meshed with the meshing belt 12, and the inner side of the meshing belt 12 is also meshed with the drive wheel. 11. The drive wheel 11 is rotatably connected to the bottom of the support platform 1. The top of the drive wheel 11 is fixedly mounted with the output shaft of the drive motor 13, and the drive motor 13 is fixedly mounted on the surface of the support platform 1. The servo motor is controlled by a three-phase power supply to facilitate power stability. Since this transmission is a flexible transmission, rapid start-up is not allowed, and free stopping is required. Therefore, the motor transmission system is not allowed to have a braking system. After the wire bundle passes through the compression traction gun 6, under the acceleration of the airflow, the vertical falling speed is required to be equal to the nominal linear speed of the guide wheel 3. Corresponding to this precision transmission, a servo motor must be used for drive. Variable frequency motors or ordinary uncontrolled motors are not allowed. At the same time, considering the large torque at high speed, a series reducer with a speed ratio of 20:1 can be used to protect the motor and prevent overheating.

[0037] To achieve a circular motion effect during filament collection, guide wheels 3 are fixedly installed on the outer walls of both rotating rods 2. The two guide wheels 3 are mirror-machined, and locating pins 4 are fixedly connected inside each guide wheel 3. Guide arms 5 are rotatably connected to the outer walls of the two locating pins 4. This arrangement provides rigid support for rotation between the guide wheels 3 and the guide arms 5. The locating pins 4 are machined to a precision of 0.01mm, ideally supporting the guide arms 5 in continuous circular motion. The circular motion of the guide arms 5 and the torque transmission between the two sets of guide wheels 3 mimic the inertial drive of a human joint. Simultaneously, the locating pins 4 between the guide arms 5 and the guide wheels 3 mimic the elbow joint of a human. When the two sets of guide wheels 3 rotate, the guide arms 5 are connected by a locating pin 4. The self-rotation of pin 4 is equivalent to the planetary motion of guide arm 5. Furthermore, a compression traction gun 6 is fixedly installed at the end of guide arm 5 away from guide wheel 3. A compressed air inlet pipe is connected to one side of the compression traction gun 6, and the pressure of the compressed air inlet pipe is controlled by a pressure regulating valve. A feed port is opened at the top of the compression traction gun 6, and the feed port is finished with an arc polishing process. Based on the actual tracing wire traction speed v = 100–160 m / min, the nominal diameter of guide wheel 3 is initially designed to be D = 310 mm. Based on the linear velocity v = nπD, the angular velocity is controlled between 97 and 156 r / min. The nominal diameter of 310 mm is also the diameter of the tracing wire bundle produced by the circling machine, achieving a high degree of arc development. Furthermore, the guide wheel 3 is made of lightweight aluminum. Based on the differential momentum p = MVσ = MnπD, reducing the mass of the guide wheel 3 while maintaining the total momentum allows for a proportional increase in linear velocity. Simultaneously, machining the guide wheel 3 into a hollow frame also achieves lower momentum or inertia, maintaining a higher linear velocity and thus improving its sensitivity during start-up, stopping, or acceleration. While the guide wheel 3 rotates, a guide arm 5 is controlled to perform a pendulum motion. Based on the fundamental geometric theorem that two points in the same plane determine a straight line, the straight line is cut into modifiable segments, thus determining the arm length of the guide arm 5. The pendulum trajectory is entirely equal to the nominal diameter of the guide wheel 3. Simultaneously, the guide arm 5 continuously... In the pendulum motion, there is a strict range control between the linear velocity of the compression traction gun 6 and the guide arm 5 in the circular motion, and there is also a strict range control between the downward jet velocity of the compressed air and the falling velocity of the tracing wire bundle. When the airflow is large enough, the vertical linear velocity V1 generated is equal to the air jet velocity V2. The distance between the compression traction gun 6 and the transmission belt 9 is S1 = V1 * t. The stroke considered here is about 500 mm. The acceleration generated by free fall is not considered. Only the product of the linear velocity generated by the tracing wire bundle and the falling time is calculated. According to the same actual t, the compression traction gun 6 of the guide arm 5 is in circular motion, and its stroke is S2 = V3 * t = nπDt. When V1 = V3, the ideal state is reached.

[0038] Furthermore, to achieve precise traction of the compression traction gun 6, an annular airflow distribution channel is provided on the inner side of the compression traction gun 6. A ring of airflow end-spray holes are evenly arranged and face downwards. This creates a negative pressure state at a certain distance above the spray nozzle. When the tracing wire bundle falls into the negative pressure chamber, it is instantly drawn down by the airflow. The traction speed V2 is controlled by the pressure regulating valve to ensure V1 = V2. Since the tracing wire bundle at this location is still in a wet gel state, its strength is low and it is easily damaged by friction. Therefore, the feed port of the traction gun is polished with an arc. The material can be made of... The device uses a zirconia ceramic ring with a finely polished surface, which is wear-resistant and self-lubricating. At the same time, a receiving unit is set below the compression traction gun 6. Specifically, the receiving unit includes a drive roller 7, and one end of the drive roller 7 is connected to an external motor. The external motor is a variable frequency motor, which can control the forward speed of the transmission belt 9 according to the speed of the filament collection. Specifically, the transmission belt 9 is meshed with the outer wall of the drive roller 7, and the driven roller 8 is meshed with the inner wall of the other side of the transmission belt 9. The transmission belt 9 is located below the compression traction gun 6. The transmission belt 9 is a mesh belt made of wear-resistant material with a mesh diameter of 1mm to ensure ventilation and breathability of the transmission belt 9.

[0039] The working principle of this utility model is as follows: During operation, the drive motor 13 is energized to drive the drive wheel 11 to rotate. Under the action of the meshing belt 12, the two guide wheels 3 rotate synchronously, causing the two guide wheels 3 to drive the guide arm 5 to make a circular motion along the same track. This causes the arsenic filament bundle to fall onto the transmission belt 9 along with the compressed airflow after being pulled to the compression traction gun 6. At the same time, as the guide wheel 3 makes a circular motion, the guide arm 5 also makes a circular motion with the compression traction gun 6 at the same diameter and speed. In this way, the arsenic filament bundle is placed on the transmission belt 9 at a uniform speed along with the compression traction gun 6. As the transmission belt 9 moves forward under the rotation of the drive roller 7, the filament bundle is collected evenly. This realizes the requirement of free tension and no small-angle arc bending of the arsenic filament bundle in the wet gel state, and continuous post-processing is achieved, which greatly improves the strength of the arsenic filament bundle.

[0040] like Figures 6-7 As shown, in actual operation, through experimental comparison, the use of a biomimetic continuous pendulum machine to collect the tracing wire bundle in a pendulum manner has a very significant improvement in the collection effect of the tracing wire bundle, with improvements in diameter, strength, and draw and twisting.
