Description

Technical Field

[0001] The present invention relates to an insulating material preparation device for electrical equipment and a preparation method thereof, belonging to the technical field of insulating material preparation. Background Art

[0002] In the preparation of insulation materials for electrical equipment, traditional equipment typically uses a single stirring device to mix and knead the materials. However, this traditional equipment has some obvious technical problems, especially in terms of material mixing uniformity, heating effect, and bubble elimination.

[0003] The generation of bubbles in existing equipment's stirring systems during the preparation of insulating materials is inevitable, especially during the mixing process. These stirring systems often fail to effectively eliminate and suppress bubble formation in the mixture, relying solely on vacuum equipment to remove bubbles. This process is not only time-consuming, but also, if time is shortened to maximize efficiency, bubbles may remain, compromising the final material's density and insulation performance.

[0004] Therefore, the technical problem to be solved by this scheme is how to effectively eliminate bubbles and reduce the generation of bubbles during the preparation of high-voltage insulating materials such as silicone rubber self-adhesive tapes, reduce the time it takes for vacuum equipment to remove bubbles, and improve production efficiency and product quality.

[0026] As a further improvement, the power connection mechanism includes a first gear welded and fixed to the rotating shaft, and the kit is located below the first gear;

[0027] A second gear is mounted on the outer ring surface of the multi-stage piston rod, which matches the height of the first gear. A strong magnet is embedded and fixed under the second gear. The multi-stage piston rod is driven toward the rotating shaft by the second driving mechanism, and the first gear is meshed with the second gear.

[0032] The beneficial effects of the present invention are:

[0033] The present invention is capable of accurately controlling the feeding time and sequence of each material by providing multiple feeding ports and corresponding feeding switches, ensuring that different types of materials enter the barrel accurately in proportion and sequence, thereby achieving uniform mixing. The use of a stirring and kneading component in conjunction with a vibration component can not only quickly and evenly stir the material, but also effectively eliminate and reduce bubbles in the mixture through vibration, thereby avoiding the impact of bubbles on the performance of the insulating material. Especially in the later stage of mixing, the heating component is wrapped around the outside of the barrel to fully heat the mixed material and maintain the flow state of the mixed material. The heating temperature is accurately adjusted by the control module to ensure that the material can be evenly heated during the heating process, thereby improving the overall quality of the insulating material. The control module accurately controls the switch opening time of the discharge port, and in conjunction with the work of the heating component, the mixed material can be smoothly discharged at the right time to ensure the fluidity and consistency of the material.

[0034] To improve the efficiency, uniformity, and flexibility of the stirring and mixing process, a rotating frame is used as the core component of the stirring and kneading assembly. Its main function is to provide support and realize the basic movement of material mixing. The mixing rods are slidably installed on both ends of the rotating frame through strip-shaped through-holes, and the intensity and range of stirring can be flexibly adjusted according to the type of material and mixing needs. The sliding setting of the mixing rod ensures that it can move freely inside the barrel. As the viscosity of the material changes, the position of the two mixing rods can be adaptively adjusted during rotation according to the viscosity of the material. For example, the initial position is at the edge and gradually moves towards the center as the viscosity increases. This allows the material to be fully kneaded and stirred, avoiding the formation of dead corners.

[0035] In order to realize two different working modes of rotation of the rotating frame and the mixing rod in the stirring and kneading component, the kinetic energy is switched through a kinetic energy connection component. Specifically, the first gear is welded and fixed to the rotating shaft and meshed with the second gear. The second gear is installed on the outer ring surface of the multi-stage piston rod. The kinetic energy is converted by the cooperation of the two gears. At the same time, by setting the cooperation between the strong magnet set on the first gear and the kit, the rotating frame is controlled to achieve power disengagement. The main strong magnet approaches the kit, and the kit moves upward by magnetic attraction, controlling the first groove to disengage from the first protrusion.

[0036] Compared with traditional barrels, multi-dimensional stirring and kneading, combined with vibration components and heating components, can fully eliminate bubbles in the material, improve the density and quality consistency of the material, especially when dealing with highly viscous or difficult-to-mix materials, the advantages are particularly obvious.

Therefore, a feature specified as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0050] Reference Figure 1-8 As shown, an apparatus for preparing insulating material for electrical equipment comprises: a barrel 1, a stirring and kneading assembly 2 is provided in the barrel 1, and a vibration assembly 10 is installed on the stirring and kneading assembly 2;

[0051] Multiple groups of feeding ports 11 are provided on the side of the barrel 1, and each feeding port 11 is provided with a feeding switch 12;

[0052] An output port 13 is provided below the barrel 1, a heating assembly 9 is provided on the outer side of the barrel 1 and covers the output port 13, and a discharge switch 14 is provided at the output port 13;

[0053] A control module 3, wherein the control module 3 is electrically connected to the stirring and kneading component 2, the feed switch 12, the discharge switch 14, the heating component 9, and the vibration component 10;

[0054] The control module 3 controls the opening time and sequence of the multiple feed switches 12, and multiple materials enter the barrel 1 through the corresponding feed ports 11;

[0055] The control module 3 drives the stirring and kneading component 2 to perform preliminary stirring on the materials to mix the materials;

[0056] The control module 3 synchronously drives the heating component 9 to heat the material in the barrel 1;

[0057] The control module 3 drives the stirring and kneading component 2 to knead and stir the material, and cooperates with the vibration component 10 to vibrate the material to eliminate bubbles;

[0058] The control module 3 controls the opening time of the discharge switch 14 , cooperates with the heating component 9 to keep working, and discharges the material through the output port 13 .

[0059] By setting up multiple feeding ports 11 and corresponding feeding switches 12, the feeding time and order of each material can be accurately controlled to ensure that different types of materials enter the barrel 1 accurately in proportion and order, thereby achieving uniform mixing. The use of a stirring and kneading component 2 and a vibration component 10 can not only quickly and evenly stir the material, but also effectively eliminate and reduce bubbles in the mixture through vibration, thereby avoiding the impact of bubbles on the performance of the insulating material. Especially in the later stage of mixing, the heating component 9 is wrapped around the outside of the barrel 1 to fully heat the mixed material and maintain the flow state of the mixed material. The heating temperature is accurately adjusted by the control module 3 to ensure that the material can be evenly heated during the heating process, thereby improving the overall quality of the insulating material. The control module 3 accurately controls the opening and closing time of the discharge port, and cooperates with the work of the heating component 9 to discharge the mixed material smoothly at the right time, ensuring the fluidity and consistency of the material.

[0060] In order to improve the efficiency, uniformity and flexibility of the stirring and mixing process, the stirring and kneading assembly 2 includes a rotating frame 21 rotatably mounted inside the barrel 1, and a group of mixing rods 23 slidably mounted at both ends of the rotating frame 21. The rotating frame 21 is provided with a strip-shaped through hole 22, and the mixing rods 23 are movably inserted into the strip-shaped through hole 22;

[0061] The driving assembly includes a first driving mechanism 4 for driving the rotating frame 21 to rotate, a power connection mechanism 5 for driving the two mixing rods 23 to rotate, a second driving mechanism 6 for controlling the left / right movement of the power connection mechanism 5, and a docking mechanism 7 for controlling the docking / separation between the power connection mechanism 5 and the mixing rods 23;

[0062] It also includes a visual positioning module 8, and the control module 3 is electrically connected to the visual positioning module 8, the first driving mechanism 4, the power connection mechanism 5, the second driving mechanism 6, and the docking mechanism 7;

[0063] The feeding port 11 feeds a variety of materials into the barrel 1, and the control module 3 controls the first driving mechanism 4 to drive the rotating frame 21 to drive the mixing rod 23 to stir the materials for preliminary mixing;

[0064] The control module 3 and the visual positioning module 8 control the second driving mechanism 6 to laterally drive the power connection mechanism 5 to move leftward / rightward to just above the mixing rod 23, and cooperate with the driving of the docking mechanism 7 to connect the mixing rod 23 with the power connection mechanism 5. The second driving assembly drives the power connection mechanism 5 to connect with the first driving mechanism 4 for power connection, and the two mixing rods 23 are controlled to engage and rotate by the connection power.

[0065] The rotating frame 21 is used as the core component of the stirring and kneading assembly 2. Its main function is to provide support and realize the basic movement of material stirring. The mixing rod 23 is slidably installed at both ends of the rotating frame 21 through the strip-shaped through-hole 22. The stirring force and range can be flexibly adjusted according to the type of material and the need for mixing. The sliding setting of the mixing rod 23 ensures that it can move freely inside the barrel 1, and as the viscosity of the material changes, the position of the two mixing rods 23 can be adaptively adjusted according to the viscosity of the material during the rotation process. For example, the initial position is at the edge, and as the viscosity increases, it can gradually move towards the middle. This allows the material to be fully kneaded and stirred, avoiding the generation of dead corners.

[0066] To ensure the installation stability of the mixing rod 23 on the rotating frame 21, the mixing rod 23 includes a main rod 231 and multiple groups of meshing pieces 232 arranged on the outer annular surface of the main rod 231. The meshing pieces 232 on the two mixing rods 23 are arranged alternately. The two mixing rods 23 are close to each other, and the meshing pieces 232 on different mixing rods 23 are engaged with each other.

[0067] A side groove 24 is provided on the inner side wall of the strip-shaped through hole 22 , and a ring piece 233 is welded above the main rod 231 . The ring piece 233 is inserted into the side groove 24 . Through the cooperation between the ring piece 233 and the side groove 24 , the mixing rod 23 is installed on the rotating frame 21 .

[0068] When in use, the ring piece 233 supports the mixing rod 23 . At the same time, some steel balls are embedded under the ring piece 233 to reduce friction when the mixing rod 23 moves laterally on the rotating frame 21 .

[0069] The combination of the strip-shaped through-holes 22 and the sliding mixing rod 23 allows the mixing range and intensity to be adjusted according to the actual needs of the material, thereby ensuring the efficiency of the mixing process and the consistency of the material, and avoiding the uneven mixing of materials in traditional mixing systems.

[0070] The engagement of the power coupling mechanism 5 with the mixing rod 23 is controlled by a second drive mechanism 6. This design allows the stirring device to adjust the rotation mode and speed of the mixing rod 23 as needed. The power coupling mechanism 5 not only transmits driving force to the mixing rod 23 but also ensures the precision of the mixing rod 23's rotation and engagement. The docking mechanism 7 allows the power coupling mechanism 5 to precisely dock and undocking with the mixing rod 23.

[0071] Vision positioning module 8 monitors the position of mixing rod 23 in real time and provides feedback to control module 3, enabling the control system to precisely control the mixing process. The presence of vision positioning module 8 enables the system to automatically calibrate and adjust the device's movements based on actual conditions, ensuring that docking mechanism 7 and mixing rod 23 are properly docked.

[0072] Vision positioning module 8 allows the system to dynamically adjust to the real-time operating status, improving the accuracy and automation of the equipment. Based on the feedback from vision positioning module 8, control module 3 can optimize the motion trajectory of mixing rod 23 to ensure that each mixing process achieves the desired effect.

[0073] The first drive mechanism 4 and the second drive mechanism 6 are used in conjunction to respectively rotate the rotating frame 21 and move the power connection mechanism 5 left and right. This division of labor makes the stirring process more precise, and the synergistic effect of rotation and movement ensures stirring uniformity and flexibility.

[0074] By integrating two independent drive mechanisms, the system provides more precise control over the mixing process. For example, the first drive mechanism 4 independently controls the rotation rate of the rotating frame 21, while the second drive mechanism 6 adjusts the position of the mixing rod 23 as needed. This refined control ensures uniform mixing of the materials, improves work efficiency, and avoids over- or under-mixing.

[0075] This refined, modular design not only enables the equipment to process a wide variety of materials but also significantly improves mixing performance. Precise control of each component ensures more uniform mixing and quickly and effectively eliminates air bubbles, improving final product quality. Furthermore, the system's increased automation reduces the complexity and errors associated with manual operation, ensuring efficient and reliable operation.

[0076] The first driving mechanism 4 includes a first motor 41 mounted above the barrel 1, a rotating shaft 42 is inserted into the output end below the first motor 41, a sleeve 43 is slidably provided below the rotating shaft 42, and a first ridge groove 44 is provided below the sleeve 43;

[0077] A first protrusion 45 corresponding to the first rib groove 44 is provided above the rotating frame 21 . The first rib groove 44 is fitted onto the first protrusion 45 by the downward movement of the sleeve 43 under its own weight.

[0078] During operation, the first drive mechanism 4 drives the rotation of the rotating frame 21 via the first motor 41, which transmits power to the rotating frame 21 via the rotating shaft 42. The design of the sleeve 43 below the rotating shaft 42 and the first rib groove 44 below the sleeve 43 help ensure smooth power transmission and rotational stability. The mating structure of the first rib groove 44 and the first protrusion 45 effectively mechanically guides the movement of the rotating frame 21 stably and precisely. The downward force of the sleeve 43 causes the rib groove to automatically mate with the protrusion, ensuring precise docking without manual operation.

[0079] The coordinated design of the first rib groove 44 and the first protrusion 45 ensures a secure connection between the sleeve 43 and the swing frame 21. The combination of the rib groove and protrusion structure guides and automatically completes docking through its own weight, eliminating the complexity of external operation and enabling quick and stable connection and disconnection. The precise fit between the rib groove and protrusion prevents positional deviation or instability of the swing frame 21 during operation. The relative positioning of the rib groove and protrusion ensures that the swing frame 21 will not experience motion errors due to loosening or misalignment during rotation, thereby achieving precise motion control.

[0080] The weight of the sleeve 43 is used to lower the sleeve 43, ensuring that the sleeve 43 and the first rib 44 can be smoothly and automatically connected. Compared with other methods that require external force or complex mechanical devices, the design simplifies the structure, making the device more reliable and easy to operate.

[0081] In order to ensure that the docking mechanism 7 can be adjusted laterally above the barrel 1 when necessary, the second driving mechanism 6 includes a group of telescopic guide rod motors 61 respectively arranged above the barrel 1, and the output ends of the telescopic guide rod motors 61 are arranged in relative directions, and the output ends are connected to the docking mechanism 7. The telescopic guide rod motor 61 is electrically connected to the control module 3, and the control module 3 controls the telescopic guide rod motor 61 to drive the docking mechanism 7 as a whole to move laterally.

[0082] During operation, the second drive mechanism 6, via a telescopic guide motor 61 positioned above the barrel 1, enables lateral movement of the docking mechanism 7. The output of the telescopic guide motor 61 is connected to the docking mechanism 7, and its lateral movement is controlled by the control module 3. The telescopic guide motor 61 is designed to provide an efficient and precise power source to drive the lateral displacement of the docking mechanism 7. The control module 3 is incorporated to precisely control the motor's movement.

[0083] By using the telescopic guide rod motor 61, power can be effectively transmitted to the docking mechanism 7 and the required lateral movement can be achieved.

[0084] The telescopic guide motor 61 can provide a strong lateral propulsion force, ensuring that the docking mechanism 7 can complete the position adjustment in a short time, improving work efficiency. Through the precise regulation of the motor by the control module 3, the lateral movement of the docking mechanism 7 can be accurately executed, avoiding errors and unnecessary offsets.

[0085] The output ends of the telescopic guide rod motor 61 are arranged in opposite directions, so that the motor can better drive the lateral movement of the docking mechanism 7.

[0086] By arranging the coordinated operation of the telescopic guide rod motor 61 and the control module 3, the second drive mechanism 6 can achieve precise lateral movement of the docking mechanism 7. When the telescopic guide rod motor 61 is fully extended, it precisely cooperates with the power connection mechanism 5, which not only improves the flexibility and operational efficiency of the equipment, but also reduces human error through automatic control, enhancing the stability and reliability of the entire system.

[0087] The docking mechanism 7 includes a cylinder 71 welded to the output end of the telescopic guide rod motor 61, a multi-stage piston rod 72 is rotatably mounted on the lower output end of the cylinder 71, the cylinder 71 is externally connected to a first external air pump, and the first external air pump is electrically connected to the control module 3, and a second protrusion 721 is provided at the end of the multi-stage piston rod 72;

[0088] A second ridge groove 234 that matches the shape of the second protrusion 721 is provided above the mixing rod 23. The control module 3 controls the external air pump to start and cooperate with the cylinder 71 to drive the multi-stage piston rod 72 to extend, so that the second protrusion 721 is inserted into the second ridge groove 234, thereby connecting and fixing the multi-stage piston rod 72 and the mixing rod 23.

[0089] During use, the docking mechanism 7 precisely drives the multi-stage piston rod 72 through the pneumatic cylinder 71 and the multi-stage piston rod 72. A first external air pump connected to the cylinder 71 provides air pressure support. A second bump 721 is provided at the end of the multi-stage piston rod 72, which engages with the second ridge groove 234 on the mixing rod 23 for precise connection. The control module 3 activates the external air pump, regulating the movement of the pneumatic cylinder 71 and the extension of the piston rod to ensure a secure connection. This design, through the action of air pressure, enables fast and stable connection, meeting the precision and force requirements of various operating conditions.

[0090] The use of an air cylinder 71 and multi-stage piston rod 72 eliminates the complex gears and transmissions typically associated with traditional mechanical connections, reducing the complexity of the mechanical structure. The combination of air cylinder 71 and an external air pump provides a significant driving force, ensuring that the multi-stage piston rod 72 can be extended quickly and efficiently, ensuring the connection process is completed efficiently.

[0091] The second protrusion 721 at the end of the multi-stage piston rod 72 engages the second ribbed groove 234 to achieve connection with the mixing rod 23. The key to this design is the interaction between the protrusion and the ribbed groove, which ensures a more stable and precise connection. This ensures that, driven by the cylinder 71, the movement of the piston rod quickly and reliably connects the multi-stage piston rod 72 to the mixing rod 23.

[0092] An external air pump controls the start and stop of cylinder 71 through control module 3. The air pump provides air pressure, pushing the piston rod in cylinder 71 to extend or retract, thereby driving the multi-stage piston rod 72 to perform the corresponding movements. This pneumatic drive offers high efficiency and responsiveness, enabling rapid movement of cylinder 71 and accurate control of the piston rod's extension length and speed.

[0093] To ensure that the multi-stage piston rod 72 can rotate normally, a bearing is provided at the place where the piston rod is inserted into the cylinder 71. The outer ring 62 of the bearing is fixedly connected to the cylinder 71, and the multi-stage piston rod 72 is welded and fixed on the inner ring 63 of the bearing, so the multi-stage piston rod 72 can rotate normally.

[0094] In order to ensure the air tightness of the multi-stage piston rod 72, a bearing center ring 64 is rotatably installed on the bearing inner ring 63. The bearing center ring 64 is connected to the channel for transmitting gas, thereby maintaining air tightness.

[0095] Steel balls are provided between the bearing outer ring 62 , the bearing inner ring 63 and the bearing center ring 64 .

[0096] In order to further switch the driving force for rotating the rotating frame 21 to the power for rotating the mixing rod 23, the power connection mechanism 5 includes a first gear 51 welded to the rotating shaft 42, and the kit 43 is located below the first gear 51;

[0097] A second gear 52 is mounted on the outer surface of the multi-stage piston rod 72 at a height matching that of the first gear 51. A strong magnet 53 is embedded and fixed below the second gear 52. The multi-stage piston rod 72 is driven toward the rotating shaft 42 by the second driving mechanism 6, and the first gear 51 meshes with the second gear 52.

[0098] The strong magnet 53 approaches the sleeve 43, and the sleeve 43 moves upward by magnetic attraction, thereby controlling the first rib 44 to separate from the first protrusion 45. The sleeve 43 is made of a metal material that can be attracted by magnets.

[0099] The first gear 51 is welded to the rotating shaft 42 and meshes with the second gear 52, which is mounted on the outer surface of the multi-stage piston rod 72. The design of the first gear 51 and the second gear 52 forms a power transmission chain between the rotating shaft 42 and the piston rod. By driving the second gear 52, the rotational force is effectively transmitted to the multi-stage piston rod 72, which in turn drives the piston rod toward the rotating shaft 42.

[0100] The gear meshing ensures efficient and stable power transmission. The gear transmission structure has a high transmission ratio, which can generate a large driving force with a small force, thereby ensuring the precise movement of the multi-stage piston rod 72.

[0101] A strong magnet 53 is fixed below the second gear 52, near the sleeve 43. The function of the strong magnet 53 is to move the sleeve 43 upward through magnetic attraction, thereby controlling the separation of the first groove 44 from the first protrusion 45. Through magnetic attraction, the strong magnet 53 can accurately drive the sleeve 43, triggering the desired connection or separation action, ensuring that the system performs as intended.

[0102] Through non-contact driving, the strong magnet 53 provides a non-contact driving force, allowing the assembly 43 to move up or down smoothly, reducing mechanical friction and wear. This approach can extend the service life of mechanical components and improve reliability.

[0103] As long as the magnetic attraction force is sufficient, the adjustment is very precise to ensure that the kit 43 moves as required without excessive or insufficient movement, thereby achieving precise connection and disconnection control.

[0104] Compared with the traditional mechanical drive system, the use of the strong magnet 53 simplifies the power transmission path and avoids cumbersome mechanical contact components, thereby reducing space occupation and system complexity.

[0105] Furthermore, the magnetic attraction can provide a fast movement response, without the need for complex mechanical parts to achieve the movement of the kit 43. Through this design, tasks can be completed quickly, operation delays are reduced, and the work efficiency of the system is improved.

[0106] A pressurized air pipe 15 is also provided at the material delivery port, and a control air valve 16 is provided at the pressurized air pipe 15. The pressurized air pipe 15 is externally connected to a second external air pump 17. The control air valve 16 and the second external air pump 17 are electrically connected to the control module. The opening time of the second external air pump 17 is controlled by the control module, and the mixed material is pressurized and sprayed toward the inside of the barrel 1 through the pressurized air pipe 15.

[0107] The pressurized air pipe 15 and control valve 16 are primarily used to control the flow of gas. Gas is introduced into the barrel 1 through the pressurized air pipe 15, generating pressure to propel the material flow. The control valve 16 works in conjunction with the pressurized air pipe 15 to open and close the flow of gas as needed, precisely controlling the gas pressurization process. The injection pressure and flow rate of the material can be adjusted as needed to ensure efficient and stable production.

[0108] The second external air pump 17 is electrically connected to the control valve 16 via a control module, which precisely controls the start and stop times of the air pump. This allows the system to precisely adjust the air pump's operating state within a specific timeframe, ensuring a continuous and stable airflow through the pressurized air pipe 15. The control module can also adjust the air pump's duty cycle based on operational needs to accommodate varying production requirements.

[0109] The purpose of the pressurized air pipe 15 is to forcibly eject the material into the barrel 1 using pressurized gas. This ensures that the material is uniformly delivered to the desired location at a predetermined speed and pressure. The pressurized gas effectively prevents material from becoming clogged, accumulating, or unevenly distributed at the outlet 13, ensuring smooth material delivery.

[0110] The pressurized air pipe 15 can continuously maintain a certain air pressure to prevent the material from clogging the pipe due to accumulation or excessive viscosity, thereby ensuring the continuous operation of the production line.

[0111] The vibration assembly 10 includes a vibration motor 101 arranged above the rotating frame 21, a wireless power receiver 102 arranged above the vibration motor 101, and a wireless power output 103 embedded above the barrel 1. The wireless power output 103 is electrically connected to the control module 3. The control module 3 controls the cooperation between the wireless power output 103 and the wireless power receiver 102 to turn on the power of the vibration motor 101. The output section of the vibration motor 101 hits the inner wall of the rotating frame 21 to generate vibration, which cooperates with the mixing rod 23 to eliminate material bubbles.

[0112] The vibration motor 101 generates continuous vibrations on the inner wall of the rotating frame 21. This vibration is transmitted to the mixing rod 23, which is kneading the mixed material. This vibration causes the mixing rod 23 to vibrate slightly during the kneading process, effectively guiding the expulsion of bubbles, reducing and eliminating bubbles during the mixing process, thereby improving the uniformity and quality of the material. In particular, bubbles during the mixing process can cause uneven mixing and product quality issues.

[0113] By effectively eliminating bubbles in the material, the density and purity of the product are improved, ensuring the high quality of the final product.

[0114] To address the vibration motor power supply issue, the design of a wireless power receiver 102 and output device avoids the limitations and complexity of traditional wired connections. This wireless power supply method enables more flexible and convenient control of the vibration assembly 10 without affecting the movement of the rotating frame 21 and vibration motor 101.

[0115] The wireless power supply method makes the arrangement of the vibration component 10 more flexible, and there is no need to consider cable plugging or wiring issues, which facilitates the installation and adjustment of the equipment.

[0116] In order to maintain the fluidity of the material during the mixing and stirring process, a heating component 9 is set. Specifically, the heating component 9 includes an insulation layer 91 mounted on the outer side of the barrel 1, and an electric heating tube 92 arranged from bottom to top between the insulation layer 91 and the barrel 1. The electric heating tube 92 is electrically connected to the control module 3.

[0117] The electric heating tube 92 is a common electric heating device widely used in industrial applications requiring heating of materials or liquids. Its basic principle is to generate heat by passing an electric current through a resistance element within the electric heating tube 92. The specific operating principle is that electric current passes through the resistance element of the electric heating tube 92, which typically consists of a metal tube, an internal resistance wire (such as a nickel-chromium alloy wire), and an external protective layer (such as a metal casing). When the current passes through the resistance wire, the resistance converts electrical energy into heat energy.
