[0002] In the production of electrical equipment, the mixing process of insulating materials is a key process, which usually requires different types of raw materials to be mixed evenly in a specific ratio to ensure the stable performance of the final insulating material.

DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0030] In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0031] Reference Figure 1-8 As shown, a mixing device for preparing insulating materials for electrical equipment comprises: a barrel 1, a stirring and kneading component 2 arranged inside the barrel 1, and a driving component for driving the stirring and kneading component 2 to work; The stirring and kneading assembly 2 comprises 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. The driving assembly includes a first driving mechanism 4 for driving the rotating frame to rotate, a power connection mechanism 5 for driving the two mixing rods 23 to rotate, a second driving mechanism 6 for controlling the power connection mechanism 5 to move left / right, and a docking mechanism 7 for controlling the power connection mechanism 5 to dock / separate with the mixing rod 23; A control module 3 and a visual positioning module 8, wherein 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; The material feeding port inputs a variety of materials toward 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; Through the control module 3 and the visual positioning module 8, the second driving mechanism 6 is controlled to laterally drive the power connection mechanism 5 to move leftward / rightward to just above the mixing rod 23, and cooperates with the driving of the docking mechanism 7 to connect the mixing rod 23 with the power connection mechanism 5, and the power connection mechanism 5 is driven by the second driving component to connect with the first driving mechanism 4, and the two mixing rods 23 are controlled to engage and rotate through the connection power.

[0032] 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, and 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 positions 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 toward the middle. This allows the material to be fully kneaded and stirred, avoiding the generation of dead corners.

[0033] The material can be stirred more evenly during the mixing process. Through the combination of the strip-shaped through hole 22 and the sliding mixing rod 23, the stirring range and strength can be adjusted according to the actual needs of the material, thereby ensuring the high efficiency of the mixing process and the consistency of the material, and avoiding the uneven stirring of the material in the traditional stirring system.

[0034] The engagement of the power connection mechanism 5 with the mixing rod 23 is controlled by the second driving mechanism 6. This design enables the stirring device to adjust the rotation mode and rotation speed of the mixing rod 23 as needed. The power connection mechanism 5 can not only transmit the driving force to the mixing rod 23, but also ensure the accuracy of the rotation and engagement of the mixing rod 23. Through the docking mechanism 7, the power connection mechanism 5 can accurately dock and separate with the mixing rod 23.

[0035] The position of the mixing rod 23 can be monitored in real time by the visual positioning module 8, and feedback information can be provided to the control module 3, so that the control system can accurately control the mixing process. The existence of the visual positioning module 8 enables the system to automatically calibrate and adjust the equipment action according to the actual situation to ensure that the docking mechanism 7 and the mixing rod 23 can be docked correctly.

[0036] Through the visual positioning module 8, the system can dynamically adjust according to the real-time operating status, improving the accuracy and automation of the equipment. The control module 3 can optimize the movement trajectory of the mixing rod 23 based on the feedback information of the visual positioning module 8 to ensure that each mixing can achieve the expected effect.

[0037] The first driving mechanism 4 and the second driving mechanism 6 are used in coordination to respectively rotate the rotating frame 21 and move the power connection mechanism 5 left and right. This division of labor can make the stirring process more precise, and the synergy of rotation and movement ensures stirring uniformity and flexibility.

[0038] By working together with two independent drive mechanisms, the system can control the mixing process more precisely. For example, the first drive mechanism 4 can independently control the rotation rate of the rotating frame 21, while the second drive mechanism 6 can adjust the position of the mixing rod 23 as needed. This refined control ensures uniform mixing of the materials and improves work efficiency while avoiding over-mixing or under-mixing.

[0039] Through this refined and modular design, the equipment can not only handle a variety of materials, but also significantly improve the mixing effect. The precise control of each component makes the material mixing more uniform, and can quickly and effectively eliminate bubbles, improving the quality of the final product. At the same time, the system's automation level is improved, reducing the complexity and errors of manual operation, ensuring the efficiency and reliability of equipment operation.

[0040] In order 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 a plurality of 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 meshed with each other. The inner wall of the strip-shaped through hole 22 is provided with a side groove 24 , and a ring piece 233 is welded above the main rod 231 . The ring piece 233 is inserted into the side groove 24 . The mixing rod 23 is installed on the rotating frame 21 through the cooperation between the ring piece 233 and the side groove 24 .

[0041] When in use, the ring piece 233 supports the mixing rod 23 , and 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 .

[0042] The first driving mechanism 4 comprises a first motor 41 installed above the barrel 1, a rotating shaft 42 is inserted into the output end below the first motor 41, a sleeve 43 is slidably arranged below the rotating shaft 42, and a first ridge groove 44 is arranged below the sleeve 43; A first protrusion 45 corresponding to the first rib groove 44 is disposed 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.

[0043] In use, the first driving mechanism 4 drives the rotation of the rotating frame 21 through the first motor 41, and the motor transmits power to the rotating frame 21 through 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 helps to ensure the smooth transmission of power and rotation stability. The matching structure of the first rib groove 44 and the first protrusion 45 actually guides the movement direction of the rotating frame 21 stably and accurately through mechanical docking. The downward action of the self-weight of the sleeve 43 enables the rib groove to automatically dock with the protrusion, and no manual operation is required to ensure the accurate docking of the parts.

[0044] The matching design of the first rib groove 44 and the first protrusion 45 enables the kit 43 to maintain a firm connection with the rotating frame 21. The combination of the rib groove and the protrusion structure guides and completes the automatic docking through the self-weight, avoids the complexity of external operation, and can quickly and stably complete the connection and disconnection. The precise matching of the rib groove and the protrusion avoids the situation that the rotating frame 21 is offset or unstable during operation. The relative positioning of the rib groove and the protrusion ensures that there will be no motion errors due to looseness or misalignment during the rotation of the rotating frame 21, thereby achieving precise motion control.

[0045] The weight of the set 43 descends to ensure that the set 43 and the first rib groove 44 can be smoothly and automatically docked. 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.

[0046] 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.

[0047] When in use, the second driving mechanism 6 can achieve lateral movement of the docking mechanism 7 through the telescopic guide rod motor 61 arranged above the barrel 1. The output end of the telescopic guide rod motor 61 is connected to the docking mechanism 7, and its lateral movement is controlled by the control module 3. The setting of the telescopic guide rod motor 61 is intended to provide an efficient and accurate power source to drive the docking mechanism 7 to perform lateral displacement. The introduction of the control module 3 is to achieve precise control of the motor movement.

[0048] 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.

[0049] The telescopic guide rod motor 61 can provide a strong lateral driving force to ensure that the docking mechanism 7 can complete the position adjustment in a short time, thereby improving work efficiency. The control module 3 can precisely control the motor to ensure that the lateral movement of the docking mechanism 7 can be accurately executed to avoid errors and unnecessary deviations.

[0050] The output end of the telescopic guide rod motor 61 is arranged in opposite directions, so that the motor can better drive the lateral movement of the docking mechanism 7.

[0051] By setting the coordinated work of the telescopic guide rod motor 61 and the control module 3, the second driving mechanism 6 can realize the precise lateral movement of the docking mechanism 7. After the telescopic guide rod motor 61 is fully extended, it just cooperates with the power connection mechanism 5, which not only improves the flexibility and operation efficiency of the equipment, but also reduces human errors through automatic control, and enhances the stability and reliability of the entire system.

[0052] The docking mechanism 7 includes a cylinder 71 welded and fixed to the output end of the telescopic guide rod motor 61, a multi-stage piston rod 72 is rotatably mounted at the output end of the lower end of the cylinder 71, the cylinder 71 is externally connected to a first external air pump, the first external air pump is electrically connected to the control module 3, and a second convex block 721 is provided at the end of the multi-stage piston rod 72; A second ridge groove 234 matching 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.

[0053] When in use, the docking mechanism 7 realizes precise driving of the multi-stage piston rod 72 through the cylinder 71 and the multi-stage piston rod 72, and the first external air pump connected to the cylinder 71 provides air pressure support. The end of the multi-stage piston rod 72 is provided with a second protrusion 721, which cooperates with the second ridge groove 234 on the mixing rod 23 for precise connection. The control module 3 controls the start of the external air pump, and then adjusts the action of the cylinder 71 and the extension length of the piston rod to ensure the connection is fixed. This design can complete a fast and stable connection operation through the action of air pressure, meeting the requirements for accuracy and force under different working conditions.

[0054] By adopting the air cylinder 71 and the multi-stage piston rod 72, the complicated gears and transmission devices that may be involved in the traditional mechanical connection method are reduced, and the complexity of the mechanical structure is reduced. The combination of the air cylinder 71 and the external air pump can provide a large driving force, ensuring that the multi-stage piston rod 72 can be extended quickly and effectively, ensuring that the connection process is completed efficiently.

[0055] The second protrusion 721 provided at the end of the multi-stage piston rod 72 is inserted into the second rib groove 234 to achieve connection with the mixing rod 23. The core of this design is to make the connection process more stable and accurate through the cooperation between the protrusion and the rib groove. In this way, it can be ensured that under the drive of the cylinder 71, the movement of the piston rod can quickly and reliably connect and fix the multi-stage piston rod 72 and the mixing rod 23.

[0056] The external air pump controls the start and stop of the air cylinder 71 through the control module 3. The air pump provides air pressure support to push the piston rod in the air cylinder 71 to extend or retract, thereby driving the multi-stage piston rod 72 to perform corresponding actions. The air pressure drive method has high efficiency and response speed, can quickly complete the action of the air cylinder 71, and accurately control the extension length and speed of the piston rod.

[0057] 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 bearing outer ring 62 is fixedly connected to the cylinder 71, and the multi-stage piston rod 72 is welded and fixed on the bearing inner ring 63, so the multi-stage piston rod 72 can rotate normally.

[0058] 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, and the bearing center ring 64 is connected to the channel for transmitting gas, thereby maintaining air tightness.

[0059] Steel balls are arranged between the bearing outer ring 62 , the bearing inner ring 63 and the bearing center ring 64 .

[0060] The power connection mechanism 5 includes a first gear 51 welded and fixed on the rotating shaft 42, and the kit 43 is located below the first gear 51; A second gear 52 matching the height of the first gear 51 is installed on the outer ring surface of the multi-stage piston rod 72, and a strong magnet 53 is embedded and fixed under the second gear 52. The multi-stage piston rod 72 is driven by the second driving mechanism 6 to move toward the rotating shaft 42, and the first gear 51 is meshed with the second gear 52; The strong magnet 53 approaches the sleeve 43, and the sleeve 43 moves upward, controlling the first rib 44 to disengage from the first protrusion 45. The first gear 51 is welded and fixed on the rotating shaft 42, meshing with the second gear 52, and the second gear 52 is installed on the outer ring 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 can be effectively transmitted to the multi-stage piston rod 72, thereby driving the piston rod to move toward the rotating shaft 42.

[0061] The gear meshing can ensure efficient and stable power transmission. The gear transmission structure has a high transmission ratio and can generate a large driving force through a small force, thereby ensuring the precise movement of the multi-stage piston rod 72.

[0062] A strong magnet 53 is fixed below the second gear 52, close to the sleeve 43. The function of the strong magnet 53 is to move the sleeve 43 upward by magnetic attraction, thereby controlling the separation of the first rib groove 44 from the first protrusion 45. Through the magnetic attraction, the strong magnet 53 can accurately drive the sleeve 43, triggering the required connection or separation action, and ensuring that the system performs the predetermined operation.

[0063] Through non-contact driving, the strong magnet 53 provides a non-contact driving force, so that the kit 43 can move up or down smoothly, reducing mechanical friction and wear. This approach can extend the service life of mechanical components and improve reliability.

[0064] As long as the magnetic attraction 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.

[0065] Compared with the traditional mechanical drive system, the use of strong magnets 53 simplifies the power transmission path and avoids cumbersome mechanical contact parts, thereby reducing space occupation and system complexity.

[0066] And the magnetic attraction can provide a fast movement response, without complex mechanical parts to achieve the movement of the kit 43. Through this design, the task can be completed quickly, the delay of the operation is reduced, and the working efficiency of the system is improved.

[0067] The upper side of the barrel 1 is provided with a plurality of feeding ports, and the lower side of the barrel 1 is provided with an output port; A feed switch 12 is disposed at each of the feed ports 11 , and a discharge switch 14 is disposed at the discharge port. Both the feed switch 12 and the discharge switch 14 are electrically connected to the control module 3 .

[0068] 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 a 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.

[0069] The pressurized air pipe 15 and the control air valve 16 are mainly used to control the inflow of gas. The gas is introduced into the barrel 1 through the pressurized air pipe 15, thereby generating pressure to promote the flow of materials. The control air valve 16 cooperates with the pressurized air pipe 15 to open or close the gas inflow when needed, and accurately control the gas pressurization process. The injection pressure and flow rate of the material can be adjusted as needed to ensure high efficiency and stability in the production process.

[0070] The second external air pump 17 is electrically connected to the control air valve 16 through the control module, and the control module can accurately control the start and stop time of the air pump. This enables the system to accurately adjust the working state of the air pump within a specific time to ensure that the pressurized air pipe 15 provides a continuous and stable airflow. The control module can also adjust the working cycle of the air pump according to the operation requirements to adapt to different production requirements.

[0071] The purpose of the pressurized air pipe 15 is to force the material to be ejected into the barrel 1 by pressurized gas, thereby ensuring that the material can be uniformly transported to the designated location at a certain speed and pressure. The pressurized gas can effectively prevent the material from being blocked, accumulated or unevenly distributed at the outlet 13, thereby ensuring the smooth delivery of the material.

[0072] 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.

[0073] In order to maintain the fluidity of the material during the mixing and stirring process, a heating component 9 is provided. Specifically, the heating component 9 includes an insulating layer 91 sleeved on the outer side of the barrel 1, and an electric heating tube 92 arranged from bottom to top between the insulating layer 91 and the barrel 1, and the electric heating tube 92 is electrically connected to the control module 3.

[0074] The electric heating tube 92 is a common electric heating device, which is widely used in industrial fields that need to heat materials or liquids. Its basic principle is to pass current through the resistance element inside the electric heating tube 92 to generate heat, thereby achieving the purpose of heating. Specific working principle The current passes through the resistance element of the electric heating tube 92. The electric heating tube 92 is usually composed of a metal tube, an internal resistance wire (such as a nickel-chromium alloy wire) and an external protective layer (such as a metal shell). When the current passes through the resistance wire, due to the existence of resistance, the electrical energy will be converted into heat energy.
