[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a feeding device for facilitating the coating of silicone rubber solution includes a support 1 and a feeding bucket 2. The feeding bucket 2 is mounted on the support 1. At least two feeding buckets 3 are mounted on the support 1 above the feeding bucket 2. Both the feeding bucket 2 and the feeding bucket 3 are equipped with a stirring assembly 4 and a heating assembly 5. The feeding bucket 3 is equipped with a discharge pipe 31 connected to the feeding bucket. The discharge pipe 31 is equipped with a first control valve 32. The bottom end of the feeding bucket 2 is equipped with the discharge pipe 21, and the discharge pipe 21 is equipped with a second control valve 22. The support 1 is equipped with a controller 6. The first control valve 32, the second control valve 22, the stirring assembly 4, and the heating assembly 5 are all connected to the controller 6.

[0023] The opening and closing of the feeding pipe is controlled by a second control valve, thereby achieving automatic feeding of the silicone rubber solution stored in the feeding tank. This greatly reduces labor intensity, improves production efficiency, and allows for precise control of the silicone rubber solution flow rate, reducing waste. Secondly, a feeding tank is installed on the support of the feeding tank. Since the feeding tank has a drop pipe connected to the feeding tank, it can continuously supply silicone rubber solution into the feeding tank, ensuring continuous feeding. Furthermore, each feeding tank is equipped with a stirring component and a heating component, which can effectively control the temperature and stirring speed within the feeding tank, ensuring thorough mixing of the raw materials and improving the quality of the silicone rubber solution. In addition, a stirring component and a heating component are installed inside the feeding hopper. When at least two silicone rubber solutions need to be mixed in the feeding hopper, the silicone rubber solutions can be stirred and mixed, further improving the quality of the silicone rubber solutions. Therefore, silicone rubber solutions with different compositions can be prepared according to different production needs to meet different production requirements. Finally, the controller is set up so that the first control valve, the second control valve, the stirring component, and the heating component are all connected to the controller, thus realizing automated operation. In addition, the feeding hopper is set on the support above the feeding hopper, which on the one hand ensures the feeding efficiency of the feeding pipe, and on the other hand makes the structure of the entire feeding device more compact, greatly reducing the space occupied by the entire feeding device.

[0024] The mixing assembly 4 includes a servo motor 41 and a mixing shaft 42. Both the feeding hopper 2 and the supply hopper 3 are equipped with flanges 7 for mounting the servo motor 41. The servo motor 41 includes a motor shaft 43. The mixing shaft 42 is mounted on the motor shaft 43 via a coupling 44. The mixing shaft 42 is equipped with mixing blades 45. The specific installation structure of the mixing blades is existing technology and will not be described in detail in this embodiment. By setting the mixing assembly to a servo motor and a mixing shaft, and since the mixing shaft is equipped with mixing blades, during operation, the servo motor only needs to drive the mixing shaft to rotate, which in turn drives the mixing blades to rotate, thus achieving the mixing of the raw materials and ensuring thorough mixing. The servo motor can precisely control the mixing speed of the mixing shaft to meet different mixing requirements. Secondly, the flange facilitates the installation and fixation of the servo motor, improving the stability of the entire mixing assembly installation. Finally, the coupling ensures that the power of the servo motor is smoothly transmitted to the mixing shaft, effectively reducing vibration and impact and improving the service life of the mixing assembly.

[0025] Both the feeding hopper 2 and the supply hopper 3 have mounting slots 8 at their bottom ends for installing heating components 5. The heating component 5 includes an electric heating element 51 and a power connection wire 52. One end of the power connection wire 52 is connected to the electric heating element 51; the specific connection structure is existing technology and will not be described in detail in this embodiment. The other end of the power connection wire 52 has a power plug 53. The mounting slots allow for precise positioning of the heating component, ensuring that the heating surface of the heating component is in contact with the bottom of the feeding hopper and the supply hopper, improving heat transfer efficiency, avoiding localized overheating or energy loss due to poor contact, and facilitating the installation and removal of the heating component. Using an electric heating element and a power connection wire for the heating component improves heating efficiency, and the overall structure is compact with high safety performance. The power plug on the power connection wire ensures correct connection to the mains power, achieving stable power supply to the electric heating element.

[0026] The feeding hopper 2 is provided with a downwardly inclined mounting sleeve 23, and the feeding pipe 21 is detachably mounted on the mounting sleeve 23. The mounting sleeve simplifies the installation structure between the feeding pipe and the feeding hopper, making it easier to clean the feeding pipe independently. In this embodiment, the feeding pipe and the mounting sleeve can be connected by threads, making overall installation and disassembly convenient and the connection reliable. Furthermore, the downwardly inclined structure of the mounting sleeve on the feeding hopper improves the feeding efficiency of the silicone rubber solution. In this embodiment, the downward inclination angle of the mounting sleeve is 15-45°, with 15°, 30°, and 45° being preferred. The number of mounting sleeves can be set differently according to actual production needs, such as two or three, to meet different feeding requirements.

[0027] The support 1 includes a base plate 11, a top plate 12, and a connecting column 13 disposed between the base plate 11 and the top plate 12. The discharge bucket 2 is disposed on the base plate 11, and the feed bucket 3 is disposed on the top plate 12. The top plate 12 is provided with a through hole 14 for the discharge pipe 31 to pass through. The support is configured as a connection between the base plate, the top plate, and the connecting column. Since the discharge bucket 2 is disposed on the base plate 11 and the feed bucket 3 is disposed on the top plate 12, the discharge bucket and the feed bucket can be installed independently on the support. In this embodiment, the feed buckets are evenly distributed on the top plate. Furthermore, the through hole facilitates the installation of the discharge pipe, prevents the discharge pipe from shaking when discharging material, and improves the discharge efficiency. The base plate 11 is provided with a first support frame 15 for mounting the feeding hopper 2, and the top plate 12 is provided with a second support frame 16 for mounting the supply hopper 3. Both the first support frame 15 and the second support frame 16 are provided with shock-absorbing pads 17. The first support frame effectively disperses the vibration load and silicone rubber solution impact force generated during the operation of the feeding hopper, and facilitates the disassembly and maintenance of the feeding hopper. Similarly, the second support frame effectively disperses the vibration load and silicone rubber solution impact force generated during the operation of the supply hopper, and facilitates the disassembly and maintenance of the supply hopper. Furthermore, the shock-absorbing pads effectively isolate the vibration generated by the feeding hopper and the supply hopper, reducing structural noise during operation and improving the overall service life. The bracket 1 is an integrated structure. This integrated structure simplifies the installation process between the various components of the bracket and improves the overall installation strength of the bracket.

[0028] The feeding hopper 3 is connected to a feeding pipe 33, and the feeding pipe 33 is equipped with a third control valve 34 connected to the controller 6. The feeding pipe allows for the feeding of raw materials without opening the feeding hopper, preventing dust or debris from entering the feeding hopper and improving feeding efficiency. Furthermore, the third control valve, connected to the controller, allows for precise control of the flow rate in the feeding pipe, enabling accurate feeding of raw materials. In this embodiment, the number of feeding pipes can be installed according to actual production needs. The specific installation structure is existing technology and will not be described in detail in this embodiment.

[0029] The feeding hopper 2 is equipped with a sensor 24 connected to the controller 6, which can monitor the position or state of the silicone rubber solution in the feeding hopper in real time to prevent overflow or dry running. Since the sensor is connected to the controller, automatic replenishment or automatic stopping of feeding can be achieved. In this embodiment, the sensor can be a pressure sensor, a liquid level sensor, a weighing sensor, or an infrared sensor. In this embodiment, a liquid level sensor is preferred. In actual use, the liquid level sensor transmits the liquid level information of the feeding hopper to the controller, and the controller controls the opening of the first control valve according to the received information, which can realize automated operation. The feeding hopper 3 is equipped with a nameplate 35. The nameplate can indicate the name, volume, date and other valid information of the silicone rubber solution in the feeding hopper, which helps the staff to quickly and accurately identify the silicone rubber solution. In this embodiment, the nameplate is made of stainless steel, which improves the service life of the nameplate.

[0030] In addition to the preferred embodiments described above, there are other embodiments of this utility model. Those skilled in the art can make various changes and modifications based on this utility model.
