[0018] Example 1: Reference Figure 1-4The ceramic fiber blanket production line feeding and spreading device shown includes a transport frame 1, which supports the overall structure of the device, carries the installation of various components, and provides a transport channel for ceramic fiber raw materials, ensuring stable transmission of the raw materials within the production line. An electrostatic guiding component is installed inside the transport frame 1 to eliminate static electricity generated during raw material transmission, preventing static electricity from causing raw material adsorption and agglomeration, and ensuring uniform spreading. The electrostatic guiding component includes a stainless steel beam 17 fixedly connected to the inner wall of the transport frame 1, serving as the basic carrier for electrostatic conduction, supporting conductive silicone strips and transmitting static electricity. A conductive silicone strip 18 is installed on the outer side of the stainless steel beam 17, directly contacting the raw material and adhering to the raw material surface for efficient static electricity conduction, while also possessing a certain degree of elasticity to avoid damaging the raw material. Multiple metal contact pieces 20 are embedded on the inner side of the conductive silicone strip 18 to enhance the conductivity between the conductive silicone strip and the stainless steel beam, ensuring a smooth electrostatic conduction path. The metal contact pieces 20 are in contact with the stainless steel beam 17. Both ends of the stainless steel beam 17 are fixedly connected to grounding frames 13 to conduct the static electricity conducted by the stainless steel beam to the ground, achieving static elimination. The grounding frame 13 passes through the transport frame 1, and a pair of bolts 14 are provided on the outer side of the grounding frame 13 to fix the relative position of the grounding frame and the transport frame, preventing the grounding frame from loosening and affecting the static elimination effect. The outer side of the grounding frame 13 has threaded holes that match the bolts 14, providing an installation mating structure for the bolts and ensuring stable locking. A positioning frame 6 is fixedly connected to the outer side of the transport frame 1 to provide localized moisture... The system provides installation support for components such as fans, determining the position of each component within the device. A localized humidification component is installed on the outer side of the positioning frame 6 to locally humidify the raw materials, regulating their moisture content and preventing dust generation or adverse effects on subsequent processing performance due to excessive dryness. The localized humidification component includes a high-pressure micro-mist humidifier 7 fixedly connected to the outer side of the positioning frame 6, generating high-pressure micro-mist to provide a water source for humidifying the raw materials. The mist droplets are fine and uniform, preventing over-wetting. A water distribution pipe 8 is fixedly connected to the inner wall of the positioning frame 6, delivering the water mist generated by the high-pressure micro-mist humidifier to each atomizing nozzle for uniform water mist distribution. The output end of the high-pressure micro-mist humidifier 7 passes through the positioning frame 6 and is connected to the water distribution pipe 8. The outer side of the water distribution pipe 8 is fixedly connected to... Multiple interconnected atomizing nozzles 9 are connected to the positioning frame 6, which atomize and spray the water mist delivered by the water distribution pipe, directly acting on the surface of the raw material to achieve localized and uniform humidification of the raw material. A fan 10 is fixedly connected to the outside of the positioning frame 6 to generate airflow, which is used to regulate the surface humidity of the raw material, accelerate the diffusion of excess water mist, and prevent water mist from accumulating in the device. The output end of the fan 10 passes through the positioning frame 6, and an air distribution pipe 11 is fixedly connected to the inner wall of the positioning frame 6 to deliver the airflow generated by the fan to each nozzle, so as to achieve uniform airflow distribution. Multiple interconnected nozzles 12 are fixedly connected to the outside of the air distribution pipe 11 to direct the airflow delivered by the air distribution pipe towards the raw material, assist in regulating the humidity of the raw material, and can also disperse a small number of agglomerated particles on the surface of the raw material. The output end of the fan 10 is connected to the air distribution pipe 11.A moisture sensor 19 is installed on the inner wall of the positioning frame 6 to detect the humidity around the raw materials in the device in real time. This provides data for adjusting the operation of the local humidification components, ensuring that the humidity is maintained within a reasonable range. A fixing frame 2 is fixedly connected to the outer side of the transport frame 1 to provide installation support for the electric ion air knife and fix its position. An electric ion air knife 3 is installed on the inner wall of the fixing frame 2 to generate ion air, further eliminating residual static electricity on the surface of the raw materials. It can also assist in cleaning fine dust on the surface of the raw materials, improving the cleanliness of the raw materials.

[0019] Example 2: Reference Figure 1-4 Based on the same concept as in Embodiment 1 above, this embodiment also proposes that an air guide hood 4 is provided on the inner wall side of the fixing frame 2. The air guide hood 4 can concentrate and guide the airflow output by the electric ion air knife 3 to avoid airflow diffusion and ensure that the airflow accurately acts on the target area. The output end of the electric ion air knife 3 faces the air guide hood 4, and multiple Venturi tubes 5 are provided on the outer side of the air guide hood 4. The Venturi tubes 5 can utilize the Venturi effect to increase the local airflow speed and reduce the air pressure when the airflow passes through, thereby enhancing the adsorption or purging effect of the airflow and further optimizing the airflow efficiency. A pair of guide rods 16 are provided on the inner side of the transport frame 1. The guide rods 16 can limit and guide the materials during the transport process, prevent the materials from deviating, and ensure the stability of the transport path. A pair of motors 15 are fixedly connected to the outer side of the transport frame 1. The motors 15 provide the power source for the operation of the guide rods 16. The output end of the motor 15 passes through the transport frame 1 and is fixedly connected to the guide rods 16, so that the power of the motor 15 can be directly transmitted to the guide rods 16, driving the guide rods 16 to operate along the set trajectory, so as to achieve stable transport of materials.

[0020] The working principle of this utility model is as follows: The control motor 15 drives the guide rod 16 to rotate, conveying the blanket. The blanket bypasses the conductive silicone strip 18, and utilizing the elasticity of the silicone, it actively adheres to the bottom of the blanket during stacking, eliminating gaps. Simultaneously, the conductive silicone can directly contact the blanket fibers, and the multiple metal contact pieces 20 strengthen the conductive connection between the silicone strip and the stainless steel frame, preventing "conductive breakpoints" caused by the degradation of conductivity after long-term use. The grounding frame 13 guides static electricity, and bolts passing through the grounding frame 13 are crimped and fixed to the grounding wire of the workshop grounding grid. The high-pressure micro-mist humidifier 7 is controlled to... The arrangement of water distribution pipe 8 and multiple atomizing nozzles 9 sprays water mist onto the surface of the blanket and the surrounding environment through an array of nozzles, forming a "localized humidifying air curtain" to reduce air insulation and accelerate the natural dissipation of static electricity. The arrangement of fan 10, air distribution pipe 11, and air jet 12 ensures that the humidity of the processing area meets the requirements for static electricity elimination while preventing the blanket from absorbing moisture and becoming brittle due to excessive contact with water mist. The electric ion air knife 3 generates an ionization field, ionizing compressed air into positive and negative ions, which are then sprayed at high speed onto the surface of the blanket to neutralize static electricity. The arrangement of air guide hood 4 and multiple venturi tubes 5 accelerates the positive and negative ions.
