Description

An edge sealing assembly for flat wire mesh Technical Field

[0001] This utility model relates to the field of wire mesh edge sealing technology, and in particular to an edge sealing component for flat wire mesh. Background Technology

[0002] Flat filament drying wire is a high-performance drying wire designed specifically for the drying section of high-speed paper machines. It is mainly used to transfer the paper web and optimize heat exchange efficiency during the paper drying process. Its core feature is that it uses flat filaments as warp and round filaments as weft, and achieves high strength, low air permeability and high stability through precision weaving technology. The main raw material is high hydrolysis resistant polyester monofilament, which has excellent high temperature resistance, hydrolysis resistance and corrosion resistance. It can adapt to the high temperature and high humidity environment of the drying section, and is especially suitable for production scenarios such as cultural paper, packaging paper and specialty paper.

[0003] In the prior art, when sealing the edges of flat wire mesh, heating mechanisms are mostly used to directly heat the edges of the flat wire mesh to melt them. However, this can easily cause the material to stick to the sealing mechanism, affecting subsequent operations of the device. Furthermore, manual adjustments are required to accommodate flat wire mesh of different sizes, which is not conducive to improving the sealing efficiency of the device. Therefore, in order to solve the above problems, this utility model proposes a sealing component for flat wire mesh. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides an edge sealing component for flat wire mesh. The position of slider one is adjusted by a servo motor, eliminating the need for manual adjustment and improving the working efficiency of the device. Ultrasonic welding pads are used to generate heat through intense friction between material molecules, causing the edges of the flat wire mesh to fuse and seal. High-frequency vibration prevents material from adhering to the edge sealing mechanism and removes excess material without the need for secondary processing.

[0005] This utility model provides the following technical solution: an edge sealing assembly for flat wire mesh, including a fixed frame. Two hydraulic rods are fixedly installed at the top of the inner cavity of the fixed frame and are symmetrically distributed front to back. A lifting groove is fixedly installed at the telescopic end of each hydraulic rod. A servo motor is fixedly installed at the rear of the lifting groove. A threaded rod is fixedly connected to the output shaft of the servo motor via a coupling. The threaded rod has symmetrical threads on both sides and is movably sleeved in the inner cavity of the lifting groove. Two sliders are movably sleeved on the threaded rod and are symmetrically distributed front to back. A drive motor is fixedly installed on opposite sides of each slider. The output shaft of the drive motor is movably sleeved in the inner cavity of the slider. An ultrasonic welding pad is fixedly connected to the output shaft of the drive motor via a coupling. The position of the slider is adjusted by the servo motor, eliminating the need for manual adjustment and improving the working efficiency of the device. The ultrasonic welding pad generates heat through intense friction between material molecules, causing the edge of the flat wire mesh to fuse and seal, preventing material from adhering to the edge sealing mechanism. High-frequency vibration simultaneously removes excess material, eliminating the need for secondary processing.

[0006] Preferably, a support plate is provided below the fixing frame, and six support rods are evenly fixedly installed on the bottom of the support plate. Two fixing plates are fixedly installed on the upper part of the support plate and are symmetrically distributed front and back. The upper part of the fixing plates is fixedly connected to the fixing frame. A pad is fixedly installed on the upper part of the support plate and between the two fixing plates. The pad is located directly below the ultrasonic welding pad. When the flat wire mesh moves to the pad, the ultrasonic welding pad is driven to descend for edge sealing by the moving mechanism. The pad can provide support for the edge sealing operation.

[0007] Preferably, a feeding roller and a receiving roller are arranged between the two fixed plates. The feeding roller and the receiving roller are located on the left and right sides of the pad, respectively. Electric actuators are symmetrically fixed on the corresponding surfaces of the two fixed plates. There are four electric actuators in pairs. A connecting block is fixedly installed on the telescopic end of the electric actuator. The flat wire mesh is wound around the feeding roller, and one end of the flat wire mesh is fixed to the receiving roller, so that the feeding roller and the receiving roller can drive the flat wire mesh to move in the horizontal direction, which is beneficial for continuous edge sealing of the flat wire mesh.

[0008] Preferably, a material transfer roller 1 is movably connected to the side of the connecting block away from the electric push rod via a shaft. A spring is fixedly installed at the top of the inner cavity of the connecting block, and a slider 2 is fixedly installed at the bottom of the spring. A material transfer roller 2 is movably connected to the side of the slider 2 away from the electric push rod via a shaft. The material transfer roller 2 is located above the material transfer roller 1, placing the side of the flat wire mesh between the material transfer roller 1 and the material transfer roller 2 to assist in the movement of the flat wire mesh, prevent the flat wire mesh from shifting during the edge sealing process, and ensure the yield rate of the flat wire mesh after edge sealing.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] 1. Adjusting the position of the two sliders by servo motors facilitates the sealing of flat wire mesh of different widths without the need for manual adjustment, thus improving the working efficiency of the device. By setting ultrasonic welding pads, the inverse piezoelectric effect is used to convert electrical energy into mechanical vibration energy, which drives the material molecules to generate heat through intense friction, causing the edges of the flat wire mesh to fuse and seal. Compared with direct heating, high-frequency vibration can prevent the flat wire mesh material from sticking to the sealing mechanism, and the sealing process is fast and has no exhaust emissions. Vibration removes excess material while sewing the edges of the flat wire mesh, forming a smooth edge without burrs, without the need for secondary processing.

[0011] 2. The connecting block is moved by the electric push rod, so that the side of the flat wire mesh is located between the first and second conveyor rollers. When the thickness of the flat wire mesh is large, the second conveyor roller can be lifted upward, which drives the second slider to move upward. The spring is compressed and generates elastic potential energy, which makes the second conveyor roller generate a certain downward pressure to assist the movement of the flat wire mesh. This allows the device to adapt to different specifications of flat wire mesh, effectively improving the applicability of the device, preventing the flat wire mesh from shifting during the edge sealing process, and ensuring the yield rate of the flat wire mesh after edge sealing.

An ultrasonic welding pad 8 is fixedly connected to the output shaft of the drive motor 7 via a coupling. The servo motor 4 drives... Rotating the threaded rod 5 adjusts the positions of the two sliders 6, which facilitates the sealing of flat wire mesh of different widths without the need for manual adjustment, thus improving the working efficiency of the device. At the same time, the drive motor 7 and the ultrasonic welding pad 8 are started, causing the drive motor 7 to drive the ultrasonic welding pad 8 to rotate. The hydraulic rod 2 drives the lifting groove 3 to descend, bringing the ultrasonic welding pad 8 close to the surface of the flat wire mesh. The ultrasonic welding pad 8 converts electrical energy into mechanical vibration energy through the inverse piezoelectric effect, causing intense friction between material molecules and instantaneous heat generation, which fuses and seals the edge of the flat wire mesh. Compared with directly heating the roller, high-frequency vibration can prevent the flat wire mesh material from sticking to the sealing mechanism. Moreover, the sealing process is fast and there is no exhaust gas emission. The vibration removes excess material while sewing the edge of the flat wire mesh, forming a smooth edge without burrs, without the need for secondary processing.

[0019] A support plate 9 is provided below the fixed frame 1. Six support rods 10 are evenly fixedly installed at the bottom of the support plate 9. Two fixed plates 11 are fixedly installed on the upper part of the support plate 9, symmetrically distributed front and back. The upper part of the fixed plates 11 is fixedly connected to the fixed frame 1. A pad 12 is fixedly installed on the upper part of the support plate 9 and between the two fixed plates 11. The pad 12 is located directly below the ultrasonic welding pad 8. A feeding roller 13 and a receiving roller 14 are arranged between the two fixed plates 11. The feeding roller 13 and the receiving roller 14 are located to the left and right of the pad 12, respectively. Four electric push rods 15 are symmetrically fixedly installed on the corresponding surfaces of the two fixed plates 11, arranged in pairs.

The electric push rod 15 is activated to drive the connecting block 16 to move, so that the side of the flat wire mesh is located between the transfer roller 1 17 and the transfer roller 20. When the thickness of the flat wire mesh is large, the transfer roller 20 can be lifted upward, driving slider 2 19 to move upward. The spring 18 is compressed and generates elastic potential energy, so that the transfer roller 20 generates a certain downward pressure, which better assists the movement of the flat wire mesh. This allows the device to adapt to flat wire mesh of different specifications, effectively improving the applicability of the device, avoiding the flat wire mesh from shifting during the edge sealing process, and ensuring the yield rate of the flat wire mesh after edge sealing.

The electric actuator 15 is activated to drive the connecting block 16 to move, so that the side of the flat wire mesh is located between the first transfer roller 17 and the second transfer roller 20. When the thickness of the flat wire mesh is large, the second transfer roller 20 can be lifted upward, driving the second slider 19 to move upward. The spring 18 is compressed to generate elastic potential energy, so that the second transfer roller 20 generates a certain downward pressure. To better assist the movement of the flat wire mesh, when the flat wire mesh moves onto the pad 12, the servo motor 4 drives the threaded rod 5 to rotate, adjusting the position of the two sliders 6. At the same time, the drive motor 7 and the ultrasonic welding pad 8 are started, causing the drive motor 7 to drive the ultrasonic welding pad 8 to rotate. The hydraulic rod 2 drives the lifting groove 3 to descend, bringing the ultrasonic welding pad 8 close to the surface of the flat wire mesh. The ultrasonic welding pad 8 converts electrical energy into mechanical vibration energy through the inverse piezoelectric effect, causing intense friction between material molecules and instantaneous heat generation, which causes the edge of the flat wire mesh to fuse and seal.
