Description

A clog-resistant and wear-resistant papermaking wire assembly Technical Field

[0001] This utility model relates to the field of papermaking equipment technology, and in particular to a clog-resistant and wear-resistant papermaking wire assembly. Background Technology

[0002] In the papermaking process, the paper wire, as a crucial component supporting the pulp and assisting in dewatering, directly impacts papermaking efficiency and quality. Existing paper wire assemblies suffer from several problems in practical applications. On one hand, during pulp dewatering, the wire is prone to detachment or breakage due to vibration, friction, and other factors, leading to production interruptions and affecting the paper machine's efficiency. On the other hand, pulp particles easily adhere to the wires, and fine fibers can clog the mesh, hindering dewatering, reducing dewatering efficiency, increasing energy consumption, and ultimately affecting paper quality. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this utility model provides a clog-resistant and wear-resistant papermaking wire assembly, which has the advantages of fixing the papermaking wire and preventing it from falling off and breaking, as well as preventing the papermaking wire from clogging and improving dewatering efficiency, thus solving some of the problems mentioned in the background technology.

[0004] This utility model provides the following technical solution: a clog-resistant and wear-resistant papermaking wire assembly, comprising a papermaking wire roll, a frame, and an ultrasonic generator. The frame has symmetrically arranged cavities at its left and right ends. A groove is provided near the center of the lower end of each cavity. A lower rubber pad is fixedly installed inside the groove. Uniformly distributed anti-detachment teeth are provided on the upper end of the lower rubber pad. An electric push rod is fixedly installed at both ends of the frame. The lower output end of each electric push rod passes through a cavity and is fixedly installed with a metal groove. An upper rubber pad is fixedly installed inside the metal groove. A pressure rod is fixedly connected to the far ends of the metal grooves. The lower end of the pressure rod is higher than the lower end of the upper rubber pad. A roll frame passes through the inside of the papermaking wire roll. A movable base is fixedly installed between the lower ends of the roll frame.

[0005] Furthermore, the upper end face of the lower rubber pad is flush with the lower end of the cavity, and the upper and lower rubber pads are adapted to each other to ensure the rationality of the structural design.

[0006] Furthermore, the open end of the papermaking wire roll passes through the frame, and both the left and right ends of the papermaking wire roll are laid flat inside the cavity and close to the inner side wall, which ensures that the pressure rod can also press and fix the papermaking wire, thus improving the fixing effect.

[0007] Furthermore, L-shaped positioning plates are fixedly installed on both the left and right sides of the lower end of the frame. The lower end of each L-shaped positioning plate is through which evenly distributed electric push rods are fixedly installed. An adjustment frame is fixedly installed between the upper ends of the electric push rods. This integrated structural design reduces space occupation.

[0008] Furthermore, composite spring assemblies are fixedly installed at the four corners of the upper end of the adjustment frame, and a vibration frame is fixedly installed between the upper ends of the composite spring assemblies. The composite spring assemblies combine the nonlinearity of rubber springs and the large deformation characteristics of metal helical springs, providing support while improving vibration transmission efficiency.

[0009] Furthermore, a uniformly distributed spherical hinge is fixedly installed at the middle position of the upper end of the adjustment frame. An amplitude transformer is fixedly connected to the ball of the spherical hinge. The upper end of the amplitude transformer is fixedly connected to the vibration frame. The amplitude transformer is electrically connected to the ultrasonic generator, which ensures the vibration uniformity of the vibration frame.

[0010] The advantages of this utility model are as follows:

[0011] 1. The electric push rod lowers the metal trough, causing the upper rubber pad to press down and engage with the lower rubber pad to press firmly against the papermaking wire. Simultaneously, the pressure rod further secures the edge of the papermaking wire. The anti-slip teeth on the upper and lower rubber pads are misaligned and embedded into the mesh of the papermaking wire, greatly enhancing the anti-slip effect and effectively preventing the papermaking wire from falling off during pulp dewatering. Furthermore, the elastic properties of the rubber material prevent it from breaking due to friction and vibration during the fixing process. When the papermaking wire needs to be replaced, simply operate the electric push rod to release the fixation, pull out the worn part, and re-fix it. The operation is simple and quick, allowing for rapid replacement, especially in unexpected situations, greatly reducing replacement time and effectively ensuring the production efficiency of the papermaking machine.

[0012] 2. Using the electric push rod two to raise the adjusting frame, the vibrating frame is brought into contact with the lower end of the papermaking wire. After turning on the ultrasonic generator, the vibration frame generates high-frequency mechanical vibration through the amplification effect of the amplitude transformer and the flexibility of the spherical hinge, which acts on the papermaking wire, producing a micron-level amplitude. This vibration can break the adhesion between the pulp particles and the wires, suspending the fine fibers, reducing the contact area with the mesh, and effectively preventing clogging. At the same time, the vibration energy can also promote the directional alignment of the fibers, forming a uniform void structure, which significantly improves the dewatering efficiency.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please refer to Figures 1-3. A clog-resistant and wear-resistant papermaking wire assembly includes a papermaking wire roll 1, a frame 2, and an ultrasonic generator. The frame 2 has symmetrically arranged cavities 3 at its left and right ends. A groove 4 is provided near the center of the lower end of each cavity 3. A lower rubber pad 5 is fixedly installed inside the groove 4. Evenly distributed anti-detachment teeth 6 are provided on the upper end of the lower rubber pad 5. Electric push rods 7 are fixedly installed at both ends of the frame 2. The lower output end of each electric push rod 7 penetrates into the cavity 3 and is fixedly installed with a metal groove 8. An upper rubber pad is fixedly installed inside the metal groove 8. 9. A pressure bar 10 is fixedly connected to the far ends of the metal grooves 8. The lower end of the pressure bar 10 is higher than the lower end of the upper rubber pad 9. A roll frame 18 runs through the inside of the papermaking wire roll 1. A movable base 19 is fixedly installed between the lower ends of the roll frame 18. The upper surface of the lower rubber pad 5 is flush with the lower end of the cavity 3. The upper rubber pad 9 and the lower rubber pad 5 are fitted together. The open end of the papermaking wire roll 1 passes through the frame 2. Both the left and right ends of the papermaking wire roll 1 are laid flat inside the cavity 3 and close to the inner wall. Pulling the open end of the papermaking wire roll 1 through the upper cavity 3 of the frame 2... At the bottom, opening the electric push rod 7 lowers the metal groove 8, causing the upper rubber pad 9 to press down and press the pulled-out papermaking wire against the lower rubber pad 5. Simultaneously, the pressing rod 10 presses the edge of the papermaking wire against the bottom of the cavity 3. Notably, the lower end of the upper rubber pad 9 is also equipped with anti-slip teeth 6, which are staggered with the anti-slip teeth 6 on the lower rubber pad 5. These anti-slip teeth 6 embed into the mesh of the papermaking wire, providing a relatively ideal anti-slip effect and preventing the papermaking wire from falling off during pulp dewatering. Furthermore, due to the elasticity of the rubber material, in... The fixed papermaking wire will not break due to friction and vibration during use. In addition, when it is necessary to replace the papermaking wire in the frame 2, the fixing of the papermaking wire is released by opening the electric push rod 7, which drives the upper rubber pad 9 and the pressure rod 10 to rise. Then, the papermaking wire roll 1 is pulled out to remove the worn part. The fixed wire is then fixed again by the above operation. The worn part can be removed with a cutting tool. The operation is simple and quick, which greatly improves the replacement efficiency. Especially in case of unexpected situations, it can greatly reduce the replacement time and ensure the production efficiency of the papermaking machine.

[0019] Please refer to Figures 1 and 2. L-shaped positioning plates 11 are fixedly installed on both the left and right sides of the lower end of the frame 2. Evenly distributed electric push rods 12 are fixedly installed through and on the lower end of each L-shaped positioning plate 11. An adjusting frame 13 is fixedly installed between the upper ends of the electric push rods 12. Composite spring groups 14 are fixedly installed at the four corners of the upper end of the adjusting frame 13. A vibration frame 15 is fixedly installed between the upper ends of the composite spring groups 14. Evenly distributed spherical hinges 16 are fixedly installed in the middle position of the upper end of the adjusting frame 13. An amplitude transformer 17 is fixedly connected to the ball joint of the spherical hinge 16. The upper end of the amplitude transformer 17 is fixedly connected to the vibration frame 15. The amplitude transformer 17 is electrically connected to the ultrasonic generator. By opening the electric push rods 12... 2. The extension end of the device drives the adjustment frame 13 to rise, which in turn drives the vibration frame 15 to rise. The vibration frame 15 stops when it is in contact with the lower end of the papermaking wire. After the ultrasonic generator is turned on, the vibration frame 15 generates high-frequency mechanical vibration through the amplification effect of the amplitude rod 17 and the flexibility of the spherical hinge 16. This high-frequency vibration is then applied to the papermaking wire through the vibration frame 15, which can generate micron-level amplitude, destroy the adhesion between the pulp particles and the wire, and keep the fine fibers in a suspended state, reducing the contact area with the mesh, thus effectively preventing clogging. Experiments show that the vibration energy can promote the directional arrangement of the limiting components, forming a uniform void structure, which greatly improves the dewatering efficiency.

[0020] Working principle: In use, the open end of the papermaking wire roll 1 is pulled out and passes through the bottom of the inner cavity 3 of the machine frame 2. By opening the electric push rod 7, the metal groove 8 is lowered, which causes the upper rubber pad 9 to press down and press the pulled-out papermaking wire against the lower rubber pad 5. At the same time, the pressing rod 10 also presses the edge of the papermaking wire against the bottom of the inner cavity 3. It is worth mentioning that the lower end of the upper rubber pad 9 is also provided with anti-detachment teeth 6, which are staggered with the anti-detachment teeth 6 on the lower rubber pad 5. Thus, the anti-detachment teeth 6 are embedded into the mesh of the papermaking wire. In addition, when it is necessary to replace the papermaking wire in the machine frame 2, the electric push rod 7 is opened to drive the upper rubber pad 9 and the pressing rod 10 to press down and press the metal groove 8. The pressure rod 10 is raised to release the papermaking wire from its fixation. Then, the papermaking wire roll 1 is pulled out completely after the worn part is removed. The worn part is then fixed again through the above operation. The worn part can be removed with a cutting tool. Further, the electric push rod 12 is opened so that its telescopic end drives the adjusting frame 13 to rise. The rising of the adjusting frame 13 drives the vibrating frame 15 to rise. The vibrating frame 15 stops when it is in contact with the lower end of the papermaking wire. After the ultrasonic generator is turned on, the amplification effect of the amplitude rod 17 and the flexibility of the spherical hinge 16 cause the vibrating frame 15 to generate high-frequency mechanical vibration. Finally, the high-frequency vibration is applied to the papermaking wire through the vibrating frame 15.
