Description

Technical Field

[0001] The present invention relates to the field of corrugated production equipment, specifically a modular quick-disassembly and assembly type corrugating roll. Background Art

[0002] As a key component of a corrugated board machine, the performance of the corrugating roll directly affects the production efficiency and product quality of corrugated board. During the use of traditional corrugating rolls, due to long-term exposure to high temperature, high pressure and surface abrasion, the tungsten carbide wear-resistant layer is prone to breakage and peeling, thus shortening the service life of the corrugating roll. In addition, when replacing the corrugated teeth of traditional corrugating rolls, a complex disassembly and assembly process is often required, which not only consumes time and effort but also increases the maintenance cost.

[0003] Specific limitations of traditional corrugating rolls Integral design leads to high maintenance costs and long downtime Traditional corrugating rolls are usually of integral design. Once a certain part is damaged or worn, the entire corrugating roll needs to be replaced. This not only increases the maintenance cost but also results in a long downtime, seriously affecting the production efficiency.

[0004] During maintenance, the entire corrugating roll needs to be removed from the equipment and then replaced or repaired, with complex and time-consuming operations.

[0005] Complex disassembly and assembly process The structure of the integral corrugating roll is relatively complex, and the disassembly and assembly process is cumbersome. Usually, professional technicians and special tools are required, increasing the maintenance difficulty and cost.

[0006] Problems such as insecure connection and looseness are likely to occur during the disassembly and assembly process, affecting the stability and reliability of the corrugating roll.

[0007] Poor adaptability The design of traditional corrugating rolls is fixed, making it difficult to flexibly adjust their length and functions according to different production requirements, restricting the applicable range of the equipment.

[0008] The production requirements of different types of corrugated boards vary, but traditional corrugating rolls cannot quickly adapt to these changes, reducing the flexibility and efficiency of the production line. Summary of the Invention
