Description

Technical Field

[0001] The invention relates to the technical field of tobacco silk making equipment, and in particular to a maintenance workbench and method for integrated cutting and tooth punching of a conveyor belt. Background Art

[0002] The belt conveyor in the silk-making workshop is an important and commonly used auxiliary equipment in the silk-making process of cigarette production. Its daily maintenance frequency gradually increases with the increase of service life, and the conveyor belt is increasingly toothed, glued, replaced and repaired. In the process of replacing and repairing the conveyor belt, the most common maintenance process is the four processes of cutting, toothing, gluing and installation and commissioning of the conveyor belt; among the four processes, cutting and toothing are the most critical. The size after cutting and the flatness of the end surface after toothing directly affect whether the overall length of the conveyor belt is suitable to meet the installation and adjustment requirements, and whether the toothed mouth of the conveyor belt is firm and reliable after the conveyor belt is glued, and there are no gaps. However, after the sudden break of the conveyor belt, the cutting and toothing process of the spliced ​​conveyor belt only relies on manual marking and cutting, and then the mobile conveyor belt toothing machine is used for toothing and then glued. In this process, the deviation of manual marking and cutting is large, and the cutting end surface is prone to unevenness, resulting in poor gluing effect after toothing and gaps. In addition, the mobile conveyor belt toothing machine has certain application range limitations and the equipment is expensive. In addition, in the daily equipment maintenance or maintenance and improvement process of the workshop, there is often a need to cut and utilize common conveyor belts or plates such as conveyor belts, scrapers, and plexiglass plates. However, the existing maintenance and cutting mode only relies on manual marking and then cutting with a cutting machine. This process is not only time-consuming and labor-intensive, but also has high safety risks. In addition, the flatness of the end surface cannot be effectively guaranteed after manual marking, which brings risks and inconveniences to the equipment operation and maintenance and improvement process. Based on this, the present invention designs an integrated maintenance workbench for conveyor belt cutting and toothing to solve the above-mentioned problems. Summary of the invention
