Description

Quick roll changing structure for paper machine Technical Field The utility model relates to the technical field of quick roll changing for paper machines, in particular to a quick roll changing structure for a paper machine. Background In the field of contemporary paper industry production, a paper machine is used as core equipment, the operation efficiency and stability of the paper machine are directly related to the production capacity and the product quality of enterprises, a roller assembly in the paper machine is a key component of the whole equipment and is responsible for a plurality of process functions such as paper transmission, pressing, drying and the like, however, a roller replacing structure of the paper machine in the prior art exposes serious functional defects in the practical application process, and particularly, the key link of the installation and the disassembly of the roller assembly is realized. In order to meet the increasing production efficiency requirements and diversified paper type conversion requirements of the modern paper industry, the paper machine needs to realize the quick replacement of the roller assemblies in different production working conditions so as to adapt to the process adjustment and equipment maintenance requirements, but the roller replacement structure of the paper machine in the prior art has obvious limitations in the aspects of mounting and dismounting the roller assemblies, and cannot realize convenient and efficient operation, in particular, the traditional roll changing mode needs to assist in the operation process by means of various specialized tools such as lifting equipment, wrenches and jacks, the operation flow is complex, the series of operations consume a large amount of time and manpower resources, higher requirements are also put forward on the specialized skills of operators, and under the high-strength production environment, the overall production continuity is seriously influenced by the complex roll assembly changing operation, so that the equipment downtime is prolonged and the production efficiency is reduced.
