Description

Technical Field

[0001] The utility model belongs to the technical field of packaging bag processing equipment, in particular to a sealing machine for packaging bag processing. Background Art

[0002] Many sealing machines are difficult to meet the needs of large-scale production in terms of processing speed, especially when facing high-frequency and large-scale production tasks, their sealing speed often becomes a bottleneck. This problem is mainly due to the design and power limitation of the mechanical transmission system and heating system of the equipment. Secondly, the unstable sealing quality is also a major defect. Packaging bags of different materials and thicknesses have different requirements for sealing temperature and pressure. It is difficult for existing sealing machines to achieve precise control when adjusting temperature and pressure, resulting in poor sealing strength and sealing, and even loose or burning sealing. In response to these shortcomings, conventional countermeasures mainly include improving mechanical structure, improving the efficiency of transmission and heating systems; using high-precision temperature control and pressure control technology to enhance the stability of sealing quality. However, these methods also have significant disadvantages. Improving mechanical structure and adopting high-precision control technology often mean higher manufacturing costs and technical barriers, resulting in rising equipment prices and increasing investment pressure on enterprises. Although strengthening maintenance can extend the service life of equipment, it also requires more manpower and time, increasing the operating burden of enterprises. Therefore, we hope to design a sealing machine with a new structure to solve this problem. Utility Model Content
