Problems solved by technology
However, since the heating sheet in the heat sealing grid on the direct heating heat sealing machine needs to be replaced frequently, it is not very convenient to replace the heating sheet of different sizes at the same time, which affects the heat sealing welding efficiency
During the heating process of the heating sheet, due to thermal expansion, there will be a certain amount of elongation, so the heating surface will no longer be completely flat, which will affect the quality of heat sealing welding
The heating system needs to cool down after the heat-sealing temperature is maintained for a certain period of time to shape the heat-sealing film material. Therefore, a cooling system is required. At present, cooling water is commonly used in the support structure to cool down, which makes the whole heat-sealing equipment more complicated. , which increases the cost of the heat sealing machine, and the circulation of cooling water near the electrified body also affects the safety of the heat sealing machine

Description
technical field [0001] The invention relates to the field of heat sealing and welding of polymer film materials and composite film materials, in particular to an air-cooled heat sealing grid and a heat sealing machine. Background technique [0002] In the packaging industry and clothing industry, the extensive use of polymer film materials and composite film materials has led to the development of heat sealing welding technology. In the aerostat industry, the main materials for flexible aerostats are polymer film materials and composite film materials. The film materials are cut and finally need to be heat-sealed and welded to form them. Therefore, the heat sealing machine has also become the main processing equipment in the flexible aerostat manufacturing industry, and the heat sealing welding has also become the main processing method in the flexible aerostat manufacturing industry. [0003] In the field of heat sealing and welding, the main heat sealing equipment is high...
