Description

Vertical cable-membrane device heat sealing machine

Technical field:

The invention relates to the technical field of cable-membrane processing, in particular to a heat-sealing machine for a longitudinal cable-membrane device.

Background technique:

The cable-membrane structure system originated from the tents (buildings composed of poles, ropes and animal skins) that humans lived in in ancient times. After the 1970s, with the emergence of high-strength, waterproof, light-transmitting and smooth-surfaced, easy-to-clean, anti-aging architectural membrane materials, coupled with the rapid development of engineering computing science, the cable-membrane architectural structural system has made a comeback and is now widely used in coastal tourism. , Expo, art, sports and other public buildings with large spaces. Tokyo Dome "Big Egg" in Japan, Denver's Tenssile Roof in the United States and Georgia Dome in Atlanta, The Millennium Dome on the Thames River in the United Kingdom ), are world-renowned landmark buildings built using the cable-membrane structure system. In addition, cable-membrane materials have begun to be used in high-rise building structural systems. In the design of the Arabian Tower Hotel, which is nearly 100 meters high, its front facade uses double-layer membrane surfaces instead of glass curtain walls. Cable-membrane buildings are easy to build, easy to dismantle, easy to relocate, easy to renew, make full use of sunlight, air, and integrate with the natural environment. It is the darling of the "green building system" in the 21st century.

The emergence of membrane structure provides architects with new options beyond the traditional architectural model. The membrane structure uses membrane materials instead of traditional building materials, and its weight is only one-thirtieth of traditional buildings. Moreover, the membrane structure can fundamentally overcome the difficulties encountered in the realization of traditional structures in large-span (unsupported) buildings, and can create a huge unobstructed visual space. Its shape is free and light, flame retardant, easy to manufacture, quick to install, energy saving, easy to use, safe to use and other advantages, so it is widely used all over the world. It is also worth mentioning that under the sunlight, the interior of the building covered by the film is filled with natural diffuse light, there is no strong contrast between the bright surface and the shadow, and the indoor space visual environment is open and harmonious. At night, the lights in the building illuminate the night sky through the membrane of the roof, and the shape of the building shows a dreamlike effect. This structural form is especially suitable for large stadiums, entrance corridors, sketches, public leisure and entertainment plazas, exhibition venues, shopping centers and other fields.

The suspended cable-membrane structure greenhouse is a new type of greenhouse structure that can replace the arch-structure greenhouse. It has good force-bearing capacity and ability to resist natural disasters, and its low cost is conducive to the realization of mechanized operations. Its core part, the suspended cable-membrane structure, is a complex composed of plastic film and pressure-bearing cables. The pressure-bearing cables are fixed on the entire plastic film by heat-sealing connection of a layer of plastic film belt and the entire film. However, there is currently no automatic processing equipment for the suspended cable-membrane structure. It can only be made by hand. It is completely ironed by hand with an electric iron. The quality is low, and the quality cannot meet the design requirements, which limits the popularization and application of suspended cable-membrane structure greenhouses.
