Description

Heat insulation structure and production line thereof Technical Field The invention relates to the field of profile manufacturing, in particular to a heat insulation structure and a production line thereof. Background In the fields of construction, automobiles, household appliances and the like, the heat insulation structure is a key component for realizing energy conservation and improving the use comfort. At present, the heat insulation structure on the market mostly adopts a combination mode of single sectional material and heat insulation strips, the heat insulation strips are usually solid structures or are only filled with common heat insulation materials (such as polyurethane foam, glass wool and the like), and the structures have obvious heat insulation performance short plates. The heat conductivity coefficient of the common heat insulation material is higher, the requirements of high-end scenes on low heat conduction and high-efficiency heat insulation are difficult to meet, and particularly in the fields of building doors and windows, cold chain equipment and the like with severe requirements on heat insulation effect, the problems of excessively fast heat conduction and excessively high energy consumption are easy to occur. Meanwhile, in the existing heat insulation structure, the problem that the joint part of the section bar and the heat insulation strip is not tight in fit and too large in gap often exists, and the heat bridge formed at the gap can further weaken the whole heat insulation effect. In addition, for pursuing the heat-proof quality, part structure excessively increases insulating layer thickness, leads to overall structure volume increase, weight increase, and the suitability reduces, and assembly complexity promotes, is unfavorable for mass production. Aerogel is used as a high-efficiency heat insulation material with extremely low heat conductivity coefficient, and although the aerogel is gradually applied to the field of heat insulation, the application form of the aerogel in the prior art is single, and most of the aerogel is wholly coated or simply filled, so that the structural characteristics of the profile cannot be fully combined to realize accurate adaptation. For example, the aerogel is directly smeared on the surface of the section bar in a part of the structure, so that the problems of falling and breakage are easy to occur, and in the part of the filling structure, the degree of adhesion of the aerogel, the section bar and the heat insulation strip is insufficient, a heat conduction channel still exists, and the heat insulation advantage of the aerogel cannot be fully exerted. Therefore, a heat insulation structure with reasonable structural design, excellent heat insulation performance and stable assembly and a production line thereof are needed to solve the defects in the prior art. Disclosure of Invention Based on the above, in order to solve the problems, the invention provides a heat insulation structure and a production line thereof, and the specific technical scheme is as follows: an insulation structure comprising The first section bar is provided with a first C-shaped groove, and a first aerogel sheet is covered in the first C-shaped groove; The heat insulation strip is provided with a through cavity penetrating through the heat insulation strip, and aerogel is arranged in the through cavity; the third section bar, be equipped with the second C type groove on the third section bar, the second C type inslot covers there is the second aerogel piece, the one end in second type groove inserts and locates in the first C type inslot and with first aerogel piece laminating, the other end in second type groove inserts and locates in the second C type inslot and with the laminating of second aerogel piece. According to the heat insulation structure, the aerogel material is used as a core heat insulation medium, the first aerogel piece is arranged in the first C-shaped groove of the first section bar, the second aerogel piece is arranged in the second C-shaped groove of the third section bar, meanwhile, the aerogel piece is arranged in the through cavity of the heat insulation bar, so that a three-section aerogel heat insulation system is formed, the aerogel itself has extremely low heat conductivity and is matched with a multi-position and all-directional arrangement mode, the heat conduction path between the first section bar, the heat insulation bar and the third section bar can be effectively blocked, compared with the traditional solid heat insulation bar or common filling material structure, the heat insulation performance is improved remarkably, the heat insulation requirement of a high-end scene can be met better, the energy loss is reduced, one end of the heat insulation bar is inserted into the first C-shaped groove and is attached to the first aerogel piece, the other end is inserted into the second C-shaped groove and is attached to the second aerogel pie
