Description
Technical Field
[0001] The utility model relates to the field of heat insulation films, in particular to a production system for rare earth light conversion heat insulation films. Background Art
[0002] Under sunlight irradiation, heat continuously accumulates on the surface of the irradiated object, causing its surface temperature to continuously rise. In summer, the increase in the temperature of buildings leads to too high temperatures in the surrounding environment and indoors, increasing the power consumption of air conditioning for refrigeration.
[0003] With the rapid development of science and technology and social production, energy and the environment have become two major issues that attract increasing attention from the whole society, thus posing higher requirements for energy conservation and environmental protection. In addition to requiring high visible light transparency, the window glass, sunlight panels, transparent ceilings, and automotive glass of buildings also need to effectively isolate heat radiation energy. There is an urgent need for a material that is both transparent and heat-insulating to solve this problem.
[0004] Most of the existing heat insulation films adopt a composite structure of a PET explosion-proof layer, a heat insulation layer, and a UC scratch-resistant layer. The heat insulation film contains glass microspheres to improve the heat insulation effect. However, in the existing production system for heat insulation films, materials such as glass microspheres and silane coupling agents are usually mixed and extruded together and then stretched. During the stretching process, it is easy to cause the phenomenon that the glass microspheres are unevenly distributed on the film, and the uneven distribution of the glass microspheres on the film easily affects the performance of the film.
[0005] Based on this, the utility model provides a production system for rare earth light conversion heat insulation films, which can effectively avoid the phenomenon that the glass microspheres are unevenly distributed on the film. Summary of the Utility Model
[0006] An object of the utility model is to provide a production system for rare earth light conversion heat insulation films to solve the problem that the glass microspheres are unevenly distributed on the film.
[0007] This object is achieved by the following technical solutions:

[0009] In this system, the thin film is first prepared, and the thin film is already in a stretched state. Then, the glass microspheres are inlaid into the stretched thin film, avoiding the phenomenon that after the glass microspheres are mixed and added, stretching the thin film causes the microspheres inside to be unevenly distributed and affects the performance of the film.
[0010] Among them, the microbead feeding structure enables glass microbeads to enter the placement grooves on the microbead alignment mold. The first conveying structure conveys the microbead alignment mold with glass microbeads into the thin film on the second conveying structure, so that the glass microbeads are inlaid in the thin film.

A first detection structure and a first replenishment structure are provided on the detection area. A camera is provided at the lower end of the first detection structure. The first detection structure is used to obtain picture information of each horizontal row of placement grooves in the microbead alignment mold. The first replenishment structure is used to supplement glass microbeads into the placement grooves lacking glass microbeads in each horizontal row.
[0012] Preferably, the angle between the feeding section and the horizontal direction is 30 degrees.
[0013] Preferably, the conveying section of the microbead alignment mold includes an inlay section, and the inlay section is parallel to the thin film on the second conveying structure. After the glass microbeads enter the placement grooves, the microbead alignment mold is further conveyed to the thin film on the second conveying structure. The thin film contacts the placement grooves, and the glass microbeads in the placement grooves are inlaid on the thin film to complete the preparation.
[0014] Furthermore, the first replenishment structure sequentially includes a material storage area and a material discharging area from top to bottom. The material storage area is used to place glass microbeads. There are several pipes arranged side by side in the material discharging area. The pipes correspond to each horizontal row of placement grooves in the microbead alignment mold one by one. The first conveying structure drives the microbead alignment mold to move along the direction of its column. A first telescopic plate is provided at the upper end of the pipe. The first telescopic plate is used to open or close the opening at the upper end of the pipe. The inner diameter of the pipe is greater than or equal to the outer diameter of the glass microbead. The length of the lower end of the pipe is telescopic.
[0015] A second telescopic plate is provided inside the pipe. The second telescopic plate is used to open or close the opening inside the pipe.
[0016] Preferably, several adjusting plates are provided on the upper end surface of the material storage area of the first replenishment structure. The lengths of the several adjusting plates are telescopic and can move on the upper end surface. An adjusting rod with an adjustable length is provided between adjacent two adjusting plates.
[0017] Compared with the prior art, the utility model has the following advantages and beneficial effects:

[0036] The glass microbeads in the first heat-insulating film 1 are located on the same plane, which is the first plane; the glass microbeads in the second heat-insulating film 4 are located on the same plane, which is the second plane; the glass microbeads in the third heat-insulating film 7 are located on the same plane, which is the third plane; the first plane, the second plane and the third plane are parallel to each other.
[0037] In this embodiment, the arranging device is as Figure 1 shown. The arranging device includes a first conveying structure 10, a second conveying structure 11 and a microbead feeding structure. A microbead arranging die 12 is arranged on the first conveying structure 10.
[0038] A number of placing grooves are arranged on the microbead arranging die 12. The size of the placing grooves is greater than or equal to the diameter of the glass microbeads in the first heat-insulating film 1 or the second heat-insulating film 4 or the third heat-insulating film 7. Moreover, the size of the microbead arranging die 12 and the size and spacing of the placing grooves are adjusted as required.
[0039] The microbead arranging die 12 is placed on the first conveying structure 10 and is conveyed by the first conveying structure 10. The second conveying structure 11 is used to heat and convey the first film or the second film or the third film; the microbead feeding structure places the microbeads on the microbead arranging die 12; after the microbeads are on the microbead arranging die 12, the first conveying structure 10 conveys the microbead arranging die 12 with microbeads to the first film or the second film or the third film on the second conveying structure 11. The conveying section of the microbead arranging die 12 includes an inlay section, and the inlay section is parallel to the film on the second conveying structure 11.
[0040] When the microbead arranging die 12 is placed on the first conveying structure 10, it includes a conveying section and a feeding section.

The baffle 14 is located between the placing plate 13 and the feeding section of the microbead arranging die 12. The feeding pipe 15 is located in the feeding area. The glass microbeads enter between the placing plate 13 and the feeding section through the feeding pipe 15 and contact the feeding section of the microbead arranging die 12. The feeding section of the microbead arranging die 12 fills the placing grooves in the microbead arranging die 12 with glass microbeads during the moving process.

[0045] The first replenishment structure 18 is a rectangular cavity. A plurality of pipes 181 arranged side by side are provided in the rectangular cavity. The pipes 181 in the first replenishment structure 18 correspond one by one to the placement grooves in each horizontal row of the microbead arrangement mold 12.

[0053] When the glass beads are located in the material storage area, the glass beads correspond one by one to the upper ends of the pipes 181. When one of the pipes needs to be replenished with glass beads, the first telescopic plate 183 and the second telescopic plate 182 on the pipe 181 are opened, so that the glass beads enter the pipe and are located on the corresponding placement groove above.
[0054] In some embodiments, a plurality of adjusting plates 185 are provided on the upper end surface 184 of the first supplementary structure 18. The lengths of the plurality of adjusting plates 185 are telescopic and can move on the upper end surface 184.
