Description

Technical Field

[0001] The utility model relates to the technical field of production equipment for bubble aluminum thermal insulation film blankets, in particular to a production device for polyvinyl fluoride flame-retardant bubble aluminum thermal insulation film blankets. Background Art

[0002] The bubble aluminum insulation blanket effectively prevents heat transfer through the reflective effect of the aluminum foil and the heat insulation effect of the bubble layer.

[0003] After searching, patent publication number CN213291613U discloses a high-stability bubble aluminum thermal insulation blanket, including a tetrafluoroethylene cast layer, the upper end face of the tetrafluoroethylene cast layer is fixedly connected to an upper bubble layer, the two sides of the upper shock-resistant layer are fixedly connected to upper buffer columns, the upper end face of the upper aluminum foil layer is fixedly connected to an upper anti-corrosion treatment layer, the two sides of the lower shock-resistant layer are fixedly connected to lower buffer columns, and the lower end face of the lower aluminum foil layer is fixedly connected to a lower anti-corrosion treatment layer. This high-stability bubble aluminum thermal insulation blanket achieves a balance of air pressure between the layers of the bubble aluminum thermal insulation blanket, can prevent the formation of bubbles inside the bubble aluminum thermal insulation blanket, ensures the aesthetics of the bubble aluminum thermal insulation blanket, improves the cold and heat resistance of the bubble aluminum thermal insulation blanket, and greatly improves the shock resistance of the bubble aluminum thermal insulation blanket through the inner and outer double-layer bubble nano-buffering technology, thereby avoiding deformation and damage of the bubble aluminum thermal insulation blanket caused by impact and stretching, and ensuring the service life of the bubble aluminum thermal insulation blanket.

[0004] The above patents have obvious beneficial effects, but still have the following deficiencies in actual operation:

[0005] The cast layer of the bubble aluminum thermal insulation blanket in the above-mentioned comparative document adopts a tetrafluoroethylene cast layer. However, due to the high hardness of tetrafluoroethylene, it is relatively difficult to process. Therefore, in reality, polyvinyl fluoride (PVF) is used as the material to make the cast layer of the bubble aluminum thermal insulation blanket. Polyvinyl fluoride (PVF) is a high-performance fluoroplastic with many excellent physical and chemical properties. Polyvinyl fluoride has excellent weather resistance and can resist sunlight, chemical solvents, acid and alkali corrosion, moisture and oxidation. It is not easy to age after long-term use. It has the characteristics of slow burning to self-extinguishing and high safety. Therefore, polyvinyl fluoride is added as a material in the production of the bubble aluminum thermal insulation blanket. The flow layer improves the flame retardant effect of the bubble aluminum thermal insulation blanket. A calendering device is required for the production of polyvinyl fluoride. In the existing technology, polyvinyl fluoride is calendered by two symmetrical calendering rollers. However, due to the uneven thickness of the polyvinyl fluoride layer before the actual calendering process, the amount of stock between the calendering rollers is too much or too little. Completing the calendering at one time may affect the uniformity of the thickness, resulting in the thickness of the calendered polyvinyl fluoride layer being also uneven, reducing the quality of the bubble aluminum thermal insulation blanket after production. Therefore, this field urgently needs to improve the production device of the polyvinyl fluoride flame retardant bubble aluminum thermal insulation blanket, so as to solve the defects of the existing technology.

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0029] See also Figure 1-Figure 7 A polyfluoroethylene flame-retardant bubble aluminum insulation film blanket production device comprises a calendering box 1, with an inlet 2 and an outlet 3 at both ends of the calendering box 1 respectively provided, two rows of horizontal lower calendering rollers 4 and upper calendering rollers 5 are rotatably connected in the calendering box 1, and lower transmission shafts 9 rotatably connected to the calendering box 1 are fixedly installed at both ends of the lower calendering roller 4, and upper transmission shafts 10 are fixedly installed at both ends of the upper calendering roller 5. A driving unit 6 for simultaneously driving several lower transmission shafts 9 to rotate is provided on one side of the calendering box 1, and a synchronous transmission unit 7 is provided between every two upper transmission shafts 10 and the lower transmission shaft 9. An adjusting unit 8 for adjusting the height position of several upper calendering rollers 5 is provided on the upper part of the calendering box 1. The spacing between each lower calendering roller 4 and the upper calendering roller 5 can be adjusted. They are arranged from the inlet 2 to the outlet 3, and the spacing between the lower calendering roller 4 and the upper calendering roller 5 decreases in an arithmetic progression.

[0030] Specifically, when producing the polyvinyl fluoride flame retardant bubble aluminum insulation film blanket, one end of the prepared polyvinyl fluoride film is inserted between a plurality of lower calendering rollers 4 and an upper calendering roller 5, and the spacing between the plurality of lower calendering rollers 4 and the upper calendering rollers 5 is adjusted by the adjustment unit 8, and the plurality of lower calendering rollers 4 and the upper calendering rollers 5 are arranged from the inlet 2 to the outlet 3, and the spacing between the lower calendering rollers 4 and the upper calendering rollers 5 decreases in an arithmetic progression, and the driving unit 6 is turned on, and the driving unit 6 simultaneously drives a plurality of lower transmission shafts 9 to rotate, and the plurality of lower transmission shafts 9 drive the upper transmission shaft 10 to rotate through the transmission unit 7, and the plurality of lower calendering rollers 4 and the upper calendering rollers 5 rotate simultaneously and synchronously, and the polyvinyl fluoride film is subjected to the heat treatment. The polyvinyl fluoride film is conveyed and calendered gradually to prevent the thickness of the calendered polyvinyl fluoride film from being uneven, thereby improving the quality of the calendered polyvinyl fluoride film. Subsequently, the aluminum bubble layer is compounded on both sides of the polyvinyl fluoride film through a composite device. Since polyvinyl fluoride has the characteristics of slow burning and self-extinguishing, it has a flame retardant effect, thereby improving the production quality of the polyvinyl fluoride flame retardant bubble aluminum insulation film blanket. Several lower calendering rollers 4 and upper calendering rollers 5 rotate synchronously, which also has the effect of improving the quality of the polyvinyl fluoride film after calendering, and polyvinyl fluoride films of different thicknesses can be calendered, thereby improving the scope of application of the polyvinyl fluoride flame retardant bubble aluminum insulation film blanket in production.

[0031] As a technical optimization solution of the present invention, the drive unit 6 includes a drive motor 11 fixedly installed on one side of the calendering box 1, and the output end of the drive motor 11 is fixedly connected to the end of one of the lower transmission shafts 9. A transmission wheel 12 is fixedly installed on the side surface of the outer end of each lower transmission shaft 9, and a transmission belt 13 for transmission is sleeved between the sides of adjacent transmission wheels 12.

[0032] Specifically, the drive motor 11 is started, and the output end of the drive motor 11 drives one of the lower transmission shafts 9 to rotate. The lower transmission shaft 9 drives the other lower transmission shafts 9 to rotate at the same time through the cooperation of the transmission belt 13 and the transmission wheel 12, thereby achieving the effect of synchronous rotation of several lower transmission shafts 9.

[0033] As a technical optimization solution of the present invention, each group of transmission units 7 includes a U-shaped fixed frame 14 arranged on one side of the calendering box 1, and a cylindrical gear 15 is rotatably connected to the relative side wall of the fixed frame 14. The lower transmission shaft 9 and the upper transmission shaft 10 are fixedly installed with an adaptive rotating disk 16 on the side of the outer end, and the two rotating disks 16 are fixedly connected to the side of a circular gear ring 17 that is circular and meshes with the cylindrical gear 15.

[0034] Specifically, when the lower transmission shaft 9 rotates, the rotating disk 16 and the circular gear ring 17 on its side are driven to rotate, and the cylindrical gear 15 connected to the fixed frame 14 is driven to rotate, thereby driving the rotating disk 16 and the circular gear ring 17 located on the side of the upper transmission shaft 10 to rotate, thereby achieving the synchronous and opposite rotation of the lower calendering roller 4 and the upper calendering roller 5, and the polyvinyl fluoride film is calendered and the conveying effect is started at the same time. At the same time, through the arrangement of the cylindrical gear 15, the rotating disk 16 and the circular gear ring 17, the synchronous rotation of the lower calendering roller 4 and the upper calendering roller 5 will not be affected when the height of the upper calendering roller 5 is adjusted.

[0035] As a technical optimization solution of the present invention, each group of adjustment units 8 includes a moving block 18 rotatably connected to the side of the upper transmission shaft 10, and a moving groove 19 adapted to the moving block 18 is opened on the side of the calendering box 1. A first adjusting rod 20 passes through and is rotatably connected to the upper part of the calendering box 1. The first adjusting rod 20 passes through the moving block 18 and is threadedly connected to it. The upper end side of the first adjusting rod 20 is threadedly connected to a first limiting nut 21 for limiting. Several scales 27 adapted to the moving groove 19 are fixedly installed on the side of the calendering box 1.

[0036] Specifically, when it is necessary to adjust the distance between the upper calendering roller 5 and the lower calendering roller 4, the first adjusting rod 20 is rotated. When the first adjusting rod 20 rotates, it drives the moving block 18 located in the moving groove 19 to move, and the moving block 18 drives the upper transmission shaft 10 to move, thereby achieving the effect of adjusting the distance between each group of upper calendering rollers 5 and the lower calendering roller 4. At the same time, the adjustment position between each group of upper calendering rollers 5 and the lower calendering roller 4 can be intuitively viewed according to the scale on the ruler 27. After the position of the upper calendering roller 5 is adjusted, the first limit nut 21 is tightened to limit and fix the position of the first adjusting rod 20.

[0037] As a technical optimization solution of the present invention, a number of fixed plates 22 adapted to the fixed frame 14 are fixedly installed on one side of the calendering box 1, a sliding block 23 is fixedly installed on one side of the fixed frame 14, and a sliding groove 24 adapted to the sliding block 23 is opened on one side of the fixed plate 22. A second adjusting rod 25 passes through and is rotatably connected to the upper side of the fixed plate 22. The second adjusting rod 25 passes through the sliding block 23 and is threadedly connected to it. The upper end side of the second adjusting rod 25 is threadedly connected to a second limiting nut 26 for limiting.

[0038] Specifically, when calendering polyvinyl fluoride films of different thicknesses, the position of the upper calendering roller 5 needs to be adjusted. When adjusting the upper calendering roller 5, when the rotating disk 16 and the circular gear ring 17 on its side move a long distance, the position of the cylindrical gear 15 needs to be adjusted to ensure the transmission effect of the cylindrical gear 15 on the two circular gear rings 17. At this time, by rotating the second adjusting rod 25, the second adjusting rod 25 drives the sliding block 23 located in the sliding groove 24 to move when it rotates, and the sliding block 23 drives the fixed frame 14 to move, thereby realizing the position adjustment of the cylindrical gear 15 and improving the applicability of the overall device.

[0039] Among them, the above-mentioned drive motor 11 can be purchased on the market. It is a mature technology and has been fully disclosed, so it is not repeated in the specification. The drive motor 11 is equipped with a power connection line, and it is electrically connected to the external main controller and 220V phase voltage (or 380V line voltage) through the power line, and the main controller can be a conventional known device such as a computer that plays a control role.
