Description

Technical Field

[0001] The present invention relates to the technical field of refrigeration film production, and in particular to a production device and method for a high-efficiency radiation refrigeration film. Background Art

[0002] Radiative cooling refers to a novel refrigeration technology that transfers heat from a heat source to a cold source in outer space through the atmospheric window of infrared radiation (the atmosphere has a high transmittance for thermal radiation in the 8-13 μm wavelength range, with an average transmittance of 85%). Traditional refrigeration technologies typically consume energy and resources to remove heat, while radiative cooling passively enhances the Earth's natural cooling process. Radiative cooling offers the advantages of zero energy consumption, zero pollution, and no moving parts. It has positive implications for energy conservation and environmental protection, and can be widely used to cool buildings and objects, including factories, cool storage facilities, automobiles, solar photovoltaic equipment, electronic equipment, cryogenic storage tanks, and outdoor equipment.

[0003] Currently, when producing radiant cooling film, the produced radiant cooling film needs to be transported to a cutting device using rollers to be cut into small pieces for subsequent lamination with glass of the same size. However, during the process of being transported to the cutting device, the tension applied to the radiant cooling film by the two sides of the roller is different, which can easily cause the edges of the radiant cooling film to be flanging, resulting in an uneven cut surface during subsequent cutting. In addition, the flanging at the edges of the radiant cooling film affects the flatness of the subsequent lamination. Summary of the Invention

[0015] The present invention also provides a method for producing a high-efficiency radiation cooling film, which is applied to a production device for a high-efficiency radiation cooling film. The method for producing a high-efficiency radiation cooling film comprises the following steps:

[0016] Step S1: The radiant cooling film to be transported is placed inside the transport cover and pressed against the inside of the flat recess by a cleaning roller. When the radiant cooling film is transported, the driving component drives the cleaning roller to clean it and simultaneously drives the transport component to reciprocate, thereby intermittently transporting the radiant cooling film to one side at equal distances. Before transporting, the feedback control component is triggered to cause the transport component to adsorb and fix the radiant cooling film, making transport more stable.

[0017] Step S2: When the drive assembly is working, the swing arm rotates, driving the slider to slide back and forth up and down inside the waist-shaped frame, thereby driving the waist-shaped frame to slide back and forth horizontally, causing the slider to slide back and forth inside the slideway. When the slider slides to one side of the slideway, it triggers the feedback control assembly to operate. When it slides to the other side of the slideway, it releases the adsorption of the consignment assembly on the radiant cooling film. At the same time, when the slider slides, it drives the driven gear to rotate through the rack, thereby driving the cleaning roller to clean the transported radiant cooling film.

[0018] Step S3: When the shipping component is working, the radiant cooling film is attached to the inside of the flat recess on the top of the pallet. When the slider slides to one side of the slide, the feedback control component is triggered. Under the action of the negative pressure adsorption force generated by the vacuum generator, the air inside the air cavity can be sucked into the through hole through the bent flow channel, and then enter the buffer cavity through the through hole, and finally enter the vacuum generator through the filter port and the air intake channel. At this time, the inside of the air cavity is in a vacuum adsorption state, and the bottom of the radiant cooling film can be adsorbed and fixed;

[0019] Step S4: When the feedback control component is working, when the limit block is pushed into the storage groove, the cylindrical block will be pushed into the cylindrical cavity through the connecting rod. During the pushing process, the bending plate will be driven to slide toward the side of the cylindrical cavity. Since the end of the bending plate extending to the inside of the conveying cover is longer, when the slide bar pushes the limit block into the storage groove, one end of the bending plate can still extend to the top of the pressure plate, pressing the pressure plate downward, and the negative pressure adsorption force generated by the auxiliary vacuum generator will adsorb the damping plate downward.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The present invention places the radiant cooling film to be transported inside the conveying cover and presses the radiant cooling film against the inside of the flat recess via a cleaning roller. During the transport of the radiant cooling film, the driving assembly drives the cleaning roller to clean it, while simultaneously driving the transport assembly to reciprocate, thereby intermittently transporting the radiant cooling film to one side at equal intervals. Before transport, the feedback control assembly is triggered to cause the transport assembly to adsorb and secure the radiant cooling film, making transport more stable.

[0022] 2. In the present invention, when the drive assembly is in operation, an external power source drives the driving gear to rotate. The rotation of the driving gear drives the swing arm to rotate. When the swing arm rotates, it drives the slider to slide back and forth up and down inside the waist-shaped frame, thereby driving the waist-shaped frame to slide back and forth horizontally, so that it drives the slide bar to slide back and forth inside the slideway. When the slide bar slides to one side of the slideway, it triggers the feedback control assembly to operate. When it slides to the other side of the slideway, it releases the adsorption of the consignment assembly on the radiant cooling film. At the same time, when the slide bar slides, it drives the driven gear to rotate through the rack, thereby driving the cleaning roller to clean the transported radiant cooling film.

[0023] 3. In the present invention, when the consignment assembly is working, the radiant cooling film is attached to the inside of the flat recess on the top of the support plate. When the slide slides to one side of the slide, the feedback control assembly will be triggered, and one end of the slide will push the limit block to the inside of the storage groove. At this time, the limit block releases the constraint on the ejector pin, and under the elastic force of the jacking spring, the reciprocating block will be pushed to the top of the reciprocating cavity, so that the filter port is opposite to the air intake duct. At this time, the top of the ejector pin extends to the bottom end of the bent flow channel. Under the action of the negative pressure adsorption force generated by the vacuum generator, the air inside the air cavity can be sucked into the through hole through the bent flow channel, and then enter the buffer cavity through the through hole, and finally enter the vacuum generator from the filter port and the air intake duct. At this time, the inside of the air cavity is in a vacuum adsorption state, and the bottom of the radiant cooling film can be adsorbed and fixed.

[0024] 4. In the present invention, when the feedback control component is working, when the limit block is pushed into the storage groove, the cylindrical block will be pushed into the cylindrical cavity through the connecting rod. During the pushing process, the bending plate will be driven to slide toward one side of the cylindrical cavity. Since the end of the bending plate extending to the inside of the conveying cover is longer, when the slide bar pushes the limit block into the storage groove, one end of the bending plate can still extend to the top of the pressure plate, pressing the pressure plate downward, and the negative pressure adsorption force generated by the auxiliary vacuum generator will adsorb the damping plate downward.

A cleaning roller 16 is rotatably provided between the front and rear inner walls of the conveying cover 1, and one end of the cleaning roller 16 is fixed to one side of the driven gear 12.

[0037] The effect achieved is that the radiation cooling film to be transported is placed inside the conveying cover 1, and the radiation cooling film is pressed inside the flat recess 26 through the cleaning roller 16. When the radiation cooling film is transported, the driving component can drive the cleaning roller 16 to clean it, and at the same time drive the consignment component to reciprocate, so that the radiation cooling film can be intermittently transported to one side at equal distances. Before transportation, the feedback control component will be triggered to allow the consignment component to adsorb and fix the radiation cooling film, making the transportation more stable.

[0038] like Figure 1 、 Figure 2 and Figure 3 As shown, the driving assembly includes a slide bar 9, which is slidably connected to the inside of the slide 3, and the bottom of the slide bar 9 is sealed with the inner bottom surface of the slide 3, and a rack 10 is provided on the top of the slide bar 9, which meshes with the driven gear 12.

A slider 8 is slidably provided between the inner walls on both sides of the waist-shaped frame 7, and the other end of the rocker bar 6 is rotatably connected to the front side of the slider 8.

[0039] The effect achieved is that the driving gear 5 is driven to rotate by an external power facility, and the rotation of the driving gear 5 will drive the rocker arm 6 to rotate. When the rocker arm 6 rotates, it will drive the slider 8 to slide back and forth up and down inside the waist-shaped frame 7, and then drive the waist-shaped frame 7 to slide horizontally back and forth, so that it drives the slide bar 9 to slide back and forth inside the slide 3. When the slide bar 9 slides to one side of the slide 3, it will trigger the feedback control component to work. When it slides to the other side of the slide 3, it will release the adsorption of the consignment component on the radiation refrigeration film. At the same time, when the slide bar 9 slides, it will drive the driven gear 12 to rotate through the rack 10, and then drive the cleaning roller 16 to clean the transported radiation refrigeration film.

[0040] like Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 7 and Figure 8As shown, the consignment assembly includes a support plate 17, which is located on the inner side of the conveying cover 1, and the front side of the support plate 17 and the rear side of the slide bar 9 are fixed to each other, and the rear side of the support plate 17 is slidably fitted between the inner wall of the rear side of the conveying cover 1, and a flat recess 26 is provided on the top of the support plate 17 to penetrate to both sides, and an air cavity 20 is provided inside the support plate 17, and a plurality of through-holes 21 are equidistantly provided on the inner bottom surface of the flat recess 26 to penetrate into the interior of the air cavity 20, and a supporting filter 22 is provided between the inner walls of the plurality of through-holes 21 near the top edge, and a bending flow channel 13 is provided inside the slide bar 9, and one end of the bending flow channel 13 penetrates into the interior of the air cavity 20, and the other end of the bending flow channel 13 penetrates to the bottom of the slide bar 9, and an air inlet 14 is provided on the inner bottom surface of the slide 3, and one end of the air inlet 14 penetrates to the front side of the conveying cover 1, and the bending flow channel 13 is relatively conductive with the air inlet 14, and the support plate 17 is provided with a plurality of through-holes 21. A protrusion 40 is fixed at the two corners near one side of the top, and an inner cavity 41 is opened inside the two protrusions 40. A damping plate 42 is slidably set between the inner walls of the two inner cavities 41. A push rod 44 is fixed to the bottom of the two damping plates 42. The bottom of the two push rods 44 slides through to the bottom of the protrusion 40. A pressure plate 45 is fixed to the bottom of the two push rods 44. One end of the two pressure plates 45 extends to the inner side of the flat recess 26. A sponge pressure plate 25 is provided at the bottom of the two push rods 44 near one end edge. A throttling hole 43 that penetrates into the interior of the air cavity 20 is opened on the inner wall of one side of the two inner cavities 41 near the edge of the inner bottom surface. A U-shaped groove 23 is opened inside the interior of the support plate 17 near one edge, and a U-shaped frame 24 is provided inside the U-shaped groove 23. Both ends of the U-shaped frame 24 slide through to the top of the support plate 17 and are fixed to the bottom of the pressure plate 45.

[0041] The effect achieved is that the radiant cooling film is attached to the inside of the flat recess 26 on the top of the support plate 17. When the slide bar 9 slides to one side of the slide 3, the feedback control component will be triggered. At this time, one end of the air inlet 14 is attached to the bottom of the slide bar 9, and one end of the air inlet 14 is closed by the bottom of the slide bar 9. One end of the slide bar 9 will push the limit block 32 to the inside of the storage groove 31. At this time, the limit block 32 releases the constraint on the ejector pin 38. Under the elastic force of the lifting spring 36, the reciprocating block 34 will be pushed to the top of the reciprocating cavity 33, so that the filter port 37 is opposite to the air intake duct 15. At this time, the top of the ejector pin 38 extends to the bottom end of the bending flow channel 13. Under the action of the negative pressure adsorption force generated by the vacuum generator 2, the air inside the air cavity 20 can be sucked into the through hole 39 through the bent flow channel 13, and then enter the buffer cavity 35 through the through hole 39, and finally enter the vacuum generator 2 through the filter port 37 and the air intake duct 15. At this time, the air cavity 20 is in a vacuum adsorption state, and the bottom of the radiation cooling membrane can be adsorbed and fixed. At the same time, the vacuum adsorption force inside the air cavity 20 is also transmitted to the inside of the inner cavity 41 through the throttling hole 43 to adsorb the damping plate 42 downward, thereby driving the push rod 44 and the pressure plate 45 to slide downward, so that the sponge pressing sheet 25 at one end of the pressure plate 45 presses the radiation cooling membrane.

[0042] like Figure 2 、 Figure 4 、 Figure 6 and Figure 8As shown, the feedback control component includes a cylindrical block 28, a cylindrical cavity 27 is provided on one side of the interior of the conveying cover 1 near the slide 3, the cylindrical block 28 is slidably connected between the inner walls of the cylindrical cavity 27, and a side opening 18 is provided on the rear side of the cylindrical cavity 27 that penetrates into the interior of the conveying cover 1, and a bending dial plate 19 is slidably provided inside the side opening 18, one end of the bending dial plate 19 is fixed on the outer surface of the cylindrical block 28, and the other end of the bending dial plate 19 is located inside the conveying cover 1 and opposite to the top of the pressure plate 45, a return spring 29 is fixed on one side of the cylindrical block 28, one end of the return spring 29 is fixed on the inner wall of the cylindrical cavity 27, a receiving groove 31 is provided on the inner wall of one side of the slide 3, and a connecting rod 30 is fixed on the other side of the cylindrical block 28, one end of the connecting rod 30 slides through the interior of the receiving groove 31, and a limiting block 32 is fixed on one end of the connecting rod 30. A reciprocating chamber 33 is provided inside the cover 1 near the bottom of the slide 3, and a reciprocating block 34 is slidably provided between the inner walls of the reciprocating chamber 33. A pin 38 that penetrates into the interior of the slide 3 is fixed to the top of the reciprocating block 34, and the top of the pin 38 fits with the bottom of the limit block 32. A buffer chamber 35 is provided inside the reciprocating block 34 near the bottom edge, and a through hole 39 that penetrates into the interior of the buffer chamber 35 is provided on the top of the pin 38.

A lifting spring 36 is fixed between the bottom of the reciprocating block 34 and the inner bottom surface of the reciprocating chamber 33. An air intake duct 15 is provided inside the conveying cover 1, and one end of the air intake duct 15 penetrates into the interior of the reciprocating chamber 33 and fits with the outer surface of the reciprocating block 34 near the top edge, and the other end of the air intake duct 15 is communicated with the vacuum generator 2.

[0043] The effect achieved is that when the limit block 32 is pushed into the receiving groove 31, the cylindrical block 28 will be pushed into the cylindrical cavity 27 through the connecting rod 30. During the pushing process, the bending plate 19 will be driven to slide toward the side of the cylindrical cavity 27. Since the end of the bending plate 19 extending to the inside of the conveying cover 1 is longer, when the slide bar 9 pushes the limit block 32 into the receiving groove 31, one end of the bending plate 19 can still extend to the top of the pressure plate 45, pressing the pressure plate 45 downward, and assisting the negative pressure adsorption force generated by the vacuum generator 2 to adsorb the damping plate 42 downward.

[0044] For example, in one embodiment, the present invention further provides a method for producing a high-efficiency radiative cooling film, which is applied to the above-mentioned high-efficiency radiative cooling film production device, comprising the following steps:

[0045] Step S1: The radiant cooling film to be transported is placed inside the transport cover 1, and the radiant cooling film is pressed against the inside of the flat recess 26 by the cleaning roller 16. When the radiant cooling film is transported, the driving component can drive the cleaning roller 16 to clean it, and at the same time drive the consignment component to reciprocate, thereby intermittently transporting the radiant cooling film to one side at equal distances. Before transporting, the feedback control component is also triggered to cause the consignment component to adsorb and fix the radiant cooling film, making the transport more stable.

[0046] Step S2: When the driving component is working, the swing arm 6 rotates to drive the slider 8 to slide back and forth up and down inside the waist-shaped frame 7, thereby driving the waist-shaped frame 7 to slide back and forth horizontally, so that it drives the slider 9 to slide back and forth inside the slide 3. When the slider 9 slides to one side of the slide 3, it triggers the feedback control component to work. When it slides to the other side of the slide 3, it releases the adsorption of the consignment component on the radiant cooling film. At the same time, when the slider 9 slides, it drives the driven gear 12 to rotate through the rack 10, thereby driving the cleaning roller 16 to clean the transported radiant cooling film.

[0047] Step S3: When the shipping assembly is working, the radiant cooling film is attached to the flat recess 26 on the top of the support plate 17. When the slide bar 9 slides to one side of the slideway 3, the feedback control assembly is triggered. Under the action of the negative pressure adsorption force generated by the vacuum generator 2, the air inside the air cavity 20 can be sucked into the through hole 39 through the bent flow channel 13, and then enter the buffer cavity 35 through the through hole 39, and finally enter the vacuum generator 2 through the filter port 37 and the air intake channel 15. At this time, the interior of the air cavity 20 is in a vacuum adsorption state, and the bottom of the radiant cooling film can be adsorbed and fixed;

[0048] Step S4: When the feedback control component is working, when the limit block 32 is pushed into the receiving groove 31, the cylindrical block 28 will be pushed into the cylindrical cavity 27 through the connecting rod 30. During the pushing process, the bending plate 19 will be driven to slide toward the side of the cylindrical cavity 27. Since the end of the bending plate 19 extending to the inside of the conveying cover 1 is longer, when the slide bar 9 pushes the limit block 32 into the receiving groove 31, one end of the bending plate 19 can still extend to the top of the pressure plate 45, pressing the pressure plate 45 downward, and the negative pressure adsorption force generated by the auxiliary vacuum generator 2 will adsorb the damping plate 42 downward.

10. A method for producing a high-efficiency radiative cooling film, applied to a production device for a high-efficiency radiative cooling film according to any one of claims 1 to 9, characterized in that: The following steps are involved: Step S1: placing the radiation cooling film to be transported inside the transport cover (1), and pressing the radiation cooling film into the inside of the flat recess (26) through the cleaning roller (16). When the radiation cooling film is transported, the driving component can drive the cleaning roller (16) to clean it, and at the same time drive the consignment component to reciprocate, thereby intermittently transporting the radiation cooling film to one side at equal distances. Before transporting, the feedback control component is also triggered to cause the consignment component to adsorb and fix the radiation cooling film, making the transport more stable. Step S2: When the driving component is working, the swing rod (6) rotates to drive the slider (8) to slide back and forth up and down inside the waist-shaped frame (7), thereby driving the waist-shaped frame (7) to slide back and forth horizontally, so that it drives the slide bar (9) to slide back and forth inside the slideway (3). When the slide bar (9) slides to one side of the slideway (3), it triggers the feedback control component to work. When it slides to the other side of the slideway (3), it releases the adsorption of the consignment component on the radiation cooling film. At the same time, when the slide bar (9) slides, it drives the driven gear (12) to rotate through the rack (10), thereby driving the cleaning roller (16) to clean the transported radiation cooling film. Step S3: When the consignment assembly is working, the radiation cooling film is attached to the inside of the flat recess (26) on the top of the support plate (17). When the slide bar (9) slides to one side of the slideway (3), the feedback control assembly is triggered. Under the action of the negative pressure adsorption force generated by the vacuum generator (2), the air inside the air cavity (20) can be sucked into the inside of the through hole (39) through the bent flow channel (13), and then enter the buffer cavity (35) through the through hole (39), and finally enter the inside of the vacuum generator (2) through the filter port (37) and the air intake channel (15). At this time, the inside of the air cavity (20) is in a vacuum adsorption state, and the bottom of the radiation cooling film can be adsorbed and fixed; Step S4: When the feedback control component is working, when the limit block (32) is pushed into the receiving groove (31), the cylindrical block (28) is pushed into the cylindrical cavity (27) through the connecting rod (30). During the pushing process, the bending plate (19) is driven to slide toward one side of the cylindrical cavity (27). Since the end of the bending plate (19) extending to the inside of the conveying cover (1) is longer, when the slide bar (9) pushes the limit block (32) into the receiving groove (31), one end of the bending plate (19) can still extend to the top of the pressing plate (45), pressing the pressing plate (45) downward, and the negative pressure adsorption force generated by the auxiliary vacuum generator (2) adsorbs the damping plate (42) downward.
