Description

Technical Field

[0001] The invention relates to the technical field of vacuum insulation panels, and in particular to a manufacturing process of a vacuum insulation panel with regular sides. Background Art

[0002] Vacuum insulation panel (VIP panel) is the abbreviation of Vacuum Insulation Panel in English. It has the characteristics of environmental protection and high energy saving. Therefore, vacuum insulation panel is widely used in home appliances (for example: refrigerators, freezers, water heaters, insulated boxes, etc.), cold chain logistics (for example: cold storage, refrigerated boxes, insulated vehicles, insulated containers, etc.) and construction (for example: external wall insulation, internal wall insulation, air ducts, etc.) and special fields such as aerospace.

[0003] The vacuum insulation panel usually includes a barrier film bag, a core material and an adsorbent. The core material and the adsorbent are arranged in the barrier film bag, and the vacuum insulation panel is formed by vacuumizing and heat-sealing the bag opening of the barrier film bag. The core materials of the vacuum insulation panel are varied. Some core materials include air-permeable and impermeable powder bags and powdered materials. When preparing this kind of core material, the powdered material is first placed in the air-permeable and impermeable powder bag, and then the air-permeable and impermeable powder bag is sealed, and finally it is placed in a press and pressed from top to bottom to form a plate-shaped core material. The core material is placed in a barrier film bag and vacuumized and heat-sealed to form a vacuum insulation panel.

[0004] However, the sides of the vacuum insulation panels made by this method are often uneven, because when the core material is pressed into a plate-shaped core material under the action of a press, only the upper and lower surfaces of the core material can be guaranteed to be flat, but the sides of the core material cannot be guaranteed to be flat. As a result, after the core material is bagged and evacuated to form a vacuum insulation panel, the sides of the vacuum insulation panel are uneven, affecting the use of the vacuum insulation panel. Summary of the invention

DETAILED DESCRIPTION

[0043] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0044] like Figures 1 to 10 As shown, a manufacturing process of a vacuum insulation panel with regular side parts of the present invention comprises the following steps:

[0045] Step 1: make an air-permeable and impermeable powder bag 1 according to the specifications of the vacuum insulation panel, and the air-permeable and impermeable powder bag 1 has an opening; step 2: fill the powdery material 2 into the air-permeable and impermeable powder bag 1 through the opening, and then seal the opening; step 3: place the air-permeable and impermeable powder bag 1 filled with the powdery material 2 in the press 3, and vibrate the powdery material 2 in the air-permeable and impermeable powder bag 1; step 4: the flattening mechanism 32 flattens the upper surface of the air-permeable and impermeable powder bag 1; at the same time, the side pressing mechanism 33 flattens the side of the air-permeable and impermeable powder bag 1, so that the upper and lower surfaces and the side surfaces of the air-permeable and impermeable powder bag 1 are flat, forming a regular core material 4; step 5: move the core material 4 into the barrier film bag 5 through the bag opening of the barrier film bag 5; step 6: place the barrier film bag 5 with the core material 4 in a vacuum device for vacuuming, and then heat-seal the bag opening of the barrier film bag 5 to form a vacuum insulation panel.

[0046] Thus, the present invention relates to a manufacturing process for a vacuum insulation panel with regular sides. During the manufacturing process, after the air-permeable and powder-impermeable bag 1 filled with powdery material 2 is placed in a press 3 for vibration, a flattening mechanism 32 flattens the upper surface of the air-permeable and powder-impermeable bag 1. When the upper surface is flattened, a side pressing mechanism 33 flattens the side of the air-permeable and powder-impermeable bag 1, thereby making the upper and lower surfaces and the side surfaces of the core material 4 formed by pressing the press 3 flat, and making a regular core material 4. After the core material 4 is placed in a barrier film bag 5, the side of the vacuum insulation panel formed by vacuuming and heat sealing is regular.

[0047] Optionally, the air-permeable and powder-impermeable bag 1 is made of non-woven fabric, glass fiber cloth or carbon fiber cloth, and the powdery material 2 is one or more of fumed silica, precipitated silica, expanded perlite, microsilica powder, fly ash, hollow glass microspheres and expanded vermiculite.

[0048] After the powdery material 2 is placed in the air-permeable and impermeable powder bag 1, during the vacuuming process, the gas in the powdery material 2 will be extracted from the fine holes formed on the air-permeable and impermeable powder bag 1, while the powdery material 2 will not pass through the air-permeable and impermeable powder bag 1, thereby achieving vacuuming of the core material 4.

[0049] In this embodiment, the press 3 includes a frame 31, a flattening mechanism 32 and a side pressing mechanism 33. The flattening mechanism 32 is arranged on the frame 31, and the side pressing mechanism 33 is arranged on the frame 31. By arranging the flattening mechanism 32 and the side pressing mechanism 33, the upper surface and the side of the air-permeable and impermeable powder bag 1 are flattened respectively, so that the whole is regular.

[0050] Furthermore, the press 3 also includes a vibration mechanism 34, which is connected to the flattening mechanism 32 and driven to rise and fall by the flattening mechanism 32. The vibration mechanism 34 vibrates the air-permeable powder-proof bag 1 to make the powdery material 2 evenly distributed in the air-permeable powder-proof bag 1. The traditional method is to manually smooth the powdery material 2, which has the disadvantage that manual smoothing is uneven. In view of this problem, in this embodiment, a vibration mechanism 34 is provided. When the air-permeable powder-proof bag 1 is placed on the vibration mechanism 34, the powdery material 2 in the air-permeable powder-proof bag 1 is automatically vibrated and compacted, so that the powdery material 2 is evenly distributed in the air-permeable powder-proof bag 1. In this way, the density of different parts of the core material 4 after pressing is basically consistent.

[0051] In some examples, the vibration mechanism 34 includes a vibration table 341, a vibration motor 342 and a vibration frame 343. The vibration motor 342 is connected to the vibration table 341 and drives the vibration table 341 to vibrate. The vibration frame 343 can be raised and lowered on the vibration table 341, and a limiting groove is formed in the vibration frame 343. After the air-permeable powder-impermeable bag 1 is placed on the vibration table 341, the vibration motor 342 drives the vibration table 341 to vibrate, and the vibration of the vibration table 341 realizes the vibration of the air-permeable powder-impermeable bag 1, thereby realizing the vibration and compaction of the powdered material 2 in the air-permeable powder-impermeable bag 1. By setting the vibration frame 343 and forming the limiting groove in the vibration frame 343, after the air-permeable powder bag 1 is placed in the limiting groove, the limiting groove limits the air-permeable powder bag 1 to prevent the air-permeable powder bag 1 from vibrating deviating during vibration. Since the vibration frame 343 can be raised and lowered on the vibration table 341 , after the vibration is completed, the vibration frame 343 descends, thereby facilitating the side pressure mechanism 33 to perform side pressure on the air-permeable and powder-impermeable bag 1 .

[0052] Specifically, the flattening mechanism 32 includes a lifting cylinder 321 and a flattening plate 322. The lifting cylinder 321 is arranged on the frame 31. The lifting cylinder 321 is connected to the vibration mechanism 34 and drives the vibration mechanism 34 to rise and fall. The flattening plate 322 is fixed on the frame 31, and the flattening plate 322 is located directly above the vibration table 341. The frame 31 includes an upper frame, a lower frame and a guide column 35. One end of the guide column 35 is connected to the upper frame, and the other end of the guide column 35 is connected to the lower frame. The flattening plate 322 is arranged on the upper frame, and the lifting cylinder 321 is arranged on the lower frame. The vibration mechanism 34 can be lifted and lowered along the guide column 321 through the mounting frame 36. Under the drive of the lifting cylinder 321, the vibration table 341 rises, thereby driving the upper surface of the air-permeable powder-impermeable bag 1 on the vibration table 341 to fit with the flattening plate 322, so as to flatten the upper surface of the air-permeable powder-impermeable bag 1.

[0053] In this embodiment, the side pressure mechanism 33 includes a side pressure cylinder 331 and a side pressure plate 332. The side pressure cylinder 331 is arranged on the frame 31, and the side pressure plate 332 is connected to the side pressure cylinder 331 and is driven by the side pressure cylinder 331 to move horizontally. Under the action of the side pressure cylinder 331, the side pressure plate 332 moves toward the side of the air-permeable powder-impermeable bag 1, so that the side pressure plate 332 is pressed on the side of the air-permeable powder-impermeable bag 1, thereby flattening the side of the air-permeable powder-impermeable bag 1.

[0054] Further, the side pressure mechanism 33 includes a left side pressure mechanism 33, a right side pressure mechanism 33, a front side pressure mechanism 33 and a rear side pressure mechanism 33, and the left side pressure mechanism 33, the right side pressure mechanism 33, the front side pressure mechanism 33 and the rear side pressure mechanism 33 all include a side pressure cylinder 331 and a side pressure plate 332; after the vibration table 341 rises, a side pressure space is formed between the pressure plate 322 and the vibration table 341, and the left side pressure mechanism 33 and the right side pressure mechanism 33 respectively perform side pressure on the left and right sides of the air-permeable and impermeable powder bag 1 through the side pressure space, and then, the left side pressure mechanism 33 and the right side pressure mechanism 33 are reset, and then, the front side pressure mechanism 33 and the rear side pressure mechanism 33 respectively perform side pressure on the front and rear sides of the air-permeable and impermeable powder bag 1 through the side pressure space, and finally, the front side pressure mechanism 33 and the rear side pressure mechanism 33 are reset.

[0055] The left and right sides of the air-permeable powder-impermeable bag 1 are flattened by setting the left side pressing mechanism 33 and the right side pressing mechanism 33, and the front and rear sides of the air-permeable powder-impermeable bag 1 are flattened by setting the front side pressing mechanism 33 and the rear side pressing mechanism 33, and finally the four sides of the air-permeable powder-impermeable bag 1 are flattened, so that the sides of the manufactured vacuum insulation panel are regular. After the left side pressing mechanism 33 and the right side pressing mechanism 33 press the air-permeable powder-impermeable bag 1, the left side pressing mechanism 33 and the right side pressing mechanism 33 are reset to achieve the role of giving way, so that the front side pressing mechanism 33 and the rear side pressing mechanism 33 can press the air-permeable powder-impermeable bag 1 sideways.

[0056] As a preferred embodiment, the side pressure plate 332 includes a side pressure mounting seat 3321, a side pressure base 3322, a side pressure elastic seat 3323 and a spring 3324. A mounting groove is formed in the side pressure mounting seat 3321. The side pressure base 3322 is arranged on the side pressure mounting seat 3321 and is located at the notch of the mounting groove. The side pressure mounting seat 3321 can be locked on the side pressure base 3322 by bolts. A mounting cavity is formed between the side pressure base 3322 and the side pressure mounting seat 3321. One end of the side pressure elastic seat 3323 is arranged in the mounting cavity, and the other end of the side pressure elastic seat 3323 protrudes from the side pressure mounting seat 3321. The spring 3324 is located in the mounting cavity, and one end of the spring 3324 is connected to the side pressure base 3322, and the other end of the spring 3324 is connected to the side pressure elastic seat 3323.

[0057] During installation, the spring 3324 is placed in the installation cavity so that one end of the spring 3324 abuts against the side pressure elastic seat 3323, and then the side pressure base 3322 is fixed on the side pressure installation seat 3321 so that the other end of the spring 3324 abuts against the side pressure base 3322, and the spring 3324 is in a compressed state. Under the action of the spring 3324, the side pressure elastic seat 3323 has a tendency to move away from the side pressure base 3322.

[0058] After the vibration table 341 rises, the vibration table 341 abuts against the side pressure elastic seat 3323 to compress the spring 3324, so that when vacuum insulation panels of different thicknesses are manufactured, the side pressure elastic seat 3323 can abut against the vibration table 341, thereby being suitable for flattening the sides of air-permeable and powder-impermeable bags 1 of different thicknesses, and having strong versatility.

[0059] Specifically, the side pressure mounting seat 3321 includes a first limit block 33211 and a second limit block 33212, and a through opening is formed between the first limit block 33211 and the second limit block 33212; the side pressure elastic seat 3323 includes a horizontal seat 33231 and a vertical seat 33232, the horizontal seat 33231 is arranged in the mounting cavity, one end of the horizontal seat 33231 can be abutted against the first limit block 33211, and the other end of the horizontal seat 33231 can be abutted against the second limit block 33212, one end of the vertical seat 33232 is fixed on the horizontal seat 33231, and the other end of the vertical seat 33232 passes through the through opening and protrudes from the side pressure mounting seat 3321.

[0060] By providing the first limiting block 33211 and the second limiting block 33212 , the horizontal seat 33231 is limited so that the side pressure elastic seat 3323 will not separate from the side pressure mounting seat 3321 .

[0061] In this embodiment, a step 3325 is formed between the side of the vertical seat 33232 and the side of the side pressure mounting seat 3321. Since the vibration table 341 rises under the action of the lifting cylinder 321, and the vertical seat 33232 is arranged toward the vibration table 341, after the side pressure mechanism 33 performs side pressure on the air-permeable powder-impermeable bag 1, a first layer 11 is formed at the lower part of the air-permeable powder-impermeable bag 1, and a second layer 12 is formed at the upper part of the air-permeable powder-impermeable bag 1. The width of the second layer 12 is smaller than the width of the first layer 11, so that the side of the air-permeable powder-impermeable bag 1 forms a structure with a small top and a large bottom, and the powder material in the air-permeable powder bag 1 is not easy to collapse. A groove 13 is formed on the outer side of the second layer 12. After the vacuum insulation panel is manufactured, when folding the edge, the edge leaf can be folded in the direction of the groove 13, and the depth of the groove 13 can be equal to the thickness of the edge leaf, so that the side of the vacuum insulation panel is flat after the vacuum insulation panel is folded.

[0062] Furthermore, in step five, the core material 4 can be transferred into the barrier film bag 5 by means of a pallet.

[0063] In a preferred embodiment of the present invention, before placing the core material 4 on the barrier film bag 5, the annular frame 6 is placed on the core material 4 so that the inner side of the annular frame 6 fits with the outer side of the core material 4 and a flat surface 61 is formed on the outer side of the annular frame 6. During production, after the inner side of the annular frame 6 fits with the outer side of the core material 4, the whole is placed in the barrier film bag 5. Since the flat surface 61 is formed on the outer side of the annular frame 6, after the vacuum insulation panel is manufactured, the inner side of the barrier film bag 5 fits with the outer side of the annular frame 6. The flat surface 61 formed on the outer side of the annular frame 6 makes the outer side of the barrier film bag 5 flat, thereby making the side of the manufactured vacuum insulation panel flat, which is convenient for the use of the vacuum insulation panel.

[0064] Further, the annular frame 6 is an annular polyurethane frame or an annular phenolic frame. The annular polyurethane frame has a certain hardness, so that the annular polyurethane frame is not easy to break during the process of making the vacuum insulation panel. At the same time, the annular polyurethane frame or the annular phenolic frame has a good thermal insulation effect, so that the thermal conductivity of the vacuum insulation panel is low. Among them, the opening rate of the annular phenolic frame is preferably above 95%.

[0065] In this embodiment, the flat surface 61 includes a first vertical surface 611, a transition connection surface 612 and a second vertical surface 613. The first vertical surface 611 is connected to the lower side of the transition connection surface 612, and the upper side of the transition connection surface 612 is connected to the second vertical surface 613. The transition connection surface 612 is an inclined surface.

[0066] By setting the first vertical surface 611, the transition connection surface 612 and the second vertical surface 613, a groove 62 is formed on the side of the annular frame 6. In this way, after the vacuum insulation panel is manufactured, when folding the edge, the edge leaf can be folded in the direction of the groove 62, and the depth of the groove 62 can be equal to the thickness of the edge leaf, so that the side of the vacuum insulation panel is flat after the edge is folded. The angles formed by the inclined surface and the first vertical surface 611 and the second vertical surface 613 are all obtuse angles, and the height of the first vertical surface 611 is equal to the height of the second vertical surface 613, so that the groove 62 formed on the side of the annular frame 6 opens outward, which is convenient for the edge leaf to be folded in the direction of the groove 62.

[0067] At the same time, by arranging the annular polyurethane frame or the annular phenolic frame outside the core material 4, the annular polyurethane frame or the annular phenolic frame plays a protective role, so that the overall structure of the core material 4 is not easily destroyed when it is transferred to the barrier film bag 5 through the pallet.

[0068] In this embodiment, the adsorbent 7 is disposed on the core material 4. By disposing the adsorbent 7, the gas remaining in the powdery core material 4 can be absorbed, the vacuum degree in the vacuum insulation panel is increased, and thus the thermal insulation effect of the vacuum insulation panel is improved.

[0069] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent transformations made using the contents of the present invention's specification and drawings, or directly or indirectly applied in related technical fields, are also included in the patent protection scope of the present invention.
