Description

Technical Field

[0001] The utility model relates to the technical field of wrinkle removal devices, in particular to a wrinkle removal device for a vacuum insulation panel. Background Art

[0002] Vacuum Insulation Panel (VIP) is a new type of high-efficiency thermal insulation material. Its core part is composed of a vacuum insulation layer, which has excellent thermal insulation and environmental performance. It uses a high degree of vacuum to isolate heat conduction, thereby achieving the purpose of heat preservation and energy saving. The thermal conductivity of VIP is very low, usually less than 4mW / (m·K) (20℃), which makes it produce no environmental pollution during its manufacturing, use and post-processing, so it is considered to be an environmentally friendly thermal insulation material.

[0003] In the production process of vacuum insulation panels, due to the unevenness of the core material, uneven force during vacuuming or thermal expansion and contraction of the material due to temperature changes, wrinkles will appear on the surface of the vacuum insulation panels. The wrinkles will destroy the uniformity of the panels, thus affecting their thermal insulation performance. The wrinkles will form local thermal bridges in the panels, reducing the overall thermal insulation effect. For the factory, since wrinkles will affect the overall appearance of the panels, many customers have requested replacements or even refused to accept them, adding a lot of trouble to the manufacturer.

[0004] After searching, it is found that there are few wrinkle removal devices in the field of vacuum insulation panels, and wrinkle removal in similar fields generally adopts the method of wrinkle removal rollers. The specific scheme lies in the special surface texture of the roller, which can help flatten the material when the material passes through to prevent the formation of wrinkles. At the same time, it is combined with some heating methods. It is obviously not suitable for the vacuum insulation panels of the present application. The specific reason is that after the vacuum insulation panel is produced, it has been hot-pressed into shape by the core board and the insulation film on both sides of the core board. It is no longer a single membrane sheet, but the wrinkles of the insulation film heat-sealed on the surface of the core board, and the direction of the wrinkles is disordered. The wrinkle removal roller can only remove wrinkles in a specific direction of the wrinkles of the film material, and cannot remove wrinkles of the insulation film wrinkled on the surface of the board.

[0005] Therefore, in order to solve the problem of wrinkles on the surface of vacuum insulation panels, which destroy the uniformity of the panels and also affect their thermal insulation performance, the applicant designed a solution to solve the wrinkles of the insulation film of vacuum insulation panels from the source based on the specific principle of wrinkles. Utility Model Content

[0006] The main purpose of the utility model is to provide a diaphragm to solve the technical problem of removing disorderly wrinkled plates on the surface.

[0007] In order to achieve the above-mentioned purpose, the utility model proposes a vacuum insulation panel wrinkle removal device, comprising a mounting frame placed in a vacuum environment, a vacuum insulation panel is placed on the mounting frame, and further comprising

[0008] The wrinkle-removing member is disposed on the mounting bracket and includes at least one wrinkle-removing plate facing the corrugated surface of the vacuum insulation panel. At least one of the wrinkle-removing plates can approach or move away from the vacuum insulation panel, and transmission elements are symmetrically arranged at both bidirectional ends of the wrinkle-removing plate; and

[0009] The lifting member is disposed on the mounting bracket and can drive the wrinkle-removing plate to approach or move away from the vacuum insulation panel;

[0010] Wherein, the transmission directions of the transmission elements all face the side of the vacuum insulation panel.

[0011] Further, the wrinkle-removing plate includes a top plate and a bottom plate disposed on both sides of the vacuum insulation panel. The top plate and the bottom plate both face the vacuum insulation panel, and the top plate can approach or move away from the vacuum insulation panel.

[0012] Further, the mounting bracket includes a frame body, and a plurality of wrinkle-removing layers are provided on the frame body along the moving direction of the top plate. Each wrinkle-removing layer is provided with a top plate and a bottom plate; wherein, the bottom plate is fixed to the inner wall of the wrinkle-removing layer, and the vacuum insulation panel is received thereon, and the top plate is slidably connected to the wrinkle-removing layer on the side of the vacuum insulation panel away from the bottom plate.

[0013] Further, the top plate includes a top plate body, a first wrinkle-removing area is opened at both ends in the length direction of the top plate body, and a second wrinkle-removing area is opened at both ends in the width direction of the top plate body. The transmission elements are installed on the inner walls of the first wrinkle-removing area and the second wrinkle-removing area.

[0014] Further, the bottom plate includes a bottom plate body, a third wrinkle-removing area and a fourth wrinkle-removing area corresponding to the first wrinkle-removing area and the second wrinkle-removing area are opened on the bottom plate body, and the transmission elements are installed on the inner walls of the third wrinkle-removing area and the fourth wrinkle-removing area.

[0015] Further, the transmission element includes a belt arranged parallel to the plate surface of the wrinkle-removing plate. The fitting surface of the belt faces the vacuum insulation panel, and the transmission direction faces the side of the vacuum insulation panel.

[0016] Further, the lifting member includes a driving device and a guide rod provided on the mounting bracket.

[0018] Further, both ends of the cross bar are fixed to the guide rod.

[0019] Further, a flange is provided on the outer part of the guide rod, and both ends of the cross bar are slidably connected to the guide rod.

DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the following specific embodiments are only used to explain the utility model and do not constitute a limitation on the utility model.

[0031] According to the manufacturer's communication and briefing, there is a supplementary description of the principle of the device, specifically:

[0032] When producing vacuum insulation panels with the prior art, wrinkles often appear on the surface of the product. The presence of these wrinkles affects the appearance and is difficult to remove in an atmospheric environment. The reason is that the air pressure inside the vacuum insulation panel is very low and is in a vacuum state. When it is packaged and taken out of the vacuum chamber, its surface will be subjected to a pressure of standard atmospheric pressure. Therefore, these wrinkles are actually fixed to the surface of the core material by a large force. At this time, it is very difficult to pull it apart by external force, and the barrier bag may be damaged. Therefore, it is difficult to remove the wrinkles formed by the heat-sealed insulation film on the surface of the vacuum insulation panel only by using a wrinkle removal roller. Therefore, the removal of wrinkles has always been a difficult problem in the vacuum packaging industry.

[0033] As mentioned above, the wrinkles on the VIP board surface are fixed by a standard atmospheric pressure in the atmospheric environment, and it is difficult to flatten them with external force. Therefore, it is thought that putting the finished VIP board with wrinkles back into the vacuum environment can effectively eliminate the pressure exerted by the atmospheric pressure on the board surface. At this time, the surface of the barrier bag is in a state of no force, and it can be flattened by applying a slight force, and this force is maintained until the vacuum environment is removed. At this time, the VIP board is taken out of the vacuum chamber, and the wrinkles on the board surface can be removed.

[0034] This paper designs a device that can flatten the wrinkles of the barrier bag on the surface of the VIP board after it enters the vacuum environment.

[0035] like Figure 1As shown in the figure, a device for removing wrinkles from a vacuum insulation panel includes a mounting frame 10, a wrinkle-removing member 20 provided on the mounting frame 10, and a lifting member 30 for driving the wrinkle-removing member 20 to approach the vacuum insulation panel 40. Among them, the wrinkle-removing member 20 can remove wrinkles from one side of the vacuum insulation panel 40, or can remove wrinkles from both sides of the vacuum insulation panel 40 simultaneously. For this application, to improve the wrinkle-removing effect, it is preferably to remove wrinkles from both sides simultaneously. The entire device is placed in a vacuum for use to facilitate wrinkle removal from the vacuum insulation panel 40.

[0036] Specifically, as Figure 1 shown in the figure, the mounting frame 10 includes a frame body 101, several wrinkle-removing layers 102 provided on the frame body 101, and backing plates 103 installed on the corresponding wrinkle-removing layers 102. The number of backing plates 103 is the same as that of the wrinkle-removing layers 102. The backing plates 103 are used to place the vacuum insulation panel 40. With the design of multiple wrinkle-removing layers 102, the vacuum insulation panel 40 can be placed in each wrinkle-removing layer 102, enabling multiple vacuum insulation panels 40 to be wrinkled simultaneously and improving the wrinkle-removing efficiency.

[0037] As Figure 1 and Figure 2 shown in the figure, the lifting member 30 includes driving devices 301 symmetrically installed on both sides of the frame body 101, and connecting members 302 installed at the output ends of the driving devices 301. One end of the connecting member 302 away from the driving device 301 is fixedly connected to a cross bar 303. Guide rods 304 are respectively fixedly installed at both ends of the cross bar 303. The guide rods 304 slide vertically with the frame body 101, and the guide rods 304 are used to drive the wrinkle-removing member 20 to lift and lower. The two ends of the cross bar 303 can also slide with the guide rods 304. When the guide rods 304 rise, the two ends of the cross bar 303 only need to lean against the flanges fixed outside the guide rods 304 to lift the guide rods 304.

[0038] Among them, the driving device 301 is rotatably connected to the frame body 101. The driving device 301 can adopt a lifting motor, a cylinder, an oil cylinder, and an electric cylinder, which are prior art in this equipment. The connecting member 302 can be connected in the form of a rod, a block, or a wire, and it only needs to connect the output end of the driving device 301 and the cross bar 303. Preferably, it is connected by a chain, and its specific effect will be mentioned later.

[0039] As Figures 1-4 shown in the figure, for the design of the wrinkle-removing member 20, as Embodiment 1 of this application:

[0040] Example 1 uses single-sided wrinkle removal. Specifically, the wrinkle-removing member 20 includes a top plate 201 disposed inside the wrinkle-removing layer 102. Both ends of the top plate 201 are connected with mounting bars 203 and are fixed to the guide rods 304 through the mounting bars 203. The guide rods 304 move vertically, which can drive the top plate 201 to approach or move away from the vacuum insulation panel 40 on the backing plate 103. After the top plate 201 approaches the vacuum insulation panel 40, the surface of the vacuum insulation panel 40 can be wrinkled in a vacuum environment. After one side of the vacuum insulation panel 40 is wrinkled, the vacuum insulation panel 40 is turned over and wrinkled again, so that both sides of the vacuum insulation panel 40 can be wrinkled. The wrinkle removal uses a transmission element, and the specific wrinkle removal method of the transmission element is as follows:

[0041] The top plate 201 includes a top plate body 2010, and a first wrinkle-removing area 2011 and a second wrinkle-removing area 2012 symmetrically arranged along the length direction and the width direction of the top plate body 2010 respectively, specifically as Figure 3 shown. Driving rollers 50 are installed on the inner walls of the first wrinkle-removing area 2011 and the second wrinkle-removing area 2012. A belt 60 is sleeved outside the driving rollers 50, specifically as Figure 4 shown. The belt 60 can be driven by the rotation of the driving rollers 50 in the first wrinkle-removing area 2011 and the second wrinkle-removing area 2012. The side of the belt 60 facing the vacuum insulation panel 40 is transmitted towards the edge of the vacuum insulation panel 40. There is friction between the belt 60 and the surface of the vacuum insulation panel 40. In a vacuum environment, the belts 60 installed in the two first wrinkle-removing areas 2011 and the second wrinkle-removing areas 2012 are simultaneously transmitted in the vertical direction towards the edge of the vacuum insulation panel 40, and drive the wrinkled part of the vacuum insulation panel 40 towards the edge through their own friction until the redundant wrinkled part is driven to the edge of the vacuum insulation panel 40. At the same time, the wrinkles in different directions on the vacuum insulation panel 40 can be flattened. The wrinkled part is evenly unfolded to the side, and wrinkle removal can be achieved. The above belt 60 can be driven by the driving roller 50, and specifically, a motor can be used for driving. This solution is similar to a conveyor belt and is a prior art.

[0042] In addition, the transmission element can also use the driving roller 50. Grooves or coating materials are used on the surface of the driving roller 50, so that there is friction between the driving roller 50 and the wrinkled surface of the vacuum insulation panel 40, and the vacuum insulation panel 40 can be wrinkled only by the rotation of the driving roller 50.

[0043] As Example 2 of the present application:

[0044] As Figures 2-4As shown, based on the first embodiment of the present application, the wrinkle-removing member 20 further includes a bottom plate 202 installed on the backing plate 103. The bottom plate 202 includes a top plate body 2010. A wrinkle-removing area three 2021 and a wrinkle-removing area four 2022 corresponding to the wrinkle-removing area one 2011 and the wrinkle-removing area two 2012 of the top plate body 2010 are provided on the top plate body 2010. The vacuum insulation panel 40 is placed between the bottom plate body 2020 and the top plate body 2010. Transmission elements are provided in the wrinkle-removing area one 2011, the wrinkle-removing area two 2012, the wrinkle-removing area three 2021, and the wrinkle-removing area four 2022, as can be known from the first embodiment. In the initial state, the vacuum insulation panel 40 is placed on the bottom plate body 2020 and is located in the wrinkle-removing area three 2021 and the wrinkle-removing area four 2022. The driving device 301 drives the guide rod 304 to move vertically through the connecting member 302 and the cross bar 303, which drives the top plate body 2010 to move downward and fit with the top end surface of the vacuum insulation panel 40. In a vacuum environment, the belts 60 in the wrinkle-removing areas of the top plate body 2010 and the bottom plate body 2020 are all transmitted toward the edge direction of the vacuum insulation panel 40, and the wrinkled parts of the vacuum insulation panel 40 are squeezed to the edge through friction, and after removing the wrinkles on the end surface of the vacuum insulation panel 40 and moving out of the vacuum environment, the wrinkle-removing operation can be completed.

[0045] As Figure 2 As shown, in the above operation, the top plate body 2010 only needs to lean on the vacuum insulation panel 40 by its own weight, and no additional pressure needs to be applied. Therefore, the connecting member 302 is preferably a chain. The driving device 301 drives the guide rod 304 to move upward through the chain and the cross bar 303, and the guide rod 304 drives the top plate 201 to move upward. At this time, the vacuum insulation panel 40 can be placed or taken out; when the driving device 301 drives the guide rod 304 to move downward through the chain and the cross bar 303 until the top plate body 2010 is attached to the wrinkled surface of the vacuum insulation panel 40, no pressure needs to be applied. Therefore, if there is an error in the driving device 301 and it continues to move downward, the chain will gradually turn and bend, so that after the driving device 301 moves downward, the top plate body 2010 still leans on the vacuum insulation panel 40, avoiding applying additional downward pressure on the vacuum insulation panel 40.

[0046] It should be noted that when the vacuum insulation panel 40 is placed on the wrinkle removal areas three 2021 and four 2022 of the bottom plate body 2020, and the four sides of the vacuum insulation panel 40 are slightly recessed on the belt 60. To ensure that the four sides of the vacuum insulation panel 40 can be recessed into the belt 60, the drive roller 50 along the reverse transmission direction of the belt 60 is lower than the drive roller 50 along the transmission direction of the belt 60 to compensate for the recessed part at the edge of the vacuum insulation panel 40; when the wrinkle removal areas one 2011 and two 2012 of the top plate body 2010 are attached to the top wrinkled surface of the vacuum insulation panel 40, when the drive roller 50 drives the belt 60 to remove wrinkles from the plate surface of the vacuum insulation panel 40, since the frequency adjustment of the motors used by the drive rollers 50 in each wrinkle removal area is the same, the vacuum insulation panel 40 is kept recessed in the belt 60, and it can be limited while removing wrinkles, avoiding deviation during wrinkle removal due to different contact surfaces of the vacuum insulation panel 40 in different areas.

[0047] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structural transformation made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or direct / indirect application in other related technical fields is included in the patent protection scope of the present invention.
