Description

Technical Field

[0001] The utility model relates to the technical field of board surface dust removal, in particular to a vacuum insulation board dust removal device. Background Art

[0002] Vacuum Insulation Panel (VIP) is a new type of high-efficiency insulation material. Its core feature is to isolate heat conduction through high vacuum degree, thereby achieving the purpose of heat preservation and energy saving.

[0003] During the production of vacuum insulation panels, dust is very likely to accumulate on the surface of the vacuum insulation panels in an indoor production environment. The accumulation of dust will affect the thermal insulation performance of the vacuum insulation panels because the dust will clog the micropores on the surface of the panels, affecting their thermal insulation effect. In addition, the long-term accumulation of dust will also accelerate the corrosion of the material on the surface of the vacuum insulation panels and affect their service life.

[0004] As major manufacturers consider, in order to solve the dust problem on the surface of vacuum insulation panels, fans are used to remove dust from the surface of vacuum insulation panels. Wind force is used to directly remove dust from the surface of vacuum insulation panels. Specifically, dust hoods are set to move the vacuum insulation panels to the dust hoods. The dust hoods use fans to centrally clean the dust on the surface of vacuum insulation panels to ensure that the surface of the vacuum insulation panels is clean and tidy.

[0005] The existing vacuum insulation panels are moved into the dust removal hood, and wind is used to treat the dust on the surface of the vacuum insulation panels in the dust removal hood. The internal space of the dust removal hood is large. As the wind is pulled, there are dead corners inside the dust removal hood. Since the air flow rate in this part is slow, the wind force in the part of the vacuum insulation panel far away from the wind source is weak, resulting in incomplete dust cleaning on the surface of the vacuum insulation panel and loose coating. Specifically, a rubber and plastic foam insulation board processing table blowing cleaning device is proposed in Chinese patent publication No. CN215314113U, which adopts a combination of a brush, air blowing and dust suction to achieve dust removal on the surface of the insulation board. The dust suction position is fixed and the negative pressure adsorption force is limited, so that the floating dust can easily fall onto the insulation board at different positions of the hood.

[0006] Therefore, the present application aims to improve the dust removal effect on the surface of the vacuum insulation panel, reduce the dead angle of the vacuum insulation panel in the vacuum cover, and improve the adhesion of the film of the vacuum insulation panel. Utility Model Content

[0007] The main purpose of the utility model is to provide a vacuum insulation panel dust removal device, aiming to improve the dust removal effect on the surface of the vacuum insulation panel, reduce the dead angle of the vacuum insulation panel in the vacuum cover, and improve the adhesion of the vacuum insulation panel film.

[0008] In order to achieve the above object, the utility model proposes a vacuum insulation panel dust removal device, comprising:

[0009] a conveyor that conveys the vacuum insulation panel; and

[0010] A dust removal member, arranged on the conveying member, comprising at least one dust removal cover, a dust removal roller rotatably arranged on the inner wall of the dust removal cover, and a guide device arranged inside the dust removal cover;

[0011] Among them, when the vacuum insulation panel is transmitted to the dust removal hood, the dust removal roller adheres to and absorbs the dust on the surface of the vacuum insulation panel, and the dust removal hood is also provided with a negative pressure port on the side away from the conveying member to extract dust from the dust removal hood, and the guide device is located between the dust removal roller and the negative pressure port.

[0012] Furthermore, the guide device includes a first guide plate installed on the inner wall of the dust removal cover, and the first guide plate is arranged on a side of the dust removal roller close to the negative pressure port.

[0013] Furthermore, a dust scraping mechanism is provided at one end of the first guide plate facing the dust removal roller, and the dust scraping mechanism is in contact with the outer wall of the dust removal roller.

[0014] Furthermore, a dust storage trough is provided at one end of the first guide plate close to the dust removal roller.

[0015] Furthermore, the guide device includes a second guide plate installed on the inner wall of the dust removal cover, and the second guide plate is arranged on both sides of the same plane where the dust removal roller and the negative pressure port are located.

[0016] Furthermore, a bent plate is further provided on the second guide plate, and when the negative pressure port absorbs dust, the bent plate tilts toward the negative pressure port.

[0017] Furthermore, the dust removal member also includes an adjustment device provided on the conveying member and a static elimination device installed on the adjustment device, and the dust removal cover is installed on the adjustment device.

[0018] Furthermore, the adjusting device includes an adjusting frame, a lifting mechanism arranged on the adjusting frame, and a connecting plate fixed to a lifting end of the lifting mechanism, and the connecting plate is connected to the dust cover and the static elimination device.

[0019] Furthermore, a gluing member and a cutting member are provided in the forward direction of the conveying member, the gluing member is used to apply film to the surface of the vacuum insulation panel, and the cutting member is used to cut off excess film material on the surface of the vacuum insulation panel.

[0020] Furthermore, the cutting piece includes a bracket arranged on the conveying piece, a moving device installed on the bracket, a cutter is arranged on the moving device, and a negative pressure device is also arranged on the bracket to absorb the cut free end of the film.

[0021] The above technical solution has the following advantages:

[0022] The utility model adopts a dust removal component to remove dust from the vacuum insulation board of the conveying component. The dust removal component comprises a dust removal hood, a dust removal roller and a guide device. The dust removal roller fits the surface of the vacuum insulation board passing through the dust removal hood so that the dust on the surface of the vacuum insulation board is adsorbed on the dust removal roller. After the dust removal roller rotates, the dust on the surface of the dust removal roller is transmitted to the negative pressure port, so that the negative pressure port drives the dust on the surface of the dust removal roller to be extracted. The guide device reduces the area in the dust removal hood, increases the air flow rate in the dust removal hood, and improves the dust removal effect of the dust. Combined with the dust removal roller, the surface of the vacuum insulation board is adhered to and adsorbed without dead angles, so that the vacuum insulation board is avoided to be adsorbed only by the dust removal hood, resulting in the problem of cleaning dead angles at the edge of the dust removal hood, and the adhesion of the film of the vacuum insulation board is improved.

DETAILED DESCRIPTION

[0032] 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.

[0033] like Figure 1 , Figure 2 and Figure 5 As shown, a vacuum insulation panel dust removal device includes a conveying member 1 and a dust removal member 2, wherein the conveying member 1 conveys the vacuum insulation panel 7; the dust removal member 2 is arranged on the conveying member 1, and includes at least one dust removal cover 21, a dust removal roller 24 rotatably arranged on the inner wall of the dust removal cover 21, and a guide device 25 arranged inside the dust removal cover 21; wherein, when the vacuum insulation panel 7 is transmitted to the dust removal cover 21, the dust removal roller 24 adheres to and absorbs the dust on the surface of the vacuum insulation panel 7, and a negative pressure port is also provided on the side of the dust removal cover 21 away from the conveying member to extract dust from the dust removal cover 21, and the guide device 25 is located between the dust removal roller 24 and the negative pressure port. The conveyor 1 conveys the vacuum insulation panel 7 to ensure the automatic production of the vacuum insulation panel 7 on the conveyor line. The conveyor 1 can be conveyed by a belt, a conveyor roller or a guide wheel. A gap is provided on the side of the dust cover 21 facing the conveyor 1. When the vacuum insulation panel 7 moves into the dust cover 21 from the gap between the dust cover 21 and the conveyor 1, the dust roller 24 in the dust cover 21 rolls and adsorbs the surface of the vacuum insulation panel 7, so that the dust on the surface of the vacuum insulation panel 7 adheres to the dust roller 24. As the dust roller 24 rotates, the dust is removed. The dust on the surface of the roller 24 rotates to the negative pressure port, and the dust on the surface of the dust removal roller 24 is discharged along with the adsorption of the negative pressure port. At the same time, the guide device 25 also guides the dust flowing toward the negative pressure port. At the same time, the addition of the guide device 25 also reduces the area inside the dust removal hood 21, thereby increasing the air flow rate in the dust removal hood 21 and improving the dust removal effect. At the same time, the dust removal roller 24 adheres to the surface of the vacuum insulation panel 7 without dead angles to absorb dust, thereby avoiding the problem of cleaning dead angles at the edge of the dust removal hood 21 due to the vacuum insulation panel 7 only being adsorbed by the dust removal hood 21.

[0034] Specifically, the dust hood 21 can be in the form of a rectangular parallelepiped, or the two ends of the rectangular parallelepiped can be beveled to reduce the space inside the dust hood 21 and increase wind force. A cube can also be used to increase the area of ​​the vacuum insulation panel 7 that remains inside the dust hood 21. The negative pressure port at the top of the dust hood 21 can be connected to the adsorption pipe of the fan to provide wind force for the dust hood 21. One or more groups of dust hoods 21 can be set on the conveying member 1. In order to improve the cleaning effect, the present application preferably sets two groups of dust hoods 21.

[0035] like Figure 1 and Figure 2As shown, the guide device 25 includes a first guide plate 251 installed on the inner wall of the dust removal hood 21, and the first guide plate 251 is arranged on the side of the dust removal roller 24 close to the negative pressure port, wherein when the dust removal roller 24 rotates, it drives the dust adsorbed on its surface to rotate until the dust rotates to the first guide plate 251. Under the adsorption condition of the negative pressure port, the surface of the dust removal roller 24 flows toward the negative pressure port with the air flow, and the dust contacts the guide device 25 during the flow, so that the dust flows toward the negative pressure port along a specific path, thereby preventing the dust from forming a cyclone in the dust removal hood 21 and causing dust accumulation.

[0036] like Figure 2 and Figure 4 As shown, in order to further improve the dust removal effect of the first guide plate 251, a dust scraping mechanism 254 is provided at one end of the first guide plate 251 facing the dust roller 24, and the dust scraping mechanism 254 is in contact with the outer wall of the dust roller 24, wherein the dust scraping mechanism 254 can be a brush, a scraper or a plastic strip, etc. The dust roller 24 is in contact with the vacuum insulation panel 7. With the transmission of the vacuum insulation panel 7, the dust roller 24 is driven to rotate by itself, and the dust roller 24 is in contact with the brush, the scraper or the plastic strip, so that the dust on the surface of the dust roller 24 is dissipated into the dust cover 21. At this time, the dust has been scattered from the vicinity of the negative pressure port, which greatly improves the dust adsorption force; the brush, the scraper or the plastic strip can also clean the stubborn dust on the surface of the dust roller 24 to avoid affecting the dust suction effect of the dust roller 24 on the vacuum insulation panel 7.

[0037] like Figure 2 and Figure 4 As shown, when the negative pressure port stops adsorption, the dust in the dust removal cover 21 will gradually scatter. In order to reduce the dust from scattering onto the dust removal roller 24 so as not to affect the subsequent dust removal effect, an ash storage groove 253 is provided at one end of the first guide plate 251 close to the dust removal roller 24. The ash storage groove can be integrally formed with the first guide plate 251, or can be welded to the bottom end of the first guide groove. The ash storage groove is hook-shaped, which can be a groove, an extended square groove or a straight groove. When the negative pressure port completes adsorption, the dust at the negative pressure port scatters in the dust removal cover 21 until the dust is scattered into the ash storage groove. This reduces the dust from scattering onto the dust removal roller 24, so as to prevent the dust removal effect of the first vacuum insulation panel 7 from being affected; the dust removal groove can also be set to a V-shape, that is, the part of the dust removal groove close to the negative pressure port is at the lowest end, and the two ends away from the negative pressure port are at the highest end, so that the dust can flow to the negative pressure port under the action of the inclined surface and negative pressure, thereby improving the dust adsorption efficiency; because the first guide plate 251 is close to the negative pressure port, a groove 252 is provided on the side of the first guide plate 251 facing the negative pressure port, thereby increasing the space for dust to flow from the groove 252 to the negative pressure port.

[0038] like Figure 2 and Figure 4As shown, the guide device 25 includes a second guide plate 255 installed on the inner wall of the dust removal cover 21, and the second guide plate 255 is arranged on both sides of the same plane where the dust removal roller 24 and the negative pressure port are located, wherein the second guide plate 255 and the first guide plate 251 can be arranged separately or together, preferably arranged together in the dust removal cover 21, when the second guide plate 255 is arranged in the dust removal cover 21, the second guide plate 255 is evenly arranged on both sides of the first guide plate 251, and the second guide plate 255 can also be the same as the first guide plate 251, and also be provided with the same dust removal groove, but no need to be provided A dust scraping mechanism 254 is provided. Since the second guide plate 255 is not located above the dust removal roller 24, a bent plate 256 is provided on the second guide plate 255. The bent plate 256 can be made of a flexible material, such as PVC, fiber material or carbon fiber material. When the negative pressure port absorbs dust, the bent plate 256 of the second guide plate 255 tilts toward the negative pressure port, leaving a gap between the bent plate 256 and the second guide plate 255. Dust can pass through the gap to prevent the dust from being blocked by the second guide plate 255, so as not to increase the circumferential distance of the dust and affect the discharge of the dust.

[0039] like Figure 1 , Figure 2 and Figure 5 As shown, the dust removal member 2 also includes an adjusting device 23 arranged on the conveying member 1 and an electrostatic eliminator 22 installed on the adjusting device 23. The dust cover 21 is installed on the adjusting device 23. The adjusting device 23 can be fixed on the conveying member 1, or it can be fixed after sliding and adjusting on the conveying member 1. The electrostatic eliminator 22 can adopt an electrostatic eliminator, an ion rod, an ion air gun, etc. When the present application adopts two groups of dust covers 21, the electrostatic eliminator 22 is arranged between the two groups of dust covers 21.

[0040] like Figure 2 and Figure 3As shown, the adjusting device 23 includes an adjusting frame 231, a lifting mechanism 233 arranged on the adjusting frame 231, and a connecting plate 234 fixed to the lifting end of the lifting mechanism 233, wherein the connecting plate 234 is connected to the dust cover 21 and the static elimination device 22, wherein the adjusting frame 231 slides on the conveying member 1 to adjust the position of the dust removing member 2, the adjusting frame 231 can be fixed by bolts, and the adjusting frame 231 can also be moved by sliding, and it is only necessary to ensure that it can be adjusted by sliding on the conveying member 1, and the lifting mechanism can be lifted and lowered on the adjusting frame 231 to adjust the height of the connecting plate 234, and the height adjustment of the connecting plate 234 can be The height of the dust cover 21 and the static elimination device 22 is adjusted to meet the requirements of vacuum insulation panels 7 of different thicknesses and improve the scope of application. The lifting mechanism 233 can be adjusted by rotating the screw, that is, the rotation of the screw drives the slide to rise and fall, and the slide and the adjustment frame 231 slide vertically, while the slide and the connecting plate 234 are fixed to achieve adjustment of different heights. In order to further ensure its stability, a locking mechanism 232 is also provided on one side of the adjustment frame 231. For example, the slide is pressed against the adjustment frame 231 by bolts to ensure the stability of the connecting plate 234. In addition, the slide and the adjustment frame 231 can also be fixed by latches.

[0041] like Figure 1 and Figure 5 As shown, a gluing member 4 and a cutting member 5 are further provided in the forward direction of the conveying member 1. The gluing member 4 applies film to the surface of the vacuum insulation panel 7, and the cutting member 5 cuts off the excess film material on the surface of the vacuum insulation panel 7. As the vacuum insulation panel 7 is transmitted, a film roll 3 is also installed on the conveying member 1. The gluing member 4 presses the free end of the film roll 3 tightly against the surface of the vacuum insulation panel 7 to ensure that the surface of the vacuum insulation panel 7 is tightly attached. The dust removal member 2 removes dust from the vacuum insulation panel 7 in advance, which can greatly improve the gluing effect on the surface of the vacuum insulation panel 7 to avoid dust. The dust is not cleaned properly, resulting in the problem of loose fitting; the adhesive part 4 can be used in many ways, such as using a plate pressing method to press the film against the surface of the vacuum insulation panel 7, so that the film on the surface of the vacuum insulation panel 7 fits more tightly, but this method occupies a larger space, so the present application preferably uses a pressing roller method, by adjusting the height of the pressing roller, when the vacuum insulation panel 7 moves to the pressing roller, the pressing roller presses the film against the surface of the vacuum insulation panel 7, so that the film on the surface of the vacuum insulation panel 7 fits more tightly. It should be noted that one side of the film has a glue layer for easy fitting.

[0042] like Figure 5-Figure 7As shown, the cutting piece 5 can use a cutter 54 that moves vertically downward to directly cut off the excess film at the edge of the vacuum insulation panel 7, but this method requires changing the conveying position of the conveying member 1 to ensure that a gap is reserved at the cutter 54, but the present application is a simple cutter 54 structure, and the cutting piece 5 preferably includes a bracket 51 arranged on the conveying member 1, and a moving device 52 installed on the bracket 51, and a cutter 54 is provided on the moving device 52. The bracket 51 is also provided with a negative pressure device 53 for adsorbing the cut free end of the film. The moving device 52 can be driven by a servo motor and a lead screw, or by a linear motor, which can drive the cutter 54 to move horizontally, thereby cutting the film at the edge of the vacuum insulation panel 7 to ensure that the vacuum insulation panel 7 is film-sticked. The negative pressure device 53 can ensure that after the film is cut, its free end is fixed to avoid the subsequent vacuum insulation panel 7 from being unable to implement the film-sticking operation. The negative pressure device 53 can be in the form of a straw, a suction cup or a suction nozzle.

[0043] Specifically, when the vacuum insulation panel 7 passes through the cutting piece 5, the pressure roller presses the film against the surface of the vacuum insulation panel 7 to realize the film laminating operation. After the film laminating of the vacuum insulation panel 7 is completed, the negative pressure device 53 is started to adsorb and fix the film. At this time, the moving device 52 drives the cutter 54 to move horizontally, and the adsorption and fixation method of the negative pressure device 53 can ensure that the film is cut more neatly. Until the moving device 52 drives the cutter 54 to cut the film, the conveying member 1 can directly convey the vacuum insulation panel 7 forward. Until the subsequent vacuum insulation panel 7 moves to the cutting piece 5 again, the pressure roller presses the film against the surface of the vacuum insulation panel 7, and the negative pressure device 53 is released, thereby realizing the cyclic film laminating and cutting operation.

[0044] like Figure 1 , Figure 2 and Figure 5 As shown, an adjusting member 6 is also provided on the conveying member 1. When the vacuum insulation panel 7 with film pasting is being transported, the adjusting member 6 pushes the vacuum insulation panel 7 to the middle of the conveying member 1 to ensure the conveying position. The adjusting member 6 can be in the form of a push plate, such as extending a telescopic cylinder to drive the conveying plate to move to the middle of the conveying member 1, or bevel edges can be set at both ends of the push plate to guide the vacuum insulation panel 7 to the middle of the conveying member 1.

[0045] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
