Description

Technical Field

[0001] The present invention relates to the technical field of aerogel felts, and specifically relates to an automatic powder-sprinkling aerogel felt. Background Art

[0002] An aerogel felt is a flexible thermal insulation felt made of nano-silica or metal aerogel as the main material and compounded with carbon fiber, ceramic glass fiber cotton or pre-oxidized fiber felt through a special process. When the aerogel felt is actually used, powder needs to be sprinkled on its surface, and the purpose of powder sprinkling can enhance its hydrophobicity and heat insulation performance.

[0003] At present, after the production of the aerogel felt, it will be packed into rolls. When this rolled aerogel felt is cut according to usage, powder sprinkling still needs to be achieved manually, and the powder amount is completely controlled by manual feeling. Therefore, this powder-sprinkling method is difficult to ensure the uniformity of the powder amount of the selected part of the aerogel felt. At the same time, when the aerogel powder is sprinkled onto the surface of the aerogel felt, it is easily interfered by the external air flow, which will cause waste of the aerogel powder.

[0004] In view of this, an automatic powder-sprinkling aerogel felt is designed to solve the above problems. Summary of the Invention

[0017] 2. By providing a triangular plate on the powder spreading mechanism, after the powder spreading mechanism evenly scatters the aerogel powder on the surface of the aerogel felt, the problem of excessive powder on the surface of the aerogel felt caused by too large a gap in the powder spreading mechanism can be quickly transferred and stored through the two guiding members towards the two groups of powder recovery mechanisms under the horizontal scraping action of the triangular plate, thus avoiding waste of excessive aerogel powder.

[0018] 3. The present invention limits and constrains the two sides of the aerogel felt after being stretched by arranging two groups of felt edge beam position mechanisms. After the selected part of the aerogel felt is stretched, the two groups of felt edge beam position mechanisms can straighten the aerogel felt forcibly. At this time, the part after passing through the two groups of felt edge beam position mechanisms can perfectly print the aerogel powder, thereby avoiding the phenomenon of uneven powder scattering caused by abnormal shaking during the stretching of the aerogel felt.

DETAILED DESCRIPTION

[0021] To make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0022] It is to be understood that these descriptions are illustrative only and are not intended to limit the scope of the invention.

[0023] An automatic powder-sprinkling aerogel felt provided by some embodiments of the present invention will be described below with reference to the accompanying drawings. Example 1:

[0024] Combine Figures 1 to 10 As shown, the present invention provides an automatic powder-sprinkling aerogel felt, comprising an aerogel felt 100 and two sets of felt edge binding mechanisms 300, a felt roller clamping mechanism 200 arranged outside the aerogel felt 100, and a powdering mechanism 400 arranged between the two sets of felt edge binding mechanisms 300, wherein one set of felt edge binding mechanisms 300 is arranged on the felt roller clamping mechanism 200 and two sets of powder recovery mechanisms 500 are arranged on the two sets of felt edge binding mechanisms 300, the felt roller clamping mechanism 200 is used to adapt and clamp the aerogel felt 100 and provide a support platform for one set of felt edge binding mechanisms 300, the two sets of felt edge binding mechanisms 300 are arranged on both sides of the powdering mechanism 400, and are used to straighten and constrain the side edges of the stretched part of the aerogel felt 100, the powdering mechanism 400 is used to evenly sprinkle powder on the surface of the stretched part of the aerogel felt 100, and the two sets of powder recovery mechanisms 500 are used to store the aerogel powder scraped off the aerogel felt 100.

[0025] The powder sprinkling mechanism 400 includes a storage housing 450 horizontally placed directly above the stretched portion of the aerogel felt 100, two covers 410 provided at both ends of the storage housing 450, a limiting rod 440 provided inside the two covers 410, two partition plates 4505 provided inside the cavity of the storage housing 450, two gap-expanding pads 4507 movably installed outside the limiting rod 440 and located between the two partition plates 4505, two grid pads 4506 installed between the two covers 410 and at the bottom end of the storage housing 450, two guiding members 4602 provided at both ends of the triangular plate 4601, and the guiding member 4602 is integrally in an L-shaped structure, and a through hole is provided inside the guiding member 4602, and the through hole communicates with the feeding hole 530, and is used to provide a transfer path for the aerogel powder; A groove 420 is provided on the inner wall of the cover 410 and a tension spring 430 is provided inside the groove 420. A pressurizing beam rod 4508 is movably installed in the two grooves 420, and the bottom end of the groove 420 is connected to the pressurizing beam rod 4508, and the top end of the groove 420 is connected to the inner wall of the tension spring 430. A fourth bolt 4501 is provided at the top of the storage housing 450, and the bottom end of the fourth bolt 4501 is movably installed inside the pressurizing beam rod 4508, and the fourth bolt 4501 is used to provide an active driving force for the lifting of the pressurizing beam rod 4508; The pressurizing beam rod 4508 is used to apply a constant squeezing force to the two gap-expanding pads 4507, and a rectangular horizontal groove is provided inside the gap-expanding pad 4507; The limiting rod 440 is movably installed in the rectangular horizontal groove.

[0026] The grid pad 4506 is composed of a rubber strip and an elongated shaft rod, and the bottom ends of the two rubber strips are adapted and fitted; Two material cavities 4509 are provided inside the storage housing 450 for storing the aerogel powder; The powder sprinkling mechanism 400 further includes a foot pad 4502 provided on the outside of the storage housing 450, a pin 4504 provided inside the foot pad 4502, a fifth bolt 4503 movably installed inside the pin 4504, a support plate 460 movably installed outside the pin 4504, and a triangular plate 4601 installed at the bottom of the support plate 460.

[0027] When the fourth bolt 4501 is reversed, the pressure-boosting beam 4508 is pressed down, and the pressure-boosting beam 4508 pushes the two gap-expanding pads 4507 to descend synchronously. At this time, the bottom ends of the two gap-expanding pads 4507 will stretch the two grid pads 4506 apart. The gaps between the two grid pads 4506 after expansion can provide a scattering path for the aerogel powder stored in the two material cavities 4509. As the selected portion of the aerogel felt 100 is continuously stretched, the resonance generated during the transverse movement of the stretched portion of the aerogel felt 100 along the two sets of felt edge binding mechanisms 300 will be indirectly transmitted to the material storage housing 450, thereby promoting the continuous scattering of the aerogel powder. The triangular plate 4601 arranged on the outside of the material storage shell 450 cooperates with the two guiding pieces 4602 to scrape the excess aerogel powder on the surface of the aerogel felt 100, and the excess aerogel powder is transferred along the inner side of the triangular plate 4601 along the extension direction of the stretched part of the aerogel felt 100. Finally, the aerogel powder will enter the two guiding pieces 4602, and the aerogel powder remaining on the surface of the aerogel felt 100 can be kept in a uniform state. Embodiment 2:

[0028] Combine Figures 1 to 3 As shown, based on Example 1, the felt roller clamping mechanism 200 includes a core rod 230 inserted into the rolled aerogel felt 100, a beam frame 210 provided at one end of the core rod 230, a plug 240 provided at the other end of the core rod 230, a guide rod 250 installed on the plug 240, and a first spring 260 provided outside the guide rod 250, and the end of the guide rod 250 away from the plug 240 is adapted to penetrate into the beam frame 210; A slide groove 220 is formed inside the beam 210, and a plug 240 is movably installed in the slide groove 220; The felt roller clamping mechanism 200 also includes a load-bearing plate 270 installed on the outside of the beam frame 210 and a first bolt 2702 arranged in the load-bearing plate 270, and a transverse groove 2701 is opened in the load-bearing plate 270, a sliding rod 290 movably installed in the transverse groove 2701, and a bracket 280 arranged on the outside of the sliding rod 290 and extending through the load-bearing plate 270.

[0029] Preferably, one end of the first spring 260 is fixedly mounted on the plug 240 , and the other end of the first spring 260 is adapted to bear pressure on the beam 210 ; When it is necessary to select the area for scattering aerogel powder on the stretched part of the aerogel felt 100, loosen the first bolt 2702 in advance, and then stretch the bracket 280 outward until a larger gap is opened between the two sets of felt edge positioning mechanisms 300 and the powder spreading mechanism 400 and the core rod 230. At this time, the aerogel felt 100 is stretched and the part after passing through the bottom of the powder spreading mechanism 400 can increase the area for scattering aerogel powder. Embodiment 3:

[0030] Combined Figures 4 to 10 As shown, on the basis of Embodiment 1, the felt edge beam mechanism 300 includes a load-bearing pad 370, a base 310 disposed outside the cover 410, a second bolt 3101 disposed at the top end of the base 310, a slide base 3102 disposed inside the base 310, a second spring 3103 disposed at the top of the slide base 3102, a shaft rod 320 installed inside the slide base 3102, an anti-sticking sleeve roller 330 movably installed outside the shaft rod 320, a clamp 350 disposed outside the slide base 3102, and a scraper 3501 installed on the clamp 350.

[0031] Preferably, the second bolt 3101 is used to control the inclination angle between the cover 410 and the stretched part of the aerogel felt 100. When the stretched part of the aerogel felt 100 passes through the gap between the anti-sticking sleeve roller 330 and the bottom plate 340, the limiting inner pad 360 pressed by the third spring 3602 will provide anti-skew protection for the stretched side edge of the aerogel felt 100.

[0032] The bottom end of the scraper 3501 is adapted to fit the outer wall of the anti-sticking sleeve roller 330, a locking bolt 3701 disposed in the load-bearing pad 370, and the locking bolt 3701 is used to fix the distance-adjusting plate 510, a base 380 installed at the bottom of the bottom plate 340, a cutting knife 390 movably installed outside the base 380, a third bolt 3801 penetrating into the cutting knife 390 and connected to the inside of the base 380, and a gasket 3802 disposed outside the third bolt 3801 and pressing the cutting knife 390; A bottom plate 340 fixedly installed at the bottom of the base 310, a limiting inner pad 360 movably installed in the top groove of the bottom plate 340, an end rod 3601 installed at the outer end of the limiting inner pad 360 and penetrating into the inside of the bottom plate 340, and a third spring 3602 disposed on the end rod 3601. The anti-sticking sleeve roller 330 cooperates with the bottom plate 340 to straighten and constrain the side edges of the stretched part of the aerogel felt 100; The cutting edge at the top of the cutting knife 390 is adapted to fit the bottom of the stretched part of the aerogel felt 100; When the stretched aerogel felt 100 with different thicknesses is stretched, the stretched part will laterally move out along the gap between the bottom plate 340 and the anti-sticking sleeve roller 330. At this time, the impurities adhered to the surface of the anti-sticking sleeve roller 330 will be scraped off by the cutting edge at the bottom of the scraper 3501, and the two bottom plates 340 and the two anti-sticking sleeve rollers 330 evenly distributed on both sides of the stretched aerogel felt 100 can straighten it forcibly. At this time, the aerogel powder overall scattered by the powder scattering mechanism 400 can be evenly scattered on the surface of the forcibly straightened part of the aerogel felt 100. Embodiment 4:

[0033] Combined Figure 4 and Figure 9As shown in the above embodiments, the powder recovery mechanism 500 includes an adjustable distance plate 510 movably installed inside the load-bearing pad 370, a return material bin 520 installed at the outer end of the adjustable distance plate 510, a bracket 540 installed on the top of the adjustable distance plate 510, a linkage shaft 550 movably installed inside the bracket 540, an auxiliary rotating roller 560 installed outside the linkage shaft 550, and an exhaust assembly 570 movably installed at the top of the inner end of the return material bin 520; At the top of the outer end of the return material bin 520, a feed hole 530 is provided, and the feed hole 530 is used to absorb excessive aerogel powder.

[0034] Preferably, an exhaust groove is provided at the top of the inner end of the return material bin 520. The exhaust assembly 570 is composed of a vertical shaft rod, a gear, and an impeller. The vertical shaft rod is movably installed in the middle of the exhaust groove. The linkage shaft 550 is composed of a horizontal shaft rod and a deflection gear, and the deflection gear is fitted and engaged with the gear; When the aerogel felt 100 is stretched, the auxiliary rotating roller 560 will automatically rotate when it fits against the bottom of the stretched part of the aerogel felt 100, and the exhaust assembly 570 will be driven. Eventually, the air in the inner cavity of the return material bin 520 will be discharged outward, and finally, the aerogel powder guided along the guiding member 4602 and the feed hole 530 will be actively sucked in.

[0035] The working principle and usage process of the present invention: First, pull the plug 240 outward until the plug 240 and the beam frame 210 are expanded to the maximum gap. Then, place the rolled-up aerogel felt 100 in the gap. Next, insert one end of the core rod 230 along the horizontal hole inside the plug 240 until the core rod 230 penetrates into the aerogel felt 100. Finally, the end of the core rod 230 that penetrates outside the aerogel felt 100 will be inserted into the beam frame 210; According to the requirement of powder sprinkling on the surface of the aerogel felt 100, by loosening the first bolt 2702, then pulling the bracket 280 and the slide rod 290 outward. At this time, a group of felt edge positioning mechanisms 300 installed in the bracket 280 will cooperate with the powder sprinkling mechanism 400 to move horizontally outward. At this time, the powder sprinkling mechanism 400 will maintain a certain powder sprinkling distance from the exposed part of the stretched aerogel felt 100, and the two felt edge positioning mechanisms 300 can effectively restrain the two sides of the stretched aerogel felt 100; Then adjust the fourth bolt 4501 to reverse, at this time the boost beam 4508 is under pressure to push the two gap expansion pads 4507 downward, and the two gap expansion pads 4507 will open the two grid pads 4506. At this time, a gap of a certain width will be exposed between the two grid pads 4506, and as the aerogel felt 100 continues to stretch outward, the aerogel powder stored in the two material cavities 4509 will naturally spray along the gap between the two grid pads 4506 until the aerogel powder is sprinkled on the surface of the aerogel felt 100. At the same time, adjust the fourth bolt 4501 to reverse, at this time the boost beam 4508 is under pressure to push the two gap expansion pads 4507 downward, and the two gap expansion pads 4507 will open the two grid pads 4506. At this time, a gap of a certain width will be exposed between the two grid pads 4506. As the aerogel felt 100 continues to stretch outward, the aerogel powder stored in the two material cavities 4509 will naturally spray along the gap between the two grid pads 4506 until the aerogel powder is sprinkled on the surface of the aerogel felt 100. The fifth bolt 4503 is reversed, and the pin 4504 movably mounted at the bottom end of the fifth bolt 4503 causes the support plate 460 and the triangular plate 4601 to descend. At this time, the distance between the bottom end of the triangular plate 4601 and the powder-spreading surface of the aerogel felt 100 can be effectively adjusted. As the aerogel felt 100 continues to stretch, the bottom end of the triangular plate 4601 will also scrape off excess aerogel powder on the surface of the aerogel felt 100, and the scraped aerogel powder will be transferred along the two guide pieces 4602 to the two feed holes 530. As the aerogel felt 100 stretches outward and the bottom of the aerogel felt 100 assists the two rotation-assisting rollers 560 in rotating, the exhaust assembly 570 driven by the linkage shaft 550 rotates, and the inner cavity of the return bin 520 exhausts air outward. At this time, the aerogel powder entering the two guide members 4602 is quickly sucked into the inner cavity of the return bin 520 under the action of the airflow. After the aerogel felt 100 is stretched to a selected size, the cutting knife 390 is inserted toward the base 380 along the auxiliary roller 560 until the cutting knife 390 is movably mounted on the protrusion at the bottom of the base 380, and the cutting knife 390 is fixed to the base 380 using the third bolt 3801 and the gasket 3802. At this time, the auxiliary roller 560 will be located between the cutting knife 390 and the base 380. After the surface of the stretched part of the aerogel felt 100 is evenly powdered, an inclined pressure can be applied to one side of the aerogel felt 100 along the blade at the top of the cutting knife 390. Finally, the side of the aerogel felt 100 can be quickly cut by the blade at the top of the cutting knife 390.

[0036] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the claims and their equivalents.
