Description

Technical Field

[0001] The utility model belongs to the technical field of aerogel felt processing and production, in particular to a glue coating device for aerogel felt composite. Background Art

[0002] Aerogel felt is a felt structure formed by combining aerogel raw materials with fiber felt using a special process. Since aerogel felt has excellent thermal insulation properties, is resistant to high temperatures and does not produce harmful gases, aerogel felt products are used as high-efficiency thermal insulation materials in many fields such as the new energy vehicle industry, home appliances, and smart electronic products.

[0003] When thicker insulation products are needed, single-layer aerogel felt is often difficult to meet the requirements due to its insufficient thickness. At this time, multiple single-layer aerogel felts need to be stacked to achieve the target thickness, and the multiple layers of aerogel felt are glued together with adhesive to increase the connection strength between the two adjacent layers of aerogel felt. If the adhesive is fully applied between the two adjacent layers of aerogel felt, the water vapor in the adhesive evaporates during drying, and the aerogel felt is prone to bulging, which not only affects the appearance quality of the multi-layer aerogel felt, but also affects the thermal insulation performance of the aerogel felt. Utility Model Content

[0004] In view of this, the purpose of the utility model is to provide a glue coating device for aerogel felt composite, so as to solve the problem in the prior art that the adhesive between two adjacent layers of aerogel felt is easily bulged during drying, thereby affecting the thermal insulation performance of the multi-layer aerogel felt.

[0028] The following is a further detailed description of an aerogel felt composite gluing device of the utility model in conjunction with the accompanying drawings and specific embodiments:

[0029] The gluing device of the present application is suitable for gluing a multi-layer aerogel felt. In order to facilitate the structural description of the gluing device, the moving direction of the aerogel felt 500 is defined as the front-to-back direction, and the width direction of the aerogel felt 500 is defined as the left-to-right direction.

[0030] Specific embodiment 1, as Figure 1 The utility model discloses a glue coating device for aerogel felt composite, which includes a mounting frame 400, on which a glue coating component 120, a glue supply component 140, and a glue scraping structure 160 are arranged; wherein the glue coating component 120 obtains glue 600 from the glue supply component 140, and the glue scraping structure 160 is arranged on one side of the glue coating component 120, and the glue scraping structure 160 scrapes off part of the glue 600 on the glue coating component 120, so that the glue 600 on the glue coating component 120 forms a glue pattern, and the glue coating component 120 can transfer the glue pattern to the workpiece.

[0031] When in use, the glue coating component 120 obtains the glue 600 from the glue supply component 140, and the glue scraping structure 160 scrapes off part of the glue 600 on the glue coating component 120 to form a glue pattern. The glue coating component 120 transfers the glue pattern to the aerogel felt 500. The glue pattern reserves an escape channel for water vapor evaporation, thereby avoiding bulging or stratification caused by the inability of water vapor to escape when the multi-layer aerogel felt 500 is fixed by the glue 600, thereby ensuring the appearance quality of the multi-layer aerogel felt 500.

[0032] Specifically, the glue coating assembly 120 is a cylindrical glue coating roller 121 rotatably mounted on the mounting frame 400. The circumferential outer edge of the glue coating roller 121 is provided with a glue coating surface, and a glue pattern is formed on the glue coating surface. The glue scraping structure 160 is a scraper 161 disposed on one side of the glue coating roller 121. The end of the scraper 161 facing the glue coating roller 121 is formed with a plurality of rectangular teeth 163 disposed at intervals. The rectangular teeth 163 are disposed in close contact with the glue coating surface to scrape off the glue 600 on the glue coating surface of the glue coating roller 121 and form a striped glue pattern on the glue coating surface. In this embodiment, the glue coating roller 121 is a rubber roller.

[0033] In some embodiments, the glue coating assembly 120 also includes a limiting roller 123 arranged above the glue coating roller 121 and spaced correspondingly from the glue coating roller 121. The limiting roller 123 is cylindrical, and a gap is formed between the limiting roller 123 and the glue coating roller 121 for the workpiece to pass through. The rotation directions of the glue coating roller 121 and the limiting roller 123 are opposite.

[0034] In some embodiments, the glue supply component 140 is a receiving groove 141 fixed on the mounting frame 400, the receiving groove 141 is used to contain the glue 600, the glue coating roller 121 is arranged above the receiving groove 141, and the part of the glue coating roller 121 close to the receiving groove 141 is immersed in the glue 600 contained in the receiving groove 141, so that the glue coating surface of the glue coating roller 121 contacts the liquid surface of the glue 600, so that the glue 600 adheres to the glue coating surface after the glue coating roller 121 rotates, and the glue scraping structure 160 is arranged on the rotation path of the glue coating roller 121, and is arranged after the glue coating roller 121 rotates out of the glue 600 and before it contacts the workpiece.

[0035] In some embodiments, the glue supply assembly 140 includes a raw material barrel (not shown) containing glue liquid 600, and the raw material barrel continuously supplies glue to the receiving groove 141, so that the glue coating device can continuously coat the workpiece with glue.

[0036] In order to facilitate the rotation of the glue coating roller 121, in this embodiment, the glue coating device further includes a driving assembly 110, which is arranged on the mounting frame 400. The driving assembly 110 includes a driving motor 111, a driving gear 122 and a transmission chain 113. The driving gear 122 is connected to one end of the glue coating roller 121. The output shaft of the driving motor 111 is provided with a connecting gear 112, which is connected to the driving gear 122 through the transmission chain 113 and is configured to drive the glue coating roller 121 to rotate. In addition, a transmission gear 124 is provided on the limiting roller 123, and the driving motor 111 is connected to the transmission gear 124 through a transmission connection and is configured to drive the limiting roller 123 to rotate.

[0037] In some embodiments, in order to facilitate the adjustment of the transmission direction of the transmission chain 113 and the tightness of the transmission chain 113, in this embodiment, a guide gear 150 is rotatably arranged on the mounting frame 400, and the guide gear 150 is arranged on one side of the rubber coating tube. The transmission chain 113 passes around the guide gear 150, and the transmission path of the transmission chain 113 is changed by the guide gear 150 to avoid the transmission chains 113 being too close to each other.

[0038] In some embodiments, the scraper 161 is fixed on the mounting frame 400, and the scraper 161 is located on the side of the glue coating roller 121 that is rotated out from the glue liquid 600. In order to facilitate the collection of the glue liquid 600 scraped by the scraper 161, in this embodiment, the lower end of the scraper 161 extends into the receiving groove 141, so that the scraped glue liquid 600 passes through the scraper 161 and is guided into the receiving groove 141. In order to guide the glue liquid 600 smoothly on the scraper 161, baffles 162 are fixed on the left and right sides of the scraper 161.

[0039] It should be noted that the gluing device for the multi-layer aerogel felt 500 of the utility model can be used for continuous gluing of the rolled aerogel felt 500, and can also be used for gluing of the sheet aerogel station.

[0040] When the gluing device of the utility model is in use, the driving motor 111 drives the connecting gear 112 to rotate counterclockwise, the connecting gear 112 drives the transmission chain 113 to rotate, the transmission chain 113 drives the limiting roller 123 to rotate counterclockwise, and the transmission chain 113 drives the gluing roller 121 to rotate clockwise. After the gluing roller 121 rotates, the gluing surface is covered with glue 600, and then the rectangular teeth 163 of the scraper 161 arranged on the side of the gluing roller 121 that is rotated out from the adhesive are used to scrape off part of the glue 600 on the gluing surface of the gluing roller 121, forming a striped glue pattern on the gluing surface. When the aerogel felt 500 passes through the gap between the glue coating roller 121 and the limiting roller 123, the glue coating roller 121 transfers the striped glue pattern to one side of the aerogel felt 500, so that one side of the aerogel felt 500 is coated with a spaced striped glue pattern. In this way, when the adhesive is drying, water vapor evaporates from the adhesive, and the spaced strips of adhesive reserve an escape channel for the water vapor, thereby avoiding bulging of the aerogel felt 500 and ensuring the appearance quality of the multi-layer aerogel felt.

[0041] In the above embodiment, the glue coating assembly includes a limiting roller arranged above the glue coating roller and arranged at a corresponding interval with the glue coating roller. The limiting roller is cylindrical, and a gap is formed between the limiting roller and the glue coating roller for the workpiece to pass through. The glue coating roller and the limiting roller have opposite rotation directions. In other embodiments, the limiting roller may not be set, and the workpiece passes directly over the glue coating roller.

[0042] In the above embodiment, a guide gear is rotatably provided on the mounting frame, the guide gear is provided on one side of the glue coating roller, and the transmission chain is wound around the guide gear; in other embodiments, the guide gear may not be provided.

[0043] In the above-mentioned embodiment, the lower end of the scraper extends into the receiving groove; in other embodiments, the scraper may not extend into the receiving groove.

[0044] In the above-mentioned embodiment, baffles are fixed on the left and right sides of the scraper; in other embodiments, the baffles may not be provided.
