Description

Technical Field

[0001] The utility model belongs to the technical field of processing and production, in particular to a glue coating device. 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.

[0029] The gluing device of the utility model is further described in detail below in conjunction with the accompanying drawings and specific embodiments:

[0030] 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 200 is defined as the front-to-back direction, and the width direction of the aerogel felt 200 is defined as the left-to-right direction.

[0031] Specific embodiment 1: Figure 1-Figure 3 As shown, the glue coating device of the utility model includes a mounting frame 100; a glue coating component 10, a glue supply component, and a glue scraping component 20 are arranged on the mounting frame 100, wherein the glue supply component guides the glue 300 to the glue coating component 10, and the glue scraping component 20 is arranged adjacent to the glue coating component 10, and the glue scraping component 20 removes part of the glue 300 on the glue coating component 10, so that the glue 300 on the glue coating component 10 forms a glue pattern, and the glue coating component 10 can transfer the glue pattern to the aerogel felt 200.

[0032] In this way, when in use, the glue supply component guides the glue 300 to the glue coating component 10, the glue scraping component 2 removes part of the glue 300 on the glue coating component 10 to form a glue pattern, and the glue coating component 10 transfers the glue pattern to the aerogel felt 200. The glue pattern reserves an escape channel for water vapor evaporation, thereby avoiding bulging or stratification caused by water vapor being unable to escape when the multi-layer aerogel felt 200 is fixed by the glue, thereby ensuring the appearance quality of the multi-layer aerogel felt.

[0033] Specifically, the glue coating component 10 is a cylindrical glue coating roller 11 rotatably mounted on a mounting frame 100, and a glue coating surface is provided on the circumferential outer edge of the glue coating roller 11, and a glue pattern is formed on the glue coating surface. In this embodiment, the glue coating roller 11 is a rubber roller; the glue scraping component 20 is a metal roller 21 rotatably mounted on the mounting frame 100, and the metal roller is arranged parallel to the glue coating roller. The metal roller 21 is provided with a plurality of annular protrusions 23 spaced along its axial direction, and annular grooves 24 are formed between adjacent annular protrusions 23, and the annular protrusions are arranged in contact with the glue coating surface to prevent the glue from adhering to the glue coating surface. The rotation directions of the glue coating roller 11 and the metal roller 21 are opposite. In this embodiment, the glue coating roller 11 rotates clockwise, and the metal roller 21 rotates counterclockwise, so that the glue passes through the gap between the annular groove of the metal roller and the glue coating surface and adheres to the glue coating surface to form a striped glue pattern.

[0034] In some embodiments, the glue supply assembly includes a glue storage tank, which is used to hold glue. Flanges are fixed at both ends of the metal roller, which protrude from the circumferential outer edge of the metal roller 21 and are close to the glue roller 11, so that the glue roller 11, the metal roller 21, and the flanges at both ends of the metal roller are jointly formed to form a storage tank 70 for holding glue 300. After the glue roller 11 is rotated out of the storage tank 70, under the joint action of the metal roller 21, a striped glue pattern is formed at intervals in the axial direction of the glue roller 11. That is, a striped glue pattern is formed on the glue roller 11, and the stripes are formed at intervals along the axial direction of the glue roller 11.

[0035] In some embodiments, the glue supply assembly includes a raw material barrel (not shown) containing glue liquid 300 , and the raw material barrel continuously supplies glue to the receiving groove 70 , so that the glue coating device 100 can continuously coat the workpiece 200 with glue.

[0036] In order to facilitate automation, in this embodiment, the gluing device further includes a driving assembly 40, which is arranged on the mounting frame 100, and includes a driving motor 41, a driving gear 13 and a transmission chain 60. The driving gear 13 is connected to one end of the gluing roller, and the driving motor is connected to the driving gear 13 through the transmission chain 60. A transmission gear 42 is fixed to the output shaft of the driving motor. Specifically, the driving motor 41 works to drive the transmission gear 42 to rotate, and the transmission gear drives the driving gear 13 to rotate through the transmission chain 60, so that the driving motor 41 drives the gluing roller 11 to rotate.

[0037] In some embodiments, the glue coating roller 11 and the metal roller 21 are driven by gear meshing. In this embodiment, a driving gear 12 is fixed on the rotating shaft of the glue coating roller 11, and the driving gear 12 is arranged on the right side of the driving gear 13. A driven gear 22 is fixed at one end of the metal roller 21, and the driving gear 12 is meshed with the driven gear 22 for transmission, so that the glue coating roller 11 and the metal roller 21 share a driving motor 41, simplifying the structural setting of the glue coating device. In this embodiment, the linear speed of the glue coating roller 11 and the metal roller 21 is the same. In other embodiments, by adjusting the diameters of the metal roller 21 and the glue coating roller 11, the linear speed of the outer edge of the metal roller 21 is less than or greater than the linear speed of the glue coating surface of the glue coating roller 11, so that the annular rack of the metal roller 21 scrapes the glue 300 on the glue coating roller 11.

[0038] In some embodiments, a limiting member 30 is also provided on the mounting frame 100. The limiting member 30 is arranged on the side of the glue coating roller 11 away from the accommodating groove 70, and the limiting member 30 is arranged close to the glue coating roller 11. A gap is formed between the limiting member 30 and the glue coating roller 11 for the air gel felt 200 to pass through.

[0039] In some embodiments, the limiting member 30 is a limiting roller 31 correspondingly arranged below the glue coating roller 11. The limiting roller 31 is rotatably arranged on the mounting frame 100. The outer peripheral surface of the limiting roller 31 is cylindrical. A gap is formed between the limiting roller 31 and the glue coating roller 11 for the air gel felt 200 to pass through.

[0040] The limiting roller 31 rotates in the opposite direction to the glue coating roller 11. In this embodiment, the limiting roller 31 rotates counterclockwise. The setting of the limiting roller 31 can limit the passing aerogel felt 200, so that the aerogel felt 200 is fully in contact with the glue coating roller 11, and ensure that the adhesive on the glue coating roller 11 is smoothly transferred to the aerogel felt 200. In this embodiment, the outer peripheral surfaces of the limiting roller 31 and the glue coating roller 11 are both cylindrical surfaces, so that the aerogel felt 200 can be prevented from wrinkling and twisting during the transmission and gluing process, thereby improving the yield rate of the multi-layer aerogel felt 200.

[0041] In some embodiments, in order to facilitate the rotational drive of the limiting roller 31 , in this embodiment, a limiting gear 32 is fixed to one end of the limiting roller 31 , and the limiting gear 32 is transmission-connected to the driving motor 41 via a transmission chain 60 .

[0042] In some embodiments, in order to facilitate the adjustment of the transmission direction of the transmission chain 60 and the tightness of the transmission chain 60, in this embodiment, a guide gear 50 is rotatably provided on the mounting frame 100, and the transmission chain 60 bypasses the guide gear 50. The transmission path of the transmission chain 60 is changed through the guide gear 50 to avoid the transmission chains 60 being too close to each other.

[0043] It should be noted that the gluing device for the multi-layer aerogel felt 200 of the utility model can be used for continuous gluing of the rolled aerogel felt 200 and can also be used for gluing of the sheet aerogel felt 200 .

[0044] When the gluing device of the utility model is in use, the driving motor 41 drives the transmission gear 42 to rotate clockwise, the transmission gear 42 drives the transmission chain 60 to rotate, the transmission chain 60 drives the limiting roller 31 to rotate counterclockwise, and drives the gluing roller 11 to rotate clockwise; the gluing roller 11 and the metal roller 21 are driven by gear meshing, so that the gluing roller 11 drives the metal roller 21 to rotate counterclockwise, after the gluing roller 11 rotates and rotates out of the accommodating groove 70, the glue 300 passes through the gap between the annular groove 24 of the metal roller 21 and the gluing surface of the gluing roller 11 and forms a striped glue pattern on the gluing surface of the gluing roller 11; the aerogel felt 200 passes through the gap between the gluing roller 11 and the limiting roller 31, and the gluing roller 11 transfers the striped glue pattern on the outer peripheral surface to one side of the aerogel felt 200, so that one side of the aerogel felt 200 is coated with striped glue. In this way, when the multi-layer aerogel felt 200 is bonded together by an adhesive, the adhesive gradually dries, and water vapor evaporates from the adhesive. The striped adhesive arranged at intervals reserves an escape channel for water vapor, avoiding bulging when the multi-layer aerogel felt 200 is bonded, thereby ensuring the appearance quality of the multi-layer aerogel felt 200; not only that, it can also save the amount of adhesive and alleviate adhesive overflow. Moreover, in the utility model, the aerogel felt 200 passes through the gap between the glue coating roller 11 and the limiting roller 31, thereby avoiding wrinkles, twists, etc. of the aerogel felt 200 during the transmission and gluing process, thereby improving the yield rate.

[0045] Specific embodiment 2, as Figure 4 As shown, different from the first embodiment, a plurality of first protrusions 81 are provided on the outer peripheral surface of the metal roller 80, the first protrusions 81 are staggered in the axial direction of the metal roller 80, the first protrusions 81 are staggered in the circumferential direction of the metal roller 80, first grooves 82 are formed between adjacent first protrusions 81, and the first protrusions 81 are arranged in close contact with the outer peripheral surface of the rubber coating roller.

[0046] After the glue coating roller rotates and rotates out of the accommodating groove, the glue passes through the gap between the first groove 82 of the metal roller 80 and the glue coating surface of the glue coating roller and adheres to the glue coating surface of the glue coating roller to form a block glue pattern. When the aerogel felt passes through the gap between the glue coating roller and the limiting roller, the glue coating roller transfers the block glue pattern on the outer peripheral surface to one side of the aerogel felt, so that one side of the aerogel felt is coated with adhesive blocks arranged at intervals, and water vapor escape space is formed between adjacent adhesive blocks, thereby avoiding bulging due to lack of water vapor storage space when the multi-layer aerogel felt is bonded, thereby ensuring the appearance quality of the multi-layer aerogel felt.

[0047] Specific embodiment three, as Figure 5As shown, different from the first embodiment, a plurality of first convex rings 91 are axially spaced apart on the metal roller 90, a first brushing ring is formed between adjacent first convex rings 91, the first brushing ring includes first protrusions 92 uniformly distributed circumferentially on the metal roller 90, a first groove 93 is formed between adjacent first protrusions 92, the first convex rings 91 are fitted against the outer peripheral surface of the glue coating roller, and the first protrusions 92 of the first brushing ring are fitted against the outer peripheral surface of the glue coating roller.

[0048] After the glue coating roller rotates and rotates out of the accommodating groove, the glue passes between the first groove 93 of the metal roller 90 and the glue coating surface of the glue coating roller and adheres to the outer peripheral surface of the glue coating roller to form a block glue pattern. When the aerogel felt passes through the gap between the glue coating roller and the limiting roller, the glue coating roller transfers the block glue pattern on the outer peripheral surface to one side of the aerogel felt, so that one side of the aerogel felt is coated with adhesive blocks arranged at intervals, and water vapor escape space is formed between adjacent adhesive blocks, thereby avoiding bulging due to lack of water vapor storage space when the multi-layer aerogel felt is bonded, thereby ensuring the appearance quality of the multi-layer aerogel felt.

[0049] In the above embodiment, the raw material barrel supplies glue to the containing tank, and then the glue coating roller rotates through the containing tank, so that the glue coating roller is adhered with glue; in other embodiments, glue can also be directly coated on the glue coating roller through the raw material barrel.

[0050] In the above embodiments, the limiting member is a limiting roller, and in other embodiments, the limiting member is a conveyor belt, which is arranged below the glue coating roller, and the conveying direction of the conveyor belt at the glue coating roller is the same as the tangent of the rotation direction of the glue coating roller at the corresponding position of the conveyor belt.

[0051] In the above embodiment, a limiting roller is arranged at a corresponding interval below 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 aerogel felt to pass through, and the limiting roller and the glue coating roller have opposite rotation directions; in other embodiments, the limiting roller may not be arranged. In this case, the rolled aerogel felt is coated with glue, and the aerogel felt is in a tensioned state when passing through the glue coating roller.

[0053] In the above embodiment, a guide gear is rotatably provided on the mounting frame, and the transmission chain passes around the guide gear; in other embodiments, the guide gear may not be provided.

[0054] In the above embodiment, the glue coating roller is a rubber roller; in other embodiments, the glue coating roller may also be a plastic roller.
