Description

Technical Field

[0001] This utility model relates to the technical field of adhesive fiber composite devices, specifically, to an adhesive fiber composite device with uniform adhesive coating. Background Technology

[0002] Adhesive-fiber composite equipment is a specialized device used to composite adhesives and fiber materials to form composite semi-finished or finished products with specific structures and properties. Its core function is to achieve a strong bond between adhesives and fibers by precisely controlling processes such as adhesive application, fiber spreading, and pressure bonding. It is widely used in fields such as fireproofing, building materials, automotive interiors, and packaging materials.

[0003] When applying adhesive to fiber materials, the fiber materials are usually wound and conveyed on the unwinding roller and guide roller, and then pass through the coating roller. The coating roller dips the adhesive into the glue tank. When the fiber materials pass through the coating roller, the adhesive can be evenly applied to the fiber materials. There is a scraper under the coating roller, which can scrape off the excess adhesive on the coating roller surface, so that the subsequent coating can be even.

[0004] The existing scrapers are all detachably mounted on the device with bolts, which facilitates the replacement and maintenance of the scrapers. However, during installation, because they are installed by bolt threads, after long-term use, the threads may loosen in the threaded holes of the device, causing the scraper to be in a non-horizontal position. Consequently, the contact between the scraper and the coating roller will not be horizontal, and when scraping the coating roller surface, incomplete coating is likely to occur, resulting in uneven coating of the fibers. Utility Model Content

[0005] To overcome the above-mentioned defects, the present invention provides a glue fiber composite device for uniform glue application, which solves the technical problem in the prior art that when the scraper is installed by bolts, if the disassembly and assembly are repeated many times, the bolts are easy to loosen, thus causing the scraper to deviate and make it difficult to adhere to the glue coating roller of the glue fiber composite device, resulting in uneven glue application in the subsequent process.

[0006] According to one aspect, at least one embodiment of the present invention provides a glue fiber composite device for uniformly applying glue, including a glue applicator, on which a glue applicator roller and a conveying roller are installed, and further including a glue scraper, a lifting and adjusting assembly and a support assembly. The glue scraper is mounted on the glue applicator via an installation assembly, the lifting and adjusting assembly is mounted on the glue applicator, and two support assemblies are provided, both of which are mounted on the lifting and adjusting assembly, for supporting the glue scraper after the support assembly has installed the glue scraper.

[0007] Furthermore, the mounting assembly includes mounting rails and mounting brackets. The mounting rails are fixedly mounted on both sides of the glue applicator, and the sides of the mounting rails are provided with grooves. The mounting brackets are L-shaped, and the mounting brackets are slidably mounted in the grooves of both mounting rails. The glue scraper is fixedly mounted on the top of the two mounting brackets.

[0008] Furthermore, the lifting adjustment assembly includes a support cover, a reciprocating screw, a rotating wheel, and a synchronization component. The support covers are fixedly installed on both sides of the glue applicator. The reciprocating screw is rotatably installed in one of the support covers, and a matching crescent-shaped slider is installed on the reciprocating screw. The rotating wheel is coaxially connected to the reciprocating screw, and the synchronization component is located in the other support cover.

[0009] Furthermore, the synchronization component includes a synchronization rod and a synchronization block, the synchronization rod being fixedly installed inside another support cover, and the synchronization block being slidably installed on the synchronization rod.

[0010] Furthermore, the support assembly includes a connecting plate, a rotating shaft, a support rod, and an inclined rod. The connecting plate is fixedly installed between the crescent-shaped slider and the synchronization block. The rotating shaft is rotatably installed on the top of the connecting plate. The support rod is L-shaped, and the bottom end of the support rod is fixedly connected to the top end of the rotating shaft. The inclined rod is obliquely fixedly installed between the rotating shaft and the support rod.

[0011] Furthermore, the scraper is located directly below the coating roller.

[0012] Furthermore, the mounting bracket has a slot at its bottom end, and the top end of the support rod is adapted to the slot.

[0013] Furthermore, the bottom end of the slide groove for mounting the slide rail is open.

[0014] The beneficial effects of this utility model are as follows: In this invention, when installing the scraper, the scraper is first installed directly below the coating roller using the installation assembly. Then, the scraper is slid up to fit against the coating roller. The scraper is then supported by the lifting and adjusting assembly and the support assembly, and raised to fit below the coating roller. Thus, when applying glue, the scraper can scrape off excess adhesive from the outer wall of the coating roller. This installation method ensures that the scraper blade remains horizontal even after multiple installations. Compared to bolt thread installation, it avoids the problem of bolts loosening during repeated installations, thus maximizing the adhesion between the scraper blade and the coating roller.

[0022] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0023] like Figures 1-6 As shown, this invention illustrates a uniformly coated adhesive fiber composite device according to one embodiment of the present invention. The device includes an adhesive applicator 1, on which an adhesive applicator roller 2 and a conveying roller 3 are mounted. It also includes a scraper blade 4, a lifting and adjusting assembly, and a support assembly. The scraper blade 4 is mounted on the adhesive applicator 1 via an mounting assembly. The lifting and adjusting assembly is mounted on the adhesive applicator 1. Two support assemblies are provided, both mounted on the lifting and adjusting assembly, for supporting the scraper blade 4 after it has been mounted on the support assembly.

[0024] like Figure 2 and Figure 6As shown, during the lamination process of fiber fabric and adhesive, one worker first installs the scraper 4 below the coating roller 2 using an installation assembly. The installation assembly includes a mounting rail 5 and a mounting bracket 6. Mounting rails 5 are fixedly installed on both sides of the coating machine 1, and grooves are provided on the sides of the mounting rails 5. The mounting bracket 6 is L-shaped, and the mounting bracket 6 is slidably installed in the grooves of both mounting rails 5. The scraper 4 is fixedly installed on the top of the two mounting brackets 6. Specifically, two workers hold the two mounting brackets 6 respectively. Because the bottom of the groove of the mounting rail 5 is open, the mounting bracket 6 can be slid into the bottom of the mounting rail 5. Since the scraper 4 is located directly below the coating roller 2, the scraper 4 is positioned directly below the coating roller 2 at this time.

[0025] like Figure 3 As shown, after installation, the scraper blade 4 is supported and fixed by the support assembly. The support assembly includes a connecting plate 13, a rotating shaft 14, a support rod 15, and an inclined rod 16. The connecting plate 13 is fixedly installed between the crescent-shaped slider 9 and the synchronization block 12, and the rotating shaft 14 is rotatably installed on the top of the connecting plate 13. The support rod 15 is L-shaped, and its bottom end is fixedly connected to the top end of the rotating shaft 14. The tilting rod 16 is tilted and fixedly installed between the rotating shaft 14 and the support rod 15. Specifically, two workers rotate the rotating shaft 14 on the two connecting plates 13 respectively, thereby rotating the support rod 15 to the bottom end of the mounting bracket 6. Since the bottom end of the mounting bracket 6 has a slot, and the top end of the support rod 15 is adapted to the slot, after rotating the support rod 15 to the bottom of the mounting bracket 6, the mounting bracket 6 is lowered, and the support rod 15 is inserted into the slot of the mounting bracket 6. At this time, the support rod 15 can support the mounting bracket 6, the mounting bracket 6 can also restrict the rotation of the rotating shaft 14, and the tilting rod 16 can laterally support the rotating shaft 14 to increase stress.

[0026] like Figure 4 and Figure 5 As shown, after the support is completed, the scraper blade 4 is not in contact with the side of the coating roller 2. The scraper blade 4 can be moved up to contact the surface of the coating roller 2 by the lifting adjustment component. The lifting adjustment component includes a support cover 7, a reciprocating screw 8, a rotating wheel 10 and a synchronization component. Support covers 7 are fixedly installed on both sides of the coating machine 1. The reciprocating screw 8 is rotatably installed in one of the support covers 7 and a matching crescent slider 9 is installed on the reciprocating screw 8. The rotating wheel 10 is coaxially connected to the reciprocating screw 8. The synchronization component is set in the other support cover 7. The synchronization component includes a synchronization rod 11 and a synchronization block 12. The synchronization rod 11 is fixedly installed in the other support cover 7 and the synchronization block 12 is slidably installed on the synchronization rod 11.

[0027] Specifically, the operator rotates the rotating wheel 10, which drives the reciprocating screw 8 to rotate within one of the support covers 7. This causes the crescent-shaped slider 9 to rise and fall on the reciprocating screw 8. Driven by the connecting plate 13, the synchronous block 12 rises and falls on the synchronous rod 11, which in turn drives the two mounting brackets 6 to move upward synchronously, causing the scraper blade 4 to move upward to the side of the adhesive roller 2. At this point, the rotating wheel 10 stops rotating, and then the lamination process begins. It should be noted that the shape of the crescent-shaped slider 9 matches the spiral groove of the reciprocating screw 8. When the reciprocating screw 8 rotates, the side wall of the spiral groove will generate an axial thrust on the crescent-shaped slider 9 embedded within it. The crescent-shaped slider 9 can move along the axial trajectory of the reciprocating screw 8, thus moving up and down. When the crescent-shaped slider 9 reaches the end of the reciprocating screw 8, it will smoothly transition to the reverse spiral groove, thereby achieving reciprocating movement. This is a well-known technology and will not be elaborated further.

[0028] Working principle: During lamination, two operators first hold two mounting brackets 6 and slide them into the bottom of the mounting rail 5. At this time, the scraper blade 4 is directly below the coating roller 2. Then, the two operators rotate the rotating shaft 14 on the two connecting plates 13, thereby rotating the support rod 15 to the bottom of the mounting bracket 6. After the support rod 15 is rotated below the mounting bracket 6, the mounting bracket 6 is lowered, and the support rod 15 is inserted into the slot of the mounting bracket 6. At this time, the support rod 15 can support the mounting bracket 6, and the mounting bracket 6 can also restrict the rotation of the rotating shaft 14. Finally, the operators rotate the rotating wheel 10, which drives the reciprocating screw 8 to rotate in one of the support covers 7, thereby causing the crescent slider 9 to rise and fall on the reciprocating screw 8. Under the drive of the connecting plate 13, the synchronizing block 12 is driven to rise and fall on the synchronizing rod 11, thereby driving the two mounting brackets 6 to move upward synchronously, so that the scraper blade 4 moves upward to the side of the coating roller 2. At this time, the rotating wheel 10 is stopped.

[0029] After installation, the fabric fibers are wound around the conveyor roller 3. The rotation of the conveyor roller 3 can transport the fabric, and when the fabric moves forward, it will contact the surface of the coating roller 2. The surface of the coating roller 2 is provided with multiple glue outlet holes. A glue storage tank is installed on the side of the device. The side end of the coating roller 2 is designed with a glue inlet connector. The glue storage tank and the coating roller 2 can be connected through the glue delivery pipe, so that the adhesive is delivered to the coating roller 2. After the fabric fibers pass through, the adhesive is applied to it. After the application is completed, because the scraper blade 4 contacts the side of the coating roller 2, it can scrape the outer wall of the coating roller 2, so that the excess adhesive is scraped off, avoiding uneven distribution of adhesive at the glue outlet on the coating roller 2, which would affect subsequent coating.

[0030] It should be added that the mounting components, lifting and adjusting components, and support components are all located in the lower inner part of the glue applicator 1, and in the blank space between the glue applicator roller 2 and the conveying roller 3, so as not to affect the conveying of fabric fibers and the glue application.

[0031] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
