Description

Technical Field

[0001] This invention relates to the field of auxiliary equipment technology for airbag production, and in particular to an airbag fabric coating device. Background Technology

[0002] With the development of highways and the improvement of automobile performance, the speed of cars is getting faster and faster. In particular, due to the rapid increase in the number of cars, traffic is becoming more and more congested, making accidents more frequent. Therefore, the safety of cars has become particularly important. As we all know, airbags are very effective in cushioning impacts. They can fully absorb part of the impact force on the driver and passengers, and assist seat belts in protecting them. During the production process, airbag fabric needs to be coated with adhesive to increase the elasticity of the airbag and make it resistant to high temperatures and moisture.

[0003] Traditionally, the application of adhesive to airbag fabrics is mostly done manually. This method is not only slow, but also results in uneven adhesive thickness and consumes a lot of manpower and resources. Existing adhesive application equipment cannot dry the airbag fabrics in time after application, which affects the quality of the adhesive application.

[0004] Therefore, there is an urgent need to provide a device for applying adhesive to airbag fabric to solve the above problems. Summary of the Invention

[0005] The technical problem to be solved by this invention is that traditionally, the coating of airbag fabric is mostly done manually. This method is not only slow, but also results in uneven coating thickness and consumes a lot of manpower and resources. Furthermore, existing coating devices cannot dry the airbag fabric in time after coating, which affects the coating quality.

[0006] To solve the above-mentioned technical problems, the present invention provides a device for applying adhesive to airbag fabric, comprising a worktable, two first support plates fixedly connected to one side of the worktable, two guide rollers rotatably connected between the two first support plates, an adhesive dispensing mechanism provided at the top of the worktable, and an adhesive leveling mechanism provided on the other side of the top of the worktable near the adhesive dispensing mechanism; a first concave frame fixedly connected to the top of the worktable, a fan fixedly connected to the top of the first concave frame, a first connecting pipe fixedly connected to the rear end of the fan, a heating box fixedly connected to the rear end of the first connecting pipe, a second connecting pipe fixedly connected to the rear end of the heating box, an air hood fixedly connected to the bottom of the second connecting pipe; two second support plates fixedly connected to the other side of the worktable, two receiving rollers rotatably connected between the two second support plates, and two drive motors corresponding to the receiving rollers fixedly connected to the front end of one of the second support plates; and multiple support columns fixedly connected to the bottom of the worktable.

[0007] The glue dispensing mechanism includes two third support plates fixedly connected to the top of the workbench, a glue storage tank fixedly connected between the two third support plates, a glue addition pipe fixedly connected to the top of the glue storage tank, a glue dispensing trough fixedly connected to the bottom of the glue storage tank, and a glue dispensing roller horizontally rotatably connected to the bottom of the glue storage tank.

[0008] The above technical solution involves adding glue into the glue storage tank, causing two drive motors to rotate in opposite directions, which in turn causes two take-up rollers to rotate and move the airbag fabric. The glue dispensing roller rotates to apply the glue from the glue storage tank to the surface of the airbag fabric.

[0009] A sponge layer is fixedly connected to the outer wall of the dispensing roller.

[0010] By using the above technical solution, the dispensing speed of the dispensing trough is controlled, making the dispensing of glue from the dispensing roller more uniform.

[0011] The coating mechanism includes a second concave frame fixedly connected to the top of the workbench. A threaded rod is rotatably connected to the top of the second concave frame. A handle is fixedly connected to the top of the threaded rod. A scraper is fixedly connected to the bottom of the threaded rod. Limiting sliders are fixedly connected to both the front and rear ends of the scraper.

[0012] The above technical solution involves rotating the handle to move the threaded rod downwards, thereby moving the scraper to a suitable height. The scraper then smooths the adhesive on the surface of the airbag fabric after coating, improving the coating quality.

[0013] The inner walls of the front and rear ends of the second concave frame are provided with limiting grooves corresponding to the limiting sliders.

[0014] The above technical solution limits and guides the movement of the limiting slider, ensuring that the scraper moves stably in the vertical direction.

[0015] The air outlet hood extends through the top of the first concave frame.

[0016] Through the above technical solution, the air blown out by the fan is heated by the heating box and then blown onto the surface of the airbag fabric after the glue has been applied by the air outlet hood, which dries the glue in time and greatly improves the glue application efficiency.

[0017] The two drive motors rotate in opposite directions.

[0018] The above technical solution ensures that the two drive motors drive the two take-up rollers to rotate in opposite directions, thereby providing power for the movement of the airbag fabric between the two take-up rollers.

[0019] The beneficial effects of this invention are as follows:

[0020] 1. This invention designs a glue dispensing mechanism and a glue spreading mechanism that work together. Two drive motors are turned on and rotate in opposite directions, which causes two take-up rollers to rotate and move the airbag fabric. The glue dispensing roller rotates and applies the glue in the glue storage tank to the surface of the airbag fabric. At the same time, the scraper smooths the glue on the surface of the airbag fabric after it has been glued, thus improving the glue coating quality.

[0021] 2. This invention designs a fan and a heating box that work together. The air blown out by the fan is heated by the heating box and then blown onto the surface of the coated airbag fabric by the air outlet hood, which dries the adhesive in time and greatly improves the coating efficiency.

[0028] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more explicit definition of the scope of protection of the present invention.

[0029] Please see Figures 1-2This airbag fabric coating device includes a workbench 1. Two first support plates 2 are fixedly connected to one side of the workbench 1, and two guide rollers 3 are rotatably connected between the two first support plates 2. A glue dispensing mechanism 4 is provided on the top of the workbench 1, and a glue evenly dispensing mechanism 5 is provided on the other side of the top of the workbench 1 near the glue dispensing mechanism 4. A first concave frame 6 is fixedly connected to the top of the first concave frame 6, and a fan 7 is fixedly connected to the top of the fan 7. A first connecting pipe 8 is fixedly connected to the rear end of the fan 7, and a heating box 9 is fixedly connected to the rear end of the first connecting pipe 8. A second connecting pipe 10 is fixedly connected to the rear end of the heating box 9, and an air outlet hood 11 is fixedly connected to the bottom of the second connecting pipe 10, and the air outlet hood 11 penetrates the first concave frame 6. At the top, the air blown by the fan 7 is heated by the heating box 9 and blown onto the surface of the airbag fabric after being coated with glue by the air outlet hood 11, which dries the glue in time and greatly improves the glue coating efficiency. Two second support plates 12 are fixedly connected to the other side of the workbench 1. Two take-up rollers 13 are rotatably connected between the two second support plates 12. Two drive motors 14 corresponding to the take-up rollers 13 are fixedly connected to the front end of one of the second support plates 12. The two drive motors 14 rotate in opposite directions, ensuring that the two drive motors 14 drive the two take-up rollers 13 to rotate in opposite directions, thereby providing power for the movement of the airbag fabric between the two take-up rollers 13. Multiple support columns 15 are fixedly connected to the bottom of the workbench 1.

[0030] like Figure 3 and Figure 5As shown, the glue dispensing mechanism 4 includes two third support plates 401 fixedly connected to the top of the workbench 1. A glue storage tank 402 is fixedly connected between the two third support plates 401. A glue adding pipe 403 is fixedly connected to the top of the glue storage tank 402. A glue dispensing trough 404 is fixedly connected to the bottom of the glue storage tank 402. A glue dispensing roller 405 is horizontally rotatably connected to the bottom of the glue storage tank 402. A sponge layer is fixedly connected to the outer wall of the glue dispensing roller 405 to control the glue dispensing speed of the glue dispensing trough 404, so that the glue dispensing roller 405... To ensure more even glue distribution, glue is added to the glue storage tank 402. Two drive motors 14 rotate in opposite directions, causing the two take-up rollers 13 to rotate and move the airbag fabric. The glue dispensing roller 405 rotates, spreading the glue from the storage tank 402 onto the surface of the airbag fabric. Specifically, one end of the glue dispensing roller 405 is connected to a power motor 407 that enables rotation, and the other end is connected to one end of the drive arm 408. A guide seat 41 is vertically fixed to the inner wall of the top of the glue storage tank 402. 1. The guide seat 411 is located directly below the glue addition tube 403. The guide seat 411 and the straight part 409b of the guide rod of the linkage 409 are slidably connected. An adjustment shaft 412 that cooperates with the glue addition tube 403 is also installed on the straight part 409b of the guide rod. The adjustment shaft 412 can be in a sealed sliding fit with the glue addition tube 403. A sliding seat 413 is slidably connected inside the arc-shaped part 409a of the guide rod of the linkage 409. The sliding seat 413 is rotatably connected to the other end of the drive arm 408. An auxiliary stirring plate 410 is also installed on the seat 413, and a replenishment box 406 is connected to the glue addition pipe 403. The control shaft 412 also has a notch 412a. With this structure, when the glue dispensing roller 405 is working, the straight part 409b of the guide rod can move up and down repeatedly, so that the glue in the replenishment box 406 can be automatically replenished into the glue storage box 402. At the same time, the auxiliary stirring plate 410 can assist in stirring the glue replenished into the glue storage box 402, so that it is more evenly distributed.

[0031] like Figure 4 As shown, the glue-applying mechanism 5 includes a second concave frame 501 fixedly connected to the top of the workbench 1. A threaded rod 502 is rotatably connected to the top of the second concave frame 501. A handle 503 is fixedly connected to the top of the threaded rod 502. A scraper 504 is fixedly connected to the bottom of the threaded rod 502. Limiting sliders 505 are fixedly connected to both the front and rear ends of the scraper 504. Limiting grooves corresponding to the limiting sliders 505 are opened on the inner walls of both the front and rear ends of the second concave frame 501, which limit and guide the movement of the limiting sliders 505, so that the movement of the scraper 504 in the vertical direction remains stable. Rotating the handle 503 drives the threaded rod 502 to move downward, thereby moving the scraper 504 to a suitable height. The scraper 504 smooths the glue on the surface of the airbag fabric after glue application, improving the glue application quality.

[0032] In use, the airbag fabric to be coated with adhesive is passed through two guide rollers 3 and two take-up rollers 13. Two drive motors 14 are turned on to ensure that the two drive motors 14 drive the two take-up rollers 13 to rotate in opposite directions, providing power for the movement of the airbag fabric between the two take-up rollers 13. The glue dispensing roller 405 rotates to apply the glue in the glue storage tank 402 to the surface of the airbag fabric. The handle 503 is turned to drive the threaded rod 502 to move downward, so that the scraper 504 moves to a suitable height. The scraper 504 scrapes the glue on the surface of the airbag fabric after coating, improving the coating quality. Then, the fan 7 and the heating box 9 are turned on. The air blown by the fan 7 is heated by the heating box 9 and blown onto the surface of the coated airbag fabric by the air outlet hood 11, which dries the glue in time and greatly improves the coating efficiency.
