Description

Technical Field

[0001] This utility model relates to the field of automobile manufacturing technology, and more specifically, to an automatic airbag processing and production equipment. Background Technology

[0002] An airbag, generally speaking, refers to a flexible container that can rapidly inflate under specific conditions, and it is widely used in many fields. In automobiles, an airbag (also known as a safety airbag) is a passive safety device designed to rapidly inflate in the event of a collision, providing additional protection for passengers. The manufacturing process of airbags is complex and delicate. First, high-strength, high-wear-resistant, and high-heat-resistant fabrics, such as polyamide fibers and polyester fibers, are selected and seamlessly woven. Then, a coating of polyurethane, polyvinyl chloride, or other materials is applied to seal the airbag, improving its waterproof performance and friction resistance, ensuring its stability even in humid environments and reducing injury. Next, the sealed fabric is heated and air-dried, and finally cut, sewn, and sealed. Every step in the entire manufacturing process is crucial, collectively ensuring that the airbag can play its protective role in critical moments.

[0003] However, in actual airbag production, automated coating processes present numerous challenges. The coating process requires precise control of parameters such as coating thickness, uniformity, and curing conditions to ensure coating quality and performance. Existing equipment cannot meet the requirements for precise control of coating thickness and uniformity. Furthermore, issues such as seepage and adhesive overflow during the coating process necessitate additional quality control and repair measures, further increasing production costs and time. Therefore, it is necessary to design an automated airbag manufacturing equipment to address the problems existing in current technologies. Utility Model Content

[0004] The purpose of this utility model is to provide an automated airbag manufacturing equipment to solve the problems mentioned in the background art above:

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An automatic airbag processing production equipment includes an operating table, a conveyor belt rotatably mounted on the operating table, and a coating assembly, a pressure roller, and a scraping assembly sequentially mounted on the operating table. The coating assembly is mounted directly above the conveyor belt at a certain distance, and the scraping assembly and the pressure roller are close to the top of the conveyor belt. The pressure roller is rotatable, and a discharge shaft is installed in front of the conveyor belt, with the discharge shaft corresponding to the position of the conveyor belt.

[0007] By adopting the above technical solution, the material can be moved at a uniform speed using the discharge shaft and the conveyor belt.

[0008] Furthermore, the operating table includes a front support rod at its front end, a recycling trough opened therein, and support blocks and drive seats respectively disposed on both sides of its upper end. The drive seat and the support block are also provided with support plates extending inward. The coating assembly is movably engaged between the support plates, and the discharge shaft is rotatably installed between the front support rods.

[0009] By adopting the above technical solution, the support plate can be used to limit the position of the coating component.

[0010] Furthermore, the coating assembly includes a coating box, limiting slots at both ends of the bottom of the coating box, a connecting block installed on the outside of the coating box, and multiple coating tubes installed downwards at the bottom of the coating box. The coating tubes are arranged at equal intervals and correspond to the top of the conveyor belt. The limiting slots are movably sleeved on the support plate.

[0011] By adopting the above technical solution, the equidistantly arranged coating tubes can uniformly deliver the coating liquid to the fabric surface.

[0012] Furthermore, the scraping assembly includes limiting frames installed on both sides of the operating table, adjusting screws movably passing through the limiting frames, and scrapers installed between the limiting frames. Extension plates are also provided at both ends of the scraper, the extension plates extending into the limiting frames and movably sleeved on the adjusting screws.

[0013] By adopting the above technical solution, the height of the scraper can be adjusted by rotating the adjusting screw, thereby indirectly achieving the adjustment of the coating thickness.

[0014] Furthermore, the operating table also includes a recycling port facing inward, a transfer box located below the recycling port, and a discharge pipe installed at the bottom of the transfer box. The recycling port is located below both sides of the scraping assembly and the pressure roller.

[0015] By adopting the above technical solution, excess coating liquid can be effectively recycled by using the recycling port in conjunction with the transfer box.

[0016] Furthermore, the device also includes a recycling box movably installed in the recycling tank, the recycling box being located directly below the discharge pipe.

[0017] By adopting the above technical solution, the recycled coating liquid can be collected using a recycling box for reuse, thus avoiding resource waste.

[0018] Furthermore, a drive disk can be rotatably mounted on the drive base, an eccentric column is mounted at the eccentric position of the drive disk, a drive motor connected to the drive disk is mounted at the bottom of the drive base, and a follower rod can be rotatably mounted on the eccentric column, with the free end of the follower rod rotatably connected to the connecting block.

[0019] By adopting the above technical solution, the rotation of the drive disk can indirectly drive the coating assembly to make reciprocating displacement movements along the support plate.

[0020] Furthermore, a feeding platform is also provided on the operating table, and a feeding plate is installed on the feeding platform, with the lower end of the feeding plate corresponding to the top of the coating box.

[0021] By adopting the above technical solution, the coating box can be fed in a timely manner using the feeding plate.

[0022] Compared with the prior art, the beneficial effects of this utility model are:

[0023] 1) The device of this application uses a coating component, a pressure roller and a scraping component to coat, squeeze and scrape the fabric in sequence. The coating component makes a reciprocating lateral displacement movement when coating, so that the coating liquid is evenly distributed on the fabric. Then, under the rolling and squeezing of the pressure roller, the coating liquid is further evenly distributed. Finally, the scraping component can scrape the coating to a certain thickness. Moreover, the scraping component is an adjustable design, and the coating thickness can be precisely controlled by controlling the height of the scraper, so as to ensure the coating quality.

[0024] 2) The device of this application adopts a recycling port in conjunction with a transfer box, which can effectively recycle overflow and excess coating material. Under the action of the discharge pipe, the recycled material is concentrated into the recycling box, which effectively realizes the recycling and reuse of coating material and avoids resource waste.

[0032] Please see Figures 1 to 6 An automatic airbag processing production equipment is disclosed, including an operating table 1, a conveyor belt 8 rotatably mounted on the operating table 1, and a coating assembly 4, a pressure roller 6, and a scraping assembly 5 sequentially mounted on the operating table 1. The coating assembly 4 is mounted directly above the conveyor belt 8 at a certain distance, and the scraping assembly 5 and the pressure roller 6 are close to the top of the conveyor belt 8. The pressure roller 6 is rotatable. A discharge shaft 2 is also installed in front of the conveyor belt 8, and the position of the discharge shaft 2 corresponds to that of the conveyor belt 8. The discharge shaft 2 and the conveyor belt 8 can drive the fabric to move at a uniform speed.

[0033] The operating table 1 includes a front support rod 15 at its front end, a recycling trough 11 inside it, and support blocks 12 and drive seats 13 on both sides of its upper end. The drive seat 13 and the support blocks 12 are also provided with support plates 14 extending inward. The coating assembly 4 is movably locked between the support plates 14, and the discharge shaft 2 is rotatably installed between the front support rods 15. The support plates 14 can limit the position of the coating assembly 4.

[0034] The coating assembly 4 includes a coating box 41, limiting slots 43 located at both ends of the bottom of the coating box 41, a connecting block 44 installed on the outside of the coating box 41, and a plurality of coating tubes 42 installed downward inside the bottom of the coating box 41. The coating tubes 42 are arranged at equal intervals and correspond to the top of the conveyor belt 8. The limiting slots 43 are movably sleeved on the support plate 14. The equidistantly arranged coating tubes 42 can evenly deliver the coating liquid to the surface of the fabric.

[0035] The scraping assembly 5 includes a limiting frame 52 installed on both sides of the operating table 1, an adjusting screw 53 movably passing through the limiting frame 52, and a scraper 51 installed between the limiting frames 52. An extension plate 511 is also provided at both ends of the scraper 51. The extension plate 511 extends into the limiting frame 52 and is movably sleeved on the adjusting screw 53. By rotating the adjusting screw 53, the height of the scraper 51 can be adjusted, thereby indirectly realizing the adjustment of the coating thickness.

[0036] The operating table 1 also includes a recovery port 16 facing inward, a transfer box 17 located below the recovery port 16, and a discharge pipe 171 installed at the bottom of the transfer box 17. The recovery port 16 is located below the scraping assembly 5 and the pressure roller 6 on both sides. The recovery port 16, in conjunction with the transfer box 17, can effectively recover excess coating liquid. The equipment also includes a recovery box 9 movably installed in the recovery tank 11, located directly below the discharge pipe 171. The recovery box 9 can be used to collect the recovered coating liquid for reuse, avoiding resource waste. A drive disk 7 is rotatably mounted on the drive base 13. An eccentric column 71 is also mounted at the eccentric position of the drive disk 7. A drive motor 73 connected to the drive disk 7 is also mounted at the bottom of the drive base 13. A follower rod 72 is rotatably mounted on the eccentric column 71. The free end of the follower rod 72 is rotatably connected to the connecting block 44. The rotation of the drive disk 7 can indirectly drive the coating assembly 4 to reciprocate along the support plate 14. The operating table 1 is also equipped with a feeding platform 3, on which a feeding plate 31 is installed. The lower end of the feeding plate 31 corresponds to the top of the coating box 41. The feeding plate 31 can be used to add material to the coating box 41 in a timely manner.

[0037] When implementing the device of this application, the woven fabric roll is first loaded onto the discharge shaft 2. Then, the height of the scraping component 5 is adjusted according to the coating requirements. Specifically, the adjusting screws 53 on both sides are turned, and under the action of the threads, the extension plate 511 moves longitudinally, which in turn drives the scraper 51 to move longitudinally. The adjustable height scraper 51 allows the device of this application to achieve coating processes of different thicknesses, thereby making the device of this application highly practical. After adjustment, the liquid material to be coated is poured onto the feeding plate 31, and the conveyor belt 8 is started and the drive motor 73 is turned on. Under the action of gravity, the coating material slides down into the coating component 4. At the same time, the drive motor 73 drives the drive disk 7 to rotate, the eccentric column 71 makes a circular motion, and drives the coating component 4 along the support plate 14 through the follower rod 72. The fabric moves back and forth; simultaneously, the fabric on the discharge shaft 2 contacts the conveyor belt 8 and moves under the drive of the conveyor belt 8. When the fabric moves directly below the coating tube 42, the coating material in the coating assembly 4 falls onto the displaced fabric through the coating tube 42. The equidistantly arranged coating tubes 42, together with the left and right reciprocating coating assembly 4, can ensure that the fabric is coated in place. The fabric coated with the coating material continues to move forward. When it passes the pressure roller 6, the coating material accumulated on it is squeezed by the rotating pressure roller 6, and at the same time, the coating liquid is evenly coated on the fabric. Then, the fabric continues to move forward. When it moves to below the scraper 51, the coating material on it is scraped to a certain thickness under the limit of the scraper 51. Finally, the fabric coating is completed and it separates from the conveyor belt 8 from the tail end of the conveyor belt 8 for the next process. During processing, excess coating liquid is generated and overflows due to the squeezing of the pressure roller 6 and the scraping of the scraper 51. The excess coating liquid flows from the recovery ports 16 on both sides of the conveyor belt 8 into the transfer box 17, and then flows into the recycling box 9 through the discharge pipe 171 at the bottom of the transfer box 17, thereby achieving effective recovery and reuse of the coating liquid. This ensures coating quality while avoiding resource waste. In addition, the drive motor 73 and conveyor belt 8 used in the device of this application are existing technologies, and their specific working principles will not be elaborated in this technical solution.
