The adhesive coating and bonding equipment is mainly used to achieve precise adhesive coating and bonding between the base fabric and the protective layer, and is suitable for large-scale production needs.

[0003] For example, the utility model application with application number CN210647082 discloses an automated glue coating equipment. Similar automated glue coating equipment currently has the following shortcomings: During the glue coating process, although it can apply glue evenly to the surface of the workpiece, the single even glue structure makes the glue flow generally weak, which is not conducive to fully improving the uniformity of glue coating. Summary of the Invention

[0004] The purpose of this invention is to provide an adhesive bonding device for airbag base fabric composite processing, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adhesive bonding device for airbag base fabric composite processing, comprising a worktable, an adhesive application assembly, and a hot air jet assembly. An upper frame is fixed to the upper rear side of the worktable, and the adhesive application assembly is fixed to the lower side of the upper frame. An electric telescopic rod is installed on the lower right side of the upper frame, and a lifting plate is fixed to the bottom of the electric telescopic rod. A flat adhesive plate is connected to the lower side of the lifting plate. A hot air jet assembly is installed on the upper side of the lifting plate, and the hot air jet assembly includes a hot air box, a heating layer, a jet box, a jet nozzle, and a filter. A heating layer is provided on the lower inner side of the hot air box, and a jet box is fixed to the outer side of the hot air box.

[0006] The adhesive application assembly includes a guide rail and a movable seat. The guide rail is fixedly connected to the upper frame, and the movable seat is slidably mounted on the outer side of the guide rail.

[0007] The adhesive application assembly also includes an electric lifting rod and an adhesive collection pipe. The electric lifting rod is installed on the lower side of the movable seat, and the adhesive collection pipe is fixed to the bottom of the electric lifting rod.

[0008] The adhesive application assembly also includes a feeding pipe, a control valve, and an adhesive application head. The feeding pipe is connected at equal intervals to the lower side of the adhesive collection pipe, and the control valve is installed in the middle of the feeding pipe. The adhesive application head is fixed at the bottom of the feeding pipe.

[0009] A glue tank is fixed to the upper middle part of the upper frame, and a flexible glue delivery pipe is connected between the lower side of the glue tank and the glue collection pipe.

[0010] The hot air jet assembly also includes an intake fan, an air pump, and an air delivery pipe.

[0014] This utility model is equipped with a hot air jet assembly. The heating layer on the lower side of the hot air box facilitates the heating of the air inside. The hot air is delivered into the air jet box through the air pump and air delivery pipe, so that the air jet nozzle on the lower side of the air jet box sprays hot air onto the surface of the glued airbag base fabric.

Detailed Implementation

[0017] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0018] like Figure 1 and Figure 4 As shown, an adhesive bonding device for airbag base fabric composite processing includes a worktable 1, an adhesive application assembly 3, and a hot air jet assembly 9. An upper frame 2 is fixed to the upper rear side of the worktable 1, and the adhesive application assembly 3 is fixed to the lower side of the upper frame 2. The adhesive application assembly 3 includes a guide rail 301 and a movable seat 302. The guide rail 301 is fixedly connected to the upper frame 2, and the movable seat 302 is slidably mounted on the outer side of the guide rail 301. The adhesive application assembly 3 also includes an electric lifting rod 303 and an adhesive collection pipe 304. The electric lifting rod 303 is mounted on the lower side of the movable seat 302, and the adhesive collection pipe 304 is fixed to the bottom of the electric lifting rod 303. The adhesive application assembly 3 also includes a feeding pipe 305, a control valve 306, and an adhesive application head 307. The feeding pipe 305 is equidistantly connected to the lower side of the adhesive collection pipe 304, and the feeding pipe 305... A control valve 306 is installed in the middle, and a glue applicator 307 is fixed at the bottom of the feed pipe 305. A glue tank 4 is fixed on the upper side of the middle part of the upper frame 2, and a flexible glue delivery pipe 5 is connected between the lower side of the glue tank 4 and the glue collection pipe 304. The extension and retraction of the electric lifting rod 303 facilitates the adjustment of the glue application height of the glue collection pipe 304 and the glue applicator 307. The glue can be pumped into the glue collection pipe 304 through the glue delivery pipe 5. The glue can be applied evenly through the uniformly distributed feed pipe 305 and glue applicator 307. The glue applicator 307 can be selected according to the width of the airbag base fabric. The control valve 306 at the feed pipe 305 is closed when the glue applicator 307 is not in use. The movement of the movable seat 302 on the guide rail 301 facilitates the movement of the glue collection pipe 304 and the glue applicator 307 for glue application.

[0019] like Figure 1 and Figure 3As shown, an electric telescopic rod 6 is installed on the lower right side of the upper frame 2, and a lifting plate 7 is fixed to the bottom of the electric telescopic rod 6. A flat rubber plate 8 is connected to the lower side of the lifting plate 7. Two mounting plates 10 are bolted to the outer sides of the upper frame 2, and a guide roller 11 is rotatably mounted on one side of the mounting plate 10 via a rotating shaft. The two guide rollers 11 are parallel to each other, and a scraper 12 is fixed to one side of one of the mounting plates 10. The extension and retraction of the electric telescopic rod 6 facilitates the lifting and retraction of the lifting plate 7, so that the flat rubber plate 8 is located on the upper side of the adhesive on the surface of the airbag base fabric. Then, the surface of the airbag base fabric after gluing is treated with a smoothing process to maintain the relative uniformity of the adhesive layer thickness on the surface of the airbag base fabric. The two sets of guide rollers 11 on both sides of the worktable 1 are used to assist in the traction and feeding of the airbag base fabric. A corresponding drive motor is installed on one end of the rotating shaft of the guide roller 11 outside the mounting plate 10. The scraper 12 is located on the side of the guide roller 11 on the upper right side. When the airbag base fabric moves from left to right, the guide roller 11 can rotate to further promote the uniform coating of the adhesive. The scraper 12 can scrape off the excess adhesive on the surface of the guide roller 11. The surface of the scraper 12 can be cleaned periodically.

[0020] like Figures 1-3 As shown, a hot air jet assembly 9 is installed on the upper side of the lifting plate 7. The hot air jet assembly 9 includes a hot air box 901, a heating layer 902, a jet box 903, a jet nozzle 904, and a filter screen 905. The heating layer 902 is provided on the lower inner side of the hot air box 901, and the jet box 903 is fixed on the outer side of the hot air box 901. The jet nozzle 904 is connected to the lower side of the jet box 903, and a filter screen 905 is fixed between the jet box 903 and the jet nozzle 904. The jet nozzle 904 has an inclined elongated structure. The hot air jet assembly 9 also includes an intake fan 906, an air pump 907, and an air delivery pipe 908. The intake fan 906 is installed on the side of the hot air box 901, and a filter screen 905 is installed on the upper side of the hot air box 901. An air pump 907 is provided, and an air supply pipe 908 is connected to one side of the air pump 907. The air supply pipe 908 is connected to the air jet box 903. The heating layer 902 on the lower side of the hot air box 901 facilitates the heating of the air inside. The air pump 907 and the air supply pipe 908 facilitate the delivery of hot air into the interior of the air jet box 903, so that the air jet nozzle 904 on the lower side of the air jet box 903 sprays hot air onto the surface of the glued airbag base fabric. The air jet nozzle 904 sprays intermittently and has an inclined structure to avoid the airflow directly blowing and disturbing the adhesive. At the same time, the air blowing area is wider, so that the surface of the glued airbag base fabric can be heated evenly and the adhesive can have higher fluidity, which is convenient for use with the flat adhesive board 8.

[0021] In summary, as Figures 1-4As shown, the gluing and bonding equipment for airbag base fabric composite processing can first feed the airbag base fabric using the feeding mechanisms on both sides of the worktable 1. At this time, the two sets of guide rollers 11 on both sides of the worktable 1 are used to assist in the traction and feeding of the airbag base fabric. Then, the gluing height of the glue collection pipe 304 and the glue application head 307 can be adjusted by the extension and retraction of the electric lifting rod 303. Then, the glue is pumped into the glue collection pipe 304 through the glue delivery pipe 5. Then, the glue is applied evenly through the uniformly distributed feeding pipe 305 and the glue application head 307. The glue application head 307 can be selected according to the width of the airbag base fabric. The control valve 306 at the feeding pipe 305 is closed when the glue application head 307 is not used. The movement of the movable seat 302 on the guide rail 301 can also facilitate the movement of the glue collection pipe 304 and the glue application head 307 for gluing. Then the airbag base fabric moves from left to right. During this process, the heating layer 902 on the lower side of the hot air box 901 heats the air inside. Then, the hot air is sent into the air jet box 903 through the air pump 907 and the air pipe 908. This causes the air jet nozzle 904 on the lower side of the air jet box 903 to spray hot air onto the surface of the glued airbag base fabric. The air jet nozzle 904 sprays intermittently and has an inclined structure to avoid the airflow from directly blowing and disturbing the adhesive. At the same time, the blowing area is wider, so that the surface of the glued airbag base fabric can be heated evenly and the adhesive can have higher fluidity, which is convenient for use with the flat adhesive plate 8. At this time, the lifting plate 7 can be raised and lowered by the extension and retraction of the electric telescopic rod 6, so that the flat adhesive plate 8 is located on the upper side of the adhesive on the surface of the airbag base fabric, thereby performing a flat adhesive treatment on the surface of the airbag base fabric after adhesive application, maintaining the relative uniformity of the adhesive layer thickness on the surface of the airbag base fabric. The scraper 12 is located on the side of a guide roller 11 on the upper right side. When the airbag base fabric moves from left to right, the guide roller 11 can rotate to further promote the uniform coating of adhesive, while the scraper 12 can scrape off excess adhesive on the surface of the guide roller 11. The surface of the scraper 12 can be cleaned periodically. This completes the use process of the adhesive coating and bonding equipment for airbag base fabric composite processing.
