[0025] The present invention will be further described below with reference to the accompanying drawings:
[0026] like Figures 1-5 As shown, a composite adhesive application device for packaging bags includes a fixed frame 101, a storage box 102 fixed on the bottom wall of the fixed frame 101, a material pickup groove opened at the upper rear side of the storage box 102, an adhesive roller 302 provided on the material pickup groove, a scraper 405 fixedly connected to the rear end of the material pickup groove, the upper end of the scraper 405 inclined close to the adhesive roller 302, and a stirring mechanism provided inside the storage box 102.
[0027] The mixing mechanism includes a driven shaft 401 and a driving shaft 403, which are rotatably connected inside the storage tank 102. The driven shaft 401 is located below the coating roller 302. Multiple sets of agitating plates are fixedly fixed to the driven shaft 401 along the axial direction. A driven gear 402 is fixedly connected to one end of the driven shaft 401. A driving gear 404 is fixedly mounted on the driving shaft 403 and meshes with the driven gear 402. Multiple tilting plates are fixedly fixed on the driving shaft 403. A drive motor 406 is fixedly connected to one side of the storage tank 102, and the output shaft of the drive motor 406 is fixedly connected to the driving shaft 403. Next, as the coating roller 302 rotates, it picks up the glue through the pick-up trough and scrapes off the excess glue with the scraper 405. Then, the coating roller 302 presses the glue onto the packaging film stably. At the same time, the drive motor 406 is started, which drives the flipping plate through the drive shaft 403 to stir the glue in the storage tank 102. The drive gear 404 meshes with the driven gear 402 to drive the stirring plate to rotate, stirring the glue near the scraper 405 into the storage tank 102. This achieves the reverse rotation of the driven shaft 401 and the drive shaft 403, which stirs the glue in the storage tank 102 evenly and avoids uneven coating caused by glue separation or partial curing.
[0028] The glue-applying roller 302 is rotatably connected between the two side walls of the fixed frame 101. A paint motor 301 is fixedly connected to one side of the fixed frame 101. The output shaft of the paint motor 301 is fixedly connected to the glue-applying roller 302. The paint motor 301 drives the glue-applying roller 302 to rotate.
[0029] A pressure roller 202 is rotatably connected between the two side walls of the fixed frame 101. The pressure roller 202 is located above the glue coating roller 302. A first motor 201 is fixedly installed on one side of the fixed frame 101. The output shaft of the first motor 201 is fixedly connected to the pressure roller 202. The first motor 201 drives the pressure roller 202 to rotate, applying a certain pressure to the packaging film between the glue coating roller 302 and the pressure roller 202, so as to press the glue onto one side of the packaging film.
[0030] A guide roller 501 is provided behind the pressure roller 202. The guide roller 501 is rotatably connected to the fixed frame 101. Both the pressure roller 202 and the guide roller 501 are equipped with pulleys at the end near the drive motor 406. A belt 502 is connected between the two pulleys. The pressure roller 202 drives the guide roller 501 to rotate synchronously through the belt 502.
[0031] A smoothing component is provided on the fixed frame 101. The smoothing component is located at the upper end of the fixed frame 101. The smoothing component includes a conveying roller 601 and a smoothing roller 701. The conveying roller 601 and the smoothing roller 701 are rotatably connected between the two side walls of the fixed frame 101.
[0032] The smoothing roller 701 is located above the conveying roller 601. A power motor 602 is fixedly installed on one side of the fixed frame 101. The output shaft of the power motor 602 is fixedly connected to the conveying roller 601. A first gear 603 is fixed on the side of the conveying roller 601 near the power motor 602.
[0033] A second gear 702 is fixedly connected to one side of the smoothing roller 701. The second gear 702 meshes with the first gear 603. The power motor 602 drives the conveyor roller 601 to rotate. The conveyor roller 601 drives the first gear 603 to mesh with the second gear 702, so that the conveyor roller 601 and the smoothing roller 701 squeeze and smooth the packaging film.
[0034] Working principle: During use, the packaging film is passed between the conveyor roller 601 and the smoothing roller 701, then around the guide roller 501 and through the pressure roller 202 and the coating roller 302. The power motor 602 drives the conveyor roller 601 to rotate, which in turn drives the first gear 603 and the second gear 702 to mesh, causing the conveyor roller 601 and the smoothing roller 701 to press and smooth the packaging film. The coating motor 301 drives the coating roller 302 to rotate. As the coating roller 302 rotates, it picks up glue through the pick-up trough and scrapes off excess glue using the scraper 405. The first motor 201 drives... The rotating pressure roller 202 applies pressure to the packaging film between the coating roller 302 and the pressure roller 202, stably pressing the adhesive onto the packaging film. At the same time, the drive motor 406 is started, which drives the flipping plate through the active rotating shaft 403 to stir the adhesive in the storage tank 102. The active gear 404 meshes with the driven gear 402 to drive the stirring plate to rotate, stirring the adhesive near the scraper 405 into the storage tank 102. This achieves the reverse rotation of the driven rotating shaft 401 and the active rotating shaft 403, making the adhesive in the storage tank 102 evenly stirred, avoiding uneven coating caused by adhesive layering or partial curing.
