Description

Technical Field

[0001] The utility model belongs to the technical field of paper bag making, in particular to a paper bag gluing device. Background Art

[0002] Paper bags are widely used in daily life, including kraft paper bags, white paper tapes and copper paper tapes. At present, paper bags need to be glued together during the production process. At this time, a paper bag gluing device is needed to glue the paper bags.

[0003] When gluing paper bags, the existing paper bag gluing device first places the paper bag on the gluing device to check whether the surface of the paper bag is flat and clean, then turns on the gluing machine to apply glue on the surface of the paper bag, and then glues the paper bags together and places them in a ventilated place to wait for the glue to solidify. During long-term use and observation, it is found that the existing paper bag gluing device applies glue to the edges of the paper bag separately when applying glue, which leads to uneven glue application due to different glue output amounts and the need to adjust the position of the paper bag for multiple times for gluing.

[0004] To this end, the utility model provides a paper bag gluing device. Utility Model Content

After the gluing of the paper bags is completed, there will be residual glue on the surface of the operating table, which will affect the subsequent gluing of the paper bags. At this time, the scraper can scrape off the residual glue to reduce the influence of the residual glue on the subsequent paper bags.

[0010] Preferably, a hot air blower is fixedly connected to the middle of the first fixed frame; an air outlet duct is fixedly connected to the bottom of the hot air blower; the air outlet duct is arranged toward the top of the operating table; in this step, by arranging the hot air blower and the air outlet duct, hot air can be blown to the paper bag to make the glue on the paper bag solidify faster; after the paper bag is glued, the paper bag is placed on the surface of the operating table below the air outlet duct, and the hot air at the air outlet duct is blown to the surface of the paper bag to accelerate the solidification of the glue, so as to reduce the uneven glue caused by the flow of glue when it is not dry, and the uniformity of glue coating can be improved.

Then the first electric push rod 12 is started to extend the first electric push rod 12 to drive the first glue hose 13 and the third glue hose 16 to approach the paper bag. When the glue nozzle 17 contacts the paper bag, the paper bag can be glued. This step can complete the gluing of the paper bag at one time by setting the first glue hose 13 and the third glue hose 16. When gluing the paper bag, the first glue hose 13 and a pair of third glue hoses 16 can fit the shape of the paper bag. At this time, glue can be injected into the edge of the paper bag at the same time without moving the position of the paper bag, and there is no need to glue each side of the paper bag separately, which reduces the situation of glue flow caused by the movement of the paper bag and makes the gluing more uniform. When the width of the paper bag is different, the second glue hose 14 can be drawn out of the first glue hose 13 to make the third glue hose 16 overlap with the edge of the paper bag to adapt to paper bags of different widths and improve the utilization rate of the overall structure.

[0025] like Figure 4As shown, a pair of second fixed frames 2 are fixedly connected to the side wall of the first rubber tube 13; a plurality of scrapers 21 are fixedly connected to the inner side walls of the pair of second fixed frames 2; the scrapers 21 are in contact with the side wall of the second rubber tube 14; during operation, when the second rubber tube 14 is drawn out or retracted from the first rubber tube 13, the scrapers 21 will slide on the surface of the second rubber tube 14. In this step, the second fixed frame 2 and the scrapers 21 are arranged to scrape the side wall of the second rubber tube 14 to scrape off the glue attached to the side wall of the second rubber tube 14. When the second rubber tube 14 is retracted into the first rubber tube 13, the glue on the side wall of the second rubber tube 14 will agglomerate due to air drying. At this time, the scrapers 21 scrape the side wall of the second rubber tube 14 to reduce the agglomerated glue attached to the side wall of the second rubber tube 14, and reduce the agglomerated glue from entering the first rubber tube 13 to cause the glue nozzle 17 to be blocked.

[0026] like Figure 3 As shown, the side wall of the first rubber hose 13 is fixedly connected to a fixing plate 3; the bottom of the fixing plate 3 is fixedly connected to a spring rod 31; the end of the spring rod 31 is fixedly connected to a pressing plate 32; during operation, when the first electric push rod 12 drives the first rubber hose 13 to move toward the paper bag, the first rubber hose 13 can drive the spring rod 31 and the pressing plate 32 to move toward the paper bag, and when the pressing plate 32 contacts the paper bag, the spring rod 31 will be squeezed and contracted, and at this time the glue nozzle 17 will contact the paper bag for glue coating. In this step, the paper bag can be fixed by setting the spring rod 31 and the pressing plate 32. When gluing the paper bag, the pressing plate 32 will contact the paper bag before the glue nozzle 17 contacts the paper bag. At this time, the pressing plate 32 will squeeze the spring rod 31 to contract so that the glue nozzle 17 contacts the paper bag. At this time, the pressing plate 32 will press the paper bag to fix the position of the paper bag, which can improve the uniformity of glue coating.

[0027] like Figure 1 As shown, the inner wall of the operating table 1 is fixedly connected to a second electric push rod 4; the end of the second electric push rod 4 is fixedly connected to a scraper 41; the bottom of the scraper 41 contacts the top of the operating table 1; the inner wall of the operating table 1 is provided with a pair of slide grooves 43; the middle parts of the pair of slide grooves 43 are slidably connected to a slider 42; the side wall of the slider 42 is fixedly connected to the scraper 41; during operation, when the paper bag is glued, the second electric push rod 4 is started to extend to drive the scraper 41 to slide on the surface of the operating table 1, and the surface of the operating table 1 can be scraped. In this step, the second electric push rod 4 is set to drive the scraper 41 to slide, so as to scrape the surface of the operating table 1. When the paper bag is glued, there will be residual glue on the surface of the operating table 1, which will affect the subsequent gluing of the paper bag. At this time, the scraper 41 can scrape off the residual glue to reduce the influence of the residual glue on the subsequent paper bags.

[0028] like Figure 2As shown, a hot air blower 5 is fixedly connected to the middle of the first fixed frame 11; an air outlet pipe 51 is fixedly connected to the bottom of the hot air blower 5; the air outlet pipe 51 is arranged toward the top of the operating table 1; during operation, after the paper bag is coated with glue, the paper bag is placed near the air outlet pipe 51, and the hot air blower 5 is started at this time to generate hot air that is blown to the surface of the paper bag through the air outlet pipe 51. In this step, the hot air blower 5 and the air outlet pipe 51 are arranged to blow hot air to the paper bag so that the glue on the paper bag solidifies faster. After the paper bag is coated with glue, the paper bag is placed on the surface of the operating table 1 below the air outlet pipe 51, so that the hot air at the air outlet pipe 51 is blown to the surface of the paper bag to accelerate the solidification of the glue, so as to reduce the situation where the glue flows when it is not dry and causes uneven glue, and the uniformity of glue coating can be improved.

[0029] like Figure 2 As shown, the side wall of the air outlet pipe 51 is fixedly connected with an air hood 6; a plurality of air outlet holes 61 are provided at the bottom of the air hood 6; the air outlet holes 61 are arranged toward the top of the operating table 1; during operation, when the hot air blower 5 blows air to the paper bag, the hot air will flow into the air hood 6 from the air outlet pipe 51 and then be blown onto the paper bag from the air outlet holes 61. This step can increase the range of the hot air by arranging the air hood 6 and the air outlet holes 61, so that the contact surface between the hot air and the paper bag is larger. When the hot air in the air outlet pipe 51 blows toward the paper bag, the air hood 6 can change the range of the hot air, so that the hot air blown to the paper bag is wider and can completely cover the glue, so that the glue can solidify more evenly.

[0030] like Figure 2 As shown, a collecting groove 72 is provided in the middle of the operating table 1; a third fixed frame 7 is fixedly connected to the bottom of the operating table 1; a collecting box 71 is provided on the inner wall of the third fixed frame 7; the collecting box 71 is slidably matched with the third fixed frame 7; during operation, when the scraper 41 scrapes the surface of the operating table 1, the glue remaining on the surface of the operating table 1 will be pushed to the collecting groove 72 by the scraper 41, and then fall from the collecting groove 72 into the collecting box 71 below. In this step, the glue remaining on the surface of the operating table 1 can be collected by setting the collecting box 71 and the collecting groove 72. When the scraper 41 scrapes the surface of the operating table 1, the remaining glue falls into the collecting box 71 through the collecting groove 72, so as to reduce the influence of the glue remaining on the surface of the operating table 1 on the subsequent gluing of paper bags.

[0031] Working principle: When gluing a paper bag, place the paper bag on the top of the operating table 1, connect the glue to the glue hose 19, and then start the first electric push rod 12 to extend the first electric push rod 12 to drive the first glue hose 13 and the third glue hose 16 to approach the paper bag. When the glue nozzle 17 contacts the paper bag, the gluing of the paper bag can be completed. When the second glue hose 14 is pulled out or retracted from the first glue hose 13, the scraper 21 will slide on the surface of the second glue hose 14. When the first electric push rod 12 drives the first glue hose 13 to move toward the paper bag, the first glue hose 13 can drive the spring rod 31 and the pressure plate 32 to move toward the paper bag. When the pressure plate 32 contacts the paper bag, the spring rod 31 will be squeezed and contracted, and the glue nozzle 17 will Contact with the paper bag for gluing. After the gluing of the paper bag is completed, start the second electric push rod 4 to extend to drive the scraper 41 to slide on the surface of the operating table 1, and scrape the surface of the operating table 1. When the gluing of the paper bag is completed, place the paper bag near the air outlet pipe 51. At this time, start the hot air blower 5 to generate hot air that is blown to the surface of the paper bag through the air outlet pipe 51. When the hot air blower 5 blows air to the paper bag, the hot air will flow into the wind cover 6 from the air outlet pipe 51 and then be blown out from the air outlet hole 61 onto the paper bag. When the scraper 41 scrapes the surface of the operating table 1, the glue remaining on the surface of the operating table 1 will be pushed to the collection tank 72 by the scraper 41, and then fall from the collection tank 72 into the collection box 71 below.
