[0001] The utility model relates to the technical field of paper bag bottom pasting machines, in particular to a gluing device for a paper bag bottom pasting machine. Background Technique

[0002] A paper bag bottom pasting machine is a key device for paper bag production, especially playing an important role in the production of kraft paper bags. Its main function is to paste the bottom of the paper bag during the paper bag production process. The machine evenly coats the adhesive on the surface of the paper bag through a series of rollers, and then the paper bag is dried through a drying chamber to ensure that the adhesive can firmly adhere to the paper bag.

[0003] When producing paper bags, it is necessary to apply glue to the paper edges of the paper bags for edge sealing. Some existing paper bag bottom pasting machines cannot control the amount of glue applied to the paper bags during operation, and the paper bags after gluing still need to be folded manually by workers, which not only increases the production cost but also reduces the production efficiency of paper bags. Therefore, a gluing device for a paper bag bottom pasting machine is needed to meet people's needs. Content of the Utility Model

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Embodiment 1: Please refer to Figures 1-4, the utility model provides a technical solution: a glue - applying device for a paper - bag bottom - pasting machine, including a device main body 1 and a conveyor belt 4; one end of the device main body 1 is provided with a glue - applying mechanism 2, and one end of the glue - applying mechanism 2 is provided with an auxiliary mechanism 3; the glue - applying mechanism 2 includes a support frame 21 installed at one end of the conveyor belt 4, one end of the support frame 21 is installed with a glue - applying box 22, one end of the glue - applying box 22 is installed with a glue storage barrel 23, one end of the glue storage barrel 23 is installed with a second motor 24, a feed inlet 25 is opened at the top of the glue storage barrel 23, a stirring blade 26 is installed inside the glue storage barrel 23, a glue outlet 27 is opened inside the glue - applying box 22, one end of the glue outlet 27 is installed with a glue - spraying gun 28, a controller 29 adapted to the glue - spraying gun 28 is installed on the side of the glue - applying box 22, two material - placing plates 5 are installed at one end of the support frame 21, a chute 6 is opened at one end of one material - placing plate 5, symmetric limiting plates 7 are installed on the side of the material - placing plate 5, symmetric limiting blocks 8 are installed at one end of the limiting plates 7, a limiting bolt 9 adapted to the chute 6 is installed on the side of the limiting plate 7, a first motor 10 is installed at one end of the conveyor belt 4, a hot air blower 11 is arranged inside the glue - applying box 22, the hot air blower 11 is adapted to the glue - spraying gun 28, one end of the second motor 24 is connected to the stirring blade 26, a perforation is opened at the bottom of the glue storage barrel 23, and the perforation is communicated with the glue outlet 27. The paper bags to be glued are sorted and placed through the material - placing plates 5. The position of the limiting plates 7 is adjusted according to the size of the paper bags. Rotate the limiting bolt 9 on the side of the limiting plate 7 to make the limiting plate 7 move under the limitation of the limiting block 8. Adjust the positions of the two limiting plates 7, and then tighten the limiting bolt 9 to fix the position of the limiting plate 7. Place the stacked paper bags into the material - placing plates 5. Start the first motor 10 to drive the conveyor belt 4 to rotate and convey the paper bags. At the same time, start the second motor 24 to stir the glue in the glue storage barrel 23. When the paper bags are conveyed into the glue - applying box 22, the glue in the glue storage barrel 23 flows into the glue - spraying gun 28 through the glue outlet 27. The amount of glue ejected by the glue - spraying gun 28 is controlled by the controller 29. When the paper bags are conveyed to the glue - spraying gun 28, the glue - spraying gun 28 applies glue to the paper bags. Through the adjustment of the controller 29, the amount of glue applied is made more accurate, saving production costs. After spraying glue, the hot air blower 11 dries the glue.

[0023] The working principle is as follows: When it is necessary to apply glue to the paper bags, the paper bags to be glued are sorted and placed through the feeding plate 5. The position of the limiting plate 7 is adjusted according to the size of the paper bags. The limiting bolt 9 on the side of the limiting plate 7 is rotated to move the limiting plate 7 under the limitation of the limiting block 8. After adjusting the positions of the two limiting plates 7, the limiting bolt 9 is tightened to fix the position of the limiting plate 7. The stacked paper bags are placed in the feeding plate 5. The first motor 10 is started to drive the conveyor belt 4 to rotate to transport the paper bags. At the same time, the second motor 24 is started to stir the glue in the glue storage barrel 23. When the paper bags are transported into the glue application box 22, the glue in the glue storage barrel 23 flows into the glue spraying gun 28 through the glue outlet 27. The amount of glue sprayed by the glue spraying gun 28 is controlled by the controller 29. When the paper bags are transported to the glue spraying gun 28, the glue spraying gun 28 applies glue to the paper bags. Through the adjustment of the controller 29, the glue application amount is made more accurate, saving the production cost. After spraying glue, the hot air blower 11 dries the glue. When the paper bags continue to be transported to the position of the guiding plate 32, the paper edges of the paper bags are folded inwards through the guiding of the guiding plate 32. The height of the guiding plate 32 can be rotated and adjusted to adapt to the paper edges of different paper bags. After the paper bags pass through the guiding plate 32, the paper edges of the paper bags are further folded by the driving roller 39, making the glue bonding more firm. When the driving roller 39 rolls, the elastic force of the spring 37 makes the driving roller 39 have a certain tension when folding the paper bags, playing a certain protective role on the paper bags and improving the applicability of the device.

[0024] Embodiment 2: As Figure 1 and 4 shown, the auxiliary mechanism 3 includes first fixing blocks 31 symmetrically installed on the side of the support frame 21. One end of the first fixing block 31 is installed with a guiding plate 32. A fixing bolt 33 is installed on the side of the guiding plate 32. One end of the support frame 21 is installed with symmetric second fixing blocks 34. An activity groove 35 is opened in the second fixing block 34. A slider 36 is installed in the activity groove 35. Symmetric springs 37 are installed on the side of the slider 36. One end of the slider 36 is installed with a connecting rod 38. A driving roller 39 adapted to the conveyor belt 4 is installed on the side of the connecting rod 38. The slider 36 is slidably installed in the activity groove 35. One end of the spring 37 is installed on the inner wall of the activity groove 35. The guiding plate 32 is rotatably installed on the side of the first fixing block 31. The fixing bolt 33 passes through the side of the first fixing block 31 and is threadedly connected to the guiding plate 32. When the paper bags are transported to the position of the guiding plate 32, the paper edges of the paper bags are folded inwards through the guiding of the guiding plate 32. The height of the guiding plate 32 can be rotated and adjusted to adapt to the paper edges of different paper bags. After the paper bags pass through the guiding plate 32, the paper edges of the paper bags are further folded by the driving roller 39, making the glue bonding more firm. When the driving roller 39 rolls, the elastic force of the spring 37 makes the driving roller 39 have a certain tension when folding the paper bags, playing a certain protective role on the paper bags and improving the applicability of the device. The other features are the same as those in Embodiment 1.
