[0002] When processing packaging boxes, you need to use a folder gluer. The application of the folder gluer is the last step in the processing of packaging boxes. It is to fold the printed and die-cut cardboard into shape and glue the edges. The machine glues the box instead of the manual box gluer, which reduces labor costs and improves efficiency. During use, the folder gluer will perform operations such as paper feeding, pre-folding, bottom hooking, forming, gluing, and pressing on the pre-cut cardboard.

[0003] In the related art, a Chinese patent with publication number CN209208145U proposes an automatic box gluing machine for packaging boxes, which can complete the box gluing process on the cardboard in the box sheet library through a pushing device, a traction speed regulating device, a creasing mechanism, a gluing device, a box folding device and an output mechanism.

[0004] The above-mentioned related technologies have the following defects: the glue paste is easy to condense into blocks in the barrel of the paste due to low temperature or long time without flowing. In addition, the glue remaining and agglomerated in the barrel of the paste is not easy to clean because the barrel is closed. Utility Model Content

The containing component 51 may store glue and be used to glue the paper box. The opening and closing motor 53 is fixedly mounted on the outside of the containing component 51, and the output end of the opening and closing motor 53 is driven to connect the cover closing component 52, so that the cover closing component 52 is movably arranged above the containing component 51, and is used to close or open the containing component 51.

[0024] See also Figure 2 The holding assembly 51 may include a glue barrel 510, an output pipe 511, a bottom bracket 512, an agitating motor 513, an agitating member 514, at least one set of scrapers 515, and a side bracket 516. An opening is formed at the upper end of the glue barrel 510, and colloid can be poured into the glue barrel 510 or the glue barrel 510 can be cleaned from the upper end opening of the glue barrel 510. The output pipe 511 is connected to the lower end of the glue barrel 510, and a solenoid valve is installed on the output pipe 511. The output pipe 511 is used to output colloid when pasting boxes. The bottom bracket 512 is welded and fixed to the lower end of the glue barrel 510, the agitating motor 513 is installed and fixed on the bottom bracket 512, and the lower end of the output pipe 511 can pass through the bottom bracket 512. The output end of the stirring motor 513 extends into the glue barrel 510 and is fixedly connected to the lower end of the stirring member 514, so that the stirring member 514 is rotatably arranged in the inner cavity of the glue barrel 510, and the coagulation of the colloid caused by not flowing for a long time can be reduced. The middle part of the stirring member 514 can be formed with a plurality of hollow grooves, so that when it is rotated and stirred, the colloid can be not separated and can flow evenly. At least one group of scrapers 515 is fixedly connected to the outside of the stirring member 514, the height of the scraper 515 is adapted to the height of the inner cavity of the glue barrel 510, and the outer wall of the scraper 515 is in contact with the inner wall of the glue barrel 510, so that the scraper 515 can scrape off the colloid attached to the inner wall of the glue barrel 510 when the stirring member 514 rotates. The outer wall of the scraper 515 can be coated with a rubber protective layer to reduce the scratches of the scraper 515 on the glue barrel 510. The side bracket 516 is welded and fixed to the upper end of the outer wall of the rubber barrel 510 , and the opening and closing motor 53 is installed and fixed on the side bracket 516 .

[0026] See also Figure 3 The cover assembly 52 may include a barrel cover 520, two sets of hanging frames 521, a lower end plug shaft 522, an upper end plug shaft 523, a driving arm 524 and a supporting arm 525. In normal use, the barrel cover 520 is arranged at the upper end of the containing assembly 51 in cooperation with the containing assembly 51. The two sets of hanging frames 521 are symmetrically fixed to the top of the barrel cover 520 by bolts, and the upper end plug shaft 523 and the lower end plug shaft 522 are sequentially inserted between the two sets of hanging frames 521 from top to bottom and fixedly connected thereto. One end of the driving arm 524 is fixedly connected to the output end of the opening and closing motor 53, and the other end of the driving arm 524 is sleeved on the outer side of the lower end plug shaft 522 and is rotatably connected thereto; one end of the supporting arm 525 is sleeved on the outer side of the upper end plug shaft 523 and is rotatably connected thereto, and the other end of the supporting arm 525 is rotatably connected to the containing assembly 51, so that the driving arm 524 and the supporting arm 525 adjust the position state of the barrel cover 520. When the output end of the opening and closing motor 53 drives the driving arm 524 to deflect upward, the deflection support of the driving arm 524 and the supporting arm 525 drives the barrel cover 520 and the structure fixed above it to move and deflect upward accordingly, and completes the opening operation of the rubber barrel 510. When the output end of the opening and closing motor 53 drives the driving arm 524 to deflect downward, the deflection support of the driving arm 524 and the supporting arm 525 drives the barrel cover 520 and the structure fixed above it to move and deflect downward accordingly, and the covering operation of the rubber barrel 510 can be completed. The driving arm 524 and the support arm 525 are all movable through the middle cavity of the side bracket 516 to avoid interference.
