Description

Technical Field

[0002] Kraft bags are a type of packaging container made of composite materials or pure kraft paper. They are non-toxic, odorless, pollution-free, low-carbon, environmentally friendly, and high-strength. They are currently one of the most popular environmentally friendly packaging bags in the world.

[0003] In the production process of traditional kraft bags, it is necessary to apply glue to the sealing part of the kraft paper bag and seal it by gluing. When sealing the kraft paper bag, the kraft paper bag is directly placed on a conveyor belt for conveying and gluing without limiting the kraft paper bag. Slipping or position shifting may occur, thereby affecting the quality of gluing. In addition, during the long gluing process, a large amount of glue liquid needs to be stored in the glue storage barrel. The glue liquid is prone to precipitation after being stored for a long time, resulting in uneven gluing of the kraft paper bag, affecting product quality. Utility Model Content

[0029] Working principle: In actual use, by starting the first motor 3, the first rotating shaft 31 is driven to rotate, that is, the first bevel gear 24 and the second bevel gear 32 are driven to rotate, thereby driving the driving wheel 23 to rotate, and the driving wheel 23, the belt 231 and the driven wheel 232 cooperate with each other to make the belt 231 rotate. At the same time, the conveyor belt 25 and the first motor 3 are connected through the transmission belt, so that the conveyor belt 25 rotates, and the kraft paper bag that needs to be glued is placed on the upper part of the conveyor belt 25 and the two electric push rods 41 are started, so that the two belts 231 move relative to each other, so that the belt 231 and the side of the kraft paper bag contact each other, and then the kraft paper bag is limited and cooperated with the conveyor belt 25 to convey the kraft paper bag. After passing through the lower part of the glue coating device 42, the glue in the glue storage barrel 5 is extracted by the glue pump to glue the kraft paper bag;

[0030] By placing the glue to be glued inside the glue storage barrel 5, and starting the second motor 51, the third bevel gear 511 and the fourth bevel gear 53 are driven to rotate, thereby driving the second rotating shaft 531 and the third rotating shaft 532 to rotate. Under the rotation of the second rotating shaft 531, the turntable 54 is rotated, that is, the scraper 541 is driven to rotate, and the glue attached to the inner wall of the glue storage barrel 5 can be scraped off, and the stirring rod 551 can be driven to revolve with the turntable 54. At the same time, the rotation of the third rotating shaft 532 drives the first gear 55 to rotate, that is, drives the second gear 56 to rotate, thereby driving the stirring rod 551 to rotate with the second gear 56, that is, the glue inside the glue storage barrel 5 is stirred.
