Description

Technical Field

[0001] The utility model relates to the technical field of gluing machines, in particular to a gluing machine used for producing cartons. Background Art

[0002] Cartons are one of the common packaging materials. During the use and molding process of cartons, the edges of the cardboard need to be glued and bonded to form and fix the cartons to increase the strength of the cartons. This requires the use of a gluing machine. Most existing gluing machines are composed of a conveyor belt and a glue spraying mechanism. When gluing, the carton is placed on the conveyor belt and conveyed to the glue spraying mechanism by the conveyor belt for gluing.

[0003] And in the application document with publication number CN220297962U, a carton production gluing machine is mentioned. The gluing machine connects a glue spraying head with an external glue supply device so that the glue in the external glue supply device can be sprayed out through the glue spraying head, and then adjusts the distance between the two sets of limit baffles according to the size of the carton, starts the first motor, drives the bidirectional threaded rod connected to it to rotate, and the bidirectional threaded rod drives the sprocket on it to rotate, and through the transmission action of the chain, makes several sets of bidirectional threaded rods rotate synchronously, and the bidirectional threaded rod drives the two sets of adjustment plates to approach or move away from each other, thereby driving the two sets of limit baffles to approach or move away from each other, and after the distance is adjusted appropriately, turns off the first motor, and loosens the fastening bolt so that the connecting rod can slide up and down on the adjustment plate, and the height of the limit baffle can be adjusted through the connecting rod. After the limit baffle is adjusted to the appropriate height, it is only necessary to tighten the fastening bolt to fix the connecting rod. When the carton needs to be glued, the carton is placed on a conveyor belt, which is then conveyed to the bottom of the glue spraying assembly by the conveyor belt, and glue is sprayed onto the carton by the glue spraying head to achieve gluing. During gluing, the glue spraying head can be driven to move according to usage requirements, and the second motor can drive the screw to rotate, and the screw drives the movable plate to move, thereby driving the glue spraying head to move, and the cylinder can drive the glue spraying head to rise and fall, thereby better meeting the gluing requirements. The scraper and roller brush can clean up the glue dripping on the conveyor belt or other impurities on the conveyor belt in time, and the cleaned impurities can be collected by the collection box, but there are still certain defects that need to be optimized. The specific defects are as follows: Although the glue spraying head can move horizontally and vertically, it lacks sufficient angle adjustment capability to adapt to the surfaces of cartons of different shapes and angles. The scraper and roller brush cannot completely remove all impurities, especially for stubborn stains or dried glue.

[0004] Therefore, it is particularly important to design a gluing machine for producing cartons to change the above-mentioned technical defects and improve overall practicality. Utility Model Content
