Glue supply device for corrugated carton gluer

Abstract

The invention discloses a glue supply device of a carton sticking machine of a corrugated paper box, and belongs to the technical field of carton sticking machines. The glue supply device of the carton sticking machine of the corrugated paper box comprises a glue supply device, a glue coating device and an extrusion plate, wherein an air cylinder is arranged between the extrusion plate and the glue supply device, the glue coating device comprises a first cavity and a second cavity, wherein the first cavity can be used for containing an extruding plate, and the second cavity is just capable ofcontaining the second cavity of the extruding plate; a second balance plate is arranged on one side, opposite to the extrusion plate, of the glue coating device, the second balance plate is in slidingconnection with the glue coating device, and one side, far away from the extrusion plate, of the second balance plate is provided with a glue coating head. According to the device, the glue amount ofglue coating is accurately controlled by controlling the movement process of the air cylinder, meanwhile, the position of the gluing position and the uniformity of the gluing are accurately controlled through the second balance plate and the gluing device, so that the position precision and the gluing quality of the gluing can be improved; and meanwhile, the device is simple in structure, low incost and cleaning can be conveniently carried out.

Description

technical field [0001] The invention belongs to the technical field of box gluers, and more specifically relates to a glue supply device for a box gluer of corrugated cartons. Background technique [0002] Corrugated paper is a plate made of liner paper and corrugated corrugated paper formed by processing corrugated sticks. It is generally divided into two types: single corrugated board and double corrugated board. According to the size of the corrugated board, it is divided into: A, B, C , E, F five types. Type A stare blankly made of corrugated board has good buffer, A degree of elasticity, C going A while at A type A. But the stiffness and impact resistance is better than that of type A stare blankly. But the stiffness and impact resistance are better than A-type flute; B-type flute has a large arrangement density, and the corrugated board made of it has a smooth surface and high bearing pressure, which is suitable for printing; E-type flute is thin and dense, and it sho...

Problems solved by technology

[0003] At present, there are two types of glue supply devices for automatic case gluers commonly used in the packaging industry. One is a self-flowing glue supply device. The glue flows from the glue barrel into the glue application box under the action of gravity. The disadvantage of this method is that the amount of glue is not easy to control, the amount of glue is large, the excess glue is easy to leak and the accuracy of the wiring is not easy to control; the other is a circulating glue supply device, and its main structure is a glue pump (usually a gear Pump), glue inlet pipe, glue return pipe, glue box, glue wheel, glue barrel, and valve. Its working principle is to pump glue from the glue barrel into the glue box through the gear pump to apply glue to the glue wheel. The excess glue in the glue box is returned to the glue barrel under the pressure of the pump. Although this method overcomes the shortcomings of the self-flowing glue supply, it brings new problems: (1). Glue, that is, contact glue with a round rolling surface, the manufacturing cost of the glue pump is high and the precision of the wiring is not high. (2) The temperature of the glue rises due to the heat generated by the glue pump during continuous operation, which makes the glue easy to deteriorate. (3) Clean the glue A large amount of residual glue and water are wasted during pumping, which not only pollutes the environment, but also increases the cost. (4), the thickness of the glue is not easy to control
