[0001] The invention relates to the technical field of liquor packaging box processing, in particular to an automatic glue spraying machine for liquor packaging box processing which can prevent nozzle clogging. Background Art

[0002] As the name implies, a packaging box is a box used for packaging. Most of the materials are made of cardboard. With the continuous maturity of technology in recent years, the types of packaging boxes have gradually increased, and packaging boxes made of some plastics, composite materials and other materials have also increased. Packaging boxes are widely used and the demand is increasing. In addition, with the increasing living standards, people have higher and higher requirements for the aesthetics of packaging boxes. For example, bottled wine packaging boxes are very popular among users for their beautiful appearance. In the production process of liquor packaging boxes, gluing is required to ensure that the base and the inner box are glued and pressed together.

[0007] Furthermore, the drying machine is located on the right side of the glue box, and the supporting plate is located below the glue storage cylinder.

[0008] Furthermore, the bottom end of the rubber delivery pipe is fixedly connected to the conveying cylinder, and the rubber delivery pipe is a corrugated pipe, and the movable plate is slidably installed on the front side of the supporting plate.

[0009] Furthermore, a mounting cavity is provided inside the movable plate, a movable opening is provided on the front side of the movable plate, and the connecting rod is slidably installed inside the movable opening.

[0010] Furthermore, one end of the inner sleeve close to the connecting shaft is an inclined surface, and the top end and the bottom end of the partition are fixedly connected to the inner wall of the dispensing cylinder respectively.

[0016] Compared with the prior art, the technical solution of this application has the following beneficial effects: 1. The automatic gluing machine for processing liquor packaging boxes which can prevent nozzle clogging has a gluing box. During the gluing process, the liquor packaging box is fed into the gluing box through a conveyor belt. The movable plate is driven to move left and right on the front of the support plate by the action of the drag chain, and the output shaft of the driving motor drives the lead screw to rotate through the belt. After the lead screw rotates, the screw sleeve is driven to rotate. However, since the screw sleeve is limited by the connecting rod, it cannot rotate, and the screw sleeve should be movable. Therefore, the screw sleeve is moved up and down on the lead screw to drive the electric slide rail to move up and down. At the same time, the electric slide rail will drive the two gluing mechanisms to move left and right to adjust the gluing distance, thereby performing multi-directional movement inside the gluing box for automatic gluing, which can be freely adjusted according to needs to improve the gluing efficiency.

[0017] 2. The automatic glue-spraying machine for processing white wine packaging boxes that can prevent nozzle clogging has a glue-spraying mechanism. During the glue-spraying process, the glue in the glue storage cylinder will be fed from the glue delivery pipe into the interior of the conveying cylinder. The conveying cylinder will convey the glue from the corrugated hose to the interior of the two glue-spraying cylinders. The glue will flow into the storage cavity on the rear side of the partition. The stirring rod will rotate under the drive of the servo motor. The stirring rod will stir the glue so that it will not solidify and become viscous, thereby avoiding clogging of the glue-spraying head. The hydraulic cylinder will press into the interior of the glue-spraying cylinder, push the piston downward, and push the glue out from the glue-spraying head for glue-spraying. After the glue-spraying is completed, the hydraulic cylinder sucks up the piston and moves it upward. During the movement, the sealing plate will be pushed upward, and the stretching spring will contract, thereby opening the conveying hole. The glue enters from the rear side of the partition to the front side of the partition for the next glue-spraying. After the blockage occurs, the power of the hydraulic cylinder is increased to push the blockage, increase the internal pressure, avoid blockage, and increase the glue-spraying efficiency at the same time, thereby improving the efficiency of white wine packaging box production.

[0027] In this embodiment, the inner sleeve 1503 is cylindrical and fixed inside the glue dispensing cylinder 1501. The upper part of the inner wall is designed to be inclined to facilitate the transportation of glue and avoid blockage. The partition 1504 divides the glue dispensing cylinder 1501 into two front and rear storage chambers. The piston 1508 is installed in the front storage chamber, and the stirring rod 1506 is in the rear storage chamber.

[0028] In this embodiment, the servo motor 1505 is designed on the back of the dispensing head 1509, and the stirring rod 1506 is driven by the servo motor 1505 to rotate and stir inside the rear storage cavity.

[0029] In this embodiment, the outer surface of the piston 1508 is in close contact with the inner wall of the front storage chamber. When the piston 1508 moves upward, it will push the sealing plate 1512 upward, and the tension spring 1513 will be stretched. After the sealing plate 1512 moves, the delivery hole 1510 will lose its seal.
