Description

Technical Field

[0001] The invention relates to the technical field of corrugated board processing, in particular to a gluing device and a method for corrugated board processing. Background Art

[0002] Corrugated cardboard is a multi-layer adhesive body, which is composed of at least one layer of corrugated core paper (commonly known as "corrugated paper", "corrugated core paper", "corrugated paper core", "corrugated base paper") and one layer of cardboard (also known as "boxboard", "boxboard"). It has high mechanical strength and can withstand collisions and falls during transportation. When processing corrugated cardboard, gluing equipment is needed to gluing the corrugated cardboard;

[0003] The gluing equipment in the prior art uses a rotating conveyor belt to transport the corrugated cardboard to be glued, and then a cleaning structure is provided to clean the upper surface of the corrugated cardboard before gluing, and the cleaned impurities are collected in a collection box to avoid impurities adhering to the surface of the corrugated cardboard, which may cause uneven gluing.

[0004] However, after the corrugated cardboard is coated with glue, it is continuously transported by a rotating conveyor belt, and is manually transferred to the next processing step. This takes a long time to transfer the glued corrugated cardboard to the next step, which is time-consuming and labor-intensive. In addition, the glue on the corrugated cardboard is prone to solidification. In addition, during the transfer process, dust in the air is prone to adhere to the glue on the corrugated cardboard, which reduces the quality of the gluing.

As the conveyor belt 4 drives the corrugated cardboard to continue to move, the dust adhering to the corrugated cardboard can be cleaned. At the same time, the cleaning plate 37 drives the limit plate 41 to move downward to the front and rear sides of the corrugated cardboard, and the second roller on the L-shaped rod 44 is used to move the corrugated cardboard. 45, in the process of cleaning the corrugated cardboard, the corrugated cardboard is limited to avoid the problem of position deviation of the corrugated cardboard on the conveyor belt 4, and the suction fan 46 can suck the dust generated in the cleaning process in the cleaning cover 35 into the water tank 48 to prevent the cleaned dust from floating directly in the surrounding air. After cleaning, the conveyor belt 4 drives the corrugated cardboard to move to the U-shaped plate 49, and the glue in the glue storage cylinder 50 is sprayed onto the corrugated cardboard through the glue spray head 53 to apply glue. After applying glue, the first electric telescopic rod 17 is started to drive the top plate 16 to move downward. When the bottom A storage plate 14 moves down to the feed port 9, and the push-pull groove 20 on the corresponding storage plate 14 moves down to the push-pull block 19, and the second electric telescopic rod 21 is started to drive the push-pull block 19 to move toward the side close to the gluing rack 1, and the squeezing wheel 28 on the storage plate 14 moves to squeeze the inclined surface of the squeezing plate 26, pushing and the squeezing plate 26 drives the baffle 22 to move down at the feed port 9 to open the feed port 9, and then the storage plate 14 moves out of the feed port 9 to the conveyor belt 4, and the conveyor belt 4 is rotated to transport the glued corrugated cardboard to the storage plate 14, and then the storage plate 14 is reversed. Move to the transfer frame 6, the heating tube 10 in the transfer frame 6 increases its internal temperature, delays the solidification of the glue on the corrugated cardboard, and does not cause the corrugated cardboard to be scorched. Then, the next corrugated cardboard is cleaned, glued, and transferred to the remaining storage plate 14 in the transfer frame 6. Finally, the bottom end of the second handle 32 is pulled out from the positioning hole 30, and the plug 29 is pulled out from the sleeve frame 31 to release the positioning of the transfer frame 6 on the glue coating rack 1, and then the transfer vehicle 5 is pushed to drive the glued corrugated cardboard in the transfer frame 6 to be transferred to the next processing step.
