Description

Technical Field

[0001] The utility model relates to the field of corrugated board processing, in particular to a corrugated board thickening and gluing device. Background Art

[0002] Corrugated cardboard is also called corrugated cardboard. Sometimes, according to special production requirements, the original corrugated cardboard needs to be thickened. Generally, the thickened layer is glued to the surface of the corrugated paper and then pressed together.

[0003] During the gluing process of the existing corrugated cardboard thickening, the gluing device cannot evenly apply glue to the surface of the cardboard. Excessive glue will overflow from both sides, affecting the factory quality of the cardboard. At the same time, the corrugated cardboard and the thickening layer will easily move during the transmission process, which will also affect the gluing effect. Utility Model Content

[0006] Preferably, in the first step, the corrugated cardboard and the thickened cardboard enter from the feed port on the left side of the operating room, pass through the uniform distribution roller and the pressing roller in sequence, and then are output from the discharge port; in the second step, the staff adjusts the positioning component according to the width of the corrugated cardboard and the thickened cardboard to reduce the space on both sides of the corrugated cardboard and the thickened cardboard, and the positioning component restricts the cardboard movement range from both sides, ensuring that the cardboard remains in the middle during the transmission process and is not easy to move; in the third step, after starting the gluing equipment, the collecting component extracts the glue from the lower end and sprays it to the inner side of the corrugated cardboard and the thickened cardboard, and when passing through the uniform distribution roller, The glue is evenly distributed, and the excess glue is absorbed by the uniform distribution roller with a water-absorbing layer on the outside. The material of the water-absorbing layer can be sponge or thick cloth; when the uniform distribution roller rotates, the collecting component moves back and forth at the end far away from the pasting surface, and the glue absorbed by the collecting component is scraped off and collected, and after filtering, it is used again; in the fourth step, the first pressing roller then presses the corrugated cardboard and the thickened cardboard together, and the drying plywood heats the upper and lower sides of the thickened corrugated cardboard at the same time to dry the glue, and the second pressing roller presses the corrugated cardboard and the thickened cardboard again to improve the flatness of the thickened corrugated cardboard.

[0013] Beneficial effects of the utility model:

[0014] The utility model provides a positioning component at the feed port, and the space on both sides can be adjusted according to the width of the corrugated cardboard and the thickened cardboard.
