Description

Technical Field

[0002] When producing boards, usually multiple veneers are glued together to form a slab, and then pressed under heating or non-heating conditions. At present, the gluing operation of veneers has achieved semi-automatic or automatic operation. Gluing is usually carried out using a glue roller. The glue is transported to the glue roller through a glue storage tank. The veneer is transported through the rotating glue roller to achieve gluing of the board. There are many ways to transport glue to the glue coating roller, such as the Chinese utility model patent with application number "202320493474.9" and name "glue coating device". In this patent, the mobile roller (glue coating roller) is equipped with a liquid roller, and the liquid roller is at least partially located in the storage chamber. The liquid roller is used to transport the colloid in the storage chamber to the outer surface of the mobile roller. When this patent is implemented, the glue in the storage chamber gradually decreases as the work progresses, and it is necessary to observe and control it manually or with special equipment, which is costly; another example is the Chinese utility model patent with application number "202322663934.0" and name "glue coating device". In this patent, a glue coating component is provided at the opening at the bottom of the glue storage tank. Through contact with the glue coating roller, the glue in the glue storage tank flows from the avoidance groove into the movable block, flows through the glue flow groove, and then flows out from the bottom of the movable plate to the glue coating roller. Although this patent can well control the amount of glue, the structure is too complicated. Utility Model Content
