Environment-protecting dispensing device with controllable adhesive spreading amount for plywood processing

Abstract

The invention discloses an environment-protecting dispensing device with controllable adhesive spreading amount for plywood processing. The dispensing device comprises a pipeline, a fixing device andadhesive spraying heads, wherein a connecting rod is arranged on the pipeline in an integrally formed mode, and the other end of the connecting rod is arranged on an upper cover disc in an integrallyformed mode; and a first circular through groove is formed in the upper cover disc in a penetrating mode, a clamping groove is formed in the side of the first circular through groove, a calibration rod is arranged on one side of the upper end of the upper cover disc in an integrally formed mode, a first fixing convex ring is arranged on the side of the bottom end of the upper cover disc in an integrally formed mode, and a fixing device is arranged on the upper cover disc. According to the environment-protecting dispensing device with the controllable adhesive spreading amount for the plywood processing, the adhesive spraying heads with different diameters can be adjusted and converted according to needs in the adhesive spreading work, and the adhesive spreading amount is controlled so thatthe optimal adhesive spreading work can be achieved, waste is avoided while the adhesive spreading work quality is guaranteed, therefore not only is the work efficiency improved, but also work economic benefits can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of plywood production and processing equipment, in particular to an environment-friendly glue dispensing device for plywood processing with controllable glue amount. Background technique [0002] Plywood (English: Plywood, commonly known as: multi-layer board) is one of the commonly used materials for furniture. It is a kind of wood-based panel; The three-layer or multi-layer plate-like material is usually made of odd-numbered veneers, and the fiber directions of adjacent veneers are glued to each other perpendicularly. both sides of the core. The slabs made of gluing veneers criss-crossed according to the direction of wood grain are pressed under heating or non-heating conditions; the number of layers is generally odd, and a few have even numbers. The difference in physical and mechanical properties in the vertical and horizontal directions is small; commonly used are three-plywood, five-plywood, etc.; pl...

Problems solved by technology

[0003] During the production and processing of plywood, it is very important to glue the plywood. The quality of the glue has an important impact on the quality of the finished plywood. The existing glue openings for the glue coating of the glued board usually only have one caliber, which cannot be applied to the plywood. The amount of gluing is controlled, which causes waste of glui...
