Glue liquid level controllable corrugated paper single facer based on theory of communicating vessel

Abstract

The invention relates to the technical field of corrugated boards and discloses a glue liquid level controllable corrugated paper single facer based on a theory of a communicating vessel. The glue liquid level controllable corrugated paper single facer comprises a rack body, wherein an upper corrugated roller is movably connected in the rack body, a lower corrugated roller is movably connected outside the upper corrugated roller, a paper pressing roller is movably connected outside the lower corrugated roller, a paper guiding roller is movably connected outside the paper pressing roller, a gumming roller is movably connected outside the lower corrugated roller, a scraper blade is movably connected outside the gumming roller, an adjusting rod is fixedly connected outside the scraper blade,an adjusting spring is connected outside the adjusting rod in a sleeving manner, and an adjusting nut is connected outside the adjusting rod by a thread. By matching the scraper blade, a coating roller and the gumming roller in use, the uniformity of glue on the surface of the gumming roller is guaranteed and the uniform gumming effect is achieved, so that the bonding quality of core paper and theboard is guaranteed effectively and the quality of the corrugated board is improved.

Description

technical field [0001] The invention relates to the technical field of corrugated cardboard, in particular to a corrugated cardboard single-facer with controllable colloid liquid level based on the principle of a connecting device. Background technique [0002] Corrugated cardboard, also known as corrugated cardboard, is a multi-layer adhesive body. It is composed of at least one layer of wavy core paper interlayer and one layer of cardboard. Support each other to form a triangular structure, which has good mechanical strength, can withstand a certain pressure from the plane, is full of elasticity, and has a good cushioning effect; it can be made into liners or containers of various shapes and sizes according to needs. It is simpler and quicker than plastic buffer materials; it is less affected by temperature, has good shading properties, does not deteriorate under light, and is generally less affected by humidity, but it is not suitable for long-term use in an environment w...

Problems solved by technology

[0003] However, the existing single-sided machines have high energy consumption, low technical threshold, high control complexity, uneven gluing on the flute peaks of corrugated paper, difficulty in controlling the amount of gluing, and even impossible to adjust and control according to different materials of corrugated cardboard. The amount of glue applied, uneven glue application will affect the bonding between the core paper and the cardboard, resulting in unqualified corrugated cardboard quality, and the single-sided machine, the trouble of adding glue, often only the glue inside the glue box, and The height of the glue surface is controlled by controlling the height of the glue box. Due to the continuous consumption of glue, the glue box needs to be raised frequently synchronously. The operation is very troublesome, and the amount of glue stored in the glue box is limited, so it is necessary to add glue repeatedly, which is wasteful. Working hours, reduced productivity in corrugated board production
