Gluing device for kraft box paperboard production

Abstract

The invention discloses a gluing device for kraft box paperboard production, and relates to the technical field of kraft box paperboard production. The gluing device aims at solving the problems thatmanual glue brushing is low in efficiency and cannot ensure the uniformity of glue brushing during existing paperboard gluing, and the viscosity of glue is influenced due to the fact that the bottom of the glue is easy to solidify after standing for a long time. According to the gluing device disclosed by the scheme, the gluing device comprises a bottom plate, supporting plates are fixedly connected to the two sides of the top of the bottom plate, lifting mechanisms are arranged on the sides, close to each other, of the two supporting plates, a glue box is arranged on the sides, close to eachother, of the two lifting mechanisms, a stirring mechanism is rotationally connected to the interior of the glue box, an intermittent discharging mechanism is fixedly connected to the bottom of the glue box, and a movable wiping mechanism is arranged below the intermittent discharging mechanism. According to the gluing device, the position of a brush roller can be conveniently adjusted, moreover,uniform blanking on the surface of the brush roller is facilitated, uniform smearing of the glue is facilitated, moreover, the glue can be synchronously stirred, and the glue is prevented from being solidified.

Description

technical field [0001] The invention relates to the technical field of kraft liner board production, in particular to a gluing device for kraft liner board production. Background technique [0002] Kraft liner board is also called liner board or kraft cardboard. The ratio of raw materials for the production of kraft box boards in foreign countries generally uses 100% natural kraft pulp, a few use natural kraft wood pulp vermicelli, and waste paper pulp is used as the core layer and bottom layer. Due to insufficient wood resources in China, 40% to 50% is used. %Wood pulp vermicelli, use one or two mixed pulps such as wheat straw pulp, straw pulp, miscanthus pulp, bagasse pulp, waste paper pulp as the core layer and bottom layer, and develop 100N bamboo pulp, or use 60% to 70% bamboo pulp Pulp and straw pulp or waste paper pulp, or 20% wood pulp and cotton stalk pulp and kenaf stalk pulp, etc., and finally after sizing and calendering to make kraft box board, its pulping, etc...

AI Technical Summary

Problems solved by technology

[0004] A gluing device for the production of kraft box board proposed by the present invention solves the problem of manual gluing when gluing the existing cardboard, and the manual gluing is not only inefficient, but also cannot ensure the uniformity of gluing, and the bottom of the glue remains static for a long time. Set the problem that it is easy to solidify and affect the viscosity of the glue
