Cutting device for kraft liner board production

Abstract

The invention discloses a cutting device for kraft liner board production, relates to the technical field of kraft liner board production, and provides the following scheme for solving the problems that when an existing kraft liner board is manually cut, the efficiency is low, the cutting uniformity is inconvenient to control, and material waste is caused. The cutting device comprises a placementplate, a fixed seat is fixedly connected to the right side of the top of the placement plate, a push rod motor is fixedly connected to the top of the fixed seat, a mounting plate is fixedly connectedto an output shaft of the push rod motor, a rack is connected to the top of the mounting plate in a height direction, and a movable cutting mechanism is slidably arranged at the top of the left side of the mounting plate; and a baffle is fixedly connected to the left side of the top of the placement plate, and a pressing mechanism is arranged between the baffle and the mounting plate. According tothe cutting device, the cutting efficiency of packaging paperboards and the cutting regularity of the paperboards are facilitated, the waste condition is reduced, the paperboards can be convenientlyand automatically positioned during cutting, and saving time and high efficiency are achieved.

Description

technical field [0001] The invention relates to the technical field of kraft liner board production, in particular to a cutting 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, et...
