Embodiment

[0025] like figure 1 , figure 2 and image 3 As shown, a production system for environmentally friendly boxboard paper includes a pulping mechanism, a forming mechanism and a drying mechanism. There are dryers for containerboard production in the art. The forming mechanism includes a forming wire 12, the forming wire 12 is connected end to end, the forming wire 12 is connected with a driving mechanism, and the driving mechanism is used to drive the forming wire 12 to rotate. In this embodiment, the driving mechanism includes a driving wheel 11 and a driven wheel 14. The driven wheels 14 are all rotatably installed on the frame, the forming mesh 12 is tensioned on the driving wheel 11 and the driven wheel 14, and the driving wheel 11 is connected with a motor.

[0026] In this embodiment, the left end of the forming wire 12 is the feeding end, and the right end is the feeding end. A bottom pulp headbox 1, a core pulp headbox 7 and a face pulp headbox 9 are sequentially ins...

Abstract

The invention relates to the technical field of papermaking, in particular to a production system for environmentally friendly containerboard paper, comprising a forming mechanism, the forming mechanism comprises a forming wire, the forming wire is connected end to end, the forming wire is connected with a driving mechanism, and the driving mechanism is used to drive the forming wire to rotate, Above the forming wire, from the feeding end to the discharging end of the forming wire, a bottom pulp headbox, a core pulp headbox and a face pulp headbox are sequentially installed. A dewatering channel for dewatering the pulp is formed between them. The bottom pulp headbox, the core pulp headbox and the face pulp headbox are all connected with a spray pipe at the bottom. A blower is installed between the bottom pulp headbox and the core pulp headbox. A blowing mechanism is also installed between the core pulp headbox and the face pulp headbox. The invention solves the problem of insufficient bonding force among the bottom paper, core paper and face paper of the boxboard paper in the prior art.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to a production system for environmentally friendly containerboard paper. Background technique [0002] Containerboard paper, also known as kraft paper and kraft paper, is one of the main paper types for carton paper. Containerboard is mainly used for packaging household appliances, daily necessities, knitted cotton fabrics, stationery, outer packaging of Chinese and Western medicines, etc. The requirements for the box board are that it should have a certain compressive strength, toughness and break resistance, tear resistance, smooth paper surface, and no pulp bumps, knots and uneven appearance of paper defects. [0003] The production of boxboard paper generally includes processes such as pulping, pressing, forming, drying, sizing, calendering, and rolling paper. The forming process is a combination of bottom paper, core paper and face paper. In the prior art, bottom paper, ...
