3 corrugated board production line

3.1 corrugated board production line (hereinafter referred to as corrugated line) composition

3.1.1 corrugated line is generally composed of the following single machines and systems:

a. base paper support

b. preheater

c. single sided machine

d. pre regulator

e. paper loading trolley

f. conveying bridge

g. paper receiving machine

h. multiple preheaters (double, triple, etc.)

i. gluing machine

j. double sided machine

k. cutting machine

l. longitudinal cutting and indentation machine

m. paper separation bracket

n. crosscutting machine

o. conveyor

p. stacker

q. main conveyor

r. paper edge crusher

s. paste machine

t. steam heating system

u. compressed air system

v. electrical control system

3.1.2 a complete corrugated line should include stand-alone machines and systems for all processes of corrugated board production, and special equipment such as printing patterns, plastic coating and moisture-proof can also be simplified or added according to the needs of users

3.2 marking method by changing the internal geometric structure of the material

3.2.1 the marking of the tile line is composed of the code "WJ" of the tile line and the main parameters representing the performance. The first main parameter is the maximum speed, the second main parameter is the effective width, and the last number represents the number of corrugated boards produced

3.2.2 marking example:

the maximum speed is 100m/min, and the effective width is 1600mm, which will generate friction between the pendulum bearings to produce the corrugated line of double corrugated cardboard
