Embodiment Construction

[0026] The object of the present invention is to provide a production method of packaging cardboard and its production equipment. It is characterized in that: the production method of the packaging cardboard is a method for producing corrugated cardboard by molding at one time, and the specific production steps are as follows:

[0027] 1) Molding:

[0028] exist figure 1 In the structural schematic diagram of the one-time forming cardboard equipment shown, the prepared waste paper pulp or straw pulp is adjusted to a concentration of 1% by weight, and is sent from the feed pipe 1 to the slurry tank 2 of the forming part of the production line. Shaper 4 is installed on slurry tank 2 tops, and bearing 14 supports are arranged on both sides (as figure 2 Shown), it is as the criterion that 60~70% of the circumference of the former is submerged in the slurry tank 2. The take-up roller 6 is installed between the former 4 and the drier 8, respectively abutting against them, and th...

Abstract

The present invention relates to packing and building material, and is especially packaging paper board producing process and apparatus. The packaging paper board is corrugated paper board and its production process includes the following steps: preparing paper pulp, forming the pulp in the surface of the forming device, continuous vacuum suction pumping to dewater, drying, setting and final adhering the facing layer. The corrugated paper board has high strength, and the production process includes papermaking and forming paper board. The product is used in packing, as building material, etc.

Description

technical field [0001] The invention belongs to the scope of packaging materials and building materials. In particular, it relates to a production method and equipment for packaging cardboard. Background technique [0002] At present, corrugated cardboard is widely used in the packaging industry to manufacture various packaging boxes. Usually the production of corrugated cardboard is to produce flat corrugated base paper through the papermaking production line of the paper mill; surface, and finally made into corrugated cardboard. This kind of production process is long, and the papermaking production line also needs to discharge a large amount of waste water, and the product is produced through two production lines, so the operation is complicated and the cost is high. At the same time, because the source of the base paper is sometimes inconsistent, the quality of the corrugated cardboard is unstable, and the machine-pressed corrugated type is easy to cause lodging when ...
