A paper machine is a machine that makes paper pulp that meets the papermaking requirements after beating and modulation. According to this definition, the paper machine should start from the main pulp inlet pipe of the headbox or the pulp feeding system that must be attached to it until the paper reel that rolls out the paper roll. That is to say, the main body of the paper machine is divided into The wet section of the wet paper and the dry section where the wet paper is dried and rolled into a roll. The former includes three parts: a flow section, a forming section, and a press section, and the latter includes a drying section, a calender section, and a roll section. part. In addition, there are mechanical transmission parts and the vacuum system, air pressure and hydraulic system, lubrication system, paper threading system, steam system, hot air system, steam hood and its exhaust system that are indispensable for the operation of these main parts, which are also paper machines. The body part.
In addition, the white pool, lost paper pool, and hydraulic pulper required to deal with the white water, wet paper edges, wet damaged paper, dry damaged paper, etc. that are inevitably produced by the paper machine can be regarded as a single independent equipment, or It is regarded as the accessory equipment of the paper machine, but most of them are regarded as independent equipment. Many paper machines are also equipped with sizing press, in-machine coating, creping device, slitting machine and other equipment due to technological requirements. For a complete paper machine designed according to specific requirements, these are used as in-machine configuration The equipment should be regarded as the main part of the paper machine.
The electrical drive system, process parameter detection system, automatic control system, etc. of all parts of the paper machine should also be regarded as the main part of the paper machine.
