How does the Paper Making Machine work？

The High Precision Paper Making Machine is a kind of paper-making machinery that is necessary for every paper mill.The appearance of Nice Performance Paper Making Machine the traditional hand-made paper,which not only improves the quality of paper but also improves the production efficiency.Then everyone is not sure about the working principle of the Paper Machine For special understanding,let the me give you a brief introduction of Good Quality Paper Making Machine:

Nice Performance Paper Making Machine

If the Good Quality Paper Making Machine is divided according to the different structure of the wire part,Nice Performance Paper Making Machine can be divided into fourdrinier type,rotary wire type,clamp wire type,stacked wire type and facing roller.High Precision Paper Making Machine can be said to be a linkage machine composed of multiple devices.The parts of the machine are divided into two parts,the wet part and the dry part.Wet end components include stock flow equipment,wire and press sections;dry ends include dryers,calenders and reels.

The raw materials are turned into pulp with papermaking performance through pulping,sizing,filling and purification,and then the pulp is sent to the pulp flow equipment of the paper machine at a concentration of 0.3%-1.3%.After the distribution and leveling of the headstock by the stock flow distributor and the headbox,the stock will be evenly and stably transported to the running forming screen.The pulp flow is filtered and dehydrated on the wire table to gradually form a continuous wet paper web.The mesh table components are mainly equipped with table rollers,vacuum suction boxes,couch rollers and other forming and other dehydration parts.When the wet paper web formed on the wire table is dehydrated until the moisture content reaches about 20%,it can be peeled off from the wire surface and sent to the press section for further dehydration.

The press section is composed of several groups of roller presses.The wet paper web is supported by press felts and dehydrated by mechanical extrusion between the press rollers.In order to maintain the good dehydration performance of the press felt,the upper press roll is equipped with a felt washing device.After the press section,the dryness of the wet paper web can generally reach about 40%.

The wet paper web dehydrated by the press section needs to be further dehydrated by heating and drying. The drying section of the High Precision Paper Making Machine is composed of many drying cylinders,which can be heated from the inside by steam.The drying cylinder is covered with a dry felt to Press the paper web tightly on the surface of the cylinder to improve heat transfer efficiency.After thorough drying, a calender consisting of 6-8 rolls is used to improve the overall web surface quality.
