uncoiling paper production line

Specifications

Material Preparation: After quantitative measurement, put modified starch, retarder, paper pulp, water reducing agent and water in the hydrapulper to form a pulp of raw material, then pump them into the slurry storage tank as standby; proportionally put the foaming agent and water in foaming agent preparation tank and stir uniformly, then pump them into the foaming agent reserve tank (with heating device to keep the temperature at or above 35 °C) as standby; coagulant and gypsum powder raw materials enter into the silo as standby through elevating and conveying equipment.

Dosing: Use metering pump to pump the slurry into the mixer, use dynamic foaming device to foam the foaming agent and into a mixer, use automatic belt weigher to measure the coagulant and gypsum powder and into the mixer, then blend all the main and auxiliary materials in a mixer into qualified gypsum slurry.

Forming and Conveying Process:

The upper paper enters forming machine through automatic rectify deviation machine after uncoiling, the lower paper enters forming machine through automatic rectify deviation machine, scoring machine and vibration platform after uncoiling, the slurry of the mixer falls onto the lower paper of vibration platform and enters forming machine, the forming machine squeezes out plasterboard of requested specifications, and then finish the initial solidification on solidification belt and the final solidification on rollgang, use fixed-length cutting machine to cut the plaster board to a required length (2400mm,3000mm or others), the two plaster boards, after the redirection by cross steering machine 1#, leave the machine1# at the same time, use roller bed to make the spacing of the two boards to meet the requirements, and finally enter drying machine through distributor for drying.

Drying Process:

Using fuel type heat conduction oil furnace as the heat source, the hot oil, after goes through fin heat exchanger, becomes hot wind and enters drying machine to complete the drying task. The drying machine is divided into 2 areas, which can nicely finish the drying curve of gypsum board in drying process, avoiding defects such as over burning, wetting and so on. This process is environmental protective, energy saving, high thermal efficiency, and the process parameters are easy to control.

2# Cross Steering process

After the drying machine finishes drying task, the boards are conveyed to 2 # cross steering system via plate discharging machine to complete fixed-length cutting of the gypsum board and automatic edge sealing, then send them into automatic stacker for stacking through finished product conveyor. Use forklift to send the products to packing areas for inspection and packaging. The whole set of production process is complete.
