The straw molding machine adopts the interaction principle of extrusion force and die hole friction force between the flat mold block and the pressing wheel to make the material be formed. There is no need to add any additives or binders to the material during processing. Straw and other materials contain a certain amount of cellulose and lignin, whose lignin is the structural monomer in the material and is a phenylpropane-type polymer compound.
Straw can strengthen cell wall and bind cellulose. Lignin is amorphous, and its main part is insoluble in any solvent at normal temperature. It has no melting point, but has soft spots. When the temperature reaches a certain value, the soft binding force of lignin increases, and under a certain pressure, the cellulose molecular clusters are dislocated, deformed, and extended, and the adjacent biomass particles inside are interconnected, reassembled and pressed into shape.
1. High degree of automation, high output, low price, low power consumption, simple operation, convenient movement, diesel engine can be used to replace without power facilities.
2. Strong material adaptability: It is suitable for the shaping of various biomass raw materials. Straw can be processed from powder to 55mm in length and moisture content between 5-30
3. Electric heating function: automatic electric heating device, which can adjust the dry and humidity of materials, and solve the difficulty of non-blocking and non-forming.
4. Automatic adjustment function of pressure wheel: automatically adjust the pressure angle based on the principle of two-way rotation of thrust bearing, so that the material will not be squeezed and stuffy, and ensure the stability of discharge molding
5. Simple operation and convenient use: high degree of automation, less labor, only 3 people are needed, manual feeding or automatic feeding of conveyor can be used
6. Process flow: crushing → transportation → molding → warehousing of finished products
