Automatic egg tray production line making machine workflow
1. Pulping system
(1) Put the raw material into the pulping machine, add an appropriate amount of water, and stir it for a long time to turn the waste paper into pulp, and then put it into the pulp storage tank for storage.
(2) Put the pulp in the storage tank into the mixing tank, adjust the pulp concentration in the mixing tank, and further stir through the white water in the return tank and the thick pulp in the storage tank through the homogenizer. After adjusting to suitable pulp, put it into the pulp supply tank to be used in the forming system.
Equipment used: pulper, homogenizer, pulp pump, vibrating screen, pulp decompressor
2. Forming system
(1) The pulp in the pulp supply tank is fed into the forming machine, adsorbed by the vacuum system, the pulp is passed through the mold on the equipment, and the pulp is left on the mold to form, and the white water is adsorbed and transferred back to the pool by the vacuum pump.
(2) After the mold is adsorbed, the transfer mold passes through the positive pressure of the air compressor, and the molded product is blown from the molding mold to the rotating mold, and some are sent out by the transfer mold.
Equipment used: molding machine, mold, vacuum pump, negative pressure tank, water pump, air compressor, mold cleaning machine
3. Drying system
(1) Natural drying method: directly rely on the weather and natural wind to dry the product.
(2) Traditional drying: brick-built tunnel kiln, the heat source can choose natural gas, diesel, coal, dry wood, liquefied petroleum gas and other heat sources.
(3) New multi-layer drying line: 6-layer metal drying line can save more than 30% energy than transmission drying, and the main heat source is natural gas, diesel, liquefied petroleum gas, methanol and other clean energy.
4. Auxiliary packaging of finished products
(1) Automatic stacker
(2) Baler
(3) Transfer conveyor
