Learn about the production process and principles of egg tray production equipment
Egg tray production equipment is a special equipment used to produce egg trays. Its production process involves raw material preparation, molding, drying, packaging and other links. This article will introduce in detail the production process and principles of egg tray production equipment.
1. Raw material preparation
The main raw materials of egg trays are waste paper and water. During the production process, the waste paper needs to be chopped and mixed with water to make pulp.
2. Forming
Molding is the core link of egg tray production equipment. Its principle is to inject paper pulp into the forming mold, and after a series of operations, an egg tray with corresponding shape and size is formed.
1. Preparation of forming mold: In egg tray production equipment, the forming mold is a key component, and its production needs to be designed and processed according to the specifications and dimensions of the egg tray. The forming mold is made of metal material and has certain strength and wear resistance.
2. Grouting: Pour the prepared pulp into the grouting port, and control the flow rate and temperature of the pulp through the control system to evenly inject the pulp into the mold.
3. Rapid drainage: After grouting, the forming mold is quickly vibrated or given a certain amount of pressure to accelerate the removal of water and shape the pulp.
4. Hot and cold pressing: Send the egg tray mold formed from pulp into the heating system, and undergo certain temperature and pressure treatment to make the pulp molding stronger and more stable.
5. Demolding: After the egg tray is formed, the mold is sent to the demoulding machine, and the formed egg tray is taken out of the mold through a motion device or suction cup to form the finished product.
3. Drying
After the egg tray is formed, it needs to be dried to lose excess moisture and enhance the hardness and stability of the product. The principle of drying is to use hot air to heat and evaporate the egg tray, so that the water evaporates and is quickly eliminated.
1. Hot air heating: Put the egg tray into the dryer and heat it with the hot air supplied from outside, so that its surface temperature gradually increases.
2. Water evaporation: As the temperature increases, the water in the pulp evaporates into water vapor and is gradually eliminated. During this process, the temperature and flow rate of the hot air can be controlled so that the egg tray is evenly heated and the water evaporates evenly.
3. Cooling: After drying, the egg tray needs to be cooled to lower its temperature. The cooling method can be natural cooling from the outside or accelerated cooling through a cooling system.
4. Check the quality: After cooling, the egg trays are quality checked to ensure that they meet production requirements and classified and graded.
4. Packaging
Once the egg trays are produced, they need to be properly packaged for transportation and sale.
1. Packaging materials: Common packaging materials include plastic bags, cartons, etc. Choose the appropriate packaging materials according to your needs.
2. Packaging machinery: Depending on the packaging materials and production scale, packaging machinery can choose manual packaging or automatic packaging equipment. Automatic packaging equipment can realize automatic distribution and packaging of egg trays, improving production efficiency and packaging quality.
3. Labels and logos: After packaging is completed, labels and logos need to be affixed to the egg trays to distinguish the variety, production batch and other information.
To sum up, the production process of egg tray production equipment mainly includes raw material preparation, molding, drying and packaging. Through reasonable operation and control, efficient, stable and high-quality egg tray production can be achieved.
