Pulp moulding cushioning and shock-proof packaging is based on waste newspapers, waste cardboard paper, scraps from paper mills or printing plants, etc., and is formulated into a certain concentration of slurry through processes such as hydraulic pulping and batching; the slurry is on a special metal mold It is vacuum-adsorbed into a wet green product, and the formed wet green is then dried and hot-pressed to shape. The main raw material used in production is waste paper, which has rich sources and low prices, and is a comprehensive development and utilization of waste. To buy a new egg tray production line, go to Hongrun Packaging Machinery Co., Ltd.
After fulfilling its mission of buffering and shock-proofing protection of packaged materials in the circulation of goods such as storage, transportation, and sales; its waste can be recycled and reused like ordinary paper, even if it is abandoned in the natural environment. Like ordinary paper, it is easy to rot and decompose into plant fibers.

The drum is an egg tray production equipment forming machine, also called a rotary polygon forming machine. Common drum-type molding machines are composed of transmission and adjustment devices, drums, strippers, cleaners, and controllers. The conventional drum type molding machine currently has four-sided drums, eight-sided drums, and twelve-sided drums. Forming machine for up and down type egg tray production equipment. The up-and-down mobile molding machine moves the mold up and down and sinks into the water tank for suction filtration. The production capacity of the production line is 3-4 times per minute throughout the day. ③Swing is a molding machine for egg tray production equipment
The swing molding machine is the lower template of the lower rotating body sucking and filtering in the slurry tank, and dewatering. At the same time, the upper and lower rotating bodies do the reciprocating swing in place to clamp the upper and lower molds; then the vacuum suction molding is performed, which is characterized by small equipment volume and installation steps Flexible, but the pressure of the molding machine is small, suitable for the production of bulk egg trays, fruit trays and lined packaging products such as loose texture products.
The turning type molding machine is a form in which the forming mold is placed in a slurry tank to be sucked and filtered and then turned to the top to take out the formed wet paper mold blank. The production speed is 3 times/minute. This type of machine is small in size, similar to the up-and-down mobile molding machine, and its production volume is smaller than that of the rotary type. It uses small batch production, long suction time, thick-walled and complex shape industrial buffer packaging paper molded products.

Effect of pulp concentration on product during egg tray production
In the production process of the egg tray machine, the concentration of the slurry directly affects the quality of the product. If the concentration is too low, the strength of the product is low, which easily causes product damage, breakage, and fakes. If the concentration is too high, the weight of the product will be increased, and the materials will be ruined. Both of them will lead to the improvement of the production cost of the product. The manual control of the pulp concentration has poor accuracy and slow response speed, and the automatic control is much better.
The practice shows that this control has a fast response speed and high control accuracy. The product productivity and yield can reach or even exceed the design requirements, fully satisfying the production needs. Although there are ready-made pulp consistency control systems used in the paper industry in China, due to the equipment dispersion in the pulp molding process, the slurry distribution pipeline is longer, and the slurry concentration control in all egg tray systems is more difficult.
Therefore, the multi-point test and multi-point adjustment are used to adjust the slurry concentration. The control process uses the pid algorithm. The concentration change information is sent by the sensor for the measurement of the slurry concentration. The amount of diluted water is controlled by the control computer to output the control response after calculation. You can be satisfied with the control request that changes abruptly, and also with the control request that accumulates the trend.

The egg tray machine is an assembly line work. All links must be synchronized and accurate, and there must be no leaks. This needs to be slowly corrected to meet your ideal requirements. The control system checks regularly to reduce the possibility of hidden dangers.

The egg tray machine requires a machine, electrical integration, high degree of automation in the production process, safe and reliable operation, and the entire process is basically unmanned. Due to the complex process of the egg tray machine production line, the on-site operating environment is relatively humid, and there is a certain degree of equipment Corrosion, many input/output I / O points, and low field failure rate and high reliability are required. According to the process flow and control requirements (mainly in the order of action cycle), a programmable controller can be used instead of a single-chip computer as the core component of the control system.
