Shuliy - Model SL - Effect of pulp concentration on product during egg tray production

    In the production process of the Shuliy 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 damage, breakage, and the occurrence of fake goods. If the concentration is too high, the weight of the product will be increased, and the material will be ruined. Both of them will lead to the improvement of the production cost of the product. When the concentration of the slurry is manually controlled, the accuracy is poor, the response speed is slow, and the automatic control is much better.

    Actually, this control has a fast response speed, high control accuracy, product productivity, and yield can reach or exceed design requirements, and complete satisfactory production needs. Although there is a pulp concentration control system used in the ready-made papermaking industry in China, due to the loosening of the equipment in the pulp molding production process, the slurry conveying pipeline is long, making it difficult to control the concentration of the slurry in all egg tray systems.

    Therefore, the multi-point test and multi-point adjustment method are used to adjust the slurry concentration. The control process adopts the pid algorithm, and the concentration change information is sent from the sensor for measuring the concentration of the slurry, and the amount of the diluted water is controlled by the control amount of the output response calculated by the control computer. The control request that is abruptly changed can be satisfied, and the control request of the cumulative trend is satisfied.

    The egg tray machine belongs to the assembly line. All the links should be synchronized and accurate, and there should be no leakage. 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, a high degree of automation in the production process, safe and reliable operation, and the whole process basically realizes unmanned operation. Due to the complicated process of the egg tray machine production line, the operating environment on the site is relatively humid, and the equipment has certain equipment. Corrosion, input, and output I / O points are large and require low field failure rate and high reliability. According to the process flow and control requirements (action sequence cycle is the main), the programmable controller can be used instead of the single-chip as the core component of the control system.
