Difference between central feeding system and automatic feeding system

The working principle of the central feeding system is to select the vacuum conveying mode, and then transfer the materials from the storage tank to the dehumidification drying system in the middle through the header system, and then send the materials to the injection molding machines through the header system. The conveying pipeline can be cleaned after the dehumidification and drying circulation to ensure that there is no residual granular material in the pipeline, which not only prevents the moisture regain of the material, but also ensures the versatility of the injection molding machine material. With vacuum negative pressure, the dust in the material will be filtered out through the dust filtration system, which ensures the air transportation of the whole system, and is conducive to improving the quality of the formed goods. Each time the gas transmission runs smoothly, and there is no blocking phenomenon.

The working principle of the automatic feeding system is: after the vacuum tube is closed, start the motor, inject plastic resin particles into the vacuum tube, and then send the particles into the vacuum tube with low vacuum air flow, and then discharge the particles into the hopper, and so on. In the planned control system, one motor can be used to control the two feeding production lines and switch through the direction valve. The two production lines can operate separately or simultaneously. Assuming that the two production lines are running at the same time, when one production line has finished conveying and it is judged that the discharging of the other production line has been completed, the motor will continuously turn to the direction valve for reversing, and then transport for the other production line. This can show the control system and motor power, and then complete the active feeding.

The central feeding system is composed of central console, cyclone collector, high filter, fan, material selection rack, branch station, dry hopper, dehumidifier, micro hopper, eye hopper, cut-off valve, cut-off valve, etc.

The components of the automatic feeding system include the power part, also known as the vacuum station; For some dust removal equipment, the method of two-layer dust removal is generally adopted, that is, active dust removal; Material distribution station, also called material selection station; Suction bucket, also known as dust removal device; Vacuum tube; Central console;

The central feeding system can actively supply multiple materials and use any injection processing equipment in multiple rooms. In this process, it can include the drying treatment of materials, color matching treatment, and the use of recycled materials in proportion. It can implement highly active manipulation, monitoring, etc., and can meet the production needs of 24-hour continuous machine. A centralized feeding system is easy to operate, and only a few people can control the raw material supply demand of the entire injection molding plant, thus greatly reducing a large number of labor costs. In this way, different application users, different workshop characteristics and different material application requirements can be achieved. Can design a better scheme according to actual needs.

The central feeding system is adopted to ensure the smooth operation of the whole system without moisture regain and material blocking. The coupling dryer (dehumidifier) system is used to dry the material again after drying to prevent the moisture regain of the plastic after drying. After each delivery, the conveying pipe is sorted together to ensure that there is no residue in the pipe. At the same time, the prevention of material moisture also ensures the commonality with the injection molding machine material. Under the same direction of vacuum negative pressure, the original dust in the material is filtered out through the filter screen (dust collector) system, which is beneficial to the product quality.
