The difference between the central feeding system and the automatic feeding system

2018-05-07
First, the working principle:
The working principle of the central feeding system is to use vacuum transfer method, and then the plastic raw materials are sent from the storage tank to the central dehumidifying and drying system through a centralized piping system, and then the dried raw materials are delivered to each injection molding machine. It cooperates with the central dehumidifying and drying system, and can use the dehumidifying and drying to send the circulation to clean the pipeline to ensure that there are no residual pellets in the pipeline. While preventing the raw materials from resurgence, it also ensures the performance of the raw materials added into the injection molding machine. Consistent. Under the vacuum negative pressure, the original dust in the raw material will be filtered out through the dust filtration system to ensure that the air in the whole system is transported to the raw material, which helps to improve the quality of the molded product. At the same time, the operation of each transmission is stable, and no blocking phenomenon occurs.
The
The working principle of the automatic feeding system is that the vacuum tube is closed, the motor is started, the plastic resin particles are sent into the vacuum tube with a low vacuum air flow, the motor is stopped, and the particles are discharged into the hopper, and so on. In the design of the control system, one motor can be used to control two feeding lines and switched by the directional valve. Both production lines can be operated individually or simultaneously. If both operate at the same time, when the end of a production line transmission, it is determined that the discharge of another production line has been completed, then the motor will not stop and the directional valve commutation, so as to feed another production line. In this way, the efficiency of the control system and the motor can be utilized to achieve automatic feeding.
The
Second, composition:
The
The central feed system consists of a central console, a cyclone dust collector, a high-efficiency filter, a fan, a material rack, a branch station, a drying hopper, a dehumidifier, a micro-moving hopper, an electric eye hopper, a cutting valve, and an air trap valve. Each part consists of.
The
The components of the automatic feeding system are: the power part, also called the vacuum station; the dust removal apparatus part, generally adopts the dual dust-removing combination method, and the automatic dust removal; the raw material distribution station, also called the material selection station; the suction material bucket, also called the suction hopper , Sub-vacuum and electric-eye hoppers; transfer lines; vacuum lines; central consoles;
The
Third, characteristics:
The
The central material supply system can realize the automatic supply of multiple raw materials to any multi-room injection molding processing equipment. This can include the raw material drying treatment, color matching treatment, and the use of proportioned crushed recyclable materials, enabling highly automated control. Monitoring, etc., and can meet the production needs of 24 hours without shutdown. At the same time, the central feeding system is easy to operate, requiring only a few individuals to control the feed requirements of the entire injection molding plant, thereby reducing a lot of labor costs. It can do different users, different workshop features, and different raw material usage requirements. You can design the optimal solution according to the actual needs.
The
The use of automatic feeding system can ensure the stability of the entire system, and no plastic regain or blocking occurs. It is used with a central dryer (dehumidifier) system to allow the dry air to dry the raw materials again to prevent the dried plastics from returning moisture. At the same time, the transfer tubes are cleaned after each transfer cycle to ensure that there are no residual materials in the pipes. In order to prevent the raw materials from returning moisture, it is also ensured that the consistency of raw materials in the injection molding machine is added. Under the action of the vacuum negative pressure, the original dust in the raw materials is filtered out by the filter (dust collector) system, which will improve the product quality.
