Believe that the central feed system manufacturers know that the central feed system has the ability to change the variety of raw materials, multi-color materials used in combination, to achieve the coloring process automation features, while the central feeding system can be fully automatic Recycling and using the nozzle cold material, it can control all of the feeding equipment and prevent the occurrence of blockage in the storage silo, by setting the central monitoring station to achieve full automation, the central feeding system due to accurate measurement, mixing, And the flexibility to change the color, to adapt to the product multi-color variety requirements, it is widely used in many injection molding workshop.
Central feeding system process configuration features:
1, the middle of the material handling system:
the rapid growth of science and technology to the plastic raw materials processing industry has created a broader space for growth, however, as the scope of business continues to expand, the competition is also facing endless relief. How to improve the quality of products, improve production efficiency and reduce various types of consumption is an important decisive point of business growth, in order to meet the demand, Hengrong machinery and equipment research and manufacture of intermediate materials processing plastics, plastic raw materials in the drying, transportation and Storage and other aspects of supply solutions. The design concept is compact, reliable operation, simple maintenance, energy conservation.
2, the central transport system:
the central transport system to accept the vacuum transport method, through the convergence of the piping system to transport plastic materials from the storage tank to the central drying system, and then the dried material transported to each injection molding machine, the system first By the vacuum pump, the middle of the dust filter, suction box, the middle of the sub-stations, transport lines and other components. Intermediate transport system to accept the "one dull one pipe" planning methods to ensure that the entire system is stable, no blocking phenomenon. It cooperates with the center drying system. Drying atmosphere can be used to transport the material to prevent moisture after the resurgence of the material, at the same time in each transport cycle after the transfer line will be liquidated to ensure that there is no residual pipeline particles, to prevent the resurgence of materials also help Improve the quality of molded products.
3, the center of the drying system:
the middle of the drying system adopts the latest Feng Chao dehumidifying dryer, which uses the material for the reliable dry supply of continuous chaos low dew point drying wind, drying management system and many other skills as well as the latest PLC microcomputer Digital controller, PID temperature control system. Closed loop not only saves energy, but also closes the circuit at high temperatures during the regeneration process to ensure that the plastic is transported dry. 1.2 cooler with the characteristics of agile cooling to improve moisture absorption effect wheel dehumidifier, and make the energy to obtain the maximum level of exercise, the internal structure of stainless steel one piece, the tube also has a small loss, the advantages of heating average. Dehumidifier can be washed, long service life. For some materials, drying at high temperature will cause thermal degradation of materials, the use of human intelligent drying management system is through the monitoring of the amount of material used to actively adjust the drying temperature, the lower the amount of material in the context of active low Drying temperature to prevent damage to the material in the process not only save a little heat, but also to ensure the continuity of production, if the material used in the environment to increase rapidly, the system will alarm, warned the material did not get useful drying, Easy to operate.
The above is the configuration of the central feed system process features, in addition, the central feed system uses vacuum transfer mode, through the central pipeline system to transfer plastic raw materials from the storage tank to the central dehumidification drying system, and then the dried feedstock to In each injection molding machine. Ensure that the entire system of air transport of raw materials to prevent moisture desiccant after the resurgence of raw materials, while stable in each transport line.
