u7cc彩票The operation principle of the central centralized feeding system is to select the vacuum transmission method, then transport the plastic materials from the storage tank to the central dehumidification and drying system through the centralized pipeline system, and then transport the dry materials to each injection molding machine. The dehumidification and drying system of the cooperation center can be used. After the dehumidification and drying feeding cycle, the transportation pipeline will be sorted to ensure that there is no residual granular material in the pipeline. Together with preventing the moisture return of the material, it also ensures the common function of the material in the injection molding machine. Under the effect of vacuum and negative pressure, the original dust in the material will be filtered out through the dust filtration system to ensure that the air of all systems can transport the material, which is helpful to improve the quality of formed goods. Together, the operation of each conveyor is stable, and there is no scene of material blockage.

The operation principle of the automatic centralized feeding system is to close the vacuum pipe, start the motor, send the plastic resin particles into the vacuum pipe with low true air flow, stop the motor, and then discharge the particles into the hopper. In the planned control system, one motor can be used to control two feeding production lines, which can be switched by the directional valve. The two production lines can operate alone or together. Assuming that the two operate together, when one production line is transported, it is judged that the discharge of the other production line has been completed, then the motor continues to turn to the direction valve to reverse, and then feed the other production line. This can show the power of the control system and motor, and then complete the active feeding.

The central centralized feeding system is composed of central console, cyclone dust collector, high-efficiency filter, fan, material selection rack, branch station, drying hopper, dehumidifier, micro hopper, electric eye hopper, material cut-off valve, air cut-off valve and other components.

The components of the automatic centralized feeding system include power, also known as vacuum station; For some dust removal equipment, the contact method of two-layer dust removal is generally selected to actively remove dust; Material distribution station, also known as material selection station; Suction bucket, also known as suction hopper, is divided into vacuum hopper and electric eye hopper; Delivery pipeline; Vacuum pipeline; Central console; Protection equipment.

The central centralized material supply system can actively supply a variety of materials to any injection molding equipment in multiple rooms, which can include the boring treatment of materials, color matching treatment, and the use of damaged and recovered materials according to the share. It can implement a high degree of active control and monitoring, and meet the production needs of 24-hour continuous machine. The central centralized feeding system is easy to operate. Only a few people are needed to control the feeding needs of all injection molding plants, and then a lot of labor costs are reduced. It can achieve different users, different workshop characteristics and different material application requirements. Can plan the optimal scheme according to the needs of practice.

The application of automatic centralized feeding system can ensure the safe and stable operation of the whole system, and there is no plastic moisture regain and material blockage. The application of the drying machine (dehumidifier) system in the cooperation center can make the dry air dry the material again, prevent the plastic moisture from returning after drying, and sort out the delivery pipe after each delivery cycle to ensure that there is no residue in the pipeline. In order to prevent the moisture regain of the material, the commonality of the material in the injection molding machine is also guaranteed. Under the effect of vacuum negative pressure and feeding, the original dust in the material is filtered out through the filter (dust collector) system, which is conducive to improving the quality of goods.
