I. Operating Principles:
The operation principle of the central feeding system is to select the vacuum transmission method, then transport the plastic material from the storage tank to the central dehumidification and dryness system through the centralized pipeline system, and then transport the dry material to each injection molding machine. It cooperates with the central dehumidification and dryness system, which can use the dehumidification and dryness delivery cycle to arrange the transportation pipeline, to ensure that there is no surplus granular material in the pipeline, to prevent material moisture back together, but also to ensure the common function of materials in the injection molding machine. Under the vacuum negative pressure effect, the dust from the material Cathaysia will be filtered out through the dust filtration system to ensure that the air of the whole system carries the material, which is helpful to improve the quality of the formed products. Together in each transport operation is stable, no blocking phenomenon occurs.
The working principle of the fully automatic feeder is to close the vacuum tube, start the motor, send the plastic resin particles into the vacuum tube with low vacuum airflow, stop the motor, and then discharge the particles into the hopper, so as to circulate. In the planned control system, one motor can be used to control two feeding production lines, which are switched by the direction valve. The two production lines can operate either alone or together. Assuming that both of them work together, when one production line has been transported, it can be judged that the discharge of another production line has been completed, then the motor continuously turns to the direction valve to change direction, and then feeds for another production line. In this way, the power of the control system and the motor can be brought into play, and then the active feeding can be completed.
Fully automatic feeder
The central feeding system is composed of central console, cyclone dust collector, high efficiency filter, fan, material selection frame, branch station, dry hopper, dehumidifier, micro-motion hopper, electric eye hopper, shutoff valve and other components.
The components of the fully automatic feeder are: power part, also called vacuum station; dust removal equipment part, generally choose the combination method of two-layer dust removal, active dust removal; material distribution station, also known as material selection station; suction bucket, also known as suction hopper, vacuum and electric eye hopper; delivery pipeline; vacuum pipeline; central console; protection equipment.
The central feeding system can be used to supply various materials to multi-room and arbitrary injection processing equipment actively. During this period, it can include the dry treatment of materials, color matching treatment, and the utilization of crushing and recycling materials according to share. It can implement highly active control, monitoring and so on, and can meet the production needs of 24-hour continuous machine. A central feeding system is easy to operate, only a few people are needed to control the supply demand of the entire injection plant, and then a lot of labor costs are reduced. It can achieve different users, different workshop characteristics, different material application requirements. They can plan the optimal plan according to the need of practice.
The application of automatic feeding machine can ensure the stability of the whole system, and there is no plastic moisture regain or blocking phenomenon. It cooperates with the center dryer (dehumidifier) system, which can make dry air dry again on the material, prevent dry plastic moisture regain, together with each transport cycle after finishing the transport pipe, to ensure that there is no residue in the pipeline. In order to prevent material moisture return together and ensure the commonality of materials in the injection moulding machine, under the effect of vacuum negative pressure, some dust of materials in Cathaysia can be filtered out through the filter (dust collector) system, which is conducive to improving product quality.
