Centralized feeding system


Centralized feeding system

So how to maintain a centralized feed system
The In order to allow the powder automatic batching system to work long-term stable, the need for customers to the equipment of the conventional centralized feeding system
Maintenance, centralized feeding system
Generally divided into four areas.

Centralized feeding system maintenance and maintenance of the first, year maintenance
Annual maintenance of the central feeding system equipment, the best use of holidays on the equipment comprehensive maintenance, replacement of wearing parts.
In order to improve the utilization of equipment, equipment, normal operation, can not do without the normal maintenance of the equipment.

Centralized feeding system maintenance and maintenance of the second and quarterly maintenance
The maintenance of each quarter, such as the temperature rise of the fan in the vacuum station, the tightening of the piping, the case of the corners, the case of the compressed air hoses, the cylinders, the solenoid valve, the transparent hose The situation and so on.

Centralized feeding system maintenance and maintenance of the third, month maintenance
Monthly regular inspection of the centralized feeding system equipment, such as the airtightness of the pipe connector, the filter cleaning of the dust removal device, the inspection of the seals, the inspection of the interceptor valve and the shut-off valve, the inspection of the electrical part, etc. The

Centralized feeding system maintenance and maintenance Fourth, the daily maintenance
The main equipment of the centralized feeding system is responsible for carrying out the work of the shift, observing its operation, registering and handing over, such as the setting of the central console, the running sound of the vacuum station, the dust handling of the dust removal device, The transport of raw materials is smooth, whether the compressed air in the normal range, whether the lack of material and so on.
Centralized feeding system
The composition of the central console, cyclone dust collector, high efficiency filter, fan, branch station, drying hopper, dehumidifier, election material rack, micro-hopper, electric eye hopper, cut off the valve, cut off the valve.

The central feed system is designed for the production of plastic products in the injection molding plant, enabling uninterrupted unmanned continuous molding operations. According to the need to change the variety of raw materials, multi-color materials, the combination of use, to achieve the color process automation. The system is able to regenerate and use the sprinkler in a fully automatic manner, to control all the feeding equipment and to prevent the occurrence of congestion in the storage bin, and to achieve full automation by setting the central control station.
The working principle of the centralized feeding system
The centralized feed system uses vacuum transport to transport the plastic feedstock from the storage tank to the central dehumidification drying system through a centralized piping system and then transport the dried raw material to each injection molding machine. Central feeding system using "a machine a tube" design, to ensure that the entire system of air to transport raw materials to prevent dehumidification after drying raw materials resurgence. At the same time in each transport line is stable, no blocking material phenomenon occurred. It is used in conjunction with the central dehumidification drying system. It can be used to clean the conveyor line after dehumidification and drying. Ensure that no residual pellets are in the pipeline. In order to avoid the resurgence of the raw materials, it also ensures the performance of the raw materials Consistent. In the vacuum under the action of raw materials in the original dust will be filtered through the dust filter system, help to improve the quality of molding products.
Fast feeding station (sub-Qi station) Features:
The branching station is made up of several branches, and the same raw material for the sub-bleed pipe can be used for the injection molding machine machine, each with quick head tightness; can improve the system efficiency, easy to change material.
Centralized Supply System Built-in Introduction Central Console Features:
1, the addition of raw material control screen, the monitoring of the use of raw materials, suction, lack of material and the central host (motor) a variety of anomalies.
2, with the material tube pumping clear tube, automatic dust collection center for the host A, B alternating automatic switching and artificial selection of material error-proof function;
3, the use of PLC and large size 10.4-inch color man-machine interface touch panel, easy to understand, good operation;
4, color display in a variety of settings, operation and operation of the situation;
D'Aantai Central Supply Host Features:
1, the motor does not stop the design, in order to avoid frequent motor start, resulting in wear and tear;
2, with safety relief valve, when the host movement pressure is too large, the safety set value overload, release valve fully release pressure to protect the motor;
3, for the host two A, B alternately, and there are automatic switching valve design to ensure that the stability of raw materials delivery.
Automatic reversal whirlpool dust collector Features:
1, dust collector installed wind pump, can be effective in the non-stop, mobile dust collector dust.
2, can be attached to high pressure gas tank, automatic cleaning filter;
3, the air filter and cyclone dust collector design, natural centrifugal force to collect dust and dust;
The characteristics of the centralized feeding system First, the modern factory image: Centralized feed system will make raw materials and dust on the injection molding production to minimize the level of pollution, which can maintain a clean production workshop, and the central feeding system unique focus on dust recovery System, clean more convenient, environmental protection effect is to reach 100,000 clean room operating requirements standards, and reduce noise, and ultimately can achieve unmanned automated production workshop, and establish a modern factory management image.
Second, the personalized: centralized feeding system can be used to different users, different workshop characteristics, different requirements of the use of raw materials. Can be designed according to the actual needs of the optimal solution.
Third, energy: In addition, due to the use of a centralized feeding system, the corresponding reduction in a lot of stand-alone equipment, also saves energy and reduce maintenance costs. The feeding system is easy to operate, requiring only a few people to control the supply needs of the entire injection molding plant, thus reducing the large amount of labor costs. Second, the reduction in the injection molding machine next to the raw material and the corresponding auxiliary equipment, improve the utilization of space.
Fourth, the efficient: centralized feeding system can be achieved by a variety of raw materials automatically supply multi-chamber arbitrary injection molding equipment used, which may include the drying of raw materials, color processing, and the proportion of the use of crushed recycled materials, to implement the height Of the automation control, monitoring, etc., and to meet the 24-hour non-stop production needs.
Centralized feed system design process raw materials → storage → measurement → drying → transportation → use
Daan Tai feeding system to avoid the return of raw materials at the same time also ensure that the injection molding machine in the consistency of raw materials, in the vacuum negative pressure with the role of the original raw materials in the dust through the filter (dust collector) system filter out, quality. With the central dryer (dehumidifier) system, dry air can be used to dry the raw materials again to prevent the plastic moisture after drying, while in each conveying cycle after the pipeline to clean up to ensure that there is no residue in the pipeline. Using a machine a tube, sealed circuit design, to ensure the stability of the entire system, no plastic resurgence, blocking material phenomenon occurred.
