What is the difference between central and automatic feeding system?

Source: Popularity:2644 Publication time:2017-11-23 11:26:08 smallmiddlebig

In recent years, the continuous development of injection molding and processing industry, the growing demand for injection molded products in various industries is also increasing, thereby pushing the development and improvement of the entire injection molding and molding technology standards. However, due to the complicated equipment and personnel in the injection molding industry, Job management is often unable to cope with such a complex situation, resulting in poor management of processing materials and processing costs.


This requires the application of a feed system that meets the multi-color, multi-product requirements of the product. The central feeding system can change the variety of raw materials and the combination of multi-color materials as needed to achieve the central feeding system of the coloring process. So we all know the central feeding system and automatic feeding system What is the difference? Last Xiaobian for everyone to share the benefits of using the central feeding system, today we come to introduce the central feeding system and automatic feeding system the difference.

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

First, the working principle:


The working principle of the central feeding system is to adopt the vacuum transmission mode, and then convey the plastic raw materials from the storage tank to the central dehumidification drying system through the centralized pipeline system, and then transfer the dried raw materials to each injection molding machine. It is used in conjunction with the central dehumidification drying system can be used after dehumidifying drying delivery line will be cleaned up to ensure that there is no residual pellets in the pipeline to prevent the resurgence of raw materials while also ensuring the raw material into the injection molding machine performance Consistent. Under the action of vacuum negative pressure, the original dust in the raw material is filtered through the dust filtration system to ensure that the air of the whole system is transported to the raw material, which helps to improve the quality of the molded product. At the same time in each transport line of stability, no blocking phenomenon occurred.

Automatic feeding system works, the vacuum tube is turned off, start the motor, with a low vacuum flow of plastic resin particles into the vacuum tube, the motor stalls, and then the particles into the hopper, so the cycle. In the design of the control system, you can use a motor control two feeding production line, the directional valve switch. Both production lines can be run separately or simultaneously. If the two are running at the same time, when the delivery of a production line is completed, it is judged that the discharge of the other production line has been completed. Then, the motor is continuously switched and the directional valve is reversed, thereby feeding the other production line. This will allow you to control the efficiency of the system and the motor for automatic feeding.

Second, the composition:


The central feeding system is composed of central console, cyclone dust collector, high-performance filter, fan, selection rack, branch station, drying hopper, dehumidifier, fretting hopper, electric eye hopper, Composed of various components.

Automatic feeding system components, power part, also called vacuum station; dust removal device part, the common dual dust combination, automatic dust removal; material distribution station, also known as material station; suction bucket, also known as suction bucket , Sub-vacuum and electric eye hopper; delivery pipeline; vacuum pipeline; central console; protection device.

Third, characteristics:

The central feeding system enables the automatic feeding of a wide range of raw materials to any multi-chamber injection molding machine. This includes the drying of raw materials, the color matching process, and the use of screened recycling materials, enabling a high degree of automation, Monitoring, etc., and can meet the 24-hour non-stop production needs. At the same time, the central feeding system is easy to operate, requiring only a few people to control the feeding requirements of the entire injection molding plant, thus reducing the labor costs. It can be done using different users, different plant characteristics, different requirements of raw materials. Can be designed according to the actual needs of a reasonable solution.

The use of automatic feeding system to ensure stable operation of the entire system, no plastic resurgence, plugging phenomenon occurs. It is used in conjunction with a central dryer (dehumidifier) system to allow dry air to re-dry the material to prevent moisture from drying out and to clean the tubing after each delivery cycle to ensure there is no residue in the tubing. While avoiding the resurgence of raw materials, it also ensures the consistency of raw materials in the injection molding machine. Under the same effect of vacuum negative pressure, the original dust in the raw materials is filtered out through the filter (dust collector) system, which is beneficial to improve the product quality.
