What are the differences between central feeding system and automatic feeding system? In recent years, with the continuous development of the injection molding industry, the increasing demand for injection molding products in various industries has also increased, which has promoted the development and improvement of the whole injection molding and molding technology level. However, due to the complex situation of equipment and personnel in the injection molding industry, the traditional manual operation 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 feeding system that meets the requirements of multi color and multi variety of products. The feeding system has a central feeding system and an automatic feeding system. What are the differences between the central feeding system and the automatic feeding system? Next, I'll explain to you.

First, the difference between the working principle of central feeding system and automatic feeding system:

The working principle of the central feeding system is to adopt the vacuum transmission mode, then transport the plastic raw materials from the storage tank to the central dehumidification and drying system through the centralized pipeline system, and then transport the dried raw materials to each injection molding machine. It is used in conjunction with the central dehumidification and drying system. Dehumidification and drying can be used. After circulation, the transmission pipeline will be cleaned to ensure that there is no residual granular material in the pipeline. While avoiding the moisture regain of raw materials, it also ensures the consistency of the performance of raw materials added to the injection molding machine. Under the action of vacuum and negative pressure, the original dust in the raw materials will be filtered out through the dust filtration system to ensure that the air of the whole system transports the raw materials, which is helpful to improve the quality of formed products. At the same time, the operation of each transmission is stable and there is no material blockage.

The working principle of the automatic 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 designed control system, one motor can be used to control two feeding production lines, which are switched by the directional valve. The two production lines can operate independently or simultaneously. If the two operate at the same time, when the conveying of one production line is completed, it is judged that the discharge of the other production line has been completed, then the motor keeps turning to the direction valve to reverse, so as to feed the other production line. In this way, the efficiency of the control system and motor can be brought into play, so as to realize automatic feeding.

Second, the difference between the composition of central feeding system and automatic feeding system:

The central 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 feeding system are the power part, also known as the vacuum station; The dust removal device generally adopts the combination of double dust removal and automatic dust removal; Raw material distribution station, also known as material selection station; Suction bucket, also known as suction hopper, is divided into vacuum and electric eye hopper, conveying pipeline, vacuum pipeline, central console and protection device.

Third, the central feeding system and automatic feeding system have different characteristics:

The central feeding system can automatically supply a variety of raw materials to any injection molding equipment in multiple rooms, including drying treatment, color matching treatment and proportional crushing and recycling of raw materials. It can implement a high degree of automatic control and monitoring, and meet the production needs of 24-hour non-stop. At the same time, the central feeding system is easy to operate, and only a few people can control the feeding demand of the whole injection molding plant, thus reducing a lot of labor costs. It can meet the requirements of different users, different workshop characteristics and different raw materials. Can design the optimal scheme according to the actual needs.

The use of automatic feeding system can ensure the stable operation of the whole system without plastic moisture regain and material blockage. It is used in conjunction with the dehumidification and drying system to dry the raw materials again with dry air to prevent the moisture regain of the dried plastic. At the same time, the conveying pipe is cleaned after each conveying cycle to ensure that there is no residue in the pipe. While avoiding the moisture regain of raw materials, it also ensures the consistency of raw materials added to the injection molding machine. Under the action of vacuum and negative pressure, the original dust in the raw materials is filtered out through the filter (dust collector) system, which is conducive to improving the product quality.

The above differences between the central feeding system and the automatic feeding system can be summarized here. Using the central feeding system can better improve the production efficiency, and a special person is responsible for the management of raw materials to reduce waste; I hope the above sharing is helpful to you.
