Automatic central feed system integration
The whole plant automation program terminal unit Central hopper is the whole system of the terminal equipment; two proportional valve with the main crusher to meet the forming machine for new materials and materials used in combination of special requirements.

Automatic central feeding system integration can be the perfect realization of raw materials dehumidification, drying, transportation, measurement, mixing and other special requirements. Central feeding system has a variety of monitoring and protection functions, work safe and reliable, is the enterprise to achieve the core premise of unmanned chemical plant. The use of industrial computers automatically on all machines for centralized control, to achieve all the materials unit 24 hours continuous feeding operations. With the system within the special features of the machine.
Why did the program choose D'Aetta Central Feeding System?

To achieve the whole plant feeding unmanned operations for enterprises to save a lot of manpower.

With the cooling water circulation system, automatic removal of transmission system, hot and cold exchange system and sub-material recovery system to achieve the whole plant unmanned operations, enterprises can save for air conditioning and lighting equipment and other energy consumption.

Greatly improve the production efficiency of enterprises, reduce production costs.

Greatly improve the quality of products, reduce the non-performing rate.

Can be adjusted according to the need for different raw materials for enterprises to save a lot of trouble.

Pipeline does not occupy the ground space for enterprises to save a lot of effective space.

Walking and placing beautiful, can effectively improve the production workshop environment.

The cost is relatively low, long-term view for the enterprise to save a lot of money. Control unit Central feeding control part is mainly responsible for receiving the signal issued by the various units of work, after the operation issued by the relevant instructions to the implementation of the unit, is the central feeding system of the brain, determine the stability of the entire system and success.
Central feed control box using Siemens PLC and man-machine, the system is safe and stable operation of the premise of protection.

Power unit power part mainly includes vacuum motor and safety filter dust collector, electronic relief valve and mechanical relief valve and other components, responsible for the entire system to provide sufficient power, with the system to complete the pumping work is the whole system Power source.
Central feed system
The central feeding system is based on the customer site machine placement and the use of raw materials on the scene of the situation, combined with the unique auxiliary equipment designed to achieve a centralized supply, centralized control, in order to achieve the whole plant unmanned Intermittent forming operations as a whole solution.

Automatic central feed system integration
To achieve closed pipeline transport of raw materials, to completely avoid the noise of the workshop, dust, hot air pollution, is to maximize the best product quality system.

Automatic central feed system integration

The conveying unit of the conveying unit mainly comprises the function of sucking the material box, the material feeding box, the material selecting station, the field pipeline and the secondary discharge valve, etc. The function of the sucking box is to cooperate with the system to feed the raw material from the dryer or the raw material to the suction Machine, caliber according to the system. The function of the broken material suction box is to cooperate with the system and have the cleaning function, so as to prevent the residual material in the pipeline. The use of anti-static tube clip, effectively eliminate static electricity.

Raw materials include dryers and dehumidifiers, storage tanks. Through the dehumidification drying process to meet the special requirements of raw materials, reduce product non-performing rate, improve product quality, and can effectively shorten the product molding cycle.

Automatic central feed system integration
Automatic central feeding system integrated maintenance is generally divided into four areas.
First, daily maintenance
Automatic central feeding system of the main equipment to achieve the person responsible for the transfer of the observation, record their operation, do a good job registration and transfer, such as the central console parameter settings, the operation of the vacuum station, dust removal device dust treatment , Whether the transport of raw materials is smooth, whether the normal range of compressed air, whether the lack of material and so on.
Second, month maintenance
Monthly regular inspection of the automatic central feeding system, 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
Third, 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.
Fourth, the year of maintenance
Each year the automatic central feeding system equipment, to conduct a comprehensive maintenance, 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.
