Os princípios de trabalho de diferentes tipos de alimentadores são diferentes . abaixo, apresentaremos os princípios de funcionamento dos alimentadores de vácuo comuns e pequenos alimentadores de mola:
Alimentador de vácuo
Princípios básicos
In the vacuum feeder system, when the vacuum pump is working, its inlet pipe forms a negative pressure airflow, and the material is transported from the inlet to the gas separator by the negative pressure airflow. Clean air returns to the atmosphere through the filter element. This method of using negative pressure airflow to transport materials is the basic working principle of a vacuum feeder.
Processo de transporte
Powder industry application: The conveying hopper (feeding bucket) is usually a conical shape with a filtering device and a back blowing device inside. The feeding bucket carries the product into it through the transfer pipe. When the bucket is in an overflow state, the vacuum pump automatically releases it through a pre-set program, and the material falls down from the discharge valve due to gravity. Depois que o balde de material estiver vazio, a bomba de vácuo funciona automaticamente através de um programa predefinido, a válvula de descarga fecha o balde de material e o balde de material retorna ao estado de vácuo, iniciando o próximo ciclo .
Injection molding application: When there is a shortage of material in the material bucket of the injection molding machine, a signal will be automatically transmitted to the suction machine. The suction machine uses the principle of exhaust to transport plastic raw materials into the material bucket of the injection molding machine. When the material reaches a certain level, the suction machine will stop working, and it will be transported again when the material is not Chega .
Relação entre transporte material e características
The fluidity of materials has a significant impact on transportation, and can be determined by the stacking angle. The smaller the angle between the conical surface formed when the material slides from a fixed height and comes to a complete stop and the horizontal plane, the better the flowability of the material, and it will be more convenient and efficient to pass through the filtering device during transportation. However, for damp and viscous Os materiais, o peso do material aumenta devido à presença de umidade, dificultando o alimentador para sugá -los para a tremonha ., mesmo que sejam sugados, eles ainda podem aderir ao elemento de filtro durante a filtração, resultando na incapacidade de continuar o processo de transmissão.}}}
Pequena máquina de alimentação de mola
The small spring feeding machine is an automated production equipment mainly used to automatically feed small springs into the production device. Its working principle is to remove the spring from the tray through the transmission system, then position it at the feeding port, and at the feeding port, use a mechanical arm or other mechanism to clamp it and send it to the next device for processing or storage.
