Centralized conveying system for raw materials in injection molding workshop

Plastic centralized feeding system in injection molding workshopfeature
The centralized control console can control one vacuum pump and multiple vacuum pumps to load the injection molding machine simultaneously, and can also monitor the external signals, working status, and possible faults of the system in real time. The visual touch screen human-machine interface is easy to operate and powerful, greatly improving the automation level of the system and saving energy. Centralized control can set different parameters and can be directly monitored on the touchscreen screen. Single machine control cannot be controlled in the same place, and the operation time is too long and the efficiency is low when starting up
The centralized control of the plastic feeding system in the injection molding workshop can achieve remote control operation, and one vacuum pump can feed multiple machinesDifference between centralized feeding and standalone operation
There are 10 injection molding machines that need to be fed, and with centralized control, one vacuum pump can be configured. For a single machine, 10 machines are requiredPowder suction machineEnergy consumption is greater than centralized control and cannot be operated in the same place.
The venue used for the system is different from that of a standalone machine. The centralized storage or stacking of raw materials, centralized collection of dust, and distance from the site have significantly improved the working conditions near the main unit, thereby enhancing the clean and tidy production environment in the workshop and ensuring that raw materials are not contaminated. A single machine requires more space to place raw materials, and the placement of raw materials is chaotic, making it easy to make mistakes when adding materials, and dust cannot be collected centrally. The centralized feeding system can reduce the amount of material added by workers, eliminate the need for manual handling of raw materials, and lower labor intensity.
Used for raw material transportation in injection molding, it can automatically feed materials to the injection molding machine. When there is a shortage of material in the material bucket of the plastic central feeding system, it will give a signal to the powder suction machine. The powder 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 powder suction machine stops and can be transported again when the material is insufficient.
