What Problems Can the Central Conveying System Solve?

The working principle of the central conveying system lies in the use of vacuum conveying method, and through the centralized pipeline system, the plastic raw materials are conveyed from the storage tank to the central dehumidifying and drying system, and then to each injection molding machine after drying. Its use can prevent the hygroscopicity of the dried raw materials and ensure that the air in the entire system transports the raw materials, thus making it a feeding equipment designed for the production of plastic products in the injection molding workshop. So, what problems can the central conveying system solve? Let’s take a look:

Characteristics of the design of the central conveying system

• The characteristic of the quantitative feeding and loss weight metering feeder determines that the stirring hopper of the central conveying system supplies materials in a batch form. Therefore, every batch feeding of the stirring hopper causes a large fluctuation in the material level. In order to ensure continuous and stable feeding of the system, the material level of the stirring hopper of the central conveying system must be controlled reliably and automatically.

  
  

• The installation height of the central conveying system equipment is reduced, which is easy to maintain. The foreign plan installs most of the equipment such as loss weight metering feeder and stirring hopper at a higher place. The self-designed plan only rises 2-3m off the ground for the loss weight metering feeder, and only 5m for the stirring hopper. The self-designed plan is better and favorable for equipment maintenance.

  
  

• Control the quantitative feeding of the central conveying system. Once the material enters the screw, it is forced to move forward. When conveying tough materials or feeding excessively, the material will have no room to move backward, which may cause overload accidents. When the feeding is insufficient, the output is unstable. Therefore, the feeding of the central conveying system needs to be equipped with additional quantitative feeding devices to strictly control the feeding amount based on the material properties and the size of the extrusion amount.

  
  

• The stirring hopper of the central conveying system adopts the weighing method to measure and control the material level in real-time. The normal state and abnormal state are converted according to the signal of the production line breakage. The stirring hopper sets the high and low level of the material. When the material reaches the high level, the total amount of feed supplied to the stirring hopper will decrease by 5%. Similarly, when the material reaches the low level, the total amount of feed supplied to the stirring hopper increases by 5%. Keep the material level of the stirring hopper fluctuating in this range.

Problems solved by the central conveying system

• Due to the continuous development of society, different workshops require different amounts of materials. The central conveying system can design different optimized installation schemes according to different workshops and different supply materials.

  
  

• The central conveying system can reduce a lot of labor costs, because it is simple to operate, and only a few people can control the entire operation of the injection molding factory. It can also reduce other auxiliary equipment, thus saving the maintenance costs of electricity.

  
  

• The central conveying system has an independent centralized dust collection system, which is more convenient and efficient in cleaning. The environmental protection effect can meet the requirements of dust-free operation standard, and it can also reduce noise, which can greatly reduce the pollution level of the injection molding factory, maintain the cleanliness of the production workshop, and establish the image of modern factory management.

  
  

• The central conveying system can realize automatic supply of multiple materials for multiple injection molding machine equipment. Here, it can complete multiple tasks, such as material color matching, drying treatment, and proportionate crushing, and recycling of materials. At the same time, it can achieve high degree of automation control and monitoring, and meet the production needs of the workshop, improving operating efficiency.

Through the above introduction, we all know that the central conveying system can solve many feeding problems, so its role in the production of plastic products in the workshop cannot be ignored.
