Central material conveying system working principle
we can plan for you from the auxiliary equipment of the entire plastic molding plant, including plastic raw material storage, drying and transportation to metering and mixing, from mold temperature control to molding equipment cooling systems, from automated manipulators to waste recycling, from The film air ring is cooled to online thickness measurement.
Storage and transportation
No matter a small storage barrel or a large outdoor storage silo, we can provide you with the most suitable storage solution to save space, protect raw materials, and reduce transportation costs.
The parts in contact with the raw materials are made of stainless steel and the filter device of the conveying system, which effectively ensures that the raw materials are not polluted during the conveying process. The flexible conveying air supply adjustment system, by adjusting the conveying speed, effectively avoids the situation of drawing or dusting of the raw materials due to different conveying conditions.
For the transportation system of high-temperature raw materials, we has specially designed a solution with water cooling function, which reduces the risk of high-temperature raw materials transportation by the vacuum pump.
The closed-loop secondary conveying system, our process of conveying the hot material and the heat preservation hopper that needs to be sent to the molding machine after drying, can greatly reduce the heat loss during the conveying process and the moisture absorption of the dried material again. risk.
Raw material distribution
The standard manual material distribution station uses quick connectors, allowing you to choose the best batching pipeline. The central distributor and its matching connectors can improve the efficiency of the system. The automatic material distribution station is controlled by a central console and can be used for large-scale feeding systems.
Dosing and mixing
Volumetric Masterbatch Machine SCM can be used for the measurement of masterbatch raw materials, and the production range is 0.2~32kg/hr. If the customer has higher requirements on the proportion and accuracy of the color masterbatch, we recommend using the weightless masterbatch machine SGD, adopting the weightlessness measurement method, and the production range is 0.04~32kg/hr.
The SGB controller of the weighing mixer is equipped with an Ethernet interface, and the corresponding software can read the raw material ratio data (such as maximum output, actual output, and ratio accuracy) through this communication interface to facilitate product quality control. The automatic repeat calibration function will automatically calibrate the program after each load to ensure the best proportioning accuracy. It has the function of automatic compensation for recycled materials, which can automatically calculate color difference compensation according to the amount of recycled materials.
Dehumidification and drying
In the plastic molding process, drying becomes a particularly critical stage. It is necessary to ensure that the moisture in the raw materials is removed and the drying temperature is reasonable. the desiccant dryers can provide dry air with a dew point of -40°C or lower, and can monitor various parameters in time and ensure a constant dew point.
Dew point setting and smart regeneration function, the dew point temperature of traditional dehumidifiers cannot be set, and the dehumidifiers are working at maximum load. But when processing raw materials has high requirements for humidity, the dew point must be set and controlled. The dew point temperature can be set related to the control of regenerative energy, which reduces energy consumption compared with traditional dehumidifiers.
