The injection molding industry has also made a great contribution. The plastics in the injection molding workshop cannot be separated from the existence of a central feeding system. The central feeding system adopts a microcomputer centralized automatic control to realize a 24-hour continuous feeding operation of pellets. The central feeding system can meet different users, different workshop characteristics, and different raw material usage requirements. Next, the technicians of Dongguan Hengrong Machinery Co., Ltd. will talk about the complete solution of the central feeding system:
Central feeding system
1. Storage and transportation
Regardless of small storage barrels or large outdoor storage silos, we can provide you with the most suitable storage solutions 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, Shini has specially designed a solution with water cooling function, which reduces the risk of high-temperature raw material transportation by the vacuum pump.
The closed cycle secondary conveying system can greatly reduce the risk of heat loss during the conveying process and the risk of moisture absorption by the dried material during the conveying process of the hot material and the heat preservation hopper that needs to be sent to the molding machine after drying.
2, 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.
3, metering and mixing
Volumetric masterbatch machine can be used for the metering of masterbatch raw materials, and the production range is 0.2~32kg/hr. If the customer has higher requirements for the addition ratio and accuracy of the color masterbatch, we recommend the use of a weighing color masterbatch machine, using a weighing method, and the production range is 0.04~32kg/hr.
Weighing-type mixing mixer controller comes with a network interface, and the corresponding software can read the raw material ratio data (such as maximum output, actual output, 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.
4. Dehumidification and drying
Drying becomes a particularly critical stage in the plastic molding process. It is necessary to ensure that the moisture in the raw materials is removed and the drying temperature is reasonable. Shibo's dehumidification dryer 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 the traditional dehumidifier can not be set, the dehumidifier is working in the maximum load state. 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.
5. Extrusion control
For plastic film blowing machines, the air ring is an important component of bubble forming and cooling. The air ring has a great influence on the film thickness uniformity and film output. Shibo chiller is specially designed for extruder air ring cooling, precise temperature control, energy saving and durable.
