In the plastic processing industry, whether it is extrusion, injection molding, calendering, hollow molding, film blowing, spinning, etc. , in addition to meet the requirements of the host, often need a lot of auxiliary equipment to complete all kinds of processing procedures. These mechanical equipment that play an auxiliary role in plastic processing are plastic mechanical auxiliary equipment, referred to as plastic auxiliary equipment.
Second, what are the auxiliary equipment of plastic machinery?
Plastic processing needs a lot of auxiliary equipment. Generally speaking, the auxiliary equipment of plastic machinery can be divided into three categories according to their functions: feeding system equipment, temperature control system equipment and scrap recycling and crushing equipment, specifically:
Automatic metering and feeding device, automatic scrap recycling device, automatic injection product taking-out device, rapid injection mold replacement device, injection mold cooler, automatic thickness measuring device, raw material conveying and storage equipment, etc.
Third, what is the use of plastic mechanical auxiliary equipment?
Although the auxiliary equipment of plastic machinery is auxiliary equipment, they are also an indispensable part of modern plastic processing automation, and they play different roles in plastic processing:
1. The equipment of the feeding system provides high-quality raw materials.
The auxiliary processing equipment of the feeding system mainly includes drying, conveying, metering and mixing equipment: the drying equipment is used for material pretreatment before molding and the production of easily hygroscopic materials; The conveying equipment is used for conveying plastic processing raw materials; The metering equipment is controlled by computer, and all kinds of raw materials are weighed in proportion by the metering device and then enter the mixer; Mixing equipment is used to evenly mix materials.
2, temperature control system device to ensure product quality.
In the process of plastic processing, heating equipment mainly refers to the temperature heating controller of cylinder die and calendering roller used in production equipment such as extrusion, injection molding and calendering. At present, the complicated steam heating method is generally replaced by the electric heating method of heat transfer oil.
Mold temperature cooler is mainly used for mold temperature cooling of injection molding. Generally, mold design has cooling water channels. Refrigerators can be divided into air-cooled and water-cooled. Although air cooling is portable, it is widely used because of its low heat exchange capacity, large heat exchange capacity and good heat exchange effect.
3. The crushing equipment is used to recycle the corner waste, which reduces the production cost.
In plastic processing, the proportion of waste materials accounts for about 5% ~ 20% of the total output. In order to reduce the production cost and avoid waste, special recycling auxiliary equipment is needed and more plastic shredders are used. Now it is developing towards the direction of low noise, easy operation and continuous pipe conveying and unloading in the hopper.
