What is a feeding system?
In China, the injection molding machine is in a dominant position in the field of plastic processing machinery. Injection molding machine is a kind of mechanical equipment that can make thermoplastic or thermosetting plastic into various shapes of plastic products through plastic molding molds. It is the plastic machinery equipment with the largest output, the highest output value and the most exports in China. With the development of injection molding machines towards high speed, high efficiency, mechanization and automation, the feeding method has gradually changed from manual to automatic. Here are several common forms.
①The spring automatic feeding device is a spring automatic feeding device used for plastic injection production. The automatic spring feeding device is usually composed of a motor, a spring chuck, a feed port, a spring and a plastic hard tube. When working, the motor drives the spring to rotate at high speed to generate axial force and centrifugal force. Under these forces, the material rises along the plastic hard tube. When it reaches the inlet, due to the centrifugal force, it is thrown to the outlet and enters the hopper. Its conveying capacity depends on the spring speed, the outer diameter of the spring, the pitch, and the gap between the outer diameter of the spring and the inner wall of the plastic hard tube. The diameter of the spring wire should not be less than 6mm, otherwise it will be easily broken. The device is mainly used for conveying powdery materials, commonly known as powder feeding machine, which is used for feeding single equipment in the workshop.
②Blasting feeding device includes upper storage silo and lower storage silo, and also includes conveying pipeline and blower. It is a device that uses the negative pressure of the fan to suck up the granular plastic. The blast feeding device mainly uses wind force to blow materials into the conveying pipeline, and then enters the hopper through the cyclone separator. The delivery capacity of this central feeding system is related to the length of the pipeline. The device is mainly used for conveying granular materials, usually using the central feeding system of large factories.
③ Vacuum feeding device is a kind of equipment that produces vacuum conveying plastic through vacuum pump, which is a kind of pneumatic conveying. . When the vacuum feeding device is working, the vacuum pump forms a vacuum in the small hopper, and the material first enters the small hopper through the feed pipe.
When the material in the hopper is stored to a certain amount, the vacuum pump stops working. The feed is stopped due to the disappearance of the vacuum in the small hopper.At this time, the sealing cone opens and the material falls into the large hopper.When the material is finished, the sealing cone is lifted up due to the weight of the hammer, and the small hopper is closed again Touching the micro switch causes the vacuum pump to start working again, and the milk circulates back and forth. The device is mainly used for conveying granular materials, usually used for feeding single equipment in the workshop.
The feeding system enables the dehumidification and drying of raw materials, which can save electricity consumption and baking time. The long-distance feeding system adopts advanced technology and has a long service life, so it can be purchased with peace of mind.
