Analysis of injection molding of centralized conveying system
There are many types of plastic molding methods in the central conveying system, and each method has its own different characteristics!
There are mainly the following methods for plastic molding in the centralized conveying and feeding system:
1. Injection molding: Plastics are first heated and melted in the heating barrel of the injection molding machine, and then the reciprocating screw pushes the melt into the cavity of the closed mold for molding.
2. Extrusion molding: a method in which the plastic is continuously passed through the die in a flowing state by heating and pressing in an extruder.
3. Foam molding: refers to the processing method of adding proper foaming agent to foam material to produce porous or foamed products.
4. Blow molding: refers to a molding method in which the hot thermoplastic parison or sheet in a closed mold is blown into a hollow product by means of fluid pressure.
Pay attention to the following points when using the central feeding system:
1. Before starting, the driving wheel should be moved one or two laps by manpower. After confirming that the movement is flexible, the central feeding system should be opened for operation, and the feeding should be performed after the central feeding system is operating normally.

2. Pay attention to the temperature of the bearing during operation, keep the bearing in a good lubrication state, and pay attention to the sound and
Whether the vibration is abnormal. When an abnormal situation is found, the first step should be to stop the machine and check whether it is stuck by something that is not easily broken, or
The central feeding system is damaged.
3. Check whether the particle size of the crushed product meets the requirements. If there are too many particles exceeding the specified size, the reason should be found (such as
The screen bar gap is too large, the discharge port is too wide, the hammer is worn out, etc.), and appropriate measures should be taken to deal with the problem.
4. It is necessary to maintain uniform feeding of plastic central feeding system products to prevent overload. Strictly prevent metal and wood from breaking
The object falls into the machine. When it cannot be crushed, the feed water content cannot be too high; when wet crushing, proper water is needed to prevent
Clogging due to insufficient flushing water reduces production capacity.
5. Worn out parts should be replaced or repaired in time.
6. The safety device of the central feeding system must be kept in good condition. It must not be an effort to make the safety device invalid. 7. When the central feeding system is shut down, check whether the fastening bolts are firm and the degree of wear of the easily worn parts . Such as
If you pay more attention to it in daily use, you can make the central feeding system more durable and more profitable for the enterprise.
8. Before stopping the operation of the central centralized feeding system, you should stop feeding and drain the materials in the machine first, and then cut off the power of the motor!
