Reasonable operation procedures for plastic PVC hose machine


Because plastics are recycled resources, the plastics machinery industry is developing rapidly.

Plastic extruder is a common mechanical equipment in PVC hose machine. Grasp the key points of the extruder operation, use the extrusion opportunity correctly and rationally to improve production efficiency and prolong its service life.

The following is a detailed description of the reasonable operation procedures for plastic extruders.

  1. The plastic extruder can start up after constant temperature. The head and flange bolts of the extruder should be tightened once more before starting to eliminate the difference of thermal expansion between the bolts and the head. The order of tightening the head bolts is diagonal tightening, and the force should be uniform.
  2. When the plastic extruder is operated, press the “ready to start” button, then connect the “start” button, then slowly rotate the screw speed adjustment knob, the screw speed slow start. Then gradually speed up, at the same time add a small amount of material. When feeding, pay close attention to the changes in the indication of the host ammeter and various indicator heads.
  3. No one is allowed to stand in front of the die before the plastic profile is extruded during the operation of the plastic extruder in order to prevent injury accidents caused by bolt breakage or wet foaming of raw materials. After the plastic is extruded from the die, it is necessary to cool the extrudate slowly and lead the extrudate up to the traction device and the molding die, and start these devices. Then adjust each part according to the instruction value of the control instrument and the requirement of the extrusion product to make the whole extrusion operation reach the normal state.
  4. when the die is evenly distributed and the plastic is good, it can be used to draw the set. The degree of plasticization should be judged by experience. Generally, it can be judged by the appearance of the extruded material, that is, the surface is lustrous, impurity-free, foaming, coke and discoloration. The extruded material is fined by hand to a certain extent without burrs and cracks, and has a certain degree of elasticity. If the plasticization is bad, the screw speed, barrel and head temperature can be adjusted properly until the requirements are met.
  5. During the operation of the plastic extruder, the process parameters should be checked regularly according to the process requirements, and the process record sheet should be filled in. Check the quality of profile products according to the quality inspection standard, find out the problems and take timely solutions.
