Problem with the plastic pipe production line: There are grooves on the outer surface of the plastic pipe. Solution: Adjust the water outlet pressure of the sizing sleeve to ensure a balanced water output; Adjust the angle of the nozzle in the vacuum shaping box to ensure uniform cooling of the pipes; Check if there are any debris, burrs, etc. on the hardware such as the mouth mold, sizing sleeve, and cutting saw. Problem with plastic pipe production line: vibration ring inside the pipe
Solution: Adjust the water outlet of the sizing sleeve to ensure uniform water outlet; Adjust the vacuum level of the second chamber so that the vacuum level of the rear chamber is slightly higher than that of the front chamber; Check if the vacuum sealing gasket is too tight; Check if there is any vibration phenomenon in the traction machine; Check if the discharge of the host is even
Defects in the plastic pipe production line: The outer surface of the plastic pipe is rough; Solution: Adjust the process temperature; Lower the cooling water temperature, and the appropriate cooling water temperature for the PE pipe is 20-25 ℃; Check the waterway for blockage or lack of water pressure; Check if the barrel and head number heating ring are damaged; Adjust the inlet flow rate of the sizing sleeve; Consult the raw material supplier to check the temperature of the mold core. If it is higher than the temperature of the mouth mold section, lower the core temperature and organize the mold. Defects in the plastic pipe production line: grooves appear on the inner and outer surfaces; Solution: Check if there is water in the inner tube. If there is water, pinch the tube embryo of the newly exported mold tightly to close its inner cavity; Reduce the internal temperature of the mold; Organize and polish the mold. Defects in the plastic pipe production line: no vacuum; Solution: Check if the inlet of the vacuum pump is blocked, and if so, use a needle like object to clear it; Check if the vacuum pump is working properly; Check if there is any air leakage in the vacuum pipeline; Check if the small hole of the core mold pressing screw is blocked, and if so, use fine iron wire to clear it.
Defects in the plastic pipe production line: the outer diameter of the pipe exceeds the standard; Solution: Adjusting the vacuum degree can change the outer circle scale. Adjusting the traction speed can change the outer circle scale. Correct the size of the inner hole of the calibrating sleeve.
Let’s find the reasons from the following three aspects
Check if the temperature is too low, verify if the set temperature of each section is normal, and negotiate with the process technician if necessary to increase the temperature setting value. Check if the heater is functioning properly. If the heater is not functioning properly, it may result in poor material plasticization. Therefore, we need to replace the heater regularly. Check if there are materials that are not easily melted, and clean the kneading system and machine head frequently.
