Bottle blowing machine product detection abnormalities and solutions, blowing machine-professional machinery equipment manufacturer
Blow molding machine product detection abnormalities and solutions: preform injection section semi-finished preform injection weight, bottle mouth size, stress line conditions beyond the process control range, double sampling and measurement, if the excess is true, issue an isolation order and notify the production improvement, And follow-up. Semi-finished products below the lower limit of the specification are isolated. 1. The bottle mouth size of the semi-finished product in the crystallization section of the bottle mouth, and if the crystallization condition of the bottle mouth is checked, double the sampling and measurement. If the excess is true, an isolation sheet will be issued to notify the production improvement, and Follow-up. Semi-finished products are isolated for inspection during the relevant period. 2. Blowing section finished products (1) Bottle height, bottle wall thickness, carcass diameter size, injection point capacity, capacity shrinkage rate, carcass diameter shrinkage rate, exceeding the process control specifications When the range is exceeded, the sampling measurement is doubled. If the limit is exceeded, an isolation form will be issued to notify the production improvement and follow-up. (2) Heat resistance: After hot water is filled, the center temperature of the bottle is 91±1℃, and the bottle body is obviously deformed. , And then double the sampling and measurement. If the excess is true, issue an isolation list, notify the production improvement, and follow-up. (3) When the load, drop strength, and heat-resistant vacuum index do not meet the specifications, double the sampling and measurement. If the excess is true , Issue a quarantine order, notify the production improvement, and follow-up. (4) When the appearance of the product is slightly abnormal, contact the production line to take preventive measures to avoid the occurrence of unqualified products. When the appearance is serious, issue a quarantine order to notify the production improvement, and the relevant period Semi-finished products are isolated for inspection. 3. Tracking and isolation of non-conforming products Once non-conforming products are found in production, they should be notified immediately for on-site adjustment and improvement, and at the same time, the defective products are tracked and isolated. The operation method is as follows: random inspection of the previous stack produced during this period If a defective product is found on the board, continue sampling the adjacent and previous pallet until no defective product is found.
