Return the cots to the non-working position. Remove pressure from work rolls. To slow down a machine. When the temperature of each work roll is lower than 80 degrees, it can be stopped.
3.7 During the operation, the operator must judge whether the equipment has great vibration, whether the parts are loose, and whether there is abnormal sound and odor during operation at any time by senses, so as to judge whether the equipment runs normally. If any abnormal situation is found, immediately stop the machine and report to the monitor and promptly notify the mechanic and electrical repairman for inspection and maintenance.
3.8 First Test: When confirmed by the production line preliminary qualified products (generally no more than 20 meters), monitor organization long corrugated machine, double sided gluing machine machine head, cardboard line engineer in the preliminary confirmation of qualified products randomly 3, the appearance, size, surface, color paper, adhesive, water cut, etc. To confirm, after waiting for the above content inspection requirements, notice to normal production; If the product does not meet the requirements, the monitor shall give instructions to stop the machine to find out the reasons for the nonconformity and solve the problem. When the causes of the nonconformity are eliminated, the first inspection shall be conducted again and the normal production shall be carried out. (The indicators of the items to be inspected are carried out in accordance with the “Corrugated Board Enterprise Standard”).
3.9 All finished cardboard products (including waste and defective products) must be stacked on wooden pallets, and the stacking height should be 2 meters (including the height of pallets), and the stacking must be neat and beautiful, without deflection or even collapse.
3.10 On Duty Where a lot is found to require remediation during production, the remediation must be completed at the end of the lot to ensure that it can be transferred to the next process.
