The normal operation of chain zipper machine is the main transportation equipment for coke oven coal supply in coal preparation section. The chain zipper machine should be checked in detail before starting the nearby barrier-free, whether there are tools and debris in the chain zipper machine, the signal can be opened j machine after normal conditions. After the chain zipper is started, attention should be paid to check whether the chain runs off track and slips, whether the upper and lower idlers are missing, whether the rotation is flexible, and the temperature rise of bearings and transmission devices in various places. If problems are found, they should be dealt with in time.

For the chain slip of chain zipper machine, according to the reason of its existence, we should adjust the tail tensioning device or the head drive drum lining or improve the head of the wheel position to increase the packaging Angle and other methods to solve.

For chain zipper machine chain deviation: Generally by self-aligning roller automatic adjustment, the chain run partial serious tail can be adjusted according to the reasons of the existence of its use of tensioning device, the head and tail roller or timely _ the adhesion of coal material, or improve the chain of uniform feeding, even need correct chain installation, make the chain zipper machine allowed to meet the requirements of the relevant technical documents and so on ways to solve.
