1. Uneven motion of the chain: The chain has a certain degree of sag in transmission, and when the chain link disengages from the sprocket, it moves at an uneven speed, accompanied by changes in direction and size. When the chain link detaches from the sprocket and the speed is greater than the front chain link, the hanging shaft will jump out of the hanging shaft slot due to the close opening of the hanging shaft slot.

2. Chain too loose: When the chain is too loose, the chain sag between the sprocket and the supporting roller, as well as between the supporting roller and the supporting roller, is too large. When the chain moves, it swings up and down. Due to the close proximity of the hanging shaft to the opening, the hanging shaft will jump out of its hanging shaft groove.

3. Interference between the chain groove and the chain causes oscillation: Due to local detachment of the concrete in the chain groove, sometimes it interferes with the chain link, causing significant changes in running resistance, exacerbating the shaking of the chain and causing detachment. When the resistance is too high, it can cause the equipment to jump and stop, causing a small amount of reverse rotation of the driving wheel. At this time, the rear chain link cannot move due to the long and large sag of the chain, which can also easily cause detachment.

4. Improper operation: When the subsequent equipment of the zipper machine is stopped, the zipper machine is not stopped in a timely manner, resulting in a blockage of the discharge port. The material is sandwiched between the sprocket and the chain link, causing a change in meshing. The chain is loose and tight, making it possible for the chain to become detached.
