Failure analysis of zipper mechanical chain disconnection

The zipper machinery is the main equipment for the production of zipper products. Based on the rich experience in the past, the machinery has summarized and analyzed the reasons for the disjoint failure of the zipper machinery chain: 1. When the chain of the zipper machinery and equipment is not tight enough, If it is too loose, the chain sag between the sprocket and idler, idler and idler of the zipper machine is too large, and the chain swings up and down when moving. Jump out of the shaft slot. 2. The chain of the zipper machine has a certain sag during the transmission process. When its chain links are separated from the sprocket, they move at an uneven speed, accompanied by changes in direction and size. When the speed of the chain link is higher than that of the chain link in front of the chain link when it is separated from the sprocket, because the opening of the hanging shaft slot is relatively close, the hanging shaft will jump out of the hanging shaft groove. 3. Due to the local shedding of the concrete in the chain groove, sometimes it interferes with the chain link, which makes the running resistance change greatly, aggravates the shaking of the chain, and causes disjointness. When the resistance is too large, after the equipment jumps to a stop, the driving wheel is reversed in a small amount. At this time, the chain link behind is long and the sag is large and cannot be carried, which is also easy to cause disconnection. 4. When the follow-up equipment of the zipper machine is stopped, the zipper machine is not stopped in time, causing the discharge port to be blocked, and the material between the sprocket and the chain link will change the meshing, and the chain will be loose and tight, making the chain disjoint possible. .
