The common adjustment method of film laminating machine bias grinding phenomenon
1, laminated film machine in the use of the process is also easier to present various types of questions, we encounter the questions should be given in a timely manner after the investigation, to avoid the formation of composite machine machine damage, the following joint giant small part for us to introduce the composite machine to send bias grinding when how to give adjustment.
2, if the laminated machine partial grinding scene, the need to check the piston and cylinder sleeve cooperation accuracy, and in the production process to adopt methods to avoid partial grinding. Film compound machine replacement seal, pay attention to safety and avoid bringing in the spoils, support (under the beam) four corners of the "top bar" to support the stability of the operation. Compounding machine first up under the bushing pressure ring (large diameter piston pressure ring is too heavy, compounding machine can use small manual hoist lifting), with wire hooks one by one to remove the seal, replaced with a new one, and then tighten the pressure ring.
3, dripping film composite machine found some air leakage, you can use welding patch, welding should be experimental water pressure, the pressure of steam pressure 1.2-1.4 times, and repair the flat welding patch. If the leakage is caused by serious internal corrosion, should be replaced. To avoid the occurrence of the seal ring "flip" scene. Compound machine to replace the seal ring to carefully check, analyze the damage factors, in order to adopt preventive measures. Rubber sealing ring specifications, structure and shape, solvent-free composite machine in accordance with the rules of the drawing specification selection, can not be changed at will.
4, laminated machine steam elbow tube seal ring of many hot presses, steam pipe rolling joints, are using asbestos packing sealing equipment. Compounding machine at high temperatures, asbestos filler is easy to harden to present the scene of air leakage. Choose the better sealing function of the ball joint and PTFE seal ring is better, the seal ring can generally be used for about 1 year. Composite machine will also have asbestos line dipped in PTFE plastic, in the original stuffing box compression use, the role is also striking, but the use is not very convenient. When replacing the seal, the ring behind the sphere needs to be blocked at an angle of 45 ° oblique before it can be set, but does not affect the sealing effect.
5, dripping film laminating machine broken or large and small slabs, can not enter the laminating machine. Do not allow the liner plate directly limit the fiberboard. Compounding machine shutdown for a longer period of time need to promptly sweep away the steam condensate inside the compounding machine to avoid internal rust. Some (or all) of the composite machine is not hot, clarifying the internal channels have blocking scenes. Or the channel has a "short circuit" scene.
6, generally because of the laminated machine channel within the original fixed "plug" off or move the position of the formation, but sometimes also due to serious rust caused by corrosion. Composite machine if a lot of exhaust, still can not be some of the heating back to normal, composite machine needs a special deep hole drilling machine to open the channel to view, remove the obstacles, only after the continued use.
