         What is the failure of the hydraulic cylinder of the plastic bottle baler? How to solve the hydraulic cylinder failure of the vertical hydraulic baler? The oil pump system pressure is low, the plunger rise time is too long, the overflow pressure is adjusted, and the oil return valve leaks. The plastic bottle packing machine is used to squeeze waste paper and similar products under normal conditions, and pack them with special packaging tapes to greatly reduce the volume, so as to reduce transportation volume, save freight, and increase benefits for enterprises. The introduction of advanced technology and advanced technology of similar products at home and abroad.


        Plastic bottle packing machine is a mechatronic product, mainly composed of mechanical system, control system, feeding system and power system. The whole packing process consists of auxiliary time such as pressing, returning, carrying, transferring, outgoing up, outgoing down, and receiving. The structure of the compression frame of the plastic bottle packing machine is basically similar to that of the compression frame, but there are 4 packing heads and 1 set of feeding device on it. The packing head of the plastic bottle packing machine (4 in total) is the part with the more complicated structure and the most chain action of the whole equipment. The packing head of each plastic bottle packing machine has exactly the same structure and can be interchanged.


        Processing method: adjust the overflow valve according to the regulations, the flow rate (unit: cubic meter per second) valve pressure should be cleaned the oil return valve or replaced the spool. The main pump motor current is too large: the main pump motor sound is abnormal, and the overflow valve pressure is not Adjust, the oil is too thick or dirty, the oil level is too low, and air enters the intake pipe. Treatment: adjust the oil supply pressure, replace the clean water, replenish the oil, tighten the intake pipe connecting bolts. The slide valve cannot be reset, it is blocked, reset Spring deformation, pipeline oil is not clean, series bolts are tightened, O-ring seal is aging. Processing method: replace the return spring, clean the pipeline, change the oil, adjust the bolt, balance bolt, replace the O-ring. The gap is in the neutral position of the spool valve Too big; the gap between the replacement body and the sliding is too large, the neutral position is offset, cutting and leaking, the oil compensation overload hydraulic waste paper baler processing method: maintenance repair, replacement of sliding cut, accurate neutral position, replacement, repair or Replace the overload cutting oil.


        The above is the solution to some problems of the hydraulic cylinder of the plastic bottle packing machine. Thank you for reading.
