Hydraulic Metal Baler Operation Sequence
⑴ No-load operation: the four manual directional valve handles are in the neutral position respectively, and the motor is started. At this time, the high-pressure oil returns to the oil tank through the valve, the system is unloaded, and the oil cylinder does not work.
⑵Under the door cover: push the door handle of the door cover cylinder forward, the door cover cylinder pushes the door cover closed, the primary compression of the material, the lock head is inserted into the lock cover to lock the door cover so that it does not float. After the pressure value reaches the system pressure, pull the handle to the neutral position and the system is unloaded.
⑶ The side pressure cylinder enters: After the door is closed, pull the side pressure cylinder valve handle to the front position, the high pressure oil enters the side pressure cylinder rear chamber through the side pressure cylinder valve to push the piston forward, and the side pressure head advances to perform secondary compression on the material. After the stroke of the cylinder is in place (the pressure value reaches the system pressure), move the handle to the neutral position.
⑷ The main pressure cylinder advances: After the side pressure cylinder advances into place, pull the valve handle of the main pressure cylinder to the front position. The main pressure cylinder pushes the main pressure head forward, and finally compresses the material. The boring is finally compressed and shaped. After the pressure value reaches the system pressure, after holding the pressure for 3-5 seconds, pull the handle to the neutral position.
⑸ Return stroke: Move the main pressure cylinder and side pressure cylinder valve handles to the rear position in turn, and return the main and side pressure cylinders. After the return stroke is in place, pull the door cover cylinder valve handle to the rear position. The piston rod drives the slider to pull out the lock and open Door cover.
⑹ Top bag: Turn the valve handle of the bag turning cylinder to the front position, and the bag turning mechanism will work. Turn over the compressed block in the compression chamber out of the bin, and remove the block.
⑺ Top bag reset: Turn the valve handle of the bag turning cylinder to the back position, and reset the bag, turn the valve handle of the bag turning cylinder to the neutral position, and then move the valve handle of the door cover cylinder to the middle position, and the bag turning cylinder stops working.
Note: 1. For each action to be in place, the handle needs to be restored to the neutral position. 2. When the top bag and the top bag are reset, the main pressure cylinder and the side pressure cylinder must return, and the door cover must be opened in place. Do not turn over the bag when the door is closed to avoid damage to the machine. 3. Pay attention to the amount of feed when feeding, to avoid the disadvantage that the package is too long and the package cannot be turned out of the box.
