Rubber film/sheet batch-off machine process:
1. The rubber from the extruder in the internal mixing workshop first enters the front discharge device of the film cooler. The front part of the take-off conveyor is composed of a high temperature resistant conveyor belt, and the back part is composed of a power roll system. The conveyor belt is heat – and corrosion-resistant nitrile tape without joint. The device has a deviation correcting device and an automatic tensioning device.
2. After the rubber is removed from the front, it enters the isolation coolant water tank through the pinch roller. Divided into main and secondary water tanks, single-layer structure. The film goes into a soaking tank, where it is soaked in a spacer and initially cooled. The immersion tank is provided with a cooling circulation device and a spacer mixing pump. Then, the lifting and hanging device is put in, and the line speed match with the upstream frame is guaranteed by the G120 inverter.
3. After that, the film soaked with the spacer is clamped and lifted by the conveyor belt, and enters the air cooling device through the plastic module conveyor belt. The lifting device has automatic film hanging function. Lifting position Add glue conveying machine, can adjust the lifting Angle (to adapt to soft and hard rubber material), so that the entrance of the hanging film smooth, do not squeeze glue. The film conveyed by the lifting device can automatically enter the glue hanging rod to prevent glue blocking, thus ensuring reliable automatic glue hanging, avoiding the danger of manual glue hanging, and reducing the difficulty of operation. At the same time, it is equipped with a detection device, which automatically alarms and stops working when the glue is blocked. PLC control, so that the length of the hanging glue is consistent and neat, with manual and automatic functions.
4. When the photoelectric switch of the automatic picking waiting position detects the cooled rubber, the lifting cylinder of the automatic picking device will drop from the lifting limit position to the waiting position, waiting to grab the rubber. When the film grabbing photoelectric switch detects the position of automatic gluing and film grabbing. The lifting cylinder of the automatic gluing device moves from the holding position to the grasping position. At this point, the grab drum contracts to grab the film. After grasping the cylinder to shrink to the upper limit magnetic switch, lift the cylinder to the rise limit position. After the magnetic switch is energized, the translation cylinder moves to the limit position of the translation cylinder. When the magnetic switch is energized, the piston rod of the cylinder extends to press the film. After the magnetic switch is energized, the conveyor motor and the film swing motor start. When the conveyor belt is running, the film enters the conveyor belt press roll and approaches the switching power supply. The piston rod of the press roll cylinder retracts, and the translation cylinder retracts. The swing width of rubber is processed by PLC on the basis of setting, and the width of each layer is reduced.
