Our factory has a newly purchased PYQ1300 flat press creasing cutter in the initial use. When it is used once, the drive shaft cannot be operated after pressing the “Pressure Cut†button, so that the linkage can not be driven to reciprocate the press frame. Press the paper product. When the operator inadvertently touches the bearing housing on the right side without cutting off the power supply, the drive shaft suddenly operates to move the link rod to actuate the press frame. One can imagine that such hidden troubles are very dangerous.
What is the reason for such sudden and unresponsiveness, but the strange phenomenon that it has acted upon the bearing and will act on its own? We immediately shut down for fault checking. Initially, we thought that it was caused by poor contact between the carbon brush and the ring. Therefore, normal handling of the carbon brush and the contact along the ring was performed, but there was no effect. Can it be the electromagnetic clutch coil failure? By detecting the absence of open circuit or short circuit in the coil, the problem of poor wire contact is detected. At the same time, in the case of energizing the coil in the field inspection, a piece of steel (an Allen wrench or a screwdriver) is used to contact the steel ring of the coil. The surface (and the surrounding surface) produces a noticeable sticky feel to the steel, which is the magnetic attraction that occurs when the coil is energized. By inspection of the above method, it can basically be determined that the clutch coil is normal.
Charcoal brush and poor contact along the surface of the ring; clutch coil failure problem may occur "pressing" button can not be operated after the press, which in our past use of this type of equipment repair has occurred and Processing example. So, why do similar failures not belong to these two reasons?
Through in-depth analysis again, we believe that the above-mentioned failure caused by the large clearance between the friction ring and the friction wheel. So the gap was made to regulate the adjustment (usually the gap is adjusted to 2-5mm is appropriate), the fault can be completely ruled out.
Why does the above-mentioned failure situation occur when the gap distance between the friction ring and the friction wheel is not too large? I believe that because the gap distance is too large and in the case of too large and not much, it will normally operate normally, but sometimes it will appear after the clutch coil is energized. Although a pull-in action occurs, the pull-in is not fully achieved. In the normal position (or not tight), the transmission shaft in this state cannot move the connecting rod. However, when the friction ring is touched (touched inwards), the gap between the friction ring and the friction wheel is reduced. To make the oversize fit, and then instantly pull it in place, a normal start appears. The above-mentioned reason why the operator could not start after pressing the “Pressure Cut†button, and in the case of not cutting off the power supply, when the right bearing block is touched, the phenomenon that the drive shaft is suddenly operating again is also the reason. Because the bearing seat is assembled with an adjustable friction ring, actuating the bearing seat also touches the friction ring. This caused the above situation to occur.
It can be seen that, like this type of equipment, whether or not the adjustment of the distance between the friction wheels is appropriate is critical. In operation and use, the friction plates will be worn out, and if used to a certain extent, the original adjusted and adjusted clearance distance will change ( If the distance becomes larger, if it is not adjusted in time, it will definitely affect the work performance and the safety of the equipment. It is worthy of attention.
PYQ1300 indentation cutting machine is a special equipment for cutting all kinds of cardboard, leather, plastic products, etc. The effective area of ​​the machine is 1300 X 920 (mm), which can press the paper product with extra size. The machine is mainly composed of base, press frame, high-power two-way electromagnetic clutch transmission mechanism, electrical control, etc. The motor mounted on the right side of the base is driven by the flywheel to drive the drive shaft, and the drive lever is driven by the secondary gear to drive the pressure of the connecting rod. The reciprocating motion is performed to complete the task of pressing the paper product. The disk-type bidirectional electromagnetic clutch transmission mechanism is mounted on the drive shaft, and the operation and braking of the drive shaft are controlled by the action of the electromagnetic clutch being disengaged and disengaged.
