The whole process of online automatic checkweigher installation and the handling of common problems
1. Disassemble the wooden packing box, loosen the fixed screws and other equipment of the checkweigher. 2. Install the weighing tray (handle carefully, and be careful to damage the checkweigher): 1) First unscrew the screws on both sides of the fixed guide bar, remove the guide bar; 2) unscrew the weighing Tighten the 4 thumbscrews on both sides of the tray, and take out the drive belt tray (pay attention to the timing belt when removing it.) 3) Remove the weighing tray in order to better maintain the sensor. Take out the 4 screws on the seamless steel tube and take out the weighing tray. 4) Remove the screws (four or two) from the checkweigher, the screw spring washer and a large stainless steel plate washer. 5) Align the large stainless steel plate washer with the hole on the top of the checkweigher machine, then put the weighing tray on the stainless steel plate washer, align the hole, and fix the weighing with the screw removed from the top of the checkweigher. Drag tray. 6) Install the drive belt tray on the weighing tray, and tighten the thumb screws. 7) Prepare the guiding strip and tighten the screw. 3. Switching power supply connection: 1) Connect the switching power supply of AC380V±10%50HZ. 2) In order to prevent electric shock accidents and ensure the smooth operation of the machine and equipment, please try to connect the power cord plug to the grounding device (the wire connector should be made of soft copper core wire with a diameter of 1.6 mm, or should have the same compressive strength and not easily corroded The characteristic impedance of the metal wire and the grounding device must be less than 100 ohms. 3) In order to better prevent risks, please install an isolating switch on the switching power supply presented to the machine. If it is used in a wet and cold natural environment, a leakage protector must be installed; 4. Connect a pneumatic valve with a working pressure ≥ 5kg/cm2, and pay attention to the position of the pneumatic valve on the pressure reducing valve. Up to now, you have basically understood the basic concepts of checkweighers. This chapter mainly discusses the following question types: machinery and equipment cleaning on the calibration line. Remember to turn off the switching power supply before cleaning the equipment. The detachable conveyor belt can be sterilized or cleaned with warm water at about 60℃. It can be used to soak the conveyor belt in boiling water for five minutes. Or use hypochlorous acid water solution (200ppm) to soak (within 3 minutes), and then clean with tap water. No matter which method is mentioned, please make sure that the cleaned conveyor belt is fully dried before installing it on the conveyor belt . In avoiding moldy conditions. Installation and adjustment 1. Installation of the conveyor belt: 1) Turn the adjustment nut to adjust the distance between the driven shaft and the gear shaft to the minimum; 2) Check the operating position of the transmission belt, and insert the transmission belt in the direction of the thick arrow symbol (Figure 1) Drag tray. 3) Adjust the adjusting nuts on both sides of the tray to make the tension of the transmission belt appropriate. And place the transmission belt on the management center of the tray. 2. Adjustment of the conveyor belt 1) Adjust the tension of the transmission belt to an appropriate degree, put it on the machine, and observe the operation of the leather; 2) If the transmission belt is in the middle of the tray, it is in all normal conditions and no adjustment is required; 3 ) If the transmission belt deviates to the left, the following adjustments can be carried out: The left transmission belt can be adjusted tightly, which requires gradual adjustment. It is standard to observe while adjusting until the transmission belt returns to the management center. If you find that the adjustment nut is too tight, do not force adjustment. The transmission belt on the right side can be adjusted loosely, which needs to be adjusted gradually. It is standard to observe while adjusting until the transmission belt returns to the management center. If the deviation is larger, and you can't go home after adjusting gradually, you can quickly loosen the transmission belt on the right side. If there is friction between the transmission belt and the side partitions, it should be shut down immediately for inspection.
