With the continuous development trend of social development of high-tech, today's multihead weigher has been cultivated. The products that fail to pass the customs can be removed, and the compliance rate of the products can be improved. Zhongshan Smart weigh technology specializes in the production of multihead weighers and various weighing systems for multihead weighers. Today, Zhongshan Smart weigh will take everyone to see the difficult problem of multihead weigher. This kind of problem can be solved by yourself.
The amount of semen multihead weigher multihead weigher shows that the net weight of the information jumps up and down, which is actually a normal situation. The principle of multihead weigher is that the weight sensor transmits the magnetically sensed net weight to the AD converter as a pulse signal when the product passes through the net weight inspection bench. Then it is transmitted to the system software by the AD converter, and the system software transmits the information to the display screen. Since the multihead weigher for semen volume uses high-precision load cells, the load cells are very sensitive to everything outside, including gentle wind blowing, cyclone, etc., so under normal circumstances, the net weight of the multihead weigher screen vibrates. 0.1~0.3g is normal. However, if the net weight of the display screen jumps up and down to 1g or even higher, it is an abnormal situation and must be turned off for inspection.
Rolling bucket multihead weigher Multihead weigher When the net weight vibration range is large, the shutdown inspection must generally check the items: 1. Check whether there is dust on the sensor; 2. Check whether there is an object against the tray; the multihead weigher is a high-speed running high-precision wire. In the inspection of goods, a lot of goods must be transported continuously every day, and the operation must be carried out for several hours without rest, and the operation of high tenacity will inevitably cause some small common faults. So how to solve this small common fault? 1. The zero point of the multihead weigher is higher. Solution: It is necessary to maintain the automatic multihead weigher system software and clear the actual operation of zero adjustment; 2. The multihead weigher has a load without a total value.
Solution: Remove the dust accumulation on the raw material box on the transport electronic belt scale body, and maintain the surface cleaning of the automatic multihead weigher transmission belt; 3. The instantaneous total flow of the multihead weigher fluctuates greatly. Solution: Align the drive belt of the belt conveyor with both ends of the axis of the tray; 4. The deviation of the multihead weigher measurement verification is large. Solution: Check whether the solid-state structure of the production line weighing system is solidly installed, correct the position of the conveyor belt, accurately measure whether the distance between the weighing cable bridges is suitable, and whether the instantaneous total flow is normal; 5. Multihead weigher output standard Values fluctuate frequently.
Solution: The transmission belt must be aligned with the axis of the tray, and then re-calibrated; the above content is for your reference on how to solve the problem that the automatic multihead weigher cannot weigh. 6. The repeatability of multihead weigher calibration is not very good. Countermeasures: If the speed data signal of the multihead weigher is abnormal, it indicates that the weighing data signal is unstable, and it is necessary to check whether the contact of the terminals of the weight sensor is good.
