The weighing machine is inaccurate? how to find out why
In recent years, with the rapid development of China's economy, the demand for product packaging has also improved. In the early stage, the manual detection method adopted by the production enterprises not only has low efficiency, low probability of occurrence, but also requires a large amount of labor, which leads to increased costs, and is prone to underweight or missing parts, which greatly affects the customer's impression of the product image. Weighing machines are familiar to many enterprises, and a weighing machine is a high-precision device that automatically detects the weight of packaged products. It is often used in automated production processes to perform in-line weighing tests to ensure that the weight of the packaged product is within the specified range. Any packaged product exceeding the specified value will be automatically rejected. It can not only improve production efficiency and ensure product quality, but also save time cost, capital and management cost, reduce downtime, eliminate product loss, and create great value for users. Automatic can be used at the front end of scanners, case sealers, coding equipment or at the end of a packaging machine line. It is a high-speed and high-precision automatic weight detection equipment. The application of the weighing machine can double the production capacity of the production line of the enterprise and solve the problem of labor costs. In the process of use, how to find out the reason for the inaccurate weighing of the weighing machine? 1. Check whether there is wind blowing on the equipment. 2. Whether the device is calibrated or not, it can be recalibrated. 3. Check whether there are other items touching the weighing tray. 4. Compare static weighing with dynamic weighing, if not, it can be corrected by 'dynamic learning'. Cleaning of the weighing machine Cut off the power supply of the weighing machine and unplug the power cord. Wet the gauze, wring it dry, put it in a small amount of neutral cleaning solution, use it to clean the weighing pan, and display the main parts of the weighing such as the filter screen. Calibration of the weighing machine Check whether the scale body is normal. If it is angled, adjust the proportional foot so that the blister is centered. Clean the printer of the weighing machine and cut off the power supply, open the plastic door on the right side of the balance, hold the plum handle on the outside of the printer, and drag the printer out of the balance. Release the print head according to the spring of the front end of the printer, gently wipe the print head with the special print head cleaning pen attached to the weighing fitting, remove the dirt on it, remove the cap, cover the cleaning pen to prevent the volatilized liquid, then wait for two minutes until completely The cleaning liquid of the print head evaporates, then close the print head and the printer. Push it into the scale body, close the plastic door, test it with electricity, print it clearly, and it can be used normally. Initialization of the Weighing Machine The weighing machine has the functions of zero tracking and power-on clearing. It can clear the foreign objects on the weighing pan when it is turned on, and ensure that the scale is turned on and used when there is no wind around. If there is a little weight displayed after turning on the machine, you can press ' 'Zero' key to restore the scale to zero position. During the weighing process, the weighing machine should ensure that no foreign objects touch the sensor around the scale, and the bottom of the sensor should also be clean and free of foreign objects, otherwise it may cause problems such as inaccurate weighing.
