Many users tend to ignore the routine cleaning and maintenance of packaging scales. In fact, these two aspects of work are very important. Doing a good job can greatly increase the service life of the packaging machine and reduce the failure rate. Negligence can have a negative impact.


As a special packaging and weighing equipment, the packaging scale must be operated by fixed personnel, and the staff are required to be proficient in the boot-up and bag-making procedures, as well as simple instrument debugging and parameter changes. The basic requirement for the daily maintenance of the packaging scale is to ensure that the inside and outside of the computer instrument box is clean and dry; in addition, it is also necessary to regularly check that the terminals are not loose or fall off to ensure that the circuit and gas path are unblocked.


After the packaging scale is shut down, the measuring part should be cleaned in time. If the packaging is sugar, Banlangen granules, salt, etc., it is necessary to ensure that the feeding tray and turntable are cleaned every shift so that they are not corroded. The heat sealer body of the packaging scale should be cleaned frequently to ensure a clear texture of the seal.


The main points to be cleaned are the photoelectric tracking light-emitting head of the packaging scale, the scattered materials on the material tray, the dust in the electric control box, etc., to ensure the small error of the cursor tracking, keep the parts clean, and prevent the electric control box from being in poor contact. wait for failure. The transmission and moving parts of the packaging machine must be inspected, tightened, refueled and maintained within a week of use; after that, it must be regularly inspected and maintained every month.


Regularly check the screws of all parts of the packaging scale to avoid loosening; at the same time, pay attention to the waterproof, moisture-proof, anti-corrosion, and rat-proof of the electrical parts; the electric control box and the terminals should be kept clean to prevent the electrical failure of the packaging scale. If it needs to be stopped, the two heat-sealing rollers of the packaging scale should be in the open position to prevent the packaging materials from being scalded; as well as the meshing parts of the gears of the equipment, the oil filling holes of the seated bearings and the moving parts, oil should be regularly lubricated.


If the solenoid valve of the packaging scale fails, it will cause the PLC signal output of the equipment, and the solenoid valve body will be stuck, causing the actuator to not act. This also reminds the majority of users that they must regularly check the action of the solenoid valve in the packaging scale, and disassemble and clean the valve body in time and add grease.


There is also a problem that when the start button of the packaging scale is pressed, the large and small material doors cannot be opened, and material feeding cannot be performed. Analysis proves that the reason for this phenomenon is that the packaging scale has not been used for a long time, and there is still a certain amount of finished products in the hopper, which causes this phenomenon to occur.


When encountering a similar situation, the first is to clear the hopper of the packaging scale, and then clear the value of the instrument to zero. In order to avoid the recurrence of this phenomenon, if the packaging scale is not used for a long time, the hopper must be cleared in time to keep the empty warehouse.


The same is about the problem of the packaging and weighing door. Although the door cannot be opened, the display of the instrument is normal at this time. After careful inspection, it is found that there is a problem with the power supply of the solenoid valve that controls the material door, specifically because the finished product of the packaging scale Corrosion of the wiring terminals caused by the dust in the solenoid valve leads to poor contact of the power supply circuit of the solenoid valve. This kind of problem can be solved by re-processing the wiring.
