We need to master the daily use skills and precautions of packaging scales

Many companies now use some automatic packaging equipment, and packaging scales are one of them. However, we must master the daily use skills of packaging scales to avoid large errors. For example, when the feeding amount of the packaging machine is very unstable, the high speed value should be gradually increased until the small material door has a separate feeding time of about 2-3 seconds; when the small material door alone feeding time often exceeds 3 seconds, The high speed value should be gradually reduced until the small gate has a separate feed time of around 2-3 seconds.

Under normal circumstances, the large material door and the small material door of the packaging scale are opened together at the beginning of feeding, and the large material door is closed when the high speed value is reached; the small material door continues to feed for 2-3 seconds, and the small material door is closed when the fast value is reached; The vibrating feeder continues to feed for 0.5-3 seconds. When the drop is reached, the vibrating feeder is closed and the feeding is completed.

If you need to replace the packaging materials, you should manually open and close the large material door and small material door of the packaging scale several times after the current type of packaging material is finished to remove the residual material; and go to the upper platform to manually clean the vibrating feeder Do not open the vibrating feeder for a long time to clear the residual material remaining in the feeder, so as not to damage the vibrating feeder.

In addition, be careful not to change the parameters such as the set value, high speed value, fast value and drop during the feeding process of the packaging scale. You should change the above parameters when the packaging is not started or the feeding is completed but the scale is not discharging, otherwise it will affect the package. weight; and it is also necessary to manually check whether the action of the large gate, the small gate and the vibrating feeder is normal before use.

If the packaging scale is packing powder materials, the gas breaker must be turned on. The pressure of the gas breaker pipeline should be adjusted to 0.08-0.12MPa; the total pressure gauge should be guaranteed to be 0.4-0.6MPa; The potentiometer on the controller should be adjusted in the 1/2-2/3 position.

When installing the packaging scale, make sure that the longitudinal center of its receiving section coincides with the center line of the material flow in the silo, and that the material flow is naturally accumulated and evenly distributed on both sides of the center line of the receiving section of the equipment, so that the height of the material flow is not equal. Diffuse is the basic principle. If the disc feeding method is used, make sure that the disc discharge drop is not greater than 200mm, and cannot be in contact with any part of the scale.

If it is changed to the drag feeding method, the feeding nozzle cannot contact with the scale body, and the lower end must keep a certain distance from it. In order to facilitate later maintenance and repair, appropriate maintenance space should be reserved when the packaging scale is installed. In short, in order to ensure the accuracy of packaging measurement results, the following requirements must be strictly followed, which is also to prolong the service life of the equipment and improve its work efficiency.
