What are the basic requirements for daily maintenance of packaging scales?

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 startup and bag making procedures, simple instrument debugging, changing parameters, etc. 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.

It is also necessary to focus on cleaning the photoelectric tracking light-emitting head of the packaging scale, the scattered materials on the 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.

With the advancement of technology, electronic weighing technology has become an important technology in modern weighing measurement and control system engineering, and electronic quantitative packaging scales are the specific application of this technology in quantitative systems. Different from ordinary packaging scales, electronic quantitative packaging scales can achieve dynamic quantitative weighing with high weighing accuracy and high weighing speed, which is of great significance.

The reason why the electronic quantitative packaging scale can do this is inseparable from its technological process and functional characteristics. The operation process of the electronic quantitative packaging scale is divided into two parts: automatic and manual. The automatic part refers to its feeding, weighing Heavy, while the manual part is responsible for bag clamping, unloading and feeding.

The feeding device of the electronic quantitative packaging scale is a large and small two-stage feeding method. When the material weight reaches the set value of the medium feeding, the fast feeding will be stopped, and the small and accurate feeding will be maintained; when the material weight reaches the set drop value , close the feeding door to complete the dynamic weighing process.

At the same time, the system of the electronic quantitative packaging scale will detect whether the bag clamping device is in a predetermined state. When the packaging bag is clamped, the system will send a control signal to open the discharge door of the weighing hopper, and the material will enter the packaging bag. The unloading door of the weighing hopper is automatically closed; after unloading the material, the bag clamping device is released, and the packaging bag automatically falls; this cycle runs automatically.

In the electronic quantitative packaging scale, 24-bit high resolution is adopted, which is suitable for 4 or 6-wire various characteristic value weighing modules. Not only the sampling frequency can be selected in a wide range, but also the filtering function is powerful, so the numerical value caused by vibration is reduced. Fluctuations, the processed data is transmitted to the programmable controller with high precision and high speed.

The electronic quantitative packaging scale can rely on the powerful control function of PLC to make the equipment reflect excellent performance, greatly improve the weighing speed, and greatly improve the stability of the equipment. When the touch screen is in good communication with the PLC, the electronic quantitative packaging scale can complete the real-time display of the weighing, the data display is sensitive, and the weighing process data rolls obviously.
