Quantitative packaging scale consists of four parts: automatic weighing device, conveying device, sewing device and computer control. It is widely used in chemical raw materials, ash calcium powder, water reducing agent, dry mortar, feed, inorganic salt, industrial salt. , Lime powder, gypsum powder, pulverized coal, starch, mineral powder, raw powder, paint powder, putty powder, pigment powder, food, fertilizer, construction, building materials, metal powder, flour, additives, food, light industry and other industries Quantitative packing of materials. (Corrosive materials, packaging scales made of stainless steel)
At present, on the market, the quantitative packaging weigher feeding device mostly adopts a motor-driven double-screw feeder. In order to ensure the accuracy and speed of the control system, the double screw feeder has a large and small two-stage screw feed, and the initial state is at the stop position. When entering the automatic operation state, when the material weight reaches the large feed set value, the large feed motor is stopped and the small feed motor is continuously maintained. When the material weight reaches the final set value, the small feed motor is turned off. Due to the fluidity of the material itself and the mechanical inertia of the screw feeder, coupled with the uneven material transport, the dynamic accuracy of the quantitative packaging scale is difficult to control stably. Based on the above problems, we used the inverter to carry out technological transformation of the feeding device of the quantitative packaging scale, and changed the double screw feeder form into the single screw feeder form, which reduced the production cost and improved the quantitative packing scale. performance.
There are a large number of quantitative packaging scales on the market. It is recommended that when selecting a quantitative packaging scale, the latest technology of frequency conversion technology should be selected. The variable frequency feeding can allow the quantitative packaging scale to be refined to three feedings, which will be compared with the traditional double screw precision and speed. Greatly improve.
When selecting a quantitative packaging scale, be sure to specify to the manufacturer of the quantitative packaging scale that the characteristics of the material you are packing (granules or powders, material particle size or mesh number, moisture content, etc.), bag characteristics (bags) when you purchase this scale Whether the length, width, woven bag or kraft paper bag, your expected output, feeding method, and whether the site is limited are detailed information, don't be afraid of trouble. The more detailed the manufacturer asks, the more responsible they are to you, only the problem is clear. They can give you the best technical solution for you.
