Which weightless scale is better
We all know that the weightlessness scale is a kind of weighing equipment with intermittent feeding and continuous discharging in the production workshop, which can improve work efficiency, check defective products, and provide product quality. So which weightless scale is better, here is definitely the quality of the weightless scale. First, let's talk about the working principle of the weightlessness scale, and then look at the main working parts of the weightlessness scale. The weight of the material in the weighing hopper is converted into an electric signal by the weighing sensor and sent to the weighing instrument. The weighing instrument compares and judges the calculated material weight with the preset upper and lower weight limits, and controls the input by PLC. The feed gate feeds the weighing hopper intermittently. At the same time, the weighing instrument compares the calculated actual feeding rate (discharge flow rate) with the preset feeding rate, and uses PID adjustment to control the discharging device so that the actual feeding rate accurately tracks the set value. . When the feed gate is opened to feed the weighing hopper, the control signal locks the feed rate and performs volumetric discharge. The weighing instrument displays the actual feed rate and the cumulative weight of the discharged material. Weigh the discharging device and the weighing hopper, and compare the actual feeding rate with the set feeding rate according to the weight loss per unit time, so as to control the discharging device so that the actual feeding rate always accurately conforms to the setting In the short-time feeding process, the discharging device uses gravity to make the control signal stored during the working period work according to the volumetric principle. Through the above content, we can well analyze: weighing sensor, weighing terminal, controller, inverter, touch screen Guangdong kenweigh weightlessness scale combines all the advantages into one, simple structure, compact, small size, convenient installation and maintenance, belt Protective lock block, quick split structure, hoop type connection, lightweight gear box, spherical hopper, all parts in contact with the material are made of stainless steel.
