Brief introduction to the working principle of
????The linear combination weighs the material combination when packaging and the general speed can reach more than 60 bags / min, and the quantitative error can reach ± ??0.5%. Separate feeder first feeds the material into the hopper, the hopper and the weighing hopper form a weighing unit, the load cell sends the signal to the main processor for combined calculation, and then selects a better combined hopper for discharging.
????The working principle of linear combination:
????1. The material is sent to the storage hopper by the material conveyor. When the material is added to the preset horizontal orientation, the electronic eye on the side of the storage hopper detects and announces the signal, so that the conveyor stops feeding until the material on the storage hopper drops horizontal At the preset horizontal position, the electronic eye announces the feed signal again;
Linear combination
????2. The material is in the storage hopper, and the material from the main vibrating plate is evenly dropped into the line vibrating plate through the vibration of the main vibrating machine to feed each line vibrating plate;
????3. The vibration of the line vibrator causes the materials to be discharged from each line vibrating plate and enter the feed hopper for storage;
????4. When the weighing hopper completes the last weighing and emptying, the upper feed hopper is opened to make the material enter the weighing hopper for weighing. The output signal transmits the data to the main board of the control device through the lead wire. Record the weight of each weighing hopper, and then select a linear combination weighing hopper that is close to the policy weight through calculation, analysis, and combination.
????Feed hopper-adjust the delay time of the feed hopper in the program parameter setting A to ensure that the material in the feed hopper is completely added to the weighing hopper; if the time setting is too short, the feed hopper will clamp the material and weigh the hopper Multi-feeding means that after the feed hopper is opened, the line vibrating plate is started and the feed to the feed hopper is started.
????Weighing hopper-adjust the delay time of the weighing hopper in the program parameter setting A to ensure that the materials in the weighing hopper are completely added to the collection hopper or packaging machine (no collection hopper); if the time setting is too short, the weighing hopper When the weighing hopper is opened, the feeding hopper starts to feed the weighing hopper before the weighing hopper is opened, which will cause the collecting hopper to have more materials and the weighing hopper to clamp the material.
