The principle of computer combination scale

Introduction: The main reason of the computer combination scale is to apply the principle of combination weighing. Computer combination scales include 8-head scales, 10-head scales, 12-head scales, 14-head scales, 16-head scales, 24-head scales and more, each of which is a separate scale that can be weighed independently. What is a multi-head scale? Multi-head combination scale, also known as combination weighing instrument, is used for rapid quantitative weighing of granular, strip, and irregular materials. It is composed of multiple independent weighing units for feeding and discharging. The weight module changes the elastic deformation of the weighing unit of the pressure sensor into the component value and stores it in the register. The CPU uses the principle of permutation and combination to automatically optimize the component value of the weighing unit to calculate the best and closest target component. The component combination of value stops blanking. Combination scale composition: 1 long feeding hopper 7 driving equipment (stepper motor) 2 material photoelectric detection switch 8 feeding chute 3 main vibration plate (main vibration machine) 9 collecting hopper 4 wire vibration plate (linear vibration head) 10 electromechanical drive board 5 Storage hopper 11 Main board 6 Weighing hopper 12 A/D module combination weigherThe working principle: 1. In the long feeding hopper, the material is vibrated by the main vibrating disc, so that the material spreads the product on the conical funnel into the linear vibrating disc. 2. When there is no or insufficient material in the line vibrating plate, it will be detected by the material weighing module, which is to send the feeding signal to the main board, and then send the feeding signal to the material conveyor through the main board to feed the material until it reaches the test. until the material is available. 3. The line vibrating machine vibrates, activates the line vibrating disc to vibrate, adjusts the appropriate amplitude and vibration time, and sends a certain amount of material to each storage hopper. 4. The driving equipment is the stepper electromechanical work, close the door of the storage hopper, and send the material to the weighing hopper. When there is no material in the weighing hopper above or when the material in the weighing hopper is not enough, the storage hopper will automatically open the door and put the material into the weighing hopper. in the fight. 5. In the weighing bucket, the weight signal is generated by the sensor, and then transmitted to the main board of the control device through the lead wire. The CPU on the main board reads and records the weight of each weighing bucket, and then calculates and analyzes it through the process. , combination, filter out the combination weighing bucket closest to the target weight, when receiving the request signal from the packaging machine to discharge, the CPU returns the signal to start the electromechanical driver of the weighing bucket and closes the selected weighing bucket. Unload it into the unloading trough and enter the packaging machine (if there is a collection hopper, put the estimated collection hopper directly after the weighing hopper is assembled, and start the collection hopper electromechanical to discharge the material to the packaging machine when there is a request signal for discharging). 6. When the weighing hopper (collecting hopper) is finished with the material, the combination scale will send a discharged signal to the packaging machine. After receiving the discharged signal, the packaging machine will seal and cut the bag to the open end. When the packaging mechanism After a bag is finished, a request signal is sent to the combination scale for unloading, which is called the combination scale unloading, and so on. Important advantages of multi-head combination scales: 1. The machine automatically weighs, which is beneficial to food safety 2. 3. Weighing rate is fast. 4. High precision of static weighing. The application range of the multi-head combination scale with high automation level: suitable for rapid quantitative weighing of various types of granular, flake, strip, spherical and other irregular materials. Such as candy, fruit (raisins, dates...), nuts (walnuts, pistachios...), pet food, roasted seeds and nuts (melon seeds, peanuts...), puffed food (potato chips, shrimp sticks...), frozen food (glutinous rice balls, dumplings...) ...), hardware, plastic pellets and other manufacturers that need quantitative weighing. Why do multi-head combination scales get the special attention of various food companies? The use of computer 10-head combination weigherfor quantitative weighing is compared with the use of ordinary electronic scales to achieve the same thing. Adopt computer 10-head combination scale: 10-head computer combination scale is required, 1 operator is required, the rate is 60 bags/min, the deviation per bag is 0.3~0.5 grams, the total deviation per day is about 8 kg, and the total deviation per year is about 3 tons ; Adopt the usual electronic scales: 5 units are required, 5 operators are required, the speed is 12 bags/min, the deviation of a single bag is 2 grams, the total deviation per day is 57 kg, and the total deviation per year is 20 tons. Obviously, the use of computer combination weighing can save 4 labors and 17 tons of materials for manufacturers every year. It is not difficult to see that choosing a multi-head combination scale is an eye-catching choice for businesses.
