Combination said that it meets the actual needs
The initial application of the combination weighing system is only used for the weighing of agricultural products, and it has gradually expanded to snacks, processed meats, confectionery, crispy foods, quick-frozen foods, metal and rubber parts, and even pharmaceuticals. The structure and control system of the combination weighing system also include Simple mechanical weighing, only the weighing bucket is gradually developed to use a weighing sensor, and the weighing analog signal is converted into a digital signal for combined calculation. The standard multi-head microcomputer combination scale is constantly improved and boldly innovated. It has now served high-speed development. Modern industry.
The basic structure of the multi-head microcomputer combination weigher is: main vibration plate, main vibration machine, line vibration plate, line vibration machine, feed hopper, weighing hopper, chute, collecting hopper (optional), stepper motor, drive board, Module conversion device, main control board.
Multi-head microcomputer combination weighing device is also called selective combination weighing instrument. It is composed of multiple weighing units with independent feed and discharge structure. Generally, multi-head microcomputer combination weigher is composed of 8 to 32 weighing units. The computer uses the principle of permutation and combination to automatically and optimally calculate the weight values of each weighing unit to obtain a better combination close to the preset target weight value for packaging. For example, a computer combination weigher with ten weighing units, each weighing unit weighs during weighing, and reads the weight data in each weighing hopper into the computer, and the computer performs the optimal combination according to the combined number The 10 weighing units can realize 1023 combinations in total, and the computer selects the combination that is close to the target weight value from these 1023 combinations. In this way, it is easy to solve the work of manual matching and it is difficult to achieve quantitative values, which meets the actual needs of modern packaging industry to adopt quantitative packaging.
At present, there are various combinations of combination weighing manufacturers on the market. According to the number of weighing hoppers, weighing accuracy, the achievable weighing packaging speed range, the requirements of the use environment and other parameters, there can be different combinations of weighing products, users can According to the volume of the weighed material, it is often necessary to weigh the accuracy requirements of the weight, and the actual conditions of the existing plant, etc. to select the appropriate combination weigher.
