A kind of advanced quantitative weighing

A kind of advanced quantitative weighing and packaging equipment -- Jingwei computer combined scale, multi head scale the origin of the computer combination scale the computer combination scale is also known as the selective combination weighing instrument. It is composed of multiple weighing units with independent feeding and discharging structure, and the general computer combination scale is composed of 8-32 weighing units. The computer uses the principle of permutation and combination to automatically optimize and calculate the load of each weighing unit. The combination of Zui Jia and Zui close to the quantitative value is obtained for packaging. As shown in the figure, for example, for a computer combined scale Multihead Combination Weigher with ten weighing units, each weighing unit is weighed during weighing, and the weight data in each weighing bucket is read into the computer, and the computer carries out optimal combination. According to the combination number, ten weighing units can realize 1023 combinations, and the computer selects the combination from which Zui is close to the target weight value. In this way, the above artificial repeated collocation and it is difficult to realize the quantitative value of the work can be easily solved. 2. The technical advantages and features of the computer combined scale are 1 High weighing accuracy the computer combined scale can ensure the weighing accuracy from the following three aspects: A, secondary sampling for example, in the weighing process, the computer reads the data from the ten weighing units once as * times of sampling, and the computer obtains the data to optimize the combination; if the three weighing units are weighed, the three weighing units are selected again The weight data of the weighing unit is sampled once, which is the second sampling; if the data of the two sampling are inconsistent, the computer will combine again,If the data of the two sampling are consistent, the computer combined scale will discharge the material, so as to ensure that the weight of the discharged material is completely consistent with the predetermined weight. b. Automatic zero setting function because some of the weighed dust will stick to the wall of the weighing bucket during the weighing process, which will affect the accuracy of the next weighing. The solution to this problem is as follows: 1) when releasing materials, the weighing hopper should be opened 4-5 times, so as to reduce the residual dust. ② The computer combined scale will automatically return the weight of the weighing bucket to zero, that is, the dust adhered on the weighing bucket is regarded as zero weight, which does not affect the accuracy of the next weighing. c. Anti ground vibration the general computer combination scale works in the workshop, and there are often power motor equipment running in the workshop to produce vibration on the ground, the human body generally can not feel this kind of vibration, but for the high sensitivity computer combination scale, the weighing data will be unstable. Therefore, the computer combined scale adds an inductive vibration sensor in addition to the weighing sensor The device can remove the vibration component from the data of the weighing sensor, so as to obtain reliable data. Digital signal processing technology 2. Fast weighing speed A. digital signal processing technology the digital processing of the computer combined scale is completed by a special computer chip, which ensures that the weight analog signal is converted into digital signal after fast digital filtering, thus ensuring that there is time to complete the "secondary data sampling" function mentioned above. b. The stepping motor controls the opening and closing of the hopper due to the controllability of the stepping motor, the opening and closing speed and size of the weighing hopper can be adjusted, and the opening and closing speed of the weighing hopper can be adjustedWhen weighing, the opening and closing of the weighing hopper can be adjusted to a small value to achieve high speed. c. The feeding vibration groove is adjustable the amplitude and vibration time of the vibration groove can be adjusted, and the adjustment is fine, which can meet the requirements of accuracy and speed. Another important feature of the computer combined scale is that it has corresponding application technology according to different materials, such as waterproof type, fragile type, sticky type, mixed weighing, number weighing and so on, which can meet the needs of all aspects. the birth of the computer combined scale has created a new era of quantitative packaging in the world.
