5results about How to "Reduce weighing errors" patented technology

The application provides a cross-border parcel declaration consistency verification system and method based on a multi-point dynamic weighing device. It belongs to the field of logistics automation and intelligent weighing technology. The method comprises the following steps: reading the cross-border parcel identification code through a parcel identification device, calling the declaration weight value associated with the identification code from the declaration database, and generating parcel declaration reference data; based on the conveying belt conveying speed parameter and the parcel size distribution characteristics, a plurality of pressure sensors are arranged along the longitudinal direction of the conveying belt, the moving parcel is continuously sampled for pressure signals, the dynamic noise interference is removed through sliding window filtering processing, the instantaneous weight value is calculated combined with the calibration parameters of each sensor and weighted fusion, and the parcel dynamic weight value is generated; through the fusion of the multi-point dynamic weighing device and the intelligent grading disposal mechanism, the cross-border parcel customs efficiency is significantly improved, the online full coverage detection of the moving parcel is realized, and the low efficiency problem caused by the traditional static weighing which needs to stop the line to take the parcel is avoided.

The utility model relates to a kind of air bag type simple packing machine suitable for different specifications ton bag of packing machine technical field, including supporting leg, mobile platform, feed dust hood and height adjusting structure, one end of feed dust hood is connected with bag clamping structure, the surface of mobile platform is equipped with hook structure, this simple packing machine does not have metering system, and low-cost metering structure such as ground weight is used to realize metering function, the structure reduces the vibration caused when operating to cause the error of weighing;Hook structure fixed position can be adjusted, suitable for ton bag of different specifications, improve work efficiency;Height adjusting structure includes different height position has pinhole, realize simple packing machine height adjustable, bag clamping structure uses air bag type, widened air bag fixing ring seat, increase contact area, improve bag clamping structure stability, while effectively handle the problem of powder leakage, while self-contained exhaust filter, can assist discharging, can effectively filter dust, avoid environmental pollution.

The utility model is suitable for powder distribution technical field provides a kind of high-precision powder metering distributor, including;Support frame;Touch screen, the touch screen fixed mounting is at the front side of support frame bottom;Positioning frame, the positioning frame fixed mounting is at the front side of support frame top;Placing frame, the placing frame is movably inserted in the middle part of positioning frame;High-precision weighing sensor, the high-precision weighing sensor array is placed in the bottom of placing frame, and side surface is correspondingly provided with object weight display screen.Compared with prior art, the utility model has the beneficial effects that: in use, by setting centrifugal structure on positioning frame, and then the corresponding cup in placing frame is rotated, so that centrifugal force is generated in the cup, and then the powder in the cup is flattened, so that it is convenient, and the high-precision weighing sensor can carry out high-precision weighing to the powder in the cup, and then the appearance of weighing error is reduced.

The application belongs to the technical field of agricultural research and silage feed experimental research, and discloses a standardized quantitative silage raw material mixing experimental instrument, which comprises a treatment bin and a plurality of storage bins, the storage bins are arranged on the top surface of the treatment bin, a pressure monitoring control module and a feeding assembly are arranged in the storage bins, and the pressure monitoring control module is electrically connected with the feeding assembly; a partition is arranged in the treatment bin, a mixing assembly is arranged on the top surface of the partition, a pressing assembly is arranged on the bottom surface of the partition, a fixing ring is arranged at the top end of the pressing assembly, a plurality of frustopyramidal shapes are arranged on the fixing ring, and the frustopyramidal shapes are matched with through holes on the partition; a connecting cylinder is arranged at the bottom end of the treatment bin, and a collecting tank is arranged on the connecting cylinder; a plurality of raw materials can be stored in the plurality of storage bins, the feeding assembly is controlled by the pressure monitoring control module, accurate quantitative feeding is realized, and the mixing, transfer and pressing of the raw materials are automatically completed by the mixing assembly and the pressing assembly, so that the burden of the staff is reduced.

The utility model relates to a kind of weighing device of feeding box, the utility model is through the structure of "built-in weighing device+cover protection", solve the problem that traditional weighing assembly is exposed to dust, material pollution, leading to detection precision decline, service life shortening;Meanwhile through the "L type board sliding slot+slider" guide structure, limit the lateral deviation of aggregate bin in the process of bearing or discharging, avoid to intensify weighing error due to position swing, applicable to the industry of high requirement to material quantity precision control such as feed, food etc..Through the structure of "built-in weighing device+cover protection", solve the problem that traditional weighing assembly is exposed to dust, material pollution, leading to detection precision decline, service life shortening;Meanwhile through the "L type board sliding slot+slider" guide structure, limit the lateral deviation of aggregate bin in the process of bearing or discharging, avoid to intensify weighing error due to position swing, applicable to the industry of high requirement to material quantity precision control such as feed, food etc..
