The invention relates to a polar plate weighing device which comprises a weighing frame; a base plate is arranged in the weighing frame; a weighing sensor is arranged above the base plate along the transverse direction; one end of the weighing sensor is connected with the base plate by a cushion block; the other end of the weighting sensor is connected with a supporting bar; a tray is arranged atthe upper end of the supporting bar; and the weighing sensor is connected with a signal analysis display system in a communication way. The polar plate weighing device is suitable for weighing polar plates of storage batteries in the storage battery production process; and the weighing accuracy of the polar plate weighing device is higher relative to the common metering.

The invention discloses an automatic cotton core weighing device which comprises a cotton storage box and a cotton feeding box. The cotton storage box is in an inverted trapezoid shape, the upper portion of the cotton storage box is opened, and the cotton feeding box is arranged over the cotton storage box. The automatic cotton core weighing device is characterized in that a movable box bottom is arranged on the lower portion of the cotton storage box, the two sides of the movable box bottom are connected with guide rail devices, the movable box bottom can make front-back movement in the horizontal direction along guide rails, a weighing platform is further arranged above the movable box bottom, and a weighing sensor is fixed beneath the weighing platform. Consequently, weighing is more accurate, weighing errors are smaller than 1.5%, usage of raw materials can be well controlled, and finally product consistency is better guaranteed.

The invention provides a dynamic weighing filtering method and system thereof. The dynamic weighing filtering method comprises the following steps that step S1, continuous and equal-period sampling isperformed on the object weight on a conveying belt; step S2, the sampling result of the object weight is filtered so as to obtain the filtered weight value; step S3, the weight change slope is calculated according to the filtered weight value; step S4, the weighing state of the object is judged by the weight change slope; and step S5, whether a low-pass filter is applied to perform filtering is determined according to the weighing state and the final weight result is outputted. The movement characteristics of the object on the conveying belt can be met and the vibration noise and the weighingerror caused by movement of the object on the conveying belt can be effectively reduced; and the filtering process is fast in speed and high in accuracy, filtering is smooth and transition is stableso that the dynamic weighing process is enabled to be more stable and reliable and the accuracy and the working efficiency of dynamic weighing can be greatly enhanced.
