Description

Dynamic checkweigher Technical Field The utility model relates to a dynamic checkweigher which is used for accurately weighing materials in the conveying process. Background Conveying equipment such as belt conveyors, screw conveyors and the like are commonly used in industries such as express delivery, food packaging, chemical batching, mining industry and the like, and the material is inevitably required to be weighed in the conveying process. One obvious disadvantage of the multi-sensor type dynamic checkweigher used in the market is that the accuracy is too poor, and various factors influence the accuracy of the dynamic checkweigher, wherein the following three points are greatly influenced: 1. Taking four sensors as examples, the four sensors cannot be absolutely arranged on the same plane due to the influences of processing errors and welding deformation, and have certain distance and angle errors, so that the stress among the sensors is overlarge after the four sensors are arranged, the precision is reduced, and the welded underframe inevitably deforms along with the time to cause the situation to be more serious; 2. Vibration affects, the dynamic weight balance is theoretically that the conveyor continuously conveys materials, the materials are weighed in the conveying process, the vibration of the conveyor in the running process is affected by stress, and the weighing precision loss is aggravated; 3. The reaction force when the material initially reaches the conveyor is influenced, when the material arrives on the conveyor, the motion state of the material changes (possibly accelerates and possibly decelerates), and the reaction force is inevitably generated, which is also a significant factor influencing the accuracy of the dynamic checkweigher. Due to the influence of various factors, the traditional dynamic checkweigher has poor precision, so that the conveyor has to be stopped for weighing, the production efficiency is greatly reduced, and the weighing precision requirement is not high. Disclosure of Invention Aiming at the defects in the prior art, the utility model provides the dynamic checkweigher, which can avoid the problem of stress between sensors caused by processing and welding errors, reduce the influence of vibration of a conveyor on weighing precision and improve the dynamic weighing precision of the dynamic checkweigher.
