Bucket inner wall on-line self-cleaning device of packing scale

Abstract

The invention relates to a bucket inner wall on-line self-cleaning device of a packing scale, comprising a scale-bucket upper body, an upper fixed ring, a cleaning wheel, a scale-bucket lower body, a lower fixed ring, an axial rolling wheel, a radial spacing ring, a radial rolling wheel, a transmission case, a driving wheel, a motor and a scraper, wherein the cleaning wheel is supported on the scale-bucket lower body through the radial spacing ring, the axial rolling wheel and the radial rolling wheel and can freely rotate around the central axis of the scale-bucket lower body; the transmission case is fixed on the scale-bucket upper body and the scale-bucket lower body, the motor is fixed on the transmission case, the cleaning wheel is driven by the driving wheel, the scraper is fixedly arranged on the inner side surface of the cleaning wheel, and a dust scraping structure is formed between the scraper and the inner side surface of a bucket body. Because a scale bucket is designed into a split structure and the cleaning wheel is additionally arranged between the scale-bucket upper body and the scale-bucket lower body, when powder-containing adhesive materials are inputted to the scale bucket, because the scraper is driven to constant scrape along the inner side surface of the bucket body by the cleaning wheel, the device ensures that the materials to be packed are not stuck on the inner side surface of the bucket body, thereby ensuring the packing and metering accuracy.

Description

【Technical field】 [0001] The invention relates to a packaging machine for materials containing powders, in particular to a bucket-type packaging weighing scale for materials containing powders and other materials that are easy to stick to. 【Background technique】 [0002] When the existing packaging scale packs powder-containing materials that are easy to stick to, there is a sticking phenomenon of the material powder on the inner walls of the weighing hopper, the transition hopper, and the bagging hopper. When the scale hopper starts to weigh, there is no or a very small amount of sticky material on the inner wall of the hopper. After the weighing instrument automatically adjusts to zero and works normally, it can still weigh correctly, but after a period of time, with the sticky material If it exceeds the normal range of automatic zeroing of the instrument, there will be large or small deviations in weighing measurement, and there will be irregularities, which cannot meet t...

Problems solved by technology

[0003] The purpose of the present invention is to provide an online self-cleaning device for the inner wall of the bucket of the packaging scale. Under the premise of not affecting the normal operation of the packaging scale, it can automatically clean the inner wall of the bucket, and eliminate the damage caused by the sticky material on the inner wall of the bucket. The defect of low weighing measurement accuracy, there is neither noise nor vibration during the cleaning process, and it will not cause any damage to the load cell and mechanical equipment, ensuring the weighing accuracy of the packaging scale
