線的包裝系統(tǒng)是洗衣粉生產(chǎn)的最后一道工序，產(chǎn)品包裝質(zhì)量 的優(yōu)良直接影響到產(chǎn)品在顧客心中的地位和對產(chǎn)品 的定位。 關鍵詞 ： 洗衣粉，包裝控制， 重量控制， 容積 主加料法 ， 靜態(tài)稱重 補加料 法 洗衣粉填充加料系統(tǒng)的設計 II ABSTRACT Weight control system is the important position part of modem packing control system,its technology is one of indispensable crucial technologies of packing control technology,its control effect directly affects the amount of the quality of product, the precision of product and paper aims to the WashPowder packing tache,and it analyses and studies according to the structure and principium with the JINYI packer,and it analyses the new type technique of filling and measuring by bining two methods(one is the method of the main filling by cubage,and other one is the method of the supplementing by static weighing up).This paper is based on the material electric connecting drawing,and last it gives the structure drawing of the controlling according to the main filling and supplementing. KEY WORDS:WashPowder。packing control。在包裝中又分為產(chǎn)品外觀和產(chǎn)品重量兩大組成部分。小袋送到捆扎皮帶裝大袋，包裝好的大袋在粘貼合格證后被送至庫房入庫。 在整個包裝工藝流程中，填充計量系統(tǒng)是最核心的部分之一 ， 填充計量的穩(wěn)定性、精確性和快速性 綜合 反映了 包裝 生產(chǎn)能力水平。 ?導料體 導料體位于上叉管和變?nèi)萃仓虚g，完成上叉管和變?nèi)?筒的過渡連接。 ?減振支架 減振支架的主要作用是整個主加料系統(tǒng)與補加料系統(tǒng)運動機構的支承，通過前面四個大減振器與補加料安裝底板下的兩塊減振墊完成將振動源與稱重體的隔離，確保稱重的穩(wěn)定 。傳感器把重量數(shù)據(jù)送到計算機以進行組合選擇計算。每個菜單都有操作鍵。遙控器裝于颶風雙星右下面的齊肩高
