Patent Name Suction Type Dust Packing Machine Patent Applicant Zheng Kaitao Principal Applicant Address 225600 Gaoyou City Nanjiao Economic Development Zone Gaoyou City Kaida Machinery Co., Ltd. Inventor Zheng Kaitao Application (Patent) No. 200420079836.7 Application Date 2004.09.27 Certification Date Auditing Announcement No. 2744600 Auditing Notice Day 2005.12.07 Manual CD-ROM D0549 Main Classification No. B65B1/28 Classification No. B65B1/28; B65B1/26; B65B1/00 Division Original Application No. Priority Item Abstracts Suction type dust-free packaging machine involves Powder packaging technology. The utility model comprises a hopper and a weighing sensor arranged on a frame, the weighing sensor is connected with a sealed weighing hopper, and a feeding tube passing inside and outside the weighing hopper is horizontally arranged on the weighing hopper, and is connected at the lower end of the hopper. The butterfly type bulk material finishing gate valve is connected with a hose between the butterfly type bulk material finishing gate valve and the feeding pipe, and the weighing hopper is connected with a vacuum pump through the pipeline. The utility model realizes suction feeding through a vacuum pump, without auger feeding device, it is not easy to cause material blocking, reduces mechanical abrasion, makes the production dustless, ensures environmental health of the production phenomenon, and also saves production cost. Sovereign item 1, suction type dust-free packaging machine, including a hopper and a weighing sensor arranged on a rack, characterized in that a weighing sensor is connected to a sealed weighing hopper, and horizontally disposed on a weighing hopper Feeding the feed pipe inside and outside the bunker, connecting the butterfly bulk material finishing gate valve at the lower end of the bunker, and connecting a hose between the butterfly bulk material finishing gate valve and the feed pipe, and the weighing bunker is connected with a vacuum pump through the pipeline. .
