Agent: Liu Ya Wu Zhengang Abstract The utility model discloses an automatic quantitative packing weigher, which adopts a two-stage feeding method, a visual hopper, a straight pull type door opening mechanism and a duckbill type clamp bag mechanism, and is particularly suitable for granular and fluidity. Quantitative filling of materials. It has the advantages of wide range, stable feeding, small impact force, high quantitative accuracy, fast canning speed, simple and convenient operation, and stable and reliable work. The utility model consists of a main support frame, a feeding device, a weighing device, a bag clamping device and a display control unit. The feature is: the feeding device is a glass window hopper 1; the weighing bucket 4 inlet and outlet of the weighing device adopts two straight pull type door opening mechanisms; the bag clamping device is a cylinder 7 Drive duckbill clamp mechanism 6 . The utility model has the advantages of stable measurement, high accuracy and improved filling speed. Particularly suitable for use in food, fertilizer production, chemicals, food, metallurgy building materials and abrasives and other industries. Sovereignty item 1. An automatic quantitative packaging scale consisting of a main support frame, a feeding device, a weighing device, a bagging device, and a display control unit; and characterized in that: the feeding device is a glass window storage hopper (1) A transparent material (12) is installed on the storage hopper; the weighing device includes two straight pull-outs of a metering bucket (4), a load cell (9) and a feed inlet and outlet of the weighing bucket (4). The opening mechanism; the weighing hopper (4) is located below the storage hopper (1), the bottom surface of which is an inclined bottom surface, and the storage hopper (1) is at the outlet of the storage hopper direct-pulling type door opening mechanism (2), and the lowest point of the weighing bucket (4) The discharge port is a metering bucket pull type door opener (5). The slide door (11) of the straight pull type door opener slides on a horizontal groove slide (10), and the slide door (11) is controlled by an electronic control part. The pneumatic cylinder 3 and the cylinder 8 are driven; the bag clamping device comprises a duckbill clamp mechanism (6) driven by a pneumatic cylinder (7), and two symmetrical movable clamps (13) are opened around the rotary shaft (12) or Helong, the movable shaft and cylinder of the cylinder (7) are respectively connected with two movable jaws (13), and the open positions of the movable jaws are pressed to the two internal eight shapes welded under the main support frame (16). Fixed baffles (14).
