Air exhausting and bag placing synchronous on-line device of packing scale and implement method

Abstract

The invention discloses an air exhausting and bag placing synchronous on-line device of a packing scale and an implement method. A fixed feeding pipe is arranged in a bag clamping device in a nesting mode, an air exhaust pipe which can not move penetrates through the middle of the feeding pipe, the upper end of the air exhaust pipe is connected with a draught fan, and the lower end of the air exhaust pipe is connected with a filter element through which only air can penetrate. An air exhaust opening is formed in the bag clamping device, and the bag clamping device can ascend and descend through a lifting mechanism and a guiding device. A packing bag is clamped on the bag clamping device and ascends and descends together with the bag clamping device, the bag is placed in a variable speed, and the packing bag can move relative to the air exhaust pipe and the feeding pipe. The device which is safe and environmentally friendly, and saves efficacy is designed for solving the problems that in the process of powder package, powder spills to pollute the environment, gas mixed in the powder enables the packing bag to expand to occupy the size to cause waste of packing materials, the bag bursts easily in the carrying process, the powder goes bad, the irregular bag shape affects the storage of the bag, and stacked bags slip and fall easily. The series motion combination of weighing, air exhausting and bag placing in the variable speed is achieved, the efficiency of the air exhausting is high, environment dust is little, the air content of the powder in the packing bag is small, the bag falling in the variable speed is stable, working intensity of taking the bag by workers is relieved, the bag does not fall, and the powder does not spill.

Description

technical field [0001] The invention discloses an online device for synchronously pumping and releasing bags and a realization method thereof, belonging to the technical field of packaging machinery. Background technique [0002] At present, in the powder packaging technology, there are the following defects: first, the flow, transportation, and whereabouts of the powder during the weighing and packaging process, and the whereabouts of the packaging bags that have not been seamed after the weighing will cause dust to overflow, which will affect the working environment. Bring pollution, and can cause dust explosion; second, the air in the bag reduces the volume utilization rate of the packaging bag, wastes the packaging bag and causes the bag to burst when the inner film of the packaging is squeezed during handling and palletizing, resulting in a loss of the net weight of the material. Reduce and pollute the environment, the material in the bag absorbs moisture and deteriorat...

[0002] At present, in the powder packaging technology, there are the following defects: first, the flow, transportation, and whereabouts of the powder during the weighing and packaging process, and the whereabouts of the packaging bags that have not been seamed after the weighing will cause dust to overflow, which will affect the working environment. Bring pollution, and can cause dust explosion; second, the air in the bag reduces the volume utilization rate of the packaging bag, wastes the packaging bag and causes the bag to burst when the inner film of the packaging is squeezed during handling and palletizing, resulting in a loss of the net weight of the material. Reduce and pollute the environment, the material in the bag absorbs moisture and deteriorates, and the gas in the bag makes the bag shape irregular and easy to slip when stacking, causing the bag stack to collapse and be unsafe
