Bag feeding device with air blowing structure

Abstract

The invention discloses a bag feeding device with an air blowing structure. The bag feeding device comprises a first conveying mechanism, a second conveying mechanism, a bag feeding mechanism and an air blowing mechanism. The first conveying mechanism comprises a first conveying wheel, first conveying driven wheels and a first conveying belt. The second conveying mechanism comprises a second conveying wheel, second conveying driven wheels and a second conveying belt. The bag feeding mechanism comprises a track box, an attraction module and a bag feeding piece. The air blowing mechanism comprises air blowing nozzles, an air pipe and an air pump. The air blowing nozzles are provided with air blowing holes and arranged in front of the second conveying wheel. The air blowing holes obliquely blow air outwards. One end of the air pipe is connected with the air blowing nozzles, and the other end of the air pipe is connected with the air pump. By means of the bag feeding device, a bag opening of a bag is kept in a closed straight state under the action of the air blowing mechanism, and interference is not likely to occur in the conveying process; and the bag feeding success rate is increased, and stable running of the device is guaranteed.

Description

technical field [0001] The invention relates to the technical field of sanitary napkin packaging, in particular to a bag feeding device with an air blowing structure. Background technique [0002] In the sanitary napkin production line, the sanitary napkin is clamped between its blades by the unscrambler, and the sanitary napkin is pushed out from between the blades of the unscrambler by the push head. The quantity pushed out each time is the quantity of a small package, which is called The pushed out sanitary napkins are sent to the chain mechanism, and then sent to the packaging device through the pallet mechanism. Before packaging, the packaging bag is sent to the packaging device by the bag feeding device. In the prior art, before the bags are fed, the mouth of the bag is often opened for bags made of relatively hard materials. During the process of absorbing and conveying the bags on the conveyor belt, the opened bags interfere with the rollers, which may cause the fail...

Problems solved by technology

In the prior art, before the bags are fed, the mouth of the bag is often opened for bags made of relatively hard materials. During the process of absorbing and conveying the bags on the conveyor belt, the opened bags interfere with the rollers, which may cause the failure of bag feeding and cause the machine to fail. Shutdown; for soft bags, before entering the rollers, both sides of the bags droop, which also interferes with the rollers, resulting in bag feeding failure
