Description

Technical Field

[0001] The utility model relates to the field of material packaging devices, in particular to a continuous bag placing device. Background Art

[0002] The packing process is an important part of the production of emulsion explosives. In the past, this process mainly relied on manual operation, which was inefficient and difficult to ensure the safety of production personnel. With the advancement of automation technology, many manufacturers have gradually adopted fully automated or semi-automatic equipment to replace manual packing operations, which has significantly improved the efficiency and accuracy of the emulsion explosive packing process. The current emulsion explosive packaging equipment usually uses a grabbing device to grab the produced medicine rolls and put them into the packaging box. When the packaging box is full, it will be transported to the bag placement position through a conveyor, and then the operator will manually put the middle bag into the packaging box. The packaging box will then continue to be transported to the sealing device to complete the sealing operation. However, this process still requires the operator to manually place the bag, which not only increases the workload, but also increases the labor intensity, thereby affecting the efficiency of bag placement.
