Description

[0002] Glyphosate is an effective active chemical ingredient in many widely used herbicides. Glyphosate has no direct relationship with genetically modified crops. Non-genetically modified crops also need to be sprayed with the herbicide glyphosate. In the production process of glyphosate, packaging machines are needed to carry out necessary packaging processing of glyphosate materials.

[0003] However, the existing packaging machines used for glyphosate production are usually small bag packaging, and the existing small bag packaging equipment is not suitable for large bag packaging. The small bag packaging material is directly packaged on the packaging machine after the coil is folded, and the large bag cannot be installed with large-size coils due to size reasons. Therefore, it is necessary to load the large bag packaging material that has been processed in advance. In addition, the loading of the packaging material during the large bag packaging process lacks positioning, which easily leads to crooked bags, causing the packaging material to tilt and affect bagging. When the product is discharged, the connecting surface of the large bag packaging material is in the same direction as the conveying direction, which will cause the position of the product on the conveyor belt to be uncertain, and the poor consistency affects the subsequent packaging.
