Description

Technical Field

[0001] This utility model belongs to the field of composite plastic woven bag technology, and particularly relates to a cutting device for composite plastic woven bags. Background Technology

[0002] Composite plastic woven bags are an important packaging material. They are made by bonding woven plastic fabric with other materials through casting or other composite processes. These bags are usually used to package powdery or granular solid materials and flexible items.

[0003] During the processing of woven bags, the woven bag material needs to be cut into appropriate sizes and then sewn together. In order to prevent the woven bag material from loosening after cutting, a hot cutter is used to cut the material. Due to the stickiness of the woven bag material itself, it will stick at high temperature, causing residue to stick to the blade surface. Long-term adhesion of residue will lead to accelerated blade wear and reduce the service life of the blade. Utility Model Content
