Abstract

The invention relates to a crimping device for a sewing machine with a thread trimming function comprising a crimping plate, a connecting plate and a mounting plate; the front end of the crimping plate is provided with an arc plate A which overturns downwards; the left side and the right side of the crimping plate turnover inwards and downwards to form crimping grooves; a fixing plate is installed between the crimping grooves at the left side and the right side of the crimping plate; the front end of the fixing plate is provided with an arc plate B which overturns upwards; the arc plate B is positioned under the arc plate A; a gap zone is installed between the arc plate A and the arc plate B; a shear blade is provided between the front end of the crimping plate and the front end of the fixing plate; the left side of the crimping plate is connected with the connecting plate; the connecting plate is connected with the mounting plate; the mounting plate is provided with a mounting groove. The crimping device of the invention has the trimming function to facilitate the shearing of the thread ends after the crimping sewing; the device has simple operation and high safety and is not liable to injure hands.

Description

technical field [0001] The invention belongs to the technical field of garment processing devices, and in particular relates to a sewing machine curling device with a thread trimming function. Background technique [0002] At present, when fabrics are sewn, the edges of the fabrics are often rolled up and sewn to prevent roughness and appearance. In addition to using a special edge prying machine, there are also sewing machines. When using a sewing machine to sew fabrics with hemming, a hemming device is required. After sewing with a sewing machine, it is often necessary to use scissors to cut the sewing thread. It is comparatively loaded down with trivial details to bend over to pick up, and existing crimping device does not have thread trimming function. Contents of the invention [0003] The present invention aims at the disadvantage that the crimping device in the prior art has no thread trimming function, and provides a crimping device for sewing machines with a thre...
