Sewing Machine Knife Grinder

Abstract

The invention provides a sewing machine cutter sharpening machine and belongs to the technical field of machinery. The problem that an existing sewing machine cutter sharpening machine adopts an independent motor as a power source and accordingly is high in cost and non-adjustable in sharpening angle is solved. The sewing machine cutter sharpening machine comprises a housing and a spindle penetrating into the housing, wherein the spindle is connected with a sharpening wheel located outside the housing through a connecting structure, the housing is a sewing machine housing, the spindle is a sewing machine crank shaft, supporting plates located on the sides of the sharpening wheel are fixed to the housing and are provided with a blade placement plate located at the front portion of the sharpening wheel, an adjusting structure I for adjusting an inclination angle of the blade placement plate is arranged between the blade placement plate and the supporting plates, a positioning structure for positioning a cutter is arranged on the blade placement plate, and an adjusting structure II for adjusting a deflection angle of the cutter is arranged between the positioning structure and the blade placement plate. The sewing machine cutter sharpening machine has the advantages of being low in cost and capable of meeting the special angle requirements of a cutting blade.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a blade grinder, in particular to a sewing machine cutter grinder. Background technique [0002] Any knife will have a certain passivation after being used for a period of time, and it must be ground to ensure its sharpness. However, among commercially available grinding machines, although traditional manual grinding plates and grinding rods can handle all kinds of knives, it is difficult to do everything by manual operation. It is time-consuming and labor-intensive to use, and it is easy to cause muscle soreness or accidental injury to the user. For cutting cloth The shape angle of the knife is also difficult to control. Automatic grinding machines are usually suitable for medium and large knives, but not suitable for small blades such as sewing machine cloth cutting knives that have special angle requirements for shape. At the same time, the clothing sewing process has high r...
