Louver shape cutter and cutting machine used for sewing industry

Abstract

The invention provides a louver shape cutter and a cutting machine used for the sewing industry. The louver shape cutter comprises an upper cutter blade (10) and a lower cutter blade (20). The upper cutter blade (10) comprises two cutter feet (11 and 12). A protruding unidirectional inclined cutting edge (15) is arranged between the two cutter feet (11 and 12). An included angle alpha is formed between the plane where the unidirectional inclined cutting edge (15) is located and the horizontal line, and alpha is 10-20 degrees. The lower cutter blade (20) comprises two cutter feet (21 and 22). A linear unidirectional inclined cutting edge (25) is arranged between the two cuter feet (21 and 22). An included angle alpha is formed between the plane where the linear unidirectional inclined cutting edge (25) is located and the horizontal line, and alpha is 10-20 degrees. The cutter provided in the embodiment can be applied to the sewing industry, louver shapes can be cut in manufactured products in garment factories, shoe factories, bag factories and the like, and the cut louver shapes are flat and not prone to deformation.

Description

technical field [0001] The invention relates to a tool accessory for a tape cutting machine, in particular to a louver-shaped cutter and a cutting machine used in the sewing industry. Background technique [0002] Shutters are a style of windows that originated in China. In ancient Chinese architecture, there are mullion windows, which were used in all dynasties from the Warring States Period to the Han Dynasty. shutter shape (eg figure 1 shown) is mainly used in decorative furniture, such as windows, cabinets, etc., not only beautiful, energy-saving, simple and neat, but also because of its unique structure, it can effectively prevent insects, birds or other light objects from entering the room, so it is widely used in computer rooms, Office buildings or other related occasions. [0003] At present, in the products provided by the sewing industry, such as clothing, shoemaking, and bag factories, for the sake of aesthetics and air permeability, some air hole structures ar...

AI Technical Summary

Problems solved by technology

However, the existing air-vent structure is common and easy to inhale external dust while ventilating, making the interior of the product unhygienic and difficult to clean

And if adopt the venting hole of louver shape, because the ventilating structure of louver is not parallel, but has the structure of certain inclination, then be easy to solve above-mentioned problem, but still do not have a kind of louver shape cutting knife to be applied in the sewing industry at present
