A kind of cutting of the tailoring technique for cutting low melting material
Technical field
This utility model is related to technical field of textile machine and in particular to a kind of cutting skill for cutting low melting material
The cutting of art.
Background technology
At present, traditional numerical control cutter cutting meltable soft fabric when, cut-off knife in fabric high speed concussion with
High heat produced by fabric friction does not distribute not go out, and produces hyperpyrexia, thus melting meltable soft fabric.
In order to solve the above problems, in prior art, general solution is to reduce the cutting fabric number of plies, but so makes
The cutting number of plies less than hundred layers it is impossible to meet the needs of current cutting batch, limit numerical control cutter work efficiency and
The ductility of work.
At present existing Cutting Shear Knife cooling means be cooling pump cold air through the universal cooling tube of plastics against cutterhead
Blow cold air and reach the effect of cooling knife.Because of cutterhead rotation, cooling tube air outlet is relatively fixed, but with cut-off knife have certain away from
From the cold air of air outlet is that diverging air-out is not concentrated, and cut-parts are dispelled by lateral briefing, and temperature is with the increase of distance
And raise and can not lower the temperature very well, the unfavorable factor that this brings affects cutting work on the contrary.
Chinese patent CN 104032560 A discloses a kind of cutting cutter head, including a cutterhead box, described cutterhead box
Including diapire and side wall, described diapire and side wall enclose formation cutterhead box receiving space, and a cut-off knife may be installed described shearing knife
