Description

A prevent melting cutting bed for tailorring multilayer cloth
Technical Field
The invention belongs to the technical field of textile machinery, and particularly relates to an anti-melting cutting bed for cutting multilayer cloth.
Background
The whole roll of cloth needs to be cut into a plurality of pieces of cloth with the same length before sewing. The existing cloth is mainly cut in two modes, one mode is automatic cutting by laser, and although the mode can be used for accurate and quick cutting, the cloth is easily burnt, and resources are wasted. In addition, when a cutter is used for cutting a multilayer fabric continuously and frequently, due to frequent friction between a cutter edge and the fabric, the temperature of the cutter is easily too high, especially synthetic fibers are easy to cause phenomena of scorching, adhesion and the like of the edges of the garment pieces at high temperature, and the blade is stained. This not only influences back cutting, and the adhesion of multilayer cloth brings a lot of troubles to the clothing preparation of later stage.
To the impaired not enough of cloth that leads to the high temperature when cutting bed cut-off knife cuts in a large number, there has been the relevant technical scheme to disclose among the prior art, like patent application number: 2016112255778, filing date: in 2016, 12 months and 27 days, the invention and creation names are: the utility model provides a cutter cooling device of cutter, this application case is around setting up blast apparatus on the guide support pole, blast apparatus includes an annular blowing pipe and surrounds a section of thick bamboo that gathers wind in the blowing pipe outside, and the annular blowing pipe passes through the mount to be fixed on the guide support pole, and one side that the annular blowing pipe is close to gathering the wind section of thick bamboo is opened has a plurality of blowholes, can realize continuous cooling, use safe and reliable, but the device cooling efficiency is not high, is more applicable to and tailors low melting point material. Again as in patent application No.: 2014103070152, filing date: 6, month and 30 days 2014, the name of the invention and creation is as follows: a cutter cooling mechanism for the cutting bed; in this cut-off knife cooling body for cutting bed, cooling gas gets into inlet port, ring channel in proper order through the air inlet on the pressure disk to directly blow the cold gas cooling to the cut-off knife of establishing in the through-hole in wearing, in order to reach the effect of cooling off the cut-off knife, this mechanism cooling accuracy is high and cooling efficiency is high, cooling gas circulates in this cooling body's inside in addition, so cooling gas's loss volume is very few, in order to reduce the waste of resource, reduces the cooling cost.
It is therefore obvious that above-mentioned cutting bed cut-off knife all is that cooling body through outside independent setting carries out cooling to the cut-off knife, and the cooling body structure of this kind of outside independent setting is complicated, still causes the cutter high temperature easily when cutting in a large number, and the influence cuts the effect, and outside cooling body adopts forced air cooling mode cooling cut-off knife in addition, and the cold air meets the high temperature cut-off knife and can produce steam pollution cloth, and direct water spray cooling also can lead to the cloth to pollute equally.
To the above-mentioned outside cooling body pollutes the not enough of cut-off knife easily, prior art also relevant technical scheme discloses, patent application no: 2016105144836, filing date: in 2016, 7, 2 days, the invention and creation name is: a cutting knife with a cooling coating; the proposal discloses a cut-off knife with a cooling coating, the cut-off knife is used for cutting the low melting point cloth, and the surface of the cut-off knife is coated with a magnesium oxide or aluminum oxide coating; in addition, a plurality of radiating fins which are annularly arranged in a multi-ring mode are arranged on the surface of the cut-off knife, magnesium oxide or aluminum oxide coatings are coated on the surfaces of the radiating fins, the cut-off knife with the cooling coatings is relatively simple in structure and convenient to cool, and the cut-off knife can be continuously cooled.
