Description
Technical field
The present invention relates to embroidery equipments, and in particular to a kind of small semiautomatic cross embroidery embroidery machine.
Background technique
Cross embroidery is commonly called as civil as " cross-stitch work " or " choosing benefit to embroider ".Early in 4th century of Christian era, cross embroidery just from Turkey via
Italy spreads in Europe.Cross embroidery is a kind of ancient national embroidery, is had a long history.Nowadays cross embroidery is come
China is applied and is developed in China.People are pressing the gimmick of traditional handicraft, in addition the skill of some modern high technologies
Art makes its oneself warp become a rising industry.This industry of cross embroidery is bound to become competitive in China, there is length
The complete industrial chain of remote prospect.
Although current cross embroidery propagated in countries in the world it is so extensive, it is traditional hand-made for being replaced using machine
Technique enables the research of cross embroidery industrial mass production, in countries in the world still without feasible program.Although cross embroidery is in public affairs
Member was just passed to China in 4th century, had had a long history in China.But China for how using mechanical industry production side
Formula goes the research for replacing traditional-handwork cross embroidery, is inchoate from the 1990s.
In the international market, state-of-the-art technology is computerized emboridering machine at present.This computerized emboridering machine its be substantially exactly
One has the sewing machine of servo feed system, and does not have cross embroidery function.So the research of cross embroidering machine is still generation
The problem of criticality.
Although cross embroidery is just being passed to China, and this ancient national embroidery in 4th century of Christian era, have in China
Long history.But theoretically, China is for going to replace traditional-handwork cross embroidery how in the way of mechanical industry production
Research, be inchoate from the 1980s.
Today, in China, textile industry degree is very high, and China's morning, oneself became textile exports big country.But for cross
Embroidering pattern product, how industrialized mass production is still without practicable solution.Although some websites on present network
Call oneself and cross embroidery embroidery machine is provided, but be not cross embroidering machine truly, and only has the sewing of embroidering function
Machine.
Present existing some computerized emboridering machines, are not exclusively passed through cloth using embroidered needle, are drawn by the way of buried end line
Fasten embroider line；It can be only done the techniques such as embroidery, do not have cross embroidery function, and embroidered needle structure is single-head needle, and cross embroidery needs
Embroidered needle is wanted to pass through cloth completely；It needs to tense embroider line by type throwing mechanism, does not have to buried end line, embroidered needle structure is double-ended needle.
Cross embroidering machine and computerized emboridering machine function comparative analysis are known by front, although the function of computerized emboridering machine is strong
Greatly, but computerized emboridering machine its substantially, be exactly one have servo-system sewing machine.And current this kind of machine, do not have
The function of standby production cross embroidery technique.
So the research of cross embroidering machine is still global problem, and have broad prospects in the future.
