Description
Technical field
The present invention relates to a kind of sewing embroidery head of spininess post.
Technical background
At present, the sewing embroidery of bull polychrome is more and more used, and one of appointed condition of bull polychrome sewing embroidery to be requirement provide and the sewing embroidery head of the spininess rod structure of quantity pin post such as required sewing embroidery yarn form and aspect.The embroidery of the sewing of spininess rod structure now head roughly is divided into two types: a class is circular spininess rod structure head, another kind of is rectangle spininess rod structure head, the common ground of two class spininess rod structure heads is: each head has only a fixing pin post to drive the operation station, drive operation station embroidering work to change the embroidery color though can change the pin post that has different colo(u)r streaks in the pin post via the revolution of pin post dish or translation, but that pin post that only is positioned at pin post driving operation station just can be driven embroidering work, say exactly, present spininess post sewing embroidery head all is single station work pattern that drives, and is called for short single station work pattern.
Because the rise of the demand of the little pattern embroidery of view picture trade mark and design of scattered small flowers and plants in recent years, existing market also is applied to such embroidering work with multi-end multi-needle post embroidery machine more, and the characteristics of this class operation are little pattern, few color, arrange compactness in order.Multi-end multi-needle post sewing embroidery machine job analysis with present single station though many pin posts are arranged on each head, only has a pin post to devote oneself to work at every turn, obviously is a kind of poor efficiency output and the wasting of resources.
In addition, no matter be circle or rectangle spininess post sewing embroidery head, existing structure also exists the following relevant increase pin post configuration and the problem of precision decay respectively.
Circular spininess rod structure head is representative with Japanese Barudan product; This class head is made up of headstock, the pin post dish with many pin posts, the thread take-up tension lever dish with many thread take-up tension levers and thread take-up lever link, pin post driving mechanism, thread take-up tension lever driving mechanism, bottom line mechanism substantially.
The precision retention time is longer than rectangle spininess rod structure head to circular spininess rod structure head because it is embroidered, so liked by market, but since its structure and configuration mode limit can only be along in the segmental arc of about 1/3 arc length on the pin post distribution circle of its round pin post dish the pin post being set.With the said firm's BENSH-YN-S/BS series of products and up-to-date EDSH-YN-BS series of products a little earlier is example, it is about 40mm at pin post dish upper edge radius, central angle is about and intensively on the pin post distribution segmental arcs of 110 degree is provided with 9 pin posts, but this also can only satisfy the needs of 9 looks embroidery, if increase the embroidery color, just need on head, to increase again pin post quantity, so just must realize by the pin post distribution circle diameter that adds large needle post dish, owing to only have 1/3 can be used for acquiring the pin post in the pin post distribution circle arc length that the pin post dish after strengthening increases newly, and because the head spacing, cantilever carrying and other factors are limit, thereby significantly increase pin post quantity and reach that significantly to increase the color of embroidering be infeasible to increase pin post dish diameter.So present circular spininess rod structure head mostly is 9 pin posts most, promptly can only satisfies the needs of 9 looks embroidery, and when more embroidery yarn look is required, can only helplessly turn to the rectangle spininess post head scheme that adopts.
Rectangle spininess rod structure head is representative with Japanese Tajima, Barudan, German ZSK and a China north day bird product; But rectangle spininess rod structure head is to adopt a driving head to drive a single station work pattern that carries out embroidering work in many pin posts on the rectangle head of translation by turns equally, has the low problem of work efficiency equally; And also there is atypical awkward situation at increase pin post in rectangle spininess rod structure head aspect increase embroidery color, rectangle spininess rod structure head is generally 9 pin posts at present, reach most 15 pin posts, though rectangle spininess rod structure head can increase pin post quantity by increasing head length, but because its occupy-place along its length is greater than the chord length of camber line, so the horizontal occupy-place of two kinds of heads contrast rectangle spininess rod structure heads of same pin post distance and pin post quantity is more; Severe is because the vibration that the form of the cantilever force that rectangle spininess rod structure head produces behind translation conversion work pin post produces in equipment runs up is that dynamic loading will be at the head of head, reach maximum during the work of tailpin post, this dynamic load will cause the head precision to decay fast and cause the fatigue damage of head parts, rectangle spininess rod structure head script precision decays faster, and the origin cause of formation promptly comes from this, and the pin post quantity that significantly increases head must strengthen cantilever amount and dynamic loading, so more aggravated precision decay and parts damages, faced puzzlement too to increase embroidery color aspect so rectangle spininess rod structure head increases the pin post when keeping and improving mechanical precision.
In sum, the sewing of above-mentioned two types spininess rod structure embroidery head, the sort of at present operating efficiency that all exists is low, and is difficult to satisfy market to the more requirement of thorniness embroidery color.Can seek a new technical scheme, this scheme can satisfy when the little pattern view picture embroidery of simple pattern and significantly promotes work efficiency, can satisfy more thorniness simultaneously again and embroider the arts demand of color and the mechanical precision of keeping head more long-term effectively, and above-mentioned demand makes the improvement innovation of spininess post handpiece structure become the technological development direction of multi-end multi-needle sewing embroidery class machinery.
