Abstract
The utility model discloses a numerical control take-up-lever embroidering machine head which comprises a needle bar frame provided with a take-up-lever, and a machine head seat provided with a fan-shaped tooth transmission bar which is matched with the take-up-lever. A servo motor is arranged in the machine head seat and connected with the fan-shaped tooth transmission bar through a servo motor transmission shaft. The numerical control take-up-lever embroidering machine head has the advantages that mechanical transmission is changed into numerical control transmission so that service life of equipment is prolonged, the bottleneck of high-speed embroidery technology is broken through, and mechanical friction noise is lowered; withdrawing and releasing parameters of the take-up-lever can be changed and adjusted quickly by means of changing a computer control program, and therefore rapidness and convenience are brought to embroidery equipment researchers, and the troubles of repeating manufacture and changing cam curves in a traditional cam structure research are avoided; and meanwhile the cam curves are difficult to display relatively complicated motion parameters due to restriction of features of the cam curves, while a numerical control take-up-lever structure is not restricted and can achieve any complicated motion parameters so as to add a novel approach for research and development of a high-speed and low-noise embroidery machine.
Description
Technical field
The utility model relates to a kind of embroidering machine head, and more specifically, it relates to a kind of numerical control thread take-up tension lever embroidering machine head.
Background technology
In the computer embroidery handpiece structure of prior art, curve controlled cam drive bar and the sector drive link of the nylon cam that is driven by head spindle are made circular motion, realize that thread take-up tension lever is to embroidering the folding and unfolding control of line.Because cam drive bar and nylon cam curved surface rely on frictional drive, in long-term high-speed motion, very easily cause the cam wear distortion, thread take-up tension lever can not be put in place to the control of embroidering line, and outage increases or the embroidery quality accident when causing embroidery, has a strong impact on service life of equipment.In the manufacturing of high speed embroidery machine, the cam thread take-up tension lever has become technical bottleneck.
Summary of the invention
The purpose of this utility model is to overcome deficiency of the prior art, provides a kind of life-span long, and stability is high, the convenient numerical control thread take-up tension lever embroidering machine head of adjusting.
This numerical control thread take-up tension lever embroidering machine head, comprise the needle bar frame that is provided with thread take-up tension lever, the headstock that is provided with the sector drive link that cooperates with thread take-up tension lever, be provided with servomotor in the described headstock, described servomotor is connected to the sector drive link by the servo motor transmission axle.
As preferably: described needle bar frame is provided with the B axle, and thread take-up tension lever is located on the B axle.
The beneficial effects of the utility model are: 1, machine driving is changed into the numerical control transmission, improved service life of equipment, break through high speed embroidery technique bottleneck, reduce the mechanical friction noise.2, the change computer program can be changed fast and adjust thread take-up tension lever folding and unfolding parameter, and this brings quick and convenient to embroidery equipment research personnel, break the trouble that need repeatedly make and change cam curve in conventional cam structural research.Simultaneously, cam curve is subjected to itself characteristic limitations, is difficult to show complicated kinematic parameter, and the numerical control thread take-up lever structure is then unrestricted, can realize complicated arbitrarily kinematic parameter, for high-speed, the low noise of researching and developing embroidery machine increased new way.
Description of drawings
Fig. 1 is the utility model top view;
Fig. 2 is the utility model A-A cutaway view;
Fig. 3 is the utility model stereogram;
Reference numeral: servomotor 1, servo motor transmission axle 2, needle bar frame 3, headstock 4, thread take-up tension lever 5, sector drive link 6, B axle 7.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described further.Although the utility model is described in connection with preferred embodiment, should know, do not represent that the utility model is limited among the described embodiment.On the contrary, the utility model will be contained alternative, modified and the equivalent in the scope of the present utility model that can be included in attached claims restriction.
Extremely shown in Figure 3 referring to Fig. 1, numerical control thread take-up tension lever embroidering machine head, comprise the needle bar frame 3 that is provided with thread take-up tension lever 5, the headstock 4 that is provided with the sector drive link 6 that cooperates with thread take-up tension lever 5, be provided with servomotor 1 in the described headstock 4, described servomotor 1 is connected to sector drive link 6 by servo motor transmission axle 2.Described needle bar frame 3 is provided with B axle 7, and thread take-up tension lever 5 is located on the B axle 7.
On traditional thread take-up tension lever drive mechanism, cancellation nylon cam and cam drive bar, change A axle is servo motor transmission axle 2 and at axle head servomotor 1 is installed that sector drive link 6 directly press the computer program driving by servomotor 1, finishes the retractable cable function of thread take-up tension lever 5 by gear drive.
