Abstract
The invention relates to a surface thread clamping mechanism used on an embroidery machine, comprising a handpiece and a needle bar rack. An electromagnet base is positioned on one side of the handpiece and an electromagnet is positioned on the electromagnet base. A synchronous axle is also positioned on the electromagnet base. One end of the synchronous axle is fixedly connected with a lever plate and the other end is connected with an adjustable lever plate, which is fit-connected with one end of the electromagnet mandrel. A grip slipper is fixed arranged on the needle bar rack, a through hole is positioned on the grip slipper corresponding to the needle position, and a clamping axle and a spring are positioned inside the through hole. The lever plate and one end of the clamping axle are in fit connection. The other end of the clamping axle is fixedly connected with a clamping plate; under the normal state, the grip slipper and the spring are used to press the surface thread on the grip slipper. The surface thread clamping mechanism has the advantages that when the electromagnet is cut off with the power, the surface thread will be clamped by the clamping plate and then the surface thread is controlled to avoid errors. When the embroidery is carried out, only the handpiece embroidery needle clamping plate is open to permit the corresponding surface thread to feed the thread with the movement of the picking thread bar and the other surface threads are clamped by the clamping piece.
Description
Technical field
The present invention relates to the embroidery machine field, especially a kind of upper thread clamping device that on embroidery machine, uses.
Background technology
When embroidery machine was done at embroidery, because colour changing and shutdown etc., upper thread was under factors such as tension force and natural wind, and upper thread comes off, and broke away from pin hole or twined disorderly, caused embroidery worker troublesome poeration, and disadvantage such as generation trimming length disunity.Present embroidery machine, upper thread is controlled less than effective when shutdown and trimming.Deal with problems, must control upper thread.
Summary of the invention
The present invention will solve the shortcoming of above-mentioned prior art, and a kind of upper thread clamping device that uses on embroidery machine is provided.
The present invention solves the technical scheme that its technical problem adopts: this upper thread clamping device that uses on embroidery machine, comprise head and needle bar frame, side at head is equipped with electromagnet base, electromagnet is housed on the electromagnet base, synchronizing shaft also is housed on the electromagnet base, one end of synchronizing shaft is fixedly connected with lever plate, and the other end of synchronizing shaft is connected with the adjustable lever plate, and adjustable lever plate and electromagnet mandrel one end are and are connected; Be fixed with grip slipper on the needle bar frame, grip slipper is provided with the through hole of relative pin position, and clamp axis and spring are housed in this through hole, and an end of lever plate and clamp axis is and is connected, and the other end of clamp axis is fixedly connected with grip block; Grip block under normal conditions, grip slipper and spring make upper thread are pressed on the grip slipper.
The adjustable lever plate is provided with the screw of the relative position that is used to lock adjustable lever plate and synchronizing shaft among the present invention.
The next door of adjustable lever plate is provided with and is used to make the identical all the time torsion spring together of adjustable lever plate and electromagnet mandrel one end among the present invention.
Grip block is a trench structure among the present invention, and an end of grooved is for ease of the triangular form of unwrapping wire, and there was the notch of line the centre, had the handle of carrying plate.
The effect that the present invention is useful is:
1, electromagnet outage, upper thread promptly is held plate holder and holds, and upper thread is controlled, avoids disadvantage.
2, embroider when doing, have only the head embroidery of embroidering work to make pin position grip block and open, allow corresponding upper thread with thread take-up tension lever motion line sending, other upper thread then is held sheet and clamps, and disadvantage does not take place.
3, during trimming, upper thread is held plate holder and holds, length, uniform tension in order, and trimming length uniformity is fine.Stability might as well.
4, during withdrawal of needle, first pin is not because the shank drive block puts in place, and pin does not fall, and upper thread does not come off.
5, this mechanism directly is fixed on aluminium alloy head right side with two screws, and is fixing reliable, stable, simple.
6, the electromagnet of this mechanism installation is sensitive reliable.

The specific embodiment
The invention will be further described below in conjunction with drawings and Examples:
As shown in the figure, this upper thread clamping device that on embroidery machine, uses, comprise head 15 and needle bar frame 14, on the right side of head 15 electromagnet base 1 is installed, electromagnet 2 is housed on the electromagnet base 1, synchronizing shaft 3 also is housed on the electromagnet base 1, an end of synchronizing shaft 3 is fixedly connected with lever plate 4, the other end of synchronizing shaft 3 is connected with adjustable lever plate 7, and adjustable lever plate 7 is with electromagnet mandrel 2 one ends and is connected; Adjustable lever plate 7 is provided with the screw 11 that is used to lock adjustable lever plate 7 and the relative position of synchronizing shaft 3, and when adjustable lever plate 7 was adjusted to required angle, locking had promptly locked the relative position of adjustable lever plate 7 with synchronizing shaft 3.The next door of adjustable lever plate 7 is provided with and is used to make the identical all the time torsion spring 5 together of adjustable lever plate 7 and electromagnet mandrel 2 one ends.Be fixed with grip slipper 10 on the needle bar frame 14, grip slipper 10 is provided with the through hole of relative pin position, clamp axis 13 and spring 12 are housed in this through hole, one end of lever plate 4 and clamp axis 13 is and is connected, the other end of clamp axis 13 is fixedly connected with grip block 9, and grip block 9 is a trench structure, and an end of grooved is for ease of the triangular form of unwrapping wire, there was the notch of line the centre, had the handle of carrying plate.Grip block 9 under normal conditions, grip slipper 10 and spring 12 make upper thread are pressed on the grip slipper 10.
Operation principle: the present invention is to be power source with the electromagnet, under computer control, by the effect of an interlock lever plate and grip block, has realized that the chain of command wire clamp holds mechanism.Send the signal controlling electromagnet by computer and make the electromagnet closure, when electromagnet 2 closures, electromagnet mandrel moving linearly, thus promote 7 deflections of adjustable lever plate, the deflection of adjustable lever plate 7 makes the 4 synchronous deflections of truck dead lever plate, and clamp axis 13 is pushed up in the deflection of truck dead lever plate 4; When clamp axis was pushed, grip block promptly lifted, and grip block 9 leaves 2～3mm distance with grip slipper 10, and upper thread gets final product work.When shutdown, broken string, trimming, when the electromagnet dead electricity, this process is reverse, because the effect of torsion spring is promptly depressed, has so just formed the opposite wire clamp and has held process, guarantees upper thread relative size unanimity.
In addition to the implementation, the present invention can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of requirement of the present invention.
