Description

A kind of automatic control foot device of electronic pattern sewing machine

Technical field:

The utility model belongs to sewing machine technique, particularly designs a kind of device that can control the presser feet height on the electronic pattern sewing machine when clock automatically that is used in.

Background technology:

Because the development of clothing industry, market to the demand of style on the clothes or pattern etc. more and more widely, so just require can be fast on clothes, to form the Sewing machines of style or pattern, more need us to accelerate improvement thus, to increase efficient to electronic pattern sewing machine.Electronic pattern sewing machine is the high-end machine in the Sewing machines, and it is to utilize the feeding structure of vertical, horizontal to drive the cloth-pressing device of machine, thereby drives the cloth motion, uses the stitching of Sewing machines to form principle again, reaches the purpose that forms all kinds of styles on cloth.At present, electronic pattern sewing machine when tailoring cloth, often run into by thin when expect to thick material or thick material cross to binder tension that the restriction owing to the presser feet height causes or the situation of cannot keeping under control cloth of approaching when expecting, thereby cause the in disorder of style or pattern, not attractive in appearance, so that the waste of artificial and dress material, the utility model is exactly to carry out the improved a kind of device that can control the presser feet height on the electronic pattern sewing machine when clock automatically that is used at this situation, it can make electronic pattern sewing machine when work freely by thin when expect to thick material or thick material cross to approach and expect, compress cloth simultaneously, make the style or the pattern of formation keep neat appearance, improve the efficient of work simultaneously.

The utility model content:

The purpose of this utility model is a kind of device that can control the presser feet height on the electronic pattern sewing machine when clock automatically that is used in of design.

The utility model comprises head 1, hinge drive unit 2, the spacing knob 3 of high point, the spacing knob 4 of low spot, knob holder 5, limit lever 6, axial screw 7, connecting rod A8, hinge screws 9, connecting rod B10, connecting rod C11, hinge axial screw 12, positioning linkage rod 13, rotation axial screw 14, connecting rod D15, connecting rod connecting plate 16, slide block 17, depression bar 18, presser feet 19, back-moving spring 20, split pin 21.It is characterized in that by programme-control hinge drive unit 2, when electronic pattern sewing machine by thin when expect to thick material or thick material cross to and approach when expecting, can be by programme-control hinge drive unit 2, and the height by its change presser feet 19 that moves up and down.Simultaneously, the height of presser feet 19 is restricted, specifically is to put the stroke of spacing knob 3 and the spacing knob 4 restriction limit lever 6 of low spot by the height that is installed on the knob holder 5, thereby controls presser feet 19.

The utility model embodiment 1, hinge drive unit 2 can be made of cylinder 22 and catch bar A23, when generally making, cylinder 22 is not worked, catch bar A23 keeps the home position, when the stitchbonded fabric of electronic pattern sewing machine by thin when expecting to thick material, cylinder 22 receives program command and starts working, catch bar A23 drivening rod A8 starts working, thereby drive the lifting of presser feet 19, when stitchbonded fabric is crossed when getting back to thin material by thick material again, perhaps stitchbonded fabric power cut-off when thick material, cylinder 22 drives catch bar A23 and replys original states.

The utility model embodiment 2, hinge drive unit 2 can be electromagnet 24, and catch bar B25 is fixed together with it, and its operation principle is identical with embodiment described in the utility model 1, and just this fact Example is by the electromagnet 24 final control presser feets 19 automatically of realizing.

The utility model also can be put the stroke that spacing knob 3, the spacing knob 4 of low spot and limit lever 6 are controlled presser feet 19 by height, adjusting by two knobs, presser feet 19 highly is controlled in the suitable height, so that style that forms or pattern keep neat appearance, improve the efficient of work indirectly.

Fig. 2 is the utility model embodiment 1 assembling stereogram;

Fig. 3 is the utility model embodiment 2 assembling stereograms;

Fig. 4 is the utility model position-limit mechanism installation diagram.

The specific embodiment:

With reference to Fig. 1, Fig. 2, the utility model embodiment 1 described hinge drive unit 2 can be made up of cylinder 20 and catch bar A21, when the stitchbonded fabric of electronic pattern sewing machine by thin when expecting to thick material, cylinder 20 receives program command and starts working, catch bar A21 drivening rod A8, begin to rotate around axial screw 7 thereby drive limit lever 6, at this moment, limit lever 6 is depressed hinge screws 9 downwards.Hinge axial screw 12 is installed on the connecting rod C11, simultaneously connecting rod C11 and positioning linkage rod 13 are linked together, rotating axial screw 14 is installed in positioning linkage rod 13 on the head 1, connecting rod B10 is connected with connecting rod C11 by screw, connecting rod D15 also is connected with connecting rod C11 by screw, and another section of connecting rod D15 is connected with connecting rod connecting plate 16 simultaneously, by screw slide block 17 is fixed on the connecting rod connecting plate 16 simultaneously, slide block 17 is held depression bar 18 tightly, 19 lower ends that are installed in depression bar 18 of presser feet.When limit lever 6 was depressed hinge axial screw 12 downwards, by above-mentioned linkage, connecting rod connecting plate 16 drove depression bar 18 with the slide block 17 that is fixed in the above, thereby drove the lifting of presser feet 19.Back-moving spring 20 tensions this moment, one end of back-moving spring 20 is to be fixed on the positioning linkage rod 13, the other end then hangs in the split pin 21 that is fastened on the head 1, when stitchbonded fabric is crossed when getting back to thin material by thick material again, perhaps stitchbonded fabric power cut-off when thick material, cylinder 22 drives catch bar A23 and replys original state, and back-moving spring 20 resets, and presser feet 19 is got back to initial position.

With reference to Fig. 3, the hinge drive unit 2 of the utility model embodiment 2 can be made of electromagnet 24 and catch bar B25, after program issues instructions to electromagnet 24, electromagnet 24 is started working, drive catch bar B25, drive then as linkage as described in the new embodiment 1, drive the motion of presser feet 19, realize the purpose of control presser feet automatically.

With reference to Fig. 4, be specifically related to position-limit mechanism, position-limit mechanism is put spacing knob 3, the spacing knob 4 of low spot, knob holder 5, limit lever 6, axial screw 7 by height and is formed, high spacing knob 3 of point and the spacing knob 4 of low spot are installed on the knob holder 5, knob holder 5 then is fixed on the head 1, axial screw 7 is contained in limit lever 6 on the head 1, and high simultaneously spacing knob 3 of point and the spacing knob 4 of low spot split the both sides at axial screw 7.When hinge drive unit 2 drive limit lever 6 move downward, the spacing knob 4 of the low spot on the left side begins to work, when limit lever 6 is rotated around axial screw 7, limit lever 6 left arms will be withstood by the spacing knob 4 of low spot behind certain altitude, limit lever 6 is no longer rotated, and presser feet 19 also just stops to descend.When hinge drive unit 2 drive limit lever 6 move upward, the height on the right is put spacing knob 3 and is begun to work, when limit lever 6 is rotated around axial screw 7, limit lever 6 right arms will be put spacing knob 3 by height behind the certain altitude and withstand, limit lever 6 is no longer rotated, and presser feet 19 also just stops to rise.
