Abstract
The invention relates to a paying off roller which comprises an inner frame with a trapezoid section cutting plane. A vertically-through connection hole is formed in the center of the inner frame, symmetrical spring clamps are arranged on the inner wall of the connection hole, an outer frame is arranged outside the inner frame, the bottom of the outer frame is slightly higher than the bottom of the inner frame, the inner frame is movably connected with the outer frame through rolling balls, and a soft material layer is arranged on the outer side face of the outer frame. The paying off roller is simple in structure, the outer frame can be prevented from generating inertia through matching of the inner frame and the outer frame, and sewing threads can not be excessively paid off due to inertia.
Description
Technical field
The present invention relates to a kind of actinobacillus device, relate in particular to a kind of unwrapping wire roller.
Background technology
Sewing machine is to use one or more sewing thread, forms one or more stitchings on sewing, the machine that makes one or more layers sewing interweave or unite by a seam.Therefore sewing thread is one of materials indispensable on sewing machine.
Sewing thread is to be all generally wound on the roller of plastics or papery, during use, the roller that is wound with sewing thread is nested with on sewing machine roller shaft, because drum shaft diameter is smaller, to adapt to the roller of different pore size, therefore between roller and roller shaft, there is larger space, during sewing machine work, by sewing thread, drive roller to rotate on roller shaft, carry out unwrapping wire.
Because the Gap-Ratios between roller and roller shaft is larger, even so roller sewing thread in unwrapping wire process stop, but roller also can be transferred one section of line at inertia, easily causes the confusion of sewing thread.
Summary of the invention
Technical matters to be solved by this invention is that a kind of unwrapping wire roller that can prevent sewing thread confusion in unwrapping wire process is provided.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions: a kind of unwrapping wire roller, there is cutting plane and be trapezoidal internal frame, described internal frame center is provided with the connecting bore of up/down perforation, connecting bore inwall is provided with symmetrical Spring Card, the outer setting of described internal frame has outrigger, and the bottom of outrigger is a little more than the bottom of internal frame, and by ball, is flexibly connected between internal frame and outrigger.
Preferably, described outrigger lateral surface is provided with the soft bed of material.
Compared with prior art, usefulness of the present invention is: this unwrapping wire roll structure is simple, by the cooperation of internal frame and outrigger, can prevent that outrigger from producing inertia, and assurance sewing thread can not put because of inertia more.
accompanying drawing explanation:
Below in conjunction with accompanying drawing, the present invention is further described.
Fig. 1 is unwrapping wire roll structure cutaway view of the present invention.
In figure: 1, internal frame; 2, outrigger; 3, connecting bore; 4, ball; 5, Spring Card; 6, the soft bed of material.
the specific embodiment:
Below in conjunction with the drawings and the specific embodiments, describe the present invention:
A kind of unwrapping wire roller shown in Fig. 1, there is cutting plane and be trapezoidal internal frame 1, described internal frame 1 center is provided with the connecting bore 3 of up/down perforation, connecting bore 3 inwalls are provided with symmetrical Spring Card 4, the outer setting of described internal frame 1 has outrigger 2, and the bottom of outrigger 2 is a little more than the bottom of internal frame 1, and by ball 4, is flexibly connected between internal frame 1 and outrigger 2, outrigger 2 lateral surfaces are provided with the soft bed of material 6, and the sewing thread that can guarantee to be wound on outrigger 2 can not disconnect because of friction.
During use, unwrapping wire roller shell is put on the unwrapping wire roll shaft of sewing machine, the Spring Card 5 being arranged on internal frame 1 inwall blocks unwrapping wire roll shaft, make internal frame 1 fixing, when the sewing thread on outrigger 2 is torn, outrigger 1 is realized and being rotated by ball 4, carries out unwrapping wire, and under the effect of ball 4 and internal frame 1, outrigger 2 there will not be inertia, makes sewing thread not understand and put more.
This unwrapping wire roll structure is simple, by the cooperation of internal frame 1 and outrigger 2, can prevent that outrigger 2 from producing inertia, and assurance sewing thread can not put because of inertia more.
It is emphasized that: be only preferred embodiment of the present invention above, not the present invention is done to any pro forma restriction, any simple modification, equivalent variations and modification that every foundation technical spirit of the present invention is done above embodiment, all still belong in the scope of technical solution of the present invention.
