Abstract
The utility model relates to a device for leading threads from the axis of a lower shuffle of a sewing machine, which comprises a hollow rotating shaft, a hollow eccentric shaft, bearings, an internal shuttle, a hollow rod of the internal shuttle, a hollow hose, a fastening sleeve, a filling opening, an oil sink, a thread hole and a shuttle shell, wherein the two end ports of the hollow rotating shaft are provided with bearings, the hollow eccentric shaft extends into the hollow rod of the internal shuttle through the bearings, the other end of the hollow eccentric shaft is sleeved with the hollow hose, and the fastening sleeve is arranged at the sleeving position of the hollow eccentric shaft and the hollow hose. The utility model has simple structure and ingenious concept, directly leads threads outwards through the hollow axis of the lower shuttle to replace the thread supply of a shuttle cylinder of the shuttle shell, removes the trouble that a sewer frequently changes the shuttle cylinder used as a thread ring, is suitable for continuous sewing operation and greatly improves the working efficiency.
Description
Technical field
The utility model relates to shuttle thread guide devices under a kind of sewing locomotive, say so more specifically by following shuttle turning cylinder the axle center from the outside directly lead-in wire replace in the bobbin case shuttle tube for the device of line.
Background technology
Along with the development of needle trade is rapid, the kind of sewing locomotive is also more and more, and the sewing locomotive that is generally used for making operation has flat-bed machine, flush joint double needle machine, bar tacking machine, lockstitch button holder etc., also has all kinds of bottom lines with the degree type locomotive of shuttle tubes for lines.Because the shuttle cylindrical shell in the bobbin case is long-pending little, the coil quantity that is twined seldom when making operation continuously, frequent shuttle changing tube to make coil, troublesome poeration, and production efficiency is low, forgets thread-changing sometimes, also causes turning over the worker.So the shuttle tube is not suitable for the work of making continuously for line.
The utility model content
The purpose of this utility model provides shuttle axial lead device under a kind of sewing locomotive, directly goes between from the outside by the axle center of descending the shuttle turning cylinder, has solved existing shuttle tube and has supplied line to making the problem that operation brings inconvenience continuously.
The technical solution of the utility model is achieved in that under a kind of sewing locomotive shuttle axial lead device, and it comprises: hollow turning cylinder, hollow concentric shafts, bearing, interior shuttle, interior shuttle hollow stick, hollow tube, adapter sleeve, charging hole, oil groove, line hole, bobbin case are formed, it is characterized in that: hollow turning cylinder two-port is provided with bearing, the hollow concentric shafts extends in the interior shuttle hollow stick by bearing, hollow concentric shafts other end headgear has hollow tube, and the socket place of hollow concentric shafts and hollow tube is provided with adapter sleeve.
Feature of the present utility model also is:
The wall of above-described hollow turning cylinder is provided with charging hole, and the socket place of hollow turning cylinder and bearing is provided with oil groove.
Shuttle hollow stick wall is provided with the line hole in above-described.
Above-described bobbin case is no internal core sleeve bobbin case.
Utility model efficient
Shuttle axial lead device under a kind of sewing locomotive of the present utility model, it is simple in structure, is skillfully constructed.By following shuttle quill shaft mind-set outside directly lead-in wire replace in the bobbin case shuttle tube for line, reduced the trouble that the frequent shuttle changing tube of sewing making work is made coil, suitablely make work continuously, improved operating efficiency greatly.
Description of drawings
Now with specific embodiment the utility model is further specified in conjunction with the accompanying drawings
Accompanying drawing is the utility model sectional structure schematic diagram
Among the figure: hollow turning cylinder 1, hollow concentric shafts 2, bearing 3, interior shuttle 4, interior shuttle hollow stick 5, hollow tube 6, adapter sleeve 7, charging hole 8, oil groove 9, line hole 10, bobbin case 11, outer shuttle 12, sewing thread 13.
The specific embodiment
Referring to accompanying drawing as can be seen, under a kind of sewing locomotive of the present utility model shuttle axial lead device be by hollow rotate shuttle axle 1, hollow concentric shafts 2, bearing 3, interior shuttle 4, interior shuttle hollow stick 5, hollow tube 6,, adapter sleeve 7, charging hole 8, oil groove 9, line hole 10, bobbin case 11, outer shuttle 12, sewing thread 13 are formed, hollow turning cylinder 1 two-port is provided with bearing 3, and bearing 3 has played hollow turning cylinder 1 and hollow concentric shafts 2 does not produce rubbing action; In the shuttle hollow stick 5, hollow concentric shafts 2 other end headgears had hollow tube 6 in hollow concentric shafts 2 extended to by bearing 3, and their threes of hollow concentric shafts 2, interior shuttle hollow stick 5, hollow tube 6 become socket arranged in a straight line, become the axial lead direct channel; The socket place of hollow concentric shafts 2 and hollow tube 6 is provided with adapter sleeve 7, and the adapter sleeve 7 has here not only played centres axle 2 and hollow tube 6 effect of being connected firmly, and has particularly risen to fix hollow concentric shafts 2 and can not rotate, and impels the sewing thread 13 can the winding effect; Wherein, hollow turning cylinder 1 wall is provided with charging hole 8, the cover of hollow turning cylinder 1 and bearing 3 injects lubricating oil and flows in the bearing 3 by oil groove 9 by hollow turning cylinder 1 inboard again by locating to be provided with oil groove 9 in charging hole 8, reach the maintenance effect of reducing friction and preventing to get rusty; Interior shuttle hollow stick 5 walls are provided with line hole 10; Because the front end of interior shuttle hollow stick 5 is solid, only between interior shuttle hollow stick 5 hollow and solid, establishes line hole 10 and could guide to the line in the hollow concentric shafts 2 in the bobbin case 11; Bobbin case 11 is no internal core sleeve bobbin cases.Because be provided with heart cover in the original bobbin case 11, interior shuttle hollow stick 5 is enclosed within the heart cover, and line hole 10 is just covered in by heart cover, so with no internal core sleeve bobbin case.
As long as sewing thread 13 is introduced from the port of hollow tube 6, by hollow concentric shafts 2, in the shuttle hollow stick 5, logical again cable-through hole 10 causes in the bobbin case 11, draws by interior shuttle 4, outer shuttle 12 in bobbin case 11 with conventional method at last in guiding to again in use.
