Description
Technical field
the utility model relates to a kind of supporting device of circular loom parallel spool, belongs to plastics package machinery field.
Background technology
Circular loom refers to the weaving machinery utilizing circuit orbit to carry out throwing in parallel in the warp opening friendship.Existing circular loom structure as shown in Figure 1, containing motor pulley 1, belt 2, big belt pulley 3, main shaft 4, cam 5, clip wheel 6, lever 7, comprehensive band deflector roll 8, comprehensive band 9, heald 10, nutted rod 11, shuttle body 12, spindle 13, circuit orbit 14, shuttle pushing wheel 15, organizine 16, determines longitude circle 17, braiding cylinder cloth 18.
Operation principle is as follows, power is reached main shaft 4 through motor pulley 1, belt 2, big belt pulley 3 by motor, again by the cam 5 be fixed on main shaft 4 by being fixed on clip wheel 6 activation lever 7 on lever 7 around fixing point reciprocally swinging, finally driven by lever 7 end and combine band 9, heald 10 pumps together.
Be through organizine 16 on heald 10 under the driving of comprehensive band 9, inside and outside layer completes to open ships dynamic, and the organizine 16 that nutted rod 11 can split friendship provides suitable tension force to open friendship with what ensure organizine 16.The spindle 13 that shuttle 12 is installed, circuit orbit 14 has been driven by the shuttle pushing wheel 15 be fixed on main shaft 4 motion of throwing in weft yarn.Determining longitude circle 17 is folding footpath size for fixing braiding cylinder cloth 18.
The support pattern of the weft yarn spindle 13 in shuttle 12 is such: spindle 13 is horizontal in shuttle body central authorities, front end is by comprising: shuttle body 23, front support axle 19, bearing 20, front tapered sleeve 21, compression spring 22, rear end comprises rear trunnion 24 and rear tapered sleeve 25, its forefront pressure spring 22 is enclosed within front support axle 19, front tapered sleeve 21 is arranged on bearing 20, bearing 20 is arranged on front support axle 19, front support axle 19 is arranged on shuttle body 23, compression spring 22 one end leans against on the inner ring end face of bearing 20, the other end leans against on shuttle body 23, bearing 20 can slide together with front tapered sleeve 21 on bolster 19, front tapered sleeve 21 can rotate on bearing 20, rear end is by rear trunnion 24, rear tapered sleeve 25 and bearing 20 form, rear tapered sleeve 25 is arranged on bearing 20, bearing 20 is arranged on rear trunnion 24, rear trunnion 24 is arranged on shuttle body 23, rear tapered sleeve 25 is axially irremovable, before, rear end bolster 19, 24 is coaxial.Spindle 13 is clamped on the taper seat of forward and backward tapered sleeve 21,25 by forward and backward tapered sleeve 21,25, compression spring 22 1 aspect is used for providing certain chucking power to ensure spindle 13 stability in the course of the work to spindle 13, and after allowing spindle 13 rear end leave when compressing again on the other hand, tapered sleeve 25 is beneficial to load and unload spindle 13.
Problem thereby produces: because parallel is at the surperficial unwrapping wire of spindle 13 in braiding process, because the canoe of spindle 13 is spiral helicine canoe.During unwrapping wire, the axial location of wire vent point, in continuous change, when unwrapping wire position is in the backhaul at spindle 13 two ends in addition, due to the change of unwrapping wire length physical dimension and the change of unwinding direction, and causes the tension value of parallel all can have a greater change.Although there is various governing mechanism of tension, also cannot eliminate completely, the changing value of weft tension finally can be made to produce double direction impulse power in the axis of spindle.The elastic force constraint of to be one end the be compression spring 22 of the axial constraint due to spindle, and the rear tapered sleeve 25 of opposite side is rigid constraint.Cause spindle 13 thus in the course of the work, because the elastic force of impulsive force and compression spring 22 interacts, and the chucking power of spindle 13 is changed, thus cause spindle 13 axially producing vibration, finally cause between spindle 13 end face and forward and backward tapered sleeve 21,25 conical surface and produce relative motion, cause wearing and tearing, make equipment failure.
