Description
Technical field
The utility model relates to a kind of integral cosine doffing device of ring throstle, especially relates to the improvement of holding yarn mechanism in the automatic integral cosine doffing device.
Background technology
Doffing operation behind traditional ring throstle resultant yarn full packages is by artificial winding and finish by only having dialled yarn, and not only labour intensity is big, recruitment is many for this mode of doffing, and fine spining machine downtime is long, running efficiency is low.For this reason, people design the ring throstle with automatic integral cosine doffing device, the disposable doffing operation of finishing whole fine spining machine simultaneously of its energy, thus greatly reduce labour intensity, improved production efficiency.
Existing integral cosine doffing device to hold yarn mechanism all be from the winding top clamping of yarn and grasp into yarn bobbin.China's utility model patent (patent No.: 94238649.3) disclose a kind of " holding mechanism of fine spining machine integral cosine doffing device ", this holding mechanism is that the gripping counterbore wall at back-off circumferentially is evenly equipped with three clamp boss, wherein two clamp boss are to be arranged at the fixing lug boss that grips on the counterbore hole wall, and another clamp boss is can be at the grip slide of radial expansion slip, and this grip slide is controlled it by a rubber cup that can charge and discharge gas and gripped radially sliding of hole.Grip the counterbore back-off when doffing in the end of the winding bobbin of yarn, rubber cup drives grip slide and makes it to clamp with other two fixing lug boss the head of the winding bobbin of yarn, to finish the doffing operation of fine spining machine.
The yarn mechanism of holding of this structure still exists many deficiencies in actual use: bikini clamp structure at first, winding shaping and single thread quality in order not influence resultant yarn on the winding bobbin of yarn in use, bite can only contact with the bobbin end surface, and can not contact with resultant yarn, this just must occupy the bobbin tip position, reduced the resultant yarn capacity around yarn space and bobbin of bobbin, and the minimizing of resultant yarn capacity causes the cycle of doffing to shorten, the increased frequency of doffing.The 2nd and since in three bites two fixing, one be slide block slidably, the center line of three formed Clamping Centers of bite and bobbin and fine spining machine spindle certainly exists off-centre during clamping, this off-centre can cause the deflection repeatedly of spindle, bobbin again during clamping, very easily cause the crooked even fracture of spindle, bobbin, directly influence the smoothness of operation and the service life of bobbin.The 3rd, this point type clamp structure, the clamping contact area is little, often causes clamping frictional force deficiency and appearance extracting slippage, and the general equal less than 96% of tube pulling snatch rate in actual the use after automatic collective doffs, must manually participate in.Therefore, not only the bobbin snatch rate is not high in the yarn mechanism of holding of existing fine spining machine integral cosine doffing device, and spindle, bobbin is had obvious impairment when grasping.
The utility model content
In order to overcome the above-mentioned deficiency of existing in prior technology, it is high and to the yarn holder of spindle, the undamaged fine spining machine integral cosine doffing device of bobbin that technical problem to be solved in the utility model provides a kind of bobbin snatch rate.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: the yarn holder of this fine spining machine integral cosine doffing device, comprise the yarn holder body, described yarn holder body is a cylindrical body that connects, and on the internal face of yarn holder body perforation cylindrical body the yarn holder air bag is housed; The outer tube wall of yarn holder body is provided with yarn holder support arm and compressed air piping, and this compressed air piping is communicated between yarn holder body and the yarn holder air bag.
A kind of preferred implementation of the present utility model is: retaining ring is turned up in the port position of the perforation cylindrical body of yarn holder body in described yarn holder air bag end, and is sealingly fastened on the yarn holder body by annular sealing cover.
Another preferred implementation of the present utility model is: the inner tube wall of described yarn holder body is provided with the ring rib of interruption, and this ring rib height is 0.2～1.2mm.
After adopting said structure, because the yarn holder body is to connect on tubular structure and its inner core wall yarn holder air bag is housed, feed compressed air when doffing and the yarn holder air bag of bulging can from the full packages yarn winding around the fill the span of a man's arms resultant yarn surface of cop winding with allocation resultant yarn yarn, yarn holder air bag and resultant yarn surface contact area is big so on the one hand, cohesive force is strong, avoided grasping the generation of slip phenomenon, snatch rate improves greatly, and the actual yarn holder of this structure of proof that uses reaches 100% to the winding extracting efficient of yarn.The yarn holder air bag is filled the span of a man's arms on the winding surface of yarn on the other hand, rather than is held on the bobbin apical position, can increase the resultant yarn capacity of bobbin so to greatest extent, improves the actual production efficient of fine spining machine.More main is the holder air bag is from yarn winding around the obvolvent yarn winding, has the automatic aligning effect, can guarantee the consistent of Clamping Center and spindle, bobbin center line, can not produce deflection, flecition to spindle, bobbin, avoided the damage of holder effectively, thereby improved the smoothness of operation and the service life of spindle, bobbin spindle, bobbin.This yarn holder also has simple in structurely simultaneously, is convenient to the advantage of installing and using.
Description of drawings
Be described in further detail below in conjunction with the yarn holder of the drawings and specific embodiments the utility model fine spining machine integral cosine doffing device.
