As shown in fig. 1 and 2, the utility model provides a shuttle for circular weaving machine, including the shuttle 1, first tube socket 2 and second tube socket 3 rotate respectively and connect on the shuttle 1, be equipped with between the shuttle 1 and the first tube socket 2 and push first tube socket 2 to the compression spring 4 of second tube socket 3, the both ends of woof spindle 9 are fixed a position respectively on first tube socket 2 and second tube socket 3, be equipped with the elastic component 5 that elasticity supported woof spindle 9 on the shuttle 1, it has pendulum rod 6 to articulate on the shuttle 1, elastic component 5 and the linkage of pendulum rod 6, be equipped with brake block 7 on pendulum rod 6, elastic component 5 supports the spindle and makes brake block 7 support tight second tube socket 3. In fig. 2 the weft spindle 9 is shown replaced by a weft tube, the weft being not shown. The weft spindle 9 is arranged between the first tube seat 2 and the second tube seat 3, the elastic part 5 is deformed to drive the swing rod 6 to swing, the brake block 7 is further tightly abutted against the second tube seat 3 to increase the friction force, when the weft spindle 9 is replaced, the diameter is the largest, so that the deformation of the elastic part 5 is the largest, the pressure of the brake block 7 on the second tube seat 3 is the largest, the friction force with the second tube seat 3 is also the largest, therefore, the rotating inertia force caused by the large mass of the newly replaced weft spindle 9 can be well overcome, the tensioning effect of weft yarns is ensured, the weft spindle 9 can be uniformly unwound, the diameter can be gradually reduced along with the unwinding of the weft spindle 9, the mass can be gradually reduced, the rotating inertia force is also gradually reduced, meanwhile, the deformation of the elastic part 5 is gradually reduced, the pressure of the brake block 7 on the second tube seat 3 is also gradually reduced, the friction force is correspondingly reduced, so that the tensioning effect of weft yarns is kept in a balanced state, the weft yarn spindle 9 continues to be evenly unreeled, thereby improving the weaving quality.
As the function of the weft spindle 9 on the elastic part 5 and the interaction of the brake block 7 and the second tube holder 3 can be equivalent to two moments, as shown in figure 3, the distance from the contact position of the elastic part 5 and the weft spindle 9 to the rotation center of the swing rod 6 is L1, and the distance from the brake block 7 to the rotation center of the swing rod 6 is L2, in order to reduce the requirement on the elastic part 5 and weaken the adverse effect of the aging of the elastic part 5, the L2 is required to be less than or equal to L1, and the lever effect can be generated. In addition, the diameter of the weft spindle 9 can be gradually reduced in the unwinding process, the distance from the contact position of the weft spindle 9 to the rotation center of the swing rod 6 can be gradually increased, and the lever effect is equivalently gradually enhanced, so that the influence of elastic force reduction caused by gradual reduction of deformation of the elastic part 5 can be responded, the pressure reduction of the brake block 7 on the second tube seat 3 can be effectively avoided, and the tensioning effect of weft yarns is ensured.
In this embodiment, since the position of the second tube seat 3 relative to the shuttle body 1 does not change, only the shuttle body 1 rotates, so the brake block 7 is selected to tightly abut against the second tube seat 3 to increase the tension of unwinding the weft yarn. It will be appreciated that it is also possible to design the brake shoes 7 to abut against the first socket 2 for the purpose of the invention, and even to design two brake shoes 7 to abut against both the first socket 2 and the second socket 3 for the purpose of the invention.
