The utility model discloses a hosiery machine inlet wire shuttle mechanism's theory of operation as follows:

the yarn has certain gravity in itself, and can pass through the threading holes 15 on the first threading plate 12 and the second threading plate 13 respectively. Because the incoming line shuttle mechanism is vertically arranged, the shuttle 7 is positioned at the lowest side of the incoming line shuttle mechanism, the yarns are easily sent to the incoming line hole 71, the winding among the yarns is reduced, the yarn feeding is easier, and the reliability of the yarn feeding is improved. The air cylinder on the shuttle releasing air cylinder assembly 1 is controlled by a computer control system, and the shuttle guide plate 6 is pushed to move downwards under the action of compressed air. The positioning pin 8 passes through the mounting groove 61, and the shuttle guide plate 6 moves through the mounting groove 61 under the action of the positioning pin 8. The projection 62 presses the curved slot 72 downwards, so that the shuttle 7 is thrown downwards and the yarn connected to the corresponding thread inlet 71 is thrown. At the moment, the tension spring 14 is stretched, when the computer system stops supplying air to the air cylinder, the shuttle 7 is driven to reset under the action of the elastic force of the tension spring 14, and the operation is repeated in a circulating way.

In order to meet different weaving requirements, the height of the position of the shuttle 7 is generally required to be controlled. The shuttle adjustment block 5 can rotate about the positioning pin 8 passing through the connection hole 51. When the distance that the adjusting screw 92 extends out of the first screw hole 91 is short, the first screw hole 91 can press the second positioning surface 53, the shuttle adjusting block 5 rotates, and the first positioning surface 52 swings towards the right side, and in the process that the shuttle guide plate 6 moves downwards, the connecting table 63 can not move continuously when contacting the first positioning surface 52, and the shooting position of the shuttle 7 becomes low. When the distance that the adjusting screw 92 extends out of the first screw hole 91 becomes longer, the first screw hole 91 can press the second positioning surface 53 to the limit position, the shuttle adjusting block 5 rotates, the swinging distance of the first positioning surface 52 towards the right side is increased, and in the process that the shuttle guide plate 6 moves downwards, the connecting table 63 contacts the first positioning surface 52 too early, so that the shuttle 7 cannot move downwards continuously, and the shooting position of the shuttle 7 is lower. The shuttle adjustment block 5, and thus the shuttle 7, can be controlled down to the proper position by adjusting the distance the screw 92 extends out of the first screw hole 91.

Shuttle 7, shuttle deflector 6, the cooperation of shuttle regulating block 5 one-to-one set up to a set of, and shuttle inlet wire mechanism can include the multiunit, shuttle inlet wire mechanism also can set up a plurality ofly, the vertical installation of hosiery machine around. In the application, one shuttle incoming line structure comprises five groups of shuttles 7, a shuttle guide plate 6 and a shuttle adjusting block 5, and the shuttle incoming line structure comprises four shuttles. Twenty shuttles 7 co-operate.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
