DETAILED DESCRIPTION

[0020] The present invention is further described below through specific implementation methods.

[0021] Reference Figures 1 to 6 As shown, a yarn rack includes a rotating frame 1, a rotating drive 2, a yarn hanging assembly 3, a yarn guide frame 4, and a clamping yarn cutter 5.

[0022] The rotating frame 1 is positioned to one side of the yarn guide frame 4. It is equipped with at least two sets of yarn hanging assemblies 3, each oriented in different directions. When facing the yarn guide frame 4, the yarn hanging assemblies 3 are in the yarn-using state; when facing in other directions, they are in the yarn-ready state. The rotating frame 1 rotates about its axis via a rotary drive 2, switching each set of yarn hanging assemblies 3 between the yarn-using and yarn-ready states. Each set of yarn hanging assemblies 3 includes a screw-nut assembly 31, a guide 32, a yarn hanging rod 33, and a screw drive 34. The screw-nut assembly 31 includes a screw 311 and several nut racks 312, each of which is mounted on the screw 311 in an interval arrangement. The guide members 32 are provided with several, including a pivot shaft 321 and a guide hole 322 provided on the pivot shaft 321. The axis of the guide hole 322 is perpendicular to the axis of the pivot shaft 321. The guide member 32 is rotatably connected to the rotating frame 1 through the pivot shaft 321; a plurality of yarn hanging rods 33 are provided, one end of the yarn hanging rod 33 is rotatably connected to the nut frame 312, and the other end passes through a guide hole 322 of a guide member 32; the screw drive 34 drives each nut frame 312 to rise and fall synchronously through the rotation of the screw 311, thereby driving the yarn hanging rod 33 to swing up and down.

[0023] The yarn guide frame 4 includes a fixed frame 41 and a lifting rod 42. A plurality of clamping yarn cutters 5 are mounted vertically on the fixed frame 41. Each clamping yarn cutter 5 is connected to the fixed frame 41 via a fixed plate 51. The lifting rod 42 is connected to the lifting plate 52 of each clamping yarn cutter 5. The vertical movement of the lifting rod 42 drives the clamping yarn cutters 5 to move synchronously. The lifting rod 42 is provided with a driver 59 for driving the lifting rod 42 up and down. The driver 59 is a cylinder, a motor, or a magnetic switch.

[0024] The yarn clamping cutter 5 includes a fixed plate 51, a lifting plate 52, a movable clamping plate 53, a cutter 54, a yarn feed hole plate 55, a yarn guide tube 56, a spring 57, and a guide rod 58. The movable clamping plate 53 is arranged between the fixed plate 51 and the lifting plate 52, and a spring 57 is arranged between the movable clamping plate 53 and the lifting plate 52. A through hole 521 is opened on the lifting plate 52, and a guide rod 58 is passed through the through hole 521. One end of the guide rod 58 is connected to the movable clamping plate 53, and the other end passes through the through hole 521 and is provided with a limit head 581. The spring 57 is sleeved outside the guide rod 58, and the two ends of the spring 57 respectively press against the lifting plate 52 and the movable clamping plate 53; the cutter 54 includes a movable blade 541 and the static blade 542, the dynamic blade 541 is installed on the lifting plate 52, the static blade 542 is installed on the fixed plate 51, and the dynamic blade 541 and the static blade 542 are arranged opposite to each other; the yarn passes between the fixed plate 51 and the movable clamping plate 53, and between the dynamic blade 541 and the static blade 542, the lifting plate 52 moves toward the fixed plate 51, which will drive the movable clamping plate 53 and the fixed plate 51 to clamp the yarn, and then compress the spring 57 to make the dynamic blade 541 and the static blade 542 shear the yarn.

[0025] The yarn feed hole plate 55 is arranged on one side of the fixed plate 51, and the yarn guide tube 56 is arranged on the other side of the fixed plate 51. The yarn passes through the yarn feed hole plate 55 and enters the yarn guide tube 56. The yarn between the yarn feed hole plate 55 and the yarn guide tube 56 is located between the fixed plate 51 and the movable splint 53, and between the movable blade 541 and the static blade 542.

[0026] The working principle of this application is further explained below with a specific working process.

[0027] Each yarn hanging rod 33 in the yarn hanging assembly 3 in the yarn using state is in an inclined upward state, and a yarn bobbin is hung on each yarn hanging rod 33. The yarn 6 of a yarn bobbin passes through a yarn feed hole plate 55 of a clamping yarn cutter 5 and then passes through the yarn guide tube 56 to the textile equipment.

[0028] When the yarn 6 on the bobbin is about to be used up, the textile equipment stops for the yarn change process. The lifting rod 42 descends, driving the clamping and cutting devices 5 to operate synchronously. The clamping and cutting devices 5 operate as follows: the lifting plate 52 descends, first the movable clamping plate 53 approaches the fixed plate 51 and clamps the yarn 6. The lifting plate 52 continues to descend, compressing the spring 57, causing the movable blade 541 to move toward the stationary blade 542, shearing the yarn 6.

[0029] The rotary drive 2 rotates the rotating frame 1, rotating the original yarn hanging assembly 3 from the yarn-using state to the yarn-ready state. A new yarn bobbin is pre-placed on the yarn hanging assembly 3 in the yarn-ready state. The lifting rod 42 rises, causing each clamping and cutting device 5 to release the yarn 6. The yarn 6 joining step is then performed manually or robotically. After the yarn joining step is completed, the textile machine can be restarted.

[0030] The nut rack 312 is lowered to make the yarn hanging rod 33 swing from the oblique downward direction to the oblique upward direction, and the new yarn bobbin is placed on each yarn hanging rod 33 manually or by a robot for standby use.

[0031] The above is only a specific implementation of the present invention, but the design concept of the present invention is not limited to this. Any non-substantial changes to the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.
