[0002] The spindle is one of the main working parts of the braiding machine. It has many structures. Due to the difference between vertical and horizontal types, the structure of the spindle is also different, and the spindles of the braiding machines for various braiding materials are also different. The braiding machine spindle can realize the function of retracting and releasing the silk thread on the braiding machine, and keep the silk thread at a certain tension, so that the silk thread is evenly stressed during the braiding process.

[0003] The Chinese patent application number CN201020552550.1 proposes a spindle of a braiding machine, including a spindle base and a spindle frame arranged on the spindle base, a bobbin is arranged on the spindle frame, a column is extended upward from the spindle frame, the bobbin can be rotatably mounted on the column, and a positioning tooth groove is arranged at the lower end of the bobbin, a switch piece is also slidably arranged on the spindle frame, the upper end of the switch piece can be extended into the positioning tooth groove, a movable frame is rotatably installed on the spindle frame, and one end of the movable frame is connected to the thread end on the bobbin. When the line is tightened, the braided line drives the movable frame to move and disengage the switch piece from the positioning tooth groove; when the line is loose, the movable frame drives the switch piece to insert into the positioning tooth groove and stops the bobbin, thereby gradually tightening the braided line.

[0004] However, since the tension of the braided wire directly acts on the movable frame, the hinge structure of the movable frame will be subjected to a large tension for a long time during use, which is easy to cause deformation after long-term use, thereby affecting the use, and the stability and service life are poor.

[0008] By adopting the above technical solution, when the braided wire is tightened, the winding slider moves toward the first plate body under the pull of the braided wire, and pushes the transmission slider to move toward the first plate body, while compressing the elastic component. At this time, the brake trigger does not trigger the brake; when the braided wire is loose, the winding slider moves toward the second plate body and away from the transmission slider under the pull of the first elastic component, and the transmission slider moves toward the second plate body under the elastic force of the elastic component, and the brake trigger is driven by the linkage component to brake until the braided wire is tightened; the cooperation between the winding slider and the transmission slider makes the braided wire and the brake trigger indirectly linked, and the winding slider and the first elastic component bear the tension of the braided wire, thereby avoiding the brake trigger and the linkage component from being subjected to a large load for a long time, thereby improving the stability and service life of the transmission structure.

[0009] Optionally, the linkage assembly includes a transmission slide rod and a linkage rod, the transmission slide rod is fixedly mounted on the transmission slider, the linkage rod and the brake trigger are coaxially hinged on the second plate body, the linkage rod rotates synchronously with the brake trigger, and one end of the linkage rod away from the brake trigger is hinged to the end of the transmission slide rod away from the first plate body.

[0030] The following is combined with Figure 1-2 This application is described in further detail.

[0031] The present application embodiment discloses a spindle for a knitting machine, referring to Figure 1 , including a first plate body 1, a second plate body 2 and a plurality of connecting columns 3, the connecting columns 3 are fixed between the first plate body 1 and the second plate body 2, and the connecting columns 3 are perpendicular to the first plate body 1 and the second plate body 2, a mounting plate 4 is rotatably mounted on the second plate body 2, a bobbin 5 is detachably mounted between the mounting plate 4 and the first plate body 1, and the bobbin 5 rotates synchronously with the mounting plate 4. The braiding wire is wound around the bobbin 5, and during braiding, the braiding wire pulls the bobbin 5 to rotate and unwind.

[0032] Specifically, refer to Figure 1A winding slider 9 and a transmission slider 10 are provided on the sliding sleeve of the connecting column 3, and the transmission slider 10 is located on the side of the winding slider 9 close to the first plate body 1. A winding wheel 11 is fixed on one side of the winding slider 9. A wire outlet 12 is opened on the first plate body 1. The thread end on the yarn tube 5 passes around the winding wheel 11 and out of the wire outlet 12.

[0033] At the same time, a first elastic member 13 is fixed between the winding slider 9 and the second plate body 2, and the first elastic member 13 is sleeved on the side of the connecting column 3. A brake assembly 6 for stopping the mounting disk 4 is also provided on the second plate body 2, and a brake trigger member 14 for triggering the brake assembly 6 is movably provided on the second plate body 2. The transmission slider 10 is connected with an elastic member 7 and a linkage member 8. The transmission slider 10 and the brake trigger member 14 are linked through the linkage member 8, and the elastic member 7 is used to start the brake trigger member 14.

[0034] When the braided wire is tightened, the winding slider 9 moves toward the first plate body 1 under the pulling force of the braided wire and stretches the first elastic member 13. As the winding slider 9 moves further, the winding slider 9 drives the transmission slider 10 to move toward the first plate body 1. At the same time, the transmission slider 10 compresses the elastic component 7. At this time, the brake trigger 14 does not trigger the brake; when the braided wire is loose, the winding slider 9 will move toward the second plate body 2 under the pulling force of the first elastic member 13, and the transmission slider 10 will move toward the second plate body 2 under the elastic force of the elastic component 7, and drive the brake trigger 14 to move and trigger the brake through the linkage component 8, and the bobbin 5 stops rotating; then the braided wire is gradually tightened, and the winding slider 9 is gradually pulled toward the first plate body 1, driving the transmission slider 10 to move toward the first plate body 1, and driving the brake trigger 14 to stop braking through the linkage component 8. At this time, the braided wire reaches a predetermined tightening state.

[0035] Reference Figure 1 The linkage assembly 8 includes a transmission slide bar 81 and a linkage bar 82. The transmission slide bar 81 is fixedly provided on the transmission slider 10, and the transmission slide bar 81 is arranged parallel to the connecting column 3. One end of the linkage bar 82 is coaxially hinged to the second plate body 2 with the brake trigger 14, and the linkage bar 82 rotates synchronously with the brake trigger 14. At the same time, the end of the linkage bar 82 away from the brake trigger 14 is hinged to the end of the transmission slide bar 81 away from the first plate body 1. When the transmission slider 10 moves, the transmission slide bar 81 moves accordingly, thereby rotating the linkage bar 82 and driving the brake trigger 14 to rotate, so as to realize the switching between the braking state and the non-braking state.

[0036] Reference Figure 1The brake assembly 6 includes two brake pads 61 with an arc-shaped structure. The two brake pads 61 are symmetrically arranged to form a ring structure and are located in the mounting plate 4. At the same time, the ends of the two brake pads 61 on the same side are rotatably mounted on the second plate body 2. The ends of the other ends of the two brake pads 61 form a triggering port 62. The brake trigger member 14 can be rotatably extended into the triggering port 62. A second elastic member 63 is also arranged between the two brake pads 61 for bringing the two brake pads 61 closer to each other.

[0037] When the bobbin 5 is operating normally, the two brake pads 61 contract under the elastic force of the second elastic member 63, the ends of the two brake pads 61 approach each other, and the trigger port 62 contracts accordingly; when braking, the elastic component 7 drives the transmission slider 10 to move and rotates the brake trigger member 14, and the brake trigger member 14 gradually extends into the trigger port 62 and forces the two brake pads 61 to gradually move away from each other until the outer circumferential surfaces of the two brake pads 61 abut against the inner wall of the mounting disk 4, and then the mounting disk 4 stops rotating by the friction between the brake pads 61 and the mounting disk 4, thereby achieving braking.

[0038] Further, refer to Figure 1 The ends of the two brake pads 61 located at the trigger opening 62 are close to each other and are both provided with pulleys 64. The pulleys 64 make it easier for the brake trigger 14 to extend into the trigger opening 62, thereby improving the braking efficiency and accuracy.

[0039] Further, refer to Figure 1 The side of the brake trigger 14 close to the brake pad 61 is a cone-shaped structure. The cone-shaped structure forms a certain guiding effect, which makes it easier for the brake trigger 14 to open the two brake pads 61, thereby improving the braking effect.

[0040] Reference Figure 1 The elastic component 7 includes a limit block 71 and a third elastic member 72. The limit block 71 is fixed on the connecting column 3 and is located on the side of the transmission slider 10 close to the first plate body 1. The two ends of the third elastic member 72 are respectively fixed on the limit block 71 and the transmission slider 10. The end of the transmission slide bar 81 away from the second plate body 2 is passed through the limit block 71 and slidably cooperates with the limit block 71. In this embodiment, the third elastic member 72 is preferably a spring, and the third elastic member 72 is sleeved on the side of the transmission slide bar 81.

[0041] When the braided wire is tightened, the transmission slider 10 moves toward the limit block 71 and compresses the third elastic member 72. When the braided wire is loosened, the third elastic member 72 drives the transmission slider 10 away from the limit block 71 and drives the brake trigger member 14 to brake.

[0042] Reference Figure 1, detection blocks 15 are provided on both sides of the bottom of the winding slider 9, and the detection blocks 15 are used to cooperate with the sensor to detect the position of the winding slider 9. The braiding machine is provided with a corresponding sensor to detect the position of the winding slider 9. When the braided wire is disconnected, the winding slider 9 is close to the second plate body 2 under the elastic force of the first elastic member 13, and its position is closer than when the braided wire is loose. At this time, the sensor detects the detection block 15, which can trigger the equipment to stop to ensure safety.

[0043] Reference Figure 1 The first plate body 1 is provided with a mounting post 16 movably penetrated in the vertical direction, and the mounting post 16 is plugged into one end of the bobbin 5 away from the mounting plate 4. The bobbin 5 can be conveniently installed and removed by the mounting post 16, which is convenient for later replacement and maintenance.

[0044] The implementation principle of a spindle for a braiding machine disclosed in an embodiment of the present application is:

[0045] When the braided wire is in a normal tensioned state, the braided wire pulls the winding slider 9 upward and stretches the first elastic member 13. The winding slider 9 abuts against the transmission slider 10 and drives the transmission slider 10 to move toward the first plate body 1 to compress the third elastic member 72. At this time, the brake trigger member 14 is away from the two brake pads 61, and the bobbin 5 and the mounting plate 4 rotate normally. When the braided wire is in a relaxed state, the winding slider 9 moves under the second plate body 2 under the pulling force of the first elastic member 13, and the transmission slider 10 moves under the third elastic member 72. Under the action of tension, it moves toward the second plate body 2, the transmission slider 10 drives the transmission slider 81 to move, the transmission slider 81 rotates the linkage rod 82 and drives the brake trigger 14 to rotate, the brake trigger 14 extends into the trigger port 62, and opens the two brake pads 61 for braking. At this time, the bobbin 5 and the mounting plate stop rotating until the braided wire is re-tensioned, and the winding slider 9 is pulled toward the first plate body 1, and drives the transmission slider 10 to move toward the first plate body 1, the brake trigger 14 disengages from the trigger port 62, and the bobbin 5 rotates again to release the wire.

[0046] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
