However, when actively paying out the wire, it is necessary to first align the hexagonal plug with the hexagonal cap, and then lift the motor to fix the connection, which is inconvenient to operate. In addition, the size of the conical plug is fixed, and not only does it need to be pressed hard to fix it when inserting it into the winding drum, but it is also difficult to fix winding drums with different inner diameters, which is inconvenient to use. In view of the deficiencies in the prior art, the utility model discloses a wire arrangement device for sewing thread processing to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example: Reference Figure 1-4The described wire arrangement device for sewing thread processing comprises a support block 1, a fixed block 2 is installed on the side of the support block 1, a servo motor 3 is installed on the top of the fixed block 2, a lower rectangular box 4 is installed on the output end of the servo motor 3, a rectangular block 5 is slidably installed in the lower rectangular box 4, an elastic mechanism is provided at the bottom of the rectangular block 5, a lifting block 7 is provided on the right side of the support block 1, a rotating hole is provided on the top of the lifting block 7, a rotating rod 9 is rotatably installed on the rotating hole, an upper rectangular box 10 and a support plate 11 are respectively installed at the bottom and top of the rotating rod 9, a groove is provided on the top of the support plate 11, a positive and negative threaded rod 12 is rotatably installed on the relative inner wall of the groove, a knob is installed at one end of the positive and negative threaded rod 12, two threaded blocks 13 are threadedly sleeved on the positive and negative threaded rod 12, and extrusion blocks 14 are installed on the top of the two threaded blocks 13, and a driving mechanism for moving the lifting block 7 is provided on the support block 1.

[0023] By means of the above mechanism, when in use, the bobbin of sewing thread is first placed on the support plate 11, and the squeezing block 14 is placed in the bobbin, and then the knob is turned. The rotation of the knob will cause the positive and negative threaded rods 12 to rotate, and the rotation of the positive and negative threaded rods 12 will cause the two threaded blocks 13 to move away from or approach each other, and the two threaded blocks 13 approaching each other will cause the two squeezing blocks 14 to move away from or approach each other, so that bobbins with different inner diameters can be squeezed and fixed without pressing hard to insert. When active wire release is required, the lifting block 7 is first moved down, and when the lifting block 7 moves down, the rotating rod 9 moves down, and the upper rectangular box 10 moves down When the rectangular block 5 is not aligned with the upper rectangular box 10, the upper rectangular box 10 moves downward to squeeze the rectangular block 5 to make it enter the lower rectangular box 4. When the upper rectangular box 10 contacts the lower rectangular box 4, the servo motor 3 is turned on. The output of the servo motor 3 causes the lower rectangular box 4 to rotate. The rotation of the lower rectangular box 4 causes the rectangular block 5 to rotate. When the rectangular block 5 rotates to correspond to the upper rectangular box 10, the elastic mechanism resets the rectangular block 5. The rotation of the rectangular block 5 causes the upper rectangular box 10 to rotate, thereby actively paying out the line. Therefore, it can be connected to the servo motor 3 for active paying out without adjusting the alignment back and forth, which is easy to use.

[0024] like Figure 1 The driving mechanism includes a lifting groove opened on the side of the support block 1, a threaded rod 6 is rotatably installed relative to the inner wall of the lifting groove, a handle is installed on the top of the threaded rod 6, the lifting block 7 is threadedly sleeved on the threaded rod 6, and a self-fixing unit compatible with the threaded rod 6 is provided on the support block 1. The advantage of this arrangement is that the lifting block 7 is easy to move through the arrangement of the threaded rod 6 and the handle.

[0025] Specifically, the rotation of the handle will cause the threaded rod 6 to rotate, and the rotation of the threaded rod 6 will cause the lifting block 7 to move up and down, thereby causing the rectangular block 5 to be located in the upper rectangular box 10, thereby eliminating the need to carry the lifting block 7, and facilitating use.

[0026] like Figure 2 The relative inner wall of the lifting groove is installed with a guide rod 8, and the top of the lifting block 7 is provided with a guide hole, and the guide rod 8 passes through the guide hole. The advantage of this arrangement is that the setting of the guide rod 8 facilitates the lifting block 7 to move in the horizontal direction.

[0027] like Figure 4 The self-fixing unit includes a ratchet 16 sleeved on the threaded rod 6, a pawl 17 adapted to the ratchet 16 is rotatably installed on the top inner wall of the lifting groove, a blocking plate and an elastic sheet 18 are installed on the side inner wall of the lifting groove, and the other end of the elastic sheet 18 is installed on the side of the pawl 17. A limiting element is provided on the support block 1 to keep the pawl 17 at a certain angle. The advantage of such a setting is that through the setting of the ratchet 16, the pawl 17, the blocking plate and the elastic sheet 18, the threaded rod 6 can be easily self-fixed so that it cannot rotate in the opposite direction.

[0028] Specifically, when the threaded rod 6 rotates counterclockwise to lower the lifting block 7, the ratchet 16 will also rotate counterclockwise. At this time, the pawl 17 will avoid. When the upper rectangular block 10 contacts the lower rectangular block 4, the ratchet 16 cannot rotate clockwise under the action of the pawl 17 and the blocking plate. The inability of the ratchet 16 to rotate clockwise will prevent the lifting block 7 from rotating in the opposite direction, thereby self-fixing the lifting block 7, thereby avoiding the situation where the servo motor 3 generates vibration during operation and causes the lifting block 7 to move.

[0029] like Figure 4 The limiting element includes a limiting rod 20 installed on the side of the support block 1, a pull rope 19 is installed on the side of the pawl 17, a rope hole begins to be provided on the side of the support block 1, the other end of the pull rope 19 passes through the rope hole and is installed with a ring. The advantage of this arrangement is that the pawl 17 can be easily limited by the arrangement of the pull rope 19, the ring and the limiting rod 20.

[0030] Specifically, when the fixation needs to be released, the pull rope 19 is pulled first. The movement of the pull rope 19 will cause the pawl 17 to move. The rotation of the pawl 17 will release the limit on the ratchet 16. Then the limit ring is put on the limit rod 20 to prevent the pawl 17 from resetting under the action of the elastic sheet 18. Therefore, there is no need to keep pulling the pull rope 19 to make the pawl 17 always release the limit on the ratchet 16, which is easy to use.

[0031] like Figure 2 The elastic mechanism includes a plurality of springs 21 installed at the bottom of the rectangular block 5, and the other ends of the plurality of springs 21 are installed on the bottom inner wall of the lower rectangular box 4. The advantage of such an arrangement is that, through the arrangement of the springs 21, when the rectangular block 5 is aligned with the upper rectangular box 10, the rectangular block 5 is reset under the action of the springs 21, so that the rectangular block 5 enters the upper rectangular box 10.

[0032] like Figure 3 As described, a threaded hole is formed at the bottom of the support plate 11, and a fixing bolt 15 is installed in the threaded hole. The end of the fixing bolt 15 is tightly pressed against the positive and negative threaded rod 12. The advantage of such a setting is that the setting of the fixing bolt 15 facilitates the fixing of the positive and negative threaded rod 12, thereby avoiding the situation in which the positive and negative threaded rod 12 rotates during use and causes the extrusion block 14 to move.

[0033] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
