Description

Technical Field

[0001] This application belongs to the field of braiding machine component manufacturing technology, specifically a braiding machine thread guiding device. Background Technology

[0002] like Figure 1 As shown, during the weaving process, the braiding machine 1 continuously consumes the braiding thread 2, which is wound on the yarn roller 3. Therefore, during this continuous consumption, the braiding thread 2 moves along the axial direction of the yarn roller 3. The traditional method for addressing this axial movement of the braiding thread 2 in the braiding machine 1 is as follows: a fixed pulley 4 is installed along the path of the braiding thread 2, allowing it to reach the weaving station after passing through the pulley 4. The direction of movement of the braiding thread 2 on the fixed pulley 4 is perpendicular to the axis of the yarn roller 3. This results in two serious drawbacks during the movement of the braiding thread 2: 1. The braiding thread 1 may fall off the top pulley 4; 2. The braiding thread 1 may rub against the sidewall of the yarn groove on the fixed pulley 4, causing significant vibration and affecting product production. Utility Model Content

Detailed Implementation

[0021] like Figures 2-4 As shown, a yarn feeding device for a braiding machine includes a first yarn feeder 5, a second yarn feeder 6, a mounting frame 7, and a thread sewing frame 8. Both the first and second yarn feeders 5 and 6 are rotatably mounted on the mounting frame 7. The rotation axis of the first yarn feeder 5 is perpendicular to the rotation axis of the second yarn feeder 6. A predetermined distance exists between the first and second yarn feeders 5. A common tangent A9 exists between the bottom wall of the yarn groove of the first yarn feeder 5 and the bottom wall of the yarn groove of the second yarn feeder 6. The common tangent A9 is perpendicular to both the rotation axes of the first and second yarn feeders 5. The length line of the thread exit seam on the thread sewing frame 8 is parallel to both the end face of the second yarn feeder 6 and the end face of the first yarn feeder 5. The thread exit seam on the thread sewing frame 8 is located directly below the yarn groove on the second yarn feeder 6.

[0022] In the embodiment, after the end of the braiding wire 2 is pulled out from the wire roller 3, it passes through the wire slot and then the second wire conveying wheel 6, and finally enters the braiding position on the braiding machine 1. Then, during the process of conveying the braiding wire 2 to the braiding position on the braiding machine 1, if the braiding wire 2 moves along the axis of the wire roller 3 during the process of continuously releasing the wire by the wire roller 3, the plane of the swing of the braiding wire 2 is always parallel to the end surface of the second wire conveying wheel 6, so that the braiding wire 2 does not rub against the side wall of the wire slot on the second wire conveying wheel 6; and the braiding wire 2 that goes out of the second wire conveying wheel 6 enters the braiding position through the first wire conveying wheel 5. Since the braiding wire 2 that goes out of the second wire conveying wheel 6 is in a stable direction, the braiding wire 2 on the first wire conveying wheel 5 does not rub against the side wall of the wire slot on the first wire conveying wheel 5 at all times, and the braiding wire 2 does not fall off from the first wire conveying wheel 5.

[0023] As a preferred mode, the mounting frame 7 comprises a mounting base 10, a support column 11 and a support plate 12, the support column 11 and the support plate 12 are both vertically arranged on the mounting base 10, the top end of the support column 11 is rotatably arranged with the first wire conveying wheel 5, and the side wall of the support plate 12 is rotatably arranged with the second wire conveying wheel 6. After such arrangement, the relative position relationship between the first wire conveying wheel 5 and the second wire conveying wheel 6 is fixed, so that during the process of mounting the first wire conveying wheel 5 and the second wire conveying wheel 6 on the braiding machine 1, it is only necessary to directly mount the mounting base 10 on the braiding machine.

[0024] As a preferred mode, the middle line between the two side walls of the wire slot on the first wire conveying wheel 5 is in the same plane as the slot bottom of the wire slot on the second wire conveying wheel 6 that is located at the top end. Such arrangement is to ensure that the braiding wire 2 located on the first wire conveying wheel 5 and the braiding wire 2 located on the second wire conveying wheel 6 are both only in contact with the slot bottom of the corresponding wire slot and not rub against the side wall of the corresponding wire slot.

[0025] As a preferred mode, the wire sewing frame comprises a frame body 13, a guide rod 14, a sliding block 15 and a length direction position stabilizer, the guide rod 14 is arranged on the frame body 13, the sliding block 15 is slidingly arranged between the two ends of the guide rod 14, the sliding block 15 is slidingly connected with the frame body 13, the length direction position stabilizer is arranged on the sliding block 15, the length of the guide rod 14 is the length of the wire slot of the wire sewing frame 8, and the path of the movement of the sliding block 15 and the length direction position stabilizer between the two ends of the guide rod 14 forms the wire slot. After such arrangement, during the process of releasing the wire by the wire roller 3, the sliding block 15 can slide when the braiding wire 2 swings, and the relative position relationship between the sliding block 15 and the second wire conveying wheel 6 is relatively fixed, so that the situation that the braiding wire 2 falls off from the second wire conveying wheel 6 can be prevented.

[0026] There are three ways to set the length direction position stabilizer:

[0027] The first design: the length direction position stabilizer is a through hole 16, which is arranged on the sliding block 15, and the axis of the through hole 16 is parallel to the axis of the first wire wheel 5. After such setting, the knitting line 2 is threaded through the through hole 16 during use, so that the sliding block 15 limits the swing of the knitting line 2 beyond the preset range.

[0028] The first design: the length direction position stabilizer is a through hole 16, which is arranged on the sliding block 15, and the axis of the through hole 16 is parallel to the axis of the first wire wheel 5. After such setting, the knitting line 2 is threaded through the through hole 16 during use, so that the sliding block 15 limits the swing of the knitting line 2 beyond the preset range.

[0029] The first design: the line sewing frame is a mounting plate 18, and the mounting plate 18 is provided with a through slot 19, the length line of the through slot 19 is parallel to the end face of the second wire wheel 6 and the end face of the first wire wheel 5, and the through slot 19 is the wire outlet.
