Specific implementation

[0026] Referring to Figures 1-8 , the utility model discloses a simple rope embroidery structure, including needle bar frame 1, at least two needle bar mounting positions are equipped on the needle bar frame 1, wherein at least one mounting position is installed with first needle bar 2, the first needle bar 2 is located on the needle bar position of adjacent side and is equipped with the presser bar 3 that cooperates with first needle bar 2, the bottom of presser bar 3 is equipped with the first presser foot 4 that cooperates with the machine needle on first needle bar 2 and is stitched, the first presser foot 4 is equipped with needle hole 41 or needle slot that can be stitched with the machine needle on first needle bar 2 and passes, and the first presser foot 4 is also equipped with rope guide hole 42 or rope guide slot, the presser bar 3 is equipped with lifting block 31 and driving block 32, and the first needle bar 2 is equipped with lifting block 21 that can cooperate with lifting block 31 and driving block 32. Rope guide hole 42 or rope guide slot is communicated with needle hole 41 or needle slot, and is used for guiding rope 6 into needle hole 41 or needle slot to realize rope embroidery.

[0027] The first presser foot 4 is equipped with needle hole 41 and rope guide hole 42 in the embodiment.

[0028] The first needle bar 2 is usually ordinary needle bar. The installation number of first needle bar 2 can be installed according to actual demand. Participate in the drawing, and the first needle bar 2 of the embodiment is installed with four roots, so that simple rope embroidery color change can be facilitated. In the drawing, the adjacent needle bar position of the right side of each first needle bar 2 is installed with the presser bar 3 that cooperates with the corresponding first needle bar 2.

[0029] The needle bar frame 1 can be installed with all the first needle bars 2 according to actual needs, or can be installed in combination with other functional needle bars according to needs. For example, a flat embroidery second needle bar 7 is installed for pure flat embroidery. The needle bar frame 1 described in the drawings is also provided with at least one second needle bar 7 for flat embroidery, and the second needle bar 7 is provided with a matched flat embroidery presser foot 71. The second needle bar 7 can be selected as the same needle bar as the first needle bar 2, and the difference mainly lies in that the second needle bar 7 is provided with a flat embroidery presser foot 71 matched with the second needle bar 7. The specific driving, color changing and use principle of the first and second needle bars can refer to the needle bar driving and color changing structure and mode in the flat embroidery embroidery of the prior art.

[0030] When the first needle bar 2 needs to be used, the needle bar frame 1 can be driven by the embroidery machine system to make the corresponding first needle bar 2 on the needle bar frame 1 enter the working position and cooperate with the needle bar driver in the working position, so that it can be driven by the needle bar driver to work. The needle bar driver drives the corresponding first needle bar 2 in the working position to reciprocate up and down. When the first needle bar 2 runs downward, the lifting block 21 on the first needle bar 2 moves downward with the first needle bar 2 until the lifting block 21 collides with the driving block 32 of the presser bar 3, the first needle bar 2 drives the driving block 32 downward through the lifting block 21, drives the presser bar 3 downward, thereby driving the first presser foot 4 downward, until the first needle bar 2 reaches the lower limit point and returns upward, the lifting block 21 on the first needle bar 2 returns upward until it collides with the lifting block 31 of the presser bar 3, and the lifting block 31 is lifted upward, thereby driving the presser bar 3 upward, thereby driving the first presser foot 4 upward, and after the first presser foot 4 reaches the upper limit point of the work of the first needle bar 2, one needle embroidery is completed. The needle bar driver continues to drive the first needle bar 2 to move downward and return upward, and the above-mentioned action is repeated to complete the action required for embroidery, which can be applied to flat embroidery or rope embroidery.

[0031] When rope embroidery is needed, the rope is introduced into the needle hole of the first presser foot 4 from the guide hole 42 or the guide groove of the first presser foot 4, so that the needle on the first needle bar 2 can sew the rope on the fabric when the first needle bar 2 reciprocates up and down. In order to facilitate the display, Figures 2-4 In the above-mentioned embodiment, different first needle bars 2 are respectively in different positions.

[0032] As can be seen from the above-mentioned action, when the first needle bar 2 cooperates with the first presser foot 4 to work, the first presser foot 4 is completely driven by the first needle bar 2, and the first presser foot 4 does not need an independent driving motor, and can complete rope embroidery and flat embroidery if necessary. Compared with the prior art, the structure is simple and the cost is low.

[0033] The presser bar 3 is provided with a first presser spring 5 for driving the first presser foot 4. The first presser spring 5 drives the presser bar 3, so that the first presser foot 4 on the presser bar 3 can press on the embroidery fabric, thereby facilitating the embroidery action when the first needle bar 2 moves downward.

[0034] The lifting block 21 is provided with a sliding hole 22 or a sliding slot for accommodating the presser bar 3. In this embodiment, the sliding hole 22 is preferred.

[0035] The lifting block 21 is fixedly installed on the corresponding first needle bar 2 in an adjustable manner, and the specific position of the lifting block 21 on the first needle bar 2 can be adjusted according to actual needs.

[0036] A thread feeding frame (not shown in the figure) is usually installed at the front or top of the needle bar frame 1, and the guide inlet 43 of the guide inlet hole 42 of the thread 6 is arranged at the front of the needle bar frame 1 for the convenience of guiding the thread 6 into the guide inlet hole 42.

[0037] The presser bar 3 is provided with a manual or / and motorized lifting structure. When the thread embroidery is not needed, the presser bar 3 can be lifted by the manual or / and motorized lifting structure to prevent the first presser foot 4 from falling.

[0038] The needle bar frame 1 and the presser bar 3 are provided with a positioning structure for positioning the idle presser bar 3 in an idle position. The positioning structure is used for positioning the idle presser bar 3. When the first needle bar 2 is not in use, the presser bar 3 matched with the first needle bar 2 will also not be in use. The presser bar 3 can be positioned by the positioning structure to prevent the presser bar 3 from falling and to avoid affecting other embroidery procedures.

[0039] As a simplification of this embodiment, the positioning structure includes a positioning bolt 11 connecting the blocking plate 12 provided on the needle bar frame 1 and the idle presser bar 3, and the positioning plate 44 provided on the presser bar 3 is provided with a positioning hole 45 or a positioning slot matched with the positioning bolt 11. The positioning bolt 11 can be installed on the blocking plate 12 and matched with the positioning hole 45 or the positioning slot. Of course, the blocking plate 12 can be provided with a mounting hole for mounting the positioning bolt 11. The positioning plate 44 is usually connected to the presser bar 3 and slides in the guide slot provided on the needle bar frame 1 to prevent the presser bar 3 from rotating. The positioning hole 45 or the positioning slot provided on the positioning plate 44 can greatly simplify the positioning structure. Of course, the positioning structure can also be changed according to the existing technology and actual conditions. The specific positioning structure should be able to position the idle presser bar 3 and prevent it from falling.

[0040] The guide structure (not shown in the figure) matched with the guide inlet hole 42 or the guide slot is also included. The guide structure can guide the thread 6 from the thread feeding frame into the guide inlet hole 42. The guide structure can include necessary guide hooks or guide holes arranged on the thread conveying path. The guide structure can be arranged on a separate mounting frame or on the thread feeding frame.
