The guide rope hole 42 or the guide rope groove is connected to the needle hole 41 or the needle groove, and is used to guide the rope 6 into the needle hole 41 or the needle groove to realize rope embroidery.

[0027] In this embodiment, the first presser foot 4 is provided with a needle hole 41 and a guide rope hole 42 .

[0028] The first needle bar 2 is usually an ordinary needle bar. The number of first needle bars 2 installed can be installed according to actual needs. Referring to the attached drawings, four first needle bars 2 are installed in this embodiment, which can facilitate the color change of simple cord embroidery. The adjacent needle bar position on the right side of each first needle bar 2 in the attached drawings is installed with a presser foot rod 3 that matches the corresponding first needle bar 2.

[0029] The needle bar frame 1 can be equipped with all the first needle bars 2 according to actual needs, or can be installed in combination with needle bars with other functions according to needs. For example, a second needle bar 7 for flat embroidery purely used for flat embroidery is installed. The needle bar frame 1 described in the attached 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 matching flat embroidery presser foot 71. The second needle bar 7 can be the same needle bar as the first needle bar 2, and the main difference is that the second needle bar 7 is provided with a flat embroidery presser foot 71 that matches the second needle bar 7. The specific driving, color changing and use principles of the first and second needle bars can refer to the needle bar driving and color changing structures and methods in the flat embroidery of the prior art.

[0030] When the first needle bar 2 is needed, the needle bar frame 1 can be driven by the embroidery machine system, so that the corresponding first needle bar 2 on the needle bar frame 1 enters the working position and cooperates with the needle bar driver located at the working position, and can be driven to work by the needle bar driver. 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 moves 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 foot rod 3. The first needle bar 2 drives the driving block 32 downward through the lifting block 21, drives the presser foot rod 3 downward, thereby driving the first presser foot 4 downward, until the first needle bar 2 descends to the lower dead point and then returns to the upper direction. The lifting block 21 on the first needle bar 2 that returns to the upper direction collides with the lifting block 31 of the presser foot rod 3, lifts the lifting block 31 upward, drives the presser foot rod 3 upward, thereby driving the first presser foot 4 upward, and after ascending to the upper dead point of the first needle bar 2, one stitch of embroidery is completed. The needle bar driver continues to drive the first needle bar 2 downward and returns upward, and repeatedly completes the actions required for embroidery, which can be suitable for flat embroidery or rope embroidery.

[0031] When cord embroidery is required, the cord is introduced into the needle hole of the first presser foot 4 from the cord guide hole 42 or the cord guide groove of the first presser foot 4, so that the needle on the first needle bar 2 can sew the cord onto the fabric when the first needle bar 2 moves up and down reciprocatingly. Figure 2-4 In the embodiment, different first needle bars 2 are respectively located at different positions.

[0032] It can be seen from the above actions that when the first needle bar 2 and the first presser foot 4 work together, the first presser foot 4 is completely driven by the first needle bar 2. The first presser foot 4 does not require an independent driving motor and can complete rope embroidery and, if necessary, flat embroidery. Compared with the prior art, it has a simple structure and low cost.

[0033] The presser foot rod 3 is provided with a first presser foot spring 5 for driving the first presser foot 4. The first presser foot spring 5 drives the presser foot rod 3 so that the first presser foot 4 on the presser foot rod 3 can be pressed on the embroidery fabric, so as to facilitate 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 groove for accommodating the presser foot rod 3. In this embodiment, the sliding hole 22 is preferred.

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

[0036] The rope feeding frame (not shown) is usually installed in front of or above the needle bar frame 1. In order to facilitate rope feeding, the introduction port 43 of the introduction hole 42 of the rope 6 is set in front of the needle bar frame 1.

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

[0038] A positioning structure for positioning the idle presser foot rod 3 in an idle position is provided between the needle bar frame 1 and the presser foot rod 3. The positioning structure is used to position the idle presser foot rod 3. When the first needle bar 2 stops being used, the presser foot rod 3 matched with the first needle bar 2 will also stop being used. The presser foot rod 3 can be positioned by the positioning structure to prevent the presser foot rod 3 from falling and affecting other embroidery programs.

[0039] As a simplification of this implementation case, the positioning structure includes a positioning bolt 11 connecting the baffle plate 12 provided on the needle bar frame 1 and the presser foot rod 3 in the idle position, and a positioning plate 44 provided on the presser foot rod 3 is provided with a positioning hole 45 or a positioning groove that cooperates with the positioning bolt 11. The positioning bolt 11 can be installed on the baffle plate 12 to cooperate with the positioning hole 45 or the positioning groove. Of course, the baffle plate 12 can be provided with a mounting hole for installing the positioning bolt 11. The positioning plate 44 is usually connected to the presser foot rod 3, and slides to cooperate with the guide groove provided on the needle bar frame 1 to prevent the presser foot rod 3 from rotating. Providing the positioning hole 45 or the positioning groove on the positioning plate 44 can greatly simplify the positioning structure. Of course, the positioning structure can also be changed accordingly according to the existing technology combined with the actual situation, specifically to be able to position the idle presser foot rod 3 to prevent it from falling.

[0040] The guide rope structure (not shown) matched with the guide rope hole 42 or the guide rope groove is also included, and the guide rope structure can facilitate the guide rope 6 to be introduced from the rope conveying frame into the introduction hole 42. The guide rope structure can include necessary guide hooks or guide holes arranged on the rope conveying path. The guide rope structure can be arranged on a separate mounting frame or can also be arranged on the rope conveying frame.
