The needle bar driving mechanism drives the needle bar to move up and down. The disc tape presser 123 is connected with a presser driving shaft, and the presser driving shaft is provided with a presser driving block 124. The presser driving block 124 is connected with a presser driving mechanism, which drives the disc tape presser to move up and down. The structures of the needle bar driving mechanism and the presser driving mechanism can refer to the prior art.

[0045] As Figure 1 And Figure 2As shown, the M shaft 11 includes a shaft sleeve 111 and a presser foot mounting seat 112 connected with the shaft sleeve 111, an M shaft secondary pulley 113, and an M shaft driving motor provided on the multi-color disc and belt embroidery machine head. The M shaft driving motor drives an M shaft transmission pulley, and an M shaft transmission belt is provided between the M shaft transmission pulley and the M shaft secondary pulley, so as to drive the M shaft to rotate.

[0046] In addition, the M shaft assembly 1 is provided with a color changing mechanism, which includes at least two presser foot swing lever assemblies installed in the circumferential direction on the presser foot mounting seat 112, i.e., at least a first presser foot swing lever assembly and a second presser foot swing lever assembly. The presser foot swing lever assembly is provided with a swing lever driving part and a presser foot swing lever, and the swing lever driving part drives the presser foot swing lever to swing.

[0047] The presser foot mounting seat 112 is connected with a rotating disc 100, and the rotating disc 100 is axially provided with at least two thread storage mechanisms corresponding to the at least two presser foot swing lever assemblies. Each thread storage mechanism can place a rope or a belt of different color.

[0048] In the embodiment, the axial projection of the presser foot mounting seat is a square structure, and the presser foot swing lever assembly is installed on at least two edges of the square structure, and generally, the presser foot swing lever assembly is installed on four edges, so that four-color disc and belt embroidery can be realized. Of course, the presser foot mounting seat can also be triangular or other shapes.

[0049] The color changing mechanism further includes a presser foot swing lever up-down driving assembly, a presser foot swing lever color changing ring 13 movably connected with the M shaft, and the presser foot swing lever color changing ring 13 is located above the presser foot mounting seat 112 and movably sleeved on the shaft sleeve 111. The presser foot swing lever color changing ring 13 is provided with a color changing secondary pulley, and a color changing driving motor is provided on the multi-color disc and belt embroidery machine head. The color changing driving motor drives a color changing transmission pulley, and a color changing transmission belt is provided between the color changing transmission pulley and the color changing secondary pulley, so as to drive the presser foot swing lever color changing ring 13 to rotate, so as to change color.

[0050] The color changing process of the color changing mechanism is that the presser bar swing lever up-down driving assembly is separated from the swing lever driving part of one of the presser bar swing lever assemblies, and then combined with the swing lever driving part of the other presser bar swing lever assembly. Specifically, the color changing ring 13 is provided with a color changing ring groove 131 in the circumferential direction, and the color changing ring groove 131 is provided with an up-down through interrupt gap 1311. The color changing ring 13 is provided with an axially extending axial guide groove 132 corresponding to the interrupt gap position. The presser bar swing lever up-down driving assembly includes a presser bar swing lever up-down driving member 141, which moves up and down along the axial guide groove 132, and moves up and down through the interrupt gap. The presser bar swing lever up-down driving member 141 is provided with a transmission groove 1411 corresponding to the interrupt gap 1311. The transmission groove 1411 is in a U-shaped structure corresponding to the cross-sectional shape of the color changing ring groove 131. The swing lever driving part cooperates with the transmission groove 1411, and the presser bar swing lever up-down driving member 141 drives the swing lever driving part to move up and down when it moves up and down, thereby driving the presser bar swing lever assembly to swing.

[0051] The presser bar swing lever up-down driving member 141 rotates synchronously with the presser bar swing lever color changing ring 13, and corresponds to the position of the first presser bar swing lever assembly before color changing, and corresponds to the position of the second presser bar swing lever assembly after color changing. Therefore, after the presser bar swing lever color changing ring rotates by a set angle, the presser bar swing lever up-down driving member 141 corresponds to the position of the presser bar swing lever assembly after color changing, so that the presser bar swing lever up-down driving member 141 can drive the second presser bar swing lever assembly.

[0052] When the transmission groove is located in the interrupt gap, the color changing ring groove forms a closed loop structure in the circumferential direction, the swing lever driving part of the first presser bar swing lever assembly is located in the transmission groove, and the swing lever driving part of the second presser bar swing lever assembly is located in the transmission groove. When the presser bar swing lever color changing ring rotates for color changing, the swing lever driving part of the first presser bar swing lever assembly is separated from the transmission groove, and the swing lever driving part of the second presser bar swing lever assembly is connected to the transmission groove after color changing. Before and after color changing, the transmission groove 1411 is always connected to one of the swing lever driving parts, so that the transmission groove 1411 can drive one of the swing lever driving parts before and after color changing.

[0053] Specifically, the presser bar swing rod up-down driving assembly further comprises a sliding ring 142 sleeved on the presser bar swing rod color changing ring, a presser bar swing rod transmission shaft 144 and a clamping transmission member 143. The presser bar swing rod up-down driving member 141 is connected with the sliding ring 142, and the sliding ring 142 drives the presser bar swing rod up-down driving member 141 to move up and down. The sliding ring 142 is provided with an annular clamping groove 1421, and the clamping transmission member 143 is provided with an arc-shaped insertion part 1431 which is clamped with the annular clamping groove 1421. The lower end of the presser bar swing rod transmission shaft 144 is connected with the clamping transmission member 143, and the upper end is connected with the linear driver. In this way, the linear driver serves as a driving source, and the presser bar swing rod transmission shaft 144, the clamping transmission member 143, the sliding ring 142 and the presser bar swing rod up-down driving member 141 are sequentially linked.

[0054] As described above, at least two presser bar swing rod assemblies are arranged along the circumference of the presser bar mounting seat. Figure 9 As shown in the drawings, in the embodiment, the first presser bar swing rod assembly is a rope nozzle presser bar swing rod assembly 3, and the second presser bar swing rod assembly is a belt nozzle presser bar swing rod assembly 2. The rope nozzle presser bar swing rod assembly 3 and the belt nozzle presser bar swing rod assembly 2 are distributed at intervals of 180 degrees along the circumference of the presser bar mounting seat 112. In the prior art, the belt nozzle swing rod assembly and the rope nozzle presser bar swing rod assembly have similar structures. The belt nozzle swing rod assembly comprises a belt nozzle swing rod provided with a belt nozzle and a belt nozzle up-down slider for driving the belt nozzle swing rod to swing. The belt nozzle up-down slider is detachably connected with the presser bar swing rod up-down driving member. The rope nozzle swing rod assembly comprises a rope nozzle swing rod provided with a rope nozzle and a linear sliding member for driving the rope nozzle swing rod to swing. The linear sliding member is detachably connected with the presser bar swing rod up-down driving member. The belt nozzle up-down slider and the linear sliding member can slide up and down when connected with the presser bar swing rod up-down driving member. When the presser bar swing rod color changing ring changes color, it rotates and drives the presser bar swing rod up-down driving member to rotate synchronously, so that the first presser bar swing rod assembly is separated from the presser bar swing rod up-down driving member, and the second presser bar swing rod assembly is connected with the presser bar swing rod up-down driving member. In this way, through color changing, disc belt rope embroidery and disc belt belt embroidery can be performed separately, and the quality of the embroidery can be guaranteed while realizing multi-color disc belt embroidery.

[0055] The structure of the rope nozzle foot pressing swing rod assembly in the prior art can refer to the prior application, that is, the Chinese invention patent with the authorization announcement number CN212294009U. The swing driving assembly includes a driving motor and a transmission mechanism connected with the output shaft of the driving motor. The disc belt winding fork moves up and down linearly through the transmission mechanism, and the disc belt winding fork sleeve drives the disc belt swing link to reciprocate. The disc belt winding fork sleeve is connected with a disc belt winding fork sleeve connecting block, the disc belt winding fork sleeve connecting block is provided with a U-shaped groove, the disc belt swing link is rotatably connected with a disc belt swing link ball, the disc belt swing link ball cooperates with the U-shaped groove, and the disc belt swing link ball can slide in the U-shaped groove to realize the swing of the disc belt swing link under the driving of the disc belt winding fork sleeve connecting block. However, the gap between the disc belt swing link ball and the U-shaped groove is large, which cannot guarantee the uniform speed of the swing of the disc belt swing link, and affects the improvement of the disc belt embroidery quality.

[0056] In view of the above problems existing in the prior art, the specific structure of the rope nozzle foot pressing swing rod assembly in the embodiment is shown in Figure 7 and Figure 8 The rope nozzle foot pressing swing rod assembly 3 includes a rope nozzle assembly mounting bracket 31, a rope nozzle swing rod 32 hinged to the rope nozzle assembly mounting bracket, a linear sliding part 33 capable of sliding linearly up and down on the rope nozzle assembly mounting bracket, a swing part 34 driving the rope nozzle swing rod 32 to swing, and a transmission conversion part provided between the linear sliding part 33 and the swing part 34. The transmission conversion part is used to convert the linear sliding of the linear sliding part into the swing of the swing part. Unlike the prior art, the transmission conversion part includes a first rack 331 provided on the linear sliding part 33 and a first gear 341 provided on the swing part 34, and the first gear 341 is engaged with the first rack 331. The linear sliding of the linear sliding part is converted into the swing of the swing part by the engagement of the rack and the gear, and then the rope nozzle swing rod is driven to swing. Since the machining precision and engagement precision of the rack and the gear can be designed to be high, the uniform speed of the swing of the swing part can be guaranteed, and the disc belt embroidery quality is improved.

[0057] Specifically, the rope nozzle swing rod 32 includes a rope nozzle swing rod A 321, a rope nozzle swing rod B 322, and a rope nozzle 323. The rope nozzle swing rod A 321 and the rope nozzle swing rod B 322 can be integrated or separately arranged. When they are separately arranged, the rope nozzle swing rod A 321 and the rope nozzle swing rod B 322 are positioned by the cooperation of positioning grooves and positioning protrusions, and then fixed by bolts.
