A Chinese invention patent application, CN113584749 A, discloses a coiling embroidery device and a coiling embroidery control method. The device comprises a housing, a needle bar, a presser foot, and a material tray. The needle bar is sequentially sleeved with a presser foot sleeve, a fixing sleeve, and a shaft sleeve. The fixing sleeve is fixed to the housing. The presser foot comprises a presser foot mounting member connected to the presser foot sleeve and a presser foot rotation drive mechanism. The material tray comprises a material tray frame and a material tray drive mechanism. The material tray drive mechanism rotates the shaft sleeve, which in turn rotates the material tray frame. The presser foot rotation drive mechanism rotates the presser foot sleeve, which in turn rotates the presser foot mounting member. When the feed connector rises, it lifts one side of the feed frame, while the other side of the feed frame swings away from the material tray. When the feed connector descends, it pulls one side of the feed frame downward, while the other side swings toward the material tray. This swinging method for tightening or loosening the tape is complex and prone to malfunction. [Utility Model Content]

[0027] Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be understood to indicate or imply relative importance or to implicitly indicate the quantity of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0028] Referring to the existing tape embroidery machine head structure, the tape reel is rotatably mounted on a reel bracket, which stores a roll of tape. The reel bracket is mounted on the M-axis assembly. During the tape embroidery process, the tape is drawn from the reel and fed into the presser foot or nozzle. Typically, at least two reel brackets are installed. For example, two reel brackets are arranged symmetrically on the left and right sides of the M-axis assembly.

[0029] In order to achieve the tension and relaxation of the material belt, refer to Figures 1 to 3 As shown, the tape embroidery machine head is provided with a tape tensioning mechanism 2, which includes:

[0030] The belt slot 21 is mounted on a belt slot bracket 22 , and the material belt is led out from the material belt roll and passes through the belt slot and protrudes radially outward from the M-axis assembly 1 ;

[0031] A slotted bracket 22, wherein the slotted bracket 22 is provided with a first guide hole, and the first guide hole is movably nested on the M shaft 11 and can move up and down along the axial direction;

[0032] The belt slot lifting component is connected to the belt slot bracket 22. The belt slot lifting component drives the belt slot bracket 22 to slide up and down along the M axis, and drives the belt slot 21 to rise and fall. When the belt slot rises, the material belt is tightened, and when it falls, the material belt is loosened.

[0033] Compared with the existing swinging method, the technical solution in this embodiment realizes the tightening or loosening of the material belt by lifting. The lifting structure is also easier to implement, has a simpler structure, and is less prone to failure.

[0034] Specifically, the slotted lifting assembly includes a first motor 27 and a lifting transmission structure. The first motor 27 drives the slotted bracket to rise and fall via the lifting transmission structure. The lifting transmission structure includes a first synchronous belt assembly and a lifting rod 24. The first synchronous belt assembly includes a first driving pulley, a first driven pulley, and a first synchronous belt 26 connecting the first driving pulley and the first driven pulley. The lifting rod 24 is connected to the first synchronous belt 26, which drives the lifting rod 24 up and down, and the lifting rod 24 drives the slotted bracket 22 up and down. The first synchronous belt 26 includes a vertical section connected to the lifting rod. The first synchronous belt moves vertically along the vertical section to drive the lifting rod to rise and fall. By arranging the synchronous pulleys, a vertical section is formed on the first synchronous belt, which also serves to tension the synchronous pulleys. A first lifting block 25 is connected between the vertical section and the upper end of the lifting rod. The lower end of the lifting rod is connected to a first fork arm 23, and a first fork groove 221 is provided on the slotted bracket 22. The first fork arm 23 is engaged with the first fork groove 221. In this way, the slotted bracket 22 can be driven to rise and fall through the cooperation of the first fork arm 23 and the first fork groove 221, but will not interfere with the rotation of the slotted bracket.

[0035] Furthermore, the lifting rod 24 is connected to a lifting guide structure, and the lifting guide structure guides the lifting rod 24. The lifting guide structure includes a second guide hole 361, which is slidably embedded in the outer side of the lifting rod.

[0036] For the coiling embroidery machine head, the coiling embroidery machine head can be provided with the above-mentioned material belt tensioning mechanism. In addition, the coiling embroidery machine head also includes a presser foot mechanism 3.

[0037] In some embodiments, the presser foot mechanism 3 includes:

It can be understood that the rotating part 321 and the lifting part 322 can be movably nested up and down through a key.

[0039] The presser foot lifting assembly is used to drive the lifting part to move up and down, and drive the presser foot body to move up and down.

[0040] The presser foot rotation drive assembly is used to drive the rotating part to rotate and drive the lifting part to rotate synchronously, thereby driving the presser foot to rotate.

[0041] Furthermore, the presser foot mechanism 3 includes a second lifting block 36 for driving the presser foot to rise and fall, and the second lifting block is provided with a second guide hole 361. The presser foot mechanism also includes a presser foot lifting seat 35, and the presser foot lifting seat 35 is provided with an upper limit portion 351 and a lower limit portion 352. The second guide hole 361 is provided between the upper limit portion and the lower limit portion, and is limited in upper and lower positions by the upper limit portion and the lower limit portion.

[0042] Specifically, the presser foot lifting assembly includes a second motor 38 and a second synchronous belt assembly. The second motor drives the lifting portion to rise and fall through the second synchronous belt assembly, thereby driving the presser foot body 31 to rise and fall. The second synchronous belt assembly includes a second driving pulley, a second driven pulley, and a second synchronous belt 37 connecting the second driving pulley and the second driven pulley. The second synchronous belt has a vertical section. Similarly, a vertical section can be formed on the second synchronous belt by arranging other synchronous pulleys.

[0043] In addition, the presser foot rotation drive assembly includes a fourth motor 33 and a fourth synchronous belt assembly 34 , and the fourth motor 33 drives the rotating part to rotate through the fourth synchronous belt assembly 34 .
