Description

Technical Field

[0001] This utility model relates to the field of embroidery machine technology, specifically to a semi-independent motor presser foot head. Background Technology

[0002] An embroidery machine is a mechanical device used for fine embroidery on fabrics. It mainly uses computer control to move the embroidery needles to embroider pre-designed patterns onto the fabric.

[0003] During the embroidery process, the presser foot of the embroidery machine first contacts and presses down on the fabric. Then, the needle, carrying the top thread, pierces the bottom of the fabric to form a loop. A rotary hook mechanism hooks the loop and interweaves it with the bottom thread to form a lockstitch. The needle rises and resets, completing a single embroidery movement. Finally, the presser foot rises again, and the fabric feeding mechanism moves the fabric to allow the needle to perform the next embroidery movement. Currently, embroidery machine heads typically have two drive methods for the presser foot and needle. One method uses separate drive sources for the presser foot and needle, which, while automatically adapting to fabrics of different thicknesses, suffers from poor synchronization between their movements. The other method uses the same drive source, achieving synchronization between the presser foot and needle. However, because this synchronization is forced, parameters cannot be independently adjusted, resulting in poor flexibility. It is difficult to precisely control the presser foot's downward pressure on fabrics of varying thicknesses, requiring significant time to adjust the presser foot's height, thus impacting production efficiency.

[0036] To further understand the content, features, and effects of this application, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0037] Example 1:

[0038] Reference Figures 1-3 , Figure 1 This is a schematic diagram of the semi-independent motor press head in Example 1. Figure 2 This is another structural schematic diagram of the semi-independent motor presser head in Embodiment 1. Figure 3 This is a schematic diagram of the internal structure of the semi-independent motor presser foot head in Embodiment 1. The semi-independent motor presser foot head in this embodiment includes a frame 1, an embroidery mechanism 2, a drive mechanism 3, and an adjustment mechanism 4. The embroidery mechanism 2 includes a frame 21 and multiple embroidery units arranged side by side on the frame 21. The frame 21 is movably mounted on the frame 1. Each embroidery unit includes an embroidery needle 22, a presser foot 23, and a thread take-up piece 24. The embroidery needle 22 is movably mounted on the frame 21, the presser foot 23 is movably mounted on the frame 21 and close to one end of the embroidery needle 22, and the thread take-up piece 24 is mounted on the frame 21 and close to the other end of the embroidery needle 22. The driving mechanism 3 includes a driving component 31, a driving shaft 32, a needle transmission component 33, a presser foot transmission component 34, a thread take-up transmission component 35, and a sliding column 36. The driving shaft 32 is connected to the driving end of the driving component 31. One end of the needle transmission component 33 and one end of the presser foot transmission component 34 are respectively connected to the driving shaft 32. The other ends of the needle transmission component 33 and the presser foot transmission component 34 are slidably connected to the sliding column 36 and respectively connected to the needle component 22 and the presser foot component 23 of the same embroidery unit. The two ends of the thread take-up transmission component 35 are respectively connected to the needle transmission component 33 and the thread take-up component 24. The adjustment mechanism 4 includes an adjustment driving component 41 and an adjustment transmission component 42. One end of the adjustment transmission component 42 is connected to the adjustment driving component 41, and the other end of the adjustment transmission component 42 is connected to the presser foot transmission component 34. The adjustment driving component 41 drives the adjustment transmission component 42 to swing, and the swing of the adjustment transmission component 42 causes the other end of the presser foot transmission component 34 to move on the sliding column 36.

[0039] In this embodiment, the semi-independent motor presser foot head is used for embroidery on fabric. During embroidery, the drive unit 31 drives the drive shaft 32 to rotate. The rotation of the drive shaft 32 synchronously drives the embroidery needle transmission unit 33 and the presser foot transmission unit 34 to move, thereby driving the embroidery needle 22 and the presser foot 23 to move back and forth on the sliding column 36 to perform embroidery. That is, the presser foot 23 descends to press the fabric firmly, ensuring that the fabric is stable and does not shake. The embroidery needle 22 rises and falls to perform embroidery. After one embroidery is completed, the presser foot 23 rises to release the fabric, making it easier to move the fabric to perform the next stitch. This process is repeated. In this embodiment, the driving force for the embroidery needle 22 and the presser foot 23 to move back and forth comes from the drive unit 31 and the drive shaft 32. That is, the embroidery needle 22 and the presser foot 23 are driven by the same driving source, ensuring the synchronicity of the actions of the embroidery needle 22 and the presser foot 23. When dealing with fabrics of different thicknesses, by adjusting the settings of the drive component 41 and the transmission component 42, the drive component 41 drives the transmission component 42 to swing, and the swing of the transmission component 42 causes the other end of the presser foot transmission component 34 to move on the sliding column component 36. In this way, the other end of the presser foot transmission component 34 and the position of the presser foot 23 can be adjusted separately, thereby adjusting the initial height of the presser foot 23 to automatically adapt to fabrics of different thicknesses, saving the time of manually adjusting the height of the presser foot and improving production efficiency.

[0040] Reference Figure 4 and Figure 5 , Figure 4 This is a schematic diagram of the embroidery needle drive and thread take-up drive in Example 1. Figure 5The diagram below illustrates the structure of the embroidery unit in Embodiment 1. Preferably, the needle transmission component 33 includes a needle transmission cam 331, a needle transmission connecting rod 332, and a needle transmission block 333. The needle transmission cam 331 is sleeved on the drive shaft 32. The two ends of the needle transmission connecting rod 332 are rotatably connected to the needle transmission cam 331 and the needle transmission block 333, respectively. The needle transmission block 333 is slidably connected to the slide column 36. In practical application, the drive component 31 drives the drive shaft 32 to rotate. The rotation of the drive shaft 32 causes the needle transmission cam 331 to rotate. The rotation of the needle transmission cam 331 causes the needle transmission connecting rod 332 to swing. The swing of the needle transmission connecting rod 332 causes the needle transmission block 333 to move back and forth on the slide column 36, thereby driving the needle component 22 to move back and forth to perform embroidery operations. Specifically, the needle drive cam 331 is a needle drive cam. In this embodiment, there are three needle drive linkages 332, which are connected end to end. The first linkage 332 is rotatably connected to the needle drive cam, and the last linkage 332 is connected to the needle drive block 333. Of course, in other embodiments, the number of needle drive linkages 332 can be two or more, which can be set according to the needs to meet the different precision requirements of the movement of the needle drive block 333. Specifically, the drive shaft 32 is a drive shaft, and the drive component 31 includes a drive motor, a drive wheel, and a drive belt. The drive motor is connected to the drive wheel, and the drive belt is wound around the drive wheel and the drive shaft in sequence. Of course, in other embodiments, other drive methods can be used, which are not limited here. The sliding column 36 is a sliding column.

[0041] Rereference Figure 4 and Figure 5Preferably, the needle drive block 333 has a second notch 3331 at one end facing the embroidery unit, and the needle component 22 has a second protrusion 221 corresponding to the second notch 3331. The second protrusion 221 is embedded in or away from the second notch 3331, so that the needle component 22 is connected to or separated from the needle drive block 333. In specific applications, the embroidery mechanism 2 also includes a moving component 25, which is located on the frame 1. The frame component 21 is movably located on the moving component 25. The moving component 25 includes a slide rail 251, a slider 252, and a moving drive body (not shown in the figure). The slide rail 251 is located on the frame 1, the slider 252 is slidably located on the slide rail 251, the driving end of the moving drive body is connected to the slider 252, and the frame component 21 is located on the slider 252. The moving drive body drives the slider 252 to slide on the slide rail 251, thereby driving the frame component 21 to move on the slide rail 251. In this embodiment, the moving drive is a linear motor. Of course, in other embodiments, the moving drive can also be driven by a motor through a lead screw pair to slide the slider 252, or the motor can be driven by a belt to slide the slider 252. It is not limited here. It can be understood that the moving part 25 drives the frame part 21 to move, so that one of the embroidery needle parts 22 is directly opposite the embroidery needle transmission block 333 of the embroidery needle transmission part 33. That is, the second protrusion 221 of one of the embroidery needle parts 22 is embedded in the second notch 3331. At this time, the driving part 31 drives the driving shaft part 32 to rotate. The rotation of the driving shaft part 32 drives the embroidery needle transmission cam part 331 to rotate. The rotation of the embroidery needle transmission cam part 331 drives the embroidery needle transmission link 332 to swing. The swing of the embroidery needle transmission link 332 drives the embroidery needle transmission block 333 to move up and down on the sliding column part 36. The up and down movement of the embroidery needle transmission block 333 drives the embroidery needle part 22 to move up and down to perform embroidery operations. Understandably, when it is necessary to switch between different colors or types of embroidery threads for embroidery, the moving part 25 drives the frame part 21 to move, causing another embroidery needle part 22 to be directly aligned with the embroidery needle transmission block 333 of the embroidery needle transmission part 33. At this time, the second protrusion 221 of the other embroidery needle part 22 is inserted into the second notch 3331, that is, the other embroidery needle part 22 is engaged with the embroidery needle transmission block 333, and the embroidery needle transmission block 333 can then drive the other embroidery needle part 22 to reciprocate up and down for embroidery operations. Specifically, the arrangement direction of the multiple embroidery units on the embroidery mechanism 2 is the axial direction of the driving shaft part 32, and the movement direction of the frame part 21 on the slide rail 251 is also the axial direction of the driving shaft part 32.

[0042] Reference Figure 6 and Figure 7 , Figure 6 This is a schematic diagram of the presser foot transmission component in Example 1. Figure 7The diagram below shows the structure of the sliding column, needle transmission block, and presser foot transmission block in Embodiment 1. Preferably, the presser foot transmission component 34 includes a presser foot transmission cam 341, a presser foot transmission connecting rod 342, and a presser foot transmission block 343. The presser foot transmission cam 341 is sleeved on the drive shaft 32. The two ends of the presser foot transmission connecting rod 342 are rotatably connected to the presser foot transmission cam 341 and the presser foot transmission block 343, respectively. The presser foot transmission block 343 is slidably connected to the sliding column 36. The other end of the presser foot transmission connecting rod 342 is hinged to the adjusting transmission component 42. In practical applications, the driving component 31 drives the driving shaft 32 to rotate. The rotation of the driving shaft 32 causes the presser foot transmission cam 341 to rotate. The rotation of the presser foot transmission cam 341 causes the presser foot transmission connecting rod 342 to swing. The swing of the presser foot transmission connecting rod 342 causes the presser foot transmission block 343 to move back and forth on the sliding column 36. The reciprocating up and down movement of the presser foot transmission block 343 causes the presser foot 23 to move back and forth to press or loosen the fabric. Specifically, the presser foot transmission cam 341 is a presser foot transmission cam. In this embodiment, there are three presser foot transmission connecting rods 342. The three presser foot transmission connecting rods 342 are connected end to end. The first presser foot transmission connecting rod 342 is rotatably connected to the presser foot transmission cam, and the last presser foot transmission connecting rod 342 is connected to the presser foot transmission block 343. Of course, in other embodiments, the number of presser foot transmission connecting rods 342 can also be two or more. The specific setting can be set according to the needs to meet the different accuracy requirements of the movement of the presser foot transmission block 343. Eccentric pin 424 is connected to the connection point of two of the presser foot drive linkages 342.

[0043] Rereference Figure 6 and Figure 7Preferably, the presser foot transmission block 343 has a first notch 343 at one end facing the embroidery unit, and the presser foot 23 has a first protrusion 231 at the position corresponding to the first notch 343. The first protrusion 231 is embedded in or away from the first notch 343, so that the presser foot 23 is connected or separated from the presser foot transmission block 343. In practical application, the moving part 25 drives the frame part 21 to move, so that one of the presser foot parts 23 is directly opposite the presser foot transmission block 343 of the presser foot transmission part 34. That is, the first protrusion 231 of one of the presser foot parts 23 is embedded in the first notch 3431. At this time, the driving part 31 drives the driving shaft part 32 to rotate. The rotation of the driving shaft part 32 drives the presser foot transmission cam part 341 to rotate. The rotation of the presser foot transmission cam part 341 drives the presser foot transmission link 342 to swing. The swinging of the presser foot transmission link 342 drives the presser foot transmission block 343 to move up and down on the sliding column part 36. The reciprocating up and down movement of the presser foot transmission block 343 drives the presser foot part 23 to move up and down to press or loosen the fabric. Understandably, when it is necessary to switch between different colors or types of embroidery threads for embroidery, the moving part 25 drives the frame part 21 to move, causing the other presser foot part 23 to face the presser foot transmission block 343 of the presser foot transmission part 34. At this time, the first protrusion 231 of the other presser foot part 23 is inserted into the first notch 3431, that is, the other presser foot part 23 is engaged with the presser foot transmission block 343, and the presser foot transmission block 343 can drive the other presser foot part 23 to reciprocate up and down. Specifically, the thread take-up transmission part 35 includes a thread take-up transmission link 351 and a thread take-up transmission block 352. The two ends of the thread take-up transmission link 351 are respectively connected to the thread take-up transmission block 352 and the embroidery needle transmission cam part 331. The thread take-up part 24 has a third notch, and the thread take-up transmission block 352 can be inserted into the third notch so that the thread take-up part 24 is engaged with the thread take-up transmission block 352. By setting the thread take-up transmission linkage 351, this embodiment can simultaneously drive the thread take-up component 24 and the embroidery needle component 22 with only one embroidery needle transmission cam 331, improving the synchronization of the movement of the thread take-up component 24 and the embroidery needle component 22 and simplifying the equipment structure. Of course, in other embodiments, an additional thread take-up transmission cam can also be set, which is not limited here. The way in which the thread take-up component 24 is engaged with the thread take-up transmission block 352 is similar to the way in which the embroidery needle component 22 is engaged with the embroidery needle transmission block 333. That is to say, the embroidery needle component 22, the presser foot component 23 and the thread take-up component 24 of the same embroidery unit are all located on the same vertical line. When it is necessary to switch to different colors or types of embroidery thread, the frame component 21 drives multiple embroidery units to move and make one of the embroidery units face the drive mechanism 3. That is, the second protrusion 221 of the embroidery needle component 22, the first protrusion 231 of the presser foot component 23 and the thread take-up transmission block 352 in the embroidery unit are respectively embedded in the second notch 3331, the first notch 3431 and the third notch. Specifically, the thread take-up component 24 is the thread take-up lever of the embroidery machine, used for feeding and taking back the embroidery thread and working in conjunction with the embroidery needle component 22 for embroidery. The embroidery needle component 22 is the embroidery needle module of the embroidery machine, the presser foot component 23 is the presser foot module of the embroidery machine, and the frame component 21 is the support frame.

[0044] Reference Figure 8 and Figure 9 , Figure 8 This is a schematic diagram of the structure of the adjusting transmission component in Embodiment 1. Figure 9 The diagram below illustrates the structure of the eccentric pin in Embodiment 1. Preferably, the adjusting drive component 41 includes an adjusting drive body 411 and an adjusting shaft 412. The adjusting shaft 412 is connected to the drive end of the adjusting drive body 411, and one end of the adjusting transmission component 42 is connected to the adjusting shaft 412. In specific applications, the adjusting drive body 411 includes an adjusting drive motor, a first adjusting transmission wheel, a second adjusting transmission wheel, and an adjusting transmission belt. The drive end of the adjusting drive motor is connected to the first adjusting transmission wheel, and the second adjusting transmission wheel is connected to the adjusting shaft 412. The adjusting transmission belt is sequentially wound around the first and second adjusting transmission wheels, and the radius of the first adjusting transmission wheel is smaller than the radius of the second adjusting transmission wheel, thus achieving speed reduction transmission. Specifically, the adjusting shaft 412 and the drive shaft component 32 are arranged parallel to each other.

[0045] Rereference Figure 8Preferably, the adjusting transmission component 42 includes a first adjusting swing block 421, an adjusting connecting rod 422, a second adjusting swing block 423, and an eccentric pin 424. One end of the first adjusting swing block 421 is sleeved outside the adjusting shaft 412, and the other end of the first adjusting swing block 421 is hinged to one end of the adjusting connecting rod 422. The other end of the adjusting connecting rod 422 is hinged to one end of the second adjusting swing block 423. The other end of the second adjusting swing block 423 is connected to one end of the eccentric pin 424, and the other end of the eccentric pin 424 is hinged to the pressure foot transmission component 34. In practical application, the adjusting drive body 411 drives the adjusting shaft 412 to rotate. The rotation of the adjusting shaft 412 causes the first adjusting swing block 421 to swing. The swing of the first adjusting swing block 421 causes the adjusting connecting rod 422 to swing. The swing of the adjusting connecting rod 422 causes the second adjusting swing block 423 to swing. The swing of the second adjusting swing block 423 causes the eccentric pin 424 to swing eccentrically. The eccentric pin 424 swings eccentrically, causing the presser foot transmission block 343 to move back and forth up and down on the sliding column 36. It can be understood that when the embroidery mechanism 2 is performing normal embroidery operations, the adjusting drive body 41 does not work. When switching between fabrics of different thicknesses for embroidery, the adjusting drive component 41 drives the adjusting transmission component 42 to move the presser foot transmission component 34, thereby causing the presser foot component 23 to rise and fall. This adjusts the initial height of the presser foot component 23 to automatically adapt to fabrics of different thicknesses, saving time spent manually adjusting the presser foot height and improving production efficiency. Moreover, when it is necessary to switch between different colors or types of embroidery threads, the height of the presser foot transmission block 343 can be adjusted to make it move to the same height as the first protrusion 231 on the presser foot component 23. This ensures that the first protrusion 231 and the first notch 3431 are at the same height, allowing the first protrusion 231 to better fit into the first notch 3431, thus connecting the presser foot transmission block 343 and the presser foot component 23.

[0046] Rereference Figures 1-3 Preferably, there are multiple embroidery mechanisms 2, needle drive components 33, presser foot drive components 34, thread take-up drive components 35, sliding column components 36, and adjusting drive components 42. These multiple embroidery mechanisms 2 are spaced apart along the axial direction of the drive shaft 32. Each embroidery mechanism 2 is paired with one needle drive component 33, one presser foot drive component 34, one thread take-up drive component 35, one sliding column component 36, and one adjusting drive component 42. In practical applications, this embodiment uses only one drive component 31 as the drive source. Through the transmission of the drive shaft 32, multiple needle drive components 33, multiple presser foot drive components 34, and multiple thread take-up drive components 35 are driven simultaneously. This allows multiple embroidery mechanisms 2 to perform embroidery operations simultaneously, further simplifying the equipment structure and enabling multiple embroidery mechanisms 2 to perform embroidery operations at the same time, thus improving production efficiency.

[0047] Reference Figure 10 , Figure 10The diagram below illustrates the structure of the clutch mechanism in Embodiment 1. Preferably, the semi-independent motor presser head further includes a clutch mechanism 5. The needle drive block 333 is rotatably mounted on the sliding column 36. The drive end of the clutch mechanism 5 abuts against the needle drive block 333. The clutch mechanism 5 pushes the needle drive block 333 to rotate on the sliding column 36, causing the second notch 3331 to be offset from or directly opposite the second protrusion 221. In specific applications, there are multiple clutch mechanisms 5, with one clutch mechanism 5 provided on the side of each needle drive block 333. With the clutch mechanism 5 in place, since all the embroidery mechanisms 2 in this embodiment are driven by a single drive source, when the embroidery unit on one of the embroidery mechanisms 2 is not required to perform embroidery work, the clutch mechanism 5 can push the needle transmission block 333 to rotate on the sliding column 36 so that the second notch 3331 and the second protrusion 221 are misaligned. This prevents the second protrusion 221 of the needle part 22 of the embroidery unit on the embroidery mechanism 2 from being aligned with and embedded in the second notch 3331 of the needle transmission block 333. Thus, when the needle transmission block 333 moves up and down on the sliding column 36, it will not drive the needle part 22 to move synchronously. In other words, the embroidery unit on the embroidery mechanism 2 is not performing embroidery work at this time. This allows for the corresponding adjustment of the embroidery mechanism 2 that needs to work, thus broadening the application scenarios.

[0048] Rereference Figure 10Preferably, the clutch mechanism 5 includes a clutch drive member 51, a clutch drive swing arm 52, a clutch drive connecting rod 53, and two clutch push blocks 54. The drive end of the clutch drive member 51 is connected to one end of the clutch drive swing arm 52, and the other end of the clutch drive swing arm 52 is connected to the clutch drive connecting rod 53. The two ends of the clutch drive connecting rod 53 are respectively connected to the two clutch push blocks 54, and the two clutch push blocks 54 abut against the embroidery needle transmission block 333 and the presser foot transmission member 34 respectively. In practical applications, the embroidery needle transmission block 333 includes a sliding block 3332, a torsion spring 3333, and a driving block 3334. The sliding block 3332 is slidably sleeved on the outside of the sliding column 36 and is connected to the embroidery needle transmission connecting rod 332. The sliding block 3332 has a receiving groove. The torsion spring 3333 is sleeved on the outside of the sliding column 36 and is connected to the receiving groove of the sliding block 3332. The driving block 3334 is sleeved on the outside of the torsion spring 3333. The second notch 3331 is opened on the side of the driving block 3334 facing the embroidery needle 22. The side of the driving block 3334 near the clutch push block 54 has a sliding rod. One end of the clutch push block 54 has a rotating bearing. The rotating bearing and the sliding rod can slide relative to each other. Understandably, when the embroidery mechanism 2 is performing normal embroidery work, the clutch push block 54 moves away from the needle transmission block 333. Under the action of the torsion spring 3333, the second notch 3331 on the drive block 3334 is directly opposite to the second protrusion 221. That is, the second protrusion 221 can be embedded in the second notch 3331 to realize the connection between the needle transmission block 333 and the needle component 22. When it is necessary to stop the operation of a certain embroidery mechanism 2 without affecting the normal operation of the other embroidery mechanisms 2, the clutch drive member 51 drives the clutch drive swing arm 52 to swing. The swing of the clutch drive swing arm 52 drives the clutch drive linkage 53 to swing. The swing of the clutch drive linkage 53 drives one of the clutch push blocks 54 to abut against and push the drive block 3334 to overcome the torque of the torsion spring 3333 and rotate relative to the sliding column member 36, so that the second notch 3331 is misaligned with the second protrusion 221, that is, the second protrusion 221 cannot be inserted into the second notch 3331, that is, the embroidery needle transmission block 333 and the embroidery needle member 22 cannot be connected. At this time, the drive member 31 drives the drive shaft member 32 to drive the second notch 3331. When the needle drive component 33 moves up and down on the sliding column component 36, it does not drive the needle component 22 to move up and down, thus preventing the needle component 22 from performing embroidery operations. The rotating bearing reduces friction between the clutch push block 54 and the sliding column, preventing wear. When the embroidery mechanism 2 needs to resume embroidery operations, the clutch drive component 51 drives the clutch drive arm 52 to swing. The swing of the clutch drive arm 52 drives the clutch drive linkage 53 to swing, which in turn drives one of the clutch push blocks 54 away from the drive block 3334. The drive block 3334 then returns to its original position under the torque of the torsion spring 3333. Specifically, the structure of the presser foot drive block 343 is similar to that of the needle drive block 333, and their clutch engagement and disengagement methods are also similar, so they will not be described further here.The clutch drive component 51 is a clutch drive motor.

[0049] Example 2:

[0050] Reference Figure 11 and Figure 12 , Figure 11 This is a schematic diagram of the presser foot transmission component in Example 2. Figure 12 for Figure 11 The enlarged view of section A shows that the semi-independent motor presser head in this embodiment differs from that in Embodiment 1 in that there are two adjusting rods 422. One end of one adjusting rod 422 is hinged to the other end of the first adjusting swing block 421, the other end of one adjusting rod 422 is hinged to one end of the other adjusting rod 422, and the other end of the other adjusting rod 422 is hinged to one end of the second adjusting swing block 423. In practical application, the two adjusting rods 422 are connected by a rotating wheel. By using two adjusting rods 422, the transmission distance of the adjusting transmission component 42 is increased. It is understood that in one embodiment, the adjusting drive component 41 needs to be positioned relatively close to the presser foot transmission component 34, i.e., in the middle of the frame component 21. However, by using two adjusting rods 422, the adjusting drive component 41 can be positioned further away from the presser foot transmission component 34, for example, above the frame component 21. This frees up the middle of the frame component 21 for other mechanisms, improving space utilization. Furthermore, the middle of the frame component 21 is no longer obstructed by the adjusting drive component 41, facilitating maintenance of the embroidery mechanism 2. Of course, in other embodiments, the number of adjusting rods 422 can be three or more, depending on the specific requirements to meet different precision requirements for the movement of the adjusting transmission component 42; this is not limited here.

[0051] Example 3:

[0052] Reference Figure 13 and Figure 14 , Figure 13 This is a schematic diagram of the presser foot transmission component in Example 3. Figure 14 for Figure 13The enlarged view of section B shows that the semi-independent motor presser head in this embodiment differs from that in Embodiment 1 in that the adjusting transmission component 42 in this embodiment includes an eccentric pin 424, an adjusting transmission cable 425, and two adjusting transmission wheels 426. One adjusting transmission wheel 426 is sleeved on the adjusting shaft 412, and the other adjusting transmission wheel 426 is sleeved on the eccentric pin 424. The adjusting transmission cable 425 is sequentially wound around the two adjusting transmission wheels 426. The eccentric pin 424 is hinged to the presser foot transmission component 34. In practical applications, this embodiment achieves transmission through the adjusting transmission wheels 426 and the adjusting transmission cable 425. Compared with linkage transmission, the transmission debugging process in this embodiment is simpler, improving the stability of the transmission. Moreover, the setting of the adjusting transmission cable 425 also makes it easy to set the adjusting drive component 41 away from the presser foot transmission component 34. It is only necessary to set guide wheels between the adjusting transmission cables 425 to ensure that the tension of the adjusting transmission cable 425 is appropriate and to provide guidance. Of course, in other embodiments, the adjusting transmission cable 425 can also be replaced by a belt, steel cable, etc., which is not limited here.

[0053] In summary, in this embodiment, the driving force for the reciprocating up-and-down movement of the embroidery needle 22 and the presser foot 23 both originates from the drive component 31 and the drive shaft 32. That is, the embroidery needle 22 and the presser foot 23 are driven by the same drive source, ensuring the synchronicity of the movements of the embroidery needle 22 and the presser foot 23. When dealing with fabrics of different thicknesses, by adjusting the settings of the driving component 41 and the adjusting transmission component 42, the driving component 41 drives the adjusting transmission component 42 to swing. The swinging of the adjusting transmission component 42 causes the other end of the presser foot transmission component 34 to move on the sliding column component 36. In this way, the other end of the presser foot transmission component 34 and the position of the presser foot 23 can be adjusted separately, thereby adjusting the initial height of the presser foot 23 to automatically adapt to fabrics of different thicknesses, saving the time of manually adjusting the height of the presser foot and improving production efficiency. Moreover, when it is necessary to switch to different colors or types of embroidery threads, by adjusting the height of the presser foot transmission block 343, it can be moved to the same height as the first protrusion 231 on the presser foot 23. That is, the first protrusion 231 and the first notch 3431 are at the same height, so that the first protrusion 231 can be better embedded in the first notch 3431 to realize the connection between the presser foot transmission block 343 and the presser foot 23.

Various modifications and variations can be made to this application by those skilled in the art.
