Description

Technical Field

[0001] The invention belongs to the technical field of embroidery equipment, and in particular relates to a coiling embroidery machine. Background Art

[0002] Referring to a prior art tape embroidery machine, it includes a transversely extending mounting beam and several tape embroidery heads mounted on the mounting beam. To enable flat embroidery, flat embroidery heads can also be spaced apart between the tape embroidery heads. The tape embroidery heads include a head housing, which is equipped with a needle bar driver to drive the needle bar. The tape embroidery heads and flat embroidery heads operate alternately. When the tape embroidery head is operating, the thread take-up lever assembly on it is required to take up the thread. When the flat embroidery head is operating and the tape embroidery head is not operating, the thread take-up lever assembly is separated from the thread take-up lever driver. In this case, the thread take-up lever assembly needs to be locked, and once locked, the thread take-up lever assembly cannot rotate. In the prior art, the thread take-up lever assembly is provided with a locking slot, with a locking member fixed relative to the locking slot. When the thread take-up lever assembly is not operating, the locking member is inserted into the locking slot, locking the thread take-up lever assembly. When the thread take-up lever assembly is operating, the locking member is disengaged from the locking slot, and the thread take-up lever assembly aligns with the driving portion of the thread take-up lever driver, allowing it to rotate to take up the thread.

[0003] Therefore, in the prior art, a thread take-up clutch mechanism for tape embroidery is provided, which is used to drive the thread take-up lever assembly to move laterally, so as to realize the engagement and separation of the thread take-up lever assembly and the thread take-up lever driver, and at the same time realize the engagement and separation of the thread take-up lever assembly and the locking member. However, the thread take-up clutch mechanism of the prior art is provided on each tape embroidery machine head. The thread take-up clutch mechanism provided separately on each tape embroidery machine head requires a clutch driving component to drive the thread take-up lever assembly to engage and disengage, which results in an increase in the number of components of the tape embroidery machine head. Summary of the Invention

[0004] In view of the deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a tape embroidery thread picking clutch mechanism and a tape embroidery machine. It is not necessary to set a clutch drive component for each tape embroidery machine head, and multiple tape embroidery machine heads can share the clutch drive component.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] First, a tape embroidery thread take-up clutch mechanism is provided, which is used to drive the thread take-up rod assembly on at least two tape embroidery machine heads to move laterally. The thread take-up clutch mechanism includes a clutch driving component, a clutch pull rod and a thread take-up connecting rod component correspondingly arranged on each tape embroidery machine head. The clutch pull rod is connected to the thread take-up connecting rod components on at least two tape embroidery machine heads. The clutch driving component drives the clutch pull rod to move laterally. The thread take-up connecting rod component is driven by the clutch pull rod and drives the thread take-up rod assembly to move laterally.

[0007] Preferably, the thread taking-up link component includes a vertically extending link shaft, a first link vertically connected to the lower end of the link shaft, and a second link vertically connected to the upper end of the link shaft, and there is an angle between the horizontal projections of the first link and the second link.

[0008] Preferably, the clutch driving component includes a clutch connecting rod and a clutch motor, the clutch connecting rod is connected to the clutch pull rod, the clutch motor drives the clutch connecting rod to swing, and the clutch connecting rod drives the clutch pull rod to move laterally.

[0009] Preferably, the middle portion of the clutch connecting rod is connected to the connecting rod pin, the first end of the clutch connecting rod is connected to the clutch motor, and the second end is connected to the clutch pull rod.

[0010] Preferably, the first end of the clutch connecting rod is provided with a first elongated slot, the motor shaft of the clutch motor is connected to the clutch wheel, the eccentric part of the clutch wheel is provided with a first pin, and the first pin is connected to the first elongated slot; and / or, the second end of the clutch connecting rod is provided with a second elongated slot, one end of the pull rod is connected to the second pin, and the second pin is connected to the second elongated slot.

[0011] Preferably, the thread take-up lever assembly is connected to a clutch slider, the clutch slider is slidably matched with a clutch slide rail, and the clutch slider is connected to a thread take-up connecting rod component.

[0012] Preferably, the clutch slider is provided with an elongated driving slot, and the thread take-up link component is provided with a driving pin, and the driving pin is connected to the driving slot.

[0013] Preferably, the thread take-up lever assembly is rotatably mounted on the thread take-up shaft, and the clutch slider is provided with a clutch guide hole, and the clutch guide hole is slidably fitted with the thread take-up shaft.

[0014] Preferably, a U-shaped groove is provided at the rear of the clutch slider, and the connection part between the thread take-up rod assembly and the thread take-up shaft is provided in the U-shaped groove; and / or a clutch guide groove is provided at the front of the clutch slider, the clutch slide rail includes a clutch guide rod, and the clutch guide groove cooperates with the clutch guide rod.

[0015] Secondly, a coiling embroidery machine is provided, comprising the coiling embroidery thread take-up clutch mechanism.

[0016] The technical solution adopted by the present invention has the following beneficial effects:

[0017] Since multiple tape embroidery machine heads can share a clutch drive component and a clutch pull rod, the thread take-up lever assemblies on at least two tape embroidery machine heads share a common drive source. That is, one clutch drive component drives one clutch pull rod to move laterally, and one clutch pull rod drives the thread take-up connecting rod assemblies on at least two tape embroidery machine heads. Therefore, it is not necessary to provide a drive source on each tape embroidery machine head to drive the thread take-up lever assembly to move laterally. Only a thread take-up connecting rod component needs to be provided on the tape embroidery machine head to drive the thread take-up rod assembly, which not only reduces the number of components provided on the tape embroidery machine head corresponding to the tape embroidery thread take-up clutch mechanism, but also reduces the number of components provided on the entire tape embroidery machine corresponding to the tape embroidery thread take-up clutch mechanism, thereby reducing costs. Moreover, the thread take-up connecting rod component is relatively provided with a separate driving source on the tape embroidery machine head (usually a cylinder, which is provided on the lateral side of the thread take-up rod assembly. Even if the cylinder is small, it will occupy the lateral space of the machine head. In addition, the telescopic space reserved for the cylinder push rod occupies a large lateral space of the machine head), which can reduce the width space occupied, thereby reducing the width of the tape embroidery machine head, which is conducive to installing more machine heads on the mounting beam.

[0018] These features and advantages of the present invention will be disclosed in detail in the following specific embodiments and drawings. BRIEF DESCRIPTION OF THE DRAWINGS

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0040] Referring to a conventional tape embroidery machine, it comprises a transversely extending mounting beam and several tape embroidery heads mounted side by side on the mounting beam. The tape embroidery heads comprise a head housing and a tape embroidery head assembly mounted thereto, which includes a needle bar driver. To achieve flat embroidery, flat embroidery heads can be spaced apart between the tape embroidery heads. The flat embroidery heads also comprise a head housing and a flat embroidery head assembly mounted thereto, which includes a needle bar driver. That is, the tape embroidery heads are spaced apart along the transverse extension of the mounting beam, allowing for separate operations for tape embroidery and flat embroidery, as needed.

[0041] In this embodiment, the extending direction of the mounting beam is defined as the transverse direction, and the direction perpendicular to the beam is defined as the front-rear direction. The tape embroidery machine is provided with a main shaft extending in the transverse direction and passing through each machine head housing, and the main shaft serves as a power source for driving the needle bar driver.

[0042] In the tape embroidery machine head, the needle bar driver drives the needle bar to perform reciprocating lifting and lowering motions, allowing the embroidery needle at the bottom of the needle bar to embroider the material tape onto the fabric. In addition, the machine head housing is provided with a thread take-up lever assembly and a corresponding thread take-up lever driver. The thread take-up lever assembly is provided in correspondence with the needle bar. During the needle bar operation, the thread take-up lever driver is used to drive the thread take-up lever assembly to take up the thread.

[0043] In addition, the head assembly of the tape embroidery machine also includes a tape reel assembly, which includes a tape reel bracket, on which a tape reel is rotatably mounted, and on which a tape roll is stored. The tape reel assembly is mounted on the M-axis assembly. During the tape embroidery process, the tape is drawn from the reel and fed to the presser foot. Typically, at least two tape reel brackets are installed. For example, if two tape reel brackets are provided, they are symmetrically arranged on the left and right sides of the M-axis assembly.

[0044] Reference Figures 1 to 10 As shown, this embodiment provides a tape embroidery machine, comprising an M-axis assembly 1, an M-axis driving structure 2, and a tape reel component 6 connected to the M-axis assembly 1. The M-axis assembly 1 comprises an M-axis sleeve 11, a presser foot sleeve 12 nested in the M-axis sleeve, a ball bearing 122 provided between the M-axis sleeve 11 and the presser foot sleeve 12, and a presser foot shaft 13 movably nested in the presser foot sleeve. The presser foot shaft 13 is a hollow structure, and an independent needle bar 14 is movably nested inside. The presser foot sleeve 12 is fixed to the machine head housing, the M-axis sleeve 11 and the presser foot shaft 13 can move relative to the presser foot sleeve 12, and the independent needle bar 14 can move relative to the presser foot shaft 13. The M-axis driving structure 2 comprises an M-axis driving component for driving the M-axis sleeve 11 to rotate, a presser foot sleeve driving component 3 for driving the presser foot sleeve to rotate and driving the presser foot shaft to rotate, and a presser foot lifting component 4 for driving the presser foot shaft to rise and fall. A presser foot 131 is mounted at the bottom of the presser foot shaft, and an embroidery needle 141 is mounted at the bottom of the independent needle bar.

[0045] Compared to the existing technology, which uses a fixed sleeve, this embodiment employs a nested structure consisting of an M-axis sleeve, presser foot sleeve, presser foot shaft, and needle bar, but without a fixed sleeve. Instead, the presser foot sleeve is secured to the machine head housing. Reducing the fixed sleeve helps simplify the M-axis assembly structure, thereby reducing its overall diameter and saving space. This in turn reduces the width of the tape embroidery machine head, facilitating the installation of more heads on the mounting beam.

[0046] To ensure coaxiality between the M-shaft sleeve and the presser foot sleeve, as well as to ensure flexible rotation between them, a bearing can be installed between the M-shaft sleeve and the presser foot sleeve. However, installing a bearing increases the distance between the M-shaft sleeve and the presser foot sleeve, increasing the overall diameter of the M-shaft assembly and negating the effect of reducing the fixed sleeve. Therefore, this embodiment employs a ball bearing between the M-shaft sleeve and the presser foot sleeve, eliminating the need for a separate bearing. Compared to installing a bearing, this provides a more compact structure and reduces the overall diameter of the M-shaft assembly.

[0047] like Figures 2 to 4 As shown, the upper outer circumference of the presser foot sleeve and the upper inner circumference of the M sleeve are correspondingly provided with a first ball positioning step 111, and the first ball positioning step is provided with a raceway that cooperates with ball 122. A limiting sleeve 123 is fixed to the lower side of the M sleeve. The lower inner circumference of the M sleeve and the upper outer circumference of the limiting sleeve are correspondingly provided with a second ball positioning step 112, and the second ball positioning step is provided with a raceway that cooperates with ball 122. In this way, the raceway can be directly machined onto the presser foot sleeve, M sleeve, and limiting sleeve, with machining accuracy comparable to that of a bearing. This produces a similar effect to installing a bearing, but with a much simpler structure, fewer parts, and lower costs.

[0048] Furthermore, to secure the M-axis assembly to the machine head housing, the presser foot sleeve 12 is provided with a fixing flange 121 above the M-axis sleeve 11. This fixing flange 121 is secured to the machine head housing of the tape embroidery machine head. Furthermore, the fixing flange is provided with a rocker rod through hole 1211, through which the rocker rod 54 passes, allowing it to move up and down. To connect the presser foot shaft 13 to the presser foot lift assembly 4, a presser foot lift seat 133 is connected to the upper end of the presser foot shaft 13.

[0049] like Figure 5 As shown, the M-axis driving component includes an M-axis driving motor 21 for driving the M-axis to rotate. The axial direction of the M-axis driving motor is parallel to the axial direction of the M-axis sleeve. A first transmission belt assembly 22 is provided between the motor shaft of the M-axis driving motor and the M-axis sleeve 11. The presser foot sleeve driving component 3 includes a presser foot sleeve driving motor 31 for driving the presser foot sleeve to rotate. The axial direction of the presser foot sleeve driving motor is parallel to the axial direction of the presser foot sleeve. A second transmission belt assembly 32 is provided between the motor shaft of the presser foot sleeve driving motor and the presser foot sleeve 12.

[0050] The M-axis drive motor 21 and the presser foot cover drive motor 31 are both located on a first lateral side of the M-axis assembly, and the M-axis drive motor 21 is located above the presser foot cover drive motor 31, but the first transmission belt assembly 22 is located below the second transmission belt assembly 32. The motor shaft of the presser foot cover drive motor 31 can be directly connected to the pulley of the second transmission belt assembly, while the motor shaft of the M-axis drive motor 21 can be connected to an extended drive shaft via a coupling, and the extended drive shaft is connected to the pulley of the first transmission belt assembly.

[0051] like Figure 6 As shown, the second transmission belt assembly 32 includes a second transmission pulley 17 mounted on the presser foot sleeve 12 via a needle bearing 124. Furthermore, the presser foot shaft 13 is provided with a keyway 132, and the second transmission pulley 17 is provided with a transmission key 171 that engages with the keyway. Therefore, through the engagement of the transmission key 171 with the keyway 132, the second transmission pulley 17 can drive the presser foot shaft 13 to rotate, while the presser foot shaft 13 can move up and down relative to the second transmission pulley 17.

[0052] Since the independent needle bar 14 and the presser foot shaft 13 are clearance fits, and the clearance is usually large, the verticality of the needle bar is difficult to ensure. Figure 7 As shown, the M-axis assembly 1 includes an independent needle bar auxiliary shaft 15 arranged parallel to the independent needle bar 14. The independent needle bar 14 is connected to a needle bar guide 134, which is provided with a needle bar guide hole 1341 that mates with the independent needle bar auxiliary shaft 15. This guide ensures the verticality of the independent needle bar during its vertical movement. Specifically, the needle bar guide hole 1341 is U-shaped; the needle bar guide 134 is secured to the independent needle bar 14 via a needle bar clamp 1342. The U-shaped hole is open at one end. First, the needle bar guide hole is engaged with the independent needle bar auxiliary shaft, and then the needle bar guide is secured to the independent needle bar via the needle bar clamp, facilitating installation. The clearance between the longitudinal side walls and the independent needle bar auxiliary shaft is small, ensuring that the independent needle bar can move up and down, thereby cooperating with the presser foot shaft to maintain the verticality of the independent needle bar.

[0053] like Figure 8 and Figure 9As shown, in some embodiments, the presser foot lifting assembly 4 includes a presser foot lifting fork 45 connected to the presser foot shaft 13, a presser foot guide block 44 connected to the presser foot lifting fork 45, and a presser foot driving block 43 that drives the presser foot guide block 44 up and down. The presser foot guide block 44 is provided with a guide hole that movably nests with a rocker 54, and the rocker 54 is driven up and down by the rocker lifting assembly. Prior art typically provides a separate slide bar to mate with the guide hole. As the number of functions and components in the tape embroidery machine head increases, the provision of a slide bar interferes with the layout of other components, limiting the expansion of the tape embroidery machine head's functions. In this embodiment, the provision of a rocker bar can expand the functions of the tape embroidery machine head. The rocker bar is driven up and down by the rocker lifting assembly. A sliding sleeve is connected to the bottom of the rocker bar, which can be connected to a material belt tensioner or other functional components. Furthermore, the presser foot lifting assembly 4 also includes a presser foot lifting motor 41 and a third transmission belt assembly driven by the presser foot lifting motor. The third transmission belt assembly includes a third transmission belt 42, which is connected to the presser foot driving block 43. The presser foot guide block 44 is a sideways U-shaped structure, with its opening facing horizontally. It is equipped with an upper limit portion 441 and a lower limit portion 442. The presser foot drive block 43 is equipped with a drive sleeve 431, which is movably nested outside the rocker arm 54 and positioned between the upper limit portion 441 and the lower limit portion 442. A presser foot spring (not shown) is movably nested within the rocker arm 54, with its bottom end abutting the lower limit portion and its top end abutting the bottom surface of the drive sleeve. Therefore, the drive sleeve slides up and down along the rocker arm, driving the presser foot guide block up and down.

[0054] Furthermore, a linear bearing is provided between the drive sleeve 431 and the rocker arm 54 to achieve relative guidance and linear movement, while also reducing friction between the two. The presser foot lift fork 45 is connected to the fork groove of the presser foot lift seat 133, allowing it to raise and lower the presser foot shaft 13 without affecting its rotation.

[0055] like Figure 10 As shown, the M-axis assembly 1 also includes a sliding sleeve 16 and a web tensioner 161 mounted on the sleeve. The web tensioner 161 is provided with a web slot 162, through which the web is drawn from the web reel and passed. The M-axis drive structure 2 also includes a web slot lifting component 5, which drives the sliding sleeve 16 to slide up and down along the M-axis sleeve 11, thereby raising and lowering the web tensioner and its upper web slot. The web is tightened when the web slot rises and loosened when it descends.

[0056] Specifically, the belt slot lifting component 5 includes a belt slot lifting motor 51 and a fourth transmission belt assembly driven by the belt slot lifting. The fourth transmission belt assembly includes a fourth transmission belt 52, which is connected to a belt slot drive block 53, which is connected to the upper end of the rocker arm. The lower end of the rocker arm is connected to a rocker arm fork 55, which is connected to the fork groove on the sliding sleeve 16.

[0057] The third and fourth transmission belt assemblies have similar structures. For example, the third transmission belt assembly comprises a driving pulley, a driven pulley, and a transmission belt connecting the driving and driven pulleys. The transmission belt includes a vertical motion path, with pulleys positioned above and below the vertical motion path, thereby forming a vertical motion path. The presser foot drive block and the grooved drive block follow the transmission belt along the vertical motion path. A tensioning pulley is also provided to tension the transmission belt. The structures of the third and fourth transmission belt assemblies can be referenced to the prior art.

[0058] In this technical solution, the swing arm not only drives the sliding sleeve up and down along the M-sleeve, but also drives the belt slot up and down. Simultaneously, the swing arm serves as the guide shaft for the presser foot drive block and presser foot guide block. This coaxial design eliminates one shaft, eliminating the separate sliding rod used in existing technologies. This results in a more compact structure and lower costs.

[0059] The tape embroidery machine head and the flat embroidery machine head operate alternately. When the tape embroidery machine head is operating, the thread take-up lever assembly on it is engaged with the thread take-up lever driver. When the flat embroidery machine head is operating, the tape embroidery machine head is inoperative. The thread take-up lever assembly is disengaged from the thread take-up lever driver and needs to be locked, preventing the thread take-up lever assembly from rotating. In the prior art, the thread take-up lever assembly is provided with a locking slot with a locking member fixed relative to the locking slot. When the thread take-up lever assembly is inoperative, the locking member is inserted into the locking slot, locking the thread take-up lever assembly. When the thread take-up lever assembly is inoperative, the locking member is disengaged from the locking slot, and the thread take-up lever assembly engages with the drive unit of the thread take-up lever driver, allowing rotation to take up the thread. In the prior art, each tape embroidery machine head is provided with a clutch component, driven by a pneumatic cylinder, which drives the thread take-up lever assembly to move laterally and engage / disengage, thereby switching the thread take-up lever assembly between an operative position and an inoperative position.

[0060] like Figures 11 to 13 As shown, in some embodiments, the tape embroidery machine is further provided with a tape embroidery thread take-up clutch mechanism 8 for driving the thread take-up rod assembly 81 on at least two tape embroidery machine heads to move laterally. The at least two tape embroidery machine heads herein can be all the tape embroidery machine heads of the tape embroidery machine, and the number thereof is at least two.

[0061] To avoid the need for a thread take-up clutch component on each tape embroidery machine head, which would otherwise increase the number of components in the tape embroidery machine head, the thread take-up clutch mechanism 8 in this embodiment includes a clutch drive component, a clutch pull rod 84, and a thread take-up connecting rod component 83 correspondingly provided on each tape embroidery machine head. The clutch drive component drives the clutch pull rod 84 to move laterally, and the thread take-up connecting rod component 83 is driven by the clutch pull rod 84 to drive the thread take-up rod assembly 81 on at least two tape embroidery machine heads to move laterally.

[0062] In this embodiment, the technical solution employed by the thread take-up clutch mechanism for tape embroidery utilizes a shared drive source for the thread take-up lever assemblies on at least two tape embroidery machine heads. Specifically, each of the two machine heads is driven laterally by a clutch drive component, which in turn drives the thread take-up connecting rod components on at least two of the machine heads. Therefore, there is no need to provide a separate drive source on each machine head to drive the thread take-up lever assembly laterally. Only the thread take-up connecting rod component is required to drive the thread take-up lever assembly on the machine head. This not only reduces the number of components required for the thread take-up clutch mechanism on the machine head, but also reduces the number of components required for the thread take-up clutch mechanism on the entire machine, thus reducing costs and facilitating the synchronized movement of the thread take-up connecting rod components on at least two of the machine heads. Furthermore, the thread take-up connecting rod component, compared to having a separate drive source on each machine head, can reduce the width of the machine head, thereby reducing the width of the machine head and facilitating the installation of more machine heads on the mounting beam.

[0063] Wherein, the thread take-up link component 83 includes a vertically extending link shaft, a first link 831 connected perpendicularly to the lower end of the link shaft, and a second link 832 connected perpendicularly to the upper end of the link shaft, and an angle is formed between the horizontal projections of the first link and the second link. The first link 831 and the second link 832 can be fixed to the link shaft by a clamp structure, and the first link 831 can drive the second link 832 to rotate synchronously through the link shaft. Its rotation angle is not large, and it swings back and forth within a relatively small range, which satisfies the thread take-up lever assembly to move laterally within a small range and achieve clutching. The angle between the horizontal projections of the first link and the second link can be 180 degrees, so that the first link and the second link can be arranged in the front-to-back direction. Because the thread take-up lever assembly 81 is relatively forwardly arranged, the clutch pull rod can be arranged backward to avoid interference with other components arranged in the front, which is also conducive to reducing the width space occupied by the thread take-up link component.

[0064] Furthermore, a connecting rod sleeve 833 is provided on the connecting rod shaft. The second connecting rod 832 is vertically connected to a tie rod clamp 842, which is connected to the clutch rod 84. The head housing is provided with a top plate, the second connecting rod 832 is located above the top plate, and the first connecting rod 831 is located below the top plate. The connecting rod sleeve 833 can be fixed to the top plate.

[0065] In some embodiments, the clutch drive component includes a clutch link 85 and a clutch motor 86. The clutch link 85 is connected to the clutch pull rod 84. The clutch motor 86 drives the clutch link 85 to swing, and the clutch link 85 drives the clutch pull rod 84 to move laterally. The clutch motor can be a servo motor, which can accurately control the swing angle of the clutch link.

[0066] In some embodiments, a clutch pull rod 84 is located above the mounting beam 9 and can connect the thread take-up linkage components 83 on all the tape embroidery machine heads mounted on the mounting beam. A clutch motor can be mounted on the mounting beam and located on a first lateral side of all the tape embroidery machine heads mounted on the mounting beam, that is, one clutch motor drives the thread take-up linkage components on all the tape embroidery machine heads through one clutch pull rod.

[0067] The middle portion of the clutch link 85 is connected to a connecting pin 851. The first end of the clutch link is connected to the clutch motor, and the second end is connected to the clutch pull rod. Specifically, the first end of the clutch link 85 is provided with a first elongated slot 852. The motor shaft of the clutch motor is connected to the clutch wheel 87. The eccentric portion of the clutch wheel is provided with a first pin 871, which is connected to the first elongated slot 852. The second end of the clutch link is provided with a second elongated slot 853. One end of the clutch pull rod is connected to a second pin 841, which is connected to the second elongated slot 853. Thus, when the clutch motor 86 drives the clutch wheel 87 to rotate, the eccentric arrangement of the first pin causes the lateral position of the first pin 871 to change as the clutch wheel rotates. As the first pin 871 moves along the first elongated slot 852, it can drive the clutch link 85 to swing around the connecting pin 851. During the swinging of the clutch link 85 , through the cooperation between the second elongated slot 853 and the second pin 841 , the second pin 841 can move along the second elongated slot 853 and drive the clutch rod 84 to move laterally.

[0068] In some embodiments, a clutch rail assembly 82 is further provided, comprising a clutch slider 821 and a clutch rail. The thread take-up lever assembly 81 is connected to the clutch slider 821, which slidably engages with the clutch rail, and is connected to the thread take-up link assembly 83. Therefore, the clutch slider 821 can only move laterally, driving the thread take-up lever assembly 81 to move laterally.

[0069] The clutch slider 821 is provided with an elongated drive slot 8215, and the thread take-up link component 83 is provided with a drive pin 834, which is perpendicularly connected to the end of the first link and connected to the drive slot 8215. Specifically, the clutch slider 821 is provided with a lug 8214, which extends outward from the upper end of one side of the U-shaped slot. The drive slot 8215 is provided on the lug 8214 and extends in the longitudinal direction, that is, perpendicular to the lateral sliding direction of the clutch slider 821. Therefore, when the first link 831 swings, the drive pin 834 can move relative to the drive slot 8215, simultaneously driving the clutch slider 821 to slide laterally along the clutch slide rail.

[0070] Among them, the thread take-up rod assembly 81 is rotatably installed on the thread take-up shaft 822, and the clutch slider 821 is provided with a clutch guide hole 8212. The clutch guide hole 8212 slides with the thread take-up shaft 822, so the thread take-up shaft also has the function of a clutch slide rail and does not affect the rotation of the thread take-up rod assembly.

[0071] Furthermore, the rear portion of the clutch slider is provided with a U-shaped groove 8211, within which the thread take-up lever assembly 81 connects to the thread take-up shaft. A clutch guide groove 8213 is provided at the front portion of the clutch slider. The clutch slide rail includes a clutch guide rod 823, which engages with the clutch guide rod 823. The clutch guide rod and the thread take-up shaft cooperate to guide the lateral movement of the clutch slider. Furthermore, even after the clutch slider has slid into place, the thread take-up lever assembly 81 does not rotate about the thread take-up shaft.

[0072] It can be understood that, in this embodiment, part of the structure of the tape embroidery machine is described, and other structures can refer to the existing technology.

[0073] The above description is merely a specific embodiment of the invention, but the scope of protection of the invention is not limited thereto. Those skilled in the art will understand that the invention includes, but is not limited to, the drawings and the contents described in the above specific embodiments. Any modifications that do not deviate from the functional and structural principles of the invention are intended to be included within the scope of the claims.
