Technical Field

[0001] This disclosure relates to the field of embroidery equipment technology, and more specifically, to an embroidery machine hybrid embroidery device and an embroidery machine. Background Technology

[0002] To enhance the aesthetics of clothing, beads, sequins, and Indian silk are often combined in various ways to create patterns with different three-dimensional effects.

[0035] In the various figures, the same or corresponding reference numerals indicate the same or corresponding parts. Detailed Implementation

[0036] Preferred embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While preferred embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present disclosure will be thorough and complete, and will fully convey the scope of the present disclosure to those skilled in the art.

[0037] The term "comprising" and its variations as used herein signify an open-ended inclusion, i.e., "including but not limited to". Unless otherwise stated, the term "or" means "and / or". The term "based on" means "at least partially based on". The terms "one example embodiment" and "one embodiment" mean "at least one example embodiment". The term "another embodiment" means "at least one additional embodiment". Terms such as "upper", "lower", "front", and "rear", indicating placement or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are used only for the purpose of describing the principles of this disclosure, and are not intended to indicate or imply that the elements referred to must have a specific orientation, be constructed or operated in a specific orientation, and therefore should not be construed as limiting this disclosure.

[0038] As mentioned earlier, using embroidery embellishments such as sequins, beads, and Indian silk can give the embroidered pieces a more three-dimensional feel, meeting the ever-changing aesthetic needs of modern people. Devices that combine embroidery machines with beads, or sequins with embroidery machines, have appeared on the market. Regarding Indian silk (also known as metallic silk or spring silk) embroidery, it currently relies mostly on manual operation, although devices that combine embroidery machines with Indian silk have sporadically appeared on the market.

[0039] In some related technologies, to accommodate the diversity of embroidery patterns, bead embroidery devices and sequin embroidery devices are independently installed on opposite sides of the machine head. Although a single machine head can handle both bead embroidery and sequin embroidery, the two devices operate independently under their respective needles, unable to coordinate under the same needle for mixed embroidery. To create patterns where beads and sequins overlap, sequin embroidery must be applied after bead embroidery, resulting in low efficiency and limiting the ability to achieve more complex overlapping patterns. Furthermore, both bead embroidery and sequin embroidery devices are typically complex in structure and require significant installation space. Currently, mixed embroidery devices cannot simultaneously meet the demands of mixed embroidery (including two or three techniques) while occupying minimal installation space and being compactly assembled without interference between devices.

[0040] To address this, this disclosure provides a hybrid embroidery device for an embroidery machine. The device includes a loose bead embroidery device and an Indian silk embroidery device. The silk feeding mechanism of the Indian silk embroidery device is mounted on a connecting base plate between the feeding mechanism and the unloading mechanism of the loose bead embroidery device. The silk clamping mechanism of the Indian silk embroidery device is disposed adjacent to the feeding mechanism of the loose bead embroidery device, and the silk cutting mechanism is disposed adjacent to the clamping mechanism on the side away from the feeding mechanism. The clamping component of the clamping mechanism and the feeding component of the feeding mechanism are arranged in a fan shape, allowing them to be radially aligned with the same needle. Furthermore, the clamping drive component of the clamping mechanism is arranged within the space enclosed by the feeding drive component of the feeding mechanism and the scissor drive component of the silk cutting mechanism.

[0041] In this way, the various parts of the Indian silk embroidery device are compactly assembled in different spaces within the loose bead embroidery device. In the central space of the loose bead embroidery device, the silk feeding mechanism is sandwiched between the feeding and unfeeding mechanisms, and the connecting base plate used during the installation of the loose bead embroidery device serves as the mounting plate for the silk feeding mechanism, eliminating the need for additional assembly space. In the lower space of the loose bead embroidery device, the silk clamping mechanism and the silk cutting mechanism are arranged sequentially from the inside out, adjacent to the feeding mechanism. Specifically, the silk clamping component of the clamping mechanism and the feeding component of the feeding mechanism are arranged in a fan shape, ensuring that they do not interfere with each other when moving back and forth, while still feeding the silk to the same needle. The scissors of the silk cutting mechanism are located on the side of the clamping component furthest from the feeding component, allowing the scissors sufficient room to move and smoothly cut the Indian silk. The wire clamping drive assembly of the wire clamping mechanism is located within the space enclosed by the feeding drive assembly of the feeding mechanism and the scissor drive assembly of the wire cutting mechanism. This allows for compact use of the assembly gaps between the various drive assemblies, eliminating the need for additional installation space and ensuring stable and efficient operation of each mechanism. This device can assemble Indian silk embroidery and loose bead embroidery devices together and can be installed on one side of the machine head, corresponding to the first or last needle of the needle bar frame on the machine head. This enables mixed embroidery processes under the same needle, resulting in high efficiency in mixed embroidery operations.

[0042] Figure 1 This diagram shows a perspective view of one embodiment of an embroidery machine's mixed embroidery device assembled with a machine head 300 according to an embodiment of the present disclosure. Figure 1As shown, a mixed embroidery device is installed on one side of the machine head 300 of the embroidery machine. In one example, the mixed embroidery device is installed on one side of the needle bar holder 131 of the machine head 300, such that the mixed embroidery device is set to correspond to the first needle (or the last needle) on the needle bar holder 131. This mixed embroidery device includes a loose bead embroidery device and an Indian silk embroidery device. The loose bead embroidery device can be used for loose bead embroidery of various colors or sizes, each color or size of loose bead embroidery requiring a set of hoppers 210, a feeding mechanism 220, and a feeding mechanism 230. The hopper 210 is used to load loose beads, and with the assistance of the feeding mechanism 220, the loose beads can be fed to the feeding mechanism 230. When the separating clamp assembly is opened by the separating clamp drive assembly, the material threaded on the threading wire can pass through the separating clamp assembly, allowing the separating clamp assembly to release the material on the threading wire. When the separating clamp assembly is closed by the separating clamp drive assembly, the separating clamp assembly clamps the threading wire and simultaneously blocks the material threaded on the threading wire, thereby controlling the timing of material release on the threading wire and achieving orderly feeding of multiple loose bead embroidery parts. In one example, this loose bead embroidery device can be implemented using the loose bead embroidery part disclosed in the applicant's prior application CN202511854943.5; the specific function of the part will not be described in detail here. The hopper can also be used to convey multi-gold sequin stacks to achieve multi-gold sequin stack embroidery.

[0043] like Figure 1 As shown, the embroidery machine's mixed embroidery device also includes a telescopic mechanism 400, which is typically implemented using a cylinder. This telescopic mechanism is used to push the embroidery machine's mixed embroidery device to a working position close to the needle bar frame 131 to perform the work, or to retract it to an avoidance position. Figure 2 A perspective structural diagram is shown of one embodiment of a hybrid embroidery apparatus for an embroidery machine according to an embodiment of the present disclosure. Figure 1 , 2 As shown, a vertically arranged connecting base plate B is provided between the feeding mechanism 220 and the material feeding mechanism 230. A telescopic mechanism 400 is mounted on one side of the connecting base plate B via a mounting plate A. In some embodiments, the mounting plate A is connected to the side of the needle bar holder 131 via a corner adapter L that surrounds the connecting base plate B. In this way, the loose bead embroidery device can be mounted on one side of the machine head 300.

[0044] like Figure 1 , 2As shown, the Indian silk embroidery apparatus of this embodiment includes a silk feeding mechanism 120, a silk clamping mechanism 130, and a silk cutting mechanism 140. The silk feeding mechanism 120 is mounted on a connecting base plate B between the unloading mechanism 120 and the feeding mechanism 230, and the components on the silk feeding mechanism 120 are offset from the threading wire. In one example, the mounting surface of the silk feeding mechanism 120 is perpendicular to the panel of the machine head 300. The silk feeding mechanism 120 and the telescopic mechanism 400 are respectively disposed on both sides of the connecting base plate B. Figure 1 , 2 As shown, the wire clamping mechanism 130 and the wire cutting mechanism 140 are both located below the connecting base plate B, that is, below the wire feeding mechanism 120.

[0045] Figure 3 This diagram shows a perspective view of the assembly of the wire-cutting mechanism, the wire-clamping mechanism, and the feeding mechanism of the loose bead embroidery device in a mixed embroidery apparatus of an embroidery machine according to an embodiment of the present disclosure. Figure 2 , 3 As shown, the wire clamping assembly of the wire clamping mechanism 130 and the feeding assembly of the feeding mechanism 230 are arranged in a fan shape. The wire feeding slide and the feeding slide of the feeding assembly can move back and forth and do not interfere with each other on the moving path, and can move forward to the same needle. The wire cutting mechanism 140 is located on the side of the wire clamping assembly away from the feeding assembly. It can be seen in the figure that the wire cutting mechanism 140 and the feeding mechanism 230 are respectively arranged on both sides of the wire clamping assembly. The wire clamping drive assembly of the wire clamping mechanism 130 is located behind the wire clamping assembly and is used to drive the wire clamping assembly to work from the rear end. The feeding drive assembly of the feeding mechanism 230 is located behind the feeding assembly and is used to drive the feeding assembly to work from the rear end. The scissor drive assembly of the wire cutting mechanism 140 is located behind the scissors and is used to drive the scissors to open and close from the rear end to cooperate with the wire clamping mechanism 130 to cut the Indian wire. In some embodiments, such as Figure 3 A wire clamping drive motor 139-1 of the wire clamping drive assembly is disposed between the feeding drive motor 230-1 of the feeding drive assembly and the scissor drive motor 144-1 of the scissor drive assembly. Correspondingly, other components of the drive assembly are also clamped within the space enclosed by the feeding drive assembly and the scissor drive assembly. In this configuration, the feeding drive assembly and the scissor drive assembly form a certain space from the periphery. In this embodiment, the wire clamping drive assembly is disposed within this space, resulting in a more compact installation, and all components can operate normally without interfering with each other.

[0046] To improve the compactness of the assembly, in some embodiments, the receiving guide block 230-2 of each feeding assembly is located on one side. This facilitates the compact arrangement of adjacent feeding assemblies or wire clamping assemblies.

[0047] Figure 4 A perspective structural diagram of an Indian silk embroidery apparatus according to an embodiment of the present disclosure is shown. Figure 4As shown, the silk feeding mechanism 120 includes a thread wheel assembly and a silk quantity adjustment assembly. Indian silk S is fed from the thread wheel assembly, then conveyed to the silk clamping mechanism 130 via the silk quantity adjustment assembly. The silk cutting mechanism 140 cuts the Indian silk to a preset length, and then the silk clamping mechanism 130 conveys the cut Indian silk segment to the needle insertion position of the embroidery machine to perform the Indian silk embroidery operation. The figure shows the approximate path of the Indian silk S conveyed. Along this path from the silk quantity adjustment assembly to the silk clamping mechanism 130, to prevent the Indian silk from being exposed and deformed by external interference, in some embodiments, an air tube is provided over the Indian silk. This air tube not only protects the Indian silk from being snagged, pulled, or deformed, but also guides its conveyance, ensuring it reaches the silk clamping guide post at the silk clamping mechanism 130. Furthermore, when the embroidery device operates at high speed, the mechanical vibration is severe, and the air tube also protects the stiff silk from violent shaking.

[0048] Figure 5 A front view of a wire feeding mechanism according to an embodiment of this disclosure is shown. Figure 1 , 4 As shown in Figure 5, the thread wheel assembly and the thread feeding assembly are sequentially mounted on the connecting base plate B from top to bottom. In some embodiments, the thread wheel assembly includes a thread wheel 111 and a thread wheel mounting plate 112. The thread wheel mounting plate 112 is fixed to the connecting base plate B, and the portion of the thread wheel mounting plate 112 extending upward beyond the connecting base plate B is used to mount the thread wheel 111. In addition, the thread wheel assembly also includes a thread wheel drive motor 113. The thread wheel 111 is fixed to one side of the thread wheel mounting plate 112, and the thread wheel drive motor 113 is mounted on the other side of the thread wheel mounting plate 112 via a motor mounting bracket. The motor shaft of the thread wheel drive motor 113 is connected to the thread wheel shaft of the thread wheel 111, and the thread wheel drive motor 113 can drive the thread wheel shaft to rotate, and the thread wheel 111 rotates accordingly to feed and release the thread. The embodiments of this disclosure utilize motor drive to control the thread wheel to actively feed the thread, which will not damage the shape of the thread loop and protects the thread loop of the Indian silk from deformation due to external pulling during the feeding and releasing process, thus ensuring the quality of the embroidery.

[0049] like Figure 4 , 5As shown, the yarn feeding assembly includes a roller 124-12, a roller drive motor 124-11, and a guide wheel 124-13. The guide wheel 124-13 is fitted around the roller 124-12, which rotates under the drive of the roller drive motor 124-11. The guide wheel 124-13 has a guide inlet 124-131 for Indian yarn entry and a guide outlet 124-132 for Indian yarn exit. Indian yarn (not visible in the figure) is wound around the outer circumference of the roller 124-12. The roller drive motor 124-11 drives the roller 124-12 to rotate relative to the guide wheel 124-13 to feed the Indian yarn S located between the roller 124-12 and the guide wheel 124-13 according to the required yarn feeding amount. Guide wheel 124-13 does not rotate with roller 124-12, and guide inlet 124-131 and guide outlet 124-132 remain in the same position to convey Indian silk from top to bottom. Guide wheel 124-13 can be made of ceramic or special engineering plastic, and has a certain degree of durability. Figure 6 A perspective structural diagram of a guide wheel according to an embodiment of the present disclosure is shown. Figure 6 As shown, the guide wheel 124-13 is provided with a guide groove, which is circumferentially opened on the guide wheel 124-12, allowing the Indian yarn to be wound around the outer circumference of the roller, winding in circles from the guide inlet 124-131 to the guide outlet 124-132. In some embodiments, the guide wheel 124-13 has a columnar structure, with a vertically upward extending inlet section 124-13A and a vertically downward extending outlet section 124-13B. The guide inlet is located on the inlet section 124-13A, and the guide outlet is located on the outlet section 124-13B. The inlet section 124-13A and the outlet section 124-13B have a certain length and serve a guiding function, guiding the Indian yarn into the guide wheel in the vertical direction and guiding the Indian yarn out of the guide wheel in the vertical direction. This ensures that the angle at which the Indian yarn is fed into the guide wheel does not deviate, avoiding problems such as twisting and deformation of the Indian yarn during the conveying process. In some examples, guide grooves 124-133 are formed on the inner wall of guide rollers 124-13. Guide grooves 124-133 provide a conveying trajectory for the Indian silk, ensuring that the Indian silk, constrained by the guide grooves 124-133, is drawn to the guide outlet and discharged by the frictional force generated by the roller's rolling. To prevent slippage between the Indian silk and the rollers 124-12 during rotation and to ensure speed synchronization, roller rubber rings can be installed on the outside of the rollers. This prevents direct contact between the Indian silk and the rollers, reducing the likelihood of scratches, indentations, and wear during conveying. Furthermore, the roller rubber rings also buffer mechanical vibrations and reduce transmission noise.

[0050] like Figure 4 , 5As shown, the roller drive motor 124-11 is horizontally positioned on one side of the roller 124-12, and its motor shaft is connected to the roller shaft of the roller 124-12, allowing the roller drive motor 124-11 to drive the roller 124-12 to rotate at close range. This enables timely response to embroidery requirements and precise control of the Indian silk feed amount according to the pattern strip requirements, thereby ensuring that the wire cutting mechanism can cut the metal wire segments of the preset length. In one example, the rotational angular velocity of the roller drive motor 124-11 is controlled to regulate the amount of Indian silk S fed between the roller 124-12 and the guide wheel 124-13. Combined with... Figure 1 As shown, the roller drive motor 124-11 and roller 124-12 are arranged laterally on the connecting base plate B and away from the machine head at a direction of 30°, allowing for a more compact arrangement on the mixed embroidery device of the embroidery machine. In some embodiments, the roller shaft of roller 124-12 and the motor shaft of roller drive motor 124-11 are aligned along the same central axis. In one example, the roller shaft and the motor shaft are connected by a connecting sleeve. In some embodiments, roller 124-12 and guide wheel 124-13 are housed in a mounting base and mounted below the thread wheel assembly via the mounting base. The mounting base modularly assembles the roller and guide wheel together, ensuring the clearance, parallelism, and coaxiality between the roller and guide wheel. Furthermore, the inlet and outlet sections of the guide wheel extend from the fixed opening of the mounting base. The mounting base restricts the installation space of the guide wheel, preventing micro-movement of the guide wheel during roller rotation and avoiding deflection of the Indian silk track. The mounting base can be an integral structure with a cavity that accommodates the overall shape of the roller and guide wheel, or it can be a separate assembly structure. The mounting base includes a mounting sub-base one with a accommodating groove one and a mounting sub-base two with a accommodating groove two. The accommodating groove one and the accommodating groove two, after being combined, form a cavity that accommodates the overall shape of the roller and guide wheel.

[0051] Through the above methods, this embodiment of the invention can accurately control the amount of Indian yarn fed while ensuring that the Indian yarn is delivered to the yarn clamping mechanism without wear, thus ensuring that the yarn cutting mechanism can smoothly cut the Indian yarn with a clean cut. During the yarn feeding process, the rotational angular velocity of the roller can be controlled by the roller motor to accurately control the amount of yarn fed, thereby meeting the cutting length of the Indian yarn required by the pattern strip. When the roller rotates, the Indian yarn located between the guide wheel and the roller generates friction with the contact surface between the roller and the guide wheel. This friction provides traction for the transmission of the Indian yarn, allowing it to be output from the guide inlet to the guide outlet. In particular, the way the Indian yarn forms a certain arc-shaped contact with the roller surface provides greater traction and evenly distributes the load on a circular arc, resulting in less wear and smoother operation. In this way, the Indian yarn is smoothly conveyed to the yarn clamping mechanism with almost no wear. Furthermore, the space between the roller and the guide wheel also provides shielding for the transmission of the Indian yarn, preventing it from being exposed and subjected to external interference that could cause stretching or twisting deformation.

[0052] like Figure 4 , 5 The yarn feeding mechanism 120 also includes a rocker arm assembly 122, which is mounted on the yarn reel mounting plate 112 and located between the yarn reel assembly and the yarn quantity adjustment assembly. The rocker arm assembly 122 is used to adjust the tension of the Indian yarn fed by the yarn reel assembly to the rollers 124-12. Figure 7a A perspective structural diagram of a rocker arm assembly according to an embodiment of the present disclosure is shown. Figure 7b A side view of a rocker arm assembly according to an embodiment of the present disclosure is shown. Figure 7a , 7b As shown, the rocker arm assembly 122 includes a rocker arm fixing plate 122-1, a rocker arm 122-2, a rocker arm pivot 122-3, and a rocker arm torsion spring 122-4. The rocker arm assembly 122 is fixed below the reel assembly via the rocker arm fixing plate 122-1 (see [reference]). Figure 1 For example, it is fixed on the reel mounting plate 112 of the reel assembly. A rocker arm pivot 122-3 passes through the rocker arm fixing plate 122-1, with one end of the pivot 122-3 connected to the rocker arm 122-2. The rocker arm 122-2 swings around the pivot 122-3. A rocker arm torsion spring 122-4 is sleeved on the rocker arm pivot 122-3, for example, between the rocker arm fixing plate 122-1 and the rocker arm 122-2. The extended section of the rocker arm torsion spring 122-4 is connected to the rocker arm 122-2, for example, at a point on the rocker arm furthest from the pivot connection point. Thus, the rocker arm torsion spring 122-4 provides a certain torque for the rocker arm 122-2 to swing, and the rocker arm 122-2 can swing back and forth under the action of the rocker arm torsion spring 122-4. Among them, the extended section 122-41 of the rocker arm torsion spring 122-4 is a torsion spring section that extends downward from one end of the torsion spring, and the extended section 122-41 hooks the rocker arm 122-2 with a hook-like structure.

[0053] In some embodiments, the free end of the lever 122-2 is used for passing Indian yarn through and conveying it to the lower roller. In other embodiments, the free end of the lever 122-2 is provided with a threading sleeve 122-5 for passing Indian yarn through and conveying it to the roller 124-12. This threading sleeve 122-5 is a ring-shaped ceramic sleeve structure with a certain thickness, which can be used to flatten the Indian yarn and smoothly guide it to the lower roller.

[0054] In some implementations, the rocker arm assembly 122 further includes a magnet and a Hall effect sensor plate 122-8 (e.g., Figure 7b The Hall sensor plate 122-8 is mounted on the rocker arm fixing plate 122-1 and is used to sense the magnet mounted on the rocker arm shaft 122-3. In one example, the magnet is located at the end of the rocker arm shaft and close to the Hall sensor plate. The Hall sensor plate 122-8 senses the rotation angle of the rocker arm shaft 122-3 by detecting the position of the magnet, thereby determining the tension of the Indian yarn being fed by the rocker arm. The Hall sensor plate 122-8 is communicatively connected to the yarn drive motor of the yarn reel assembly and can feed back the sensed information to the yarn drive motor. When there is enough Indian yarn, the rocker arm 122-2 returns to the limit position (as mentioned below) under the torque of the rocker arm torsion spring 122-4 and stops, and the yarn drive motor stops working, thus stopping the yarn feeding. When there is not enough Indian silk, the torque of the swing arm torsion spring 122-4 is pulled forward under the tension of the silk. When it swings to a certain extent, the Hall sensor plate senses the magnet and feeds back the sensing information to the spool drive motor. The spool drive motor starts and actively feeds and releases the silk, and so on.

[0055] In some embodiments, the swing arm assembly 122 further includes a swing arm limiting post 122-6 to limit the maximum stroke of the swing arm to one side, preventing excessive swing amplitude and thus excessive extraction of Indian silk. In one example, the swing arm limiting post 122-6 is mounted on the swing arm fixing plate 122-1, limiting the swing arm's swing trajectory. Furthermore, the swing arm assembly 122 also includes a slider 122-7, which moves on a groove 122-11 in the swing arm fixing plate 1. This groove 122-11 is an arc-shaped groove with the same curvature as the swing arm's swing trajectory. The slider is pre-positioned according to the embroidery speed requirements. By adjusting the position of the slider 122-7 within the groove 122-11, the torque of the swing arm torsion spring can be adjusted, thereby adjusting the swing amplitude of the swing arm and controlling the speed of actively feeding Indian silk until the embroidery speed requirements are met. In this way, by adjusting the position of the sliding component to adapt to the Indian silk feeding at different embroidery speeds, it can be ensured that the Indian silk is not only supplied in a timely manner, but also that there is no excessive accumulation of Indian silk on the swing arm assembly due to excessive feeding speed.

[0056] The wire feeding mechanism in this embodiment of the disclosure further includes a wire guide roller assembly. For example... Figure 4 ,5 As shown, one or more of the thread guide roller assembly can be provided, for example, between the thread wheel assembly and the rocker arm assembly 122, or between the rocker arm assembly 122 and the rollers 124-12. This thread guide roller assembly is used to guide the Indian yarn. In some embodiments, the thread guide roller assembly includes a thread guide roller and a thread guide stop pin. The thread guide roller is mounted in different positions by fixing pins, such as on the rocker arm fixing plate 122-1, or on the thread wheel mounting plate 112. The Indian yarn passes around the thread guide roller, and the thread guide stop pin is used to prevent the Indian yarn from detaching from the thread guide roller.

[0057] Figure 8 A perspective view is shown illustrating the cooperation between the wire clamping mechanism 130 and the wire cutting mechanism 140 of the Indian silk embroidery apparatus according to an embodiment of the present disclosure in cutting the Indian silk S. Figure 8 As shown in the figure, a portion of Indian silk S is output as an example. Indian silk S is clamped at the clamping opening 132-1 of the silk clamping mechanism 130. The scissors of the silk cutting mechanism 140 extend between the clamping guide post 134 and the clamping opening 132-1, and can cut the Indian silk S in the vertical direction held by the silk clamping mechanism 130. In some embodiments, the scissors include two moving blades. The two moving blades move towards each other, enabling rapid and smooth cutting of the Indian silk with a clean cut. The cut Indian silk segment can be quickly and effectively separated from the two moving blades without tangling on them, thus preventing deformation from being dragged by the blades. Furthermore, because the silk quantity adjustment component can quantitatively transfer the Indian silk to the clamping mechanism with almost no wear, the silk cutting mechanism can cut Indian silk segments of a predetermined length. Moreover, the cut Indian silk segments are wear-free, highly straight, and have a clean cut, thereby ensuring the quality of the Indian silk embroidery.

[0058] Figure 9 A perspective structural diagram of a wire clamping mechanism according to an embodiment of the present disclosure is shown. Figure 9 As shown, the wire clamping mechanism includes a wire clamping drive assembly and a wire clamping assembly. The wire clamping assembly includes a wire clamping slider 136, a wire clamping base 138, and a wire clamping slide block 132. The wire clamping slide block 132 has a wire clamping opening 132-1, which is used to clamp the Indian wire transmitted by the wire feeding mechanism. The opening 132-1 is located on a protrusion of the wire clamping slide block 132 and has a certain depth to accommodate a certain length of Indian wire. The wire clamping slide block 132 is located above the wire clamping slider 136 and the wire clamping base 138. Driven by the wire clamping drive assembly, the wire clamping slider 136 can move back and forth along the wire clamping base 138. In some embodiments, a push post 136-1 is formed on the upper surface of the wire clamping slider 134, which is housed in the inclined groove 132-2 of the wire clamping slide 132. When the wire clamping slider 136 moves, the push post 136-1 abuts against the inner surface of the inclined groove 132-2, which causes the wire clamping slide 132 to move back and forth along the wire clamping base 138.

[0059] In some implementations, such as Figure 9 As shown, a guide post mounting portion 138-2 is formed on one side of the wire clamping base 138. This guide post mounting portion 138-2 is used to mount the wire clamping guide post 134 through which the Indian wire passes and is fed into the wire clamping opening 132-1 (see...). Figure 8 In one example, the wire clamping guide post 134 has a mounting arm, which is fixed to the wire clamping base 138, such as by bolts. In other embodiments, a scissor mounting portion 138-1 is formed on the other side of the wire clamping base 138, for mounting scissors with their cutting edges located below the wire clamping guide post. For example, both the moving and fixed blades of the scissors are mounted on the scissor mounting portion 138-1, with the moving blade rotating toward the fixed blade. Another example is that a scissor shaft connecting two moving blades is mounted on the scissor mounting portion 138-1.

[0060] like Figure 9 As shown, the wire clamping drive assembly includes a wire clamping drive motor 139-1 and a rocker arm 139-3. One end of the rocker arm 139-3 is connected to the wire clamping drive motor 139-1 for transmission, and the other end of the rocker arm 139-3 is rotatably connected to the wire clamping slider 136 (for example, one end of the rocker arm is connected to...). Figure 9 The wire clamping slider 136 is connected to the slider seat 136-3. The wire clamping drive motor 139-1 drives the rocker arm to swing back and forth, thereby moving the wire clamping slider 136 back and forth along the wire clamping base 138. In some embodiments, the wire clamping drive assembly also includes a transmission assembly connected between the wire clamping drive motor 139-1 and the rocker arm 139-3. This transmission assembly can be a chain and sprocket assembly or a timing belt and pulley assembly. In one example, the transmission assembly includes a driving wheel, a driven wheel, and a timing belt. The motor shaft of the wire clamping drive motor 139-1 is coaxially connected to the driving wheel. The driving wheel and the driven wheel are connected via a timing belt. The axle of the driven wheel is hinged to one end of the rocker arm 139-3. Driven by the driving wheel, the driven wheel can cause the rocker arm 139-3 to swing. To improve the stability of the swing, the transmission assembly and the wire clamping drive motor 139-1 can be fixed on the mounting plate 139-2. In addition, the mounting plate 139-2 can also be fixed on the wire clamping base 138.

[0061] Figure 10 The diagram shows a cross-sectional view of the wire clamping mechanism according to an embodiment of the present disclosure after the wire clamping drive assembly has been removed. Figure 9 The section AA is obtained from the data, and this section is located behind the push column 136-1. For example... Figure 10As shown, the bottom of the wire-clamping slide 132 is provided with a limiting boss 132-3. A limiting groove 138-31 is formed on the surface of the wire-clamping base 138. The limiting boss 132-3 is accommodated within the limiting groove 138-31 and moves within it. In some embodiments, the limiting groove 138-31 is formed on the protrusion 138-3 of the wire-clamping base 138, and a limiting boss 132-2 is provided at the bottom of the wire-clamping slide 132 directly opposite the protrusion 138-3. The wire-clamping slide 132 moves back and forth along the wire-clamping base 138, and the limiting boss 132-2 moves to the beginning or end of the limiting groove 138-31 and is stopped. The stopping point is the wire-clamping position or the embroidery position. In this way, the wire-clamping slide 132 can be prevented from moving too far back and forth along the wire-clamping base 138, thereby ensuring that the corresponding operation is effectively performed in the accurate position. When a fixed wire clamping guide post is used, the wire clamping guide post guides the Indian wire to a fixed downward position. When the wire clamping slide 132 moves to the accurate wire clamping position, the wire clamping opening 132-1 can be located directly below the wire clamping guide post, ensuring that the Indian wire is vertically guided to the wire clamping opening. The wire clamping opening vertically clamps the Indian wire, ensuring that the scissors inserted between the wire clamping opening 132-1 and the wire clamping guide post can cut the Indian wire evenly.

[0062] Figure 11 A schematic diagram of the structure of a wire clamping base according to an embodiment of the present disclosure is shown. Figure 12 A schematic diagram of the structure of a wire-clamping slide according to an embodiment of the present disclosure is shown. Figure 11 As shown, the wire clamping base 138 has a protrusion 138-3, and guide grooves 138-4 are provided on both sides of the protrusion 138-3 for the wire clamping slider 136 to slide. A limiting groove 138-31 is formed on the protrusion 138-3 of the wire clamping base, the length of which is less than the length of the guide grooves 138-4 of the wire clamping base. Figure 12 As shown, a limiting boss 132-3 is formed at the bottom of the wire clamping slide, and the limiting boss 132-3 is located at the end of the wire clamping slide away from the wire clamping opening 132-1. Figure 12 The limiting boss 132-3 in the middle can be Figure 11 It moves within the limiting groove 138-31. In some implementations, such as Figure 12As shown, the bottom of the wire-clamping slide 132 has multiple grooves 132-4, which are arranged along the length of the limiting groove 138-31 and located between the limiting boss 132-3 and the wire-clamping opening 132-1. Each groove 132-4 contains a magnet, which is located above the limiting groove 138-31. The magnetic force of the magnet attracts the wire-clamping slide downward, ensuring that the wire-clamping slide and the wire-clamping base are always in a compressed state. This provides a uniform and stable preload for the wire-clamping slide to move back and forth relative to the wire-clamping base, reducing vibration and noise. In some embodiments, the bottom surface of the wire-clamping base 138 has two through holes 138-51 and 138-52, which are respectively connected to the limiting groove 138-31 at the beginning and end of the groove. The two through holes mentioned above can be used as drainage channels to allow debris generated during use to fall from the bottom, preventing it from accumulating in the groove and hindering the movement of the boss. On the other hand, they can be used for lubrication or ventilation to ensure that the limiting boss moves smoothly in the limiting groove.

[0063] In some embodiments, the height of the portion of the wire-clamping slider 136 located on both sides of the protrusion 138-3 is flush with the height of the protrusion 138-3. This allows the bottom surface of the wire-clamping slide block 132 to move smoothly on the upper surfaces of the wire-clamping slider 136 and the protrusion 138-3. In other embodiments, Figure 13 A schematic diagram of the wire-clamping slider according to an embodiment of the present disclosure is shown. In the diagram, push posts 136-1 are formed on the sliding portions 136-2 on both sides of the wire-clamping slider 136. The sliding portion with the push post 136-1 is slightly higher than the other portions of the sliding portion 136-2. Thus, when the height of the sliding portion 136-2 with the push post 136-1 is flush with the height of the protrusion 138-3, the height of the other portions of the sliding portion 136-2 is lower than the height of the protrusion 138-3 (at this time, a gap is left between the sliding portion 136-2 and the wire-clamping slide block 132, see [reference]). Figure 10 In this manner, the wire clamping slide 132 is moved back and forth by the push column 136-1 on the front side of the wire clamping slider 136, which reduces the friction between the rear side of the wire clamping slider 136 and the wire clamping slide 132. Combined with the magnetic adsorption between the wire clamping slide 132 and the wire clamping base 138, it can move smoothly and stably back and forth, which improves the durability of the wire clamping mechanism.

[0064] Figure 14 A schematic diagram showing the transmission connection between scissors and a scissors drive assembly according to an embodiment of the present disclosure is provided. Figure 14 As shown, the scissors consist of a first moving blade 142-1 and a second moving blade 142-2 connected via a scissor pivot 142-3. In one example, the scissors are mounted on one side of the wire clamping mechanism 130 (see [reference]). Figure 4 ). Combination Figure 8As can be seen, the shearing section formed by the first moving blade 142-1 and the second moving blade 142-2 is located between the wire clamping guide post 134 and the wire clamping opening 132-1. The shearing section is spaced apart from the wire clamping opening 132-1 and the wire clamping guide post 134, respectively. The shearing section can cut the Indian silk in the vertical direction where the Indian silk is clamped, and can quickly and smoothly cut the Indian silk, with a clean cut. The cut Indian silk segment can be quickly and effectively separated from the two moving blades. The distance between the shearing section and the wire clamping opening and the wire clamping guide post should not be too large, and should be kept at a small gap so that the scissors are not jammed. This can avoid the problem that the Indian silk will be squeezed and pulled by the scissors during the cutting process due to the large gap, which would prevent the Indian silk from being cut. In some embodiments, such as Figure 8 As shown, the first moving blade 142-1 is positioned above the second moving blade 142-2. A gap exists between the first moving blade 142-1 and the wire-clamping guide post 134, and a gap exists between the second moving blade 142-2 and the wire-clamping slide. When the first moving blade 142-1 and the second moving blade 142-2 are open, the Indian silk is allowed to pass from top to bottom through the wire-clamping guide post and be clamped by the wire-clamping opening of the wire-clamping slide below. When the first moving blade 142-1 and the second moving blade 142-2 are closed, the Indian silk can be cut below the wire-clamping guide post 134. The two moving blades are staggered vertically, utilizing sliding cutting to enhance the shearing force, effectively cutting the Indian silk, thus facilitating smoother separation during bidirectional separation.

[0065] like Figure 14 As shown, the scissor drive assembly includes a first swing arm 146-1, a second swing arm 146-2, a drive rod 148, and a scissor drive motor 144-1. The tail of the first moving blade 142-1 and the tail of the second moving blade 142-2 are connected via the first swing arm 146-1, which is also connected to the second swing arm 146-2. The first swing arm 142-1 and the second swing arm 146-2 are arranged at an angle. The scissor drive motor 144-1 drives the drive rod 148 to swing, thereby sequentially driving the first swing arm 146-1 and the second swing arm 146-2 to swing, thus realizing that the first moving blade 142-1 and the second moving blade 142-2 move towards each other or away from each other.

[0066] In some implementations, such as Figure 14As shown, a scissor clamping block 142-4 is fitted onto the scissor shaft 142-3, and a scissor compression spring 142-5 is provided between the scissor clamping block 142-4 and the first moving blade 142-1. The scissor clamping block 142-4 can be used to adjust the distance between the two moving blades. With the cooperation of the scissor compression spring 142-5, the two moving blades can generate a relatively constant closing force, so that the blades maintain slight contact or a small gap when there is no shearing force. This prevents the Indian silk from falling into the gap between the blades and ensures accurate shearing position. In addition, the scissor compression spring can also provide stability for shearing. During shearing, it can provide a certain holding force for the clamped Indian silk to prevent the Indian silk from slipping. After shearing, the spring can return the blades to a slightly closed state for the next shearing.

[0067] In some embodiments, a return spring is also connected between the tail of the first moving blade 142-1 and the tail of the second moving blade 142-2. In one example, a first spring connecting pin is provided on the bottom surface of the tail end of the first moving blade 142-1, and a second spring connecting pin is provided on the ground surface of the tail end of the second moving blade 142-2. The two ends of the return spring are hooked onto the first spring connecting pin and the second spring connecting pin, respectively. In this way, after shearing, both moving blades can be quickly returned to their initial open position.

[0068] In some implementations, the first connection point where the first moving blade 142-1 connects to the first swing arm 146-1 is closer to the scissor shaft 142-3 than the second connection point where the second moving blade 142-2 connects to the first swing arm 146-1. In one example, the first connection point is located closer to the scissor shaft 142-3, and the second connection point is located closer to the tail end of the second moving blade 142-2. This allows the first swing arm 146-1 to swing within a certain range, enabling the two moving blades to rotate within a certain range. This not only balances the shearing force and engagement depth, resulting in a smooth cut after shearing, but also allows the blade to open at a certain angle, facilitating the smooth release of the Indian silk without interfering with the scissors.

[0069] In some embodiments, the first moving blade 142-1 is connected to the first swing arm 146-1 via a first bearing pin, and the first bearing pin is fitted with a first ball bearing 142-11 located between the first moving blade 142-1 and the first swing arm 146-1. The second moving blade 142-2 is connected to the first swing arm 146-1 via a second bearing pin, and the second bearing pin is fitted with a second ball bearing 142-21 located between the second moving blade and the first swing arm 146-1. In this way, the inner ring of the ball bearing rotates with the moving blade, and the outer ring swings with the swing arm, enabling high-speed, low-wear, high-frequency shearing motion of the two moving blades.

[0070] In some embodiments, the first swing arm 146-1 and the second swing arm 146-2 are connected by a connecting pin. Flange bearings are provided on both sides of the connecting pin to clamp it, ensuring stable oscillation and transmission between the swing arms. Furthermore, to improve the stability of the oscillation, the connection between the second swing arm 146-2 and the first swing arm 146-1 is fixed to the motor base 139-2 via a support seat 139-3 (see [link]). Figure 8 ).

[0071] In some embodiments, the drive rod 148 is shaft-connected to the second swing arm 146-2. In other embodiments, the drive rod 148 drives the second swing arm 146-2 to rotate. For example, the second swing arm 146-2 is provided with a second swing arm shaft, and the second swing arm shaft is fitted with a third ball bearing 146-21. One end of the drive rod 148 is connected to the scissor drive motor 144-1, and the other end is used to push the third ball bearing 146-21 to drive the second swing arm 146-2 to swing.

[0072] In some embodiments, the scissor drive assembly further includes a driving pulley (not shown), a driven pulley 144-3, and a belt 144-4. A scissor drive motor 144-1 drives the driving pulley to rotate. The driving pulley is connected to the driven pulley 144-3 via the belt 144-4, and the driven pulley 144-3 is connected to the drive rod 148 via a pulley pin. In some embodiments, the scissor drive assembly further includes a tensioning pulley 144-5, which is tensioned at the belt 144-4 between the driving pulley and the driven pulley 144-3. The tensioning pulley 144-5, the driving pulley, and the driven pulley 144-3 are not collinear. In one example, the tensioning pulley 144-5 may be tensioned outside the belt 144-5. In another example, the tensioning pulley may be tensioned inside the belt. The driving force is transmitted by the belt, which can stably drive the drive rod 148 to rotate around the pulley pin, and then stably transmit it to the second swing rod 146-2 and the first swing rod 146-1 in sequence.

[0073] Figure 15 A front view is shown of another embodiment of an embroidery machine with a mixed embroidery device assembled with a machine head according to an embodiment of the present disclosure. Figure 16 A bottom view is shown below, illustrating another embodiment of an embroidery machine hybrid embroidery device assembled with a needle bar holder according to an embodiment of the present disclosure. Figure 15 and Figure 16 The embodiments shown are the same as Figures 1-3 The difference in the illustrated embodiment is that, in one embodiment of this disclosure, the embroidery machine's mixed embroidery device further includes a sequin embroidery device 500. This sequin embroidery device 500 is mounted below the wire feeding mechanism 120 and adjacent to the wire cutting mechanism 140, with the wire feeding mechanism of the sequin embroidery device 500 facing the needle bar holder 131. In one embodiment, Figure 16The machine comprises three sets of feeding mechanisms 230 and one set of wire clamping mechanisms 130. A wire cutting mechanism 140 is installed on the other side of the wire clamping mechanism 130. The three sets of feeding components and the wire clamping components are arranged in a fan shape. In this arrangement, a sheet feeding mechanism is arranged beside the wire cutting mechanism 140, facing the needle bar frame, so that the sheet feeding mechanism, the wire clamping mechanism 130, and the feeding mechanism 230 all correspond to the same needle. In other embodiments, the position of the sheet feeding mechanism will vary depending on the number of mechanisms arranged on the mixed embroidery device of the embroidery machine; the sheet feeding mechanism may be tilted towards the needle bar frame.

[0074] like Figure 15 As shown, the sequin embroidery device includes a retraction mechanism and a feeding mechanism. The retraction mechanism can use a retraction drive motor, guide rails, or other structures to achieve the forward and backward movement of the feeding mechanism. The feeding mechanism can be a widely used feeding mechanism in the prior art, and can be a feeding mechanism for single sequins, stacked sequins, or multiple sequins. The feeding mechanism typically includes a conveying groove for conveying the corresponding sequins, a corresponding cutter located at the outlet of the conveying groove, a deflector rod for driving the sequins along the conveying groove, a drive motor for driving the deflector rod and the cutter, and necessary transmission structures. A sequin tray can be mounted on the feeding mechanism. The sequin embroidery device 500 is connected to the connecting base plate B via a connecting seat 501. In some embodiments, a motor mount plate for a roller drive motor is provided on the outer side of the connecting base plate B. The upper part of the connecting seat 501 is connected to the motor mount plate, and the lower part is connected to the retraction mechanism of the sequin embroidery device 500 and the feeding mechanism located below the retraction mechanism.

[0075] In this way, three types of embroidery devices—bead embroidery, Indian silk embroidery, and sequin embroidery—can be integrated into a single device and installed on one side of the same machine head. In particular, the Indian silk embroidery device is divided into multiple parts and clamped within the bead embroidery device. The silk clamping and feeding components are arranged in a fan shape around the same needle, making full use of the installation space on the side of the machine head, allowing for compact assembly and mutual complementarity. This allows various embroidery materials to work together to create more three-dimensional and complex patterns.
