Description

TECHNICAL FIELD

[0001] One or more embodiments of the present disclosure relate to the technical field of embroidery machines, in particular to a disc tape embroidery device and an embroidery machine. BACKGROUND

[0002] The disc tape embroidery device is used for embroidering tape and / or rope and the like. The disc tape embroidery device generally consists of a machine shell, a driving main shaft, a needle bar, a feeding part, a presser foot part, and a thread tensioning lever part. In order to improve the continuous working time of disc tape embroidery, the existing feeding part adopts a large-size tray to carry a large-capacity tape. During the disc tape embroidery operation, the needle of the machine is lowered to pierce the embroidery material, and the face thread locks the rope or tape on the embroidery material. At this time, the embroidery frame is moved, which will move the rope / tape. When the size of the tray is increased, the rope or tape will be mechanically pulled out of the tray. There is a large pulling force between the embroidery frame and the tray, which will deform the embroidery product and cause the embroidery product to be defective. If a feeding motor is provided on the tray, the feeding motor is used to drive the tray to actively feed, so as to cooperate with the movement of the embroidery frame.

[0003] In some related technologies, the disc tape embroidery device is equipped with a rope winding and unwinding mechanism and a tensioning mechanism, which cooperate with each other to adjust the tension of the rope and realize automatic winding and unwinding of the rope. However, the above structure is relatively complex and occupies installation space, and a large number of disc tape embroidery devices cannot be installed on the embroidery machine. Moreover, the rope is output from the tray rack, and the tensioning and winding and unwinding of the rope are realized by three different mechanisms, which requires a control system to cooperatively control the movement of the embroidery frame during the disc tape embroidery operation, and the control requirement is high and the control process is more complex.

[0004] In the prior application patent CN113584748B of the applicant, a feeding rack and a feeding lifting driving mechanism are added to the disc tape embroidery device. When adding, the presser foot lifting driving mechanism of the existing disc tape embroidery device is also changed accordingly, the guide column in the presser foot lifting driving mechanism is extended to vertically pass through the machine shell, so that the end of the guide column is connected with the feeding sleeve. In this way, the guide column is not only used as a guide rod of the presser foot lifting driving mechanism, but also used as a driving rod of the feeding lifting driving mechanism. Since the two lifting driving mechanisms share the guide column, although the disc tape embroidery device is more compact, it cannot be directly assembled on the existing disc tape embroidery device, and the existing guide column of the disc tape embroidery device needs to be replaced with a longer guide column, and the machine shell needs to be opened. Moreover, the arrangement range of the feeding transmission assembly and the feeding driving motor is also limited by the position of the guide column. Furthermore, during use, the feeding lifting driving mechanism drives the guide column to lift and lower, and the guide column passes through the two guide plates of the presser foot connecting piece and the lifting driving piece. During repeated movement, there is a certain friction, which will affect the stability of the lifting and lowering of the presser foot in the vertical direction driven by the presser foot lifting driving mechanism. Once the guide column is broken due to failure of the presser foot or the feeding rack during lifting and lowering, the lifting and lowering functions of the presser foot and the feeding function will be affected. The utility model discloses

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present disclosure will be described clearly and completely below with reference to the drawings in the embodiments of the present disclosure.

[0025] The preferred embodiments of the present disclosure will be described in more detail below with reference to the drawings. Although the preferred embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present disclosure more thorough and complete, and to fully convey the scope of the present disclosure to those skilled in the art.

[0026] The term "includes" and its variants are meant to cover a non-exclusive inclusion, such that a process, method, system, product, or apparatus that comprises a list of elements is not necessarily limited to those elements, but can include other elements not expressly listed or inherent to such process, method, system, product, or apparatus. The term "or" means "and / or" unless clearly indicated otherwise. The term "based on" means "based, at least in part, on." The terms "one example embodiment" and "an embodiment" mean "at least one example embodiment." The term "another embodiment" means "at least one additional embodiment." The terms "upper," "lower," "front," "back," and the like, when used to describe the orientation or position of a component, are used based on the orientation or position as shown in the figures and are merely used for convenience in describing the principles of this disclosure and are not meant to limit or imply the specific orientation, construction, or operation of the component, and thus should not be construed as limiting the disclosure in this manner.

[0027] As mentioned above, the disc-belt embroidery device needs to use the disc belt to convey the belt material (such as a rope or a belt) to the presser foot. The needle under the needle pierces the embroidery material, and the face thread locks the belt material on the embroidery material, and the continuous operation can complete the disc-belt embroidery. During the disc-belt embroidery operation, the face thread locks the belt material on the embroidery material, at this time, the embroidery frame is moved, and the embroidery frame will move the belt material. The belt material will be pulled out from the disc by the embroidery frame, and the larger the disc, the greater the pulling force, which may deform the embroidery product, resulting in poor embroidery.

[0028] In the prior application patent of the applicant, the disc-belt embroidery device is additionally provided with a feeding frame and a driving mechanism thereof, which can use the lifting or swinging of the feeding frame to pre-pull the belt material from the disc frame, and then move the embroidery frame, so that the belt material between the embroidery frame and the disc frame is not tightened, and the belt material is not excessively pulled when the embroidery frame is moved. However, there are the following problems. On the one hand, the guide column used for the presser foot lifting part is used in multiple ways, that is, it is used as a guide rod of the presser foot lifting part and a driving rod of the feeding lifting, which needs to change the original guide column according to the needs of the feeding lifting, and also needs to open a hole on the machine shell to adapt the stroke of the feeding lifting. In this way, the feeding frame and the driving mechanism thereof cannot be simply added to the existing disc-belt embroidery device for use, and the existing disc-belt embroidery device needs to be modified. On the other hand, in the use process, the feeding lifting driving mechanism drives the guide column to lift, and the guide column passes through the two guide plates of the presser foot connecting piece and the lifting driving piece, and there is a certain friction in the repeated movement process, which will affect the stability of the guide column driven by the presser foot lifting driving mechanism to drive the presser foot to lift in the vertical direction. Once the guide column is broken during the lifting process of the presser foot or the feeding frame, the presser foot lifting function and the feeding function are affected, and the presser foot and the feeding part structure need to be replaced at the same time, which has a high maintenance cost.

[0029] In view of this, according to the embodiment of the present disclosure, a feeding driving mechanism including a feeding driving rod is designed, so that the presser lifting driving has its own independent guide column for presser lifting, and the feeding lifting function is realized through the independent feeding driving rod. In this way, the hole for the feeding driving rod to pass through can be opened or not opened on the existing disc tape embroidery device shell, and the feeding driving mechanism is directly installed on the existing disc tape embroidery device, so that the feeding function can be realized. In this way, not only the presser part structure does not need to be changed, but also the installation of the feeding driving mechanism is not limited by the inherent position of the guide column, and the feeding lifting function and the presser lifting function are independently realized, so that they do not affect each other, the service life is long, the lifting stability is good, and once a part fails, the device of the part can be replaced and maintained alone.

[0030] Figure 1 The structure diagram of the disc tape embroidery device 10 according to the embodiment of the present disclosure is shown. As shown in the figure, Figure 1 The disc tape embroidery device 10 includes a shell 101, a needle bar part, a presser part, and a tray part 102. The needle bar part includes a needle bar 103 and a needle bar driving mechanism, and the needle bar 103 is vertically arranged through the shell 101. The needle bar driving mechanism includes a cam and a connecting rod mechanism for driving the needle bar 103 to move up and down. The presser part includes a presser mounting member 110, a presser sleeve 104, and a presser lifting driving mechanism. The presser sleeve 104 is sleeved on the needle bar 103, and the presser mounting member 110 is connected to the presser sleeve 104. The presser mounting member 110 is used for mounting a presser and a nozzle (not shown in the figure, wherein the presser here is a presser for threading a tape, and the nozzle is used for threading a rope). The tray part 102 includes a tray rack and a tray. The tray is mounted on the tray rack (one or more can be provided). The tray is used to deliver a rope or a tape to the place to be embroidered for disc tape embroidery.

[0031] As shown in the figure, Figure 1 The presser lifting driving mechanism includes a presser driving motor 109-1 and a presser guide rod 109-2. The presser guide rod 109-2 is used for guiding the presser sleeve 104 during lifting, and the two are connected through a lifting driving member and a presser connecting member which are sleeved outside the presser guide rod 109-2. The presser connecting member has a part of the driving fork which is arranged outside the presser sleeve 104. When the presser driving motor 109-1 drives the lifting driving member to move up and down, the lifting driving member moves along the length direction of the presser guide rod 109-2, and the presser connecting member also moves along the length direction of the presser guide rod 109-2, so that the presser sleeve 104 connected with the presser connecting member also lifts, and the presser or the nozzle connected to the presser sleeve 104 also lifts.

[0032] As shown in the figure, Figure 1As shown, the disc tape embroidery device 10 further comprises a rotating driving mechanism 111 mounted on the casing 101 for driving the disc holder of the disc portion 102 to rotate. The disc holder is fixed on the first shaft sleeve 105 which is sleeved on the presser sleeve 104, and the first shaft sleeve 105 is rotationally connected on the casing 101 or the beam of the embroidery machine. The first shaft sleeve 105 rotates under the driving of the rotating driving mechanism 111, thereby driving the disc holder to rotate.

[0033] As shown, Figure 1 The disc tape embroidery device 10 further comprises a second shaft sleeve 106, a feeding member 107, and a feeding driving mechanism. The second shaft sleeve 106 is sleeved on the first shaft sleeve 105, and the feeding member 107 is mounted on the second shaft sleeve 106. The feeding driving mechanism is arranged on the casing 101 for driving the second shaft sleeve 105 to move up and down, thereby driving the feeding member 107 to move up and down in the vertical direction, and realizing the pulling and dropping of the tape during the up and down movement. When the first shaft sleeve 105 rotates under the driving of the rotating driving mechanism 111, the second shaft sleeve 106 rotates under the driving of the first shaft sleeve 105, so that the feeding member 107 rotates with the disc holder.

[0034] The feeding driving mechanism comprises a feeding driving motor 108-1 and a feeding driving rod 108-2. One end of the feeding driving rod 108-2 is in transmission connection with the feeding driving motor 108-1, and the other end is connected with the second shaft sleeve 106. When the feeding driving motor 108-1 drives the feeding driving rod 108-2 to move up and down, the second shaft sleeve 106 connected with the feeding member 107 also moves up and down.

[0035] In some embodiments, the feeding drive rod 108-2 can be disposed within the housing 101, spaced a certain distance from the presser foot guide rod 109-2. For example, it can be arranged on one side of the housing or on different sides of the housing. A through hole is provided in the housing 101 for the feeding drive rod 108-2 to pass through, allowing the lower end of the feeding drive rod 108-2 to extend out of the housing 101 and connect with the second bushing 105 located below the housing 101, and also facilitating the lifting and lowering movement of the feeding drive rod. In some examples, a through hole is provided at the bottom of the housing 101 for the feeding drive rod to extend. In this example, the feeding drive rod 108-2 can be shorter than the presser foot guide rod 109-2. In other examples, a through hole is provided at the bottom of the housing 101 for the feeding drive rod 108-2 to extend, and another through hole is provided at the crossbeam of the housing 101 for the feeding drive rod 108-2 to extend. In this example, the feed drive rod 108-2 can be the same length as or longer than the presser foot guide rod 109-2. Two through holes restrict the movement of the feed drive rod 108-2, ensuring vertical lifting and lowering. Accordingly, the feed drive mechanism can be mounted on the housing, for example, in a location with mounting space inside or outside the housing. In some embodiments, for proximity and compact arrangement, the feed drive mechanism can be arranged on the housing sidewall near the feed drive rod.

[0036] In some embodiments, the feed drive rod can be located outside the housing, thus eliminating the need for a through-hole in the housing for it to pass through. In one example, the feed drive rod is mounted on the outer wall of the housing 101, or on the frame of the embroidery machine. Accordingly, the feed drive mechanism can be mounted on the housing, for example, in a location with mounting space inside or outside the housing. In some embodiments, for proximity and compact arrangement, the feed drive mechanism can be arranged on the housing side wall near the feed drive rod.

[0037] In some embodiments, the feeding drive rod 108-2 is a vertical rod, vertically disposed inside or outside the machine housing. In some embodiments, the feeding drive rod 108-2 includes at least a vertical portion, capable of moving up and down in the vertical direction, driving the second bushing 106 to move up and down.

[0038] exist Figure 1 In the example shown, the feeding drive rod 108-2 and the feeding drive motor 108-1 can be compactly arranged on the ribbon embroidery device. Only a through hole needs to be opened in the housing 101, allowing it to be installed on the ribbon embroidery device 10 without modifying the presser foot lifting drive mechanism. For example... Figure 1The feeding drive mechanism is located on the outer wall of the machine housing, and the feeding drive motor 108-1 of the feeding drive mechanism is located above the main shaft 112 passing through the tape embroidery device. The feeding drive motor 108-1 is connected to the feeding drive rod 108-2 located inside the machine housing 101 via a feeding transmission assembly installed on the side wall of the machine housing. Correspondingly, a through hole is opened at the bottom of the machine housing 101 to allow the feeding drive rod 108-2 to pass through and move vertically, and a connecting block is opened on the side wall of the machine housing 101 to allow the feeding transmission assembly and the feeding drive rod 108-2 to pass through, so that the feeding transmission assembly drives the connecting block to move in the through hole, and then the feeding drive rod 108-2 can move up and down. With the above arrangement, the feed drive motor 108-1 and the presser foot drive motor 109-1 are located above and below the main shaft 112, respectively. This makes reasonable use of the vertical space on the side of the ribbon embroidery device, so that the overall arrangement of the ribbon embroidery device is compact after the feed drive mechanism is added. It will not take up more installation space due to the addition of components. In this way, the same number of ribbon embroidery devices can still be arranged on one embroidery machine as before the feed function was added.

[0039] like Figure 1 As shown, in some embodiments, the feeding element 107 is configured according to the number of trays. That is, when there is one tray, one feeding element is configured and positioned close to that tray. When there are two trays, two feeding elements are configured, each feeding element positioned close to one tray. Figure 1 As shown, the ribbon embroidery device 10 has two material trays, and two feeding elements 107 are respectively installed on both sides of the second bushing 106. In this way, the rope or ribbon conveyed on the material tray can pass through the feeding elements 107 and be fed into the presser foot or nozzle.

[0040] In some implementations, the feeding element 107 can be a feeding frame with a feeding hole as described in a prior art invention, or it can be a feeding ring. In one example, the feeding ring can be a closed ring or an open ring with a notch, such as a three-quarter ring or a semi-circular ring. This allows the rope or belt to enter the feeding ring in any direction along the circumference of the ring, accommodating material entering from all directions as the tray rotates. Simultaneously, the ring surface guides the material to move smoothly.

[0041] In some implementations, the feeding ring has an arc-shaped concave surface at the feed inlet, and this arc-shaped concave surface is horizontally downward. For example... Figure 1As shown, the tape generally enters from above the feeding ring and is output from below, and is then sent to the lower foot or nozzle. The upper entry is the feeding port, and the lower output is the discharge port. The end face of the feeding port of the feeding ring is a circular arc end face, which extends downward toward the center of the feeding port, so that the caliber of the feeding port gradually decreases, and the overall shape is concave, which is defined as an arc-shaped concave surface in the embodiment of the present disclosure. In this way, the tape with a certain width can enter from the arc-shaped concave surface of the feeding port, and the arc-shaped concave surface can facilitate the smooth entry and flattening of the tape, and at the same time, the arc-shaped concave surface can guide the tape downward to the foot or nozzle along the direction of the arc-shaped concave surface (mainly horizontally downward). In some examples, the tape can be made to enter the feeding ring obliquely and be vertically guided out of the feeding ring, and then be inserted into the foot or nozzle.

[0042] In some embodiments, the arc-shaped concave surface of the feeding ring is arranged towards the corresponding tray on the tray rack. In this way, the tape can be guided to enter and be output to the foot or nozzle of the foot portion. In an example, the feeding ring can be vertically installed on the disc tape embroidery device 10. For example, the feeding port and the discharge port of the feeding ring are arranged on the same vertical line. In another example, the feeding ring can be obliquely installed on the disc tape embroidery device. For example, the feeding port is arranged close to the tray on the same side, and the discharge port is arranged close to the rotation center of the tray.

[0043] Figure 2 A structural schematic diagram of the feeding member 107 according to an embodiment of the present disclosure is shown. The feeding member 107 is a feeding ring, which can be a feeding sleeve ring structure, and has an arc-shaped concave surface 107-1. The tape enters from the arc-shaped concave surface 107-1 of the feeding ring and is guided out downward. With the arc-shaped guidance, the tape is flattened and guided out vertically downward after passing through the line along the direction of the arc-shaped concave surface. In Figure 2 In an example, the feeding ring has a certain thickness, which can better guide the tape to be guided out in a flattened state. In other examples, the feeding ring can be a sheet-type ring. In Figure 2 In the shown example, the feeding ring includes an upper ring portion and a lower ring portion, and the outer diameter of the upper ring portion is greater than that of the lower ring portion. In some embodiments, the feeding ring can also be a ring of other structural forms, for example, a columnar ring formed by the upper and lower ring portions having equal outer diameters.

[0044] The embodiment of the present disclosure replaces the feeding rack of the prior invention patent with a feeding ring of simple structure, so that when it is installed on the disc tape embroidery device, it can pull the tape out of the tray and send it into the feeding ring, and the feeding ring can output the flattened tape to the foot portion, ensuring that the tape locked by the face thread is smooth and the quality of the embroidery is high.

[0045] Figure 3 A structural schematic diagram of the feeding member 107 according to an embodiment of the present disclosure is shown. The feeding member 107 is a feeding ring, which can be a feeding sleeve ring structure, and has an arc-shaped concave surface 107-1. The tape enters from the arc-shaped concave surface 107-1 of the feeding ring and is guided out downward. With the arc-shaped guidance, the tape is flattened and guided out vertically downward after passing through the line along the direction of the arc-shaped concave surface. In Figure 3As shown, the mounting member 113 can be a mounting plate fixed on the second shaft sleeve 106, for example, fixed outside the second shaft sleeve 106 or fixed inside the second shaft sleeve 106. In some embodiments, the mounting member 113 further has a mounting hole allowing the feeding member 107 to be sleeved in the mounting hole. The feeding member 107 can be matched with the mounting hole without relative rotation. In some embodiments, the mounting member 111 can be welded with the feeding member 107, or screwed and fixed, or screwed.

[0046] In some embodiments, the mounting member 113 can be used to tilt the feeding member 107. In this way, the arc-shaped concave surface of the feeding member 107 can be directed towards the tray. In an example, the mounting member 113 can be an obtuse angle connector or other forms of connectors. In some embodiments, the mounting member 113 can be used to vertically mount the feeding member 107. The mounting member 113 can be a right angle connector or other forms of connectors.

[0047] In some embodiments, there are a plurality of feeding members 107, each corresponding to a tray on the tray rack and mounted on the second shaft sleeve 106. In some examples, each feeding member is mounted on the second shaft sleeve 106 through a mounting member, for example Figure 3 As shown. In some examples, a plurality of feeding members can be mounted on the second shaft sleeve 106 through a mounting member. In an example, the mounting member can be a ring-shaped plate used to fix a plurality of feeding members.

[0048] Figure 4 A schematic diagram of a feeding member, a driving mechanism for driving the feeding member to rotate and lift, and a transmission structure between the presser foot and the presser foot lifting driving mechanism according to an embodiment of the present disclosure is shown. As shown Figure 4 As shown, the feeding driving mechanism includes a feeding driving motor 108-1, a feeding transmission assembly 108-3, and a feeding driving rod 108-2. The motor shaft of the feeding driving motor 108-1 drives the feeding transmission assembly 108-3 to drive the feeding driving rod 108-2 connected with the feeding transmission assembly 108-3 to lift. The feeding transmission assembly 108-3 can be realized by using transmission components such as belt pulleys or chain wheels. The transmission structure can be arranged in a triangular shape as shown in the figure or in an elliptical shape vertically arranged, etc. In an example, the feeding transmission assembly 108-3 is composed of a transmission belt, a driving pulley, and a driven pulley. The feeding driving motor 108-1 drives the driving pulley to rotate, and the driven pulley rotates under the transmission of the transmission belt. The feeding transmission assembly 108-3 is connected with one end of the feeding driving rod 108-2, and the feeding driving rod 108-2 can be controlled to lift during the transmission of the transmission belt. The other end of the feeding driving rod 108-2 is connected with the second shaft sleeve 106 (for example, through a mounting member). Figure 4The drive fork structure in the middle realizes the connection between the feeding drive rod 108-2 and the second bushing 106. The other end of the feeding drive rod 108-2 moves up and down with the second bushing 106. Correspondingly, the feeding component 107 connected to the second bushing 106 also moves up and down.

[0049] like Figure 4 As shown, the presser foot lifting drive mechanism includes a presser foot lifting drive motor 109-1, a presser foot guide rod 109-2, a presser foot transmission assembly 109-3, and a presser foot connector. The presser foot connector is sleeved outside the presser foot guide rod 109-2. The presser foot connector is also connected to the presser foot sleeve 104. Figure 4 In the example, a lifting drive component is also fitted outside the presser foot guide rod 109-2, and the presser foot transmission assembly 109-3 is used to drive the lifting drive component to move up and down. When the lifting drive component is driven by the presser foot transmission assembly 109-3 to move up and down along the presser foot guide rod, the lower guide plate of the lifting drive component drives the presser foot connector to move upward along the presser foot guide rod, so that the presser foot sleeve 104 is carried upward by the presser foot connector, realizing the rise of the presser foot or nozzle; the upper guide plate of the lifting drive component drives the presser foot connector to move downward along the presser foot guide rod, so that the presser foot sleeve 104 is carried downward by the presser foot connector, realizing the fall of the presser foot or nozzle. In other examples, the presser foot transmission assembly 109-3 directly drives the lifting movement of the presser foot connector. When the presser foot connector rises along the presser foot guide rod, it carries the presser foot sleeve 104 up, and vice versa.

[0050] In some implementations, the connection between the presser foot connector and the presser foot sleeve can be achieved using a drive fork connection structure. In one example, the presser foot connector has a first connecting sub-component and a second connecting sub-component, which are connected together. The first connecting sub-component is sleeved on the presser foot guide rod, and the second connecting sub-component has an annular opening that engages with an annular groove in the presser foot sleeve 104.

[0051] In some implementations, the presser foot drive assembly 109-3 can be implemented using a pulley or sprocket as a transmission component. Its transmission structure can be arranged in a triangular shape as shown in the figure, or in an elliptical vertical arrangement. The presser foot drive motor 109-1 drives the drive wheel to rotate, and the driven wheel rotates under the transmission of the conveyor belt. The presser foot drive assembly 109-3 is connected to the lifting drive component, and the lifting drive component can be controlled to rise and fall during the conveyor belt transmission process. In some examples, the presser foot drive assembly 109-3 adopts a triangular transmission structure, which makes the transmission of the presser foot drive assembly more stable. Furthermore, the presser foot drive motor driving the drive wheel can be recessed between adjacent heads of the embroidery machine to avoid interfering with the embroidery work ahead.

[0052] like Figure 4As shown, the rotary drive mechanism includes a rotary drive motor 111-1, a transmission rod 111-2, and a transmission assembly 111-3. In some embodiments, the transmission assembly can adopt a master-slave pulley transmission structure. The transmission assembly 111-3 includes a driving pulley, a belt, and a driven pulley. The rotary drive motor 111-1 drives the transmission rod 111-2 to rotate, and in turn, the transmission assembly 111-3 connected to the transmission rod 111-2 also rotates, and the first shaft sleeve 105 connected in transmission with the driven pulley also rotates to drive the tray holder to rotate, and the feeding member 107 installed on the second shaft sleeve 106 also rotates. In some embodiments, the rotary drive mechanism can be used alone for the tray rotation, i.e., as a tray rotary drive mechanism, and correspondingly, the presser foot rotation is achieved through another set of presser foot rotary drive mechanism. For example, the applicant's prior invention patent CN113584748B, the presser foot rotary drive mechanism includes a presser foot drive motor and a transmission assembly. The presser foot drive motor drives the transmission assembly to act, and in turn, drives the presser foot sleeve to rotate to drive the presser foot or nozzle to rotate. In some embodiments, a set of rotary drive mechanism can be used to drive the presser foot or nozzle and the tray holder to rotate synchronously. The rotary drive motor drives the transmission assembly to drive the first shaft sleeve to rotate, and the presser foot sleeve rotates with the first shaft sleeve to drive the presser foot or nozzle of the presser foot part to rotate, while the tray holder is installed on the first shaft sleeve, and the tray holder and the feeding rack also rotate synchronously.

[0053] The embodiments of the present disclosure also provide an embroidery machine, which includes an embroidery frame and a plurality of embroidery machine heads. The plurality of embroidery machine heads includes a plurality of machine heads of flat embroidery devices and a plurality of machine heads of disc tape embroidery devices. The disc tape embroidery device can adopt the disc tape embroidery device 10 as shown. Figure 1 The plurality of machine heads (flat embroidery devices) are driven by the main shaft 112 to move synchronously. The main shaft 112 is also in transmission connection with the cam shaft of the disc tape embroidery device, and then relies on the power of the main shaft 112 to drive the cam and the connecting rod mechanism to realize the movement of the needle bar of the disc tape embroidery device. When the disc tape embroidery device and the flat embroidery device are arranged on one computer embroidery machine, the problem of mechanical wear and loose thread caused by the follow-up movement of the disc tape embroidery device during the operation of the flat embroidery device is avoided. The disc tape embroidery device also includes a separation mechanism, so that the disc tape embroidery device 10 can be separated from the main shaft 112 and stopped rotating during the operation of the flat embroidery device.

[0054] The above-described embodiments are merely preferred embodiments of the present disclosure and are not intended to limit the scope of the present disclosure. Without departing from the design spirit of the present disclosure, various modifications and improvements to the technical solutions of the present disclosure made by those of ordinary skill in the art shall fall within the protection scope determined by the claims of the present disclosure.
