Description

TECHNICAL FIELD

[0001] The utility model relates to embroidery equipment technical field more specifically, and more specifically relates to mixed embroidery device and embroidery machine. BACKGROUND

[0002] The mixed embroidery device is a combined head device capable of flat embroidery and disc tape embroidery. The disc tape embroidery head generally consists of a machine shell, a driving main shaft, a needle bar assembly, a feeding assembly, a presser foot assembly, a thread tension lever assembly, etc. The existing disc tape embroidery head rotates synchronously through a driving motor to drive the disc rack of the feeding assembly and the presser foot mounting member of the presser foot assembly (which is installed with a presser foot for threading a tape and a nozzle for threading a rope. The presser foot described in this document is an auxiliary presser foot for disc tape embroidery, not the presser foot used in flat embroidery. The disc tape embroidery head is also installed with a presser foot used in flat embroidery, but it is not shown in the figure, and this will not be described in this document. ) The size of the disc rack is increased to carry a large capacity of tape. As the size of the disc rack increases, the load also increases. The disc tape embroidery head needs to run at high speed. When the disc rack and the presser foot mounting member rotate synchronously, the rotational inertia is large, and the disc rack is not easy to brake and turn around. Therefore, the speed of the existing disc rack is controlled at 600-700 rpm. During the operation of the disc tape embroidery head, the disc rack rotates stiffly, causing severe mechanical wear and reducing the embroidery efficiency.

[0003] Therefore, the applicant previously applied for a disc tape embroidery device with publication number CN113584749B. The device includes a machine shell, a needle bar assembly, a presser foot assembly, and a disc rack. The needle bar of the needle bar assembly vertically penetrates the machine shell, and the presser foot sleeve of the presser foot assembly is sleeved outside the needle bar. The presser foot sleeve is sleeved with a fixed sleeve, and the fixed sleeve is sleeved with a shaft sleeve. The fixed sleeve is fixed on the machine shell. The presser foot assembly includes a presser foot mounting member connected to the presser foot sleeve and a presser foot rotation driving mechanism. The presser foot mounting member is used to install the presser foot and the nozzle. The disc rack includes a disc rack and a disc driving mechanism. The disc driving mechanism drives the shaft sleeve to rotate to drive the disc rack to rotate. The presser foot rotation driving mechanism drives the presser foot sleeve to rotate to drive the presser foot mounting member to rotate.

[0004] The above-mentioned disc tape embroidery device solves the problem of the existing disc rack and presser foot mounting member synchronously rotating due to the large size of the disc rack, which cannot meet the high-speed operation of disc tape embroidery. The control is more flexible, the mechanical wear is reduced, and the embroidery efficiency is improved. However, when it is applied to a mixed embroidery device, the head distance between the flat embroidery head and the disc tape embroidery head is easily increased, which limits the number of head installations and cannot form a mixed embroidery device with a larger embroidery scale.

[0052] The present invention will be illustrated with specific examples below:

[0053] Example 1:

[0054] Mixed embroidery device, as shown in the attached document Figure 1 As shown, the device mainly includes a horizontally extending main beam a, and a flat embroidery head b and a ribbon embroidery head c connected to the main beam a. The mixed embroidery device also includes a main shaft c9 that extends horizontally and drives the ribbon embroidery needle bar c2 to perform embroidery actions. The main shaft c9 passes through the flat embroidery head b and has a portion placed between the flat embroidery needle bar holder b2 and the main beam a.

[0055] At least one flat embroidery head (b) and one ribbon embroidery head (c) are provided. Each head is fixedly connected to the main beam (a) by means of screws, for example, and the two heads are arranged adjacent to each other in the transverse direction. Of course, multiple flat embroidery heads (b) and ribbon embroidery heads (c) can also be provided, arranged in a staggered manner in the transverse direction (as shown in the attached diagram). Figure 1 As shown, one flat embroidery head b and one ribbon embroidery head c are arranged in a horizontal arrangement; or multiple flat embroidery heads b and multiple ribbon embroidery heads c can be arranged arbitrarily in the horizontal direction according to the embroidery requirements.

[0056] Among them, for the coil embroidery machine head c:

[0057] As attached Figure 2 To be continued Figure 5 As shown, it mainly includes: a tape embroidery machine housing c1 for connecting to the main beam a and for assembling various parts; a needle bar assembly for embroidering the tape into the fabric; a presser foot assembly for pressing and positioning the fabric in conjunction with the embroidery action; and a tray assembly for placing the tape (tape and / or rope and other strip-shaped objects).

[0058] Among them, as attached Figure 2As shown, the needle bar assembly mainly comprises a vertical shaft structure of the disc band embroidery needle bar c2, which passes through the disc band embroidery machine shell c10 in the vertical direction, and the lower end of the disc band embroidery needle bar c2 penetrates out of the disc band embroidery machine shell c10 downward and is connected with the embroidery needle. At the same time, the needle bar assembly further comprises a disc band embroidery needle bar driving connection structure (generally composed of a cam and a connecting rod mechanism) connected to the disc band embroidery needle bar c2, which is drivingly connected with the main shaft c9 of the embroidery machine when the disc band embroidery machine head c is connected to the beam a, so that when the main shaft c9 of the embroidery machine rotates, the disc band embroidery needle bar c2 can be driven to move up and down by the disc band embroidery needle bar driving connection structure to perform the embroidery action.

[0059] The presser foot assembly mainly comprises a presser foot tube c3 rotatably sleeved (in this application, sleeving refers to direct sleeving, that is, the sleeving member is directly opposite the sleeved member without other members between the sleeving member and the sleeved member; or indirect sleeving, that is, the sleeved member is sleeved with other members on the outer periphery, and the sleeving member is sleeved on the outer periphery of the member to achieve sleeving on the outer periphery of the sleeved member) on the outer periphery of the disc band embroidery needle bar c2. The presser foot tube c3 is a sleeve structure sleeved on the outer periphery of the disc band embroidery needle bar c2 and can rotate around the disc band embroidery needle bar c2 as the central axis. The lower end of the presser foot tube c3 penetrates out of the disc band embroidery machine shell c10 downward and is connected with a presser foot connecting member c4 for mounting a presser foot. According to requirements, the presser foot connecting member c4 can also be synchronously mounted with a nozzle, a swing rod and other auxiliary assembly parts. The presser foot assembly further comprises a presser foot rotation driving mechanism for driving the presser foot tube c3 to rotate, which comprises a presser foot rotation driving motor c5.1.

[0060] The tray assembly mainly comprises a tray tube c6 sleeved on the outer periphery of the presser foot tube c3, a tray rack c7 connected to the tray tube c6, and a tray driving mechanism for driving the tray tube c6 to rotate, which comprises a tray driving motor c8.1. The tray rack c7 is used to mount a tray with a rope belt (a belt-shaped object such as a belt and / or a rope). The tray generally has two. The tray tube c6 is rotatably sleeved on the outer periphery of the presser foot tube c3, and the tray tube c6 is a sleeve structure sleeved on the outer periphery of the fixed sleeve and can rotate around the presser foot tube c3 as the central axis. The tray tube c6 can be rotatably connected to the disc band embroidery machine shell c1, or can be rotatably connected to a support structure independently provided on the disc band embroidery machine shell c1 and fixed to the beam a.

[0061] For the flat embroidery machine head b:

[0062] The flat embroidery machine head b mainly comprises a flat embroidery machine shell b1 connected to the beam a, and a flat embroidery needle bar frame b2 capable of moving on the flat embroidery machine shell b1 and provided with a plurality of flat embroidery needle bars. Generally, the flat embroidery needle bar frame b2 is mainly slidably installed on the flat embroidery machine shell b1 through a slide rail structure, and is provided with a slide driving device (such as a push rod motor, a pneumatic cylinder, a pneumatic guide rail, etc.) connected with the flat embroidery needle bar frame b2 and driving the flat embroidery needle bar frame b2 to move; the slide driving device drives the flat embroidery needle bar frame b2 to move on the flat embroidery machine shell b1. The flat embroidery needle bar frame b2 is usually configured to move laterally on the flat embroidery machine shell b1, for example, the flat embroidery needle bar frame b2 is slidably installed on the flat embroidery machine shell b1 through a slide rail structure extending in the lateral direction to move in the lateral direction.

[0063] The mixed embroidery device can additionally provide a secondary shaft independent of the main shaft c9 to drive the flat embroidery needle bars installed on the flat embroidery needle bar frame b2 to perform embroidery actions. At this time, the secondary shaft is detachably connected with the flat embroidery needle bars through a flat embroidery needle bar driving connection structure (usually composed of a cam and a connecting rod mechanism), so that when the secondary shaft of the embroidery machine rotates, the flat embroidery needle bars can be driven to move up and down through the flat embroidery needle bar driving connection structure to perform embroidery actions.

[0064] Alternatively, the main shaft c9 also serves as the power shaft of the flat embroidery machine head b to drive the flat embroidery needle bars installed on the flat embroidery needle bar frame b2 to perform embroidery actions. At this time, the main shaft c9 is detachably connected with the flat embroidery needle bars through a flat embroidery needle bar driving connection structure (usually composed of a cam and a connecting rod mechanism), so that when the main shaft c9 of the embroidery machine rotates, the flat embroidery needle bars can be driven to move up and down through the flat embroidery needle bar driving connection structure to perform embroidery actions.

[0065] The flat embroidery needle bar frame b2 is provided with a plurality of flat embroidery needle bars arranged in the lateral direction. During embroidery, different flat embroidery needle bars are required according to the embroidery requirements, the flat embroidery needle bar frame b2 needs to be driven to slide so that the flat embroidery needle bar driving connection structure is connected with different flat embroidery needle bars to replace the flat embroidery needle bars required to perform embroidery actions, or the flat embroidery needle bar frame b2 is driven to slide to the empty position so that the flat embroidery needle bar driving connection structure is not connected with any flat embroidery needle bar to stop the flat embroidery machine head b from performing embroidery actions. The specific structure of the flat embroidery needle bar driving connection structure and the replacement structure and method of the flat embroidery needle bars are conventional settings of the flat embroidery machine head in the existing embroidery machine, and are not the improvement of the utility model, so they are not described in detail here.

[0066] At this time, based on the settings of the presser foot rotation driving motor c5.1 and the tray driving motor c8.1, and the movable setting of the flat embroidery needle bar frame b2, the head distance between the flat embroidery machine head and the disc tape embroidery machine head is easily increased, which further limits the number of machine heads installed and cannot form a mixed embroidery device with a larger embroidery scale.

[0067] Specifically: for example, see appendix Figure 1 As shown, when the flat embroidery head b and the ribbon embroidery head c are arranged adjacent to each other in the horizontal direction, the additional material tray drive motor c8.1, which is set up based on the independent drive requirement of the material tray tube c6, is easily placed between the flat embroidery machine housing b1 and the ribbon embroidery machine housing c1, occupying most of the space between them. This results in a need to leave more space between the flat embroidery machine housing b1 and the ribbon embroidery machine housing c1 to accommodate the material tray drive motor c8.1 and to allow the flat embroidery needle bar frame b2 to move. In other words, it easily leads to a larger head distance between the flat embroidery head b and the ribbon embroidery head c, which in turn limits the number of machine heads that can be installed, making it impossible to form a mixed embroidery device with a larger embroidery scale.

[0068] Based on this, in this embodiment, as shown in the appendix Figure 2 As shown, the tray drive output shaft c8.11 of the tray drive motor c8.1 is positioned between the main shaft c9 and the main beam a; that is, the tray drive output shaft c8.11 is positioned between the vertical plane containing the axis of the main shaft c9 (the axis that serves as the center when the main shaft c9 rotates) and the main beam a. By arranging the tray drive output shaft c8.11 and the flat embroidery needle holder b2 on the side of the main shaft c9 facing the main beam a and the side facing away from the main beam a, respectively, more space can be provided for the flat embroidery needle holder b2 to move on the side of the main shaft c9 facing away from the main beam a, reducing spatial interference. This allows the tray drive motor c8.1 to better accommodate the movement of the flat embroidery needle holder b2, reducing the space requirements between the flat embroidery head b and the ribbon embroidery head c. Consequently, the head distance between the flat embroidery head b and the ribbon embroidery head c can be reduced, allowing more heads to be installed in the mixed embroidery device, resulting in a larger and more extensive embroidery area.

[0069] In the above scheme, for the presser foot rotation drive mechanism:

[0070] As attached Figure 4 As shown, the presser foot rotation drive mechanism in this embodiment includes: a presser foot rotation drive motor c5.1, a presser foot rotation drive wheel c5.2, a presser foot rotation driven wheel c5.3, and a presser foot rotation transmission component c5.4.

[0071] The presser foot rotating driving motor c5.1 is a rotating motor connected to the beam a or the tambour embroidery machine shell c1 (usually connected to the tambour embroidery machine shell c1) and used to provide rotating power, and has a presser foot rotating driving shaft c5.11 extending vertically and used to output rotating power. A presser foot rotating driving wheel c5.2 is fixedly sleeved on the outer periphery of the presser foot rotating driving shaft c5.11. A presser foot rotating driven wheel c5.3 is sleeved on the outer periphery of the presser foot pipe c3 and connected to the presser foot pipe c3 (for example, connected by a key or a pin below). A presser foot rotating transmission member c5.4 is a transmission belt, a transmission chain, a transmission gear or a corresponding transmission structure for transmission connection between the presser foot rotating driving wheel c5.2 and the presser foot rotating driven wheel c5.3. When it is necessary to drive the presser foot pipe c3 to drive the presser foot connecting member c4 and the presser foot to rotate, the presser foot rotating driving motor c5.1 is used to drive the presser foot rotating driving shaft c5.11 to rotate, so as to drive the presser foot rotating driving wheel c5.2 to rotate and drive the presser foot rotating driven wheel c5.3 to rotate through the presser foot rotating transmission member c5.4, thereby driving the presser foot pipe c3 to rotate.

[0072] According to the length of the presser foot rotating driving shaft c5.11, one or more bearing structures for supporting the presser foot rotating driving shaft c5.11 can be connected to the tambour embroidery machine shell c1 or the beam a.

[0073] In order to stably rotate the presser foot pipe c3, the presser foot pipe c3 needs to be rotationally connected or the presser foot rotating driven wheel c5.3 needs to be rotationally connected. If the presser foot pipe c3 is rotationally connected to the tambour embroidery machine shell c1, an external force that is not needed and easily deviates the presser foot pipe c3 will be generated on the presser foot pipe c3 when the presser foot rotating driving mechanism is rotationally driven, thereby hindering the embroidery operation.

[0074] Therefore, in the embodiment, the presser foot rotating driven wheel c5.3 is preferably rotationally connected to ensure stable transmission and minimize the influence on the presser foot pipe c3.

[0075] As a rotational connection mode, the presser foot rotating driven wheel c5.3 is rotationally connected to the tambour embroidery machine shell c1. For example, the tambour embroidery machine shell c1 is fixedly connected with a positioning sleeve sleeved on the outer periphery of the presser foot pipe c3. The presser foot rotating driven wheel c5.3 has a part sleeved on the outer periphery of the positioning sleeve, and the part of the presser foot rotating driven wheel c5.3 is rotationally connected to the positioning sleeve, so that the presser foot rotating driven wheel c5.3 can rotate around the tambour embroidery needle bar c2 as an axis.

[0076] Furthermore, for the presser foot tube c3, it is also necessary to adapt to the embroidery action by moving up and down to apply pressure or release pressure to the fabric. Based on the above-mentioned presser foot rotation drive mechanism, in this embodiment, the presser foot rotation driven wheel c5.3 is connected to the presser foot tube c3 by a key or pin; and the presser foot assembly also includes a presser foot lifting drive mechanism connected to the presser foot tube c3 to drive the presser foot tube c3 to move up and down.

[0077] Specifically, either the presser foot tube c3 or the presser foot rotating driven wheel c5.3 is provided with a vertically extending slot, and the other is provided with a locking block inserted into the slot, so that: the presser foot rotating driven wheel c5.3 can drive the presser foot tube c3 to rotate synchronously, and the presser foot lifting drive mechanism can also drive the presser foot tube c3 to move up and down. The extension path length of the slot is set according to the path length of the lifting movement of the presser foot tube c3.

[0078] In this embodiment, the outer surface of the presser foot tube c3 is provided with a strip groove extending vertically, and the inner surface of the presser foot rotation driven wheel c5.3 has a protrusion and a locking block inserted into the strip groove.

[0079] For the tray drive mechanism:

[0080] As attached Figure 4 As shown, the material tray drive mechanism in this embodiment includes: a material tray drive motor c8.1, a material tray drive wheel c8.2, a material tray driven wheel c8.3, and a material tray transmission component c8.4.

[0081] The material tray drive motor c8.1 is a rotary motor connected to the main beam a or the tape embroidery machine housing c1 (generally connected to the tape embroidery machine housing c1) and used to provide rotational power. It has a vertically extending material tray drive output shaft c8.11 for outputting rotational power. The material tray drive output shaft c8.11 is fixedly fitted with a material tray drive wheel c8.2. The material tray tube c6 is fitted with a material tray driven wheel c8.3 on its outer periphery. The material tray driven wheel c8.3 is fixedly connected to the material tray tube c6 (this fixed connection means that the material tray driven wheel c8.3 is fixedly connected by auxiliary connecting parts such as screws or integrally formed with the material tray tube c6). The material tray transmission component c8.4 is a transmission belt, transmission chain, transmission gear or corresponding transmission structure that drives the material tray drive wheel c8.2 and the material tray driven wheel c8.3. So that when it is necessary to drive the material tray tube c6 to drive the material tray frame c7 to rotate, the material tray drive motor c8.1 drives the material tray drive output shaft c8.11 to rotate, which can drive the material tray drive wheel c8.2 to rotate, and through the material tray transmission component c8.4, drive the material tray driven wheel c8.3 to rotate, thereby driving the material tray tube c6 to rotate.

[0082] Depending on the length of the material tray drive output shaft c8.11, one or more bearing structures that support the material tray drive output shaft c8.11 can be connected to the embroidery machine housing c1 or the main beam a.

[0083] The presser foot driven wheel c5.3 is placed inside the tape embroidery machine housing c1, and the material tray driven wheel c8.3 is located below the presser foot driven wheel c5.3 and outside the tape embroidery machine housing c1.

[0084] Furthermore, the presser foot assembly also includes: a presser foot lifting drive mechanism connected to the presser foot tube c3 and driving the presser foot tube c3 to move up and down; the presser foot lifting drive mechanism includes: a presser foot lifting drive motor c10.1 for providing lifting power; the presser foot lifting drive motor c10.1 has a presser foot lifting drive shaft c10.11 that extends laterally and is used to output rotational power, and the axis of the presser foot lifting drive shaft c10.11 is located between the vertical plane where the axis of the main shaft c9 is located and the main beam a, so that when the axis of the presser foot lifting drive shaft c10.11 and the axis of the main shaft c9 are both projected onto the same horizontal plane, the axis of the presser foot lifting drive shaft c10.11 is located between the axis of the main shaft c9 and the main beam a.

[0085] By placing the axis of the presser foot lifting drive shaft c10.11 (the axis line that serves as the center when the presser foot lifting drive shaft c10.11 rotates) between the vertical plane where the axis of the main shaft c9 is located and the main beam a, based on the above scheme, more space can be provided on the side of the main shaft c9 facing away from the main beam a for the flat embroidery needle holder b2 to move, reducing spatial interference, making the head distance between the flat embroidery machine head b and the ribbon embroidery machine head c smaller, and more machine heads can be installed in the mixed embroidery device, with more and larger embroidery areas.

[0086] Furthermore, in this embodiment, as shown in the appendix Figure 2 and 3 As shown, the tray drive motor c8.1 and the presser foot lifting drive motor c10.1 are respectively located on the left and right sides of the ribbon embroidery machine housing c1. This optimized gravity distribution improves the stability of the embroidery installation while better avoiding an overly crowded design on one side and an overly spacious design on the other, making it easier to assemble and disassemble the tray drive motor c8.1 and the presser foot lifting drive motor c10.1.

[0087] To be precise, as shown in the appendix Figure 5 As shown, the presser foot lifting drive mechanism mainly includes: presser foot lifting drive motor c10.1, presser foot lifting drive wheel c10.2, presser foot lifting driven wheel c10.3, presser foot lifting transmission belt c10.4, presser foot drive component c10.6, and presser foot tube assembly c10.5.

[0088] The presser foot lifting drive motor c10.1 is a rotary motor connected to the main beam a or the tape embroidery machine housing c1 (generally connected to the tape embroidery machine housing c1) and used to provide rotational power. It has a presser foot lifting drive shaft c10.11 for outputting rotational power. The presser foot lifting drive shaft c10.11 is fixedly sleeved with a presser foot lifting drive wheel c10.2. One or more presser foot lifting driven wheels c10.3 are rotatably connected to the tape embroidery machine housing c1. The presser foot lifting drive wheel c10.2 and one or more presser foot lifting driven wheels c10.3 are connected by a presser foot lifting transmission belt c10.4, which is a transmission belt or a transmission chain. The presser foot lifting transmission belt c10.4 has a part that moves vertically. This part is fixedly connected to the presser foot drive component c10.6. The presser foot lifting drive motor c10.1 drives the presser foot lifting drive shaft c10.11 to rotate, which in turn drives the presser foot drive component c10.6 to move up and down.

[0089] Meanwhile, the outer periphery of the presser foot tube c3 is also provided with a presser foot tube assembly c10.5, which is fixedly connected to or integrally formed with the presser foot tube c3. The presser foot tube assembly c10.5 has a presser foot tube insertion groove c10.51 surrounding the presser foot tube c3 with the groove facing outward. The presser foot drive component c10.6 has a presser foot tube drive arm c10.61 adapted to be inserted into the presser foot tube insertion groove c10.51.

[0090] So that: the presser foot tube c3 can not only rotate synchronously with the driven wheel c5.3 rotating with the presser foot; it can also drive the presser foot drive component c10.6 to move up and down through the presser foot lifting drive motor c10.1, thereby driving the presser foot tube c3 to move up and down, and in turn driving the presser foot connected to the bottom of the presser foot tube c3 to move up and down according to the embroidery action.

[0091] Furthermore, the housing 1 may also be provided with a guide rod c10.7 extending vertically, and the pressure foot drive component c10.6 is slidably connected to the guide rod c10.7 and can slide up and down on the guide rod c10.7 to improve the stability of the lifting and lowering movement of the pressure foot sleeve 3.1.

[0092] Furthermore, to improve the stability of the lifting and lowering of the pressure foot tube C3 and reduce unnecessary tilting, as shown in the attached... Figure 5 As shown, by arranging the two presser foot lifting driven wheels c10.3 vertically, the part of the presser foot lifting transmission belt c10.4 that moves vertically in the vertical direction has: a vertically extending section; and a presser foot drive member c10.6 fixed to the vertically extending section of the presser foot lifting transmission belt c10.4.

[0093] On the basis of the above scheme, in order to make the rope belt on the tray rack c7 more stable and more suitable for the transmission of embroidery action; as shown in the accompanying Figure 4 and Figure 5 In this embodiment, a sleeve ring c11 that slides up and down on the tray pipe c6 is also provided on the outer periphery of the tray pipe c6. The sleeve ring c11 is connected to the tray pipe c6 by the key or pin connection, so that the sleeve ring c11 can rotate with the tray pipe c6 while also moving up and down on the tray pipe c6. For example, the outer surface of the tray pipe c6 is provided with a vertically extending strip-shaped groove, and the sleeve ring c11 is provided with a plug rod inserted into the strip-shaped groove.

[0094] The sleeve ring c11 is connected to a wire passing rack c12, which is provided with a wire passing hole c12.1 for the rope belt to pass through. When the embroidery action is performed, the rope belt on the tray rack c7 passes through the wire passing hole c12.1 to deliver the embroidery needle at the bottom of the tray belt embroidery needle rod c2. At the same time, the mixed embroidery device also includes a sleeve ring driving mechanism connected to the sleeve ring c11 and driving the sleeve ring c11 to move up and down. The sleeve ring driving mechanism includes a sleeve ring driving motor c13.1 for providing lifting power. The sleeve ring driving motor c13.1 has a sleeve ring driving output shaft c13.11 that extends transversely and is used to output rotary power. The axis of the sleeve ring driving output shaft c13.11 (the axis line that serves as the center when the sleeve ring driving output shaft c13.11 rotates) is located between the vertical plane where the main shaft c9 axis is located and the beam a, so that when the axis of the sleeve ring driving output shaft c13.11 and the main shaft c9 axis are both projected onto the same horizontal plane, the axis of the sleeve ring driving output shaft c13.11 is located between the main shaft c9 axis and the beam a.

[0095] By locating the axis of the sleeve ring driving output shaft c13.11 between the vertical plane where the main shaft c9 axis is located and the beam a, more space is provided on the side of the main shaft c9 away from the beam a for the flat embroidery needle rod rack b2 to move, reducing spatial interference and making the head distance between the flat embroidery head b and the tray belt embroidery head c smaller. More heads can be installed in the mixed embroidery device, and the embroidery area can be larger.

[0096] In this embodiment, as shown in the accompanying Figure 2 and 3 The sleeve ring driving motor c13.1 is also located on the side of the tray belt embroidery machine shell c1 away from the tray driving motor c8.1. The sleeve ring driving output shaft c13.11 and the presser foot lifting driving shaft c10.11, which both extend transversely, can be arranged without increasing the head distance.

[0097] In this configuration, the collar drive output shaft c13.11 is positioned above the main shaft c9, and the pressure foot lifting drive shaft c10.11 is positioned below the main shaft c9; alternatively, the collar drive output shaft c13.11 is positioned below the main shaft c9, and the pressure foot lifting drive shaft c10.11 is positioned above the main shaft c9. This optimizes the vertical distribution of the motors and improves the overall stability of the installation and connection on the main beam a.

[0098] Specifically, the collar drive mechanism mainly includes: collar drive motor c13.1, collar lifting drive wheel c13.2, collar lifting driven wheel c13.3, collar insertion groove c11.1, and collar drive rod c13.5.

[0099] The collar drive motor c13.1 is a rotary motor connected to the main beam a or the embroidery machine housing c1 (generally connected to the embroidery machine housing c1) to provide rotational power. It has a collar drive output shaft c13.11 for outputting rotational power. A collar lifting drive wheel c13.2 is fixedly sleeved on the outer circumference of the collar drive output shaft c13.11. One or more collar lifting driven wheels c13.3 are rotatably connected to the embroidery machine housing c1. The collar lifting drive wheel c13.2 and the one or more collar lifting driven wheels c13.3 are connected by a collar lifting transmission belt c13.4, which can be a transmission belt or a transmission chain. The collar lifting transmission belt c13.4 has a portion that moves vertically upwards and downwards.

[0100] A collar insertion slot c11.1 is provided on the collar c11. This collar insertion slot c11.1 is arranged around the material tray tube c6, and the slot opening faces outward. One end of the collar drive rod c13.5 is fixedly connected to a collar drive arm c13.51 adapted to be inserted into the collar insertion slot c11.1, and the other end is fixedly connected to a collar drive component c13.52. The collar drive component c13.52 is fixedly connected to the part of the collar lifting transmission belt c13.4 that moves vertically. By driving the collar drive output shaft c13.11 to rotate through the collar drive motor c13.1, the collar drive component c13.52 can be driven to move the collar c11 up and down.

[0101] As attached Figure 5 As shown, by arranging the two driven wheels c13.3 for lifting and lowering the collar in a vertical direction, the portion of the collar lifting transmission belt c13.4 that moves vertically in this direction includes: a vertically extending section; and a collar drive component c13.52 fixedly connected to the vertically extending section of the collar lifting transmission belt c13.4. This improves the stability of the collar c11's lifting and lowering, and reduces unnecessary tilting.
