Description

Technical Field

[0001] The present invention relates to the technical field of embroidery equipment, and more specifically to a mixed embroidery device and an embroidery machine. Background Art

[0002] The mixed embroidery device is a combined head device that has both a flat embroidery head and a tape embroidery head, so as to be able to perform flat embroidery and tape embroidery. Among them, the tape embroidery head is generally composed of a housing, a driving spindle, a needle bar assembly, a feed assembly, a presser foot assembly, a thread take-up rod assembly, etc. The existing tape embroidery head drives the material tray frame of the feed assembly and the presser foot mounting member of the presser foot assembly (on which a presser foot for wearing a belt and a nozzle for wearing a rope are installed. The presser feet described in this article are all auxiliary presser feet for wearing belts in tape embroidery, not presser feet used in flat embroidery. The tape embroidery head is also equipped with a presser foot used in flat embroidery, but it is not shown in the figure and will not be further explained in this article) to rotate synchronously. In order to increase the continuous working time of tape embroidery, the existing feed assembly uses a large-sized material tray to carry a large capacity of tape. As the size of the material tray increases, the load also increases. The embroidery head needs to run at high speed. When the material tray and the presser foot mounting part rotate synchronously, the rotational inertia is large during rotation, and the material tray is not easy to brake and turn around. For this reason, the speed of the existing material tray is controlled at 600~700 rpm. During the operation of the embroidery head, the material tray rotates stiffly, the mechanical wear is serious, and the embroidery efficiency is reduced.

[0003] Based on this, the applicant previously applied for a tape embroidery device with publication number CN113584749B, which includes a casing, a needle bar assembly, a presser foot assembly, and a material tray part; the needle bar of the needle bar assembly vertically passes through the casing, and the presser foot sleeve of the presser foot assembly is sleeved outside the needle bar; a fixed sleeve is outerly provided with an outer sleeve of the presser foot sleeve, and a shaft sleeve is outerly provided with the fixed sleeve, and the fixed sleeve is fixed to the casing; the presser foot assembly includes a presser foot mounting piece connected to the presser foot sleeve, and a presser foot rotation drive mechanism, and the presser foot mounting piece is used to install the presser foot and the nozzle; the material tray part includes a material tray frame and a material tray driving mechanism; the material tray driving mechanism drives the shaft sleeve to rotate, so as to drive the material tray frame to rotate; the presser foot rotation drive mechanism drives the presser foot sleeve to rotate, so as to drive the presser foot mounting piece to rotate.

[0004] The above-mentioned coiling embroidery device solves the problem that the existing material tray frame and the presser foot mounting member cannot meet the high-speed operation of coiling embroidery due to the large size of the material tray during the synchronous rotation, and the control is more flexible, reduces mechanical wear, and improves embroidery efficiency. However, when it is applied to a mixed embroidery device, it is easy to cause the head distance between the flat embroidery machine head and the coiling embroidery machine head to become larger, which in turn limits the number of machine heads installed and cannot form a mixed embroidery device with a larger embroidery scale.

[0024] The present invention is specifically described below with reference to the embodiments: Embodiment 1: Mixed embroidery device, such as the attached Figure 1As shown in the figure, it mainly includes a horizontally extending beam a, and a flat embroidery machine head b and a tape embroidery machine head c connected to the beam a. The mixed embroidery device also includes a main shaft c9 extending in the horizontal direction and driving the tape embroidery needle bar c2 to perform embroidery, the main shaft c9 passes through the flat embroidery machine head b, and has a part placed between the flat embroidery needle bar frame b2 and the beam a.

[0025] At least one flat embroidery machine head b and at least one tape embroidery machine head c are respectively provided, and each of the flat embroidery machine head b and the tape embroidery machine head c are fixedly connected to the beam a by, for example, screws, and the flat embroidery machine head b and the tape embroidery machine head c are arranged adjacent to each other in the horizontal direction. Of course, a plurality of flat embroidery machine heads b and a plurality of tape embroidery machine heads c can also be additionally provided, and the plurality of flat embroidery machine heads b and the plurality of tape embroidery machine heads c are arranged alternately in the horizontal direction (as shown in the attached figure). Figure 1 As shown, one flat embroidery head b and one tape embroidery head c are arranged); or multiple flat embroidery heads b and multiple tape embroidery heads c can also be arranged randomly in the horizontal direction according to embroidery requirements.

[0026] Among them, for the tape embroidery machine head c: As attached Figure 2 To Attachment 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 cord into the fabric, a presser foot assembly for cooperating with the embroidery action to press and position the fabric, and a material tray assembly for placing the cord (belts and / or ropes and other belt-like objects).

[0027] Among them, as attached Figure 2 As shown, the needle bar assembly mainly includes a tape embroidery needle bar c2 in a vertical axis structure, the tape embroidery needle bar c2 passes through the tape embroidery machine housing c10 in the vertical direction, and the lower end of the tape embroidery needle bar c2 passes through the tape embroidery machine housing c10 downward and is connected to an embroidery needle. At the same time, the needle bar assembly also includes a tape embroidery needle bar drive connection structure (generally composed of a cam and a connecting rod mechanism) that is transmission-connected to the tape embroidery needle bar c2. When the tape embroidery machine head c is connected to the beam a, the tape embroidery needle bar drive connection structure is transmission-connected to the main shaft c9 of the embroidery machine, so that: when the main shaft c9 of the embroidery machine rotates, the tape embroidery needle bar drive connection structure can drive the tape embroidery needle bar c2 to move up and down to perform embroidery actions.

[0028] The presser foot assembly mainly includes a presser foot tube c3 that is rotatably sleeved (sleeving in this application means: direct sleeve, that is, the sleeve part and the sleeved part are directly opposite to each other, and there is no other component placed between the sleeve part and the sleeved part; or indirect sleeve, that is, other components are sleeved on the periphery of the sleeved part, and the sleeve part is sleeved on the periphery of the sleeved part by being sleeved on the periphery of the component) on the periphery of the coiled embroidery needle rod c2. The presser foot tube c3 is a sleeve structure that is sleeved on the periphery of the coiled embroidery needle rod c2 and can rotate with the coiled embroidery needle rod c2 as the central axis. The lower end of the presser foot tube c3 passes through the coiled embroidery machine housing c10 downward and is connected to a presser foot connector c4 for installing the presser foot; according to requirements, the presser foot connector c4 can also be synchronously installed with other auxiliary assembly parts such as a nozzle and a swing rod. The presser foot assembly also includes a presser foot rotation driving mechanism for driving the presser foot tube c3 to rotate, and the presser foot rotation driving mechanism includes a presser foot rotation driving motor c5.1.

[0029] The material tray assembly mainly includes a material tray tube c6 sleeved on the outer periphery of the presser foot tube c3, a material tray frame c7 connected to the material tray tube c6, and a material tray driving mechanism for driving the material tray tube c6 to rotate, and the material tray driving mechanism includes a material tray driving motor c8.1. The material tray frame c7 is used to install a material tray with a rope (belt and / or rope and other belt-like objects), and the material tray is generally provided with two. The material tray tube c6 is rotatably sleeved on the outer periphery of the presser foot tube c3. The material tray tube c6 is a sleeve structure sleeved on the outer periphery of the fixed sleeve and can rotate with the presser foot tube c3 as the central axis. The material tray tube c6 can be rotatably connected to the tape embroidery machine housing c1, and can also be rotatably connected to the bracket structure provided on the independent tape embroidery machine housing c1 and fixed to the beam a.

[0030] For flat embroidery machine head b: The flat embroidery machine head b mainly includes: a flat embroidery machine housing b1 connected to the main beam a, and a flat embroidery needle bar frame b2 which can move on the flat embroidery machine housing b1 and is equipped with a plurality of flat embroidery needle bars. Generally speaking, the flat embroidery needle bar frame b2 is mainly slidably installed on the flat embroidery machine housing b1 through a slide rail structure, and is provided with a sliding drive device (such as a push rod motor, a cylinder, a pneumatic guide rail, etc.) connected to the flat embroidery needle bar frame b2 and driving it to move; the sliding drive device is used to drive the flat embroidery needle bar frame b2 to move on the flat embroidery machine housing b1. The flat embroidery needle bar frame b2 is usually configured to be able to move laterally on the flat embroidery machine housing b1, for example, the flat embroidery needle bar frame b2 is slidably installed on the flat embroidery machine housing b1 through a slide rail structure extending in the horizontal direction, so as to be able to move in the horizontal direction.

[0031] The mixed embroidery device can be additionally provided with a secondary shaft independent of the main shaft c9 to drive the flat embroidery needle bar installed on the flat embroidery needle bar frame b2 to perform embroidery. At this time, the secondary shaft is detachably connected to the flat embroidery needle bar through a flat embroidery needle bar driving connection structure (generally composed of a cam and a connecting rod mechanism), so that when the secondary shaft of the embroidery machine rotates, the flat embroidery needle bar can be driven to move up and down through the flat embroidery needle bar driving connection structure to perform embroidery.

[0032] Alternatively, the main shaft c9 also serves as the power shaft of the flat embroidery machine head b for embroidery action, to drive the flat embroidery needle bar installed on the flat embroidery needle bar frame b2 to perform embroidery action. At this time, the main shaft c9 is detachably connected to the flat embroidery needle bar through the flat embroidery needle bar driving connection structure (generally 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 bar can be driven to move up and down through the flat embroidery needle bar driving connection structure to perform embroidery action.

[0033] The flat embroidery needle bar frame b2 is provided with a plurality of flat embroidery needle bars arranged in a horizontal direction. During the embroidery process, according to the different flat embroidery needle bars required for embroidery, it is necessary to drive the flat embroidery needle bar frame b2 to slide so that the flat embroidery needle bar driving connection structure is connected to different flat embroidery needle bars to replace the flat embroidery needle bars that need to be embroidered; or drive the flat embroidery needle bar frame b2 to slide to an empty position so that the flat embroidery needle bar driving connection structure is not connected to any flat embroidery needle bar, so that the flat embroidery machine head b stops embroidery. Among them, the specific structure of the flat embroidery needle bar driving connection structure and the replacement structure and replacement method of the flat embroidery needle bar are all conventional setting structures of the flat embroidery machine head in the existing embroidery machine, and are not the improved invention points of this application, so they will not be described in detail here.

[0034] At this time, based on the settings of the presser foot rotation drive motor c5.1 and the material tray drive motor c8.1, as well as the movable setting of the flat embroidery needle bar rack b2, it is easy to cause the head distance between the flat embroidery machine head and the tape embroidery machine head to become larger, which in turn leads to a limit on the number of machine heads installed, and it is impossible to form a mixed embroidery device with a larger embroidery scale.

[0035] Specific: For example, Figure 1 As shown in the figure, when the flat embroidery machine head b and the tape embroidery machine head c are arranged adjacent to each other in the horizontal direction, the additional material tray drive motor c8.1 based on the independent drive requirement of the material coil tube c6 is easily placed between the flat embroidery machine housing b1 and the tape embroidery machine housing c1, and occupies most of the space between the flat embroidery machine housing b1 and the tape embroidery machine housing c1, which leads to the need to reserve a larger space between the flat embroidery machine housing b1 and the tape embroidery machine housing c1 to place the material tray drive motor c8.1 and for the flat embroidery needle bar frame b2 to move. That is, it is easy to cause the head distance between the flat embroidery machine head b and the tape embroidery machine head c to become larger, which leads to the limitation of the number of machine heads installed, and it is impossible to form a mixed embroidery device with a larger embroidery scale.

[0036] Based on this, in this embodiment, as shown in the attached Figure 2 As shown, the tray drive output shaft c8.11 of the tray drive motor c8.1 is placed between the main shaft c9 and the beam a; that is, the tray drive output shaft c8.11 is placed between the vertical plane where the axis of the main shaft c9 (the axis center line as the center when the main shaft c9 rotates) is located and the beam a. By arranging the tray drive output shaft c8.11 and the flat embroidery needle bar frame b2 on the side of the main shaft c9 facing the beam a and the side facing away from the beam a respectively; more space for the flat embroidery needle bar frame b2 to move can be better flowed out on the side of the main shaft c9 facing away from the beam a, and the spatial interference can be reduced, so that the tray drive motor c8.1 can better give way to the movement of the flat embroidery needle bar frame b2, reduce the size requirement of the spacing between the flat embroidery machine head b and the tape embroidery machine head c, and thus make the head distance between the flat embroidery machine head b and the tape embroidery machine head c smaller, more machine heads can be installed in the mixed embroidery device, and more and larger embroidery areas can be provided.

[0037] In the above scheme, for the presser foot rotation drive mechanism: As attached Figure 4 As shown, the presser foot rotation driving mechanism in this embodiment includes: a presser foot rotation driving motor c5.1, a presser foot rotation driving wheel c5.2, a presser foot rotation driven wheel c5.3 and a presser foot rotation transmission member c5.4.

[0038] The presser foot rotation driving motor c5.1 is a rotary motor connected to the beam a or the coiling embroidery machine housing c1 (generally connected to the coiling embroidery machine housing c1) and used to provide rotational power. It has a presser foot rotation driving shaft c5.11 extending vertically and used to output rotational power. The presser foot rotation driving shaft c5.11 is fixedly sleeved with a presser foot rotation driving wheel c5.2 on its outer circumference. The presser foot tube c3 is sleeved with a presser foot rotation driven wheel c5.3 on its outer circumference. The presser foot rotation driven wheel c5.3 is connected to the presser foot tube c3 (for example, connected by a key or a pin as described below), and the presser foot rotation transmission member c5.4 is a transmission belt or a transmission chain or a transmission gear or a corresponding transmission structure that transmits and connects the presser foot rotation driving wheel c5.2 and the presser foot rotation driven wheel c5.3. So that: when it is necessary to drive the presser foot tube c3 to drive the presser foot connecting piece c4 and the presser foot to rotate, the presser foot rotation drive shaft c5.11 is driven to rotate through the presser foot rotation drive motor c5.1, which can drive the presser foot rotation active wheel c5.2 to rotate, and drive the presser foot rotation driven wheel c5.3 to rotate through the presser foot rotation transmission piece c5.4, thereby driving the presser foot tube c3 to rotate.

[0039] According to the length of the presser foot rotating drive shaft c5.11, one or more bearing structures for supporting the presser foot rotating drive shaft c5.11 may be connected to the tape embroidery machine housing c1 or the beam a.

[0040] In order to make the presser foot tube c3 rotate stably, it is necessary to rotationally connect the presser foot tube c3 or rotationally connect the presser foot driven wheel c5.3; if the presser foot tube c3 is rotationally connected to the tape embroidery machine housing c1, when the presser foot rotation driving mechanism is rotationally driven, an unnecessary external force will be generated on the presser foot tube c3, which can easily pull the presser foot tube c3 off-center, thereby hindering the embroidery action.

[0041] Based on this, in this embodiment, it is preferred to rotatably connect the presser foot rotation driven wheel c5.3 to ensure stable transmission while minimizing the impact on the presser foot tube c3.

[0042] As a rotational connection method, the presser foot rotating driven wheel c5.3 is rotationally connected to the tape embroidery machine housing c1. For example, the tape embroidery machine housing c1 is fixedly connected to a positioning sleeve sleeved on the outer periphery of the presser foot tube c3, and 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 with the tape embroidery needle rod c2 as the axis.

[0043] Furthermore, for the presser foot tube c3, it is also necessary to adapt to the embroidery action to move up and down to press or release the fabric. Based on the setting of 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 through 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.

[0044] Specifically, one of the presser foot tube c3 and the presser foot rotating driven wheel c5.3 is provided with a strip groove extending in the vertical direction, and the other is provided with a block inserted into the strip groove, 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 perform lifting motion. The extension path length of the strip groove is set according to the path length of the lifting motion of the presser foot tube c3.

[0045] In this embodiment, the outer surface of the presser foot tube c3 is provided with a strip groove extending in the vertical direction, and the inner surface of the presser foot rotating driven wheel c5.3 has a protrusion and a block inserted into the strip groove.

[0046] For the tray drive mechanism: As attached Figure 4 As shown, the tray driving mechanism in this embodiment includes: a tray driving motor c8.1, a tray driving wheel c8.2, a tray driven wheel c8.3 and a tray transmission member c8.4.

[0047] The tray drive motor c8.1 is a rotary motor connected to the beam a or the coil embroidery machine housing c1 (generally connected to the coil embroidery machine housing c1) and used to provide rotational power. It has a tray drive output shaft c8.11 extending vertically and used to output rotational power. The tray drive output shaft c8.11 is fixedly sleeved with a tray driving wheel c8.2 on its outer circumference. The tray tube c6 is sleeved with a tray driven wheel c8.3 on its outer circumference. The tray driven wheel c8.3 is fixedly connected to the tray tube c6 (the fixed connection means that the tray driven wheel c8.3 is fixedly connected with the tray tube c6 by screws and other auxiliary parts or fixed with the tray tube c6 in an integral molding manner), and the tray transmission member c8.4 is a transmission belt or transmission chain or transmission gear or corresponding transmission structure that transmits and connects the tray driving wheel c8.2 and the 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 output shaft c8.1 is driven to rotate through the material tray drive motor c8.1, which can drive the material tray active wheel c8.2 to rotate, and drive the material tray driven wheel c8.3 to rotate through the material tray transmission member c8.4, thereby driving the material tray tube c6 to rotate.

[0048] According to the length of the tray drive output shaft c8.11, one or more bearing structures for supporting the tray drive output shaft c8.11 can be connected to the tape embroidery machine housing c1 or the beam a.

[0049] The presser foot rotating 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 rotating driven wheel c5.3 and outside the tape embroidery machine housing c1.

[0050] 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 lift and lower; 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 placed between the vertical plane where the axis of the main shaft c9 is located and the 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 projected onto the same horizontal plane, the axis of the presser foot lifting drive shaft c10.11 is placed between the axis of the main shaft c9 and the beam a.

[0051] By placing the axis of the presser foot lifting drive shaft c10.11 (the axis center line serving 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 beam a, on the basis of the above scheme, more space can be further left on the side of the main shaft c9 facing away from the beam a for the flat embroidery needle bar rack b2 to move, thereby alleviating spatial interference and making the head distance between the flat embroidery machine head b and the tape embroidery machine head c smaller. More machine heads can be installed in the mixed embroidery device, providing more and larger embroidery areas.

[0052] Moreover, in this embodiment, as shown in the attached Figure 2 and 3 As shown, the material tray drive motor c8.1 and the presser foot lifting drive motor c10.1 are respectively arranged on the left and right sides of the tape embroidery machine housing c1. While optimizing the gravity distribution to improve the installed embroidery stability, it is better to avoid the setting that one side of the tape embroidery machine head c is too crowded and the other side is too spacious, and the material tray drive motor c8.1 and the presser foot lifting drive motor c10.1 can be more conveniently disassembled and assembled.

[0053] Specifically, Figure 5 As shown, the presser foot lifting drive mechanism mainly includes: a presser foot lifting drive motor c10.1, a presser foot lifting active wheel c10.2, a presser foot lifting driven wheel c10.3, a presser foot lifting transmission belt c10.4, a presser foot driving member c10.6 and a presser foot pipe kit c10.5.

[0054] Among them, the presser foot lifting drive motor c10.1 is a rotating motor connected to the 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 active wheel c10.2 on the outer periphery, and the tape embroidery machine housing c1 is rotatably connected with one or more presser foot lifting driven wheels c10.3. The presser foot lifting active wheel c10.2 and the one or more presser foot lifting driven wheels c10.3 are connected for transmission via a presser foot lifting transmission belt c10.4, and the presser foot lifting transmission belt c10.4 is a transmission belt or a transmission chain. The presser foot lifting transmission belt c10.4 has a part that can be lifted and lowered in the vertical direction, and the part is fixedly connected to the presser foot driving component c10.6. The presser foot lifting driving motor c10.1 drives the presser foot lifting driving shaft c10.11 to rotate, thereby driving the presser foot driving component c10.6 to be lifted and lowered.

[0055] At the same time, the outer periphery of the presser foot tube c3 is also provided with: a presser foot tube set c10.5 fixedly connected to the presser foot tube c3 or integrally formed with the presser foot tube c3, the presser foot tube set c10.5 having a presser foot tube plug-in groove c10.51 arranged around the presser foot tube c3 with the notch facing outwards. The presser foot driving member c10.6 has a presser foot tube driving arm c10.61 adapted to be inserted into the presser foot tube plug-in groove c10.51.

[0056] So that: the presser foot tube c3 can not only rotate synchronously with the presser foot rotating driven wheel c5.3; it can also drive the presser foot driving member c10.6 to move up and down through the presser foot lifting driving motor c10.1, thereby driving the presser foot tube c3 to move up and down, and then drive the presser foot connected to the bottom of the presser foot tube c3 to move up and down according to the embroidery action.

[0057] Furthermore, a guide rod c10.7 extending vertically may be provided in the housing 1, and the presser foot driving member 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 presser foot sleeve 3.1.

[0058] Furthermore, in order to improve the stability of the lifting and lowering of the presser foot tube c3 and reduce the occurrence of unnecessary tilting effects, as shown in the attached Figure 5 As shown, by arranging the two presser foot lifting driven wheels c10.3 in the vertical direction, the part of the presser foot lifting transmission belt c10.4 that moves up and down in the vertical direction has: a vertical extension section extending vertically; and a presser foot driving member c10.6 fixedly connected to the vertical extension section of the presser foot lifting transmission belt c10.4.

[0059] On the basis of the above scheme, in order to make the rope belt on the material tray rack c7 more stable and more suitable for the embroidery action to be transported; Figure 4 and attached Figure 5 As shown, in this embodiment, a sleeve c11 is sleeved on the outer periphery of the material coil c6 and is lifted and slid on the material coil c6. The sleeve c11 is connected to the material coil c6 by a key or a pin in the above-mentioned key or pin connection manner, so that the sleeve c11 can rotate with the material coil c6 and can also be lifted and moved on the material coil c6. For example, a vertically extending strip groove is provided on the outer surface of the material coil c6, and the sleeve c11 is provided with an insertion rod inserted into the strip groove.

[0060] The ring c11 is connected to a thread passing rack c12, which is provided with a thread passing hole c12.1 for the rope to pass through; when embroidery is performed, the rope on the material tray rack c7 passes through the thread passing hole c12.1 to be transported to the embroidery needle at the bottom of the embroidery needle rod c2. At the same time, the mixed embroidery device also includes: a loop driving mechanism connected to the loop c11 and driving the loop c11 to move up and down; the loop driving mechanism includes a loop driving motor c13.1 for providing lifting power; the loop driving motor c13.1 has a loop driving output shaft c13.11 that extends laterally and is used to output rotational power, and the axis of the loop driving output shaft c13.11 (the axis center line serving as the center when the loop driving output shaft c13.11 rotates) is placed between the vertical plane where the axis of the main shaft c9 is located and the beam a, so that when the axis of the loop driving output shaft c13.11 and the axis of the main shaft c9 are projected to the same horizontal plane, the axis of the loop driving output shaft c13.11 is placed between the axis of the main shaft c9 and the beam a.

[0061] By placing the axis of the ring-driven output shaft c13.11 between the vertical plane where the axis of the main shaft c9 is located and the beam a, on the basis of the above-mentioned scheme, more space can be further left on the side of the main shaft c9 facing away from the beam a for the flat embroidery needle bar frame b2 to move, thereby alleviating spatial interference and making the head distance between the flat embroidery machine head b and the tape embroidery machine head c smaller. More machine heads can be installed in the mixed embroidery device, providing more and larger embroidery areas.

[0062] Moreover, in this embodiment, as shown in the attached Figure 2 and 3 As shown, the collar drive motor c13.1 is also arranged on the side of the tape embroidery machine housing c1 facing away from the tray drive motor c8.1. The collar drive output shaft c13.11 and the presser foot lifting drive shaft c10.11, both extending laterally, can be arranged better without interference and without increasing the head-to-head distance.

[0063] The collar drive output shaft c13.11 is placed above the main shaft c9, and the presser foot lifting drive shaft c10.11 is placed below the main shaft c9; or the collar drive output shaft c13.11 is placed below the main shaft c9, and the presser foot lifting drive shaft c10.11 is placed above the main shaft c9. This can optimize the distribution of the motor in the vertical direction and improve the overall stability of the installation connection on the beam a.

[0064] Specifically, the collar driving mechanism mainly includes: a collar driving motor c13.1, a collar lifting driving wheel c13.2, a collar lifting driven wheel c13.3, a collar plug-in slot c11.1, and a collar driving rod c13.5.

[0065] The collar drive motor c13.1 is a rotary motor connected to the beam a or the coiling embroidery machine housing c1 (generally connected to the coiling embroidery machine housing c1) and used to provide rotational power. It has a collar drive output shaft c13.11 for outputting rotational power. The collar drive output shaft c13.11 is fixedly sleeved with a collar lifting driving wheel c13.2 on its outer periphery, and the coiling embroidery machine housing c1 is rotatably connected with one or more collar lifting driven wheels c13.3. The collar lifting driving wheel c13.2 and one or more collar lifting driven wheels c13.3 are connected to each other through a collar lifting transmission belt c13.4, which is a transmission belt or a transmission chain. The collar lifting transmission belt c13.4 has a portion that is lifted and moved vertically.

[0066] The collar plug-in slot c11.1 is arranged on the collar c11, and the collar plug-in slot c11.1 is arranged around the material coil c6, and the slot is facing outwards; one end of the collar drive rod c13.5 is fixedly connected with a collar drive arm c13.51 adapted to be inserted into the collar plug-in slot c11.1, and the other end is fixedly connected with a collar drive member c13.52, and the collar drive member c13.52 is fixedly connected to the part of the collar lifting transmission belt c13.4 that is lifted and lowered in the vertical direction. The collar drive motor c13.1 drives the collar drive output shaft c13.11 to rotate, so that the collar drive member c13.52 can be driven to drive the collar c11 to lift and lower.

[0067] As attached Figure 5 As shown, by arranging two collar lifting driven wheels c13.3 in the vertical direction, the collar lifting transmission belt c13.4 has a vertical extension section extending vertically in the vertical lifting and moving part; and the collar driving member c13.52 is fixedly connected to the vertical extension section of the collar lifting transmission belt c13.4. This can improve the lifting stability of the collar c11 and reduce the occurrence of unnecessary tilting effects.
