Description

Technical Field

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

[0002] The tape embroidery machine head is a device used to embroider ribbons and / or ropes. It is generally composed of a housing, a drive spindle, a needle bar assembly, a feed assembly, a presser foot assembly, a thread take-up rod assembly, etc. The existing tape embroidery machine head drives the feed tray frame of the feed assembly and the presser foot mounting member of the presser foot assembly (on which the presser foot for wearing the belt and the nozzle for wearing the rope are installed. The presser foot described in this article is the auxiliary presser foot for wearing the belt in the tape embroidery, not the presser foot used in flat embroidery. The tape embroidery machine head is also equipped with a presser foot used in flat embroidery, but it is not shown in the figure and this article does not provide additional explanation here) to rotate synchronously. In order to increase the continuous working time of the tape embroidery, the existing feed assembly uses a large-sized feed tray to carry a large capacity of tape. As the size of the feed tray increases, the load also increases, and the tape embroidery machine head needs to run at high speed. When the feed tray and the presser foot mounting member rotate synchronously, the rotational inertia is large during rotation, and the feed tray is not easy to brake and turn around. Therefore, the rotation speed of the existing material tray is controlled at 600-700 rpm. During the operation of the tape embroidery machine head, the material tray rotates stiffly, the machine wears seriously, 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 the coiling embroidery due to the large size of the material tray during the synchronous rotation, and the control is more flexible, the mechanical wear is reduced, and the embroidery efficiency is improved. However, it is found in the actual use process that the embroidery accuracy of the above-mentioned coiling embroidery device needs to be improved, and the limitation of embroidery accuracy will affect the quality of the embroidery work.

[0024] The present invention is specifically described below with reference to the embodiments: Embodiment 1: The tape embroidery machine head is generally used to be installed on the embroidery machine frame 10, and is used to embroider embroidery threads (belts and / or ropes and other belt-like objects) into fabrics and other items to form embroidery works.

[0025] Existing tape embroidery machine head, such as the attached Figure 1 To Attachment Figure 5As shown, it mainly includes: a shell 1 for connecting to the embroidery machine frame 10 and for assembling various parts, a needle bar assembly for embroidering embroidery thread into fabric, a presser foot assembly for cooperating with the embroidery action to press and position the fabric, and a material tray assembly for placing embroidery thread (belts and / or ropes and other belt-like objects).

[0026] Among them, as attached Figure 1 As shown, the needle bar assembly mainly includes a needle bar 2 in a vertical axis structure, the needle bar 2 passes through the housing 10 in the vertical direction, and the lower end of the needle bar 2 passes through the housing 10 downward and is connected to an embroidery needle. At the same time, the needle bar assembly also includes a needle bar driving connection structure (generally composed of a cam and a connecting rod mechanism) that is transmission-connected to the needle bar 2. When the tape embroidery machine head is connected to the embroidery machine beam 10, the needle bar driving connection structure is transmission-connected to the main shaft of the embroidery machine, so that: when the main shaft of the embroidery machine rotates, the needle bar 2 can be driven to move up and down through the needle bar driving connection structure to perform embroidery actions.

[0027] Of course, the embroidery machine beam 10 is often connected to a plurality of tape embroidery machine heads. At this time, the needle bars 2 of the plurality of tape embroidery machine heads are often transmission-connected to the main shaft of the same embroidery machine, so that the main shaft of the embroidery machine can synchronously drive the plurality of tape embroidery machine heads to perform embroidery actions.

[0028] Among them, as attached Figure 1 As shown, the presser foot assembly mainly includes a presser foot tube 3.1 that is rotatably sleeved (sleeving in this application refers to: 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 needle bar 2, and the presser foot tube 3.1 is a sleeve structure that is sleeved on the periphery of the needle bar 2 and can rotate with the needle bar 2 as the central axis. The lower end of the presser foot tube 3.1 passes through the housing 10 downward and is connected to an auxiliary connector 3.2 for installing the presser foot; according to requirements, the auxiliary connector 3.2 can also be synchronously installed with other auxiliary assembly parts such as a nozzle and a rocker rod. The presser foot assembly also includes a presser foot rotation drive mechanism for driving the presser foot tube 3.1 to rotate (the specific structure of the presser foot rotation drive mechanism is described below).

[0029] The material tray assembly mainly includes a material tray tube 4.1 sleeved on the outer periphery of the presser foot tube 3.1, and a material tray frame connected to the material tray tube 4.1, the material tray frame is used to install a material tray with embroidery thread (belts and / or ropes and other belt-like objects), and the material tray is generally provided with two.

[0030] During the embroidery process, the presser foot tube 3.1 and the material coil tube 4.1 need to be driven to rotate to adapt to the embroidery action that needs to be constantly adjusted. If the material coil tube 4.1 is directly connected to the presser foot tube 3.1, problems such as mechanical wear during synchronous rotation and low embroidery efficiency will occur.

[0031] Based on this, the applicant previously applied for a tape embroidery device with publication number CN113584749B, which is driven and set separately by the material coil tube 4.1 and the presser foot tube 3.1, that is, a fixed sleeve is provided on the outer periphery of the presser foot tube 3.1, the material coil tube 4.1 is rotatably mounted on the outer periphery of the fixed sleeve, and a material coil driving mechanism for driving the material coil tube 4.1 to rotate is provided, and the fixed sleeve is connected to the shell 10, so as to solve the problem that the material coil size is too large to meet the high-speed operation of tape embroidery during the synchronous rotation of the existing material coil rack and the presser foot mounting part, the control is more flexible, the mechanical wear is reduced, and the embroidery efficiency is improved.

[0032] In the above scheme, the material coil 4.1 needs to be sleeved not only on the outer periphery of the presser foot tube 3.1, but also on the outer periphery of the fixed sleeve, which requires a larger volume of the material coil 4.1, resulting in the need to set the diameter and volume of the material coil 4.1 to be larger. At this time, when the material coil 4.1 is driven to rotate, the material coil 4.1 still has a large rotational inertia when rotating at high speed, resulting in a certain deviation in its rotation control accuracy.

[0033] Based on this, in order to further optimize the above-mentioned embroidery precision problem, the present application mainly improves the connection structure of the material coil 4.1 to form a new coiling embroidery machine head, specifically: As attached Figure 1 As shown, the material coil 4.1 in the present application is rotatably sleeved on the outer periphery of the presser foot tube 3.1, and the material coil 4.1 is a sleeve structure sleeved on the outer periphery of the fixed sleeve and can rotate with the presser foot tube 3.1 as the central axis. The outer periphery of the material coil 4.1 is sleeved with a rotating connection mechanism that allows the material coil 4.1 to be rotatably connected to the housing 1.

[0034] For rotating joints: In one form, the rotating connection mechanism can be a sleeve that is sleeved on the outer periphery of the material coil 4.1, the outer ring of the sleeve is fixedly connected to the shell 1, and the inner periphery is in contact with the material coil 4.1; at the same time, the sleeve is provided with a limiting structure that prevents the material coil 4.1 from detaching from the sleeve, so that the material coil 4.1 can be rotatably connected to the shell 1 through the rotating connection mechanism of the sleeve structure.

[0035] Alternatively, in another form, the rotating connection mechanism is: a bearing 8 sleeved on the outer periphery of the material coil tube 4.1; the outer ring of the bearing 8 is fixedly connected to the shell 1, and the inner ring is fixedly connected to the material coil tube 4.1, so that: the material coil tube 4.1 is rotationally connected to the shell 1 through the rotating connection mechanism of the bearing 8 structure.

[0036] For example, Figure 2 and attached Figure 3 As shown, the bottom of the shell 1 is provided with an insertion hole 1.2 for the needle rod 2 to be inserted, the upper end of the material coil tube 4.1 has a portion inserted upward into the insertion hole 1.2, the bearing 8 is installed in the insertion hole 1.2, and is sleeved on the outer periphery of the portion of the material coil tube 4.1 inserted into the insertion hole 1.2, and the outer ring of the bearing 8 is fixedly connected to the inner wall of the insertion hole 1.2, and the inner ring is fixedly connected to the portion of the material coil tube 4.1 inserted into the insertion hole 1.2, so that: the material coil tube 4.1 is rotatably connected to the shell 1 through the rotating connection mechanism of the bearing 8 structure.

[0037] In this way, the material coil 4.1 can be directly sleeved on the outer periphery of the presser foot tube 3.1 (that is, no additional sleeve structure can be provided between the material coil 4.1 and the presser foot tube 3.1) to realize the separate driving of the presser foot tube 3.1 and the material coil 4.1. That is, the volume requirement of the material coil 4.1 can be reduced (that is, while the presser foot tube 3.1 and the material coil 4.1 can be driven separately, the diameter of the material coil 4.1 can be set smaller, and then the material coil 4.1 as a whole can be set smaller), and the smaller material coil 4.1 can be driven more easily, reducing the rotation inertia of the material coil 4.1 when running at high speed, and improving the rotation control accuracy; and then: when the embroidery machine head is used for embroidery, the material coil frame and the thread material installed on the material coil frame can be rotated according to the rotation requirements with higher accuracy, so as to form a higher quality embroidery.

[0038] Furthermore, the inner wall of the material coil tube 4.1 and the outer wall of the presser foot tube 3.1 can be in contact with each other, but this can easily lead to interference in the rotation between the material coil tube 4.1 and the presser foot tube 3.1, affecting the rotation accuracy. Therefore, in this embodiment, the inner wall of the material coil tube 4.1 and the outer wall of the presser foot tube 3.1 are preferably arranged in a non-contact manner, so as to better avoid the rotation interference between the material coil tube 4.1 and the presser foot tube 3.1, so as to better improve the rotation control accuracy, and thus improve the embroidery accuracy.

[0039] At this time, in order to better improve the installation stability and rotation stability of the presser foot tube 3.1, as shown in the attached Figure 3 As shown, the outer periphery of the presser foot tube 3.1 is also sleeved with a positioning sleeve 1.1 located above the material coil tube 4.1; the positioning sleeve 1.1 is connected to the housing 1, and the inner periphery of the positioning sleeve 1.1 is in contact with the outer periphery of the presser foot tube 3.1. That is, when viewed from top to bottom, the inner periphery of the positioning sleeve 1.1 fits the outer periphery of the presser foot tube 3.1, so that the positioning sleeve 1.1 can position the relatively long presser foot tube 3.1, improve the overall installation accuracy, and the stability of the movement of the presser foot tube 3.1. The positioning sleeve 1.1 is preferably a shaft sleeve structure with good wear resistance.

[0040] The positioning sleeve 1.1 can be movably connected to the connecting portion 5.1, and the positioning sleeve 1.1 can rotate around the presser foot tube 3.1.

[0041] Alternatively, the positioning sleeve 1.1 is fixedly connected to the housing 1. For example, the positioning sleeve 1.1 is detachably fixedly connected to the housing 1 by means of screws, or the positioning sleeve 1.1 is non-detachably fixedly connected to the housing 1 by means of welding.

[0042] When the positioning sleeve 1.1 can be movably connected to the housing 1, although the above movement requirements can be met, the positioning sleeve 1.1 cannot provide relatively stable positioning support. Therefore, in this embodiment, the positioning sleeve 1.1 is preferably fixedly connected to the housing 1 to better improve the installation stability and rotation stability of the presser foot tube 3.1.

[0043] Based on 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 driving motor 3.3, a presser foot driving wheel 3.4, a presser foot driven wheel 3.5 and a presser foot transmission member 3.6.

[0044] The presser foot driving motor 3.3 is a rotary motor connected to the embroidery machine beam 10 or the housing 1 (generally connected to the housing 1) and used to provide rotational power, and has a presser foot driving motor driving shaft for outputting rotational power, and the presser foot driving motor driving shaft is fixedly sleeved with a presser foot driving wheel 3.4. The presser foot tube 3.1 is sleeved with a presser foot driven wheel 3.5, and the presser foot driven wheel 3.5 is connected to the presser foot tube 3.1 (for example, a key connection described below), and the presser foot transmission member 3.6 is a transmission belt or a transmission chain or a transmission gear or a corresponding transmission structure that transmits and connects the presser foot driving wheel 3.4 and the presser foot driven wheel 3.5. So that: when it is necessary to drive the presser foot tube 3.1 to drive the auxiliary connecting part 3.2 and the presser foot to rotate, the presser foot driving motor driving shaft is driven to rotate through the presser foot driving motor 3.3, which can drive the presser foot driving wheel 3.4 to rotate, and drive the presser foot driven wheel 3.5 to rotate through the presser foot transmission part 3.6, thereby driving the presser foot tube 3.1 to rotate.

[0045] According to the length of the driving shaft of the presser foot driving motor, one or more bearing structures for supporting the driving shaft of the presser foot driving motor may be connected to the housing 1 .

[0046] In order to make the presser foot tube 3.1 rotate stably, it is necessary to rotationally connect the presser foot tube 3.1 or rotationally connect the presser foot driven wheel 3.5; if the presser foot tube 3.1 is rotationally connected to the shell 1, when the presser foot rotation drive mechanism is rotationally driven, an unnecessary external force will be generated on the presser foot tube 3.1, which can easily pull the presser foot tube 3.1 off, resulting in obstruction of the embroidery action.

[0047] Based on this, in this embodiment, it is preferred to rotatably connect the presser foot driven wheel 3.5 to ensure stable transmission while minimizing the impact on the presser foot tube 3.1.

[0048] As a rotational connection, the presser foot driven wheel 3.5 is rotationally connected to the housing 1. Figure 3 As shown, the presser foot driven wheel 3.5 has a part which is sleeved on the outer periphery of the positioning sleeve 1.1, and the part of the presser foot driven wheel 3.5 is rotatably connected to the positioning sleeve 1.1, so that the presser foot driven wheel 3.5 can rotate with the needle bar 2 as the axis.

[0049] Furthermore, for the presser foot tube 3.1, 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 driven wheel 3.5 is key-connected to the presser foot tube 3.1; and the presser foot assembly also includes: a presser foot lifting drive mechanism connected to the presser foot tube 3.1 to drive the presser foot tube 3.1 to move up and down.

[0050] Specifically, one of the presser foot tube 3.1 and the presser foot driven wheel 3.5 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 driven wheel 3.5 can drive the presser foot tube 3.1 to rotate synchronously, and the presser foot lifting drive mechanism can also drive the presser foot tube 3.1 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 3.1.

[0051] In this embodiment, the outer surface of the presser foot tube 3.1 is provided with a strip groove extending in the vertical direction, and the inner surface of the presser foot driven wheel 3.5 has a protrusion and a block inserted into the strip groove.

[0052] And, if attached Figure 5 As shown, the presser foot lifting drive mechanism mainly includes: a lifting drive motor 7.1, a lifting driving wheel 7.2, a lifting driven wheel 7.3, a lifting transmission member 7.4, a driving member 7.5, an inserting part 7.51 and a follower connecting part 3.11. The lifting drive motor 7.1 is a rotary motor connected to the embroidery machine beam 10 or the housing 1 (generally connected to the housing 1) and used to provide rotational power. It has a lifting drive motor drive shaft for outputting rotational power. The lifting drive motor drive shaft is fixedly sleeved with a lifting driving wheel 7.2, and one or more lifting driven wheels 7.3 are rotatably connected to the housing 1. The lifting driving wheel 7.2 and the one or more lifting driven wheels 7.3 are connected to each other through a lifting transmission member 7.4, which is a transmission belt or a transmission chain. The lifting transmission member 7.4 has a part that is lifted and moved vertically, and the part is fixedly connected to a driving member 7.5. The lifting drive motor 7.1 drives the lifting drive motor drive shaft to rotate, so that the driving member 7.5 can be driven to move up and down.

[0053] At the same time, the outer periphery of the presser foot tube 3.1 is also provided with: a follower connection part 3.11 fixedly connected to the presser foot tube 3.1 or integrally formed with the presser foot tube 3.1, and the follower connection part 3.11 has a plug-in slot 3.12 arranged around the presser foot tube 3.1 and with the notch facing outward. The driving member 7.5 has a driving arm 7.51 adapted to be inserted into the plug-in slot 3.12.

[0054] So that: the presser foot tube 3.1 can not only rotate synchronously with the presser foot driven wheel 3.5, but also can drive the driving member 7.5 to move up and down through the lifting drive motor 7.1, so as to drive the presser foot tube 3.1 to move up and down, and then drive the presser foot connected to the bottom of the presser foot tube 3.1 to move up and down according to the embroidery action.

[0055] Furthermore, a guide rod 7.6 extending vertically may be provided in the housing 1, and the driving member 7.5 is slidably connected to the guide rod 7.6 and can slide up and down on the guide rod 7.6 to improve the stability of the lifting and lowering movement of the presser foot sleeve 3.1.

[0056] Based on the above solution, for the tray drive mechanism: As attached Figure 4 As shown, the tray driving mechanism in this embodiment includes: a tray driving motor 4.2, a tray driving wheel 4.3, a tray driven wheel 4.4 and a tray transmission member 4.5.

[0057] The tray drive motor 4.2 is a rotary motor connected to the embroidery machine beam 10 or the housing 1 (generally connected to the housing 1) and used to provide rotational power. It has a tray drive motor drive shaft for outputting rotational power, and the outer periphery of the tray drive motor drive shaft is fixedly sleeved with a tray driving wheel 4.3. The outer periphery of the tray tube 4.1 is sleeved with a tray driven wheel 4.4, and the tray driven wheel 4.4 is fixedly connected to the tray tube 4.1 (the fixed connection means that the tray driven wheel 4.4 is fixedly connected with the tray tube 4.1 by screws and other auxiliary parts or fixed with the tray tube 4.1 in an integral molding manner), and the tray transmission member 4.5 is a transmission belt or transmission chain or transmission gear or corresponding transmission structure that transmits and connects the tray driving wheel 4.3 and the tray driven wheel 4.4. So that: when it is necessary to drive the material tray tube 4.1 to drive the material tray frame to rotate, the material tray drive motor 4.2 drives the material tray drive motor drive shaft to rotate, which can drive the material tray driving wheel 4.3 to rotate, and drive the material tray driven wheel 4.4 to rotate through the material tray transmission member 4.5, thereby driving the material tray tube 4.1 to rotate.

[0058] According to the length of the driving shaft of the tray driving motor, one or more bearing structures for supporting the driving shaft of the tray driving motor may be connected to the housing 1 .

[0059] Embodiment 2: An embroidery machine comprises a coiled tape embroidery machine head in any of the solutions described in the first embodiment, and an embroidery machine beam 10, wherein a housing 1 of the coiled tape embroidery machine head is connected to the embroidery machine beam 10. The housing 1 can be detachably fixed to the embroidery machine beam 10 by, for example, a screw structure; or, in some environments that require special stability, the housing 1 can also be considered to be non-detachably connected to the embroidery machine beam 10 by, for example, welding.
