Description

Technical Field

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

[0002] The head device of the tape embroidery machine is a device used to embroider ribbons and / or ropes. It is generally composed of a housing, a driving spindle, a needle bar, a feed part, a presser foot part, a thread take-up bar part, etc. The existing head device of the tape embroidery machine drives the material tray frame of the feed part and the presser foot mounting part of the presser foot part (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 head device of the tape embroidery machine is also equipped with the 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 part 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, and the head device of the tape embroidery machine needs to operate at a 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. Therefore, the rotation speed of the existing material tray is controlled at 600-700 rpm. During the operation of the tape embroidery machine head device, 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 part, a presser foot part, and a material tray part; the needle bar of the needle bar part vertically passes through the casing, and the presser foot sleeve of the presser foot part is sleeved on the outside of 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 on the casing; the presser foot part includes a presser foot mounting part connected to the presser foot sleeve, and a presser foot rotation drive mechanism, and the presser foot mounting part 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 part 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, the mechanical wear is reduced, and the embroidery efficiency is improved. However, it is found in actual use that the convenience of disassembly and assembly of the above-mentioned coiling embroidery device needs to be improved. Summary of the invention

[0005] One of the purposes of the present invention is to address the deficiencies of the prior art and provide a tape embroidery machine head device that is more convenient to assemble and disassemble and has higher embroidery precision so as to optimize 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 device is generally used to be installed on the embroidery machine beam 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 device, such as the attached Figure 1 To Attachment Figure 5 As shown, it mainly includes: a casing 1 for connecting to an embroidery machine frame 10 and for assembling various parts, a needle bar for embroidering embroidery thread into fabric, a presser foot for cooperating with the embroidery action to press and position the fabric, and a material tray 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 part 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 part 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 device 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 head devices. At this time, the needle bars 2 of the plurality of tape embroidery head devices 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 head devices to perform embroidery actions.

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

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

[0030] During the embroidery process, the presser foot sleeve 3.1 and the material tray sleeve 4.1 need to be driven to rotate to adapt to the embroidery action that needs to be constantly adjusted. If the material tray sleeve 4.1 is directly connected to the presser foot sleeve 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 by separately setting the material tray sleeve 4.1 and the presser foot sleeve 3.1, that is, a fixed sleeve 6 is sleeved on the outer periphery of the presser foot sleeve 3.1, the material tray sleeve 4.1 is rotatably sleeved on the outer periphery of the fixed sleeve 6, and a material tray driving mechanism for driving the material tray sleeve 4.1 to rotate is provided, and the fixed sleeve 6 is connected to the casing 10, so as to solve the problem that the material tray size is too large to meet the high-speed operation of tape embroidery during the synchronous rotation of the existing material tray frame 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 three-layer sleeve structure formed by the presser foot sleeve 3.1, the fixed sleeve 6 and the material tray sleeve 4.1 are all connected to the casing 1. The casing 1 not only has a relatively narrow internal space, but also has many additional parts installed, such as the above-mentioned needle bar drive connection structure, etc., which leads to a large space limitation for the installation of the fixed sleeve 6 and the material tray sleeve 4.1. The installation of the fixed sleeve 6 and the material tray sleeve 4.1, as well as the subsequent disassembly and maintenance of the fixed sleeve 6 and the material tray sleeve 4.1 are very difficult.

[0033] Based on this, in order to further optimize the convenience of disassembly and assembly of the above-mentioned tape embroidery device, the present application mainly improves the fixed sleeve 6 and the material tray sleeve 4.1 to form a new tape embroidery machine head device, specifically: As attached Figure 1 As shown, the tape embroidery machine head device in the present application also includes: a beam support 5 that is independently arranged from the casing 1 and used to be connected to the embroidery machine beam 10, and the beam support 5 has a connecting portion 5.1 placed below the casing 1.

[0034] Moreover, the presser foot sleeve 3.1 in this embodiment is provided with a fixed sleeve 6 placed below the housing 1, and the material tray sleeve 4.1 is rotatably sleeved on the outer periphery of the fixed sleeve 6 (the specific rotatable sleeve structure can be selected from the existing conventional sleeve structures by those skilled in the art according to the description of this application, for example: the material tray sleeve 4.1 is sleeved on the outer periphery of the fixed sleeve 6, and the fixed sleeve 6 is provided with a first limiting structure to prevent the material tray sleeve 4.1 from escaping upward from the fixed sleeve 6, and a second limiting structure to prevent the material tray sleeve 4.1 from escaping downward from the fixed sleeve 6); the material tray sleeve 4.1 is a sleeve structure that is sleeved on the outer periphery of the fixed sleeve 6 and can rotate with the fixed sleeve 6 as the central axis. At the same time, the fixed sleeve 6 is connected to the connecting portion 5.1.

[0035] In this way, by setting up the beam bracket 5, and connecting the three-layer sleeve structure formed by the presser foot sleeve 3.1, the fixed sleeve 6 and the material tray sleeve 4.1 to the connecting part 5.1 of the beam bracket 5 located below the casing 1, relative to the narrow space of the casing 1, the fixed sleeve 6 and the material tray sleeve 4.1 have a relatively larger installation / disassembly space, so as to improve the convenience of disassembly and assembly of the fixed sleeve 6 and the material tray sleeve 4.1, thereby improving the convenience of disassembly and assembly of the tape embroidery machine head device.

[0036] At the same time, for the coiling embroidery machine head device, there are certain requirements for the position of the housing 1 and the position of the material tray sleeve 4.1 connected to the material tray frame, which cannot be too high or too low; thus, higher requirements are also put forward for the size of the material tray sleeve 4.1. When a coiling embroidery device such as the one with the publication number CN113584749B has a fixed sleeve 6 connected to the housing 1 and the material tray sleeve 4.1 is sleeved on the fixed sleeve 6, the lower end of the material tray sleeve 4.1 needs to extend to the installation position of the material tray frame, and the upper end needs to be close to or even inserted into the housing 1, resulting in the material tray sleeve 4.1 needing to be relatively long, and thus requiring a larger volume for the material tray sleeve 4.1.

[0037] In the present application, by connecting the fixed sleeve 6 to the connection part 5.1 of the beam support 5 below the casing 1, and making the material tray sleeve 4.1 sleeved on the outer periphery of the fixed sleeve 6, the upper end of the material tray sleeve 4.1 does not need to be close to or even inserted into the casing 1, and the upper end of the material tray sleeve 4.1 only needs to extend to the position of the connection part 5.1 below the casing 1. That is, the volume requirement for the material tray sleeve 4.1 can be reduced (that is, while the presser foot sleeve 3.1 and the material tray sleeve 4.1 can be driven separately, the material tray sleeve 4.1 can be set smaller), so that the material tray sleeve 4.1 can be driven more easily, the rotation inertia of the material tray sleeve 4.1 when running at high speed is reduced, and the rotation control accuracy is improved; furthermore, when the embroidery head device is used for embroidery, the material tray frame and the thread material installed on the material tray frame can be rotated according to the rotation requirements with higher accuracy, so as to form a higher quality embroidery.

[0038] The fixing sleeve 6 can be movably connected to the connecting portion 5.1, and the fixing sleeve 6 can rotate around the presser foot sleeve 3.1.

[0039] Alternatively, the fixing sleeve 6 is fixedly connected to the connecting portion 5.1. For example, the fixing sleeve 6 is detachably fixedly connected to the connecting portion 5.1 by means of screws, or the fixing sleeve 6 is non-detachably fixedly connected to the connecting portion 5.1 by means of welding.

[0040] When the fixed sleeve 6 can be movably connected to the connecting portion 5.1, although the above movement requirements can be met, the fixed sleeve 6 cannot block the rotational interference between the presser foot sleeve 3.1 and the material tray sleeve 4.1, which easily causes rotational interference between the presser foot sleeve 3.1 and the material tray sleeve 4.1, thereby causing the problem of embroidery deviation. Therefore, in this embodiment, it is preferred that the fixed sleeve 6 is fixedly connected to the connecting portion 5.1 to better avoid interference between the presser foot sleeve 3.1 and the material tray sleeve 4.1.

[0041] Wherein, the fixing sleeve 6 is fixedly connected to the connecting portion 5.1: For example, as a connection method, such as Figure 2 and attached Figure 3 As shown, the connecting portion 5.1 has a portion adapted to extend to the needle bar 2, and the portion is provided with an insertion hole 5.11 for the needle bar 2 to be vertically inserted so that the needle bar 2 can move up and down. The fixing sleeve 6 is sleeved outside the presser foot sleeve 3.1, and at least one end of the fixing sleeve 6 is embedded in the insertion hole 5.11, so that the fixing sleeve 6 is fixedly connected to the connecting portion 5.1. At the same time, a connecting member such as a screw can also be additionally provided to fix the fixing sleeve 6 to the connecting portion 5.1.

[0042] As attached Figure 3 As shown in the figure, in this embodiment, the fixing sleeve 6 preferably has a portion extending downwardly out of the connecting portion 5.1, and the tray sleeve 4.1 is rotatably sleeved on the outer periphery of the fixing sleeve 6 to further reduce the volume requirement for the tray sleeve 4.1.

[0043] Alternatively, for example, as another connection method, the connection part 5.1 may not be provided with the insertion hole 5.11 while making way for the needle bar 2, the presser foot sleeve 3.1 and the material tray sleeve 4.1; in this case, the fixing sleeve 6 is not embedded in the connection part 5.1, but, for example, the flange structure on the outer periphery of the fixing sleeve 6 is fixed to the connection part 5.1 of the beam bracket 5 by means of screws, for example.

[0044] Furthermore, in the above scheme, the inner periphery of the fixed sleeve 6 and the outer periphery of the presser foot sleeve 3.1 can be spaced apart; or, the inner periphery of the fixed sleeve 6 and the outer periphery of the presser foot sleeve 3.1 are in contact and fit, that is, when viewed from top to bottom, the inner periphery of the fixed sleeve 6 and the outer periphery of the presser foot sleeve 3.1 fit together, so that the fixed sleeve 6 can position the relatively long presser foot sleeve 3.1, improve the overall installation accuracy, and the stability of the movement of the presser foot sleeve 3.1. At this time, the fixed sleeve 6 is preferably a shaft sleeve structure with good wear resistance.

[0045] Similarly, in order to improve the rotation stability, the inner periphery of the tray sleeve 4.1 can also be in contact with the outer periphery of the fixing sleeve 6.

[0046] Furthermore, in order to further improve the installation and movement stability of the presser foot sleeve 3.1, as shown in the attached Figure 3 As shown, the outer periphery of the presser foot sleeve 3.1 can also be sleeved with a positioning sleeve 1.1 connected to the housing 1, and the inner periphery of the positioning sleeve 1.1 contacts and cooperates with the outer periphery of the presser foot sleeve 3.1 to further improve the positioning effect of the presser foot sleeve 3.1 and improve the stability of the installation and movement of the presser foot sleeve 3.1.

[0047] 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 rotation motor 3.3, a first driving wheel 3.4, a first driven wheel 3.5 and a first transmission member 3.6.

[0048] The presser foot rotary 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. It has a presser foot rotary motor drive shaft for outputting rotational power, and the outer periphery of the presser foot rotary motor drive shaft is fixedly sleeved with a first driving wheel 3.4. The outer periphery of the presser foot sleeve 3.1 is sleeved with a first driven wheel 3.5, and the first driven wheel 3.5 is connected to the presser foot sleeve 3.1 (for example, the key connection below), and the first 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 first driving wheel 3.4 and the first driven wheel 3.5. When the presser foot sleeve 3.1 needs to be driven to drive the presser foot mounting member 3.2 and the presser foot to rotate, the presser foot rotary motor 3.3 drives the presser foot rotary motor drive shaft to rotate, which can drive the first driving wheel 3.4 to rotate, and the first transmission member 3.6 drives the first driven wheel 3.5 to rotate, and then drives the presser foot sleeve 3.1 to rotate.

[0049] According to the length of the driving shaft of the presser foot rotating motor, one or more bearing structures for supporting the driving shaft of the presser foot rotating motor may be connected to the housing 1 .

[0050] In order to make the presser foot sleeve 3.1 rotate stably, it is necessary to rotationally connect the presser foot sleeve 3.1 or the first driven wheel 3.5; if the presser foot sleeve 3.1 is rotationally connected to the housing 1, when the presser foot rotary drive mechanism is rotationally driven, an unnecessary external force will be generated on the presser foot sleeve 3.1, which can easily pull the presser foot sleeve 3.1 off, resulting in obstruction of the embroidery action.

[0051] Based on this, in this embodiment, it is preferred that the first driven wheel 3.5 is rotationally connected to ensure stable transmission while minimizing the impact on the presser foot sleeve 3.1.

[0052] As a rotational connection mode, the first driven wheel 3.5 can be rotationally connected to the beam support 5. For example, the first driven wheel 3.5 is placed between the housing 1 and the connecting portion 5.1 of the beam support 5, and the lower end of the first driven wheel 3.5 is rotationally connected to the beam support 5, so that the first driven wheel 3.5 can rotate as described above.

[0053] As another rotational connection mode, the first driven wheel 3.5 is rotationally connected to the housing 1. Figure 3 As shown, the first driven wheel 3.5 has a portion sleeved on the outer periphery of the positioning sleeve 1.1, and the portion of the first driven wheel 3.5 is rotatably connected to the positioning sleeve 1.1, so that the first driven wheel 3.5 can rotate with the needle rod 2 as the axis.

[0054] At this time, the first driven wheel 3.5 can be placed inside the housing 1, or outside the housing 1 and between the connection part 5.1 of the housing 1 and the beam support 5. However, if the first driven wheel 3.5 is placed between the connection part 5.1 of the housing 1 and the beam support 5, the connection part 5.1, the fixing sleeve 6 and the material tray sleeve 4.1 will be forced to move downward, occupying too much embroidery space below, and the problem of embroidery interference will easily occur. Therefore, when the first driven wheel 3.5 is rotatably connected to the housing 1, the first driven wheel 3.5 is preferably placed inside the housing 1, which will not only prevent the connection part 5.1, the fixing sleeve 6 and the material tray sleeve 4.1 from moving downward, but also protect the driven wheel structure that is easily affected by dust and the like and reduces the smoothness of transmission.

[0055] Furthermore, for the presser foot sleeve 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 first driven wheel 3.5 is key-connected to the presser foot sleeve 3.1; and the presser foot part also includes: a presser foot lifting drive mechanism connected to the presser foot sleeve 3.1 to drive the presser foot sleeve 3.1 to move up and down.

[0056] Specifically, one of the presser foot sleeve 3.1 and the first 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 first driven wheel 3.5 can drive the presser foot sleeve 3.1 to rotate synchronously, and the presser foot lifting drive mechanism can also drive the presser foot sleeve 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 sleeve 3.1.

[0057] In this embodiment, the outer surface of the presser foot sleeve 3.1 is provided with a strip groove extending in the vertical direction, and the inner surface of the first driven wheel 3.5 has a protrusion and a block inserted into the strip groove.

[0058] 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.

[0059] At the same time, the outer periphery of the presser foot sleeve 3.1 is also provided with: a follower connection part 3.11 fixedly connected to the presser foot sleeve 3.1 or integrally formed with the presser foot sleeve 3.1, and the follower connection part 3.11 has an insertion groove 3.12 arranged around the presser foot sleeve 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 insertion groove 3.12.

[0060] So that: the presser foot sleeve 3.1 can not only rotate synchronously with the first 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 sleeve 3.1 to move up and down, and then drive the presser foot connected to the bottom of the presser foot sleeve 3.1 to move up and down according to the embroidery action.

[0061] 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.

[0062] 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 second driving wheel 4.3, a second driven wheel 4.4 and a second transmission member 4.5.

[0063] The tray drive motor 4.2 is a rotary motor connected to the embroidery machine frame 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 second driving wheel 4.3. The outer periphery of the tray sleeve 4.1 is sleeved with a second driven wheel 4.4, and the second driven wheel 4.4 is fixedly connected to the tray sleeve 4.1 (the fixed connection means that the second driven wheel 4.4 is fixedly connected with the tray sleeve 4.1 by a screw or other connecting member or is fixed with the tray sleeve 4.1 in an integral molding manner), and the second transmission member 4.5 is a transmission belt or a transmission chain or a transmission gear or a corresponding transmission structure that transmits and connects the second driving wheel 4.3 and the second driven wheel 4.4. So that: when it is necessary to drive the tray sleeve 4.1 to drive the tray frame to rotate, the tray drive motor 4.2 drives the tray drive motor drive shaft to rotate, which can drive the second driving wheel 4.3 to rotate, and drive the second driven wheel 4.4 to rotate through the second transmission member 4.5, thereby driving the tray sleeve 4.1 to rotate.

[0064] 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.
