Description

TECHNICAL FIELD

[0001] The utility model relates to embroidery equipment technical field, more specifically discloses a disc belt embroidery machine head and embroidery machine. BACKGROUND

[0002] The disc belt embroidery machine head is a device for embroidering belt and / or rope and the like. It is generally composed 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 belt embroidery machine head rotates synchronously through a driving motor to drive the tray rack of the feeding assembly and the presser foot mounting member of the presser foot assembly (on which a presser foot for threading a belt and a nozzle for threading a rope are installed. The presser foot described in this document is an auxiliary presser foot for disc belt embroidery, and is not the presser foot used in flat embroidery. The presser foot used in flat embroidery is also installed in the disc belt embroidery machine head, but it is not shown in the figure, and this will not be described additionally in this document). In order to improve the continuous working time of disc belt embroidery, the existing feeding assembly uses a large-size tray to carry a large-capacity belt material. As the size of the tray increases, the load also increases, and the disc belt embroidery machine head needs to operate at high speed. When the tray and the presser foot mounting member rotate synchronously, the rotational inertia is large, and the tray is not easy to brake and turn around. Therefore, the speed of the existing tray is controlled at 600-700 rpm. During the operation of the disc belt embroidery machine head, the tray rotates stiffly, and the mechanical wear is serious, which reduces the embroidery efficiency.

[0003] Based on this, the applicant previously applied for a disc belt embroidery device with publication number CN113584749B, which includes a machine shell, a needle bar assembly, a presser foot assembly, and a tray part. 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. A fixing sleeve is sleeved outside the presser foot sleeve, and a shaft sleeve is sleeved outside the fixing sleeve. The fixing 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 tray part includes a tray rack and a tray driving mechanism. The tray driving mechanism drives the shaft sleeve to rotate to drive the tray 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 belt embroidery device solves the problem that the existing tray rack and presser foot mounting member cannot meet the high-speed operation of disc belt embroidery due to the excessive size of the tray during synchronous rotation, and controls more flexibly, reduces mechanical wear, and improves embroidery efficiency. However, it is found in actual use that the embroidery precision of the above-mentioned disc belt embroidery device needs to be improved, and the limitation of embroidery precision will affect the quality of the embroidery work.

[0035] Figure 5 This is a schematic diagram of the presser foot lifting drive mechanism. Detailed Implementation

[0036] The utility model will be specifically illustrated below by combining with the embodiments:

[0037] Embodiment one:

[0038] The disc tape embroidery machine head is generally used to be installed on the embroidery machine beam 10, and is used to embroider the embroidery thread (tape and / or rope and other belt-shaped objects) into the cloth and other objects to form embroidery.

[0039] The existing disc tape embroidery machine head, such as the attached Figure 1 to the attached Figure 5 As shown, mainly includes: the shell 1 used to be connected to the embroidery machine beam 10 and be equipped with various parts, the needle bar assembly used to embroider the embroidery thread into the cloth, the presser foot assembly used to cooperate with the embroidery action to press and position the cloth, and the tray assembly used to place the embroidery thread (tape and / or rope and other belt-shaped objects).

[0040] Among them, as shown in the attached Figure 1 The needle bar assembly mainly includes the needle bar 2 in the vertical shaft structure, which passes through the shell 10 in the vertical direction, and the lower end of the needle bar 2 passes out of the shell 10 downward and is connected with the embroidery needle. At the same time, the needle bar assembly also includes the needle bar driving connection structure (generally composed of cam, connecting rod mechanism) drivingly connected to the needle bar 2, which is drivingly connected with the main shaft of the embroidery machine when the disc tape embroidery machine head is connected to the embroidery machine beam 10, realizing 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 the embroidery action.

[0041] Of course, the embroidery machine beam 10 is often connected with multiple disc tape embroidery machine heads, at this time, the needle bars 2 of multiple disc tape embroidery machine heads are often drivingly connected to the same main shaft of the embroidery machine, so that the main shaft of the embroidery machine can synchronously drive multiple disc tape embroidery machine heads to perform the embroidery action.

[0042] Among them, as shown in the attached Figure 1 The presser foot assembly mainly includes the presser foot pipe 3.1 rotatably sleeved (in this application, the sleeve refers to: direct sleeve, that is, the sleeve piece and the sleeved piece are directly opposite, and no other components are placed between the sleeve piece and the sleeved piece; or indirect sleeve, that is, the outer periphery of the sleeved piece is sleeved with other components, and the sleeve piece is sleeved on the outer periphery of the component to realize the sleeve on the outer periphery of the sleeved piece) on the outer periphery of the needle bar 2. The presser foot pipe 3.1 is a sleeve structure sleeved on the outer periphery of the needle bar 2 and can rotate around the needle bar 2 as the center shaft. The lower end of the presser foot pipe 3.1 passes out of the shell 10 downward and is connected with the auxiliary connecting piece 3.2 for installing the presser foot; according to the requirement, the auxiliary connecting piece 3.2 can also be synchronously installed with the nozzle, the swing rod and other auxiliary assembly parts. The presser foot assembly also includes the presser foot rotation driving mechanism (the specific structure of the presser foot rotation driving mechanism is described below) for driving the presser foot pipe 3.1 to rotate.

[0043] The tray assembly mainly comprises a tray pipe 4.1 sleeved on the outer periphery of the presser pipe 3.1, and a tray frame connected to the tray pipe 4.1, which is used to install the tray with embroidery thread (belt and / or rope, etc.).

[0044] In the process of embroidery, it is necessary to drive the presser pipe 3.1 and the tray pipe 4.1 to rotate to adapt to the continuously adjusted embroidery action, and if the tray pipe 4.1 is directly connected to the presser pipe 3.1, the problems of mechanical wear and low embroidery efficiency caused by synchronous rotation will occur.

[0045] Therefore, the applicant previously applied for a disc belt embroidery device with publication number CN113584749B, which separately drives the tray pipe 4.1 and the presser pipe 3.1, that is, a fixed sleeve is sleeved on the outer periphery of the presser pipe 3.1, the tray pipe 4.1 is rotatably sleeved on the outer periphery of the fixed sleeve, and a tray driving mechanism for driving the tray pipe 4.1 to rotate is arranged, and the fixed sleeve is connected to the housing 10, so as to solve the problem that the existing tray frame and the presser mounting member cannot meet the high-speed operation of disc belt embroidery due to the large size of the tray, and the control is more flexible, the mechanical wear is reduced, and the embroidery efficiency is improved.

[0046] In the above-mentioned scheme, the tray pipe 4.1 needs to be sleeved on the outer periphery of the presser pipe 3.1 and the outer periphery of the fixed sleeve, so that the tray pipe 4.1 has a large volume requirement, resulting in that the caliber and volume of the tray pipe 4.1 need to be set larger. At this time, when driving the tray pipe 4.1 to rotate, the tray pipe 4.1 still has a large rotational inertia when rotating at high speed, resulting in that the rotational control precision of the tray pipe 4.1 still has a certain deviation.

[0047] Therefore, in order to further optimize the above-mentioned embroidery precision problem, the connection structure of the tray pipe 4.1 is improved in the present application to form a new disc belt embroidery machine head, specifically:

[0048] As shown in the accompanying drawings, Figure 1 The tray pipe 4.1 in the present application is rotatably sleeved on the outer periphery of the presser pipe 3.1, and the tray pipe 4.1 is a sleeve structure sleeved on the outer periphery of the fixed sleeve and can rotate around the presser pipe 3.1 as the center axis. The outer periphery of the tray pipe 4.1 is sleeved with a rotating connection mechanism for rotating the tray pipe 4.1 to the housing 1.

[0049] For the rotating connection mechanism:

[0050] In one form, the rotating connection mechanism can be a shaft sleeve that is sleeved on the outer periphery of the tray pipe 4.1, the outer ring of the shaft sleeve is fixedly connected to the shell 1, and the inner periphery is in contact with the tray pipe 4.1; at the same time, the shaft sleeve is provided with a limiting structure for preventing the tray pipe 4.1 from being separated from the shaft sleeve, so that the tray pipe 4.1 can be rotatably connected to the shell 1 through the rotating connection mechanism of the shaft sleeve structure.

[0051] Alternatively, in another form, the rotating connection mechanism is a bearing 8 that is sleeved on the outer periphery of the tray pipe 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 tray pipe 4.1, so that the tray pipe 4.1 is rotatably connected to the shell 1 through the rotating connection mechanism of the bearing 8 structure.

[0052] For example, as shown in the accompanying drawings Figure 2 and the accompanying drawings Figure 3 As shown, the bottom of the shell 1 is provided with a plug-in hole 1.2 for inserting the needle rod 2, the upper end of the tray pipe 4.1 has a portion inserted into the plug-in hole 1.2, the bearing 8 is installed in the plug-in hole 1.2 and is sleeved on the outer periphery of the portion of the tray pipe 4.1 inserted into the plug-in hole 1.2, and the outer ring of the bearing 8 is fixedly connected to the inner wall of the plug-in hole 1.2, and the inner ring is fixedly connected to the portion of the tray pipe 4.1 inserted into the plug-in hole 1.2, so that the tray pipe 4.1 is rotatably connected to the shell 1 through the rotating connection mechanism of the bearing 8 structure.

[0053] In this way, the tray pipe 4.1 can be directly sleeved on the outer periphery of the presser pipe 3.1 (that is, no additional sleeve structure can be provided between the tray pipe 4.1 and the presser pipe 3.1) to achieve the separate driving of the presser pipe 3.1 and the tray pipe 4.1. That is, the volume requirement of the tray pipe 4.1 can be reduced (that is, the diameter of the tray pipe 4.1 can be set smaller while achieving the separate driving of the presser pipe 3.1 and the tray pipe 4.1, and thus the tray pipe 4.1 as a whole can be set smaller), and the smaller tray pipe 4.1 can be driven more easily, reducing the rotational inertia when the tray pipe 4.1 runs at high speed, and improving the rotational control precision; and thus when embroidery is performed using the disc belt embroidery machine head, the tray rack and the thread mounted on the tray rack can be rotated with higher precision according to the rotational requirements, so as to form higher quality embroidery.

[0054] Further, the inner wall of the tray pipe 4.1 and the outer wall of the presser pipe 3.1 can be in contact, but this can easily cause rotation interference between the tray pipe 4.1 and the presser pipe 3.1, affecting the rotation precision. Therefore, in the present embodiment, the inner wall of the tray pipe 4.1 and the outer wall of the presser pipe 3.1 are preferably not in contact, so as to better avoid rotation interference between the tray pipe 4.1 and the presser pipe 3.1, so as to better improve the rotation control precision and thus improve the embroidery precision.

[0055] At this point, in order to better improve the installation stability and rotational stability of the pressure foot tube 3.1, as shown in the attached... Figure 3 As shown, a positioning sleeve 1.1 is also fitted around the outer periphery of the presser foot tube 3.1, located above the material tray tube 4.1. The positioning sleeve 1.1 is connected to the housing 1, and the inner periphery of the positioning sleeve 1.1 contacts and engages with the outer periphery of the presser foot tube 3.1. That is, viewed from above, the inner periphery of the positioning sleeve 1.1 fits snugly against the outer periphery of the presser foot tube 3.1. In this way, the positioning sleeve 1.1 can position the longer presser foot tube 3.1, improving 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 bushing structure with good wear resistance.

[0056] The positioning sleeve 1.1 can be movably connected to the connecting part 5.1, and the positioning sleeve 1.1 can rotate around the pressure foot tube 3.1.

[0057] Alternatively, the positioning sleeve 1.1 is fixedly connected to the housing 1. For example, the positioning sleeve 1.1 may be detachably fixedly connected to the housing 1 by means of a screw or similar structure, or the positioning sleeve 1.1 may be non-detachably fixedly connected to the housing 1 by means of welding or similar methods.

[0058] When the positioning sleeve 1.1 is movably connected to the housing 1, although the above-mentioned motion requirements can be met, the positioning sleeve 1.1 cannot provide stable positioning support. Therefore, in this embodiment, it is preferable to fix the positioning sleeve 1.1 to the housing 1 to better improve the installation stability and rotational stability of the pressure foot tube 3.1.

[0059] Based on the above solution, for the presser foot rotation drive mechanism:

[0060] As attached Figure 4 As shown, the presser foot rotation drive mechanism in this embodiment includes: a presser foot drive motor 3.3, a presser foot drive wheel 3.4, a presser foot driven wheel 3.5, and a presser foot transmission component 3.6.

[0061] The presser foot drive motor 3.3 is a rotary motor connected to the main beam 10 or housing 1 of the embroidery machine (generally connected to the housing 1) and used to provide rotational power. It has a presser foot drive motor drive shaft for outputting rotational power, and a presser foot drive wheel 3.4 is fixedly sleeved on the outer periphery of the presser foot drive motor drive shaft. A presser foot driven wheel 3.5 is sleeved on the outer periphery of the presser foot tube 3.1. The presser foot driven wheel 3.5 is connected to the presser foot tube 3.1 (e.g., a key connection as described below), and the presser foot transmission component 3.6 is a transmission belt, transmission chain, transmission gear, or corresponding transmission structure that drives the presser foot drive 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 piece 3.2 and the presser foot to rotate, the presser foot drive motor 3.3 drives the presser foot drive motor drive shaft to rotate, which can drive the presser foot drive wheel 3.4 to rotate, and drive the presser foot driven wheel 3.5 to rotate through the presser foot transmission piece 3.6, thereby driving the presser foot tube 3.1 to rotate.

[0062] Depending on the length of the presser foot drive motor drive shaft, one or more bearing structures that support the presser foot drive motor drive shaft can be connected to the housing 1.

[0063] In order for the presser foot tube 3.1 to rotate stably, it is necessary to rotatably connect the presser foot tube 3.1 or the presser foot driven wheel 3.5. However, if the presser foot tube 3.1 is rotatably connected to the housing 1, when the presser foot rotation drive mechanism rotates, it will generate an unnecessary external force on the presser foot tube 3.1, which is likely to pull the presser foot tube 3.1 off-center, thus hindering the embroidery action.

[0064] Therefore, in this embodiment, it is preferable to rotatably connect the pressure foot driven wheel 3.5 to ensure stable transmission while minimizing the impact on the pressure foot tube 3.1.

[0065] As a rotating connection, the pressure foot driven wheel 3.5 is rotatably connected to the housing 1. For example, see attached... Figure 3 As shown, the presser foot driven wheel 3.5 has a portion sleeved on the outer periphery of the positioning sleeve 1.1. This portion 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 about the needle bar 2 as an axis.

[0066] Furthermore, for the presser foot tube 3.1, it is also necessary to adapt to the embroidery action by moving up and down to apply pressure or release pressure on the fabric. Based on the above-mentioned presser foot rotation drive mechanism, in this embodiment, the presser foot driven wheel 3.5 is keyed 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.

[0067] Specifically, either the presser foot tube 3.1 or the presser foot driven wheel 3.5 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 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 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 3.1.

[0068] In this embodiment, the outer surface of the presser foot tube 3.1 is provided with a strip groove extending vertically, and the inner surface of the presser foot driven wheel 3.5 has a protrusion and a locking block inserted into the strip groove.

[0069] Furthermore, as attached Figure 5 As shown, the presser foot lifting drive mechanism mainly includes: a lifting drive motor 7.1, a lifting drive wheel 7.2, a lifting driven wheel 7.3, a lifting transmission component 7.4, a drive component 7.5, an inserting part 7.51, and a follower connecting part 3.11.

[0070] The lifting drive motor 7.1 is a rotary motor connected to the main beam 10 of the embroidery machine 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. A lifting drive wheel 7.2 is fixedly sleeved on the outer periphery of the lifting drive motor drive shaft, and one or more lifting driven wheels 7.3 are rotatably connected to the housing 1. The lifting drive wheel 7.2 and the one or more lifting driven wheels 7.3 are connected by a lifting transmission component 7.4, which is a transmission belt or a transmission chain. The lifting transmission component 7.4 has a part that moves vertically. This part is fixedly connected to a drive component 7.5. By driving the lifting drive motor drive shaft to rotate by the lifting drive motor 7.1, the drive component 7.5 can be driven to move up and down.

[0071] Meanwhile, the outer periphery of the presser foot tube 3.1 is also provided with a follower connection part 3.11 that is fixedly connected to or integrally formed with the presser foot tube 3.1. The follower connection part 3.11 has an insertion groove 3.12 that surrounds the presser foot tube 3.1 and faces outward. The drive member 7.5 has a drive arm 7.51 that is adapted to be inserted into the insertion groove 3.12.

[0072] So that: the presser foot tube 3.1 can not only rotate synchronously with the presser foot driven wheel 3.5; it can also drive the drive component 7.5 to move up and down through the lifting drive motor 7.1, thereby driving the presser foot tube 3.1 to move up and down, and then driving the presser foot connected to the bottom of the presser foot tube 3.1 to move up and down according to the embroidery action.

[0073] Further, the casing 1 can be further provided with a guide rod 7.6 extending in the vertical direction, and the driving member 7.5 is slidingly connected to the guide rod 7.6 and can slide up and down on the guide rod 7.6, so as to improve the stability of the lifting movement of the presser foot sleeve 3.1.

[0074] Based on the above scheme, for the tray driving mechanism:

[0075] As shown in the accompanying drawings, Figure 4 The tray driving mechanism in the 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.

[0076] The tray driving motor 4.2 is a rotating motor connected to the beam 10 or the casing 1 of the embroidery machine (usually connected to the casing 1) and used to provide rotating power. It has a tray driving motor drive shaft for outputting rotating power, and the outer periphery of the tray driving motor drive shaft is fixedly sleeved with the tray driving wheel 4.3. The outer periphery of the tray tube 4.1 is sleeved with the tray driven wheel 4.4, which is fixedly connected to the tray tube 4.1 (the fixed connection means that the tray driven wheel 4.4 is fixedly connected by a screw or other auxiliary connecting member or is integrally formed with the tray tube 4.1), and the tray transmission member 4.5 is a transmission belt, a transmission chain, a transmission gear, or a corresponding transmission structure for transmission connection between the tray driving wheel 4.3 and the tray driven wheel 4.4. When it is necessary to drive the tray tube 4.1 to rotate with the tray frame, the tray driving motor 4.2 drives the tray driving motor drive shaft to rotate, which can drive the tray driving wheel 4.3 to rotate, and the tray transmission member 4.5 drives the tray driven wheel 4.4 to rotate, thereby driving the tray tube 4.1 to rotate.

[0077] According to the length of the tray driving motor drive shaft, one or more bearing structures for supporting the tray driving motor drive shaft can be connected to the casing 1.

[0078] Embodiment two:

[0079] The embroidery machine includes the disc tape embroidery machine head of any of the schemes in Embodiment One and an embroidery machine beam 10, and the casing 1 of the disc tape embroidery machine head is connected to the embroidery machine beam 10. The casing 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 casing 1 can also be considered to be non-detachably connected to the embroidery machine beam 10 by, for example, welding.
