Description

TECHNICAL FIELD

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

[0002] Disc belt embroidery machine head device is the device for embroidering belt and / or rope and so on belt-shaped object. It is generally composed of casing, driving main shaft, needle bar part, feeding part, presser foot part, thread lifting lever part. The existing disc belt embroidery machine head device rotates synchronously through a driving motor to drive the tray frame of the feeding part, the presser foot mounting member of the presser foot part (a presser foot for threading a belt and a nozzle for threading a rope are installed on it, the presser foot described in this paper is an auxiliary presser foot for disc belt embroidery, and it does not refer to the presser foot used in flat embroidery, and the disc belt embroidery machine head device also installs the presser foot used in flat embroidery, but it is not shown in the figure, and this paper does not make additional description here). In order to improve the continuous working time of disc belt embroidery, the existing feeding part adopts a large-size tray to carry a large-capacity belt material. With the increase of the size of the tray, the load also increases, and the disc belt embroidery machine head device needs to run at high speed. When the tray and the presser foot mounting member rotate synchronously, the rotational inertia is large during rotation, 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 device, the tray rotates stiffly, the mechanical wear is serious, and the embroidery efficiency is reduced.

[0003] Based on this, the applicant previously applied for a disc belt embroidery device with publication number CN113584749B, which includes a casing, a needle bar part, a presser foot part, and a tray part. The needle bar of the needle bar part vertically penetrates the casing, and the presser foot sleeve of the presser foot part 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 casing. The presser foot part 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 frame and a tray driving mechanism. The tray driving mechanism drives the shaft sleeve to rotate to drive the tray frame 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 frame 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 disassembly and assembly convenience of the above-mentioned disc belt embroidery device needs to be improved. UTILITY MODEL CONTENTS

[0035] The utility model will be specifically illustrated below by combining with the embodiments:

[0036] Embodiment one:

[0037] The disc tape embroidery machine head device is generally 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.

[0038] The existing disc tape embroidery machine head device, such as the attached Figure 1 to the attached Figure 5 As shown, mainly includes: the machine shell 1 used to connect to the embroidery machine beam 10 and for the assembly of each part, the needle bar part used to embroider the embroidery thread into the cloth, the presser foot part used to cooperate with the embroidery action to press and position the cloth, and the tray part used to place the embroidery thread (tape and / or rope and other belt-shaped objects).

[0039] Among them, as shown in the attached Figure 1 The needle bar part mainly includes a needle bar 2 in vertical shaft structure, which passes through the machine shell 10 in the vertical direction, and the lower end of the needle bar 2 passes out of the machine shell 10 downward and is connected with the 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) drivingly connected to the needle bar 2, which is drivingly connected to the main shaft of the embroidery machine when the disc tape embroidery machine head device 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 by the needle bar driving connection structure to perform the embroidery action.

[0040] Of course, the embroidery machine beam 10 is often connected with multiple disc tape embroidery machine head devices, at this time, the needle bars 2 of multiple disc tape embroidery machine head devices 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 head devices to perform the embroidery action.

[0041] Among them, as shown in the attached Figure 1As shown, the presser foot part mainly comprises a presser foot sleeve 3.1 rotatably sleeved on the outer periphery of the needle bar 2, which 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 axis. The lower end of the presser foot sleeve 3.1 penetrates the shell 10 downward and is connected with a presser foot mounting member 3.2 for mounting the presser foot. According to requirements, the presser foot mounting member 3.2 can also be synchronously mounted with a nozzle, a swing rod and other auxiliary assembly members. The presser foot part further comprises a presser foot rotation driving mechanism for driving the presser foot sleeve 3.1 to rotate (the specific structure of the presser foot rotation driving mechanism will be described below).

[0042] The tray part mainly comprises a tray sleeve 4.1 sleeved on the outer periphery of the presser foot sleeve 3.1, and a tray rack connected to the tray sleeve 4.1, which is used to mount the tray with embroidery thread (belt and / or rope, etc.). The tray generally has two.

[0043] In the process of embroidery, the presser foot sleeve 3.1 and the tray sleeve 4.1 need to be driven to rotate to adapt to the continuously adjusted embroidery action. If the tray sleeve 4.1 is directly connected to the presser foot sleeve 3.1, the following problems will occur: mechanical wear during synchronous rotation and low embroidery efficiency.

[0044] Therefore, the applicant previously applied for a disc and belt embroidery device with publication number CN113584749B. The tray sleeve 4.1 and the presser foot sleeve 3.1 are driven separately, i.e., a fixed sleeve 6 is sleeved on the outer periphery of the presser foot sleeve 3.1, the tray sleeve 4.1 is rotatably sleeved on the outer periphery of the fixed sleeve 6, and a tray driving mechanism for driving the tray sleeve 4.1 to rotate is provided. The fixed sleeve 6 is connected to the shell 10 to solve the problem that the tray rack and the presser foot mounting member cannot be synchronously rotated at high speed 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.

[0045] In the above-mentioned scheme, the three-layer sleeving structure formed by the presser foot sleeve 3.1, the fixed sleeve 6 and the tray sleeve 4.1 is connected to the shell 1. The shell 1 has a relatively narrow internal space and is also installed with many additional parts, such as the above-mentioned needle bar driving connection structure, etc., resulting in that the installation of the fixed sleeve 6 and the tray sleeve 4.1 is greatly limited by space, and the installation of the fixed sleeve 6 and the tray sleeve 4.1, as well as the subsequent disassembly and maintenance of the fixed sleeve 6 and the tray sleeve 4.1 are very difficult.

[0046] Based on this, in order to further optimize the disassembly convenience of the above-mentioned disc tape embroidery device, the fixed sleeve 6 and the tray sleeve 4.1 are improved to form a new disc tape embroidery machine head device, specifically:

[0047] As shown in the accompanying Figure 1 The disc tape embroidery machine head device in the present application also includes a beam support 5 which is independent of the cabinet 1 and is connected to the embroidery machine beam 10, and the beam support 5 has a connecting part 5.1 placed below the cabinet 1.

[0048] In addition, the presser foot sleeve 3.1 in the present embodiment is provided with a fixed sleeve 6 placed below the cabinet 1, and the tray sleeve 4.1 is rotatably sleeved on the outer periphery of the fixed sleeve 6 (the specific rotatable sleeving structure can be selected by those skilled in the art according to the present application description from the existing conventional sleeving structure, for example: the 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 tray sleeve 4.1 from being separated upward from the fixed sleeve 6, and a second limiting structure to prevent the tray sleeve 4.1 from being separated downward from the fixed sleeve 6); the tray sleeve 4.1 is a sleeve structure sleeved on the outer periphery of the fixed sleeve 6 and can rotate around the fixed sleeve 6 as the center axis. At the same time, the fixed sleeve 6 is connected to the connecting part 5.1.

[0049] In this way, by setting the beam support 5 and connecting the three-layer sleeving structure formed by the presser foot sleeve 3.1, the fixed sleeve 6 and the tray sleeve 4.1 to the connecting part 5.1 of the beam support 5 located below the cabinet 1, the fixed sleeve 6 and the tray sleeve 4.1 have relatively larger installation / dismounting space relative to the narrow space of the cabinet 1, so as to improve the disassembly convenience of the fixed sleeve 6 and the tray sleeve 4.1, and further improve the disassembly convenience of the disc tape embroidery machine head device.

[0050] At the same time, for the disc tape embroidery machine head device, the position of the cabinet 1 and the position of the tray holder connected to the tray sleeve 4.1 both have certain requirements, which cannot be too high or too low; and higher requirements are also put forward for the size of the tray sleeve 4.1. When the fixed sleeve 6 is connected to the cabinet 1 and the tray sleeve 4.1 is sleeved on the fixed sleeve 6 as disclosed in the publication No. CN113584749B, the lower end position of the tray sleeve 4.1 needs to extend to the installation position of the tray holder, and the upper end needs to be close to or even inserted into the cabinet 1, resulting in that the tray sleeve 4.1 needs to be relatively long, and further making the tray sleeve 4.1 have a larger volume requirement.

[0051] In this application, by connecting the fixed sleeve 6 to the connecting part 5.1 of the main beam support 5 located below the machine housing 1, and by fitting the material tray sleeve 4.1 around 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 machine housing 1. The upper end of the material tray sleeve 4.1 only needs to extend to the location of the connecting part 5.1 located below the machine housing 1. That is, the volume requirement of the material tray sleeve 4.1 can be reduced (that is, while enabling the presser foot sleeve 3.1 and the material tray sleeve 4.1 to be driven separately, the material tray sleeve 4.1 can be made smaller), making the material tray sleeve 4.1 easier to drive, reducing the rotational inertia of the material tray sleeve 4.1 during high-speed operation, and improving the rotation control accuracy; thus, when using this disc embroidery head device for embroidery, the material tray frame and the thread installed on the material tray frame can rotate with higher precision according to the rotation requirements, so as to form a higher quality embroidery.

[0052] The fixing sleeve 6 can be movably connected to the connecting part 5.1, and the fixing sleeve 6 can rotate around the pressure foot sleeve 3.1.

[0053] Alternatively, the retaining sleeve 6 is fixedly connected to the connecting part 5.1. For example, the retaining sleeve 6 may be detachably fixed to the connecting part 5.1 by means of a screw or similar structure, or the retaining sleeve 6 may be non-detachably fixed to the connecting part 5.1 by means of welding or similar methods.

[0054] When the fixed sleeve 6 is movably connected to the connecting part 5.1, although the above-mentioned movement requirements can be met, the fixed sleeve 6 cannot prevent rotational interference between the presser foot sleeve 3.1 and the material tray sleeve 4.1, which can easily cause rotational interference between the presser foot sleeve 3.1 and the material tray sleeve 4.1, leading to embroidery deviation. Therefore, in this embodiment, it is preferable to fix the fixed sleeve 6 to the connecting part 5.1 to better avoid interference between the presser foot sleeve 3.1 and the material tray sleeve 4.1.

[0055] Specifically, the fixing sleeve 6 is fixedly connected to the connecting part 5.1:

[0056] For example, as a connection method, as shown in the appendix Figure 2 and attached Figure 3 As shown, the connecting part 5.1 has a portion that extends to the needle bar 2, and this portion is provided with an insertion hole 5.11 for vertical insertion of the needle bar 2, allowing the needle bar 2 to move up and down. A fixing sleeve 6 is fitted over the presser foot sleeve 3.1, and at least one end of the fixing sleeve 6 is inserted into the insertion hole 5.11, so that the fixing sleeve 6 is fixedly connected to the connecting part 5.1. Alternatively, a connecting member such as a screw can be additionally provided to fix the fixing sleeve 6 to the connecting part 5.1.

[0057] As attached Figure 3As shown in the figure, in this embodiment, the fixed sleeve 6 preferably has a portion that extends downward through the connecting portion 5.1, and the material tray sleeve 4.1 is rotatably fitted around the outer periphery of this fixed sleeve 6, so as to further reduce the volume requirement of the material tray sleeve 4.1.

[0058] Alternatively, as another connection method, the connecting part 5.1 may not have an insertion hole 5.11 while avoiding the needle bar 2, the presser foot sleeve 3.1 and the tray sleeve 4.1; in this case, the fixing sleeve 6 is not fitted into the connecting part 5.1, but the flange structure on the outer periphery of the fixing sleeve 6 is fixed to the connecting part 5.1 of the main beam bracket 5 by, for example, screws.

[0059] Furthermore, in the above scheme, the inner circumference of the fixing sleeve 6 and the outer circumference of the pressure foot sleeve 3.1 can be spaced apart; or, the inner circumference of the fixing sleeve 6 and the outer circumference of the pressure foot sleeve 3.1 can be in contact, that is, viewed from above, the inner circumference of the fixing sleeve 6 and the outer circumference of the pressure foot sleeve 3.1 are in close contact. In this way, the fixing sleeve 6 can position the longer pressure foot sleeve 3.1, improving the overall installation accuracy and the stability of the movement of the pressure foot sleeve 3.1. In this case, the fixing sleeve 6 is preferably a bushing structure with good wear resistance.

[0060] Similarly, in order to improve rotational stability, the inner circumference of the material tray sleeve 4.1 can also make contact with the outer circumference of the fixed sleeve 6.

[0061] Furthermore, to further improve the installation and movement stability of the pressure foot sleeve 3.1, as shown in the attached... Figure 3 As shown, a positioning sleeve 1.1 connected to the housing 1 can also be fitted around the outer periphery of the high-pressure foot sleeve 3.1. The inner periphery of the positioning sleeve 1.1 contacts and engages with the outer periphery of the pressure foot sleeve 3.1 to further improve the positioning effect of the pressure foot sleeve 3.1 and improve the stability of the installation and movement of the pressure foot sleeve 3.1.

[0062] Based on the above solution, for the presser foot rotation drive mechanism:

[0063] As attached Figure 4 As shown, the presser foot rotation drive 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 component 3.6.

[0064] The presser foot rotary motor 3.3 is a rotary motor connected to the main beam 10 of the embroidery machine or the machine housing 1 (generally connected to the machine housing 1) and used to provide rotational power. It has a presser foot rotary motor drive shaft for outputting rotational power, and a first drive wheel 3.4 is fixedly sleeved on the outer periphery of the presser foot rotary motor drive shaft. A first driven wheel 3.5 is sleeved on the outer periphery of the presser foot sleeve 3.1. The first driven wheel 3.5 is connected to the presser foot sleeve 3.1 (e.g., a key connection below), and the first transmission member 3.6 is a transmission belt, transmission chain, transmission gear, or corresponding transmission structure that drives the first drive wheel 3.4 and the first driven wheel 3.5. So that when it is necessary to drive the presser foot sleeve 3.1 to drive the presser foot mounting part 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 drives the first drive wheel 3.4 to rotate, and then drives the first driven wheel 3.5 to rotate through the first transmission member 3.6, thereby driving the presser foot sleeve 3.1 to rotate.

[0065] Depending on the length of the presser foot rotary motor drive shaft, one or more bearing structures that support the presser foot rotary motor drive shaft can be connected to the housing 1.

[0066] In order for the presser foot sleeve 3.1 to rotate stably, the presser foot sleeve 3.1 needs to be rotatably connected or the first driven wheel 3.5 needs to be rotatably connected. However, if the presser foot sleeve 3.1 is rotatably connected to the machine housing 1, when the presser foot rotation drive mechanism rotates, it will generate an unnecessary external force on the presser foot sleeve 3.1, which is likely to pull the presser foot sleeve 3.1 off-center, thus hindering the embroidery action.

[0067] Based on this, in this embodiment, it is preferable to rotatably connect the first driven wheel 3.5 to ensure stable transmission while minimizing the impact on the pressure foot sleeve 3.1.

[0068] As a rotating connection method, the first driven wheel 3.5 can be rotatably connected to the main beam support 5. For example, the first driven wheel 3.5 is placed between the housing 1 and the connection part 5.1 of the main beam support 5, and the lower end of the first driven wheel 3.5 is rotatably connected to the main beam support 5, so that the first driven wheel 3.5 can rotate as described above.

[0069] As another type of rotary connection, the first driven wheel 3.5 is rotatably connected to the housing 1. For example, see attached... Figure 3 As shown, the first driven wheel 3.5 has a portion sleeved on the outer periphery of the positioning sleeve 1.1. This 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 about the needle bar 2 as an axis.

[0070] At this time, the first driven wheel 3.5 can be placed inside the machine housing 1 or outside the machine housing 1 and between the connection part 5.1 of the machine housing 1 and the main beam support 5. However, if the first driven wheel 3.5 is placed between the connection part 5.1 of the machine housing 1 and the main beam support 5, it will force the connection part 5.1, the fixing sleeve 6 and the material tray sleeve 4.1 to move down, occupying too much of the embroidery space below, which may easily cause embroidery interference. Therefore, when the first driven wheel 3.5 is rotatably connected to the machine housing 1, it is preferable to place the first driven wheel 3.5 inside the machine housing 1. This will not only prevent the connection part 5.1, the fixing sleeve 6 and the material tray sleeve 4.1 from moving down, but also protect the driven wheel structure, which is easily affected by dust and other factors that may weaken the smoothness of transmission.

[0071] Furthermore, for the presser foot sleeve 3.1, it is also necessary to adapt to the embroidery action by moving up and down to apply pressure or release pressure to the fabric. Based on the above-mentioned presser foot rotation drive mechanism, in this embodiment, the first driven wheel 3.5 is keyed 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.

[0072] Specifically, either the presser foot sleeve 3.1 or the first 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: while the first driven wheel 3.5 can drive the presser foot sleeve 3.1 to rotate synchronously, the presser foot lifting drive mechanism can also drive the presser foot sleeve 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 sleeve 3.1.

[0073] In this embodiment, the outer surface of the presser foot sleeve 3.1 is provided with a strip groove extending vertically, and the inner surface of the first driven wheel 3.5 has a protrusion and a locking block inserted into the strip groove.

[0074] 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.

[0075] The lifting driving motor 7.1 is a rotating motor connected to the beam 10 or the machine shell 1 (generally connected to the machine shell 1) and used to provide rotating power, has a lifting driving motor driving shaft used to output rotating power, and has a lifting driving motor driving shaft with a lifting driving motor driving shaft fixedly sleeved with a lifting driving motor driving shaft, and one or more lifting driven wheels 7.3 are rotatably connected to the machine shell 1, and the lifting driving motor driving shaft and the one or more lifting driven wheels 7.3 are drivingly connected through the lifting transmission member 7.4. The lifting transmission member 7.4 is a transmission belt or a transmission chain. The lifting transmission member 7.4 has a portion that moves vertically, and the portion is fixedly connected with the driving member 7.5. The driving member 7.5 is driven to move up and down by rotating the lifting driving motor driving shaft through the lifting driving motor 7.1.

[0076] Meanwhile, the presser foot sleeve 3.1 is further provided with: a follow-up connecting portion 3.11 fixedly connected with the presser foot sleeve 3.1 or integrally formed with the presser foot sleeve 3.1, and the follow-up connecting portion 3.11 has a plug-in groove 3.12 arranged around the presser foot sleeve 3.1 and having a notch facing outward. The driving member 7.5 has a driving arm 7.51 adapted to be inserted into the plug-in groove 3.12.

[0077] So that: the presser foot sleeve 3.1 can not only rotate synchronously with the first driven wheel 3.5, but also be driven to move up and down by the driving member 7.5 through the lifting driving motor 7.1, thereby driving the presser foot connected to the bottom of the presser foot sleeve 3.1 to move up and down according to the embroidery action.

[0078] Further, the machine shell 1 can further be provided with a guide rod 7.6 extending vertically, 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.

[0079] Based on the above scheme, for the tray driving mechanism:

[0080] As shown in the accompanying drawings, Figure 4 The tray driving mechanism in the 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.

[0081] The tray driving motor 4.2 is a rotating motor connected to the embroidery machine beam 10 or the machine shell 1 (usually connected to the machine shell 1) and used to provide rotating power, and has a tray driving motor driving shaft for outputting rotating power, and the second driving wheel 4.3 is fixedly sleeved on the outer periphery of the tray driving motor driving shaft. The tray sleeve 4.1 is sleeved with the second driven wheel 4.4 which is fixedly connected to the tray sleeve 4.1 (the fixed connection means that the second driven wheel 4.4 is fixedly connected by screws or other connecting members or is integrally formed with the tray sleeve 4.1), and the second transmission member 4.5 is a transmission belt or a transmission chain or a transmission gear or a corresponding transmission structure for transmission connection between the second driving wheel 4.3 and the second driven wheel 4.4. So that when it is needed to drive the tray sleeve 4.1 to rotate with the tray frame, the tray driving motor 4.2 drives the tray driving motor driving shaft to rotate, which can drive the second driving wheel 4.3 to rotate, and through the second transmission member 4.5, the second driven wheel 4.4 is driven to rotate, thereby driving the tray sleeve 4.1 to rotate.

[0082] According to the length of the tray driving motor driving shaft, one or more bearing structures for supporting the tray driving motor driving shaft can be connected on the machine shell 1.

[0083] Embodiment two:

[0084] The embroidery machine comprises the tray belt embroidery machine head device in any of the schemes in embodiment one and an embroidery machine beam 10, and the machine shell 1 and the beam support 5 of the tray belt embroidery machine head device are connected to the embroidery machine beam 10.
