Description

Technical Field

[0001] The utility model relates to the technical field of embroidery machines, in particular to a presser foot driving mechanism for disk tape embroidery. Background Art

[0002] The disk tape embroidery in a computer embroidery machine is an embroidery process that combines rope embroidery and tape embroidery. In existing disk tape embroidery devices, the design of the thread wheel frame and the presser foot is to achieve synchronous lifting and rotation movements to ensure stability and accuracy during the embroidery process. This design not only improves the embroidery efficiency but also optimizes the embroidery quality. Specifically, the structure of the disk tape embroidery device includes components such as a machine shell, a needle bar part, a presser foot part, and a feeding part. In existing disk tape embroidery devices, the thread wheel frame of the feeding part and the presser foot mounting part of the presser foot part are both driven by the same driving mechanism for lifting and rotation, so that the presser foot part can lift and rotate synchronously with the thread wheel frame, thereby completing complex disk tape embroidery work.

[0003] However, with the continuous enrichment of embroidery products of embroidery machines, consumers' requirements for the types of embroidery products are getting higher and higher. Therefore, the functions of disk tape embroidery devices are becoming more and more complex. The way that the thread wheel frame of the feeding part and the presser foot mounting part of the presser foot part are both driven by the same driving mechanism for lifting and rotation, on the one hand, the presser foot can only rotate synchronously with the thread wheel frame, resulting in poor flexibility of the presser foot and being unable to adapt to multi-functional embroidery processes; on the other hand, in order to increase the continuous working time of disk tape embroidery, the existing feeding part usually uses a large-sized thread wheel frame to carry a large amount of tape material. As the size of the thread wheel frame increases, the load also increases. During the high-speed operation of the disk tape embroidery device, the generated vibration is also greater. Therefore, when the thread wheel frame rotates synchronously with the thread wheel frame, the vibration generated by the thread wheel frame will affect the work of the presser foot, thereby affecting the quality of the embroidery product.

[0015] The presser foot drive mechanism of the disk and tape embroidery machine proposed by the utility model has the following beneficial effects:

[0016] (1) The presser foot drive mechanism includes a presser foot assembly, a lifting assembly and a rotary assembly. The presser foot assembly passes through the machine housing of the disk and tape embroidery machine in the vertical direction. The lifting assembly and the rotary assembly are both arranged on the machine housing of the disk and tape embroidery machine. By providing independent lifting and rotary assemblies in the disk and tape embroidery machine to drive the presser foot to lift and rotate separately, the applicable range of the disk and tape embroidery machine can be wider and more practical, and the quality of the embroidery can be guaranteed.

[0017] (2) The lifting assembly of the presser foot drive mechanism includes a presser foot connecting piece and a lifting drive piece. The presser foot connecting piece is connected to the presser foot sleeve, and the lifting drive piece is connected to the presser foot connecting piece. Thus, when the lifting drive piece operates, the presser foot sleeve is driven by the presser foot connecting piece to lift and lower in the machine housing in the vertical direction.

[0018] (3) The first driving wheel and the first tensioning wheel of the presser foot drive mechanism are arranged horizontally on the motor mounting plate. Therefore, when the first transmission belt is sleeved on the first tensioning wheel, the first tensioning wheel can ensure the tension of the first transmission belt, thereby ensuring the stability of the first transmission belt driving the presser foot connecting piece to lift and lower in the vertical direction, and further ensuring the stability of the presser foot sleeve lifting and lowering in the vertical direction.

[0019] (4) The presser foot drive mechanism connects the presser foot drive fork and the first transmission belt through the presser foot drive seat, which can increase the effective connection area with the first transmission belt, thereby enhancing the structural strength of the connection between the presser foot drive fork and the first transmission belt, and further ensuring the stability of the presser foot sleeve lifting and lowering in the vertical direction.

[0020] (5) The lifting assembly of the presser foot drive mechanism further includes a guide post. The guide post is arranged in the machine housing in the vertical direction and penetrates through the presser foot drive seat. The guide post guides the lifting of the presser foot drive seat in the vertical direction, thereby enhancing the stability of the presser foot drive seat lifting and lowering in the vertical direction, and further ensuring the stability of the presser foot sleeve lifting and lowering in the vertical direction.

[0021] (6) The second driven wheel, the second tensioning wheel and the second transmission belt of this presser foot driving mechanism are arranged on the same horizontal plane. The second driving wheel is connected to the rotating shaft of the second driving motor. The second transmission belt is sleeved on the second driving wheel, the second driven wheel and the second tensioning wheel. Thus, when the second driving motor drives the second driving wheel to rotate, through the engagement of the second transmission belt with the second driving wheel, the second driven wheel and the second tensioning wheel, the second driven wheel, the second tensioning wheel and the second transmission belt are driven to rotate synchronously along the horizontal direction.

[0022] (7) The presser foot transmission member of this presser foot driving mechanism includes a first transmission wheel and a second transmission wheel. The first transmission wheel is connected to the second driven wheel. The second transmission wheel is sleeved on the presser foot sleeve. When the second driven wheel rotates along the horizontal direction, it drives the first transmission wheel to rotate synchronously along the horizontal direction. Thus, through the engagement of the first transmission wheel and the second transmission wheel, the second transmission wheel drives the presser foot sleeve to rotate along the horizontal direction.

[0023] (8) A rotation driving pin is arranged on the second transmission wheel of this presser foot driving mechanism. A strip hole is arranged on the presser foot sleeve along the vertical direction. Through the cooperation of the rotation driving pin and the strip hole, not only can the second transmission wheel drive the presser foot sleeve to rotate synchronously along the horizontal direction, but also the presser foot sleeve can move up and down along the vertical direction on the second transmission wheel. Thus, the lifting assembly can drive the presser foot sleeve to move up and down along the vertical direction. Brief Description of the Drawings

[0030] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0031] A presser foot drive mechanism for a disk embroidery of an embodiment of the present utility model includes a presser foot assembly 1, a lifting assembly 2 connected to the presser foot assembly 1, and a rotating assembly 3 connected to the presser foot assembly 1. The presser foot assembly 1 passes through the machine housing 5 in the vertical direction, and both the lifting assembly 2 and the rotating assembly 3 are provided on the machine housing 5. The lifting assembly 2 is used to drive the presser foot assembly 1 to lift and lower in the vertical direction, and the rotating assembly 3 is used to drive the presser foot assembly 1 to rotate in the horizontal direction.

[0032] In this patent, the presser foot drive mechanism includes a presser foot assembly 1, a lifting assembly 2 and a rotating assembly 3. Among them, the presser foot assembly 1 passes through the machine housing 5 of the disk embroidery device in the vertical direction, and both the lifting assembly 2 and the rotating assembly 3 are provided on the machine housing 5 of the disk embroidery device. It can be foreseen that when the presser foot assembly 1 passes through the machine housing 5 of the disk embroidery device in the vertical direction, it is movably connected to the machine housing 5, so that the presser foot assembly 1 can lift and rotate on the machine housing 5.

[0033] The lifting assembly 2 is connected to the presser foot assembly 1, so that by the operation of the lifting assembly 2, the presser foot assembly 1 can be driven to lift and lower in the vertical direction on the machine housing 5; the rotating assembly 3 is connected to the presser foot assembly 1, so that by the operation of the rotating assembly 3, the presser foot assembly 1 can be driven to rotate in the horizontal direction on the machine housing 5.

[0034] Therefore, in this patent, by providing an independent lifting assembly 2 and a rotating assembly 3 in the disk embroidery device, which are respectively used to drive the presser foot assembly 1 to lift and rotate separately, the applicable range of the disk embroidery device can be made wider and more practical, and the quality of the embroidered product can be guaranteed.

[0035] In this embodiment, the presser foot assembly 1 includes a presser foot sleeve 11 and a presser foot mounting seat 12 for mounting the presser foot sleeve 11 on the machine housing 5. The presser foot mounting seat 12 is movably connected to the presser foot sleeve 11 so that the presser foot sleeve 11 can be lifted and rotated on the machine housing 5. In this patent, the presser foot assembly 1 includes the presser foot sleeve 11 and the presser foot mounting seat 12. The presser foot mounting seat 12 mounts the presser foot sleeve 11 on the machine housing 5, and the presser foot sleeve 11 passes through the machine housing 5 in the vertical direction.

[0036] Since the presser foot mounting seat 12 is movably connected to the presser foot sleeve 11, when the lifting assembly 2 operates, it can drive the presser foot assembly 1 to lift and lower in the vertical direction on the machine housing 5; when the rotating assembly 3 operates, it can drive the presser foot assembly 1 to rotate in the horizontal direction on the machine housing 5.

[0037] Specifically, in actual implementation, the presser foot mounting seat 12 can be a sleeve provided on the machine housing 5. The sleeve is sleeved outside the presser foot sleeve 11, enabling the presser foot sleeve 11 to lift and rotate in the sleeve. When the presser foot sleeve 11 descends to a certain height, the sleeve supports the presser foot sleeve 11, thus preventing the presser foot sleeve 11 from falling off the machine housing 5.

[0038] In this embodiment, the lifting assembly 2 includes a presser foot connecting member connected to the presser foot sleeve 11 and a lifting driving member connected to the presser foot connecting member. The lifting driving member is used to drive the presser foot connecting member to lift and lower in the vertical direction. In this patent, the lifting assembly 2 includes the presser foot connecting member and the lifting driving member. The presser foot connecting member is connected to the presser foot sleeve 11, and the lifting driving member is connected to the presser foot connecting member. Thus, when the lifting driving member operates, it drives the presser foot sleeve 11 to lift and lower in the vertical direction on the machine housing 5 through the presser foot connecting member.

[0039] In this embodiment, the lifting driving member includes a first driving motor 21 mounted on the machine housing 5, a first driving wheel 22 connected to the rotating shaft of the first driving motor 21, a first driven wheel 23 provided on the first driving motor 21, a first tensioning wheel 24 provided on the first driving motor 21, and a first transmission belt 25 sleeved on the first driving wheel 22, the first driven wheel 23, and the first tensioning wheel 24. The first driven wheel 23 and the first tensioning wheel 24 are arranged in the vertical direction, the first driving wheel 22 and the first tensioning wheel 24 are arranged in the horizontal direction, and the presser foot connecting member is connected to the first transmission belt 25.

[0040] In this patent, the lifting driving member includes the first driving motor 21, the first driving wheel 22, the first driven wheel 23, the first tensioning wheel 24, and the first transmission belt 25. A motor mounting plate 211 is provided on the first driving motor 21, and the first driving motor 21 is mounted on the machine housing 5 through the motor mounting plate 211, so that the rotating shaft of the first driving motor 21 is located inside the machine housing 5.

[0041] The first driving wheel 22, the first driven wheel 23 and the first tensioning wheel 24 are arranged inside the motor mounting plate 211. Among them, the first driving wheel 22 is connected to the rotating shaft of the first driving motor 21. The first driven wheel 23 and the first tensioning wheel 24 are arranged vertically on the motor mounting plate 211, and the first driving wheel 22 and the first tensioning wheel 24 are arranged horizontally on the motor mounting plate 211.

[0042] The first transmission belt 25 is sleeved on the first driving wheel 22, the first driven wheel 23 and the first tensioning wheel 24. Since the inner side of the first transmission belt 25 meshes with the first driving wheel 22, the first driven wheel 23 and the first tensioning wheel 24 at the same time, when the rotating shaft of the first driving motor 21 rotates, it drives the first driving wheel 22 to rotate. Through the meshing of the first transmission belt 25 with the first driving wheel 22, the first driven wheel 23 and the first tensioning wheel 24, it drives the first driven wheel 23, the first tensioning wheel 24 and the first transmission belt 25 to rotate synchronously.

[0043] Also, since the first driven wheel 23 and the first tensioning wheel 24 are arranged vertically on the motor mounting plate 211, and the presser foot connecting member is connected to the part of the first transmission belt 25 between the first driven wheel 23 and the first tensioning wheel 24, when the first transmission belt 25 rotates, it can drive the presser foot connecting member to move up and down vertically, thereby driving the presser foot sleeve 11 to move up and down vertically.

[0044] Since the first driving wheel 22 and the first tensioning wheel 24 are arranged horizontally on the motor mounting plate 211, when the first transmission belt 25 is sleeved on the first tensioning wheel 24, the first tensioning wheel 24 can ensure the tension of the first transmission belt 25, thereby ensuring the stability of the first transmission belt 25 driving the presser foot connecting member to move up and down vertically, and further ensuring the stability of the presser foot sleeve 11 moving up and down vertically.

[0045] In this embodiment, a presser foot driving ring 13 is provided at the top of the presser foot sleeve 11. The presser foot connecting member includes a presser foot driving fork 26 clamped with the presser foot driving ring 13, and a presser foot driving seat 27 connecting the presser foot driving fork 26 and the first transmission belt 25. In this patent, the presser foot connecting member includes a presser foot driving fork 26 and a presser foot driving seat 27. A presser foot driving ring 13 is provided at the top of the presser foot sleeve 11, and the presser foot driving fork 26 is clamped with the presser foot driving ring 13.

[0046] One end of the presser foot driving seat 27 is connected to the presser foot driving fork 26, and the other end is connected to the part of the first transmission belt 25 between the first driven wheel 23 and the first tensioning wheel 24. Thus, the presser foot driving fork 26 is connected to the first transmission belt 25 through the presser foot driving seat 27. Further, when the first transmission belt 25 rotates, through the cooperation of the presser foot driving fork 26 and the presser foot driving ring 13, it drives the presser foot sleeve 11 to move up and down vertically.

[0047] The reason for connecting the presser foot driving fork 26 and the first transmission belt 25 through the presser foot driving seat 27 is to increase the effective connection area with the first transmission belt 25, thereby enhancing the structural strength of the connection between the presser foot driving fork 26 and the first transmission belt 25, and further ensuring the stability of the presser foot sleeve 11 during vertical lifting and lowering.

[0048] In this embodiment, the presser foot driving mechanism further includes a guide post 4 vertically arranged in the machine housing 5. The guide post 4 penetrates through the presser foot driving seat 27 and is slidably connected to the presser foot driving seat 27. In this patent, the presser foot driving mechanism further includes a guide post 4, which is vertically arranged in the machine housing 5 and penetrates through the presser foot driving seat 27.

[0049] Since the guide post 4 is slidably connected to the presser foot driving seat 27, when the first transmission belt 25 rotates to drive the presser foot driving seat 27 to lift and lower vertically, the guide post 4 guides the vertical lifting and lowering of the presser foot driving seat 27, thereby enhancing the stability of the presser foot driving seat 27 during vertical lifting and lowering, and further ensuring the stability of the presser foot sleeve 11 during vertical lifting and lowering.

[0050] In this embodiment, the rotation assembly 3 includes a presser foot transmission member connected to the presser foot sleeve 11 and a rotation driving member connected to the presser foot transmission member. The rotation driving member is used to drive the presser foot transmission member to rotate horizontally. In this patent, the rotation assembly 3 includes a presser foot transmission member and a rotation driving member. The presser foot transmission member is connected to the presser foot sleeve 11, and the rotation driving member is connected to the presser foot transmission member, so as to drive the presser foot transmission member to rotate horizontally through the rotation driving member, and further drive the presser foot sleeve 11 to rotate horizontally.

[0051] In this embodiment, the rotation driving member includes a second driving motor 31 mounted on the machine housing 5, a transmission seat 32 connected to the second driving motor 31, a second driving wheel 33 connected to the rotating shaft of the second driving motor 31, a second driven wheel 34 arranged on the transmission seat 32, a second tensioning wheel 35 arranged on the transmission seat 32, and a second transmission belt 36 sleeved on the second driving wheel 33, the second driven wheel 34 and the second tensioning wheel 35. The second driving wheel 33, the second driven wheel 34 and the second tensioning wheel 35 are arranged horizontally.

[0052] In this patent, the rotary driving member includes a second driving motor 31, a transmission seat 32, a second driving wheel 33, a second driven wheel 34, a second tensioning wheel 35, and a second transmission belt 36. Among them, the second driving motor 31 is connected to the transmission seat 32 and fixedly connected to the machine housing 5 through the transmission seat 32, thereby mounting the second driving motor 31 on the machine housing 5. The second driving wheel 33, the second driven wheel 34, the second tensioning wheel 35, and the second transmission belt 36 are all arranged on the transmission seat 32 and are arranged on the same horizontal plane.

[0053] The second transmission belt 36 is sleeved on the second driving wheel 33, the second driven wheel 34, and the second tensioning wheel 35, and the inner side of the second transmission belt 36 is simultaneously engaged with the second driving wheel 33, the second driven wheel 34, and the second tensioning wheel 35. Since the second driving wheel 33 is connected to the rotating shaft of the second driving motor 31, when the second driving motor 31 operates, the rotation of the rotating shaft of the second driving motor 31 can drive the second driving wheel 33 to rotate horizontally. Also, through the engagement of the second transmission belt 36 with the second driving wheel 33, the second driven wheel 34, and the second tensioning wheel 35, the second transmission belt 36, the second driven wheel 34, and the second tensioning wheel 35 are driven to rotate synchronously horizontally.

[0054] In this embodiment, the presser foot transmission member includes a first transmission wheel 37 connected to the second driven wheel 34, and a second transmission wheel 38 sleeved on the presser foot sleeve 11. The first transmission wheel 37 is engaged with the second transmission wheel 38, and the second transmission wheel 38 is slidably connected to the presser foot sleeve 11. In this patent, the presser foot transmission member includes a first transmission wheel 37 and a second transmission wheel 38. The first transmission wheel 37 is connected to the second driven wheel 34, and the second transmission wheel 38 is sleeved on the presser foot sleeve 11.

[0055] Since the first transmission wheel 37 is engaged with the second transmission wheel 38, when the second driven wheel 34 rotates horizontally, it drives the first transmission wheel 37 to rotate synchronously horizontally. Thus, through the engagement of the first transmission wheel 37 with the second transmission wheel 38, the second transmission wheel 38 drives the presser foot sleeve 11 to rotate horizontally.

[0056] Since in this patent, when the second driving motor 31 is mounted on the machine housing 5, the position of the first transmission wheel 37 is fixed. Therefore, in order to ensure the meshing state between the second transmission wheel 38 and the first transmission wheel 37, the position of the second transmission wheel 38 is also fixed. And the presser foot sleeve 11 also needs to be able to move up and down vertically. Therefore, when the second transmission wheel 38 is sleeved on the presser foot sleeve 11, it is slidably connected to the presser foot sleeve 11, so that the presser foot sleeve 11 can move up and down vertically on the second transmission wheel 38.

[0057] In the previous embodiments, it was mentioned that the presser foot sleeve 11 is mounted on the machine housing 5 through the presser foot mounting seat 12. Therefore, in specific implementation, the second transmission wheel 38 can be rotatably connected to the presser foot mounting seat 12, and the presser foot mounting seat 12 supports the second transmission wheel 38, so that the position of the second transmission wheel 38 in the machine housing 5 is fixed and does not affect the rotation of the second transmission wheel 38.

[0058] Specifically, in this embodiment, a rotary drive pin 381 is provided on the second transmission wheel 38, and a strip-shaped hole 111 is provided on the presser foot sleeve 11 in the vertical direction. When the second transmission wheel 38 is sleeved on the presser foot sleeve 11, the rotary drive pin 381 is inserted into the strip-shaped hole 111. Therefore, when the second transmission wheel 38 rotates horizontally, the rotary drive pin 381 acts on the side wall of the strip-shaped hole 111, thereby driving the presser foot sleeve 11 to rotate horizontally synchronously.

[0059] Since the strip-shaped hole 111 is provided on the presser foot sleeve 11 in the vertical direction, the presser foot sleeve 11 can be lifted and lowered in the vertical direction on the second transmission wheel 38 by the rotary drive pin 381 moving in the vertical direction in the strip-shaped hole 111, so that the lifting assembly 2 can drive the presser foot sleeve 11 to lift and lower in the vertical direction.

[0060] In the previous embodiments, it was mentioned that the lowest position of the downward movement of the presser foot sleeve 11 can be limited by the presser foot mounting seat 12, so as to prevent the presser foot sleeve 11 from being pulled out from below the machine housing 5. When the second transmission wheel 38 is installed in the machine housing 5, the presser foot mounting seat 12 supports the second transmission wheel 38 and no longer supports the presser foot sleeve 11. Therefore, it is necessary to limit the lifting height of the presser foot sleeve 11 by the second transmission wheel 38.

[0061] It can be foreseen that: through the cooperation of the rotary drive pin 381 and the strip-shaped hole 111, the lowest position of the downward movement and the highest position of the upward movement of the presser foot mounting seat 12 can be limited, so as to prevent the presser foot sleeve 11 from being pulled out from below or above the machine housing 5, thereby making the practicability of this presser foot driving mechanism stronger.

[0062] The content described above can be implemented alone or in various combinations, and these variant ways are all within the protection scope of the present utility model.

[0063] It should be noted that in this text, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.
