[0018] The embroidery machine disc embroidery device proposed in this invention has the following beneficial effects:

[0019] (1) In this device, the lifting and lowering movement of the needle bar, the lifting and lowering movement of the presser foot assembly, the rotation movement of the presser foot assembly, and the rotation movement of the thread wheel assembly are all driven by independent drive mechanisms. Thus, according to the needs of different embroidery processes, the lifting and lowering movement of the needle bar, the lifting and lowering movement of the presser foot assembly, the rotation movement of the presser foot assembly, and the rotation movement of the thread wheel assembly can be controlled separately, thereby realizing various embroidery processes such as flat embroidery, ribbon embroidery, and rope embroidery, meeting the different embroidery needs of users, and is highly practical.

[0020] (2) The thread clamp, needle bar, thread wheel assembly, presser foot assembly, needle bar drive assembly, thread wheel drive assembly, presser foot lifting assembly and presser foot rotating assembly of this device are all integrated on the same embroidery machine head, so that the structure of this tape embroidery device is compact, which saves space, reduces production costs, and makes this tape embroidery device suitable for small-head-distance embroidery, thus improving the applicability of the embroidery machine.

[0021] (3) Each end of the thread wheel frame of this device is equipped with a winding rod, and each end of the winding rod is equipped with a limit plate, so that a roll of material can be installed on each of the two winding rods. When performing ribbon embroidery or rope embroidery, the material of one roll of material is transported to the embroidery area for embroidery, and the other roll of material is kept as a spare. After the material of the first roll of material is used up, the material of the spare roll of material is transported to the embroidery area for embroidery, thereby reducing the downtime for loading during embroidery operations and thus improving production efficiency;

[0022] (4) This device also includes a skipping needle assembly and a needle bar return assembly. When the embroidery work of an embroidery point is completed and the embroidery point needs to be transferred, the skipping needle assembly is activated, and the drive driver is disengaged from the needle bar, so that the needle bar no longer follows the drive driver to perform high-speed reciprocating up and down motion. The needle bar return assembly drives the needle bar to the upper needle position, so that the embroidery needle on the needle bar is accurately suspended above the fabric, so that the embroidery frame can move the fabric to the next embroidery point and perform the embroidery of the next embroidery point.

[0023] (5) The swing arm of this device is equipped with rollers. When the shaft of the second drive motor rotates and drives the swing arm to swing, the rollers roll into contact with the push rod, pushing the transmission seat to rotate on the first guide rod, thereby disengaging the limiting groove from the limiting block. This makes it easier to achieve the operation of the swing arm pushing the transmission seat to rotate; on the other hand, it protects the swing arm and the transmission seat, thereby enhancing the practicality of this disc embroidery device.

[0024] (6) This device locks the transmission rod and the shaft of the second drive motor by rotating the locking rod on the second drive motor, so that the locking groove on the locking rod cooperates with the locking pin on the transmission rod, thereby locking the swing arm and the driver, so as to facilitate the needle bar return assembly to drive the needle bar to the upper needle position.

Detailed Implementation

[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Please see Figures 1 to 11 An embroidery machine disc embroidery device according to an embodiment of the present invention includes an embroidery machine head 1, a thread clamp 2 disposed on the top of the embroidery machine head 1, a needle bar 3 passing through the embroidery machine head 1 in a vertical direction, a thread wheel assembly 4 disposed at the bottom of the needle bar 3, a presser foot assembly 5 sleeved on the outside of the needle bar 3, a needle bar drive assembly 6 connected to the needle bar 3, a thread wheel drive assembly 7 connected to the thread wheel assembly 4, a presser foot lifting assembly 8 connected to the presser foot assembly 5, and a presser foot rotating assembly 9 connected to the presser foot assembly 5.

[0040] In this patent, the ribbon embroidery device includes an embroidery head 1, a thread clamp 2, a needle bar 3, a thread wheel assembly 4, a presser foot assembly 5, a needle bar drive assembly 6, a thread wheel drive assembly 7, a presser foot lifting assembly 8, and a presser foot rotating assembly 9. The thread clamp 2 is located on the top of the embroidery head 1 and is used for threading the surface thread. It controls the tension of the surface thread during threading, thereby ensuring that the surface thread forms a stitch smoothly under a certain tension.

[0041] The needle bar 3 passes vertically through the embroidery machine head 1, and the top thread, after being guided by the thread clamp 2, passes through the needle bar 3. The needle bar drive assembly 6 is connected to the needle bar 3, thereby driving the needle bar 3 to move up and down vertically, so that the embroidery needle set on the needle bar 3 passes the top thread through the fabric below the embroidery machine head 1.

[0042] The presser foot assembly 5 is sleeved on the outside of the needle bar 3. The presser foot lifting assembly 8 is connected to the presser foot assembly 5 and is used to drive the presser foot assembly 5 to move up and down in the vertical direction. The presser foot rotating assembly 9 is connected to the presser foot assembly 5 and is used to drive the presser foot assembly 5 to rotate in the horizontal direction, so that when the embroidery needle on the needle bar 3 passes the thread through the fabric below the embroidery machine head 1, the presser foot assembly 5 fixes the fabric.

[0043] The thread pulley assembly 4 is located at the bottom of the needle bar 3 and is used to carry the material, which includes a strip or rope. The thread pulley drive assembly 7 is connected to the thread pulley assembly 4 and is used to drive the thread pulley assembly 4 to rotate in the horizontal direction, so that the thread pulley assembly 4 rotates with the needle bar to transport the material.

[0044] In this patent, the lifting and lowering motion of the needle bar 3, the lifting and lowering motion of the presser foot assembly 5, the rotational motion of the presser foot assembly 5, and the rotational motion of the thread wheel assembly 4 are all driven by independent drive mechanisms. Therefore, when performing flat embroidery using this disc embroidery device, the presser foot lifting assembly 8 drives the presser foot assembly 5 to repeatedly lift and lower with the needle, and the needle bar driving assembly 6 drives the needle bar 3 to repeatedly lift and lower with the needle, so that the presser foot assembly 5 fixes the fabric in the embroidery area. The embroidery needle on the needle bar 3 embroiders the surface thread onto the fabric in the embroidery area, thereby forming the corresponding pattern on the fabric and completing the embroidery work.

[0045] When performing ribbon embroidery or rope embroidery using this ribbon embroidery device, the ribbon material carried on the thread wheel assembly 4 passes through the presser foot at the bottom of the presser foot assembly 5. The thread wheel drive assembly 7 drives the thread wheel assembly 4 to rotate with the needle, and in conjunction with the presser foot rotation assembly 9, drives the presser foot assembly 5 to rotate with the needle, thereby conveying the ribbon material to the embroidery area and realizing the conveying of the ribbon material.

[0046] The presser foot lifting assembly 8 drives the presser foot assembly 5 to repeatedly rise and fall with the needle, which in turn drives the needle bar drive assembly 6 to repeatedly rise and fall with the needle. This allows the presser foot assembly 5 to fix the tape and fabric in the embroidery area. The embroidery needle on the needle bar 3 passes the top thread through the tape and fabric in sequence, thus fixing the tape to the fabric and completing the embroidery. Therefore, this tape embroidery device can realize various embroidery techniques such as flat embroidery, tape embroidery, and rope embroidery, thereby meeting different embroidery needs of users and making it highly practical.

[0047] Furthermore, since the thread clamp 2, needle bar 3, thread wheel assembly 4, presser foot assembly 5, needle bar drive assembly 6, thread wheel drive assembly 7, presser foot lifting assembly 8, and presser foot rotating assembly 9 of this tape embroidery device are all integrated on the same embroidery head 1, the tape embroidery device has a compact structure, which saves space, reduces production costs, and makes it suitable for small-head-distance embroidery, thus expanding the applicability of the embroidery machine.

[0048] In this embodiment, the thread drive assembly 7 includes a first drive motor 71, a transmission shaft 72, and a gear set. The first drive motor 71 is disposed on the top of the embroidery head 1, and the transmission shaft 72 is arranged vertically in the embroidery head 1. The rotating shaft of the first drive motor 71 is connected to the transmission shaft 72, so that when the first drive motor 71 is running, it can drive the transmission shaft 72 to rotate in the horizontal direction.

[0049] The gear set connects the drive shaft 72 and the thread wheel assembly 4. When the drive shaft 72 rotates in the horizontal direction, the gear set drives the thread wheel assembly 4 to rotate synchronously in the horizontal direction. As the material on the thread wheel assembly 4 passes through the presser foot at the bottom of the presser foot assembly 5, the material is transported to the embroidery area by the rotation of the thread wheel assembly 4 with the needle and the presser foot assembly 5 with the needle, thus realizing the material transport.

[0050] In this embodiment, the gear set includes a driving gear 73, a driven gear 74, and a gear sleeve 75. The rotating shaft of the first drive motor 71 is fixedly connected to the top of the transmission shaft 72, and the driving gear 73 is disposed at the bottom of the transmission shaft 72. Thus, when the first drive motor 71 drives the transmission shaft 72 to rotate in the horizontal direction, it drives the driving gear 73 to rotate synchronously in the horizontal direction.

[0051] Since the driven gear 74 meshes with the driving gear 73, when the driving gear 73 rotates in the horizontal direction, it drives the driven gear 74 to rotate in the horizontal direction. The gear sleeve 75 is sleeved on the outside of the needle bar 3 and is rotatably connected to the needle bar 3. The thread wheel assembly 4 is fixedly connected to the outer wall of the gear sleeve 75. Since the outer circumference of the gear sleeve 75 has teeth that mesh with the driven gear 74, when the driven gear 74 rotates in the horizontal direction, it drives the gear sleeve 75 to rotate in the horizontal direction, thereby driving the thread wheel assembly 4 to rotate synchronously in the horizontal direction.

[0052] In this patent, the gear sleeve 75 is sleeved on the outside of the needle bar 3. The reason for setting the driven gear 74 between the driving gear 73 and the gear sleeve 75 is to make the transmission shaft 72 and the needle bar 3 a certain distance apart, so as to reserve enough space for the installation of the needle bar drive assembly 6 in the embroidery head 1, thereby preventing the needle bar drive assembly 6 and the thread wheel drive assembly 7 from interfering with each other and ensuring the smooth progress of the embroidery work.

[0053] In this embodiment, the reel assembly 4 includes a reel frame 41, a winding rod 42, and a limiting disc 43. The reel frame 41 is fixedly connected to the outer wall of the gear sleeve 75, so that when the gear sleeve 75 rotates in the horizontal direction, it drives the reel frame 41 to rotate synchronously in the horizontal direction. The winding rod 42 is disposed on the reel frame 41, and a certain length of strip material can be wound on the winding rod 42 to form a strip roll on the winding rod 42, or a strip roll of a certain diameter can be directly installed on the winding rod 42.

[0054] It is foreseeable that the winding rod 42 and the reel frame 41 can be detachably connected, thus facilitating the installation of the material coil on the winding rod 42. Specifically, a plunger or bolt can be inserted through the through hole on the reel frame 41 and connected to the winding rod 42, thereby achieving a detachable connection between the winding rod 42 and the reel frame 41.

[0055] The limiting discs 43 are located at both ends of the winding rod 42. On one hand, they limit the strip roll mounted on the winding rod 42, ensuring it is positioned in the middle of the winding rod 42. On the other hand, they limit the strip roll during its conveying process, preventing lateral deviation. It is foreseeable that when the winding rod 42 is removed from the reel frame 41, the limiting discs 43 can be removed from the end of the winding rod 42, facilitating the installation of the strip roll on the winding rod 42. After the strip roll is installed, the limiting discs 43 are then slipped from the end of the winding rod 42 to the designated position on the winding rod 42 to limit the strip roll on the winding rod 42.

[0056] In practical implementation, a winding rod 42 can be installed at each end of the thread rack 41, and each winding rod 42 has a limit plate 43 at both ends, so that a roll of material can be installed on each of the two winding rods 42. During ribbon embroidery or rope embroidery operations, the material from one roll of material is transported to the embroidery area for embroidery, while the other roll of material is kept as a spare. After the material from the first roll of material is used up, the material from the spare roll of material is transported to the embroidery area for embroidery, thereby reducing downtime for loading during embroidery operations and improving production efficiency.

[0057] In this embodiment, the needle bar drive assembly 6 includes a lifting drive 61, a driver 62, and a first guide rod 63. The lifting drive 61 is disposed in the embroidery head 1 and connected to the driver 62. The first guide rod 63 is vertically disposed in the embroidery head 1 and passes through the driver 62. Therefore, when the lifting drive 61 is running, it can drive the driver 62 to move up and down along the first guide rod 63. The driver 62 cooperates with the needle bar 3, so when the driver 62 moves up and down along the first guide rod 63, it can drive the needle bar 3 to move up and down synchronously in the vertical direction.

[0058] Specifically, in actual implementation, the lifting drive 61 can be composed of a cam mechanism and a linkage mechanism. The cam mechanism is set on the embroidery machine head 1, and the linkage mechanism connects the cam mechanism to the driver 62. Thus, when the cam mechanism is running, the linkage mechanism drives the driver 62 to perform high-speed reciprocating lifting motion along the first guide rod 63. Furthermore, through the cooperation between the driver 62 and the needle bar 3, the needle bar 3 is driven to perform high-speed reciprocating lifting motion in the vertical direction.

[0059] During embroidery work, after the embroidery work at one point is completed, the embroidery needle on the needle bar 3 should be accurately suspended above the fabric so that the embroidery frame can move the fabric to the next embroidery point for embroidery.

[0060] Since the lifting drive 61 drives the needle bar 3 to move up and down at high speed in the vertical direction, it is difficult to ensure that the embroidery needle is accurately suspended above the fabric by controlling the lifting drive 61 to stop running. At this time, when the embroidery frame moves the fabric to the next embroidery point, it may not only cause the embroidery needle to break, but may also cause the embroidery needle to damage the fabric, thus affecting the embroidery work.

[0061] Therefore, in this embodiment, the ribbon embroidery device also includes a skip-needle assembly 10 and a needle bar return assembly 11. The skip-needle assembly 10 is disposed on the embroidery head 1, and the needle bar return assembly 11 is disposed in the embroidery head 1. When the embroidery work of one embroidery point is completed and the embroidery point needs to be transferred, the skip-needle assembly 10 is activated, driving the driver 62 to disengage from the needle bar 3, so that the needle bar 3 no longer follows the driver 62 in high-speed reciprocating lifting and lowering motion.

[0062] After the driver 62 disengages from the needle bar 3, the needle bar return assembly 11 drives the needle bar 3 to the upper needle position, so that the embroidery needle on the needle bar 3 is accurately suspended above the fabric, so that the embroidery frame can move the fabric to the next embroidery point for embroidery.

[0063] Specifically, in this embodiment, the driver 62 includes a transmission frame 621, a transmission seat 622, and a rotary torsion spring 623. The transmission seat 622 is mounted on the transmission frame 621 and rotatably connected to it. A first guide rod 63 passes through the transmission frame 621 and the transmission seat 622. The rotary torsion spring 623 is sleeved on the first guide rod 63, with one end connected to the transmission frame 621 and the other end connected to the transmission seat 622. The transmission frame 621 is connected to the lifting drive component 61, causing the lifting drive component 61 to drive the transmission frame 621, the transmission seat 622, and the rotary torsion spring 623 to move up and down synchronously along the first guide rod 63.

[0064] A limiting block 31 is provided on the needle bar 3, and a limiting groove 6221 is provided on the transmission base 622. During the embroidery process, the limiting block 31 and the limiting groove 6221 are engaged, so that when the transmission base 622 moves up and down along the first guide rod 63, it drives the needle bar 3 to move up and down synchronously in the vertical direction. When the embroidery work of one point is completed and the embroidery point needs to be transferred, the skip needle assembly 10 is activated, driving the transmission base 622 to rotate on the transmission frame 621.

[0065] During the rotation of the transmission base 622, the limiting block 31 disengages from the limiting groove 6221, causing the needle bar 3 to stop following the transmission base 622 in high-speed reciprocating lifting and lowering motion. At this time, the needle bar return assembly 11 drives the needle bar 3 to move to the upper needle position, so that the embroidery needle on the needle bar 3 is accurately suspended above the fabric.

[0066] After the embroidery point transfer is completed, the lifting drive 61 continues to drive the transmission seat 622 to move up and down along the first guide rod 63. At this time, the needle bar 3 is still in the upper needle position. When the transmission seat 622 moves to the same height as the limiting groove 6221 and the limiting block 31, the skip needle assembly 10 no longer acts on the transmission seat 622. At this time, under the elastic force of the rotary torsion spring 623, the transmission seat 622 rotates in the opposite direction until the limiting block 31 and the limiting groove 6221 are engaged. This allows the lifting drive 61 to drive the needle bar 3 to perform high-speed reciprocating up and down movement again to embroider the next embroidery point.

[0067] In this embodiment, the jumper assembly 10 includes a second drive motor 101 and a swing arm 102. The swing arm 102 is connected to the shaft of the second drive motor 101. Therefore, when the shaft of the second drive motor 101 rotates at a certain angle, it can drive the swing arm 102 to swing at a certain angle.

[0068] A push rod 6222 is provided on the transmission base 622, and a roller 1021 is provided on the swing arm 102. When the shaft of the second drive motor 101 rotates, driving the swing arm 102 to swing, the roller 1021 rolls into contact with the push rod 6222, pushing the transmission base 622 to rotate on the first guide rod 63, thereby disengaging the limiting groove 6221 from the limiting block 31.

[0069] In this patent, the reason for using the roller 1021 to roll into contact with the push rod 6222 and drive the transmission seat 622 to rotate on the first guide rod 63 is, on the one hand, to make it easier to achieve the operation of the swing arm 102 driving the transmission seat 622 to rotate; on the other hand, to protect the swing arm 102 and the transmission seat 622, thereby enhancing the practicality of this disc embroidery device.

[0070] In this embodiment, the push rod 6222 extends vertically on the transmission seat 622, while the position of the skipping needle assembly 10 on the embroidery head 1 is fixed. Therefore, after the transfer of the embroidery point is completed, the lifting drive 61 continues to drive the transmission seat 622 to move up and down along the first guide rod 63 until the transmission seat 622 moves to the same height as the limiting groove 6221 and the limiting block 31. At this point, the push rod 6222 disengages from the roller 1021, thereby causing the skipping needle assembly 10 to no longer act on the transmission seat 622.

[0071] Furthermore, in this embodiment, the jumper assembly 10 also includes a reset torsion spring 103 sleeved on the outside of the shaft of the second drive motor 101. One end of the reset torsion spring 103 is fixed to the second drive motor 101, and the other end is fixed to the swing arm 102, for driving the swing arm 102 to reset. In this patent, the swing arm 102 swings in the opposite direction to reset, and there are two driving methods: the first method is to rotate the shaft of the second drive motor 101 in the opposite direction to provide power for the reverse swing of the swing arm 102, thereby resetting the swing arm 102.

[0072] The second method uses the elastic force of the return torsion spring 103 to provide power for the reverse swing of the swing arm 102. Specifically, when the second drive motor 101 starts, the shaft of the second drive motor 101 rotates at a certain angle, causing the swing arm 102 to swing at a certain angle, compressing the return torsion spring 103. When the second drive motor 101 stops, the return torsion spring 103 restores its deformation elastic force, pushing the swing arm 102 and the shaft of the second drive motor 101 to rotate in opposite directions, thus resetting the swing arm 102. In practical implementation, the second driving method is preferred, thereby reducing the need to start the second drive motor 101 and reducing energy consumption.

[0073] In this embodiment, the jumper assembly 10 further includes a first limiting post 104 disposed on the second drive motor 101. The first limiting post 104 is used to limit the swing angle of the swing arm 102 on one side. As mentioned in the previous embodiment, the reverse swing reset of the swing arm 102 is driven by the elastic force of the reset torsion spring 103.

[0074] Therefore, in this patent, the second drive motor 101 is also provided with a first limiting post 104. When the swing arm 102 and the shaft of the return torsion spring 103 are driven to rotate in opposite directions by the elastic force of the return torsion spring 103, the first limiting post 104 limits the swing arm 102 on one side. That is, after the swing arm 102 swings in the opposite direction at a certain angle, it abuts against the first limiting post 104. Thus, the first limiting post 104 limits the stroke of the swing arm 102 in the opposite direction, making the operation of the jumper assembly 10 more stable and efficient.

[0075] In this embodiment, the skip pin assembly 10 further includes a transmission rod 105, a locking pin 1051, and a locking rod 106. The transmission rod 105 is fixedly connected to the rotating shaft of the second drive motor 101, and the locking rod 106 is rotatably connected to the second drive motor 101. The locking pin 1051 is disposed on the transmission rod 105, and the locking rod 106 is provided with a locking groove 1061.

[0076] When the shaft of the second drive motor 101 rotates, it drives the swing arm 102 to swing at a certain angle. The swing arm 102 acts on the transmission seat 622, pushing the transmission seat 622 to rotate at a certain angle on the first guide rod 63. When the limiting groove 6221 on the transmission seat 622 disengages from the limiting block 31 on the needle bar 3, the transmission rod 105 rotates synchronously with the shaft of the second drive motor 101.

[0077] By rotating the locking rod 106 on the second drive motor 101, the locking groove 1061 on the locking rod 106 engages with the locking pin 1051 on the transmission rod 105, thereby locking the transmission rod 105 and the shaft of the second drive motor 101, and further locking the swing arm 102 and the driver 62, keeping the driver 62 in a state of disengagement from the needle bar 3, so that the needle bar return assembly 11 can drive the needle bar 3 to the upper needle position.

[0078] In this embodiment, the jumper assembly 10 further includes two second limiting posts 107 disposed on the second drive motor 101, and a third limiting post 108 disposed on the second drive motor 101. The two second limiting posts 107 are respectively disposed on both sides of the transmission rod 105 to limit the rotation angle of the transmission rod 105 on both sides, and the third limiting post 108 is used to limit the rotation angle of the locking rod 106 on one side.

[0079] In this patent, the jumper assembly 10 also includes two second limiting posts 107, which are respectively disposed on both sides of the transmission rod 105. One of the second limiting posts 107 limits the angle of forward rotation of the transmission rod 105, and the other second limiting post 107 limits the angle of reverse rotation of the transmission rod 105, thereby limiting the angles of forward and reverse rotation of the shaft of the second drive motor 101.

[0080] When the shaft of the second drive motor 101 rotates in the forward direction, it drives the swing arm 102 to rotate in the forward direction, causing the drive driver 62 to disengage from the needle bar 3. Therefore, a second limiting post 107 at one end of the transmission rod 105 limits the angle of forward rotation of the transmission rod 105. Then, the locking groove 1061 on the locking rod 106 engages with the locking post 1051 at the other end of the transmission rod 105 to limit the angle of forward rotation of the transmission rod 105. This makes the locking of the transmission rod 105 more stable, that is, the locking of the swing arm 102 and the drive driver 62 more stable. This keeps the drive driver 62 in a state of disengagement from the needle bar 3, making it easier for the needle bar return assembly 11 to drive the needle bar 3 to the upper needle position.

[0081] As mentioned in the previous embodiments, when the shafts of the drive arm 102 and the second drive motor 101 rotate in opposite directions, a first limiting post 104 at one end of the shaft of the second drive motor 101 limits the movement of the drive arm 102 on one side. Simultaneously, at the other end of the shaft of the second drive motor 101, another second limiting post 107 at one side of the transmission rod 105 limits the movement of the drive rod, thereby making the resetting of the drive arm 102 more stable and efficient.

[0082] In this patent, the skipping needle assembly 10 also includes a third limiting post 108. When the locking rod 106 rotates forward on the second drive motor 101, the locking groove 1061 of the locking rod 106 cooperates with the locking post 1051 on the transmission rod 105 to lock the transmission rod 105. When the locking rod 106 does not lock the transmission rod 105, the third limiting post 108 limits the reverse rotation of the locking rod 106 on one side to prevent the locking rod 106 from rotating freely, thereby making the use of this skipping needle assembly 10 simpler and more efficient.

[0083] In this embodiment, the needle bar return assembly 11 includes a second guide rod 111, a needle bar connector 112, and a return spring 113. The second guide rod 111 is arranged vertically in the embroidery machine head 1. One end of the needle bar connector 112 is fixedly connected to the needle bar 3, and the other end is slidably connected to the second guide rod 111. The return spring 113 is sleeved on the second guide rod 111.

[0084] Since one end of the return spring 113 is fixed and the other end abuts against the needle bar connector 112, the return spring 113 is compressed by the needle bar connector 112 during the process of the needle bar drive assembly 6 driving the needle bar 3 to move downward.

[0085] When the skip stitch assembly 10 is running, during the rotation of the drive driver 62, the drive driver 62 disengages from the needle bar 3 and no longer limits the needle bar 3. At this time, the return spring 113, under the elastic force of restoring its own deformation, pushes the needle bar connector 112 to move vertically on the second guide rod 111, thereby driving the needle bar 3 to move vertically upward synchronously, so that the needle bar 3 automatically runs to the upper needle position, and then the embroidery needle at the bottom of the needle bar 3 is suspended above the fabric.

[0086] Specifically, in actual implementation, the return spring 113 is sleeved on the second guide rod 111. A stop block can be set on the second guide rod 111, with one end of the return spring 113 abutting against the stop block and the other end abutting against the needle bar connector 112. Alternatively, at the fixed connection between the second guide rod 111 and the embroidery head 1, one end of the return spring 113 can be directly abutted against the embroidery head 1 and the other end abutted against the needle bar connector 112.

[0087] In this embodiment, the presser foot assembly 5 includes a presser foot sleeve 51 and a presser foot mounting base 52 that mounts the presser foot sleeve 51 onto the embroidery machine head 1. The presser foot mounting base 52 is movably connected to the presser foot sleeve 51, allowing the presser foot sleeve 51 to be raised, lowered, and rotated on the embroidery machine head 1. In this patent, the presser foot assembly 5 includes a presser foot sleeve 51 and a presser foot mounting base 52. The presser foot mounting base 52 mounts the presser foot sleeve 51 onto the embroidery machine head 1, so that the presser foot sleeve 51 passes through the embroidery machine head 1 in a vertical direction.

[0088] Since the presser foot mounting base 52 is movably connected to the presser foot sleeve 51, when the presser foot lifting assembly 8 is running, it can drive the presser foot assembly 5 to move up and down in the vertical direction on the embroidery machine head 1; when the presser foot rotating assembly 9 is running, it can drive the presser foot assembly 5 to rotate in the horizontal direction on the embroidery machine head 1.

[0089] Specifically, in actual implementation, the presser foot mounting base 52 can be a sleeve set on the embroidery machine head 1. The sleeve is fitted on the outside of the presser foot sleeve 51, so that the presser foot sleeve 51 can be raised, lowered and rotated in the sleeve. When the presser foot sleeve 51 is lowered to a certain height, the sleeve supports the presser foot sleeve 51, thereby preventing the presser foot sleeve 51 from falling off the embroidery machine head 1.

[0090] In this embodiment, a presser foot drive ring 53 is provided on the top of the presser foot sleeve 51. The presser foot lifting assembly 8 includes a first belt drive seat 622, a presser foot connector and a third guide rod 89. The first belt drive assembly is provided on the embroidery machine head 1. The presser foot connector connects the first belt drive assembly to the presser foot drive ring 53. The third guide rod 89 is provided in the vertical direction in the embroidery machine head 1 and passes through the presser foot connector.

[0091] Since the third guide rod 89 is slidably connected to the presser foot connector, when the first belt drive unit is running, it drives the presser foot connector to move back and forth in the vertical direction. The third guide rod 89 guides the movement of the presser foot connector in the vertical direction, thereby driving the presser foot sleeve 51 to rise and fall in the vertical direction through the presser foot connector, thus ensuring the stability of the presser foot sleeve 51 rising and falling in the vertical direction.

[0092] Specifically, in this embodiment, the first belt drive assembly includes a third drive motor 81 mounted on the embroidery machine head 1, a first drive wheel 82 connected to the shaft of the third drive motor 81, a first driven wheel 83 mounted on the third drive motor 81, a first tension wheel 84 mounted on the third drive motor 81, and a first transmission belt 85 sleeved on the first drive wheel 82, the first driven wheel 83, and the first tension wheel 84. The first driven wheel 83 and the first tension wheel 84 are arranged vertically, and the first drive wheel 82 and the first tension wheel 84 are arranged horizontally. The presser foot connector is connected to the first transmission belt 85.

[0093] In this patent, a motor mounting plate 86 is provided on the third drive motor 81, and the third drive motor 81 is mounted on the embroidery head 1 through the motor mounting plate 86, so that the rotating shaft of the third drive motor 81 is located inside the embroidery head 1. The first driving wheel 82, the first driven wheel 83, and the first tension wheel 84 are arranged inside the motor mounting plate 86, wherein the first driving wheel 82 is connected to the rotating shaft of the third drive motor 81, the first driven wheel 83 and the first tension wheel 84 are arranged vertically on the motor mounting plate 86, and the first driving wheel 82 and the first tension wheel 84 are arranged horizontally on the motor mounting plate 86.

[0094] The first transmission belt 85 is sleeved on the first driving pulley 82, the first driven pulley 83, and the first tension pulley 84. Since the inner side of the first transmission belt 85 meshes with the first driving pulley 82, the first driven pulley 83, and the first tension pulley 84 simultaneously, when the shaft of the third drive motor 81 rotates, it drives the first driving pulley 82 to rotate. Through the meshing of the first transmission belt 85 with the first driving pulley 82, the first driven pulley 83, and the first tension pulley 84, the first driven pulley 83, the first tension pulley 84, and the first transmission belt 85 are driven to rotate synchronously.

[0095] Since the first driven wheel 83 and the first tension wheel 84 are arranged vertically on the motor mounting plate 86, and the pressure foot connector is connected to the first transmission belt 85 between the first driven wheel 83 and the first tension wheel 84, when the first transmission belt 85 rotates, it can drive the pressure foot connector to rise and fall vertically, thereby driving the pressure foot sleeve 51 to rise and fall vertically.

[0096] Since the first drive wheel 82 and the first tension wheel 84 are arranged horizontally on the motor mounting plate 86, when the first transmission belt 85 is sleeved on the first tension wheel 84, the first tension wheel 84 can ensure the tension of the first transmission belt 85, thereby ensuring the stability of the first transmission belt 85 driving the presser foot connector to rise and fall in the vertical direction, and thus ensuring the stability of the presser foot sleeve 51 to rise and fall in the vertical direction.

[0097] Specifically, in this patent, the presser foot connector includes a presser foot drive fork 87 that engages with the presser foot drive ring 53, and a presser foot drive seat 88 that connects the presser foot drive fork 87 to the first transmission belt 85. One end of the presser foot drive seat 88 is connected to the presser foot drive fork 87, and the other end is connected to the portion of the first transmission belt 85 located between the first driven pulley 83 and the first tension pulley 84. Thus, the presser foot drive fork 87 is connected to the first transmission belt 85 through the presser foot drive seat 88. When the first transmission belt 85 rotates, the presser foot sleeve 51 is driven to move up and down in the vertical direction through the cooperation between the presser foot drive fork 87 and the presser foot drive ring 53.

[0098] The reason for connecting the presser foot drive fork 87 and the first transmission belt 85 through the presser foot drive seat 88 is to increase the effective connection area with the first transmission belt 85, thereby enhancing the structural strength of the connection between the presser foot drive fork 87 and the first transmission belt 85, and further ensuring the stability of the presser foot sleeve 51 in the vertical direction.

[0099] In this embodiment, the presser foot rotating assembly 9 includes a second belt drive group, a first drive wheel 97 and a second drive wheel 98. The second belt drive group is disposed on the embroidery machine head 1. The first drive wheel 97 is connected to the second belt drive group. The second drive wheel 98 is sleeved on the presser foot tube and meshes with the first drive wheel 97.

[0100] When the second belt drive unit is running, it drives the first drive wheel 97 to rotate in the direction of water, thereby driving the second drive wheel 98 to rotate in the horizontal direction through the meshing of the first drive wheel 97 and the second drive wheel 98, and then driving the pressure foot sleeve 51 to rotate in the direction of water through the second drive wheel 98.

[0101] In this patent, when the second belt drive assembly is installed on the embroidery machine head 1, the position of the first drive wheel 97 is fixed. Therefore, in order to ensure the meshing state of the second drive wheel 98 and the first drive wheel 97, the position of the second drive wheel 98 is also fixed. Since the presser foot sleeve 51 also needs to be able to move up and down in the vertical direction, when the second drive wheel 98 is sleeved on the presser foot sleeve 51, it is slidably connected to the presser foot sleeve 51, so that the presser foot sleeve 51 can move up and down in the vertical direction on the second drive wheel 98.

[0102] As mentioned in the previous embodiments, the presser foot sleeve 51 is mounted on the embroidery machine head 1 via the presser foot mounting base 52. Therefore, in specific implementation, the second drive wheel 98 can be rotatably connected to the presser foot mounting base 52. The presser foot mounting base 52 supports the second drive wheel 98, so that the position of the second drive wheel 98 in the embroidery machine head 1 is fixed and the rotation of the second drive wheel 98 is not affected.

[0103] Specifically, in this patent, the second belt drive assembly includes a fourth drive motor 91, a gear seat 92, a second drive pulley 93, a second driven pulley 94, a second tension pulley 95, and a second transmission belt 96. The fourth drive motor 91 is connected to the gear seat 92 and is fixedly connected to the embroidery machine head 1 via the gear seat 92, thereby mounting the fourth drive motor 91 on the embroidery machine head 1. The second drive pulley 93, the second driven pulley 94, the second tension pulley 95, and the second transmission belt 96 are all disposed on the gear seat 92 and arranged on the same horizontal plane.

[0104] The second transmission belt 96 is sleeved on the second driving pulley 93, the second driven pulley 94, and the second tension pulley 95, and the inner side of the second transmission belt 96 simultaneously meshes with the second driving pulley 93, the second driven pulley 94, and the second tension pulley 95. Since the second driving pulley 93 is connected to the shaft of the fourth drive motor 91, when the fourth drive motor 91 is running, the rotation of the shaft of the fourth drive motor 91 can drive the second driving pulley 93 to rotate in the horizontal direction. Furthermore, through the meshing of the second transmission belt 96 with the second driving pulley 93, the second driven pulley 94, and the second tension pulley 95, the second transmission belt 96, the second driven pulley 94, and the second tension pulley 95 are driven to rotate synchronously in the horizontal direction.

[0105] Specifically, in this embodiment, a rotary drive pin 981 is provided on the second transmission wheel 98, and a strip-shaped hole 511 is provided on the presser foot sleeve 51 along the vertical direction. When the second transmission wheel 98 is sleeved on the presser foot sleeve 51, the rotary drive pin 981 is inserted into the strip-shaped hole 511. Therefore, when the second transmission wheel 98 rotates in the horizontal direction, the rotary drive pin 981 acts on the side wall of the strip-shaped hole 511, thereby driving the presser foot sleeve 51 to rotate synchronously in the horizontal direction.

[0106] Since the strip hole 511 is set vertically on the presser foot sleeve 51, the presser foot sleeve 51 can be raised and lowered vertically on the second transmission wheel 98 by rotating the drive pin 981 in the strip hole 511. This allows the presser foot lifting assembly 8 to drive the presser foot sleeve 51 to rise and fall vertically.

[0107] As mentioned in the previous embodiments, the presser foot mounting base 52 can limit the lowest position of the presser foot sleeve 51 to prevent it from being pulled out from under the embroidery machine head 1. When the second drive wheel 98 is installed inside the embroidery machine head 1, the presser foot mounting base 52 supports the second drive wheel 98 but no longer supports the presser foot sleeve 51. Therefore, it is necessary to limit the lifting height of the presser foot sleeve 51 by the second drive wheel 98.

[0108] It is foreseeable that by cooperating with the rotating drive pin 981 and the strip hole 511, the lowest position of the presser foot mounting base 52 when it descends and the highest position when it rises can be limited, thereby preventing the presser foot sleeve 51 from being pulled out from below or above the embroidery head 1, thus making the practicality of this tape embroidery device stronger.

[0109] The above-described contents can be implemented individually or in various combinations, and these variations are all within the protection scope of this invention.
