Description

Technical Field

[0001] This invention relates to the field of transmission mechanism technology for computerized embroidery machines, and particularly to a ring shuttle transmission mechanism for computerized embroidery machines. Background Technology

[0002] When a computerized embroidery machine is working, the main needle moves back and forth vertically above the embroidery, while the hook moves back and forth horizontally below the embroidery. The two work closely together to pull the embroidery thread. In order to improve the quality of the embroidery, it is necessary to ensure that the movements of the hook and the main needle are highly coordinated.

[0003] In practical use, because the step distance between the main needle and the hook needle is relatively small, when the reversing frequency reaches a certain value, the horizontally moving hook needle is prone to power transmission distortion. The power mechanism struggles to continuously and accurately transmit fine horizontal movements at high speed, causing deviations in the coordination between the hook needle and the main needle during high-speed operation, thus affecting the embroidery quality. Therefore, the upper limit frequency of the smooth reciprocating motion of the hook needle directly determines the working efficiency of the embroidery machine.

[0004] In production, the rotational speed of the gear shaft that drives the hook needle to reciprocate is generally limited to below 1000 rpm; otherwise, the defect rate of the embroidery will increase significantly, which also limits the maximum working efficiency of the embroidery machine and makes it difficult to improve. Summary of the Invention

[0005] To address the problems existing in the prior art, the present invention provides a ring shuttle transmission mechanism for a computerized embroidery machine, which can convert the rotary motion into continuous forward and reverse interval motion of the ring shuttle gear shaft after three transmission reversals, and ensure that the ring shuttle gear shaft maintains stable operation in the higher frequency reversal action, thereby improving the working efficiency of the equipment.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A ring shuttle transmission mechanism for a computerized embroidery machine is disposed between a first shaft and a second shaft. The first shaft extends along the Y direction and is drivenly connected to one or more first motors, and the second shaft extends along the X direction and is drivenly connected to a ring shuttle gear shaft. The ring shuttle transmission mechanism includes:

[0008] The drive module includes a lifting assembly, a shift fork assembly, and a synchronization assembly: the lifting assembly includes an eccentric wheel and a push rod slidably connected thereto; the eccentric wheel is driven by the first shaft and can rotate under its drive to drive the push rod to reciprocate along the Z direction; the shift fork assembly includes a positioning shaft and a connecting rod hinged thereto; one end of the connecting rod is driven by the push rod, and the other end extends to the side of the second shaft; the synchronization assembly includes a synchronization ring synchronously sleeved around the second shaft; one end of the connecting rod is driven by the synchronization ring and can push it to drive the second shaft to reciprocate along the X direction.

[0009] The tracking module includes a tracking motor and a second transmission device connected to it, the second transmission device being connected to the second shaft and capable of driving it to rotate;

[0010] The limiting module includes two limiting members respectively disposed on one X-direction side of the second transmission device. Both limiting members are mounted on the embroidery machine and can limit the X-direction displacement of the second transmission device.

[0011] As a further explanation of the above technical solution:

[0012] In the above technical solution, the eccentric wheel includes a cylindrical first body, one end of which is provided with an eccentric wheel, and the eccentric wheel is connected to the first motor for transmission; the push rod includes a second body, one end of which is provided with a slip ring adapted to the first body, and the other end of which is provided with a third shaft extending along the Y direction.

[0013] In the above technical solution, one end of the eccentric wheel is connected to the first motor for transmission, and the other end is a columnar end, on which the push rod is sleeved; one end of the push rod is a slip ring, and the other end is provided with a third shaft extending along the Y direction.

[0014] In the above technical solution, the connecting rod has a V-shaped structure, including a first arm and a second arm extending to the outside of the positioning shaft. The ends of the first arm and the second arm are both U-shaped ports. The opening of the first arm port extends in the Y direction, and the opening of the second arm port extends in the Z direction. The third shaft is hinged between the two opposite inner walls of the end of the first arm. A dial is hinged to the two opposite inner walls of the end of the second arm. Both ends of each dial extend to the X-direction sides of the U-shaped port.

[0015] In the above technical solution, the outer wall of the synchronization ring is an I-shaped structure, and a groove is provided in the middle of its outer wall, with each dial being disposed in the groove.

[0016] In the above technical solution, the second transmission device includes a drive wheel, a first synchronous belt, a transmission wheel, and a coupling. The drive wheel is driven by the tracking motor. The transmission wheel is driven by the drive wheel through the first synchronous belt. The coupling is sleeved between the transmission wheel and the second shaft. The coupling is driven by the transmission wheel and is detachably fixed to the second shaft.

[0017] In the above technical solution, the coupling is a ring structure, its inner hole is adapted to the second shaft, and its outer wall is uniformly provided with a number of axially extending protrusions along the circumferential direction; the transmission wheel is provided with a number of first sliding grooves that are adapted to the protrusions one by one.

[0018] In the above technical solution, one end of each of the two limiting members is located on the periphery of the coupling, and the other end of each member can be detachably fixed on the embroidery machine.

[0019] In the above technical solution, both the second shaft and the ring shuttle gear shaft are gear shafts, each equipped with a helical gear, and the two helical gears are meshed and connected.

[0020] In the above technical solution, the first motor is an independent motor.

[0021] In the above technical solution, the first motor is an upper spindle motor, which is driven to rotate the upper spindle extending along the X direction. The upper spindle is a gear shaft and is driven to rotate the main needle. A synchronous transmission mechanism is also provided between the upper spindle and the first shaft. The synchronous transmission mechanism includes a fourth gear shaft that is driven to rotate along the X direction and is driven to rotate the upper spindle via a second synchronous belt. The fourth gear shaft is driven to rotate the first shaft via a reversing transmission component.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows: By setting a drive module that is connected to both the first and second shafts, the rotational motion of the first shaft extending in the Y direction can be converted into the axial reciprocating linear motion of the second shaft extending in the X direction after two reversals by the lifting component and the shift fork component and the power transmission by the synchronization component. This enables the second shaft to continuously reciprocate axially under the unidirectional rotation drive of the first shaft. In conjunction with the third reversal transmission of the helical gear on the second shaft and the ring shuttle gear shaft, the ring shuttle gear shaft can be driven to continuously rotate forward and reverse at intervals. By setting a tracking module and a limit module on the second shaft, the second shaft can track the operation of the ring shuttle gear shaft, while enhancing the output torque applied to the second shaft, so as to achieve the purpose of smoothly transmitting the high-frequency forward and reverse rotation of the ring shuttle gear shaft. Furthermore, by further increasing the speed of the first shaft, the forward and reverse rotation frequency of the ring shuttle gear shaft can be increased, thereby improving the working efficiency of the embroidery machine.

[0035] Example 1

[0036] like Figure 1-4 As shown, a ring shuttle transmission mechanism of a computerized embroidery machine is disposed between a first shaft 20 and a second shaft 30. The first shaft 20 extends along the Y direction and is connected to one or more first motors 40 for transmission. The second shaft 30 extends along the X direction and is connected to a ring shuttle gear shaft 50 for transmission. The ring shuttle transmission mechanism includes:

[0037] The drive module 60 includes a lifting assembly 61, a shift fork assembly 62, and a synchronization assembly 63. The lifting assembly 61 includes an eccentric wheel 1 and a push rod 2 slidably connected thereto. The eccentric wheel 1 is driven by the first shaft 20 and can rotate under its drive to drive the push rod 2 to reciprocate along the Z direction. The shift fork assembly 62 includes a positioning shaft 3 and a connecting rod 4 hinged thereto. One end of the connecting rod 4 is driven by the push rod 2, and the other end extends to the side of the second shaft 30. The synchronization assembly 63 includes a synchronization ring 5 synchronously sleeved around the second shaft 30. One end of the connecting rod 4 is driven by the synchronization ring 5 and can push it to drive the second shaft 30 to reciprocate along the X direction.

[0038] The tracking module 70 includes a tracking motor 71 and a second transmission device 72 that is connected to it in a transmission manner. The second transmission device 72 is connected to the second shaft 30 in a transmission manner and can drive it to rotate.

[0039] The limiting module 80 includes two limiting members 10 respectively provided on one side of the second transmission device 72 in the X direction. Both limiting members 10 are installed on the embroidery machine and can limit the X-direction displacement of the second transmission device 72.

[0040] In this embodiment, as Figure 1 As shown, the drive module 60 is installed inside the lower beating ring box 100; the first shaft 20, the second shaft 30 and the positioning shaft 3 are all mounted on the lower beating ring box 100 via bearings.

[0041] Furthermore, such as Figure 5 As shown, one end of the eccentric wheel 1 is connected to the first motor 40 for transmission, and the other end is a columnar end 101, on which a push rod 2 is sleeved; one end of the push rod 2 is a slip ring 202, and the other end is provided with a third shaft 203 extending along the Y direction.

[0042] In this embodiment, a bearing is installed on the columnar end 101, and a slip ring 202 is sleeved on the bearing and can slide on it.

[0043] Furthermore, such as Figure 6 As shown, the connecting rod 4 has a V-shaped structure, including a first arm 401 and a second arm 402 extending to the outside of the positioning shaft 3. The ends of the first arm 401 and the second arm 402 are both U-shaped ports 403. The opening of the port of the first arm 401 extends in the Y direction, and the opening of the port of the second arm 402 extends in the Z direction. A third shaft 203 is hinged between the two opposite inner walls of the end of the first arm 401. A dial 404 is hinged to the two opposite inner walls of the end of the second arm 402. Both ends of each dial 404 extend to the X-direction sides of the U-shaped port 403.

[0044] Furthermore, the outer wall of the synchronization ring 5 has an I-shaped structure, and a groove 501 is provided in the middle of its outer wall, with each dial 404 located in the groove 501.

[0045] Furthermore, the second transmission device 72 includes a drive wheel 6, a first synchronous belt 7, a transmission wheel 8, and a coupling 9. The drive wheel 6 is connected to the tracking motor 71. The transmission wheel 8 is connected to the drive wheel 6 via the first synchronous belt 7. The coupling 9 is sleeved between the transmission wheel 8 and the second shaft 30. The coupling 9 is connected to the transmission wheel 8 and is detachably fixed to the second shaft 30.

[0046] In this embodiment, the drive wheel 6 is mounted on the embroidery machine via bearings (not shown in the accompanying drawings for simplicity).

[0047] Furthermore, such as Figure 7-8 As shown, the coupling 9 has a ring structure, its inner hole is adapted to the second shaft 30, and its outer wall is uniformly provided with a number of axially extending protrusions 901 along the circumferential direction; the transmission wheel 8 is provided with a number of first grooves 801 that are adapted to the protrusions 901 one by one.

[0048] In this embodiment, as Figure 8 As shown, both ends of the driven wheel 8 are provided with coaxial annular protrusions 802, and both ends of each first groove 801 extend to the end faces of the two annular protrusions.

[0049] Furthermore, such as Figure 4 As shown, one end of each of the two limiting members 10 is located on the periphery of the coupling 9, and the other end of each can be detachably fixed on the embroidery machine. Each limiting member 10 is provided with two or more second sliding grooves 1001.

[0050] Understandably, the second slide groove 1001 is designed to facilitate the adjustment of the distance between the limiting member 10 and the transmission wheel 8 and coupling 9, and to facilitate assembly and debugging.

[0051] In this embodiment, as Figure 1-4 As shown, one end of each of the two limiting members 10 is a slip ring, and a bearing is fitted inside each slip ring. Each bearing is fitted on the annular protrusions 802 at both ends of the driven wheel 8, which facilitates the rotation of the driven wheel 8 relative to the limiting member 10, while the limiting member also limits the axial displacement of the driven wheel 8. The axial length of the coupling 9 is equal to or greater than the sum of the axial lengths of the transmission wheel 8 and the two limiting members 10. The axial length of the locking protrusion 901 is greater than the axial length of the first sliding groove 801, so as to ensure that the second shaft 30 always maintains complete contact with the first sliding groove 801 on the transmission wheel 8 during the axial reciprocating movement, thus ensuring the stability of the transmission.

[0052] Furthermore, such as Figure 3 As shown, the second shaft 30 and the ring shuttle gear shaft 50 are both gear shafts, each equipped with a helical gear 11, and the two helical gears 11 are meshed together.

[0053] Furthermore, such as Figure 1As shown, the first motor 40 is an independent motor.

[0054] In application, one or more transmission drive modules 60 can be set at any location on the second shaft 30 to ensure that the entire shuttle transmission mechanism can still maintain efficient and stable transmission when the load is large (synchronously driving a large number of hooks).

[0055] This invention, by setting a drive module 60 connected to both the first shaft 20 and the second shaft 30, can convert the rotational motion of the Y-axis-extending first shaft 20 into the axial reciprocating linear motion of the X-axis-extending second shaft 30 after two reversals via the lifting component 61 and the shift fork component 62 and power transmission via the synchronization component 63. This enables the second shaft 30 to continuously reciprocate axially under the unidirectional rotational drive of the first shaft 20. In conjunction with the third reversal transmission of the helical gear 11 on the second shaft 30 and the ring shuttle gear shaft 50, the ring shuttle gear shaft 50 is driven to continuously rotate forward and reverse at intervals. By setting a tracking module 70 and a limiting module 80 on the second shaft 30, the second shaft 30 can track the operation of the ring shuttle gear shaft 50, while enhancing the output torque applied to the second shaft 30, achieving the purpose of smoothly transmitting the high-frequency forward and reverse rotation of the ring shuttle gear shaft 50. Furthermore, by further increasing the rotational speed of the first shaft 20, the forward and reverse rotation frequency of multiple ring shuttle gear shafts 50 can be increased, thereby improving the working efficiency of the embroidery machine.

[0056] In this embodiment, the first motor 40 and the tracking motor 71 work together to drive the main shaft 20 to a speed of 1500 rpm. Compared with the conventional hook drive mode, the commutation frequency of the ring shuttle gear shaft 50 is higher, which ensures smooth operation while improving the working efficiency of the embroidery machine.

[0057] The working process of this invention is as follows:

[0058] The first motor 40 drives the first shaft 20 to rotate, the first shaft 20 drives the eccentric wheel 1 to rotate, and through the first body 101 drives the third shaft 203 at the end of the push rod 2 to move up and down along the Z direction, pushing the first arm 401 to drive the connecting rod 4 to deflect relative to the positioning shaft 3, thereby driving the dial 404 on the second arm 402 to move back and forth, so as to drive the synchronous ring 5 to drive the second shaft 30 to move back and forth along the X direction; synchronously, the tracking motor 71 drives the second shaft 30 to rotate through the second transmission device 72, so that the second shaft 30 moves back and forth along the X direction while rotating in one direction; synchronously, the second shaft 30 drives the two helical gears 11 to mesh and drive the ring shuttle gear shaft to continuously rotate forward and reverse, so as to drive the hook to move back and forth.

[0059] Example 2

[0060] To further enhance the coordination and consistency of the main stitch and crochet stitch movements, and improve the quality of the embroidery, such as Figure 9As shown, in this embodiment, based on embodiment one, the upper spindle motor 40a, which is connected to the upper spindle 12, is used as the first motor. The upper spindle 12 extends along the X direction and can rotate under the drive of the first motor 40a. The upper spindle 12 is a gear shaft and is connected to the main needle. A synchronous transmission mechanism 90 is also provided between the upper spindle 12 and the first shaft 20. The synchronous transmission mechanism 90 includes a fourth gear shaft 14 that is connected to the upper spindle 12 via a second synchronous belt 13 and extends along the X direction. The fourth gear shaft 14 is connected to the first shaft 20 via a reversing transmission member 15.

[0061] In this embodiment, the reversing transmission component 15 is also a set of meshing helical gears, with the two helical gears synchronously mounted on the fourth gear shaft 14 and the first shaft 20, respectively; the transmission mechanism 90 is surrounded by a sprocket box 110, with the upper main shaft 12 and the fourth gear shaft 14 both mounted on the sprocket box 110 via bearings, the second synchronous belt 13 located inside the box, and the annular transmission component 15 located outside the box.

[0062] In application, depending on the number of embroidery machine heads and the distance between them, the upper main shaft 12 can drive the synchronous transmission mechanism 90 at one or both ends, and then each synchronous transmission mechanism 90 can drive a ring shuttle transmission mechanism to achieve synchronous operation of the upper main shaft 12 and multiple ring shuttle gear shafts 50, further improving the consistency of the main needle and hook needle movement and ensuring the quality of the embroidery.

[0063] The above does not limit the technical scope of the present invention in any way. Any modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention shall still fall within the technical scope of the present invention.
