Description

Technical Field

[0001] This invention relates to the field of embroidery equipment technology, and more specifically to a hybrid embroidery machine. Background Technology

[0002] Embroidery machines, also known as computerized embroidery machines, are the most advanced embroidery machinery of our time. They enable traditional hand embroidery to be completed at high speed and efficiency, and can also achieve the requirements of "multi-layered, multi-functional, uniform, and perfect" results that hand embroidery cannot reach. Traditional embroidery machines are generally equipped with a single type of machine head, such as a flat embroidery head or a ribbon embroidery head, to embroider fabrics, resulting in a relatively limited embroidery method and an inability to adapt to diverse embroidery needs.

[0003] Based on this, hybrid embroidery machines have emerged in the prior art, which are embroidery machines that combine multiple machine head structures. For example, the multi-functional hybrid embroidery machine with publication number CN110565288B is equipped with a worktable, a mounting frame, and at least one flat embroidery machine head and at least one coil embroidery machine head.

[0004] Furthermore, mixed embroidery machines often employ a structure where a single machine head is fitted with a single shuttle box; that is, a shuttle box is installed below the flat embroidery machine head, and another shuttle box is installed below the coil embroidery machine head. This results in a large number of shuttle boxes and a complex overall structure. Moreover, when multiple machine heads of the mixed embroidery machine alternately embroider the fabric, the fabric needs to move from the embroidery area corresponding to the flat embroidery machine head to the embroidery area corresponding to the coil embroidery machine head. This requires a large coverage area for the fabric movement. Since the fabric is fixed on a fabric positioning frame and moved by a positioning frame drive mechanism, this places even greater demands on the movable area of ​​the fabric positioning frame on the positioning frame drive mechanism. This necessitates a longer transmission structure (such as the first transmission belt assembly shown below) to move the fabric positioning frame. However, a longer transmission structure can lead to decreased stability and accuracy, causing the positioning frame drive mechanism to often fail to stably and accurately move the fabric continuously during embroidery, severely impacting the embroidery quality. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a hybrid embroidery machine that reduces the number of shuttle boxes required, simplifies the overall structure, and allows a single shuttle box to accommodate multiple machine heads. Furthermore, it reduces the required fabric movement area, enabling the use of a smaller, more stable positioning frame drive mechanism to drive the fabric for more stable and precise movement, thereby improving the embroidery quality of the fabric.

[0006] The technical solution of the present invention is as follows:

[0007] A hybrid embroidery machine, comprising:

[0008] frame;

[0009] A movable base is slidably connected to the frame. A head assembly and a head drive assembly for driving the head assembly are connected to the movable base. In the slidable direction of the movable base, the head assembly includes: a flat embroidery head and a ribbon embroidery head that are fixed to the movable base at intervals.

[0010] A shuttle box adapted to be disposed below the head assembly;

[0011] After the movable seat slides on the frame, the rotary shuttle box can be positioned opposite the flat embroidery head to form an embroidery mechanism, or the rotary shuttle box can be positioned opposite the ribbon embroidery head to form an embroidery mechanism.

[0012] Furthermore, the shuttle box is connected to a shuttle box drive assembly that drives the shuttle inside the shuttle box to rotate, and the shuttle box drive assembly is set independently of the head drive assembly.

[0013] As a further preferred embodiment, the head drive assembly includes a first drive shaft rotatably connected to the movable seat, and a first rotary motor that provides rotational power to the first drive shaft;

[0014] Furthermore, the first drive shaft has: a portion that is driveably connected to the flat embroidery head so that the rotating first drive shaft can drive the flat embroidery head to operate, and a portion that is driveably connected to the disc embroidery head so that the rotating first drive shaft can drive the disc embroidery head to operate.

[0015] As a further preferred embodiment, the frame has a plurality of slide rails extending in the slidable direction of the movable seat, and the movable seat is slidably connected to the slide rails;

[0016] Furthermore, a lead screw is rotatably connected to the frame, and a third rotary motor that provides rotational force to the lead screw is driven to it.

[0017] The movable seat is provided with a movable mounting part screwed to the lead screw, so that the third rotary motor drives the lead screw to rotate and drive the movable seat to slide.

[0018] As a further preferred option, the hybrid embroidery machine also includes:

[0019] A first displacement sensing component detects when the movable seat slides and the flat embroidery head moves to the embroidery position;

[0020] A second displacement sensing component detects when the movable seat slides and the embroidery head moves to the embroidery position.

[0021] As a further preferred option, the hybrid embroidery machine also includes:

[0022] A third displacement sensing component detects when the moving seat slides and the flat embroidery head moves to the standby position;

[0023] A fourth displacement sensing component detects when the movable seat slides and the embroidery head moves to the standby position.

[0024] As a further preferred option, the hybrid embroidery machine also includes:

[0025] When the first drive shaft in the head drive assembly rotates, a first angle sensing component detects that the first drive shaft has rotated to a set angle.

[0026] As a further preferred option, the hybrid embroidery machine also includes:

[0027] When the first drive shaft in the head drive assembly rotates, a second angle sensing component detects when the first drive shaft rotates to a set angle range.

[0028] As a further preferred option, the hybrid embroidery machine also includes:

[0029] A fabric positioning frame is placed in the middle area between the head assembly and the shuttle box and is used to install and fix the fabric.

[0030] A positioning frame drive mechanism that is connected to the fabric positioning frame and drives the fabric positioning frame to move in accordance with the position of the shuttle box.

[0031] As a further preferred embodiment, the positioning frame drive mechanism includes:

[0032] A horizontal support extending in the left and right direction is provided, and a sliding seat that can slide in the left and right direction is slidably connected to the horizontal support. The sliding seat is fixedly connected to the fabric positioning frame.

[0033] The first transmission mechanism, which is installed on the transverse support, is connected to the sliding seat and drives the sliding seat to slide left and right on the transverse support.

[0034] A longitudinal support extending in the front-to-back direction, wherein the transverse support is slidably connected to the longitudinal support in the front-to-back direction;

[0035] A second transmission mechanism is connected to the transverse support and drives the transverse support to slide back and forth on the longitudinal support.

[0036] As a further preferred embodiment, there are at least two longitudinal supports, and the two longitudinal supports are respectively placed on both sides of the shuttle box, and the transverse support is slidably connected to the two longitudinal supports.

[0037] The main beneficial effects of the above technical solution are as follows:

[0038] By forming a single shuttle box that can accommodate multiple sewing heads, the number of shuttle boxes required can be reduced and the overall structure simplified. It also reduces the required fabric movement area, meaning the fabric only needs to move around a single shuttle box. This allows for the use of a smaller, more stable positioning frame drive mechanism to drive the fabric to move more stably and with higher precision, thereby improving the embroidery quality of the fabric.

[0039] Meanwhile, compared to the transmission connection between the upper shaft driving the machine head and the lower shaft driving the shuttle box in the existing technology, this solution sets the machine head drive component and the shuttle box drive component independently according to the movement requirements of the machine head component. This not only avoids the movement of the machine head component affecting the operation and transmission of the machine head and shuttle box, but also allows for more flexible separate settings of the machine head drive component and the shuttle box drive component, enabling arbitrary and real-time changes in the angle of the shuttle and machine head, which is beneficial for the application of different embroidery threads and embroidery products.

[0040] Further or more detailed beneficial effects will be described in conjunction with specific embodiments in the detailed implementation. Attached Figure Description

Detailed Implementation

[0050] A hybrid embroidery machine has a flat embroidery head and a ribbon embroidery head, which can alternately perform flat embroidery and ribbon embroidery on the fabric. At the same time, the flat embroidery head is often matched with a rotary shuttle box that is positioned opposite to the flat embroidery head to complete the embroidery action together, and the ribbon embroidery head is also often matched with a rotary shuttle box that is positioned opposite to the ribbon embroidery head to complete the embroidery action together.

[0051] Considering the working characteristics of hybrid embroidery machines—that is, the alternating operation of the ribbon embroidery head and the flat embroidery head—some shuttle boxes are always in standby mode. The presence of these shuttle boxes increases the overall cost and structural complexity of the hybrid embroidery machine. Furthermore, when the flat embroidery head and the ribbon embroidery head alternately embroider the fabric, the fabric needs to move from the embroidery area corresponding to the flat embroidery head to the embroidery area corresponding to the ribbon embroidery head. This requires a large coverage area for the fabric movement. Since the fabric is fixed on the fabric positioning frame and moved by the positioning frame drive mechanism, this places greater demands on the movable area of ​​the fabric positioning frame on the positioning frame drive mechanism. This necessitates a longer transmission structure (such as the first transmission belt assembly shown below) to move the fabric positioning frame. However, a longer transmission structure tends to degrade its stability and accuracy, causing the positioning frame drive mechanism to often fail to stably and accurately drive the fabric continuously during embroidery, severely affecting the embroidery quality.

[0052] Based on the above description, to address the problem of how to adapt to the working characteristics of a hybrid embroidery machine to reduce the number of shuttle boxes required to simplify the overall structure while minimizing the coverage area of ​​the fabric movement space during embroidery, and enabling the use of a smaller, more stable positioning frame drive mechanism to drive the fabric for more stable and precise movement, thereby improving the embroidery quality, this invention provides a novel hybrid embroidery machine.

[0053] The present invention will be specifically illustrated below with reference to embodiments:

[0054] Example:

[0055] A hybrid embroidery machine, as shown in the attached image Figure 1 To be continued Figure 7 This includes a frame 1 for forming a support structure, and a movable base 2 slidably connected to the frame 1 at the location where the adapter head is installed. Specifically, see attached... Figure 3 Appendix Figure 4 As shown, two spaced slide rails 101 are arranged laterally on the frame 1. A slider 202 is fixedly connected to each slide rail 101 on the movable seat 2. The slider 202 is slidably connected to the slide rail 101 so that the movable seat 2 can slide laterally left and right on the frame 1.

[0056] The movable seat 2 can be pushed by applying external force to achieve sliding of the movable seat 2 on the frame 1.

[0057] Alternatively, a drive mechanism can be used to drive the movable seat 2 to slide on the frame 1. For example, see attached... Figure 3As shown, a lead screw 102 is rotatably connected to the frame 1. The extension direction of the lead screw 102 is in line with the extension direction of the slide rail 101, which is the sliding direction of the movable seat 2. The lead screw 102 is driven by a third rotary motor 103 that provides rotational force to it. At the same time, the movable seat 2 is provided with a movable mounting part 201 screwed to the lead screw 102. When the third rotary motor 103 drives the lead screw 102 to rotate in the forward or reverse direction, it can drive the movable mounting part 201 to move laterally on the lead screw 102, thereby enabling the movable seat 2 to slide laterally on the frame 1.

[0058] As attached Figure 2 As shown, the movable base 2 is connected to the head assembly 3 and the head drive assembly 4 that drives the head assembly 3 to operate. In the sliding direction of the movable base 2, the head assembly 3 includes: a flat embroidery head 301 and a ribbon embroidery head 302 that are fixed to the movable base 2 at intervals.

[0059] Meanwhile, as attached Figure 2 As shown, a rotary hook box 5 is provided below the head assembly 3. The rotary hook in the rotary hook box 5 can be adapted to the needle in the flat embroidery head 301 to form an embroidery mechanism to perform embroidery on the fabric. The rotary hook in the rotary hook box 5 can also be adapted to the needle in the ribbon embroidery head 302 to form an embroidery mechanism to perform embroidery on the fabric.

[0060] When the movable seat 2 slides on the frame 1, it can move to the position where the rotary shuttle box 5 is opposite to the flat embroidery head 301 to form an embroidery mechanism, or move to the position where the rotary shuttle box 5 is opposite to the tape embroidery head 302 to form an embroidery mechanism.

[0061] The single rotary hook 5 can be adapted to work with either the flat embroidery head 301 or the ribbon embroidery head 302. Furthermore, regardless of whether the sliding seat 2 is used to align the rotary hook 5 with the flat embroidery head 301 or with the ribbon embroidery head 302, the embroidery action remains within a fixed range occupied by the rotary hook 5. Even if the fabric requires alternating between flat and ribbon embroidery, this can be achieved by moving the moving seat 2 to replace the head. The fabric only needs to move within a relatively stable range centered on the rotary hook 5. In this case, a positioning frame drive mechanism 8, configured to match the range of a single rotary hook 5, can be used to drive the fabric to move more stably and with higher precision, as described in detail below.

[0062] The head drive component 4 can exist in various forms.

[0063] In one embodiment, the head drive assembly 4 includes a flat embroidery head drive component that drives the flat embroidery head 301 separately, and a ribbon embroidery head drive component that drives the ribbon embroidery head 302 separately. The flat embroidery head drive component includes a first drive shaft 401 driven to the flat embroidery head 301 and a first rotary motor 402 that provides rotational power to the first drive shaft 401; the ribbon embroidery head drive component includes another first drive shaft 401 driven to the ribbon embroidery head 302 and another first rotary motor 402 that provides rotational power to the first drive shaft 401.

[0064] When the flat embroidery head 301 is aligned with the rotary hook box 5, the drive component of the tape embroidery head controls the tape embroidery head 302 to stop embroidery. When the tape embroidery head 302 is aligned with the rotary hook box 5, the drive component of the flat embroidery head controls the flat embroidery head 301 to stop embroidery.

[0065] In another configuration, the head drive assembly 4 can drive both the flat embroidery head 301 and the ribbon embroidery head 302. See attached diagram for details. Figure 2 As shown, the head drive assembly 4 includes a first drive shaft 401 rotatably connected to the movable base 2, and a first rotary motor 402 that provides rotational power to the first drive shaft 401; and the first drive shaft 401 has: a part that is driveably connected to the flat embroidery head 301 so that the rotating first drive shaft 401 can drive the flat embroidery head 301 to operate, and a part that is driveably connected to the disc embroidery head 302 so that the rotating first drive shaft 401 can drive the disc embroidery head 302 to operate.

[0066] At this time, the flat embroidery head 301 in this embodiment is preferably a flat embroidery head with a clutch drive mechanism, which is configured according to the clutch drive mechanism of an embroidery head and an embroidery head in an embroidery head, as disclosed in CN218291310U. When the first drive shaft 401 rotates, the clutch drive mechanism can control the flat embroidery head 301 to be in the working state of embroidery or the non-working state of standby.

[0067] Meanwhile, the ribbon embroidery head 302 in this embodiment is preferably a ribbon embroidery head with a clutch drive mechanism, which is designed according to the clutch drive mechanism of an embroidery head and the embroidery head in the embroidery head disclosed in CN218291310U. When the first drive shaft 401 rotates, the clutch drive mechanism can control the ribbon embroidery head 302 to be in the working state of embroidery or the non-working state of standby.

[0068] Thus, when one embroidery head, such as the flat embroidery head 301, moves to the embroidery position (i.e., the head is aligned with the shuttle box 5 so that it can embroider the fabric together with the shuttle box 5) and performs embroidery work under the drive of the rotating first drive shaft 401, the other embroidery head, such as the ribbon embroidery head 302, can move to the standby position (i.e., the head is not aligned with the shuttle box 5), and the ribbon embroidery head 302 can be put into a standby non-working state through the clutch drive mechanism. Similarly, when it is necessary to switch embroidery heads, the flat embroidery head 301 can be controlled to be in a standby non-working state, and the ribbon embroidery head 302 can be controlled to be in the embroidery working state.

[0069] Furthermore, the shuttle box 5 is connected to a shuttle box drive assembly 6 that drives the shuttle inside the shuttle box 5 to rotate, and the shuttle box drive assembly 6 is set independently of the head drive assembly 4. This allows for more flexible settings of the head drive assembly 4 and the shuttle box drive assembly 6, enabling arbitrary and real-time changes in the angle between the shuttle and the head, which is beneficial for using different embroidery threads and embroidery products.

[0070] In this embodiment, as shown in the appendix Figure 2 As shown, the shuttle box drive assembly 6 includes: a second drive shaft 601 that is driven by the shuttle box 5, and a second rotary motor 602 that is driven by the second drive shaft 601 and provides power to the second drive shaft 601. At this time, the first drive shaft 401 and the second drive shaft 601 are independently arranged.

[0071] As attached Figure 1 Appendix Figure 7 As shown, the mixed embroidery machine also includes: a fabric positioning frame 7 located in the middle area between the head assembly 3 and the shuttle box 5 for mounting and fixing the fabric, and a positioning frame drive mechanism 8 connected to the fabric positioning frame 7 and driving the fabric positioning frame 7 to move in a position matching the shuttle box 5 (i.e., preferably driving the fabric positioning frame 7 to move mainly around the embroidery area where the shuttle box 5 is located as the center position).

[0072] Among them, as attached Figure 7 As shown, the positioning frame drive mechanism 8 includes components in the left and right directions (i.e., for example, attached). Figure 7 A transverse support 801 is extended in the direction shown in A. The center of the transverse support 801 is preferably aligned with the rotary hook box 5. A sliding seat 802 that can slide in the left and right directions is slidably connected to the transverse support 801. The sliding seat 802 is fixedly connected to the fabric positioning frame 7.

[0073] As attached Figure 7As shown, a first transmission mechanism 803 is installed on the horizontal support 801. The first transmission mechanism 803 is connected to the sliding seat 802 and drives the sliding seat 802 to slide left and right on the horizontal support 801, thereby driving the fabric positioning frame 7 and the fabric fixed on the fabric positioning frame 7 to slide left and right.

[0074] For details, see attached. Figure 7 As shown, the first transmission mechanism 803 in this embodiment includes: a fourth rotary motor 8031 ​​fixed on a transverse support 801, a first transmission wheel 8032 rotatably connected to the transverse support 801, and a first transmission belt assembly 8033 mounted on the transverse support 801. The first transmission belt assembly 8033 includes two transmission wheels spaced apart and rotatably connected to the transverse support 801, and a transmission belt connecting the two transmission wheels. A sliding seat connecting block 8021 is fixedly connected to the transmission belt and is fixedly connected to the sliding seat 802. The fourth rotary motor 8031 ​​is connected to the first transmission wheel 8032 via the transmission belt, and the first transmission wheel 8032 is coaxially rotatably arranged with one of the transmission wheels in the first transmission belt assembly 8033. The outer diameter of the first transmission wheel 8032 is larger than the outer diameter of the transmission wheel in the first transmission belt assembly 8033 and also larger than the outer diameter of the output shaft of the fourth rotary motor 8031.

[0075] The fourth rotary motor 8031 ​​drives the transmission belt in the first transmission belt assembly 8033 to move the sliding seat 802 and the fabric positioning frame 7 left and right.

[0076] As attached Figure 7 As shown, a cross brace 801 is provided below it in the front-to-back direction (e.g., attached). Figure 7 The longitudinal support 804 extends in the direction shown in B) and the transverse support 801 has a transverse support connecting block 8011 at its bottom. The transverse support connecting block 8011 is slidably connected to the longitudinal support 804 so that the transverse support 801 can be slidably connected to the longitudinal support 804 back and forth.

[0077] As attached Figure 7 As shown, a second transmission mechanism 805 is also provided, which is connected to the transverse support 801 and drives the transverse support 801 to slide back and forth on the longitudinal support 804.

[0078] Specifically, the second transmission mechanism 805 includes a fifth rotary motor 8051, a second transmission wheel 8052, a transmission shaft 8053, and a second transmission belt assembly 8054. The fifth rotary motor 8051 is connected via a transmission belt to the second transmission wheel 8052, which is fixedly mounted on the transmission shaft 8053. The second transmission belt assembly 8054 includes two transmission wheels spaced apart and rotatably connected to the longitudinal support 804, and a transmission belt connecting these two transmission wheels. This transmission belt is fixedly connected to the transverse support connecting block 8011, and one of the transmission wheels in the second transmission belt assembly 8054 is fixedly mounted on the transmission shaft 8053.

[0079] When the fifth rotating motor 8051 drives the second transmission wheel 8052 to rotate and drives the transmission shaft 8053 to rotate, the transmission wheel in the second transmission belt assembly 8054 rotates synchronously and drives the transmission belt in the second transmission belt assembly 8054 to move, so as to drive the transverse support 801, the sliding seat 802 and the fabric positioning frame 7 to move back and forth as a whole.

[0080] As attached Figure 7 As shown, there are at least two longitudinal supports 804, and the two longitudinal supports 804 are respectively placed on both sides of the shuttle box 5. The transverse support 801 is slidably connected to the two longitudinal supports 804 to provide better sliding support for the transverse support 801. At this time, a second transmission belt assembly 8054 can be provided on both longitudinal supports 804, and both second transmission belt assemblies 8054 are drivenly connected to a transmission shaft 8053.

[0081] Based on the above, and considering the embroidery malfunction caused by movement deviation during the replacement and movement of the machine head.

[0082] In this embodiment, a first displacement sensing component is provided to detect when the flat embroidery head 301 moves to the embroidery position (the head and the shuttle box 5 are aligned to perform embroidery work) when the movable seat 2 slides, and a second displacement sensing component to detect when the tape embroidery head 302 moves to the embroidery position (the head and the shuttle box 5 are aligned to perform embroidery work) when the movable seat 2 slides.

[0083] When the flat embroidery head 301 is aligned with the rotary hook box 5 by sliding the movable seat 2, the first displacement sensing component detects whether the flat embroidery head 301 has moved to the corresponding position. When the ribbon embroidery head 302 is aligned with the rotary hook box 5 by sliding the movable seat 2, the second displacement sensing component detects whether the ribbon embroidery head 302 has moved to the corresponding position. This improves the accuracy of the head alignment and reduces the possibility of embroidery malfunctions due to head misalignment.

[0084] Alternatively, a third displacement sensing component is provided to detect when the moving seat 2 slides and the flat embroidery head 301 moves to the standby position (i.e., the position of the flat embroidery head 301 when the ribbon embroidery head 302 is aligned with the rotary shuttle box 5), and a fourth displacement sensing component is provided to detect when the moving seat 2 slides and the ribbon embroidery head 302 moves to the standby position (i.e., the position of the ribbon embroidery head 302 when the flat embroidery head 301 is aligned with the rotary shuttle box 5).

[0085] Since the distance between the flat embroidery head 301 and the ribbon embroidery head 302 is fixed, the standby position of the head is set according to the distance between the flat embroidery head 301 and the ribbon embroidery head 302, as well as the alignment position between the head and the rotary hook box 5. Detecting whether the flat embroidery head 301 is in the standby position determines whether the ribbon embroidery head 302 is in the embroidery position; conversely, detecting whether the ribbon embroidery head 302 is in the standby position determines whether the flat embroidery head 301 is in the embroidery position.

[0086] The aforementioned first displacement sensing component, second displacement sensing component, third displacement sensing component, and fourth displacement sensing component can be photoelectric sensors, acoustic sensors, pull rope switches, pressure sensors, etc., used to detect whether an object has moved to a set position.

[0087] In this embodiment, the first displacement sensing component, the second displacement sensing component, the third displacement sensing component, and the fourth displacement sensing component are preferably photoelectric sensors.

[0088] For details, see attached. Figure 5 As shown, each displacement sensing component in this embodiment includes a position sensor a1 disposed on the frame 1. The position sensor a1 includes a position sensor light-emitting end a101 and a position sensor receiving end a102 disposed vertically at intervals. The position sensor light-emitting end a101 emits light, and the position sensor receiving end a102 receives the light, forming a light receiving signal and transmitting it to the controller of the hybrid embroidery machine. Simultaneously, the displacement sensing component also includes a position sensor light-blocking component a2, which is disposed on the machine head where the position to be detected (e.g., attached to the machine head). Figure 5As shown, when the position of the ribbon embroidery machine head 302 needs to be detected, the position sensor light-blocking component a2 is fixedly connected to the ribbon embroidery machine head 302. The position of the position sensor light-blocking component a2 on the machine head is adapted to the spacing between the position sensor light-emitting end a101 and the position sensor receiving end a102. When the machine head slides laterally, the position sensor light-blocking component a2 can be inserted into the gap between the position sensor light-emitting end a101 and the position sensor receiving end a102, thereby blocking the light. The position sensor receiving end a102 generates a signal of not receiving light and transmits it to the controller of the mixed embroidery machine. That is, it is clearly detected that the machine head with the position sensor light-blocking component a2 has moved to a certain set position, and the moving base 2 can be controlled to stop moving. The position sensor a1 and the position sensor light-blocking component a2 are specifically set according to the position of the machine head to be detected and the set detection position.

[0089] The first, second, third, and fourth displacement sensing components are all configured with reference to the aforementioned displacement sensing components. Furthermore, in each displacement sensing component, the position sensor a1 is set at a different position on the frame 1 according to the detection position requirements, and the position sensor light-blocking component a2 is set on the corresponding machine head where position detection is required, according to the detection requirements.

[0090] Furthermore, in the above scheme, the embroidery needle in the flat embroidery head 301 and the embroidery needle in the coil embroidery head 302 can be moved up and down by rotating the first drive shaft 401. Therefore, the position height of the embroidery needle in the head can be detected by controlling the rotation angle of the first drive shaft 401.

[0091] To prevent the embroidery needles in the machine head from being too low during the movement of the movable seat 2, i.e., having a portion placed below the fabric, which could cause severe rubbing against the fabric during the movement of the movable seat 2, this embodiment includes a second angle sensing component that detects when the first drive shaft 401 rotates to a set angle range, so that the embroidery needles in the flat embroidery machine head 301 and the ribbon embroidery machine head 302 are both positioned above the fabric accommodating space. This set angle range is specifically set based on the path of the embroidery needles moving up and down in the machine head driven by the first drive shaft 401, and the distance between the fabric and the machine head, so that when the rotation angle of the first drive shaft 401 is within this set angle range, the embroidery needles in the flat embroidery machine head 301 and the ribbon embroidery machine head 302 are both positioned above the fabric.

[0092] As attached Figure 5 and attached Figure 6As shown, the second angle sensing component in this embodiment includes: a second bushing c2 fixedly sleeved around the outer periphery of the first drive shaft 401, and a second angle sensor c1 adapted to the position of the second bushing c2 and fixedly connected to the movable seat 2. The second angle sensor c1 includes: a second angle sensor light-emitting end c101 for emitting light and a second angle sensor receiving end c102 for receiving the light, which are spaced apart in the extending direction of the first drive shaft 401.

[0093] Meanwhile, a second bushing c2 is provided around its outer periphery with a second bushing light-blocking flange c201 that separates the light-emitting end c101 and the receiving end c102 of the second angle sensor. The light-blocking flange c201 is adapted to the above-mentioned set angle range and is provided with a second clearance notch c202 at intervals between the light-emitting end c101 and the receiving end c102 of the second angle sensor.

[0094] When the machine head needs to be replaced, the second bushing c2 rotates with the first drive shaft 401 to:

[0095] When the second bushing light-blocking flange c201 is placed between the light-emitting end c101 and the receiving end c102 of the second angle sensor, the receiving end c102 of the second angle sensor generates a signal that it has not received light and transmits it to the controller that drives the first drive shaft 401 to rotate. This indicates that the first drive shaft 401 has not rotated to the set angle range and needs to be controlled to rotate the first drive shaft 401 further.

[0096] When the second clearance notch c202 is placed between the light-emitting end c101 and the receiving end c102 of the second angle sensor, the receiving end c102 of the second angle sensor generates a light signal and transmits it to the controller that drives the first drive shaft 401 to rotate. That is, when the first drive shaft 401 rotates to the set angle range, the controller can stop the first drive shaft 401 from rotating and perform the subsequent movement of the moving seat 2 to change the machine head.

[0097] Furthermore, based on the above, when the first drive shaft 401 rotates to a set angle range so that the embroidery needles in the flat embroidery head 301 and the embroidery needles in the ribbon embroidery head 302 are both positioned above the fabric receiving space, and the moving seat 2 is moved to complete the head replacement work, for example, attached... Figure 4 As shown, the ribbon embroidery head 302 moves to a position opposite to the rotary shuttle box 5 to prepare for embroidery, while the flat embroidery head 301 moves to a standby position to prepare for stopping work.

[0098] At this time, the height of the embroidery needle in the tape embroidery head 302 and the embroidery needle in the flat embroidery head 301 may not be at the originally set starting height position of the embroidery needle. Therefore, if the tape embroidery head 302 is driven to work directly with this state as the starting state, it is easy to cause certain disorder in the movement of the embroidery needle, which cannot be perfectly adapted to the embroidery action set by the embroidery machine system. It is easy to cause deviation when cooperating with the rotary hook in the rotary hook box 5 to perform embroidery action.

[0099] Therefore, it is necessary to further detect and control the height movement of the embroidery needle to a set position, that is, to detect and control the first drive shaft 401 to rotate to a set angle. Of course, during embroidery, the starting height of the embroidery needle is above the fabric, so this set angle is within the aforementioned set angle range.

[0100] Specifically, in this embodiment, as shown in the appendix Figure 5 and attached Figure 6 As shown, when the first drive shaft 401 rotates, a first angle sensing component detects when the first drive shaft 401 rotates to a set angle. This set angle is the angle at which the first drive shaft 401 adapts to rotation when the embroidery needle in the machine head is at the initial embroidery height.

[0101] Specifically, the first angle sensing component includes a first bushing b2 fixedly sleeved around the outer periphery of the first drive shaft 401, and a first angle sensor b1 fixedly mounted on the movable seat 2 in accordance with the position of the first bushing b2. The first angle sensor b1 includes a first angle sensor light-emitting end b101 for emitting light and a first angle sensor receiving end b102 for receiving the light, which are spaced apart in the extending direction of the first drive shaft 401.

[0102] Meanwhile, the outer periphery of the first bushing b2 is provided with a first bushing light-blocking flange b201 that separates the light-emitting end b101 and the receiving end b102 of the first angle sensor. The light-blocking flange b201 is adapted to the above-mentioned set angle and is provided with a first clearance notch b202 at intervals between the light-emitting end b101 and the receiving end b102 of the first angle sensor.

[0103] Referring to the principle of the second angle sensing component described above, the first bushing b2 rotates with the first drive shaft 401 to:

[0104] When the first bushing light-blocking flange b201 is placed between the light-emitting end b101 and the receiving end b102 of the first angle sensor, the receiving end b102 of the first angle sensor generates a signal that it has not received light and transmits it to the controller that drives the first drive shaft 401 to rotate. This indicates that the first drive shaft 401 has not rotated to the set angle and needs to be controlled to rotate the first drive shaft 401 further.

[0105] When the first clearance notch b202 is placed between the light-emitting end b101 and the receiving end b102 of the first angle sensor, the receiving end b102 of the first angle sensor generates a light signal and transmits it to the controller that drives the first drive shaft 401 to rotate, thus confirming that the first drive shaft 401 has rotated to the set angle and can perform subsequent embroidery actions.
