[0041] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0042] The disclosure below provides many different embodiments or examples for realizing different structures of the utility model. In order to simplify the disclosure of the utility model, the components and settings of specific examples are described below. Of course, they are merely examples, and the purpose is not to limit the utility model. In addition, the utility model can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the utility model provides various specific examples of processes and materials, but those of ordinary skill in the art can be aware of the applicability of other processes and / or the use of other materials.

[0043] like Figure 1-Figure 10As shown, a thread take-up mechanism according to an embodiment of the first aspect of the utility model comprises: a thread take-up lever 10 , a thread take-up cam 20 , a thread take-up drive assembly 30 and a clutch mechanism 40 .

[0044] The thread take-up driving assembly 30 includes a first thread take-up driving rod 31 , and a power input end 311 of the first thread take-up driving rod 31 is disposed corresponding to the thread take-up cam 20 .

[0045] The thread take-up drive assembly 30 has a working position and a static position. When the thread take-up drive assembly 30 is in the working position, the power input end 311 of the first thread take-up drive rod 31 cooperates with the thread take-up cam 20; when the thread take-up drive assembly 30 is in the static position, the power input end 311 of the first thread take-up drive rod 31 disengages from the thread take-up cam 20.

[0046] The clutch mechanism 40 enables the thread take-up drive assembly 30 to switch between a working position and a rest position.

[0047] It should be noted that in actual applications, the number of machine heads can be multiple. For example, the number of machine heads is 4: the first machine head, the second machine head, the third machine head and the fourth machine head, and the thread take-up cam 20 corresponding to the first machine head, the thread take-up cam 20 corresponding to the second machine head, the thread take-up cam 20 corresponding to the third machine head and the thread take-up cam 20 corresponding to the fourth machine head are all installed on the main shaft.

[0048] The first and third heads are set to work, and the second and fourth heads are set to not work. Then the power input end 311 of the first thread take-up drive rod 31 of the thread take-up drive assembly 30 corresponding to the first head cooperates with the thread take-up cam 20, so that the thread take-up drive assembly 30 corresponding to the first head is in the working position; the power input end 311 of the first thread take-up drive rod 31 of the thread take-up drive assembly 30 corresponding to the third head cooperates with the thread take-up cam 20, so that the thread take-up drive assembly 30 corresponding to the third head is in the working position. At the same time, the power input end 311 of the first thread take-up drive rod 31 of the thread take-up drive assembly 30 corresponding to the second head is disengaged from the thread take-up cam 20, so that the thread take-up drive assembly 30 corresponding to the second head is in a static position; the power input end 311 of the first thread take-up drive rod 31 of the thread take-up drive assembly 30 corresponding to the fourth head is disengaged from the thread take-up cam 20, so that the thread take-up drive assembly 30 corresponding to the fourth head is in a static position.

[0049] In this way, when the computer embroidery machine starts the inter-head embroidery function, the thread take-up rod 10 corresponding to the closed head can stop moving, avoiding meaningless movement of the thread take-up rod 10 corresponding to the closed head and avoiding accidental breakage of the embroidery thread on the thread take-up rod 10 corresponding to the closed head.

[0050] It should be noted that those skilled in the art can select the non-working heads according to actual conditions. For example, the first head and the fourth head can be set to work, and the second head and the third head can be set to not work; the first head can be set, and the second head, the third head, and the fourth head can be set to not work; ..., which are not listed one by one in this embodiment.

[0051] In some embodiments of the present invention, Figure 1-Figure 5 As shown, the thread take-up mechanism further includes a support shaft 80 , and the first thread take-up driving rod 31 is sleeved on the support shaft 80 .

[0052] The clutch mechanism 40 causes the first thread take-up driving rod 31 to reciprocate along the axial direction of the support shaft 80 and the power input end 311 of the first thread take-up driving rod 31 is engaged with or disengaged from the thread take-up cam 20, or,

[0053] The clutch mechanism 40 enables the support shaft 80 to reciprocate along its axial direction and the power input end 311 of the first thread take-up driving lever 31 is engaged with or disengaged from the thread take-up cam 20 .

[0054] It should be noted that, in actual application, the thread take-up drive assembly 30 further includes a second thread take-up drive rod 32, and the second thread take-up drive rod 32 is connected to the first thread take-up drive rod 31. The power output end 321 of the second thread take-up drive rod 32 is arranged corresponding to the thread take-up rod 10.

[0055] When the thread take-up drive assembly 30 is in the working position, the power input end 311 of the first thread take-up drive rod 31 cooperates with the thread take-up cam 20; the power output end 321 of the second thread take-up drive rod 32 cooperates with the thread take-up rod 10; the thread take-up drive assembly 30 is in the static position, the power input end 311 of the first thread take-up drive rod 31 disengages from the thread take-up cam 20; the power output end 321 of the second thread take-up drive rod 32 disengages from the thread take-up rod 10.

[0056] In the first specific embodiment, the first thread take-up driving rod 31 and the second thread take-up driving rod 32 are sleeved on the support shaft 80 , and the first thread take-up driving rod 31 and the second thread take-up driving rod 32 are connected to each other.

[0057] The clutch mechanism 40 enables the first thread take-up driving rod 31 to reciprocate along the axis direction of the support shaft 80, that is, the first thread take-up driving rod 31 and the second thread take-up driving rod 32 to reciprocate along the axis direction of the support shaft 80 together. Figure 6As shown, the first thread take-up drive rod 31 and the second thread take-up drive rod 32 move rightward along the axial direction of the support shaft 80 together, and the power input end 311 of the first thread take-up drive rod 31 is inserted into the cam groove 21 of the thread take-up cam 20, and the power input end 311 of the first thread take-up drive rod 31 can be in rolling contact with the cam groove 21, thereby realizing the cooperation between the power input end 311 of the first thread take-up drive rod 31 and the thread take-up cam 20; at the same time, the power output end 321 of the second thread take-up drive rod 32 is inserted into the groove of the thread take-up rod 10, thereby realizing the cooperation between the power output end 321 of the second thread take-up drive rod 32 and the thread take-up rod 10.

[0058] like Figure 7 As shown, the first thread take-up drive rod 31 and the second thread take-up drive rod 32 move leftward along the axial direction of the support shaft 80 together, and the power input end 311 of the first thread take-up drive rod 31 disengages from the cam groove 21 of the thread take-up cam 20, and there is a gap d between the two, thereby realizing the disengagement of the power input end 311 of the first thread take-up drive rod 31 from the thread take-up cam 20; at the same time, the power output end 321 of the second thread take-up drive rod 32 disengages from the groove of the thread take-up rod 10, thereby realizing the disengagement of the power output end 321 of the second thread take-up drive rod 32 from the thread take-up rod 10.

[0059] In the second specific embodiment, the first thread take-up driving rod 31 and the second thread take-up driving rod 32 are sleeved on the support shaft 80 , and the first thread take-up driving rod 31 and the second thread take-up driving rod 32 are connected to each other.

[0060] The clutch mechanism 40 enables the support shaft 80 to reciprocate along its axial direction, that is, the support shaft 80 and the first thread take-up driving rod 31 and the second thread take-up driving rod 32 sleeved on the support shaft 80 reciprocate together along the axial direction of the support shaft 80. In this way, the thread take-up driving assembly 30 can also be switched between the working position and the static position.

[0061] In the third specific embodiment, Fig.10 As shown, the first thread take-up driving rod 31 includes a detachably connected first portion 3101 and a second portion 3102. The first portion 3101 includes a power input end 311, and the second portion 3102 is sleeved on the support shaft 80.

[0062] The clutch mechanism 40 allows the first part 3101 to move closer to the second part 3102 and connect them into one, and the power input end 311 of the first thread take-up driving rod 31 cooperates with the thread take-up cam 20; the clutch mechanism 40 allows the first part 3101 to move away from the second part 3102 and disassemble into two parts, and the power input end 311 of the first thread take-up driving rod 31 disengages from the thread take-up cam 20. In this way, the thread take-up driving assembly 30 can be switched between the working position and the static position.

[0063] Alternatively, the clutch mechanism 40 allows the second part 3102 to move closer to the first part 3101 that cooperates with the thread take-up cam 20 and be connected as one; the clutch mechanism 40 allows the second part 3102 to move away from the first part 3101 that cooperates with the thread take-up cam 20 and be disassembled into two parts. In this way, the thread take-up drive assembly 30 can also be switched between the working position and the static position.

[0064] Of course, it is understandable that the second thread take-up driving rod 32 can be the same as the first thread take-up driving rod 31, and the second thread take-up driving rod 32 includes two detachably connected parts, referring to the above description, so it is not repeated. At the current moment, the second thread take-up driving rod 32 includes two detachably connected parts, and the first thread take-up driving rod 31 is a complete rod, so that the thread take-up driving assembly 30 can also be switched between the working position and the static position.

[0065] The first part 3101 is provided with a first matching portion, and the second part 3102 is provided with a second matching portion. The first matching portion matches with the second matching portion, and the first part 3101 and the second part 3102 are inserted or snap-fitted.

[0066] The following embodiments are described by taking the first specific embodiment as an example, that is, the clutch mechanism 40 enables the first thread take-up driving rod 31 and the second thread take-up driving rod 32 to reciprocate together along the axial direction of the support shaft 80 .

[0067] Specifically, Figure 2 and Figure 4 As shown, the clutch mechanism 40 includes a clutch sleeve 41, a shift fork 42 and a positioning sleeve 43. The clutch sleeve 41 is sleeved on the support shaft 80. Figure 8 As shown, the contact area between the shift fork 42 and the clutch sleeve 41 can be U-shaped or V-shaped, and the slot 411 of the clutch sleeve 41 is an annular groove. The shift fork 42 can be inserted and matched with the slot 411. In this way, the shift fork 42 can reciprocate along the axis direction of the support shaft 80 through the pneumatic push rod 60, the hydraulic push rod, the electric push rod, or other suitable mechanisms, thereby driving the clutch sleeve 41 to reciprocate along the axis direction of the support shaft 80.

[0068] At the same time, the slot 411 can rotate around the axis of the support shaft 80. In other words, Figure 6 As shown, the first thread take-up driving rod 31 and the second thread take-up driving rod 32 move rightward along the axial direction of the support shaft 80, the power input end 311 of the first thread take-up driving rod 31 is inserted into the cam groove 21 of the thread take-up cam 20, and the power output end 321 of the second thread take-up driving rod 32 is inserted into the groove of the thread take-up rod 10. At this moment, Figure 8As shown, the rotating support shaft 80 drives the clutch sleeve 41 to rotate, and the slot 411 rotates relative to the axis of the support shaft 80. Since the contact area between the shift fork 42 and the clutch sleeve 41 is U-shaped, the shift fork 42 and the rotating clutch sleeve 41 will not interfere with each other, and the U-shape can guide the rotating clutch sleeve 41, so that the slot 411 of the clutch sleeve 41 can rotate around the axis of the support shaft 80.

[0069] In addition, if Figure 6 As shown, the movable end of the pneumatic push rod 60 is connected to the shift fork 42 and the positioning sleeve 43, wherein the pneumatic push rod 60 is mounted on the support frame 70. When the shift fork 42 moves rightward along the axial direction of the support shaft 80, the positioning sleeve 43 abuts against the support frame 70, thereby further limiting the distance of the shift fork 42 moving rightward, thereby improving the distance accuracy of the shift fork 42 moving rightward.

[0070] In some embodiments of the present invention, the thread taking-up mechanism further comprises a rotation-stopping assembly 50. When the thread taking-up drive assembly 30 is in a stationary position, the rotation-stopping assembly 50 cooperates with the support shaft 80 to stop rotation.

[0071] In the specific implementation, Figure 2 and Figure 4 As shown, the anti-rotation assembly 50 includes a first anti-rotation member 51 and a first fixing member 52. The first fixing member 52 can be connected to the housing of the computer embroidery machine, and the first anti-rotation member 51 is connected to the support shaft 80. The first fixing member 52 and the first anti-rotation member 51 stop and cooperate to prevent the support shaft 80 from rotating.

[0072] In this way, after the power input end 311 of the first thread take-up driving rod 31 is separated from the cam groove 21 of the thread take-up cam 20, it is still arranged opposite to the cam groove 21, and there is only a gap d between the two. When the clutch mechanism 40 makes the power input end 311 of the first thread take-up driving rod 31 and the thread take-up cam 20 match again, the power input end 311 of the first thread take-up driving rod 31 can be accurately inserted into the cam groove 21 of the thread take-up cam 20, ensuring that the power input end 311 of the first thread take-up driving rod 31 and the thread take-up cam 20 are accurately matched.

[0073] Of course, it is understood that the anti-rotation assembly 50 can also present other structures, such as Fig. 9 As shown, the anti-rotation assembly 50 includes a second anti-rotation member 53 and a second fixing member (not shown). The second fixing member can be connected to the housing of the computer embroidery machine, and the second anti-rotation member 53 is connected to the support shaft 80. The second anti-rotation member 53 is provided with a flat surface portion 531, and the flat surface portion 531 is in surface contact with the second fixing member to prevent the support shaft 80 from rotating.

[0074] The computer embroidery machine according to the embodiment of the second aspect of the utility model includes the thread taking-up mechanism in the first aspect.

[0075] The computer embroidery machine has the advantages of the thread take-up mechanism mentioned above. When the thread take-up drive assembly 30 is in the working position, the power input end 311 of the first thread take-up drive rod 31 cooperates with the thread take-up cam 20; when the thread take-up drive assembly 30 is in the static position, the power input end 311 of the first thread take-up drive rod 31 is disengaged from the thread take-up cam 20. When the computer embroidery machine starts the inter-head embroidery function, the thread take-up rod 10 corresponding to the closed head can stop moving, so as to avoid the thread take-up rod 10 corresponding to the closed head from making meaningless movements and avoid the embroidery thread on the thread take-up rod 10 corresponding to the closed head from accidentally breaking.
