[0054] As Figure 1 shown, in the left-right direction, the thread taking-up assembly is arranged on the main beam.

[0055] At least referring to Figures 1 - 12 shown, the thread taking-up assembly includes: a first thread taking-up device and a second thread taking-up device.

[0056] The first thread taking-up device includes a first thread taking-up pull rod 11 and at least one first unit 100; the first unit 100 includes at least one first thread taking-up driving component 101, at least one first thread taking-up cam 102, and at least one first thread taking-up rod component 103.

[0057] The second thread taking-up device includes a second thread taking-up pull rod 21 and at least one second unit 200. The second unit 200 includes at least one second thread taking-up driving component 201, at least one second thread taking-up cam, and at least one second thread taking-up rod component. The second thread taking-up driving component 201, the second thread taking-up cam, and the second thread taking-up rod component correspond to each other one by one.

[0058] As Figures 2 - 9As shown in the figure, each head corresponds to a first thread take-up driving component 101, a first thread take-up cam 102, and a first thread take-up lever assembly 103. The head corresponding to the first thread take-up driving component 101, the first thread take-up cam 102, and the first thread take-up lever assembly 103 is defined as the first head. When the first unit 100 is provided with one first thread take-up driving component 101, one first thread take-up cam 102, and one first thread take-up lever assembly 103, each first unit 100 corresponds to one first head; or, when the first unit 100 is provided with two first thread take-up driving components 101, two first thread take-up cams 102, and two first thread take-up lever assemblies 103, each first unit 100 corresponds to two first heads; or, when the first unit 100 is provided with three first thread take-up driving components 101, three first thread take-up cams 102, and three first thread take-up lever assemblies 103, each first unit 100 corresponds to three first heads; or, when the first unit 100 is provided with four first thread take-up driving components 101, four first thread take-up cams 102, and four first thread take-up lever assemblies 103, each first unit 100 corresponds to four first heads;...

[0059] Similarly, as Figures 2 - 9 shown in the figure, each head corresponds to a second thread take-up driving component 201, a second thread take-up cam, and a second thread take-up lever assembly. The head corresponding to the second thread take-up driving component 201, the second thread take-up cam, and the second thread take-up lever assembly is defined as the second head. When the second unit 200 is provided with one second thread take-up driving component 201, one second thread take-up cam, and one second thread take-up lever assembly, each second unit 200 corresponds to one second head; or, when the second unit 200 is provided with two second thread take-up driving components 201, two second thread take-up cams, and two second thread take-up lever assemblies, each second unit 200 corresponds to two second heads; or, when the second unit 200 is provided with three second thread take-up driving components 201, three second thread take-up cams, and three second thread take-up lever assemblies, each second unit 200 corresponds to three second heads; or, when the second unit 200 is provided with four second thread take-up driving components 201, four second thread take-up cams, and four second thread take-up lever assemblies, each second unit 200 corresponds to four second heads;...

[0060] Among them, the first thread take-up pull rod 11 is the same as the second thread take-up pull rod 21. As Figures 10 - 12 shown in the figure, the first thread take-up pull rod 11 can reciprocate in the left-right direction.

[0061] The first thread take-up lever assembly 103 is the same as the second thread take-up lever assembly. Taking the first thread take-up lever assembly 103 as an example:

[0062] As Figures 10 - 12As shown, the first thread picking lever assembly 103 includes a plurality of first thread picking levers 1031 arranged in the left-right direction, and the first thread picking levers 1031 correspond to the sewing needles of the first machine head one by one. The second thread picking lever assembly includes a plurality of second thread picking levers arranged in the left-right direction.

[0063] The first thread picking cam 102 is the same as the second thread picking cam. As Figures 10 - 12 shown, each first machine head is provided with a first thread picking cam 102; each second machine head is provided with a second thread picking cam. The first thread picking cam 102 and the second thread picking cam are installed on the upper shaft. When the upper shaft rotates, the first thread picking cam 102 and the second thread picking cam are driven to rotate simultaneously.

[0064] The first thread picking drive assembly 101 is the same as the second thread picking drive assembly 201. Taking the first thread picking drive assembly 101 as an example:

[0065] In a specific embodiment, as Figures 10 - 12 shown, the first thread picking drive assembly 101 includes a dial block 13, a thread picking assembly 15, a guide shaft 19, a support shaft 17 and a clutch mechanism. The thread picking assembly 15 includes a first thread picking drive rod 151 and a second thread picking drive rod 152; the clutch mechanism includes a clutch sleeve 18 and a fork 14.

[0066] The upper end of the dial block 13 is inserted and fitted with the upper end of the fork 14. The lower end of the fork 14 is arc-shaped, and the lower end of the fork 14 is inserted and fitted with the clutch sleeve 18. The clutch sleeve 18 is sleeved on the support shaft 17. Among them, the dial block 13 is sleeved on the first thread picking pull rod 11. The first thread picking pull rod 11 reciprocates in the left-right direction. By driving the dial block 13, the fork 14 can reciprocate in the left-right direction. Furthermore, the clutch sleeve 18 can reciprocate in the left-right direction, so that the support shaft 17 can reciprocate in the left-right direction. At the same time, since the lower end of the fork 14 is arc-shaped, when the support shaft 17 rotates, the clutch sleeve 18 can rotate and will not interfere with the lower end of the fork 14 to avoid affecting the rotation of the support shaft 17.

[0067] The first thread picking drive rod 151 and the second thread picking drive rod 152 are respectively sleeved on the support shaft 17. In this way, the first thread picking drive rod 151 and the second thread picking drive rod 152 can also reciprocate in the left-right direction. The power input end 1511 of the first thread picking drive rod 151 is used to cooperate with the cam groove 1021 of the first thread picking cam 102; the power input end 1521 of the second thread picking drive rod 152 is used to cooperate with the first thread picking lever 1031 of the first thread picking lever assembly 103, so that the first thread picking lever 1031 can swing.

[0068] As Figures 10 - 12As shown in the figure, the first thread take-up driving rod 151 has a working position and a stationary position. The first thread take-up pull rod 11 causes the first thread take-up driving rod 151 to switch between the working position and the stationary position. When the first thread take-up driving rod 151 is in the working position, the power input end 1511 of the first thread take-up driving rod 151 cooperates with the cam groove 1021 of the first thread take-up cam 102. At the current position, due to the rotation of the first thread take-up cam 102, the first thread take-up driving rod 151 causes the support shaft 17 to rotate a preset central angle along its axis, and the support shaft 17 causes the second thread take-up driving rod 152 to swing. At the current moment, since the power input end 1521 of the second thread take-up driving rod 152 corresponds to the groove 10311 of the first thread take-up rod 1031, the power input end 1521 of the second thread take-up driving rod 152 is inserted into the groove 10311 of the first thread take-up rod 1031, and the power input end 1521 of the second thread take-up driving rod 152 causes the first thread take-up rod 1031 to swing.

[0069] When the first thread take-up driving rod 151 is in the stationary position, the power input end 1511 of the first thread take-up driving rod 151 is disengaged from the cam groove 1021 of the first thread take-up cam 102. At the current position, the first thread take-up cam 102 rotates, but the first thread take-up driving rod 151 cannot swing. Correspondingly, the power input end 1521 of the second thread take-up driving rod 152 causes the first thread take-up rod 1031 not to swing. At the same time, the power input end 1521 of the second thread take-up driving rod 152 is located between two adjacent first thread take-up rods 1031, and the power input end 1521 of the second thread take-up driving rod 152 does not correspond to the groove 10311 of the first thread take-up rod 1031.

[0070] Furthermore, as Figures 10 - 12 shown in the figure, the first thread take-up driving assembly 101 further includes a rotation stopping assembly 16, and the rotation stopping assembly 16 includes a first rotation stopping member 161 and a first fixing member 162. The first rotation stopping member 161 is sleeved on the support shaft 17, and the first fixing member 162 can be installed on the inner surface of the housing wall of the first machine head.

[0071] When the support shaft 17 moves from right to left, the first thread take-up driving rod 151 switches from the working position to the stationary position. At the same time, the first rotation stopping member 161 and the first fixing member 162 are in a stopping fit to prevent the support shaft 17 from rotating. With this setting, after the power input end 1511 of the first thread take-up driving rod 151 is disengaged from the cam groove 1021 of the first thread take-up cam 102, it is still disposed opposite to the cam groove 1021. When the support shaft 17 moves from left to right, the first thread take-up driving rod 151 switches from the disengaged position to the working position, and the power input end 1511 of the first thread take-up driving rod 151 can accurately be inserted into the cam groove 1021 again.

[0072] Optionally, when there are multiple first units 100 and multiple second units 200. The first unit 100 includes a first thread picking driving assembly 101, a first thread picking cam 102 and a first thread picking rod assembly 103; the second unit 200 includes a second thread picking driving assembly 201, a second thread picking cam and a second thread picking rod assembly; the second unit 200 and the first unit 100 are arranged alternately in the left-right direction.

[0073] As Figures 1 - 3 shown, each first unit 100 corresponds to a first machine head; each second unit 200 corresponds to a second machine head.

[0074] The thread picking assembly further includes a connecting frame 30, and the connecting frame 30 is provided with a first through hole capable of passing through the first thread picking pull rod 11 and a second through hole capable of passing through the second thread picking pull rod 21. A connecting frame 30 is provided on each first machine head, and a connecting frame 30 is provided on each second machine head. In this way, the connecting frame 30 has a supporting effect on the first thread picking pull rod 11 and the second thread picking pull rod 21. At the same time, the connecting frame 30 has a guiding effect on the first thread picking pull rod 11 and the second thread picking pull rod 21, which helps the first thread picking pull rod 11 and the second thread picking pull rod 21 to reciprocate in the left-right direction.

[0075] The first thread picking pull rod 11 and the second thread picking pull rod 21 are arranged in parallel, and the lengths of the first thread picking pull rod 11 and the second thread picking pull rod 21 both extend in the left-right direction. A plurality of blocks 13 of the first thread picking driving assembly 101 are arranged at equal intervals on the first thread picking pull rod 11. A plurality of blocks of the second thread picking driving assembly 201 are arranged at equal intervals on the second thread picking pull rod 21. The blocks 13 of the first thread picking driving assembly 101 and the blocks of the second thread picking driving assembly 201 are arranged alternately in the left-right direction.

[0076] Since the first thread picking cam 102 and the second thread picking cam rotate simultaneously, when the first thread picking pull rod 11 reciprocates in the left-right direction, the first thread picking pull rod 11 can make the first thread picking driving rod 151 of the first thread picking driving assembly 101 in the working position, and the power input end 1511 of the first thread picking driving rod 151 cooperates with the cam groove 1021 of the first thread picking cam 102, so that the first thread picking rod 1031 on the first thread picking rod assembly 103 can swing; and at the current moment, the second thread picking pull rod 21 can make the corresponding first thread picking driving rod of the second thread picking driving assembly 201 in the static position, and the power input end of the first thread picking driving rod is disengaged from the cam groove of the second thread picking cam, so that the second thread picking rod on the second thread picking rod assembly remains stationary, avoiding meaningless movement of the second thread picking rod and accidental breakage of the embroidery thread on the second thread picking rod.

[0077] Of course, optionally, when there are multiple first units 100 and multiple second units 200. The first unit 100 includes two first thread-picking driving components 101, two first thread-picking cams 102 and two first thread-picking rod components 103; the second unit 200 includes two second thread-picking driving components 201, two second thread-picking cams and two second thread-picking rod components; the second unit 200 and the first unit 100 are alternately arranged in the left-right direction.

[0078] As Figure 4 and Figure 5 shown, each first unit 100 corresponds to two first machine heads; each second unit 200 corresponds to two second machine heads.

[0079] Each first unit 100 includes the blocks 13 of two first thread-picking driving components 101 located on the first thread-picking pull rod 11, and the blocks 13 of multiple above-mentioned two first thread-picking driving components 101 are arranged at equal intervals on the first thread-picking pull rod 11. Each second unit 200 includes the blocks of two second thread-picking driving components 201 located on the second thread-picking pull rod 21, and the blocks of multiple above-mentioned two second thread-picking driving components 201 are arranged at equal intervals on the second thread-picking pull rod 21. The blocks 13 of the two first thread-picking driving components 101 and the blocks of the two second thread-picking driving components 201 are alternately arranged in the left-right direction.

[0080] Optionally, when there are multiple first units 100 and multiple second units 200. The first unit 100 includes one first thread-picking driving component 101, one first thread-picking cam 102 and one first thread-picking rod component 103; the second unit 200 includes two second thread-picking driving components 201, two second thread-picking cams and two second thread-picking rod components; or,

[0081] The first unit 100 includes two first thread-picking driving components 101, two first thread-picking cams 102 and two first thread-picking rod components 103; the second unit 200 includes one second thread-picking driving component 201, one second thread-picking cam and one second thread-picking rod component;

[0082] The second unit 200 and the first unit 100 are alternately arranged in the left-right direction.

[0083] As Figure 6 and Figure 7 shown, each first unit 100 corresponds to one first machine head; each second unit 200 corresponds to two second machine heads.

[0084] Each second unit 200 includes a block of two second thread picking driving components 201 located on the second thread picking pull rod 21, and a plurality of such blocks of the two second thread picking driving components 201 are arranged at equal intervals on the second thread picking pull rod 21. A block 13 of a first thread picking driving component 101 and the blocks of the two second thread picking driving components 201 are arranged alternately in the left-right direction.

[0085] Optionally, when there is one first unit 100 and one second unit 200.
