[0047] The lifting fork 50 is movably disposed on the frame body 10 , and the lifting fork 50 reciprocates in the vertical direction.

[0048] The motion conversion mechanism 40 connects the lifting fork 50 and the rope mouth 60 so that the rope mouth 60 reciprocates between a first working limit position and a second working limit position, and the direction from the first working limit position to the second working limit position forms a preset angle with the vertical direction.

[0049] It should be noted that if Figure 15-17 As shown, in actual application, the computer embroidery machine includes a thread wheel replacement device and a machine head 200, the thread wheel replacement device includes a storage mechanism 400 and a manipulator 300, the storage mechanism 400 has a plurality of spaced storage spaces, and the storage spaces are used to store the thread wheel frame 100. The manipulator 300 is used to move the thread wheel frame 100.

[0050] The machine head 200 includes a reel frame mounting plate 201 and a movable sleeve 202, and the reel frame mounting plate 201 is provided with an inserting hole 2011. The movable sleeve 202 is located below the reel frame mounting plate 201, and the movable sleeve 202 can move back and forth close to and away from the reel frame mounting plate 201, that is, the movable sleeve 202 reciprocates in the vertical direction.

[0051] like Figure 1-Figure 4 As shown, the reel frame 100 includes a frame body 10, a lifting fork 50, a pivot shaft 20, a wheel body 30, a motion conversion mechanism 40 and a rope mouth 60. The frame body 10 is provided with a first latch 11 and a second latch 12, one of which is inserted and matched with the insertion hole 2011 to realize the installation of the reel frame 100 on the head of the computer embroidery machine; the other is inserted and matched with the manipulator 300 to realize the manipulator 300 to grab the reel frame 100, so that the manipulator can freely move the reel frame 100.

[0052] A rope is wound around the wheel body 30. The wheel body 30 is sleeved on the pivot shaft 20. The thread wheel frame 100 cooperates with the embroidery needle of the machine head 200 to realize rope embroidery.

[0053] The lifting fork 50 is located below the frame 10, and the lifting fork 50 can move back and forth close to and away from the frame 10. The lifting fork 50 includes a U-shaped fork 51, and the U-shaped fork 51 cooperates with the above-mentioned movable sleeve 202, and then the movable sleeve 202 drives the lifting fork 50 to reciprocate, so that the lifting fork 50 can move close to and away from the frame 10, that is, the lifting fork 50 can reciprocate in the vertical direction.

[0054] The motion conversion mechanism 40 connects the lifting fork 50 and the rope mouth 60 so that the rope mouth 60 reciprocates between the first working limit position and the second working limit position. It should be noted that in actual application, the rope mouth 60 includes an initial position (such as Figure 8 and Fig.14), the first working limit position (such as Figure 6 and Fig.12 ), the second working limit position (such as Figure 7 and Fig.13 ). The "working limit position" here refers to the position of a motion cycle, not the highest or lowest position in space.

[0055] The direction from the first working limit position to the second working limit position can be the front-to-back direction, and the direction from the first working limit position to the second working limit position can be close to the front-to-back direction, that is, the direction from the first working limit position to the second working limit position forms an angle α with the front-to-back direction, and α can be 5°, 10°, 15°, etc., which are not listed one by one in this embodiment.

[0056] Similarly, the direction from the first working limit position to the second working limit position can be the left-right direction, and the direction from the first working limit position to the second working limit position can be close to the left-right direction, that is, the direction from the first working limit position to the second working limit position forms an angle β with the left-right direction, and β can be 5°, 10°, 15°, etc., which are not listed one by one in this embodiment.

[0057] That is to say, the direction from the first working limit position to the second working limit position can be perpendicular to the vertical direction, or can be non-perpendicular to form a preset angle, and the size of the preset angle can be selected by those skilled in the art according to actual conditions. In this way, the rope mouth 60 can move in the horizontal direction, and the movement trajectory of the rope mouth 60 can be a straight line or an arc.

[0058] The working principle of the computer embroidery machine, wherein the thread reel frame 100 with a mouth and the thread reel frame 100 with a rope mouth 60 are located in each storage space on the storage mechanism 400:

[0059] When the computer embroidery machine needs to perform rope embroidery, the manipulator 300 grabs the thread reel frame 100 with the rope mouth 60 to the machine head 200 and installs it on the machine head 200, and then performs rope embroidery; when the computer embroidery machine needs to perform ribbon embroidery, the manipulator 300 places the thread reel frame 100 with the rope mouth 60 on the storage mechanism 400 through the manipulator 300, and then the manipulator 300 grabs the thread reel frame 100 with the mouth from the storage mechanism 400 to the machine head 200, and installs it on the machine head 200, and then performs ribbon embroidery. In this way, the computer embroidery machine has the functions of rope embroidery and ribbon embroidery at the same time, which greatly improves the applicability of the computer embroidery machine and reduces the production cost of the equipment.

[0060] In some embodiments of the present invention, the motion conversion mechanism 40 includes a connecting rod mechanism.

[0065] The sliding member 46 is connected to the lifting fork 50, and the sliding member 46 is slidably matched with the conversion hole to switch the rope mouth 60 between the first working limit position and the second working limit position.

[0066] Furthermore, the body includes a conversion disk 49 and a support disk 47, and the conversion disk 49 is provided with the above-mentioned straight hole 491. The conversion disk 49 is detachably connected to the support disk 47 to adjust the acute angle γ to the acute angle δ. In this way, the inclination of the straight hole 491 can be adjusted, and then the swing amplitude of the rope mouth 60 can be adjusted. The larger the swing amplitude, the longer the time of the entire cycle, and the smaller the swing amplitude, the shorter the time of the entire cycle. Those skilled in the art can select a suitable swing amplitude according to needs.

[0067] In addition, the conversion disk 49 can be detachably connected to the support disk 47, which can be understood as the conversion disk 49 and the support disk 47 can be threadedly connected, the conversion disk 49 and the support disk 47 can be inserted and connected, the conversion disk 49 and the support disk 47 can be snap-connected, etc., which are not listed one by one in this embodiment.
