Therefore, the directional and positional terms used are for the purpose of explaining and understanding this utility model, and not for limiting the scope of protection of this utility model.

[0021] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments: like Figure 1-5 As shown, an automatic bobbin changing device for an automatic fabric striping machine includes a frame 1, a turntable feeding mechanism 2 and a clamping mechanism 3 mounted on the frame 1 for conveying bobbins. The clamping mechanism 3 is located between the turntable feeding mechanism 2 and the sewing machine 4 for changing bobbins between the turntable feeding mechanism 2 and the sewing machine 4. The clamping mechanism 3 includes a slider 31 slidably mounted in the frame 1, a rotating shaft 32 rotatably mounted on the slider 31, a pneumatic mechanism 33 mounted in the frame 1 for driving the rotating shaft 32 to rotate, and an elastic swing arm linked to the rotating shaft 32. The clamping swing arm 35, which is rotatably mounted on the rotating shaft 32, and the first cylinder 36, which is mounted on the slider 31, and the second cylinder 37, which drives the slider 31 to slide back and forth along the length of the mechanism frame 1, are connected in a linkage with the first cylinder 36. The first cylinder 36 drives the clamping swing arm 35 to swing back and forth between the turntable feeding mechanism 2 and the sewing machine 4. The pneumatic mechanism 33 drives the elastic swing arm 34 to rotate relative to the clamping swing arm 35 through the rotating shaft 32, so that the elastic swing arm 34 and the clamping swing arm 35 have a released state that is separated from each other and a gripping state that is closed to each other.

[0022] like Figure 3 , 4As shown, the pneumatic mechanism 33 includes a third cylinder 331, a drive sleeve 332 linked to a rotating shaft 32, and a ball bearing sleeve 333 slidably mounted on the drive sleeve 332. The ball bearing sleeve 333 is linked to the third piston rod 3311 of the third cylinder 331, and a bearing 334 is provided between the third piston rod 3311 and the ball bearing sleeve 333. Balls 335 are mounted on the ball bearing sleeve 333. An inclined groove 3321 is provided on the outer peripheral wall of the drive sleeve 332 for the balls 335 to roll. The ball bearing sleeve 333 drives the balls 335 to reciprocate within the inclined groove 3321. The piston rod of the third cylinder drives the balls to reciprocate on the drive sleeve via the ball bearing sleeve. The drive sleeve drives the rotating shaft to rotate, and the rotating shaft drives the elastic swing arm to move. This converts the linear motion of the third piston rod of the third cylinder into the rotational motion of the rotating shaft. This structural design is simpler, lower in cost, and smaller in size. A support plate 38 is provided on the slider 31, and a first cylinder 36 is mounted on the support plate 38. A drive shaft 362 is linked to the first piston rod 361 of the first cylinder 36, and one end of the drive shaft 362 is rotatably connected to the clamping arm 35. The first cylinder drives the clamping arm to rotate through the drive shaft, which helps to improve the working reliability of the clamping mechanism.

[0023] like Figure 1-3 As shown, the turntable feeding mechanism 2 includes a drive slider 21 slidably disposed within the mechanism frame 1, a support member 22 linked to the drive slider 21, a motor 23 mounted on the support member 22, and a rotating disk 24 linked to the output shaft of the motor 23. Multiple carriers 25 for conveying shuttle shells are arranged in a circular array on the rotating disk 24. The turntable feeding mechanism adopts a rotating disk structure design, which is simple and also helps to improve the feeding efficiency of the turntable feeding mechanism. A fifth cylinder 26 is disposed on the mechanism frame 1. The fifth piston rod 261 of the fifth cylinder 26 is connected to the support member 22. The fifth piston rod 261 drives the drive slider 21 to slide back and forth along the length direction of the mechanism frame 1 through the support member 22. The second piston rod 371 of the second cylinder 37 is connected to the drive slider 21. A drive plate 39 connects the second cylinder 37 and the slider 31. The fifth cylinder pushes the turntable feeding mechanism and clamping mechanism to the working position or pulls them back to the non-working position through the support member, thereby realizing the extension and retraction of the turntable feeding mechanism and clamping mechanism, which helps to improve the working reliability of the automatic shuttle changing device.

[0024] like Figure 1 , 2As shown in Figures 5 and 6, the elastic swing arm 34 is provided with a gripping block 341 for gripping the bobbin case, and the clamping swing arm 35 is provided with a clamping block 351 that cooperates with the gripping block 341. A clamping space 300 for clamping the bobbin case is formed between the gripping block 341 and the clamping block 351. By gripping and releasing the bobbin case through the gripping block of the elastic swing arm and the clamping block of the clamping swing arm, the clamping mechanism can reliably change the bobbin case between the turntable feeding mechanism and the sewing machine. The gripping block 341 has a clamping inclined surface 3411 for clamping the bobbin case on the side facing the clamping block 351, and the clamping block 351 has a clamping inclined surface 3511 for clamping the bobbin case on the side facing the gripping block 341. A clamping space 300 is formed between the clamping inclined surface 3411 and the clamping inclined surface 3511. By clamping the shuttle housing with the gripping inclined surface of the gripping block and the clamping inclined surface of the clamping block, the contact area between the gripping block, the clamping block and the shuttle housing can be effectively increased, thereby ensuring that the gripping block and the clamping block can reliably clamp the shuttle housing. The limiting piece can play a limiting role to ensure that the gripping block and the clamping block can reliably clamp the shuttle housing. A fixing block 352 is provided on the clamping swing arm 35, and a clamping block 351 is provided on one side of the fixing block 352. A limiting piece 353 is provided on one side of the clamping block 351. The fixing block 352, the limiting piece 353 and the clamping inclined surface 3511 form a receiving space 3000 for accommodating the gripping block 341. The clamping block and the limiting piece are integrated on the fixing block, which facilitates the assembly of the clamping block and the clamping swing arm, and the limiting piece can play a limiting role to ensure that the clamping mechanism can reliably clamp the shuttle housing. The gripping block 341 has a gripping ramp 3412 on the side opposite to the clamping block 351 that mates with the shuttle case. The gripping block opens the locking piece of the shuttle case by gripping ramp, thereby ensuring that the gripping block can reliably clamp the shuttle case onto the clamping block.

[0025] like Figure 3 As shown, a guide slider 311 is linked to the slider 31, and a guide rail 11 is provided along its length inside the mechanism frame 1. The guide slider 311 is slidably mounted on the guide rail 11. The slider is slidably mounted on the guide rail inside the mechanism frame via the guide slider, thereby ensuring that the slider can move reliably within the mechanism frame. During operation, the second cylinder drives the elastic swing arm and the clamping swing arm to move along the length of the mechanism frame via the slider, thereby realizing the clamping mechanism's gripping and releasing of the shuttle case.

[0026] The clamping mechanism adopts a double-swing arm structure design. Through the reciprocating swing of the elastic swing arm and the clamping swing arm, the bobbin case is automatically transported between the turntable feeding mechanism and the sewing machine, thus enabling automatic bobbin case replacement. It employs a pneumatic drive structure, which is simple in design and low in cost. The third cylinder drives the elastic swing arm and the clamping swing arm to perform closing and opening actions, thereby realizing the clamping mechanism's gripping and releasing of the bobbin case. The elasticity of the swing arm increases the clamping force of the clamping mechanism on the bobbin case, which helps improve the working reliability of the clamping mechanism. The first cylinder drives the clamping swing arm to reciprocate between the turntable feeding mechanism and the sewing machine, thus realizing automatic bobbin case replacement and effectively improving the production efficiency of the striping machine.
