[0025] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments:

[0026] like Figure 1-5As shown, an automatic bobbin changing device for an automatic fabric striping machine includes a frame 1, a clamping mechanism 2, and a bobbin storage mechanism 3 for conveying bobbins. The clamping mechanism 2 is located between the bobbin storage mechanism 3 and the sewing machine 4 and is used to change bobbins. The clamping mechanism 2 includes a first motor 21 and an elastic clamping swing arm 22 located within the frame 1, a clamping swing arm 23 rotatably mounted on the output shaft 211 of the first motor 21, and a second motor 24 mounted on the first motor 21. The elastic clamping swing arm 22 is equipped with a gripping block 25 for gripping the bobbin, and the clamping swing arm 23 is equipped with a gripping block 25 for gripping the bobbin. A clamping block 26, which cooperates with the gripping block 25, forms a clamping space 200 for clamping the bobbin case. An elastic clamping swing arm 22 is linked to the output shaft 211 of the first motor 21. The output shaft 211 drives the elastic clamping swing arm 22 to rotate relative to the clamping swing arm 23, allowing the elastic clamping swing arm 22 and the clamping swing arm 23 to have a released state separated from each other and a gripping state closed to each other. The clamping swing arm 23 is linked to the second motor 24, which drives the clamping swing arm 23 to reciprocate between the bobbin case storage mechanism 3 and the sewing machine 4. The gripping block 25 has a clamping inclined surface 251 for clamping the bobbin case on the side facing the clamping block 26, and the clamping block 26 has a clamping inclined surface 261 for clamping the bobbin case on the side facing the gripping block 25. A clamping space 200 is formed between the clamping inclined surfaces 251 and 261. By clamping the shuttle housing with the gripping ramps of the gripping block and the clamping ramps 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 gripping block 25 has a gripping ramp 252 on the side facing away from the clamping block 26, which cooperates with the shuttle housing. The gripping ramp serves as a guide and can open the elastic locking tab of the shuttle housing, thereby ensuring that the gripping block can reliably grip the elastic locking tab of the shuttle housing. Two limiting pieces 27 are provided on both sides of the clamping block 26, forming a limiting space 270 between the two limiting pieces 27 and the clamping block 26 to accommodate the gripping block 25. The limiting pieces serve a limiting function, ensuring that the gripping block and the clamping block can reliably clamp the shuttle housing.

[0027] like Figure 2 and 3As shown, a large pulley 28 is rotatably mounted on the output shaft 211 of the first motor 21, and the clamping swing arm 23 is linked to the large pulley 28. A small pulley 29 is mounted on the shaft of the second motor 24, and a synchronous belt 30 connects the large pulley 28 and the small pulley 29. The second motor drives the clamping swing arm to swing through the large pulley, the small pulley, and the synchronous belt, ensuring that the second motor can reliably drive the clamping swing arm to move. The shuttle shell storage mechanism 3 includes a third motor 31 and a material carrier plate 32 slidably mounted on the frame 1. The material carrier plate 32 is provided with multiple material carrier slots 321 for conveying shuttle shells. The third motor 31 is mounted on the frame 1 and is used to drive the material carrier plate 32 to reciprocate along the width direction of the frame 1. The shuttle shell storage mechanism can realize the automatic conveying of multiple shuttle shells, thereby improving the efficiency of the automatic shuttle shell changing device. A rack 33 is provided along the length direction of the material carrier plate 32, and a gear 34 that meshes with the rack 33 is provided on the motor shaft of the third motor 31. The third motor drives the material carrier plate via gears, ensuring more reliable and stable transmission between the third motor and the material carrier plate. A guide rail 321 is provided on the material carrier plate 32, and a slider 11 is provided on the frame 1. The guide rail 321 is slidably disposed within the guide rail groove 111 of the slider 11. The material carrier plate is slidably disposed on the slider of the frame via the guide rail, thus ensuring reliable movement of the material carrier plate on the frame.

[0028] like Figure 1-3 As shown, the first motor 21 is slidably mounted inside the frame 1, and a cylinder 12 is installed inside the frame 1 to drive the first motor 21 to reciprocate along the length of the frame 1. The first motor is pneumatically driven to slide within the frame. When changing the shuttle case, the pneumatically driven first motor moves outward, driving the elastic clamping arm to extend out of the frame to perform the shuttle case replacement action. After the shuttle case replacement is completed, the cylinder drives the first motor to move inward, driving the elastic clamping arm to retract back into the frame. A small slider 13 is mounted on the first motor 21, and a small guide rail 14 is provided along the length of the frame 1. The small slider 13 is slidably mounted on the small guide rail 14. A push plate 15 is linked to the piston rod 121 of the cylinder 12, and the push plate 15 is connected to the first motor 21, forming a linkage between the first motor 21 and the push plate 15. The first motor slides on a small guide rail via a small slider, which ensures that the cylinder can reliably drive the first motor to operate, thereby improving the working reliability of the automatic shuttle changer.

[0029] The clamping mechanism employs a double-clamping swing arm design. Through the elastic clamping swing arms and their reciprocating oscillation, the bobbin case is automatically transported between the bobbin case storage mechanism and the sewing machine, thus enabling automatic bobbin case replacement. A dual-motor design is also used. The first motor drives the elastic clamping swing arms to perform closing and opening actions, thereby enabling the clamping mechanism to grasp and release the bobbin case. The second motor drives the clamping swing arms to reciprocate between the bobbin case storage mechanism and the sewing machine, thus achieving automatic bobbin case replacement.

[0030] The above description is only one embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model; the scope of protection of the present utility model is defined by the claims in the claims, and all equivalent changes and modifications made in accordance with the utility model are within the scope of protection of the present utility model patent.
