[0003] In the field of wearable equipment that needs to be adjusted frequently (such as sports protective gear, outdoor shoes and boots, tactical backpacks, etc.), the combination of buckles and Velcro is widely used because of its quick adjustment advantage. The typical structure of this type of product is: the end of the Velcro forms a closed loop system through the buckle, and the free end is hemmed to prevent the fibers from spreading.

[0049] For feeding the buckle ring B, a ring loading assembly 5 is provided on the body of the working end of the process turntable 2. The ring loading assembly 5 includes a ring conveying frame 51, a ring feeding head 52 and a ring conveying cylinder 53. The ring conveying frame 51 is inclined and the buckle ring B is placed. The ring feeding head 52 is installed at the discharge end of the ring conveying frame 51 through the ring conveying cylinder 53. The ring conveying cylinder 53 drives the ring feeding head 52 carrying the buckle ring B to move toward the placement step 22c. Specifically, the ring feeding head 52 includes a stopper 521, a driving plate 522 and a carrier 533, a stopper 521 is movably mounted on the ring conveying cylinder 53, a driving plate 522 is hingedly connected to the stopper 521, and the driving plate 522 has the freedom to swing in the opposite direction of the ring conveying frame 51 on the stopper 521, a reset elastic member 524 is provided between the driving plate 522 and the stopper 521 for providing elastic force for the driving plate 522 to swing in the direction of the ring conveying frame 51, and the carrier 533 is mounted on the driving plate 522 and located between the driving plate 522 and the ring conveying frame 51 for carrying the buckle B;

The deformation pressure head 221 rises and drives the strip A to engage into the recessed guide seat 2352 and the pinching seat 2353, so that the strip A curls, reduces the horizontal width of the strip A, and better enters the edging sleeve C.

[0064] It should be noted that the pinch seat 2353 has a concave cavity and the cavity is elastic. The opening of the cavity is smaller than the width of the deformation head 221 and the depth of the cavity is smaller than the thickness of the deformation head 221, so that the strip A will not get stuck in the pinch seat 2353; and the deformation head 221 is embedded in the cavity of the pinch seat 2353 to cause the pinch seat 2353 to undergo elastic deformation. The cavity edges on both sides of the pinch seat 2353 apply an inclined downward elastic force to the deformation head 221 and the strip A on the deformation head 221, and the vertical component of the elastic force is greater than the lateral component. Therefore, after the deformation head 221 descends and detaches from the strip A, the pinch seat 2353 can drive the strip A to be spread back onto the supporting seat 22.

[0065] Those skilled in the art will appreciate that the width of the edging sleeve C and the width of the strip A are selected based on actual needs. When the edging sleeve C can be directly put on the strip A, in order to ensure the straightness and nesting accuracy of the strip A, the solution of curling and nesting the strip A can be directly adopted.

[0066] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
