[0028] Specific application examples of this utility model:

[0029] By arranging a magic buckle feeding device on the side of the sewing machine assembly away from the drawstring assembly, the magic buckle is cut by the rounded corner cutting assembly arranged in the magic buckle feeding device. After the cutting is completed, the magic buckle is pushed into the sewing machine assembly by the magic buckle feeding device, thereby completing the assembly of the magic buckle and the umbrella strap, so that when the magic buckle machine is assembled on the magic buckle and the umbrella strap, there is no need to process the magic buckle separately before assembling.

[0030] The Velcro feeding assembly uses the first drive motor to drive the feeding wheel through a preset value to push the Velcro onto the feeding guide rail, thereby loading the Velcro raw material, and multiple groups of feeding wheels are arranged in sequence along the feeding guide rail, which can alternately feed the Velcro, which is conducive to shortening the Velcro feeding interval.

[0031] The number of feeding wheels can be set to two groups, and the two groups of feeding wheels respectively feed the magic buckle female buckle and the male buckle, and the two groups of feeding wheels rotate alternately, so that the magic buckle female buckle and the male buckle are fed in groups alternately.

[0032] The pressing plate is pushed by a double-rod cylinder to move the pressing plate parallely downward, and the feeding guide rail cooperates with the pressing plate to clamp the magic buckle to fix it.

[0033] The rounded corner cutter motor starts up and drives the rounded corner upper cutter die to press down and cut the magic buckle, thereby cutting and shaping the magic buckle.

[0034] After the umbrella strap and the magic buckle are moved to the bottom plate of the sewing machine, the sewing machine presser foot is moved down so that the sewing machine presser foot and the sewing machine bottom plate cooperate with each other and clamp the umbrella strap and the magic buckle at the same time, making it convenient for the sewing machine to sew and assemble the umbrella strap and the magic buckle.

[0035] The drawstring clamp cylinder drives the drawstring clamp to move downward to clamp and fix the end of the umbrella strap close to the sewing machine. The drawstring clamp is arranged on the drawstring clamp slider.

[0036] Control and equipment parameter modification are controlled through the human-machine interaction screen and the start, stop, power, and reset buttons on the panel. When loading the umbrella strap, the feeding wheel rotates counterclockwise, allowing the umbrella strap to enter the umbrella strap detection sensor to detect the presence of umbrella straps or defective umbrella straps. The umbrella straps then enter the tension detection sensor to detect the tensile strength. If the material is stuck, the system will automatically alarm and shut down. The umbrella straps passing through multiple sets of sensors in sequence enter the feed end of the drawstring assembly, which helps to ensure that the umbrella straps entering the drawstring assembly are good.

[0037] The unloading clamp clamps the sewing end of the umbrella strap and the magic buckle through the unloading cylinder. After the sewing machine is completed, the unloading cylinder drives the unloading clamp to move the umbrella strap to the unloading hopper for leveling. The unloading hopper pushes the hopper door open through the cylinder, and the umbrella strap slides into the conveyor belt below and is transported to the production of the next umbrella strap.
