[0017] The present invention will be further described in detail below with reference to the accompanying drawings.

[0018] like Figure 1 As shown, a device for punching and locking button holes in clothing includes a support frame 1, a slide 2, a positioning strip 3, a pressing mechanism 4, a punching mechanism 5 and an injection molding locking mechanism 6.

[0019] like Figure 1 、 Figure 2 As shown, the support frame 1 is arranged on the ground in an elongated shape, and the slide 2 is horizontally arranged on the support frame 1 and slidably connected to the support frame 1. The middle position of the slide 2 is penetrated by an operation hole 21. The end position of the slide 2 is vertically slidably connected to the locking rod 22. The support frame 1 is provided with locking holes 11 for inserting the locking rod 22 at intervals.

[0020] like Figure 1 、 Figure 2 As shown, the positioning bar 3 is U-shaped and arranged on the slide 2, and is used to abut the two sides and end positions of the cuff. The pressing mechanism 4 is arranged on the slide 2 and is used to press the cuff. The pressing mechanism 4 includes a pressing frame 41, a crossbeam 42, a sliding rod 43, a cylinder 44 and a pressing block 45.

[0021] like Figure 1 、 Figure 2 As shown, the pressing frame 41 is arranged on the slide 2, the beam 42 is horizontally arranged on the inner wall of the upper end of the pressing frame 41, the sliding rod 43 is vertically slidably connected to the beam 42, the cylinder 44 is used to control the vertical sliding of the sliding rod 43, and the pressure block 45 is arranged at the lower end of the sliding rod 43.

[0022] like Figure 1 、 Figure 2 As shown, the lower end surface of the pressing block 45 is provided with a rubber pad 46 to prevent damage or contamination of the cuff. The two ends of the pressing block 45 are rotatably connected to a rotating frame 47, the rotating position of the rotating frame 47 is provided with a torsion spring 48, and a roller 49 is horizontally arranged between the rotating frames 47.

[0023] like Figure 1 、 Figure 3 As shown, the punching mechanism 5 is arranged in the middle of the support frame 1 and is used to punch holes in the cuffs. The punching mechanism 5 includes a lower punch block 51, an upper punch block 52 and a punching knife 53.

[0024] like Figure 3 As shown, the lower punch 51 and the upper punch 52 are both vertically slidably connected to the support frame 1. The lower punch 51 is used to be embedded in the working hole 21, and the upper punch 52 is used to press the lower punch 51. The punching knife 53 is vertically slidably connected to the middle position of the upper punch 52. The lower punch 51 is provided with a punching groove 54 for the punching knife 53 to be embedded. The side wall of the lower punch 51 is inclined upward to be provided with a chute 55 connected to the punching groove 54.

[0025] like Figure 1 、 Figure 4 As shown, the injection molding and locking mechanism 6 is arranged at the rear end of the support frame 1 and is used to inject rubber around the buttonhole for locking. The injection molding and locking mechanism 6 includes a lower injection molding block 61, an upper injection molding block 62, a connecting block 63 and an injection molding head 64.

[0026] like Figure 4 、 Figure 5 As shown, the lower injection block 61 and the upper injection block 62 are both vertically slidably connected to the support frame 1, the lower injection block 61 is used to be embedded in the working hole 21, and the upper injection block 62 is used to press the lower injection block 61, and the connecting block 63 is arranged in the middle position of the lower injection block 61 and the upper injection block 62, and fits each other after buckling.

[0027] like Figure 4 、 Figure 5 As shown, an annular molding groove 65 is formed between the upper injection molding block 62 and the connecting block 63 thereon, and between the lower injection molding block 61 and the connecting block 63 thereon. An injection head 64 is provided on the lower injection molding block 61 and the upper injection molding block 62. A flow channel 66 connecting the injection head 64 and the molding groove 65 is provided on the lower injection molding block 61 and the upper injection molding block 62. The outlet position of the flow channel 66 is configured in a constricted shape.

[0028] When buttonholes are to be produced on a cuff, the cuff is placed on the slide 2 so that the positioning strips 3 contact the sides and ends of the cuff to achieve preliminary positioning of the cuff. The cylinder 44 then controls the sliding rod 43 to slide downward, which in turn drives the pressing block 45 to move downward synchronously.

[0029] Roller 49 is first to contact the cuff subsequently, and because roller 49 is tilted outwardly, roller 49 can be rotated outwardly, and rotating frame 47 rotates synchronously, utilizing roller 49 to flatten the cuff. Finally, pressing block 45 presses the cuff again to achieve the smooth pressing and fixing of the cuff.

[0030] Then, the slide 2 is controlled to slide backward one station, and the locking rod 22 is inserted into the corresponding locking hole 11, so that the slide 2 is located at the working position of the punching mechanism 5. Then, the lower punch 51 and the upper punch 52 are controlled to move relative to each other, so that the lower punch 51 is inserted into the working hole 21 on the slide 2 and fits the lower end surface of the cuff, while the upper punch 52 presses the cuff against the lower punch 51.

[0031] Then the punching knife 53 is controlled to move downward quickly, and the punching knife 53 is embedded in the punching groove 54 to punch out button holes on the cuffs. At the same time, the punched waste is discharged along the punching groove 54 and the chute 55, realizing automatic discharge of the waste.

[0032] Then the punching knife 53 is controlled to retract, and the lower punch block 51 and the upper punch block 52 are reset, and then the locking rod 22 is pulled out, and then the slide 2 is controlled to continue to slide backward one station, and the locking rod 22 is inserted into the corresponding locking hole 11, so that the slide 2 is located at the injection molding locking mechanism 6 station position.

[0033] Then, the lower injection molding block 61 and the upper injection molding block 62 are controlled to move relative to each other, so that the lower injection molding block 61 is embedded in the working hole 21 on the slide 2 and fits the lower end surface of the cuff. At the same time, the upper injection molding block 62 presses the cuff tightly against the lower injection molding block 61, and the connecting blocks 63 on the lower injection molding block 61 and the upper injection molding block 62 pass through the buttonhole and fit each other. At this time, the molding grooves 65 on the lower injection molding block 61 and the upper injection molding block 62 surround the buttonhole and form an injection cavity.

[0034] The injection head 64 then injects molten rubber into the runner 66, filling the molding groove 65 and wrapping around the buttonhole. After the rubber solidifies, the lower and upper injection blocks 61 and 62 are automatically reset, achieving automatic hemming of the buttonhole. Finally, the excess rod-shaped waste material formed in the runner 66 is sheared off, completing the hemming process.

[0035] Therefore, by setting a sliding connection slide 2, the cuff is fixed on the slide 2, and a continuously operating punching mechanism 5 and an injection molding and locking mechanism 6 are set, the automatic punching and molding of the button holes on the cuff and the rubber injection molding and locking are realized, without the need for sewing, thereby improving production efficiency.

[0036] The specific embodiments are merely explanations of the present invention and are not limitations of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the embodiments as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
