[0027] See also Figure 1-5 A buttonhole buttoning device includes a fixing mechanism 1, which includes a bottom plate 101. The top of the bottom plate 101 is fixedly connected to a sewing machine body 102. The setting of the sewing machine body 102 can be used to lock the edge of the fabric and sew the button to the fabric. A turntable 103 is provided between the sewing machine body 102 and the bottom plate 101. The edge of the turntable 103 is provided with a plurality of avoidance openings 104 in a circular array.

The outer side of each group of arc-shaped guide rods 105 is symmetrically fixedly connected with a retaining ring 108, and a first spring 109 is fixedly connected between the retaining ring 108 and the clamping plate 107. Specifically, the first spring 109 is in a compressed state, so that the elastic action of the first spring 109 can push the clamping plates 107 on both sides to move relative to each other, so as to meet the clamping and fixing of the button.

[0029] The opposite sides of two adjacent clamping plates 107 are provided with avoidance grooves 106, and the retaining ring 108 is adapted to the avoidance grooves 106. The avoidance grooves 106 are provided to avoid the retaining ring 108 when the clamping plates 107 move. The feeding mechanism 2 includes a guide wheel 214 rotatably connected to the top of the arc-shaped carriage 113, and a driving mechanism 3. The driving mechanism 3 includes a guide column 303 that penetrates and is fixed inside the guide wheel 214. The setting of the guide column 303 can provide support and fixation for the guide wheel 214. The outer side of the guide column 303 is rotatably connected with a tooth column 305. The top of the tooth column 305 is fixedly connected to the turntable 103 and penetrates the bottom plate 101.

[0030] The bottom of the guide column 303 is fixedly connected with a traction plate 309, and a hydraulic rod 310 is symmetrically fixedly connected between the traction plate 309 and the bottom plate 101. The setting of the hydraulic rod 310 can drive the traction plate 309, the guide column 303 and the gear column 305 to move up and down when starting work, thereby driving the turntable 103 to press the fabric to a limit position. The bottom four corners of the bottom of the bottom plate 101 are fixedly connected with a bottom rod 301, and the bottom of the bottom rod 301 is fixedly connected with a fixed plate 302.

The output end of the stepper motor 308 is fixedly connected to the drive shaft 307. The stepper motor 308 is set to drive the drive shaft 307 and the gear 306 to rotate when starting the work. When the gear 306 rotates, it can drive the gear column 305 and the turntable 103 to rotate accordingly. A plurality of guide blocks 208 are fixed in an annular array on the top of the turntable 103. The inside of each group of guide blocks 208 is slidably penetrated by a push rod 204. The setting of the guide block 208 is used to guide the movement of the push rod 204.

[0032] A push head 206 corresponding to two adjacent clamping plates 107 is fixedly connected to one side of each push rod 204 near the clamping plate 107. When the push head 206 moves between the two clamping plates 107, it can push the two clamping plates 107 to move away from each other along the outer side of the arc-shaped guide rod 105, so that the two clamping plates 107 can be unfolded to facilitate the button to be placed in the clamping groove 110. A second spring 205 is fixedly connected between the push head 206 and the guide block 208, so that the push head 206 can be pulled out from between the two clamping plates 107 by the elastic action of the second spring 205. A protrusion 215 is fixedly connected to one side of the outer wall of the guide wheel 214, and when the push rod 204 moves onto the protrusion 215, it can push the push rod 204 to move to the side away from the push rod 204.

[0033] A ball bearing 209 is provided on one side of each push rod 204 away from the push head 206, and each ball bearing 209 contacts the outer side of the guide wheel 214. The provision of the ball bearing 209 can reduce the wear between the push rod 204 and the guide wheel 214. An extension plate 201 is fixedly connected to one side of the sewing machine body 102, and a buckle tube 202 is fixedly passed through the extension plate 201. The buckle tube 202 corresponds to the arc-shaped drag plate 113 and the protrusion 215. The buckle tube 202 is provided to accommodate and limit the buttons so that the buttons can be stacked inside the buckle tube 202. An observation port 203 is provided on one side wall of the buckle tube 202, and the provision of the observation port 203 can be used to observe the remaining amount of buttons inside the buckle tube 202. A plurality of arc-shaped slide plates 113 are fixedly connected to the top of the turntable 103 in a circular array, and each group of clamping plates 107 is slidably connected to the arc-shaped slide plates 113 . The arrangement of the arc-shaped slide plates 113 can support the buttons inside the buckle tube 202 .

[0034] The outer side of each group of push rods 204 is fixedly connected with a material-shifting ring 207, and the top of the push rod 204 is fixedly connected with a shielding plate 210. A toggle block 211 is slidably penetrated on one side of the shielding plate 210. When the toggle block 211 moves to one side of the top push head 206, the material-shifting ring 207, the push rod 204 and the top push head 206 can be pushed to move between the two clamping plates 107, so that the button and the fabric sewing nail button can remove the button. A guide rod 212 is slidably penetrated inside the toggle block 211, and the guide rod 212 is fixedly connected with the shielding plate 210. A third spring 213 is sleeved on the outer side of the guide rod 212. The two ends of the third spring 213 are respectively fixedly connected with the toggle block 211 and the shielding plate 210. The setting of the third spring 213 can use its own elasticity to push the toggle block 211 to reset.

[0035] In this embodiment, the sewing machine body 102 is prior art and will not be described in detail herein.

[0036] During use, when it is necessary to buttonhole the fabric, the fabric is placed on the top of the bottom plate 101, and then the sewing machine body 102 is started to buttonhole the fabric. When buttons need to be nailed on the fabric, the buttons to be nailed can be stacked in this way inside the button tube 202 that matches it, and then the stepper motor 308 is started, so that the stepper motor 308 can drive the gear column 305 and the turntable 103 to rotate through the transmission of the drive shaft 307 and the gear 306 when starting work. When the turntable 103 rotates, it can drive each group of push rods 204 to rotate accordingly, so that each group of balls 209 rolls along the outer wall of the guide wheel 214. When the balls 209 roll to the protrusion 215, they can push the corresponding push rod 204 and the push head 206 to move between the corresponding two clamping plates 107, and at the same time the corresponding second spring 205 is compressed and deformed. The push head 206 pushes the corresponding two clamping plates 107 open, so that the corresponding two clamping plates 107 move in opposite directions, and then the button on the lower side of the buckle tube 202 falls into the corresponding two clamping grooves 110 under the action of gravity, and the corresponding two lower limit plates 111 provide support for the button falling into the clamping groove 110. When the ball 209 rolls away from the protrusion 215, the corresponding second spring 205 restores its deformation, thereby pulling the corresponding push head 206 to withdraw from between the corresponding two clamping plates 107, and then the corresponding two first springs 109 restore their deformation, thereby driving the two clamping plates 107 to move relative to each other, thereby clamping the button inside the lower limit plate 111, and at the same time, the upper limit plates 112 on both sides can limit the top of the button, thereby completing the loading of a button, and then the subsequent button loading is carried out in sequence;

[0037] The clamped button can rotate with the rotation of the arc-shaped drag plate 113. When the button is transported to the bottom of the sewing end of the sewing machine body 102, the position of the fabric with the button can be placed under the button, and then the hydraulic rods 310 on both sides are started, so that the hydraulic rods 310 can drive the traction plate 309, the guide column 303 and the turntable 103 to move downward when starting the work, until the turntable 103 presses the fabric to the limit position, and then the sewing machine body 102 can be started to sew the button on the fabric. After the button is sewn, the toggle block 211 is moved toward the side close to the push head 206, thereby pushing the corresponding material shifting ring 207 to move toward one side of the push head 206, so that the push head 206 pushes the corresponding two sets of clamping plates 107 to move away from each other, thereby stopping the clamping of the button that has been sewn, and then the button and the fabric can be removed.

[0038] The above embodiments are preferred implementation modes of the present invention and are only used to facilitate the explanation of the present invention. They are not intended to limit the present invention in any form. Any person with ordinary knowledge in the relevant technical field, if they do not depart from the scope of the technical features of the present invention, can make equivalent embodiments by partial changes or modifications to the technical contents disclosed in the present invention, and they still fall within the scope of the technical features of the present invention without departing from the technical features of the present invention.
