DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] As introduced in the background technology, there are deficiencies in the prior art. In order to solve the above technical problems, the present application proposes an automatic edge turning machine and an edge turning method for metal button processing. Embodiment 1

[0040] See also Figure 1 - Fig.10 , an automatic sewing machine, comprising a feeding platform 1 and a sewing platform 3, the feeding platform 1 is arranged on one side of the sewing platform 3, a feeding mechanism 2 is installed on the top of the feeding platform 1, a sewing bin 4 is arranged on the top of the sewing platform 3, a plurality of screening slots 6 are installed inside the sewing bin 4, a hydraulic cylinder mounting rod 7 is installed inside the sewing bin 4, a plurality of telescopic hydraulic rods 8 are installed outside the hydraulic cylinder mounting rod 7, the movable ends of the plurality of telescopic hydraulic rods 8 are all connected with a button fixing mechanism 9, a material receiving tray 10 is installed inside the sewing bin 4, a plurality of sewing turntables 11 are installed inside the sewing bin 4, and a plurality of sewing mechanisms 12 are installed inside the sewing bin 4;

[0041] The feeding mechanism 2 includes a button sorting slot 25, one end of which is connected to the screening slot 6 through a material dividing slot 5, and the feed ends of the plurality of screening slots 6 are fixedly mounted on the same material dividing slot 5;

[0042] The button fixing mechanism 9 is located above the car side turntable 11, and the screening slots 6, the telescopic hydraulic rods 8, the button fixing mechanism 9, the car side turntable 11 and the car side mechanism 12 are equal in number and correspond one to one;

[0043] The feeding mechanism 2 can move the metal buttons from the dividing trough 5 to the screening trough 6. The button sorting trough 25 can screen and separate the incomplete metal buttons when the metal buttons pass by. The screening trough 6 can intercept the metal buttons with large burrs. The telescopic hydraulic rod 8 can drive the button fixing mechanism 9 to move downward. When the button fixing mechanism 9 moves downward, it can drive the metal buttons on the screening trough 6 to move downward and fix the metal buttons on the turning disk 11. The receiving tray 10 can collect the metal buttons on multiple screening troughs 6. The turning disk 11 is used to drive the metal buttons to rotate. The turning mechanism 12 is used to turn the metal buttons.

[0044] During operation, firstly, the stamped metal buttons that need to be sewn are poured into the feeding mechanism 2, which can drive the metal buttons to be arranged and rise in order. During the rising process of the metal buttons, the button sorting slot 25 can screen and separate the defective ones in the metal buttons, and the complete metal buttons enter the screening slot 6 from the sorting slot 5 respectively. The screening slot 6 can intercept the metal buttons that have not been sewn. After the interception, the telescopic hydraulic rod 8 drives the button fixing mechanism 9 to move downward.

After the trimming is completed, the button fixing mechanism 9 drives the metal to move upward, and when the metal button moves above the screening slot 6, the button fixing mechanism 9 releases the fixation of the metal button. After trimming, the metal button returns to the inside of the screening slot 6 again, and then enters the receiving tray 10 through the screening slot 6. After being collected by the receiving tray 10, they are uniformly discharged from the inside of the discharge port 13. When the metal buttons are arranged and moved, the defective metal buttons can be screened through the button sorting slot 25 to prevent the defective metal buttons from being fixed on the trimming turntable at the same time as the normal metal buttons during the subsequent trimming, causing damage to the normal metal buttons and the trimming tools. Embodiment 2

[0045] The difference from the above embodiment is that, please refer to Figure 2 - Figure 5 The feeding mechanism 2 includes a button feeding turntable 21, which is rotatably mounted on the top of the feeding platform 1. A button limiting protrusion 22 is provided on the top of the button feeding turntable 21. A storage sleeve 23 is fixedly mounted on the top of the feeding platform 1. A feeding spiral groove 24 is fixedly mounted inside the storage sleeve 23. The top of the feeding spiral groove 24 passes through the side wall of the storage sleeve 23 and is connected to a button sorting groove 25. The button sorting groove 25 is fixedly mounted on the outside of the storage sleeve 23. A feeding funnel 26 is installed on the top of the button sorting groove 25.

[0046] The button limiting protrusion 22 is installed at the center of the top of the button feeding turntable 21. The top of the button limiting protrusion 22 is provided with an upward protrusion. The bottom of the feeding spiral groove 24 fits with the concave part of the edge of the button feeding turntable 21. The storage sleeve 23 is located outside the button feeding turntable 21.

[0047] The loading platform 1 can drive the button loading turntable 21 and the button limiting protrusion 22 to rotate inside the storage sleeve 23. The rotation direction of the button loading turntable 21 is the same as the spiral direction of the loading spiral groove 24. The button limiting protrusion 22 can make the metal buttons move toward the edge of the button limiting protrusion 22 when the button loading turntable 21 rotates. When the button loading turntable 21 rotates, the metal buttons at the edge of the button loading turntable 21 can move upward in a spiral along the loading spiral groove 24.

[0048] The button sorting slot 25 comprises a sorting slot body 251, wherein a complete button slot 252 is respectively provided inside the sorting slot body 251, and an incomplete button slot 253 is provided inside the sorting slot body 251. A sorting limit block 254 is arranged inside the sorting slot body 251, and a button diversion port 255 is provided on the side wall between the complete button slot 252 and the incomplete button slot 253.

[0049] One end of the complete button groove 252 is connected to the feeding spiral groove 24, and the other end of the complete button groove 252 is connected to the dividing groove 5. Both ends of the sorting limit block 254 are inclined structures. The sorting limit block 254 can make the buttons passing through the complete button groove 252 stand up first and then lay flat.

[0050] During operation, the metal buttons to be processed are first poured into the storage sleeve 23 through the feeding funnel 26, and the feeding platform 1 can drive the button feeding turntable 21 and the button limiting protrusion 22 to rotate inside the storage sleeve 23. When the button feeding turntable 21 rotates, the metal buttons on the edge of the button feeding turntable 21 can be driven to move upward along the feeding spiral groove 24, and when the button feeding turntable 21 rotates, the button limiting protrusion 22 can also be driven to rotate synchronously. When the button limiting protrusion 22 rotates, The metal button can be moved toward the edge of the button feeding turntable 21. After the metal button passes through the feeding spiral groove 24, it enters the complete button groove 252. When the metal button moves along the complete button groove 252, one side of the metal button can be tilted along the inclined surface on the sorting limit block 254, and the metal button is erected as a whole during the gradual movement. After the metal button is erected, it rolls inside the complete button groove 252. During the movement of the metal button, the metal button will move toward one side of the complete button groove 252. Tilt, when the complete button is tilted, the button will contact the upper part of the complete button groove 252, so that the button can continue to move along the complete button groove 252, and the notch on the edge of the metal button with a broken edge can contact the inside of the complete button groove 252 when moving, so that the broken metal button cannot roll and move, and the broken metal button that slides is more likely to tilt during the movement, and when the notch on the broken metal button contacts the complete button groove 252, it will cause the height of the top of the broken metal button to be lower than the height of the complete metal button. When the edge position of the metal button is broken and causes its height loss to a certain extent (generally 3% of the height of the complete metal button when standing upright), the broken metal button will slide from the button diversion port 255 into the inside of the broken button groove 253 when tilted, while the complete metal button will enter the inside of the dividing trough 5 through the complete button groove 252. The metal buttons are erected for screening during the movement of the metal buttons, which can effectively prevent the broken metal buttons from entering the next process. Embodiment 3

[0051] The difference from the above embodiment is that, please refer to Figure 1 - Fig.10 The screening trough 6 includes a screening feed section 61, which is fixedly installed on the outside of the distribution trough 5. A button hole 62 is opened inside the screening feed section 61. An elastic connecting rod 65 is installed outside the screening feed section 61. The other end of the elastic connecting rod 65 is connected to a screening discharge section 63. A screening card slot 64 is opened inside the screening discharge section 63.

[0052] The screening material discharging section 63 is movably connected to the screening material feeding section 61 through an elastic connecting rod 65. When the distance between the screening material feeding section 61 and the screening material discharging section 63 changes, the size of the button perforation 62 can be adjusted. The button fixing mechanism 9 can drive the metal buttons to pass through the button perforation 62 and fix the metal buttons on the car side turntable 11. The screening card slot 64 on the screening material discharging section 63 can intercept the metal buttons that have not been carved, and the metal buttons that have passed the car side can fall onto the receiving tray 10 through the screening material discharging section 63.

[0053] The button fixing mechanism 9 includes a transmission rotating rod 91, which is rotatably connected to the piston end of the telescopic hydraulic rod 8. Two telescopic connecting blocks 92 are fixedly installed on the outside of the transmission rotating rod 91. The movable ends of the two telescopic connecting blocks 92 are connected to a clamping sleeve 93. A sleeve slide groove 94 is opened inside the clamping sleeve 93. A sleeve connecting rod 95 is slidably installed inside the sleeve slide groove 94. A connecting rod fixing ring 96 is installed on the top of the sleeve connecting rod 95. A protective sleeve 97 is rotatably installed on the top of the connecting rod fixing ring 96. A sleeve spring 98 is installed on the top of the protective sleeve 97.

[0054] The sleeve slide grooves 94 on both sides of the clamping sleeve 93 are inclined structures. The two clamping sleeves 93 are movably connected by a sleeve connecting rod 95. The two clamping sleeves 93 can move in the horizontal direction through the telescopic connecting block 92. When the clamping sleeve 93 moves horizontally, the position of the metal button can be fixed;

[0055] When the telescopic hydraulic rod 8 is extended or retracted, it can drive the transmission rotating rod 91 to move up and down. When the transmission rotating rod 91 moves up and down, it can drive the clamping sleeve 93 to move up and down through the telescopic connecting block 92. The clamping sleeve 93 moves up and down to drive the metal button to pass through the screening slot 6.

[0056] The two sleeve connecting rods 95 between the clamping sleeves 93 are rotatably connected to the inside of the protective sleeve 97 through a connecting rod fixing ring 96, and the top of the protective sleeve 97 is connected to the fixed end of the telescopic hydraulic rod 8 through a sleeve spring 98;

[0057] When the clamping sleeve 93 moves downward, the two clamping sleeves 93 can be driven to move toward the center of the transmission rotating rod 91 through the sleeve connecting rod 95. When the clamping sleeve 93 moves downward, the protective sleeve 97 can be driven to move downward through the sleeve connecting rod 95 and the connecting rod fixing ring 96.

[0058] The metal buttons are diverted to different screening slots 6 through the dividing trough 5, and the metal buttons that have not been machined will be intercepted at the connection between the screening feed section 61 and the screening discharge section 63 by the screening card slot 64. At this time, the movable end of the telescopic hydraulic rod 8 extends to drive the transmission rotating rod 91 to move downward. When the transmission rotating rod 91 moves downward, it can drive the clamping sleeve 93 to move downward synchronously through the telescopic connecting block 92. When the clamping sleeve 93 moves downward, the sleeve connecting rod 95 slides upward relatively inside the sleeve slide groove 94. When the position of the sleeve connecting rod 95 inside the sleeve slide groove 94 rises, it can drive the clamping sleeve 93 to move closer to the center of the transmission rotating rod 91. During the descent of the metal button 91, the metal button can be inserted into the hole in the middle of the metal button to fix the position of the metal button. When the clamping sleeve 93 approaches the center of the transmission rotating rod 91, the protrusion on the metal button can be clamped. When the transmission rotating rod 91 continues to descend, the metal button can be driven to move downward. At this time, the clamping sleeve 93 continues to move downward and can drive the protective sleeve 97 to move downward from the initial position through the sleeve connecting rod 95. When the protective sleeve 97 moves downward, the sleeve spring 98 can be extended. When the metal button moves, it can drive the screening discharge section 63 to move away from the screening feed section 61 through extrusion to expand the button perforation 62, so that the metal button can be moved from the button perforation. When the car side turntable 11 drives the metal button to rotate, the transmission rod 91 and the clamping sleeve 93 can be driven to rotate synchronously. After the car side turntable 11 is completed, the movable end of the telescopic hydraulic rod 8 is shortened to drive the transmission rod 91 to move upward. When the transmission rod 91 drives the clamping sleeve 93 to move upward, the sleeve spring 98 is first contracted. When the clamping sleeve 93 drives the metal button to move above the screening slot 6, the protective sleeve 97 returns to the initial position. At this time, the screening discharge section 63 is driven by the elastic connecting rod 65 to move toward the direction close to the screening feed section 61 so that the button When the button perforation 62 shrinks and the clamping sleeve 93 continues to rise, the sleeve connecting rod 95 can slide downward inside the sleeve slide groove 94. When the sleeve connecting rod 95 slides downward inside the sleeve slide groove 94, it can drive the clamping sleeve 93 to separate and release the metal button in the direction away from the transmission rotating rod 91, and the metal button falls back to the connection between the screening feed section 61 and the screening discharge section 63, and the metal button after turning can pass through the screening slot 64 and enter the receiving tray 10. During the turning process, the button fixing mechanism 9 can automatically complete the fixing and movement of the metal button when the telescopic hydraulic rod 8 is extended and retracted, which can effectively prevent the turning error of the metal button caused by the fixing accuracy.
