Description

Technical Field

[0001] This utility model relates to the field of garment manufacturing technology, and in particular to a button-opening device that can automatically open multiple button doors. Background Technology

[0002] Buttonholes are typically fabricated at the placket of garments to work with buttons. These buttonholes are categorized into horizontal buttonholes, vertical buttonholes, and buttonholes at other angles. Currently, buttonhole fabrication involves manually holding the garment and placing one area requiring a buttonhole onto the buttonhole machine's processing position for drilling and sewing. After the buttonhole is created, the garment is moved to place another area requiring a buttonhole onto the machine's processing position. When fabricating buttonholes at different angles, the garment must be manually rotated to the appropriate angle.

[0003] However, manual movement and rotation of the garment are not precise enough. This makes it easy for the relative positions and angles of multiple buttons to shift when processing them, and the speed of movement and repositioning is slow, resulting in low processing efficiency. Utility Model Content

[0004] The main purpose of this invention is to propose a button-opening device that can automatically open multiple buttons, aiming to solve the technical problem of low positional accuracy and efficiency of manually moving clothing when processing multiple buttons and buttons at different angles in the prior art.

[0039] like Figures 1 to 12 As shown, a button-opening device capable of automatically opening multiple button doors includes a button-opening machine 1, a drive assembly, and a garment-holding platform 7.

[0040] The button-buttoning machine 1 includes a machine head 11. A cutter and a sewing needle are located on the lower front side of the machine head 11. The cutter is used to cut holes in the garment 9, and the sewing needle is used to sew the edges around the holes. A moving strip 12, linked to the sewing needle, is also located on the lower side of the machine head 11. A presser foot 13 is located at the front end of the moving strip 12. During processing, the presser foot 13 holds the garment 9 in place. The sewing needle is located above the presser foot 13. During sewing, the moving strip 12 can move the presser foot 13 and the garment 9 in the front-back direction within the length of the button. The cutter, sewing needle, moving strip 12, and presser foot 13 are the structure of existing button-buttoning machines 1, and will not be described in detail here.

[0041] The drive assembly includes a fixed component 2, a first movable component 3, and a second movable component 5. The fixed component 2 is fixed relative to the machine head 11. The first movable component 3 is slidably connected to the fixed component 2 in the front-back direction. The first movable component 3 is fixed relative to the moving bar 12 in the front-back direction. The moving bar 12 can drive the first movable component 3 to move back and forth. The first movable component 3 is equipped with a moving drive motor 4. The second movable component 5 is slidably connected to the first movable component 3 in the front-back direction. The second movable component 5 is connected to the moving drive motor 4 in a transmission connection. The moving drive motor 4 can drive the second movable component 5 to move back and forth. The second movable component 5 is equipped with a rotation drive motor 6.

[0042] The garment support platform 7 is used to support and position the garment 9. The garment support platform 7 is rotatably connected to the second moving part 5. The rotation axis of the garment support platform 7 and the second moving part 5 is set in the vertical direction. The garment support platform 7 is connected to the rotation drive motor 6. The rotation drive motor 6 can drive the garment support platform 7 to rotate laterally and move to the underside of the sewing needle and presser foot 13.

[0043] The garment 9, which requires buttonhole opening, can be manually placed and positioned on the garment receiving platform 7. The first moving part 3 and the moving strip 12 of the buttonhole machine 1 are fixed relative to each other in the front-back direction. When opening the buttonhole, the presser foot 13 will press the garment 9 onto the garment receiving platform 7. The moving strip 12 will drive the first moving part 3, the second moving part 5, the garment receiving platform 7, and the garment 9 to move in conjunction with the sewing needle of the buttonhole machine 1, moving the garment 9 within the length range of the buttonhole to sew the edge. The garment receiving platform 7 moves with the sewing edge position of the buttonhole of the garment 9, keeping the garment 9 on the garment receiving platform 7 without shifting.

[0044] The drive motor 4 on the first moving part 3 can drive the second moving part 5, the garment receiving platform 7, and the garment 9 to move in the front-to-back direction, and can move the garment 9 between the positions of multiple buttonholes. The drive motor 6 on the second moving part 5 can drive the garment receiving platform 7 and the garment 9 to rotate, and can rotate the garment 9 to change the opening angle of the buttonholes. Taking opening a horizontal buttonhole 91 located on the upper side and multiple vertical buttonholes 92 located on the lower side as an example, the horizontal buttonhole 91 of the garment 9 can be placed under the cutter and needle of the buttonhole machine 1, referring to... Figure 1 and Figure 3 The horizontal button 91 extends along the front-to-back direction. The button maker 1 opens the horizontal button 91. Then, the garment receiving platform is rotated 7 degrees so that the vertical button 92 is oriented along the front-to-back direction and is positioned directly in front of the cutter and needle of the button maker 1. Then, the second moving part 5 moves the garment receiving platform 7 backward, so that the position of the vertical button 92 is below the cutter and needle of the button maker 1. (Refer to...) Figure 10 Then, the vertical button door 92 is opened, and then the second moving part 5 moves the garment receiving platform 7 to move the next vertical button door 92 to the cutter and sewing needle of the button door machine 1 to open the vertical button door 92.

[0045] When using this button-opening device, simply place the garment 9 on the garment receiving platform 7. The garment receiving platform 7 can then move the garment 9 to the positions of multiple buttons for sequential processing. Furthermore, the garment 9 can be rotated according to the required button angle to achieve button processing at different angles. This allows for the processing of multiple buttons at different angles. Compared to existing methods of manually moving and rotating the garment 9, this button-opening device allows for more precise relative positions and angles of multiple buttons, simplifies manual operation, speeds up the movement of multiple buttons, and improves production efficiency. Additionally, the device utilizes the moving frame on the button-opening machine 1 as a driving force. The linkage between the garment receiving platform 7 and the button-opening machine 1 during processing improves processing accuracy. If the garment receiving platform 7 is not linked to the button-opening machine 1, the relative position of the garment 9 and the garment receiving platform 7 can easily change, affecting the positional accuracy of the multiple buttons.
