[0032] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0033] Refer to Figures 1-6, an embodiment provided by the present utility model: a round hole lockstitch machine, including a lockstitch machine main body 1, a wire inlet hole 2 is penetrated through the front part of the upper end of the lockstitch machine main body 1. When the wire is wound around other winding posts and then blown into the wire inlet hole 2 by an air gun, a hole locking device 3 is arranged at the front part of the inner side of the upper end of the lockstitch machine main body 1, and a pressing device 4 is arranged at the rear part of the inner side of the upper end of the lockstitch machine main body 1 near the hole locking device 3. After receiving an instruction, the pressing device 4 will move downward to press the fabric. Subsequently, the hole locking device 3 moves downward to perform the hole locking work. After the hole locking processing at one position is completed, the hole locking device 3 and the pressing device 4 will move back to their original positions to facilitate adjusting the position of the fabric. A plurality of numerical control rods 6 are penetrated through the upper part of the front end of the base of the lockstitch machine main body 1, and a workbench 5 is fixedly arranged at the front ends of the plurality of numerical control rods 6. The plurality of numerical control rods 6 can accurately move the workbench 5 through numerical control in cooperation with the hole locking device 3;
[0034] Plate grooves 17 are respectively opened at both sides of the upper end of the workbench 5. The two plate grooves 17 can just place the unfolded main board 7 and secondary board 9. Second rotating rods 20 are rotatably arranged at the inner sides of the two plate grooves 17. The main boards 7 are fixedly sleeved around the circumferences of the two second rotating rods 20. The main boards 7 can rotate around the circumferences of the second rotating rods 20 and have a certain arc shape, and will not have contact conflicts with adjacent surfaces during the rotation process. Sliding grooves 21 are respectively opened at the front and rear parts of the upper end of one of the two main boards 7. Protrusions 11 are slidably arranged in the two sliding grooves 21. The circumferential dimension of the lower part of the protrusion 11 fits the internal dimension of the sliding groove 21, and the bottom of the protrusion 11 is clamped in the bottom groove of the sliding groove 21, so that the protrusion 11 is not easy to fall off and can slide better. An activity rod 12 penetrates between the two protrusions 11. A slider 13 is slidably sleeved around the circumference of the activity rod 12. The slider 13 can slide back and forth on the activity rod 12. A pressing block 16 is slidably arranged in the groove at the other side of the slider 13. One end of the fabric is fixed through the pressing block 16, which can more conveniently control the position adjustment of the fabric. First rotating rods 15 are rotatably arranged at the front and rear ends of the two main boards 7. The secondary boards 9 are fixedly sleeved around the circumferences of the plurality of first rotating rods 15. The secondary boards 9 can rotate on the first rotating rods 15, and the contact part has a certain arc shape. The secondary boards 9 will not have contact conflicts with adjacent surfaces during the rotation;
[0035] In order to more conveniently and precisely adjust the position of the fabric while saving costs, ensure that the spacing of the buttonholes processed on the fabric is approximately consistent, and improve the aesthetics, a scale 14 is fixedly arranged at the rear of the upper end of one of the two main boards 7. A plurality of buckle grooves 8 are formed on both sides of the upper end of the workbench 5. The secondary board 9 and the main board 7 can be lifted from the buckle grooves 8. Rotating blocks 19 are rotatably arranged on the outer sides of the secondary boards 9 on one side among the plurality of secondary boards 9, and fixed blocks 18 are fixedly arranged on the outer sides of the secondary boards 9 on the other side among the plurality of secondary boards 9. When the two secondary boards 9 are in contact, a more stable connection is achieved by rotating the rotating block 19 to the upper groove of the fixed block 18. A thread cutting opening 10 is fixedly arranged in the groove near the center of the upper end of the workbench 5, and the redundant thread after buttonhole processing can be seen;
[0036] When the device is not in use, the plurality of secondary boards 9 can be buckled up from the corresponding buckle grooves 8. During the buckling process, the plurality of secondary boards 9 will rotate on the corresponding first rotating rods 15, and the rotation process will not conflict with the main board 7 and the workbench 5. The two main boards 7 can be rotated on the second rotating rods 20 to a position perpendicular to the horizontal plane of the workbench 5. After adjusting the positions of the plurality of secondary boards 9, the two secondary boards 9 on both sides are combined, and then the rotating block 19 is rotated to the upper groove of the fixed block 18 to fix it, forming a closed space for dust prevention. When the device is in use, one end of the fabric to be processed is pressed and fixed by the pressing block 16. When performing buttonhole work, the front and rear positions can be adjusted by sliding the slider 13 on the movable rod 12, the positions on both sides can be adjusted by sliding the convex block 11 on the sliding groove 21, and precise position adjustment can be performed through the scale 14, making the position adjustment more effective on the premise of reducing costs;
[0037] Multiple secondary boards 9 and two main boards 7 can be exactly placed in the board slot 17. The secondary boards 9 and the main boards 7 can be lifted through the buckle slots 8, so that the workbench 5 is as flat as possible during work, without redundant protrusions affecting the buttonholing processing of the fabric. The dimensions of the lower parts around the bodies of multiple bumps 11 are all fitted with the inside of the sliding slots 21, and the bottoms of the multiple bumps 11 are all clamped and arranged in the bottom grooves of the sliding slots 21. The multiple bumps 11 can slide better along the sliding slots 21 and will not fall off after the main board 7 is lifted. Magnetic sealing materials are arranged at the joint connections between the two main boards 7 and the multiple secondary boards 9, so that the gaps at the joints are magnetically sealed, making it difficult for dust to penetrate through the gaps. The connections between the two main boards 7 and the second rotating rod 20 have a certain curvature, and the connections between the multiple secondary boards 9 and the first rotating rod 15 have a certain curvature, so that the main board 7 and the secondary boards 9 will not have contact conflicts with adjacent surfaces such as the workbench 5 when rotating. Both of the two rotating blocks 19 can be rotated to the upper groove of the fixed block 18 through rotation, which can make the two secondary boards 9 on both sides be better connected together after adjusting the positions and are convenient to open. The two main boards 7 can just form a closed space with the upper and lower devices by rotating on the second rotating rod 20. When the buttonholing machine is not in use, it can better protect the buttonholing device 3 and the thread cutting opening 10 from dust.
[0038] Working principle: When using this device, one end of the fabric can be fixed and pressed through the pressing block 16, so that the slider 13 slides on the movable rod 12 to adjust the front and back positions of the fabric. After processing a buttonhole under the cooperation of the buttonholing device 3 and the pressing device 4, by observing the scale 14, the bump 11 is moved to slide on the sliding slot 21, and the processing position of the fabric required is adjusted more precisely and controllably. After using this device, the main board 7 and the secondary boards 9 are lifted through the buckle slots 8, so that the main board 7 rotates to a position perpendicular to the surface of the workbench 5. The positions of the two secondary boards 9 on both sides are rotated and adjusted so that the two secondary boards 9 on both sides are combined. The rotating block 19 is rotated to the upper groove of the fixed block 18 so that the two secondary boards 9 on both sides are stably connected. At this time, a closed space is formed, and the magnetic attraction settings at the overlapping parts of the main board 7 and the secondary boards 9 with the adjacent surfaces make it more difficult for dust to enter through the gaps.
[0039] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
