Description

Technical Field

[0001] This utility model belongs to the field of keyhole machine technology, specifically relating to a safe keyhole machine that is easy to adjust. Background Technology

[0002] Buttonhole machines (also known as buttonhole sewing machines) are specialized garment machinery primarily used for sewing buttonholes in clothing. They are divided into two categories: flat-head buttonhole machines (straight buttonhole machines) and round-head buttonhole machines (phoenix buttonhole machines). Round-head buttonhole machines are mostly used for processing medium-thick fabrics, producing buttonholes with rounded front ends and uniform stitches. Flat-head buttonhole machines are widely used for buttonhole applications in industrial-grade fabrics. This equipment consists of nine main mechanisms, including feeding, hooks, and needle bars. It employs double-curved needles and double-forked needles to create a composite chain stitch, and the elastic presser foot can adapt to different fabric thicknesses. The buttonhole shape is adjusted by changing cams, and it is equipped with an automatic thread cutting device. Domestically produced equipment incorporates electronic technology and mechatronics design, developing fully automatic computer-controlled models that significantly improve sewing accuracy and stability. Mainstream models such as Zhongfeng Heavy Industry CBH-1790 and Jack JK-T781D support high-speed sewing (up to 4200rpm) and are suitable for processing materials from thin to medium-thick materials. In actual buttonhole machine operation, many buttonhole machines require manual adjustment of the fabric position, which is not convenient to adjust to the precise position. Moreover, manual adjustment is prone to needle pricks and cutter pinches, which greatly increases the risk of injury during operation. Therefore, a safe buttonhole machine that is easy to adjust is designed. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-3 This utility model provides the following technical solution: an easily adjustable safety keyhole machine, including a workbench 1, a base 2 mounted on the upper side of the workbench 1, a first motor 3 mounted on the upper side of the base 2, a first rotating shaft mounted on the output end of the first motor 3, a first threaded rod 9 mounted on the surface of the first rotating shaft, a first gear 6 mounted on one side of the surface of the first rotating shaft, a second gear 7 meshing with one side of the first gear 6, a third gear 8 meshing with the other side of the second gear 7, a second rotating shaft mounted on the surface of the third gear 8, a second threaded rod 10 mounted on the surface of the second rotating shaft, a support block 23 mounted on the upper side of the workbench 1, a keyhole machine 24 mounted on the upper side of the support block 23, a first sliding block 11 threadedly mounted on one side of the surface of the first threaded rod 9, a first electric push rod 13 mounted on one side of the first sliding block 11, a first connecting block 14 mounted on the other side of the first electric push rod 13, and the first connecting block... A second motor 16 is installed on the upper side of 14. A fourth rotating shaft is installed at the output end of the second motor 16. A first top plate 22 is installed on the other side of the fourth rotating shaft. A third threaded rod 17 is installed on the surface of the fourth rotating shaft. A third sliding block 18 is installed on the surface of the third threaded rod 17. A first pressure plate 19 is installed on one side of the third sliding block 18. A fourth sliding block 20 is installed on the other side of the first pressure plate 19. A sliding rod 21 is installed on the inner side of the fourth sliding block 20. A second sliding block 12 is threaded on the surface of the second threaded rod 10. A fourth electric push rod 28 is installed on one side of the second sliding block 12. A second connecting block 29 is installed on the other side of the fourth electric push rod 28. A second support column 31 is installed on the upper side of the second connecting block 29. A second top plate 32 is installed on the upper side of the second support column 31. A second electric push rod 33 is installed on the lower side of the second top plate 32. A second pressure plate 34 is installed on the lower side of the second electric push rod 33.

[0020] In this embodiment, by setting the third threaded rod 17, the third sliding block 18, the first pressure plate 19, the fourth sliding block 20 and the slide rod 21, the fabric can be effectively clamped and fixed.

[0021] In this embodiment, by setting the first threaded rod 9 and the second threaded rod 10, the device can drive the fabric to move back and forth, which increases the flexibility of the device and saves labor costs.

[0022] In this embodiment, by setting up a support plate 35, a third electric push rod 36, and a transparent protective plate 26, the transparent protective plate 26 can be lowered by adjusting the third electric push rod 36 when the buttonhole machine is working, thereby reducing the risk of workers being pricked by needles and pinched by cutters, effectively protecting workers. By setting up a transparent plate, the working situation can be observed.

[0023] The working principle and usage process of this utility model are as follows: After the utility model is installed, the front end of the fabric is passed sequentially from above the upper feed roller 27 of the second rubber plate 30 and above the upper part of the first rubber plate 15. After aligning with the position to be buttonholed, the second motor 16 is turned on, which rotates the third threaded rod 17 to lower the height of the third sliding block 18, thereby causing the first pressure plate 19 to move downward until the fabric is clamped. Then, the second motor 16 is turned off, and the second electric push rod 33 is turned on, causing it to slowly lower until the second pressure plate 34 clamps the fabric. Then, the second electric push rod 33 is turned off, and the third electric push rod 36 is turned on, causing the transparent protective plate 26 to lower until it is on the surface of the fabric. Then, the transparent protective plate 26 is turned off, which prevents workers from being pricked by needles or pinched by cutters, effectively improving the safety of the device. The buttonhole machine 24 is then turned on to start the buttonhole machine. When the work is completed... Afterwards, the first electric push rod 13 or the second electric push rod 28 can be activated to move the fabric left and right. When the desired position is reached, the first electric push rod 13 or the second electric push rod 28 can be deactivated, and the buttonhole machine 24 can be restarted for operation. After the work is completed, if it is necessary to work on the front or back of the fabric, the first gear 6 can be activated to flexibly drive the first threaded rod 9 and the second threaded rod 10 to move back and forth synchronously, thereby moving the fabric back and forth, greatly improving the flexibility of the device. When the work is finished, the second electric push rod 33 and the second motor 16 can be opened to release the clamp on the fabric, and the finished fabric can be taken out. All electrical equipment in this device is powered by an external power supply, and all motors and electric push rods in this device are connected and controlled by a PLC control system.
