Description

Technical Field

[0001] The utility model belongs to the technical field of clip embedding machines and relates to a locking type clip embedding machine. Background Art

[0002] A sewing machine is a device used in garment processing, primarily for sewing thick fabrics such as shirts, windbreakers, jeans, raincoats, and filter bags. For example, a Chinese patent document discloses a wide-stitch sewing machine (application number: 200920002445.8), comprising a looper assembly, a looper seat, a looper seat shaft, a needle plate, a needle clamp, and a main structure of the sewing machine. The looper assembly is mounted on the looper seat, the looper seat is connected to the looper seat shaft, the looper seat shaft is mounted in the main structure of the sewing machine, the needle plate cooperates with the needle clamp and is mounted on the main structure of the sewing machine. The looper seat is an integral structure, and the loopers in the looper assembly are respectively mounted and fixed in the needle grooves of the looper seat. The looper assembly consists of three loopers with different hook lengths. The loopers are arranged in descending order in the needle grooves of the looper seat according to their hook lengths. After installation, the distance between the longest and shortest loopers is 12.7 mm.

[0003] Although the wide stitch embedding machine can be used to process and sew wide stitch products, it can only form chain stitches like traditional embedding machines. When the chain line breaks, the edge lock is likely to come loose, that is, the connection between the stitch and the fabric is poor and is prone to loosening or falling off. Summary of the Invention

[0004] The purpose of the present invention is to solve the above problems in the existing technology and propose a locking clip embedding machine. The technical problem to be solved by the present invention is how to improve the tightness of the connection between the sewing stitches and the fabric to prevent them from loosening or falling off.

[0005] The purpose of this utility model can be achieved through the following technical solutions:

[0006] A locking clamp embedding machine includes a machine head and a machine base, a needle bar is provided on the machine head, and a lower main shaft that can rotate relative to the machine base is provided on the machine base. It is characterized in that the machine base is also provided with a mounting seat and a mounting shaft that can rotate relative to the machine base, the mounting shaft is arranged parallel to the lower main shaft and the two are connected by a synchronous belt assembly, a worm gear is provided on the mounting shaft, and a worm assembly that meshes with the worm gear is rotatably provided on the mounting seat, and a horizontally arranged rotary hook is connected to the worm assembly, and the rotary hook is located below the needle bar.

[0007] The lower main shaft of this lock-type embedding machine drives the mounting shaft to rotate synchronously through the synchronous belt assembly, and then the worm gear on the mounting shaft drives the worm assembly on the mounting seat to rotate synchronously, and the worm assembly drives the horizontally connected rotary hook to rotate synchronously. The cooperation between the rotary hook and the needle on the needle bar forms a lock-type stitch, and the stitch is not easy to fall apart, thereby improving the tightness of the connection between the sewing stitch and the fabric to avoid loosening or falling off.

[0008] In the aforementioned lock-stitch sewing machine, the worm assembly, worm gear, mounting seat, and rotary hook are each provided in pairs, and the two worm assemblies, worm gears, mounting seats, and rotary hooks are symmetrically arranged on either side of the needle bar. Furthermore, by providing two needles on the needle bar, each engaged with the two rotary hooks, multiple lockstitches can be formed along the feed direction of the sewn material, meeting diverse sewing needs.

[0009] In the aforementioned locking clamp embedding machine, the timing belt assembly includes two timing pulleys disposed on the lower main shaft and the mounting shaft, respectively, with a timing belt being sleeved on the two timing pulleys. The timing belt assembly has the advantages of accurate and stable transmission, high transmission efficiency, and easy maintenance.

[0010] In the aforementioned locking clamp embedding machine, the edge of the synchronous pulley has gear teeth, the inner side of the synchronous belt has tooth patterns, and two synchronous pulleys are respectively meshed and connected to the inner ends of the synchronous belt. This structure can prevent slippage and make the transmission of the synchronous belt assembly more precise.

[0011] In the aforementioned locking clip embedding machine, the worm assembly includes two vertically arranged and meshing worms, one of which meshes with a worm wheel, and the other worm's top extends out of a mounting seat and is provided with the rotary hook. By placing the rotary hook at the top of the worm, the rotary hook rotates synchronously with the worm. The worm, driven by the worm wheel, exhibits a strong self-locking property, i.e., the worm can prevent the worm wheel from rotating reversely without external force. Furthermore, the worm assembly has the advantages of a compact structure, smooth transmission, and high operational reliability. Furthermore, the assembly can achieve forward and reverse motion under external force, providing greater flexibility and functionality. Furthermore, by providing two worms, the placement of various components can be more rationalized.

[0012] Compared with the existing technology, the advantages of this lock-type embedding machine are that it can form lock stitches, which are not easy to fall apart. At the same time, by arranging multiple needles on the needle bar, multiple lock stitches can be formed along the feed direction of the sewn object to meet diverse sewing needs.
