Description

Technical Field

[0001] This utility model relates to the field of seamless sewing machine technology, specifically a seamless sewing machine for floor socks. Background Technology

[0002] Seamless sewing machines primarily utilize ultrasonic vibrations to generate energy, performing overlapping and cutting of fabric edges and automatically fusing them together to achieve seamless welding. This technology not only boasts high welding speed and strength but also produces aesthetically pleasing welds with excellent sealing performance, low energy consumption, and ease of operation, making it one of the future directions for sewing machine development.

[0003] The design and function of the working head of a seamless sewing machine differ from those of a traditional sewing machine, primarily in that it employs ultrasonic technology to achieve seamless stitching. This is mainly achieved through the pressing of a welding head and a pressure roller. The welding head is responsible for transmitting ultrasonic energy to the fabric, heating and melting it to achieve seamless bonding. During this process, the downward pressure of the pressure roller is mainly driven by a cylinder. However, the extension of the cylinder's output end is usually either fully extended or fully retracted, making it difficult to control the extension length. This results in significant differences in the pressing force when encountering fabrics of different thicknesses. Furthermore, when sewing different positions, it is often necessary to switch between a disc pressure roller and a lace pressure roller. Therefore, to facilitate normal operation, a seamless sewing machine that can quickly switch pressure rollers and adjust the downward pressure of the pressure rollers needs to be designed.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4 This utility model provides a technical solution: it includes a processing table 1 and a sewing machine body 2. The sewing machine body 2 is fixed at the middle position of the upper end of the processing table 1. An ultrasonic welding head 13 is installed at the upper end of the processing table 1, aligned with the position of the sewing machine body 2. A cylinder 4 is installed at the end of the sewing machine body 2. A telescopic plate 5 is fixed at the output end of the cylinder 4. A pressure roller 3 is installed at the bottom of the telescopic plate 5 through a quick-release assembly. The position of the pressure roller 3 is aligned with the ultrasonic welding head 13. An adjusting sleeve 6 is slidably connected to the end of the sewing machine body 2. The upper end of the cylinder 4 is fixed inside the adjusting sleeve 6. A threaded sleeve 7 is rotatably connected to the upper end of the sewing machine body 2. The upper end of the adjusting sleeve 6 passes through the threaded sleeve 7 and is threadedly connected to the threaded sleeve 7. A support frame 11 is fixed at the bottom of the processing table 1. A foot pedal 12 is installed on the support frame 11.

[0019] The quick-release assembly includes a plug 31 and a through hole 51. The through hole 51 is formed on the telescopic plate 5. The pressure roller 3 is rotatably connected to the front end of the plug 31. The end of the plug 31 is inserted into the through hole 51. A positioning plate 32 is fixed on the plug 31. The positioning plate 32 abuts against the side wall of the telescopic plate 5. A rear groove 52 is formed on the upper rear side of the through hole 51. A positioning rod 53 is installed in the rear groove 52. A positioning hole 33 is formed at the upper end of the plug 31. The bottom of the positioning rod 53 is inserted into the positioning hole 33. A telescopic groove 54 is formed at the upper end of the rear groove 52 and at a position corresponding to the positioning rod 53. A telescopic spring 55 is fixed between the top of the telescopic groove 54 and the top of the positioning rod 53. A pull block 56 is fixed at the middle position of the outer side of the positioning rod 53.

[0020] A pair of limiting blocks 61 are fixed on the outer side of the bottom of the adjusting sleeve 6. A limiting groove 21 is opened in the sewing machine body 2 at a position corresponding to the limiting blocks 61. The limiting blocks 61 are slidably connected in the limiting groove 21. A limiting plate is fixed on the outer side of the upper end of the adjusting sleeve 6. By using the limiting blocks 61, it can be ensured that the adjusting sleeve 6 can only move up and down, and the limiting plate can limit its descent range.

[0021] Working principle: First, connect the entire device to an external power source. Then, place the floor sock fabric between the pressure roller 3 and the ultrasonic welding head 13. Driven by the cylinder 4, the pressure roller 3 is pressed down to cooperate with the ultrasonic welding head 13 to achieve seamless stitching. During this process, the rotation of the threaded sleeve 7 and the limiting action of the limiting block 61 can drive the adjusting sleeve 6 to rise and fall, and drive the cylinder 4 to rise and fall as a whole. When the output end of the cylinder 4 drives the pressure roller 3 to press down, the bottom height of the pressure roller 3 can be adjusted. Thus, when pressing fabrics of different thicknesses, the pressure on the fabric can be adjusted. Next, pull the pull block 56. When the telescopic spring 55 is compressed, the positioning rod 53 is pushed upward, so that the bottom of the positioning rod 53 is pulled out from the positioning hole 33. The insertion block 31 can be quickly pulled out for replacement of different pressure rollers 3. After the insertion block 31 is inserted into the insertion hole, the bottom of the positioning rod 53 is inserted into the positioning hole 33 to fix the insertion block 31 and the positioning block.
