Abstract
Description
Technical Field
[0001] This utility model relates to the field of sewing machine technology, and in particular to a fully automatic four-sided rounded corner sewing machine. Background Technology
[0002] The fully automatic four-sided rounded corner sewing machine is a highly efficient sewing device mainly used in industries such as clothing, home textiles, upholstered furniture, and automotive interiors. This type of sewing machine can automatically complete the four-sided rounded corner sewing of fabrics. It features high speed, high precision, and easy operation. It is usually equipped with advanced control systems and drive technology, enabling automated production and high-quality sewing results. Due to its high efficiency and reliability, the fully automatic four-sided rounded corner sewing machine has been widely welcomed in the market and has become an indispensable piece of equipment for many manufacturers.
[0003] In existing technology, the raw towel material before sewing is generally larger than the finished towel after sewing. The sewing machine needle has a cutting device in front of it. Before sewing, the excess material is cut off and then the needle is sewn up. The size of the finished product after cutting and sewing is exactly in line with the size requirements of the finished product. Since the cutting blade of the sewing machine is in front of the needle and there is about 10 mm between them, there is no problem when sewing the straight edge of the towel. However, there will be a problem when sewing the four corners. This is because if the machine rotates and runs in an arc with the needle as the reference, then the position of the cutting blade is not a standard arc. As a result, the towel cut by the cutting blade will not have a standard arc at the corner, but will protrude.
[0004] Therefore, we propose a fully automatic four-sided rounded corner sewing machine. Summary of the Invention
[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a fully automatic four-sided rounded corner sewing machine.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A fully automatic four-sided rounded corner sewing machine includes a machine table, a material picking position is fixedly provided on the top of one side of the machine table, a trademark component is provided on one side of the material picking position, and a first electric slide is provided on one side of the material picking position.
[0008] As a further solution of this utility model: a servo motor is fixedly installed on the top of the first electric slide, and a fixed seat is fixedly installed on the inner side of the first electric slide. The cutting system cuts out a square blank from the whole towel blank and pulls it to the material picking position shown in the figure. After the trademark machine body automatically puts the trademark on, the pressing template comes over to press down the towel and the trademark, and then the template drives the towel.
[0009] As a further improvement of this utility model: a mounting bracket is fixedly provided at the bottom of the fixed base, and the trademark machine body is fixedly provided on the inner side of the mounting bracket. The second electric slide facilitates the adjustment of the position of the trademark machine body, and the mounting bracket facilitates the installation and fixing of the trademark machine body.
[0010] As a further embodiment of this utility model: the top of the equipment table is provided with an edge trimming component, the top of the equipment table is provided with a second electric slide, and a servo motor is fixedly provided on one side of the second electric slide. First, go to the first workstation, the cutting workstation trims the edges of the towel.
[0011] As a further improvement of this utility model: a trimming knife body is provided at the bottom of one side of the second electric slide, and an electric transmission roller is provided below the trimming knife body. The electric transmission roller is provided to facilitate the adjustment of the position of the towel during the trimming process, so as to trim it into the rounded corner fabric. The second electric slide is provided to facilitate the adjustment of the position of the trimming knife body before moving to the second work station.
[0012] As a further improvement of this utility model: a sewing machine body is fixedly installed on the top of the equipment table on the side away from the material picking position, and a sewing table and sewing machine station are fixedly installed below the sewing machine body for edge sewing. The towel is cut into a standard shape, and the sewn product is beautiful and meets the sewing requirements of most high-end towels.
[0013] Compared with the prior art, this utility model provides a fully automatic four-sided rounded corner sewing machine, which has the following beneficial effects:
[0014] This utility model, by installing a trademark component, allows the cutting system to cut a square blank from the entire towel blank and pull it to the material picking position as shown in the figure. After the trademark machine body automatically places the trademark, the pressing template comes over to press down the towel and the trademark. Then the template moves the towel. The setting of the second electric slide facilitates the adjustment of the position of the trademark machine body, and the setting of the mounting frame facilitates the installation and fixing of the trademark machine body.
[0015] This invention first proceeds to the first workstation, the cutting station, where the towel is trimmed. The electric drive roller allows for easy adjustment of the towel's position during the trimming process, shaping it into the rounded corner fabric required. The second electric slide allows for easy adjustment of the trimming knife's position. Then, the towel proceeds to the second workstation, the sewing machine station, where it is edge-sealed. The towel is cut to a standard shape, and the sewn product is aesthetically pleasing, meeting the sewing requirements of most high-end towels.
