Embodiment Construction
[0024] Below in conjunction with accompanying drawing, structural principle and working principle of the present invention are specifically described:
[0025] Relevant detailed description and technical contents of the present invention are as follows with regard to coordinating accompanying drawings now:
[0026] see figure 1 , figure 2 and Figure 5 As shown, the present invention provides a sewing machine with an electromagnetic automatic cutting device, which is used to sew two pieces of cloth 4 together. It includes a main driving machine part 1 and a sewing platform 2 located below the main driving machine part 1. , and an electromagnetic control structure 3 . The main actuator unit 1 includes a cloth cutting knife group 11 for cutting the two fabrics 4 at the beginning of sewing, a sewing machine group 12 for stitching the two fabrics 4 together, and a sewing machine at the beginning and end of sewing, respectively. Trimming thread 41 (also shown in Figure 4 ) o...

Provided is a sewing machine with an automatic electromagnetic cutting device. The sewing machine with the automatic electromagnetic cutting device comprises a main actuator portion and an electromagnetic pushing device, wherein the main actuator portion is provided with an upper thread cutting knife and a lower thread cutting knife, the electromagnetic pushing device is provided with an electromagnetic portion, a driving rod and a connecting portion, the driving rod is repelled by the electromagnetic portion to carry out a thread cutting stroke, the connecting portion is connected with the upper thread cutting knife and is in linkage with the driving rod, and the electromagnetic pushing device is in linkage with the upper thread cutting knife to cut off a thread end. The electromagnetic pushing device is driven by electric power, and except the sewing machine, a gas compression device which occupies the space and causes additional cost does not need to be additionally arranged. Due to the fact that the electromagnetic pushing device comprises a plurality of telescopic shaft rods which are connected with the connecting portion, the degree of stress of the connecting portion is balanced, stability of the connecting portion is improved, and the phenomenon that the thread end cannot be cut due to the fact that the upper thread cutting knife and the lower thread cutting knife are staggered is avoided.
Description
technical field [0001] The invention relates to a sewing machine, in particular to a sewing machine with an electromagnetic automatic cutting device. Background technique [0002] The sewing machine for double-cloth sewing is used to join and sew the edges of two pieces of cloth, so the sewing machine for double-cloth sewing (hereinafter referred to as "sewing machine") has a sewing tool set to sew two pieces of cloth, the sewing tool The set includes the feed dog, the feed dog platform, multiple knitting needles and cotton threads, and other necessary interlocking mechanisms. Since the sewing tool set is an existing structure, its detailed structure and actions will not be repeated here. [0003] After the sewing tool set starts to sew two pieces of fabric, the edges of the two pieces of fabric are joined by a network of threads knitted by multiple knitting needles. Cut off the thread with a tool. However, with the rapid advancement of sewing machine technology, there are...
