Description

Technical Field

[0001] This utility model relates to the field of airbag production, specifically to a sewing machine presser foot guide mechanism. Background Technology

[0002] An airbag is a passive safety (see vehicle safety features) protection system that works in conjunction with seat belts to provide effective crash protection for occupants.

[0003] Airbags undergo various cutting and sewing processes during production, with sewing machines playing an indispensable role in the process. Different car models often require different airbag models, so airbags are sewn into different sizes according to requirements. Existing sewing machines use presser feet mounted on the machine head to press the product being sewn. However, the external length of airbags varies depending on their size, and traditional presser feet can only press a small section, which is not suitable for different sizes of airbags and cannot provide better compression and positioning.

[0021] The utility model will now be further described with reference to the accompanying drawings and specific embodiments:

[0022] Please see Figure 1-5 According to an embodiment of the present invention, a sewing machine presser foot guide mechanism includes a table 1, a support leg 2 fixedly installed at the bottom of the table 1, a frame 3 fixedly installed at the top of the table 1, a machine head 4 installed at one end of the frame 3, a motor 5 installed at the center of the bottom of the table 1, and a pedal 6 installed at the bottom of the frame 3 for starting the motor 5. A presser bar 8 extends from the bottom of the machine head 4, a presser foot 9 is fixedly installed at the bottom end of the presser bar 8, and a sewing needle 10 is installed at the bottom of the machine head 4, with the sewing needle 10 positioned directly opposite the bottom of the presser foot 9. The presser foot 9 includes an insert plate 91, the top of which is fixedly inserted into the bottom end of the presser bar 8. A presser frame 92 is integrally provided at the bottom end of the insert plate 91, and a magnet block 93 is fixedly installed on one outer wall of the presser frame 92. A stop block 94 is provided on the outside of the magnet block 93.

[0023] The pressure bar 8 at the end of the machine head 4 can drive the presser foot 9 to move toward the table plate 1, and then use the press frame 92 to press the workpiece on the table plate 1. The stop block 94 set on the outer wall of the press frame 92 can limit the workpiece. The stop block 94 can be magnetically installed by the magnet block 93 on the outer wall of the press frame 92, which can facilitate quick replacement of the stop block 94. When using stop blocks 94 of different sizes and lengths, the size of the product can be effectively controlled when sewing.

[0024] The table 1 is also equipped with a lighting lamp 7, which can effectively illuminate the area of ​​the machine head 4, facilitating the sewing of products.

[0025] The insert plate 91 has a locking hole 95, and a locking rod 81 is inserted through the outside of the pressure rod 8, with the middle of the locking rod 81 passing through the locking hole 95. The locking rod 81, in conjunction with the locking hole 95, can easily fix the insert plate 91.

[0026] The stop block 94 has a groove 96 on its outer wall facing the pressure frame 92, and the groove 96 is adapted to the magnet block 93. By using the groove 96 to magnetically adapt to the magnet block 93, the stop block 94 can be easily and quickly disassembled and replaced.

[0027] The bottom of the pressure rod 8 has a slot (not shown in the figure), the top of the insert plate 91 is inserted into the slot, and the end of the insert plate 91 has a latch 97. The bottom of the slot has a protrusion, and the latch 97 is engaged with the outside of the protrusion. The fit between the latch 97 and the protrusion can effectively limit the insertion plate 91, making it easy for the locking rod 81 to pass through the locking hole 95.

[0028] Through the above-described solution of this utility model, the structure of this utility model is simple and the design is reasonable. The pressure frame 92 is used to press the product, and a magnet block 93 is fixed outside the pressure frame 92. A stop block 94 is assembled outside the magnet block 93 by magnetic attraction. The stop block 94 is used to limit the product. By changing the stop block 94 of different sizes, the size of the product can be controlled when sewing the product.
