Detailed Implementation

[0022] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0023] Please see Figure 1 This utility model provides an edge sewing device for knitted fabrics, including a base 1, a power cord 2, a sewing machine body 3, a sewing head 4, an extension table 5, and a multi-functional alignment device 6. The power cord 2 is connected to the back of the base 1, the sewing machine body 3 is mounted on the top of the base 1, the sewing head 4 is located at the front of the sewing machine body 3, the extension table 5 is fastened to the front of the base 1, and the multi-functional alignment device 6 is located on the top surface of the extension table 5.

[0024] Please see Figures 2-5 This utility model provides an edge sewing device for knitted fabrics. The multi-functional alignment device 6 includes a guide groove 61, a screw 62, a handwheel 63, a threaded sleeve 64, a connecting seat 65, a slide 66, a guide frame 67, a slide rail 68, and a pressing mechanism 69. A guide groove 61 is horizontally arranged on the right side of the top surface of the machine base 1. The screw 62 is horizontally rotatably installed inside the guide groove 61. A handwheel 63 is rotatably installed at the rear of the machine base 1. The handwheel 63 is directly aligned with the guide groove 61, and a transmission connection is established between the handwheel 63 and the rear end of the screw 62. A threaded sleeve 64 is threaded onto the outside of the screw 62. A connecting seat 65 is provided on the top surface of the extension platform 5, and the connecting seat 65 is along the guide groove 66. The connecting seat 65 slides inward to the inside of the groove 61. The top screw of the connecting seat 65 is connected and fixed to the threaded sleeve 64. A horizontal groove 66 is provided through the front of the bottom of the connecting seat 65. A guide frame 67 is provided at the front of the connecting seat 65. The guide frame 67 is L-shaped. A slide rail 68 is horizontally installed on the bottom back of the guide frame 67. The slide rail 68 is slidably installed inside the groove 66, so that the guide frame 67 and the connecting seat 65 are slidably connected. A positioning bolt 65a is screwed into the threaded hole at the top of the connecting seat 65. The positioning bolt 65a can be screwed into the groove 66 and abut against the top of the slide rail 68, thereby locking the sliding position of the guide frame 67. A clamping mechanism 69 is provided at the front of the guide frame 67.

[0025] To further explain, the guide groove 61 has a length of ≥8cm, which provides sufficient adjustment margin for the guide frame 67 and satisfies the ability of the guide frame 67 to move and adjust in the front and rear directions.

[0026] To further explain, the length of the slide rail 68 is the same as the length of the guide frame 67, which can provide sufficient adjustment margin for the guide frame 67 and meet the adjustment capability of the guide frame 67 in the left and right directions.

[0027] To further explain, the slide rail 68 can be slidably disassembled along the end of the slide groove 66, and the user can freely assemble the guide frame 67 according to the usage requirements. It is highly adjustable and can be assembled on-site according to the user's choice.

[0028] Please see Figures 6-7 This utility model provides an edge sewing device for knitted fabrics. The pressing mechanism 69 includes a connecting groove 691, a movable seat 692, a pressure roller 693, a slide rod 694, and a spring 695. The guide frame 67 has a longitudinally formed connecting groove 691 at its front. The movable seat 692 is slidably installed inside the connecting groove 691. The pressure roller 693 is rotatably installed at the front of the movable seat 692. The slide rod 694 is longitudinally arranged on the top surface of the connecting groove 691. The movable seat 692 is slidably sleeved under the slide rod 694. On the end surface, a spring 695 is sleeved on the outside of the slide bar 694. The top of the spring 695 abuts against the connecting groove 691, and the bottom of the spring 695 abuts against the moving seat 692. The spring 695 applies a downward elastic force to the moving seat 692, causing the moving seat 692 to move downward along the slide bar 694 and press against the bottom of the connecting groove 691. This allows the pressure roller 693 to press the fabric downward, ensuring that the fabric is pressed and flat before passing through the seam of the machine head 4, thus guaranteeing the final sewing effect.

[0029] To further explain, the length of the pressure roller 693 is ≥2cm, ensuring the pressure range of the pressure roller 693 on the fabric.

[0030] The working principle is as follows:

[0031] First, place the sewing machine body 3 on the workbench via the base 1, then connect the power cord 2 to the external power cord to power the sewing machine body 3, and finally assemble the extension table 5 with the base 1 to expand the operating space.

[0032] Secondly, by setting a multi-functional alignment device 6 on the top surface of the extension table 5, the screw 62 is rotated by turning the handwheel 63 to drive the threaded sleeve 64 to move, thereby controlling the connecting seat 65 to slide back and forth along the guide groove 61, thus adjusting the position of the guide frame 67 in the front and back directions. Then, the positioning bolt 65a is loosened to release the slide rail 68, which can then slide left and right along the slide groove 66, thereby adjusting the position of the guide frame 67 in the left and right directions. Finally, the positioning bolt 65a is tightened to lock the guide frame 67 in the current position, thus completing the position adjustment operation of the guide frame 67. The relative position of the guide frame 67 and the machine head 4 can be adjusted according to the fabric processing requirements. When the fabric is being sewn, the side of the fabric is moved towards the machine head 4 along the guide frame 67. With the position correction of the guide frame 67, the accuracy of manual operation can be improved, and the fabric deviation from the predetermined position can be avoided, which would cause the sewing line to tilt.

[0033] Third, by setting a pressing mechanism 69 at the front of the guide frame 67, a downward elastic force is applied to the movable seat 692 by the spring 695, causing the movable seat 692 to move downward along the slide rod 694 and press against the bottom of the connecting groove 691, providing downward elastic pressure to the pressure roller 693. When the fabric moves along the guide frame 67 and passes through the pressing mechanism 69, the pressure roller 693 is first lifted upward to allow the fabric to pass under it, and then the pressure roller 693 is released. The elastic force applied by the spring 695 makes the pressure roller 693 press down on the fabric surface. When the fabric passes through the pressing mechanism 69, it will be pressed and flattened by the pressure roller 693, avoiding local bulging of the fabric and affecting the sewing effect of the fabric edge.
