[0019] like Figures 1 to 4As shown, the utility model relates to a sewing disc machine booster, including a shaft 1, the bottom of the shaft 1 is rotatably connected to a fixed bearing 2, the fixed bearing 2 is arranged at the center of the sewing disc, the edge of the sewing disc is a plurality of needle bodies, the sewing disc is a prior art, so it is not described in detail, the fixed bearing 2 can be directly installed in the center of the sewing disc, the design of the fixed bearing 2 does not affect its rotation, the outer periphery of the upper half of the shaft 1 is provided with an extension rod 3, the end of the extension rod 3 away from the shaft 1 is provided with a fixed seat 4, a crank 9 is installed on the fixed seat 4, the end of the crank 9 is provided with a bent handle 16, the end of the bent handle 16 is provided with a hand guard 17, the hand guard 17 serves to prevent end processing burrs In order to protect the machine from scratches, two pressure bearings 10 are installed on the crank 9, and a pressure gap is set between the pressure bearings 10. The pressure gap is adapted to the sum of the thickness of the textile and the needle at the edge of the sewing disc. A fixed edge piece 5 is provided on one side of the fixed seat 4. The fixed edge piece 5 is a blade-shaped structure. The fixed edge piece 5 is close to the edge of the sewing disc and is provided with a curling groove 7. The side of the curling groove 7 is provided with an anti-slip notch 12 provided on the fixed edge piece 5. The anti-slip notch 12 has the functions of hooking and enhancing friction through the protruding tip, and plays a role in auxiliary positioning. A lower extension rod 6 is provided on the other side of the fixed seat 4. A booster rubber wheel 8 is provided on the outer periphery of the lower extension rod 6. The lower surface of the booster rubber wheel 8 contacts the upper surface of the sewing disc edge.

[0020] Working principle: Since the curling groove 7 is in basic contact with the edge needle of the seam disc, it only needs to be inserted into the partial area of ​​the head end of the textile to control the small edge. Then turn the handle 16 to open the edge pressing gap between the two edge pressing bearings 10. During the rolling process, the textile can be pressed. At the same time, since the boosting rubber wheel 8 is in contact with the upper surface of the seam disc edge, the textile can be pushed during the reciprocating rolling process along the edge of the seam disc, and the wrinkled parts can be pushed to further play an auxiliary role.

[0021] Although the above structure can play an auxiliary role, it is not well applicable to different sewing machines. In order to improve its applicability;

[0022] The booster rubber wheel 8 is provided with a fixed ring 14 sleeved on the outer periphery of the lower extension rod 6. The booster rubber wheel 8 can rotate freely on the fixed ring 14. The fixed ring 14 is provided with a tightening screw 13. The centers of the two pressure bearings 10 are also rotatably connected to the fixed ring 14. The fixed ring 14 is sleeved on the outer periphery of the crank 9 in a free sliding manner. The outer periphery of the crank 9 is threadedly fixed with two adjusting nuts 15 that constrain the pressure gap.

[0023] By adjusting the two adjusting nuts 15, the gap can be adjusted according to the thickness of the textile or the seam disc to achieve a better edge pressing effect. The height adjustment of the booster rubber wheel 8 can adapt to seam discs of different heights.

[0024] Moreover, one end of the extension rod 3 passes through the shaft rod 1, and a fastener for pressing the extension rod 3 is fixed to the top of the shaft rod 1 with a thread; the fixed edge piece 5 and the lower extension rod 6 pass through the fixed seat 4 and are provided with an adjusting screw button 11 on the outside, and one end of the adjusting screw button 11 presses against the fixed edge piece 5 or the lower extension rod 6 and is threadedly connected to the fixed seat 4;

[0025] By means of the threaded connection and the pressing fixation at one end, the spacing can be adjusted to accommodate different sizes of seam discs, ensuring that the curling groove 7 is fitted with the edge of the seam disc.

[0026] The embodiments disclosed in the present invention are preferred embodiments, but are not limited to them. Ordinary technicians in this field can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. As long as they do not deviate from the spirit of the present invention, they are all within the scope of protection of the present invention.
