Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] This utility model provides a technical solution: such as Figure 1 - Figure 5 The illustrated sewing equipment for processing car seat cushions includes an operating table 1. A fitting groove 2 is provided on one side of the operating table 1. A support block 3 is fitted inside the fitting groove 2. A positioning block 4 is fitted inside the support block 3 near the operating table 1. A pushing block 5 is fixedly connected to the positioning block 4 away from the support block 3. A pushing rack 6 is fixedly connected to the pushing block 5 away from the positioning block 4. A gear 7 is rotatably connected to one side of the pushing rack 6. A support shaft 17 is rotatably connected inside the gear 7. A pressing rack 8 is meshed on the side of the gear 7 away from the pushing rack 6. A pushing component is provided at one end of the pressing rack 8.

[0021] Please see Figure 2 - Figure 5 The push assembly shown in the figure includes a spring 11, which is fixedly connected to one end of the pressing rack 8. A telescopic box 9 is fixedly connected to the side of the operating table 1 away from the support block 3. A telescopic groove 12 is opened inside the telescopic box 9. The end of the spring 11 away from the pressing rack 8 is fixedly connected to the inside of the telescopic groove 12. The push rack 6 and the pressing rack 8 are set inside the telescopic groove 12. The support shaft 17 is fixedly connected to the inside of the telescopic groove 12.

[0022] Please see Figure 1 - Figure 4 In the figure, a pressing block 13 is slidably connected inside the operating table 1 near the lower pressing rack 8. The pressing block 13 is fixedly connected to the end of the lower pressing rack 8 away from the spring 11. A telescopic rod 10 is fixedly connected between the lower pressing rack 8 and the telescopic groove 12. The telescopic rod 10 is set inside the telescopic box 9.

[0023] Please see Figure 1 and Figure 2 In the figure, the machine head 14 is fixedly connected to the side of the operating table 1 away from the telescopic groove 12. The machine head 14 is set in an "L" shape, and a sewing component is set at the end of the machine head 14 near the support block 3.

[0024] Please see Figure 2 and Figure 3 The sewing assembly shown in the figure includes a presser foot 15, which is located at one end of the machine head 14. A sewing needle 16 is installed inside the presser foot 15, which is also located at one end of the machine head 14.

[0025] Please see Figure 1 and Figure 2 In the figure, the operating platform 1 is fixedly connected to the side of the telescopic groove 12 with four sets of support legs 18 arranged in a rectangular array on one side of the operating platform 1.

[0026] Working principle: First, select the fabric and filling to be sewn. Then, select a support block 3 with relatively smooth friction with the fabric and install it inside the fitting groove 2 opened in the operating table 1. The presser foot 15 is pressed on the surface of the top layer of fabric by the machine head 14. At this time, the machine head 14 is started, and the machine head 14 controls the sewing needle 16 to sew the multiple layers of fabric. This ensures that the presser foot 15 and the support block 3 have the same friction with the fabric they are in contact with, and ensures that the fabric will not shift when pulled during sewing.

[0027] When replacing support block 3, simply press the pressing block 13 to slide it inside the operating table 1, thereby pushing the downward pressing rack 8 to slide inside the telescopic groove 12 of the telescopic box 9. The descent of the downward pressing rack 8 will drive the gear 7 to rotate outside the support shaft 17. The rotation of the gear 7 will drive the pushing rack 6 to rise, and the pushing rack 6 will push the pushing block 5, causing the pushing block 5 to disengage the support block 3 from the fitting groove 2. This allows the support block 3 to be removed from the outside of the positioning block 4 and the top of the pushing block 5. Then, select a support block 3 that matches the friction of the fabric and place it outside the positioning block 4 for positioning. Then, release the pressing block 13, and the spring 11 and the telescopic rod 10 will push the downward pressing rack 8 to slide inside the telescopic groove 12. When the presser foot 15 is pressed down to reset, the pressing block 13 will also reset to be flush with the operating table 1. During the reset process, the pressing rack 8 will drive the gear 7 to rotate in the opposite direction outside the support shaft 17, thereby causing the pushing rack 6 to descend. This allows the pushing block 5 and the positioning block 4 to descend with the pushing rack 6, so that the support block 3 can be re-embedded in the fitting groove 2. At this time, the fabric can be placed between the presser foot 15 and the support block 3, and the sewing needle 16 can sew. In this way, when the fabric to be sewn is pulled, the friction between the presser foot 15 and the fabric is the same as the friction between the support block 3 and the fabric, which can ensure that the fabric will not shift. During sewing, the support leg 18 ensures the stability of the sewing operating table 1 and the upper and lower structures of the operating table 1, ensuring that the operating table 1 will not shake.

[0028] It should be noted that this device can easily remove the support block 3 from the fitting groove 2 by simply pressing the pressing block 13, so that it can be replaced accordingly. This solves the problem that the previous bolt connection of the support block 3 made the replacement of the support block 3 more complicated and slower, thus improving the replacement efficiency of the support block 3.
