[0035] like Figure 1 、 Figure 2 and Figure 3As shown, the embodiment of the present invention provides a car seat cushion sewing device, including a workbench 1 and an electric sewing machine 5. A limiting groove 3 is provided on one side of the workbench 1, and the limiting groove 3 is slidably connected to a movable plate 12. The upper part of the movable plate 12 is connected to the limiting plate 13. A sliding groove 14 is provided on the side of the limiting plate 13 away from the limiting groove 3. A smoothing component 2 is installed in the sliding groove 14. A telescopic plate 6 is slidably engaged with the side of the workbench 1 away from the limiting groove 3. The limiting plate 13 slides in contact with the upper surface of the workbench 1. The electric sewing machine 5 is fixedly installed on the side of the upper surface of the workbench 1 close to the limiting groove 3. Two groups of base frames 7 are installed on the lower surface of the workbench 1. A mounting plate 9 is threadedly installed on the side surface of the workbench 1 away from the limiting groove 3. The side surface of the mounting plate 9 is connected to a side plate 8. The side plate 8 is threaded with a bolt 10. The bolt 10 is against the side surface of the telescopic plate 6. The movable plate 12 is threadedly connected to a screw 11. The end of the screw 11 is connected to the knob 4. The screw 11 is rotatably connected to the workbench 1. 11 is threadedly connected to the movable plate 12. When sealing the edge of the car seat cushion, first adjust the telescopic plate 6 according to the size of the car seat cushion. Specifically, first release the limit of the side of the telescopic plate 6 on the bolt 10, and then pull the telescopic plate 6 to move horizontally. When the area of the telescopic plate 6 and the workbench 1 is adapted to the car seat cushion, turn the bolt 10 to fix the side of the telescopic plate 6. Then, adjust the distance between the limit plate 13 and the needle mouth of the electric sewing machine 5 according to the distance between the stitching line and the folding part of the edge sealing material. Specifically, turn the knob 4. The rotation of the knob 4 drives the screw 11 to rotate. The rotation of the screw 11 drives the movable plate 12 to move horizontally. The horizontal movement of the movable plate 12 drives the limit plate 13 and the smoothing component 2 to move horizontally. When the distance between the needle mouth of the electric sewing machine 5 and the limit plate 13 is adapted to the distance between the stitching line and the folding part of the edge sealing material, stop turning the knob 4. Then, fit the edge sealing material to the car seat cushion, and align the car seat cushion and the edge sealing material as a whole with the smoothing component 2 and insert them.

[0036] like Figures 1 to 5As shown, the smoothing component 2 includes a lifting plate 201, the side of the lifting plate 201 is in sliding contact with the limit plate 13, a connecting plate 204 is connected to the middle position of the side of the lifting plate 201, the connecting plate 204 is slidably adapted to the slide groove 14, a spring 202 is installed on the upper surface of the connecting plate 204, the upper end of the spring 202 is fixedly installed inside the limit plate 13, the connecting plate 204 is slidably connected to the limit rod 205, the limit rod 205 is fixedly installed inside the limit plate 13, a plurality of groups of evenly distributed vertical rods 207 are installed on the lower surface of the lifting plate 201, the lower end of the vertical rod 207 is installed with a bottom plate 206, the lower part of the bottom plate 206 is in contact with the upper surface of the workbench 1, and the bottom plate 20 6 is connected to the side with an arc plate 203. The car seat cushion and the edge sealing material are aligned with the arc plate 203 as a whole and inserted until the car seat cushion, the edge sealing material and the limit plate 13 are in contact. When the car seat cushion and the edge sealing material are inserted, the arc plate 203 is forced to move upward. The upward movement of the arc plate 203 drives the bottom plate 206 to move upward. The upward movement of the bottom plate 206 drives the vertical rod 207 to move upward. The upward movement of the vertical rod 207 drives the lifting plate 201 and the connecting plate 204 to move upward. When the connecting plate 204 slides upward along the limit rod 205, the spring 202 is compressed. Then the spring 202 rebounds and drives the arc plate 203 and the bottom plate 206 to contact the upper surface of the car seat cushion and the edge sealing material.

[0037] The working principle of the technical solution provided by the utility model is as follows:

[0038] When sealing the edge of the car seat cushion, first adjust the telescopic plate 6 according to the size of the car seat cushion. Specifically, first release the limit of the bolt 10 on the side of the telescopic plate 6, then pull the telescopic plate 6 to move horizontally. When the area of the telescopic plate 6 and the workbench 1 is adapted to the car seat cushion, turn the bolt 10 to fix the side of the telescopic plate 6. Through the arrangement of the bolt 10 and the telescopic plate 6, it is convenient to adjust the operating table according to the size of the car seat cushion, so as to prevent a part of the car seat cushion from falling on the right side of the workbench 1 and causing pulling force, which requires manual support, thus saving manpower.

[0039] Then, according to the distance between the suture line and the folded part of the edge banding material, the distance between the limiting plate 13 and the needle mouth of the electric sewing machine 5 is adjusted. Specifically, the knob 4 is turned, and the rotation of the knob 4 drives the screw 11 to rotate. The rotation of the screw 11 drives the movable plate 12 to move horizontally. The horizontal movement of the movable plate 12 drives the limiting plate 13 and the smoothing component 2 to move horizontally. When the distance between the needle mouth of the electric sewing machine 5 and the limiting plate 13 is adapted to the distance between the suture line and the folded part of the edge banding material, the knob 4 is stopped from being turned. Through the setting of the knob 4, the screw 11, the movable plate 12 and the limiting plate 13, one end of the edge banding of the car seat cushion is always in contact with the limiting plate 13, ensuring that the reserved size of the gap between the suture line and the edge banding material is relatively uniform, thereby improving the edge banding effect.

[0040] Then, the edge banding material is fitted with the car seat cushion, and the car seat cushion and the edge banding material are aligned with the arc plate 203 as a whole and inserted until the car seat cushion, the edge banding material and the limit plate 13 are in contact. When the car seat cushion and the edge banding material are inserted, the arc plate 203 is forced to move upward, and the arc plate 203 moves upward to drive the bottom plate 206 to move upward, and the bottom plate 206 moves upward to drive the vertical rod 207 to move upward, and the vertical rod 207 moves upward to drive the lifting plate 201 and the connecting plate 204 to move upward, and the connecting plate 204 compresses the spring 202 when it slides upward along the limit rod 205, and then the spring 202 is elastic. The spring 202 rebounds to drive the arc plate 203 and the bottom plate 206 to contact the upper surface of the car seat cushion and the edge banding material, and then the electric sewing machine 5 is started to push the car seat cushion and the edge banding material toward the electric sewing machine 5. When pushing the car seat cushion and the edge banding material toward the electric sewing machine 5, the smoothing component 2 prevents the edge banding material from warping, and the operator does not need to smooth the edge banding material frequently, reducing the operator's workload. By setting the smoothing component 2, the edge banding material can be prevented from warping, and the operator does not need to smooth the edge banding material frequently, reducing the operator's workload.

To provide a thorough understanding of this invention, specific details are described in detail in the following preferred embodiments of this invention, but those skilled in the art will be able to fully understand this invention without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of this invention, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0042] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
