The presser foot and the pressing edge roller are arranged up and down, and the glue spraying nozzle is arranged between the presser foot and the pressing edge roller. The glue outlet of the glue spraying nozzle faces the central axis of the presser foot or the pressing edge roller.

[0007] In some embodiments, there are two glue spraying nozzles.

[0008] In some embodiments, the glue outlets of the two glue spraying nozzles are on the same horizontal line.

[0009] The beneficial effects of the utility model are as follows:

[0010] The surface cover structure and its flattening processing equipment can strengthen the hardness and strength on both sides of the stitches by adhering the seam allowance to the bottom of the appearance surface, ensure the smooth appearance effect of the seat surface cover, avoid problems such as stitch distortion, stitch arrangement, and unsightly appearance at the arc chamfer transition of the surface cover, improve the appearance quality of the product, increase the efficiency of fixing the surface cover on the automobile seat, reduce after-sales rework and have low cost, are applicable to the application of all automobile seat surface covers in the industry, and enhance the product competitiveness.

[0012] Figure 2 It is a schematic structural diagram of a flattening processing device;

[0013] The reference numerals and names in the figure correspond as follows: 11, appearance surface; 12, seam allowance; 13, sewing thread; 14, glue; 21, sewing machine body; 22, presser foot; 23, edge pressing roller; 24, glue spraying nozzle. Specific embodiments

[0014] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0015] Please refer to Figure 1 , the present invention provides a technical solution: a seat cover structure, including two seat covers, which are connected by a sewing thread 13. The seat cover forms an appearance surface 11 and a seam allowance 12 under the separation of the sewing thread 13. The appearance surface 11 is the part of the seat cover facing the passenger, and the seam allowance 12 is the part of the seat cover facing the seat. The seam allowance 12 and the appearance surface 11 are fixedly connected by pasting with glue 14. The seam allowance 12 is fixed below one end of the appearance surface 11 close to the sewing thread 13, which increases the hardness and strength of the seat cover near the sewing thread 13, so that the sewing thread 13 can be kept straight and the seat cover can be kept crisp when the seat cover is fixed on the seat foam.

[0016] Please refer to Figure 2 , a flattening processing device for processing the above seat cover structure, including a sewing machine body 21, a presser foot 22, an edge pressing roller 23 and a glue spraying nozzle 24. The presser foot 22, the edge pressing roller 23 and the glue spraying nozzle 24 are respectively arranged on the sewing machine body 21. The presser foot 22 and the edge pressing roller 23 are arranged up and down. The edge pressing roller 23 rotates in place. The presser foot 22 is the presser foot 22 of a general sewing machine. During operation, the presser foot 22 moves up and down and pushes the material forward. The glue spraying nozzle 24 is arranged between the presser foot 22 and the edge pressing roller 23. There are two glue spraying nozzles 24, which are respectively arranged on both sides of the central axis of the presser foot 22 or the edge pressing roller 23. The glue outlet of the glue spraying nozzle 24 faces the other glue spraying nozzle 24, and the glue outlets of the two glue spraying nozzles 24 are on the same horizontal line.

[0017] Working principle and usage process of the utility model: Two face covers are connected by a sewing thread 13. After connection, the seam allowance 12 of the face cover faces the presser foot 22, and the appearance surface 11 faces the edge pressing roller 23. The sewing thread 13 is placed at the center point between the presser foot 22 and the edge pressing roller 23. The glue outlets of the two glue spray nozzles 24 are respectively directed at the corresponding positions between the seam allowance 12 and the appearance surface 11. When the device works, the glue spray nozzles 24 spray glue between the seam allowance 12 and the appearance surface 11, that is, on both sides of the sewing thread 13. The presser foot 22 presses the seam allowance 12 flat towards the appearance surface 11, and the edge pressing roller 23 assists the presser foot 22 in the flattening operation and facilitates the forward movement of the face cover. Finally, the seam allowance 12 and the appearance surface 11 are fixedly adhered through the glue 14.

[0018] Finally, it should be noted that the above are only preferred examples of the utility model and are not used to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the utility model shall be included within the protection scope of the utility model.
