[0023] The utility model will be described in detail in combination with the drawings.

[0024] As Figures 1-3 ​As shown, a mattress core of a mattress, comprising a plurality of cores connected in parallel, the core comprising a plurality of spring cores 12 stitched together, and a positioning cloth 18 connecting two adjacent cores, the spring core 12 comprising a spring body 13 and a core bag 14 covering the spring body 13, and the core bag 14 and the core bag 14 are provided with a stitching edge 15, and the positioning cloth 18 is arranged along the length direction of the core, and the positioning cloth 18 is sequentially connected with the stitching edge 15 of the core bag 14 of the first row and the second row.

[0025] Under the action of the positioning cloth 18, the positioning cloth 18 is connected with the stitching edge 15 of the spring core 12, and the positioning cloth 18 is arranged along the length direction of the core, so that a plurality of cores form a whole; the distance between the two adjacent spring cores 12 is shortened, and when one of the spring cores 12 is lifted, the whole remains flat structure, and the spring body 13 will not be deformed, and the stability of the elastic support after processing into a mattress is further improved.

[0026] Specifically, the core is divided into first cores 1 and second cores 11 with the same length, and the first cores 1 and the second cores 11 are arranged alternately, and the distance between the two adjacent spring cores 12 is the same. The first cores 1 and the first cores 1 are arranged in parallel and spaced apart in alignment, and the second cores 11 and the second cores 11 are arranged in parallel and spaced apart in alignment. One of the spring cores 12 of the second core 11 is located between the two adjacent spring cores 12 of the first core 1. In this embodiment, the above arrangement is adopted, so that the distance between the two adjacent spring cores 12 is further shortened, and the gap area is reduced. Under the same area, more spring cores 12 can be arranged, so that the stability of the elastic support of the whole is further improved.

[0027] Further, the core bag 14 and the core bag 14 are integrally connected, the two sides of the core bag 14 are respectively formed with the stitching edge 15, and the two adjacent spring cores 12 are connected through the stitching edge 15. The stitching edge 15 is arranged along the length direction of the core bag 14, and after the two adjacent spring cores 12 are connected through the stitching edge 15, the spring core 12 and the spring core 12 are connected through the long side, which can further stabilize the integrated structure between the two adjacent spring cores 12.

[0028] Further, the positioning cloth 18 is arranged in a meandering manner along the length direction of the first core 1 and the second core 11 in turn, and when the positioning cloth 18 is arranged along the length direction, it will pass through the spring core 12 of the first core 1 and the spring core 12 of the second core 11 in turn, that is, the stitching edge 15 of the first core 1 is located on the left side of the positioning cloth 18, and the stitching edge 15 of the second core 11 is located on the right side of the positioning cloth 18, and the two adjacent positioning cloths 18 are integrally connected, so that all the positioning cloths 18 form an integrated structure.

[0029] Further, the width of the positioning cloth 18 is greater than 1 / 2 of the length of the spring core package 12, the middle of the stitched edge 15 is provided with a middle stitching part 17 along the length direction, and the edge stitching parts 16 are arranged on both sides of the middle stitching part 17. The positioning cloth 18 is stitched and connected with the middle stitching part 17 of the stitched edge 15. When the positioning cloth 18 passes through the stitched edge 15 of the first core body 1 and the second core body 11 in turn, it is stitched and connected with the middle stitching part 17 of the stitched edge 15, that is, the spring core package 12 of the first core body 1 is connected with the spring core package 12 of the second core body 11 through the positioning cloth 18.

[0030] Preferably, the core package bag 14 and the positioning cloth 18 are both made of non-woven fabric material. Non-woven fabric can have certain waterproof performance and can block water penetration while maintaining air permeability; has a moisture-proof effect: due to its non-absorbing characteristics, non-woven fabric can effectively prevent the intrusion of water vapor and protect the mattress from moisture.

[0031] Preferably, the stitched edges 15 between the two adjacent spring core packages 12 are stitched and connected by ultrasonic seamless stitching.

[0032] Compared with the traditional stitching method, the ultrasonic seamless stitching is faster and can greatly improve the production efficiency. Using ultrasonic seamless stitching technology can complete large-area stitching in a short time, while the traditional stitching method takes more time. High stitching quality: ultrasonic seamless stitching can achieve tight and uniform stitching effect, and the strength of the stitched part is high and the sealing performance is good. Environmentally friendly and energy-saving: this technology does not need to use needle and thread and glue and other auxiliary materials, reducing the generation of waste and being more friendly to the environment. At the same time, the energy consumption of ultrasonic equipment is relatively low, which can save energy costs in large-scale production.

[0033] Preferably, the stitched edges 15 between the two adjacent spring core packages 12 are stitched and connected by sewing seamless stitching. The connection method of sewing stitching has uniform, straight, smooth and neat appearance. The fabric feeding mechanism of the sewing machine can accurately control the moving speed and direction of the fabric, so that the needle stitches according to the predetermined trajectory, and the situation of skew or uneven needle spacing that may occur in manual stitching does not occur.

[0034] Further, since the positioning cloth 18 is arranged along the length direction, it will pass through the spring core package 12 of the first core body 1 and the spring core package 12 of the second core body 11 in turn, so that the positioning cloth 18 between the first core body 1 and the second core body 11 is arranged in a continuous "W" shape, forming a stable connection structure.

[0035] Further, the width of the sewing edge 15 is greater than 1 cm, and with this length, space is reserved for the sewing connection of two adjacent spring core packs 12, and space is also reserved for the sewing connection of the positioning cloth 18, so that the middle sewing part 17 and the edge sewing part 16 are not overlapped, and the stability after sewing is better.

[0036] In summary, the utility model has the above-mentioned excellent characteristics, and can improve the performance of the previous technology and has practicality, and becomes a product with practical value.

[0037] The above is only a preferred embodiment of the utility model, and for those skilled in the art, according to the idea of the utility model, the specific implementation mode and application range can be changed, and the content of the specification should not be understood as limiting the utility model.
