[0033] Embodiment 1

[0034] The embodiments of the application provide a seamless quilt, referring to Figure 1 , Figure 2 , comprising an upper layer 100, a lower layer 200, and a core material 300 wrapped between the upper layer and the lower layer, by setting a plurality of predetermined areas 400 corresponding to the upper layer 100 and the lower layer 200, referring to Figure 3, predetermined area 400 is provided with point glue 401 formed by point glue machine, and the point glue 401 is arrayed to form dense point glue, and the upper layer 100 and the lower layer 200 are fixed by glue through the core material 300 to form a seamless quilt with a three-layer structure.

[0035] Wherein, the upper layer 100 and the lower layer 200 define a space for placing the core material 300, and the upper layer 100 and the lower layer 200 can be two independent quilt materials, which are arranged above and below the core material 300 to wrap the core material 300, respectively; or the upper layer 100 and the lower layer 200 can be a whole quilt material, which is folded to form the upper layer 100 and the lower layer 200 wrapping the core material 300.

[0036] For example, the core material 300 can be a warm-keeping medium filled between the upper layer 100 and the lower layer 200, such as common down, silk, wool, cotton, and fiber; or the core material 300 can be a whole core material pre-made by a warm-keeping medium, such as latex sheet, polyester fiber sheet, or mixed material sheet. For the non-integrated core material, the edges of the upper layer 100 and the lower layer 200 should be fixedly connected to close the core material 300; and for the integrated core material, the edges of the upper layer 100 and the lower layer 200 can be intermittently fixedly connected to wrap the core material.

[0037] In further embodiments, the predetermined area 400 includes arrayed predetermined areas in the middle of the quilt, which can be square, diamond, flower, strip, circle, oval, T-shaped, Y-shaped, etc. In the predetermined area, the core material should be avoided, i.e. the core material corresponding to the predetermined area should be left empty, so that the upper layer 100 and the lower layer 200 can be fixed by glue through the left empty area to form a connecting part in the predetermined area 400, which can be used to limit the core material, and the predetermined area 400 can be arrayed to form multiple arrayed connecting parts to limit the core material. For the filled core material, the predetermined area 400 is naturally left empty, and the connecting part can be formed first, and then the core material is filled. For the integrated core material, the integrated core material should be pre-punched in the predetermined area 400, and then the upper layer 100 and the lower layer 200 are fixed by glue in the predetermined area 400 to form the connecting part, so that the limiting and fixing effect is better, and the integrated core material is less likely to move.

[0038] For example, the upper layer 100 and the lower layer 200 are conventional cloth, quilt material, fabric, etc., and the edges of the upper layer 100 and the lower layer 200 are seamlessly connected, as shown in Figure 4 The edge of the lower layer 200 is also provided with a circle of dense point glue formed by the point glue machine towards the inner side of the upper layer 100, and the edge of the upper layer 100 and the edge of the lower layer 200 are fixed by glue to close the core material 300. The fixed position of the edge of the upper layer 100 and the lower layer 200 is not limited to the edge, but can be close to the edge.

[0039] In further embodiments, referring to Figure 5 The integrated core material 300 is a preform and has a composite structure including a double-layer composite, one layer being a weakly elastic layer 300-1 and the other layer being an elastic layer 300-2. The weakly elastic layer 300-1 has a smaller elasticity than the elastic layer 300-2. The integrated core material is used for a seamless quilt. When a user sleeps, the quilt has different sleeping feelings on the two sides, and the user can freely choose the direction of one side facing the user. In addition to elasticity, the layered structure with different air permeability, the layered structure with different warmth retention capacity, and the layered structure with different loft can be provided to bring different sleeping feelings to the user. Similarly, a multi-layer composite structure can be provided, and the multi-layer composite layers are made of materials with different elasticity, different air permeability, different warmth retention capacity, or different loft.

[0040] In further embodiments, the point-like glue produced by the dispensing machine includes multiple types, such as UV glue, hot melt glue, wet curing glue, silicone glue, and fast-drying glue. For process convenience, wet curing glue or hot melt glue is recommended. When wet curing glue is used, the core material 300 and the upper layer 100 should be placed on the lower layer 200 as soon as possible after the dispensing of the lower layer 200 is completed, and pressure should be maintained on the upper layer 100 and the lower layer 200 to keep the upper layer 100 in contact with the lower layer 200 until the wet curing glue is cured. When hot melt glue is used, in addition to maintaining pressure on the upper layer 100 and the lower layer 200, the glue needs to be heated after the dispensing of the lower layer 200 is completed and the core material 300 and the upper layer 100 are placed on the lower layer 200, for example, by heating the entire body to melt the point-like glue and glue the upper layer 100 and the lower layer 200.

[0041] It can be understood that the predetermined area 400 is a non-physical concept. The distribution of the predetermined area 400 on the lower layer 200 and the shape of the predetermined area 400 are determined when the seamless quilt is designed, and the relevant distribution and shape information are input into the control program of the dispensing machine. The dense point-like glue formed by the dispensing machine on the lower layer 200 defines the physical distribution and shape of the predetermined area 400. For different positions of the predetermined area 400, the dispensing machine can form point-like glue with different densities, for example, for the predetermined area 400 near the center of the quilt, the point-like glue can be formed to be relatively sparse, and for the predetermined area 400 near the edge of the quilt, the point-like glue can be formed to be relatively dense; similarly, for different positions of the predetermined area 400, the dispensing machine can form point-like glue with different glue amounts to enhance the local adhesive stability.

[0042] The seamless quilt provided by the embodiment is formed by the point-like glue formed by the point-by-point of the glue dispenser, and the point-like glue limits the entity shape and distribution of the predetermined area 400, so that the flexibility of the predetermined area 400 can be realized. In addition, the point-like glue with different densities or the point-like glue with different glue amounts can be formed by the point-by-point of the glue dispenser, and the flexibility of the seamless quilt design can be realized by the glue dispenser.

[0043] In a further embodiment, referring to Figure 8 The elastic polyurethane glue is dispensed on the lower layer 200 forming the edge of the seamless quilt by the glue dispenser 600, the elastic polyurethane glue is foamed to form a soft elastic edge intermediate layer 700 with a certain thickness, and the upper layer 100, the intermediate layer 700 and the lower layer 200 are fixedly connected to seal and wrap the core material 300. The edges of the seamless quilt are fixed by the elastic polyurethane glue, and the polyurethane glue has both bonding performance and elastomer characteristics, so that the use of the seamless quilt is more soft and comfortable.

[0044] In a further embodiment, referring to Figure 9 The edges of the seamless quilt are provided with a hem 800, the edges of the upper layer 100 and the lower layer 200 are arranged in the hem 800, and the hem 800 is a separate piece.

[0045] Or the hem 800 is composed of the edges of the upper layer 100 or the lower layer 200, and the edges of the upper layer 100 or the lower layer 200 are folded to be arranged outside the other side to form the hem.

[0046] The edges of the upper layer and / or the lower layer are arranged to be fixed by gluing, and the core material is sealed and wrapped.

[0047] The edges of the seamless quilt are fixedly connected by the upper layer 100 and the lower layer 200, or the edges of the upper layer 100, the intermediate layer 700 and the lower layer 200 are fixedly connected, and the edges of the composite material are further provided with the hem 800, so as to avoid damage to the edge shape due to friction in the use process, and prolong the service life of the subsequent use of the seamless quilt. The hem 800 can be a separate piece of material, or the width / length of the upper layer 100 is greater than the width / length of the lower layer 200, and the edges of the upper layer 100 are folded to cover the edges of the lower layer 200 to form the hem. Or, the width / length of the upper layer 100 is less than the width / length of the lower layer 200, and the edges of the lower layer 200 are folded to cover the edges of the upper layer 100 to form the hem. The hem is fixed by gluing to seal and wrap the core material.

[0048] Embodiment 2

[0049] The application further provides a glue coating device for manufacturing a seamless quilt, which is used for coating glue on the lower layer 200 of the seamless quilt in the embodiment 1, and referring toFigure 6 、 Figure 7 The gluing device comprises a laying table 500 for laying the lower layer 200 and a three-dimensional glue dispenser 600 arranged on the laying table 500. The three-dimensional glue dispenser 600 is a device available in the prior art, which generally realizes horizontal plane movement through X and Y direction tracks so as to dispense glue at different positions, and realizes the lifting of the glue dispensing head through a Z direction lifter so as to be suitable for objects of different thicknesses.

[0050] The lower layer 200 is laid on the laying table 500, the distribution information and shape information of the relevant predetermined area 400 are input in advance into the control program of the three-dimensional glue dispenser 600, and the three-dimensional glue dispenser 600 controls the glue dispensing head to form dense point-shaped glue at the predetermined area 400.

[0051] In a further embodiment, when the three-dimensional glue dispenser 600 forms dense point-shaped glue at the predetermined area 400, point-shaped glue with different densities and glue amounts is formed at different positions.
