Description

Technical Field

[0001] This invention relates to the field of down lining manufacturing, specifically to vertical down structures for lining splicing, down products, and manufacturing methods. Background Technology

[0002] The inner lining of a down jacket is generally made of fabric and quilting. The quilting divides the inner lining into several horizontal down-filled areas to prevent down from falling off. However, the quilting area is a weak point in the insulation of the inner lining. If the quilting is too dense, there will be more weak areas in insulation. If the quilting is loose, there will be a lack of stable vertical connection structure between the inner and outer layers of the inner lining, which can easily lead to uneven distribution of down in the down-filled areas.

[0003] In response, application number 202311439102.9 discloses a vertical structure of a down jacket and its preparation method. It forms a vertical connection structure by setting several Z-shaped mesh fabrics between the inner lining fabric and the outer fabric, thus maintaining a stable connection between the inner lining fabric and the outer fabric. However, this method has the following shortcomings: the inner lining is filled with down after the mesh fabric is formed, which divides the inner lining into multiple down filling areas and increases the number of down filling times for each inner lining. Furthermore, due to its process of forming before filling, the mesh fabric is only suitable for replacing quilting (extending laterally along the inner lining) and cannot extend longitudinally along the inner lining to prevent lateral down leakage. Summary of the Invention

[0004] The purpose of this invention is to provide a vertical down structure for splicing inner linings, down products, and a manufacturing method, which solves the problem that existing vertical structures for inner linings cannot separate the down filling areas along the longitudinal direction.

[0005] The present invention achieves the above objectives through the following technical solutions: A vertical down-filled structure with spliced ​​inner lining includes several spliced ​​inner lining units. Each inner lining unit has several partition units inside to divide the inner lining unit into several down-filling cavities along its length. The inner lining unit surface has an opening corresponding to the partition unit, and the opening is provided with a sealing component. The dividing unit includes a dividing net folded inside the inner liner unit. One side of the dividing net is connected to the inner liner unit, and the other end is provided with at least two guide ropes extending to the opening, which are used to unfold the dividing net and connect it to the sealing assembly after filling with down.

[0006] As a preferred embodiment of the present invention, the inner liner unit is provided with a down filling port at one end and a sealing part at the other end, and a splicing adhesive layer is provided between adjacent inner liner units. By providing a splicing adhesive layer, this embodiment effectively reduces the weak insulation area caused by quilting when the inner liner units are spliced.

[0007] As a preferred embodiment of the present invention, one end of the separator is provided with a first adhesive part for adhering and fixing to the inner wall of the inner liner unit, and the other end is provided with a second adhesive part for connecting to the sealing component at the opening. By providing the second adhesive part, this embodiment enables the separator unit to be unfolded and sealed after the down filling is completed, thereby achieving the purpose of filling down first and then forming the down filling cavity, thus effectively preventing the down from moving and agglomerating laterally.

[0008] As a preferred embodiment of the present invention, the folded portion of the separator net is provided with an adhesive strip for temporary fixation, which is used to prevent the separator net from unfolding during filling. This embodiment folds the separator net and provides a temporary fixing adhesive strip at the fold. The adhesive strip does not need to be durable or have strong adhesive ability; it only needs to temporarily fix the separator net and can be detached directly after subsequent stress.

[0009] As a preferred embodiment of the present invention, the sealing assembly includes a first extension portion disposed on the outside of the opening, a second extension portion disposed on the outside of the opening, and a mesh covering the opening. The guide rope passes through the gap of the mesh to the outside of the inner liner unit, and a limiting portion is provided at the end of the guide rope. This embodiment, by specifically setting the sealing assembly, enables the opening to be sealed after the partition unit is unfolded, and at the same time fixes the partition net. The purpose of setting the mesh is to prevent down leakage during the down filling process and to help vent air during the down filling process.

[0010] As a preferred embodiment of the present invention, a first hot melt adhesive layer and a second hot melt adhesive layer are respectively provided on the opposite surfaces of the first extension and the second extension, which are used to adhere the second adhesive part between the first extension and the second extension. This embodiment uses the hot melt adhesive layer to heat-press and seal the first extension and the second extension, and connects and fixes the second adhesive part together.

[0011] As a preferred embodiment of the present invention, a first flexible magnetic part and a second flexible magnetic part are respectively provided in the second extension part and the second adhesive part. The flexible magnetic part is used to clamp the first extension part and the second extension part together with the second adhesive part by means of an external magnetic component when sealing. The flexible magnetic part is a sheet-like flexible material pre-made from iron powder and colloid. Since this solution requires hot pressing and bonding, in order to prevent damage to the down, this solution uses magnetic attraction to make the second extension part clamp the second adhesive part upward.

[0012] On the one hand, in order to apply the above-mentioned vertical down structure with spliced ​​inner lining, the present invention also proposes a down product including any of the above-mentioned vertical down structure with spliced ​​inner lining.

[0013] On the other hand, in order to produce the aforementioned vertical down structure with spliced ​​inner lining, the present invention also proposes a manufacturing method based on the aforementioned vertical down structure with spliced ​​inner lining, comprising the following steps: S1: Several inner lining units are glued and assembled, and down filling machines are used to fill the inner lining units with down, and then the down filling port is sealed. S2: Pull the second adhesive part between the first extension part and the second extension part using the guide rope; S3: The magnetic attraction component attracts the first extension and the second extension to clamp the second adhesive part, and heats and melts the first hot melt adhesive layer and the second hot melt adhesive layer, and then cuts off the guide rope.

[0014] The beneficial effects of the present invention are as follows: By folding the partition unit inside the inner liner unit, the present invention does not affect the filling of down from the filling port. Furthermore, by setting the opening and sealing component, the partition unit can be unfolded after the filling process, thereby forming several filling cavities in the horizontal direction. The sealing component makes the opening and the unfolded partition unit fixed and closed, which greatly increases the ability of the inner liner unit to prevent down leakage and clumping in the horizontal direction.

[0016] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0017] Example 1 like Figure 1-6 As shown, a vertical down structure with spliced ​​inner lining includes several spliced ​​inner lining units 1. The inner lining unit 1 is provided with several partition units 3 inside, which are used to divide the inner lining unit 1 into several down-filling cavities 102 along the length direction. The inner lining unit 1 is provided with an opening 104 corresponding to the partition unit 3, and the opening 104 is provided with a sealing component 2. The partition unit 3 includes a partition net 31 folded inside the inner liner unit 1. One side of the partition net 31 is connected to the inner liner unit 1, and the other end is provided with at least two guide ropes 35 extending to the opening 104 for unfolding the partition net 31 after filling with down and sealing it with the sealing assembly 2.

[0018] This solution folds the partition unit 3 inside the inner liner unit 1. This method does not affect the filling of down through the filling port 101. Furthermore, by setting the opening 104 and the sealing component 2, the partition unit 3 can be unfolded after the filling process, thereby forming several filling cavities 102 in the horizontal direction. The sealing component 2 shapes and seals the opening 104 and the unfolded partition unit 3, greatly increasing the ability of the inner liner unit 1 to prevent down leakage and clumping in the horizontal direction.

[0019] Specifically, during production, several inner lining units 1 are glued together, and a down filling machine is used to fill the inner lining units 1 with down, and then the down filling port is sealed; the partition net 31 is unfolded by the guide rope 35, and the opening 104 and the partition net 31 are sealed by the sealing assembly 2, and finally the guide rope 35 is cut off.

[0020] Preferably, one end of the inner liner unit 1 is provided with a down filling port 101 and the other end is provided with a sealing part 103, and a splicing adhesive layer 5 is provided between adjacent inner liner units 1. By setting the splicing adhesive layer 5, this solution can effectively reduce the weak insulation area caused by quilting when the inner liner unit 1 is spliced.

[0021] Preferably, one end of the separator 31 is provided with a first adhesive part 32 for adhering and fixing to the inner wall of the inner liner unit 1, and the other end is provided with a second adhesive part 34 for connecting to the sealing component 2 at the opening 104. By providing the second adhesive part 34, this solution enables the separator unit 3 to unfold and be sealed after the down filling is completed, thereby achieving the purpose of filling down first and then forming the down filling cavity 102, thus effectively preventing the down from moving and agglomerating laterally.

[0022] Preferably, the folded portion of the separator 31 is provided with an adhesive strip 33 for temporary fixation, which is used to prevent the separator 31 from unfolding during down filling. This solution folds the separator 31 and provides an adhesive strip 33 for temporary fixation at the fold. The adhesive strip 33 does not need to be durable or have strong adhesive ability. It only needs to temporarily fix the separator 31 and can be easily detached after subsequent stress. The adhesive strip 33 adheres to some down on both sides of the separator 31, forming a more tight down-proof structure.

[0023] Preferably, the sealing assembly 2 includes a first extension 21 disposed outside the opening 104, a second extension 22 disposed outside the opening 104, and a mesh 23 covering the opening 104. A guide rope 35 passes through the gap of the mesh 23 to the outside of the inner liner unit 1, and a limiting part 36 is provided at the end of the guide rope 35. This solution, by specifically setting the sealing assembly 2, enables the opening 104 to be sealed after the partition unit 3 is unfolded, and at the same time fixes the partition net 31. The purpose of setting the mesh 23 is to prevent down leakage during the down filling process and to help vent air during the down filling process.

[0024] Preferably, a first hot melt adhesive layer 24 and a second hot melt adhesive layer 25 are respectively provided on the opposite surfaces of the first extension 21 and the second extension 22, which are used to bond the second adhesive part 34 between the first extension 21 and the second extension 22. In this solution, by providing hot melt adhesive layers, the first extension 21 and the second extension 22 are heat-sealed and the second adhesive part 34 is connected and fixed together.

[0025] Preferably, a first flexible magnetic part 26 and a second flexible magnetic part 37 are respectively provided in the second extension 22 and the second adhesive part 34. The flexible magnetic part is used to clamp the first extension 21 and the second extension 22 with the second adhesive part 34 by means of an external magnetic component when sealing. The flexible magnetic part is a sheet-like flexible material pre-made from iron powder and colloid. Since this solution requires hot pressing and bonding, in order to prevent damage to the down, this solution uses magnetic attraction to make the second extension 21 clamp the second adhesive part 34 upward.

[0026] Detailed implementation method: First, several inner liner units 1 are spliced ​​together. Then, a down filling machine is used to fill the down filling port 101 with down. After the down filling amount is reached, the down filling port 101 is closed. Then, the guide rope 35 is pulled to break the adhesive strip 33, the partition net 31 is fully unfolded, and the second adhesive part 34 enters between the first extension part 21 and the second extension part 22. Then, the magnetic suction component 4 is used to attract the second extension part 22, the second adhesive part 34, and the first extension part 21 to stick together. Then, heating is used to melt and stick the first hot melt adhesive layer 24 and the second hot melt adhesive layer 25 together. The magnetic suction component 3 is an electromagnet that can withstand high temperature in the prior art. After the opening 104 is closed, the guide rope 35 is cut off.

[0027] On the one hand, in order to apply the above-mentioned vertical down structure with spliced ​​inner lining, the present invention also proposes a down product including any of the above-mentioned vertical down structure with spliced ​​inner lining.

[0028] On the other hand, in order to produce the aforementioned vertical down structure with spliced ​​inner lining, the present invention also proposes a manufacturing method based on the aforementioned vertical down structure with spliced ​​inner lining, comprising the following steps: S1: Adhere and assemble several inner lining units 1, fill the inner lining unit 1 with down using a down filling machine, and then seal the down filling port; S2: The second adhesive part 34 is pulled between the first extension part 21 and the second extension part 22 by the guide rope 35; S3: The magnetic component 4 attracts the first extension 21 and the second extension 22 to clamp the second adhesive part 34, and heats and melts the first hot melt adhesive layer 24 and the second hot melt adhesive layer 25, and then cuts off the guide rope 35.

[0029] The magnetic suction assembly 4 includes a negative pressure plate 41 and a high-temperature resistant magnetic heating plate 42. The negative pressure plate 41 is provided with several negative pressure holes 43. In use, the magnetic heating plate 42 covers the area of ​​the first extension 21. The negative pressure plate 41 flattens the surface fabric of the inner liner unit 1 on both sides and slightly lifts it so that the hot-pressed area is separated from the down in the inner liner unit 1 as much as possible, which can effectively reduce the damage of the hot-pressed high temperature to the down.

[0030] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
