Description

Curtain manufacturing method and curtain body Technical Field

[0001] This application relates to the field of curtain manufacturing technology, and in particular to a method for manufacturing a curtain body and the curtain body itself. Background Technology

[0002] Honeycomb blinds, also known as accordion blinds, are, as the name suggests, shaped like an accordion when pulled open, resembling a honeycomb. The biggest advantage of honeycomb blinds is that they can meet the needs of various types of family windows, whether it is a corner window, an oval arched window, a floor-to-ceiling window, a sloping roof window, or even a skylight. Honeycomb blinds can give them a gorgeous look. Their unique honeycomb structure allows air to be stored in the hollow layer, keeping the indoor temperature constant.

[0003] Honeycomb blinds generally include a curtain rod, a foldable curtain body, and a pull cord. The curtain body consists of multiple folding units connected in sequence. Each folding unit of the curtain body has a through hole. The pull cord passes through the through hole on each folding unit. By using the pull cord, the lower end of the curtain body is pulled up or lowered, so that the folding units are folded together or unfolded, thereby realizing the opening and closing of the honeycomb blind. Technical issues

[0004] Currently, honeycomb blinds generally have the following disadvantages: The curtain body of honeycomb blinds is generally formed by bonding together multiple quadrilateral or hexagonal unit curtains. This not only makes the manufacturing process complex and inefficient, but also makes it easy for the upper and lower unit curtains to deviate in position during bonding, thus affecting the structural strength, aesthetics and service life of the honeycomb blind. Technical solutions

[0005] The purpose of this application is to provide a method for manufacturing a curtain body. This method is simple, can produce multiple curtain bodies at once, and produces curtain bodies with stable and reliable structures, thereby improving the production efficiency and service life of the curtain bodies.

[0006] This application provides a method for manufacturing a curtain, including the following steps:

[0007] S1: Provide at least one fabric layer;

[0008] S2: The fabric layers are stacked along their first thickness direction to obtain a stacked body with multiple layers; and the adjacent layers in the stacked body are composited to connect the adjacent layers together.

[0009] Each of the stacked layers is provided with a plurality of first composite parts and a plurality of second composite parts. Each of the first composite parts and each of the second composite parts extends continuously along the length direction of the fabric layer, and the plurality of first composite parts and the plurality of second composite parts are alternately spaced along the first width direction of the fabric layer. Along the first thickness direction, in every three adjacent stacked layers, the plurality of first composite parts on two adjacent stacked layers are connected to each other, and the plurality of second composite parts on the other two adjacent stacked layers are connected to each other.

[0010] S3: Cut the superimposed body to obtain multiple cut bodies, which are curtain bodies.

[0011] In one possible implementation, in step S2 above, the width of the first composite portion and the width of the second composite portion are equal along the first width direction, and the spacing between each adjacent first composite portion and second composite portion is equal.

[0012] In one possible implementation, in step S2 above, the spacing between adjacent first composite parts along the first width direction is 10mm to 50mm, and the spacing between adjacent second composite parts is 10mm to 50mm.

[0013] And / or, along the first width direction, the width of the first composite portion and the width of the second composite portion are both 3mm to 10mm.

[0014] In one possible implementation, step S3 above, specifically the trimming of the superimposed body, includes:

[0015] The superimposed body is cut along a first cutting surface and a second cutting surface; wherein the first cutting surface is parallel to both the first width direction and the first thickness direction, the second cutting surface is perpendicular to the first width direction and parallel to the first thickness direction, and the second cutting surface passes through the first composite part or the second composite part.

[0016] In one possible implementation, the second cutting surface passes through the middle position of the first composite portion or the middle position of the second composite portion along the first width direction.

[0017] In one feasible approach, the number of the second cutting surfaces is multiple;

[0018] Two adjacent second cut surfaces pass through an adjacent column of the first composite section and a column of the second composite section, respectively, so that the curtain body is formed as a pleated curtain body;

[0019] Alternatively, two adjacent second cut surfaces may pass through two different columns of the first composite section, or two different columns of the second composite section, or a non-adjacent column of the first composite section and a column of the second composite section, so that the curtain is formed as a honeycomb curtain.

[0020] In one possible implementation, in step S2 above, along the first thickness direction, in every three adjacent stacks, a plurality of the first composite parts on two adjacent stacks are connected by ultrasonic composite connection or thermo-press composite connection, and a plurality of the second composite parts on the other two adjacent stacks are connected by ultrasonic composite connection or thermo-press composite connection.

[0021] In one possible implementation, in step S2 above, along the first thickness direction, in every three adjacent stacks, the plurality of first composite portions on two adjacent stacks are bonded by a plurality of first adhesive layers, and the plurality of second composite portions on the other two adjacent stacks are bonded by a plurality of second adhesive layers.

[0022] In one possible implementation, in step S1 above, at least one of the fabric layers includes a first fabric layer and a second fabric layer, wherein the first fabric layer and the second fabric layer are disposed opposite each other.

[0023] The above S2 step specifically includes:

[0024] A plurality of first adhesive layers and a plurality of second adhesive layers are disposed on the first fabric layer and / or the second fabric layer; wherein, the first adhesive layer is disposed on the lower surface of the first fabric layer and / or the upper surface of the second fabric layer, and the second adhesive layer is disposed on the upper surface of the first fabric layer and / or the lower surface of the second fabric layer; the plurality of first adhesive layers correspond to a plurality of first composite parts, and the plurality of second adhesive layers correspond to a plurality of second composite parts; each first adhesive layer and each second adhesive layer extends continuously along the length direction, and the plurality of first adhesive layers and the plurality of second adhesive layers are alternately spaced along the first width direction;

[0025] The first fabric layer and the second fabric layer are combined such that the first fabric layer and the second fabric layer are bonded together by a plurality of first adhesive layers, thereby bonding a plurality of first composite parts on adjacent stacks by a plurality of first adhesive layers to form an adhesive body;

[0026] The adhesive is wound up to obtain the stacked body with a cylindrical structure, the stacked body including a plurality of winding loops; during the winding process, adjacent winding loops in the stacked body are bonded together by a plurality of second adhesive layers, thereby bonding a plurality of second composite parts on adjacent stacked layers by a plurality of second adhesive layers.

[0027] This application also provides a curtain having a height direction and a second thickness direction that are perpendicular to each other. The curtain includes a plurality of slats arranged sequentially along the height direction. Each slat is provided with a plurality of first joints and a plurality of second joints, and the plurality of first joints and the plurality of second joints are arranged alternately and at intervals along the second thickness direction.

[0028] Along the height direction, the plurality of first joint portions on each pair of adjacent curtain slats correspond one-to-one, and the plurality of second joint portions on each pair of adjacent curtain slats correspond one-to-one;

[0029] Along the height direction, in every three adjacent slats, multiple first joints on two adjacent slats are connected one-to-one, and multiple second joints on the other two adjacent slats are connected one-to-one, so that the curtain body forms a multi-layer honeycomb structure; when the curtain body is unfolded, a cavity is formed between each of the adjacent two slats at each adjacent joint.

[0030] In one possible implementation, the curtain body further has a second width direction, which is perpendicular to each other as is the height direction and the second thickness direction; the first joint and the second joint both extend continuously along the second width direction.

[0031] In one feasible manner, in each of the slats, the number of one of the first joint and the second joint is not less than three, and the number of the other is not less than two.

[0032] In one possible implementation, the widths of the corresponding first joint portions on each pair of adjacent slats are equal, and the widths of the corresponding second joint portions on each pair of adjacent slats are equal.

[0033] In one feasible embodiment, the width of both the first joint and the width of the second joint are 3mm to 10mm along the second thickness direction.

[0034] In one possible implementation, when the curtain is folded, the spacing between each adjacent first joint and second joint in each slat is equal, and the spacing between each adjacent first joint and second joint is greater than the width of the first joint and the width of the second joint.

[0035] In one feasible manner, when the curtain is folded, the spacing between adjacent first joints along the second thickness direction is 10mm to 50mm, and the spacing between adjacent second joints is 10mm to 50mm.

[0036] In one feasible manner, along the second thickness direction, in every three adjacent slats, the plurality of first bonding portions on two adjacent slats are bonded one-to-one by a plurality of first adhesive layers, and the plurality of second bonding portions on the other two adjacent slats are bonded one-to-one by a plurality of second adhesive layers.

[0037] In one feasible manner, along the second thickness direction, in every three adjacent slats, a plurality of first joints on two adjacent slats are connected one-to-one by ultrasonic bonding, and a plurality of second joints on the other two adjacent slats are connected one-to-one by ultrasonic bonding.

[0038] In one feasible manner, along the second thickness direction, in every three adjacent slats, a plurality of first joints on two adjacent slats are connected one-to-one by thermoforming, and a plurality of second joints on the other two adjacent slats are connected one-to-one by thermoforming. Beneficial effects

[0039] The method for manufacturing a curtain provided in this application involves stacking fabric layers along their first thickness direction to obtain a stacked body with multiple layers; and performing a composite process between adjacent layers in the stacked body, such that in every three adjacent layers, multiple first composite parts on two adjacent layers are connected to each other, and multiple second composite parts on the other two adjacent layers are connected to each other, thus giving the stacked body multiple curtain structures; through a subsequent cutting step, the stacked body can be divided into multiple cut bodies, thereby obtaining multiple curtains.

[0040] The manufacturing method of this curtain is not only simple and streamlined, which helps to reduce production costs, but also produces a stable and reliable curtain structure. Furthermore, there will be no misalignment or positional deviation between adjacent folding units in the curtain, which improves the production efficiency, service life, and aesthetics of the curtain.

[0069] [First Embodiment]

[0070] As shown in Figures 1 to 7, the first embodiment of this application provides a method for manufacturing a curtain, including the following steps:

[0071] S1: Provide at least one fabric layer 1; the fabric layer 1 is a rectangular sheet structure, and the fabric layer 1 has a length direction L, a first width direction W and a first thickness direction that are perpendicular to each other;

[0072] S2: The fabric layer 1 is stacked along its first thickness direction H to obtain a stacked body 6 with multiple stacked layers 10, and the multiple stacked layers 10 are stacked sequentially along the first thickness direction H; and the adjacent stacked layers 10 in the stacked body 6 are composited to connect the adjacent stacked layers 10 together (as shown in Figure 5g, adjacent stacked layers 10 refer to two stacked layers 10 that are stacked adjacently along the first thickness direction H).

[0073] Each layer 10 is provided with multiple first composite parts 101 and multiple second composite parts 102, which are integral with the layer 10 (fabric layer 1). Each first composite part 101 and each second composite part 102 extends continuously along the length direction L of the fabric layer 1 (i.e., both the first composite part 101 and the second composite part 102 are elongated structures extending along the length direction L), and the multiple first composite parts 101 and the multiple second composite parts 102 are alternately arranged along the first width direction W of the fabric layer 1 (i.e., the first composite parts 101 and the second composite parts 102 are staggered along the first width direction W). The multiple first composite parts 101 on each pair of adjacent layers 10 correspond one-to-one, and the multiple second composite parts 102 on each pair of adjacent layers 10 correspond one-to-one.

[0074] Along the first thickness direction H, in every three adjacent stacks 10, the plurality of first composite parts 101 on two adjacent stacks 10 are connected to each other (i.e., the plurality of first composite parts 101 on one stack 10 are connected one-to-one with the plurality of first composite parts 101 on the other stack 10), and the plurality of second composite parts 102 on the other two adjacent stacks 10 are connected to each other (i.e., the plurality of second composite parts 102 on one stack 10 are connected one-to-one with the plurality of second composite parts 102 on the other stack 10); while other parts of adjacent stacks 10 are not connected to each other.

[0075] S3: Cut the superimposed body 6 to obtain multiple cut bodies 62, and the cut bodies 62 are curtain bodies 7 (multiple cut bodies 62 are multiple curtain bodies 7); at the same time, the curtain body 7 can be unfolded and folded.

[0076] The curtain manufacturing method provided in this application involves stacking fabric layers 1 along their first thickness direction H to obtain a stacked body 6 with multiple layers 10; and performing a composite process between adjacent layers 10 in the stacked body 6, such that in every three adjacent layers 10, multiple first composite parts 101 on two adjacent layers 10 are interconnected, and multiple second composite parts 102 on the other two adjacent layers 10 are interconnected, thus giving the stacked body 6 multiple curtain structures; through a subsequent cutting step, the stacked body 6 can be divided into multiple cut bodies 62, thereby obtaining multiple curtains 7. This curtain manufacturing method is not only simple in process and simplifies the manufacturing process, which helps to reduce production costs, but also produces curtains 7 with stable and reliable structures, and there is no misalignment or positional deviation between adjacent folding units in the curtain 7, improving the production efficiency, service life, and aesthetics of the curtain 7.

[0077] In step S2 above, in this embodiment, the fabric layer 1 is stacked along its first thickness direction H while the adjacent layers 10 in the stacked body 6 are composited. Of course, in other embodiments, the fabric layer 1 can be stacked along its first thickness direction H first, and then the adjacent layers 10 in the stacked body 6 can be composited.

[0078] In one embodiment, the number of the first composite part 101 and each of the second composite parts 102 is greater than or equal to three.

[0079] As shown in Figures 1 to 7, in one embodiment, in step S2 above, adjacent layers 10 in the stacked body 6 are bonded together by adhesive layers. Specifically, along the first thickness direction H, in every three adjacent layers 10, multiple first composite parts 101 on two adjacent layers 10 are bonded together by multiple first adhesive layers 3 (i.e., multiple first composite parts 101 on one layer 10 are bonded to multiple first composite parts 101 on another layer 10 in a one-to-one correspondence with each other by multiple first adhesive layers 3), and multiple second composite parts 102 on two other adjacent layers 10 are bonded together by multiple second adhesive layers 4 (i.e., multiple second composite parts 102 on one layer 10 are bonded to multiple second composite parts 102 on another layer 10 in a one-to-one correspondence with each other by multiple second adhesive layers 4).

[0080] As shown in Figures 1 to 7, in one embodiment, in step S1 above, at least one fabric layer 1 includes a first fabric layer 11 and a second fabric layer 12, which are arranged vertically and horizontally with a gap between them, and the first fabric layer 11 is located above the second fabric layer 12; wherein, both the first fabric layer 11 and the second fabric layer 12 are rectangular sheet structures, and the first fabric layer 11 and the second fabric layer 12 have the same shape and length and width dimensions (the thickness and color can be the same or different; preferably, the thickness and color of both are the same).

[0081] The above S2 step specifically includes:

[0082] A plurality of first adhesive layers 3 and a plurality of second adhesive layers 4 are disposed on the first fabric layer 11 and / or the second fabric layer 12; wherein, the first adhesive layer 3 is disposed on the lower surface of the first fabric layer 11 and / or the upper surface of the second fabric layer 12 (that is, the first adhesive layer 3 is disposed on the surfaces of the first fabric layer 11 and the second fabric layer 12 that are close to each other), and the second adhesive layer 4 is disposed on the upper surface of the first fabric layer 11 and / or the lower surface of the second fabric layer 12 (that is, the second adhesive layer 4 is disposed on the surfaces of the first fabric layer 11 and the second fabric layer 12 that are far from each other). Multiple first adhesive layers 3 correspond to multiple first composite parts 101 (one-to-one correspondence), and multiple second adhesive layers 4 correspond to multiple second composite parts 102 (one-to-one correspondence); each first adhesive layer 3 and each second adhesive layer 4 extend continuously along the length direction L (i.e., both the first adhesive layer 3 and the second adhesive layer 4 are long strip structures extending along the length direction L), and the multiple first adhesive layers 3 and the multiple second adhesive layers 4 are alternately spaced along the first width direction W (i.e., along the first width direction W, the first adhesive layer 3 and the second adhesive layer 4 are staggered).

[0083] The first fabric layer 11 and the second fabric layer 12 are combined so that the first fabric layer 11 and the second fabric layer 12 are bonded together by a plurality of first adhesive layers 3, thereby bonding a plurality of first composite parts 101 on adjacent stacks 10 by a plurality of first adhesive layers 3 to form an adhesive body 5 (since the first adhesive layers 3 are disposed on the surfaces of the first fabric layer 11 and the second fabric layer 12 that are close to each other, the lower surface of the first fabric layer 11 and the upper surface of the second fabric layer 12 can be bonded together by the first adhesive layers 3 when they come into contact).

[0084] The adhesive body 5 is wound up to obtain a cylindrical stacked body 6, which includes multiple winding loops (not labeled in the figure). During the winding process, adjacent winding loops in the stacked body 6 are bonded together by multiple second adhesive layers 4, thereby bonding multiple second composite parts 102 on adjacent stacked layers 10 together by multiple second adhesive layers 4.

[0085] Specifically, during the winding process, the adhesive 5 is wound around in circles, forming multiple winding loops arranged sequentially from the inside out (each winding loop has two layers 10). At the same time, since the second adhesive layer 4 is disposed on the surfaces of the first fabric layer 11 and the second fabric layer 12 that are far apart from each other, adjacent winding loops are bonded together by multiple second adhesive layers 4 during the winding process. As shown in Figure 5g, each adjacent layer 10 is either bonded together by multiple first adhesive layers 3 or by multiple second adhesive layers 4, thus obtaining a cylindrical stacked body 6.

[0086] In this embodiment, the aforementioned "overlaying process of fabric layer 1 along its first thickness direction H" actually involves winding fabric layer 1 along its length direction L to form a stacked body 6 with multiple layers 10 (of course, in other embodiments, multiple layers 10 can also be formed in other ways, such as folding fabric layer 1 back and forth multiple times along its length direction L). The aforementioned "composite processing between adjacent layers 10 in the stacked body 6" actually involves bonding adjacent layers 10 in the stacked body 6, thereby bonding adjacent layers 10 together with an adhesive layer.

[0087] As shown in Figures 1 to 5c and Figure 7, in one embodiment, the first adhesive layer 3 is disposed on the lower surface of the first fabric layer 11, and the second adhesive layer 4 is disposed on the upper surface of the first fabric layer 11, that is, the first adhesive layer 3 and the second adhesive layer 4 are simultaneously disposed on the first fabric layer 11. As shown in Figure 8, in another embodiment, the first adhesive layer 3 is disposed on the upper surface of the second fabric layer 12, and the second adhesive layer 4 is disposed on the upper surface of the first fabric layer 11. As shown in Figure 9, in another embodiment, the first adhesive layer 3 is simultaneously disposed on the lower surface of the first fabric layer 11 and the upper surface of the second fabric layer 12, and the second adhesive layer 4 is simultaneously disposed on the upper surface of the first fabric layer 11 and the lower surface of the second fabric layer 12.

[0088] Of course, in other embodiments, the first adhesive layer 3 and the second adhesive layer 4 can also be configured in other ways, such as both the first adhesive layer 3 and the second adhesive layer 4 being disposed on the second fabric layer 12, as long as at least one of the lower surface of the first fabric layer 11 and the upper surface of the second fabric layer 12 is provided with the first adhesive layer 3, at least one of the upper surface of the first fabric layer 11 and the lower surface of the second fabric layer 12 is provided with the second adhesive layer 4, and the first adhesive layer 3 and the second adhesive layer 4 are arranged alternately.

[0089] In one embodiment, the number of the first adhesive layer 3 and the second adhesive layer 4 is greater than or equal to three.

[0090] As shown in Figures 1 and 5a to 5c, in one embodiment, in step S2 above, a plurality of first adhesive layers 3 and a plurality of second adhesive layers 4 can be first provided on the first fabric layer 11 and / or the second fabric layer 12, and then the first fabric layer 11 and the second fabric layer 12 can be bonded together.

[0091] Of course, in other embodiments, multiple first adhesive layers 3 can be first applied to the first fabric layer 11 and / or the second fabric layer 12, then the first fabric layer 11 and the second fabric layer 12 can be bonded together, and then multiple second adhesive layers 4 can be applied to the first fabric layer 11 and / or the second fabric layer 12. It is only necessary to ensure that the application of adhesive to the first adhesive layer 3 occurs before the bonding step of the first fabric layer 11 and the second fabric layer 12, and that the application of adhesive to the second adhesive layer 4 occurs before the winding step.

[0092] Furthermore, the application steps of the first adhesive layer 3 and the second adhesive layer 4 do not need to be distinguished in terms of order. The first adhesive layer 3 can be applied first and then the second adhesive layer 4 can be applied, or the second adhesive layer 4 can be applied first and then the first adhesive layer 3 can be applied, or the first adhesive layer 3 and the second adhesive layer 4 can be applied simultaneously.

[0093] As shown in Figures 1 to 5c, in one embodiment, in step S2 above, a plurality of first adhesive layers 3 and a plurality of second adhesive layers 4 are formed by rolling a first adhesive roller 821 and a second adhesive roller 822 onto a first fabric layer 11 and / or a second fabric layer 12, respectively.

[0094] The first pressure roller 821 includes a first roller body 8211 and a plurality of first annular protrusions 8212 protruding from the outer surface of the first roller body 8211. The first roller body 8211 is cylindrical, and the first annular protrusions 8212 are annular structures that surround the first roller body 8211 in a circumferential direction. The plurality of first annular protrusions 8212 are spaced apart along the first width direction W. Each of the plurality of first annular protrusions 8212 is coated with adhesive, and the plurality of first adhesive layers 3 are formed by rolling the adhesive onto the first fabric layer 11 and / or the second fabric layer 12 by the plurality of first annular protrusions 8212.

[0095] The second pressure roller 822 includes a second roller body 8221 and a plurality of second annular protrusions 8222 protruding from the outer surface of the second roller body 8221. The second roller body 8221 is cylindrical, and the second annular protrusions 8222 are annular structures that surround the second roller body 8221 in a circumferential direction. The plurality of second annular protrusions 8222 are spaced apart along the first width direction W. Each of the plurality of second annular protrusions 8222 is coated with adhesive. The plurality of second adhesive layers 4 are formed by rolling the adhesive onto the first fabric layer 11 and / or the second fabric layer 12 by the plurality of second annular protrusions 8222.

[0096] Specifically, in this embodiment, a plurality of first adhesive layers 3 and a plurality of second adhesive layers 4 are formed by roller application of adhesive onto the first fabric layer 11 and / or the second fabric layer 12 using an adhesive application device 82. The adhesive application device 82 includes the aforementioned first pressure roller 821, second pressure roller 822, guide roller 823, and adhesive reservoir 824. The first pressure roller 821, second pressure roller 822, and guide roller 823 are all rotatable. The adhesive reservoir 824 stores liquid adhesive (i.e., liquid adhesive), and the guide roller 823 is partially immersed in the adhesive in the adhesive reservoir 824. When the guide roller 823 rotates, it can transfer the adhesive from the adhesive reservoir 824 to its surface. A plurality of first annular protrusions 8212 correspond one-to-one with a plurality of first adhesive layers 3, and a plurality of second annular protrusions 8222 correspond one-to-one with a plurality of second adhesive layers 4.

[0097] During the application of adhesive, multiple first annular protrusions 8212 on the first pressure roller 821 contact the lower surface of the first fabric layer 11 and the outer surface of the guide roller 823, respectively. Multiple second annular protrusions 8222 on the second pressure roller 822 contact the upper surface of the first fabric layer 11 and the outer surface of the guide roller 823, respectively (the guide roller 823 in contact with the second pressure roller 822 is not shown in Figure 4). At the same time, the first pressure roller 821, the second pressure roller 822 and the guide roller 823 all rotate, and the first fabric layer 11 flows backward. After the multiple first annular protrusions 8212 on the first pressure roller 821 come into contact with the outer surface of the guide roller 823, the adhesive on the surface of the guide roller 823 is transferred onto the multiple first annular protrusions 8212. After the multiple first annular protrusions 8212 come into contact with the lower surface of the first fabric layer 11, the adhesive on the multiple first annular protrusions 8212 is pressed (rolled) onto the lower surface of the first fabric layer 11, thereby forming multiple continuous first adhesive layers 3. After the multiple second annular protrusions 8222 on the second pressure roller 822 come into contact with the outer surface of the guide roller 823, the adhesive on the surface of the guide roller 823 is transferred onto the multiple second annular protrusions 8222. After the multiple second annular protrusions 8222 come into contact with the upper surface of the first fabric layer 11, the adhesive on the multiple second annular protrusions 8222 is pressed (rolled) onto the upper surface of the first fabric layer 11, thereby forming multiple continuous second adhesive layers 4. In this embodiment, the method of first applying adhesive to the guide roller 823 and then applying the adhesive to the first annular protrusion 8212 / second annular protrusion 8222 is adopted to avoid the first annular protrusion 8212 / second annular protrusion 8222 directly contacting the adhesive in the adhesive storage tank 824, which could easily lead to problems such as adhesive dripping and uneven distribution on the first annular protrusion 8212 / second annular protrusion 8222, thus improving the uniformity of adhesive application. The accompanying drawings of this embodiment show that the first pressure roller 821 has four first annular protrusions 8212 and the second pressure roller 822 has three second annular protrusions 8222, thereby forming four first adhesive layers 3 and three second adhesive layers 4 on the first fabric layer 11, respectively. In reality, the number of first annular protrusions 8212 and second annular protrusions 8222 is more, generally more than ten, resulting in more first adhesive layers 3 and second adhesive layers 4, generally more than ten.

[0098] Of course, in other embodiments, a plurality of first adhesive layers 3 and a plurality of second adhesive layers 4 may be provided on the first fabric layer 11 and / or the second fabric layer 12 by other means or other structural types of the adhesive application device 82.

[0099] As shown in Figures 1 and 5b to 5c, in one embodiment, in step S2 above, the first fabric layer 11 and the second fabric layer 12 are bonded together by a plurality of first adhesive layers 3, specifically including:

[0100] The first fabric layer 11 and the second fabric layer 12 are rolled using the roller pressing assembly 83, so that the lower surface of the first fabric layer 11 comes into contact with the upper surface of the second fabric layer 12, and the lower surface of the first fabric layer 11 and the upper surface of the second fabric layer 12 are bonded together by multiple first adhesive layers 3.

[0101] Specifically, in this embodiment, the roller pressing assembly 83 includes an upper roller (not labeled) and a lower roller arranged opposite to each other, with the upper roller located above the lower roller and the upper and lower rollers rotating in opposite directions. As the first fabric layer 11 and the second fabric layer 12 flow backward, they pass between the upper and lower rollers. The upper and lower rollers apply a certain pressure to the first fabric layer 11 and the second fabric layer 12, causing the lower surface of the first fabric layer 11 to contact the upper surface of the second fabric layer 12 and bond them together through multiple first adhesive layers 3, forming an adhesive body 5. Of course, in other embodiments, the first fabric layer 11 and the second fabric layer 12 can also be bonded using other methods or devices.

[0102] As shown in Figures 1 and 5c to 5d, in one embodiment, step S2 specifically involves using a winding device 84 to wind up the adhesive body 5. During winding, the winding device 84 rotates (it can rotate clockwise or counterclockwise), and the adhesive body 5 is wound sequentially along the length direction L onto the winding device 84 to form multiple winding loops. These winding loops are bonded together by multiple second adhesive layers 4, thus obtaining a cylindrical stacked body 6. In this embodiment, the winding device 84 is a cylindrical structure (it can be a hollow cylinder or a solid cylinder), thereby forming a cylindrical structure (similar to a toilet paper roll). Of course, in other embodiments, the winding device 84 can also be of other shapes, such as a polygonal prism, in which case the stacked body 6 forms a polygonal cylindrical structure (for example, if the winding device 84 is a hexagonal prism, the stacked body 6 forms a hexagonal cylindrical structure). After winding is complete, the stacked body 6 is removed from the winding device 84.

[0103] As another implementation, in step S2 above, adjacent layers 10 in the stack 6 are connected by ultrasonic bonding. Specifically, an ultrasonic bonding machine can be used to connect adjacent layers 10 together. Specifically, along the first thickness direction H, in every three adjacent layers 10, multiple first composite parts 101 on two adjacent layers 10 are connected by ultrasonic bonding (i.e., multiple first composite parts 101 on one layer 10 are connected one-to-one with multiple first composite parts 101 on another layer 10 by ultrasonic bonding), and multiple second composite parts 102 on the other two adjacent layers 10 are connected by ultrasonic bonding (i.e., multiple second composite parts 102 on one layer 10 are connected one-to-one with multiple second composite parts 102 on another layer 10 by ultrasonic bonding).

[0104] In another implementation, in step S2 above, adjacent layers 10 in the stack 6 are joined by hot-press bonding. Specifically, a hot press can be used to join adjacent layers 10 together. Specifically, along the first thickness direction H, in every three adjacent layers 10, multiple first composite parts 101 on two adjacent layers 10 are joined by hot-press bonding (i.e., multiple first composite parts 101 on one layer 10 are connected one-to-one with multiple first composite parts 101 on another layer 10 by hot-press bonding), and multiple second composite parts 102 on the other two adjacent layers 10 are joined by hot-press bonding (i.e., multiple second composite parts 102 on one layer 10 are connected one-to-one with multiple second composite parts 102 on another layer 10 by hot-press bonding).

[0105] As shown in Figures 5e to 5j, in one embodiment, the above-mentioned step S3 involves cutting the superimposed body 6, specifically including:

[0106] The stacked body 6 is cut along the first cutting surface M and the second cutting surface N; wherein, the first cutting surface M is parallel to both the first width direction W and the first thickness direction H (in this embodiment, that is, the first cutting surface M is perpendicular to the end face 60 of the cylindrical stacked body 6), and the second cutting surface N is perpendicular to the first width direction W and parallel to the first thickness direction H (in this embodiment, that is, the second cutting surface N is parallel to the end face 60 of the cylindrical stacked body 6), that is, the first cutting surface M is perpendicular to the second cutting surface N, and each second cutting surface N passes through the first composite part 101 or the second composite part 102 (in this embodiment, that is, each second cutting surface N passes through the first adhesive layer 3 or the second adhesive layer 4).

[0107] As shown in Figures 5e to 6b, the position of the first cutting surface M determines the final width a of a single curtain 7, the position of the second cutting surface N determines the final thickness b and shape of a single curtain 7, and the number of layers 10 in the superimposed body 6 (that is, the number of turns of the adhesive body 5) determines the height c of a single curtain 7 after unfolding.

[0108] The number of first cutting surfaces M and second cutting surfaces N is generally multiple. Multiple first cutting surfaces M are spaced apart, and multiple second cutting surfaces N are spaced apart, so that multiple cut bodies 62 can be obtained after cutting, and thus multiple curtain bodies 7 can be obtained at one time.

[0109] As shown in Figures 5g and 5h, in one embodiment, during cutting, along the first width direction W, each second cutting surface N passes through the middle position of the first composite part 101 or the middle position of the second composite part 102 (that is, each second cutting surface N passes through the middle position of the first adhesive layer 3 or the middle position of the second adhesive layer 4). This allows the first composite part 101 or the second composite part 102 to be evenly distributed to the two curtains 7 on both sides of the second cutting surface N, ensuring that the shape and size of the two curtains 7 are consistent and that both curtains 7 have good structural strength. At the same time, since the second cutting surface N needs to pass through the first composite part 101 or the second composite part 102, the first composite part 101 and the second composite part 102 need to have sufficient width to ensure that the adjacent layers 10 (that is, the adjacent first fabric layer 11 and the second fabric layer 12) have sufficient connection area and connection strength at the cut.

[0110] As shown in Figures 5e to 5j, as one implementation method, the specific cutting steps of the superimposed body 6 can be as follows:

[0111] (1) As shown in Figures 5e and 5f, the superimposed body 6 is first cut along a certain first cutting surface M so that the superimposed body 6 can be unfolded from a cylindrical structure to a roughly rectangular structure after cutting.

[0112] (2) As shown in Figures 5f to 5h, the superimposed body 6 is cut along multiple intervals of the first cutting surface M to obtain multiple intermediate bodies 61.

[0113] (3) As shown in Figures 5g to 5j, multiple intermediate bodies 61 are cut along multiple intervals of the second cutting surface N to obtain multiple cut bodies 62.

[0114] The order of steps (2) and (3) can be interchanged, or steps (2) and (3) can be performed simultaneously.

[0115] The above is just an example illustrating one cutting method; of course, in other embodiments, other methods and steps can also be used to cut the superimposed body 6.

[0116] As shown in Figures 5i to 6b, in one embodiment, when unfolding the curtain 7, simply pull the upper end of the curtain 7, allowing it to hang naturally downwards. The curtain 7 will unfold under its own weight (or you can pull the upper and lower ends of the curtain 7 and apply force upwards and downwards respectively to unfold it). The curtain 7 has multiple folding units (not labeled in the figures), each roughly rhomboid in shape, and these units are connected sequentially. During unfolding, the unconnected portions of adjacent first fabric layers 11 and second fabric layers 12 (i.e., adjacent layers 10) in the curtain 7 will separate, forming cavities 700; that is, cavities 700 are formed in each folding unit. The connecting portions of the first fabric layers 11 and second fabric layers 12 in the curtain 7 will form the folded edges of the folding units and the connecting portions of two adjacent folding units.

[0117] As shown in Figures 5g to 6b, in one embodiment, in step S4 above, there are multiple second cutting surfaces N; two adjacent second cutting surfaces N pass through two different columns of first composite parts 101 (as shown in Figure 5g, the first composite parts 101 located on the same vertical line along the first thickness direction H constitute one column. That is, among two adjacent second cutting surfaces N, one second cutting surface N passes through one column of first composite parts 101, and the other second cutting surface N passes through another column of first composite parts 101. These two columns of first composite parts 101 may be adjacent or not adjacent), that is, two adjacent second cutting surfaces N pass through two different columns of first adhesive layers 3, so that the curtain 7 is formed as a honeycomb curtain 7A. Alternatively, two adjacent second cutting surfaces N may also pass through two different columns of second composite parts 102 (the second composite parts 102 located on the same vertical line along the first thickness direction H constitute one column), that is, two adjacent second cutting surfaces N pass through two different columns of second adhesive layers 4, which can also form the curtain 7 as a honeycomb curtain 7A. Alternatively, as shown in Figures 12a to 12c, two adjacent second cutting surfaces N can also pass through a non-adjacent column of first composite parts 101 and a non-adjacent column of second composite parts 102, that is, two adjacent second cutting surfaces N can pass through a non-adjacent column of first adhesive layer 3 and a non-adjacent column of second adhesive layer 4, which can also form the curtain 7 into a honeycomb curtain 7A.

[0118] Meanwhile, as shown in Figures 5g to 6b, in this embodiment, two adjacent second cutting surfaces N pass through two adjacent columns of first composite parts 101, that is, two adjacent second cutting surfaces N pass through two adjacent columns of first adhesive layers 3, and the curtain 7 is formed as a single-layer honeycomb curtain structure (i.e., there is only one cavity 700 along the first thickness direction of the curtain 7). Of course, when two adjacent second cutting surfaces N pass through two adjacent columns of second composite parts 102, that is, when two adjacent second cutting surfaces N pass through two adjacent columns of second adhesive layers 4, the curtain 7 can also be formed as a single-layer honeycomb curtain structure.

[0119] As shown in Figures 12a to 12c, in another embodiment, two adjacent second cutting surfaces N pass through a non-adjacent column of first composite parts 101 and a column of second composite parts 102, respectively. That is, two adjacent second cutting surfaces N pass through a non-adjacent column of first adhesive layer 3 and a column of second adhesive layer 4, respectively. The curtain body 7 is formed as a multi-layer honeycomb curtain structure (that is, a multi-layer cavity 700 is formed along the first thickness direction of the curtain body 7, and two cavities 700 are shown in the figure).

[0120] As shown in Figures 11a to 11c, in another embodiment, two adjacent second cut surfaces N pass through two non-adjacent rows of second composite sections 102, that is, two adjacent second cut surfaces N pass through two non-adjacent rows of second adhesive layers 4, and the curtain 7 is formed as a multi-layer honeycomb curtain structure (the figure shows three layers of cavities 700). Of course, when two adjacent second cut surfaces N pass through two non-adjacent rows of first composite sections 101, that is, when two adjacent second cut surfaces N pass through two non-adjacent rows of first adhesive layers 3, the curtain 7 can also be formed as a multi-layer honeycomb curtain structure.

[0121] As shown in Figures 10a to 10c, in another embodiment, two adjacent second cutting surfaces N pass through an adjacent first composite section 101 and a second composite section 102, respectively. That is, two adjacent second cutting surfaces N pass through an adjacent first adhesive layer 3 and a second adhesive layer 4, respectively. At this time, there is only one connection between the upper and lower adjacent stacked layers 10 (that is, the upper and lower adjacent first fabric layer 11 and second fabric layer 12) in the cutting body 62, so that the curtain 7 is formed as a pleated curtain 7B (the pleated curtain 7B includes multiple folding units with a roughly "<" shaped structure, and no cavity is formed in the folding unit). Meanwhile, since the first composite part 101 and the second composite part 102 have a certain width, the connecting parts of the adjacent stacked layers 10 also have a certain width. At this time, holes can be punched at the folded edge position of the pleated curtain body 7B (that is, at the connecting part of the adjacent stacked layers 10), so that the pull rope 7C passes through the holes at each folded edge position to realize the folding of the pleated curtain body 7B. Therefore, there is no need to punch holes in the folding unit of the pleated curtain body 7B, which can improve the aesthetics of the pleated curtain body 7B.

[0122] As shown in Figure 7, in one embodiment, in step S2 above, along the first width direction W, the width A1 of the first composite part 101 and the width A2 of the second composite part 102 are equal, and the distance A3 between each adjacent first composite part 101 and second composite part 102 is equal. That is, the multiple first composite parts 101 and multiple second composite parts 102 are arranged alternately at equal intervals, thereby ensuring the structural consistency of each curtain 7 and facilitating production. Specifically, in this embodiment, the width of the first adhesive layer 3 is equal to the width A1 of the first composite part 101, and the width of the second adhesive layer 4 is equal to the width A2 of the second composite part 102. That is, the width of the first adhesive layer 3 and the width of the second adhesive layer 4 are equal, and the distance between each adjacent first adhesive layer 3 and second adhesive layer 4 is equal. That is, the multiple first adhesive layers 3 and multiple second adhesive layers 4 are arranged alternately at equal intervals.

[0123] As shown in Figure 7, in one embodiment, along the first width direction W, the width A1 of the first composite portion 101 and the width A2 of the second composite portion 102 are both 3mm to 10mm. The width of the first adhesive layer 3 and the width of the second adhesive layer 4 are both 3mm to 10mm.

[0124] As shown in Figure 7, in one embodiment, in step S2 above, along the first width direction W, the spacing A4 between adjacent first composite parts 101 is 10mm to 50mm, and the spacing A5 between adjacent second composite parts 102 is 10mm to 50mm. The spacing A4 between adjacent first composite parts 101 is equal to the spacing A5 between adjacent second composite parts 102. The spacing between adjacent first adhesive layers 3 is 10mm to 50mm, and the spacing between adjacent second adhesive layers 4 is 10mm to 50mm; the spacing between adjacent first adhesive layers 3 is equal to the spacing between adjacent second adhesive layers 4.

[0125] As shown in Figure 7, in one embodiment, in step S2 above, along the first width direction W, at least one edge of the laminate 10 (fabric layer 1) is provided with a first composite portion 101 and / or a second composite portion 102; preferably, the laminate 10 (fabric layer 1) is provided with the first composite portion 101 and / or the second composite portion 102 at opposite edges, so that the entire (or almost the entire) fabric layer 1 can be cut to form the curtain 7, reducing waste and improving the utilization rate of the fabric.

[0126] Specifically, in this embodiment, in step S2 above, along the first width direction W, at least one edge of the first fabric layer 11 and / or at least one edge of the second fabric layer 12 are provided with a first adhesive layer 3 and / or a second adhesive layer 4; preferably, the first fabric layer 11 and / or the second fabric layer 12 are provided with the first adhesive layer 3 and / or the second adhesive layer 4 at opposite edges, so that the entire (or almost the entire) first fabric layer 11 and the second fabric layer 12 can be cut to form a curtain 7, thereby improving the utilization rate of the fabric.

[0127] This application embodiment also provides a curtain 7, which is manufactured using the curtain manufacturing method described above.

[0128] As shown in Figures 1 to 6b, in one embodiment, the curtain 7 described above can be manufactured using a curtain manufacturing equipment 8. The curtain manufacturing equipment 8 includes an unwinding device 81, an adhesive application device 82, a roller pressing assembly 83, a winding device 84, and a cutting device (not shown). The unwinding device 81 includes a first unwinding shaft (not labeled) for unwinding the first fabric layer 11 and a second unwinding shaft (not labeled) for unwinding the second fabric layer 12. The specific manufacturing steps for the curtain 7 can be as follows:

[0129] (1) As shown in Figure 1 and Figure 5a, the first fabric layer roll and the second fabric layer roll are placed on the first unwinding shaft and the second unwinding shaft respectively. The first unwinding shaft and the second unwinding shaft rotate to make the first fabric layer 11 and the second fabric layer 12 flow backward.

[0130] (2) As shown in Figure 1 and Figure 5b, multiple first adhesive layers 3 and multiple second adhesive layers 4 are formed by rolling and coating on the first fabric layer 11 and / or the second fabric layer 12 using the adhesive coating device 82.

[0131] (3) As shown in Figure 1 and Figure 5c, the first fabric layer 11 and the second fabric layer 12 are rolled by the roller pressing assembly 83, so that the lower surface of the first fabric layer 11 comes into contact with the upper surface of the second fabric layer 12, and the lower surface of the first fabric layer 11 and the upper surface of the second fabric layer 12 are bonded together by multiple first adhesive layers 3 to obtain an adhesive body 5.

[0132] (4) As shown in Figures 1 and 5d, the adhesive body 5 is wound up using the winding device 84. During winding, the winding device 84 rotates, and the adhesive body 5 is wound sequentially along the length direction L onto the winding device 84 to form multiple winding loops. The winding loops are bonded together by multiple second adhesive layers 4, thereby obtaining a cylindrical stacked body 6. After winding is completed, the stacked body 6 is removed from the winding device 84.

[0133] (5) As shown in Figures 5e to 5j, the superimposed body 6 is cut using a cutting device to obtain multiple cut bodies 62, which are multiple curtain bodies 7. The structure of the curtain body 7 after unfolding is shown in Figures 6a and 6b.

[0134] [Second Embodiment]

[0135] As shown in Figures 13a to 13f, this application embodiment provides a curtain 7 having a second width direction X, a second thickness direction Y, and a height direction Z that are perpendicular to each other. The curtain 7 includes a plurality of slats 70 arranged sequentially along the height direction Z; each slat 70 is provided with a plurality of first connecting portions 701 and a plurality of second connecting portions 702. The first connecting portions 701 and the second connecting portions 702 are integrally formed with the slats 70. The plurality of first connecting portions 701 and the plurality of second connecting portions 702 are alternately spaced along the second thickness direction Y (i.e., the first connecting portions 701 and the second connecting portions 702 are staggered along the second thickness direction Y). Both the first connecting portions 701 and the second connecting portions 702 extend continuously along the second width direction X (i.e., both the first connecting portions 701 and the second connecting portions 702 are elongated structures extending along the second width direction X).

[0136] Along the height direction Z, there are multiple first joints 701 on every two adjacent slats 70, and multiple second joints 702 on every two adjacent slats 70. Adjacent slats 70 refer to two slats 70 that are stacked adjacently along the height direction Z.

[0137] Along the height direction Z, in every three adjacent slats 70, multiple first joints 701 on two adjacent slats 70 are connected one-to-one (i.e., multiple first joints 701 on one slat 70 are connected one-to-one with multiple first joints 701 on another slat 70), and multiple second joints 702 on the other two adjacent slats 70 are connected one-to-one (i.e., multiple second joints 702 on one slat 70 are connected one-to-one with multiple second joints 702 on another slat 70), while other parts of adjacent slats 70 are not connected to each other, so that the curtain body 7 forms a multi-layer honeycomb structure along the second thickness direction Y (i.e., multiple cavities 700 are formed in the curtain body 7 along the second thickness direction Y).

[0138] In this configuration, each pair of adjacent slats 70 forms multiple spaced connection portions 70A at multiple first joint portions 701 or multiple second joint portions 702. As shown in Figures 13a and 13b, when the curtain 7 is unfolded, each pair of adjacent slats 70 forms a cavity 700 between each pair of adjacent connection portions 70A, that is, the curtain 7 has a structure with multiple layers of cavities 700 (Figures 13a and 13b illustrate a structure with three layers of cavities 700 in the curtain 7).

[0139] Existing honeycomb blinds generally have a single-layer honeycomb structure, meaning that there is only one cavity in the blind along the thickness direction. This makes the blind structure relatively simple and results in insufficient aesthetics, light-blocking and sound insulation performance, and heat insulation performance.

[0140] The curtain 7 provided in this embodiment of the application is configured with multiple slats 70, each slat 70 having multiple first connecting portions 701 and multiple second connecting portions 702 spaced alternately at intervals. In every three adjacent slats 70, the multiple first connecting portions 701 on two adjacent slats 70 are connected one-to-one, and the multiple second connecting portions 702 on the other two adjacent slats 70 are connected one-to-one, thereby forming a multi-layer honeycomb structure in the curtain 7, that is, forming multiple layers of cavities 700 in the curtain 7. When the multi-layer honeycomb structure curtain 7 is used as a finished product, it not only improves the structural richness of the curtain 7, thereby improving the aesthetics of the curtain 7, but also improves the light-blocking and sound-insulating performance, heat insulation performance, etc. of the curtain 7.

[0141] Of course, the multi-layered honeycomb structure curtain 7 can also be used as a semi-finished product. By cutting the curtain 7, various other curtains with different structures can be obtained. For example, by cutting the curtain 7, curtain structures as shown in Figure 6a, Figure 10c, or Figure 12c can be obtained. When cutting the curtain 7, since the cutting surface needs to pass through the first joint 701 or the second joint 702, the first joint 701 and the second joint 702 need to have sufficient width, that is, the connecting part 70A needs to have sufficient width to ensure that after cutting, adjacent curtain panels 70 have sufficient connection area and connection strength at the cut.

[0142] Therefore, the multi-layer honeycomb structure curtain 7 in this embodiment can be used directly as a finished product or cut into multiple smaller curtains as a semi-finished product, thereby enabling the production of multiple curtains at once and improving production efficiency.

[0143] As shown in Figures 13a to 13f, in one embodiment, each slat 70 has at least three of one of the first connecting portions 701 and the second connecting portions 702, and at least two of the other, thus forming a three-layer honeycomb curtain structure for the curtain body 7. In this embodiment, each slat 70 has three first connecting portions 701 and two second connecting portions 702. Of course, in other embodiments, the number of both the first connecting portions 701 and the second connecting portions 702 can be two, in which case the curtain body 7 forms a double-layer honeycomb curtain structure. Of course, the number of the first connecting portions 701 and the second connecting portions 702 can be more, especially when the curtain body 7 is a semi-finished product, the number of the first connecting portions 701 and the second connecting portions 702 is generally not less than 5, or not less than 8, or not less than 10, etc., so that more small curtain bodies can be obtained at once during cutting.

[0144] In one implementation, the number of curtain slats 70 in the curtain body 7 is generally no less than 5, or no less than 10, or no less than 15, etc.

[0145] As shown in Figures 13e and 13f, in one embodiment, when the curtain 7 is folded, the curtain slats 70 are rectangular sheet structures that are parallel to the second width direction X and the second thickness direction Y and perpendicular to the height direction Z.

[0146] As shown in Figures 13e and 13f, in one embodiment, the width B1 of the corresponding first joint portion 701 on each pair of adjacent slats 70 is equal, and the width B2 of the corresponding second joint portion 702 on each pair of adjacent slats 70 is equal.

[0147] As shown in Figures 13e and 13f, in one embodiment, along the second thickness direction Y, the width B1 of the first joint 701 and the width B2 of the second joint 702 are both 3mm to 10mm, that is, the width of the connecting part 70A is 3mm to 10mm, thus providing sufficient width for cutting. The width B1 of the first joint 701 and the width B2 of the second joint 702 can be equal or unequal (in this embodiment, since the curtain 7 is cut from a larger curtain, the first joints 701 on both sides of the curtain 7 are cut off by half, making the width of the first joints 701 on both sides of the curtain 7 smaller than the width of the first joint 701 in the middle and the width of the second joint 702).

[0148] As shown in Figures 13e and 13f, in one embodiment, when the curtain 7 is folded, the distance B3 between each adjacent first joint 701 and second joint 702 in each curtain slat 70 is equal, and the distance B3 between each adjacent first joint 701 and second joint 702 is greater than the width B1 of the first joint 701 and the width B2 of the second joint 702.

[0149] As shown in Figures 13e and 13f, in one embodiment, when the curtain 7 is folded, along the second thickness direction Y, the distance B4 between adjacent first joints 701 is 10mm to 50mm, the distance B5 between adjacent second joints 702 is 10mm to 50mm, and the distance B4 between each adjacent first joint 701 is equal to the distance B5 between each adjacent second joint 702.

[0150] As shown in Figures 13c to 13f, in one embodiment, adjacent slats 70 in the curtain body 7 are bonded together by adhesive layers. Specifically, along the second thickness direction Y, in every three adjacent slats 70, multiple first joints 701 on two adjacent slats 70 are bonded one-to-one by multiple first adhesive layers 71 (i.e., multiple first joints 701 on one slat 70 are bonded one-to-one with multiple first joints 701 on another slat 70 by multiple first adhesive layers 71), and multiple second joints 702 on two other adjacent slats 70 are bonded one-to-one by multiple second adhesive layers 72 (i.e., multiple second joints 702 on one slat 70 are bonded one-to-one with multiple second adhesive layers 72).

[0151] Specifically, multiple first adhesive layers 71 correspond one-to-one with multiple first bonding portions 701, and multiple second adhesive layers 72 correspond one-to-one with multiple second bonding portions 702. Each first adhesive layer 71 and each second adhesive layer 72 extends continuously along the second width direction X (i.e., both the first adhesive layer 71 and the second adhesive layer 72 are elongated structures extending along the second width direction X), and the multiple first adhesive layers 71 and the multiple second adhesive layers 72 are alternately arranged along the second thickness direction Y (i.e., the first adhesive layers 71 and the second adhesive layers 72 are staggered along the second thickness direction Y). The width of the first adhesive layer 71 is equal to the width B1 of the corresponding first bonding portion 701, and the width of the second adhesive layer 72 is equal to the width B2 of the corresponding second bonding portion 702.
