Description

Technical Field

[0001] The present application relates to the technical field of sewing equipment, and in particular to a 3D mesh quilting device and a quilting method. Background Art

[0002] 3D mesh, commonly known as extra-thick, or 3D mesh, is a new pure fabric material with excellent breathability, elasticity, and support. 3D mesh is constructed using a unique double-layer warp knitting process, in which high-stretch polyester yarn with high resilience and support is woven between the two layers of fabric. This creates a fabric that combines cushioning and rebound comfort. The mesh surface and plain weave back layer create a breathable, heat-dissipating, soft, and comfortable surface, while the back layer offers a stiff and smooth feel. The middle layer provides both support and resilience.

[0003] The quilting process refers to the process of sewing a layer of fabric to fix the cotton wool inside.

[0004] At present, quilting equipment mainly includes a fabric fixing platform, a three-axis movable platform and a quilting head. The fabric fixing platform is used to fix the fabric. The three-axis movable platform drives the quilting head to move on the fixed platform, so that the quilting head can quilt the fabric on the fixed platform.

[0005] Regarding the above-mentioned related technologies, since the 3D mesh has a certain thickness and is very fluffy, when the 3D mesh processing technology is poor or the protection during the 3D mesh transportation process is poor, it is easy for pits to appear in some parts of the 3D mesh, which leads to uneven thickness of the 3D mesh. This uneven thickness will lead to uneven stitches during quilting, thereby affecting the beauty and firmness of the quilting effect. Summary of the Invention

[0006] The present application provides a 3D mesh quilting device and a quilting method, the purpose of which is to eliminate or reduce the uneven thickness of the 3D mesh during the quilting process of the 3D mesh, thereby increasing the uniformity of the stitches during the quilting process, thereby increasing the beauty and firmness of the quilting process.

[0007] In the first aspect, the present application provides a 3D mesh quilting device that adopts the following technical solutions:

[0008] A 3D mesh quilting device comprises a quilting mechanism, wherein a thickness adjustment mechanism is provided on one side of the quilting mechanism;

[0009] The quilting mechanism includes a quilting head and a quilting platform, wherein the quilting head and the quilting platform are spaced apart in a vertical direction;

[0010] The thickness adjustment mechanism includes a preheating component and a hot pressing component, and the preheating component includes a heating platform capable of heating the 3D mesh;

[0011] The hot pressing assembly includes a thickness adjustment platform, a thickness adjustment plate is provided on the upper side of the thickness adjustment platform, and a thickness adjustment driving member capable of driving the thickness adjustment plate to move in a vertical direction is provided on the thickness adjustment plate;

[0012] The heating platform is spaced apart from the quilting platform along its length direction, and the thickness adjustment platform is located between the heating platform and the quilting platform;

[0013] The heating platform, the thickness adjustment platform and the quilting platform are provided with a conveying mechanism capable of conveying 3D mesh.

[0014] By adopting the above technical solution, firstly, the quilting head and the quilting platform in the quilting mechanism can realize the fixation and quilting processing of the 3D mesh.

[0015] Secondly, a heating platform is provided before the quilting mechanism. When the 3D mesh passes through the heating platform, the heating platform can heat the 3D mesh to soften the 3D mesh.

[0016] A thickness adjustment platform is provided between the heating platform and the quilting platform, and a thickness pressing plate and a thickness pressing drive are provided on the thickness adjustment platform. Therefore, the 3D mesh cloth after heating and softening can be moved to the thickness adjustment platform, and the thickness pressing plate moves downward to compress the 3D mesh cloth. Then, after the 3D mesh cloth is cooled and shaped, the thickness of the 3D mesh cloth can be adjusted.

[0017] The conveying mechanism is used to convey the 3D mesh between the heating platform, the thickness adjustment platform and the quilting platform.

[0018] Therefore, before the quilting process of the 3D mesh, the 3D mesh is softened so that the thickness of the 3D mesh can be changed. The 3D mesh is pressed down by a thickening plate, so that the protruding parts of the 3D mesh are pressed down, while the concave parts are subjected to less or no pressure. Therefore, the thickness of each part of the 3D mesh can be adjusted to be consistent, thereby improving the overall thickness uniformity of the 3D mesh. Therefore, the processing effect and aesthetics of the quilting process of the 3D mesh can be improved.

[0019] Optionally, a heating tank is provided on the heating platform, and the heating tank is connected to a hot water supply pipe capable of inputting hot water;

[0020] A first support plate is provided on the heating platform, the first support plate is plugged into the heating groove in the vertical direction, the first support plate is slidably connected to the inner wall of the heating groove in the vertical direction, and a support driving member is provided on the lower side of the first support plate that can drive the first support plate to move in the vertical direction.

[0021] By adopting the above technical solution, a heating tank is provided on the heating platform, which is connected to a hot water supply pipe. A first support plate is inserted vertically into the heating tank, and the first support plate is able to move in the vertical direction. Therefore, when the 3D mesh moves onto the first support plate, the first support plate moves downward, allowing the 3D mesh to fall into the heating tank. By passing hot water into the heating tank, the 3D mesh can be heated in a hot water bath, ensuring that the 3D mesh is heated evenly and can be cleaned.

[0022] After cleaning is completed, the first support plate moves up to send the 3D mesh back to the upper side of the heating platform.

[0023] Such a setting can achieve the heating of the 3D mesh and also facilitate the movement of the 3D mesh.

[0024] Optionally, the conveying mechanism includes a first conveying component, the first conveying component is located on one side in the width direction of the first support plate; the first conveying component includes a first conveying roller group and a second conveying roller group, the first conveying roller group and the second conveying roller group are arranged at intervals along the length direction of the first support plate; the second conveying roller group is slidably connected to the heating platform along the length direction of the first support plate, and the second conveying roller group is connected to a linear drive member capable of driving the second conveying roller group to move along the length direction of the first support plate; the first conveying roller group includes a mounting plate, and the mounting plate is provided with an active roller and a driven roller at intervals in the vertical direction on one side of the mounting plate facing the first support plate, and the active roller and the driven roller are both rotatably connected to the mounting plate, the axial direction of the active roller and the axial direction of the driven roller are parallel to each other and are arranged along the width direction of the first support plate, the active roller is coaxially connected to a driving motor, and the active roller and the driven roller are located on the upper side of the first support plate in the vertical direction.

[0025] By adopting the above technical solution, first, in the first conveying roller group, the active roller and the driven roller are arranged at intervals in the vertical direction, one end of the active roller is connected to a driving motor, and the driven roller is rotatably connected to the mounting plate, so when the 3D mesh moves between the active roller and the driven roller, the active roller rotates to convey the 3D mesh along the length direction of the first support plate.

[0026] Secondly, the second conveyor roller group has the same structure as the first conveyor roller group, so the cooperation between the two can improve the stability of 3D mesh conveying.

[0027] In addition, the second conveyor roller group can move along the length direction of the first support plate. Therefore, when the 3D mesh is fed into the second conveyor roller group, moving the second conveyor roller group can quickly convey the 3D mesh along the length direction of the first support plate. On the one hand, the 3D mesh can be pulled to prevent the 3D mesh from wrinkling; on the other hand, the conveying speed of the 3D mesh can be accelerated.

[0028] Optionally, a vertical slide groove is provided on the side of the mounting plate facing the first support plate, and the vertical slide groove passes through the mounting plate along the width direction of the first support plate; the active roller and the driven roller are both plugged into the vertical slide groove along their own axes, and the active roller and the driven roller are both rotatably connected to the inner wall of the vertical slide groove; the active roller and the driven roller are both slidably connected to the inner wall of the vertical slide groove in the vertical direction, and a vertical driving member is provided between the active roller and the driven roller, which can drive the active roller and the driven roller to move closer to or away from each other in the vertical direction.

[0029] By adopting the above technical solution, the vertical slide groove on the mounting plate is opened, and the vertical driving member is cooperated with the active roller and the driven roller to be able to move toward and away from each other in the vertical direction. Therefore, when the active roller and the driven roller in the second conveyor roller group move toward each other, the fixing force of the second conveyor roller group on the 3D mesh can be improved, so that the second conveyor roller group can better pull the 3D mesh to move to the first support plate.

[0030] Among them, since the 3D mesh itself is elastic, when the width of the first support plate is smaller than the width of the 3D mesh, the first support plate transports the 3D mesh upward from the heating tank, and the driven roller will resist the deformation of the 3D mesh. When the 3D mesh continues to be transported upward, the 3D mesh can return to its original shape, and then the 3D mesh can be moved back between the driven roller and the active roller. Therefore, the second conveying roller group can realize the conveyance of the 3D mesh toward the thickness adjustment platform.

[0031] Optionally, a plurality of first paving grooves are provided on the first support plate, and the first paving grooves are arranged in one-to-one correspondence with the driven rollers, and the first paving grooves are arranged opposite to the driven rollers in the vertical direction, and the driven rollers are slidingly connected to the inner walls of the first paving grooves in the vertical direction.

[0032] By adopting the above technical solution, the opening of the first clearance groove enables the driven roller to move to the bottom of the side surface of the first support plate, so that the first conveyor roller group and the second conveyor roller group can lay the 3D mesh flatly on the first support plate.

[0033] Optionally, the driven roller is slidably connected to the inner wall of the vertical sliding groove along its own axis, and one end of the driven roller is coaxially connected to a telescopic driving member capable of driving the driven roller to move along its own axis.

[0034] By adopting the above technical solution, when the width of the 3D mesh is smaller than the first support plate, in order to allow the 3D mesh to re-enter between the driven roller and the active roller, the driven roller is slidably connected to the vertical chute along its own axis. Therefore, when the driven roller retracts into the vertical chute, the 3D mesh can be laid flat on the first support plate; at the same time, when the driven roller extends out of the vertical chute, the 3D mesh can be moved back between the active roller and the driven roller, thereby realizing the continued transportation of the 3D mesh.

[0035] Optionally, a first closing plate is provided on the upper side of the heating platform, and a first positioning groove is provided on the side of the first closing plate facing the heating platform, and the first positioning groove passes through the first closing plate along the length direction of the first support plate; the first support plate is located in the first positioning groove; first sealing plates capable of closing the first positioning groove are provided on both sides of the length direction of the first closing plate, the first sealing plate is slidably connected to the first closing plate in the vertical direction, and a sealing driving member capable of driving the first sealing plate to slide in the vertical direction is provided on the first sealing plate.

[0036] By adopting the above technical solution, a first closing plate is provided on the heating platform, the first closing plate has a first seating groove, and cooperates with a first sealing plate capable of sealing the first seating groove. Therefore, an enclosed space can be formed on the heating platform, thereby increasing the heating speed of the 3D mesh and reducing the heat dissipation speed of the hot water when the 3D mesh is heated.

[0037] Optionally, a second closing plate is provided on the upper side of the thickness adjusting platform, and a second positioning groove is provided on the second closing plate facing the side of the thickness adjusting platform, and the second positioning groove passes through the second closing plate along the length direction of the thickness adjusting platform; second sealing plates capable of closing the second positioning groove are provided on both sides of the length direction of the second closing plate, and the second sealing plate is slidingly connected to the second closing plate in the vertical direction, and a first auxiliary driving member capable of driving the second sealing plate to move in the vertical direction is provided on the second sealing plate; the thickness pressing plate is located in the second positioning groove.

[0038] By adopting the above technical solution, a second closing plate is provided on the thickness adjustment platform, the second closing plate has a second positioning groove, and cooperates with a second sealing plate that can close the second positioning groove. Therefore, a closed space can be formed on the thickness adjustment platform, so that the temperature of the space in the second positioning groove is uniform, and the flow of external air is prevented from causing different cooling rates of various parts of the 3D mesh cloth, resulting in poor thickness adjustment effect of the 3D mesh cloth.

[0039] Optionally, an air inlet and an air outlet are provided on the second closing plate, and the air inlet and the air outlet are both interconnected with the second seating groove, and the air inlet and the air outlet are connected to a hot air circulation system that can provide hot air.

[0040] By adopting the above technical solution, the hot air circulation system is connected through the air inlet and the air outlet, and hot air can be introduced to achieve rapid drying and cooling and shaping of the 3D mesh.

On this basis, quilting is performed on the 3D mesh, which can improve the elimination or reduction of the uneven thickness of the 3D mesh, thereby increasing the uniformity of the stitches during quilting, thereby increasing the beauty and firmness of the quilting process.

[0081] The following is combined with Figure 1 -Attached Figure 11 , further details of this application are given.

[0082] A 3D mesh quilting device, referring to Figure 1 , including a quilting mechanism 1 and a thickness adjustment mechanism 2, the quilting mechanism 1 includes a quilting head 11 and a quilting platform 12, the quilting head 11 is located on the upper side of the quilting platform 12 along the vertical direction,

[0083] Therefore, after the 3D mesh moves to the quilting platform 12, the quilting head 11 can perform quilting processing on the 3D mesh.

[0084] Reference Figure 1 The thickness adjustment mechanism 2 includes a preheating component 21 and a hot pressing component 22. The preheating component 21 and the hot pressing component 22 are arranged in sequence along the horizontal direction, and the quilting platform 12 is located on the side of the hot pressing component 22 away from the preheating component 21.

[0085] Therefore, the 3D mesh first enters the preheating component 21 to heat the 3D mesh and soften it; then the 3D mesh is moved to the hot pressing component 22 to fix the thickness of the 3D mesh, so that the thickness of the 3D mesh discharged from the thickness adjustment mechanism 2 can be uniform, which can make the final quilting process have a better processing effect.

[0086] Reference Figure 1 The quilting equipment further includes a conveying mechanism 3, which includes a first conveying assembly 31, a second conveying assembly 32, and a third conveying assembly 33. The first conveying assembly 31 is mounted on the preheating assembly 21, the second conveying assembly 32 is mounted on the hot pressing assembly 22, and the third conveying assembly 33 is mounted on the quilting platform 12. Therefore, the arrangement of the first conveying assembly 31, the second conveying assembly 32, and the third conveying assembly 33 can realize the conveyance of 3D mesh.

[0087] Reference Figure 2 and Figure 3 The preheating assembly 21 includes a heating platform 211, a heating tank 2111 is provided on the upper side of the heating platform 211, a first support plate 212 is vertically inserted into the heating tank 2111, and the first support plate 212 is vertically slidably connected to the inner wall of the heating tank 2111. A plurality of support driving members 213 are provided on the lower side of the first support plate 212. The support driving members 213 are arranged in the vertical direction, and the two ends of the support driving members 213 are respectively connected to the first support plate 212 and the bottom of the heating tank 2111. In the present application, the support driving members 213 can be hydraulic push rods, pneumatic push rods, or electric push rods.

[0088] Therefore, the first support plate 212 can move to above the upper side of the heating platform 211. At this time, the first support plate 212 can support the 3D mesh. When the first support plate 212 moves downward, the 3D mesh will fall into the heating tank 2111, so that the 3D mesh can be heated.

[0089] Reference Figure 2 and Figure 3Two hot water tanks 2112 are provided within the heating platform 211. The two hot water tanks 2112 are located on either side of the heating tank 2111 in the width direction. Through holes 2113 are provided on both side walls of the heating tank 2111 along its width direction. The through holes 2113 respectively connect the heating tank 2111 with the corresponding hot water tank 2112. A circulation pipe 2114 is provided on the lower side of the heating platform 2111. The two ends of the circulation pipe 2114 are respectively connected to the corresponding hot water tank 2112. A circulation water pump 2115 is provided on the circulation pipe 2114. The circulation pipe 2114 is connected to a hot water supply pipe 2116, which is connected to a hot water supply pump.

[0090] Therefore, the hot water supply pump can discharge hot water into the hot water tank 2112 and then into the heating tank 2111, thereby heating the 3D mesh. The circulation pipe 2114 and the circulation water pump 2115 cooperate to circulate the hot water between the heating tank 2111 and the two hot water tanks 2112, ensuring the uniformity of the hot water temperature in the heating tank 2111, improving the uniformity of heating the 3D mesh, and also allowing the 3D mesh to be cleaned.

[0091] Reference Figure 2 and Figure 3 A first sealing plate 214 is provided on the upper side of the heating platform 211, and a first seating groove 2141 is provided on the lower side of the first sealing plate 214. The first seating groove 2141 penetrates the first sealing plate 214 along the length direction of the first sealing plate 214. First sealing plates 2142 are provided on both sides of the length direction of the first sealing plate 214. The first sealing plates 2142 are slidably connected to the first sealing plate 214 in the vertical direction. A sealing driver 2143 is connected to the first sealing plate 2142. The sealing driver 2143 adopts a cylinder or an electric push rod. The sealing driver 2143 is provided in the vertical direction, and the two ends of the sealing driver 2143 are respectively connected to the first sealing plate 2142 and the first sealing plate 214.

[0092] Therefore, the first seating groove 2141 cooperates with the first closing plate 214 to close the space above the heating platform 211 , thereby improving the heating effect of the heating platform 211 on the 3D mesh.

[0093] Reference Figure 3 and Figure 4 The first conveying assembly 31 is vertically positioned between the first sealing plate 214 and the heating platform 211 and is positioned on one side of the first support plate 212 along the width direction of the first support plate 212. The first conveying assembly 31 includes a first conveying roller set 311, which is positioned away from the hot pressing assembly 22 along the length direction of the heating platform 211.

[0094] Reference Figure 4 and Figure 5The first conveying roller group 311 includes a mounting plate 3111, and an active roller 3112 and a driven roller 3113 are provided on the side of the mounting plate 3111 facing the first support plate 212. The axial directions of the active roller 3112 and the driven roller 3113 are arranged parallel to each other and are both arranged along the width direction of the first support plate 212. The active roller 3112 and the driven roller 3113 are arranged to be spaced apart from each other in the vertical direction.

[0095] Reference Figure 4 and Figure 5 A vertical sliding groove 3114 is provided on one side of the mounting plate 3111 facing the first support plate 212 . The length direction of the vertical sliding groove 3114 is arranged along the vertical direction and the vertical sliding groove 3114 passes through the mounting plate 3111 along the width direction of the first support plate 212 .

[0096] Reference Figure 4 and Figure 5 The active roller 3112 and the driven roller 3113 are both plugged into the vertical slide groove 3114 along their own axes, and the active roller 3112 and the driven roller 3113 are both rotatably connected to the inner wall of the vertical slide groove 3114. The active roller 3112 is coaxially connected to the drive motor 3115, and the drive motor 3115 is interconnected with the mounting plate 3111.

[0097] Therefore, the driving motor 3115 drives the active roller 3112 to rotate, so that when the 3D mesh is located between the active roller 3112 and the driven roller 3113 , the 3D mesh can be transported along the length direction of the first support plate 212 .

[0098] Reference Figure 4 and Figure 5 The driven roller 3113 is slidably connected to the inner wall of the vertical slide 3114 along its own axis. A telescopic drive member 3116 is provided at one axial end of the driven roller 3113. The telescopic drive member 3116 is implemented as a pneumatic cylinder, an oil cylinder, or an electric push rod. The output shaft of the telescopic drive member 3116 is interconnected with the driven roller 3113. Therefore, when the 3D mesh needs to be placed on the first support plate 212, the driven roller 3113 needs to give way. Therefore, when the driven roller 3113 is retracted into the mounting plate 3111, the 3D mesh can be placed on the first support plate 212.

[0099] Reference Figure 4 and Figure 5The active roller 3112 and the driven roller 3113 both slide along the vertical direction with the inner wall of the vertical slide groove 3114. A vertical driving member 3118 is arranged between the active roller 3112 and the driven roller 3113. The vertical driving member 3118 is composed of a double-rod cylinder or two cylinders. The vertical driving member 3118 is arranged along the vertical direction and the two output ends of the vertical driving member 3118 are respectively connected to the active roller 3112 and the driven roller 3113. Therefore, the active roller 3112 and the driven roller 3113 can be moved along the vertical direction to realize the movement of the active roller 3112 and the driven roller 3113 closer to or away from each other.

[0100] Reference Figure 4 and Figure 5 The first conveyor roller assembly 311 further includes an installation box 3117. The opening of the installation box 3117 is disposed along the width direction of the first support plate 212, facing the first support plate 212. The installation plate 3111 is plugged into the opening of the installation box 3117 along the width direction of the first support plate 212. The lower side of the installation box 3117 is connected to the heating platform 211. Therefore, the installation box 3117 enables the installation of the installation plate 3111.

[0101] Reference Figure 4 and Figure 5 The first conveyor assembly 31 also includes a second conveyor roller set 312. The second conveyor roller set 312 is located along the length of the heating platform 211 on the side of the first conveyor roller set 311 facing the hot pressing assembly 22. The first conveyor roller set 311 and the second conveyor roller set 312 have the same structure. Therefore, the second conveyor roller set 312 can cooperate with the first conveyor roller set 311 to improve the stability of the 3D mesh conveying.

[0102] Reference Figure 4 and Figure 5 A linear drive 313 is provided on the side of the second conveyor roller set 312 facing away from the first support plate 212. The second conveyor roller set 312 is slidably connected to the heating platform 211 along the length of the heating platform 211. The linear drive 313 utilizes a linear module, a pneumatic cylinder, or an electric push rod. The output ends of the second conveyor roller set 312 and the linear drive 313 are interconnected. Therefore, after the second conveyor roller set 312 clamps the 3D mesh, the linear drive 313 pulls the 3D mesh onto the first support plate 212, thereby increasing the conveying speed of the 3D mesh.

[0103] Reference Figure 4 and Figure 5 There are two first conveying assemblies 31, which are located on both sides of the first support plate 212 in the width direction and are arranged opposite each other along the width direction of the first support plate 212. Therefore, the cooperation of the two first conveying assemblies 31 can improve the stability of 3D mesh conveying.

[0104] Reference Figure 4 and Figure 5 The first support plate 212 is provided with four first clearance slots 2121. These slots 2121 extend vertically through the first support plate 212 and correspond one to each of the driven rollers 3113. Each slot 2121 is vertically positioned below the corresponding driven roller 3113. When the driven roller 3113 moves vertically, the inner sidewalls of the first clearance slots 2121 become spaced apart from or slidably connected to the sidewalls of the corresponding driven roller 3113. Therefore, the provision of the first clearance slots 2121 allows the driven roller 3113 to move below the upper side of the first support plate 212, allowing the 3D mesh to be laid flat on the first support plate 212.

[0105] Reference Figure 4 and Figure 5 The first support plate 212 is provided with two second clearance grooves 2122. The second clearance grooves 2122 extend vertically through the first support plate 212 and are spaced apart from each other along the width direction of the first support plate 212. The second clearance grooves 2122 are located along the length direction of the first support plate 212 on the side of the first clearance groove 2121 facing the hot pressing assembly 22. The second clearance grooves 2122 are arranged in a one-to-one correspondence with the driven rollers 3113 of the second conveying roller set 312. When the driven rollers 3113 of the second conveying roller set 312 move along the length direction of the first support plate 212 to the side close to the hot pressing assembly 22, the driven rollers 3113 in the second conveying roller set 312 and the second clearance grooves 2122 are arranged in a one-to-one correspondence along the vertical direction. When the driven roller 3113 in the second conveying roller set 312 moves in the vertical direction, the driven roller 3113 and the inner side wall of the corresponding second clearance groove 2122 are spaced apart from each other or slidably connected to each other.

[0106] Therefore, when it is necessary to convey the heated 3D mesh on the first support plate 212 to the hot pressing assembly 22, the driven roller 3113 of the second conveying roller group 312 can be moved to the corresponding second give way groove 2122. At this time, the 3D mesh is located between the driven roller 3113 and the active roller 3112, so that the 3D mesh can be conveyed again.

[0107] Reference Figure 1 and Figure 6 The hot pressing assembly 22 includes a thickness adjusting platform 221 , which is connected to the heating platform 211 along one side of its length direction. The length direction of the thickness adjusting platform 221 is the same as that of the heating platform 211 .

[0108] Reference Figure 6 and Figure 7A second support plate 222 is provided on the thickness adjustment platform 221. The first support plate 212 and the second support plate 222 have the same structure. A second conveying assembly 32 is located on the thickness adjustment platform 221. The second conveying assembly 32 includes a third conveying roller set 321, a fourth conveying roller set 322, and a second auxiliary drive member 323. The third conveying roller set 321 has the same structure as the first conveying roller set 311, the fourth conveying roller set 322 has the same structure as the second conveying roller set 312, and the second auxiliary drive member 323 has the same structure as the linear drive member 313. The second auxiliary drive member 323 and the fourth conveying roller set 322 are interconnected. Therefore, the second conveying assembly 32 has the same function as the first conveying assembly 31. The 3D mesh can be transported to the thickness adjustment platform 221 by the first conveying assembly 31, moved to the second support plate 222 by the second conveying assembly 32, and then transported to the quilting platform 12 by the second conveying assembly 32.

[0109] Reference Figure 6 and Figure 7 A second sealing plate 223 is installed on the upper side of the thickness adjustment platform 221. The second sealing plate 223 has the same structure as the first sealing plate 214. A second seating groove 2231 is provided on the second sealing plate 223, which has the same structure as the first seating groove 2141. Second sealing plates 2232, which have the same structure as the first sealing plate 2142, are installed on both sides of the second sealing plate 2232 along its length. A first auxiliary driving member 2233, which has the same structure as the sealing driving member 2143, is installed on the second sealing plate 2232. Therefore, the 3D mesh can be moved to the second seating groove 2231.

[0110] Reference Figure 6 and Figure 7 The second closing plate 223 is provided with an air inlet 2234 and an air outlet 2235, both of which are in communication with the second clearance groove 2122. The air inlet 2234 is connected to the air inlet duct, and the air outlet 2235 is connected to the air outlet duct, and the air inlet duct and the air outlet duct are connected to a hot air circulation system.

[0111] Therefore, after the second sealing plates 2232 on both sides of the second closing plate 223 close the second positioning groove 2231, hot air is introduced through the air inlet 2234, and the air in the second positioning groove 2231 is discharged through the air outlet 2235, so that the 3D mesh can be dried; and in the process of continuously lowering the temperature of the hot air, the 3D mesh can be dried and shaped.

[0112] Reference Figure 6 and Figure 7The thickness adjustment platform 221 is also provided with two movable plates 2211. The two movable plates 2211 are located on both sides of the second support plate 222 along the width direction of the thickness adjustment platform 221. The movable plates 2211 are located on the thickness adjustment platform 221 and are slidably connected to the thickness adjustment platform 221 along the width direction of the thickness adjustment platform 221. The movable plates 2211 are arranged in a one-to-one correspondence with the second conveying roller groups 312, and the second conveying roller groups 312 are mounted on the corresponding movable plates 2211. A clearance drive member 2212 is provided on the lower side of the movable plate 2211. The clearance drive member 2212 adopts a linear module and is arranged along the width direction of the thickness adjustment platform 221. The clearance drive member 2212 is connected to the corresponding movable plate 2211.

[0113] Therefore, the corresponding second conveying roller set 312 can be driven by the yielding driving member 2212 to move along the width direction of the second support plate 222 , thereby moving the third conveying roller set 321 and the fourth conveying roller set 322 away from the upper side of the second support plate 222 .

[0114] Reference Figure 7 and Figure 8 A pressing plate 2213 is provided on the inner wall of the second seating groove 2231. The pressing plate 2213 is vertically spaced apart and arranged on the upper side of the second support plate 222. The pressing plate 2213 and the second support plate 222 are arranged vertically opposite each other. A pressing drive 2214 is provided on the side of the pressing plate 2213 facing away from the second support plate 222. The pressing drive 2214 is implemented by a pneumatic cylinder, a hydraulic cylinder, or a linear motor. The pressing drive 2214 is interconnected with the second closing plate 223. Therefore, when the 3D mesh is positioned on the second support plate 222, the thickness of the 3D mesh can be adjusted by lowering the pressing plate 2213 and adjusting the distance between the pressing plate 2213 and the second support plate 222. Therefore, during the drying and shaping process of the 3D mesh, the overall thickness of the 3D mesh can be adjusted so that the thickness at each location on the 3D mesh is uniform.

[0115] Reference Figure 7 and Figure 8 Two width limiting grooves 2215 are provided on the thickness adjustment platform 221. The two width limiting grooves 2215 are located on both sides of the width direction of the second support plate 222 along the width direction of the second support plate 222. The length direction of the width limiting grooves 2215 is set along the length direction of the second support plate 222.

[0116] Reference Figure 8 and Figure 9A width limiting plate 2216 is inserted into the width limiting groove 2215, and a plurality of filling blocks 2217 are provided on the side of the width limiting plate 2216 facing the support plate. The plurality of filling blocks 2217 are arranged one-to-one corresponding to the first make way groove 2121 and the second make way groove 2122 on the second support plate 222. The width limiting plate 2216 is slidably connected to the inner wall of the width limiting groove 2215 along the vertical direction. A limited driving member 2218 is connected to the width limiting plate 2216. The limited driving member 2218 is arranged in the vertical direction and the limited driving member 2218 adopts a cylinder or an electric push rod. Therefore, the limiting drive 2218 can push the width limiting plate 2216 to move in the vertical direction, so that the filling block 2217 can close the corresponding first make way groove 2121 or the second make way groove 2122 on the second support plate 222, and then fill the gap on the second support plate 222, so that all parts of the 3D mesh can be evenly stressed, thereby ensuring that the thickness of each position of the 3D mesh can be evenly adjusted.

[0117] Reference Figure 1 and Figure 10 The length direction of the quilting platform 12 is arranged along the length direction of the thickness adjustment platform 221. The quilting head 11 is provided with a two-axis movable platform 13. The two-axis movable platform 13 includes a first driving member and a second driving member. The first driving member is arranged in the vertical direction, and the second driving member is arranged in the width direction of the quilting platform 12. The second driving member is interconnected with the first driving member, and the first driving member is interconnected with the quilting head 11. The quilting head 11 is located on the upper side of the quilting platform 12 in the vertical direction. Therefore, the quilting head 11 can realize quilting processing on 3D mesh fabrics. Among them, the first driving member and the second driving member both adopt linear modules.

[0118] Reference Figure 10 and Figure 11 A third conveying assembly 33 is provided on the quilting platform 12. The third conveying assembly 33 includes a fixed frame 331. The fixed frame 331 is slidably connected to the quilting platform 12 along the length direction of the quilting platform 12. A first shaft driving member 14 is provided between the fixed frame 331 and the quilting platform 12. The first shaft driving member 14 adopts a linear module. The length direction of the first shaft driving member 14 is set along the length direction of the quilting platform 12. The output end of the first shaft driving member 14 is connected to the fixed frame 331. Therefore, the fixed frame 331 can move on the quilting platform 12 along the length direction of the quilting platform 12.

[0119] Reference Figure 10 and Figure 11A grabbing member 332 is slidably connected to the fixing frame 331 along its length. The grabbing member 332 is slidably connected to the fixing frame 331 along its length. A grabbing driver 333 is disposed between the grabbing member 332 and the fixing frame 331. The grabbing driver 333 is disposed along the length of the fixing frame 331, and its driving end is connected to the grabbing member 332. The grabbing driver 333 employs a pneumatic cylinder or an electric push rod. Therefore, the grabbing member 332 can be moved along the length of the fixing frame 331.

[0120] Reference Figure 10 and Figure 11 The grabbing member 332 includes a movable base 3321, which is slidably connected to the fixed frame 331 along its length. A grabbing plate 3322 is provided on the upper side of the movable base 3321. A pressing drive member 3323 is provided between the grabbing plate 3322 and the movable base 3321. The pressing drive member 3323 is arranged in a vertical direction, and the output end of the pressing drive member 3323 is interconnected with the grabbing plate 3322. Therefore, when the 3D mesh moves between the pressing plate and the movable base 3321, the pressing drive member 3323 can drive the pressing plate to fix the 3D mesh on the movable plate 2211, thereby achieving the grabbing of the 3D mesh.

[0121] Reference Figure 10 and Figure 11 Auxiliary pressing members 334 are spaced apart on both sides of the fixed frame 331 in the width direction. The auxiliary pressing members 334 include auxiliary pressing plates 3341. The length direction of the auxiliary pressing plates 3341 is arranged along the length direction of the fixed frame 331. A locking driving member 3342 is arranged between the auxiliary pressing plates 3341 and the fixed frame 331. The locking driving member 3342 is arranged in the vertical direction, and the output section of the locking driving member 3342 is interconnected with the auxiliary pressing plates 3341. Therefore, after the grasping member 332 grasps the 3D mesh and drives the 3D mesh to move into place, the locking driving member 3342 can drive the auxiliary pressing plates 3341 to fix the 3D mesh on the fixed frame 331, thereby achieving the fixation of the 3D mesh and thus realizing the quilting process of the 3D mesh.

[0122] The implementation principle of the embodiment of the present application is as follows: First, the 3D mesh is moved lengthwise onto the heating platform 211. After being heated in the heating tank 2111, the 3D mesh is heated and softened. The softened 3D mesh is then moved onto the thickness adjustment platform 221. The thickness pressing plate 2213 is lowered so that the lower side of the thickness pressing plate 2213 is vertically lower than the lowest point on the upper side of the 3D mesh. After being fixed, hot air is introduced and the hot air temperature is gradually lowered. During this process, the 3D mesh assembly is dried and cooled to form. At this time, the thickness of the 3D mesh is adjusted to a uniform thickness. Finally, the 3D mesh is moved onto the quilting platform 12 to achieve quilting of the 3D mesh.

[0123] In the above process, except for the loading and unloading processes of the 3D mesh, the heating, thickness adjustment and quilting of the 3D mesh are all carried out automatically, which greatly improves the speed and convenience of the 3D mesh quilting process.

[0124] This embodiment also discloses a 3D mesh quilting method, which utilizes the above-mentioned quilting equipment to perform quilting processing on the 3D mesh, comprising the following steps:

[0125] S1: Soften by heating.

[0126] S11: Send the 3D mesh onto the heating platform 211.

[0127] S12: heating the 3D mesh in a hot water bath.

[0128] Specifically, heating the 3D mesh with hot water improves heating uniformity, preventing uneven heating of the mesh, which can lead to varying deformation properties across the mesh and make it difficult to achieve uniform thickness. Furthermore, the hot water bath can clean the mesh, allowing the finished quilted product to be packaged directly.

[0129] S13: After heating is completed, the 3D mesh is transported toward the thickness adjustment platform 221 .

[0130] S2: Drying and shaping.

[0131] S21: moving the 3D mesh onto the thickness adjustment platform 221 .

[0132] S22 : lowering the pressing plate 2213 to adjust the distance between the pressing plate 2213 and the thickness adjustment platform 221 .

[0133] Specifically, the position with the deepest depression on the 3D mesh is determined, and the thickness of the 3D mesh there is determined. Then, based on the thickness value, the interval between the pressing plate 2213 and the thickness adjustment platform 221 is adjusted to be equal to or slightly less than the thickness.

[0134] S23: Ventilate and dry.

[0135] S24: After the 3D mesh is dried, the hot air temperature is gradually lowered to cool and shape the 3D mesh.

[0136] Specifically, hot air is first introduced to quickly dry the 3D mesh. After drying, since the 3D mesh is at a high temperature and is prone to deformation, the component reduces the temperature of the hot air and eventually reduces the temperature of the hot air to room temperature or below, and cools and shapes the 3D mesh component. At this time, the thickness of the 3D mesh is fixed.

[0137] S25: Move the 3D mesh toward the quilting platform 12.

[0138] S3: Quilting process.

[0139] S31: Move the 3D mesh onto the quilting platform 12.

[0140] S32: Perform quilting processing.

[0141] S33: After processing is completed, the 3D mesh is removed.

[0142] The implementation principle of the embodiment of the present application is: the 3D mesh is first heated and softened, and then the thickness is adjusted to improve the uniformity of the thickness of the 3D mesh. On this basis, quilting is performed on the 3D mesh, which can improve the elimination or reduction of the uneven thickness of the 3D mesh, and then increase the uniformity of the stitches during the quilting process, thereby increasing the beauty and firmness of the quilting process.

[0143] The examples of this specific embodiment are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, any equivalent changes made based on the structure, shape, and principle of this application should be included in the scope of protection of this application.
