[0001] The utility model relates to the technical field of processing equipment, in particular to a mattress production equipment. Background Art

[0002] A TPU (Thermoplastic polyurethanes) mattress is a mattress mainly made of TPU, which is widely used due to its advantages such as high comfort and good support.

[0003] Reference Figure 1 and Figure 2 , wherein, Figure 1 shows a three-dimensional view of the finished TPU mattress 10, Figure 2 shows a structural schematic diagram of the TPU mattress 10 before hot press welding. The finished TPU mattress 10 includes a first wall 11, a second wall 12, and a filling layer 13 located between the first wall 11 and the second wall 12 ( Figure 2 visible). Among them, the first wall 11 is formed by an upper sheet 14, and the second wall 12 is formed by a lower sheet 15.

[0004] Specifically, the lower surface of the upper sheet 14 and the upper surface 131 of the filling layer are hot press welded, and the lower surface of the upper sheet 14 bends downward to be hot press welded with the upper half of the side surface 130 of the filling layer 13, so that the upper sheet 14 forms the first wall 11 of the finished TPU mattress 10. Similarly, the upper surface 150 of the lower sheet and the lower surface of the filling layer 13 are hot press welded, and the upper surface 150 of the lower sheet 15 bends upward to be hot press welded with the lower half of the side surface 130 of the filling layer 13, so that the lower sheet 15 forms the second wall 12 of the finished TPU mattress 10. After welding, the peripheral surplus material is cut off along the welding edge, thus forming a complete finished TPU mattress 10.

[0005] During the hot press welding operation, the upper sheet 14 and the lower sheet 15 are clamped by a fixture to fix the upper sheet 14 and the lower sheet 15. As a result, after the hot press welding is completed, when unloading (i.e., removing the finished TPU mattress 10 after hot press welding), the fixture needs to be operated, resulting in inconvenient handling and time-consuming operation.

[0054] The embodiment of the present application provides a mattress production device 100 for processing Figure 1 the TPU mattress 10 as shown.

[0055] Those skilled in the art can understand that the mattress production equipment 100 of the present application can be used for hot pressing and welding of any mattress composed of a first wall 11 formed by an upper sheet 14, a second wall 12 formed by a lower sheet 15, and a filling layer 13. The present application takes the TPU mattress 10 as an example for illustration only.

[0056] Reference Figure 3 And Figure 4 Referring to

[0057] and

[0058] In this embodiment, there are two loading devices 200. In the initial state (that is, before the hot pressing and welding operation), the two loading devices 200 are respectively located on both sides of the width direction X of the hot pressing device 300, and the two loading devices 200 can alternately enter the hot pressing device 300 in sequence along its width direction X for hot pressing and welding. It is easy to understand that it takes time to place the upper sheet 14, the lower sheet 15, and the filling layer 13 on the loading device 200, and the hot pressing and welding also require waiting for a period of time. Then, the two loading devices 200 alternately enter the hot pressing device 300 in sequence, which can effectively reduce the waiting time of the hot pressing device 300, thereby improving production efficiency.

[0059] Embodiment 1

[0060] Reference Figure 3 And Figure 4 Referring to

[0061] Among them, as Figure 5 And Figure 6 shown, the upper frame 210 is used to place the upper sheet 14, and a plurality of first fixing members 230 are arranged at intervals on the upper frame 210; each first fixing member 230 includes a first puncturing portion 231, and the first puncturing portion 231 is used to puncture the upper sheet 14 (as Figure 6 shown) to fix the upper sheet 14 to the upper frame 210.

[0062] As Figure 7 And Figure 8As shown, the above-mentioned lower frame 220 is used to place the lower sheet 15, and a plurality of second fixing members 240 are arranged at intervals on the lower frame 220. Each second fixing member 240 includes a second puncturing portion 241, and the second puncturing portion 241 is used to puncture the lower sheet 15 (as Figure 8 shown) to fix the lower sheet 15 to the lower frame 220.

[0063] First, the upper sheet 14 is fixed to the upper frame 210 and the lower sheet 15 is fixed to the lower frame 220 respectively. Then, the filling layer 13 is placed on the lower sheet 15. Finally, the upper frame 210 with the upper sheet 14 is stacked on the filling layer 13 so that the upper frame 210 is aligned with the lower frame 220. At this time, the state where the upper frame 210 and the lower frame 220 are arranged opposite to each other in the height direction Z is the state about to enter the hot pressing device 300, as Figure 4 shown.

[0064] In Figure 4 the shown state, the first fixing members 230 and the second fixing members 240 are arranged alternately. That is, along the length direction Y and the width direction X of the upper frame 210 and the lower frame 220, a second fixing member 240 is inserted between two adjacent first fixing members 230. In other words, the first fixing members 230 and the second fixing members 240 are not arranged opposite to each other in the height direction Z, but are staggered from each other to avoid contact between the first fixing members 230 and the second fixing members 240.

[0065] Those skilled in the art can understand that in other embodiments, the first fixing members 230 and the second fixing members 240 can be arranged opposite to each other and at intervals in the height direction Z. That is, the lengths of the first fixing members 230 and the second fixing members 240 are set to be shorter so that the first fixing members 230 and the second fixing members 240 cannot contact each other due to the limited length.

[0066] As Figure 5 and Figure 6 shown, before the upper sheet 14 is fixed to the upper frame 210, the upper frame 210 and the lower frame 220 are placed separately, and the first fixing members 230 and the second fixing members 240 are both placed upward to facilitate puncturing the upper sheet 14 and the lower sheet 15.

[0067] With the above technical solution, the operator can place the upper sheet 14 on the upper frame 210, so that the first piercing part 231 of the first fixing part 230 on the upper frame 210 pierces the edge of the upper sheet 14, so as to fix the upper sheet 14 on the upper frame 210; similarly, place the lower sheet 15 on the lower frame 220, so that the second piercing part 241 of the second fixing part 240 on the lower frame 220 pierces the edge of the lower sheet 15, so as to fix the lower sheet 15 on the lower frame 220. Then place the filling layer 13 on the lower sheet 15, and then place the upper frame 210 on the lower frame 220, and set the upper frame 210 and the lower frame 220 opposite to each other, and the filling layer 13 is located between the upper sheet 14 and the lower sheet 15.

[0068] Next, the upper frame 210 and the lower frame 220 stacked together and arranged opposite to each other enter the hot pressing device 300 together. The hot pressing device 300 performs hot pressing and welding on the edges of the upper sheet 14 and the lower sheet 15, and the surfaces where the upper sheet 14 and the lower sheet 15 are respectively attached to the filling layer 13.

[0069] After the hot pressing and welding is completed, the upper frame 210 and the lower frame 220 are sent out of the hot pressing device 300 together. The operator removes the finished TPU mattress 10 located between the upper frame 210 and the lower frame 220, so that it is separated from the upper frame 210 and the lower frame 220.

[0070] That is, in this application, the upper frame 210 and the first fixing part 230 fix the upper sheet 14, and the lower frame 220 and the second fixing part 240 fix the lower sheet 15, eliminating the need to clamp the upper sheet 14 and the lower sheet 15 with a fixture, thus avoiding the operation of the fixture after the hot pressing and welding is completed, and further facilitating the transfer of the finished TPU mattress 10 after the hot pressing and welding is completed, improving production efficiency.

[0071] Exemplarily, in this embodiment, the upper sheet 14 and the lower sheet 15 are rectangular, and the upper frame 210 and the lower frame 220 are rectangular frames, so that the shape of the upper sheet 14 matches the shape of the upper frame 210, and the shape of the lower sheet 15 matches the shape of the lower frame 220.

[0072] It is easy to understand that in other embodiments, the upper sheet 14 and the upper frame 210, as well as the lower sheet 15 and the lower frame 220, can also be other shapes, such as oval, as long as the shapes match.

[0073] In this embodiment, the heights of the upper frame 210 and the lower frame 220 are 10 mm. However, those skilled in the art can understand that in other embodiments, the heights of the upper frame 210 and the lower frame 220 can also be other values, such as 9 mm, 9.5 mm, 11 mm, etc.

[0074] Reference Figure 4, in the embodiments of the present application, the first fixing member 230 includes a plurality of round nails 250 and a plurality of triangular nails 260.

[0075] Specifically, the upper frame body 210 includes two first long side edges 212 and two first wide side edges 211. The first long side edges 212 extend along the length direction Y of the upper frame body 210, and the first wide side edges 211 extend along the width direction X of the upper frame body 210. Each first wide side edge 211 is connected to the first long side edge 212 to form a rectangular upper frame body 210.

[0076] A plurality of round nails 250 are provided on each first long side edge 212 of the upper frame body 210, and the plurality of round nails 250 on each first long side edge 212 are arranged at intervals along the length direction Y of the upper frame body 210.

[0077] The distance between any two adjacent round nails 250 is between 30 mm and 300 mm. In this embodiment, the distance between two adjacent round nails 250 among the plurality of round nails 250 arranged at intervals on the first long side edge 212 of the upper frame body 210 is 150 mm. However, those skilled in the art can understand that in other embodiments, the distance between two adjacent round nails 250 among the plurality of round nails 250 arranged at intervals on the first long side edge 212 of the upper frame body 210 can also be 30 mm, 50 mm, 100 mm, 200 mm, 250 mm, 300 mm, etc.

[0078] A plurality of triangular nails 260 are provided on each first wide side edge 211 of the upper frame body 210, and the plurality of triangular nails 260 on each first wide side edge 211 are arranged at intervals along the width direction X of the upper frame body 210.

[0079] The distance between any two adjacent triangular nails 260 is between 30 mm and 300 mm. In this embodiment, the distance between two adjacent triangular nails 260 among the plurality of triangular nails 260 arranged at intervals on the first wide side edge 211 of the upper frame body 210 is 113.5 mm. However, those skilled in the art can understand that in other embodiments, the distance between two adjacent triangular nails 260 among the plurality of triangular nails 260 arranged at intervals on the first wide side edge 211 of the upper frame body 210 can also be 30 mm, 50 mm, 100 mm, 200 mm, 250 mm, 300 mm, etc.

[0080] It is easy to understand that when the upper sheet material 14 is placed on the upper frame body 210, a part of the first edge 141 ( Figure 2 as shown) of the upper sheet material 14 overlaps with the first wide side edge 211 of the upper frame body 210, and the second edge 142 ( Figure 2A part of the (as shown) overlaps with the first long-side edge 212 of the upper frame body 210, so that the triangular nail 260 located on the first wide-side edge 211 pierces the first edge 141 of the upper sheet material 14 above it, and the round nail 250 located on the first long-side edge 212 pierces the second edge 142 of the upper sheet material 14 above it, to fix the upper sheet material 14 to the upper frame body 210.

[0081] Reference Figure 4 、 Figure 9 and Figure 10 , wherein, Figure 9 shows a front view of the triangular nail 260, Figure 10 shows a schematic diagram of the orientation of the first stress relief portion 261 of the triangular nail 260 when the upper sheet material 14 is installed on the upper frame body 210. Each triangular nail 260 on the upper frame body 210 includes a first stress relief portion 261, the first stress relief portion 261 is arranged towards the outside of the upper frame body 210, and the first stress relief portion 261 is used for tearing the upper sheet material 14.

[0082] It is easy to understand that the first stress relief portion 261 is formed by the connection of the first surface 267 and the second surface 268 of the triangular nail 260. As Figure 10 shown, the first stress relief portion 261 is in a sharp-corner shape in the top view, and the angle α between the orientation V of the first stress relief portion 261 and the direction U of the upper frame body 210 towards its center is 90° to 180°. In this implementation, the direction in which the first edge 141 of the upper sheet material 14 shrinks due to heat and pressure is the direction U towards its center. That is to say, the angle α between the orientation V of the first stress relief portion 261 of the triangular nail 260 on the first wide-side edge 211 of the upper frame body 210 and the shrinkage direction U of the first edge 141 of the upper sheet material 14 here is 90° to 180°.

[0083] As Figure 11 shown, Figure 11It shows that the included angle α between the orientation V of the first stress relief portion 261 and the direction U in which the first edge 141 of the upper sheet 14 contracts due to heat and pressure is 180°. In this embodiment, after the upper frame 210 enters the hot pressing device 300, the first edge 141 of the upper sheet 14 on the upper frame 210 generates a stress that contracts towards its center due to heat and pressure. Then, during the hot pressing and welding process, the first edge 141 of the upper sheet 14 receives a contraction resistance along the V direction at the first stress relief portion 261. The V direction is the reverse of the direction U in which the first edge 141 of the upper sheet 14 contracts due to heat and pressure. When the contraction stress of the upper sheet 14 increases, the contraction resistance in the V direction also increases. When the contraction resistance reaches a certain value, the first stress relief portion 261 exerts a cutting effect on the first edge 141 of the upper sheet 14, and then the first edge 141 of the upper sheet 14 is torn, so that the upper sheet 14 can contract towards the center, reducing the stress at the first edge 141 of the upper sheet 14, that is, reducing the stress at the edge of the first wall 11 of the final finished TPU mattress.

[0084] Those skilled in the art can understand that the above embodiment is described by taking the included angle α between the orientation V of the first stress relief portion 261 and the direction U in which the first edge 141 of the upper sheet 14 contracts due to heat and pressure as 180° as an example. However, in other embodiments, the included angle α between the orientation V of the first stress relief portion 261 and the direction U in which the first edge 141 of the upper sheet 14 contracts due to heat and pressure can also be selected as other values, such as 120°, 140°, 150°, 160°, 170°, and so on.

[0085] Reference Figure 4 , the above-mentioned second fixing members 240 also each include a plurality of round nails 250 and a plurality of triangular nails 260.

[0086] The lower frame 220 includes two second long edges 222 and two second wide edges 221. The second long edges 222 extend along the length direction Y of the lower frame 220, and the second wide edges 221 extend along the width direction X of the lower frame 220. Each second wide edge 221 is connected to the second long edge 222 to form a rectangular lower frame 220.

[0087] Each second long edge 222 of the lower frame 220 is provided with a plurality of round nails 250, and the plurality of round nails 250 on each second long edge 222 are spaced along the length direction Y of the lower frame 220.

[0088] The distance between any two adjacent round nails 250 described above is between 30 mm and 300 mm. In this embodiment, the distance between two adjacent round nails 250 among the multiple round nails 250 spacedly arranged on the second long side edge 222 of the lower frame body 220 is 150 mm. However, those skilled in the art can understand that in other embodiments, the distance between two adjacent round nails 250 among the multiple round nails 250 spacedly arranged on the second long side edge 222 of the lower frame body 220 can also be 30 mm, 50 mm, 100 mm, 200 mm, 250 mm, 300 mm, and so on.

[0089] A plurality of triangular nails 260 are provided on each of the second wide side edges 221 of the lower frame body 220, and the plurality of triangular nails 260 on each second wide side edge 221 are spacedly arranged along the width direction X of the lower frame body 220.

[0090] The distance between any two adjacent triangular nails 260 is between 30 mm and 300 mm. In this embodiment, the distance between two adjacent triangular nails 260 among the multiple triangular nails 260 spacedly arranged on the second wide side edge 221 of the lower frame body 220 is 113.5 mm. However, those skilled in the art can understand that in other embodiments, the distance between two adjacent triangular nails 260 among the multiple triangular nails 260 spacedly arranged on the second wide side edge 221 of the lower frame body 220 can also be 30 mm, 50 mm, 100 mm, 200 mm, 250 mm, 300 mm, and so on.

[0091] It is easy to understand that, as Figure 4 , Figure 7 , Figure 12 shown, when the lower sheet 15 is placed on the lower frame body 220, a part of the third edge 151 ( Figure 2 shown) of the lower sheet 15 overlaps with the second wide side edge 221 of the lower frame body 220, and a part of the fourth edge 152 ( Figure 2 shown) of the lower sheet 15 overlaps with the second long side edge 222 of the lower frame body 220, so that the triangular nails 260 located on the second wide side edge 221 pierce the third edge 151 of the lower sheet 15 above them, and the round nails 250 located on the second long side edge 222 pierce the fourth edge 152 of the lower sheet 15 above them, so as to fix the lower sheet 15 on the lower frame body 220.

[0092] In this embodiment, each triangular nail 260 on the lower frame body 220 includes a second stress release portion 262, and the second stress release portion 262 is arranged towards the outside of the lower frame body 220.

[0093] It is easy to understand that, as Figure 12As shown, the second stress relief portion 262 is pointed in a top-down view, and the angle α between the orientation V of the second stress relief portion 262 and the direction U of the lower frame 220 towards its center is 90° to 180°. In this embodiment, the direction in which the third edge 151 of the lower sheet 15 contracts due to heat and pressure is the direction U towards its center. That is to say, the angle α between the orientation V of the second stress relief portion 262 of the triangular nail 260 on the second wide edge 221 of the lower frame 210 and the contraction direction U of the third edge 151 of the lower sheet 15 is 90° to 180°.

[0094] As Figure 13 shown, Figure 13 It shows that the angle α between the orientation V of the second stress relief portion 262 and the contraction direction U of the third edge 151 of the lower sheet 15 due to heat and pressure is 180°. In this embodiment, after the lower frame 220 enters the hot pressing device 300, the third edge 151 of the lower sheet 15 on the lower frame 220 is stressed to contract towards its center due to heat and pressure. During the hot pressing and welding process, the third edge 151 of the lower sheet 15 is subjected to a contraction resistance along the V direction at the second stress relief portion 262. The V direction is the reverse of the contraction direction U of the third edge 151 of the lower sheet 15 due to heat and pressure. When the contraction stress of the lower sheet 15 increases, the contraction resistance in the V direction also increases accordingly. When the contraction resistance reaches a certain value, the second stress relief portion 262 exerts a cutting effect on the third edge 151 of the lower sheet 15, and then the lower sheet 15 can contract towards the center, reducing the stress at the third edge 151 of the lower sheet 15.

[0095] Those skilled in the art can understand that the above embodiment is described by taking the angle α between the orientation V of the second stress relief portion 262 and the contraction direction U of the third edge 151 of the lower sheet 15 due to heat and pressure as 180° as an example. However, in other embodiments, the angle α between the orientation V of the second stress relief portion 262 and the contraction direction U of the third edge 151 of the lower sheet 15 due to heat and pressure can also be selected as other values, such as 120°, 140°, 150°, 160°, 170°, etc.

[0096] It is easy to understand that the tearing and contraction of the upper sheet 14 and the lower sheet 15 described above occur simultaneously in the hot pressing device 300. Thus, the combination of the two reduces the stress at the edges caused by hot pressing and welding during the production of the TPU mattress 10, effectively avoiding the situation where the first wall 11 and the second wall 12 of the finished TPU mattress 10 crack at both ends in the length direction Y due to excessive stress, or even the separation of the first wall 11 and the second wall 12.

[0097] Adopting the above technical solution, referring to Figures 4 to 8, place the upper frame 210 and the lower frame 220 separately, and make both the triangular nails 260 and the round nails 250 face upward. Place the upper sheet material 14 on the upper frame 210, and make the triangular nails 260 on the upper frame 210 pierce through the first edge 141 of the upper sheet material 14, and the round nails 250 on the upper frame 210 pierce through the second edge 142 of the upper sheet material 14, so as to fix the upper sheet material 14 on the upper frame 210. Similarly, place the lower sheet material 15 on the lower frame 220, and make the triangular nails 260 on the lower frame 220 pierce through the third edge 151 of the lower sheet material 15, and the round nails 250 pierce through the fourth edge 152 of the lower sheet material 15, so as to fix the lower sheet material 15 on the lower frame 220. Then place the filling layer 13 on the lower sheet material 15, and then place the upper frame 210 on the lower frame 220, and make the upper frame 210 and the lower frame 220 be arranged oppositely, and the filling layer 13 is located between the upper sheet material 14 and the lower sheet material 15.

[0098] Next, refer to Figure 3 , Figure 4 , Figure 10 and Figure 12 , and put the upper frame 210 and the lower frame 220 that are stacked together and arranged oppositely into the hot pressing device 300. The hot pressing device 300 performs hot pressing and welding on the upper sheet material 14, the lower sheet material 15, and the filling layer 13 located between the upper sheet material 14 and the lower sheet material 15. During the hot pressing and welding process, the first edge 141 of the upper sheet material 14 receives a contraction resistance along the V direction at the first stress release portion 261. The V direction is the reverse of the direction U in which the first edge 141 of the upper sheet material 14 contracts due to heat and pressure. When the contraction stress of the upper sheet material 14 increases, the contraction resistance in the V direction also increases. When the contraction resistance reaches a certain value, the first stress release portion 261 exerts a cutting effect on the first edge 141 of the upper sheet material 14, and then the first edge 141 of the upper sheet material 14 is torn, so that the upper sheet material 14 can contract towards the center to reduce the stress at the first edge 141 of the upper sheet material 14.

[0099] Similarly, the third edge 151 of the lower sheet material 15 receives a contraction resistance along the V direction at the second stress release portion 262. The V direction is the reverse of the direction U in which the third edge 151 of the lower sheet material 15 contracts due to heat and pressure. When the contraction stress of the lower sheet material 15 increases, the contraction resistance in the V direction also increases. When the contraction resistance reaches a certain value, the second stress release portion 262 exerts a cutting effect on the third edge 151 of the lower sheet material 15, and then the third edge 151 of the lower sheet material 15 is torn, so that the lower sheet material 15 can contract towards the center to reduce the stress at the third edge 151 of the lower sheet material 15.

[0100] In summary, in the present application, by providing the first stress relief portion 261, the stress at the first edge 141 of the upper sheet 14 is reduced, and by providing the second stress relief portion 262, the stress at the third edge 151 of the lower sheet 15 is reduced. Thus, the stress at the edges at both ends in the length direction Y of the TPU mattress 10 caused during the production process is reduced, effectively avoiding the cracking of the first wall 11 and the second wall 12 of the finished TPU mattress 10 at the edges at both ends in its length direction Y due to excessive stress, and even avoiding the separation of the first wall 11 and the second wall 12.

[0101] After the hot pressing and welding are completed, the upper frame 210 and the lower frame 220 are sent out of the hot pressing device 300 together, and the operator separates the TPU mattress 10 from the upper frame 210 and the lower frame 220.

[0102] In this embodiment, the upper frame 210 and the lower frame 220 have the same structure, and the first fixing member 230 and the second fixing member 240 have the same structure. However, those skilled in the art can understand that in other embodiments, the upper frame 210 and the lower frame 220 with different structures, as well as the first fixing member 230 and the second fixing member 240, can also be provided.

[0103] Reference Figure 4 and Figure 9 , each triangular nail 260 includes a second bottom portion 263, a second middle portion 264, and a second top portion 265 that are connected in sequence.

[0104] The second bottom portion 263 of each triangular nail 260 on the upper frame 210 is fixed to the upper frame 210, and the second bottom portion 263 of each triangular nail 260 on the lower frame 220 is fixed to the lower frame 220.

[0105] In this embodiment, the second bottom portion 263 includes a second threaded portion 266. Threaded holes (not shown in the figure) are provided on the upper frame 210 and the lower frame 220. The second threaded portion 266 of the second bottom portion 263 is inserted into the threaded hole and is threadedly connected thereto. Those skilled in the art can understand that in other embodiments, the connection between the second bottom portion 263 of the triangular nail 260 and the upper frame 210 and the lower frame 220 can also be achieved in other ways. For example, the second bottom portion 263 is welded to the surfaces of the upper frame 210 and the lower frame 220.

[0106] The second top portion 265 is spiked. It is easy to understand that the spiked second top portion 265 is more likely to pierce through the upper sheet 14 and the lower sheet 15 to fix the upper sheet 14 to the upper frame 210 and fix the lower sheet 15 to the lower frame 220.

[0107] The second intermediate portion 264 of the triangular nail 260 on the upper frame body 210 includes a first stress relief portion 261, and the second intermediate portion 264 of the triangular nail 260 on the lower frame body 220 includes a second stress relief portion 262. The cross-sections of both the first stress relief portion 261 and the second stress relief portion 262 are in a sharp-angled shape, as Figure 10 shown, and the sharp angle is formed by the intersection of the first surface 267 and the second surface 268.

[0108] As Figure 9 shown, the overall length H1 of the triangular nail 260 is 5 mm to 40 mm. In this embodiment, the overall length H1 of the triangular nail 260 is 24 mm. Those skilled in the art can understand that in other embodiments, the overall length H1 of the triangular nail 260 can also be set according to actual needs. For example, the overall length H1 of the triangular nail 260 can also be 5 mm, 10 mm, 20 mm, 30 mm, 40 mm, and so on.

[0109] Correspondingly, as Figure 9 shown, in this embodiment, the total length h1 of the second intermediate portion 264 and the second top portion 265 is 15 mm. The nominal diameter M1 of the second thread portion 266 of the second bottom portion 263 is 5 mm. Those skilled in the art can understand that in other embodiments, the total length h1 of the second intermediate portion 264 and the second top portion 265, and the nominal diameter M1 of the second thread portion 266 of the second bottom portion 263 can both be set according to actual needs, and this application does not limit this.

[0110] Referring to Figure 4 and Figure 14 , each of the above-mentioned round nails 250 includes a first bottom portion 251, a first intermediate portion 252, and a first top portion 253 that are connected in sequence.

[0111] The first bottom portion 251 of each round nail 250 on the upper frame body 210 is fixed to the upper frame body 210, and the first bottom portion 251 of each round nail 250 on the lower frame body 220 is fixed to the lower frame body 220. In this embodiment, the first bottom portion 251 includes a first thread portion 254, and the upper frame body 210 and the lower frame body 220 are provided with threaded holes (not shown in the figure). The first thread portion 254 of the first bottom portion 251 is inserted into the threaded hole and is threadedly connected thereto.

[0112] Those skilled in the art can understand that in other embodiments, the connection between the first bottom portion 251 of the round nail 250 and the upper frame body 210 and the lower frame body 220 can also be achieved by other means. For example, the first bottom portion 251 of the round nail 250 on the upper frame body 210 is directly welded to the surface of the upper frame body 210, and the first bottom portion 251 of the round nail 250 on the lower frame body 220 is directly welded to the surface of the lower frame body 220.

[0113] The first intermediate portion 252 is vertically connected to the first bottom portion 251. The first intermediate portion 252 extends along the height direction Z, and the cross-section of the first intermediate portion 252 is circular. That is, the first intermediate portion 252 of the round nail 250 is cylindrical.

[0114] The first top portion 253 is spiky. It is easy to understand that the spiky first top portion 253 is more likely to pierce through the upper sheet material 14 and the lower sheet material 15 to fix the upper sheet material 14 to the upper frame body 210 and fix the lower sheet material 15 to the lower frame body 220.

[0115] As Figure 14 shown, the overall length H2 of the round nail 250 is 5 mm to 40 mm. In this embodiment, the overall length H2 of the round nail 250 is 24 mm. Those skilled in the art can understand that in other embodiments, the overall length H2 of the round nail 250 can also be set according to actual needs. For example, the overall length H2 of the round nail 250 can also be 5 mm, 10 mm, 20 mm, 30 mm, 40 mm, etc.

[0116] Correspondingly, as Figure 14 shown, in this embodiment, the total length h2 of the first intermediate portion 252 and the first top portion 253 is 15 mm. The radial dimension D2 of the first intermediate portion 252 is 2 mm. The nominal diameter M2 of the first threaded portion 254 is 4 mm. Those skilled in the art can understand that in other embodiments, the total length h2 of the first intermediate portion 252 and the first top portion 253, the radial dimension D2 of the first intermediate portion 252, and the nominal diameter M2 of the first threaded portion 254 can all be set according to actual needs, and this application does not limit this.

[0117] As Figure 4 , Figure 15 and Figure 16 shown, two first handles 213 are provided on both first wide-edge edges 211 of the upper frame body 210, and the two first handles 213 are spaced apart in the width direction X of the upper frame body 210. Two second handles 223 are provided on both second wide-edge edges 221 of the lower frame body 220, and the two second handles 223 are spaced apart in the width direction X of the lower frame body 220.

[0118] In this embodiment, both the first handle 213 and the second handle 223 are rectangular, which is convenient for the operator to hold the first handle 213 to move the upper frame body 210, thereby facilitating the assembly of the upper sheet material 14, the lower sheet material 15, and the filling layer 13 before hot press welding. And after the hot press welding is completed, hold the first handle 213 to pick up the upper frame body 210 to separate it from the lower frame body 220. The TPU mattress 10 is separated from the lower frame body 220 together with the upper frame body 210. Then the operator separates the TPU mattress 10 from the upper frame body 210, that is, it is convenient to transfer the finished TPU mattress 10.

[0119] Reference Figure 4 、 Figure 15 、 Figure 16 Figure 16 , the loading device 200 further includes a moving frame 270. The lower frame 220 is located on the moving frame 270 and fixedly connected to the moving frame 270. Limit slots 271 are provided at both ends of the moving frame 270 in the length direction Y. Two limit slots 271 are provided at each end of the moving frame 270 in the length direction Y. The second handle 223 is embedded in the limit slots 271 to limit the relative position of the lower frame 220.

[0120] In this embodiment, the second handle 223 is embedded in the limit slots 271, and the lower frame 220 is fixedly connected to the moving frame 270 to limit the displacement of the lower frame 220 relative to the moving frame 270. During the movement of the moving frame 270 and during the welding process, the position of the lower frame 220 is stable.

[0121] Since the lower frame 220 is fixedly connected to the moving frame 270, the lower frame 220 is fixed relative to the moving frame 270. During the actual operation process, the operator directly fixes the lower sheet 15 on the lower frame 220 through the triangular nails 260 and round nails 250. The upper sheet 14 is fixed on the upper frame 210. Then, the operator picks up the upper frame 210 by the first handle 213 and places it on the lower frame 220, and places the two relatively. For the TPU mattress 10 that has completed hot pressing and welding, the operator can hold the first handle 213 and at the same time clamp the edges of the upper sheet 14 and the lower sheet 15, lift the TPU mattress 10 and the upper frame 210, so that the TPU mattress 10 on the upper frame 210 is separated from the lower frame 220, and finally the TPU mattress 10 and the upper frame 210 are separated. During this process, there is no need to move the position of the lower frame 220, thereby improving production efficiency.

[0122] The above-mentioned moving frame 270 is used to enter and exit the hot pressing device 300 along the width direction X of the lower frame 220. Specifically, the moving frame 270 is used to place the upper frame 210 and the lower frame 220, as well as the upper sheet 14 on the upper frame 210, the lower sheet 15 on the lower frame 220, and the filling layer 13. The moving frame 270 enters and exits the hot pressing device 300 along the width direction X of the lower frame 220 to feed the placed upper sheet 14, lower sheet 15, and filling layer 13 into the hot pressing device 300 for hot pressing and welding, or to send out the TPU mattress 10 that has completed hot pressing and welding.

[0123] Reference Figure 3 、 Figure 15 、 Figure 17 and Figure 18 , wherein, Figure 17The hot pressing device is not shown. A sliding component 400 and a driving component 500 are arranged below the moving frame 270. Among them, the sliding component 400 includes a slide rail 410 and a pulley 420. The slide rail 410 extends along the width direction X of the lower frame body 220 to the hot pressing device 300. The driving component 500 is used to drive the moving frame 270 to slide along the slide rail 410 towards the hot pressing device 300.

[0124] Specifically, the driving component 500 includes a motor 510, a first connecting rod 520, a second connecting rod 530, a slider 540, and a third connecting rod 550. Among them, the motor 510 is connected to the first connecting rod 520, and the motor 510 is used to drive the first connecting rod 520 to rotate in the horizontal plane; the lower end of the second connecting rod 530 is connected to the first connecting rod 520, and the upper end of the second connecting rod 530 is connected to the slider 540; the slider 540 is sleeved on the third connecting rod 550, and the slider 540 can slide on the third connecting rod 550 along the extending direction of the third connecting rod 550; both ends of the third connecting rod 550 are connected to the moving frame 270.

[0125] Then start the motor 510. The motor 510 drives the first connecting rod 520 to rotate forward (for example, clockwise, Figure 17 as shown by the R direction) in the horizontal plane. The driving force of the motor 510 is transmitted to the slider 540 through the first connecting rod 520 and the second connecting rod 530, so that the slider 540 drives the third connecting rod 550 to move towards the hot pressing device 300 along the width direction X of the lower frame body 220, and the moving frame 270 slides on the slide rail 410 towards the hot pressing device 300. When the first connecting rod 520 rotates forward 180°, the moving frame 270 enters the hot pressing device 300 to perform hot pressing welding operation. Correspondingly, after the hot pressing device 300 completes the hot pressing welding, the motor 510 drives the first connecting rod 520 to rotate backward (for example, counterclockwise), and the moving frame 270 slides out of the hot pressing device 300 on the slide rail 410. When the first connecting rod 520 rotates backward 180°, the moving frame 270 returns to the initial position.

[0126] Those skilled in the art can understand that in other embodiments, other driving components 500 can also be selected, such as air cylinders, etc., to realize the movement of the moving frame 270.

[0127] It is easy to understand that in this embodiment, two loading devices 200 are provided. The slide rail 410 extends from one of the loading devices 200 along the width direction X of the lower frame body 220 to the other loading device 200. Then, the moving frames 270 of the two loading devices 200 can both enter the hot pressing device 300 located between the two loading devices 200 along the slide rail 410 to perform hot pressing welding.

[0128] Embodiment 2

[0129] Refer to Figure 4 、 Figure 19 andFigure 20 Triangular nails 260 are all arranged on the first wide-side edge 211 and the first long-side edge 212 of the upper frame body 210, and on the second wide-side edge 221 and the second long-side edge 222 of the lower frame body 220. The multiple triangular nails 260 on each edge are arranged at intervals; each triangular nail 260 on the upper frame body 210 includes a first stress relief portion 261; each triangular nail 260 on the lower frame body 220 includes a second stress relief portion 262.

[0130] As Figure 19 and Figure 20 shown, the angle α between the orientation N of the first stress relief portion 261 of the triangular nail 260 on the first long-side edge 212 of the upper frame body 210 and the direction M of the upper frame body 210 towards the center is 90° to 180°. The angle α between the orientation N of the second stress relief portion 262 of the triangular nail 260 on the second long-side edge 222 of the lower frame body 220 and the direction M of the lower frame body 220 towards the center is 90° to 180°. The angle α between the orientation V of the first stress relief portion 261 of the triangular nail 260 on the first wide-side edge 211 of the upper frame body 210 and the direction U of the upper frame body 210 towards the center is 90° to 180°. The angle α between the orientation V of the second stress relief portion 262 of the triangular nail 260 on the second wide-side edge 221 of the lower frame body 220 and the direction U of the lower frame body 220 towards the center is 90° to 180°.

[0131] Then, the two second edges 142 of the upper sheet 14 are subjected to a contraction resistance along the N direction at the first stress relief portion 261 of the triangular nail 260 on the first long-side edge 212. When the contraction stress of the upper sheet 14 increases, the contraction resistance in the N direction also increases. When the contraction resistance reaches a certain value, the first stress relief portion 261 exerts a cutting effect on the second edge 142 of the upper sheet 14, thereby forming tears at the two second edges 142 of the upper sheet 14. Similarly, the two fourth edges 152 of the lower sheet 15 are subjected to a contraction resistance along the N direction at the second stress relief portion 262 of the triangular nail 260 on the second long-side edge 222. When the contraction stress of the lower sheet 15 increases, the contraction resistance in the N direction also increases. When the contraction resistance reaches a certain value, the second stress relief portion 262 exerts a cutting effect on the fourth edge 152 of the lower sheet 15, thereby forming tears at the two fourth edges 152 of the lower sheet 15, thus reducing the stress magnitude at the two end edges of the TPU mattress 10 in its width direction X after hot press welding, effectively avoiding the situation that the finished TPU mattress 10 cracks due to excessive stress at the two end edges in its width direction X, and even causing the separation of the first wall 11 and the second wall 12.

[0132] Accordingly, the two first edges 141 of the upper sheet 14 are subject to a contraction resistance in the V direction at the first stress release portion 261 of the triangular nail 260 located on the first wide edge 211. When the contraction stress of the upper sheet 14 increases, the contraction resistance in the V direction also increases. When the contraction resistance reaches a certain value, the first stress release portion 261 cuts the first edge 141 of the upper sheet 14, and then tears are formed at the two first edges 141 of the upper sheet 14. Similarly, the two third edges 151 of the lower sheet 15 are subject to a contraction resistance in the V direction at the second stress release portion 262 of the triangular nail 260 located on the second wide edge 221. When the contraction stress of the lower sheet 15 increases, the contraction resistance in the V direction also increases. When the contraction resistance reaches a certain value, the second stress release portion 262 cuts the third edge 151 of the lower sheet 15, and then tears are formed at the two third edges 151 of the lower sheet 15, thereby reducing the stress at the two end edges of the TPU mattress 10 in its length direction Y after thermocompression welding is completed, effectively avoiding the cracking of the finished TPU mattress 10 at the two end edges in its length direction Y due to excessive stress, and even avoiding the separation of the first wall 11 and the second wall 12.

[0133] In summary, in this embodiment, tears are formed at the 4 edges of the upper sheet 14 and the lower sheet 15, thereby reducing the stress on the TPU mattress 10 as a whole after thermocompression welding is completed, effectively avoiding the cracking of the four peripheral edges of the finished TPU mattress 10 due to excessive stress, and even avoiding the separation of the first wall 11 and the second wall 12.

[0134] Those skilled in the art can understand that in other embodiments, a plurality of triangular nails 260 and a plurality of round nails 250 can be arranged at intervals on the first long edge 212 of the upper frame 210. Similarly, a plurality of triangular nails 260 and a plurality of round nails 250 can also be arranged at intervals on the second long edge 222 of the lower frame 220.

[0135] Optionally, a plurality of triangular nails 260 and a plurality of round nails 250 can also be arranged at intervals on the first wide edge 211 of the upper frame 210.
