[0027] In this embodiment, the conveying assembly and the roller assembly are distributed vertically, combined with... Figure 1 , 4 As shown, the extruded board 101 and aluminum foil 102, which are conveyed separately, can stick together and press into the pressing area below the hot roller assembly during the forward conveying process, thus realizing the pressing process between the two.

[0028] Before pressing, the unwinding preheating assembly, located on the winding roller component, combines... Figure 4 The aluminum foil 102 can be continuously and smoothly fed into the pressing area. Combined with the conveying components, the extrusion board 101 and the aluminum foil 102 are aligned, thereby improving the pressing effect. At the same time, the preheating component placed in front of the roller component can preheat the aluminum foil 102, so that the aluminum foil 102 can quickly reach the appropriate pressing stability and improve the bonding effect.

[0029] The hot roller assembly in this device uses a hot pressing process to tightly bond the extruded polystyrene board 101 and the aluminum foil 102, forming a composite material with excellent heat insulation, waterproof and fireproof properties. At the same time, the roller assembly and conveying assembly can smoothly transport the extruded polystyrene board 101 and the aluminum foil 102 to the pressing area and align them to ensure the pressing effect. The preheating component can preheat the aluminum foil 102, so that the aluminum foil 102 can quickly reach the appropriate pressing stability and improve the bonding effect.

[0030] Furthermore, the conveying assembly includes two sets of conveyor belt structures and a plurality of support bars 113 disposed between the two sets of conveyor belt structures. Adjacent support bars 113 are in close contact and form a conveying support surface for the extruded board 101. Each set of conveyor belt structures includes two conveying rollers 112 rotatably mounted on the seat frame 111 and a support bar 113 disposed between the two conveying rollers 112. It also includes a motor assembly 114 disposed on the side wall of the seat frame 111, and the motor output end disposed in the motor assembly 114 passes through a through hole opened in the side wall of the seat frame 111 and is fixedly connected to one of the conveying rollers 112.

[0031] It is worth noting here that, in conjunction with Figure 1 , 2 As shown in Figures 3 and 4, several support bars 113 together constitute a conveying support surface for the extruded board 101, which takes into account both flexible transmission and rigid support functions. The continuous transmission process of the support bars 113 can be realized by controlling the motor assembly 114.

[0032] Example 2

[0033] In another embodiment of this utility model, the hot roller assembly includes a mounting frame 211 fixed in the middle of the seat frame 111. The mounting frame 211 has several cylinders 212 at its top, and mounting plates 213 are fixed to the telescopic ends of the cylinders 212. Several transmission components are also provided on both sides of the lower surface of the mounting plate 213. Each transmission component includes an inverted U-shaped frame 214, a slider 215 slidably mounted to the inverted U-shaped frame 214, and a spring 216 disposed between the slider 215 and the top of the inverted U-shaped frame 214.

[0034] In this embodiment, as shown in 3, 4, 5, and 6, the mounting plate 213 is fixed to the telescopic end of several cylinders 212, thus its height can be adjusted to accommodate extruded boards 101 and aluminum foil 102 of different thicknesses. Several inverted U-shaped frames 214 are respectively provided on both sides of the mounting plate 213, and sliders 215 are provided in them. Each slider 215 is provided with a branch pipe 217. First, the rollers 218 connected by two oppositely distributed branch pipes 217 are used for hot roller pressing. The meshing transmission component provided on one side of the branch pipe 217 can realize the synchronous rotation of several rollers 218. At the same time, the hot air generating component can realize the synchronous heating process of several rollers 218, ensuring the rolling effect. Therefore, when the extruded board 101 and aluminum foil 102 are placed together in the pressing area, the several rollers 218 and the mounting plate 213 can clamp the extruded board 101 and aluminum foil 102 in the middle to realize the tight pressing process.

[0035] The slider 215 and spring 216 further enhance the pressing strength when the roller 218 contacts the extruded board 101 and aluminum foil 102.

[0036] Furthermore, the mounting frame 211 is provided with curtains 219 at both ends of the mounting plate 213.

[0037] Combination Figure 4 As shown, the curtain 219 here can be a soft hanging curtain, which makes it easy to open the mounting frame 211 to repair its internal structure, without hindering the conveying of the extruded board 101 and aluminum foil 102, and also reduces temperature loss.

[0038] Furthermore, the meshing transmission assembly includes a connecting frame 611 fixed on the first and second sliders 215, a first motor 612 is provided in the connecting frame 611, and a drive tooth 613 fixed to the output end of the first motor 612. The drive tooth 613 is fixed to the first and second branch tube 217.

[0039] Combination Figure 2 , 6 As shown, the first branch pipe 217 is fixed to the drive tooth 613, while the other branch pipes 217 are fixed to the transmission tooth 614. At the same time, both the drive tooth 613 and the transmission tooth 614 mesh with the inner toothed belt 615. Therefore, when the connecting frame 611 is driven, it can drive several branch pipes 217 to rotate synchronously.

[0040] Furthermore, the heat generation assembly includes a heat transfer structure and a heat return structure distributed on both sides of the mounting frame 211; wherein, the heat transfer structure includes a first pipe fitting, a heating box 313 located at the top of the mounting frame 211 and connected to the first pipe section; the first pipe fitting includes a pipe body 311, a plurality of first connecting pipes connected to the pipe body 311, the plurality of first connecting pipes being rotatably installed and connected to a plurality of branch pipes 217; and a second connecting pipe 312 located on and connected to the pipe body 311, with one end of the second connecting pipe 312 away from the pipe body 311 connected to the heating box 313; furthermore, the heat return structure includes a second pipe fitting with the same structure as the first pipe fitting, and a recovery box 314 located on the mounting frame 211 and connected to the second pipe fitting, the recovery box 314 being connected to the heating box 313 for the recycling of heat.

[0041] Combination Figure 2 , 6 As shown, one side of the tube body 311 is rotatably installed with several first connecting pipes and several branch pipes 217, while the second connecting pipe 312 above it is connected to the heating box 313. When the impeller inside the heating box 313 runs, hot air can pass through the second connecting pipe 312, the tube body 311, and the branch pipes 217 into the roller 218. At this time, the heat recovery component on the other side of the roller 218 can collect the cooled gas, reheat it, and recycle it.

[0042] Furthermore, a rotary sealing plug is provided between each branch pipe 217 and its corresponding first connecting pipe, combined with... Figure 6 As shown, this ensures a tight seal when the two rotate.

[0043] Furthermore, the roller assembly includes a mounting shell 411 fixed to one side of the mounting frame 211, and a roller body 412 rotatably mounted on the mounting shell 411 for winding and unwinding the aluminum foil 102; it also includes a second motor 413 disposed on the mounting shell 411, the output end of the second motor 413 being fixed to the roller body 412 and used as a drive source for rotating the roller body 412.

[0044] Combination Figure 4 , 5 As shown, when the second motor 413 is controlled to rotate, the roller body 412 can rotate forward and reverse, thereby realizing the winding and unwinding process of the aluminum foil 102.

[0045] Example 3

[0046] In another embodiment of this utility model, the preheating component includes two preheating boxes 511 disposed on both sides of the middle part of the mounting shell 411, and a preheating frame 512 symmetrically fixed between and connected to the two preheating boxes 511, with an oblique gap between the two preheating frames 512 for the aluminum foil 102 to pass through; it also includes two circulation boxes 514 fixed on both sides of the mounting frame 211 and connected to the mounting frame 211, and the conduits 513 connected to the ends of the two circulation boxes 514 are respectively connected to the two preheating boxes 511.

[0047] Combination Figure 3 , 5 As shown, it is worth noting that the two preheating boxes 511 are connected to the mounting frame 211 via two conduits 513 and two circulation boxes 514, respectively. A pump body is installed inside the circulation box 514, and inclined gaps are left in the two preheating frames 512. (See reference...) Figure 4 This allows the aluminum foil 102 to pass through. When the preheating operation is performed using the heat of the mounting frame 211, the aluminum foil 102 is passed through the oblique gap. Heat can then be transferred from the two preheating frames 512 to both sides of the aluminum foil 102. As a result, the preheated aluminum foil 102 can quickly reach the appropriate pressing temperature under the action of several rollers 218, ensuring the pressing effect.
