[0056] The structure of the compression roller assembly 34 will be described in detail.
[0057] Optionally, the number of the compression roller assembly 34 is two or more, and the at least two compression roller assemblies 34 include a first compression roller assembly 341 and a second compression roller assembly 342.

The first compression roller assembly 341 is arranged on the upstream side of the second compression roller assembly 342, and the roll gap of the first compression roller assembly 341 is greater than or equal to the roll gap of the second compression roller assembly 342.
[0058] The roll gap of the first compression roller assembly 341 refers to the gap between the two oppositely arranged compression roller elements of the first compression roller assembly 341 during rolling. The roll gap of the second compression roller assembly 342 refers to the gap between the two oppositely arranged compression roller elements of the second compression roller assembly 342 during rolling.

The thickness of the core material 201 is the size of the core material 201 along the Z-Z direction. Figure 4
[0059] It should be noted that the core material 201 is not only dried but also rolled by the roller assembly 34 for multiple times during the process of entering into the installation space 311 from the feeding port 312 and going out from the discharging port 313, so that the core material 201 can become a core material 201 with a specified thickness, and the rolled core material 201 has better surface flatness.
[0060] It can be understood that the second roller assembly 342 herein can also be replaced by a similar structure, for example, two plate-shaped structures arranged oppositely, so as to change the thickness of the core material 201 by extrusion of the two plate-shaped structures and improve the surface flatness of the core material 201.
[0061] Optionally, as shown in Figure 4 and Figure 5 The first roller assembly 341 includes first and second roller members 3411 and 3412 arranged oppositely, and the first and second roller members 3411 and 3412 are respectively arranged on opposite sides of the first transmission belt 321. The second roller assembly 342 includes third and fourth roller members 3421 and 3422 arranged oppositely, and the third and fourth roller members 3421 and 3422 are respectively arranged on opposite sides of the second transmission belt 351. The rolling gap between the first and second roller members 3411 and 3412 is greater than or equal to the rolling gap between the third and fourth roller members 3421 and 3422.
[0062] The first roller assembly 341 is located on the upstream side of the second roller assembly 342, so that the rolling gap between the first and second roller members 3411 and 3412 is greater than or equal to the rolling gap between the third and fourth roller members 3421 and 3422, so as to realize the effect of continuous rolling of the core material 201 and control the thickness of the core material 201.
[0063] Optionally, the number of the first roller members 3411 can be two or more, and the two or more first roller members 3411 are arranged at intervals along the X-X direction. Correspondingly, the number of the second roller members 3412 can be two or more, and the two or more second roller members 3412 are arranged at intervals along the X-X direction. Each first roller member 3411 is arranged opposite to a corresponding second roller member 3412, so that the first roller assembly 341 can roll the core material 201 for multiple times.
[0064] It can be understood that the number of third roller elements 3421 can be two or more, and the two or more third roller elements 3421 are arranged in intervals along the X-X direction. Correspondingly, the number of fourth roller elements 3422 can be two or more, and the two or more fourth roller elements 3422 are arranged in intervals along the X-X direction, and each third roller element 3421 is arranged in correspondence with a corresponding fourth roller element 3422, so that the second roller assembly 342 can roll the core material 201 multiple times.
[0065] In the case of Figure 5 , the number of first roller elements 3411 is two, and the number of second roller elements 3412 is also two, and the two first roller elements 3411 and the two second roller elements 3412 are arranged in correspondence, respectively. At this time, the first roller assembly 341 can roll the core material 201 twice. Figure 5 In the case of , the number of third roller elements 3421 is two, and the number of fourth roller elements 3422 is also two, and the two third roller elements 3421 and the two fourth roller elements 3422 are arranged in correspondence, respectively. At this time, the second roller assembly 342 can roll the core material 201 twice.
[0066] Optionally, the rolling gap between the first roller element 3411 and the second roller element 3412 is adjustable. Correspondingly, the rolling gap between the third roller element 3421 and the fourth roller element 3422 is adjustable.
[0067] Here, the rolling gap between the first roller element 3411 and the second roller element 3412 has multiple adjustment modes. The first mode is to adjust the position of the first roller element 3411, so that the rolling gap between the first roller element 3411 and the second roller element 3412 becomes larger or smaller. The second mode is to adjust the position of the second roller element 3412, so that the rolling gap between the first roller element 3411 and the second roller element 3412 becomes larger or smaller. The third mode is to adjust the position of the first roller element 3411 and the position of the second roller element 3412, so that the rolling gap between the first roller element 3411 and the second roller element 3412 becomes larger or smaller. Here, by adjusting the rolling gap between the first roller element 3411 and the second roller element 3412, and adjusting the rolling gap between the third roller element 3421 and the fourth roller element 3422, the hot pressing equipment 300 can be suitable for core materials 201 of multiple different thicknesses, and the use range of the hot pressing equipment 300 is improved.
[0068] Correspondingly, the roll gap between the third roller member 3421 and the fourth roller member 3422 has multiple adjustment modes, the first mode is to adjust the position of the third roller member 3421, so that the roll gap between the third roller member 3421 and the fourth roller member 3422 becomes larger or smaller; the second mode is to adjust the position of the fourth roller member 3422, so that the roll gap between the third roller member 3421 and the fourth roller member 3422 becomes larger or smaller; the third mode is to adjust the position of the third roller member 3421 and the position of the fourth roller member 3422, so that the roll gap between the third roller member 3421 and the fourth roller member 3422 becomes larger or smaller.
[0069] The specific structure of the first roller assembly 341 will be introduced below with the position of the second roller member 3412 fixed and the position of the first roller member 3411 adjustable. The specific structure of the second roller assembly 342 will be introduced below with the position of the fourth roller member 3422 fixed and the position of the third roller member 3421 adjustable.
[0070] Optionally, as shown in Figure 4 and Figure 5 The first roller assembly 341 further includes a first driving member 3413 and a first adjusting member 3414, the first driving member 3413 is drivingly connected with the first adjusting member 3414, and the first adjusting member 3414 is connected with one of the first roller member 3411 and the second roller member 3412.
[0071] The first driving member 3413 can adopt a motor, a hydraulic cylinder or a pneumatic cylinder, etc. The first adjusting member 3414 is connected with the first roller member 3411, and is moved by the first driving member 3413 to drive the first adjusting member 3414 to move, so that the first roller member 3411 connected with the first adjusting member 3414 moves along the Z-Z direction, so that the first roller member 3411 can produce the movement of approaching or moving away from the second roller member 3412.
[0072] Alternatively, the first adjusting member 3414 can also be connected with the second roller member 3412, and the movement towards or away from the second roller member 3412 is generated by driving the second roller member 3412, so as to adjust the roll gap between the first roller member 3411 and the second roller member 3412.
[0073] The first adjusting member 3414 can be an integral or separate structure. It can consist of a first connecting rod and a first mounting plate, with the connecting rod connected to the first driving member 3413 and the mounting plate. The first pressure roller 3411 is rotatably mounted on the first mounting plate. Alternatively, the first adjusting member 3414 can be formed using multiple rod-like structures. For example, the first adjusting member 3414 may include multiple first vertical rods and multiple first horizontal rods. The first pressure roller 3411 is rotatably mounted on the horizontal rods. One first vertical rod is connected to the first driving member 3413, and the other first vertical rods move the first horizontal rods during movement, thereby causing the first pressure roller 3411 to move in the ZZ direction.
[0074] Accordingly, the second pressure roller assembly 342 also includes a second drive member 3423 and a second adjustment member 3424. The second drive member 3423 is drivenly connected to the second adjustment member 3424, and the second adjustment member 3424 is connected to one of the third pressure roller assembly 3421 and the fourth pressure roller assembly 3422.
[0075] The second adjusting member 3424 can be an integral or separate structure. It can be a structure of a second connecting rod and a second mounting plate, wherein the second connecting rod is connected to the second driving member 3423 and the second mounting plate, and the third pressure roller member 3421 is rotatably mounted on the second mounting plate. Alternatively, the second adjusting member 3424 can be formed using multiple rod-like structures, such as multiple second vertical rods and multiple second horizontal rods. The third pressure roller member 3421 is rotatably mounted on the second horizontal rods. One second vertical rod is connected to the second driving member 3423, and the other second vertical rods drive the second horizontal rods to move during movement, thereby causing the third pressure roller member 3421 to move in the ZZ direction.
[0076] Alternatively, the second adjusting member 3424 can also be connected to the fourth pressure roller member 3422, thereby adjusting the roller gap between the third pressure roller member 3421 and the fourth pressure roller member 3422 by driving the fourth pressure roller member 3422 to move toward or away from the third pressure roller member 3421.
[0077] Optionally, such as Figure 1 As shown, the first conveying assembly 32 also includes at least two first tension rollers 322, and the first transmission belt 321 is wound around the first tension rollers 322.
[0078] Here, by setting at least two first tensioning rollers 322, the first transmission belt 321 can be moved in a loop by the rotation of the two first tensioning rollers 322, so that the core material 201 placed on the surface of the first transmission belt 321 can be moved from the feeding port 312 to the discharging port 313.
[0079] Optionally, as shown in Figure 4 The hot-pressing device 300 further comprises a second conveying assembly 35, which is spaced apart from the first conveying assembly 32 and arranged on the opposite side of the core material 201.
[0080] Specifically, the second conveying assembly 35 and the first conveying assembly 32 are spaced apart along the Z-Z direction and arranged on the opposite sides of the core material 201, so that the transmission of the core material 201 can be realized by the joint action of the first conveying assembly 32 and the second conveying assembly 35, thereby reducing the probability of the core material 201 being stuck.
[0081] Optionally, as shown in Figure 4 The second conveying assembly 35 comprises a second transmission belt 351 and at least two second tensioning rollers 352, and the second transmission belt 351 is arranged around the second tensioning rollers 352.
[0082] The structure of the second conveying assembly 35 is similar to that of the first conveying assembly 32, and the structure of the second conveying assembly 35 will not be described here.
[0083] It should be emphasized that the surfaces of the second transmission belt 351 and the first transmission belt 321 are both in a grid structure, which can increase the friction between the core material 201 and the first transmission belt 321 or the second transmission belt 351, so that the core material 201 can move smoothly.
[0084] Optionally, as shown in Figure 4 The hot-pressing device 300 further comprises a heating assembly 33 arranged in the mounting space 311. The heating assembly 33 can not only heat the air flow entering the mounting space 311, but also heat the compression roller assembly 34 and the core material 201 in the mounting space 311, thereby achieving drying and hot-rolling of the core material 201.
[0085] Optionally, the heating assembly 33 comprises heating elements 331, and the number of the heating elements 331 can be two or more. The heating elements 331 comprise at least one of an infrared heating element 331, an electric resistance heating element, and a microwave heating element 331.
[0086] The heating element 331 here can adopt a resistance electric heating element to heat, such as a carbon fiber light source, to heat and keep warm the installation space 311 in the hot pressing equipment 300, so that the compression roller assembly 34 and the core material 201 are both at a high working temperature. The working temperature here can be selected according to the material of the core material 201, such as about 100℃.
[0087] In Figure 4 which the number of carbon fiber light sources is two, one of which is located at the top of the installation space 311 and the other is located at the bottom of the installation space 311, so that the installation space 311 can be heated from different positions to make the temperature of the installation space 311 uniformly distributed.
[0088] Optionally, the hot pressing equipment 300 further comprises a blowing assembly 36, which is connected with the shell 31, and the air outlet of the blowing assembly 36 communicates with the installation space 311.
