However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0023] Embodiment 1

[0024] Reference Figure 1-5 As shown: a special heating plate for a hot cutting knife, including two symmetrically arranged heating main boards 9, one side of the heating main board 9 is fixedly connected with a heat insulation board 3, the heat insulation board 3 is connected with a limit bolt 1 through a threaded connection, the end of the limit bolt 1 passes through the heating main board 9, one side of the heat insulation board 3 is fixedly connected with an anti-slip strip 2, and one side of the heating main board 9 is respectively fixedly connected with a splicing strip 1 7 and a splicing strip 2 8, a snap-fit ​​groove is provided on one side of the splicing strip 2 8, and a snap-fit ​​strip 12 is fixedly connected to one side of the splicing strip 1 7.

[0025] A limiting groove 11 is provided on one side of the heating main board 9 , and a heating tube 10 is engaged in the limiting groove 11 .

[0026] A heat conducting plate 6 is clamped on one side of the heating tube 10 , and one side of the heat conducting plate 6 is fixedly connected to the heating main board 9 .

[0027] One side of the heating main board 9 is fixedly connected to a side bar 5 , and one side of the side bar 5 is fixedly connected to the heat insulation board 3 .

[0028] The use of splicing strips 1 7 and 2 8 facilitates the splicing of the heating main board 9 on both sides of the cutting knife. The limiting groove 11 engages with the heating tube 10, which facilitates the installation of the heating tube 10 between the heating main board 9 and the heat conducting plate 6. The heat conducting plate 6 is made of metal and has a good heat conduction effect after being heated by the heating tube 10, thereby avoiding direct contact between the heating tube 10 and the cutting knife, which may cause burn damage to the surface of the cutting knife. The uniform heat conduction of the heat conducting plate 6 can make the cutting knife heated more evenly, increase the temperature of the cutting knife, and realize thermal cutting of the profile. The side strip 5 is connected to the heating main board 9, and the side strip 5 can block one side of the heat conducting plate 6 to avoid leakage from the edge of the heat conducting plate 6.

[0029] Embodiment 2

[0030] like Figure 1-Figure 5 As shown, the heat insulation board 3 includes a heat insulation layer 1 301 , an auxiliary layer 302 and a heat insulation layer 2 303 , and one side of the heat insulation layer 1 301 is composited with the auxiliary layer 302 .

[0031] One side of the auxiliary layer 302 is compounded with the second heat insulation layer 303 , and the thickness of the second heat insulation layer 303 is the same as that of the first heat insulation layer 301 .

[0032] An extension block 4 is fixedly connected to one side of the side strip 5 , an anti-sliding block 13 is fixedly connected to one side of the extension block 4 , and a fastening bolt 14 is threadedly connected to the extension block 4 .

[0033] An auxiliary layer 302 is used to connect the insulation layer 1 301 and the insulation layer 2 303 to further improve the insulation effect of the insulation board 3 and prevent the temperature from being too high when one side of the heating board comes into contact with the fingers of the staff. The extension block 4 is installed on one side of the side strip 5 to increase the contact area between the heating board and the cutting knife. The fastening bolt 14 is rotated to separate the two extension blocks 4, which can assist in separating the two heating main boards 9 from both sides of the cutting knife to realize the disassembly of the cutting knife.

[0034] The usage and working principle of this device are as follows: first, place the two heating main boards 9 on both sides of the cutting knife respectively, and then engage the engaging strip 12 with the engaging groove on one side of the splicing strip 8 to achieve the connection between the two heating main boards 9. At this time, the anti-sliding block 13 is overlapped on the knife surface, and the limit bolt 1 is rotated on the two heating main boards 9 so that the end of the limit bolt 1 is against the knife surface, and then the fastening bolt 14 is rotated on one side of the extension block 4 so that the end of the fastening bolt 14 is connected to the other extension block 4, and the position of the two heating main boards 9 is locked, thereby achieving the overall connection of the heating plates, connecting the external power supply, and installing a plurality of heating wires inside the heating tube 19. After the power supply is connected, the heating tube 10 can achieve heating, and the heat conducting plate 6 can achieve heat conduction, so as to quickly heat the cutting knife. , the cutting knife can be moved by holding the knife handle to cut the profile. The heat conducting plate 6 is made of alumina ceramic material, the heat insulating layer 1 301 is a polystyrene board, the auxiliary layer 302 is made of a rock wool board, and the heat insulating layer 2 303 contains glass fiber. The three-layer composite structure can slow down the speed of heat conduction, thereby preventing the high temperature of the heating tube 10 from being quickly conducted to the heat insulating layer 1 301, so that the surface temperature of the heat insulating plate 3 is low, which is convenient for operators to contact and disassemble the heating plate. When the heating plate needs to be disassembled, the fastening bolt 14 can be rotated in the opposite direction to release the connection state of the two extension blocks 4, separate the clamping strip 12 from the clamping groove, and separate the two heating main boards 9. At this time, one side of the heat conducting plate 6 is separated from the knife surface, and the overall disassembly of the heating plate can be realized.
