[0013] Compared with the prior art, the control panel of the present invention introduces the thermal conductive silicone slurry into the main material bin through automatic control, and introduces the thermal conductive silicone outer film slurry into the outer film material bin at the same time, and the thermal conductive silicone outer film slurry and the thermal conductive silicone slurry are simultaneously sent into the interior of the concentric connecting tube under the action of the axial flow pump, and the thermal conductive silicone outer film slurry is flatly coated on the surface of the thermal conductive silicone slurry by the coating mechanism, and at the same time, reinforcing ribs made of the thermal conductive silicone outer film slurry are formed on the surface of the thermal conductive silicone slurry, thereby strengthening the structural strength of the thermal conductive silicone, and then heated and vulcanized by the vulcanization mechanism, and synchronously transported to the calendering mechanism for shaping, and the thermal conductive silicone after shaping is cut at a fixed distance by the cutting structure, and at the same time, the harmful gas generated by the vulcanization inside the outer box of the equipment is introduced into the interior of the recovery pipe by the fan, and the harmful gas is dissolved and absorbed by the solution inside the recovery tank body, and the purified gas is discharged from the top of the recovery tank body.

[0014] The thermal conductive silicone slurry is introduced into the main material bin, and the thermal conductive silicone outer film slurry is introduced into the outer film material bin at the same time. Under the action of the axial flow pump, the thermal conductive silicone outer film slurry and the thermal conductive silicone slurry are simultaneously sent into the interior of the concentric connecting tubes, the thermal conductive silicone slurry flows into the interior of the inner tube, and the thermal conductive silicone outer film slurry flows into the gap between the outer wall of the inner tube and the inner wall of the outer tube. After the thermal conductive silicone slurry flows out of the bottom end of the inner tube, the thermal conductive silicone outer film slurry can be wrapped around the outer wall of the thermal conductive silicone slurry.

[0015] When the thermal conductive silicone slurry is coated, the coating thickness is controlled by adjusting the tightness of the binding hoop. The tighter the binding hoop is, the thinner the film is, and the looser the binding hoop is, the thicker the film is. The binding hoop drives the shrinking tube to contract, so that the shrinking tube drives the bottom ends of several metal arc sheets to shrink. The size of the gap between the inner wall of the metal arc sheet and the outer wall of the inner tube is controlled by the extrusion of the metal arc sheet, thereby controlling the amount of thermal conductive silicone outer film slurry passing through the gap, thereby controlling the coating thickness. At the same time, a groove is provided on the inner surface of the metal arc sheet, so that the amount of thermal conductive silicone outer film slurry at the groove is greater than the amount at the gap, so that more thermal conductive silicone outer film slurry can be squeezed out at the groove, so that reinforcing ribs made of thermal conductive silicone outer film slurry as raw material can be formed on the outer wall of the thermal conductive silicone slurry at the groove, thereby enhancing the structural strength of the thermal conductive silicone.

[0016] During shaping, the control panel controls the rotation of the output end of the servo motor and the extension of the output end of the thickness control cylinder through control parameters. The rotation of the output end of the servo motor drives the roller 802 to rotate, so that the conveyor belt rotates, and the slurry clamped by the conveyor belt and the conveyor belt is pressed and shaped. The output end of the thickness control cylinder extends to control the shaping thickness. The thickness control cylinder extends to rotate the upper bracket around the fixed axis, so that the roller on the upper bracket is close to the conveyor belt, so that the conveyor belt is pressed to shape the slurry on the conveyor belt. At the same time, the airflow flows inward from the square groove, and the shaping of the slurry is accelerated by the airflow. The airflow introduces the toxic gas generated by sulfide into the solution inside the recovery tank to dissolve and absorb the harmful gas.

[0029] During the specific implementation, the control panel 10 introduces the thermal conductive silicone slurry into the main material bin 3 through automatic control, and introduces the thermal conductive silicone outer film slurry into the outer film material bin 2 at the same time, and the thermal conductive silicone outer film slurry and the thermal conductive silicone slurry are simultaneously sent into the interior of the concentric connecting tube 5 under the action of the axial flow pump 4, and the thermal conductive silicone outer film slurry is flatly coated on the surface of the thermal conductive silicone slurry through the coating mechanism 6, and at the same time, reinforcing ribs made of thermal conductive silicone outer film slurry are formed on the surface of the thermal conductive silicone slurry, thereby strengthening the structural strength of the thermal conductive silicone, and then heated and vulcanized by the vulcanization mechanism 7, and synchronously transported to the calendering mechanism 8 for shaping. After the shaping, the thermal conductive silicone is cut at a fixed distance by the cutting structure 9, and at the same time, the harmful gas generated by the vulcanization inside the equipment outer box 1 is introduced into the interior of the recovery pipe 101 by the fan 103, and the harmful gas is dissolved and absorbed by the solution inside the recovery tank 102, and the purified gas is discharged from the top of the recovery tank 102.

[0030] Harmful gases produced during the sulfidation process include but are not limited to sulfur dioxide, hydrogen sulfide and volatile organic compounds.

[0031] For further reference, Figure 6 The concentric connecting pipe 5 includes an outer tube 501 fixed on the equipment outer box 1, and a concentrically arranged inner tube 502 is provided on the top of the outer tube 501. The discharge pipe of the outer film material bin 2 is connected to the outer wall of the outer tube 501 and penetrates the inside of the outer tube 501. The discharge pipe of the main material bin 3 is connected to the top of the inner tube 502.

[0032] During the specific implementation, the thermal conductive silicone slurry is introduced into the main material bin 3, and the thermal conductive silicone outer film slurry is introduced into the outer film material bin 2 at the same time. Under the action of the axial flow pump 4, the thermal conductive silicone outer film slurry and the thermal conductive silicone slurry are simultaneously sent into the interior of the concentric connecting tube 5, and the thermal conductive silicone slurry flows into the interior of the inner tube 502. The thermal conductive silicone outer film slurry flows into the gap between the outer wall of the inner tube 502 and the inner wall of the outer tube 501. After the thermal conductive silicone slurry flows out of the bottom end of the inner tube 502, the thermal conductive silicone outer film slurry can be wrapped around the outer wall of the thermal conductive silicone slurry.

[0033] For further reference, Figure 7 and Figure 8The coating mechanism 6 includes an upper connecting ring 601 fixedly connected to the bottom end of the outer tube 501, and a plurality of evenly distributed metal arc sheets 602 are integrally connected to the bottom end of the upper connecting ring 601. The inner surface of the metal arc sheet 602 is provided with a groove, and a rubber flexible sheet 603 is provided between the gaps of the plurality of metal arc sheets 602. A gathering cylinder 604 is fixedly connected to the bottom ends of the metal arc sheets 602 and the rubber flexible sheets 603. The gathering cylinder 604 is made of a heat-insulating flexible material, and a plurality of limiting rings 605 are provided on the outer wall of the gathering cylinder 604. A tying hoop 606 is provided inside the limiting rings 605 at the same height, and a lower connecting ring 607 is provided at the bottom end of the gathering cylinder 604. The bottom end of the lower connecting ring 607 is connected to the vulcanization mechanism 7.

[0034] In specific implementation, when the thermal conductive silicone slurry is coated, the coating thickness is controlled by adjusting the tightness of the tie hoop 606. The tighter the tie hoop 606 is, the thinner the film is, and the looser the tie hoop 606 is, the thicker the film is. The tie hoop 606 pulls the retracting tube 604 to contract, so that the retracting tube 604 drives the bottom ends of the metal arc sheets 602 to retract. The size of the gap between the inner wall of the metal arc sheet 602 and the outer wall of the inner tube 502 is controlled by the extrusion of the metal arc sheet 602, thereby controlling the amount of thermal conductive silicone outer film slurry passing through the gap, thereby controlling the coating thickness. At the same time, a groove is provided on the inner surface of the metal arc sheet 602, so that the amount of thermal conductive silicone outer film slurry at the groove is greater than the amount at the gap, so that more thermal conductive silicone outer film slurry can be squeezed out at the groove, so that reinforcing ribs made of thermal conductive silicone outer film slurry as raw material can be formed on the outer wall of the thermal conductive silicone slurry at the groove, thereby enhancing the structural strength of the thermal conductive silicone.

[0035] Thermally insulating flexible materials include, but are not limited to, ceramic fibers.

[0036] Furthermore, the bottom end of the inner tube 502 is flush with the top end of the gathering tube 604; In a specific implementation, the thermally conductive silicone slurry squeezed out from the inner tube 502 can enter the interior of the gathering tube 604 and then be coated.

[0037] For further reference, Figure 5 and Figure 6 The vulcanizing mechanism 7 includes an arc tube 701 connected to the bottom end of the lower connecting ring 607, an electric heating tube 705 is provided on the outer wall of the arc tube 701, the end of the arc tube 701 is horizontally arranged, a trapezoidal tube 702 is integrally connected to the end of the arc tube 701, two parallel side plates 703 are provided at the end of the trapezoidal tube 702, and square grooves 704 are provided at the ends of the two side plates 703, and the calendering mechanism 8 is arranged between the two side plates 703; In a specific implementation, during the vulcanization, the slurry inside the arc tube 701 is heated and vulcanized by the electric heating tube 705 , and the heated and vulcanized slurry passes through the trapezoidal tube 702 and enters between the two side plates 703 .

[0038] For further reference, Figures 2 to 4 The calendering mechanism 8 includes a lower bracket 801 fixed to the inside of the equipment outer box 1, and both ends of the top of the lower bracket 801 are rotatably connected with roller shafts 802, and a plurality of roller shafts 803 rotatably connected to the lower bracket 801 are provided between the two roller shafts 802, and conveyor belts 804 are provided on the roller shafts 802 and 803, and a servo motor 806 fixed to the lower bracket 801 is provided on the shaft of the roller shaft 802 at the end, and a fixed shaft 807 is fixedly connected between the two side walls of the equipment outer box 1, and the calendering mechanism 8 also includes a fixed shaft 807 rotatably connected to the fixed shaft 807. 07, the fixed shaft 807 runs through the middle of the shaft of the roller shaft 3 809, the other end of the upper bracket 808 is rotatably connected with the roller shaft 1 802, and a plurality of roller shafts 4 810 are arranged between the roller shaft 1 802 and the roller shaft 3 809 on the upper bracket 808, and a pressing conveyor belt 811 is arranged on the roller shaft 1 802, the roller shaft 3 809 and the roller shaft 4 810, and the top of the control end of the upper bracket 808 is connected with a thickness control cylinder 812 through a hole-ball matching method, and the top of the thickness control cylinder 812 is fixedly connected to the top wall of the equipment outer box 1; In specific implementation, when shaping is performed, the control panel 10 controls the output end of the servo motor 806 to rotate and the output end of the thickness control cylinder 812 to extend through control parameters. The rotation of the output end of the servo motor 806 drives the roller 802 to rotate, so that the conveyor belt 804 rotates, and the slurry clamped by the conveyor belt 804 and the pressing conveyor belt 811 is pressed and shaped. The output end of the thickness control cylinder 812 extends to control the shaping thickness. The thickness control cylinder 812 extends to rotate the upper bracket 808 around the fixed axis 807, so that the roller 802 on the upper bracket 808 is close to the conveyor belt 804, so that the pressing conveyor belt 811 shapes the slurry on the conveyor belt 804. At the same time, the airflow flows inward from the square groove 704, and the shaping of the slurry is accelerated by the airflow. The airflow introduces the toxic gas generated by vulcanization into the solution inside the recovery tank 102 to dissolve and absorb the harmful gas.

[0039] Further, the radius of roller 1 802 is greater than the radius of roller 2 803, the radius of roller 1 802 and roller 3 809 are equal, the radius of roller 1 802 and roller 4 810 are both greater than the height of side plate 703, and the radius of roller 1 802 is greater than the radius of roller 4 810; In a specific implementation, the radii of roller one 802 and roller four 810 are both greater than the height of the side plate 703, so that the thickness control cylinder 812 can have a larger adjustment range when adjusting the molding thickness. After the thickness control cylinder 812 is fully extended and the conveyor belt 811 is pressed against the conveyor belt 804, the rotating shafts of roller one 802 and roller four 810 will not contact the side plate 703.

[0040] Furthermore, the conveyor belt 804 and the pressing conveyor belt 811 are seamlessly connected between the two side plates 703, and the conveyor belt 804 and the pressing conveyor belt 811 are both set to be taut, the surface of the conveyor belt 804 contacts the bottom of the trapezoidal cylinder 702, and the surface of the pressing conveyor belt 811 contacts the top of the trapezoidal cylinder 702.

[0041] In a specific implementation, the conveyor belt 804 and the pressure conveyor belt 811 include but are not limited to metal iron sheets; As the slurry is continuously extruded from the trapezoidal cylinder 702 , it is compacted and shaped by the conveyor belt 804 and the pressure conveyor belt 811 .

[0042] Seamless connection is a high-precision gap that tends to be seamless, that is, the gap is very small and can be ignored.

[0043] Seamless connection technology uses existing technology.

The output end of the vertical cylinder 903 extends downward, so that the cutting mold 904 moves downward to cut the thermal conductive silicone inside the square groove 704. At the same time, under the control command of the control panel 10, the horizontal cylinder 901 and the thermal conductive silicone move synchronously.

[0045] Furthermore, the control panel 10 is a touch screen controller; In the specific implementation, the control panel 10 is a touch screen controller, so that the control panel 10 can set parameters through touch selection. The parameters include but are not limited to: the output power of the fan 103, the output power of the axial flow pump 4, the heating power of the electric heating tube 705, the output power of the servo motor 806, the telescopic distance of the output end of the thickness control cylinder 812, the telescopic distance of the output end of the horizontal cylinder 901, and the telescopic distance of the vertical cylinder 903.
