[0002] Thermally conductive silicone sheet is a thin sheet of thermally conductive material with excellent thermal conductivity and high temperature resistance. It is widely used in electrical appliances, radiators and other fields. During the preparation process of thermally conductive silicone sheet, it is necessary to mix the silicone base material with thermal conductive fillers, cross-linking agents, etc., and then spread the mixed material on a plane, or form it through a mold to form a sheet structure of the required thickness. During the mixing process, the existing device generally relies on a mixer for continuous stirring. During this process, the material is always in a directional rotating mixing state. At the same time, there will be a large number of bubbles inside the material due to stirring, which will reduce the overall stirring effect.

[0003] Therefore, a thermally conductive silicone sheet preparation device is now developed to address the above problems. Utility Model Content

[0007] Further description, it also includes a positioning mechanism, which includes a positioning frame. The left part of the base is connected to the positioning frame by bolts. A guide frame is installed on the positioning frame. A positioning belt is connected to the front side of the positioning frame, and the positioning belt passes through the guide frame.

[0008] Further description, a vacuum pump is installed on the upper right side of the lifting seat, and an exhaust pipe is connected between the vacuum pump and the sealing cover plate.

[0009] It is further described that the transmission assembly includes a transmission wheel and a transmission belt.

[0010] It is further explained that the left side of the positioning frame is an arc-shaped structure, which fits the outer surface of the mobile tank truck.

[0011] By adopting the above technical solution, the beneficial effects of the utility model are:

[0012] 1. In the process of stirring and mixing materials, the utility model relies on the mixing blades to drive the spiral blades to rotate continuously, so that the materials can move upward continuously during the mixing process, thereby making the material mixing more uniform and sufficient, and relies on the vacuum pump to continuously extract the excess gas inside the material, making the material mixture thicker, reducing the internal bubble content after the material is mixed, and improving the mixing quality.

DETAILED DESCRIPTION

[0019] The present invention will now be described more fully below with reference to the accompanying drawings, in which the present invention is shown in its currently preferred embodiments. However, the present invention can be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness, and these embodiments fully convey the scope of the present invention to the skilled person.

[0020] Example 1

[0021] A thermally conductive silicone sheet preparation device, such as Figure 1 and Figure 2 As shown, it includes a base 1, a hydraulic cylinder 2 is installed on the upper right side of the base 1 by bolts, the telescopic end of the hydraulic cylinder 2 is set to face upward, a lifting seat 3 is connected to the telescopic end of the hydraulic cylinder 2, the lifting seat 3 is slidably connected to the base 1, a sealing cover plate 4 is connected to the left side of the lifting seat 3, a vacuum pump 5 is installed on the upper right side of the lifting seat 3, an exhaust pipe is connected between the vacuum pump 5 and the sealing cover plate 4, a servo motor 6 is installed on the upper middle side of the lifting seat 3, the output shaft of the servo motor 6 is set to face upward, a mixing blade 8 is rotatably arranged on the sealing cover plate 4, a transmission assembly 7 is connected between the mixing blade 8 and the output shaft of the servo motor 6, the transmission assembly 7 includes a transmission wheel and a transmission belt, a mobile tanker 9 is placed on the base 1, the sealing cover plate 4 is clamped with the mobile tanker 9, and a lifting mechanism 10 for driving the spiral upward movement of the material is arranged between the sealing cover plate 4 and the mixing blade 8.

[0022] like Figure 1 and Figure 3 As shown, the recovery mechanism 10 includes a first transmission gear 101, the first transmission gear 101 is connected to the upper part of the mixing blade 8, a second transmission gear 102 is rotatably arranged on the upper part of the sealing cover plate 4, the first transmission gear 101 and the second transmission gear 102 are meshed with each other, an inner gear ring 103 is rotatably arranged on the upper part of the sealing cover plate 4, the inner gear ring 103 and the second transmission gear 102 are meshed with each other, and a spiral blade 104 is connected to the lower part of the inner gear ring 103.

[0023] It should be noted that when performing the preparation of thermal conductive silica gel, the present device can be used to assist in the preparation. First, the materials are poured into the mobile tanker 9 according to a certain proportion, and then the mobile tanker 9 is pushed to the upper left side of the base 1. Then, the telescopic end of the hydraulic cylinder 2 is controlled to move so that the lifting seat 3 starts to slide downward as a whole, so that the sealing cover plate 4 can be engaged with the mobile tanker 9 to complete the sealing of the mobile tanker 9. Then, the servo motor 6 is started, and the rotation of the output shaft of the servo motor 6 drives the transmission assembly 7 to operate, so that the mixing blade 8 starts to rotate at a high speed to move the materials in the mobile tanker 9. The materials are fully stirred. When the mixing blade 8 rotates at a high speed, the first transmission gear 101 drives the second transmission gear 102 to rotate, thereby rotating the inner gear ring 103. The rotation of the inner gear ring 103 drives the spiral blade 104 to rotate, thereby causing the materials in the mobile tank truck 9 to continuously surge upward, thereby improving the degree of sufficient material mixing. In this process, the vacuum pump 5 is started, and the vacuum pump 5 continuously extracts the air in the mobile tank truck 9, thereby causing the bubbles in the material to be continuously precipitated, making the material mixture thicker, reducing the internal bubble content after the material is mixed, and improving the mixing quality.

[0025] On the basis of Example 1, Figure 1 and Figure 4 As shown, it also includes a positioning mechanism 11, which includes a positioning frame 111. The left part of the base 1 is connected to the positioning frame 111 by bolts. The left side of the positioning frame 111 is an arc-shaped structure, which fits the outer surface of the mobile tanker 9. A guide frame 112 is installed on the positioning frame 111. The front side of the positioning frame 111 is connected to a positioning belt 113, and the positioning belt 113 passes through the guide frame 112.

[0026] It should be noted that when placing the mobile tank truck 9, in order to ensure that the sealing cover plate 4 can be snap-fitted with the mobile tank truck 9, the mobile tank truck 9 is positioned by means of the positioning frame 111. After positioning is completed, the mobile tank truck 9 is fixed by means of the cooperation of the positioning belt 113 and the guide frame 112, so as to maintain stability during the mixing and stirring process and avoid displacement of the mobile tank truck 9 due to stirring and shaking.
