[0037] The present invention provides a high-strength sealing adhesive preparation device, comprising a base 101 and a stirring tank 102; further comprising a preparation component 103; the preparation component 103 comprises a lifting mechanism 104 and a stirring mechanism 105; the lifting mechanism 104 comprises a stand 106, two guide rods 107, a slider 108, a screw 109, a servo motor 110 and a support beam 111; the stirring mechanism 105 comprises a stirring shaft 112, a stirring member 113 and a driving member 114; the stirring member 113 comprises a central tube 115, two stirring tubes 116, an electric heating rod 117 and two transverse tubes 118; the driving member 114 comprises a stand plate 119, a stirring motor 120, a driving gear 121 and a driven gear 122; the high-strength sealing adhesive The adhesive preparation device also includes a liquid storage box 123, a feeding tube 124, two limit blocks 125, a baffle 126, a mounting plate 127, a push rod 128, a contact block 129, a spring 130 and a cam 131; the bottom of the liquid storage box 123 has a first liquid outlet 132; the baffle 126 has a second liquid outlet 133; the contact block 129 includes a mounting block 134 and a roller 135; the high-strength sealing adhesive preparation device also includes two stabilizing components 136; the stabilizing component 136 includes a support plate 137, two sliding rods 138, a clamping block 139, a screw 140 and a knob 141; the above-mentioned solution solves the problem that the existing sealing adhesive is easily drawn into air to form bubbles during stirring preparation, resulting in unevenness and discontinuity.

[0038] According to this specific embodiment, the stirring tank 102 is located on the top of the base 101 ; the stirring tank 102 is of prior art and can be electrically heated to control the temperature, and the base 101 is used to place the stirring tank 102 .

[0039] Furthermore, the stirring mechanism 105 is arranged above the stirring tank 102 for rotating stirring, and the stirring mechanism 105 is driven to move up and down by the lifting mechanism 104. The stirring mechanism 105 can rotate for stirring, and the lifting mechanism 104 is used to drive the stirring mechanism 105 to move up and down, and the stirring mechanism 105 can be extended into the stirring tank 102, or can be removed from the stirring tank 102, and the lifting mechanism 104 can also drive the stirring mechanism 105 to move back and forth. When in use, the stirring tank 102 is placed on the base 101 and is located directly below the stirring mechanism 105, and then the raw materials are added into the stirring tank 102, and the stirring tank 102 is powered on for heating, and then the lifting mechanism 104 and the stirring mechanism are started. The stirring mechanism 105 extends into the stirring tank 102 to rotate and stir the raw materials. At the same time, the lifting mechanism 104 also drives the stirring mechanism 105 to rise and fall back and forth. When rising and falling back and forth, the stirring mechanism 105 does not leave the liquid surface of the liquid raw material mixture at the highest. In this way, the stirring mechanism 105 rotates while rising and falling back and forth, which can change the flow pattern of the liquid raw material mixture and make it more complex. At the same time, the continuity of the vortex can be interrupted, which helps to prevent the formation of a stable vortex structure and will not involve air, thereby solving the problem that the existing sealing adhesive is easily involved in air to form bubbles during stirring and preparation, resulting in unevenness and discontinuity. At the same time, the stirring mechanism 105 moves up and down, which can also improve the vertical mixing of the liquid raw material mixture, avoid dead corners of stirring, and make the stirring more uniform.

[0040] Furthermore, the stand 106 is fixedly arranged on the top of the base 101; the two guide rods 107 are respectively fixedly arranged on the inner side of the stand 106; the slider 108 is slidably connected to the stand 106, and is respectively slidably connected to the two guide rods 107, and is located on the inner side of the stand 106; the screw rod 109 is rotatably connected to the stand 106, and is threadedly connected to the slider 108, and passes through the slider 108; the servo motor 110 is fixedly arranged on the top of the stand 106; the output end of the servo motor 110 is fixedly connected to the screw rod 109; the support beam 111 is fixedly arranged on one side of the slider 108. The stand 106 is provided with a sliding groove for slidingly installing the slider 108, and the two guide rods 107 are used to enhance the sliding stability of the slider 108. The servo motor 110 is used to drive the screw rod 109 to rotate, and the rotation of the screw rod 109 can drive the slider 108 to slide and rise and fall, thereby driving the support beam 111 to rise and fall, and finally driving the stirring mechanism 105 to rise and fall.

[0041] Further, the stirring shaft 112 is rotatably arranged on one side of the support beam 111 and passes through the support beam 111; the stirring member 113 is fixedly arranged at the bottom of the stirring shaft 112; the driving member 114 is arranged on the support beam 111 and is used to drive the stirring shaft 112 to rotate. The stirring shaft 112 is rotatably arranged on the support beam 111, and the driving member 114 drives the stirring shaft 112 to rotate, and the stirring shaft 112 drives the stirring member 113 to rotate to perform a stirring action.

[0042] Furthermore, the central tube 115 is fixedly arranged at the bottom of the stirring shaft 112; the two stirring tubes 116 are respectively fixedly arranged on one side of the central tube 115 and are respectively connected to the central tube 115; the electric heating rod 117 is fixedly arranged inside the central tube 115; the two transverse tubes 118 are respectively connected to the two stirring tubes 116 and are respectively connected to the central tube 115, and are respectively located on the sides of the central tube 115. The center tube 115 is hollow inside, and is flange-connected to the bottom of the stirring shaft 112. The electric heating rod 117 is installed inside. The connecting line of the electric heating rod 117 is routed through the hollow stirring shaft 112. The two curved stirring tubes 116 are connected and arranged on the side of the center tube 115, and are reinforced by the two transverse tubes 118. The two transverse tubes 118 are also hollow inside. In this way, the center tube 115, the two stirring tubes 116 and the two transverse tubes 118 form a connected cavity filled with water. After the electric heating rod 117 is energized, the water temperature rises. In this way, the stirring member 113 can also heat the liquid raw material mixture during stirring. Since the solid dissolves during stirring of the raw materials, the solid dissolves during stirring of the raw materials. After entering the liquid, the liquid raw material mixture is relatively viscous. The stirring tank 102 can be electrically heated to improve its fluidity. However, the temperature of the liquid raw material mixture at the edge rises faster than that of the liquid raw material mixture in the inner circle, causing the liquid raw material mixture in the stirring tank 102 to have uneven temperature, resulting in fluidity differences. The high temperature parts have better fluidity, while the low temperature parts have poor fluidity, and cannot be stirred evenly. The stirring element 113 of the present application is used to heat the liquid raw material mixture while stirring, and the stirring tank 102 is used to evenly heat the liquid raw material mixture, so that the fluidity of the entire liquid raw material mixture is consistent, and it can be stirred more evenly, and the sealing adhesive finally prepared will also be more uniform.

[0043] Furthermore, the vertical plate 119 is fixedly arranged on the top of the support beam 111; the stirring motor 120 is fixedly arranged on one side of the vertical plate 119; the driving gear 121 is fixedly arranged on the output end of the stirring motor 120; the driven gear 122 is fixedly arranged on the stirring shaft 112 and meshes with the driving gear 121. The vertical plate 119 is used to install the stirring motor 120, the stirring motor 120 drives the driving gear 121, the driving gear 121 drives the driven gear 122, and the driven gear 122 drives the stirring shaft 112 to rotate. The stirring shaft 112 is a hollow shaft. This driving method is used in order not to block the top of the stirring shaft 112, and to facilitate the routing of the connecting wire of the electric heating rod 117. The connecting wire can be connected to an external power supply using a conductive slip ring, which does not affect the rotation and can also energize the electric heating rod 117.

[0044] Furthermore, the liquid storage box 123 is fixedly arranged at the bottom of the support beam 111; the bottom of the liquid storage box 123 has a first liquid outlet 132; the feeding pipe 124 is fixedly arranged on one side of the liquid storage box 123 and is connected to the liquid storage box 123; the two limit blocks 125 are respectively fixedly arranged at the bottom of the liquid storage box 123; the baffle 126 is slidably connected to the liquid storage box 123, and is slidably connected to the two limit blocks 125, and is located at the bottom of the liquid storage box 123; the baffle 126 has a first liquid outlet 132; the feeding pipe 124 is fixedly arranged on one side of the liquid storage box 123 and is connected to the two limit blocks 125, and is located at the bottom of the liquid storage box 123; the baffle 126 has a first liquid outlet 132; the feeding pipe 124 is fixedly arranged on one side of the liquid storage box 123 and is connected to the two limit blocks 125, and is located at the bottom of the liquid storage box 123; the feeding pipe 124 is fixedly arranged on the ...

Defoaming agent can be added to the liquid storage box 123 through the feeding pipe 124. The two limit blocks 125 are used to make the sliding installation of the baffle 126 more stable. The baffle 126 is L-shaped. The mounting plate 127 is used to slidably install the push rod 128. When in use, the stirring shaft 112 rotates, and the stirring shaft 112 drives the cam 131 to rotate. When the cam 131 rotates to a suitable position, it can push the contact block 129. The contact block 129 pushes the baffle 126 to slide through the push rod 128. At this time, the first liquid outlet 132 is connected with the second liquid outlet 133, and the defoaming agent falls smoothly and is added to the stirring tank 102.
