[0014] Preferably, a sealing rubber rolling shaft is provided inside the winding wheel, and the sealing rubber rolling shaft is fixedly connected to the filter drive mechanism, and the filter drive mechanism is connected to the winding wheel through a sealing rubber rolling spring, and a sealing rubber roll is rolled up on the outside of the winding wheel, and one end of the sealing rubber roll is fixedly connected to the filter mechanism, and sealing rubber roll sliding grooves are symmetrically opened on the front and rear sides of the inner wall of the filter drive mechanism, and the sealing rubber roll sliding grooves are slidably connected to the sealing rubber roll.

[0015] A method for preparing a heat-resistant aging repair adhesive preparation device comprises the following steps:

[0016] Step 1: weigh the raw materials, epoxy resin 90 to 100 parts; toughening agent 8 to 10 parts; coupling agent 2.3 to 3.3 parts; curing agent 35 to 42 parts and silicon powder 130 to 160 parts;

[0017] Step 2: Add epoxy resin and toughening agent into the inner shell, start the drive motor, drive the stirring rod and stirring paddle to rotate, so as to mix, mix for 25 to 32 minutes, then add coupling agent, curing agent and silicon powder, turn on the heating element to heat the water in the outer shell, so as to heat the materials, raise the temperature to 50 to 60°C for uniform mixing;

[0018] Step 3: When discharging, start the driving screw, which drives the driving ear to move upward, thereby driving the filter mechanism to move upward. When the rubber solution containing foam passes through the filter mechanism, the particles or bubbles in the foam will be blocked by the mesh or fiber, thereby achieving a filtering effect. The fiber surface of the filter may have a certain adsorption capacity, which can adsorb certain components in the foam, and help to further remove impurities and pollutants in the foam. When the filter mechanism moves upward, the sealing rubber roll below is stretched, so that the stored sealing rubber roll drives the reel to rotate and unfold, and at the same time, the two ends of the sealing rubber roll slide with the sealing rubber roll slide groove, and the upper reel reels the upper sealing rubber roll due to the elastic force of the sealing rubber roll reel spring;

[0019] Step 4: When the rotating filter plate is higher than the glue pump, the rotating filter plate lifted by the glue pump rotates downward to maintain the same horizontal state with the filter plate. When the upper end of the filtering mechanism contacts the stirring paddle, the electric telescopic cylinder is retracted, and the electric telescopic cylinder drives the stirring paddle slot baffle to slide inside the stirring paddle slot baffle slide slot, thereby emptying the stirring paddle slot. When it moves above the stirring paddle, the stirring paddle is completely moved out of the stirring paddle slot, and the electric telescopic cylinder is extended again. The electric telescopic cylinder drives the stirring paddle slot baffle to slide inside the stirring paddle slot, thereby filling the stirring paddle slot. When the filtering mechanism moves above the glue liquid, the filtration of the glue liquid is completed, and then the ultrasonic generator is turned on. When the ultrasonic vibration generated by the ultrasonic generator acts on the foam, the remaining foam is defoamed. The ultrasonic wave will generate a large number of tiny bubbles, which will expand and collapse rapidly under the action of the ultrasonic vibration. The shear force and pressure changes generated by ultrasonic vibration on the liquid reduce the interfacial tension between the gas and the glue, which is conducive to the collapse of bubbles. At the same time, the stirring effect of ultrasonic vibration on the liquid can make the bubbles better contact with the surrounding liquid, thereby accelerating the collapse of bubbles. During the ultrasonic defoaming process, the high-frequency vibration of the ultrasonic wave has a strong mechanical effect on the foam liquid. This mechanical effect not only destroys the structure of the bubble, but also causes the bubble wall to vibrate strongly, eventually causing the bubble to burst. In addition, the pressure wave and shear force generated when the ultrasonic wave propagates in the liquid also help to eliminate bubbles.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. When the present invention discharges materials, the driving screw is started, and the driving screw drives the driving ear to move upward, thereby driving the filter mechanism to move upward. When the glue solution containing foam passes through the filter mechanism, the particles or bubbles in the foam will be blocked by the mesh or fiber, thereby achieving a filtering effect. The fiber surface of the filter may have a certain adsorption capacity, which can adsorb certain components in the foam, and help to further remove impurities and pollutants in the foam. When the filter mechanism moves upward, the sealing rubber roll below is stretched, so that the stored sealing rubber roll drives the winding wheel to rotate and unfold, and at the same time, the two ends of the sealing rubber roll slide with the sealing rubber roll slide groove, and the upper winding wheel winds up the upper sealing rubber roll due to the elastic force of the sealing rubber roll winding spring. When the rotating filter plate is higher than the glue pump, the rotating filter plate lifted by the glue pump rotates downward to maintain the same horizontal state with the filter plate. When the upper end of the filtering mechanism contacts the stirring paddle, the electric telescopic cylinder is retracted, and the electric telescopic cylinder drives the stirring paddle slot baffle to slide inside the stirring paddle slot baffle slide slot, thereby emptying the stirring paddle slot. When it moves above the stirring paddle, the stirring paddle is completely moved out of the stirring paddle slot, and the electric telescopic cylinder is extended again. The electric telescopic cylinder drives the stirring paddle slot baffle to slide inside the stirring paddle slot, thereby filling the stirring paddle slot. When the filtering mechanism moves above the glue liquid, the filtration of the glue liquid is completed, and then the ultrasonic generator is turned on. When the ultrasonic vibration generated by the ultrasonic generator acts on the foam, the remaining foam is defoamed. The ultrasonic wave will generate a large number of tiny bubbles, which will expand and collapse rapidly under the action of the ultrasonic vibration. The shear force and pressure changes generated by ultrasonic vibration on the liquid reduce the interfacial tension between the gas and the glue liquid, which is conducive to the collapse of bubbles. At the same time, the stirring effect of ultrasonic vibration on the liquid can make the bubbles better contact with the surrounding liquid, thereby accelerating the collapse of the bubbles. During the ultrasonic defoaming process, the high-frequency vibration of the ultrasonic wave has a strong mechanical effect on the foam liquid. This mechanical effect not only destroys the structure of the bubble, but also causes the bubble wall to vibrate strongly, eventually causing the bubble to burst. In addition, the pressure waves and shear forces generated when the ultrasonic wave propagates in the liquid also help to eliminate bubbles, solving the problem of bubbles appearing during the preparation of the repair glue preparation device. The presence of bubbles will weaken the contact area between the repair glue and the bonded material, thereby reducing the bonding strength. Bubbles will hinder the uniform curing of the repair glue, resulting in defects in the cured repair glue, which will reduce the durability and service life of the repair glue.

[0022] 2. When cleaning the equipment, adjust the three-way valve to connect the feed pipe and the flushing pipe, input the flushing water into the feed pipe, then start the rubber pump to reverse, pump the flushing water into the inner shell, then turn on the stirring paddle, make the flushing water fully contact with the inner wall of the inner shell and the stirring paddle, and turn on the ultrasonic generator at the same time. When the ultrasonic wave of the ultrasonic generator propagates in the flushing water, due to the nonlinear effect, acoustic cavitation will occur. When the sound intensity reaches a certain value, tiny cavitation bubbles are generated in the liquid and instantly close strongly. These bubbles will generate strong shock waves when they close. This shock wave can destroy the adsorption of dirt on the surface of the cleaning parts, so that the dirt layer is dispersed, emulsified, and peeled off. In addition, the cavitation bubbles will cause the liquid itself to generate circulation during the vibration process, that is, the so-called acoustic flow, which can cause a high velocity gradient and viscous stress on the surface of the vibrating bubbles, promote the destruction and shedding of dirt on the surface of the cleaning parts, and at the same time, due to the transmission of the ultrasonic wave, the glue liquid adhering to the inner wall of the rubber pump and the feed pipe will fall off, effectively preventing the glue liquid from solidifying inside and affecting subsequent use.

[0031] When discharging, the driving screw 20 is started, and the driving screw 20 drives the driving ear 27 to move upward, thereby driving the filter mechanism 16 to move upward. When the glue liquid containing foam passes through the filter mechanism 16, the particles or bubbles in the foam will be blocked by the mesh or fiber, thereby achieving a filtering effect. The fiber surface of the filter may have a certain adsorption capacity, which can adsorb certain components in the foam, which helps to further remove impurities and pollutants in the foam. When the filter mechanism 16 moves upward, the sealing rubber roll 22 below is stretched, so that the stored sealing rubber roll 22 drives the winding wheel 21 to rotate and unfold.

When the ultrasonic vibration generated by the ultrasonic generator 19 acts on the foam, the remaining foam is defoamed, and the ultrasonic wave will generate a large number of tiny bubbles, which will expand and collapse rapidly under the action of the ultrasonic vibration. The shear force and pressure changes generated by ultrasonic vibration on the liquid reduce the interfacial tension between the gas and the glue, which is conducive to the collapse of bubbles. At the same time, the stirring effect of ultrasonic vibration on the liquid can make the bubbles better contact with the surrounding liquid, thereby accelerating the collapse of bubbles.

This mechanical effect not only destroys the structure of the bubble, but also causes the bubble wall to vibrate strongly, eventually causing the bubble to burst. In addition, the pressure wave and shear force generated when the ultrasonic wave propagates in the liquid also help to eliminate bubbles.

[0036] A method for preparing a heat-resistant aging repair adhesive preparation device comprises the following steps:

[0037] Step 1: weigh the raw materials, epoxy resin 90 to 100 parts; toughening agent 8 to 10 parts; coupling agent 2.3 to 3.3 parts; curing agent 35 to 42 parts and silicon powder 130 to 160 parts;

[0038] Step 2: Add epoxy resin and toughening agent into the inner shell 1, start the drive motor 4, drive the stirring rod 5 and the stirring paddle 9 to rotate, so as to mix, mix for 25 to 32 minutes, then add coupling agent, curing agent and silicon powder, turn on the heating element 10 to heat the water in the outer shell 2, so as to heat the materials, raise the temperature to 50 to 60°C for uniform mixing;

[0039] Step 3: When discharging, start the driving screw 20, and the driving screw 20 drives the driving ear 27 to move upward, thereby driving the filter mechanism 16 to move upward. When the glue containing foam passes through the filter mechanism 16, the particles or bubbles in the foam will be blocked by the mesh or fiber, thereby achieving a filtering effect. The fiber surface of the filter may have a certain adsorption capacity, which can adsorb certain components in the foam, and help to further remove impurities and pollutants in the foam. When the filter mechanism 16 moves upward, the sealing rubber roll 22 below is stretched, so that the stored sealing rubber roll 22 drives the winding wheel 21 to rotate and unfold, and at the same time, the two ends of the sealing rubber roll 22 slide with the sealing rubber roll slide 25, and the upper winding wheel 21 reels the upper sealing rubber roll 22 due to the elastic force of the sealing rubber roll winding spring 24;

[0040] Step 4: When the rotating filter plate 28 is higher than the glue pump 11, the rotating filter plate 28 lifted by the glue pump 11 rotates downward, thereby maintaining the same horizontal state with the filter plate 26. When the upper end of the filtering mechanism 16 contacts the stirring paddle 9, the electric telescopic cylinder 36 is retracted, and the electric telescopic cylinder 36 drives the stirring paddle slot baffle 33 to slide into the inside of the stirring paddle slot baffle slide 34, thereby vacating the stirring paddle slot 30. When it moves to the top of the stirring paddle 9, the stirring paddle 9 is completely moved out of the stirring paddle slot 30, and then the electric telescopic cylinder 36 is extended again. The electric telescopic cylinder 36 drives the stirring paddle slot baffle 33 to slide into the inside of the stirring paddle slot 30, thereby filling the stirring paddle slot 30. When the filtering mechanism 16 moves to the top of the glue liquid, the filtration of the glue liquid is completed, and then the ultrasonic generator 19 is turned on. When the ultrasonic vibration generated by the ultrasonic generator 19 acts on the foam, the remaining foam is defoamed, and the ultrasonic wave will generate a large number of tiny bubbles, which will expand and collapse rapidly under the action of the ultrasonic vibration. The shear force and pressure changes generated by ultrasonic vibration on the liquid reduce the interfacial tension between the gas and the glue, which is conducive to the collapse of bubbles. At the same time, the stirring effect of ultrasonic vibration on the liquid can make the bubbles better contact with the surrounding liquid, thereby accelerating the collapse of bubbles. During the ultrasonic defoaming process, the high-frequency vibration of the ultrasonic wave has a strong mechanical effect on the foam liquid. This mechanical effect not only destroys the structure of the bubble, but also causes the bubble wall to vibrate strongly, eventually causing the bubble to burst. In addition, the pressure wave and shear force generated when the ultrasonic wave propagates in the liquid also help to eliminate bubbles.

[0041] Working principle: When cleaning the equipment, adjust the three-way valve 13 to connect the feed pipe 12 and the flushing pipe 15, input flushing water into the feed pipe 12, then start the rubber pump 11 to reverse, pump the flushing water into the inner shell 1, turn on the stirring paddle 9, make the flushing water fully contact with the inner wall of the inner shell 1 and the stirring paddle 9, and turn on the ultrasonic generator 19 at the same time. When the ultrasonic wave of the ultrasonic generator 19 propagates in the flushing water, acoustic cavitation will be generated due to nonlinear effects. When the sound intensity reaches a certain value, tiny cavitation bubbles are generated in the liquid and instantly and strongly closed. These bubbles will generate strong shock waves when they are closed. This shock wave can destroy the adsorption of dirt and the surface of the cleaning parts, so that the dirt layer is dispersed, emulsified, and peeled off. In addition, the cavitation bubbles will cause the liquid itself to produce a circulation during the vibration process, namely the so-called acoustic flow, which can cause a very high velocity gradient and viscous stress to exist on the surface of the vibrating bubbles, thereby destroying and removing dirt from the surface of the cleaning parts. At the same time, the transmission of ultrasonic waves causes the glue liquid adhering to the inner walls of the glue pump 11 and the feed pipe 12 to fall off, effectively preventing the glue liquid from solidifying inside and affecting subsequent use.
