[0019] Compared with the prior art, the present invention has the following beneficial effects: the present invention has a scientific and reasonable structure and is safe and convenient to use:

[0020] 1. A stirring and defoaming component is provided, which can stir the epoxy resin during the processing, which is conducive to bursting some bubbles inside the epoxy resin, and can also stir some bubbles inside the epoxy resin to the surface of the epoxy resin, thereby facilitating defoaming;

[0021] By providing a driving motor, a first rotating rod, a disc, a connecting rod, a gear ring, a gear, a second rotating rod and a connecting seat, during the defoaming process, the driving motor is controlled to operate, and the driving motor is used to drive the first rotating rod to rotate, and the first rotating rod rotates to rotate the connecting seat, and the connecting seat rotates to drive the second rotating rod to rotate, and the second rotating rod rotates to rotate the gear on the surface of the gear ring, and then the second rotating rod rotates, so that the epoxy resin can be stirred, which can not only make some bubbles inside the epoxy resin burst, but also can stir some bubbles inside the epoxy resin to the surface of the epoxy resin, which is convenient for the bubble bursting;

[0022] And by using the rectangular stirring frame, the spikes and the spiral auger, on the one hand, the bubbles inside the epoxy resin can be punctured by the spikes during the stirring process, and on the other hand, the spiral auger can not only stir the epoxy resin, but also transport the epoxy resin on the lower side to the upper side, so that the bubbles inside the epoxy resin can be punctured by the spikes;

[0023] And through the use of the elastic telescopic rod, the disc, the fixed disc, the first sliding rod and the inclined cylinder, during the stirring process, the rotation of the first rotating rod can drive the fixed disc to rotate, and the rotation of the fixed disc can then drive the first sliding rod to move on the surface of the inclined cylinder. Since there is a height difference on the surface of the inclined cylinder, the first sliding rod can cooperate with the elastic telescopic rod to drive the disc to move up and down in the defoaming barrel during the movement process, and then the rectangular frame and the spikes can move up and down inside the epoxy resin while rotating, thereby improving the defoaming efficiency of the spikes.

[0024] 2. A heating component is provided, which can cause friction between the first friction plate and the second friction plate during stirring, so that the first friction plate and the second friction plate generate heat by friction. The generated heat is transported to the inside of the epoxy resin through the heat-conducting fins, and combined with stirring, the heat can be evenly distributed inside the epoxy resin, and then the bubbles can be heated, causing the bubbles to expand and burst.

[0025] 3. A vacuum defoaming component is provided, which can extract the air in the defoaming barrel on the one hand, so that the bubbles burst under the action of pressure, and on the other hand, it can control the reciprocating movement of the defoaming barrel according to the number of bubbles, thereby accelerating the defoaming efficiency;

[0026] Through the coordinated use of the exhaust pipe, activated carbon box, vacuum pump and exhaust pipe, when defoaming is required, the vacuum pump is started. The operation of the vacuum pump can discharge the gas in the defoaming barrel through the exhaust pipe, so that the defoaming barrel is in a vacuum state, which accelerates the bursting of bubbles. The activated carbon particles in the activated carbon box can adsorb the sucked gas to avoid direct discharge of the gas and prevent environmental pollution.

[0027] In conjunction with the use of the cylindrical barrel, the piston, the first moving rod, the first spring, the side tube, the elastic rubber sleeve, the exhaust hole, the resistance block and the pressure sensor, when the vacuum pump is in operation, when there are fewer bubbles in the defoaming barrel, the gas enters the cylindrical barrel through the vacuum pump, causing the air pressure inside the cylindrical barrel to increase; when the cylindrical barrel is filled with gas, the air pressure inside the cylindrical barrel overcomes the elastic force of the first spring, causing the first spring to compress, and at this time the piston drives the first moving rod to move downward, and the first moving rod moves downward to cause the resistance block to contact the pressure sensor, and at this time the pressure sensor can be used to control the reciprocating movement of the defoaming barrel. Accelerate the bursting of bubbles. As the gas is continuously discharged, the pressure of the cylinder continues to expand. When the pressure reaches a certain range, the pressure in the cylinder overcomes the elastic rubber sleeve, causing the elastic rubber sleeve to expand outward, thereby exposing the exhaust hole. As the bubbles gradually decrease, the amount of gas entering the cylinder decreases. When the air pressure in the cylinder is less than the elastic force of the first spring, the first spring stretches under the action of the elastic force, thereby driving the resistance block away from the pressure sensor. At this time, the defoaming barrel can be controlled to stop moving, and there is no need to keep the defoaming barrel moving continuously, which can save the use cost to a certain extent.

[0028] In addition, in conjunction with the U-shaped frame, the third rotating rod, the rotating motor, the rotating disk, the fourth rotating rod, the second moving rod, the limiting column and the fixed collar, when the pressure sensor senses pressure, the rotating motor can be controlled by the controller to run, and the rotating motor can be used to drive the third rotating rod to rotate, and the third rotating rod can be used to drive the two rotating disks to rotate, and then the fourth rotating rod, the second moving rod and the limiting column can be used to drive the defoaming barrel to move back and forth, so as to shake the epoxy resin and improve the defoaming efficiency.

[0053] It should be noted that the elastic force of the elastic rubber sleeve 78 is greater than the elastic force of the first spring 711 .

[0054] Working principle: When using this type of bubble elimination device to eliminate bubbles generated during the epoxy resin processing, first add the epoxy resin into the defoaming barrel 2 through the feed pipe 3;

[0055] After the epoxy resin is poured in, the vacuum pump 73 and the drive motor 51 can be started synchronously. When the vacuum pump 73 is running, the gas in the defoaming barrel 2 can be discharged through the exhaust pipe 71, so that the defoaming barrel 2 is in a vacuum state. At the same time, the drive motor 51 drives the first rotating rod 52 to rotate. The rotation of the first rotating rod 52 then rotates the connecting seat 515. The rotation of the connecting seat 515 then drives the second rotating rod 511 to rotate. The rotation of the second rotating rod 511 can then make the gear 510 rotate on the surface of the gear ring 59, and then the second rotating rod 511 can rotate, so that the epoxy resin can be fully stirred, which can not only make some bubbles inside the epoxy resin burst, but also can stir some bubbles inside the epoxy resin to the surface of the epoxy resin, causing the bubbles to burst under the action of vacuum.

[0056] During this process, the rotation of the first rotating rod 52 can drive the fixed disk 53 to rotate, and the rotation of the fixed disk 53 can then drive the first sliding rod 54 to move on the surface of the inclined cylinder 57. Since there is a height difference on the surface of the inclined cylinder 57, the first sliding rod 54 can cooperate with the elastic telescopic rod 55 to drive the disk 56 to move up and down in the defoaming barrel 2 during the movement process, and then the rectangular stirring frame 512 and the spikes 513 can move up and down inside the epoxy resin while rotating, thereby improving the defoaming efficiency of the spikes 513;

[0057] During this process, the first rotating rod 52 rotates while driving the first friction plate 63 to rotate. The rotation of the first friction plate 63 can cause friction with the second friction plate 64, so that the first friction plate 63 and the second friction plate 64 generate heat by friction. The generated heat is transported to the inside of the epoxy resin through the heat-conducting fins 62, and combined with stirring, the heat can be evenly distributed inside the epoxy resin, and then the bubbles can be heated, causing the bubbles to expand and burst.

[0058] When the vacuum pump 73 is in operation, when there are fewer bubbles in the defoaming barrel 2, gas enters the cylindrical barrel 75 through the vacuum pump 73, causing the air pressure inside the cylindrical barrel 75 to increase. When the gas pressure in the cylindrical barrel 75 is equivalent to the elastic force of the first spring 711, the first spring 711 is in an initial state. As the air pressure inside the cylindrical barrel 75 increases, the air pressure inside the cylindrical barrel 75 overcomes the elastic force of the first spring 711, causing the first spring 711 to compress, and the piston 79 drives the first moving rod 710 to move downward. The first moving rod 710 moves downward, thereby causing the resistance block 712 to contact the pressure The sensor 713 contacts, at this time the pressure sensor 713 sends a pressure signal to the controller (not shown in the figure), the controller then controls the rotation motor 715 to operate, the rotation motor 715 drives the third rotating rod 716 to rotate, the third rotating rod 716 rotates and then drives the two rotating disks 717 to rotate, the two rotating disks 717 rotate and then drive the fourth rotating rod 718 to rotate, the fourth rotating rod 718 rotates and then can drive the defoaming barrel 2 to move back and forth through the cooperation of the second moving rod 719 and the limiting column 720, which can shake the epoxy resin, improve the defoaming efficiency, and accelerate the bursting of bubbles;

[0059] As the bubbles burst, the gas continuously enters the cylindrical tube 75, and the pressure of the cylindrical tube 75 continuously increases. When the pressure reaches a certain range, the pressure in the cylindrical tube 75 overcomes the elastic force of the elastic rubber sleeve 78, causing the elastic rubber sleeve 78 to expand outward, thereby exposing the exhaust hole 77, and the gas can be adsorbed by the activated carbon particles in the activated carbon box 72 and discharged into the environment through the exhaust hole 77;

[0060] As the defoaming process continues, the bubbles gradually decrease. In this process, the amount of gas entering the cylindrical barrel 75 will decrease. When the air pressure in the cylindrical barrel 75 is less than the elastic rubber sleeve 78, the elastic rubber sleeve 78 will block the exhaust hole 77 under the action of its own elastic force. At this time, the gas no longer passes through the side tube 76. In this process, when the air pressure in the cylindrical barrel 75 is less than the elastic force of the first spring 711, the first spring 711 stretches under the action of the elastic force, and then can drive the resistance block 712 away from the pressure sensor 713. At this time, the defoaming barrel 2 can be controlled to stop moving. There is no need to keep the defoaming barrel 2 moving continuously, which can save the use cost to a certain extent. Finally, the epoxy resin in the defoaming barrel 2 can be taken out.

[0061] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents.
