[0002] Epoxy resin refers to an organic polymer compound containing two or more epoxy groups in its molecule. It can be used as anti-corrosion paint, metal primer and insulating paint, etc. It can also be used as an adhesive in the automotive, electronic and electrical fields.

[0003] Because epoxy resin is a two-component material, usually composed of epoxy resin and curing agent, these two components need to be fully integrated before use to enable the epoxy resin to exert its optimal performance. Otherwise, it will easily affect its curing effect, hardness, strength and other performance indicators.

However, this is not only time-consuming but also prone to produce bubbles, which affects the compactness of the epoxy resin. Therefore, a stirring device for epoxy resin manufacturing is proposed to address the above problems. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1 , Figure 2 , Figure 3 As shown, a stirring device for manufacturing epoxy resin comprises a stirring tank 1; a servo motor 11 is connected to the bottom of the stirring tank 1; a heating roller 12 is rotatably connected to the end of the servo motor 11; a plurality of stirring blades 13 are fixedly connected to the middle of the heating roller 12; a plurality of heat conducting plates 14 are fixedly connected to the middle of the heating roller 12; a heat conducting column 15 is fixedly connected to the middle of each of the heat conducting plates 14; a heat dissipation wire 16 is fixedly connected to the middle of the heat conducting column 15; when the epoxy resin in the stirring tank 1 needs to be stirred during operation, the servo motor 11 can be operated first to drive the heating roller 12 to rotate, and the heating roller 12 can drive the stirring blade 13 to rotate when rotating, so that the epoxy resin in the stirring tank 1 can be stirred. Stirring is performed, and the heating roller 12 generates heat while rotating. At this time, the heat conducting plate 14 can dissipate the heat generated by the heating roller 12, and then the heat conducting column 15 and the heat dissipating wire 16 will assist the heat conducting plate 14 to dissipate the heat better. This step can achieve the effect of stirring and heating the epoxy resin through the heating roller 12. The epoxy resin is heated to promote the reaction between the epoxy resin and the curing agent, so as to achieve the purpose of accelerating the reaction rate, improving the curing effect, saving stirring time and improving production efficiency. At the same time, heating can also reduce the easy appearance of bubbles in the epoxy resin during the stirring process, thereby causing defects on the surface of the epoxy resin produced.

[0024] like Figure 2 , Figure 4As shown, an exhaust fan 2 is fixedly connected to the top of the mixing tank 1; a cross support frame 21 is fixedly connected to the middle of the exhaust fan 2; a rotating shaft 22 is rotatably connected to the middle of the cross support frame 21; a plurality of fan blades 23 are fixedly connected to the middle of the rotating shaft 22; when working, the cross support frame 21 plays a role of supporting the rotating shaft 22. When the exhaust fan 2 is needed to work, the rotating shaft 22 can be rotated first. When the rotating shaft 22 rotates, it will drive the fan blades 23 to rotate. The rotation of the fan blades 23 will form a certain suction force, so that the inside of the mixing tank 1 can be exhausted and ventilated. In this step, the opening of the exhaust fan 2 can prevent the heating roller 12 from causing a large temperature difference between the inside and outside of the mixing tank 1 when heating, thereby causing water vapor to be generated inside the mixing tank 1. If the water vapor is not discharged in time at this time, it may cause the water vapor to be integrated into the epoxy resin, thereby causing the epoxy resin to have a cloudy appearance, amine blush, surface defects, incomplete or slow curing. At this time, the exhaust fan 2 can reduce the occurrence of such situations.

[0025] like Figure 2 , Figure 3 As shown, the middle of the heating roller 12 is fixed with multiple groups of support plates 3; the ends of the support plates 3 are fixedly connected with arc-shaped wall scrapers 31; the sides of the arc-shaped wall scrapers 31 are fixedly connected with connecting ropes 32; the ends of the connecting ropes 32 are fixedly connected with percussion hammers 33; during operation, when the heating roller 12 rotates, the support plates 3 will rotate with the rotation of the heating roller 12, and at the same time, the rotation of the support plates 3 will drive the arc-shaped wall scrapers 31 to rotate along the inner wall of the mixing tank 1, and when the arc-shaped wall scrapers 31 rotate, the connecting ropes 32 will be affected by it and drive the percussion hammers 33 to swing, so that the inner wall of the mixing tank 1 can be percussed. Tapping: In this step, the inner wall of the mixing tank 1 can be cleaned by the cooperation of the support plate 3 and the arc-shaped wall scraper 31, so as to prevent the epoxy resin from adhering to the inner wall of the mixing tank 1 when the epoxy resin is stirred, thereby easily causing insufficient stirring of the epoxy resin on the inner wall of the mixing tank 1, thereby affecting the standard of the final product. By using the hammer 33 to tap the inner wall of the mixing tank 1, the vibration caused by the tapping can be used to reduce the bubbles that may be generated by the epoxy resin during the stirring process, thereby improving the density of the epoxy resin and reducing surface defects.

[0026] like Figure 1 , Figure 2As shown, a fastening ring 4 is fixedly connected to the middle of the servo motor 11; a plurality of groups of spring columns 41 are fixedly connected to the middle of the fastening ring 4; shock-absorbing pads 42 are fixedly connected to the ends of the spring columns 41; during operation, when the servo motor 11 is working, it will generate certain vibrations, and at this time, the vibrations will be transmitted to the spring columns 41 through the fastening ring 4. The spring columns 41 will expand and contract under the influence of the vibrations, thereby alleviating part of the vibrations and transmitting the remaining vibrations to the shock-absorbing pads 42, and the shock-absorbing pads 42 will alleviate the vibration force received again. This step can assist in fixing the servo motor 11 through the effects of the fastening ring 4 and the spring columns 41, and at the same time, the spring columns 41 and the shock-absorbing pads 42 can achieve the effect of shock absorption and noise reduction, so as to reduce the transmission of noise and reduce noise pollution.

[0027] like Figure 1 As shown, a sound-absorbing louver 5 is fixedly connected to the top of the mixing tank 1; a plurality of groups of window leaves 51 are fixedly connected to the middle of the sound-absorbing louver 5; when working, the gas exhausted by the exhaust fan 2 will flow out to the outside through the sound-absorbing louver 5, and when the gas flows through the sound-absorbing louver 5, it will rub and interfere with the window leaves 51, thereby reducing the intensity of the noise. This step can reduce the noise generated by the exhaust fan 2 when it is working through the action of the sound-absorbing louver 5 and the window leaves 51, thereby reducing noise pollution and providing a better working environment for the staff.

[0028] like Figure 4 As shown, the end of the exhaust fan 2 is fixedly connected with a valve plate 6; when working, when the exhaust fan 2 discharges the gas, the valve plate 6 will be affected by the airflow and expand, so that the gas inside the mixing tank 1 can be smoothly discharged to the outside, and when the exhaust fan 2 is not working, the valve plate 6 will be in a closed state. This step is that when the epoxy resin inside the mixing tank 1 is stirred, it may be affected by the force and splash into the exhaust fan 2, thereby causing pollution to the exhaust fan 2 and affecting the normal operation of the exhaust fan 2. At this time, the opening of the valve plate 6 can reduce the occurrence of such situations.

[0029] like Figure 1 As shown, a transparent observation plate 7 is provided in the middle of the mixing tank 1; during operation, the stirring condition of the epoxy resin inside the mixing tank 1 can be observed through the transparent observation plate 7. This step is that the staff can use the transparent observation plate 7 to determine when to stop stirring the epoxy resin.

[0030] Working principle: during operation, when the epoxy resin in the stirring tank 1 needs to be stirred, the servo motor 11 can be operated first to drive the heating roller 12 to rotate. When the heating roller 12 rotates, it will drive the stirring blade 13 to rotate, so that the epoxy resin in the stirring tank 1 can be stirred. At the same time, the heating roller 12 will generate heat when it rotates. At this time, the heat conducting plate 14 can dissipate the heat generated by the heating roller 12, and then the heat conducting column 15 and the heat dissipating wire 16 will assist the heat conducting plate 14 to dissipate the heat better. This step can achieve the effect of stirring and heating the epoxy resin through the action of the heating roller 12, and the reaction between the epoxy resin and the curing agent is promoted by heating the epoxy resin. The purpose of accelerating the reaction rate, improving the curing effect, saving stirring time and improving production efficiency is achieved. At the same time, heating can also reduce the bubbles that are easy to appear in the epoxy resin during the stirring process, thereby causing defects on the surface of the epoxy resin produced. When working, the cross support frame 21 supports the rotating shaft 22. When the exhaust fan 2 is needed to work, the rotating shaft 22 can be rotated first. When the rotating shaft 22 rotates, the fan blades 23 will be driven to rotate. The rotation of the fan blades 23 will form a certain suction force, so that the inside of the stirring tank 1 can be exhausted and ventilated. This step can prevent the heating roller 12 from causing a large temperature difference between the inside and outside of the stirring tank 1 when heating, thereby causing the stirring As a result, water vapor is generated inside the tank 1. If the water vapor is not discharged in time, it may cause the water vapor to be integrated into the epoxy resin, thereby causing the epoxy resin to have a cloudy appearance, amine blush, surface defects, incomplete or slow curing. At this time, the exhaust fan 2 can reduce the occurrence of such situations. During operation, when the heating roller 12 rotates, the support plate 3 will rotate with the rotation of the heating roller 12. At the same time, the rotation of the support plate 3 will drive the arc-shaped wall scraper 31 to rotate along the inner wall of the stirring tank 1. When the arc-shaped wall scraper 31 rotates, the connecting rope 32 will be affected by it and drive the knocking hammer 33 to swing, so that the inner wall of the stirring tank 1 can be knocked. In this step, the inner wall of the stirring tank 1 can be knocked by the cooperation of the support plate 3 and the arc-shaped wall scraper 31. Cleaning is performed to prevent the epoxy resin from adhering to the inner wall of the mixing tank 1 when the epoxy resin is stirred, thereby easily causing insufficient stirring of the epoxy resin on the inner wall of the mixing tank 1, thereby affecting the standard of the final product. By knocking the inner wall of the mixing tank 1 with the hammer 33, the vibration caused by the knocking can be used to reduce the bubbles that may be generated during the stirring process of the epoxy resin, thereby improving the compactness of the epoxy resin and reducing surface defects. When working, when the servo motor 11 is working, it will generate a certain vibration, and at this time, the vibration will be transmitted to the spring column 41 through the fastening ring 4. The spring column 41 will expand and contract under the influence of the vibration, thereby alleviating part of the vibration and transmitting the remaining vibration to the shock-absorbing pad 42.The shock-absorbing pad 42 will further alleviate the vibration force received. This step can assist in fixing the servo motor 11 through the action of the fastening ring 4 and the spring column 41. At the same time, the spring column 41 and the shock-absorbing pad 42 can reduce the vibration, and the noise generated by the operation of the servo motor 11 can be reduced and noise can be reduced, thereby reducing the transmission of noise and reducing noise pollution. When working, the gas exhausted by the exhaust fan 2 will flow out to the outside through the sound-absorbing shutter 5. When the gas flows through the sound-absorbing shutter 5, it will rub and interfere with the window leaf 51, thereby reducing the intensity of the noise. This step can reduce the noise generated by the exhaust fan 2 when it is working through the action of the sound-absorbing shutter 5 and the window leaf 51, thereby reducing noise pollution and providing a comfortable environment for the staff. A relatively good working environment. When the exhaust fan 2 is working, the valve plate 6 will be affected by the airflow and expand, so that the gas inside the mixing tank 1 can be smoothly discharged to the outside. When the exhaust fan 2 is not working, the valve plate 6 will be in a closed state. This step is that when the epoxy resin inside the mixing tank 1 is stirred, it may be affected by the force and splashed into the exhaust fan 2, thereby polluting the exhaust fan 2 and affecting the normal operation of the exhaust fan 2. At this time, the opening of the valve plate 6 can reduce the occurrence of such situations. When working, the stirring of the epoxy resin inside the mixing tank 1 can be observed through the transparent observation plate 7. This step is that the transparent observation plate 7 can be used by the staff to determine when to stop stirring the epoxy resin. ,
