Detailed implementation manners

[0018] In order to clearly and completely describe the objectives, technical solutions of the present invention, and make the advantages more clearly understood, the following further details the embodiments of the present invention with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are some, rather than all, of the embodiments of the present invention, and are only used to explain the embodiments of the present invention, not to limit the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0019] Embodiment 1 Please refer to Figures 1 - 4 , the present invention provides a technical solution: a premixing device for a two-component curing coating, including a cover plate 1 for covering the material barrel. A rotating seat 4 is rotatably connected to the surface of the cover plate 1. A rotating shaft 5 is provided at the bottom end of the rotating seat 4. A first blade 6 and a second blade 7 are fixed to the surface of the rotating shaft 5. An aggregate groove 13 is formed on the top surface of the rotating seat 4. A collar 11 is inserted into the top of the aggregate groove 13. A second support rod 12 is fixed to the outer ring surface of the collar 11. One end of the second support rod 12 is fixed to the top surface of the cover plate 1. A material dropping port 16 is formed on the bottom surface of the aggregate groove 13. A through port 17 is formed on the surface of the rotating shaft 5. A discharge port 25 is formed on the surface of the through port 17. A material scattering port 24 is formed on the surface of the second blade 7. The material scattering port 24 communicates with the discharge port 25. In order to effectively avoid opening the cover to put additives during stirring of the materials, and avoid installing a separate feeding device, the structure of the traditional stirring shaft is optimized, so that while the stirring shaft satisfies the material stirring function, it also satisfies the function of putting additives, that is, it serves multiple purposes and is conducive to popularization and use.

[0020] Embodiment 2 On the basis of Embodiment 1, in order to fix the cover plate 1 in the material barrel containing the two-component curing coating, a sleeve frame 28 is fixed to the bottom surface of the cover plate 1. An edge groove 26 is formed on the surface of the cover plate 1. The edge groove 26 is an arc-shaped groove. There are multiple edge grooves 26, and the multiple edge grooves 26 are arranged equidistantly and equally sized around the cover plate 1. A handle rod 27 is fixed between two parallel side walls of the edge groove 26. The handle rod 27 is an arc-shaped rod. A rubber cover 29 is fixed to the inner wall of the sleeve frame 28. A plurality of screw holes are formed on the outer ring surface of the sleeve frame 28. A clamping screw 30 is screwed into the screw holes. When the clamping screw 30 is screwed into the sleeve frame 28, the sleeve frame 28 stretches the rubber cover 29 to generate elastic deformation.

[0021] Integrate the mixing device on the cover plate 1, which is convenient for turnover use after disassembly and is also convenient for adapting to different material buckets. After injecting the two raw materials of the two-component curing coating into the material bucket, cover the cover plate 1 on the material bucket. At this time, the sleeve 28 is sleeved on the top of the material bucket, and the rubber cover 29 is clamped between the sleeve 28 and the material bucket. Screw the clamping screw 30 to clamp the material bucket. At this time, the clamping screw 30 tenses the rubber cover 29 to deform, and the clamping screw 30 presses the rubber cover 29 against the surface of the material bucket, so as to increase the friction between the clamping screw 30 and the material bucket, and the resilience of the rubber cover 29 props up the clamping screw 30, making the clamping screw 30 firmly bite at the screw connection with the screw hole.

[0022] Embodiment 3 On the basis of Embodiment 2, in order to drive the rotating seat 4 to rotate and drive the rotating shaft 5 to stir the two-component curing coating in the material bucket, a reserved opening 2 is provided on the surface of the cover plate 1. The rotating seat 4 is a "work"-shaped cylinder, and a first bearing 3 is sleeved in the outer ring groove of the rotating seat 4. The outer ring of the first bearing 3 is fixed on the surface of the reserved opening 2, and the inner ring of the first bearing 3 is fixed in the outer ring groove of the rotating seat 4. The rotating shaft 5 is a "T"-shaped cylinder, and the top plate of the rotating shaft 5 is fixed on the bottom surface of the rotating seat 4 by bolts. A support plate 9 is provided above the cover plate 1. The support plate 9 is a circular ring plate structure, and a servo motor 8 is fixed on the top surface of the support plate 9. The drive shaft of the servo motor 8 passes through the inner ring opening of the support plate 9 and is fixed on the top surface of the rotating seat 4. A plurality of first support rods 10 are fixed on the outer ring surface of the support plate 9. The first support rods 10 are "L"-shaped rods, and one end of the first support rods 10 is fixed on the top surface of the cover plate 1.

[0023] After triggering the switch of the servo motor 8, the servo motor 8 drives the rotating seat 4 to rotate. A first bearing 3 is installed between the rotating seat 4 and the reserved opening 2, so as to prevent the rotating seat 4 from swinging in the reserved opening 2. Since the rotating shaft 5 is fixed at the bottom end of the rotating seat 4, the rotating seat 4 drives the rotating shaft 5 to rotate synchronously. During this process, the rotating shaft 5 drives the first blade 6 and the second blade 7 to stir the raw materials in the material bucket. The cover plate 1 covers the top of the material bucket to prevent the materials from splashing during the stirring process.

[0024] Embodiment 4 Refer to the appendix Figures 5 - 9As shown in the figure, on the basis of Embodiment III, in order to achieve the addition of additives and the replenishment of materials without opening the lid during the stirring process of the two-component curing coating in the material bucket, the aggregate chute 13 is an annular chute, the collar 11 is a "T"-shaped circular ring plate, the inner ring surface of the bottom end of the collar 11 is fixedly provided with a third bearing 15, the inner ring of the third bearing 15 is fixedly arranged on the inner ring surface of the aggregate chute 13, the outer ring surface of the bottom end of the collar 11 is sleeved and fixedly provided with a second bearing 14, the outer ring of the second bearing 14 is fixedly arranged on the outer ring surface of the aggregate chute 13, the material dropping port 16 is an arc-shaped notch, there are multiple material dropping ports 16, and the multiple material dropping ports 16 are arranged and distributed centered on the inner ring opening of the aggregate chute 13. The surface of the second bearing 14 is provided with two through holes 19. The discharge pipes of two feed pumps 18 are respectively inserted into the two through holes 19. The bottom end of the through port 17 is inserted with a support rod 20. The support rod 20 is an inverted "T"-shaped rod. The bottom plate of the support rod 20 is fixedly arranged on the bottom surface of the rotating shaft 5 through screws. The top end of the support rod 20 is fixedly provided with a storage battery 21. The top end of the storage battery 21 is fixedly provided with an electric push rod 22. The top end of the piston rod of the electric push rod 22 is fixedly provided with a sealing block 23. The height of the sealing block 23 is greater than the height of the discharge port 25. The diameter of the sealing block 23 is equal to the diameter of the through port 17. The material scattering port 24 is an "L"-shaped chute.

[0025] The rotating shaft 5 not only drives the first blade 6 and the second blade 7 to stir the materials, but also the rotating shaft 5 and the rotating seat 4 cooperate to act as a conveying structure for the additives. That is, during the stirring process of the materials, when it is necessary to add additives to the material bucket, the suction pipe of the feed pump 18 is inserted into the storage device of the additives. After triggering the switch of the feed pump 18, the feed pump 18 injects the additives into the aggregate chute 13. The additives inside the aggregate chute 13 fall into the through port 17 through the material dropping port 16. When it is necessary to scatter the additives inside the through port 17, trigger the switch of the electric push rod 22. The piston rod of the electric push rod 22 retracts. The piston rod of the electric push rod 22 drives the sealing block 23 to descend until the sealing block 23 is misaligned with the discharge port 25. Micro holes can be opened on the surface of the support rod 20 to relieve the pressure of the through port 17 when the sealing block 23 descends. After the sealing block 23 descends, it no longer blocks the discharge port 25. The additives inside the through port 17 flow out from the discharge port 25 along the material scattering port 24 and drip onto the stirred materials; in the same way, the suction pipe of the feed pump 18 can also be inserted into the storage bucket filled with the two-component curing coating. Two feed pumps 18 are provided to meet the simultaneous replenishment of materials to the material bucket during the stirring process.

[0026] Embodiment V On the basis of Embodiment IV, a usage method of the two-component curing coating premixing device is proposed, including the following steps: Step 1: Integrate the mixing device on the cover plate 1, which is convenient for turnover use after disassembly and is also convenient for adapting to different material buckets. After injecting the two raw materials of the two-component curing coating into the material bucket, cover the material bucket with the cover plate 1. At this time, the sleeve 28 is sleeved on the top of the material bucket, and the rubber cover 29 is clamped between the sleeve 28 and the material bucket. Screw the clamping screw 30 to clamp the material bucket. At this time, the clamping screw 30 tensions the rubber cover 29 to deform, and the clamping screw 30 presses the rubber cover 29 against the surface of the material bucket, so as to increase the friction between the clamping screw 30 and the material bucket, and the resilience of the rubber cover 29 supports the clamping screw 30, making the clamping screw 30 and the screw hole screwed firmly; Step 2: After triggering the switch of the servo motor 8, the servo motor 8 drives the rotating seat 4 to rotate. A bearing 3 is installed between the rotating seat 4 and the reserved port 2 to prevent the rotating seat 4 from swinging in the reserved port 2. Since the rotating shaft 5 is fixed at the bottom end of the rotating seat 4, the rotating seat 4 drives the rotating shaft 5 to rotate synchronously. During this process, the rotating shaft 5 drives the blade 6 and the blade 7 to stir the raw materials in the material bucket, and the cover plate 1 covers the top of the material bucket to prevent the materials from splashing during the stirring process; Step 3: The rotating shaft 5 not only drives the blade 6 and the blade 7 to stir the materials, but also the rotating shaft 5 and the rotating seat 4 act as a conveying structure for the additive. That is, when adding an additive to the material bucket during the stirring process of the materials, insert the suction pipe of the feeding pump 18 into the storage device of the additive. After triggering the switch of the feeding pump 18, the feeding pump 18 injects the additive into the aggregate tank 13. The additive inside the aggregate tank 13 falls into the through hole 17 through the material dropping port 16. When it is necessary to disperse the additive inside the through hole 17, trigger the switch of the electric push rod 22. The piston rod of the electric push rod 22 retracts, and the piston rod of the electric push rod 22 drives the sealing block 23 to fall until the sealing block 23 is misaligned with the discharge port 25. Micropores can be opened on the surface of the support rod 20 to relieve the pressure of the through hole 17 when the sealing block 23 descends. After the sealing block 23 falls, it no longer blocks the discharge port 25, and the additive inside the through hole 17 flows out from the discharge port 25 along the discharge port 24 and drips on the stirred materials; In the same way, the suction pipe of the feeding pump 18 can also be inserted into the storage bucket containing the two-component curing coating. Two feeding pumps 18 are provided to meet the need to supplement materials to the material bucket during the stirring process at the same time; Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
