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.
[0018] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process.
[0019] At present, when the coating of centrifugal casting pipe is stirred, tiny bubbles are easily left inside the coating. When it is directly applied to the surface of the casting pipe, the bubbles will affect the coating quality of the casting pipe, thereby reducing the production quality of the casting pipe and making the production qualification rate low.
[0020] In view of this, the utility model provides a centrifugal cast pipe paint mixer, which can effectively remove bubbles inside the paint after stirring through the cooperation of a tank body, a rubber hammer, a nylon rope, a diagonal rod, a torsion spring, a block and an exhaust pipe, thereby improving the production quality of the paint and avoiding the problem of reduced quality of cast pipe coating due to the presence of tiny bubbles inside the paint. Therefore, the production quality of the cast pipe can be improved and it is convenient for the staff to use it.
[0021] Embodiment 1: Figure 1 , 2, 3 and 4 show that the centrifugal cast tube paint mixer comprises a tank body 1, a foot 3 is installed at the bottom of the tank body 1, a cover body 2 is installed at the top of the tank body 1, a servo motor 4 is detachably connected to the bottom of the tank body 1, a vertical rod 5 is detachably connected to the output end of the servo motor 4, the outer wall of the vertical rod 5 is rotatably connected to the inner wall of the tank body 1 through a sealed bearing, a stirring rod 6 is installed above the outer wall of the vertical rod 5, a feed pipe 17 is installed on one side of the cover body 2, a discharge pipe 16 is installed below one side of the tank body 1, and a processing device is arranged below the tank body 1; the processing device comprises a rubber hammer 10, a nylon rope 1 1. An inclined rod 8, a torsion spring 9, a block 12 and an exhaust pipe 18; two inclined rods 8 are provided, and the tops of the two inclined rods 8 are rotatably connected to the bottom of the tank body 1, rubber hammers 10 are installed at the ends of the two inclined rods 8, and the outer walls of the two rubber hammers 10 are tightly pressed against the bottom of the tank body 1, nylon ropes 11 are installed on the outer walls of the two inclined rods 8, and the outer walls of the two inclined rods 8 are installed with torsion springs 9 fixedly connected to the bottom of the tank body 1, and a block 12 fixedly connected to the outer wall of the tank body 1 is provided above the inclined rod 8, and an exhaust pipe 18 connected to the inner wall of the tank body 1 is provided on one side of the block 12;
[0022] In the specific implementation process, it is worth pointing out that the model of the servo motor 4 is ECMA-E11320RS. The servo motor 4 can drive the stirring rod 6 to stir the paint through the vertical rod 5. The nylon rope 11 can be wound around the outer wall of the block 12 for fixing. Pulling the nylon rope 11 can drive the inclined rod 8 to move, thereby changing the angle of the rubber hammer 10. At this time, the torsion spring 9 begins to deform. When the nylon rope 11 is loosened, due to the elastic force of the torsion spring 9, the rubber hammer 10 can knock on the bottom of the tank body 1, thereby shaking out the bubbles inside the paint.
[0023] Furthermore, a first scraper 7 is installed at the end of the stirring rod 6, and the outer wall of the first scraper 7 is movably connected to the inner wall of the tank body 1;
[0024] In the specific implementation process, it is worth pointing out that the first scraper 7 can clean the paint hanging on the wall;
[0025] Specifically, when using the centrifugal cast tube paint mixer, the staff first injects the paint into the interior of the tank body 1 through the feed pipe 17, and then the staff turns on the external power supply of the servo motor 4. At this time, the servo motor 4 can drive the vertical rod 5 to rotate, and then the stirring rod 6 can be used to stir the paint. After stirring, the paint is discharged to the bottom of the interior of the tank body 1, and then the staff pulls the nylon rope 11. At this time, the nylon rope 11 drives the inclined rod 8 to rotate along the bottom of the tank body 1, and at the same time drives the torsion spring 9 to deform. When the nylon rope 11 is loosened, the torsion spring 9 will drive the inclined rod 8 back to its original position, so that the rubber hammer 10 can knock on the bottom of the tank body 1, and then the bubbles inside the paint can be shaken out to complete the processing work.

[0028] Specifically, based on the above-mentioned embodiment 1, when discharging, the staff turns on the external power supply of the servo motor 4, and the servo motor 4 can drive the second scraper 24 to rotate through the vertical rod 5, and open the discharge pipe 16 at the same time. At this time, as the second scraper 24 rotates, the paint can be more conveniently discharged from the discharge pipe 16 to the interior of the tank body 1.
[0029] Embodiment 3: By Figure 2 It can be seen that an isolation device is provided inside the tank body 1; the isolation device includes a partition 13, an electric push rod 14 and a horizontal plate 15; the outer wall of the partition 13 is fixedly connected to the inner wall of the tank body 1, and the inner wall of the partition 13 is rotatably connected to the outer wall of the vertical rod 5 through a sealed bearing, the top of the partition 13 is movably connected to the bottom of the stirring rod 6, the inner wall of the partition 13 is installed with an electric push rod 14, and the output end of the electric push rod 14 is installed with a horizontal plate 15 movably connected to the inner wall of the partition 13;
[0030] In the specific implementation process, it is worth pointing out that the model of the electric push rod 14 is not specifically limited, and it only needs to meet the use requirements, and the horizontal plate 15 and the partition 13 should be sealed to prevent the paint from affecting the electric push rod 14. The specific method is not limited, and it only needs to meet the use requirements.
[0031] Specifically, based on the above-mentioned embodiment 1, when it is necessary to guide the paint to the lower part of the interior of the tank body 1, the staff turns on the external power supply of the electric push rod 14, and the electric push rod 14 can drive the cross plate 15 to move along the inner wall of the partition 13. When the cross plate 15 moves to a certain position, the partition 13 can be opened, and the paint can fall to the lower part of the interior of the tank body 1.
[0032] Embodiment 4: By Figure 2 and 4It can be seen that a cleaning device is provided above the tank body 1; the cleaning device comprises a water pipe 21, a conduit 20, a nozzle 23 and a bracket 22; the outer wall of the conduit 20 is fixedly connected to the inner wall of the cover body 2, the bottom of the conduit 20 is connected to the water pipe 21, the bottom of the water pipe 21 is equidistantly installed with nozzles 23, and both sides of the water pipe 21 are installed with brackets 22 fixedly connected to the bottom of the cover body 2;
[0033] In the specific implementation process, it is worth pointing out that the conduit 20 is connected to the external water supply device, and then the external water source can be sprayed to the inside of the tank body 1 through the nozzle 23, so as to cooperate with the first scraper 7, the second scraper 24, the cleaning plate 19 and the stirring rod 6 and other components to perform rapid cleaning work;
[0034] Specifically, on the basis of the above-mentioned embodiments one, two and three, when cleaning is needed, the staff turns on the external water supply device connected to the conduit 20, and the external water source can be transported to the inside of the water pipe 21 through the conduit 20, and then sprayed from the nozzle 23 to the inside of the tank body 1. Then the staff turns on the external power supply of the servo motor 4, and the cleaning work can be achieved through the cooperation with the first scraper 7, the second scraper 24, the cleaning plate 19 and the stirring rod 6 and other components.
[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
