As shown in fig. 9 and fig. 10, the device further includes a proportioning adjusting mechanism for adjusting a mixing ratio of the two components, the proportioning adjusting mechanism is disposed on the first connecting pipe 113 on the right side, the proportioning adjusting mechanism includes a second connecting pipe 401, the second connecting pipe 401 is communicated with the first connecting pipe 113 on the right side, a blocking piece 402 is slidably connected in the second connecting pipe 401, a sixth rotating rod 403 is connected in the second connecting pipe 401 in a threaded manner, one end of the sixth rotating rod 403 is fixedly connected with the blocking piece 402, the blocking piece 402 is adjusted to move back and forth by rotating the sixth rotating rod 403, and an effective cross-sectional area of glue solution passing through in the first connecting pipe 113 on the right side is adjusted.
When the polyurea glue solution needs to be prepared, the worker rotates the sixth rotating rod 403 to adjust the blocking piece 402 to move back and forth, so that the glue solution in the right first connecting pipe 113 can be adjusted to effectively pass through the cross sectional area until the target proportion is adjusted.
The steps are repeated until the worker starts the first driving part 103, the first driving part 103 drives the two third rotating rods 201 to rotate through the belt pulley and the belt, the two third rotating rods 201 respectively drive the adjacent second stirring parts 202 to rotate, the glue solution in the two component storage shells 112 is stirred, and particles in the glue solution adhere to the wall under the action of centrifugal force, so that the particles in the two components of glue A and glue B are prevented from precipitating at the lower part after being placed for a long time.
The two third rotating rods 201 respectively drive the adjacent fourth rotating rods 204 to rotate through the cylindrical gear 205, and under the action of the two limiting rods 206, the two first mixing parts 207 move up and down in a reciprocating manner.
When the two first mixing parts 207 move upwards, the four second mixing parts 210 cannot rotate downwards under the limiting action of the adjacent first connecting parts 208, and the four second mixing parts 210 respectively move upwards along with the adjacent first mixing parts 207 and drive adherent particles in the glue solution to move upwards, so that the particles in the glue solution are prevented from being deposited at the inner lower part of the component storage shell 112.
When the four one-way gears 211 move upward, the one-way gears 211 at this time cannot drive the adjacent second mixing member 210 to rotate.
When the four second mixing members 210 move downwards, the four second mixing members 210 are separated from the liquid level of the glue solution, when the four second mixing members 210 move downwards to be in contact with the liquid level of the glue solution, under the buoyancy action of the glue solution, the four second mixing members 210 rotate upwards along the respective hinge rods 209 until the four second mixing members do not rotate under the limiting action of the adjacent first mixing members 207, at the moment, the two second mixing members 210 in the same component storage shell 112 are in an outer splayed shape, the glue solution on the lower side of the two second mixing members is extruded, particles attached to the wall in the glue solution are guided to enter the central part of the glue solution, the particles in the glue solution are uniformly distributed, and the influence on the reaction time of mixing the glue A and the glue B to form polyurea glue solution and the performance of the prepared polyurea due to different densities of the glue solutions in the glue A and the glue B is avoided.
When the four one-way gears 211 move downwards to be respectively engaged with the adjacent second toothed plates 212, the four second toothed plates 212 respectively drive the adjacent second mixing parts 210 to reset to the initial state through the adjacent one-way gears 211, and the process is repeated in such a circulating way, so that particles in the glue solution are uniformly distributed.
When the stirring time is enough for the particles in the glue A and the glue B to be uniformly distributed, the worker opens the electromagnetic valves and the screw pumps at the communication positions of the two first connecting pipes 113 and the adjacent component storage shell 112, and the screw pumps convey the glue A and the glue B into the polyurea preparation shell 102 through the respective adjacent first connecting pipes 113 until the volume of the glue A and the glue B entering the polyurea preparation shell 102 reaches a set value, and closes the electromagnetic valves at the communication positions of the two first connecting pipes 113 and the adjacent component storage shell 112.
In the process, the volume of the glue B entering the polyurea preparation shell 102 in unit time is adjusted through the blocking piece 402, so that the glue A and the glue B entering the polyurea preparation shell 102 in unit time are mixed in proportion to obtain the polyurea glue solution with the target effect.
The above steps are repeated until the glue A and the glue B entering the polyurea preparation shell 102 are mixed under the stirring action of the first stirring piece 105, so that the glue A and the glue B are fully mixed and react to generate polyurea.
In the process, the first rotating rod 104 drives the third bevel gear 306 to rotate reversely through the first bevel gear 302 and the second bevel gear 304, the third bevel gear 306 drives the third stirring part 301 to rotate reversely through the second connecting part 305, the glue A and the glue B entering the polyurea preparation shell 102 are stirred, and the rotation of the first stirring part 105 and the reverse rotation of the third stirring part 301 are matched, so that the glue A and the glue B entering the polyurea preparation shell 102 are mixed uniformly.
In the process, the mesh in the sieve holes of the first stirring piece 105 and the third stirring piece 301 are broken, bubbles in the polyurea glue solution are crushed in the rotating process, and the crushed bubbles are discharged through the four-way communication pipe 114 and the vacuum exhaust device to eliminate the bubbles in the polyurea glue solution.
After the glue A and the glue B in the polyurea preparation shell 102 are uniformly mixed, a worker opens the electromagnetic valve in the through hole of the polyurea preparation shell 102 and collects the generated polyurea glue solution by using a container, and closes the electromagnetic valve in the through hole of the polyurea preparation shell 102 until the polyurea glue solution in the polyurea preparation shell 102 is emptied.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the present invention, and any modifications, equivalents, improvements and the like made within the spirit and principle of the present invention should be included in the scope of the present invention.
