DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0028] In order to further understand the content of the present application, the present application will be described in detail with reference to the drawings.

[0029] In combination with Figures 1-6 The safety preparation device of the modified composite surface glue comprises a stirring barrel 1, a mixing bin 3 connected to the upper end of the bottom wall of the stirring barrel 1, and the side walls of the stirring barrel 1 and the side walls of the mixing bin 3 are both of a segmented structure and jointly form a complete enclosing structure. In the prior art, when mixing glue, the stirring paddle is driven to rotate along a single shaft, and in order to improve the stirring efficiency, the rotation speed of the motor is changed. However, after the rotation speed of the motor is improved, the glue will splash due to the centrifugal force during rotation, which will cause a large amount of glue to adhere to the inner wall of the stirring device, and the post-processing will be more complicated.

[0030] In addition, when rotating at high speed, the stirring paddle will drive the glue to rotate synchronously in the barrel body, so that the stirring effect will be poor. If the synchronous rotation condition is changed, the motor needs to be forward and reverse, which will cause the problem of glue splashing described above, and the glue at the bottom of the barrel cannot be fully stirred, and the interaction effect of the upper and lower layers of glue is poor.

[0031] The inner wall of the stirring barrel 1 is connected with a tumbling assembly 4, the tumbling assembly 4 comprises a transmission wheel 41, the inside of the stirring barrel 1 is embeddedly connected with the transmission wheel 41, the surface of the transmission wheel 41 is wrapped with a transmission belt 42, the transmission belt 42 is looped around the upper end of the transmission wheel 41 to form a conveying belt structure, the surface of the transmission belt 42 is uniformly distributed with spoiler plates 43, the distance kept between each group of spoiler plates 43 is the same, in order to reduce the rotating speed of the driving motor 2, the ideal stirring effect can also be kept, the transmission wheel 41 is driven to rotate by the driving motor 2, when the transmission wheel 41 rotates, it will preferentially drive one group of transmission belts 42 to rotate, the rotation of the transmission belt 42 will drive the spoiler plates 43 to rotate, after rotating, the colloid is mixed by the spoiler plates 43, since the movement direction of the spoiler plates 43 is designed from the bottom end to the top end, in this way, when rotating, the colloid at the bottom layer can be turned and stirred to the upper layer, then the colloid at the upper layer will be stirred to the bottom layer under the action of the spoiler plates 43, under such stirring, the mixing between the colloid at the upper layer and the bottom layer can be accelerated, since the rotating speed is slow, the colloid will not splash, and since the rotating direction is different from the prior art, it does not rotate along the shaft, thus the colloid will not appear synchronous rotation.

[0032] The transmission wheel 41 and the transmission belt 42 are provided with two groups, and the two groups of transmission wheels 41 and the two groups of transmission belts 42 are arranged on the inner wall of the stirring barrel 1. The two groups of transmission wheels 41 are connected through the connecting rod 10, the driving gear 8 and the driven gear 9. The surface of the transmission belt 42 is connected with the spoiler 43. The spoiler 43 is a metal sheet with an arc-shaped outer edge. The side of the spoiler 43 away from the transmission belt 42 is higher than the side connected with the transmission belt 42. The spoiler 43 is inclined and arranged at the upper end of the transmission belt 42. The spoiler 43 is symmetrically arranged in the interior of the stirring barrel 1. The outer wall of the stirring barrel 1 is fixedly connected with the driving motor 2. The output end of the driving motor 2 is embedded into the interior of the stirring barrel 1 and connected to one end of the transmission shaft 7. The transmission shaft 7 is embedded into the interior of the transmission wheel 41. The other end of the transmission shaft 7 is connected with the connecting rod 10. The two ends of the connecting rod 10 are fixedly connected with the eccentric shaft block 6. The bottom end of the eccentric shaft block 6 abuts against the edges of the partition plate 5 on both sides. The bottom end of the eccentric shaft block 6 is arc-shaped. The upper end of the connecting rod 10 is connected with the driving gear 8. The interior of the stirring barrel 1 is connected with another group of transmission wheels 41. The center shaft of the other group is connected with a group of driven gears 9. The driving gear 8 is lower than the driven gear 9 and they are engaged with each other. The interior of the mixing bin 3 is embedded with the separation groove 12. The upper end of the separation groove 12 is provided with a through hole. One side of the spoiler 43 is attached to the outer wall of the separation groove 12. The longitudinal position of the attached part of the spoiler 43 and the separation groove 12 is not provided with a through hole. The upper end of the separation groove 12 is connected with the partition plate 5. The partition plate 5 is inclinedly embedded into the interior of the separation groove 12. The separation groove 12 and the partition plate 5 are connected through the spring 11. When the spoiler 43 moves upward, the height of the side of the spoiler 43 close to the separation groove 12 is lower than the height of the other side. The surface of the spoiler 43 and the separation groove 12 are slidingly connected. In order to improve the stirring effect, the movement direction of the colloid inside is inconsistent, and the mixing effect between the colloids is more excellent. The rotation directions of the two groups of transmission wheels 41, the transmission belts 42 and the spoilers 43 are opposite. The movement direction of the spoilers 43 on the same side will also change, thereby accelerating the mixing of the colloids.

[0033] In addition, the coagulation block inside the colloid can be conveniently treated. The colloid can be transferred to the upper end of the partition plate 5 through the spoiler 43. Then the coagulation block of the colloid is separated out through the partition plate 5. The colloid without coagulation block will fall into the interior of the separation groove 12. Finally, the colloid will penetrate out of the separation groove 12 through the through holes on both sides again and be repeatedly stirred and mixed through the transmission belt 42 and the spoiler 43.

[0034] A modified composite surface glue preparation method, first, the glue mixture is added to the inside of the stirring barrel 1, the glue is stirred through the transmission belt 42 and the spoiler 43, the bottom end of the glue is lifted up, the surface of the glue is mixed to the bottom end, the glue on the outer wall of the separation groove 12 is scraped off and falls to the upper end of the partition plate 5 and penetrates into the inside of the separation groove 12, finally, the glue is penetrated out of the separation groove 12 again and repeatedly stirred through the rotation of the transmission belt 42 and the spoiler 43, the glue mixing preparation is realized.
