Abstract
Description

[0002] In the field of construction and waterproof engineering, the quality and performance of waterproof coatings play a vital role in the waterproof effect. In the preparation process of waterproof coatings, the full and uniform mixing of liquid and powder is the key link to ensure the quality of the coating. The common stirring method is simple blade stirring. The stirring range of this stirring method is limited, which easily leads to uneven stirring of liquid and powder in the container. In addition, during the blade stirring process, the stirring degree of the upper and lower parts of the barrel is not consistent due to the fixed stirring blades. Based on this, we designed a method that can achieve mixing and stirring through the rotation of the disturbance bracket during the working process, and the disturbance bracket can move up and down in this process, thereby enhancing the uniformity of mixing.

DETAILED DESCRIPTION
[0022] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail with reference to the accompanying drawings. It is hereby stated that the directional words such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the utility model are only based on the accompanying drawings of the utility model, and are not specific limitations of the utility model.
[0023] like Figure 1-Figure 6 As shown, a waterproof coating liquid and powder mixing and stirring device comprises a fixed base 1, a material guide bracket 7, a lifting mechanism 4 and a stirring mechanism 5. The upper part of the fixed base 1 is provided with a material guide bracket 7, and the upper part of the material guide bracket 7 is provided with a stirring barrel 10. The lifting mechanism 4 and the stirring mechanism 5 are provided on one side of the material guide bracket 7; the lifting mechanism 4 comprises a first connecting rod 401, a second connecting rod 402, a rack 404, a first rotating shaft 406 and a gear 405. The second connecting rod 402 slides with the first sliding groove inside the first connecting rod 401 through the first sliding bars 403 on both sides. The second connecting rod 402 is dynamically connected, a rack 404 is provided on the second connecting rod 402, and the rack 404 is meshed with the gear 405 on the first rotating shaft 406; the second connecting rod 402 is provided with a stirring mechanism 5, the stirring mechanism 5 includes a lifting assembly, a sliding table 501, a third connecting rod 506, a third driving motor 507 and a disturbance frame 508, a sliding table 501 is provided inside the second connecting rod 402, and the sliding table 501 is provided with a third connecting rod 506 and a third driving motor 507, and the output shaft of the third driving motor 507 is connected to the disturbance frame 508.
[0024] It should be noted that, in order to facilitate the entry and exit of the barrel 10, we have designed a material guide bracket 7 for placing the barrel 10, which can be slid out through the upper roller 9, and a lifting mechanism 4 is arranged on the upper part of the fixed base 1, which can drive the entire first rotating shaft 406 to rotate through the first driving motor, and then drive the second connecting rod 402 to be lifted and lowered through the gear 405. The advantage of this design is that the entire stirring mechanism 5 can be lifted during the introduction of the barrel 10 to prevent interference between the two.
[0025] It should be further explained that, in order to achieve stirring, we have designed a stirring mechanism 5, wherein a disturbance frame 508 is provided on the third connecting rod 506, which is driven by a third driving motor to realize the rotation of the disturbance frame, thereby achieving stirring and mixing inside the barrel 10.
[0026] like Figure 1-Figure 6 As shown, the lifting assembly includes a fourth connecting rod 502 connected to the bottom of the sliding table 501, an auxiliary rotating wheel 503, an eccentric wheel 504 and a second driving motor 505. A second rotating shaft is arranged on the second connecting rod 402, and an eccentric wheel 504 is arranged on the second rotating shaft. The eccentric wheel 504 is arranged at the junction of the auxiliary rotating wheel 503 on the fourth connecting rod 502; the second rotating shaft is connected to the second driving motor 505 through a coupling; the first rotating shaft 406 is arranged on the fixed base 1 through a connecting support 407, and the first rotating shaft 406 is connected to the first driving motor through a coupling; a plurality of rollers 9 are arranged on the upper part of the material guiding bracket 7.
[0027] It should be noted that in order to achieve the lifting and lowering of the disturbance frame during the rotation process, we designed a lifting assembly, which drives the sliding table to reciprocate and lift in the second connecting rod through the eccentric wheel and the fourth connecting rod, thereby improving the uniformity of mixing.
[0028] It should be further explained that the advantage of this lifting structure design is that the disturbance frame can continuously move up and down during the rotation process, so the rotation point is not unique, which can increase the stirring range, reduce the generation of stirring dead angles, and improve the stirring work efficiency.
[0029] like Figure 1-Figure 6 As shown, limiting mechanisms 8 are arranged on both sides of the material guiding bracket 7. The limiting mechanisms 8 include a force arm 801, an electric push cylinder 802 and a limiting ring 803. The force arm 801 is provided with an electric push cylinder 802, and the output shaft of the electric push cylinder 802 is connected to the limiting ring 803.
[0030] It should be noted that the setting of the limiting mechanism 8 has the advantage that after the barrel 10 is introduced, the limiting ring 803 can be driven by the electric push cylinder 802 to fix the barrel 10 to prevent movement during operation.
[0031] like Figure 1-Figure 6 As shown, it also includes a feeding mechanism 6, which includes a connecting bracket 601 and a feeding hopper 602. The feeding hopper 602 is arranged on the fixed base 1 through the connecting bracket 601; a pull rod 2 is arranged on the upper part of the fixed base 1, and a flexible rubber sleeve 3 is arranged on the pull rod 2.
[0032] It should be noted that the provision of the feeding mechanism 6 facilitates the liquid material, coating material and powder material to enter the barrel 10 in batches, and then cooperates with the stirring mechanism 5 to complete the stirring.
[0033] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the purpose of the present invention.
