Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, and in particular relates to a coating mixing device for building waterproof construction. Background Art

[0002] Building waterproof construction coating is a viscous liquid polymer synthetic material with no fixed shape at room temperature. After coating, it can form a tough waterproof coating film on the surface of the base layer through the volatilization of solvents or evaporation of water or reaction curing. Before use, the coating usually needs to be mixed with some special fusing agents.

[0003] The prior art discloses a building waterproof construction paint mixing device (CN212039919U), which includes a cylinder; support feet are fixedly installed on the left and right sides of the cylinder, and rotating motors a are fixedly installed on the left and right sides of the cylinder. The motor shafts of the two rotating motors a respectively pass through the left and right sides of the cylinder and rotating plates are fixedly installed on the outer circles. Scrapers are fixedly installed on the upper and lower sides of the two rotating plates; a rotating motor b is fixedly installed on the middle end of the top side of the cylinder.

[0004] After searching, it was found that the existing technology uses a joint stirring rod to stir the material during use. However, this design has certain disadvantages in use. The interface between the motor and the stirring rod has poor sealing, and the stirring direction is on both sides of the cylinder, which makes it impossible for the material in the middle of the cylinder to be flipped up and down, resulting in uneven mixing. In addition, considering that some materials have strong viscosity and are easy to adhere to the inner wall of the cylinder during mixing, the stirring rods on both sides of the device make it impossible for the attached materials on the inner wall of the cylinder to be effectively mixed, which causes a certain error in the material ratio, thereby affecting the mixing effect of the device.

[0005] In view of this, the present utility model is proposed. Utility Model Content

[0028] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.

[0029] A device for mixing building waterproof coatings, such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5As shown, it includes a cylinder 10, and a cylinder cover 12 is fixedly installed on the top surface of the cylinder 10 by bolts; a driving structure, the driving structure is movably arranged on the top surface of the cylinder cover 12, the driving structure includes a slave bevel gear 15, a gear 20, a rack 21, a fan gear 22 and a main bevel gear 23, the rack 21 and the fan gear 22 are fixedly arranged on the bottom surface of the slave bevel gear 15, the slave bevel gear 15 and the main bevel gear 23 are rotatably arranged on the top surface of the cylinder cover 12, the slave bevel gear 15 is transmitted below the main bevel gear 23, and the gear 20 is transmitted between the rack 21 and the fan gear 22; a mixing structure, the mixing structure is rotatably arranged in the cylinder 10, the mixing structure includes a stirring screw 17, a stirring scraper 18 and a grinding ball 19, the stirring screw 17 is fixedly arranged above the grinding ball 19, the stirring scraper 18 is fixedly arranged on the curved surface of the stirring screw 17, and the stirring screw 17 is rotatably arranged between the cylinder 10 and the cylinder cover 12; as shown Figure 1 As shown, a discharge pipe 11 is fixedly provided on the bottom surface of the cylinder 10, and a feed pipe 13 is fixedly provided on the top surface of the cylinder cover 12 at a position deviated from the center of the circle.

[0030] Specifically, the device is provided with a driving structure and a stirring screw 17, and uses the rack 21 and the fan gear 22 to respectively engage the gear 20 to achieve two two-way back and forth rotations, thereby driving the stirring screw 17 to mix the material while feeding and stirring it up and down. The reciprocating switching in the two directions cooperates with the grinding balls 19 to grind larger particles so that the material can be mixed more evenly. By providing a stirring scraper 18, the driving structure is used to drive the mixing structure, so that the stirring screw 17 stirs and feeds the material in a stirring and feeding manner, the stirring scraper 18 scrapes the inner wall of the cylinder 10 back and forth, and the grinding balls 19 grind the larger particles near the discharge pipe 11. This not only processes the material attached to the wall of the cylinder 10, but also improves the mixing effect of the device.

[0031] like Figure 1 and Figure 2 As shown, a mixing shaft 14 is rotatably provided in the cylinder cover 12, a stirring screw 17 is fixedly connected to the curved surface of the mixing shaft 14, a grinding ball 19 is fixedly connected to the bottom end of the mixing shaft 14, and the grinding ball 19 rotates in the discharge pipe 11, and a plurality of stirring scrapers 18 are provided, and the plurality of stirring scrapers 18 surround the stirring screw 17 on the curved surface side close to the cylinder body 10; Figure 2 and Figure 3 As shown, the stirring scraper 18 is composed of a square column and an arc-shaped block. The square column is fixedly connected to the stirring spiral 17. The side of the arc-shaped block close to the wall of the cylinder 10 is an arc surface. One end of the stirring scraper 18 is provided with a sharp corner for scraping the wall of the cylinder 10; Figure 4 As shown, the discharge pipe 11 and the cylinder 10 are directly opened with an arc-shaped opening, which corresponds to the shape of the grinding ball 19, and the grinding ball 19 rotates in the arc-shaped opening.

[0032] Specifically, a circular hole is opened in the center of the cylinder cover 12, and a bearing is arranged in the circular hole. The cylinder cover 12 is rotatably connected to the mixing shaft 14 through the bearing in the circular hole. When the mixing shaft 14 rotates, the stirring screw 17 conveys and stirs the material in the cylinder body 10. At the same time, a plurality of stirring scrapers 18 distributed in a curve on the curved surface of the stirring screw 17 will scratch the inner wall surface of the cylinder body 10 to scrape off the attached material. After mixing, the material reaches the grinding ball 19, passes through the top surface of the grinding ball 19 and slides down to the arc-shaped mouth. The grinding ball 19 grinds the material in the arc-shaped mouth to ensure the fineness of the material. Finally, the fine material is discharged through the arc-shaped mouth and the discharge pipe 11.

[0033] like Figure 3 and Figure 5 As shown, the top surface of the mixing shaft 14 is fixedly connected to the gear 20, and the sector gear 22 is rotatably arranged on the top surface of the cylinder cover 12, and the gear 20 meshes with the transmission annular rack 21 and the sector gear 22; Figure 3 and Figure 4 As shown, a support 24 is fixedly provided on the top surface of the cylinder cover 12 , and a motor 16 is fixedly installed on the inner side of the support 24 . The output end of the motor 16 is connected to the main bevel gear 23 , and the main bevel gear 23 is engaged with the slave bevel gear 15 .

[0034] Specifically, a cylinder is fixedly provided on the top surface of the cylinder cover 12 at a position away from the center of the circle, and the sector gear 22 rotates around the cylinder. The motor 16 is started, and the motor 16 drives the main bevel gear 23 to engage with the slave bevel gear 15. At this time, the rotation of the slave bevel gear 15 drives the rotation of the rack 21 and the sector gear 22. The saw teeth of the sector gear 22 and the rack 21 are in the same direction, but the saw tooth arc length of the sector gear 22 is smaller than the saw tooth arc length of the rack 21. Therefore, when the rack 21 is engaged with the gear 20, the saw tooth side of the sector gear 22 is away from the gear 20. On the contrary, when the sector gear 22 engages with the gear 20, the rack 21 moves away from the gear 20. As this meshing mode continues, the gear 20 is affected by the arc length of the rack 21 to achieve multiple rotations, and then is affected by the arc length of the sector gear 22 to achieve reverse rotation. At this time, the mixing shaft 14 connected to the bottom surface of the gear 20 is affected in the same way, driving the stirring bolt 17 to stir the material up and down for a short time during the reverse process. Similarly, the stirring scraper 18 will also achieve a short distance of reciprocating scraping during this reverse process.

Furthermore, under the guidance of the present invention, these features and embodiments may be modified to suit specific circumstances and materials without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are intended to be protected by the present invention.
