It includes a spraying bracket, an equipment box fixedly installed on one side of the spraying bracket, and a coating tank fixedly installed on the other side of the spraying bracket. A top cover is fixedly installed on the top of the coating tank. A mixing shell is fixedly installed on the top of the top cover, and a drive chamber is opened inside the mixing shell.

Description

Technical Field

[0001] This utility model relates to the technical field of waterproof coating construction equipment, and in particular to a spraying device for waterproof coating construction. Background Technology

[0002] The waterproof coating spraying device is a specialized piece of equipment integrating coating storage, mixing, pressurization, and atomization functions. It is used to uniformly spray liquid waterproof coatings onto building substrates (such as roofs, walls, and basements) in a high-pressure spray format. A power system drives a mixing mechanism to prevent coating sedimentation. After being pressurized by a pump, the coating is sprayed at high speed from the nozzle, atomizing into fine particles that adhere to the substrate, forming a continuous waterproof membrane. This device is compatible with various waterproof coatings, including water-based, oil-based, and solvent-based ones, significantly improving construction efficiency and coating uniformity, and is widely used in building waterproofing projects.

[0003] Existing spraying equipment typically stores paint in paint tanks. Paint is usually composed of pigments, fillers, resins, solvents, and other components, which have different densities. Under prolonged static conditions, the denser pigments and fillers will gradually sink, while the less dense resins and solvents will rise, resulting in obvious stratification of the paint. This affects the uniformity of subsequent spraying and the overall spraying effect.

[0004] Therefore, we propose a spraying device for waterproof coating application to solve the above problems. Utility Model Content

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A spraying device for waterproof coating application includes a spraying bracket, an equipment box fixedly installed on one side of the spraying bracket, a paint tank fixedly installed on the other side of the spraying bracket, a top cover fixedly installed on the top of the paint tank, and a mixing shell fixedly installed on the top of the top cover, with a drive chamber opened inside the mixing shell.

[0007] Specifically, a pressure pump is fixedly installed on the top of the spraying bracket, and a connecting pipe is fixedly installed on the input end of the pressure pump, which can transport the paint in the paint tank to the spraying equipment.

[0008] Specifically, an electrically controlled valve is fixedly installed at the bottom of the paint tank, and the other end of the connecting pipe is connected to the electrically controlled valve to facilitate control of the paint flow rate.

[0009] Specifically, the bottom of the spraying bracket is fixedly equipped with four evenly distributed casters to facilitate the movement of the equipment.

[0010] Specifically, a drive bevel gear is rotatably mounted on one inner wall of the drive chamber, and a forward bevel gear and a reverse bevel gear are rotatably mounted on the upper and lower inner walls of the drive chamber, respectively. The drive bevel gear meshes with the forward and reverse bevel gears. A motor slot is provided inside the stirring shell, and a servo motor is fixedly mounted on one inner wall of the motor slot. The output shaft of the servo motor is fixedly connected to the drive bevel gear, and the drive bevel gear can be driven to rotate by the servo motor.

[0011] Specifically, an eccentric shaft is fixedly installed at the bottom of the forward bevel gear, and a dispersing shaft is fixedly installed at the bottom of the reverse bevel gear. The dispersing shaft extends out of the stirring shell and rotates through the top cover. The eccentric shaft rotates through the reverse bevel gear and the dispersing shaft.

[0012] Specifically, a dispersion disc is fixedly installed on the outer side of the dispersion shaft, which can shear and break up clumps or bubbles floating on the surface.

[0013] Specifically, the outer side of the eccentric shaft is fixedly fitted with an anchor-type stirring blade and two paddle-type stirring blades. The blades of the two paddle-type stirring blades are inclined to facilitate the agitation of the coating.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: through the set stirring mechanism, the anchor-type stirring blade, the paddle-type stirring blade and the dispersion plate are set up to cover the upper, middle, lower and edge areas of the paint tank, forming a three-dimensional stirring cycle, which completely solves the problem of many dead corners in the stirring of a single blade and the difficulty in turning over the sediment. In addition, through the set eccentric shaft, the anchor-type stirring blade and the paddle-type stirring blade can be better driven to generate centrifugal force, so that the paint generates irregular vortices, breaks the symmetrical flow field and reduces the bottom residue in the paint tank.

Detailed Implementation

[0021] Reference Figure 1-5 A spraying device for waterproof coating construction includes a spraying bracket 1, an equipment box 2 fixedly installed on one side of the spraying bracket 1, a paint tank 5 fixedly installed on the other side of the spraying bracket 1, a top cover 9 fixedly installed on the top of the paint tank 5; a mixing shell 8 fixedly installed on the top of the top cover 9, and a drive chamber is opened inside the mixing shell 8.

[0022] In this embodiment, a pressure pump 3 is fixedly installed on the top of the spraying bracket 1, and a connecting pipe 6 is fixedly installed on the input end of the pressure pump 3, so that the paint in the paint tank 5 can be transported to the spraying equipment through the pressure pump 3.

[0023] In this embodiment, an electrically controlled valve 7 is fixedly installed at the bottom of the paint tank 5, and the other end of the connecting pipe 6 is connected to the electrically controlled valve 7 to facilitate control of the paint flow rate.

[0024] In this embodiment, four evenly distributed casters 4 are fixedly installed at the bottom of the spraying bracket 1 to facilitate the movement of the equipment.

[0025] In this embodiment, a drive bevel gear 11 is rotatably mounted on one inner wall of the drive chamber, and a forward bevel gear 12 and a reverse bevel gear 16 are rotatably mounted on the upper and lower inner walls of the drive chamber, respectively. The drive bevel gear 11 meshes with the forward bevel gear 12 and the reverse bevel gear 16. A motor slot is provided inside the stirring shell 8, and a servo motor 10 is fixedly mounted on one inner wall of the motor slot. The output shaft of the servo motor 10 is fixedly connected to the drive bevel gear 11, and the drive bevel gear 11 can be rotated by the servo motor 10.

[0026] In this embodiment, an eccentric shaft 13 is fixedly installed at the bottom of the forward bevel gear 12, and a dispersing shaft 17 is fixedly installed at the bottom of the reverse bevel gear 16. The dispersing shaft 17 extends out of the stirring shell 8 and rotates through the top cover 9. The eccentric shaft 13 rotates through the reverse bevel gear 16 and the dispersing shaft 17.

[0027] In this embodiment, a dispersion disk 18 is fixedly installed on the outer side of the dispersion shaft 17, which can shear and break up clumps or bubbles floating on the surface.

[0028] In this embodiment, the outer side of the eccentric shaft 13 is fixedly fitted with an anchor-type stirring blade 15 and two paddle-type stirring blades 14. The blades of the two paddle-type stirring blades 14 are inclined to facilitate the agitation of the coating.

[0029] Working principle: During the application of waterproof coating, the worker pours the coating into the coating tank 5 and then starts the equipment. The servo motor 10 starts, driving the active bevel gear 11 to rotate. The rotation of the active bevel gear 11 drives the forward bevel gear 12 and the reverse bevel gear 16 to rotate. The rotation of the forward bevel gear 12 drives the eccentric shaft 13 to rotate clockwise. The rotation of the eccentric shaft 13 drives the two paddle-type stirring blades 14 to rotate. The blades of the two paddle-type stirring blades 14 are inclined, and the rotation generates axial thrust, which flips the coating at the bottom upward. At the same time, the eccentric shaft 13 drives the anchor-type stirring blades 15 to rotate, scraping off the coating adhering to the inner wall of the coating tank 5 to prevent sedimentation. The coating material is clumped, and when the eccentric shaft 13 rotates, it can use centrifugal force to generate irregular vortices in the coating, breaking the symmetrical flow field and reducing the residue at the bottom of the coating tank 5. The rotation of the reverse bevel gear 16 drives the dispersion shaft 17 to rotate counterclockwise, which in turn drives the dispersion disk 18 to rotate, which can shear and break up the clumps or bubbles floating on the surface. The anchor-type stirring blade 15 and the paddle-type stirring blade 14 rotate in the forward direction to push the coating to form an overall circulation, while the counterclockwise rotating dispersion disk 18 generates strong shear force locally. The two form a composite flow field of convection and shear, which can not only make the coating uniformly mixed, but also efficiently break up clumps and disperse particles, thereby preventing the coating from separating.

[0030] The technological advancements of this invention compared to existing technologies are as follows: by utilizing the anchor-type stirring blade 15, the paddle-type stirring blade 14, and the dispersion disc 18, the three components work together to cover the upper, middle, lower, and edge areas of the paint tank 5, forming a three-dimensional stirring cycle. This completely solves the problems of multiple dead zones and difficulty in agitating sediment when using a single blade. Furthermore, the eccentric shaft 13 can better drive the anchor-type stirring blade 15 and the paddle-type stirring blade 14 to generate centrifugal force, causing the paint to produce irregular vortices, breaking the symmetrical flow field, and reducing the residue at the bottom of the paint tank 5.
