Description

Technical Field

[0001] The utility model relates to the technical field of paint production, in particular to an auxiliary stirring device for wall paint production. Background Art

[0002] Wall paint, as an essential material in modern building decoration, not only provides rich colors and textures for indoor spaces but also plays multiple roles such as protecting the wall, preventing moisture and mildew, and beautifying the environment. Its excellent covering power, adhesion, and weather resistance make wall paint the preferred material for home decoration and public building decoration.

[0003] In the production process of wall paint, stirring is a crucial link. Effective stirring can ensure the uniform mixing of each component of the paint, improving the stability and construction performance of the paint. Currently, common stirring devices on the market mostly use electric motors and are combined with a simple stirring frame structure to achieve the basic stirring function of the paint. This design has a simple structure and is convenient to operate.

[0004] However, in actual applications of existing stirring devices, the paint is prone to gradually solidify on the inner wall of the stirring barrel. This is mainly because the stirrer usually only performs efficient mixing in the central area of the stirring barrel. Due to the weak centrifugal force on the paint near the barrel wall and the gap between the stirrer and the barrel wall, the paint gradually solidifies after long-term contact with air. For small stirring barrels, workers can manually scrape it off. For large stirring barrels, due to their large volume and increased weight, it is difficult for operators to use tools to comprehensively and thoroughly scrape off the paint residue on the barrel wall. The paint solidified on the barrel wall not only increases the cleaning difficulty but may also become harder during subsequent collection, which not only affects the reuse of the paint but also brings inconvenience to the painting or spraying operation of the paint, reducing the overall production efficiency and product quality. Summary of the Utility Model

[0005] In order to overcome the shortcoming that the paint is prone to hanging on the wall, the utility model provides an auxiliary stirring device for wall paint production with a wall scraping function.

[0006] An auxiliary stirring device for wall paint production includes a support assembly, a stirring barrel, a stirring rod, a support rod, a turntable, a scraping plate, and a transmission assembly. A motor is installed on the support assembly, the stirring barrel is connected to the support assembly, the output shaft of the motor faces downward and is connected to the stirring rod, the stirring rod extends into the stirring barrel, a support rod is connected inside the stirring barrel, the stirring rod is rotatably connected to the support rod, a turntable is rotatably connected to the stirring rod, scraping plates are connected around the turntable, the scraping plates are in contact with the inner wall of the stirring barrel, and a transmission assembly is arranged inside the turntable for transmitting the power of the stirring rod to the turntable.

[0007] Further explanation: The transmission assembly includes a ring gear, planet gears, and a gear. The ring gear is connected to the bottom of the turntable. A gear is connected to the stirring rod, and planet gears are rotatably connected to the support rods. The planet gears are meshed with both the ring gear and the gear. When the stirring rod rotates, the planet gears transmit the power of the gear to the ring gear to provide the power required for the rotation of the turntable.

[0008] Further explanation: It also includes a slide rail. The bottom of the ring gear is connected to the slide rail, and the slide rail is slidably connected to the top of the support rod and is in clearance fit with the support rod.

[0009] Further explanation: It also includes rubber sheets. The scraping plate is chamfered, with inclined surfaces on both sides, and smooth rubber sheets are connected to the surface of the scraping plate.

[0010] Further explanation: It also includes a baffle. A baffle is commonly connected to the outer circle of the top of the scraping plate to prevent the paint from splashing.

[0011] Further explanation: It also includes a protective cover. The protective cover is connected to the support rod, and the top of the protective cover is slidably connected to the bottom of the turntable. A cavity is formed between the protective cover and the turntable to wrap the transmission assembly.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. During the rotation of the scraping plate, it can not only effectively scrape off the paint residue on the inner wall of the stirring barrel, prevent it from solidifying and caking, reduce the adhesion and residue of the paint on the scraping plate, facilitate the smooth discharge of the subsequent paint, and improve the utilization rate of the paint.

[0014] 2. Through the opposite design of the rotation directions of the stirring rod and the scraping plate, the common problems of eddy currents and dead corners during the stirring process are effectively avoided, ensuring that the paint and additives in the stirring barrel can be more evenly and fully mixed, significantly improving the stirring efficiency and effect.

[0020] The present utility model will now be described more fully hereinafter with reference to the accompanying drawings, in which the currently preferred embodiments of the present utility model are shown. However, the present utility model can be implemented in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness and fully convey the scope of the present utility model to those skilled in the art.

[0021] Example: An auxiliary stirring device for the production of wall coatings, as Figures 1-4 shown, includes a support assembly 1, a stirring barrel 2, a stirring rod 3, a support rod 4, a turntable 5, a scraper 6 and a transmission assembly. A motor is installed on the support assembly 1, the stirring barrel 2 is connected to the support assembly 1, the bottom of the stirring barrel 2 is a curved surface, the outer ring is concave towards the middle, and a discharge cover plate is arranged in the middle. The output shaft of the motor faces downwards and is connected to the stirring rod 3. The stirring rod 3 extends into the stirring barrel 2. A support rod 4 is connected inside the stirring barrel 2. The stirring rod 3 is rotatably connected to the support rod 4. A turntable 5 is rotatably connected to the stirring rod 3. Scrapers 6 are connected around the turntable 5. The scrapers 6 are in contact with the inner wall of the stirring barrel 2. A transmission assembly is arranged inside the turntable 5 for transmitting the power of the stirring rod 3 to the turntable 5.

[0022] As Figure 3 and Figure 4 shown, the transmission assembly includes a gear ring 7, a planet gear 8 and a gear 9. The gear ring 7 is connected to the bottom of the turntable 5. A gear 9 is connected to the stirring rod 3. A planet gear 8 is rotatably connected to the support rod 4. The planet gear 8 meshes with both the gear ring 7 and the gear 9. When the stirring rod 3 rotates, the planet gear 8 transmits the power of the gear 9 to the gear ring 7 to provide the power required for the rotation of the turntable 5.

[0023] The staff pour the paint and additives to be stirred into the mixing barrel 2, and then start the motor. The motor drives the stirring rod 3 to rotate, stirring the paint in the mixing barrel 2 and evenly mixing the additives. While the stirring rod 3 rotates, it drives the gear 9 to rotate. Since the gear 9 meshes with the planet gear 8, the planet gear 8 is driven to rotate. And the planet gear 8 meshes with the gear ring 7, so the gear ring 7 also rotates accordingly. The gear ring 7 is externally tangent to the planet gear 8, so the rotation directions of the gear ring 7 and the planet gear 8 are opposite. The planet gear 8 is internally tangent to the gear 9, so the rotation directions of the planet gear 8 and the gear 9 are the same. Therefore, the rotation directions of the gear 9 and the gear ring 7 are opposite. The gear ring 7 drives the scraper 6 on the turntable 5 to rotate, so the rotation directions of the stirring rod 3 and the scraper 6 are opposite, which can effectively avoid the vortex or dead angle generated during the stirring process, make the material more evenly mixed in the mixing barrel 2, and improve the stirring efficiency and effect. During the rotation of the scraper 6, the paint on the mixing barrel 2 is continuously scraped off, reducing the situation of paint adhesion. After the stirring is completed, the discharge cover plate at the bottom of the mixing barrel 2 is opened to complete the discharging, and then the motor is turned off.

[0024] As Figure 3 and Figure 4 shown, it also includes a slide rail 10. The bottom of the gear ring 7 is connected with the slide rail 10. The slide rail 10 is slidably connected to the top of the support rod 4 and has a clearance fit with the support rod 4.

[0025] The slide rail 10 can support the gear ring 7, thus reducing the friction between the gear ring 7 and the support rod 4. Moreover, the slide rail 10 and the support rod 4 have a clearance fit, and the frictional resistance to the gear ring 7 is small, thereby optimizing the power transmission efficiency of the transmission component.

[0026] As Figure 2 shown, it also includes a rubber sheet 11. The scraper 6 is chamfered, with both sides being inclined planes, and a smooth rubber sheet 11 is connected to the surface of the scraper 6.

[0027] The inclined planes on both sides of the scraper 6 can push the paint towards the middle while scraping off the paint, reducing the situation of paint adhesion on the straight surface. Cooperating with the smooth rubber sheet 11, it can further reduce the situation of paint residue on the scraper 6, which is beneficial to discharging.

[0028] As Figure 1 shown, it also includes a baffle 12. The outer circle at the top of the scraper 6 is commonly connected with the baffle 12, which is used to block the splashing of the paint.

[0029] During the stirring process, the paint splashes out when the top of the scraper 6 collides with the paint, and the splashing paint is blocked by the baffle 12, thereby reducing the pollution of the paint to the external environment and reducing the labor intensity of the staff for cleaning work.

[0030] As Figure 1As shown, it further includes a protective cover 13. The protective cover 13 is connected to the support rod 4. The top of the protective cover 13 is slidably connected to the bottom of the turntable 5. The protective cover 13 and the turntable 5 form a cavity for wrapping the transmission component.

[0031] The protective cover 13 can prevent the splashed paint from sticking to the transmission component, which may affect the transmission effect of the transmission component or even damage the transmission component after solidification, thus playing a role in protecting the gear ring 7, the planet gear 8 and the gear 9.

[0032] The motor drives the stirring rod 3 to rotate. The stirring rod 3 not only directly stirs the paint, but also indirectly drives the turntable 5 and the scraping plate 6 to rotate through the gear 9 connected thereto meshing with the planet gear 8. The planet gear 8 meshes with the gear ring 7 at the same time. Due to the characteristics that the planet gear 8 is internally tangent to the gear 9 and externally tangent to the gear ring 7, the opposite rotation directions of the stirring rod 3 and the scraping plate 6 are realized, effectively avoiding the stirring vortex and improving the mixing uniformity. The inclined surface design of the scraping plate 6 and the rubber sheet 11 thereon not only reduce the paint residue, but also guide the paint to flow towards the center of the mixing bucket, while the baffle 12 effectively prevents the paint from splashing and reduces environmental pollution. The slide rail 10 connected to the bottom of the gear ring 7 is in clearance fit with the support rod 4, effectively reducing the friction of the gear ring 7 during rotation, thereby optimizing the power transmission efficiency of the transmission component. In addition, the protective cover 13 covers the transmission component to prevent the paint from invading and protects the key components from damage. The whole device realizes the efficient stirring of the paint and the cleaning of the barrel wall through the coordinated work of each component, and finally completes the discharging through the bottom discharging cover plate, ensuring the smooth progress of the paint production.
