Description

Technical Field

[0001] This utility model relates to the field of coating processing, and in particular to a simple water-based coating grinding machine. Background Technology

[0002] Water-based coatings use water as a solvent or dispersion medium and offer numerous advantages, such as being environmentally friendly and non-toxic, significantly reducing environmental pollution and health hazards caused by the volatilization of organic solvents; easy to clean, as painting tools can be cleaned with water, reducing the consumption of cleaning solvents; and fast drying speed, improving construction efficiency. During the production and processing of water-based coatings, grinding machines are typically used for grinding.

[0003] In related technologies, the production of water-based coatings mainly relies on grinding mills to refine and uniformly disperse solid particles such as pigments and fillers in the coating, ensuring that the particle size meets the process requirements. This enhances the coloring power, hiding power, and stability of the coating. Traditional water-based coating grinding mills, such as pin mills, mostly adopt a horizontal structure. Their working principle is that a high-speed rotating rotor drives the grinding media to move in the grinding chamber, impacting, shearing, and grinding the pigments, fillers, and other particles in the coating, continuously reducing their particle size to achieve the required fineness.

[0004] However, traditional water-based coating grinding mills are usually complex in structure and large in size, which may not be convenient for small-scale water-based coating production or experimental needs.

[0005] Therefore, it is necessary to provide a simple water-based coating grinding machine to solve the above problems. Utility Model Content

[0006] To address the technical problem that conventional water-based coating grinding machines are typically complex in structure and large in size, which may be inconvenient for small-scale water-based coating production or experimental needs, this utility model provides a simplified water-based coating grinding machine.

[0007] This utility model provides a simple water-based coating grinding machine, comprising: a grinding barrel, a protective cover on the upper surface of the grinding barrel, a funnel-shaped grinding cylinder fixedly connected to the inner wall of the grinding barrel, a conical grinding roller inside the funnel-shaped grinding cylinder, a drive mechanism and a stirring paddle, wherein the drive mechanism is mounted on the protective cover and penetrates the protective cover, the outer wall of the drive mechanism is fixedly connected to the inner wall of the conical grinding roller, the stirring paddle is fixedly mounted on the lower end face of the drive mechanism, a support frame and support columns, wherein the support frame is located at the bottom of the grinding barrel, and two support columns are provided, the two support columns are symmetrically fixedly mounted on the outer wall of the grinding barrel, and the outer walls of the two support columns are rotatably connected to the top of both sides of the support frame.

[0008] Preferably, the protective cover includes a circular cover plate located on the upper surface of the grinding barrel, and a feeding pipe is fixedly connected to the circular cover plate.

[0009] Preferably, the support frame includes a rectangular base plate located below the grinding barrel. Supporting uprights are symmetrically fixedly connected to the upper surface of the rectangular base plate. The grinding barrel is located between the symmetrically arranged supporting uprights. An installation groove is formed on the upper surface of the supporting uprights, and the supporting column is located inside the installation groove.

[0010] Preferably, the upper surface of the circular cover plate is symmetrically fixedly connected with ear plates, and a handle is provided above the circular cover plate, which is hinged to the symmetrically arranged ear plates.

[0011] Preferably, the outer wall of the connection between the grinding barrel and the circular cover plate is provided with a plurality of snap-fit ​​components evenly arranged around the circumference. The snap-fit ​​components include symmetrically arranged mounting plates and symmetrically arranged limiting plates. One side of the mounting plate is fixedly connected to the outer wall of the grinding barrel, and one side of the limiting plate is fixedly connected to the outer wall of the circular cover plate. The symmetrically arranged mounting plates are hinged with eye bolts, and the end of the eye bolt away from the mounting plate is snapped with the symmetrically arranged limiting plates.

[0012] Preferably, the driving mechanism includes a motor, the lower surface of which is fixedly connected to the upper surface of the circular cover plate, the output end of which is fixedly connected to a shaft through the circular cover plate, the outer wall of which is fixedly connected to the inner wall of the conical grinding roller, and the lower end face of which is fixedly connected to the upper surface of the stirring paddle.

[0013] Compared with related technologies, the simple water-based coating grinding machine provided by this utility model has the following beneficial effects:

[0014] 1. This simple water-based coating grinding machine is suitable for small-scale water-based coating production or experimental use. The grinding drum serves as the core carrier, and the protective cover protects the interior. A funnel-shaped grinding cylinder and a conical grinding roller form a close grinding gap. When the drive mechanism is activated, the conical grinding roller rotates, and the conical grinding roller, in conjunction with the funnel-shaped grinding cylinder, extrudes and shears the water-based coating material to refine it. Simultaneously, the drive mechanism rotates the conical grinding roller, which in turn rotates the stirring paddle at the lower end of the drive mechanism to stir the ground material. Symmetrically arranged support columns and frames on both sides of the grinding drum support the drum and allow for easy control of the drum's movement, improving the grinding and stirring effect on the water-based coating inside. This water-based coating grinding machine has a simple structure, and the grinding drum can be set to the size of a water bucket. Compared to the bulky body of traditional horizontal sand mills, this application is convenient for small-scale water-based coating production or experimental use.

[0015] 2. This simple water-based paint grinder features a circular cover that protects the inside of the grinding barrel. Personnel can add materials to be ground through the feeding pipe. A rectangular base plate restricts the installation position of the symmetrically arranged support plates, and mounting grooves restrict the installation position of the support columns at the top of the support plates. The symmetrically arranged support plates and columns work together to support the grinding barrel. Symmetrically arranged ear plates restrict the installation position of the handles on the circular cover. Personnel can control the opening and closing of the circular cover or move the grinding barrel by hand using the handles.

[0016] 3. This simple water-based paint grinding machine uses multiple locking devices to limit the movement between the grinding barrel and the circular cover plate. Symmetrically arranged mounting plates restrict the installation and movement of the lifting eye bolts. When the operator moves the end of the lifting eye bolt furthest from the mounting plate above the symmetrically arranged limiting plates and tightens the lifting eye part of the bolt, the lifting eye bolt engages with the symmetrically arranged limiting plates, thus restricting the closed position between the circular cover plate and the grinding barrel. Starting the motor drives the shaft to rotate, which in turn drives the conical grinding roller and the agitator. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please refer to the following: Figures 1 to 4 A simple water-based coating grinding machine includes: a grinding barrel 1, a protective cover 2 on the upper surface of the grinding barrel 1, a funnel-shaped grinding cylinder 3 fixedly connected to the inner wall of the grinding barrel 1, a conical grinding roller 4 inside the funnel-shaped grinding cylinder 3, a drive mechanism 5 and a stirring paddle 6, wherein the drive mechanism 5 is mounted on the protective cover 2 and passes through the protective cover 2, the outer wall of the drive mechanism 5 is fixedly connected to the inner wall of the conical grinding roller 4, the stirring paddle 6 is fixedly mounted on the lower end face of the drive mechanism 5, a support frame 7 and support columns 8, wherein the support frame 7 is located at the bottom of the grinding barrel 1, and there are two support columns 8, which are symmetrically fixedly mounted on the outer wall of the grinding barrel 1, and the outer walls of the two support columns 8 are rotatably connected to the top of both sides of the support frame 7.

[0024] In the specific implementation process, the grinding barrel 1 in this simple water-based coating grinding machine is the core carrier. The interior of the grinding barrel 1 is protected by closing the protective cover 2. A closely fitting grinding gap is formed between the funnel-shaped grinding cylinder 3 fixed to the inner wall of the grinding barrel 1 and the conical grinding roller 4 inside. A drive mechanism 5 is installed on the protective cover 2, and the outer wall of the drive mechanism 5 is fixedly connected to the inner wall of the conical grinding roller 4. When the drive mechanism 5 drives the conical grinding roller 4 to rotate, the material for processing water-based coatings can automatically flow into the grinding gap under the guidance of the funnel-shaped structure of the funnel-shaped grinding cylinder 3. Refinement is achieved through the squeezing and shearing between the conical grinding roller 4 and the funnel-shaped grinding cylinder 3. Furthermore, the drive mechanism 5 drives the conical grinding roller 4... While rotating, it can drive the stirring paddle 6 set on the lower end face of the drive mechanism 5 to rotate. The rotation of the stirring paddle 6 can stir the ground material to prevent local accumulation of material. Furthermore, the symmetrically arranged support columns 8 on both sides of the grinding barrel 1 cooperate with the support frame 7 to support the grinding barrel 1. The symmetrically arranged support columns 8 and support frame 7 are rotatably connected, which makes it easy for personnel to control the shaking of the grinding barrel 1 and improve the grinding and stirring effect of the water-based coating inside the grinding barrel 1. This water-based coating grinding machine has a simple structure, and the grinding barrel 1 can be set to the size of a water bucket. Compared with the bulky body of the traditional horizontal sand mill, this application is convenient for small-scale water-based coating production or experimental use.

[0025] Specifically, a discharge valve is installed on one side of the bottom of the grinding barrel 1 to facilitate the discharge of the ground material. The inner wall of the funnel-shaped grinding cylinder 3 and the outer wall of the conical grinding roller 4 are both rough surfaces, and the gap between the inner wall of the funnel-shaped grinding cylinder 3 and the outer wall of the conical grinding roller 4 gradually narrows from top to bottom. When the drive mechanism 5 drives the conical grinding roller 4 to rotate, the rough surface increases the friction, and the gradually narrowing gap causes the material to be subjected to increasing compression and shearing forces, thus gradually refining the particles.

[0026] See Figure 1 , Figure 2 and Figure 3 As shown, the protective cover 2 includes a circular cover plate 201, which is located on the upper surface of the grinding barrel 1, and a feeding pipe 202 is fixedly connected to the circular cover plate 201.

[0027] In the specific implementation process, the inside of the grinding barrel 1 can be protected by closing the circular cover plate 201. The operator can add the material to be ground into the grinding barrel 1 through the feeding pipe 202. It should be noted that a sealing ring can be installed between the contact surface between the circular cover plate 201 and the grinding barrel 1 as needed.

[0028] See Figure 1 , Figure 3 and Figure 4As shown, the support frame 7 includes a rectangular base plate 701, which is located below the grinding barrel 1. The upper surface of the rectangular base plate 701 is symmetrically fixed with support plates 702. The grinding barrel 1 is located between the symmetrically arranged support plates 702. The upper surface of the support plates 702 is provided with an installation groove 703, and the support column 8 is located inside the installation groove 703.

[0029] In the specific implementation process, the rectangular base plate 701 can restrict the installation position of the symmetrically arranged support plates 702, and the installation groove 703 can restrict the installation position of the support column 8 at the top of the support plate 702. Thus, the symmetrically arranged support plates 702 and the symmetrically arranged support columns 8 can cooperate to support the grinding barrel 1. The support column 8 is installed directly inside the installation groove 703, which makes it easy for personnel to disassemble the grinding barrel 1 from the support frame 7 and use or carry the grinding barrel 1 separately.

[0030] See Figure 1 , Figure 2 and Figure 3 As shown, ear plates 9 are symmetrically fixedly connected to the upper surface of the circular cover plate 201, and handles 10 are hinged to the symmetrically arranged ear plates 9 on the top of the circular cover plate 201.

[0031] In the specific implementation process, the symmetrically arranged ear plates 9 can limit the installation position of the handle 10 on the circular cover plate 201. The operator can easily control the opening and closing of the circular cover plate 201 or carry and move the grinding barrel 1 by hand through the handle 10.

[0032] See Figure 1 , Figure 2 and Figure 3 As shown, a plurality of snap-fit ​​parts 11 are evenly arranged on the outer wall of the connection between the grinding barrel 1 and the circular cover plate 201. Each snap-fit ​​part 11 includes a symmetrically arranged mounting plate 1101 and a symmetrically arranged limiting plate 1102. One side of the mounting plate 1101 is fixedly connected to the outer wall of the grinding barrel 1, and one side of the limiting plate 1102 is fixedly connected to the outer wall of the circular cover plate 201. A lifting eye bolt 1103 is hinged between the symmetrically arranged mounting plates 1101. The end of the lifting eye bolt 1103 away from the mounting plate 1101 is snapped with the symmetrically arranged limiting plate 1102.

[0033] In the specific implementation process, multiple snap-fit ​​parts 11 can limit the position between the grinding barrel 1 and the circular cover plate 201 to prevent the circular cover plate 201 from opening and closing arbitrarily. The symmetrically arranged mounting plates 1101 can limit the installation and movement position of the lifting eye bolt 1103. When the operator moves the end of the lifting eye bolt 1103 away from the mounting plate 1101 to the symmetrically arranged limiting plate 1102, the lifting eye part of the lifting eye bolt 1103 can be tightened so that the lifting eye bolt 1103 can be snapped with the symmetrically arranged limiting plate 1102, thereby limiting the closed position between the circular cover plate 201 and the grinding barrel 1.

[0034] See Figure 1 , Figure 2 and Figure 3 As shown, the drive mechanism 5 includes a motor 501. The lower surface of the motor 501 is fixedly connected to the upper surface of the circular cover plate 201. The output end of the motor 501 is fixedly connected to a shaft 502 through the circular cover plate 201. The outer wall of the shaft 502 is fixedly connected to the inner wall of the conical grinding roller 4. The lower end face of the shaft 502 is fixedly connected to the upper surface of the stirring paddle 6.

[0035] In the specific implementation process, the starting motor 501 can drive the shaft 502 to rotate. The rotation of the shaft 502 can drive the conical grinding roller 4 and the stirring paddle 6 to rotate. It should be noted that the motor 501 is a device with relatively mature existing technology. The specific model can be selected according to actual needs. At the same time, the motor 501 can be powered by the built-in power supply or by the mains power. The specific power supply method is selected according to the situation.

[0036] The working principle of the simple water-based coating grinding machine provided by this utility model is as follows:

[0037] When the simple water-based paint grinder is in operation, the circular cover plate 201 is closed, and water-based paint material is added to the grinding barrel 1 through the feeding pipe 202. The circular cover plate 201 and the grinding barrel 1 are limited by the snap-fit ​​component 11. The motor 501 is started to drive the shaft 502 to rotate, and the shaft 502 drives the conical grinding roller 4 to rotate. At the same time, it drives the stirring paddle 6 to rotate. Under the guidance of the funnel-shaped grinding cylinder 3, the material automatically flows into the grinding gap between the funnel-shaped grinding cylinder 3 and the conical grinding roller 4. Through the rough surface of the inner wall of the funnel-shaped grinding cylinder 3 and the outer wall of the conical grinding roller 4, the squeezing and shearing force on the material is continuously increased, so as to achieve particle refinement. The stirring paddle 6 rotates to stir the ground material and prevent local accumulation. The support column 8 is rotatably connected to the support frame 7, so that the personnel can shake the grinding barrel 1 during the grinding process to improve the grinding and stirring effect.
