Description

Technical Field

[0001] This utility model relates to the field of coating sand milling technology, specifically to a vertical bucket-type coating sand mill. Background Technology

[0002] There are many types of grinding and dispersing equipment used in the coating industry. Among them, the most commonly used in coating production are vertical sand mills, three-roll mills, and basket mills. In the process of coating and paint production, it is necessary to grind large particles of raw materials into powder or small particles that meet the requirements.

[0003] The patent specification with announcement number CN210386068U discloses a filterable vertical sand mill, which relates to paint production equipment. It aims to solve the technical problem of a small amount of residual grinding material in the discharged material, leading to a decline in material quality. The key technical points include a frame and a material cylinder. The material cylinder has an inlet and an outlet. A support plate is provided on the inner wall of the inlet, and a guide port is provided on the support plate. A filter screen is provided on the inner wall of the guide port. When the material is discharged from the outlet, the small amount of grinding material carried in the material is filtered out by the filter screen, thereby ensuring the quality of the discharged material.

[0004] While the aforementioned technical solutions filter the ground materials, in actual operation, different types of materials require different grinding degrees, resulting in varying particle sizes after grinding. Furthermore, the filter screens in these solutions have constant pore sizes, which cannot meet user needs. Therefore, we propose a vertical bucket-type coating sand mill. Utility Model Content

[0005] This utility model provides a vertical bucket-type coating sand mill that solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0007] An embodiment of this utility model provides a vertical bucket-type coating sand mill, comprising:

[0008] Grinding machine body;

[0009] The bottom barrel is threaded onto the surface of the grinding machine body to support the grinding equipment;

[0010] The grinding barrel is fixedly connected to the upper surface of the bottom barrel to achieve the grinding and storage of materials;

[0011] The connecting pipe is fixedly connected to the discharge port of the grinding barrel to store the filter screen;

[0012] The discharge pipe is fixedly connected to the discharge end of the connecting pipe to guide the discharge of the ground material.

[0013] The replacement device is located on the outside of the sander body, allowing for the removal and replacement of the filter screen.

[0014] Furthermore, the replacement device includes a storage slot, which is opened on the lower surface of the connecting pipe, and a filter plate is provided inside the storage slot. A movable plate is provided on the lower surface of the filter plate, and a threaded rod is threadedly installed on one side of the movable plate. The bottom end of the threaded rod is fixedly connected to the output end of a drive motor.

[0015] Through the above technical solution, the drive motor is used to rotate the threaded rod, which in turn drives the movable plate that is threadedly mounted to it to adjust its height. This allows the filter plate mounted on the movable plate to be pulled out of the storage slot or placed into the storage slot, thus enabling the disassembly and assembly of the filter. Ultimately, it allows for the quick replacement of filter plates that are suitable for different materials.

[0016] The filter plate has uniformly distributed filter holes on its surface, and the filter plate and the connecting pipe are movably installed.

[0017] The above technical solution uses the set filter holes to filter the ground material. At the same time, replacing the filter plate with filter holes of different diameters can adapt to the filtration of different material particles.

[0018] The upper end of the threaded rod is rotatably mounted to the connecting pipe, and the lower end of the threaded rod is rotatably mounted to a support plate.

[0019] The above technical solution utilizes a threaded rod to move the filter plate in and out of the storage tank, making it easy to replace.

[0020] A sliding rod is slidably installed on the other side of the movable plate. The upper end of the sliding rod is fixedly installed to the connecting pipe, and the lower end of the sliding rod is fixedly installed to the support plate.

[0021] The above technical solution utilizes a sliding rod to increase the stability of the moving plate when adjusting its height.

[0022] The drive motor is fixedly installed on the lower surface of the support plate, and the outer surface of the bottom barrel is fixedly installed with evenly distributed support frames.

[0023] The above technical solution utilizes a drive motor to rotate a threaded rod, which in turn allows the moving plate to adjust its height.

[0024] The upper surface of the movable plate is fixedly connected with evenly distributed positioning posts, and the bottom end of the filter plate is provided with evenly distributed positioning holes.

[0025] The above technical solution utilizes the positioning pins that enter the positioning holes to provide support for the filter plate, making it convenient to place the filter plate on the moving plate for height adjustment.

[0026] The positioning post is disposed in the positioning hole, and the positioning post is movably installed with the filter plate.

[0027] The above technical solution utilizes the positioning columns to movably install the filter plate, thus providing support for the filter plate.

[0028] The above-described solution of this utility model has at least the following beneficial effects:

[0029] This utility model uses a drive motor to rotate a threaded rod, which in turn drives a movable plate that is threadedly mounted on the movable plate to adjust its height. This allows the filter plate mounted on the movable plate to be pulled out of or placed into the storage slot, thus enabling the disassembly and assembly of the filter. Ultimately, it allows for the quick replacement of filter plates that are suitable for different materials.

[0030] This invention features a positioning pin that enters the positioning hole to support the filter plate during replacement. This allows the filter plate to be supported on the moving plate, facilitating its vertical movement without causing it to be cut at an angle. This makes it easier to align with the storage slot for insertion. Attached Figure Description

[0038] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0039] like Figures 1 to 2 As shown, an embodiment of this utility model provides a vertical bucket-type coating sand mill, comprising: a sand mill body 1; a bottom bucket 2, threadedly installed on the surface of the sand mill body 1 to support the grinding equipment; a grinding bucket 4, fixedly connected to the upper surface of the bottom bucket 2 to collect and grind materials; a connecting pipe 5, fixedly connected to the discharge port of the grinding bucket 4 to collect the filter screen; a discharge pipe 6, fixedly connected to the discharge end of the connecting pipe 5 to guide the discharge of the ground materials; and a replacement device 7, located on the outside of the sand mill body 1, to disassemble and replace the filter screen.

[0040] like Figures 2 to 4 As shown, the replacement device 7 includes a receiving groove 701, which is located on the lower surface of the connecting pipe 5. A filter plate 702 is installed inside the receiving groove 701. A movable plate 704 is located on the lower surface of the filter plate 702. A threaded rod 705 is threaded onto one side of the movable plate 704, and the bottom end of the threaded rod 705 is fixedly connected to the output end of a drive motor 706. The drive motor 706 drives the threaded rod 705 to rotate, causing the threaded rod 705 to adjust the height of the threaded movable plate 704. This allows the filter plate 702 mounted on the movable plate 704 to be pulled out of or placed back into the receiving groove 701, enabling the removal and installation of the filter. Ultimately, this allows for the rapid replacement of filter plates 702 suitable for different materials. The surface of the filter plate 702 has evenly distributed filter holes 703, and the filter plate 702 is movably installed with the connecting pipe 5. The ground material is filtered using the filter holes 703. Different filter plates 702 with varying diameter filter holes 703 can be used to filter different particle sizes. The upper end of the threaded rod 705 is rotatably mounted to the connecting pipe 5, and the lower end of the threaded rod 705 is rotatably mounted to a support plate 8.

[0041] In this embodiment of the utility model, when it is necessary to replace the filter plate 702 with a filter hole 703 of different diameter, the first step is to determine the required diameter of the filter plate 702 based on the material. After selecting the filter, the positioning pin 9 is inserted into the positioning hole 10 of the filter plate 702 to support it. Then, the drive motor 706 is started, which drives the threaded rod 705 to rotate. The threaded rod 705 drives the moving plate 704, which is threadedly installed with it, to adjust its height. This allows the filter plate 702 installed on the moving plate 704 to be pulled out of the storage groove 701 or placed into the storage groove 701, thus enabling the disassembly and assembly of the filter. Ultimately, this allows for the quick replacement of the filter plate 702 to accommodate different materials.

[0042] like Figures 2 to 5 As shown, a sliding rod 11 is slidably installed on the other side of the movable plate 704. The upper end of the sliding rod 11 is fixedly installed with the connecting pipe 5, and the lower end of the sliding rod 11 is fixedly installed with the support plate 8. The drive motor 706 is fixedly installed on the lower surface of the support plate 8, and the outer surface of the bottom barrel 2 is fixedly installed with evenly distributed support frames 3. Evenly distributed positioning posts 9 are fixedly connected to the upper surface of the movable plate 704, and evenly distributed positioning holes 10 are opened at the bottom end of the filter plate 702. By setting the positioning posts 9 into the positioning holes 10, the positioning posts 9 can provide support for the filter plate 702 when it is replaced, so that the filter plate 702 can be supported on the movable plate 704. Finally, it is convenient for the movable plate 704 to move the filter plate 702 up and down without cutting the filter plate 702 at an angle, so as to facilitate alignment with the storage slot 701. The positioning posts 9 are set in the positioning holes 10, and the positioning posts 9 and the filter plate 702 are movably installed.

[0043] In this embodiment of the utility model, by setting a positioning hole 10 and positioning pin 9 into the positioning hole 10, the positioning pin 9 can provide support for the filter plate 702 when it is replaced. This allows the filter plate 702 to be supported on the moving plate 704, which makes it easier for the moving plate 704 to move the filter plate 702 up and down without cutting it at an angle, thus facilitating alignment with the storage slot 701.

[0044] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
