Description

Technical Field

[0001] This utility model relates to the technical field of paint grinding machines, specifically a paint grinding machine with a function of filtering impurities. Background Technology

[0002] In the paint production and processing process, the grinding process is crucial. Vertical grinding mills are commonly used grinding equipment. However, paint raw materials often contain some large particles of impurities. If these large particles of impurities directly enter the grinding mill, they will not only affect the grinding effect and lead to a decrease in the quality of the ground paint, but may also cause wear on the grinding components inside the grinding mill, shorten the service life of the equipment, and increase equipment maintenance and production costs. Therefore, it is essential to filter the paint to remove impurities before it enters the grinding mill.

[0003] Most existing paint grinding equipment lacks an effective impurity filtration device, or the filtration device has many inconveniences. For example, the filter device may be difficult to disassemble and clean, causing impurities to accumulate inside the filter device, affecting the filtration effect. Moreover, the cleaning process is cumbersome, consuming manpower and time. Furthermore, it is troublesome to replace the filter screen as needed, requiring the removal of the corresponding equipment. Therefore, in order to solve the above problems, we propose a paint grinding machine with impurity filtration function to solve the above problems. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1: Please refer to Figures 1-4 A paint grinding mill with impurity filtration function includes a vertical grinding mill body 1. A filter box 4 is installed above the feed inlet of the vertical grinding mill body 1. A through hole is opened on the right side of the filter box 4, which extends into the interior of the filter box 4. A screen frame 11 is inserted into the filter box 4 through the through hole. A screen mesh 12 is installed at the bottom of the screen frame 11 for filtering the incoming paint and removing impurities. A pull plate 9 is welded to the side of the screen frame 11 located in the through hole. A clip is opened on the top surface of the pull plate 9. A cavity is provided on the right side of the filter box 4 and above the through hole. A movable plate 14 is slidably connected in the cavity. Multiple second springs 15 are evenly installed on the top surface of the movable plate 14 and the side of the top inner wall of the cavity of the filter box 4 that are close to each other. A locking block 13 is fixedly installed on the bottom surface of the movable plate 14. The locking block 13 penetrates and extends into the through hole of the filter box 4, and the locking block 13 can be locked into the locking groove on the top of the pull plate 9, thereby fixing the screen frame 11 in the filter box 4.

[0021] A feed hopper 5 is fixedly installed on the top of the filter box 4. Support frames 7 are welded to both sides of the top of the feed hopper 5. A vibration motor 6 is installed on the top surface of the support frame 7. When the paint enters the filter box 4 from the feed hopper 5, the vibration motor 6 is started. The vibration motor 6 drives the feed hopper 5 and the filter box 4 to vibrate, so that the paint is better dispersed and filtered on the screen 12, improving the filtration efficiency. A handle 10 is installed on the side of the pull plate 9 away from the screen frame 11. When it is necessary to clean the impurities on the screen 12, or to replace the corresponding screen 12, the operator can pull the screen frame 11 out of the filter box 4 through the handle 10, which is convenient and quick.

[0022] A mounting strip 16 is fixedly installed on the inner wall of the filter box 4 at the through hole on the right side. The left side, front side and back side of the screen frame 11 are provided with mounting slots that match the mounting strip 16. When the screen frame 11 is inserted into the filter box 4, the mounting strip 16 is inserted into the mounting slot, which further enhances the stability of the screen frame 11 installation. A receiving hopper 17 is installed at the lower part of the filter box 4. The receiving hopper 17 extends into the receiving port of the vertical grinder body 1. The filtered coating enters the vertical grinder body 1 for grinding through the receiving hopper 17. An mounting plate 3 is welded to the lower outer ring of the receiving hopper 17. Multiple first springs 2 are evenly installed on the top surface of the vertical grinder body 1 at the receiving port. The top of the multiple first springs 2 is connected to the bottom surface of the mounting plate 3. When the vibrating motor 6 drives the filter box 4 to vibrate, the first springs 2 can play a buffering role to reduce the impact of vibration on the vertical grinder body 1. At the same time, it can also make the receiving hopper 17 vibrate slightly with the filter box 4 to ensure that the coating enters the vertical grinder body 1 smoothly.

[0023] Example 2: Please refer to Figures 1-4 The structure of the paint grinding machine with impurity filtering function in this embodiment is basically the same as that in Embodiment 1. The difference lies in the inclined setting of the locking block 13 and the pull plate 9. The lower right side of the locking block 13 is inclined, and the upper left side of the pull plate 9 is inclined. When the screen frame 11 is inserted into the filter box 4, the inclined surface of the pull plate 9 will contact the inclined surface of the locking block 13. As the screen frame 11 continues to be inserted, the pull plate 9 will push the locking block 13 to move upward and compress the second spring 15. When the screen frame 11 is fully inserted, the locking block 13 moves downward under the action of the second spring 15 and is locked into the slot at the top of the pull plate 9 to achieve automatic locking. This inclined setting makes the installation of the screen frame 11 more convenient, without the need to manually operate the push plate 8 to move the locking block 13, thus improving the installation efficiency.

[0024] Meanwhile, a push plate 8 is installed in the middle of the right side of the moving plate 14. A through hole is opened on the right side of the filter box 4, extending through and into the cavity opened in the filter box 4. The push plate 8 moves within the through hole. When the screen frame 11 needs to be disassembled, the operator only needs to push the push plate 8 upward. The push plate 8 drives the moving plate 14 to move upward, compressing the second spring 15, causing the locking block 13 to disengage from the slot of the pull plate 9. Then, the screen frame 11 can be pulled out through the handle 10. This design makes the disassembly of the screen frame 11 more convenient and facilitates the cleaning of impurities on the screen 12.

[0025] Example 3: Please refer to Figures 1-4Based on Embodiment 2, this embodiment further optimizes the connection structure between the filter box 4 and the screen frame 11. In addition to fixing the mounting strip 16 to the inner wall of the through hole on the right side of the filter box 4, and opening mounting grooves matching the mounting strip 16 on the left side, the front side, and the back side of the screen frame 11, sealing strips (not shown in the figure) can also be installed on the front and back sides of the screen frame 11. When the screen frame 11 is inserted into the filter box 4, the sealing strip is in close contact with the inner wall of the filter box 4, preventing the coating from leaking from the gap between the screen frame 11 and the filter box 4, thereby improving the filtration effect and the sealing of the equipment.

[0026] In addition, a wear-resistant coating can be applied to the inner wall of the receiving hopper 17. Since the coating may cause some wear to the inner wall when it enters the receiving hopper 17, the wear-resistant coating can effectively reduce the wear of the inner wall of the receiving hopper 17 and extend the service life of the receiving hopper 17. At the same time, a buffer pad (not shown in the figure) can be installed at the receiving port of the vertical grinding machine body 1. The lower part of the receiving hopper 17 contacts the buffer pad. When the vibrating motor 6 drives the receiving hopper 17 to vibrate, the buffer pad can play a buffering role, reduce the collision between the receiving hopper 17 and the vertical grinding machine body 1, reduce noise, and further protect the vertical grinding machine body 1 and the receiving hopper 17.

[0027] Implementation effect: By setting a filter box 4 above the feed inlet of the vertical grinder body 1 and inserting a sieve frame 11 with a screen 12 into the filter box 4, the coating entering the grinder can be effectively filtered to remove impurities, avoid impurities from affecting the grinding effect and the service life of the internal components of the grinder, and improve the coating quality and the stability of equipment operation.

[0028] The handle 10 installed on the pull plate 9 and the push plate 8 installed on the middle right side of the moving plate 14 make it easy for workers to disassemble and install the screen frame 11. When it is necessary to clean the impurities on the screen 12 or to replace the screen 12, the workers only need to push the push plate 8 upward. The push plate 8 drives the moving plate 14 to move upward, compressing the second spring 15, so that the locking block 13 disengages from the locking groove of the pull plate 9. Then, the screen frame 11 can be pulled out through the handle 10. This design makes it easier to disassemble the screen frame 11 and clean the impurities on the screen 12. The operation is simple and saves time and manpower.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
