[0032] Example 1

[0033] like Figures 1-3 As shown, the present invention proposes a water-based paint pretreatment device, which includes a cylinder, a feed inlet 4, a support frame 9, a guide block 14, and a stirring assembly.

[0034] The support frame 9 is installed inside the cylinder and near the top. The top of the support frame 9 is provided with a screen 7 for screening water-based paint raw materials during use.

[0035] The agitation component is installed at the top center of the cylinder and extends from the bottom end through the center of the support frame 9 to the bottom end of the inner side of the cylinder. The bottom end of the agitation component and the bottom end of the support frame 9 are provided with a striking component 10 for striking the bottom end of the support frame 9 in the use state.

[0036] The feed inlet 4 is installed at the top of the cylinder and is located on one side of the agitator and connected to the cylinder. The number of feed inlets 4 is at least one.

[0037] There is at least one guide block 14, which is installed at the bottom of the support frame 9 and located in the movement path of the striking assembly 10.

[0038] In this embodiment, water-based paint raw materials are added to the top of the screen 7 inside the cylinder through the feed inlet 4. The shape of the screen 7 and the number of feed inlets 4 are multiple to improve the screening efficiency of the water-based paint raw materials. By activating the stirring component, the stirring component drives the striking component 10 to rotate at the bottom of the support frame 9. During the rotation, the guide block 14 guides the end of the striking component 10, causing the striking component 10 to bend at the guide block 14 and reset when it rotates behind the guide block 14. The force of the striking component 10 resetting strikes the support frame 9, causing the support frame 9 to drive the screen 7 to resonate, so that the screen 7 performs the screening work of water-based paint raw materials. At the same time, the raw materials fall into the inner side of the cylinder body 1 and are stirred by the stirring component, so that the water-based paint raw materials are mixed.

[0039] Example 2

[0040] like Figure 1 As shown, the present invention proposes a water-based paint pretreatment device. Compared with the first embodiment, the difference in this embodiment is that the cylinder includes a cylinder body 1, bolts 2 and a top cover 3.

[0041] The inner side of the cylindrical body 1 has a cavity;

[0042] The top cover 3 is placed on the top of the cylinder body 1 and fixedly connected to the cylinder body 1 by bolts 2.

[0043] In this embodiment, the cylinder body 1 and the upper cover 3 are detachably connected by bolts 2, which makes it easier to clean the filtered material on the screen 7 and maintain the inside of the cylinder body 1.

[0044] Example 3

[0045] like Figure 2 As shown, the present invention proposes a water-based paint pretreatment device. Compared with the first embodiment, the difference in this embodiment is that the support frame 9 is provided with a sleeve 8 extending to the bottom end of the upper cover 3 in the middle, and a connecting ring 6 is provided at the bottom end of the upper cover 3. The connecting ring 6 is inserted into the inner side of the sleeve 8 to block the water-based paint raw materials during use and prevent unscreened raw materials from being directly added to the cylinder body 1.

[0046] In an optional embodiment, guide rings 13 are provided on both the inner and outer sides of the top of the screen 7. The two guide rings 13 are respectively attached to the outer wall of the sleeve 8 and the inner wall of the cylinder body 1 to prevent the accumulation of water-based paint raw materials on the inner and outer sides of the top of the screen 7.

[0047] In this embodiment, by setting guide rings 13 on the inner and outer sides of the top of the screen 7, the guide rings 13 guide the water-based paint coating to the middle of the top of the screen 7, and by cooperating with the sleeve 8 and the connecting ring 6, the water-based paint coating material is prevented from falling directly to the inner side of the cylinder body 1.

[0048] Example 4

[0049] like Figure 2 As shown, the water-based paint pretreatment device proposed in this utility model differs from the first embodiment in that the stirring component includes a motor 5, a rotating rod 11, and a stirring blade 12.

[0050] The rotating rod 11 is rotatably installed in the middle of the upper cover 3 and its bottom end extends toward the inner bottom end of the cylinder body 1;

[0051] The motor 5 is mounted on the top of the upper cover 3 and is connected to the rotating rod 11 for transmission.

[0052] There are multiple stirring blades 12, and all of the stirring blades 12 are installed at the bottom end of the rotating rod 11 and located inside the cylinder body 1.

[0053] In an optional embodiment, the width of the stirring blade 12 is smaller than the inner diameter of the sleeve 8, which makes it easier to disassemble the rotating rod 11 during use.

[0054] In this embodiment, the motor 5 drives the rotating rod 11 to rotate inside the cylinder body 1, so that the rotating rod 11 drives the striking component 10 to work. At the same time, the rotating rod 11 drives the stirring blade 12 to stir the water-based paint coating material inside the cylinder body 1.

[0055] Example 5

[0056] like Figure 3 As shown, the present invention proposes a water-based paint pretreatment device. Compared with the first embodiment, the difference in this embodiment is that the striking component 10 includes a roller 102, a spring 103 and a mounting sleeve 104.

[0057] Mounting sleeve 104 is fitted onto the outside of rotating rod 11;

[0058] There are multiple springs 103, which are arranged at equal angles on the outside of the mounting sleeve 104 and extend toward the bottom of the support frame 9.

[0059] The roller 102 is mounted on one end of the spring 103 and located at the bottom of the support frame 9, and is in rolling connection with the support frame 9.

[0060] In an optional embodiment, the outer side of the roller 102 is covered by a connecting sleeve 101.

[0061] In this embodiment, the mounting sleeve 104 is connected to the rotating rod 11. When the rotating rod 11 drives the mounting sleeve 104 to rotate, the mounting sleeve 104 drives the roller 102 to roll at the bottom of the support frame 9 through the spring 103. When it rolls to the guide block 14, the spring 103 bends due to the shape of the guide block 14. When it moves behind the guide block 14, the spring 103 rebounds and drives the roller 102 to collide with the bottom of the support frame 9, causing the support frame 9 to vibrate and causing the screen 7 to resonate. At the same time, the sharp noise between the roller 102 and the support frame 9 is reduced by wrapping the connecting sleeve 101 around the outside of the roller 102.

[0062] In this invention, water-based paint raw materials are added to the top of the screen 7 inside the cylinder body 1 through the feed inlet 4. The multiple feed inlets 4, due to the shape of the screen 7, allow a large amount of raw material to be added to the top of the screen 7 simultaneously, improving the screening efficiency of the water-based paint raw materials. The motor 5 is started, causing the rotating rod 11 to rotate inside the cylinder body 1. The rotating rod 11 is connected to the mounting sleeve 104, so that when the rotating rod 11 drives the mounting sleeve 104 to rotate, the mounting sleeve 104... Spring 103 drives roller 102 to roll at the bottom of support frame 9. When it rolls to guide block 14, spring 103 bends due to the shape of guide block 14. When it moves behind guide block 14, spring 103 rebounds and drives roller 102 to collide with the bottom of support frame 9, causing support frame 9 to vibrate and drive screen 7 to resonate, so that screen 7 can screen the raw materials. At the same time, rotating rod 11 drives stirring blade 12 to stir the water-based paint raw materials screened inside cylinder body 1.

[0063] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
