[0002] As a common chemical product, coatings are widely used in machinery, construction and other industries. By applying coatings with different functions to the target object, it can be given effects that it originally did not have, such as waterproofing, rust-proofing, and reflection.

[0003] At present, when producing paint, it is necessary to mix a variety of materials. Since the paint itself has a certain viscosity and its fluidity is poor compared to liquid, the current conventional stirring and mixing devices have poor mixing effect. It is easy for paint auxiliary materials to be distributed and mixed on the upper layer of the paint base material, and it is difficult to penetrate into the bottom layer of the paint to achieve all-round mixing, resulting in poor mixing effect. More time is required to ensure uniform mixing, which does not meet the needs of efficient and high-quality production. Summary of the invention

DETAILED DESCRIPTION

[0032] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0033] Example 1: Figure 1-6 As shown, a coating manufacturing system comprises a tank body 1 and a control panel, wherein the upper and lower ends of the tank body 1 are respectively provided with a feed port 11 and a discharge port 12, a stirring mechanism is provided in the middle of the tank body 1, and a blending mechanism matching the stirring mechanism is provided inside the tank body 1;

[0034] The stirring mechanism includes a motor 2 and a stirrer. The motor 2 is arranged at the upper end of the tank body 1. The stirrer is arranged in the tank body 1 and is drivingly connected to the output shaft of the motor 2. The number of the blending mechanisms is several and they are evenly arranged in the tank body 1 around the axis of the tank body 1.

[0035] The blending mechanism includes an inner tank 3, a plug body 31 and a driver. The inner tank 3 is fixedly connected to the inside of the tank body 1 through a bracket. The plug body 31 is slidingly sealed in the tank body 1 through guide ribs. The driver is arranged in the tank body 1 and rotates to seal and extend out of the tank body 1. The plug body 31 is rotationally sealed and connected to the driver. The upper and lower ends of the inner tank 3 are both provided with a one-way liquid inlet valve and a discharge pipe 32. The discharge pipes 32 at the upper and lower ends extend to the opposite side of themselves relative to the end of the inner tank 3 and are provided with a plurality of one-way liquid discharge valves.

[0036] When preparing the coating, the coating base material and coating auxiliary material to be mixed are injected into the tank body 1, and then the stirring mechanism is turned on through the control panel. At this time, the motor 2 starts to drive the stirrer to mix and stir the coating in the tank body 1. Since the coating has a certain viscosity and its fluidity is not as good as that of liquid, in order to improve the mixing effect and efficiency, during the operation of the stirring mechanism, the stirrer will synchronously drive the blending mechanism to operate, wherein the stirrer drives the driver so that the driver controls the plug 31 to displace in the inner tank 3, that is, the plug 31 produces an up and down reciprocating motion in the inner tank 3. Since the upper and lower ends of the inner tank 3 are both provided with a one-way liquid inlet valve and a drain pipe 32 provided with a one-way liquid drain valve, during the movement of the plug 31, the plug 31 will use the negative pressure or extrusion force generated by the displacement to extract the coating in the tank body 1, wherein the coating discharged by the drain pipe 32 is discharged toward the other side of its own extraction range, so that the coating can be exchanged at a horizontal height, and the stirring mechanism can be used to mix more effectively, thereby improving the uniformity and efficiency of the mixing.

[0037] The agitator includes a main shaft 21, stirring blades 22 and middle blades 23. The main shaft 21 is rotatably arranged in the tank body 1. The number of stirring blades 22 is several and they are evenly arranged along the length direction of the main shaft 21. The middle blade 23 is arranged in the middle of the main shaft 21. With the middle blade 23 as the center line, the mixing mechanisms arranged on the upper and lower sides of the middle blade 23 are symmetrically distributed.

[0038] The driver includes a rotating shaft 4 and a driving blade 41. One end of the rotating shaft 4 is rotatably connected to the inner wall of the inner tank 3 away from the middle blade 23. The rotating shaft 4 rotates and seals through the other end of the inner tank 3. There are several driving blades 41 that are evenly arranged on the rotating shaft 4. The distance from the end of the middle blade 23 to the edge of the rotating shaft 4 is smaller than the distance from the end of the driving blade 41 to the edge of the rotating shaft 4.

[0039] A guide groove 42 is formed on the side of the rotating shaft 4 . The guide grooves 42 are connected end to end. The guide grooves 42 present a sine wave structure when unfolded in a plane. A transmission head 43 that fits in the guide groove 42 is provided on the inner side of the plug body 31 .

[0040] The upper and lower ends of the inner tank 3 and the upper and lower ends of the plug body 31 are both provided with elastic covers 44 sleeved with the rotating shaft 4 .

[0041] When the stirring mechanism is stirring, the main shaft 21, driven by the motor 2, will use the stirring blades 22 to mix and stir the paint in the tank body 1, and the middle blades 23 will rotate synchronously with the main shaft 21. At this time, the middle blades 23 will move the driving blades 41 in the driver, thereby causing the rotating shaft 4 to rotate. By driving the guide grooves 42 on the side of the rotating shaft 4 and the transmission head 43 of the plug body 31, the plug body 31 can generate an up and down circulation movement in the inner tank 3, thereby exchanging and mixing the paints in the upper and lower positions in the tank body 1, wherein the elastic cover 44 can shield the rotating shaft 4. On the one hand, it does not affect the movement of the plug body 31, and on the other hand, it can protect the rotating shaft 4. The elastic cover 44 can be a rubber cover or a corrugated cover.

[0042] Embodiment 2: An auxiliary agitator is also provided between the plug body 31 and the inner tank 3. There are two auxiliary agitators which are symmetrically arranged at the upper and lower ends of the plug body 31. The auxiliary agitator comprises a spring 5, a connecting ring 51 and a compound leaf 52. There are two connecting rings 51, one of which is fixedly connected to the end of the rotating shaft 4 on the corresponding side, and the other connecting ring 51 is coaxially rotatably sealed with the plug body 31. The spring 5 is fixedly arranged between the two connecting rings 51 and is sleeved on the rotating shaft 4. The elastic cover 44 is connected to the inner ring side of the spring 5. The spiral rotation directions of the two springs 5 ​​in the same inner tank 3 are opposite and the rotation direction of the rotation and winding is matched with the rotation direction of the rotating shaft 4. There are several compound leaves 52 which are evenly arranged on the spring 5 along the axial direction of the rotating shaft 4.

[0043] The discharge pipe 32 is provided with an arc tube offset between the stirring blade 22 and the middle blade 23 at a position corresponding to the one-way discharge valve. The arc tube is concentric with the tank body 1 and extends to the side. The arc tube is evenly provided with a plurality of discharge ports.

[0044] In order to further improve the efficiency and effect of stirring, when the blending mechanism extracts the coating solution in the tank body 1, the rotation of the rotating shaft 4 will drive the connecting ring 51 connected thereto to rotate. Since the spring 5 itself has a certain torsional resistance, when the rotating shaft 4 drives the plug body 31 to move, the spring 5 will rotate relative to the plug body 31. In order to prevent the elastic cover 44 from twisting due to rotation and sticking to the rotating shaft 4 to affect the movement or rupture of the plug body 31, the connecting ring 51, which is rotatably sealed with the plug body 31, will rotate synchronously with the rotating shaft 4 after the rotating shaft 4 drives the spring 5 to rotate until the torsional driving force is greater than the rotation resistance. At this time, the rotating shaft 4, the two connecting rings 51, the spring 5 and the elastic cover 44 all rotate, thereby maintaining relative stillness, and the compound leaves 52 arranged on the side of the spring 5 will mix the coating solution in the inner tank 3;

[0045] The spring 5 will be compressed due to the displacement of the plug 31, wherein the distance between the end of the plug 31 and the inner tank 3 means the amount of solution in the inner tank 3. At this time, the compression and extension of the spring 5 are synchronized with the displacement of the plug 31. In this way, when the coating solution is extracted and the amount gradually increases, the spring 5 can be expanded so that the compound leaves 52 are more dispersedly distributed in the solution of the inner tank 3 on the corresponding side, thereby improving the mixing effect and better meeting the mixing needs.

[0046] A coating manufacturing method, the specific method is as follows:

[0047] Step 1: inject the coating base material into the tank through the feed port, start the agitator through the control panel to stir, and inject the remaining coating auxiliary materials into the tank through the feed port;

[0048] Step 2: During the stirring process, the agitator preliminarily mixes the coating base material and the coating auxiliary material, and at the same time drives the blending mechanism to pump and exchange the coating at the upper and lower heights in the tank. The stirring time is 45-60 minutes and the speed is 200-400rpm;

[0049] Step 3: Keep the paint in the tank warm while stirring, keep it warm for 30 minutes after stirring is completed, and finally discharge it through the discharge port to complete the preparation.

[0050] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
