[0034] like Figure 1-11 As shown:

[0035] A waterproof coating preparation device comprises a fixed arc plate 101, and side ring plates 102 fixed on both sides of the fixed arc plate 101, an oblique cavity plate 103 extends from the upper end of the fixed arc plate 101, and an addition pipe 104 extends from the oblique cavity plate 103 to the end away from the fixed arc plate 101, an auxiliary arc plate 201 is arranged between the lower end of the fixed arc plate 101 and the addition pipe 104, and the auxiliary arc plate 201 is coaxially arranged with the fixed arc plate 101, and side circular plates 301 are fixed on the outer sides of the two side ring plates 102, and a central tube 302 rotates between the two side circular plates 301, and the central tube 302 rotates with the fixed arc plate 101. The fixed arc plate 101 is coaxially arranged, and a plurality of stirring arc plates 303 are circumferentially fixed on the central tube 302. The inner ends of the plurality of stirring arc plates 303 are tangentially arranged on the central tube 302, and the outer ends of the plurality of stirring arc plates 303 slide in contact with the inner wall of the fixed arc plate 101. A plurality of open grooves 304 are provided on the plurality of stirring arc plates 303. A scraper 401 slides through the inclined cavity plate 103, and a spring I 402 is provided between the upper end of the scraper 401 and the inclined cavity plate 103, so that the scraper 401 slides toward the central tube 302 and then presses against the outer side of the stirring arc plate 303.

[0036] The device forms a horizontal cylindrical stirring chamber through the auxiliary arc plate 201, the fixed arc plate 101 and the two side circular plates 301. The adding pipe 104 is used to add raw materials. After the raw materials are added into the stirring chamber, the first motor installed on the side circular plate 301 is started to drive the central tube 302, thereby driving the multiple stirring arc plates 303 to stir in the stirring chamber, and the rotation direction is in the same direction as the arc of the stirring arc plate 303, so that the lower end of the stirring chamber is pushed upward through the outer side of the stirring arc plate 303, and in the pushing process, the raw materials flow back to the lower end of the stirring chamber through the open groove 304, thereby forming stirring and mixing;

[0037] When the stirring arc plate 303 rotates to the upper side, it will contact with the scraper 401 and squeeze the scraper 401 to slide upward. During this process, the scraper 401 will scrape the outer side of the stirring arc plate 303, thereby preventing the raw materials from adhering to the outer side of the stirring arc plate 303. When the scraper 401 passes over the stirring arc plate 303, the scraper 401 is affected by the elastic force of the spring I 402 to quickly slide toward the center tube 302 and hit the center tube 302, thereby causing the stirring arc plate 303 to vibrate, and then the raw materials adhering to the inner side of the stirring arc plate 303 fall off, further preventing the raw materials from adhering to the stirring frame;

[0038] Moreover, by keeping the stirring arc plate 303 away from the end of the central tube 302 and the inner walls of the auxiliary arc plate 201 and the fixed arc plate 101, the raw materials are prevented from adhering to the inner wall of the stirring chamber, thereby achieving the purpose of ensuring the stirring effect.

[0039] like Figure 1-11 As shown:

[0040] Two limiting slide posts 403 are fixed on the side of the scraper 401, and comb plates 405 are slidably arranged on the two limiting slide posts 403. The comb teeth on the comb plates 405 correspond one-to-one to the multiple open grooves 304 on each stirring arc plate 303. The comb plates 405 and the limiting slide posts 403 are provided with springs II 404 to make the comb plates 405 slide toward the center tube 302.

[0041] When the stirring arc plate 303 contacts and lifts up the scraper plate 401, the elastic force of the spring II 404 will push the comb plate 405 into the multiple open grooves 304 on the stirring arc plate 303, thereby forming a scrape on the inner wall of the multiple open grooves 304 on the stirring arc plate 303, and then preventing the raw materials from adhering to the open grooves 304, ensuring that the raw materials will not adhere to the stirring frame and affect the stirring effect.

[0042] like Figure 1-11 As shown:

[0043] Two support frames 106 are fixed to the lower ends of the two side ring plates 102. A plurality of transmission wheels 501 are rotated through the lower part of the fixed arc plate 101. A stirring edge frame 502 is connected to each of the plurality of transmission wheels 501. The plurality of stirring edge frames 502 correspond one by one to the plurality of open grooves 304 on each stirring arc plate 303.

[0044] Two support frames 106 form support for the device. A second motor installed on one of the support frames 106 simultaneously drives multiple transmission wheels 501, thereby driving multiple stirring ribs 502 to rotate, thereby pushing the raw materials to the multiple stirring ribs 502 on the stirring arc plate 303, and allowing the multiple stirring ribs 502 to pass through the multiple open grooves 304, thereby further improving the stirring efficiency.

[0045] Further:

[0046] The virtual axis extension line of the stirring rib 502 intersects with the axis of the central tube 302, thereby ensuring that the stirring rib 502 can fully occupy the open groove 304 for stirring, thereby ensuring the stirring effect.

[0047] like Figure 1-11 As shown:

[0048] A plurality of stirring edge racks 502 are provided with a horizontal plate 503 which is rotated away from the end of the central tube 302 , and an electric telescopic rod is provided between the horizontal plate 503 and the fixed arc plate 101 .

[0049] By starting the electric telescopic rod to reciprocate and retract, multiple stirring ribs 502 can be driven to slide back and forth in multiple transmission wheels 501 at the same time, so that the stirring ribs 502 penetrate the transmission wheels 501, and the raw materials adhered to the surface of the stirring ribs 502 can be scraped, further improving the stirring effect.

[0050] like Figure 1-11 As shown:

[0051] An arc plate frame 203 is fixed to the outer side of the auxiliary arc plate 201 , and two ends of the arc plate frame 203 penetrate and slide through the two side ring plates 102 respectively.

[0052] The auxiliary arc plate 201 can rotate coaxially on the two side ring plates 102 through the arc plate frame 203, thereby separating the lower end of the auxiliary arc plate 201 from the lower end of the fixed arc plate 101, thereby causing an opening to appear between the fixed arc plate 101 and the auxiliary arc plate 201, and thereby causing an opening to appear at the lower end of the stirring chamber, thereby allowing the paint to be discharged.

[0053] Further:

[0054] An adjusting screw 205 is rotatably mounted on the adding pipe 104 , a threaded block 204 is threadedly connected to the adjusting screw 205 , and a linkage plate 206 is rotatably mounted between the threaded block 204 and the arc plate frame 203 .

[0055] By rotating the adjusting screw 205, the threaded block 204 can be threadedly driven to move up and down, thereby driving the arc plate frame 203 to rotate coaxially on the two side ring plates 102 through the linkage plate 206, and then driving the auxiliary arc plate 201 to rotate upward.

[0056] Further:

[0057] A vertical plate 105 extends from the lower end of the fixed arc plate 101 , and a matching plate 202 extends from the lower end of the auxiliary arc plate 201 .

[0058] By disposing the vertical plate 105 and the matching plate 202, when the fixed arc plate 101 is separated from the auxiliary arc plate 201, the vertical plate 105 and the matching plate 202 cooperate with the two side ring plates 102 to form a discharge channel for easy centralized collection.

[0059] A waterproof coating preparation process, the process comprising the following steps:

[0060] S1. Mixing equal amounts of anhydrous sodium sulfate and water-soluble silicone oil, stirring, filtering, drying and crushing to obtain a powder;

[0061] S2, adding powder, cement, latex powder and polypropylene anti-cracking agent into the auxiliary arc plate 201 and the fixed arc plate 101 through the adding pipe 104 to form a mixing chamber;

[0062] S3, driving multiple stirring arc plates 303 to rotate in the mixing chamber through the central tube 302 to stir, and scraping the stirring arc plates 303 through the scraper 401 to prevent the raw materials from being retained on the stirring arc plates 303;

[0063] S4. After uniform mixing, a waterproof coating is obtained.

[0064] The coating prepared by the process comprises the following raw materials in parts by weight: 20-30 parts of powder, 3-5 parts of latex powder, 0.5-1 part of polypropylene anti-cracking agent, and 25-50 parts of cement.
