[0017] The following is in conjunction with the appendix Figure 1-4 The present invention will be further described below.

[0018] In order to solve the problems existing in the background art, this application proposes the following technical solution: a premixing device for preparing waterproof superoleophobic resin coatings.

[0019] The specific technical solution includes a mixing tank 1, a scraping assembly 2, and a scraping and stirring assembly 3; like Figure 1-4As shown, the scraper assembly 2 is installed on the mixing tank 1. The scraper assembly 2 is used to scrape off the paint. The scraper assembly 2 includes a scraper 201, a sealing ring 202, a central cylinder 203, a top plate 204, and a linear cylinder 205. The scraper 201 supports the sealing ring 202, and the sealing ring 202 improves the sealing between the outer sidewall of the scraper 201 and the inner sidewall of the mixing tank 1. The scraper 201 and the sealing ring 202 can scrape off the paint adhering to the inner sidewall of the mixing tank 1. The central cylinder... 203 facilitates the connection between scraper 201 and top plate 204. Top plate 204 supports the central cylinder 203. Linear cylinder 205 drives the top plate 204 to rise and fall. Sealing ring 202 is fixedly sleeved on the outside of scraper 201 and slidably installed inside mixing tank 1. Central cylinder 203 is fixedly installed above scraper 201. Top plate 204 is fixedly sleeved on the outside of central cylinder 203. The telescopic end of linear cylinder 205 connects to top plate 204. The bottom surface is fixedly connected; the scraper and agitator assembly 3 is installed on the scraper 201. The scraper and agitator assembly 3 is used for agitating and scraping the paint. The scraper and agitator assembly 3 includes a linear cylinder 301, a top plate 302, an agitator shaft 303, a torsion spring 304, and an agitator rod 305. The linear cylinder 301 can drive the top plate 302 to rise and fall. The top plate 302 can support the agitator shaft 303. The agitator shaft 303 can support the agitator rod 305. The torsion spring 304 can drive the agitator rod 305. 05 Reset, the stirring rod 305 rotates to mix the materials inside the mixing tank 1, the top plate 2 302 is fixedly installed above the telescopic end of the linear cylinder 2 301, the stirring shaft 303 rotates and passes through the bottom of the top plate 2 302, the stirring shaft 303 passes through the middle part of the scraper 201 and the central cylinder 203, the torsion spring 304 is located inside the stirring shaft 303, the stirring rod 305 rotates and passes through the bottom of the stirring shaft 303, and the two ends of the torsion spring 304 are fixedly connected to the stirring shaft 303 and the stirring rod 305.

[0020] After the mixed paint inside the mixing tank 1 is discharged, the inner wall of the mixing tank 1 below the scraper 201, the bottom surface of the scraper 201, the outer wall of the stirring shaft 303 below the scraper 201, and the outer wall of the stirring rod 305 are all covered with paint. By activating the linear cylinder 301, the top plate 302 is raised, which in turn raises the stirring shaft 303. The stirring shaft 303 can slide and rise along the center of the scraper 201 inside the central cylinder 203, with the outer wall of the stirring shaft 303 tightly attached to the center of the scraper 201. The coating on the inner wall of the mixing tank 1 and the inner wall of the central cylinder 203 can be scraped off and fall into the scraper 201 inside the mixing tank 1. When the mixing shaft 303 rises, it drives the torsion spring 304 and the mixing rod 305 to rise. When the mixing rod 305 contacts the scraper 201, due to the upward pulling force given by the mixing shaft 303, the mixing rod 305 and the bottom surface of the scraper 201 are pressed against each other, so the mixing rod 305 can rotate around the central axis of the part connected to the mixing shaft 303. The mixing shaft 303 is provided with mutual... The two symmetrical stirring rods 305 rotate downwards at their ends away from the stirring shaft 303. The two stirring rods 305 close and move towards the scraper 201 and the central cylinder 203 via the scraper 201. After closing, the two stirring rods 305 form a cylindrical structure and press against each other. The paint adhering to the surfaces where the two stirring rods 305 press against each other is squeezed out. The diameter of the cylindrical structure formed after the two stirring rods 305 close is the same as the inner diameter of the scraper 201 and the central cylinder 203. The two stirring rods 305 retract into the central cylinder 203. The external coating can be scraped off by the scraper 201, which can fully scrape off the coating on the outside of the stirring shaft 303 and the stirring rod 305. The stirring rod 305 can completely fill the center of the scraper 201 and its bottom surface is flush with the bottom surface of the scraper 201. When the two stirring rods 305 are closed, they twist the torsion spring 304. The torsion spring 304 can give the stirring rods 305 a reverse thrust. When the stirring rods 305 move downward out of the scraper 201 and the central cylinder 203, the torsion spring 304 can drive the two stirring rods 305 to unfold.

[0021] After the stirring rod 305 is fully retracted into the scraper 201 and the central cylinder 203, the linear cylinders 205 and 301 are simultaneously activated. The linear cylinders 205 and 301 respectively lower the top plate 204 and 302, which in turn lower the central cylinder 203 and the stirring shaft 303. The central cylinder 203 and the stirring shaft 303 then lower the scraper 201 and the stirring rod 305. 201 drives the sealing ring 202 to descend, and the scraper 201, sealing ring 202, central cylinder 203, top plate 1 204, top plate 2 302, stirring shaft 303, torsion spring 304 and stirring rod 305 descend synchronously. The scraper 201 and sealing ring 202 can scrape the coating inside the mixing tank 1 downwards. When the bottom surface of the scraper 201 presses against the bottom surface inside the mixing tank 1, the remaining coating inside the mixing tank 1 can be completely squeezed out, allowing the coating to enter the discharge pipe 9.

[0022] like Figure 1 and Figure 4 As shown, a servo motor 4 is fixedly installed above the top plate 302. The servo motor 4 can drive the stirring shaft 303 to rotate. The output shaft of the servo motor 4 is fixedly connected to the stirring shaft 303.

[0023] By starting the servo motor 4, the stirring shaft 303 is driven to rotate, which in turn drives the stirring rod 305 to rotate. The stirring rod 305 can mix and stir the coating inside the mixing tank 1.

[0024] like Figure 2 As shown, the bottom surface of the scraper 201 has a groove 5, which can conveniently accommodate the baffle 6. The baffle 6 is fixedly installed on the stirring rod 305. When the stirring rod 305 is retracted into the scraper 201 and the central cylinder 203, the rising of the stirring rod 305 can drive the baffle 6 to rise. When the baffle 6 and the scraper 201 are pressed against each other, by starting the servo motor 4, according to the above steps, the rotation of the stirring rod 305 can drive the baffle 6 to rotate. The baffle 6 rises and rotates at the same time, which can retract the baffle 6 into the groove 5. At this time, the stirring rod 305 is completely inserted into the scraper 201 and the central cylinder 203. The baffle 6 can prevent the bottom of the stirring rod 305 from being higher than the scraper 201, and prevent the stirring rod 305 from detaching from the scraper 201 and the central cylinder 203.

[0025] like Figure 1 and Figure 4 As shown, a top cover 7 is fixedly installed on the top of the mixing tank 1. The top cover 7 can cover the upper opening of the mixing tank 1 and prevent the scraper 201 from detaching from the mixing tank 1 when it rises. The central cylinder 203 is slidably inserted through the center of the top cover 7.

[0026] like Figure 1 and Figure 4As shown, a feed hopper 8 is fixedly installed on the side wall of the mixing tank 1. The material is poured into the feed hopper 8 and the material inside the feed hopper 8 enters the mixing tank 1 and is located below the scraper 201, which can facilitate the mixing of different materials and then prepare coatings.

[0027] like Figure 4 As shown, a discharge pipe 9 is fixedly installed at the bottom of the mixing tank 1, and the mixed paint can be discharged from the discharge pipe 9 and then used.

[0028] like Figure 1 and Figure 4 As shown, a support leg 10 is fixedly sleeved below the mixing tank 1, which can support the mixing tank 1. The fixed ends of linear cylinder 1 205 and linear cylinder 2 301 are fixedly installed above the support leg 10, which can support the fixed ends of linear cylinder 1 205 and linear cylinder 2 301.
