Description

Technical Field

[0001] This invention relates to the field of coating preparation technology, and more specifically to a system and method for preparing water-based coating compositions. Background Technology

[0002] Application number 201920830160.7 discloses a mixing device for a matte powder coating composition that facilitates mixing. The base has support columns welded to both ends at its top. The top of the two support columns, which are close to each other, is connected to a mixing tank via bearings and a rotating shaft. A cap is hinged to one end of the mixing tank's opening. An installation groove is formed in the center of the top of the cap, and a mixing box is bolted inside the installation groove. The bottom of the mixing box has evenly spaced discharge holes. When matte powder is added through the matte powder feed pipe, the drive motor disperses the powder clumps via a dispersing rod, ensuring sufficient contact between the matte powder and the dispersed coating. This prevents the powder clumps from affecting the mixing of the matte powder coating. After mixing is complete inside the mixing tank, the locking bolts are loosened to pour out the coating, making it convenient for workers to use. However, this device cannot handle clumps of coating during the mixing process. Summary of the Invention

[0003] To overcome the shortcomings of the prior art, the present invention provides a system and method for preparing water-based coating compositions. The beneficial effect is that it can crush the agglomerated coatings in the water-based coating composition during the preparation process, thereby improving the quality of the water-based coating composition.

[0004] The technical solution adopted by this invention to solve its technical problem is:

[0005] A water-based coating composition preparation system includes a cylindrical body. A filter box and a drive unit are fixedly connected to the left side of the inner side of the cylindrical body. A mandrel is rotatably connected to the middle of the cylindrical body. A ring frame is fixedly connected to the mandrel away from the drive unit inside the cylindrical body. Two rotatable shafts are symmetrically rotatably connected to the ring frame. A collection filter box is fixedly connected to each of the two shafts. A scraper is fixedly connected to each of the two collection filter boxes. During the rotation of the collection filter boxes driven by the ring frame, the scraper can transport the agglomerated coating into the filter box. Two rollers are symmetrically installed on the ring frame. The drive unit can drive the upper roller to crush the agglomerated coating inside the filter box. A valve is connected to the lower end of the cylindrical body.

[0006] Two ribs are symmetrically fixed to the ring frame, and a column is fixed to each of the two ribs. A compression spring is sleeved on each of the two column. The roller includes a slide that is simultaneously slidably connected to the ribs and column on the same side. A pressure roller is fixed to the slide. The two ends of the compression spring are respectively fixed to the ribs and slide on the corresponding sides.

[0007] The drive component includes a side frame fixed to the inner wall of the cylinder, and an arc-shaped groove is formed on the side frame at the upper end of the filter box. A round rod that can enter the groove is fixed to the pressure roller.

[0008] Two sleeves are symmetrically fixed to the ring frame, and two rotating shafts are coaxial with the two sleeves respectively. Multiple spring plates are fixedly connected around the sleeves and rotating shafts on the same side.

[0009] A rack is fixedly connected to the upper end of the inner wall of the cylinder away from the slide groove, and gears that can mesh with the rack are fixedly connected to both of the rotating shafts.

[0010] A method for preparing a waterborne coating composition using a waterborne coating composition preparation system includes the following steps:

[0011] a: Add the water-based coating composition into the cylinder;

[0012] b: The geared motor starts and drives the spindle to rotate. The spindle drives two collection filter boxes and two pressure rollers to make circular motion through the ring frame, which can homogenize the water-based coating composition.

[0013] c: Both scrapers are in contact with the inner wall of the cylinder. During the rotation of the scrapers, they can continuously scrape up the clumps of paint deposited on the bottom surface of the cylinder and collect them in the collection filter box.

[0014] d: When the gear meshes with the rack, it drives the collection filter box to rotate downwards, and the clumps of paint collected in the collection filter box fall into the filter box;

[0015] e: When the pressure roller rotates to the top, the round rod enters the chute, the chute presses the round rod to slide downward, thereby driving the pressure roller to slide downward into the filter box. The pressure roller slides along the inner wall of the filter box to crush the clumps of paint in the filter box, and the crushed paint falls back into the cylinder.

[0016] f: Repeat the process until there are no lumps of paint in the cylinder, then open the valve to discharge the mixed water-based paint composition. Attached Figure Description

Detailed Implementation

[0032] like Figures 1 to 13 As shown:

[0033] A water-based coating composition preparation system includes a cylindrical body 101. A filter box 104 and a drive component are fixedly connected to the left side of the interior of the cylindrical body 101. A spindle 201 is rotatably connected to the middle of the cylindrical body 101. A ring frame 203 is fixedly connected to the spindle 201, away from the drive component, inside the cylindrical body 101. Two rotatable shafts 401 are symmetrically rotatably connected to the ring frame 203. Collection filter boxes 403 are fixedly connected to both shafts 401, and scrapers 404 are fixedly connected to both collection filter boxes 403. During the rotation of the collection filter boxes 403 by the ring frame 203, the scrapers 404 can transport agglomerated coating material into the filter box 104. Two rollers are symmetrically installed on the ring frame 203. The drive component can drive the upper roller to crush the agglomerated coating material inside the filter box 104. A valve is connected to the lower end of the cylindrical body 101.

[0034] The water-based coating composition is added into the cylinder 101. The spindle 201 rotates, and the spindle 201 drives two collection filter boxes 403 and two rollers to perform circular motion via the ring frame 203. During the rotation of the two collection filter boxes 403 and the two rollers, the water-based coating composition can be homogenized. Both scrapers 404 are in contact with the inner wall of the cylinder 101. During the circular motion of the scrapers 404, they can continuously scoop up the clumps of coating material deposited on the bottom surface of the cylinder 101 and collect them in the collection filter boxes 403. Since the bottom surface of the collection filter box 403 is a filter screen, the clumps of coating material can be filtered out. When the collection filter box 403 rotates to the top of the filter box 104... The system controls the downward rotation of the collection filter box 403, causing the collected clumps of paint to fall into the filter box 104. When the roller rotates to the top, the drive unit can drive the roller to crush the clumps of paint inside the filter box 104. The crushed paint falls back into the cylinder 101, and the cycle repeats until there are no more clumps of paint in the cylinder 101. Then, the valve is opened to discharge the mixed water-based paint composition. The collection filter box 403 and the roller are staggered, so that after each batch of clumps of paint is added, the roller crushes it and discharges it from the filter box 104, preventing the accumulation of clumps of paint and thus affecting the treatment effect of clumps of paint.

[0035] like Figures 7 to 8 As shown:

[0036] Two ribs 204 are symmetrically fixed to the ring frame 203. A column rod 205 is fixed to each of the two ribs 204. A compression spring 206 is sleeved on each of the two column rods 205. The roller mill includes a slide 301 that is simultaneously slidably connected to the ribs 204 and column rods 205 on the same side. A pressure roller 302 is fixed to the slide 301. The two ends of the compression spring 206 are respectively fixed to the ribs 204 and slide 301 on the corresponding sides.

[0037] The compression spring 206 allows the slide 301 to slide on the prism bar 204, thereby giving the pressure roller 302 elasticity. Under normal conditions, the pressure roller 302 is located near the outer end of the ring frame 203. When the two pressure rollers 302 make circular motion, they can play a role in stirring and mixing the water-based coating composition. When the pressure roller 302 rotates to the top of the filter box 104, the round bar 303 is driven by external force to move the pressure roller 302 downward, thereby allowing the pressure roller 302 to enter the filter box 104 and crush the clumps of coating in the filter box 104. After the round bar 303 separates from the slide groove 107, the pressure roller 302 returns to its original position.

[0038] like Figures 8 to 10 As shown in Figure 11:

[0039] The driving component includes a side frame 106 fixed to the inner wall of the cylinder 101. An arc-shaped groove 107 is formed on the side frame 106 at the upper end of the filter box 104. A round rod 303 that can enter the groove 107 is fixed to the pressure roller 302.

[0040] When the pressure roller 302 rotates to the top of the filter box 104, the round rod 303 enters the slide groove 107. The arc of the slide groove 107 presses the round rod 303 to slide downward, thereby driving the pressure roller 302 to enter the filter box 104 downward, thus automatically crushing the clumps of paint in the filter box 104.

[0041] Further:

[0042] The arc of the groove 107 is equal to the arc of the filter box 104, so that the pressure roller 302 can slide against the inner wall of the filter box 104, thereby making full contact with the clumps of paint inside the filter box 104, and thus crushing them completely, improving the effect of crushing the clumps of paint.

[0043] like Figure 3 and 10 As shown:

[0044] The lower end of the side frame 106 is fixedly connected to a non-circular rod 105, and the non-circular rod 105 has multiple arc surfaces formed on it.

[0045] Because the pressure roller 302 is elastic, when the pressure roller 302 rotates downward, the round rod 303 contacts the arc surface on the shaped rod 105, and the round rod 303 slides along the arc surface, thereby causing the position of the pressure roller 302 to change, thereby agitating the water-based coating composition in different parts and improving the mixing effect of the water-based coating composition.

[0046] Further:

[0047] The two adjacent arc surfaces on the irregular rod 105 have different degrees of protrusion;

[0048] The pressure roller 302, which is moving in a circular motion, changes position to different degrees under the drive of the round rod 303, thereby further stirring the water-based coating composition in different parts, promoting the rapid precipitation of agglomerated substances, and then filtering and crushing them.

[0049] like Figure 12 As shown:

[0050] Two sleeves 207 are symmetrically fixed on the ring frame 203, and two rotating shafts 401 are coaxial with the two sleeves 207 respectively. Multiple spring plates 402 are fixedly connected around the sleeves 207 and rotating shafts 401 on the same side.

[0051] The elastic force of multiple spring plates 402 prevents relative rotation between the sleeve 207 and the rotating shaft 401 under normal conditions. As a result, when the collection filter box 403 makes a circular motion, the scraper 404 can scoop up the deposited clumps of paint and rotate upward along the collection filter box 403. The scooped-up paint clumps fall into the collection filter box 403 for collection, and the excess paint is filtered out by the collection filter box 403, thereby separating the clumps of paint.

[0052] like Figure 1 , 3 As shown in 12 and 13:

[0053] A rack 103 is fixedly connected to the upper end of the inner wall of the cylinder 101 away from the slide groove 107, and a gear 405 that can mesh with the rack 103 is fixedly connected to each of the two rotating shafts 401.

[0054] The ring frame 203 rotates in the direction of the scraper 404's inclination, which is referenced to... Figure 1 From the perspective of the ring frame 203, it rotates counterclockwise. When the gear 405 meshes with the rack 103, it drives the gear 405 to rotate. The gear 405 drives the rotating shaft 401 to rotate clockwise. The rotating shaft 401 drives the collection filter box 403 to rotate downward, so that the paint collected in the collection filter box 403 falls into the filter box 104. When the gear 405 separates from the rack 103, the collection filter box 403 automatically resets under the action of multiple spring plates 402.

[0055] like Figure 1 , 4 As shown in Figure 5:

[0056] Mounting brackets 102 are fixedly connected to both sides of the cylinder 101; a reduction motor 202 capable of driving the spindle 201 to rotate is fixedly connected to the mounting bracket 102 on the right side.

[0057] The mounting bracket 102 has screw holes for inserting screws, which facilitates the installation and fixing of the mounting brackets 102 on both sides. When the geared motor 202 is started, it can drive the spindle 201 to rotate, thereby achieving homogenization of the coating and crushing of agglomerated coating.

[0058] A method for preparing a waterborne coating composition using a waterborne coating composition preparation system includes the following steps:

[0059] a: Add the water-based coating composition into the cylinder 101;

[0060] b: The geared motor 202 starts and drives the spindle 201 to rotate. The spindle 201 drives the two collection filter boxes 403 and the two pressure rollers 302 to make circular motion through the ring frame 203, which can perform homogenization treatment on the water-based coating composition.

[0061] c: Both scrapers 404 are in contact with the inner wall of the cylinder 101. During the rotation of the scrapers 404, they can continuously scrape up the clumps of paint deposited on the bottom surface of the cylinder 101 and collect them in the collection filter box 403.

[0062] d: When gear 405 meshes with rack 103, it drives collection filter box 403 to rotate downward, and the clumps of paint collected in collection filter box 403 fall into filter box 104;

[0063] e: When the pressure roller 302 rotates to the top, the round rod 303 enters the slide groove 107. The slide groove 107 presses the round rod 303 to slide downward, thereby driving the pressure roller 302 downward into the filter box 104. The pressure roller 302 slides along the inner wall of the filter box 104 to crush the clumps of paint in the filter box 104. The crushed paint falls back into the cylinder 101.

[0064] f: Repeat the process until there are no lumps of paint in the cylinder 101, then open the valve to discharge the mixed water-based paint composition.
