[0001] The present application relates to the technical field of water-based paint preparation, and in particular to a preparation system and process for corrosion-resistant water-based paint. Background Art

[0002] Water-based paint is a paint that uses water as a diluent and does not contain organic solvents. It does not contain benzene, toluene, xylene, formaldehyde, free TDI and other toxic heavy metals. It is non-toxic and has no irritating odor, is harmless to the human body, and does not pollute the environment. The paint film is plump, crystal clear, flexible, and is water-resistant, wear-resistant, aging-resistant, yellowing-resistant, fast-drying, and easy to use.

DETAILED DESCRIPTION

[0023] The technical solution of the present application will be described clearly and completely below in conjunction with the accompanying drawings.

Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0024] The present application embodiment discloses a system for preparing a corrosion-resistant water-based paint. Figure 1 The preparation system includes a stirring device for stirring and mixing the raw materials of the water-based paint. The stirring device includes a bracket 100, a stirring barrel 200, a stirring paddle 300 and a cleaning component 400.

A feed inlet 230 is provided on the side of the mixing barrel 200 away from the ground, and a cover body for opening and closing the feed inlet is rotatably connected to the feed inlet 230. A discharge pipe 210 is connected to the side of the mixing barrel 200 close to the ground, and a valve 211 for adjusting the material flux on the discharge pipe 210 is provided on the discharge pipe 210.

[0026] Reference Figure 1 and Figure 2The stirring paddle 300 includes a central rod 310 and a stirring blade 320. The central rod 310 includes a rotating sub-rod 311 and a plurality of limiting sleeves 312. The plurality of limiting sleeves 312 are sequentially arranged along the length direction of the rotating sub-rod 311, and the limiting sleeves 312 are sleeved on the outside of the rotating sub-rod 311. Adjacent limiting sleeves 312 are rotationally connected, and the limiting sleeves 312 located away from the bottom of the mixing barrel 200 are rotationally connected to the mixing barrel 200. A support rod is fixedly connected to the bottom of the mixing barrel 200, and the limiting sleeves 312 close to the bottom of the mixing barrel 200 are rotationally connected to the support rod. One end of the rotating sub-rod 311 away from the bottom of the mixing barrel 200 extends beyond the mixing barrel 200 and is coaxially fixedly connected to the output shaft of a driving motor 220. The body of the driving motor 220 is fixedly connected to the outer wall of the mixing barrel 200.

[0027] There are multiple stirring blades 320. In this embodiment, there are eight stirring blades 320. The eight stirring blades 320 are arranged in groups of two. Four limiting sleeves 312 are provided, and one group of stirring blades 320 corresponds to one limiting sleeve 312. Four groups of stirring blades 320 are arranged in sequence along the length direction of the central rod 310, and one end of the stirring blades 320 is fixedly connected to a rotating shaft 321, the rotating shaft 321 is rotatably connected to the corresponding limiting sleeve 312, and the rotating shaft 321 extends between the limiting sleeve 312 and the rotating sub-rod 311, and the other ends of the eight stirring blades 320 extend in a direction away from the central rod 310, so that the stirring blades 320 can stir and mix the materials in the mixing barrel 200. The rotating sub-rod 311 is fixedly connected with a rotating block 313 and a limit block 314 which are in contact with the rotating shaft 321. The limit block 314 and the rotating block 313 are respectively arranged on both sides of the corresponding rotating shaft 321, so that when the part of the rotating shaft 321 extending between the rotating sub-rod 311 and the limit sleeve 312 is in contact with the rotating block 313 or the limit block 314, the rotating sub-rod 311 can drive the limit sleeve 312 and the stirring blade 320 to rotate, so as to stir the raw materials in the stirring barrel 200.

[0028] In order to prevent the adjacent stirring blades 320 from interfering with the axial disturbance of the raw material, a plurality of rotating blocks 313 are provided, and the rotating blocks 313 correspond to the stirring blades 320 one by one. Along the length direction of the rotating sub-rod 311, the plurality of rotating blocks 313 corresponding to the stirring blades 320 on the same side are arranged in a spiral shape, so that along the length direction of the rotating sub-rod 311, multiple groups of stirring blades 320 are arranged in a spiral shape, thereby reducing the axial disturbance between adjacent groups of stirring blades 320. The plurality of limiting blocks 314 corresponding to the stirring blades 320 on the same side are fixedly connected, so that after the rotating shaft 321 of the stirring blade 320 conflicts with the corresponding limiting blocks 314, the stirring blades 320 are located on the same vertical plane.

[0029] A rotating assembly 500 for driving the stirring blades 320 of the same group to rotate is provided in the mixing barrel 200. The rotating assembly 500 includes a rotating bevel gear ring 510 and a rotating wheel 520. The rotating bevel gear ring 510 is coaxially fixedly connected to the rotating sub-rod 311. Two rotating wheels 520 are provided, and the rotating wheels 520 correspond to the rotating shafts 321 one by one. The rotating wheels 520 are coaxially fixedly connected to the corresponding rotating shafts 321. A plurality of teeth 521 are fixedly connected to the rotating wheel 520, and the teeth 521 mesh with the rotating bevel gear ring 510.

[0030] When the driving motor 220 drives the rotating sub-rod 311 to rotate, that is, the rotating bevel gear ring 510 rotates, the teeth 521 on the rotating wheel 520 mesh with the rotating bevel gear ring 510, so that the rotating bevel gear ring 510 drives the rotating wheel 520 to rotate, so that the rotating wheel 520 can drive the stirring blade 320 to rotate a certain angle, so that the stirring blade 320 can better stir the raw materials in the mixing barrel 200. When the rotating sub-rod 311 drives the rotating block 313 to rotate until the rotating block 313 conflicts with the rotating shaft 321, the rotating sub-rod 311 can drive the limiting sleeve 312 to rotate, so that the stirring blade 320 can stir the raw materials in the mixing barrel 200.

[0031] The staff can adjust the gear ratio of the rotating bevel gear ring 510 and the teeth 521 of the rotating wheel 520 according to the position of the rotating block 313 corresponding to the rotating shaft 321, and adjust the rotation angle of the stirring blade 320, so that the stirring device can be suitable for stirring water-based paints of different viscosities, thereby further improving the use range of the stirring device.

[0032] Reference Figure 3 and Figure 4The cleaning assembly 400 is used to clean the stirring device. The cleaning assembly 400 includes a cleaning frame 410, a cleaning pipe 420 and a liquid storage cylinder 430. The cleaning frame 410 can be moved in a direction close to or away from the bottom of the stirring barrel 200. A cavity connected to the cleaning pipe 420 is opened on the cleaning frame 410. The cleaning frame 410 is fixedly connected with a plurality of cleaning nozzles 421 connected to the cavity. The plurality of cleaning nozzles 421 are divided into two groups, one group of cleaning nozzles 421 is arranged toward the stirring blade 320 so that the cleaning nozzles 421 clean the stirring blade 320, and the other group of cleaning nozzles 421 is arranged away from the center line of the stirring barrel 200, so that the cleaning nozzles 421 can clean the side walls of the stirring barrel 200 and the stirring paddle 300. One end of the cleaning tube 420 away from the cleaning rack 410 is connected to the liquid storage cylinder 430, and the liquid storage cylinder 430 is rotatably connected to the mixing barrel 200, and the rotation axis of the liquid storage cylinder 430 and the mixing barrel 200 is colinearly arranged with the rotation axis of the limiting sleeve 312, and the end of the liquid storage cylinder 430 away from the mixing barrel 200 is rotatably connected to the cover 431, and the liquid storage cylinder 430 is connected to a connecting pipe 432 for connecting to a source of cleaning liquid, and the connecting pipe 432 is connected to the cover 431.

[0033] Reference Figure 5 and Figure 6 In order to prevent the cleaning liquid in the cleaning rack 410 from falling into the paint due to vibration when the stirring device is running, an adjusting piston 433 is provided in the liquid storage cylinder 430. The adjusting piston 433 is sealed and slidably connected to the liquid storage cylinder 430, and the adjusting piston 433 and the liquid storage cylinder 430 can rotate relative to each other. A connecting rod 240 is fixedly connected to the stirring barrel 200, and a hole is provided on the adjusting piston 433 for the connecting rod 240 to pass through, so as to realize the sliding connection between the connecting rod 240 and the adjusting piston 433. A connecting ring 315 is rotatably connected to the limiting sleeve 312, and the adjusting piston 433 is threadedly connected to the limiting sleeve 312.

[0034] The connecting ring 315 is provided with a plurality of sliding grooves 3151 perpendicular to the axial direction of the limiting sleeve 312, and the plurality of sliding grooves 3151 are evenly arranged along the circumference of the connecting ring 315. A sliding block 3152 is provided in the sliding groove 3151, and the sliding block 3152 is slidably connected to the side wall of the sliding groove 3151. The limiting sleeve 312 is provided with a groove 3121 engaged with the sliding block 3152, and the portion engaged with the sliding block 3152 and the groove 3121 is set to be hemispherical. A connecting spring 3153 is provided in the sliding groove 3151, and one end of the connecting spring 3153 is fixedly connected to the sliding block 3152, and the other end is fixedly connected to the bottom of the sliding groove 3151. Under the elastic force of the connecting spring 3153, the sliding block 3152 is engaged with the groove 3121.

[0035] The regulating piston 433 includes a sealing portion 4331 and a sliding portion 4332. The sealing portion 4331 is located in the liquid storage barrel 430, and both sides of the sealing portion 4331 are in contact with the side walls of the liquid storage barrel 430. A one-way valve is provided on the sealing portion 4331 so that the cleaning liquid can only flow from the side of the sealing portion 4331 away from the bottom of the liquid storage barrel 430 to the side close to the bottom of the liquid storage barrel 430. The sliding portion 4332 is integrally formed with the sealing portion 4331, and one end of the sliding portion 4332 away from the sealing portion 4331 extends beyond the liquid storage barrel 430 and is threadedly connected to the connecting ring 315. A positioning block 434 is fixedly connected to the side wall of the liquid storage cylinder 430. There are multiple positioning blocks 434, which are arranged in two groups. The two groups of positioning blocks 434 are arranged on both sides of the sealing part 4331, and one group of positioning blocks 434 located on the side of the sealing part 4331 close to the bottom of the liquid storage cylinder 430 is spaced apart from the bottom of the liquid storage cylinder 430.

[0036] When the limiting sleeve 312 rotates forwardly under the action of the rotating sub-rod 311, the regulating piston 433 is not easy to rotate under the action of the connecting rod 240, and the sliding block 3152 is engaged with the groove 3121, so that the limiting sleeve 312 can drive the connecting ring 315 to rotate, and then the regulating piston 433 moves in a direction away from the bottom of the liquid storage cylinder 430 under the action of the connecting ring 315, thereby increasing the pressure in the liquid storage cylinder 430 and causing the residual cleaning liquid in the cleaning frame 410 to be sucked back into the liquid storage cylinder 43 0, thereby achieving the purpose of preventing the cleaning liquid in the cleaning rack 410 from dripping into the paint. When the sealing portion 4331 moves to the side away from the bottom of the liquid storage cylinder 430 and contacts the positioning block 434, the sealing portion 4331 is difficult to continue to move. At this time, the connecting spring 3153 is compressed, so that the sliding block 3152 slides out of the groove 3121, and the limiting sleeve 312 cannot continue to drive the connecting ring 315 to rotate, so that the connecting ring 315 is difficult to continue to drive the adjusting piston 433 to move. When the limiting sleeve 312 rotates in the opposite direction under the action of the rotating sub-rod 311, the regulating piston 433 is not easy to rotate under the action of the connecting rod 240, and the sliding block 3152 is engaged with the groove 3121, so that the limiting sleeve 312 can drive the connecting ring 315 to rotate, and then the regulating piston 433 moves in the direction away from the bottom of the liquid storage cylinder 430 under the action of the connecting ring 315. When the sealing portion 4331 moves to the side close to the bottom of the liquid storage cylinder 430 and contacts the positioning block 434, the sealing portion 4331 is not easy to continue to move. At this time, the connecting spring 3153 is compressed, so that the sliding block 3152 slides out of the groove 3121, and the limiting sleeve 312 can no longer drive the connecting ring 315 to rotate, so that the connecting ring 315 is not easy to continue to drive the regulating piston 433 to move.

[0037] Replay Figure 3 and Figure 4, a moving assembly 600 for driving the cleaning rack 410 to move is provided in the mixing barrel 200, and the moving assembly 600 includes a connecting frame 610, a moving lead screw 620 and a moving rope 630. The connecting frame 610 is rotatably connected to the limiting sleeve 312, the moving lead screw 620 is a reciprocating lead screw, and is rotatably connected to the connecting frame 610, and a pulley 622 is rotatably connected to the slider 621 of the moving lead screw 620. One end of the moving rope 630 is fixedly connected to a side of the connecting frame 610 close to the side wall of the mixing barrel 200, and the other end passes through the connecting frame 610 and is fixedly connected to the cleaning rack 410 after passing through the pulley 622; in other embodiments, the staff can set the number of pulleys 622 according to the length of the mixing barrel 200, so that the cleaning assembly 400 can be suitable for cleaning mixing barrels 200 of different sizes.

[0038] The connecting frame 610 is provided with a driving assembly 700 for driving the movable lead screw 620 to rotate. The driving assembly 700 includes a driving bevel gear 710, a transmission bevel gear 720, a driving ratchet 730 and a driving pawl 740. The driving bevel gear 710 is fixedly connected to the mixing barrel 200, the transmission bevel gear 720 is meshed with the driving bevel gear 710, and is coaxially fixedly connected to the movable lead screw 620. The driving ratchet 730 is coaxially fixedly connected to the limiting sleeve 312, the driving pawl 740 is rotationally connected to the connecting frame 610, and is meshed with the driving ratchet 730. In order to maintain the meshing state of the driving pawl 740 and the driving ratchet 730, a torsion spring is connected to the driving pawl 740, one end of the torsion spring is connected to the driving pawl 740, and the other end is connected to the connecting frame 610. Under the elastic force of the torsion spring, the driving pawl 740 is meshed with the driving ratchet 730.

[0039] In order to better clean the paint on the inner wall of the mixing barrel 200, a scraper 322 is rotatably connected to the side of the mixing blade 320 away from the center rod 310. The scraper 322 is rotatably connected to the mixing blade 320, and the scraper 322 and the mixing blade 320 are set at an angle. An adjusting torsion spring for adjusting the rotation angle of the scraper 322 is provided on the scraper 322. One end of the adjusting torsion spring is fixedly connected to the scraper 322, and the other end is fixedly connected to the mixing blade 320. Under the action of the adjusting torsion spring, when the plane of the mixing blade 320 is perpendicular to the horizontal plane, the scraper 322 contacts the inner wall of the mixing barrel 200, and the scraper 322 is tilted. Along the direction of reverse rotation of the mixing blade 320, the side of the scraper 322 away from the ground is located at the front side, so that the scraper 322 can play a role of pushing the material on the inner wall of the mixing barrel 200 downward.

[0040] Based on the above preparation system, the present application also proposes a preparation process of a corrosion-resistant water-based paint, which uses the above preparation system to prepare the corrosion-resistant water-based paint.

[0041] The implementation principle of a corrosion-resistant water-based paint preparation system according to an embodiment of the present application is as follows: after the staff injects the raw materials into the mixing barrel 200, the driving motor 220 is started to make the driving motor 220 rotate in the forward direction and drive the rotating sub-rod 311 to rotate. At this time, the limiting sleeve 312 does not rotate, so that the rotating sub-rod 311 drives the rotating bevel gear ring 510 to rotate the rotating wheel 520, that is, the stirring blade 320 rotates. When the rotating sub-rod 311 drives the rotating rotating wheel 520 to a certain angle, the rotating block 313 on the rotating sub-rod 311 conflicts with the rotating shaft 321, so that the rotating sub-rod 311 can drive the limiting sleeve 312 to rotate, so that the stirring blade 320 stirs the raw materials in the mixing barrel 200; at this time, the driving pawl 740 continuously rotates back and forth on the driving ratchet 730, so that the driving ratchet 730 is not easy to drive the driving pawl 740 and rotate the connecting frame 610.

[0042] When the staff needs to clean the stirring device, the driving motor 220 is controlled to rotate in the opposite direction so that the driving motor 220 drives the rotating sub-rod 311 to rotate. At this time, the limiting sleeve 312 does not rotate, so that the rotating sub-rod 311 drives the rotating bevel gear ring 510 to make the rotating wheel 520 rotate in the opposite direction, that is, the stirring blade 320 rotates and resets. When the rotating sub-rod 311 rotates until the rotating shaft 321 conflicts with the corresponding limiting block 314, the rotating sub-rod 311 drives the limiting sleeve 312 to rotate, that is, the stirring blade 320 rotates and drives the scraper 322 to clean the side wall of the stirring barrel 200.

[0043] Due to the meshing of the driving ratchet 730 and the driving pawl 740, the limiting sleeve 312 can drive the connecting frame 610 to rotate during rotation, and the driving bevel gear 710 is meshed with the transmission bevel gear 720. Since the driving bevel gear 710 is not easy to rotate, the transmission bevel gear 720 rotates and drives the moving screw 620 to rotate, that is, the moving slider 621 moves back and forth, so that the moving rope 630 drives the connecting frame 610 to move closer to or away from the bottom of the mixing barrel 200.

[0044] Water from a water source is injected into the liquid storage cylinder 430 , then passes through the cleaning pipe 420 and the cleaning rack 410 , and finally is sprayed out from the cleaning nozzle 421 to clean the paint on the stirring blade 320 and the side wall of the stirring barrel 200 .

[0045] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
