[0002] Water-based acrylic resin refers to acrylic resin that can be dissolved, emulsified or dispersed in water. The biggest difference between water-based acrylic resin and traditional solvent-based acrylic resin is that water-based acrylic resin rarely uses or does not use organic solvents. Therefore, it has the advantages of reducing VOC emissions, being green and environmentally friendly, safe to use, saving resources and energy, etc. Therefore, it has become the main direction of the current development of acrylic resin coatings. When workers produce and process water-based acrylic resin, they need to use a reactor to stir and mix the raw materials.

[0003] However, there are some problems with the existing technology: although the existing reactor can basically stir and mix the water-based acrylic resin raw materials and other additives to cause a reaction, in actual use, due to the high viscosity and poor fluidity of the resin, the existing reactor only stirs by simply rotating the stirring rod, which makes it difficult for the resin raw materials and other additives at different depths inside the reactor to fully contact, react and mix. It takes a long time to stir to achieve a good mixing effect, and the production and processing efficiency is low. Therefore, we propose a water-based acrylic resin reactor. Summary of the Invention

[0024] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0025] like Figures 1 to 5 As shown, an embodiment of the present invention provides a water-based acrylic resin reactor, including a reactor 1, a feed port 2 is provided at the top of the reactor 1, a discharge port 3 is provided at the bottom of the reactor 1, a stirring mechanism is provided inside the reactor 1, vertical rods 4 are fixedly installed on both sides of the top of the inner wall of the reactor 1, a rotary block 5 is hinged on the vertical rod 4, a toggle plate 6 is fixedly connected to the rotary block 5, and the rotary block 5 is also connected to the reactor 1 through a transmission assembly.

[0026] Furthermore, the stirring mechanism includes a drive motor 7, which is fixedly mounted on the top of the reactor 1. The output shaft of the drive motor 7 is fixedly sleeved with a rotating shaft 8, the bottom end of the rotating shaft 8 extends into the interior of the reactor 1, the outer surface of the rotating shaft 8 is fixedly mounted with a stirring rod 9, and the top of the outer surface of the rotating shaft 8 is fixedly sleeved with a first bevel gear 10.

[0027] By starting the driving motor 7, the rotating shaft 8 can drive the stirring rod 9 to rotate, thereby stirring the water-based acrylic resin raw material and other additives to improve the mixing degree.

[0028] Furthermore, the transmission assembly includes a rotating shaft 11, which is rotatably connected to the top of the reactor 1. One end of the rotating shaft 11 is fixedly connected to the second bevel gear 12, which is meshed with the first bevel gear 10. The other end of the rotating shaft 11 is fixedly connected to the disc 13. Both sides of the top of the reactor 1 are movably connected with movable rods 14, and the rotary block 5 is movably sleeved on the movable rod 14. The top of the movable rod 14 is fixedly connected to a square frame 15, and a first round block 16 located inside the square frame 15 is fixedly mounted on the disc 13.

[0029] When the drive motor 7 is running and the rotating shaft 8 drives the first bevel gear 10 to rotate, the second bevel gear 12 can drive the rotating shaft 11 and the disk 13 to rotate, so that the disk 13 can drive the first round block 16 to rotate. Due to the rotation of the first round block 16, the inner wall of the square frame 15 will be squeezed, so that the movable rod 14 can reciprocate up and down.

[0030] Furthermore, an inner groove 17 is formed on the rotating block 5 , and a second round block 18 is slidably connected to the interior of the inner groove 17 , and the second round block 18 is fixedly connected to the movable rod 14 .

[0031] When the movable rod 14 reciprocates up and down, it can drive the second round block 18 to move, so that the rotary block 5 can drive the toggle plate 6 to swing up and down, and then the water-based acrylic resin raw materials at different depths can be mixed with other additives, thereby further improving the stirring and mixing effect.

[0032] Furthermore, a cross bar 19 is fixedly connected to the bottom of the rotating shaft 8 , and scrapers 20 are fixedly installed on both sides of the top of the cross bar 19 , and the scrapers 20 are attached to the inner wall of the reactor 1 .

[0033] When the shaft 8 rotates, the scraper 20 can be driven to rotate through the cross bar 19, so that the material adhering to the inner wall of the reactor 1 can be scraped off, avoiding the material adhering to the inner wall of the reactor 1 for a long time and being difficult to participate in stirring, thereby affecting the mixing reaction effect.

[0034] Furthermore, an auger rod 21 is fixedly installed in the middle of the bottom end of the cross bar 19 , and the bottom of the auger rod 21 extends to the inside of the discharge port 3 .

[0035] When unloading the material, the rotating shaft 8 can continue to drive the auger rod 21 to rotate, so that the material can be squeezed downward from the discharge port 3, thereby improving the efficiency of collecting the material.

[0036] Furthermore, a blade 22 is fixedly mounted on the outer surface of the rotating shaft 8 , and the length of the blade 22 is the same as that of the stirring rod 9 .

[0037] Through the design of the blade 22, when the shaft 8 drives the blade 22 to rotate, the blade 22 can cut the raw materials, reduce the volume of the raw materials, and facilitate better fusion of the raw materials.

[0038] Furthermore, a through hole 23 is formed on the toggle plate 6 , and a cover plate 24 is hinged on the top of the toggle plate 6 , and the width of the cover plate 24 is greater than the width of the through hole 23 .

[0039] When the toggle plate 6 swings upward, the cover plate 24 is affected by the resistance of the material and covers the through hole 23, thereby improving the effect of conveying the material upward. When the toggle plate 6 swings downward to return to its original position, the cover plate 24 is affected by the resistance of the material and rotates to release the blockage of the through hole 23, thereby preventing the material from being conveyed to the lower part of the reactor 1 again.

[0040] Furthermore, a water pipe 25 is fixedly installed on the top of the inner wall of the reactor 1 , and a nozzle 26 is fixedly connected to the water pipe 25 .

[0041] After the materials are collected, the staff can introduce water into the water pipe 25 so that the water is sprayed from the nozzle 26 to wash the inner wall of the reactor 1, which makes it convenient for the staff to clean the interior of the reactor 1.

[0042] Furthermore, a heat-insulating sleeve 27 is fixedly sleeved on the outer surface of the reactor 1 , and the bottom of the inner wall of the reactor 1 is arc-shaped.

[0043] The working principle and use process of this utility model:

[0044] After the staff adds the water-based acrylic resin raw material and other additives into the reactor 1, the driving motor 7 is started to make the rotating shaft 8 drive the stirring rod 9 to stir the raw materials. Since the resin has high viscosity and poor fluidity, the transmission component can be used to make the toggle plate 6 to toggle the raw materials to improve fluidity and enhance the stirring and mixing effect. Specifically, when the rotating shaft 8 drives the first bevel gear 10 to rotate, the second bevel gear 12 can drive the rotating shaft 11 and the disc 13 to rotate, so that the disc 13 can drive the first round block 16 to rotate. Due to the rotation of the first round block 16, the inner wall of the frame 15 will be squeezed, so that the movable rod 14 can reciprocate up and down. When the movable rod 14 reciprocates up and down, it can drive the second round block 18 to move, so that the rotary block 5 can drive the toggle plate 6 to swing up and down, and then the water-based acrylic resin raw materials at different depths and other additives can be mixed, thereby further improving the stirring and mixing effect. When unloading, the rotating shaft 8 can continue to drive the auger rod 21 to rotate, so that the material can be squeezed downward from the discharge port 3 to improve the efficiency of collecting materials. After the material is collected, the staff can introduce water into the water pipe 25, so that the water source is sprayed from the nozzle 26 to flush the inner wall of the reactor 1, which is convenient for the staff to clean the inside of the reactor 1.

[0045] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
