DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-4A raw material mixing device for preparing acrylic board, comprising a mixer table 1, a reactor 4 is arranged on one side of the mixer table 1, a driving shaft 21 is rotatably installed inside the reactor 4, a stirring impeller 11 and a stirring rod 5 are respectively installed on the driving shaft 21, a wing plate 8 is rotatably installed on one side of the stirring rod 5 through a damping shaft 12, a cleaning strip 91 is installed on one side of the wing plate 8 through a fixing rod 9, and spray nozzles 10 are installed on the upper and lower parts of one side of the wing plate 8;

[0022] Furthermore, a protective shell 7 is installed on one side of the upper part of the stirring rod 5, and a micro motor 71 is installed in the protective shell 7. The output end of the micro motor 71 is driven and connected to a driving gear 13, and one side of the driving gear 13 is connected to a driven gear 14 through gear meshing. The driven gear 14 is installed on the upper part of the damping shaft 12.

[0023] Furthermore, the inner bottom wall of the reactor 4 is provided with a discharge hole 6, through which materials or waste water can be discharged.

[0024] Furthermore, a plurality of rotation grooves 51 are opened on one side of the stirring rod 5, and a damping shaft 12 is rotatably installed in the rotation groove 51, and a plurality of rotation blocks 81 are respectively fixedly connected to the damping shaft 12. Through the setting of the damping shaft 12 and the rotation block 81, the rotation stability of the wing plate 8 can be effectively guaranteed.

[0025] Furthermore, a wing plate 8 is installed in the rotating groove 51 for limited rotation via a rotating block 81 , and the wing plate 8 is matched with a mounting groove 52 opened on the inner side of the stirring rod 5 .

[0026] Furthermore, a stirring motor 2 is installed on one side of the stirring machine table 1, and a feed cover 3 is installed at the bottom of the stirring motor 2, the bottom of the feed cover 3 is connected to the reactor 4, and the output end of the stirring motor 2 is drivingly connected to the drive shaft 21, and the other end of the drive shaft 21 passes through the feed cover 3 and extends into the reactor 4, wherein "C"-shaped stirring rods 5 are arranged on both sides of the middle of the drive shaft 21, and a stirring impeller 11 is installed in the middle of the bottom end of the drive shaft 21.

[0027] Furthermore, the spray nozzle 10 is connected to the connecting pipe 101 , and the spray effect of the spray nozzle 10 is achieved by connecting the external water pump connecting pipe 101 .

[0028] In this embodiment, the stirring motor 2 drives the driving shaft 21 to drive the stirring rod 5 and the stirring impeller 11 to rotate, and stir the reaction materials inside the reactor 4. During the stirring process, the stirring rod 5 can effectively stir the materials in the upper, middle and lower parts of the reactor 4, and the stirring effect can be further improved by setting the bottom stirring impeller 11, thereby enhancing the temperature stability and mixing uniformity during the reaction process.

[0029] After the reaction is completed, some materials will adhere to the inner wall of the reactor 4 due to the high temperature. At this time, the driving gear 13 is driven by the micro motor 71, and the driving gear 13 is driven by the driven gear 14 on the other side through gear meshing, thereby realizing the driving transmission effect of the damping shaft 12. When the damping shaft 12 rotates, the wing plate 8 is driven to rotate outward through the rotating block 81, and stops after rotating to a certain angle. At this time, the stirring motor 2 drives the unfolded stirring rod 5 to rotate again. During the rotation, the spray nozzle 10 sprays clean water onto the reactor wall and under the continuous rubbing action of the cleaning strip 91 on the reactor wall, the attached materials on the reactor wall are removed, which effectively improves the cleaning effect. Compared with traditional manual cleaning, this mechanism can complete the cleaning effect of the inner wall of the reactor 4 without disassembling the device, which not only saves time and effort but also has high cleaning efficiency.

[0030] In actual use, the damping shaft 12 cooperates with the rotating mechanism of the rotating block 81 and the damping force and deceleration effect during the rotation of the damping shaft 12 can effectively improve the rotation stability of the wing plate 8.

[0031] It is worth noting that the input end of the spray nozzle 10 is connected to the connecting pipe 101, which is installed inside the wing plate 8, penetrates into the stirring rod 5 and is connected to an external water pump.

[0032] In the utility model, the arrangement of the stirring rod 5 and the stirring impeller 11 can effectively improve the stirring performance of the material, increase the stirring effect, and ensure the temperature stability and uniformity of the material during the reaction process. At the same time, after the reaction is completed, the wing plate 8 is unfolded and the inner wall of the reactor 4 is swept. In conjunction with the spray nozzle 10, the cleaning strip 91 and other components, the cleaning efficiency is effectively improved, avoiding the situation where the material adheres to the reactor wall, thereby improving the mixing quality.
