[0070] Depend on Figure 1-Figure 5Provided is a preparation device for epoxy resin floor paint, comprising a mixing tank 1, a frame 2 is arranged outside the mixing tank 1, moving wheels 3 are installed at the four corners of the lower end of the frame 2, a discharge pipe 4 is connected to the middle part of the lower end of the mixing tank 1, a top cover 5 is arranged at the upper end of the mixing tank 1, a mixing assembly 6 is arranged at the upper end of the top cover 5, the lower part of the mixing assembly 6 is located inside the mixing tank 1, both ends of the top cover 5 are rotatably connected to a flap 8 through a hinge 7, U-shaped seats 9 are distributed circumferentially on the outer wall of the upper part of the mixing tank 1, a locking screw 11 is rotatably connected to the inside of the U-shaped seat 9 through a pin shaft 10, and the locking screw 11 is movably engaged with the flap 8;

[0071] The mixing assembly 6 includes a motor 601 installed in the middle of the upper end of the top cover 5, the output end of the motor 601 is connected to a rotating shaft 602, the upper part of the rotating shaft 602 is fixedly connected to a driving gear 603, a shell 604 is provided outside the driving gear 603, the shell 604 is connected to the top cover 5, both sides of the lower end of the shell 604 are rotatably connected to rotating rods 605, the outside of the rotating rod 605 is connected to a stirring rod 606, the upper ends of the rotating rods 605 on both sides extend to the inside of the shell 604 and are connected to driven gears 607, and the driven gears 607 on both sides are meshed and connected with the driving gear 603;

[0072] The outside of the rotating shaft 602 is connected with a spiral blade 608, and the outside of the spiral blade 608 is sleeved with a cylinder 609, which is rotatably sleeved on the outside of the rotating shaft 602, and the upper part of the outer wall of the cylinder 609 is connected with a fixing ring 610, and the fixing ring 610 is rotatably connected to the shell 604, and both sides of the lower part of the cylinder 609 are provided with a feed port 611, and both sides of the upper part of the cylinder 609 are provided with a discharge port 612;

[0073] A driven bevel gear 613 is fixedly connected to the upper end of the cylinder 609, and the driven bevel gear 613 is sleeved on the outside of the rotating shaft 602. Support rods 614 are connected to both sides of the inside of the housing 604. One end of the two support rods 614 is rotatably connected to a transmission bevel gear 615. The two transmission bevel gears 615 are meshed with the driven bevel gear 613. A driving bevel gear 616 is fixedly sleeved on the upper side of the outer side of the rotating shaft 602, and the driving bevel gear 616 is meshed with the two transmission bevel gears 615.

[0074] The outer wall of the cylinder 609 is cross-symmetrically connected with a fixing seat 617, one end of the fixing seat 617 is rotatably connected with a cross bar 618, the outside of the cross bar 618 is connected with a stirring blade 619, one end of the cross bar 618 is connected with a transmission gear 620, the inner wall of the mixing tank 1 is connected with a gear ring 621, the transmission gear 620 is meshed with the gear ring 621, and the upper end of the gear ring 621 is arranged in an inclined shape;

[0075] The lower part of the outer wall of the cylinder 609 is connected with a scraper 622, and the scraper 622 is in contact with the lower part of the inner wall of the mixing tank 1;

[0076] A mounting frame 12 is connected to one side of the outer wall of the frame 2, and a control box 13 is installed at one end of the mounting frame 12;

[0077] When the materials are mixed, the motor 601 drives the rotating shaft 602 to rotate, and under the drive of the rotating shaft 602, the driving gear 603 is meshed with the driven gears 607 on both sides, so that the driven gears 607 on both sides drive the rotating rod 605 to rotate, and the rotating rod 605 drives the stirring rod 606 to rotate, so as to stir the materials on the upper side of the mixing tank 1;

[0078] On the other hand, when the rotating shaft 602 rotates, it drives the spiral blade 608 to rotate. Under the action of the rotation of the spiral blade 608, the material entering the cylinder 609 from the feed port 611 can be spirally transported upward, and then discharged from the cylinder 609 from the discharge port 612. By transporting the material upward from the cylinder 609 from the bottom to the top, the material at the bottom of the mixing tank 1 can be transported to the upper position, so that the lower material in the mixing tank 1 is exchanged with the upper material, avoiding uneven stirring during mixing and stirring, and increasing the mobility of the material.

[0079] In addition, when the rotating shaft 602 rotates, the active bevel gear 616 on its upper part rotates, and then the active bevel gear 616 meshes with the transmission bevel gear 615 for transmission, and the transmission bevel gear 615 meshes with the driven bevel gear 613 for transmission. Since the driven bevel gear 613 is fixedly connected to the cylinder 609, the cylinder 609 is rotatably connected to the housing 604 under the action of the fixing ring 610. In this way, when the rotating shaft 602 rotates, the cylinder 609 is driven to rotate. When the cylinder 609 rotates, it can drive the external cross bar 618 to rotate in the circumferential direction. The cross bar 618 meshes with the lower end of the gear ring 621 under the action of the transmission gear 620. At this time, the cross bar 618 itself rotates, so that the cross bar 618 drives the stirring blade 619 to rotate. The cross bar 618 rotates in the horizontal direction, and the stirring blade 619 rotates in the longitudinal direction, so that the materials in the lower part of the mixing tank 1 can be stirred in two directions. Compared with the existing single-direction stirring action, the mixing and stirring effect is effectively improved, and the uniformity of the materials is ensured.

[0080] When the cylinder 609 rotates, the scraper 622 located at the lower part thereof rotates synchronously, and the scraper 622 scrapes the materials at the bottom of the mixing tank 1 to effectively prevent the materials from settling.
