[0002] Chemical coatings are a general term for liquid or solid materials that can form a solid film with protective, decorative, or special properties when applied to the surface of an object. As one of the main materials for home decoration, coatings account for a large proportion of decoration and renovation. During the use of coatings, it is necessary to mix various coatings and their additives by stirring to improve the performance of the coatings.

[0003] Currently, chemical coatings are often mixed by stirring a stirring shaft to drive a stirring rod. The mixing of a single coating increases the mixing cycle, and it is difficult for coatings to be mixed evenly with each other, which affects the mixing efficiency.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a modified mixer that uses a drive device to move a rack and pinion, enabling a turntable to rotate through meshing teeth, which in turn rotates the mixing tank on the turntable, causing the coating material inside the mixing tank to shake and improving the mixing efficiency.

[0019] The present invention will now be described in detail with reference to the accompanying drawings.

[0020] A modified mixer, such as Figures 1-2 As shown, the system includes a base 1, a turntable 2 rotatably connected to the upper surface of the base 1, two symmetrically distributed support rods 3 fixedly connected to the upper surface of the turntable 2, a mixing tank 4 rotatably connected between the two support rods 3, a stirring rod 5 rotatably connected inside the mixing tank 4, a motor 6 for driving the stirring rod 5 to rotate fixedly installed on the upper surface of the mixing tank 4, stirring blades 7 fixedly connected to the side wall of the stirring rod 5, a feed inlet 8 and a discharge outlet 9 respectively provided on the upper and lower sides of the mixing tank 4, a number of ring-shaped teeth 11 provided on the outer wall of the turntable 2, a rack 10 slidably connected to the upper surface of the base 1, the rack 10 meshing with the teeth 11 on the outer wall of the turntable 2, and a driving device for moving the rack 10 provided on the base 1.

[0021] The driving device includes a groove 13 on the upper surface of the base 1 and a lead screw 12 rotatably connected to the inner wall of the groove 13. A second motor 14 for driving the lead screw 12 to rotate is fixedly installed on the side wall of the base 1. The second motor 14 is a servo motor. One end of the lead screw 12 is connected to the output shaft of the servo motor. A nut seat 15 is sleeved on the lead screw 12. The nut seat 15 is fixedly connected to the bottom wall of the rack 10.

[0022] Two symmetrically distributed fixing plates 16 are fixedly connected to the upper end face of the base 1. The two fixing plates 16 are located on the side of the groove 13 away from the turntable 2. A limiting rod 17 is fixedly connected between the two fixing plates 16. A limiting block 18 is fixedly connected to the side of the rack 10 away from the turntable 2. The limiting block 18 is sleeved on the outer wall of the limiting rod 17. A limiting hole is opened on the limiting block 18 for the limiting rod 17 to pass through. Several arrayed universal balls are provided on the inner wall of the limiting hole. The universal balls are in contact with the surface of the limiting rod 17.

[0023] As the rack 10 reciprocates along with the nut seat 15, the limiting block 18 moves along the limiting rod 17, making the rack 10 more stable during movement. The universal ball rolls against the surface of the limiting rod 17, reducing the friction between the limiting block 18 and the limiting rod 17, and making the movement of the limiting block 18 smoother.

[0024] An extension rod 19 is fixedly connected to one side wall of the mixing tank 4. An abutment rod 20 is fixedly connected to the upper end face of the extension rod 19. A vertical rod 21 is fixedly connected to the upper end face of the base 1. A horizontal rod 22 corresponding to the position of the abutment rod 20 is fixedly connected to the side wall of the vertical rod 21. During the rotation of the mixing tank 4, the abutment rod 20 will abut against the side wall of the horizontal rod 22. A counterweight 23 is fixedly connected to the lower end face of the mixing tank 4.

[0025] Working principle: When the paint enters the mixing tank 4 through the feed port 8 for mixing, the motor 14 drives the lead screw 12 to rotate in both directions. The rotation of the lead screw 12 drives the nut seat 15 to move back and forth along the lead screw 12. The nut seat 15 then drives the rack 10 to move back and forth. Since the retaining teeth 11 on the outer wall of the turntable 2 mesh with the rack 10, the movement of the rack 10 drives the turntable 2 and the mixing tank 4 fixed on the turntable 2 to rotate in both directions, making the mixing of the paint in the mixing tank 4 more efficient.

[0026] Meanwhile, when the mixing drum 4 rotates with the turntable 2 until the contact rod 20 contacts the crossbar 22, the continued rotation of the mixing drum 4 will cause the mixing drum 4 to tilt until it tilts to a certain angle and then the contact rod 20 and the crossbar 22 separate. Without the obstruction of the crossbar 22, the weight of the lower half of the mixing drum 4 is increased by the counterweight 23, making its weight greater than that of the upper half of the mixing drum 4 at the junction of the mixing drum 4 and the support rod 3. This allows the mixing drum 4 to automatically return to a vertical position, so that the mixing drum 4 can also tilt and sway while rotating, which further improves the mixing efficiency of the paint in the mixing drum 4 and effectively shortens the mixing cycle of the paint.

[0027] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
