DETAILED DESCRIPTION

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0024] Specifically, as Figures 1-5 shown, a stirring and mixing device with uniform stirring includes: a mixing cylinder 1, a motor 3 is fixedly connected to the top end of the mixing cylinder 1, a stirring shaft 2 is rotatably connected to the inner wall of the mixing cylinder 1, two stirring rods 21 are fixedly connected to the lower end of the surface of the stirring shaft 2, the top end of the stirring shaft 2 penetrates out of the mixing cylinder 1 and is fixedly connected to the output shaft of the motor 3, and a stirring mechanism 4 is arranged on the surface of the stirring shaft 2; wherein, the stirring mechanism 4 includes a moving ring 41 slidably connected to the surface of the stirring shaft 2, two rotating rods 42 are rotatably connected to the surface of the moving ring 41, two stirring plates 43 are fixedly connected to the surface of the rotating rods 42, one end of each of the two rotating rods 42 penetrates to the inner side of the moving ring 41 and is fixedly connected to a first gear 44, and two racks 45 are fixedly connected to the surface of the stirring shaft 2, and the surface of the first gear 44 is meshed with the surface of the corresponding rack 45.

[0025] An inlet pipe is arranged at the upper end of the surface of the mixing cylinder 1, and an outlet pipe is installed at the bottom end. When it is necessary to stir the coating raw materials, the raw materials, additives, etc. are put into the mixing cylinder 1 through the inlet pipe, and the motor 3 is started to drive the stirring shaft 2 and the stirring rods 21 to rotate for stirring operation. The two stirring rods 21 are symmetrically arranged with respect to the center point of the stirring shaft 2, and the two stirring shafts 2 and the two rotating rods 42 are arranged in a staggered manner. When the stirring shaft 2 rotates, it drives the moving ring 41 to rotate synchronously, so that the two rotating rods 42 drive the stirring plates 43 and the stirring rods 21 to rotate simultaneously to stir the raw materials.

[0026] As Figure 2 、 Figure 3 and Figure 4 shown, the stirring mechanism 4 further includes two second gears 46. The inner wall of one of the second gears 46 is fixedly connected to the upper end of the surface of the stirring shaft 2, a reciprocating lead screw 47 is rotatably connected to the top end of the mixing cylinder 1, the bottom end of the other second gear 46 is fixedly connected to the top end of the reciprocating lead screw 47, the two second gears 46 are meshed with each other, a circular ring 48 is arranged on the surface of the reciprocating lead screw 47, a connecting plate 49 is slidably connected to the upper end of the surface of the moving ring 41, and the other side of the connecting plate 49 is fixedly connected to the surface of the circular ring 48.

[0027] When the stirring shaft 2 rotates, it will drive the two second gears 46 to rotate synchronously, thereby driving the reciprocating screw 47 to rotate. The reciprocating screw is in the form of two threaded grooves with the same pitch and opposite rotation direction, and the two ends are connected by a transition curve. Through the rotation of the reciprocating screw, the side of the spiral groove pushes the moving block placed in the spiral groove to make axial reciprocating motion. Therefore, when the reciprocating screw 47 rotates, it will drive the ring 48 to move back and forth up and down, and under the action of the connecting plate 49, the moving ring 41 will move back and forth up and down synchronously when rotating, thereby driving the toggle plate 43 to move back and forth up and down while rotating. At the same time, when the moving ring 41 drives the rotating rod 42 to move back and forth up and down, under the action of the first gear 44 and the rack 45, the rotating rod 42 will be driven to rotate back and forth with the center of the first gear 44 as the rotation center point, thereby making the toggle plate 43 reciprocate synchronously when it moves up and down during the rotation process.

[0028] like Figure 4 As shown, the upper end of the surface of the stirring shaft 2 is fixedly connected to a limit rod 410, and the inner wall of the moving ring 41 is fixedly connected to a slider 411, and the inner wall of the slider 411 is slidably connected to the surface of the limit rod 410. When the moving ring 41 moves up and down, the inner wall of the slider 411 is driven to move up and down in contact with the surface of the limit rod 410. When the stirring shaft 2 rotates, the limit rod 410 is mobilized to rotate synchronously, and the slider 411 is driven to rotate synchronously, thereby driving the moving ring 41 and the stirring shaft 2 to rotate synchronously.

[0029] like Figure 5 As shown, two sealed bearings 412 are embedded in the inner wall of the moving ring 41, and the surface of the rotating rod 42 is fixedly connected to the inner edge of the corresponding sealed bearing 412. The inner wall of the moving ring 41 is fixedly connected to the outer edge of the sealed bearing 412, and when the rotating rod 42 rotates with the center of the first gear 44 as the rotation center point, the inner edge of the sealed bearing 412 will be driven to rotate synchronously.

[0030] like Figure 4 As shown, the surface of the ring 48 is fixedly connected to the limit plate 414, and the top of the mixing barrel 1 is fixedly connected to the round rod 413, and the top of the round rod 413 passes through the limit plate 414. The inner wall of the limit plate 414 is slidably connected to the surface of the round rod 413, and when the ring 48 moves up and down, it will drive the limit plate 414 to move up and down synchronously.

[0031] like Figure 3 As shown, a cleaning ring 415 is fixedly connected to the bottom end of the moving ring 41, and the shape of the cleaning ring 415 is a flat-topped cone. The inner wall of the cleaning ring 415 fits the surface of the stirring shaft 2. When the moving ring 41 drives the cleaning ring 415 to move downward, the cleaning ring 415 will scrape off the paint on the surface of the stirring shaft 2 below, so that the part of the stirring shaft 2 entering the moving ring 41 remains clean.

[0032] like Figure 5 As shown, the overall shape of the toggle plate 43 is wavy, and the surface of the toggle plate 43 is provided with through holes 416 distributed in equal rows. When the toggle plate 43 is rotating, part of the paint will pass through the through holes 416, and at the same time, due to the specific shape of the toggle plate 43, the raw material can be toggled when the toggle plate 43 rotates back and forth.

[0033] When the utility model is used, when stirring the coating raw materials, the raw materials, additives, etc. are put into the mixing barrel 1 through the feeding pipe, and the motor 3 is started to drive the stirring shaft 2 and the stirring rod 21 to rotate for stirring operation, and the moving ring 41 is driven to rotate synchronously under the action of the limit rod 410 and the slider 411, so that the two rotating rods 42 drive the toggle plate 43 and the stirring rod 21 to rotate simultaneously to stir the raw materials. At this time, part of the coating will pass through the through hole 416. At the same time, the two second gears 46 rotate synchronously and drive the reciprocating screw rod 47 to rotate, thereby driving the ring 48 to reciprocate up and down, and driving the limit plate 414 to move up and down synchronously. When the circular ring 48 moves up and down, the connecting plate 49 makes the moving ring 41 move up and down synchronously while rotating, thereby driving the toggle plate 43 to move up and down while rotating. At the same time, when the moving ring 41 drives the rotating rod 42 to move up and down, under the action of the first gear 44 and the rack 45, the rotating rod 42 is driven to rotate back and forth with the center of the first gear 44 as the rotation center point, thereby making the toggle plate 43 rotate back and forth synchronously while moving up and down during the rotation process, which is conducive to toggling the raw materials above the mixing barrel 1 up and down while continuously stirring the raw materials above.

[0034] It should be noted that the motor 3, sealed bearing 412, etc. in the above description are all relatively mature devices in existing technology applications. The specific models can be selected according to actual needs. At the same time, the motor 3 can be powered by a built-in power supply or by AC power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0035] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
