Description

Technical Field

[0001] This application relates to the field of mixer technology, and in particular to stirring mixers. Background Technology

[0002] Most widely used mixers on the market today rely on traditional motor-driven shaft rotation to mix materials. While these devices are simple in structure and inexpensive, they are inefficient in handling high-viscosity materials or applications requiring extremely high uniformity. With the acceleration of industrialization, the demands for mixing quality and production efficiency are increasing, and traditional mixers are gradually failing to meet the high standards of modern production.

[0003] To improve mixing efficiency, existing mixers often incorporate multiple stirring rods. However, the mixture tends to settle to the bottom during mixing, and the multiple stirring rods make it difficult to agitate the mixture at the bottom, thus affecting mixing efficiency. Utility Model Content

[0004] The purpose of this invention is to solve or at least alleviate the problems existing in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mixing device, comprising a mixing tank and a top cover assembly installed on the mixing tank, wherein a mixing assembly is installed on the inner wall of the bottom of the mixing tank, the top cover assembly includes a top cover snapped onto the mixing tank, and three equally spaced circularly distributed stirring rods are rotatably connected to the outer wall of the bottom of the top cover, and stirring rods are rotatably connected to the outer wall of the bottom of the top cover, and the stirring rods are connected to the mixing assembly, a feed pipe is fixedly connected to the outer wall of the top of the top cover, and a discharge pipe is fixedly connected to the outer wall of the bottom of the mixing tank.

[0006] By adopting the above structure, the mixing tank facilitates the mixing of materials. The removable top cover assembly on the mixing tank facilitates the cleaning of the inside of the mixing tank. The cooperation between stirring rod one and stirring rod two on the top cover stirs the materials in the mixing tank. The stirring component in the mixing tank facilitates the stirring of the materials at the bottom of the mixing tank, effectively preventing the materials from settling at the bottom of the mixing tank.

[0007] Optionally, the bottom outer wall of the stirring rod 2 is provided with a rib groove, and the inner walls on both sides of the rib groove are provided with limit grooves.

[0008] By adopting the above structure, the connection of the auxiliary stirring component is facilitated through the fit between the groove and the limiting groove at the bottom of the stirring rod 2.

[0009] Optionally, the stirring assembly includes a mounting bracket fixedly connected to the inner wall of the mixing tank, and the top outer wall of the mounting bracket has a circular opening, the inner wall of which is rotatably connected to a stirring rod.

[0011] Optionally, a prism is fixedly connected to the top outer wall of the stirring rod, and the specifications of the prism and the prism groove are matched.

[0012] By adopting the above structure, the prism on the stirring rod three can be easily connected to the groove.

[0013] Optionally, the prism has an internal mounting cavity, and the inner walls on both sides of the mounting cavity have openings. The inner walls of the two openings are slidably connected to limit blocks, and the specifications of the limit blocks match the specifications of the limit grooves.

[0014] By adopting the above structure, the installation cavity facilitates the sliding installation of the limiting block. When the limiting block extends, it is easy to insert it into the limiting groove, thereby facilitating the fixing of the prism in the groove.

[0015] Optionally, the same bidirectional screw is rotatably connected to the inner walls of both sides of the mounting cavity, and two symmetrically arranged threaded sleeves are screwed onto the outer wall of the bidirectional screw. Two connecting plates are rotatably connected to the outer walls of the two threaded sleeves. Two symmetrically arranged sliding plates are slidably connected to the inner wall of the mounting cavity. The two limiting blocks are respectively fixedly connected to the two sliding plates, and one end of each of the four connecting plates is rotatably connected to the two sliding plates.

[0016] By adopting the above structure, the two threaded sleeves can be directly driven to move towards or away from each other when the bidirectional screw rotates. When the two threaded sleeves move towards each other, the two sliding plates can be directly pushed to move away from each other through the connecting plate.

[0017] Optionally, a reduction motor is fixedly connected inside the stirring rod three, and the output shaft of the reduction motor is fixedly connected to a bidirectional screw.

[0018] By adopting the above structure, the geared motor can be used to directly drive the bidirectional screw to rotate, thereby facilitating the direct adjustment of the positions of the two limit blocks.

[0019] Optionally, three equally spaced circularly distributed gear 1 are rotatably connected to the inner wall of the bottom of the top cover, and one end of the drive shaft of each of the three gear 1 is fixedly connected to one of the three stirring rods. A gear 2 is rotatably connected to the center of the inner wall of the bottom of the top cover, and one end of the drive shaft of the gear 2 is fixedly connected to the stirring rod 2. A servo motor is fixedly connected to the outer wall of the top of the top cover, and the drive shaft of the servo motor is fixedly connected to the gear 2. All three gear 1 are meshed with gear 2.

[0020] By adopting the above structure, the rotation of gear two is driven by a servo motor, and the rotation of gear two directly drives the rotation of three gears one, thereby facilitating the synchronous rotation of auxiliary stirring rod one and stirring rod two to stir the materials in the mixer.

[0021] In summary, the beneficial effects of this application are as follows: 1. In this invention, by setting a stirring component at the bottom of the mixing tank, and by cooperating with the stirring rod in the top cover component, the stirring component can be directly driven to stir the material at the bottom of the mixing tank, thereby avoiding the problem of material settling at the bottom of the mixing tank and making it difficult to mix.

[0022] 2. This application sets a prism on the stirring assembly, and two adjustable limiting blocks in the prism facilitate fixing the prism in the groove of the stirring rod. The rotation of the bidirectional screw in the mounting cavity directly drives the two threaded sleeves to drive the connecting plate, and then drives the two limiting blocks to move, which facilitates the disassembly of the top cover to clean the stirring rod.

[0034] Reference Figure 3-4Three equally spaced circular gears 12 are rotatably connected to the inner wall of the bottom of the top cover 5. One end of the drive shaft of each gear 12 is fixedly connected to one of the three stirring rods 8. When the gears 12 rotate, they directly drive the stirring rods 8 to rotate, thus stirring the material in the mixing tank 1. A gear 2 13 is rotatably connected to the center of the inner wall of the bottom of the top cover 5. One end of the drive shaft of the gear 2 13 is fixedly connected to a stirring rod 2 9.

The servo motor 6 drives gear 2 13 to rotate, and the rotation of gear 2 13 directly drives the three gears 1 12 to rotate, thus facilitating the synchronous rotation of stirring rod 1 8 and stirring rod 2 9 to stir the material in the mixer.

[0035] The implementation principle of this application is as follows: When it is necessary to mix materials, the materials are first injected into the mixing tank 1 through the feed pipe 7, and then the servo motor 6 is started. The start of the servo motor 6 directly drives the gear 13 to rotate. When the gear 13 rotates, it directly drives the three gears 12 to rotate, thereby facilitating the rotation of the stirring rod 8 and the stirring rod 9 to stir the materials. When it is necessary to clean the mixing tank 1, the reduction motor 23 is started first. The reduction motor 23 drives the bidirectional screw 18 to rotate. When the bidirectional screw 18 rotates, it drives the two threaded sleeves 19 to move apart, directly engaging with the connecting plate 22, pulling the two sliding plates 20 to move towards each other. When the sliding plates 20 move towards each other, it directly causes the two limiting blocks 21 to move towards each other, thereby facilitating the removal of the limiting blocks 21 from the limiting groove 11, thus facilitating the removal of the top cover 5 for cleaning the stirring rods.
