Description

Technical Field

[0001] This utility model relates to the field of material mixing equipment technology, and in particular to a mixing device that facilitates extrusion feeding. Background Technology

[0002] In modern industrial production, there is a widespread demand for the mixing and extrusion of various materials. Industries such as plastics, rubber, and chemical raw materials require the uniform mixing of different materials in a certain proportion before extrusion molding to produce products with specific performance and quality requirements. During the process of materials entering the mixing device, hopper blockage is a common and serious problem that affects production efficiency. This is especially true for materials with high viscosity, high moisture content, uneven particle size, or containing easily entangled fibers, which are more prone to accumulation and blockage in the hopper. In many production processes, such as plastic extrusion molding to produce plastic products and rubber mixing to manufacture tires, uneven mixing of materials can lead to defects in physical properties, chemical properties, and appearance quality of the products, such as insufficient strength, inconsistent color, and uneven surface. Traditional unidirectional stirring methods often have dead zones, making it impossible for materials to be fully agitated and mixed in the mixing device, and it is difficult to ensure the uniformity of material mixing. The emergence of bidirectional stirring technology has led us to propose a mixing device that facilitates extrusion and discharge to solve this problem. Utility Model Content

[0003] The purpose of this invention is to provide a mixing device that facilitates extrusion and feeding, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A mixing device for easy extrusion and feeding includes: a mixing tank, the mixing tank having an internal stirring assembly, the stirring assembly including: a first bevel gear, a second bevel gear, and a third bevel gear, the second and third bevel gears meshing with the first bevel gear; a second stirring shaft fixedly installed inside the third bevel gear, a first stirring shaft rotatably installed inside the second stirring shaft, the first stirring shaft being fixedly connected to the second bevel gear; multiple sets of connecting rings fixedly installed on the outer sides of both the first and second stirring shafts, multiple sets of second stirring rods fixedly installed on the outer sides of the multiple sets of connecting rings; a feeding pipe fixedly installed at the bottom of the mixing tank, a housing fixedly installed at the bottom of the feeding pipe, an auger inside the housing, an extrusion pipe fixedly installed at the bottom of the housing; a feeding hopper fixedly installed at the top of the mixing tank, the feeding hopper having an anti-clogging assembly inside, the anti-clogging assembly including: a rotating shaft, multiple sets of collars fixedly installed on the outer side of the rotating shaft, multiple sets of first stirring rods fixedly installed on the outer side of the multiple sets of collars.

[0006] Preferably, a protective shell is fixedly installed on the top of the mixing tank. The first bevel gear, the second bevel gear, and the third bevel gear are all disposed inside the protective shell. The first stirring shaft is rotatably installed on the inner wall of the top of the protective shell. The second stirring shaft is rotatably connected to the mixing tank and rotatably penetrates into the interior of the protective shell. A connecting shaft is fixedly installed on one side of the first bevel gear. The connecting shaft is rotatably installed inside one side of the protective shell. A first motor is fixedly installed on one side of the protective shell. The output shaft of the first motor is fixedly connected to the connecting shaft.

[0007] Preferably, the rotating shaft is rotatably mounted on the inner walls of both sides of the feed hopper, and a second motor is fixedly mounted on one side of the feed hopper, with the output shaft of the second motor fixedly connected to the rotating shaft.

[0008] Preferably, the auger is rotatably mounted on the inner wall of one side of the housing, and a motor is fixedly mounted on one side of the housing, with the output shaft of the motor fixedly connected to the auger.

[0009] Preferably, a heating plate is provided inside the mixing tank, and the heating plate is fixedly installed between the outer wall and the inner wall of the mixing tank.

[0010] Preferably, three sets of support frames and two sets of support plates are fixedly installed at the bottom of the mixing tank and the shell, respectively, and the three sets of support frames are distributed in a ring at equal intervals at the bottom of the mixing tank.

[0011] In this utility model, a mixing device for easy extrusion feeding is provided, comprising a feeding hopper, an anti-clogging component, a second motor, a housing, an auger, and a third motor. By driving the second motor, the rotating shaft drives multiple sets of collars to rotate, which in turn drives multiple sets of stirring rods on the outer side to rotate. By driving the third motor, the third motor drives the auger to rotate, so that the material mixed by the auger plates is extruded sequentially from left to right and finally flows out from the extrusion pipe, preventing the feeding hopper from being blocked due to material accumulation. Under the action of the stirring rods, the material is continuously turned and stirred, keeping it in a loose state, thereby enabling continuous and stable delivery into the mixing tank, ensuring the continuity of material supply, and avoiding the normal operation of the entire extrusion feeding process due to interruption of feeding. It can push the mixed material from left to right with a relatively stable speed and force, making the material extrusion process more uniform and avoiding problems such as irregular shape and unstable size of the extrudate caused by sudden changes in feeding speed or uneven force.

[0012] In this invention, a mixing device for easy extrusion and feeding is provided with a stirring assembly. A drive motor drives a connecting shaft to rotate a bevel gear, which in turn drives bevel gears two and three, which in turn drives a stirring shaft two. This causes bevel gear two to rotate within the stirring shaft two, and the connecting ring and stirring rod two on the outer sides of the stirring shafts one and two to rotate in opposite directions, achieving bidirectional stirring. This bidirectional stirring ensures that all corners of the material are covered, avoiding dead zones and allowing for more thorough agitation and mixing within the device. This significantly improves the uniformity of the mixture, ensuring product quality stability. Compared to traditional unidirectional stirring, bidirectional stirring allows for more stirring actions within the same timeframe, thus accelerating the mixing speed, reducing mixing time, and improving production efficiency.
