Description
Technical Field
[0001] This utility model relates to the technical field of non-standard discs on the screw shaft of a mixer, and particularly to a structure for adding non-standard discs to the screw shaft of a mixer. Background Technology
[0002] A mixing machine is a device used to uniformly mix multiple materials. It plays a crucial role in numerous industries. Visually, it has a compact and rational structure, featuring a container to hold the materials. Its working principle involves using specific stirring devices, such as stirring blades, to ensure that materials of different properties come into full contact and mix within the container through various motions, such as rotation and tumbling. In the chemical industry, mixing machines can uniformly mix various chemical raw materials, ensuring the consistency of chemical reactions; in the food processing field, they can uniformly mix various ingredients, guaranteeing the stability of food taste and quality. Furthermore, mixing machines are relatively easy to operate, and operating parameters can be adjusted according to different mixing needs to achieve the ideal mixing effect.
[0003] Mixing machines play a crucial role in many industries. They can uniformly mix various materials, ensuring consistent product quality. In the chemical, pharmaceutical, and food industries, the precise mixing capabilities of mixing machines can improve production efficiency and reduce costs. However, the connection between the auger blades and the drive shaft in mixing machines is often internal. Due to the small contact area of internal connections, the oscillation amplitude of the auger blades during mixing is prone to excessive, causing the fixing bolts to easily become loose or break, thus affecting the service life of the equipment. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides a structure for adding an irregularly shaped disc to the screw shaft of a mixer.
[0005] This utility model is achieved by the following technical solution: a non-standard disk structure is added to the screw shaft of the mixer, including a motor, the output end of the motor is fixedly connected to a reducer, the output end of the reducer is fixedly connected to a transmission shaft, and the end of the transmission shaft is fixedly connected to a drive bevel gear.
[0006] The outer wall of the driving bevel gear meshes with a transmission bevel gear, and the end of the transmission bevel gear away from the driving bevel gear meshes with a driven bevel gear. The end of the driven bevel gear is fixedly connected to a second transmission shaft, and the end of the second transmission shaft is fixedly connected to a transmission disc. The bottom of the transmission disc is fixedly connected to a spiral stirring rod, and the outer wall of the transmission disc is fixedly connected to a fixing bolt.
[0007] Through the above technical solution, the output end of the motor is fixedly connected to a reducer. When the motor is driven by an external 380V AC point, the motor can drive the reducer to rotate. The reducer can reduce the high speed of the motor to a speed suitable for mixing operations, while significantly increasing the output torque. This avoids material splashing or uneven mixing caused by the spiral stirring rod rotating too fast. The output end of the reducer is fixedly connected to a transmission shaft one. When the reducer drives the active bevel gear to rotate through the transmission shaft one, the active bevel gear can drive the transmission bevel gear meshing with the outer wall to rotate. By setting the top of the transmission bevel gear to mesh with the active bevel gear and the end to mesh with the driven bevel gear, the kinetic energy of the active bevel gear can be transmitted through the transmission bevel gear, thereby causing the driven bevel gear meshing with its end to rotate. The driven bevel gear is fixedly connected to a transmission shaft two, and the transmission shaft two is fixedly connected to a transmission disc. When the driven bevel gear rotates, it can drive the transmission shaft two and the transmission disc to rotate synchronously. The transmission disc is fixedly connected to the spiral stirring rod by fixing bolts, thereby increasing the strength of the connection between the transmission disc and the spiral stirring rod, and thus increasing the service life of the equipment.
[0008] As a further improvement to the above scheme, the number of transmission bevel gears is set to two, and the two transmission bevel gears are symmetrically distributed on the left and right sides with the driving bevel gear as the center.
[0009] Through the above technical solution, the number of transmission bevel gears is two and they are symmetrically distributed with the driving bevel gear as the center. Each of the two transmission bevel gears is meshed with a driven bevel gear, and each of the two driven bevel gears is connected to a spiral stirring rod. By setting two spiral stirring rods inside the main body of the mixer, the mixing degree during the mixing process can be increased by the two spiral stirring rods, ensuring uniform mixing of materials throughout the entire area.
[0010] As a further improvement to the above solution, a bearing is fixedly connected to the middle of the drive shaft.
[0011] Through the above technical solution, the transmission shaft is fixedly connected to the bearing, the inner wall of the bearing is fixedly connected to the transmission shaft, and the outer wall is fixedly connected to the upper cover plate. In this way, the frictional resistance between the transmission shaft and the main body of the mixer can be reduced by the bearing, thereby increasing the smoothness of the transmission shaft during rotation.
[0012] As a further improvement to the above solution, an upper cover plate is fixedly connected to the outer wall of the bearing, a feed port is fixedly connected to the upper surface of the upper cover plate, and a protective shell is fixedly connected to the inner wall of the upper cover plate.
[0013] Through the above technical solution, the bearing is fixedly connected to the upper cover plate, and the upper cover plate is fixedly connected to the protective shell. By setting the protective shell on the outer wall of the gear, the gear can be protected by the protective shell, thereby avoiding foreign objects from affecting the meshing transmission between the gears during the stirring process, and thus increasing the stability of the equipment during the stirring process.
[0014] As a further improvement to the above solution, the number of feed inlets is set to two, and the two feed inlets are symmetrically distributed on the left and right sides with the cover plate as the center.
[0015] With the above technical solution, there are two feed inlets that are fixedly connected to the upper cover plate. By setting two symmetrical feed inlets on the outer wall of the upper cover plate, different materials can be fed in separately, thereby further increasing the mixing efficiency of the equipment.
[0016] As a further improvement to the above solution, the lower surface of the upper cover plate is fixedly connected to the main body of the mixer, the outer wall of the main body of the mixer is fixedly connected to the fixed base, and the bottom of the fixed base is fixedly connected to the main support.
[0017] Through the above technical solution, the upper cover plate is fixedly connected to the main body of the mixer, and the main body of the mixer is fixedly connected to the fixed base. By setting the fixed base on the outer wall of the main body of the mixer and connecting it with the main body support, the connection between the main body of the mixer and the main body support can be increased by the fixed base.
[0018] As a further improvement to the above solution, the number of fixed bases is set to four, and the four fixed bases are symmetrically distributed on the left and right sides with the main body of the mixer as the center.
[0019] With the above technical solution, the number of fixed bases is one active bevel gear, and each fixed base is connected to a main support, so that the main support can provide support for the equipment, thereby increasing the stability of the overall equipment.
[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0021] This invention features a motor output end fixedly connected to a reducer. When an external 380V AC drive motor rotates the reducer, the reducer can lower the motor's high speed to a suitable speed for mixing operations, while significantly increasing the output torque. The reducer's output end is fixedly connected to a transmission shaft. When the reducer drives the active bevel gear to rotate via the transmission shaft, the active bevel gear drives the transmission bevel gear meshing with the outer wall to rotate. By setting the top of the transmission bevel gear to mesh with the active bevel gear and the end to mesh with the driven bevel gear, the kinetic energy of the active bevel gear can be transmitted, causing the driven bevel gear to rotate. The driven bevel gear is fixedly connected to a transmission shaft, which is in turn fixedly connected to a transmission disc. The transmission disc is fixedly connected to a spiral stirring rod via bolts, increasing the strength of the connection between the transmission disc and the spiral stirring rod, thus extending the equipment's service life. By installing two spiral stirring rods inside the mixer body, the mixing degree during the mixing process is increased, ensuring uniform mixing of materials throughout the entire process.
[0022] This utility model increases the smoothness of the transmission shaft's rotation by fixing the inner wall of the bearing to the inner wall and the upper cover plate to the outer wall. By setting a protective shell on the outer wall of the gear, the gear can be protected, thus preventing foreign objects from affecting the meshing transmission and increasing the stability of the mixing process. Furthermore, by setting two feed inlets, different materials can be fed in separately, improving the mixing efficiency of the equipment. Attached Figure Description
