Description

Technical Field

[0001] This utility model relates to the field of food processing machine technology, and more specifically to a noise reduction structure for a food processing machine based on the disassembly of transmission and positioning functions. Background Technology

[0002] A food processor is a kitchen appliance that breaks down the cell walls of food through high-speed rotating blades. Its core function is to release deep nutrients (such as dietary fiber and phytochemicals) from food and improve digestibility and absorption. It is widely used to make juice, soy milk, rice paste, sauces, etc. Traditional food processors are noisy when running at high speeds, especially when driven by high-power motors. The cup connector needs to bear the dual functions of power transmission (connecting the motor shaft and the blade shaft) and positioning (fixing the cup body and the base), resulting in a complex structure and high assembly precision requirements. After long-term use, the connector is prone to wear or deformation, which can reduce the coaxiality of the transmission shaft and the blade shaft, causing mechanical vibration and noise. Patent publication number CN118892277A, patent name is a blade assembly that can move up and down. The proposed stirring structure uses a connector to connect the motor shaft and the blade shaft. After long-term use, it produces noise.

[0003] Traditional integrated connectors in food processors are sensitive to processing errors, making it difficult to guarantee the stability of power transmission. Furthermore, integrated connectors are prone to wear, and the drive shaft and blade shaft are susceptible to vibration, resulting in noise. Secondly, simply adding sound insulation materials such as rubber pads can only partially suppress noise and cannot solve the root cause of vibration. Utility Model Content

[0005] This utility model provides the following technical solution: a noise reduction structure for a food processing machine based on the disassembly of transmission and positioning functions, including a device base and a positioning component. The positioning component is fixedly connected to the top center of the device base, and an organic body is fixedly connected to the outside of the positioning component. The positioning component includes a heating plate, a stirring blade shaft is movably sleeved inside the heating plate, a stirring blade is fixedly connected to the top outside of the stirring blade shaft, an upper connector is movably connected to the bottom outside of the stirring blade shaft, a bottom extension structure of the stirring blade shaft, a soft rubber head is movably connected to the bottom of the upper connector, and a lower connector is movably connected to the bottom of the soft rubber head. The device base includes a motor shaft, a connecting hole is provided at the top center of the motor shaft, and the top connecting hole of the motor shaft is compatible with the bottom extension structure of the stirring blade shaft.

[0006] Furthermore, the device base includes a base shell, a mounting bracket is fixedly connected to the top of the inner side of the base shell, a connecting seat is fixedly connected to the top of the mounting bracket, and a support frame is fixedly connected to the bottom outer side of the mounting bracket.

The device base 1 includes a motor shaft 106, and a connecting hole is provided in the middle of the top of the motor shaft 106. The top connecting hole of the motor shaft 106 is compatible with the bottom extension structure of the stirring blade shaft 202. The extension structure of the stirring blade shaft 202 is embedded in the connecting hole of the motor shaft 106. Through the self-centering compensation mechanism, the assembly coaxiality deviation is effectively corrected.

[0021] By setting a soft rubber head 205 between the upper connector 204 and the lower connector 206, vibration energy can be effectively absorbed, operating noise can be reduced, and direct contact between metal parts can be avoided, reducing the risk of wear. The upper connector 204, soft rubber head 205 and lower connector 206 form an independent positioning structure, replacing the positioning function of the traditional connector. The connection part between the upper connector 204, soft rubber head 205 and lower connector 206 adopts a rounded corner structure, which facilitates the alignment of holes, improves the convenience of operation and improves the coaxiality of operation to achieve the noise reduction effect.

[0022] In a preferred embodiment, the device base 1 includes a base housing 101, a mounting bracket 102 is fixedly connected to the top of the inner side of the base housing 101, a connecting seat 103 is fixedly connected to the top of the mounting bracket 102, and a support bracket 104 is fixedly connected to the bottom outer side of the mounting bracket 102.

[0023] In a preferred embodiment, a drive motor 105 is fixedly connected to the center of the support frame 104, and a motor shaft 106 is fixedly connected to the top of the drive motor 105. The top of the outer side of the motor shaft 106 is threaded, and the outer thread of the motor shaft 106 is compatible with the lower connector 206. The motor shaft 106 and the lower connector 206 are fixedly connected by the thread. A cooling fan 107 is fixedly connected to the bottom of the drive motor 105. An intermediate drive shaft is formed by the upper connector 204, the soft rubber head 205, and the lower connector 206. A split drive shaft design is formed by the motor shaft 106, the intermediate drive shaft, and the stirring blade shaft 202, which achieves structural optimization. The positioning component 2 uses a high-precision bearing to fit with the motor bearing, which effectively corrects the assembly coaxiality deviation and allows the drive shaft to self-adjust within the micrometer deviation range. This helps to reduce eccentric vibration caused by assembly errors, reduce the impact of assembly errors on coaxiality, reduce mechanical vibration from the source, achieve noise reduction, and significantly extend the product's service life.

[0026] The working principle of this utility model:

[0027] By fixing the motor shaft 106 to the top of the drive motor 105 and the cooling fan 107 to the bottom, synchronous heat dissipation during operation is facilitated. The mounting bracket 102 and support bracket 104 make the installation and removal of the drive motor 105 more convenient. The soft rubber head 205 between the upper connector 204 and the lower connector 206 effectively absorbs vibration energy, reduces operating noise, and avoids direct contact between metal parts, reducing the risk of wear. The upper connector 204, soft rubber head 205, and lower connector 206 form an independent positioning structure, replacing the positioning function of traditional connectors. Furthermore, the rounded corners of the connection between the upper connector 204, soft rubber head 205, and lower connector 206 facilitate hole alignment and improve operation. To improve convenience and enhance operational coaxiality for noise reduction, the extended structure of the stirring blade shaft 202 is embedded in the connecting hole of the motor shaft 106. Through a self-aligning compensation mechanism, assembly coaxiality deviations are effectively corrected. An intermediate drive shaft is formed by the upper connector 204, the soft rubber head 205, and the lower connector 206. The motor shaft 106, the intermediate drive shaft, and the stirring blade shaft 202 form a split drive shaft design, achieving structural optimization. The positioning component 2 uses high-precision bearings that fit into the motor bearings, effectively correcting assembly coaxiality deviations. This allows the drive shaft to self-adjust within a micrometer-level deviation range, which helps reduce eccentric vibrations caused by assembly errors, reduces the impact of assembly errors on coaxiality, reduces mechanical vibration at the source, achieves noise reduction, and significantly extends product lifespan.
