Description

Technical Field

[0001] The present invention relates to the technical field of meat grinders, and in particular to a noise-reducing meat grinder. Background Art

[0002] Meat grinders are widely used in home kitchens, restaurants, and food processing companies. They use a motor to drive a high-speed rotating auger, chopping and grinding ingredients, significantly improving food processing efficiency. However, in actual use, existing meat grinders are often noisy, seriously affecting the user experience and the environment. Firstly, conventional meat grinders often use standard motors. During operation, friction between components such as the rotor and bearings, as well as electromagnetic forces, generates significant operating noise. Furthermore, the transmission structure between the motor and auger is not well designed. For example, a rotating rod supported by a single bearing is prone to vibration due to uneven force during high-speed rotation. This vibration is transmitted through the mechanical structure to the entire machine, further amplifying the noise. Furthermore, the overall sealing of existing meat grinders is poor, with a gap between the mixing chamber and the cover, which cannot effectively block the transmission of noise. Furthermore, due to the lack of specialized noise reduction and heat dissipation designs, the heat generated by the motor over long periods of operation is difficult to dissipate. This not only affects the motor's performance and service life, but can also cause component deformation due to overheating, exacerbating noise and vibration. These noise problems will interfere with daily life in home use scenarios and affect the business environment in commercial places. Therefore, there is an urgent need for a new meat grinder that can effectively reduce noise. Summary of the Invention

[0003] In view of the above problems, the present invention proposes a noise-reducing meat grinder.

[0004] The specific technical solutions are as follows:

[0005] A noise-reducing meat grinder comprises a base, a main unit and a cover. The cover is located above the main unit and is provided with a feeding port. A material guide plate and a protective frame are provided at the feeding port. The main unit comprises a stirring chamber, a motor chamber and a heat dissipation chamber. The stirring chamber is used in conjunction with the motor chamber. The heat dissipation chamber is located below the motor chamber and is fixed to the base.

[0006] A reamer mounting frame is provided in the mixing bin, a reamer and a fixing rod are provided between the reamer mounting frames, and a discharge port is provided below the mixing bin.

[0007] A bearing seat and a noise reduction motor are provided in the motor compartment. The noise reduction motor is connected to the bearing seat through a rotating rod. There are two bearing seats. A rotating bearing is provided on the bearing seat. The rotating bearing includes an active bearing and a driven bearing.

[0008] One end of the rotating rod is connected to the noise reduction motor, and the other end passes through the active bearing on the bearing seat and is used in conjunction with the reamer mounting frame and the reamer in the mixing bin.

[0009] The driven bearing is used in conjunction with the reamer mounting frame and the reamer in the mixing bin by rotating the auxiliary rod.

[0012] The present invention applies for a noise reduction meat grinder, which includes a base, a main unit and a cover. The cover is located above the main unit, and is provided with a feeding port. The feeding port is provided with a guide plate and a protective frame. The main unit includes a mixing chamber, a motor chamber and a heat dissipation chamber. The mixing chamber and the motor chamber are used in conjunction with each other. The heat dissipation chamber is located below the motor chamber and is fixed to the base. A noise reduction motor is used to reduce operating noise from the sound source. Two bearing seats are provided in the motor chamber, and are equipped with an active bearing and a driven bearing.
