Description

Technical Field

[0001] This utility model relates to the technical field of mixing equipment, and in particular to a power unit for a mixer. Background Technology

[0002] A food mixer is a common food processing machine, often used for kneading dough, as well as mixing crumbly, powdery, and liquid foods.

[0003] Conventionally, a mixer mainly consists of two parts: a power unit and a mixer. The power unit drives the mixer to rotate, and the mixer can mix the food being processed. Existing power units are equipped with a motor and a gearbox. The gearbox can reduce the speed of the motor, converting the high speed of the motor into the low speed required by the mixing shaft.

[0004] However, in order to meet the speed reduction requirements of multi-stage gear transmission, traditional gearboxes have a large number of drive shafts and gears, resulting in a large size. In addition, the core components such as gear sets and drive shafts are completely enclosed inside the gearbox, resulting in a small assembly space, which makes assembly difficult and time-consuming for workers.

The belt drive assembly includes a first pulley, a second pulley, and a drive belt. The first pulley is coaxially connected to the output shaft, the second pulley is coaxially connected to the first drive shaft, and the drive belt is drivingly connected to the first pulley and the second pulley.
