Problems solved by technology

[0003] 1. The noise generated during belt transmission is large, causing noise pollution to the surrounding environment
[0004] 2. Belts and flexible shafts have a short service life and are often replaced. The steps to replace the flexible shaft are cumbersome and time-consuming
[0005] 3. Large size, high quality, poor portability, and occupying space
[0006] 4. When working, the engraving machine must be hoisted to work, and the bending degree of the flexible shaft is limited
If it is bent too far, it will cause friction with the flexible shaft jacket, resulting in heat generation, shaft breakage, and even burns. The flexible shaft turning angle is not flexible during work.
[0007] 5. Small power, low speed, about 20000r / min, high power consumption, unable to work in an environment without mains power, and limited working area
[0008] 6. Due to the slow speed and low power, the physical strength of the personnel is consumed during work, and the work efficiency is low.

Description

technical field [0001] The invention relates to an engraving machine, in particular to an engraving machine motor cooling device. Background technique [0002] Existing engraving machines, such as jade engraving machines, usually adopt the working method of belt transmission to the flexible shaft and then to the handle, while the cooling of the motor is carried out by the fan installed at the tail of the motor; in addition, the chuck of the engraving machine usually uses The main disadvantages of the three-lobe structure are: [0003] 1. The noise generated during belt transmission is large, causing noise pollution to the surrounding environment. [0004] 2. Belts and flexible shafts have a short lifespan and are often replaced. The procedure for replacing the flexible shaft is cumbersome and time-consuming. [0005] 3. Large size, high quality, poor portability, and occupying space. [0006] 4. When working, the engraving machine must be hoisted to work, and the bending ...
