Structure and common problems of small belt machine
The small belt machine is composed of a belt, a belt housing containing the belt, a motor, a motor housing containing the motor, a handle, a driving wheel, a driven wheel, and a transmission device connecting the motor and the driving wheel. The small belt machine has become the main equipment for grinding processing, and as the application of the small belt machine becomes more and more widely used, people's understanding of the small belt machine becomes more and more in-depth. But there are still many people who do not know much about it. Next, let's get to know this device together!

Small belt machine structure
Â
The small belt machine includes an abrasive belt, an abrasive belt housing accommodating the abrasive belt, a motor, a motor housing accommodating the motor, a handle, a driving wheel, a driven wheel, and a transmission device connecting the motor and the driving wheel, and the motor housing The unit is integrally connected with the handle to form a unit body, and a connecting device connects the unit body to the belt shell.

Common problems of small belt machine
Â
1. Vibration problem: Some abrasive belt machines hang the abrasive belt. After starting the machine, the machine vibrates greatly. If it is not fixed, it will run around . What is the reason? In fact, it is mainly because the balance of the rotating wheel is not good. The rotating wheel has a rubber wheel, a guide wheel, and a motor pulley. One of the three rotating wheels has poor accuracy, poor balance, and poor machine shake! Another reason is that the matching clearance of the parts of the support wheel is too large, which causes relative movement between the parts and vibration. Furthermore, the motor is not fixed well, and it also generates vibration.
2. Noise problem: The noise is mainly due to insufficient rigidity of the base and supporting parts, and the gap between the matching parts is too large (some factories have poor processing equipment and are backward, plus poor quality awareness, the manufactured parts are very bad, and there are almost no tolerances for matching Requirements!), Choose low-quality bearings, abrasive cloth belt speed is too fast and other reasons.
3. Life problems: Some abrasive belt machines break down in a short time , because the adjustment part uses gray cast iron, does not use 45 # carbon steel precision casting, or does not undergo heat treatment, bearing quality is poor, lubrication is not good, the main shaft No modulation heat treatment is performed, or the hardness of the treatment is too low or too high (too low to wear, too high to break), and the quality of the motor is not good.
4. Problems of use: The design of the machine's size and structure is critical. Better structure and scientific size are the key to the efficiency of the polishing workers.
Due to the continuous development of sand belt machine technology, the role of sand belt machine polishing in the metal processing industry has become irreplaceable. With advanced belt polishing equipment, metal processing tasks such as surface polishing, round polishing, dressing polishing and grinding, radius polishing, chamfering and deburring can be successfully completed. Using a modular design, this can increase the flexibility of the equipment and reduce costs. Industrial batch processing companies have high requirements for the flexibility of the equipment used.
The above is the structure of the small belt machine and common problems introduced for everyone. The small belt machine adopts a modular technical solution, which can reduce production costs and save storage space in the production workshop. If you only need to add the components required for each processing step to the basic equipment, the return on investment of the equipment is also very high.
