In order to quickly adjust the width of the belt conveyor, the following mechanisms or methods can be used: 
1、 Width adjustment mechanism 
A belt conveyor with adjustable width includes a fixed frame, a movable frame, a width adjustment mechanism, and a transmission mechanism symmetrically installed on the fixed frame and the movable frame. Among them, the width adjustment mechanism is a key part, which usually consists of an active adjustment seat, a passive adjustment seat, and two parallel guide rails set between the fixed frame and the movable frame. The movable frame is connected to two guide rails through sliding blocks to achieve width adjustment. The active adjustment seat is equipped with a width adjustment motor, which can drive the movable frame to slide on the guide rail, thereby changing the width of the belt conveyor. 
2、 Replace conveyor belts of different specifications 
Adjust the bandwidth size as needed and directly replace it with a suitable conveyor belt specification. For example, choosing a wider conveyor belt increases bandwidth, or choosing a narrower conveyor belt decreases bandwidth. Although this method is simple and direct, it requires the preparation of different specifications of conveyor belts in advance, and the replacement process may require downtime, which affects production efficiency. 
3、 Adjust the spacing between the rollers or the position of the support frame 
By increasing or decreasing the spacing between the rollers, or adjusting the position of the support frame, the working length of the conveyor belt can be changed, thereby adjusting the width of the belt. Smaller drum spacing or internal movement of the support frame will shorten the working length of the conveyor belt, thereby increasing the bandwidth; However, larger drum spacing or outward movement of the support frame will increase the working length of the conveyor belt and reduce its width. This method requires adjusting the mechanical structure, which is relatively complex, but can achieve width adjustment without replacing the conveyor belt. 
4、 Adjust the tensioning device 
Adjusting the tension device of the conveyor belt can change the tension level of the conveyor belt, thereby affecting the bandwidth to a certain extent. Relaxing the tensioning device appropriately can increase the flexibility of the bandwidth, but attention should be paid to avoiding belt slippage; The tightening device can maintain the stability of the conveyor belt, but may reduce the available range of bandwidth. This method is usually used as an auxiliary tool. 
5、 Adopting a modular design with adjustable width 
Some advanced belt conveyors adopt a modular design with adjustable width, allowing users to quickly adjust the width of the conveyor according to their actual needs. This design typically includes detachable or sliding side panels, adjustment mechanisms, and other components that can be easily adjusted in width through simple operations. This method has the advantages of high flexibility and fast adjustment speed, but may require additional investment costs. 
In summary, the use of width adjustment mechanisms, replacement of different specifications of conveyor belts, adjustment of drum spacing or support frame position, adjustment of tensioning devices, and modular design with adjustable width can all achieve rapid adjustment of belt conveyor width. The specific choice of method depends on factors such as the actual application scenario, cost budget, and adjustment frequency.
