A better action is to identify the reason why the belt is mistracking and correct that issue. If adjustments need to be made, they should be made to low-tension rollers. The amount of friction between the low-tension rollers is identified by the drive pulley and the belt. The head pulley and tail pulley should be aligned and square.

اقرأ أكثرTension in a conveyor belt is fundamental to its very operation in terms of supporting the load between rollers and enabling the drive to impart motion to it. For a conveyor on the verge of slipping, there is a direct ratio between T1, the traction force imparted to the Conveyor and T2, the Take-Up Tension, of a Conveyor Belt. This ratio is of the

اقرأ أكثرThe standard speed for most unit handling conveyors is 65 FPM (feet per minute) which works out to the average speed a person walks when carrying a 50-pound box. This pace is ideal for many—but not all—order picking and assembly operations. There are always situations where transport through an area, into a process, or toward a packing operation can be accelerated.
اقرأ أكثرA conveyor is - essentially - a constant torque load. What that really means is that both power and speed move together - when one goes up, the other does as well. A relatively simple means to get to the higher speed is to change gear ratio - but that may mean slightly higher gear losses and less actual power transmission to the belt.
