Conveyor belt conveyor belt is the key to the conveying system equipment, the safe and stable operation of directly affect the production operation. Conveyor belt running deviation is the most common fault of belt conveyer, the timely and accurate processing is the guarantee of the safe and stable operation. Running deviation phenomenon and for many reasons, different running deviation phenomenon and reasons of the different adjustment methods, can effectively solve the problem. This article is based on many years practice, from the user perspective, by using the theory of mechanics analysis and explain the reason for such failures and solutions.
　　Conveyor belt running deviation often check the parts and processing methods are:
　　1, check the rollers lateral axis and longitudinal center line of belt conveyor is not coincidence degree. Value is more than 3 mm, if you don't contact ratio should be used on either side of the roller set long form hole on the installation and adjustment. Specific methods is on what side of conveyor belt deviation, supporting roller group which side of the annular belt along the direction forward, backwards, or the other side.
　　2, check the head and tail frame installation deviation values of the two surfaces of the bearing. If deviation is greater than 1 mm in the plane of the two, the response to two plane adjustment in the same plane. Cylinder head adjustment method is: if the conveyor belt to the right side of the roller running deviation, the roller on the right side of the bearing should move forward or on the left side of the bearing pedestal ward; If conveyor belt to the cylinder on the left side of the wandering, the roller bearing should move forward or right on the left side of the bearing seat. The tail roller adjustment method is contrary to the head roller.
　　3, check the location of the material on the conveyor belt. Material on the conveyor belt transect is not centered, will lead to the conveyor belt running deviation.
　　If the material slants to the right, the belt running deviation, and to the left and vice versa. When in use, should as far as possible let material center. To reduce or avoid this kind of conveyor belt running deviation can increase the baffle plate, change the direction of the material and location.
　　
　　Actually conveyor belt running deviation for many reasons, this requires us to continuously review practice in the middle of the production. In the process of production, we should keep on the conveyor belt repair, why it would make the conveyor belt better work.
　　4, the axis of the cylinder head or tail redirection roller driving drum and the center line of the conveyor is not vertical, conveyor belt roller of the head or the tail redirection roller in wandering. Platen deflection, firmness, on either side of the conveyor belt in the roller along the width direction of the traction Fq also inconsistent, as increasing or decreasing trend, so you can make the belt attached to a decline in the direction of movement Fy, led to the conveyor belt to the loose side wandering, known as the "running loose not tight.Its adjustment method is: for cylinder head such as conveyor belt to the right side of the roller running deviation, the bearing should move forward, on the right side of the conveyor belt to the drum of the left side of the wandering, is on the left side of the bearing should be move forward, the corresponding also can be on the left side of the bearing seat back or right side of the bearing seat. The tail roller adjustment method is contrary to the head roller. After repeated adjustment until the position of the conveyor belt to the ideal. Best before adjusting drive or redirection roller installed its position accurately.
　　5, roller surface processing error, size, or uneven wear caused diameter sizes to larger diameter on one side of the conveyor belt will be wandering. The so-called "running big not small. Conveyor belt traction Fq produced a big lateral movement of component Fy to diameter, the component under the action of Fy, conveyor belt offset. For this case, the solution is to clean up roller surface sticky material and processing error and uneven wear has to be replaced down reprocessed plastic bags.
　　6, transfer point blanking malposition of conveyor belt running deviation, transfer point material blanking position of corrugated conveyor belt conveyor belt running deviation has very big effect, especially in the article on the conveyor and conveyor in this section in the horizontal plane projection into vertical impact is bigger. Usually should consider transfer points up and down relative height of the two belt machine. Relative height is lower, the material of the horizontal velocity component, the greater the lateral impact of lower belt Fc also is bigger, the material is also difficult to center.Make the materials on the conveyor belt transect deflection, impact of Fc horizontal component of the Fy eventually led to the belt running deviation. If the material slants to the right, the belt running deviation, and to the left and vice versa. For running deviation in this case, in the design process should be as much as possible to increase both the relative height of the conveyor. In being limited by the space of the belt conveyor and funnel, feed trough and other parts of form and size should seriously consider. General feed slot width is about three 5 of the width of the belt is more appropriate. To reduce or avoid the belt running deviation can increase keep-off plate block material, change of material drop direction and position.
　　7, the perpendicularity error of installation position and the center line of the conveyor, conveyor belts in bearing period to run a partial. For roller conveyor forward runtime a traction Fq forward, the traction force is decomposed into the roller rotating component of Fz and a transverse component of the Fc, the horizontal component of the supporting roller to move, as a result of the idler bracket fixed roller axial channeling is unable to move, it will inevitably produces a reaction Fy to conveyor belt, it is conveyor belt moved to the other side, thereby resulting in the wandering.
　　To clear up the carrying idler group when installing deflection force, it is not hard to understand the cause of the conveyor belt running deviation, adjust the way is clear.
　　The first method is making roller set installation holes are machined to grow on both sides of the hole, in order to adjust. Specific methods is the belt deviation which side, supporting roller group which side of the belt forward direction forward, backwards, or the other side. Upward direction belt running deviation, supporting roller group, should move to the left, under the roller group located on moving to the right.
　　Group the second approach is to install self-aligning roller, self-aligning roller group there are many types, such as intermediate shaft type, four connecting rod type, vertical roll type, etc. Its principle is to use blocking or roller rotation in the horizontal plane directions or resulted from lateral thrust belt automatically to achieve the purpose of running deviation of the belt can be adjusted, the stress distribution and deflection force bearing roller group is the same. Total length is relatively short or generally in belt conveyor belt conveyor two-way runtime USES this method is reasonable, reason is the short belt conveyor is easier to adjust. And it is not easy to The long belt conveyor had better not use this method, because the use of self-aligning roller group will produce certain effect on the service life of the conveyor belt.
