Description

Technical Field

[0001] The utility model relates to the field of belt conveyors, in particular to a belt adjusting device. Background Art

[0002] Belt conveyors are widely used in mining, chemical, waste disposal and other industries. Due to various reasons such as processing, assembly, uneven load, etc., the resultant force of the external force on the belt in the belt width direction is not zero, which causes the reaction force of the roller or drum on the belt to produce a component force to one side. Under the action of this component force, the belt deviates to one side. The belt deviation problem has become a pain point in the industry, and major manufacturers are looking for belt deviation prevention methods suitable for the application scenarios of their products. At present, the main methods for flat belt deviation correction are: improving processing accuracy, ensuring material uniformity with guide plates, repairing drums, adding belt pressure wheels, etc. Except for adding a pressure roller, other correction methods have little effect in harsh conveying environments, wet materials and other working conditions. Adding a pressure roller can effectively prevent the belt from rubbing against the side plate of the belt conveyor, ensuring that the motor is not overloaded, thereby ensuring smooth transportation. However, the edge of the belt will always roll relative to the pressure roller. On the one hand, the pressure roller becomes a consumable due to long-term excessive pressure. On the other hand, long-term contact between the belt edge and the pressure roller will cause the protective rubber layer on the side of the belt to fall off and be damaged prematurely, thereby affecting the service life of the belt. Therefore, the pressure roller does not fundamentally solve the problem of belt deviation. Utility Model Content

[0102] In this embodiment, the first safety cleaning shield 71 and the second safety cleaning shield 72 are used to prevent people's fingers from being drawn into the lower side of the adjustment roller (the first adjustment roller 23 and the second adjustment roller 33) to cause personal injury, and can also prevent other substances from being drawn into the lower side of the adjustment roller to cause failure such as material jamming. At the same time, the upper shield can effectively remove the adhesions adhering to the adjustment roller, ensure the cleanliness of the adjustment roller, and do not generate additional additional force to prevent the belt 6 from forming an unbalanced force again; wherein, the first safety cleaning shield 71 is arranged on the first adjustment bracket 22 of the first adjustment assembly 2, and is connected to the first adjustment bracket 22 of the first adjustment assembly 2. The two ends of an adjustment bracket 22 are fixedly connected and wrapped around the outside of the first adjustment roller 23. The side of the first safety cleaning shield 71 is at a preset distance from the first adjustment roller 23, and the preset distance can be automatically adjusted according to needs; the second safety cleaning shield 72 is arranged on the second adjustment bracket 32 ​​of the second adjustment component 3, and is fixedly connected to the two ends of the second adjustment bracket 32, wrapped around the outside of the second adjustment roller 33.

[0103] like Figure 2and Figure 3 As shown, the belt adjustment device described in the utility model has the following specific working principles:

[0104] in, Figure 2 81 is the driving roller of the belt conveyor, 82 is the driven roller, and 6 is the transmission belt;

[0105] When in use, the other end of the adjusting bracket 42 (the first adjusting bracket 22 and the second adjusting bracket 32) is lifted up by increasing the feed amount of the adjusting bolt (the first adjusting bolt 42 and the second adjusting bolt 52), and is rotated and adjusted around the fixing bolt (the first fixing bolt 211 and the third fixing bolt 311) until it is adjusted to a preset angle. By adjusting the angle, the adjusting rollers (the first adjusting roller 23 and the second adjusting roller 33) can be "turned up" respectively (that is, they can respectively generate an upward thrust on the end surface of the belt 6), and each independently forms a thrust F perpendicular to the belt. Since it is turned over, the thrust has a horizontal component F' toward the middle, thereby achieving the adjustment of the belt 6; when deviation occurs, the adjustment balance can be achieved by adjusting the angle of one side; for a belt conveyor working in both directions, the deviation is more serious, and the traditional method of tightening the belt on one side cannot achieve the adjustment of the bidirectional belt at all; since the utility model is independently adjusted, for the adjustment of the bidirectional belt, as long as the angles of the left and right rollers are adjusted respectively, there is also a good adjustment effect.

[0106] In a preferred embodiment, the preset angle ranges from 0 to 12 degrees.

[0107] The belt adjustment device of the utility model uses the angle of the adjustment roller to adjust so that a relatively uniform thrust F perpendicular to the belt 6 is generated on the belt 6. Because of the angle, a thrust component F' deflected toward the center is formed on the belt 6, so that the belt 6 is evenly stressed. At the same time, because the adjustment roller is stressed on the entire roller surface, the service life of the belt 6 and the adjustment roller is effectively extended; at the same time, the adjustment space is small, and only a certain angle needs to be adjusted to generate an intermediate thrust. The thrust increases with the increase of the angle, and the adjustment range is large. For the bidirectional belt 6, different centripetal forces can be generated because of the independent angle adjustments. At the same time, adjusting the adjustment rollers on both sides can effectively ensure the smooth operation of the bidirectional belt 6; each adjustment roller is provided with a safety cleaning shield (a first safety cleaning shield 71 and a second safety cleaning shield) on the outside 71), on the one hand, it can ensure the safety of personnel, and at the same time, it can avoid the occurrence of material jamming and the like. The upper side of the protective cover can clean and scrape the surface of the adjustment roller to prevent the sticky material from solidifying on the adjustment roller, introducing other unbalanced forces, and avoiding adjustment failure; the belt adjustment device described in this embodiment is designed by a "segmented" belt adjustment device. By adjusting the angles of the left and right symmetrical adjustment rollers, the belt 6 can have independent tensioning forces on both sides of the width direction, and the adjustment effect is good. It can also have a certain adjustment effect on the bidirectional belt, realize the rapid adjustment of the belt during the operation of the belt conveyor, prevent the deviation of the belt, and ensure the stability of the working state of the belt conveyor. At the same time, it has the advantages of simple structure, low cost, good correction effect and little damage to the belt.

[0108] The above is a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
