Description

Technical Field

[0001] The utility model relates to the technical field of conveyor belt deviation correction, in particular to a return V-shaped cone double-roll automatic deviation correction system. Background Art

[0002] During the operation of the belt conveyor, problems such as material adhesion, spillage, uneven flow, and improper installation of the roller frame can easily lead to belt deviation, which is a common and serious fault. Deviation not only damages the conveyor belt, but also increases the axial force of the roller, roller and other components, affecting production.

[0003] Existing deviation-correcting devices such as differential self-aligning rollers and hydraulic / electric control systems have problems such as unsatisfactory effects, easy wear of belt edges, and control failure. Among them, the rotary deviation-correcting device is widely used because of its low cost and the ability to automatically adjust the deviation-correcting force according to the degree of deviation. During the installation process, it is necessary to maintain sufficient deviation-correcting tension, which is usually achieved by adjusting the height of the deviation-correcting roller. However, the current rotary deviation-correcting device is usually only adjusted by height-adjusting bolts, and its height-adjusting range is limited. Although the height-adjusting range can be increased by increasing the height-adjusting bolts, it will affect its stability.

[0004] Therefore, it is necessary to propose a return V-cone double-column automatic deviation correction system to solve the above problems. Utility Model Content

[0029] When the belt deviates, the friction increases due to the different roller surface linear speeds at both ends of the tapered roller 2. The tapered roller 2 on the offset side of the belt is subjected to increased force and rotates forward. The tapered roller 2 is tilted relative to the direction of belt movement to correct the belt deviation.

[0030] Both ends of the support frame 7 are horizontally slidably connected with a movable frame 9, and the movable frame 9 and the support frame 7 are fixed in position by fastening bolts 8.

[0031] By setting a relatively sliding support frame 7 and a movable frame 9, adjusting the overall length and fixing the frame in position by tightening bolts 8, the frame can be adapted to the frame of belt conveyors of different widths for easy installation and fixation; by setting an end plate 11 and a height-adjusting plate 12, when adjusting its height, the height of the tapered roller 2 can be infinitely adjusted by setting a height-adjusting bolt 14, and a plurality of through holes 15 are set to adjust the fixed height of the height-adjusting plate 12 to increase its adjustment range. After height adjustment, the movable frame 9 is fixed to the end plate 11 by a first bolt to further improve its stability. At the same time, a strip hole 16 for the first bolt to pass through is opened on the end plate 11, so that during the height adjustment process, only the first bolt needs to be loosened without completely unscrewing it.

[0032] In order to facilitate the adjustment of the inclination angle of the tapered roller 2, the small diameter end of the tapered roller 2 is fixedly connected to the V-shaped frame 1 through the adjusting bolt 6.

[0036] When adjusting the overall length, loosen the fastening bolt 8, then slide the slide bar, and after adjusting to a suitable length, tighten the fastening bolt 8, and the fastening bolt 8 presses the slide bar to fix the length.

[0037] In order to avoid mutual interference between the movable frame 9 and the height adjustment plate 12, the movable frame 9 and the height adjustment plate 12 are respectively located on both sides of the end plate 11, and a fixed block 13 is fixedly connected to one end of the movable frame 9 away from the support frame 7, and the fixed block 13 is fixedly connected to the height adjustment plate 12 through a height adjustment bolt 14;

[0038] During the installation process, in order to facilitate the fixation of the movable frame 9 and the end plate 11 , the fixing block 13 passes through the end plate 11 through the U-shaped groove 17 so that the fixing block 13 can be pushed in from one side of the end plate 11 .

[0039] In order to further improve its height adjustment range, it also includes an expansion piece 10, which is fixedly connected to the top of the end plate 11 by bolts.
