Description

Technical Field

[0001] The utility model relates to a conveying roller, in particular to a conveying roller capable of avoiding scratching the surface of strip steel, and belongs to the technical field of strip steel transportation equipment. Background Art

[0002] During the rolling process of the strip, the movement of the strip is driven by a roller table. Since the roller table is in a high temperature and high humidity environment for a long time and is not properly maintained, the driving rollers in the roller table may not rotate. This will cause hard friction between the surface of the strip passing at high speed and the abnormal rollers, resulting in scratches on the surface of the strip. The scratches on the surface of the strip directly affect the product quality of the strip. The appearance of abnormal rollers is sporadic. Even if they can be found, the replacement time of the rollers is long. In order to ensure production continuity, they are generally replaced during maintenance time. Therefore, the influence of the abnormal rollers on the strip cannot be eliminated in time. Therefore, a conveying roller table is required, which is required to be able to detect and evacuate abnormal rollers in time, thereby reducing the influence on the surface of the strip.

[0017] The limiting mechanism includes a limiting member, a long strip plate 6 and a spring; a strip groove is provided on the upper end surface of the base 1 along its length direction, and the long strip plate 6 is arranged in the strip groove of the base 1; the spring is arranged in the strip groove on the upper end surface of the base 1, and the top end of the spring contacts the bottom end of the long strip plate 6; the spring provides an upward force for the long strip plate 6; the top end of the long strip plate 6 contacts the first right-angle surface of the triangular block 5; the long strip plate 6 is evenly provided with a plurality of threaded holes along its length direction; the number of the limiting members is two, and they are symmetrically arranged at both ends of the long strip plate 6.

[0021] Actual use process: In the initial state, the piston rod of the cylinder 7 is in the retracted state, and the two triangular blocks 5 are restricted by the limit blocks, and the lifting plate 2 cannot be lifted or lowered; in the production process, once the data parameters sensed by a certain angle sensor 11 are significantly different from the sensing parameters of the adjacent angle sensor 11, it means that the conveying part corresponding to this angle sensor 11 has a fault, and the roller 10 cannot transport the strip steel well; then the cylinder 7 in this conveying part is actuated, driving the long strip plate 6 to press down, and the limit block 8 no longer restricts the triangular block 5. At this time, the triangular blocks 5 are close to each other, and at this time the two vertical plates 4 move downward, driving the lifting plate 2 to move downward synchronously, and finally the roller 10 cancels the contact with the strip steel, avoiding the damage to the strip steel surface caused by the faulty non-rotating roller 10.
