Detailed Description
The present invention will be further described with reference to the accompanying drawings and examples.
As shown in fig. 1 to 6, a steel band ultra-wide detection control apparatus for a spiral spring, comprising:
a base 5;
the width detection plate 1 is provided with a groove 11 at the upper part, and the width of the groove 11 is matched with the width of the detected steel strip 3 and is generally equal to the upper limit value of the steel strip width; a first connecting pin 12 is further arranged below the groove 11, and a lower part 13 of the width detection plate is rotatably arranged on the base 5 through a cylindrical pin shaft 9;
a limiting member 8 which is arranged on the base 5 and abuts against one side of the lower part 13 of the width detection plate, and the limiting member 8 limits the width detection plate 1 to only rotate towards the movement direction of the steel strip, so as to prevent the width detection plate 1 from reversely rotating;
the extension spring bracket 6 is arranged behind the width detection plate 1, a second connecting pin 61 penetrating through the extension spring bracket 6 is arranged at the upper part of the extension spring bracket 6, and the lower end of the extension spring bracket is fixed on the base 5;
the width detection plate comprises two extension springs 4, wherein one end of one extension spring 4 is connected with one end of a first connecting pin 12 at the upper part of the width detection plate 1, the other end of the extension spring 4 is connected with one end of a second connecting pin 61 at the same side as the upper part of an extension spring support 6, one end of the other extension spring 4 is connected with the other end of the first connecting pin 12 at the upper part of the width detection plate 1, and the other end of the other extension spring 4 is connected with the other end of the second connecting pin 61 at the same side as the upper part of the extension spring support 6, so that when the width detection plate 1 rotates towards the steel strip advancing direction A due to the super width of the steel strip, the width detection plate can be prevented from falling;
and the photoelectric sensing switch 2 is arranged at the adjacent position of the outer side of the width detection plate 1, is opposite to the width detection plate 1, senses and sends a feedback signal, and is received and processed by a control system of the steel strip production equipment.
When the steel belt ultra-wide detection control device for the flat spiral spring is applied to steel belt detection, in a normal state, the processed steel belt 3 smoothly passes through the groove 11 of the width detection plate 1 due to the fact that the width of the steel belt is smaller than the width of the groove 11, the processed steel belt is not obstructed by the width detection plate 1, and the width detection plate 1 is kept still.
When the steel band 3 of processing has super wide department 31, can receive the hindrance of width detection board when its super wide department 31 passes through the recess 11 of width detection board, will drive width detection board 1 and rotate forward and break away from photoelectric sensing switch's induction zone, at this moment photoelectric sensing switch 2 will receive the change of signal, send feedback signal to steel band production facility immediately, send corresponding control instruction by steel band production facility's control system, pause steel band production facility, the operator just can in time make correct processing to super wide steel band, prevent the production of steel band product quality hidden danger.
The distance between the top 111 of the groove 11 of the width detection plate 1 and the surface of the steel strip 3 is small, preferably 3 to 6 mm. Because the distance between the top of the groove of the width detection plate and the plane of the steel belt is small, after the width detection plate is driven by the ultra-wide part 31 of the steel belt 3 to rotate for a certain angle, the steel belt can be separated from the width detection plate, so that the steel belt can also continue to move forwards, and accidental damage to the steel belt and equipment caused by the blocking of the steel belt by the width detection plate 1 can be avoided.
