Wherein, axis of rotation 2 rotates with fixed bolster 3 to be connected, and on axis of rotation 2 was worn to locate by chassis 1, metal strip coil 6 set up on chassis 1, is provided with one on the chassis 1 simultaneously and surveys mouthful 5. As shown in fig. 2, the detecting opening 5 is a slit penetrating the thickness of the chassis 1, and the slit is arranged along the radial direction of the chassis 1 and extends to the outer side wall of the chassis 1. The sliding detection assembly 4 comprises a coil, a sliding groove 41, a driving assembly and a sliding detector 42, wherein the sliding groove 41 is arranged on the fixed support 3 and is arranged along the radial direction of the metal strip coil 6, the driving assembly is connected to the sliding detector 42 and is used for driving the sliding detector 42 to slide along the sliding groove 41, and the coil is arranged in the sliding groove 41 and is connected with the sliding detector 42 to form a variable resistance circuit.
Specifically, the slide detector 42 includes a metal slider 421 and an infrared distance sensor 422, the metal slider 421 is slidably disposed on the chute 41 and is simultaneously in contact with the coil, and the infrared distance sensor 422 is connected to the metal slider 421. The driving assembly comprises a motor and a reduction gear box, wherein the inlet end of the reduction gear box is connected with the motor, and the outlet end of the reduction gear box is connected with the metal sliding block 421.
Further, the infrared distance measuring sensor 422 and the motor are electrically connected with the controller, and a circuit formed by the coil and the metal slider 421 is also electrically connected with the controller. The structure of the controller is a conventional control circuit in the art, and is integrated on the control board, and therefore the invention point of the present scheme is not described here, and is not described herein again.
Specifically, the rotating shaft 2 drives the chassis 1 and the metal strip coil 6 to rotate synchronously so as to realize strip releasing, and the infrared distance measuring sensor 422 arranged on the back surface of the chassis 1 detects the residual length of the metal strip coil 6 through the detection port 5. When the metal strip coil 6 cannot be detected at the detection point position, the controller controls the motor to rotate, drives the sliding detector 42 to move towards the axis direction of the rotating shaft 2 until the infrared distance measuring sensor 422 detects the metal strip coil 6 again, and the following of the sliding detector 42 to the thickness edge of the metal strip coil 6 is realized in such a reciprocating manner. Meanwhile, the length of the part of the coil connected to the variable resistance circuit is changed due to the sliding of the metal sliding block 421, the electric signal transmitted back to the controller is changed accordingly, and the controller processes the electric signal and calculates the position of the sliding detector 42, namely the position of the thickness edge of the metal strip coil 6, and then calculates the residual thickness of the metal strip coil 6.
In the prior art, the controller sets the unwinding speed to be constant when calculating the remaining time of the metal strip coil 6. However, the actual production speed of the production line is often variable, and the remaining time displayed by the system is inaccurate.
