Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The following detailed description is given to specific implementations of the present invention with reference to specific embodiments:

as shown in fig. 1, a BOPS sheet production line nip roll anti-crushing protection device includes: nip roll 1, infrared induction receiver 2, infrared induction transmitter 3, powered roll 4, MDO1 zone nip roll 5, MDO2 zone nip roll 6, film bridge zone nip roll 7, corona zone nip roll 8, coating zone nip roll 9, PLC10, MDO1 zone nip roll controller 11, MDO2 zone nip roll controller 12, film bridge zone nip roll controller 13, corona zone nip roll controller 14, and coating zone nip roll controller 15, MDO1 zone nip roll, MDO2 zone nip roll, film bridge zone nip roll, corona zone nip roll, and coating zone nip roll, respectively, the nip roll and powered roll pairs are arranged in parallel, the infrared induction receiver and infrared induction transmitter pairs are respectively mounted on the axial sides of each nip roll, the MDO1 zone nip roll controller, MDO2 zone nip roll controller, film bridge zone nip roll controller, corona zone nip roll controller, and coating zone nip roll controller are respectively in electrical communication with the MDO 23 zone nip roll, coating 734 zone nip roll, corona zone nip roll controller, the infrared induction receiver and the infrared induction transmitter are electrically connected with a PLC, and the MDO1 area nip roll controller, the MDO2 area nip roll controller, the film bridge area nip roll controller, the corona area nip roll controller and the coating area nip roll controller are respectively electrically connected with the PLC; the infrared induction receiver and the infrared induction transmitter detect shielding signals of all the clamping rollers in the axial direction and feed back the shielding signals to the PLC, the PLC outputs control signals to the MDO1 area clamping roller controller, the MDO2 area clamping roller controller, the film bridge area clamping roller controller, the corona area clamping roller controller and the coating area clamping roller controller, and the MDO1 area clamping roller, the MDO2 area clamping roller, the film bridge area clamping roller, the corona area clamping roller and the coating area clamping roller are respectively controlled to be opened.
