[0029] The cable conductor 3 is used to connect the infrared sensor 2 with the editable logic controller to perform signal transmission;

[0030] An intermediate relay, which is arranged on the cable conductor 3, is used to convert the infrared signal and then input the converted signal into the editable logic controller through the cable conductor 3;

[0032] According to the above description, the infrared sensor 2 of the utility model is installed on both sides of the main frame of the film winding machine through the bracket 1; the infrared sensor collects infrared signals through the cable conductor 3 for transmission. When it is transmitted to the intermediate sensor, the infrared signal will be converted by the intermediate relay, and then the converted signal will be input into the programmable logic controller (PLC) by the cable conductor 3. The programmable logic controller (PLC) instructs the equipment to be forcibly stopped or maintained in operation (here it mainly depends on whether the infrared signal detects that foreign objects have entered the working area). The infrared interlocking protection device can reduce the risk of personnel during operation and improve the safety during operation.

[0033] Furthermore, the intermediate relay and the editable logic controller are installed in the control cabinet 4, so that the intermediate relay and the editable logic controller can be protected by the control cabinet 4 to prevent them from being damaged by collision.

[0035] The bracket 1 includes an N-shaped plate 101 fixed to the main frame of the film winding machine, the upper and lower ends of the N-shaped plate 101 are fixedly connected to bearing seats 102, and the interior of the bearing seats 102 is fixedly connected to support bearings 103, a rotating rod 104 is fixedly connected to the inner ring of the support bearing 103, and a screw 105 is fixedly connected between the rotating rods 104, and a rod sleeve 106 is threadedly connected to the outer wall of the screw 105. Limiting components 108 for maintaining the vertical linear movement of the rod sleeve 106 are provided on both sides of the interior of the N-shaped plate 101. A circular groove seat 109 is fixedly connected to the surface of the rod sleeve 106, and its surface is open. A columnar block 110 is rotatably connected to the interior thereof, and the circular groove seat 109 and the columnar block 110 are connected by The fixing structure 107 is used for fixing, the surface of the columnar block 110 is fixed to the cable sensor through the connecting rod 111, the limiting component 108 includes guide rails fixed on both sides of the N-shaped plate 101, and the two sides of the rod sleeve 106 are slidably connected in the guide rails through sliders. The fixing structure 107 includes a through hole 1071 opened on the top of the circular groove seat 109, and a plurality of screw holes 1072 arranged in a circular array on the outer wall of the columnar block 110, a screw is installed above the through hole 1071, and the screw passes through the through hole 1071 downward in turn and then rotates clockwise to be installed in the screw hole 1072, and a handle 112 is installed on the end of the rotating rod 104 opposite to the screw rod 105 to facilitate its rotation.

[0036] By rotating the rotating rod 104 clockwise or counterclockwise through the handle 112 (it should be noted that the handle 112 can be selectively installed on the upper or lower rotating rod 104 to facilitate the operation of the staff), the rotating rod 104 drives the inner ring of the supporting bearing 103 to rotate, and the inner ring rotates along its outer ring. At the same time, the rotating rod 104 drives the rotation of the screw rod 105, and the screw rod 105 drives the rod sleeve 106 to move up and down.

The rod sleeve 106 drives the circular groove seat 109 to move up and down, thereby achieving the purpose of adjusting the height of the infrared sensor 2. When the height is adjusted After the joint is completed, the infrared sensor 2 can be rotated. The infrared sensor 2 drives the rotation of the column block 110 through the connecting rod 111, and the column block 110 rotates along the inside of the circular groove seat 109 (it should be noted that the column block 110 can be close to the inner surface of the circular groove seat 109, and the opening of the circular groove seat 109 is small, and the column block 110 will not slide out of the opening) to adjust the angle of the infrared sensor 2. After the angle adjustment is completed, the angle of the infrared sensor 2 can be fixed by passing the screw through the through hole 1071 on the circular groove seat 109, and then rotating it clockwise to install it into the screw hole 1072 of the corresponding angle of the column block 110.
