[0026] The door panel 601 can be opened and closed by connecting the spring 603. When the door panel 601 is closed, it is used to protect the photoelectric sensor 205. Specifically, when the first vertical plate 203 is extended and retracted downward to control the detection shell 204 to slide out, the bottom of the first vertical plate 203 will provide a downward force on the door panel 601. At this time, the connecting spring 603 rotatably connected to the second lock buckle 604 of the door panel 601 forms a rotating structure with the protective shell 2 through the first lock buckle 602, so that the door panel 601 can be elastically opened and closed through the connecting shaft 6.

When the work is completed, the elastic member 402 can be pressed again to separate it from the bottom of the locking block 404. Through the elastic recovery of the first spring 201, the detection shell 204 is retracted to the inside of the protective shell 2, which can provide a protective barrier to protect the photoelectric sensor 205 from mechanical damage such as accidental collision, impact or extrusion, and reduce the space on the equipment to avoid the equipment occupying too much space due to the protruding sensor.

[0029] In a preferred embodiment, the adjustment component includes an adjustment groove 101 opened on the front and rear walls of the bracket base 1, the inner wall of the adjustment groove 101 is rotatably connected to a screw rod 102, the interior of the adjustment groove 101 is slidably connected to a slider 103, and the slider 103 is threadedly connected to the screw rod 102, and the support frame 104 is located on the side wall of the slider 103 and is fixedly connected, the screw rod 102 is driven by a motor to enable the slider 103 to slide along the inside of the adjustment groove 101 through the screw rod 102, so that the support frame 104 can slide on the bracket base 1, driving the protective shell 2 on the support frame 104 to adjust, thereby moving the photoelectric sensor 205 inside the detection shell 204.

[0030] In a preferred embodiment, conveying rollers 7 are respectively provided at the edges of both sides of the upper end surface of the bracket base 1, and the conveying rollers 7 are respectively used to convey the yarns of the fiber polyester-viscose cloth. The conveying rollers 7 are arranged lower than the supporting rollers 502 to ensure that the supporting rollers 502 are squeezed downward during the yarn transmission.

The broken thread detection work is performed through the photoelectric sensor 205. When the fiber polyester-viscose yarn is being transported, it is supported above the support roller 502, providing a downward force to the support roller 502, and then the support plate 501 is compressed inside the cavity groove 5 through the second spring 504. When the yarn breaks, the force is reduced, and the second spring 504 slightly bounces upward. Further detection is performed through the pressure sensor 505. The dual detection mechanism can greatly improve the accuracy of detection and reduce the possibility of false alarms and missed alarms.

[0032] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0033] During operation, the polyester-viscose yarn is transported through the transport roller 7 and the support roller 502. Then, during detection, the pressing plate 202 is compressed on the protective shell 2 through the first spring 201 and the telescopic sleeve 3, driving the detection shell 204 on the first vertical plate 203 to slide downward along the protective shell 2, so that the photoelectric sensor 205 inside the detection shell 204 can slide out of the protective shell 2 for detection. At the same time, the elastic member 402 with a U-shaped structure is squeezed to make the stopper 403 and the stopper 403 move downward. The locking block 404 is separated. When the detection housing 204 moves out of the protective housing 2, the stopper 403 contacts the bottom of the locking block 404 and squeezes each other to achieve locking of the second vertical plate 4 and the first vertical plate 203, thereby ensuring that the detection housing 204 is outside the protective housing 2. When the work is completed, the elastic member 402 can be pressed again to separate it from the bottom of the locking block 404. The elastic recovery of the first spring 201 allows the detection housing 204 to be retracted into the interior of the protective housing 2, thereby providing a protective barrier.

[0034] When the first vertical plate 203 is extended and retracted downward to control the sliding out of the detection shell 204, the bottom of the first vertical plate 203 will provide a downward force on the door panel 601. At this time, the connecting spring 603 rotatably connected to the second lock buckle 604 of the door panel 601 forms a rotating structure with the protective shell 2 through the first lock buckle 602, so that the door panel 601 can be elastically opened and closed through the connecting shaft 6. When the detection shell 204 is retracted inside the protective shell 2, the door panels 601 on both sides are retracted through the connecting spring 603, which improves the convenience of the equipment and places the protective shell 2 in a closed space, thereby protecting the photoelectric sensor 205 in the detection shell 204.
