[0036] The fixed support 1 and the clamping plate 2 are respectively arranged on the two opposite sides of the bearing seat 43, and are locked by the locking bolt 3, so that the fixing device is fastened on the bearing seat 43;

[0037] The proximity switch sensor 5 is arranged at one end of the fixed support 1 facing the barrel 41.

[0038] When adjusting the position of the barrel 41, the staff can move the bearing seats 43 at both ends of the barrel 41 towards / away from the fixed roller, so as to make the tension of the belt suitable and meet the work requirements;

[0039] When adjusting the position of the bearing seat 43, the fixing device also moves together with the bearing seat 43, the proximity switch sensor 5 installed on the fixing device and the position relationship of the barrel 41 always remain unchanged, and the situation that the barrel 41 hits the proximity switch sensor 5 due to the reduction of the distance between the barrel 41 and the proximity switch sensor 5 does not occur, so as to ensure the service life of the proximity switch sensor 5; at the same time, the relative position between the sensing end of the proximity switch sensor 5 and the sensing position of the barrel 41 always does not change, which can ensure the detection accuracy of the proximity switch sensor 5.

[0040] In addition, the temperature of the surrounding environment of the proximity switch sensor 5 is high, and the proximity switch sensor 5 is close to the rotating part, which can reduce the maintenance frequency and the work amount of the staff to ensure the service life of the proximity switch sensor 5.

[0041] In some embodiments, the above-mentioned fixed support 1 comprises a fixed plate 11 and a mounting plate 12; wherein,

[0042] The proximity switch sensor 5 is arranged on the mounting plate 12.
