Referring to fig. 1 to 3, in the present embodiment, a tension maintaining mechanism suitable for rolling a chain belt includes a base 10, a creel stand 9 disposed at a front end of the base 10, a belt stop roller set 7 disposed above a middle portion of a top surface of the base 10, and a roller set 8 hinged at a rear end of the base 10, where the chain belt is first pushed forward to the belt stop roller set 7 from the creel stand 9 and then wound around the roller set 8, so that the chain belt forms tension in a normal pushing process. Specifically, the creel stand 9 is in a rectangular frame 81 structure, a plurality of winding displacement wheels 91 are transversely fixed on the creel stand 9 so as to push disordered chain belts to the belt-stopping pinch roller set 7 in a way of winding the winding displacement wheels 91 in a winding way; the pressing wheel set 8 includes a frame 81 and a pressing wheel 82 sleeved on the top end of the frame 81, wherein the tail of the frame 81 is hinged on the rear end of the base 10, so that the chain belt is tightened when the chain belt passes around the pressing wheel 82.

In this embodiment, referring to fig. 2, the belt-stopping pressure roller set 7 includes an installation seat 1, a pressing roller 2, a brake roller 3 and an electromagnetic brake 4; the mounting seat 1 includes a supporting seat 11 and two horizontally aligned supporting plates 12, which are both fixedly connected to the top surface of the base 10, wherein the supporting seat 11 is rectangular and long and is disposed behind the two supporting plates 12. The pressing wheel 2 is rotatably connected to the top end of the supporting seat 11, the brake wheel 3 is rotatably connected between the two supporting plates 12, the roller surface of the pressing wheel 2 is tightly attached to the roller surface of the brake wheel 3, the pressing wheel 2 is arranged above the brake wheel 3, and a chain guide groove 21 for a chain belt to pass through is formed in the roller surface of the pressing wheel 2. The electromagnetic brake 4 is fixed on the rotating shaft of the brake wheel 3, and the brake of the rotating shaft is directly stopped through the electromagnetic brake 4, so that the brake wheel 3 on the rotating shaft is stopped.
