Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.

[0019] Referring to Figures 1-3 , the utility model provides an embodiment: a kind of dead weight formula exhaust mechanism in the process of cloth spreading of cloth spreading machine, including crossbeam 1 and exhaust roller 2, the both ends of crossbeam 1 are fixedly connected with sliding groove support 3, the inner wall of sliding groove support 3 is fixedly connected with sliding groove insert 4, the both ends of exhaust roller 2 are provided with sliding bearing 5, the both ends of exhaust roller 2 are provided with rolling bearing 8, the both ends of exhaust roller 2 are provided with fixed ring 9, the outer wall of rolling bearing 8 and fixed ring 9 is provided with lower support 7, the upper surface of lower support 7 is fixedly connected with tension spring 10, the top of tension spring 10 is fixedly connected in the inner top wall of sliding groove support 3;

[0020] Specifically, the crossbeam 1 can play a role of fixing and supporting the chute support 3, the chute support 3 can play a role of fixing and supporting the chute insert 4, the exhaust roller 2 can play a role of supporting the sliding bearing 5, the exhaust roller 2 can play a role of supporting the rolling bearing 8, the exhaust roller 2 can also play a role of supporting the fixed ring 9, the rolling bearing 8 and the fixed ring 9 can play a role of supporting the lower support 7, and the chute support 3 can play a role of fixing and supporting the tension spring 10, the tension spring 10 can pull the lower support 7, so that the lower support 7 can pull the exhaust roller 2 upward, the exhaust roller 2 has a certain weight, the weight can generate a downward pressure, the pressure can directly act on the cloth, the tension spring 10 can provide an upward elastic force to offset part of the weight of the exhaust roller 2, so as to reduce the downward pressure of the exhaust roller 2, so as to avoid the adverse effect of excessive pressure on the cloth, and the tension spring 10 can be replaced, different tension springs 10 can be used to increase or reduce the downward pressure of the exhaust roller 2, the air in the cloth can be removed through the extrusion of the exhaust roller 2, the flatness and laying quality of the cloth are improved, and a better foundation is provided for subsequent processing steps.
