Abstract

The utility model belongs to the technical field of needle-punched non-woven fabric processing, and particularly relates to a constant tension control mechanism for a winding roller of a lapper, which comprises a bottom plate, the upper surface of the bottom plate is fixedly connected with a shell, a constant tension control device and two temperature sensors respectively, and the shell is covered outside the constant tension control device and the temperature sensors. A pipe frame is arranged in the shell, two sets of rotating rods are rotationally connected to the inner wall of the shell, a water cooling machine is arranged on the right side of the shell, the output end and the input end of the water cooling machine penetrate through the shell and fixedly communicate with the outer surface of the pipe frame, and two sets of electric push rods are fixedly connected to the inner top wall of the shell. A circulating cooling system is formed by the water cooling machine and the pipe frame, meanwhile, the combined design of the electric push rod and the electric heating pipe is combined, the heating position and strength can be flexibly adjusted according to actual requirements, the temperature environment in the shell can be effectively adjusted and controlled, and the influence of temperature fluctuation on the material elasticity modulus and the roller body friction coefficient is reduced.
