Abstract

This utility model belongs to the field of needle-punched nonwoven fabric processing technology, and in particular to a constant tension control mechanism for a winding roller of a roll forming machine. It includes a base plate, on the upper surface of which a housing, a constant tension control device, and two temperature sensors are fixedly connected. The housing covers the constant tension control device and temperature sensors. A tube frame is installed inside the housing. Two sets of rotating rods are rotatably connected to the inner wall of the housing. A water chiller is installed on the right side of the housing. The output and input ends of the water chiller penetrate the housing and are fixedly connected to the outer surface of the tube frame. Two sets of electric push rods are fixedly connected to the inner top wall of the housing. By setting up the housing and the water chiller, a circulating cooling system is formed using the water chiller and the tube frame. Simultaneously, the combined design of the electric push rods and electric heating tubes allows for flexible adjustment of the heating position and intensity according to actual needs, effectively regulating the temperature environment inside the housing and reducing the impact of temperature fluctuations on the material's elastic modulus and the roller's friction coefficient.
