AI Technical Summary
Existing asphalt root-penetration resistant waterproof membranes are prone to loosening and expansion during use, resulting in low laying efficiency and inconvenience. Furthermore, the non-adjustable spring force prevents the extrusion shaft from tightly adhering to the membrane, affecting the expansion control effect.
It adopts a combination structure of lead screw, motor, hydraulic cylinder and spring. The motor drives the lead screw and rectangular plate to move and adjust the support plate. Combined with the hydraulic cylinder to compress the spring and adjust the elastic force, it can achieve tight fit of the extrusion rollers to adapt to different specifications of roll materials. The vertical plate spacing can be adjusted by the screw and the second motor to adapt to roll materials of different widths.
It ensures that the roll material remains tightly fitted during use, preventing expansion, improving laying efficiency and ease of use, and adapting to the needs of roll materials of different specifications and widths.
