[0002] Hot rolling is the last web forming technology in the production process of non-woven fabrics. It is a process to form the fabric after cooling and laying filaments. In hot rolling, a high-temperature rolling wheel rolls over uniform fiber filaments to make them melt and form a web. Therefore, there will be rolling points on the surface of the hot-rolled non-woven fabric, similar to pinholes, but not penetrating. The specific size depends on the size and density of the steel spines on the rolling wheel.

Most of the ejector pins on the hot rolling forming rollers on the market are integrated with the roller, resulting in non-adjustable ejector pin heights. Therefore, only the hot rolling forming roller can be replaced, but this operation is cumbersome and time-consuming, and the replacement is very inconvenient, and the overall effect is not good. Accordingly, the utility model provides a hot rolling forming device for non-woven products. Summary of the Utility Model

A central hole 4 is opened on the end cap 2. An adjusting shaft 5 extending into the hollow shaft is rotatably connected in the central hole 4. A camshaft 6 is connected in series between the adjusting shafts 5. N protruding portions 61 extending axially are circumferentially distributed on the side surface of the camshaft 6. N rows of needle holes 7 axially spaced and matching the protruding portions are opened on the roll body 1. A thimble 8 is slidably connected in the needle hole 7. A limiting portion 9 is provided at one end of the thimble 8 close to the protruding portion. An elastic member 10 is sleeved on the thimble 8. The elastic member 10 is a compression spring with one end abutting against the roll body and the other end abutting against the camshaft. An electric heating component 11 is arranged on the inner wall of the roll body 1; the electric heating component 11 is an electric heating tube; N≥3.
