[0013] This utility model relates to a stable feeding mechanism for a conveyor belt. A drive roller is rotatably mounted on the outer side of a mandrel above a take-up shaft. One end of the mandrel passes through a mounting plate and connects to the output shaft of a take-up motor. Both the take-up shaft and the mandrel are equipped with pulleys located on the rear side of the mounting plate, connected by a belt drive. A rotating plate is located on the front side of the mounting plate. The upper end of this rotating plate is rotatably mounted on the mounting plate via a pin. A clamping roller is rotatably mounted on the lower end of the rotating plate, parallel to one side of the drive roller. A first connecting pin is located on the upper side of the rotating plate opposite to the drive roller. A spring connects this first connecting pin to a second connecting pin located on the upper surface of the rotating plate, causing the clamping roller at the lower end of the rotating plate to press against the drive roller. A track and slider are mounted on the front surface of the strip-shaped vertical plate between the first and second guide rollers. A movable plate that can move left and right has a first movable roller and a second movable roller rotatably mounted on the front sides of its left and right ends, respectively.

The material strip from the feeding component passes sequentially between the first guide roller, the second movable roller, the first movable roller, the second guide roller, and the clamping roller and power roller of the take-up component before winding onto the take-up shaft. This allows the second surface of the material strip, whose first surface is in rolling contact with the outer circumference of the second movable roller, to also be in rolling contact with the outer circumference of the first movable roller. This not only enables stable winding of the material strip after use but also allows for replenishment of the material strip. Furthermore, the movable roller, which moves back and forth with the movable plate, provides reverse drive to the material strip when the take-up component is not winding it, thus separating the use process of the material strip from the winding process after use. This improves the stability, uniformity, and controllability of the material strip's movement speed during use. Attached Figure Description
