AI Technical Summary
The existing carding machine triple roller mechanism cannot accurately adjust the tension, which causes the cotton mesh to be easily broken when drafted, and the short lint on the peeled cotton mesh can easily stick to the cotton mesh or be wrapped on the shaft, affecting the normal operation of the carding machine.
A triple roller mechanism including a cotton mesh pallet, cleaning roller and suction hood is designed. The cotton mesh pallet provides support and guidance to the cotton mesh through its polygonal shape and acute angle design to avoid breaking the net. The cleaning roller and suction hood remove the short lint produced through the suction port to prevent it from sticking or wrapping.
The problem of cotton mesh being broken is effectively avoided, and by removing short lint, the quality of cotton mesh and the normal operation of the carding machine are improved.

Description
Technical Field
[0001] The utility model relates to the technical field of carding machine equipment, in particular to a three-roller mechanism of a carding machine. Background Art
[0002] The three-roller mechanism in a carding machine mainly consists of a stripping roller, an upper roller and a lower roller. Among them, the stripping roller interacts with the cotton web on the surface of the doffer through the card clothing or saw teeth on its surface to strip the cotton web from the surface of the doffer. The upper roller and the lower roller cooperate to support and guide the cotton web stripped from the surface of the doffer, so that the cotton web can be output at a smaller downward punch angle, thus avoiding the breakage phenomenon caused by the sagging of the cotton web.
[0003] However, the tension of the existing three-roller mechanism cannot be precisely adjusted. When drafting the cotton web, too close or insufficient tension will cause the cotton web to contract or relax, and ultimately may break the cotton web, affecting the quality of the cotton web and the normal operation of the carding machine. And because the card clothing on the stripping roller is easy to generate short fibers when stripping the cotton web, these short fibers adhere to the surface of the cotton web along with the stripping roller, thus affecting the quality of the cotton web. Moreover, the short fibers are very easy to wind around the end of the rotating shaft, affecting the normal operation of the carding machine. Summary of the Utility Model
[0004] Aiming at the problems that the existing three-roller mechanism is easy to cause the cotton web to break, and the generated short fibers are easy to adhere to the surface of the cotton web, affecting the quality of the cotton web, and even winding around the end of the rotating shaft, affecting the normal operation of the carding machine, the utility model discloses a three-roller mechanism of a carding machine.
[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

The upper roller is located above the lower roller, and there is a gap between the upper roller and the lower roller. The stripping roller is located on one side of the upper roller. A cotton web supporting plate is provided. The cotton web supporting plate is polygonal and is located between the stripping roller and the lower roller. The cotton web supporting plate has a first side edge and a second side edge. The first side edge is adjacent to the stripping roller, and the second side edge is adjacent to the lower roller. The first side edge and the second side edge intersect at an acute angle and face the upper roller. A cleaning roller and a first suction hood are provided. The cleaning roller is located on one side of the stripping roller. The first suction hood has a first hood wall and a second hood wall.
